On December 8th, the State Council Joint Prevention and Control Mechanism held a press conference to introduce the situation of further optimizing the implementation of epidemic prevention and control measures and answer media questions.

Graded and classified treatment

How do medical institutions do a good job in graded and classified treatment of key populations?

Guo Yanhong, director of the Medical Emergency Department of the National Health and Wellness Commission, said that in order to make overall plans for the layout and utilization of medical resources, the key point is to do a good job in the medical treatment and management of those who are seriously ill and have serious risk factors in COVID-19, and we have classified and treated those infected with COVID-19 virus.

First, for mild and asymptomatic infected people, those who have no basic diseases or whose basic diseases are in a stable period, they can take care of themselves at home.

Second, this part of patients with severe illness or serious risk should be admitted to designated hospitals. In order to ensure the treatment of this part of patients with severe illness or serious risk, we require that hospitals with strong comprehensive ability and high treatment level should be selected as designated treatment hospitals, and at the same time, they should be equipped with strong medical staff.

Thirdly, there are still some patients who have basic diseases or are mainly suffering from other diseases and go to general hospitals or specialized hospitals for treatment. In the process of treatment, they may be COVID-19-positive after testing. For these people, we have asked general hospitals and specialized hospitals to set up buffer zones, whether in outpatient, emergency or inpatient areas, so as to ensure that these patients can be treated and meet the needs of people’s medical services.

What kind of symptoms do you need to see a doctor in a medical institution?

Wang Guiqiang, director of infectious diseases department of Peking University First Hospital, said that if the following five situations occur, it is recommended to contact community doctors. If the illness is serious, you can contact 120 to go to the hospital for diagnosis and treatment.

The first situation is dyspnea or shortness of breath.

The second situation is that after drug treatment, you still have a fever. If it exceeds 38.5 degrees Celsius for more than 3 days, you should go to the hospital.

The third situation is that the original underlying diseases are obviously aggravated. For example, when the medication for hypertension is uncontrollable, the medication for diabetes is uncontrollable or there are other critical risks, you must go to the hospital for treatment in time.

The fourth situation is that children have some drowsiness, refusal to eat, diarrhea, vomiting, etc., which will not be relieved after treatment, and they will have to go to the hospital for treatment for more than two days.

The fifth is that pregnant women have headaches, dizziness, palpitation, shortness of breath or abnormal fetal movement, etc., and they should also go to the hospital for further diagnosis and treatment. Read the original > > >

nucleic acid testing

From what aspects has the scope and frequency of nucleic acid detection been reduced?

He Qinghua, a first-class inspector, said that further optimization measures require further optimization of nucleic acid detection, emphasizing that nucleic acid detection should focus on areas and personnel with high risk of infection, mainly reducing the scope and frequency of nucleic acid detection from the following aspects:

First, not to carry out all-staff nucleic acid testing according to administrative regions.

Second, except for special places such as nursing homes, welfare homes, medical institutions, child care institutions, primary and secondary schools, negative proof of nucleic acid testing is not required.

Third, cross-regional migrants will no longer be examined for negative nucleic acid test certificates or health codes, and landing inspections will no longer be carried out.

Fourth, according to the needs of epidemic prevention work, antigen testing can be carried out.

In addition, it is also required to carry out nucleic acid testing for employees in high-risk positions in accordance with the relevant provisions of Article 20 optimization measures, and the scope of nucleic acid testing shall not be expanded.

Employees in high-risk positions mainly include:

What are the special places that need to provide negative nucleic acid certificates and health codes?

He Qinghua, the first-class inspector of the Department of Transmission and Prevention of the National Bureau of Disease Control and Prevention, said that although the pathogenicity of the mutant strains in Omicron is obviously weakened, the risk of serious illness is higher for the elderly and key people with basic diseases, especially those who live in nursing homes and welfare homes, as well as places where special people are concentrated, such places are prone to cluster epidemics once the source of infection is introduced, so it is necessary to provide negative proof of nucleic acid testing for foreigners entering these special places. People who enter other general places, including those who take public transport and cross-regional migrants, do not need to provide negative proof of nucleic acid test, nor do they need to carry out landing inspection, but they should do personal protection, wear masks regularly, and reduce gathering and interpersonal contact. The new 10 measures also suggest that large enterprises and some specific places can determine some prevention and control measures by themselves, and all localities can take targeted measures according to the local epidemic situation. At the same time, it is mentioned in the 20 measures that "one enterprise, one policy" and "one park, one policy" can be adopted for the prevention and control of some key enterprises, and the new 10 measures are a further continuation and update of the 20 measures.

How often do employees in high-risk positions need to carry out nucleic acid testing?

Wang Liping, a researcher at the Center for Disease Control and Prevention of China, said that according to the ninth edition of the prevention and control plan and 20 optimization measures, the employees in high-risk positions are mainly divided into two categories:

The first category is extremely risky, which refers to the entry personnel, goods, people in direct contact with the environment, staff in centralized isolation places, medical staff in designated medical institutions and fever clinics in general medical institutions,They are required to conduct closed-loop management during the operation and conduct nucleic acid testing every day;

The second category refers to some employees who are closely related to residents’ lives, such as Shangchao, Express Delivery, Takeaway, etc., who have intensive working environment, frequent contacts and strong mobility. For such people, we should also do a good job in monitoring and nucleic acid testing.Nucleic acid testing is required twice a week.

home quarantine

What factors should people consider when choosing home isolation and centralized isolation?

Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, said that close contacts need some basic conditions to choose home isolation: it is best to have a separate room and good ventilation; If you share the bathroom, you should do a good disinfection treatment; If the family stays at home independently, they should be able to take care of themselves in life; People at home must stay indoors and refuse all kinds of visits. In this case, we still suggest that close contact with people can be isolated at home.

We emphasize that when we are isolated at home, if there are elderly people, infants and so on who need to be taken care of at home, then we should pay attention to personal protection to avoid potential transmission risks, and we should wear masks and do a good job of hand hygiene. At the same time, antigen testing should be carried out every day, and once it is positive, it should be reported in time. At the same time, do self-monitoring after being positive. When it is negative, you should also do a good job of daily self-symptom monitoring, including whether you have fever, cough and shortness of breath. If these manifestations appear, you should also report them to the community in time.

The elderly, pregnant women, infants and people suffering from basic diseases such as cardiovascular diseases must report to the community in time for special needs, including medication and treatment, when observing at home. In case of emergency, they should also seek medical treatment in time.

How to do personal protection for isolated people at home?

Wang Guiqiang, director of the Infectious Diseases Department of the First Hospital of Peking University, said that it is necessary to do a good job of personal protection for isolated people at home, and keep as little contact with family members as possible, and keep a certain distance if they contact. Include the following points that we emphasize:

First, the living room should be ventilated every day, and good ventilation is very important to reduce the spread of respiratory infectious diseases.

Second, the bathroom, bathroom, if it is best to use it alone, it should be disinfected every day. If it is shared, it must be staggered, and it should be disinfected well after use to avoid family transmission.

Third, do a good job in hand hygiene and environmental disinfection, including paying attention to hand hygiene during cooking and dining.

Fourth, when coughing or sneezing, be sure to cover it with a paper towel and throw it into the trash can to avoid the potential risk of aerosol transmission caused by splashing.

Fifth, used paper towels, masks, disposable gloves and other household garbage are put into plastic bags and placed in special trash cans.

Another thing we should pay attention to is that personal items should not be mixed and separated from family members as much as possible, because the items themselves may also pose the risk of virus transmission.

If the medical staff are infected with Covid-19, will they be treated at home or continue to work?

Guo Yanhong, director of the Medical Emergency Department of the National Health and Wellness Commission, said that medical staff is a very special group. Due to their special positions, they will receive a large number of patients every day, so they face the highest risk of infection and the work is very heavy. It can be said that occupational exposure is inevitable.Once medical personnel are infected with Covid-19, they should also follow the relevant requirements of the "New Ten Articles".However, in order to minimize the occupational exposure risk of medical staff, we put forward a series of requirements for the management of medical institutions.

Sealing and control measures

Units and buildings with "mixed pipe positive" detected no longer need to be sealed?

Wang Liping, a researcher at the Transmission and Prevention Department of China CDC, said that when the mixed tube is found to be positive, the relevant departments will inform the mixed inspection personnel as soon as possible, so that they can implement the local isolation measures, and at the same time, they will arrange personnel to take samples at home for review as soon as possible.Therefore, people in the same building and unit as those who are positive for mixed inspection do not need to be temporarily blocked.

When the recheck results are all negative, the mixed inspection personnel will immediately remove the isolation measures. However, if the door-to-door recheck results are positive, the control measures should be implemented in time, and the close contact should be controlled in time according to the results of field investigation and risk judgment, the risk area should be delineated, and the relevant epidemic situation should be handled well. Read the original > > >

Can only one positive infected person be detected without delineating high-risk areas?

Wang Liping, a researcher at the Center for Disease Control and Prevention of China,For the case that only one case is detectedIf the risk of communication in his work place, residence and activity place is relatively low, and after the secret connection is controlled in time, there is no risk of community communication after judgment, at this time, it is not necessary to delimit high-risk areas.

For a large number of households, a unit or a building may have hundreds of households.According to the current situation and risk judgment, according to the new ten articles, only the floors or households with high exposure risk can be judged to minimize the inconvenience caused by the epidemic to people’s lives.

After the high-risk area is demarcated, if no new infections are detected for five consecutive days, the seal can be released in time to avoid long-term seal control.. The new article 10 also mentioned that people with asymptomatic infection, mild illness or even close contact can choose home isolation. Therefore, it is very likely that there are some people in the community who are sealed off. For the newly infected people who are detected in the high-risk area after the risk area has been sealed off, if they live with the positive people who are strictly quarantined at home or are close to each other, there is no risk of community transmission outside the home after the judgment. In this case, even if they are positive, it will not affect the time to unseal the whole high-risk area, and they will still be unsealed without new ones for five consecutive days.

Vaccination for the elderly

Why do the elderly need vaccination?

Xia Gang, Director of the Department of Health and Immunization, said that the current epidemic situation is still severe and complicated, and vaccination still has good effects in preventing severe illness and death. Vulnerable people such as the elderly can easily develop into severe illness, critical illness and even death after being infected with Covid-19, and vaccination with COVID-19 vaccine will benefit the most. There are quite a few disabled and semi-disabled elderly people in China who live at home for a long time and rarely go out. However, they may still be infected during the company or visit of relatives, which may lead to illness or even serious illness and death. Therefore, it is still necessary to vaccinate.

According to Xia Gang, according to research, compared with young people, the risk of serious illness after COVID-19 infection is 5 times, 7 times and 9 times respectively, and the risk of death is 90 times, 220 times and 570 times respectively. If the elderly over 80 years old are not vaccinated with one dose, their risk of death is about 14.7%; If one dose of vaccine is inoculated, the risk of death will be reduced to 7.16%; If three doses of vaccine are inoculated, the risk of death will be reduced to 1.5%. Compared with no vaccination, the risk of death decreased by 9.3 times after vaccination with 3 doses. Read the original > > >

What services and conveniences will be provided for the elderly when they are vaccinated?

Xia Gang introduced that in view of the mobility of these elderly people, in order to enable them to vaccinate more conveniently, we have continued some previous good practices, including using mobile vaccination vehicles, opening special vaccination sessions for the elderly and opening green channels for vaccination for the elderly. At the same time, it is also suggested that all localities can send medical personnel with rich experience in diagnosis, treatment and vaccination to form vaccination teams, carry common equipment and medicines needed during observation after vaccination, and provide home vaccination services for disabled and semi-disabled elderly people, so that these elderly people can complete vaccination without leaving home.

CCTV News:Recently, the problem of sulfur dioxide exceeding the standard in Linfen City, Shanxi Province has aroused widespread concern. As a typical resource-based city in the north, the ambient air quality in Linfen City has turned sharply since the winter of 2016, and heavy smog weather has continued to appear. Up to now, Linfen City has experienced six heavy pollution weather processes, which lasted for 48 days and issued 13 heavy pollution weather warnings. On January 4, 2017, the air quality index (AQI) of monitoring points in Linfen City continued to rise, and the concentration of SO2 (sulfur dioxide) was as high as 1,300 μ g/m3, exceeding the national third-class standard ("minimum requirements for people to be exposed to acute health damage in the short and medium term") by more than 1,000, ranking first in 388 cities in China, 719 higher than the second.

On the 15th, Shanxi Provincial Environmental Protection Department announced that after three days’ investigation and analysis, the joint expert group of the Ministry of Environmental Protection and Shanxi Province has preliminarily identified five reasons for the excessive concentration of sulfur dioxide in Linfen:

First, coal consumption is large.From 2013 to 2016, the city’s coal consumption in Linfen increased from 30 million tons to 36.6 million tons, of which coking coal accounted for a high proportion, accounting for 65.3%, followed by power generation coal of 9.7 million tons, accounting for 26.5%.

Second, residents’ loose coal combustion emissions have aggravated sulfur dioxide pollution in winter.According to preliminary estimates, the annual sulfur dioxide emissions from coal-fired heating (except cogeneration) in six counties and cities (districts) along the Fenhe River in Linfen City are about 38,000 tons, accounting for 45% of the annual sulfur dioxide emissions. When winter enters the heating season, the proportion is even more prominent, accounting for about 70%. Among them, the emissions from heating boilers other than cogeneration account for 13% of the living sources.

Third, the promotion and use of clean coke did not achieve the expected results.Although clean coke is widely used in urban areas, due to its high burning point and difficulty in bank up, some people abandon the distributed clean coke, some mix clean coke with inferior coal, and a small number of clean coke fail to meet the sulfur index, and the amount of sulfur dioxide emitted by residents in urban areas and surrounding areas is still large.

Fourth, the transformation of coal-fired heating boilers and clean energy lags behind.At present, there are still 86 130-ton coal-fired boilers in urban areas, and there are basically no desulfurization measures. Although clean coke is used, the sulfur dioxide emission is still very large, which has a direct impact on the sulfur dioxide index in urban areas.

Fifth, there is no on-line monitoring for central heating in Dongcheng, the desulfurization device is ineffective, the factory area is messy and the management measures are not in place.(CCTV reporter Hu Xiaodong)

　 　 Special feature of 1905 film network In fact, the concept is not new, not to mention the amazing short film. In 2012, the animated film invited the protagonists of the game and turned it upside down. Up to now, Sony’s "Pixel Wars" has taken the road of combining real people with CG. Comedy stars such as adam sandler, kevin james and Josh Gad are invited. Obviously, the film didn’t want to be normalized from the beginning, and it was played in the guise of "war" and alien invasion, but it was still a shit and Loser transformation. It was not interesting or harmful.

　 　 At the beginning of the film, the film played a card of feelings and memories. Several strange-looking little boys, one of whom lost how to play the game, and the other, although brave, was defeated by others in the final championship battle. The other likes to chat with the girl in the game machine, full of small and medium-sized Xuan Xuan. Obviously, the film is paving the way, and it is also a common routine of Hollywood movies. Everyone’s adult life is greatly influenced by his childhood, so-called psychological trauma. So, the runner-up of the game, carrying the shadow of the second place, grew up to be an ordinary employee of a home appliance company, while the little fat man with no ambition and only catching dolls became the president of the United States. Yes, you are not mistaken. What is the screenwriter’s brain wide open for irony? Another "little devil" got into the panic, and the geek who is infatuated with beautiful women, as always, started a technical otaku.

　 　 When the scene jumps to the present, when adam sandler comes out, the whole style of painting is wrong, not to mention that kevin james has become the boss of the United States. From this time on, the tone of the film is slightly ironic and teasing. After watching such low-cost comedies in the United States, you will be quite familiar with and benefit from all kinds of jokes and techniques, such as ridiculing the American president to pieces and not knowing the "disaster". Isn’t it obvious that the president has no education? In addition, all kinds of important people in the White House have also become the object of ridicule, portrayed as a group of straw bags, officials are not like officials, and the general seems to be half buried in the ground. Of course, Americans haven’t forgotten to give a black hand to their good brother Britain again. The female prime minister has become thin and toothless, and looks like a menopausal woman with hormonal instability. She is not only pale but also very neurotic, which makes people think of her naked contempt for the Queen of England. Behind these satire and ridicule, what we can actually see is the characteristics of the film Pixel Wars, or the serious hooliganism as mentioned above.

　 　 Therefore, after adam sandler saw the heroine’s swaying posture, the first sentence she blurted out was "Wow", a heartfelt surprise brought out by hormones, and then the heroine happened to be in the emotional loss stage of life. Two people flirted and secretly fell in love, but they did not expect to start bickering because of a misunderstanding of a kiss, and they began to stage the plot of tell it to the judge. This way of communication between men and women is obviously the favorite of this kind of comedy, and they don’t like each other. Of course, adam sandler is not the only serious hooligan. Otaku still thinks about the dream girl in his game, and even draws many cartoons full of psychosexuality. One of the conditions for the little devil to join the team against alien aggression is to have dinner with tennis superstar Serena and spend the night together.

　 　 The more the film goes to the back, the stronger the desire of these men for women, and the creator has generously satisfied all their wishes. After becoming a salvation star, adam sandler won the beauty home, and the cartoon goddess of the otaku was regarded as a reward for the victory of the game, and became a real person, and Serena was waiting for the sandwich night that the little devil was thinking about … … It can be seen that these women were rewarded as trophies to these geeks, so when the beautiful game goddess in the movie dropped her double swords and leaned over to kiss the fat and filing otaku, the boys in the audience couldn’t help but make a sound with multiple meanings of regret, envy and jealousy.

　 　 It can be seen that "Pixel Wars" is like a beautiful world that a bunch of game geeks fantasize about themselves. In this world, not only can they become superheroes, but the opponents they beat are actually BOSS, who often can’t get through customs in the game, and then save the world. By the way, they also saved the setting that they have been a loser for the first half of their lives, and finally they can even win the beauty. Therefore, it is not surprising that the film is full of all kinds of imagination about beauty, hero and strength. After all, for the game otaku, the imagination of the external world is always better than the reality, otherwise Serena, a world champion who is strong and independent both physically and mentally, can’t throw herself at a cheating game champion.

　 　 It is precisely because of this that the audience of this "Pixel Wars" is estimated to be very limited. After all, the value position of such male chauvinism and taking all women as trophies is really out of line with the prevailing trend of feminism, not to mention that all the women in the movie are beautiful and amazing, while all the men seem to be a little diabetic.

"Pixel Wars" is such a typical American brainless comedy. The concept of pixels in the old-fashioned game of the film to create alien attacks is somewhat interesting in itself, but it is only limited to this. Wasted the setting and nostalgia that this attack method is electronic and gamified. On the one hand, the game characters in Pixel are much richer, and the story in the movie is still from a human perspective. On the other hand, they are all set as villains who will only destroy or even show their faces and break into slag, destroying their childhood and feelings in the game hall with steel.

　

This week, OPPO announced the latest technological progress in AI, performance, communication and privacy security, including the first handset/hands-free dual-mode satellite call for smart phones, the first 7 billion-parameter large model for end-side applications, the tidal architecture that debuted and many other cutting-edge technologies.

The brand-new technology portfolio announced this time will fully implement the next-generation flagship product Find X7 series, set a brand-new technical benchmark for the flagship mobile phone in 2024, and bring consumers an innovative flagship experience that refreshes standards.

Release handset/hands-free dual-mode satellite call, leading the evolution of satellite interphone to satellite mobile phone.

OPPO released the satellite antenna pattern control technology, which will realize the innovative experience of handset/hands-free dual-mode satellite call for the next generation flagship. This technology can dynamically adjust the radiation pattern of satellite antenna, make the antenna beam aim at the satellite dynamically, and ensure that users can keep connected and talk with the satellite in both handset and hands-free conversation postures.

Lu Bao, a terminal antenna expert in OPPO hardware engineering, said: "We are very happy to realize the latest breakthrough in satellite antenna technology in the next generation flagship product for the first time through continuous research and accumulation and using a series of innovative technologies and patents. Through satellite communication technology and fully upgraded antenna, smart communication and near-field communication technology, we expect users to get a reliable communication experience in the whole scene. "

The traditional satellite communication mobile phone adopts single antenna design, and it can’t meet the demand of transmitting power in the head-to-hand state. It can only support the use of hands-free mode, which will lead to problems such as unclear communication in harsh weather environment such as strong wind.

OPPO’s brand-new handset/handsfree dual-mode satellite call makes the mobile phone satellite call experience evolve from "satellite intercom mode" to "satellite phone mode" which accords with users’ intuition for the first time, helping users to obtain more efficient communication efficiency in extreme environments.

The industry’s first end-to-end application of the 7 billion parameter big model, the big model mobile phone entered the fast lane.

Facing the rapid development of large-scale model technology, OPPO officially launched the large-scale model of self-training in ODC — — After AndesGPT, it was also announced that the industry’s first 7 billion-parameter model of end-side application will be realized on Find X7 series.

Through the model compression such as high-precision 4-4bit quantization, the acceleration of reasoning engine and the hardware acceleration mode of deep cooperation with chip platform,For the first time, it brings a complete 7 billion-parameter large model to the mobile phone terminal, completely changing the way of using the mobile phone terminal AI.

Zhang Jun, general manager of OPPO Software Innovation Center, said: "OPPO’s self-trained and personalized big model — — AndesGPT contains many versions of parameters from one billion to one hundred billion, with abundant knowledge, infinite memory and good use of tools. The technical architecture of end-cloud collaboration can support diversified application scenarios.

With the cooperation of various technologies, we will also apply a large language model with 7 billion parameters and a generative visual model to the Find X7 series for the first time, which will bring a local AI experience with faster response, stronger processing ability and higher generation quality while ensuring the privacy and safety of users. "

Thanks to the complete ANDES GPT 7 billion-parameter large language model applied by end-side, Find X7 series will bring the next generation AI experience such as natural language understanding, text content summary and call voice summary.

Compared with other models on the same platform, oppoandesgpt 7 billion parameter large language model can bring 20 times faster response in the generation of 200-word prefix, and 2.5 times faster for the generation of 2000-word prefix.

At the same time, OPPO’s AndesGPT can achieve the maximum number of abstract words of 14,000, which is 3.5 times that of other models on the same platform. In terms of generation quality, compared with the 1 billion parameter model, the ANDES GPT 7 billion parameter large language model has a higher "IQ" understanding ability, which brings a more complete and accurate record to the call summarization ability.

OPPO also announced the AndesGPT generative visual model based on self-training, which will bring image semantic understanding, subject recognition and segmentation, image extension and generation capabilities to Find X7 series, and bring a new functional experience of subject elimination and real-life redrawing. AndesGPT’s generative visual mode brings a wider range of image experience to mobile phones.

Compared with other cloud models on the same platform, AndesGPT can only support human body recognition. ANDES GPT not only supports the recognition and segmentation of more than 120 kinds of subjects, but also can realize hair-level segmentation and multi-agent separation of up to six, as well as the filling and natural generation of super-large-area images, which greatly expands the application scope and practicability of the generative visual model.

In addition, the end-to-end application of AndesGPT generative visual model also brings 60% shorter generation time and higher generation accuracy compared with other models on the same platform, bringing users a more readily available generative visual experience.

Original tidal architecture, breaking through the bottleneck of chip energy efficiency

Facing the more stringent demand of flagship end users for chip energy efficiency, OPPO first announced the exclusive tidal architecture technology. As a technology stack of chip hardware and software integration, Tide Architecture has built a set of chip-level performance solutions from scene recognition, computing power demand, cache matching and computing power scheduling, which solves the problems of memory and computing separation and chip scheduling faced by mobile platforms and realizes the maximum energy efficiency performance of flagship chips.

Hong Hansheng, director of software technology planning and architecture design of OPPO, said: "Tidal architecture is a collection of chip soft and hard fusion technologies developed by OPPO, and it is a chip optimization technology created by a group of people who know chips.

In the past, from the first-level cache to the system cache has always been the technical area of chip design companies. Through the tidal architecture OPPO, it broke through the technical boundary and mastered the use of the third-level cache to the system cache. With the chip-level capabilities in no man’s land and deep water, it brought a great leap in computing efficiency to the flagship products. "

Through in-depth joint research and development with chip manufacturers, OPPO has penetrated the tidal architecture into the on-chip cache system that traditional mobile phone manufacturers can’t use finely, and jointly designed cache partition, dynamic ratio of CPU/GPU and fast channel scheme of clean data with chip manufacturers.

Through the tidal architecture, OPPO realizes the dynamic matching of system-level cache for the first time.Dynamically allocate system-level cache resources for CPU and GPU in real time according to computational tasks and rendering tasks. Through this unique technology, the tidal architecture can achieve an average energy efficiency gain of 8%.

In addition, the tidal architecture also supports a brand-new scene-level computing power and power consumption analysis model on the chip, which can realize the dynamic computing power and power consumption evaluation and analysis based on a single scene, and dynamically disassemble each computing task to the computing power distribution of each computing unit on the chip in real time, find out the best energy efficiency combination, and achieve more competitive energy efficiency performance for diverse user applications.

By accurately and dynamically scheduling the computing power of GPU, Tide Architecture can also control the display delay excellently, and realize an unprecedented continuous and smooth experience for Android flagship. In the test of simulating users to start applications 320 times a day, the standard deviation of Find X7 equipped with tidal architecture is only 11ms, which has achieved a more lasting and stable smooth performance than the same platform and other platforms.

Hong Hansheng also revealed that OPPO has begun to deeply participate in the design of the next generation of Tianqi chips and explore more possibilities of tidal architecture.

Super signal engineering, solving network problems in the whole scene

During the communication meeting, OPPO also announced a set of self-developed communication technology solutions — — Super signal engineering, through antenna technology, intelligent communication and near-field communication, enhances the full-scene communication experience of Find X7 series from outdoor to urban and from urban to indoor.

OPPO brings the highest performance four-antenna architecture to the next generation flagship product through antenna miniaturization technology and spatial distribution optimization of low-frequency four-antennas. By combining low ECC and high isolation technology, OPPO can further improve the throughput of ultra-low frequency four antennas and reduce network delay.

Facing the influence of the grip on the signal strength, OPPO specially designed the low-frequency antenna, built the signal model of OPPO’s self-developed handheld state, improved the signal condition of the mobile phone in the handheld state, and realized the signal strength enhancement of up to 7dB and an average of 3dB.

OPPO’s unique intelligent communication technology utilizes the intelligent computing service provided by Andean intelligent cloud, the industry-leading intelligent fusion link technology and the cross-layer data acceleration capability to realize the acceleration strategy of the combination of Wi-Fi and cellular multi-networks.

In addition, based on communication QoS link technology, OPPO accelerates conference data and improves conference delay through the establishment of 5G boutique private networks of three major operators.

Smart communication technology also brings AI network prediction technology to Find X7 series. By integrating AI technology, communication technology and sensing technology, Find X7 series can predict signals for different spatial forms, intelligently recommend the most appropriate internet use strategy, and provide better performance in scenarios such as short video jam of subway and optimal network probability of switching from home to home.

Through intelligent communication technology, Find X7 series will also support excellent cross-end unified communication. Through Pantanal trust chain technology, Find X7 can realize fast and non-inductive connection between mobile phone and tablet, and based on the self-developed virtual data transmission channel, the tablet has mobile phone network communication capability, and users can make calls, send and receive short messages and access the Internet with data.

Super Signal Engineering will also bring a brand-new near-field communication experience to Find X7. Using the through-the-wall mode of near-field communication, Find X7 dynamically selects the optimal transmission and reception time slots through active noise identification, and improves the anti-interference ability. Combined with radio frequency enhancement technology, Find X7 improves the uplink and downlink rates.

Through the high throughput mode, Find X7 series can use the brand-new bandwidth of 160Mhz for mobile phone moving transmission, and can complete the handling of 180GB content in less than 15 minutes.

Using the dual-antenna packet loss prevention technology, Find X7 series can also bring lower Wi-Fi network delay. Using Wi-Fi& Bluetooth full acceleration 3.0 technology, Find X7 series can solve the data transmission impact of Wi-Fi and Bluetooth in traditional solutions. Compared with other products, this technology helps Find X7 series to reduce the game delay of nearly 150ms and 18 live broadcasts.

Protect security and privacy from software to hardware.

While promoting innovation in AI, performance and communication technology, OPPO always attaches great importance to users’ privacy security, and is committed to building a comprehensive privacy protection system for users through full-link application, data management and control, and innovative functions combining software and hardware.

In order to further enhance users’ privacy protection, OPPO has brought a security solution based on the second-level security chip with the highest security level in the mobile phone industry, which will provide the terminal with the highest chip-level privacy protection.

Compared with the traditional software security scheme, the chip-level encryption method can separate the management and authorization switch of sensitive rights from the operating system and lock it into the hardware layer of the security chip, which is managed by the chip-level security subsystem.

Based on the chip-level privacy security scheme, OPPO has implemented an innovative VIP mode in the folding flagship FindN3. With OPPO’s unique three-stage physical switch, it can quickly and intuitively turn off sensitive permissions such as microphone, camera and positioning, and encrypt user privacy information at hardware level.

CCTV News:Yesterday (October 24th), the data released by the National Bureau of Statistics showed that in the third quarter, China’s consumer market generally recovered steadily, and market sales maintained growth.

The data shows that in the first three quarters, the total retail sales of social consumer goods was 32,030.5 billion yuan, up 0.7% year-on-year, with a growth rate of 1-mdash; It accelerated by 0.2 percentage points in August. Quarterly, it increased by 3.5% in the third quarter, and the recovery in the third quarter was faster than that in the second quarter. In September, the total retail sales of social consumer goods increased by 2.5% year-on-year, of which the retail sales of commodities increased by 3%.

Guo Liyan, Director of Comprehensive Situation Research Office of China Macroeconomic Research Institute:At present, the domestic consumer market is also maintaining a stable trend, especially the potential of consumer demand such as online social zero, some emerging consumption and some green and low-carbon consumption is further released, which also drives the development trend of consumer market to stabilize and recover.

In addition, since the third quarter of this year, the Ministry of Commerce has continuously promoted the implementation of the policy of green smart home appliances going to the countryside, promoted the resumption and development of catering, accommodation and other industries, and created new consumption scenarios through digital empowerment and business travel and cultural integration, giving full play to the role of important platforms such as the international consumption season and stimulating consumption vitality. Beijing, Shanghai, Guizhou, Jiangxi and other places have also promoted the upgrading of consumer demand by issuing consumer vouchers and government subsidies.

1-mdash this year; In September, Shanghai won the title of the first store capital in the mainland with the number of 703 first stores. Recently, a number of first stores have just appeared in the waterfront core area of Shanghai Suhewan. This urban complex, which is incarnated from the historical protection buildings such as the Shanghai-style Shikumen building "Shenyuli", presents a rambling consumption experience after ten years of renovation. Among more than 140 brands, more than 70% are the first stores in China, the first in Shanghai and the first in the region.

Near the end of the year, with the opening of several heavy projects, Shanghai will continue to develop the starting economy, brand economy and tax-free economy, and cultivate a number of leading local brands and new online brands. It is expected that Shanghai will introduce more than 800 first stores this year. In Guizhou, since the third quarter of this year, a total of 113 million yuan of travel coupons have been issued to consumers inside and outside the province, which has driven the growth of travel consumption. In Zunyi City, 304 enterprises or merchants involved in tourism, catering, accommodation and retail have been included in the designated use points of cultural travel coupons.

Not long ago, Mr. Chen saw a novel thing on the Discovery Channel: Americans put a blocking bed at the end of some airport runways, which actually prevented planes from rushing off the runways. On the TV screen, the materials paved at the end of the runway successfully prevented a Boeing passenger plane from rushing out of the runway, which protected the plane and ensured the safety of passengers.

The technology presented in the picture is called Engineering Material Arresting System (EMAS), which has long been monopolized by foreign companies. On July 12th, 2012, EMAS, developed by China Civil Aviation Science and Technology Research Institute and with completely independent intellectual property rights, officially passed the qualification examination of Civil Aviation Administration of China and was approved for engineering application. This is an important progress made by China Civil Aviation in the research and development of major systems related to flight safety, and it is also the second EMAS in the world to be approved by government civil aviation authorities. The achievement of this achievement will greatly reduce the cost of installing the system in airports, thus promoting the effective improvement of safety and security capabilities of many plateau airports and airports with special terrain in China.

How to stop the plane from running off the runway?

With the rapid development of the world’s civil aviation industry, the number of take-off and landing flights has increased significantly, and the number of aircraft rushing off the runway has shown an upward trend. How to avoid serious accidents after the aircraft rushing off the runway has become an important issue for civil aviation safety. In order to solve this problem, as early as the 1960s, the British began to research and develop related technologies to stop planes that ran off the runway, but failed to form products for various reasons. By the 1980s, the Federal Aviation Administration (FAA) and an American company began to jointly develop the EMAS system.

In fact, EMAS is a kind of foam concrete with specific mechanical properties, which is laid on the ground of the runway extension line with a thickness of several tens of centimeters to form an arresting bed. Its width is consistent with the runway, and its length is between tens of meters and more than 100 meters. Once the plane rushes out of the runway, it enters it, and the foam concrete is crushed under the rolling of the wheels, so as to absorb the kinetic energy of the plane, and on the premise of ensuring the safety of the plane and the people on board, the plane will gradually slow down and finally stop in the arresting bed.

In 1990s, FAA approved the design method of EMAS system. In 1996, the first trial laying was carried out at Kennedy Airport in new york, and three planes were successfully stopped. Subsequently, the FAA issued a license for it and promoted it in civil airports in need in the United States. Up to now, 55 sets of EMAS systems have been laid in 35 civil airports in the United States, and 8 planes have been successfully stopped. At the same time, the United States promotes the EMAS system on a global scale. In recent years, the system has been installed at Jiuzhai Huanglong Airport in Sichuan and Songshan Airport in Taiwan.

Can solve the problem of running off the runway.

Sichuan Jiuzhai Huanglong Airport was built by cutting mountains, surrounded by mountains on three sides. Due to the influence of complex terrain and high altitude, pilots often feel that the runway is short during the flight mission of Jiuzhai Huanglong Airport, especially in rainy and snowy weather. Once the plane lands and stops taking off, there will be back spraying, brake failure or rushing off the runway, and the consequences will be unimaginable. Therefore, in 2006, when Jiuzhai Huanglong Airport carried out the second phase expansion project, two sets of EMAS systems were installed at the north and south ends of the runway respectively.

In China, a considerable number of airports are built by cutting mountains, commonly known as "desktop airports". Although these airports have established runway-end safety zones according to the standards, there are often steep slopes or cliffs outside the safety zones. Once the plane rushes out of the runway-end safety zone, the tragedy of plane crash and death will inevitably be staged. In addition, some airports in Linjiang, Linhai and residential areas also have such problems.

With the rapid development of civil aviation in China, the number of flights has increased dramatically. In order to maintain the past safety level, we need updated safety measures. According to the statistics of ICAO, the number of runway accidents in the world ranks first in the statistics of civil aircraft accident types. In recent years, the number of incidents of civil aviation rushing off the runway in China also ranks first in the statistics of serious accident symptoms of civil aircraft. It can be seen that the installation of EMAS system in the airport where the safety zone at the runway end is not long enough can solve the problem of the plane rushing off the runway and obviously improve the safe operation level.

Technical problems of

Before the EMAS developed by the China Academy of Civil Aviation Science and Technology was approved by the Civil Aviation Administration of China, there were no similar products in China. If we want to install it in our airports, we need to face three problems: high product price, long transportation distance and difficult system maintenance.

It is reported that in 2010, Taiwan Songshan Airport plans to lay a set of this system, with a budget as high as NT$ 430 million. Compared with 2006, when the system was laid at Jiuzhai Huanglong Airport in Sichuan, the price has increased significantly. Such a high cost, even if the government gives most subsidies, it is difficult for small and medium-sized airports in China that need to install EMAS system most.

China needs its own EMAS system! In 2010, under the direction of Li Jian, deputy director of the Civil Aviation Administration, the Academy of Aeronautics and Astronautics organized a research and development team headed by its main leaders and attended by dozens of scientific research backbones, and relevant units in the United Nations invested tens of millions of yuan. After more than two years, the technical problems of material production and system design methods have been overcome. In order to effectively verify the performance of the product and the safety of the system, the Institute of Aeronautics and Astronautics designed and built a special test bench, conducted dozens of tests on the process of wheel rolling materials, and obtained a lot of valuable data, and finally established a set of perfect simulation calculation model and design method for the blocking process. The Academy of Aeronautics and Astronautics also specially purchased a Boeing 737 aircraft from Air China. Since the fourth quarter of 2011, it has carried out six large-scale real aircraft verification tests using the second runway of Tianjin Airport. The test results show that the EMAS system developed by the Institute of Aeronautics and Astronautics has an effective blocking effect and can ensure the safety of the aircraft and the crew.

Development prospect of

"For China’s civil aviation, the EMAS project is a brand-new and groundbreaking project, and only the United States has mastered this technology in the world. We don’t have any experience to learn from. Doing this project well is of great significance for China civil aviation to export standards to the international civil aviation community, to enhance the international status of China civil aviation, to enhance the safety margin of complex airports, and to build a strong civil aviation country. " Li Jian, deputy director of CAAC, has repeatedly emphasized the importance of China Civil Aviation in developing its own EMAS system.

The responsible person of Academy of Aeronautics and Astronautics (Beijing) Science and Technology Development Co., Ltd. revealed to the reporter that the successful research and development of domestic EMAS system has greatly reduced the laying cost, and provided reasonable engineering solutions for many plateau airports, airports with complex terrain and other airports that are difficult to extend the runway safety zone for special reasons. It has a very broad market prospect. Tengchong Airport has decided to install EMAS system, and many airports at home and abroad have also shown strong interest in this product. "We have more than 10,000 square meters of production workshop in Tianjin Airport Economic Zone, which can meet the environmental requirements for the production and maintenance of blocking materials, and can ensure the stability of material performance, and can produce one set of materials required for EMAS system every month."

This year, ICAO will put forward the standard of increasing the length of the safety zone at the runway end in the "International Standards and Recommended Measures" to reduce the serious flight safety accidents caused by running off the runway. However, due to geographical or other environmental constraints, many airports are difficult to meet the new requirements for the length of runway safety zone. EMAS has been written into Article 3.5.5 of Airport Design and Operation, Volume I, Annex 14 of ICAO Convention on International Civil Aviation, which has become an internationally accepted equivalent safety measure.

It is understood that although the price of domestic EMAS system has dropped significantly compared with similar products abroad, it is also a huge expense for many airports, especially small and medium-sized airports. In view of the purpose of laying EMAS system to improve the safety of airport operation, CAAC is working on formulating relevant subsidy policies to support the popularization and application of EMAS system.

　　● With the increasing popularity of self-help outdoor tourism, outdoor clubs, donkey friends clubs and go on road trip clubs frequently publish tourism products illegally through WeChat groups or QQ groups, publicize tourism routes, and receive citizens or donkey friends to travel.

　　● According to the relevant provisions of the Tourism Law, it is illegal for non-tourism enterprises and individuals to organize tourism activities by themselves.

　　● To completely eradicate the chaos of compulsory consumption of low-priced groups, we should rely on the law, increase punishment measures, and increase illegal costs and rights protection benefits.

　　□ Our reporter Zhao Li

　　"Since you have chosen a group with shopping links, you need to spend. What was your attitude towards me in the shop today? They’re all fighting guerrillas in there! Now get off and go to the store, and spend 20,000 yuan an hour … …” These words came from a female tour guide in Guilin.

　　This female tour guide brought a group organized by a beauty brand. According to tourists, "Give a product gift of 598 yuan to the travel agency", and you can go to Guilin from Hunan for free. On the last day of the trip, due to the high consumption of jade shops, the consumption of tourists did not meet the "psychological expectation" of the tour guide, so the above scene appeared.

　　After this compulsory consumption incident was exposed, the "low-priced group" once again attracted attention.

　　With the increasing popularity of self-help outdoor tourism, it is not uncommon for outdoor clubs, donkey friends clubs, go on road trip clubs, health care products sales enterprises and some training institutions to illegally publish tourism products, publicize tourism routes and receive citizens or donkey friends to travel through WeChat groups and QQ groups. According to the relevant provisions of the Tourism Law, it is illegal for non-tourism enterprises and individuals to organize tourism activities by themselves. However, according to the disclosure of relevant departments, many tourism activities attract consumers to join the group with "low-cost group tours" or even "zero group tours".

　　Through unannounced visits to such organizations that operate travel agencies without travel qualifications, the "Legal Daily" reporter found that many low-priced groups hide many tricks.

　　Ostensibly claiming not to be profitable.

　　In fact, hidden invisible consumption.

　　Recently, the reporter found a large number of QQ groups of related organizations through online search, and the format of group names is simple and consistent: ×× Outdoor Club. The reporter tried to apply to join the QQ group of these outdoor clubs as an outdoor sports enthusiast, but the pass rate was extremely low. Many applications for joining the group are "sinking into the sea" after they are issued. Some organizations directly rejected the reporter’s application for joining the group. For example, the ×× Shanshui Outdoor Club refused on the grounds that it was not introduced by acquaintances in the group after the reporter repeatedly applied for joining the group.

　　After many attempts, the reporter finally entered the individual group chat as an ordinary tourist, but after joining the group, the relevant responsible persons of these organizations will know the information of the new group users, such as "Who introduced them", "Where did they come from" and "What activities have they participated in before".

　　At present, the QQ group of "Beijing XX Outdoor Club" has 1436 people, and it promotes itself as an outdoor adventure club with the theme of mountaineering, hiking, camping, grassland riding, desert crossing, forest adventure, seaside swimming, photography, skiing, food, singing and making friends. The outdoor activities of this club are rich and varied, and most of them are short-lived, generally divided into one-day activities and two-day activities. The prices of short-term activities are generally low. Many one-day activities cost less than 100 yuan, and some two-day activities cost around 300 yuan. Take the one-day tour of Kingfisher Valley (located in Yanqing, Beijing) as an example. The activity cost is 65 yuan/person, including car charter, expressway fee, master fee and outdoor insurance. The activity was held on June 15th. By 15:30 on June 14th, more than 50 people had signed up.

　　The person in charge of the club explained to the reporter: "The expenses incurred by the activity are all AA system, without any additional benefits."

　　Two years ago, Ms. Wang, a citizen of Beijing, was dragged into an outdoor tour group, which published many low-priced tour routes. "People who organize tours say that if they don’t make money, they just organize everyone to go out to play." But Ms. Wang found that they "have not earned less money."

　　She once took part in a trip to Zhangjiakou, the cost was not enough for 300 yuan, but after getting on the bus, the hidden cost began. The organizer charged each tourist 50 yuan’s hard work and each tourist had to pay 10 yuan’s tea fee after the meal.

　　"Without a formal contract, it is too informal for such a tour group to transfer money through WeChat or pay by punching in." Ms. Wang said.

　　Some insiders also revealed to reporters that some outdoor clubs often attract friends to travel under the banner of non-profit, and the relevant personnel of the club make profits through the price difference. Because outdoor clubs don’t need to pay deposits and taxes like travel agencies, the operation of outdoor clubs is almost "zero cost".

　　The reporter interviewed Mr. Zhang, a staff member of a scenic spot who is in charge of receiving these clubs. He said: "The profits of related expenses can basically be divided into four or six with the organizers, and the commissions taken by general travel agencies or tour leaders are more."

　　The promoter declares that he is not responsible.

　　Tourists face greater risks.

　　Another "Beijing Lvyou ××" QQ group information shows that it was founded on October 23, 2015. At present, it has 2,862 members and has organized 44 activities. The organizer is "Beijing× Wolf Outdoor". The activity destinations are nearly Shuanglong Gorge, Pofengling and Dongling Mountain in the suburbs of Beijing, and as far away as Wuyuan, Dunhuang and Mohe.

　　According to the information of official website in Beijing × Wolf Outdoor, this organization is "dedicated to the tent rental industry in Beijing (Tianjin)", and its business scope mainly includes various outdoor goods rental businesses such as Beijing (Tianjin) camping tent rental, cotton sleeping bag rental, down sleeping bag rental, walkie-talkie rental and mountaineering bag rental.

　　The official website page of Beijing × Wolf Outdoor has also set up a column of "Journey Friends Activities". Open this page, which shows 70 pieces of relevant travel information released by this organization from June 6, 2017 to October 24, 2018. The reporter opened several links, most of which are related introductions such as tourist routes, itinerary planning and cost range, and occasionally a "disclaimer" is attached to the introduction. Disclaimer said: The initiator of the activity is only the contact person of the activity, and may not have participated in the training of outdoor leaders and field rescue. Although it is obligatory to help every participant, the initiator and leader of the activity are not responsible for any damage and consequences caused by participating in the activity — — Sign up voluntarily at your own risk.

　　Such a disclaimer can also be found in the details of the activities of the "Beijing donkey friends ××" QQ group.

　　The reporter found that the Mountain X Outdoor Club has also organized outdoor travel activities many times. According to a tweet from its WeChat WeChat official account on June 13th, the length of a seven-day trip is around 3,000 yuan per person. The travel routes include Jiaju Tibetan Village, Hailuogou Glacier, Daocheng Aden, Siguniang Mountain and other popular tourist attractions. The expenses include transportation (driver’s accommodation), accommodation (7 nights), tickets (Siguniang Mountain Shuangqiaogou, Jiaju Tibetan Village, Aden Scenic Area, Hailuogou), meals (breakfast in Danba), tour leader service and insurance. At the same time, it is stated that this line only buys travel accident insurance for players, excluding illness insurance and financial insurance. During the activity, if the financial loss occurs, it shall be borne by the players themselves; If financial losses are caused by personal reasons and need to be handled by themselves, a "departure agreement" needs to be signed.

　　Another go on road trip club, "X Ant go on road trip Club", also indicated similar terms in a go on road trip route push on June 14th. There is only a 500,000 yuan personal accident insurance in the travel expenses, and there is nothing else.

　　The leader of "Beijing × Star Club" told reporters that the price given by his club was "more cost-effective than the travel agency" and an extra accident insurance would be given. When the reporter asked whether to sign the relevant responsibility contract, the team leader replied: "Without signing the contract, the activities are voluntary."

　　Free travel has become a new trick

　　Force shopping to set a trap

　　It is worth noting that related disputes occur frequently.

　　In April 2017, Tian Congxin, an outdoor travel enthusiast, sued the organizer of the WeChat group tour and lost the case. The lawsuit originated in the summer of 2016. He and his friends joined the WeChat group of Happy Friends’ self-help tour and drifted to Daqinggou, Inner Mongolia. During the drifting, he accidentally caused an acute compression fracture of the lumbar spine. When he claimed compensation from the tourism organizer, he was rejected and sued the court. The court ruled that the organizer did not aim at profit, and because Tian Congxin was injured in the wrong sitting position, he took full responsibility.

　　On November 22nd, 2014, Zhang Bingyu followed the coaches of Qingdao Qianli Sports and Leisure Club Co., Ltd. to Jiuxian Mountain for altitude downhill outward bound training. During the descent, the protective rope was untied, and Zhang Bingyu fell from a height of about 30 meters above the ground and died. Yu, an employee of Qianli Sports Company, is the leader of this outward bound training. He knows Cao, whose net name is Mumu, from the outdoor sports group, who was temporarily hired by the company as the outdoor coach of this activity. According to the verdict, both Yu and Cao claimed that they did not have the qualification certificate to engage in downhill activities.

　　Organizations and individuals without tourism qualifications like this often offer various low-cost tours when operating travel agency business.

　　According to a Beijing resident who didn’t want to be named, his parents participated in a low-cost tour organized by the "outdoor donkey friends group" WeChat group. "Everyone has a one-day tour in 50 yuan and Yixing Zhuhai. My parents gather at 6: 30 in the morning and come back with big bags at 6: 00 in the evening. Bamboo shoots, bamboo chopping boards, activated carbon balls, dish towels, etc., spend hundreds of dollars and buy a bunch of useless things. "

　　The reporter interviewed Mr. Zhang, who used to be a tour guide. Mr. Zhang said: "In the tourism industry, low-cost groups basically imply consumption content, which is a default rule in the industry. But if you pay enough money reasonably, there may be only some slight guidance and no compulsory consumption. "

　　Ma Aiping, a professor at beijing international studies university Tourism Management College, thinks that the tour fee for four days and five nights is 598 yuan. If this fee includes food, accommodation and transportation, the price is obviously low, so travel itinerary includes three shopping items.

　　Liu Simin, director of the Tourism Research Institute of the Cultural and Creative Industry Research Center of Beijing Foreign Studies University, believes that there may be many reasons for being lower than the market price and operating cost, but if there are obvious shopping arrangements in the itinerary, it can basically be judged as unreasonable low-cost travel.

　　In 2017, the National Development and Reform Commission, in conjunction with the public security, industry and commerce, price and other departments, continued to carry out a number of actions to comprehensively rectify the order of the national tourism market, and seriously investigated and dealt with illegal acts such as "unreasonably low-cost travel" and "illegally operating travel agency business", and filed 2,595 cases, fined and confiscated illegal income of 33.26 million yuan, and revoked 45 business licenses.

　　Since then, although the related problems of some travel agencies have been contained and supervised to a certain extent, some organizations and individuals who operate travel agencies without tourism qualifications have begun to "move". There are also companies tying health care products during the "zero tour fee" tour.

　　Take Jiufang Joy as an example. This company is not qualified to organize tourism. In August 2018, a fire broke out in Beilong Hot Spring Leisure Hotel in Harbin, Heilongjiang, causing 20 deaths and 23 injuries. According to media reports, Jiufang Joy mainly sells health care products to middle-aged and elderly people, and customers with large consumption can get travel opportunities rewarded by enterprises.

　　According to the disclosure of relevant departments in Beijing, many tourism activities use "zero tour fee" as bait to attract the elderly to join the group, which hides multiple risks. Law enforcement officials of relevant departments in Beijing said that low-cost tours under the guise of "free tours" and "zero tour fees" are becoming more and more hidden, and the elderly often become the "hardest hit areas" for being deceived.

　　According to law enforcement officials, at present, "buying health care products for travel" and "buying wealth management for free travel" organized in the form of companies have become new tricks of criminals, and even some companies cheat in the name of recruiting "tourism experiencers", and applicants encounter compulsory shopping traps when traveling.

　　"WeChat friends circle, clubs, motorists’ clubs and other spontaneous group trips are often personal agreements, and there is no business license. Many irregular behaviors cannot be defined and are in a blind spot of supervision. This kind of tourism behavior is more prone to problems, ‘ Black tour guide ’ The phenomenon of slaughtering customers is even more difficult to detect, which brings difficulties to tourism law enforcement and evidence collection. " Beijing lawyer Liu Chengxian told reporters.　　

Google’s strongest AI model, which has attracted much attention and is considered by the industry to be the most likely to beat GPT-4, has finally appeared!

On December 6th, US Western Time, Google CEO Sundar Pichai and DeepMind Director Demis Hassabis jointly announced the official launch of Gemini 1.0 in official website.

Gemini is jointly created by several Alphabet teams such as Google Research and DeepMind. As a new powerful multi-modal artificial intelligence model, it can induce, understand, operate and combine different types of information. It can not only process text, images, video and audio, but also complete complex tasks in mathematics, physics and other scientific fields, and can understand and generate high-quality codes in various programming languages.

Pichai described Gemini as "our largest and most powerful AI model to date" and said that it has shown the most advanced performance in many leading benchmarks. "The first generation of Gemini 1.0 was optimized for different sizes, namely: Ultra, Pro and Nano. These are the first models to enter the Gemini era and the first realization of our vision when we established Google DeepMind earlier this year. "

At the Google I/O conference in May this year, Pichai spoiled the news that Google was developing Gemini. It is described as the "Next Generation Multi-modal Intelligent Network", which is designed for API integration. It is said that it has trillions of parameters like GPT-4, but its computing power is five times that of GPT-4, and it can perform more complex and diverse tasks.

To this end, Google also merged its two strongest artificial intelligence laboratories: Google Brain and DeepMind, led by Demis Hassabis, the former CEO of DeepMind, and invested hundreds of millions of dollars in research and development of Gemini.

Even sergey brin, the co-founder of Google, who has resigned for four years, has returned to the office of Mountain View in Silicon Valley to participate in the Gemini decision-making and join the LLM scuffle.

But just last week, The Information quoted people familiar with the matter as saying that Pichai recently silently canceled a series of Gemini public appearances that should have been held in California, new york and Washington, D.C., because it was found to be "unreliable in handling some non-English queries", which cast a gray color on the product launch process.

Perhaps to consolidate market confidence, early this morning, Gemini 1.0 suddenly made its grand debut, appearing in the public’s field of vision and quickly occupying the front pages of major scientific and technological media.

So, what is the strongest artificial intelligence model that Google is betting on the whole army?

Hassabis, head of DeepMind, called Gemini their most flexible model, which can run efficiently on all kinds of devices from data centers to mobile devices.

In order to achieve this extensibility, Gemini 1.0 has designed three versions with different functions and sizes:

Gemini Nano —The most efficient model on the end-side equipment. Designed for smart phones, it can perform efficient AI processing tasks without connecting to an external server. Now it has been integrated into Pixel 8 Pro, which can support the function of "summarizing text" in recording applications and the function of "intelligent reply" in Gboard. Starting with WhatsApp, it will be extended to more applications next year.

Gemini Pro —The best model for various tasks running in Google data center. Support the latest version of the AI chat robot Bard from today. It can respond quickly and understand complex queries, which is the biggest upgrade since Bard was introduced. At present, it provides English services to more than 170 countries and regions, and plans to support new languages and regions in the coming months, and apply them to more Google products such as search, advertising, Chrome and Duet AI.

Gemini Ultra -The largest and most powerful model, dedicated to highly complex tasks, will be provided to developers and enterprise customers early next year after completing the current testing phase. At that time, an updated version of Bard Advanced based on Gemini Ultra will be launched.

In terms of model architecture, Gemini still uses Transformer architecture, adopts an efficient attention mechanism, and supports the context length of 32k.

Google confidently said that after rigorous testing and performance evaluation of the Gemini model, from natural image, audio and video understanding to mathematical reasoning,Among the 32 academic benchmarks widely used in the research and development of large-scale language models, the performance of Gemini Ultra has exceeded the most advanced level represented by ChatGPT at present.. Before the release of Gemini, Google conducted a series of tests to evaluate it with standard industry indicators.

In the MMLU test, the score rate of Gemini Ultra is 90.0%, which is higher than that of GPT-4 (86.4%), making it the first model to surpass the performance of human experts. The MMLU test covers 57 subjects, including mathematics, physics, history, law, medicine and ethics, and aims to evaluate the model’s understanding and problem-solving ability in the global knowledge field.

In Reasoning, Math and Code, except HellaSwag, which lags behind GPT-4 by 87.8%, others include challenging math problems such as multi-step reasoning, algebra/geometry/pre-calculus and so on.

In terms of multimodal capability, Gemini Ultra achieved a SOTA score of 59.4% in the new MMMU benchmark test, which exceeded the 56.8% of the multimodal version GPT-4V of OpenAI. This benchmark test spans many different fields and requires precise reasoning for many tasks.

In the image benchmark test, even without the assistance of Object Character Recognition (OCR) system, the performance of Gemini Ultra is better than all previous models only by analyzing pixel information. In audio testing, the scores of automatic speech recognition and automatic speech translation of Gemini are higher than those of Whisper system connected to GPT-4.

Hassabis said that this highlights the superiority of Gemini’s native multimodal. Up to now, the usual way to create multi-modal models is to train individual components of different modes independently, and then splice them together to try to simulate some functions.

Although such models can sometimes effectively perform specific tasks such as describing pictures, they often perform poorly in more conceptual and complex reasoning.

Gemini was originally designed in a native multi-modal way, and was pre-trained in different modes from the beginning using TPUs v4 and v5e chips designed by Google.. Then it is fine-tuned with more additional multimodal data to improve its performance.

This method enables Gemini to understand and reason all kinds of input content more naturally in the initial stage, and its ability in almost all fields has reached an unprecedented advanced level.

First of all, Gemini has complex multi-modal reasoning ability, which can help to understand complex written and visual information and discover indistinguishable knowledge content in massive data.

For example, it is instructed to filter irrelevant papers through the natural language prompt, or extract key data through reading. With a lunch break, Gemini can help you extract 250 document points from 200,000 papers, and further transform the data into any required chart form. This will greatly help to achieve innovative breakthroughs in science, finance and other fields at a digital speed.

The trained Gemini can obviously recognize and understand text, image and audio data at the same time, better understand subtle information and answer questions related to complex topics. This makes it especially good at explaining reasoning in subjects such as mathematics and physics. In the example, the staff showed that Gemini can check handwriting physical mistakes and explain the correct way.

In order to show the multimodal capabilities of Gemini more intuitively, Brother Chai released a video in X, saying that "the best way to understand the amazing potential capabilities of Gemini is to look at their practical applications".

In the video, Gemini taught the staff the pronunciation of "duck" in Mandarin according to the instructions, and also explained the Chinese tone.

The staff also gave Gemini a demonstration of interaction only in Chinese. By asking about the indoor light in a picture, Gemini is asked to give the orientation of the apartment in use. Gemini answers in Chinese and guesses that the room faces south. Circle a plant in the photo and ask what kind of lighting it needs. gemini then explains the plant species and lighting requirements. The whole process is as smooth as the mother tongue, which shows that Gemini is outstanding in multilingual environment, which is no less than GPT-4.

In addition, Gemini can understand, interpret and generate high-quality codes of the most popular programming languages in the world, such as Python, Java, C++ and Go. The ability to achieve cross-language work and handle complex information makes it one of the world’s leading basic coding models, helping programmers to use the powerful AI model as a collaborative tool to design applications.

For developers, starting from December 13th, Gemini Pro can be obtained through the Gemini API in Google AI Studio or Google Cloud Vertex AI. Android developers can also use Gemini Nano, the most efficient model for end-to-end tasks, through AICore.

Looking back on the development of Google’s big model all the way, compared with the continuous and rapid update of OpenAI’s "Wang Fried", Microsoft always seems to be one step behind when it integrates various AI functions of GPT into core products and pushes them to customers. When Bard, a chat robot, was released in February this year, it got off to a bad start, and the market value evaporated by 100 billion dollars overnight with a factual error. Benchmarking Microsoft Copilot’s Duet AI work suite, the market response was moderate, and the financial performance of cloud services also lost to Microsoft.

Especially after the internal friction caused by the reorganization of Brain and DeepMind teams and the loss of senior talents to OpenAI, Google’s AI battle is even more exhausted.

　　Xinhua News Agency, Tehran, September 21st: Talk about "America can’t be trusted" in the eyes of Iranians.

　　Iranian President Leahy made it clear in an interview with the American media a few days ago: "We can’t trust the United States." This sentence is not only his personal opinion, but also the consensus of Iranian society. From a government spokesman to an ordinary librarian, Iranian society now widely believes that — — "the United States cannot be trusted."

　　The formation of this social consensus is closely related to the United States’ treachery and arrogance on the comprehensive agreement on the Iranian nuclear issue. In July 2015, after 10 years of arduous negotiations, Iran reached the the Iranian nuclear deal with the United States, Britain, France, Russia, China and Germany. However, in 2018, despite the opposition of the international community, the United States unilaterally withdrew from the Iranian nuclear deal and once again held high the sanctions stick to "exert extreme pressure" on Iran.

　　The United States’ wanton breach of contract and indiscriminate sanctions have caused great harm to Iran’s development. After the Iranian nuclear deal was reached, the United States lifted sanctions against Iraq, and Iran’s daily average oil export once reached 2.5 million barrels, with a record economic growth rate of 13.6%. However, after the United States unilaterally broke the contract and re-imposed sanctions, Iran’s oil exports once plummeted to only 100,000 barrels per day, and the economy shrank sharply year after year.

　　Affected by US sanctions, the Iranian currency Rial has depreciated sharply in just a few years. Before the sanctions were restarted, more than 30,000 rials could be exchanged for 1 US dollar, but now it takes 30 Wan Li rials to exchange for 1 US dollar. The import and production costs of Iranian goods have increased significantly, and the shortage of materials has led to soaring prices and difficult people’s livelihood. Since 2018, the overall price in Iran has increased by about 85%, and food prices have doubled. Many Iranian families can’t make ends meet, and their lives are very tight. During the Chinese New Year, many Iranian children can’t put on new clothes, and many housewives have to think about buying a piece of meat for half a day.

　　The pain of people’s livelihood has caused Iranians to pay close attention to the Iranian nuclear talks and look forward to the early lifting of sanctions. However, the indirect negotiations between Iran and the United States on the Iranian nuclear deal’s resumption of performance have been going on for nearly a year and a half, with ups and downs in the middle, and no results have been achieved so far. The current U.S. government said one thing and did another. Although it verbally expressed its willingness to return to the Iranian nuclear deal, it inherited the previous government’s policy of "extreme pressure" on Iraq, and even during the negotiations, it continued to raise the threat tone and increase the sanctions against Iraq.

　　The current American government’s words and deeds are different, which has deepened the Iranian society’s cognition that "the United States cannot be trusted." Leahy said that if Americans want to reach an agreement, "why should they impose new sanctions on Iran during the negotiation?" Because the United States reneges on its word and has a bad track record, Iran is now very cautious in negotiations. The Iranian side has repeatedly asked the US to make a guarantee that it will not violate the contract again. Mohammad Marandi, consultant of the Iranian negotiating team, made it clear that Iran believes that corresponding provisions should be set, and if the United States breaches the contract again, it must pay the price.

　　Iranian society believes that "the United States cannot be trusted" is a silhouette of the increasing bankruptcy of American national credibility in the international arena. A number of polls show that the global influence of the United States is generally declining. In order to safeguard hegemonic self-interest, the United States has repeatedly broken the contract and "retired from the group" and provoked conflicts and confrontations. Although the United States often pretends to be so-called "democracy" and "human rights", it is hard to hide the evil consequences of its perverse actions on other countries and even the whole international community.

　　Fatty liver is becoming more and more common, and medical research suggests that it is closely related to diet. So, is there any way to "eat back" the "fat" liver that has been eaten?

　　"Yes!" Chen Zexiong, a famous Chinese medicine practitioner in Guangdong Province, pointed out that proper diet can really help the liver "slim down", which is also the treatment to eliminate the cause of fatty liver. However, people with "fat" liver should eat according to syndrome differentiation, and even cooking oil is particular. Experts also give three prescriptions: porridge, soup and tea to help patients with fatty liver to eat diet every day.

　　Fatty liver is mostly physical examination, and it is found that 30% to 40% is due to obesity.

　　Two days ago, an old acquaintance and classmate came to Sun Baoguo’s clinic. She was blessed and anxious. It turned out that the old classmate was found to have fatty liver in the physical examination of the unit. "I heard that it might be cirrhosis and liver cancer, which scared me to worry about what to eat and drink!" The old classmate said.

　　There are quite a few such cases. Most patients with fatty liver only find problems during physical examination.

　　This is because most of mild fatty liver has no obvious symptoms, or only a sense of fatigue, which is easy to be ignored. However, if it develops into moderate to severe fatty liver, there will be loss of appetite, fatigue, nausea, vomiting, weight loss, right hypochondriac or right upper abdominal pain. Moreover, if the treatment of simple fatty liver is neglected, it can develop into steatohepatitis and cirrhosis for a long time.

　　Fatty liver, as its name implies, is the excessive accumulation of fat in the liver. Medicine believes that it can be caused by many causes and diseases, mainly related to obesity, diabetes, alcoholism and so on. According to relevant literature reports, simple obesity accounts for 30%~40% of the causes of fatty liver, and many patients with fatty liver have high-fat and high-cholesterol diets, which suggests that the formation of fatty liver is closely related to diet, and diet may be the direct cause of disease in the general population.　　

　　Dietotherapy can eliminate the cause of fatty liver

　　Finding and eliminating the cause is the fundamental method to treat fatty liver, such as adjusting diet structure, losing weight, abstaining from alcohol and treating the primary disease.

　　Professor Chen Zexiong pointed out that a reasonable diet is of great significance to the prevention and treatment of fatty liver, especially for patients with simple fatty liver, most of them can be recovered through reasonable diet and exercise. Therefore, if you have fatty liver, don’t be afraid and worried. It is better to actively try diet therapy and "eat back" the problems you have eaten.

　　Then how to treat fatty liver?

　　Traditional Chinese medicine believes that this disease is caused by improper drinking and eating, invasion of human body by dampness, emotional disorder, or chronic illness and physical weakness, which leads to poor qi movement, and the combination of dampness, phlegm and blood stasis, which is blocked in the blood vessels and meridians of the liver. Therefore, regulating qi-flowing, eliminating phlegm-dampness, promoting blood circulation and removing blood stasis, and clearing the liver and gallbladder are the main methods for treating this disease in traditional Chinese medicine. The choice of daily diet for patients with fatty liver should also follow this principle. While paying attention to the color, smell and taste of food, try to choose foods that meet the actual needs of individuals.

　　List of foods to help the liver "lose weight"

　　Foods with fatty liver preventing and treating effects and nutrition metabolism improving effects;

　　Patients with fatty liver who are uncomfortable with the right hypochondriac rib (that is, the right chest from the armpit to the sternum) and easy to get angry can eat more vegetables, chrysanthemum, tomatoes, shepherd’s purse, etc., which can clear away heat and cool the liver;

　　Patients with bad breath, constipation and fatty liver who overeat greasy food can eat more vegetables and fruits rich in vitamins and cellulose, such as radish, bamboo shoots, wax gourd, loofah, celery, cucumber, water chestnut and hawthorn fruit, which can clear away heat, promote bowel movement and facilitate urination;

　　Fatty liver patients with physical weakness can choose low-fat and high-protein foods such as pork lean meat, pigeon meat, rabbit meat, beef lean meat, skim milk, soybean milk, etc., which can tonify liver and kidney, replenish qi and nourish blood.

　　Food unsuitable for patients with fatty liver:

　　Pig fat, goose, duck eggs, animal oil, animal viscera and animal brain have high fat content; Crab, crab roe, squid, cuttlefish, clam meat and anchovies are high in cholesterol, so it is advisable to eat less or not. Because sugar will turn into fat in the body, which will aggravate fatty liver, it is better to eat less high-sugar foods such as litchi, longan pulp, candied fruit, preserved fruit and sugar.

　　Selection of staple food and oil:

　　It is suggested that fatty liver patients should choose vegetable oils such as vegetable oil, sesame oil, cottonseed oil and peanut oil, because they contain more unsaturated fatty acids and have the effect of lowering blood cholesterol. The staple food can be low-sugar foods such as corn flour, buckwheat flour, oat flour, bean flour and other products. These foods are coarse grains, which can reduce qi and broaden the intestines and cleanse the greasy stomach.

　　One porridge, one soup and one tea are most suitable for liver "fat"

　　Patients with fatty liver in daily life can also choose medicated diet for conditioning:

　　Hawthorn Carassius auratus soup: Take 30g of raw hawthorn, one crucian carp, 10g of immature bitter orange, appropriate amount of ginger and water, and drink the soup after cooking. Regular administration of this decoction can promote blood circulation and qi circulation, and has a certain effect on hypochondriac swelling pain or acupuncture-like pain, or hepatomegaly and purple tongue.

　　Pueraria flower tea: 15g of Pueraria flower, 10g of Salvia miltiorrhiza, 4-5 tablets of Ilex kudingcha, appropriate amount of water, boiling and simmering for 30min, and taking the juice as tea. Used for long-term alcoholism and mutual stagnation of dampness and blood stasis.

　　Codonopsis pilosula millet porridge: 10 grams of Codonopsis pilosula, 10 grams of Poria cocos, 20 grams of lentils, boiled for 30 minutes with appropriate amount of water, added with 100 grams of millet, and cooked with slow fire. For people with weak temper, such as listlessness, pale complexion and loss of appetite, this porridge can be taken frequently.

　　Special reminder that dietotherapy doesn’t work, hurry up with medication.

　　Experts pointed out that while adjusting the diet structure, patients with fatty liver should also take appropriate exercise to keep their mood comfortable, which is helpful for the treatment of fatty liver.

　　Special reminder, for those who have the primary disease or the above methods can not be effective, they must go to a regular hospital to find a specialist to deal with it, and cooperate with drug treatment to avoid delaying the illness.
