Q&A on China’s economy in the two sessions: What do you think of China’s price movement? -The second question and answer of China economy in the two sessions.

    Xinhua News Agency, Beijing, March 6th Question: How do you view China’s price movement? -The second question and answer of China economy in the two sessions.

    Xinhua News Agency reporter Wei Yukun and Wu Yu

    Since last year, China’s price increase has been running at a low level, which has aroused some people’s worries about China’s deflation. How to treat China’s price movement situation? Is China’s economy really in deflation?

    During the two sessions of the National People’s Congress, the reporter interviewed many NPC deputies, Chinese People’s Political Consultative Conference members and authoritative experts to analyze this issue and respond to external concerns.

   Does low prices mean deflation?

    Since October last year, the consumer price index (CPI) has been declining year-on-year, and it will drop by 0.8% in January 2024. At the same time, the national producer price index (PPI) continued to decline.

    The low price has caused some worries about whether China’s economy will fall into deflation.

    To judge whether we are caught in deflation, we must first clarify the concept. Generally speaking, in economics, deflation mainly refers to the continuous negative growth of prices and the downward trend of money supply, which is usually accompanied by economic recession. This depends not only on the "shape" of price operation, but also on the "state" of money supply and the "potential" of economic development.

    -Price operation: generally low, maintaining a moderate upward trend.

    According to the government work report submitted for deliberation on the 5th, the consumer price of China residents rose by 0.2% in 2023. This data is in stark contrast to the high inflation in major developed economies.

    Jin Li, member of Chinese People’s Political Consultative Conference and vice president of south university of science and technology of china, said that last year, the core CPI excluding volatile food and energy prices rose by 0.7% year-on-year, indicating that the supply and demand of industrial consumer goods and service consumption in China were generally stable. The year-on-year decline of PPI also decreased by 5.4% from the highest in June last year to 2.5% in January 2024.

    Since last year, China’s monthly price level has always fluctuated moderately within a reasonable range. In January 2024, CPI rose by 0.3% month-on-month, which has been rising for two consecutive months.

    -Money supply: the total amount is moderate and the rhythm is stable.

    By the end of January 2024, the balance of broad money (M2) in China was 297.63 trillion yuan, up 8.7% year-on-year. Under the background of high base in the same period last year, it maintained a reasonable growth rate.

    The scale of social financing is a comprehensive indicator of financial support for the real economy. In January, the scale of social financing in China increased by 6.5 trillion yuan, 506.1 billion yuan more than the same period of last year.

    -economic development: the overall recovery is improving.

    In 2023, China’s economy generally rebounded, with a GDP growth rate of 5.2%, which was faster than the average growth rate of 4.5% in the three years of the epidemic, and also significantly faster than the economic growth rates of 2.5% in the United States, 0.5% in the euro zone and 1.9% in Japan, making it an important engine of global economic growth.

    Since 2024, China’s manufacturing purchasing managers index, SME development index and other indicators have rebounded from last December. The International Monetary Fund (IMF) recently raised its forecast for China’s economic growth this year and cast a "vote of confidence" for China’s economy.

    "Deflation is often the result of long-term accumulation of structural problems in economic operation. Judging deflation should not only focus on one or two price indicators." Huang Maoxing, deputy to the National People’s Congress and vice president of Fujian Academy of Social Sciences, said that on the whole, there is no deflation in China, let alone deflation spillover, and the so-called "economic deflation in China" is totally a false proposition.

    Not long ago, ING reported that the discussion about deflation in China was exaggerated by the outside world. In January, the overall CPI and core CPI in China both rose month-on-month, reflecting that China has not fallen into a "deflation spiral".

    "We don’t expect an overall deflationary trend in China." Gita Gopinath, First Vice President of IMF, said not long ago.

   What are the reasons for the low price increase?

    Prices are related to economic operation and affect people’s lives. At present, the low price increase in China is the result of multiple factors.

    "After the smooth transition of epidemic prevention and control, domestic production has accelerated recovery, logistics has remained smooth, and product supply is sufficient. However, demand is constrained by factors such as expected instability and income distribution differentiation, and recovery will take some time." Xu Guangjian, vice president of China Price Association, said that the time difference between supply and demand recovery is the main factor for the lower prices.

    Commissioner Jin Li said that in 2022, due to the Ukrainian crisis, food and energy prices were higher, which made the CPI increase in 2023 relatively low. In addition, the price of pork occupies a high weight in China CPI. Due to the abundant supply of live pigs and pork and the sluggish consumption of superimposed pork, the domestic pig price continues to fall, which lowers the CPI increase.

    Input factors also have an impact on China’s prices. After the epidemic, in order to cope with high inflation, major central banks in the United States and Europe quickly and intensively adjusted their monetary policies, and the year-on-year increase of CPI in the United States and Europe has dropped from the previous high of about 10% to the current 3%. "The inflation level in developed economies has fallen faster than expected, which has an impact on the price level in China." Pan Gongsheng, governor of the People’s Bank of China, said.

    Xing Ziqiang, chief economist of Morgan Stanley in China, said that China’s lower prices may have a positive spillover effect on global trade goods prices, which will help alleviate the "sequela" of unconventional stimulus policies adopted by some economies in response to high inflation.

    The experts interviewed agreed that the factors that caused the current low price operation in China are mainly phased, cyclical and seasonal, not trending, and its influence should not be exaggerated.

    This year’s government work report sets the expected target of annual consumer price increase at around 3%. According to the plan report submitted for review on the 5th, the main consideration for setting this goal is to comprehensively analyze the hikes of price changes in 2023 and the new price increase factors in 2024. It is expected that consumer prices will rise moderately in 2024.

    "This expected goal is consistent with last year’s expected goal, in line with the overall trend of domestic price stabilization and recovery, and leaves some room for strengthening macro-policy regulation and deepening price reform." Yu Miaojie, deputy to the National People’s Congress and president of Liaoning University, said.

   How to prevent the risk of deflation?

    Delegates and experts interviewed said that although the low domestic price operation is temporary, we should be alert to and guard against deflation risks, and actively and effectively solve problems such as insufficient effective domestic demand and overcapacity in some industries.

    -Strengthening macro-policy control.

    The government work report pointed out that the liquidity should be kept reasonable and sufficient, and the scale of social financing and money supply should match the expected goals of economic growth and price level.

    "Maintaining a reasonable and sufficient liquidity is an effective measure to prevent deflation risks. This year’s government work has clearly promoted the steady decline of comprehensive social financing costs, which is expected to further stimulate the effective demand of the real economy and enhance residents’ willingness to consume and invest. " Ceng Gang, director of Shanghai Finance and Development Laboratory, said.

    A proactive fiscal policy should moderately increase efforts, improve quality and increase efficiency; A prudent monetary policy should be flexible, moderate, accurate and effective; Incorporate non-economic policies into the consistency assessment of macro-policy orientation … A number of arrangements in this year’s government work report have strengthened policy co-ordination to ensure that efforts are made in the same direction and joint efforts are formed.

    -Promote the formation of a virtuous circle in which consumption and investment promote each other.

    Han Baojiang, a member of Chinese People’s Political Consultative Conference and a professor at the Central Party School (National School of Administration), said that at present, the key to preventing deflation risks is to expand domestic demand, release the potential vitality of the super-large-scale market, and enhance the ability and confidence to resist external imported risks.

    When deploying this year’s tasks, the government work report pointed out that the implementation of the strategy of expanding domestic demand should be organically combined with deepening the structural reform on the supply side, so as to better coordinate consumption and investment and enhance the pulling effect on economic growth.

    Optimize the consumption environment, carry out the "consumption promotion year" activity and implement the "rest assured consumption action"; Deepen the cultivation and construction of international consumption center cities; Promote the construction of additional national debt projects with high quality; We will implement a new cooperation mechanism between the government and social capital, and encourage private capital to participate in major project construction … The government work report and the plan report will focus on expanding domestic demand this year.

    "With the implementation of a series of policies to expand domestic demand, giving full play to the key role of investment in optimizing the supply structure and promoting the upgrading of domestic consumption structure, the domestic economic cycle will be further smooth." Qu Yongyi, member of Chinese People’s Political Consultative Conference and secretary of the Party Committee of the Institute of Industrial Economics of the Chinese Academy of Social Sciences, said.

    Ayhan Gauss, deputy chief economist and director of the forecasting bureau of the World Bank, said that a series of policies adopted by China at present are very correct, which can boost consumer confidence and consumption in the short term, and enhance the long-term economic growth potential through firm reforms.

Ling Yunguang: Building a platform for technology and products, multi-industry empowerment and intelligent manufacturing

  China Securities Network News (Wang Luo) started from the printing industry. Lingyun Guang has been deeply involved in the industrial machine vision industry for 20 years, and has expanded its applications to consumer electronics, new displays, new energy and other fields. Head enterprises in industries such as Apple, Huawei, Xiaomi, Foxconn, BOE and () are all important customers of Lingyun Guang.

  On June 15th, Ling Yunguang (stock code: 688400) officially launched the inquiry offering, and will soon land in science and technology innovation board. The science and technology innovation board listing, Lingyun Guang plans to raise 1.5 billion yuan, and the fundraising direction is centered on the company’s vision planning. From industrial manufacturing to industrial intelligent manufacturing, machine vision is promising. The company will increase investment in technology research and development, continuously improve its platform-based capabilities, empower intelligent manufacturing, and help more industries achieve automation and intelligent development. The company’s development vision is to implant "eyes" and "brains" into machines and become a global leader in the fields of visual artificial intelligence and photoelectric information.

  From agency to self-research, mastering the underlying core technology

  According to the prospectus, Ling Yunguang was established in 2002, and started from the banknote printing industry, and carried out independent research and development through projects such as online detection of RMB gravure printing and large sheet detection; On the other hand, the agency business of foreign high-end visual devices is carried out. Since 2006, the company has successively entered the fields of printing and packaging, new display and consumer electronics, and further improved its independent research and development capabilities. At present, it has the research and development capabilities of advanced imaging, intelligent algorithms, intelligent software and automatic precision control, and independently developed core devices such as industrial cameras and light sources, which are applied to many industries.

  The domestic machine vision started in the late 1990s. When Ling Yunguang entered this field 20 years ago, the domestic development and application were basically blank. The company started from scratch and gradually embarked on the road of independent research and development in the field of machine vision.

  Ling Yunguang attached great importance to self-research of core technologies at the early stage of business development. During the period from 2002 to 2006, the company initially built a 100-person team with independent research and development capabilities of optical, mechanical, electrical, computing and software technologies, and started the research and development of independent software algorithms of VisionWARE. The technical accumulation in this period has created an insurmountable moat for the company’s competitors in a short period of time. Now the machine VisionWARE algorithm platform independently developed by the company has been iterated to version 5.0. Ling Yunguang is the first machine vision manufacturer in China to launch a purely independent bottom-level core algorithm library. The investment cycle of the bottom-level algorithm is quite long. It takes a lot of time and experience to optimize the core algorithm from the bottom, which makes it ahead of competitors in the same industry for about three to five years.

  In addition, Ling Yunguang’s AI algorithm development based on deep learning, machine learning and knowledge map has also been at the forefront of the industry, forming an independent F.Brain intelligent algorithm platform, supporting factory-side and edge intelligence through edge computing, and supporting factory cloud intelligence through big data cloud computing technology. From the application point of view, the machine vision +AI technology is deeply combined to support industrial scenes.

  It is understood that the algorithm library of the machine vision industry consists of open source vision algorithm libraries such as OpenCV, and third-party commercial payment algorithm libraries such as Vision Pro (cognex, USA), Halcon (German MVTec) and VisionWare (Ling Yunguang). Due to the long development cycle and large investment of algorithm library, companies in the industry usually develop their own application algorithms based on open source algorithm library, or independently develop and integrate with third parties, and few companies develop the underlying algorithms completely independently.

  In addition to algorithms, Lingyun Guang has always been at the forefront of optical imaging technology, and has independently developed a series of visual core devices such as smart cameras and high-brightness special light sources. It has more than 70 patents in the optical field, and many solutions are the first to benchmark international and domestic machine vision friends, creating a brighter industrial "eye" competitiveness. At the same time, by investing in domestic CMOS sensor design company Changguang Chenxin and industrial lens professional company Hunan Changdao Optoelectronics, we will optimize the allocation of core resources and lay out the localization and autonomy of core technologies.

  Form platform capability from system to equipment

  After all, the banknote printing industry belongs to a special industry. After 2006, Ling Yunguang gradually expanded its business to printing and packaging, display screens, consumer electronics and other industries, and further integrated its research and development capabilities into platform-based capabilities of products and technologies, thus effectively supporting the company to achieve cross-industry development. In addition, the company began to expand its automation capability in 2016, and it took three years to gradually build automatic control technologies such as automatic assembly line and multi-axis precision manipulator.

  Up to now, Lingyun Guang has four technical platforms, including advanced imaging, intelligent algorithm, intelligent software and intelligent automation, and comprehensive overall scheme design capability. It has 418 domestic patents and 208 software copyrights, which supports the company’s rapid expansion of downstream industries from printing to other fields, such as consumer electronics and new energy, and is also a technical base to support the company’s continuous leap-forward development in the future.

  According to Ling Yunguang’s prospectus, up to now, the company has developed diversified intelligent visual equipment and innovative process solutions based on independent research and development of visual algorithms and AI algorithms for new display, consumer electronics, printing and packaging, new energy and other fields. Specific to the display field, the new display intelligent vision equipment products provided by Ling Yunguang can realize automatic and semi-automatic optical detection of small screen defects in TFT-LCD/OLED, covering the Cell process section and module process section, and support lighting detection when the screen is powered on and appearance detection when it is not powered on. The detection efficiency of the LCD lighting quality detector provided by it is more than 3 times that of manual work, which solves the problem of 2% low contrast stain defect detection, approaches the limit of human eyes, realizes high dynamic range detection, and has been popularized and applied in hundreds of sets in the industry.

  Entering Apple’s industrial chain is a key milestone for Ling Yunguang, and it is also the inevitable result of technical capacity building. Five years ago, the company broke the situation that the high-end market of consumer electronic vision inspection was monopolized by foreign manufacturers such as cognex and Kearns for a long time, and became the Preferred Supplier in the field of machine vision certified by Apple, and began to provide configurable vision systems in batches.

  "Hand", "Eye" and "Brain" cooperate to empower intelligent industrial production.

  If configurable vision system products, such as machine vision algorithm platform developed by Ling Yunguang, can equip industrial machines with eyes and brains, then intelligent vision equipment is to implant muscles and limbs controlled by brains into the machines, thus realizing the precise control and execution of detection and production technology, and finally forming an intelligent production robot with the cooperation of hands, eyes and brains.

  As the largest manufacturing country in the world, the penetration rate of domestic machine vision application is low, and there is still much room for growth, especially the aging population and the increase in labor costs, which also bring great demand to the machine vision industry.

  From the demand of downstream customers, the epidemic situation in COVID-19 is complicated in recent years. Instead of reducing the budget for technology investment, downstream manufacturers have been further forced by the epidemic to strengthen their investment in industrial automation, digitalization and intelligence, and the cost reduction effect is very remarkable. In the future, the demand of downstream manufacturers for automation and intelligence is rigid and inevitable.

  China market has become one of the fastest growing markets in the global machine vision market. According to the statistics of China Machine Vision Industry Alliance, the sales of machine vision industry in China increased from 10.18 billion yuan in 2018 to 14.42 billion yuan in 2020, with a compound growth rate of 19.02%. Thanks to the promotion of manufacturing automation and other factors, it is estimated that the sales of machine vision industry in China will increase at a compound growth rate of 27.15% from 2020 to 2023, and the sales will reach 29.6 billion yuan by 2023.

  Under such opportunities, Lingyun Guang will continue to promote technological innovation in advanced optical imaging, software and algorithms, automation and other fields, and actively explore new application fields of industrial machine vision. At present, Ling Yunguang’s machine vision +AI products and services have achieved a high market share in consumer electronics, display panels, printing and packaging applications. According to the statistics of China Machine Vision Industry Alliance, in 2020, among the enterprises participating in the statistics (enterprises within the alliance), Lingyun Guang ranked first in the sales of machine vision industry in China.

  According to the disclosure in the prospectus, the company is expanding its business to the field of new energy battery diaphragm detection, and has cooperated with customers such as Contemporary Amperex Technology Co., Limited. Focusing on the field of industrial manufacturing for 20 years, Lingyun Guang is expected to become the leader of industrial artificial intelligence, truly helping factories to improve quality, increase efficiency, reduce costs and reduce storage.

Inventory of customs clearance mode of cross-border import e-commerce

Inventory of customs clearance mode of cross-border import e-commerce

At present, the customs clearance modes of cross-border e-commerce import business mainly include: express customs clearance, goods collection customs clearance and stock clearance.

What are the customs clearance modes for cross-border e-commerce?

(A) cross-border e-commerce import customs clearance mode-express customs clearance

After the order is confirmed, foreign suppliers will mail the goods directly from overseas to consumers through international express delivery. No customs documents.

Advantages: flexible, delivery only when there is business, no need to stock up in advance;

Disadvantages: When mixed with other express mail, the logistics clearance efficiency is low, and the cost will rise rapidly when the volume is large;

Suitable: the stage of less business volume and occasional sporadic orders.

(B) Cross-border e-commerce import customs clearance mode-goods collection customs clearance (orders first, then delivery)

Merchants package a number of sold goods in a unified way and transport them to domestic bonded warehouses through international logistics. E-commerce enterprises go through customs clearance procedures for each product. After being checked and released by the customs, e-commerce enterprises entrust domestic express delivery to consumers. Each order is accompanied by customs documents.

Advantages: flexibility, no need to prepare goods in advance, higher logistics clearance efficiency and lower overall logistics cost compared with express mail clearance.

Disadvantages: the packaging operation needs to be completed overseas, and the overseas operation cost is high, and the delivery from overseas takes a little longer.

Suitable for: at the stage of rapid growth of business volume, there are many orders every week. (3) Customs clearance mode of cross-border e-commerce import-stocking customs clearance (stocking first, then ordering)

Merchants stock overseas goods in batches to bonded warehouses under customs supervision. After consumers place orders, e-commerce enterprises go through customs clearance procedures for each product according to the orders, complete the veneer sheet and packaging in the bonded warehouses, and after being checked and released by the customs, e-commerce enterprises entrust domestic express delivery to consumers. Each order is accompanied by customs documents.

Advantages: bulk stocking to bonded warehouse in advance, the lowest international logistics cost, immediate delivery from bonded warehouse after orders are placed, the highest customs clearance efficiency, timely response to after-sales service requirements and the best user experience.

Disadvantages: the use of bonded warehouses has storage costs, and stocking will occupy funds.

Application: in the stage of large business scale and stable business volume. Purchase cost can be reduced by ordering in large quantities or in advance, and the international logistics cost can be reduced by gradually transitioning from air transportation to sea transportation, or the problem of capital occupation caused by stocking can be solved by pledge supervision financing.

I successfully developed my own technology to stop the plane from running off the runway and break the US monopoly.

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.

Here comes Gemini, Google’s strongest model! Really multi-modal, pouring all resources and supporting Chinese, GPT4 is no longer unique.

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.

However, this is, after all, an AI pioneer who contributed to Transformer’s pioneering masterpiece Attention is all you need and the landmark artificial intelligence program AlphaGo, and inspired the subsequent development of many large models including ChatGPT. No matter from the technical genes, training data, capital and infrastructure, it should have one of the best strengths.

The release of Gemini is regarded by Google as the most critical technological innovation in the past decade. Can it make Google rally, beat OpenAI and regain the throne of the big model stadium?

Will the AI competition pattern be reshaped after Genmini Ultra comes out next year?

And, has everyone tried the new Google Bard? How do you feel?

Guide: western medicine treatment of herpes zoster

Click on "Huanghuai nurse" above to follow.

guide language

The treatment scheme of herpes zoster can be roughly divided into traditional Chinese medicine therapy and western medicine therapy. Today, we will learn the western medicine therapy recommended by the guide.

Therapeutic goal of herpes zoster

Relieve acute pain; Shorten the duration of skin lesions; Prevent the spread of skin lesions; Prevent or reduce complications.

First, antiviral drugs

Commonly used drugs in clinical treatment of herpes zoster can effectively shorten the course of disease, accelerate the healing of rash, reduce the formation of new rash and reduce the spread of virus to internal organs. It should be used within 72 hours after the eruption, so as to quickly reach and maintain the effective concentration and obtain the best therapeutic effect. At present, the approved systemic antiviral drugs include acyclovir, valaciclovir, famciclovir, bromovudine and foscarnet sodium.

acyclovir

Function characteristics:

Acyclovir triphosphate is produced by phosphorylation of viral thymidine kinase in infected cells, which can inhibit viral DNA polymerase and stop the extension of viral DNA chain.

  Usage:

(1) Oral administration: 400-800 mg/time, 5 times/day, for 7 days;

(2) Intravenous drip: 5 ~ 10 mg/kg for patients with immune impairment or serious nervous system diseases, once every 8 hours, with a course of 7 days. 

Precautions:

Patients should drink plenty of water during the administration of acyclovir to prevent acyclovir from precipitating in renal tubules and damaging renal function.

Valaciclovir

Function characteristics:

The prodrug of acyclovir is quickly absorbed by oral administration and quickly converted into acyclovir in gastrointestinal tract and liver, and its bioavailability is 3~5 times that of acyclovir.

  Usage:

Oral administration: 300 ~ 1000 mg/time, 3 times/day, for 7 days.

Fanciclovir

Function characteristics:

The prodrug of penciclovir is rapidly converted into penciclovir after oral administration, and maintains a long half-life in cells. The mechanism of action is the same as that of acyclovir, the bioavailability is higher than that of acyclovir, and the frequency and dosage of administration are lower than that of acyclovir.

  Usage:

Oral administration: 250 ~ 500mg/time, 3 times/day, for 7 days.

brivudine tablets

Function characteristics:

The antiviral effect is highly selective, and the process of inhibiting virus replication is only carried out in virus-infected cells. 

Usage:

Oral administration: 125mg//day, l times/day, for 7 days.

Sodium foscarnet

Function characteristics:

Blocking the phosphate binding site of viral DNA polymerase in a non-competitive way, thus showing antiviral activity.

  Usage:

Intravenous drip: 40 mg/kg each time, once every 8 hours.

Note meaning 

Patients with renal insufficiency should reduce the dosage accordingly;

If renal function continues to decline, acyclovir should be stopped immediately and famciclovir or other antiviral drugs should be used to continue treatment;

For patients suspected of renal insufficiency, creatinine level should be detected before initial administration (creatinine level is not required for bromovudine).

Second, analgesics

Mild to moderate pain:Acetaminophen and tramadol can be selected; 

Moderate and severe pain:

1. Opioid drugs, such as morphine or oxycodone;

2. Drugs for the treatment of neuropathic pain, such as calcium channel regulator gabapentin and pregabalin, in addition to amitriptyline and 5% lidocaine patch. Severe acute pain during herpes zoster is a risk factor for post-herpetic neuralgia (PHN). Combined with calcium channel regulator can not only effectively relieve pain, but also reduce the occurrence of PHN. Studies have shown that early use of pregabalin can significantly reduce the pain score of herpes zoster, especially within 7 days of herpes occurrence, which can significantly reduce the incidence of PHN. The pain of elderly patients with herpes zoster is more common and severe, which seriously affects all aspects of life, such as anxiety, disorder and inability to work or live normally. Studies have shown that pregabalin combined with oxycodone can not only further reduce the incidence of PHN, but also improve the daily activities and sleep of patients and improve their quality of life.

Third, glucocorticoid

At present, there is still controversy about whether to use glucocorticoid to treat herpes zoster.

It is generally believed that systematic application of glucocorticoid in the early stage of acute onset of herpes zoster and gradual decrease can inhibit the inflammatory process, shorten the duration of acute pain and the healing time of skin lesions, but it is ineffective for the pain with PHN. 

Recommended dose:The initial dosage of prednisone is 30~40 mg//day, which is taken orally and gradually reduced, and the course of treatment is 1~2 weeks.

 Fourth, neurotrophic drugs

It is also helpful to relieve neuroinflammation and neuralgia. Commonly used drugs include mecobalamin, vitamin B1 and vitamin B12, etc., which are taken orally or injected intramuscularly.

Five, topical drugs

Mainly dry and anti-inflammatory. 

Blister fluid is not broken:Calamine lotion, acyclovir cream or penciclovir cream can be used externally. 

After herpes is broken:

3% boric acid solution wet compress;

1: 5000 furacilin solution wet compress;

0.5% neomycin ointment for external use;

2% mupirocin ointment. 

Ophthalmic herpes:3% Acyclovir Eye Ointment and Iodine Eye Drops for External Use.

  Below the video, Russian netizens gave many conjectures about why dead birds fell from the sky. Some people blame it on natural phenomena, such as a strong wind or an accidental collision between two birds. Others think that fireworks and exhaust gas from factories may cause a large number of deaths, and some even say that it is related to 5G equipment, although this technology has not yet entered Russia.

  "At the beginning of the nuclear disaster TV series Chernobyl, all the birds died." A comment with the highest praise linked the incident to the American HBO hit drama. The animal medical department of Saratov State is currently investigating this incident, which some people think may be related to bird flu. (Overseas Network Zhang Qi)

China’s first intelligent blind road application scenario started.

A few days ago, more than 40 people with severe visual impairment came to Hezhuang Cultural and Sports Center in Qiantang District, incarnating as "raiders of the lost ark", and launched an interesting "treasure hunt" in the first application scene of wisdom blind road in China.

At the scene, after the simple training of the staff of the R&D unit, the participants easily mastered the use of the wisdom cane. At the beginning of the activity, each participant got the wisdom cane distributed by the staff. After quickly connecting to the related small programs on their mobile phones, they turned into "raiders of the lost ark" on the designated route.

The treasure hunt route is nearly 100 meters long. Participants will pass through barrier-free ramps, barrier-free elevators and barrier-free doors, and go upstairs, go straight and turn under the guidance of the wisdom blind road. After reaching the finish line, participants can receive corresponding rewards by virtue of the "treasure list" on their mobile phones.

After the experience, visually impaired people praised the innovation of electronic blind roads-

"Enter the end point accurately on the mobile phone and follow the guide. There are voice prompts all the way, which is very clear. When I was looking for treasure, I was particularly happy when I heard the gold coin ringing. " Participant Shen Haidan said.

"Electronic blind roads are more accurate, more secure, more convenient and more humanized than traditional blind roads. The prompts of’ Go Forward’,’ Turn Left’ and’ Turn Right’ make us feel that the service is warm and caring. At present, I feel that there is a slight delay in matching, and I hope I can continue to improve. " Participant Zheng Yan said.

"Electronic blind roads can be located in bathrooms, conference rooms, offices and other places in buildings, which is more suitable for blind friends to travel, and I hope it can be promoted!" Participant Jiang Longxiang said.

The first "Treasure Hunt" of the "Qiantang Cup" was directed by Hangzhou Blind Association, and jointly sponsored by Qiantang Disabled Persons’ Federation and Hezhuang Sub-district Office.

In recent years, Hangzhou Disabled Persons’ Federation and Qiantang Disabled Persons’ Federation have devoted themselves to building the Hezhuang Cultural and Sports Center in Qiantang District as a model of the national advanced barrier-free cultural and sports center. After successfully building the first barrier-free swimming pool in China, they also focused on information barrier-free construction, and created the first intelligent blind road application scene in China.

Zhao Cheng, chairman of Hangzhou Blind Association, introduced that the application scene of the intelligent blind road compensates for the lack of vision through sound, and stimulates the enthusiasm of visually impaired people through technology, which can help them better participate in the experience and integrate into society. "I hope that with the joint efforts of all walks of life in the future, severely visually impaired people can also go out of their homes more conveniently, set foot on urban blind roads, enjoy urban public transportation and enjoy work and life without obstacles."

Alipay responded to promote the optimization of payment service: the amount has been raised, and multi-language and one-code communication will be launched in the near future.

On March 7th, the General Office of the State Council issued the Opinions on Further Optimizing Payment Services and Improving Payment Convenience, which mentioned that the needs of the elderly, foreigners coming to China and other groups should be fully considered, and the aging and internationalization service arrangements should be made.

The relevant person in charge of the People’s Bank of China said that the Opinions put forward six major tasks:

First, effectively improve the acceptance environment of bank cards to meet the needs of the elderly, foreign visitors to China and other groups of "food, housing, transportation, travel, shopping, entertainment, medical care" and other scenarios.

Second, adhere to the positioning of cash, continuously optimize the cash use environment, and continuously improve the level of foreign currency exchange and cash services.

The third is to further enhance the convenience of mobile payment, encourage banks, payment institutions and clearing institutions to cooperate, and make good service arrangements such as aging and internationalization.

The fourth is to better protect consumers’ right to pay. Large business districts, tourist attractions, entertainment venues, hotel accommodation and other key places above designated size must support diversified payment methods such as mobile payment, bank cards and cash.

Fifth, optimize the account opening service process, rationally implement the classified and hierarchical management of accounts, keep a close eye on key areas, key outlets and key business links, improve supporting measures for account opening, and continuously improve the service level of accounts.

Sixth, comprehensively use various ways and channels to continuously strengthen the promotion of payment services.

On the evening of March 7th, Alipay said that it was actively responding to the relevant decision-making arrangements of the CPC Central Committee and the State Council, and with the support and guidance of the People’s Bank of China and the Foreign Exchange Bureau, it was solidly promoting the implementation of various measures to continuously optimize the payment services for the elderly and foreigners coming to China. It is reported that Alipay has completed the promotion and optimization of the transaction limit for foreigners, with the single transaction limit raised from $1,000 to $5,000 and the annual transaction limit raised from $10,000 to $50,000. In addition, new services such as multi-language translation and overseas wallet ride code "One Code Pass" will be launched one after another.

Tenpay said that with the support and guidance of the People’s Bank of China and the foreign exchange bureau, Tenpay has implemented a number of measures around "aging and upgrading". In terms of facilitating the payment of foreign nationals in China, simplification measures have continued to land. Since the comprehensive upgrade in July last year, the transaction volume of WeChat payment foreign cards has continued to grow. Compared with the opening of only some pilot merchants, the highest number of transactions in a single day in February 2024 increased nearly five times.
