Since the American government announced its National Nanotechnology Plan (NNI) to the whole world in March 2000, nanotechnology, a little-known technical vocabulary in the 20th century, has become a high-frequency word when the media reported on scientific and technological plans and progress. Even some lawless elements use it to deceive some people who like "technology fashion".
　　
　　Nanotechnology refers to:
　　Nanotechnology will trigger a new industrial revolution in the 21st century. Undoubtedly, the birth and development of nanotechnology has opened up a new level of human understanding of the world, and extended human ability to transform nature directly to atoms and molecules, marking a new era of human science and technology. Scientists pointed out that nanotechnology will have a far-reaching impact on the development of productive forces, and it is possible to fundamentally solve a series of problems currently faced by mankind, such as extremely important problems such as environment, food and energy. Nanotechnology will be one of the leading technologies in the 21st century. The science and technology adviser of the President of the United States also spoke highly of the importance of nanotechnology to the future development of knowledge economy. He believes that the benefits brought by the development of nanotechnology to social development, economic revitalization and the improvement of people’s quality of life will be incomparable to general technology, and the wealth created by nanotechnology in the 21 ST century is also incalculable. The influence and penetration of nanotechnology in various fields may exceed that of computers. (Olympic Science and Technology Website)

On May 7 th, MediaTek just announced the launch of a technically enhanced version of the Dimensity 1000 series-Dimensity 1000+ chip, based on the performance of flagship platform Dimensity 1000 series, also adopts 7nm process technology.On this basis, Dimensity 1000+ aims at5G power consumption, screen refresh rate, gaming experience, and display quality.All four aspects have been upgraded accordingly.

"As the flagship 5G SoC, MediaTek Dimensity 1000 Series not only has powerful performance, but also comprehensively optimizes the user experience of 5G smartphones through technology upgrades." Dr. Li Yanji, deputy general manager of MediaTek Wireless Communication Division, said that Dimensity 1000+ based on’s 5G, power saving, screen, games and video technologies in MediaTek has further brought better flagship 5G experience to high-end users.

It is reported that,Dimensity 1000+ chip will be launched in iQOO, a sub-brand of vivo, and will be released in a short time.

▲ Li Junnan, Director of Technical Planning, MediaTek Wireless Communications Division

In the media interview after the meeting, Dr. Li Yanji, deputy general manager of MediaTek Wireless Communication Division, mentioned that although the novel coronavirus epidemic this year had an impact on the production capacity and sales of mobile phones in the first quarter, MediaTek’s judgment on the entire domestic 5G market would not change much. At present, the planning of 5G products in MediaTek is still in progress.

Dimensity 1000+ adopts MediaTek 5G UltraSave power-saving technology developed by MediaTek, which has the functions of C-DRX energy-saving management and BWP dynamic bandwidth regulation, and can dynamically adjust the working mode according to the network environment and data transmission, such as power supply configuration and working frequency.

Li Junnan, technical planning director of MediaTek Wireless Communication Division, mentioned that this technology can further reduce the 5G power consumption of terminal equipment, and at the same time, compared with competitors of the same level of friends, the average 5G power consumption of Dimensity 1000+ is reduced by 48%.

In addition, Dimensity 1000+ also supports 5G dual-carrier aggregation aggregation and 5G+5G dual card dual standby.

In terms of screen, Dimensity 1000+ supports a screen refresh rate of 144Hz, and the screen presented per second is 2.4 times that of the ordinary 60Hz screen. Li Junnan said that the screen refresh rate of 144Hz can greatly reduce the smear and jamming problems in applications such as high-frame videos and games.

In terms of game optimization, Dimensity 1000+ is equipped with MediaTek HyperEngine 2.0 game optimization engine, which optimizes the intelligent load control engine, network optimization engine and control optimization engine on the basis of the previous generation technology, further enhancing the experience of game transition, network and peripheral control.

1. Intelligent load control engine: game fast transition.

This technology can accelerate the rapid transition of the game, intelligently adjust CPU, GPU and memory resources, and realize low-power operation while taking into account the full frame of the picture.

Compared with the flagship of Youshang, Dimensity 1000+ can reduce the power consumption of playing games under 5G by up to 32%.

2, network optimization engine: game/video call uninterrupted network.

This technology allows users to keep the connection between games and video calls stable and smooth when they encounter incoming calls while playing games or video calls.

In addition, the network optimization engine also supports intelligent 5G/4G switching, which can intelligently detect users’ network throughput and bandwidth requirements, select the best network transmission, and reduce the average power consumption by up to 60%.

3, control optimization engine: Bluetooth /Wi-Fi low delay anti-interference.

HyperEngine 2.0′ s control optimization engine technology optimizes the Bluetooth transmission of devices, which can reduce the delay of game sound, picture and control synchronization.

At the same time, the engine also has Wi-Fi/BT anti-jamming technology, which realizes the parallel transmission of Bluetooth and Wi-Fi, further reducing the delay of Wi-Fi network, and the longest delay is reduced by 25%.

4. MiraVision image quality engine: real-time frame-by-frame tuning of 4K video.

The chip-level MiraVision image quality engine is based on the independent AI processor APU3.0, which mainly includes three technologies: AI scene image quality optimization, HDR10+ support and video HDR enhancement.

In AI scene quality optimization (AI-PQ), the engine can dynamically adjust the contrast, sharpness and color of each frame according to AI scene recognition. At the same time, it also supports HDR10 and HDR10+ image quality standards, which can adjust the image details and dynamic range of 4K video images frame by frame.

In terms of video HDR enhancement, MiraVision image quality engine can realize real-time partition operation of 4K images, and enhance the ordinary SDR video source to HDR display effect in real time while further improving the high dynamic range of video.

In the application of AR, Dimensity 1000+ uses ISP (image signal processing) image technology, based on the AI computing ability of APU 3.0, and supports five hand recognition models: Detection, Tracking, Skeleton, Gesture and Verification.

At the same time, it also supports real-time operation of AI 3D gesture tracking, including detecting human gestures, multi-joints and degrees of freedom, position and rotation of hands in space, and performing real-time rendering and seamless splicing of pictures.

In the media interview after the meeting, Li Yanji mentioned that AI technology is still in the high-speed development stage, and there are more and more AI applications on mobile phones, including camera algorithms, while MediaTek has been actively developing advanced image processing technology, making full preparations for market competition.

In addition, with the gradual maturity and landing of 5G technology, video has become an important explosion point. This time, Dimensity 1000+ has also made a series of optimizations and upgrades for 4K video.

So what important plans has MediaTek made in the 8K field?

In Li Junnan’s view, at this stage, 8K technology is still in the stage of technology demonstration, and the resolution of most mobile phones and TVs has not reached the 8K standard. Therefore, MediaTek will still focus on the improvement of 4K technology, but 8K technology is also under development.

Through this release, we can see that compared with Dimensity 1000 chip, Dimensity 1000+ not only has lower 5G power consumption and 144Hz screen refresh rate, but also has upgraded the game and video call experience to varying degrees.

With the release of Dimensity 1000+, MediaTek Dimensity 1000 series has three flagship chip products: Dimensity 1000L, Dimensity 1000 and Dimensity 1000+.

In fact, as an upgraded version of Dimensity 1000 chip, Dimensity 1000+ is not a performance improvement and supplement for MediaTek’s previous Dimensity 1000 series.

But from another perspective, Dimensity 1000+ meets the demand of low power consumption and low latency for 5G technology, which further provides an effective solution for the increasingly mature and huge 5G application scenarios.

In the short term, iQOO mobile phone equipped with Dimensity 1000+ will be on the market soon. Will Dimensity 1000+ bring you more surprises? We will wait and see.

These days, friends, friends and WeChat groups can always see everyone’s concern about nucleic acid detection and discuss the COVID-19 epidemic. Since then, nucleic acid detection has become a high-frequency word. But do you really know about nucleic acid testing? What is the nucleic acid strategy under the most severe and complicated situation faced by Chongqing since the COVID-19 epidemic?

In this issue of "Knocking on the Blackboard", Xiaobian will focus on these issues.

The role of nucleic acid detection—It is recognized by the medical communityThe "Gold Standard" for Diagnosing Covid-19

Why do you want to do nucleic acid testing? On November 27th, at the 150th press conference on the prevention and control of COVID-19 epidemic in Chongqing held by Chongqing Municipal Government Information Office, Li Pan, deputy director of Chongqing Municipal Health and Wellness Committee, once again stressed clearly:

Nucleic acid detection is the "gold standard" recognized by the medical community in diagnosing Covid-19. It is an important measure to quickly find infected people, lock the source of infection in time, and quickly cut off the route of transmission. It is a key measure to realize early detection, early reporting, early isolation and early treatment.

(Related links: press conference, responding to concerns-will you be infected in the process of making nucleic acid? What is the difference between regional nucleic acid and expanded nucleic acid?)

At the 147th press conference on November 22nd, Luo Fei, an expert from Chongqing CDC, made an analogy.

If antigen testing is an auxiliary team and nucleic acid testing is the main player; antigen testing is an attack by innuendo, then nucleic acid testing is the final word.

(Related links: press conference, responding to concerns-which is more useful, antigen or nucleic acid? Is the nucleic acid test result true?)

From a professional point of view, the positive result of nucleic acid detection can be regarded as the same as the result of virus culture and then detection. Covid-19 nucleic acid detection is to select two or three characteristic sequences on the virus genome, copy and amplify them, and then detect and compare them, which is what we often call double-target or triple-target detection.

Because the conservative gene sequence of virus is usually selected as the target gene in nucleic acid detection, even if the virus mutates, it has little effect on the detection ability. Nucleic acid detection requires high detection reagents, detection facilities and equipment, and requires professionals to complete more complicated processes such as collection and detection.

---

• Xiaobian analogy-
• Nucleic acid testing is like "raising a baby chicken". When the chick is very young, most people can’t see the male and female, but when the chick is raised, you will know it when you look at the comb.
• Why does it take several hours for nucleic acid testing to produce results? In fact, it is to cultivate viruses, or to raise chickens. Covid-19 nucleic acid detection is equivalent to using cockscomb as a feature to identify male and female, which is the so-called "target gene". At the same time, it is not easy to misjudge if it is characterized by cockscomb, but it is easy to misjudge if it is characterized by chicken feet and tail, so cockscomb is the so-called "conservative gene".

---

At the 151st press conference on November 27th, Liao Pu, director of the Laboratory Department of Chongqing People’s Hospital and deputy director of Chongqing Clinical Laboratory Center, also explained the nucleic acid detection.

(Related links: Why is nucleic acid detection the "gold standard"? What about "false yin" and "false yang")

At present, Covid-19 nucleic acid detection usually uses fluorescence PCR amplification technology, and its principle is that viral nucleic acid is increased exponentially through one cycle, so as to realize Covid-19 nucleic acid detection. This is a very classic and reliable nucleic acid detection method, and it is a technology that won the Nobel Prize.

In the detection process, the yin and yang of the detection results are objectively judged by the circulating threshold of nucleic acid amplification, that is, Ct value. The Ct value is related to the viral load of the infected person. The lower the Ct value of the infected person, the higher the viral load of the infected person. Conversely, the higher the Ct value, the lower the viral load of the infected person.

For the report of positive results, according to the detection strategy, one or two other nucleic acid detection reagents that are more sensitive and amplify different regions will be used to detect the original samples when necessary, and the positive results will not be reported until they are confirmed, so sometimes the detection time is longer.

Although nucleic acid detection technology is the recognized gold standard in Covid-19, it is an internationally recognized detection technology for mature pathogens. However, the so-called "false negative" may appear in unreasonable sample collection, transportation and processing, too low virus droplets in the sample, variation of the target sequence to be detected or sequence change caused by other reasons.

For sudden and new subtype Covid-19, such as Omicron mutant, which has the characteristics of concealment, the optimal sampling time for detection may not be confirmed. In addition, in the process of sample collection and detection, pollution caused by aerosol will occur, resulting in false positive. By strengthening laboratory quality control, monitoring laboratory environment and equipment pollution, and multiple rounds of nucleic acid screening, we minimize the errors caused by technical reasons.

Strategies for nucleic acid detection-different strategies at different stages according to the needs of epidemic situation.

These days, users always leave messages asking questions. Why do you do nucleic acids in different areas?

Indeed, since November 1, especially since November 12, when the coordinated prevention and control of the central city was carried out and the epidemic annihilation war was launched, the Chongqing epidemic prevention and control headquarters adopted different nucleic acid detection strategies at different stages according to the needs of the epidemic situation.

For example, the social inspection has been carried out once every seven days, once every day and every other day. After the city launched the social clean-up attack, according to the deployment of classified attack, all districts and counties were divided into three categories: relatively stable epidemic situation, fluctuating platform period and severe situation, to carry out nucleic acid testing.

Li Pan spoke carefully at the press conference on the evening of November 26th. Under the provisions of the ninth edition and Article 20, various localities will formulate different strategies according to the situation of this area, street, community and even community. Specific to this round of epidemic in Chongqing:

At the beginning of the epidemic, the central city of annihilation was fought-

The epidemic situation is multi-point, multi-source and multi-chain. I don’t know where the potential infected people are, and the chain is unclear. For example, "I don’t know where the’ enemy’ is", then take the whole central city as a whole and carry out nucleic acid testing all over the region, and do it every day, which is to find out the potential infected people. After searching for a period of time, I marked a high-risk area.

Fight the tough battle in the central city in the stage of social clearing-

At this time, it is: high-risk areas should be zoned quickly, and nucleic acid testing should be carried out at the specified frequency in high-risk areas; in other areas, because there is still community transmission, it is necessary to "check every other day" and strive to promote social clearing.

Yuzhong, Jiulongpo, Jiangbei and Yubei made three rounds in three days-

Li Pan said at the press conference on the evening of November 26th that the epidemic situation in all districts of the central city was divided, and some districts added thousands of people a day, with a high proportion of society.

Therefore, just like the annihilation war at the beginning of the epidemic, Yuzhong District, Jiulongpo District, Jiangbei District and Yubei District decided to make three rounds in a row for three days, and continue to exert their strength and concentrate their efforts to find out the potential infected people and the risk sources in a short time.

Similarly, the same is true of Liangping, Dianjiang and Xiushan. The difference is that it is not the whole district (county), but the streets where the county is located and the streets involved in the epidemic.

Xiaobian said so much, we can see that the nucleic acid strategy must be a specific arrangement made according to the current epidemic situation. It is about strategy and actual situation. I hope parents will understand and support it.

Organization of nucleic acid detection-this is an important link, and the organizer must pay attention to it.

This point, Xiao Bian should remind the organization unit of nucleic acid detection, because it is really important.

The organization of nucleic acid detection directly affects the detection quality and screening effect. Staff organization, testing resource allocation, testing object organization, and centralized sampling or sampling by building, unit and floor are all important factors.

For example, on November 26th, some districts and counties reported that "nucleic acid test samples were left behind", which may affect the accuracy and quality of nucleic acid screening for whatever reason, indicating the importance of organizational work.

At the same time, there are still many people who are concerned about the organizational level of nucleic acid testing institutions and the professional ethics of staff, which will also directly affect the testing quality and screening effect.

For the sake of everyone’s health and this city, please ask the organizers of nucleic acid testing to follow the process, make the work meticulous and put the management in place! Please!

(Related links: press conference, responding to concerns-Is nucleic acid testing true or not? Are you sure?)

Can nucleic acid be infected? Everyone should take personal protection, so don’t worry about it.

This point, Li Pan also made a detailed introduction. In fact, you don’t have to worry about doing nucleic acid testing and being infected.

Statistics show that more than 60% of the newly infected people are residents of the same building, the same neighborhood and the same community. The route of infection is often in community activities, with acquaintances and friends, shopping together, and taking express mail together (among them, infected people), without protection or standardized protection and contact.

However, there are very few cases of infection directly in the queue of nucleic acid collection or in the process of nucleic acid collection, but the results of flow adjustment are not supported, so don’t worry.

For high-risk areas, there are positive buildings and units that are tested at home, not to mention worrying.

Look, really don’t worry too much. As long as everyone takes personal protection and adheres to the "one meter distance", this situation can be put an end to.

(Related links: do nucleic acid, remember "5321"!)

Supervision of nucleic acid detection-never be soft when it comes to the end, and please continue to supervise the general public.

On November 24th, at the 148th press conference, Dan Yanzheng, deputy mayor of Chongqing Municipal Government, commander of the municipal epidemic prevention and control command department and director of the comprehensive office, said: At present, the results of nucleic acid testing in the whole city are authentic, so please rest assured.

He said-

Chongqing Municipal Party Committee and Municipal Government have always attached great importance to the quality of nucleic acid detection. In this round of epidemic, in view of the laboratory quality problems with a large amount of detection and public concern, on the basis of monthly laboratory quality assessment and quality control spot check in the early stage, the Municipal Health and Health Commission strengthened management supervision, with municipal quality control experts "conducting daily inspections" and district and county experts "guiding at the station", participating in laboratory management throughout the process, and promptly urging and rectifying problems such as irregular management and process of individual laboratories.

For violations of laws and regulations, we will maintain a high-pressure situation, and immediately start the investigation procedure according to law for the detection errors reflected by the public. Once found, hell to pay.

Ability of nucleic acid detection-Thanks to the strong support of brother provinces and cities, the ability of nucleic acid detection in Chongqing has been enhanced.

Everyone must have noticed that the staff and volunteers of nucleic acid detection are very hard: airtight protective clothing is worn for most of the day or even a day; alcohol cleaning gloves are constantly rubbed, cotton swabs are torn open and carefully sampled …

Especially in the face of this round of large-scale epidemic and large-scale nucleic acid detection, the whole nucleic acid detection system in our city is facing the pressure of long-term and full-load operation, and there are problems such as staff fatigue, high-speed operation of nucleic acid system and obvious lack of detection ability.

In this regard, under the guidance and support of Chongqing Working Group of the State Council Joint Prevention and Control Mechanism, Chongqing has received strong support from some brother provinces and cities, which has enhanced the strength of nucleic acid detection in our city.

(Related links: Medical teams from 8 provinces and cities in China rushed to Chongqing and successively entered Cuntan and Yuelai Fangcang Hospital to carry out medical treatment.)

What should we do-participate in nucleic acid testing as required!

Li Pan said that the majority of medical workers are fighting hard, hoping to eliminate the doubts of some citizens through continuous efforts and higher-quality nucleic acid testing.

What should we do personally to support nucleic acid testing? It’s simple—

Participate in nucleic acid testing as required! This is not only responsible for personal health, but also the need to prevent others from being infected.

At present, the incubation period of Covid-19 is usually 2-4 days, the shortest may be 1 day, or even less than 1 day, and the longest may be 8 days. Therefore, the management policy for close contacts is "5+3" (5 days of centralized isolation and 3 days of home observation) to minimize risks.

The high-risk area is managed by this scientific law, and it will be reduced to a low-risk area after 5 days without sunshine. But this does not mean that there is no risk, and we must continue to observe. If there is mobility, contact, activity and aggregation in the high-risk area, it will cause new infections. If there is a new positive test, the time will be recalculated.

Therefore, lifting the high-risk area does not mean unsealing, but also strengthening observation. In particular, the current epidemic situation in the central city is still severe and complicated, and it is still the coordinated prevention and control of the central city and the implementation of social control.

Here, Xiaobian asks everyone to understand, support and cooperate with various prevention and control measures as always, especially for nucleic acid testing-

Dear friends, don’t give up and refuse the nucleic acid you should do. Only by doing a thorough examination can you find the infected person as soon as possible, block the transmission chain, win a complete victory in the annihilation war as soon as possible, and return to the fireworks of this city as soon as possible.

　　On January 19th, the State Council held a press conference. The relevant person in charge of the Ministry of Industry and Information Technology introduced the development of industry and informatization in 2023 and answered questions from reporters.

　　The relevant person in charge pointed out that in 2023, the added value of industrial enterprises above designated size increased by 4.6% year-on-year, and 28 of the 41 major industrial sectors maintained growth. For the first time, the export volume of "new three products" exceeded one trillion, and the shipbuilding market share ranked first in the world for 14 consecutive years.

　　In 2023, automobile production and sales exceeded 30 million vehicles for the first time, with production and sales reaching 30.161 million vehicles and 30.094 million vehicles respectively, up by 11.6% and 12% year-on-year, reaching a record high and ranking first in the world for 15 consecutive years. In 2001, 4.91 million vehicles were exported, a year-on-year increase of 57.9%, ranking first in the world for the first time.

　　In addition, the Ministry of Industry and Information Technology and relevant departments will guide financial resources to increase support for major strategies, key areas and weak links in manufacturing. The balance of medium and long-term loans in the manufacturing industry has maintained a growth rate of around 30% for three consecutive years, and the financing scale of the national industry-industry integration platform has increased by 68% year-on-year. In the next step, we will focus on bio-manufacturing, artificial intelligence, inland river ships, low-altitude economy and other fields to explore early hard science and technology projects, guide financial capital, social capital and industrial capital to continue to invest, and at the same time continue to do a good job in listing and cultivating enterprises with the joint stock exchange.

　　The industrial added value increased by 4.6%.

　　Xin Guobin, Vice Minister of the Ministry of Industry and Information Technology, pointed out that in 2023, the added value of industrial enterprises above designated size increased by 4.6% year-on-year, an increase of 1 percentage point over 2022. Among them, the added value of industrial enterprises above designated size increased by 5.0% year-on-year. The overall scale of manufacturing industry ranks first in the world for 14 consecutive years.

　　Specifically, industrial production has stabilized and accelerated, and 28 of the 41 major industrial sectors have maintained growth. The ten key industries are basically stable, with an average growth rate of over 5%. The production growth rate of electrical machinery and equipment, automobiles and other industries all exceeded 10%, and the industrial added value growth rate of the automobile industry reached 13%.

　　The industrial economy of most provinces has recovered steadily, and the industrial added value of most provinces has increased year-on-year, and the growth area of provinces has increased by nearly 20% compared with 2022. The growth rate of 8 of the 10 major industrial provinces is higher than the overall growth rate of industrial added value in the national regulations. The growth rates of Jiangsu, Shandong, Anhui and other provinces all exceeded 7%.

　　The benefits of enterprises have steadily rebounded. By the end of November 2023, the losses of industrial enterprises have been narrowing for eight consecutive months since April 2023. The growth rate of operating income of industrial enterprises above designated size has rebounded for five consecutive months.

　　Investment in industrial fixed assets maintained growth, with a year-on-year increase of 9%; Investment in fixed social assets in the whole society increased by 3%. Among them, the growth rate of manufacturing investment has accelerated since August 2023, and the growth rate of investment in automobiles, electrical machinery and equipment, chemicals, non-ferrous metals and other industries is higher than 10%.

　　In addition, the market is expected to be stable and positive. By the end of November 2023, the number of industrial enterprises above designated size had reached 483,000, an increase of 32,000 compared with the end of 2022. The expected index of manufacturing PMI production and operation activities has risen for three consecutive months since October 2023, and the annual index is higher than the critical point.

　　Automobile exports ranked first in the world for the first time.

　　In 2023, China’s automobile industry made a breakthrough. Xin Guobin pointed out that last year, automobile production and sales exceeded 30 million vehicles for the first time, and the production and sales reached 30.161 million vehicles and 30.094 million vehicles respectively, up 11.6% and 12% year-on-year, reaching a record high and ranking first in the world for 15 consecutive years. The retail sales of automobiles reached 4.86 trillion yuan, accounting for 10.3% of the total retail sales of social consumer goods, and the added value of industrial enterprises above designated size of automobile manufacturing increased by 13% year-on-year.

　　New energy vehicles continue to lead the world. In 2023, the production and sales of new energy vehicles were 9.587 million and 9.495 million respectively, up by 35.8% and 37.9% respectively, and the sales of new cars reached 31.6% of the total sales of new cars.

　　Foreign trade exports have further stepped up to a new level. In 2023, the total vehicle export was 4.91 million, up 57.9% year-on-year, ranking first in the world for the first time. Among them, the export of new energy vehicles was 1.203 million, a year-on-year increase of 77.6%. Power battery exports reached 127.4 GWh, up 87.1% year-on-year.

　　Xin Guobin also pointed out that the development of the automobile industry still faces many challenges-most new energy automobile companies have not yet achieved profitability, there are shortcomings in areas such as automotive chips, and insufficient coordination on the development of intelligent networked vehicles.

　　For the next stage to promote the high-quality development of the automobile industry, the Ministry of Industry and Information Technology has made the following arrangements:

　　First, we will implement preferential policies such as tax reduction and exemption for the purchase of small cars, carry out comprehensive electrification pilot projects for vehicles in the public sector and activities of new energy vehicles going to the countryside, actively expand the consumption of new energy vehicles, and maintain stable industrial operation.

　　The second is to support enterprises to carry out joint innovation, increase technical research on vehicle chips, all-solid-state batteries and high-level autonomous driving, and further enhance the market competitiveness of products.

　　Third, organize the pilot application of intelligent networked vehicle access and "vehicle-Lu Yun integration", speed up the construction of infrastructure such as roadside perception and networked cloud control, further improve the standard system of vehicle end, road end and network end, and further promote the commercial application of intelligent networked vehicles.

　　The fourth is to further strengthen the overall layout of industrial development, prevent and resolve the risk of overcapacity, and maintain fair competition market order. Continue to promote the international development of the automobile industry, promote the elimination of various forms of trade protection policies, and create a good international and domestic environment for industrial development.

　　The United Stock Exchange should do a good job in listing and cultivating enterprises.

　　The 2023 financial work conference pointed out that it is necessary to adhere to the fundamental purpose of financial services to the real economy. Xin Guobin said that at present, the Ministry of Industry and Information Technology has carried out strategic cooperation with 22 financial institutions across the country, initially forming a work pattern of industry-integration, which is coordinated by departments, coordinated by central and local governments, coordinated by various policies, and widely participated by financial institutions. The data shows that the balance of medium and long-term loans in the manufacturing industry has maintained a growth rate of around 30% for three consecutive years, and the financing scale of the national industrial integration platform has increased by 68% year-on-year.

　　Relying on the hard science and technology attribute evaluation and listing cultivation mechanism jointly established with the stock exchange and local supporting policy incentives, we will guide social capital to invest early and invest small in hard science and technology, and build a sustained and stable innovation investment mechanism to make up for shortcomings, forge long boards and strengthen foundations. In the engineering stage, leading enterprises or dominant enterprises in the industrial chain put forward R&D needs, determine the respondents by "revealing the list" and other ways, include R&D projects in the scope of hard technology, encourage investment institutions to support R&D activities, and promote further supporting preferential policies where the projects land. In the stage of industrialization and marketization, some preferential loans, industrial investment, insurance compensation and other policies should be adapted accordingly to help innovative achievements quickly open up the market, including market verification and technical iteration.

　　Xin Guobin made it clear that this year, the Ministry of Industry and Information Technology will continue to further promote the integration of production and operation and strengthen cooperation with financial management departments. Expand the implementation of the special scope of "financial integration of science and technology industry" and hold special roadshows for the transformation of scientific and technological achievements in colleges and parks. Continue to carry out the construction and evaluation of hard science and technology attribute evaluation standards in subdivision fields. Focus on bio-manufacturing, artificial intelligence, inland river ships, low-altitude economy and other fields to explore early hard science and technology projects, guide financial capital, social capital and industrial capital to continue to invest, and at the same time continue to do a good job in listing and cultivating enterprises with the joint stock exchange, unblock the channels for capital withdrawal, promote the further virtuous circle of "science and technology-industry-finance" and promote the construction of a modern industrial system.

　　Promote the research and development of 5G-A and 5G lightweight products and accelerate the research of 6G technology.

　　In 2023, China’s information and communication industry grew steadily and continuously, and 5G innovation and development led the world. Zhao Zhiguo, spokesperson and chief engineer of the Ministry of Industry and Information Technology, said that by the end of 2023, the total number of 5G base stations in China had reached 3.377 million, the network base was further consolidated, and the network applications were constantly enriched. Applications in the 5G industry have been integrated into 71 national economic categories, with more than 94,000 application cases and 29,000 virtual private networks in the 5G industry. The application of 5G has been deeply promoted in industries such as industry, mining, electric power, port and medical treatment.

　　The continuous growth of 5G mobile phone users and the rapid increase of 5G traffic consumption have promoted the vigorous development of emerging services such as naked-eye 3D and cloud mobile phones, effectively expanding the development space of the mobile communication market. By the end of last year, there were 805 million users of 5G mobile phones, and 5G network access traffic accounted for 47%. According to the calculation of research institutions, it is estimated that 5G will directly drive the total economic output by 1.86 trillion yuan in 2023, an increase of 29% over 2022.

　　The prospect of comprehensive utilization of waste power batteries can be expected

　　Green and low-carbon is the production background of new industrialization. When asked about the achievements of industrial green and low-carbon transformation in 2023, Tao Qing, spokesperson of the Ministry of Industry and Information Technology and director of the Operation Monitoring Coordination Bureau, responded that the industrial structure has been continuously optimized, and backward production capacity in industries such as steel, electrolytic aluminum, petrochemical industry and building materials has been further withdrawn, and 78 steel enterprises have completed the whole process of ultra-low emission transformation with 390 million tons of crude steel production capacity.

　　The release of green kinetic energy is accelerated. The 16 MW offshore wind turbine with the largest single unit capacity in the world has been successfully connected to the grid for power generation, and the output of the main links in the photovoltaic industry chain has remained the first in the world for many years. The total output value of environmental protection equipment manufacturing industry is expected to exceed 970 billion yuan.

　　The comprehensive utilization system of industrial resources was further improved. In the whole year, 239 enterprises for comprehensive utilization of renewable resources such as waste steel, waste paper and waste power batteries of new energy vehicles were selected, and the comprehensive utilization of waste power batteries of new energy vehicles was 225,000 tons.

　　In the next step, the Ministry of Industry and Information Technology will continue to promote the implementation of the 14 th Five-Year Plan for Industrial Green Development. In 2024, it is planned to formulate about 100 carbon footprint rules and standards for key products. Vigorously develop green and low-carbon industries such as hydrogen energy and energy storage, improve the requirements of backward production capacity, energy consumption and environmental protection, and accelerate the synergy of pollution reduction and carbon reduction.

　　In-depth implementation of the green manufacturing project, in 2024, we will strive to cultivate 1,000 new green factories at the national level, improve the green manufacturing service system, and pilot the implementation of "enterprise green code". Give full play to the role of national production integration as a platform, and actively create green consumption scenarios in new energy vehicles and green household appliances.

　　Accelerate the construction of waste recycling system and encourage qualified areas to create "waste-free parks" and "waste-free enterprises". Promote the development of industrial norms for the comprehensive utilization of renewable resources. In 2024, the comprehensive utilization of major varieties of renewable resources should increase steadily, improve the emerging solid waste utilization system, and strive to achieve an annual comprehensive utilization of waste power batteries of more than 260,000 tons.

　　The reporter noted that the Ministry of Industry and Information Technology recently announced the fifth batch of enterprises that meet the "Industrial Standards and Conditions for Comprehensive Utilization of Waste Power Batteries in New Energy Vehicles". Up to now, the Ministry of Industry and Information Technology has announced a total of 148 compliance enterprises in five batches, including 85 echelon utilization enterprises and 48 recycling enterprises, and 15 enterprises involved in echelon and recycling at the same time.

　　Feng Yi, general manager of China Automobile Data Co., Ltd., said in an interview with the Securities Times reporter that the comprehensive utilization enterprises of waste power batteries have covered 24 provincial-level administrative regions in China, and the number of comprehensive utilization enterprises in each region basically matches the number of new energy vehicles, which can basically realize the "recycling and disposal nearby" of waste power batteries, and some regions have also formed regional power battery recycling industrial clusters. Driven by market demand, comprehensive utilization enterprises are constantly strengthening the cultivation of R&D and innovation capabilities, and the technical research and technological innovation of the industry are constantly strengthening, so the development foundation of the comprehensive utilization industry will be more solid and the prospects will be more predictable.

Every reporter Du Wei Wen Menghua every editor Dong Xingsheng

Looking for an overseas website to open a shop and sell China goods is attracting more and more businesses and capital.

According to enterprise survey data, in the first half of 2022, more than 20,000 cross-border e-commerce related enterprises were added nationwide. The Data Report of Cross-border E-commerce Market in China in 2022 (I) predicts that the cross-border e-commerce market is expected to reach 15.7 trillion yuan in 2022.

15.7 trillion, the market is very big, and the temptation is also great. "You don’t need to know English, the net profit of a single order exceeds 40%", "You can do it without purchasing channels and goods" and "The guaranteed turnover is 40,000 yuan a month". It is these tempting marketing terms of "cross-border e-commerce" that make dozens of people from all over the country, such as Li Yun from Guizhou, Zhong Yong from Hebei and Yu Wei from Inner Mongolia, fall into the trap of new tricks in just a few days, and some families even fall into it.

What is even more embarrassing is that these businesses don’t even know who they have been cheated by.

"This is a new situation." Li Chengdong, the founder of e-commerce of Dolphin Think Tank, pointed out in an interview with national business daily. Chen Zixing, a lawyer of Beijing Anbo (Chengdu) Law Firm, also told reporters that it was the first time that the seller suffered a "chain scam" case. "The cross-border e-commerce store and the website where the goods were purchased in the case were all fake."

Taking advantage of the information gap at home and abroad, the new deception that lures merchants to enter has cast a shadow over the rising cross-border e-commerce. After more than two months of follow-up investigation, the reporter personally experienced how Li Yun and others were tempted to open stores step by step, trying to break through the tightly woven network of chain scams; And talk to industry authorities, lawyers, etc., restore the reasons behind the new scam, and explore the problems and opportunities of cross-border e-commerce industry.

One ring and one ring: nearly 750,000 yuan was cheated in half a month.

In October 2022, Li Yun, who opened a physical clothing store, was attracted by the "gimmicks" such as cross-border e-commerce to open stores for free and without supply, thinking that he had encountered a "precious" entrepreneurial opportunity. Unexpectedly, she fell into a huge trap.

Under the guidance of the online "teacher", Li Yun opened a shop in Lelong shop that day, and purchased it through "Youhuo.com" and sent it to overseas buyers. Initially, Li Yun quickly received the payment on Lelong shop.

"I checked Lelong, which was established in 1998 and is very famous abroad." According to Liu Yun, in the next few days, more and more orders were placed, and the amount was getting bigger and bigger. "I have more than 100,000 yuan in each order."

Not without doubt. When she invested 4000 yuan, Li Yun called the relevant authorities, but at that time it was not clear whether it was fraud, so she didn’t care. After that, Li Yun opened two more stores in the name of his parents.

From the initial free shop opening, to the payment of several hundred yuan, and then to tens of thousands and hundreds of thousands of yuan, as the order is getting bigger and bigger, like "snowballing", in order to get the payment back, Li Yun has also spent more and more money. In order not to let the previous money go to waste, she can only continue to invest more money. After being unable to pay for the purchase of new orders, all three stores of Li Yun were frozen by the website. The "teacher" told her that she needed to pay a deposit of $50,000 to unblock the store. Until then, Li Yuncai realized that he had fallen into a scam and called the police.

The reporter logged into the backstage of Li Yun’s frozen women’s clothing store and saw that at present, Li Yun’s pending settlement amount exceeds 60,000 US dollars, and the settled amount exceeds 30,000 US dollars (the settlement failed to be withdrawn after the store was closed). "I have already delivered the unsettled and settled goods. I invested more than 600,000 yuan in this store alone." Liu Yun said that in just 15 days, his three stores were frozen successively, and more than 700,000 yuan was invested in Shui Piao. Among them, on the day of the alarm on October 24, 2022, I hit another 100,000 yuan.

For Liu Yun, this more than 700,000 yuan not only spent his savings, but also caught up with his parents’ savings for half a lifetime. What happened to Liu Yun is not a case. The reporter found that more than 30 sellers from all over the country had the same experience on the platform of "Lelong shop" alone. As of January 6, 2023, according to the reporter’s rough statistics, they have been cheated by more than 2 million yuan.

Yu Wei, who lives in Inner Mongolia, told reporters that she found that it was not the same collection account on the third day when she opened the store. She felt that it was not right, but after being induced by the "teacher" to check the backstage payment, she made another 8,000 yuan. "There were 50 orders of about 20,000 yuan that night. I asked the customer service to inform the customer to return the goods on the platform, but there was no response; Negotiating with the’ teacher’, the other party also said that there is no way to close the store and freeze the account if it is not delivered on time. "

Experience the deception of no supply: set big money with small money

"Open a shop without supply" and "Free of any deposit, tuition and consulting fees", and open the advertising links provided by the above sellers. The reporter saw that the advertising language on the poster was very attractive.

After the reporter clicked "consult now", he added the WeChat of "Customer Service of SiteGiant Co., Ltd." through a QR code. According to the other party, Lelong is the largest e-commerce platform in Malaysia, and now it is fully inviting investment from China merchants, with limited places.

When the reporter checked the enterprise information of SiteGiant Co., Ltd., he found that the number was "filled in by individuals" and no relevant information was submitted to verify the authenticity of the main information.

"There is no charge for supporting you to open a shop." The other party repeatedly stressed to reporters. Subsequently, it guided reporters to download ICQ software, and then pulled the group to introduce the operation of "teachers" to guide the opening of stores and selling goods. The reporter’s experience is exactly the same as that of Yang Liang, who works in Germany.

Yang Liang introduced that the "teacher" helped him with how to classify the product map and how to design the logo. At first, the other party was particularly enthusiastic. "Every day, I will help me pay attention to the store dynamics, teach me by hand, and ask me questions." When the store was placed by an overseas buyer, the teacher taught him to go to Youhuo.com to search for the goods the buyer wanted, and then he called the private account provided by Youhuo.com, "Tell me that I don’t pay taxes for my personal business, and I will believe it".

When "Youhuowang" delivers the goods for him, he can fill in the order number back to Lelong shop, which is regarded as the completion of the order. "They said that when the buyer receives the goods, I can go to the store to withdraw money." Yang Liang said, according to the "teacher", "every order will have a net profit of at least 40%. However, the delivery must be completed within 24 hours of the buyer’s order, otherwise it will be regarded as a violation and the store will be frozen. "

Everything went smoothly at first, but with the increasing amount of orders, Yang Liang’s investment in payment became more and more difficult, and the funds began to turn around. He once told the "teacher" not to push the flow and not to take orders first, but the orders were still one after another.

In just one week, Yang Liang’s shop was closed twice for failing to deliver the goods on time. After he scraped together a deposit of $1,000, the "teacher" also blamed him: "Don’t you even have one or two bosom friends?"

Yang Liang tried to contact overseas buyers and negotiate to cancel the order, but found that the other party was empty. When he questioned the "teacher" and asked questions, "The customer has placed an order of 100,000 yuan, and I have no money to purchase it. Can’t I not do this order?" However, it was accused by the "teacher" as an "unscrupulous merchant". "How can you make a phone call without an area code? How much money you prepare, just say in advance, you don’t say … you can’t solve it in violation of the regulations, just say that you have been cheated. "

At this point, Yang Liang just woke up, he is met "kill pig plate". Therefore, I immediately entrusted my domestic friends to call the police.

The public security bureau ran back and forth several times, but I still don’t know who cheated.

Is the Lelong shop where more than 30 sellers have settled in Malaysia?

The reporter called Lelong many times, but as of press time, he did not get a reply. "Lelong is a relatively old e-commerce platform in our country." Su Yanlu, Acting President of China Silk Road Entrepreneurs Association, told reporters that although the company address displayed on the website page of Lelong shop is the same as Lelong’s, there is no registration number required by the local government, and the logo of the two websites are different.

"I cried and begged my mother to trust me and lend me money to do cross-border e-commerce. As a result, I was cheated by nearly 750,000 yuan." After running back and forth several times in the Public Security Bureau, Liu Yun still doesn’t even know who he was cheated by. Another seller, Luo Qian, also smiled bitterly at the reporter: "When I went to the police station to report the case, I was asked the name of the fraudster or company."

No one knows the company information behind Lelong shop, and dozens of sellers also make personal calls to Youhuo. com, and the account number is different every time.

During the interview, almost all sellers mentioned to reporters that online stores sometimes can’t be opened, so they can only contact the "teacher" and use the re-sent website to enter. In this regard, the reporter asked the IT staff, and analyzed the Lelong shop and Youhuo.com mentioned by the seller by technical means, and found that the IP addresses of these two websites would "move" from time to time, but only in Tokyo and Hong Kong, China. "From the analysis results, the high probability is that the same company is operating, and the production price of such websites is low, and one can be made for several hundred yuan."

"The’ teacher’ said that our website is a sub-website of Lelong, which is aimed at China sellers and the company is in Hongkong." The seller, Li Lu, provided several videos to the reporter. After the store was frozen, she found a friend in Hong Kong and asked him to help to ask about the situation at the scene. According to the video recorded by his friend, there is no company related to Lelong shop in the office building where the address is located.

As a result, when the above-mentioned dozens of sellers realized that they were "cheated", they suddenly found out that no one even knew the "complaint" when they consulted a lawyer or reported the case to the police.

An e-commerce industry veteran told reporters that these dozens of sellers may encounter "chain scams", not only overseas stores are fake, but even the purchase website is fake, and there is no so-called overseas buyer at all.

According to the addresses and telephone numbers of overseas buyers provided by several sellers, the reporter called buyers in new york, London and other places for verification, but none of them could be connected, most of which were empty or wrong.

Wearing a cross-border e-commerce coat, online fraud

Before the "reverse Haitao" became popular, many China merchants had been "panning for gold" on platforms such as Amazon and Shrimp Skin. Compared with the capital investment and process of opening stores on these large platforms, criminals are aiming at the psychology that businesses want to try simply.

"This incident is a cross-border e-commerce cloak and online fraud." A veteran of the cross-border e-commerce industry analyzed that Lelong shop and websites with goods are located overseas or are fraudulent, which may make it difficult to implement supervision in China.

"Using overseas servers and virtual IP addresses to carry out illegal activities is a relatively high incidence in recent years, which undoubtedly increases the difficulty and cost of victims’ rights protection, and also increases obstacles and challenges for police investigation." Chen Zixing, a lawyer of Beijing Anbo (Chengdu) Law Firm, said in an interview that although he had been exposed to many cross-border e-commerce disputes, he encountered a case of "chain scam" for the first time.

Chen Zixing believes: "The incident has been suspected of a criminal offence, but it is difficult for the deceived seller to find out and confirm the subject identity and contact address of Lenglong shop by personal strength."

The reporter learned that in desperation, most sellers have used the search platform when searching for "cross-border e-commerce" as the defendant’s main body to report the case to the police.

"If the search platform pushes the relevant links and platforms of lenglong shop as advertisements, it may be recognized as an advertisement publisher. According to the relevant provisions of the Advertising Law, if false advertisements are published to deceive and mislead consumers and damage the legitimate rights and interests of consumers who purchase goods or receive services, advertisers shall bear civil liability according to law. " At the same time, Chen Zixing stressed that if an advertising agent or publisher cannot provide the real name, address and effective contact information of the advertiser, consumers can ask the advertising agent or publisher to pay compensation in advance.

In Chen Zixing’s view, the main problems faced by cross-border e-commerce victims in taking civil judicial channels are: First, it is difficult to determine the identity information of the defendant; Second, it is difficult to deliver judicial documents, and most cross-border e-commerce perpetrators are not in China; Third, it is difficult to implement and collect money. Even if the judgment is successful, there may be no property available for execution.

According to Chen Zixing, there are two main ways to relieve victims’ rights. First, the seller provides the information of the co-payee to the police and reports the case, and the police investigate and recover the money; The second is to take the payee as the defendant and bring a civil lawsuit to the court with jurisdiction to demand the payee to return the money.

Reporter’s Note: The space for cross-border e-commerce to create wealth is far beyond imagination, but it also has many traps.

As a factory in the world, cross-border sellers in China are the targets of major e-commerce platforms.

Relevant data show that in the past five years, the scale of cross-border e-commerce in China has increased nearly 10 times. In 2021, the import and export scale of cross-border e-commerce in China reached 1.92 trillion yuan. The report "Digital Platform Helps SMEs Participate in Global Supply Chain Competition" predicts that by 2025, the B2B market of cross-border e-commerce in China will reach 13.9 trillion yuan.

"As a new Nugget track, cross-border e-commerce has far more room for wealth creation and development than we imagined, but what we see is often only the winners. After people outside the industry actively or passively heard these success stories, they began to understand cross-border e-commerce, but they did not form a complete cognitive system and discrimination ability for cross-border e-commerce." Yao Zhengyi, secretary general of Chengdu cross-border electronic commerce Association, said in an interview.

"When the cross-border sea became a big market, it was also targeted by scammers." Li Chengdong, the founder of Dolphin Think Tank E-commerce, pointed out to the reporter that "doing cross-border e-commerce needs special caution. Sellers are lucky enough to believe that nothing needs to be invested, as long as they open a store, they can make money. "

The reporter learned through a large number of interviews that among dozens of deceived sellers, some people were attracted by gimmicks such as the operation of the marketing number of the "cross-border e-commerce" course on the short video platform. However, after entering, I encountered a fancy scam, and all the shops I opened ended in being frozen.

The seller Liu Li brushed a short video of cross-border e-commerce and came up with the idea of opening a store. After investing tens of thousands of yuan, the particles were not collected; Tian Honghua in Beijing paid nearly 30,000 yuan to find someone to operate on his behalf, and the other party ignored the "freezing" of his store after receiving the money …

There are no quick channels and rules for making money in any industry. Yao Zhengyi suggested that businesses that want to set foot in the cross-border e-commerce industry need to learn through formal channels to avoid falling into traps such as zero supply and fake shops.

As a consumer, the reporter learned from a number of cross-border e-commerce agency companies in the market that the "cooperation package" ranged from several thousand yuan to nearly 50,000 yuan, and promised tens of thousands of dollars a month to the agency stores.

"Last year, many colleagues disappeared." Xiao Le, who has been doing cross-border e-commerce operations for nearly three years, told reporters that the situation is very good, but the market is chaotic. "Those who are irresponsible and play routines will lose trust, and few can persist."

"China enterprises now need to go global. However, the real industry and brand going out to sea require enterprises to establish their own core teams, constantly explore and link resources from all parties to form a complete industry knowledge system. " Yao Zhengyi appealed that in order to make the cross-border e-commerce industry develop more orderly and efficiently, lawyers, scholars and other professionals who have studied the cross-border e-commerce industry can discuss the formation of some rules and mechanisms to avoid new online fraud incidents under the guise of cross-border e-commerce.

　　Beijing, April 11 (Xinhua) Recently, a news about "super fungi" triggered a heated discussion in society. The Beijing Municipal Center for Disease Control and Prevention announced today that the "super fungus" is Candida auricula, which can cause serious infection in hospitalized cases. Healthy people are usually not infected with Candida auricula, which poses a low health threat to the general public.

　　Beijing CDC pointed out that the so-called "super fungus", named Candida auris, is a fungus that can cause serious infection in hospitalized cases. The data show that Candida auricula was discovered only in recent years and was first discovered in Japan in 2009. Through the retrospective detection of stored candida, it first appeared in South Korea in 1996.

　　According to statistics: At present, there are reports of cases of Candida auricula infection on all continents. As of February 28, 2019, there were 587 confirmed cases in the United States. There have been a few cases reported in China.

　　According to the Beijing CDC, because healthy people are usually not infected with Candida auricula, Candida auricula poses a low health threat to the general public, and the public need not panic or take special preventive measures.

　　Who is susceptible to Candida auricula infection? What are the main hazards?

　　Candida auricula can not only cause symptomatic infection, but also be carried in the body without symptoms. Candida auricula infection mainly involves hospitalized cases, and the high-risk population is patients with severe chronic basic diseases or immunosuppression (such as diabetes, chronic kidney disease, HIV infection, tumor, etc.); Newborns, patients with intubation or indwelling catheter, surgical patients and patients who use broad-spectrum antibiotics or antifungal drugs can also be infected. Healthy people usually don’t get candida auricula. The symptoms caused by Candida auricula depend on the location of infection, including bloodstream infection, wound infection and ear infection. Among them, bloodstream infection is the most serious, and the mortality rate can reach 30-40%.

　　What are the main treatments for this fungus at present?

　　At present, the fungus is mainly resistant to fluconazole, but the resistance to other antifungal drugs varies among different strains. At present, there are strains resistant to three main antifungal drugs. Most cases of Candida auricula infection can be treated with echinocandin antifungal agents, and cases of multi-drug resistant Candida auricula infection can be treated with high-dose and multi-antifungal agents.

　　Guangming net news Since the beginning of this year, large language models such as ChatGPT and ERNIE Bot have been popular, and the question of whether artificial intelligence (AI) can surpass human beings has aroused heated discussion. On May 29th, the "2023 China Computing Power Development Seminar" organized by China Intelligent Computing Industry Alliance was held in the Institute of Computing Technology, Chinese Academy of Sciences. The theme of this seminar is the opportunities and challenges of computing power under ChatGPT, which brings together many authoritative experts and scholars in the industry to conduct in-depth exchanges and discussions from multiple dimensions such as technology and ecology, determine the development trend of the liquidation power industry, and give countermeasures for the current artificial intelligence infrastructure and computing power service construction.

　　At the seminar, Chen Runsheng, an academician of China Academy of Sciences, said that the development of artificial intelligence is unstoppable by human beings, which is the essence of scientific development. At the same time, he pointed out that the phenomena of "Breakthrough" and "Grokking" in the big language model deserve our consideration.

　　What is "emergence"? A complex system is made up of many tiny individuals, who come together and interact with each other. When the number is large enough, it shows a special phenomenon that can’t be explained by micro-individuals, which is called "emergence". Chen Runsheng vividly explained, "I gave it (the big model) a lot of learning data, and as a result, there will be something in its answer that is not in the learning data. This phenomenon is called emergence." The calculation of a large model shows that when the training data is large (for example, more than 100 billion), there will be an emergence phenomenon, and this phenomenon will not occur when the scale is small.

　　What needs to be clear is that the emerging phenomenon is controversial in the scientific community at present. For example, a professor at Stanford University thinks this is a metric problem, which involves measurement, basic physical coordinate system and so on.

　　"Emergence in the process of natural language processing due to the rapid increase of the whole computation is a new problem, which is worth considering," Chen Runsheng said.

　　What is an epiphany? Chen Runsheng explained, "In the process of training a neural network, you don’t understand it once, twice, the fourth time, and the fifth time. Just like a child learning something, you don’t understand it once or twice, and you suddenly learn it after teaching N+1 times."

　　He believes that this is a model of human brain learning, "learning to understand at a certain time", "computers can’t have epiphany, but large models will have epiphany."

　　Not long ago, Claude, one of ChatGPT’s main competitors, expanded the number of tokens in the context window to 100,000, equivalent to 75,000 words, which greatly exceeded the 8192 tokens in the context window of GPT-4. This means that users can upload up to 500 pages of documents to Claude, which can understand and digest the information in less than 1 minute and answer users’ questions based on the uploaded information.

　　Claude was launched by Anthropic, a company founded by former OpenAI employees. Since the end of 2022, Google has invested nearly $400 million in the company.

　　In this regard, Chen Runsheng believes that the current learning speed of large models is much faster than we thought. "These two companies (OpenAI and Anthropic) are catching up with each other. Maybe after a while, GPT-5 will be stronger than Claude, and it will develop so fast that people will not catch up in the future."

　　"What’s more troublesome is that these big model companies are considering manipulating third-party equipment," Chen Runsheng said. "Being able to manipulate third-party equipment is a worrying thing. If you manipulate things related to safety and national defense, it will be terrible."

　　Chen Runsheng admits that the structure of human neural network is much more complicated than the current big model, and the development of artificial intelligence still has a long way to go. "The current (artificial intelligence) neural network should have revolutionary changes in the spatial structure model. Maybe at that time, (AI) can really surpass human intelligence."

Remember the flu "shock wave" this spring? The resurgence of influenza A (H1N1) subtype caused the school to suspend classes in a large area, and the children who had returned to school were returned home because of the flu. However, the affected children have suffered a lot, and symptoms such as headache, high fever and cough are indispensable, and parents are also worried.

As the weather gets colder and the seasons change alternately, the influenza virus becomes active. Prevent the flu, get vaccinated, now!

What is the flu?

Influenza, referred to as "flu" for short, is usually an acute respiratory infectious disease caused by influenza A or B virus. It is highly contagious and people are generally susceptible. The main manifestations are acute onset, severe systemic symptoms, sudden chills, fever, headache, systemic aches, stuffy nose, runny nose, dry cough, chest pain and other symptoms. Unlike the common cold, influenza is prone to pneumonia. In severe cases, acute respiratory distress syndrome and septicemia may occur, and if not treated in time, it may even lead to death.

　

　　A 12-year-old boy in Changchun was blinded by a woman with a sharp knife and pretended to be dead to save his life.

　　Nandu News reporter Li Rong On October 11th last year, a 12-year-old boy Xiao Shuo (a pseudonym) was visiting the grocery store at home in Bao ‘an Village, Xinli Town, yushu city City, Jilin Province, when he was suddenly attacked by Wang (female), a villager in the same village. He was stabbed dozens of times, his eyes were seriously injured, his right eyeball had been removed, and his left eye was completely blind. After the incident was exposed by the media, it attracted the attention of the whole society. The child’s sentence "What time is it, mom? It’s all dark" has also touched the hearts of people all over the country. An eye hospital in Shenzhen provides free assistance to Xiaoshuo’s family. On October 22 last year, Xiao Shuo went to Shenzhen with his family for treatment, and now he has seen the light again.

　　The hospital set up an expert group to repair the appearance of Xiaoshuo’s removed right eye, and at the same time, treated Xiaoshuo’s left eye with integrated Chinese and western medicine to help reduce eyeball pressure, promote blood circulation, prevent infection, diminish inflammation and swelling, improve optic nerve function and antioxidant treatment. After more than two months of persistent treatment, Guangming finally came in quietly: Xiaoshuo saw the colored lights decorated on the Christmas tree in the hospital on December 18th, and could distinguish different colors.

　　"We don’t know how to thank the dean and the hospital staff." Father Zhu Fu said, "I only hope that one day Xiaoshuo will grow up, listen to Dean Lin, study hard and be a useful person to society." When Xiaoshuo was asked about his outlook for the future, he said that he would study hard and hope to be a doctor in the future to help more patients in need.

　　Earlier media reports:

　　A 12-year-old boy was blinded by a woman with a sharp knife when he was alone at home watching the shop.

　　New Culture News (Reporter after reporter) Yesterday, outside the operating room of the Second Hospital of Jida University, a 50-year-old rural woman’s eyes were glazed, her mouth kept reciting the name of her son Xiaoshuo (a pseudonym), occasionally craning her neck and looking at the closed operating room door … …

　　Her name is Wang Yuying, from Group 5, Bao ‘an Village, Xinli Town, yushu city. In the operating room a few steps away, her 12-year-old son is undergoing the second operation.

　　Everything started with the nightmare on the 11th. That morning, she and her husband went out to work, and her 12-year-old son was left in his grocery store to sell goods. Suddenly, he was attacked by Wang, a villager in the same village — — — After Wang knocked Xiaoshuo down with a beer bottle, he took out a sharp knife and stabbed Xiaoshuo’s eyes, chest and abdomen, causing Xiaoshuo’s eyes to be almost blind and his abdomen to penetrate.

　　By playing dead, the alert Xiaoshuo survived and escaped. Wang ignited the grocery store after the murder, and her body was later found, with a pesticide bottle next to it. At present, yushu city Public Security Bureau is investigating the case.

　　After a long wait, the news from the operating room made the family sad and happy. The good news is that Xiao Shuo’s life was temporarily saved after two operations lasting for 16 hours. However, this 12-year-old intelligent boy may never see the light again … …

　　The couple who went out for the autumn harvest received unfortunate news:

　　"A relative called anxiously and said that his son had an accident at home."

　　The husband and wife run a grocery store in the village. In addition, they have farm work to do.

　　At 5 o’clock in the morning on the 11th, just before dawn, Wang Yuying and her husband got up. After breakfast, they packed up and prepared for the autumn harvest. Although there is not much land at home, they can be free as soon as they finish their work.

　　Just about to go out, Wang, a villager from the same village, came to their home. "Whether to want fertilizer money? 1,000 yuan, you can take it! " Wang Yuying took out 1000 yuan money and handed it to Wang. Wang took the money and looked polite. When he left, he also took away some cigarettes they sent.

　　"Son, we went to work. Today, you don’t go to school, rest at home, take good care of the grocery store, and be obedient … …”

　　When she left home, Wang Yuying repeatedly told her 12-year-old son Xiao Shuo, hoping that he would not always play and take care of the grocery store at home.

　　After arriving at the cornfield not far away, the couple began to work. "It took about half an hour. A relative of my family called anxiously and said that my son had an accident at home, his face was covered with blood, and the house was on fire. Hearing this, we put down the phone and ran home … …”

　　Recalling that scene, Wang Yuying had a low voice. The couple saw their son lying at the door, his face covered with blood, his house smoking outwards, flames popping out from time to time, and his home and grocery store were slowly being swallowed up by the fire … …

　　The child recalled the injury intermittently:

　　"I found that as long as I don’t move, she won’t stab me any more … …”

　　Wang Yuying and her husband didn’t care about the burning home, so they quickly picked up the child, found a car and took the child to the hospital in yushu city.

　　My son in my arms is badly hurt, but he is still conscious and groans from time to time … … The journey of more than 10 kilometers is so long at the moment.

　　On the way, he recalled his injury intermittently — — — Shortly after Wang Yuying and her husband left home, Wang, a villager who had just taken away 1000 yuan, came back. She walked into the grocery store and found Xiaoshuo alone in the room. First, she asked Xiaoshuo to bring her a bottle of beer, and then she asked for a bag of peanuts, which Xiaoshuo did.

　　"Bring me another ice cream … …” Upon hearing this, Xiaoshuo went straight to the refrigerator of the grocery store. At this time, Wang suddenly lifted the beer bottle, a bottle knocked Xiaoshuo to the ground, and then took out a sharp knife from his body and stabbed Xiaoshuo’s eyes, chest and abdomen. Xiaoshuo struggled to stop Wang’s murder with his hands, and his tendons were cut by a sharp knife.

　　"I was scared at that time. She stabbed me with a knife. I started to fight with her, but I found that as long as I didn’t move, she wouldn’t stab me any more … …”

　　Xiaoshuo recalled that in order to survive, he began to play dead. After Wang stabbed Xiaoshuo several times, he found that he was no longer moving, so he stopped hurting Xiaoshuo.

　　After a while, the child heard the sound of gas leakage from the kitchen, and had a premonition that there might be more misfortune. Having lost sight of things, he began to grope by feeling and slowly climbed to the door. I don’t know how long it took, but he climbed outside the door. At this time, a fire was burning in the home behind him.

　　"I guess she thought she had stabbed her son to death, and then she came to my kitchen, opened the liquefied gas tank, set the liquefied gas on fire, and burned the whole house … …” Wang Yuying was crying, and her emotions were almost out of control.

　　The attending doctor said that he had done his best:

　　"We can only try our best to save his life … … His eyes have zero vision and are almost blind. "

　　After the child was sent to yushu city Hospital, the doctor said that it was incurable and he had to go to a big hospital in Changchun. Therefore, the family quickly rushed to Changchun with Xiaoshuo, and finally came to the Eye Hospital of the Second Hospital of Jida University.

　　Wang Yuying said: "The child also has injuries, but the eyes are the most important. We hope to cure the child’s eyes first … …”

　　At 1 o’clock in the afternoon on the 11th, they arrived at the Eye Hospital of the Second Hospital of Jida University. At 4 o’clock in the afternoon, the child began to undergo surgery. At 11: 58 that night, Xiaoshuo was pushed out of the operating room.

　　After a long wait of 8 hours, at the moment when Xiaoshuo was pushed out of the operating room, the family quickly gathered around: "How are the children’s eyes, doctor?"

　　Doctor Huang Dafu sighed and said that Xiaoshuo’s eyes were badly hurt, and they had done their best.

　　Dr. Huang said that the optic nerve and four muscles in the fundus of Xiaoshuo’s right eye have been cut off by a knife, and the eyeball is prominent, so there is no possibility of recovery. Therefore, the right eye has been removed. At the same time, Xiaoshuo’s left eye optic nerve was seriously damaged, his vision was zero, and his pupils were dilated. The doctor temporarily restored it to its original state, but it is still impossible to judge what it can be restored after treatment.

　　He said that if it is not infected, the best degree may be to see a glimmer of light; If the infection and recovery are not good, then the left eyeball must also be removed. "From the current situation, the doctor can only try his best to save his life, and the operation is more difficult. As a result, his binocular vision is zero and he is almost blind."

　　What caused this tragedy? The boy’s mother said:

　　"It’s because of a little contracted land that it’s really not … …”

　　Why did Xiao Shuo suffer this accident? Wang Yuying shed tears from time to time. "It’s really not because of a little contracted land. We didn’t care, but people cared, and it hurt my son … …”

　　Wang Yuying introduced that the perpetrator Wang was in his 50 s this year, his hometown was in Heilongjiang, his husband died in his early years, and a son was in the field. After returning to the village alone, he had been living in a friend’s house for a year.

　　"After returning to the village, she and the village had a bit of a land contract dispute. Later, the village contracted the half hectare of land to our family, but she disagreed and has been worried. "

　　In the spring of this year, Wang secretly applied fertilizer to this field in advance, but later, Wang Yuying and her husband still wanted the cultivated land back. "We can’t let people fertilize us in vain. On the morning of the incident, she just came to get fertilizer money. We also gave her a few cigarettes, but no one could think of it. She still couldn’t get around this corner and laid hands on my children!"

　　After stabbing Xiaoshuo and setting fire to the house, Wang ran to the backyard of Wang Yuying’s house and smashed all the window glass of the backyard house. "Later I heard that she ran to my barn and committed suicide by drinking medicine!" Wang Yuying said.

　　For the perpetrator Wang, most villagers are reluctant to mention it. A villager said that after Wang returned to the village, he was not very willing to talk, and there was no excessive behavior at ordinary times. Everyone really couldn’t figure out how she could do such an incomprehensible thing.

　　I have borrowed more than 70,000 yuan to save the children, and all the money and things at home have been burned, and there is not a penny left on me … …

　　The mother hopes that good people can help her son.

　　At 4 o’clock in the morning yesterday, after undergoing binocular surgery, Xiaoshuo was once again sent to the operating room of hand and foot surgery to perform surgery on his injured hands and chest. After another 8 hours of surgery, at 12 noon on the 12th, Xiaoshuo was pushed out of the operating room.

　　The doctor said that the child had a broken tendon in both hands, a penetrating wound in the abdomen and multiple stab wounds in the chest. After the operation, the child is no longer in danger, but it needs to be observed in the ICU ward.

　　"This child has a pair of talking eyes. This time, his eyes were injured, and his big eyes were blind!" When interviewed by new culture reporters, some villagers were very sorry. They said that Xiao Shuo was in the sixth grade in the primary school in his village, and his academic performance was not bad. He was usually obedient and never made his parents angry.

　　"This really shouldn’t happen!" A villager sighed. He recalled that after the incident, Xiaoshuo climbed out of the burning house by himself. After climbing to the door, the child did not cry, but cried "Mom" with heartbreak.

　　At present, more things worry the family: their living conditions are average, including half a hectare of contracted land, and there are seven or eight acres of cultivated land at home. This grocery store is also the main source of income for their family.

　　"My son was injured and admitted to the hospital. Our family has already paid more than 70,000 yuan. All the money was borrowed by relatives and friends. All the money and things at home were burned, and there was no penny on me!" Wang Yuying cried and said, "The world is still so big and beautiful. I hope my son can still see this beautiful world, really … …”
