The frequent emergence of antibiotic resistance challenges modern medicine. It is very important to discuss the evolution of resistance to curb its global spread. The evolution of resistance involves a highly complex phenotypic heterogeneous response. Under the treatment of antibiotics, a small number of antibiotic-tolerant cell subsets will appear in the microbial flora with identical genes. The surviving subgroup can’t grow in the presence of antibiotics, but it can grow again after removing antibiotics, resulting in long-term recurrent infection, which is also the key reservoir for subsequent mutation of resistance genes. However, due to the complex heterogeneous response and stagnant growth of tolerance subgroups, it is still a challenge to identify tolerance subgroups from a large number of bacterial populations and track their physiological evolution trajectory.　
　　Recently, the team of Academician Zhu Yongguan from the Institute of Urban Environment, Chinese Academy of Sciences and Cui Li’s research group published in German Applied Chemistry. A research paper entitled an isotope-labeled single-cell Raman spectroscopy approach for tracking the physiological evolution of bacteria towards biological resistance was published. In this study, the heterogeneity of bacterial response was analyzed in situ at a high-precision level by developing a combination of single-cell Raman-deuterium isotope-multivariate statistical analysis, and the differentiation and dynamic changes of phenotypic subsets were sensitively identified from a large number of bacterial populations, which realized the rapid in-situ tracking of bacterial phenotypic physiological trajectory before resistance mutation, providing important guidance for curbing resistance evolution.　
　　In this study, bacteria were repeatedly exposed to clinical therapeutic doses of antibiotics, and antibiotic resistance evolved. In this paper, the in-situ activity of bacteria during evolution was detected by Raman spectroscopy of single cells labeled with heavy water in a culture-independent way. The results showed that the activity of bacteria under antibiotic pressure gradually increased with the treatment cycle without resistance mutation, indicating that its phenotypic tolerance gradually improved. Furthermore, the study uses UMAP multivariate statistical algorithm to analyze the single cell Raman fingerprint interval of thousands of bacteria in all evolutionary stages. According to the physiological response of bacterial phenotype indicated by Raman fingerprint, four phenotypic subgroups differentiated with the evolution of resistance were identified from bacterial populations with identical initial genotypes, namely sensitive flora, primary tolerant bacteria, evolution tolerant bacteria and evolution resistant bacteria, and the dynamic changes of the four subgroups with the evolution process were sensitively captured. So far, based on the heterogeneous response of bacteria in situ phenotype revealed by single cell Raman, researchers have drawn a physiological trajectory map of resistance evolution. Genome-wide sequencing of bacteria verified the revealed phenotype interactively, and analyzed the genetic basis of phenotype. Phenotypic differentiation is very important to maintain the survival and evolution of the whole flora. Because phenotypic differentiation is much earlier than resistance mutation, identifying phenotypic differentiation is of great significance for guiding clinical medication and reducing the occurrence of antibiotic tolerance and resistance mutation. In this study, the Raman spectra of four distinct subgroups were used to dig out the Raman marker peaks of tolerance and resistance mutation, which promoted the rapid and accurate identification of different stages of resistance evolution, especially phenotypic tolerance.　
　　The single cell analysis platform can be extended to a wider range of research on the evolution of resistance induced by antibiotics or non-antibiotic chemicals. In the future, the single-cell Raman can be combined with targeted single-cell sorting and multi-omics technology to realize the accurate correlation between tolerance and resistance phenotype and genotype, and promote the further explanation of evolutionary mechanism. The research work is supported by the "0 to 1" original innovation project of Chinese Academy of Sciences, the innovative research group project of National Natural Science Foundation of China and Fujian Natural Science Foundation.

　　Xinhua News Agency, Beijing, August 8th Question: Did you go to the swimming pool without changing your shoes, the bacteria exceeded the standard by 5 times, and the lifeguard deserted? — — Investigation on hidden dangers of safety and hygiene in swimming places

　　Xinhua News Agency reporters Yan Zhihong, Li Yuze, Dong Xiaohong and Yang Na.

　　It’s midsummer, and swimming and fitness are very popular. Not long ago, the National Health and Wellness Commission issued the "List of Unqualified Places for Swimming Pool Water Quality Spot Check in Some Cities (First Batch)", which showed that some swimming pools in many cities were not up to standard.

　　National Fitness Day is coming, is there any hidden danger in the swimming pool you choose? What skills can help us choose a safe and hygienic swimming pool? Xinhua news agency reporters launched an investigation for this.

　　Chaos, Dirty and Danger: There are still many "swimming" problems in various places.

　　A few days ago, a suspected chlorine leak occurred in a swimming pool in Fangshan, Beijing, which caused many people to feel uncomfortable. At the same time, it made people feel palpitation, but it did not stop people from questioning whether the swimming pool around them was safe and hygienic. The reporter conducted field visits and investigations in Nanjing, Chengdu, Xiamen and other places, and found that there are still obvious hidden dangers in many swimming pools.

　　— — "Chaos". During the visit, the reporter found that some swimming venues did not publicize relevant information as required, and some swimming pools did not properly implement the cleaning procedures before entering the pool. In the Yingpaisi Swimming Pool in Gulou District, Nanjing, the reporter found that except for the residual chlorine content and water temperature of the venue, the self-inspection items stipulated in the national health standards such as the pH value and testing time of the swimming pool were not publicized, and other important data directly related to the health of swimmers, such as turbidity, carbon, total bacteria and coliform bacteria, were not announced. The reporter also saw that many visitors crossed the disinfection and sterilization facilities and directly entered the swimming pool. In addition, there are many people who directly wear slippers or even enter the pool without changing their shoes at all.

　　— — "dirty" The total number of bacteria in some swimming places exceeded the standard, causing adverse reactions among minors. "Several dolls in the class vomited and diarrhea after swimming." Many parents told reporters that after their children learned to swim in the miracle gym in Xindu District, Chengdu, they developed symptoms of fever and upper respiratory tract infection. According to the sampling results of local law enforcement departments, the total number of bacteria in the swimming pool water of the museum reached more than five times the upper limit of the standard value.

　　— — "risk" Some swimming pools are not equipped with life-saving personnel, and some lifeguards "desert". In the Yingpaisi Swimming Pool in Nanjing, the reporter found that during the peak hours of passenger flow on the weekend afternoon, there was no lifeguard in the audience for a long time. When some lifeguards are on duty, they often leave their posts or talk and laugh with their backs to the pool for a long time.

　　Excessive profit-seeking, poor management and weak supervision have become the main causes of "swimming"

　　The reporter’s investigation found that excessive profit-seeking, poor management and weak supervision are the main reasons for the safety and health hazards in some swimming venues in many places.

　　Some swimming venues ignore safety and hygiene standards in order to reduce costs. According to the requirements, swimming venues should be cleaned once a month. A coach of Nanjing Yingpaisi Swimming Pool revealed: "Swimming pools in the market are simply difficult to do." He told reporters that it takes two or three days for a small and medium-sized swimming pool to change water, and it takes longer for a large swimming pool. Not to mention the cost of changing water, the time cost is unbearable for commercial swimming pools. Therefore, in order to maximize profits, some swimming pools often try to reduce the frequency of changing water and washing pools.

　　In addition, some swimming pools "hide" in the community, so it is difficult to implement dynamic supervision. Wu Xiang, deputy head of the Environmental Health Supervision Brigade of Chengdu Health and Family Planning Supervision and Law Enforcement Detachment, said that although the facilities and environment of swimming pools (gymnasiums) in some communities are "superior", there are many water quality problems. For example, the residual chlorine value is lower than the national health standard, and the foot soaking pool does not meet the relevant health standards. He said that this swimming pool is usually "hidden in the building" and it is very difficult to implement dynamic supervision.

　　In addition, the rapid increase of passenger flow in summer and the lack of hard constraints on uncivilized swimmers are also the causes of the problem. In the Xiamen Workers’ Sports Swimming Pool, the reporter saw that the current water permeability of the swimming pool was significantly lower than other times. To this end, Chen Hong, deputy director of Xiamen Workers’ Cultural Palace, explained that the current peak season ticket prices are low, and the sudden increase in passenger flow has brought great pressure to management. The museum replaces more than 100 tons of fresh water for the swimming pool every day, but it still can’t eliminate the pressure of maintaining water sanitation. In addition, Chen Hong also said that there is currently a lack of hard constraints on uncivilized behavior in swimming pools. "We can only euphemistically discourage related uncivilized behaviors, and there is nothing else we can do."

　　In addition, the reporter also learned that due to the lack of effective due diligence supervision mechanism for lifeguards, lifeguards "deserted" a lot, which increased the safety risk.

　　Master these tricks and choose a safe and hygienic swimming pool.

　　The staff of relevant authorities in many places reminded that ordinary swimmers who want to choose a safe and hygienic swimming venue for "cool summer" must master certain skills to identify the safety index because of the lack of professional testing equipment.

　　The first is inspection. The majority of swimmers should take the initiative to check whether the health permit is hung in a conspicuous place and check whether it is within the validity period. We should try our best to know the health quantitative grading rating, the history of water quality sampling and the real-time self-inspection of water quality in swimming places in time, and pay special attention to whether the safety equipment and personnel in the venues are in place, so as to choose a suitable swimming place.

　　The second is the view. Observe whether the sanitation around the swimming pool is clean, bright and ventilated, and whether there is water in the drainage ditch. Besides, it depends on the color of the pool water. If the residual chlorine content in the swimming pool is normal and the water quality is excellent, then the pool water is bright light blue. And the water in the pool should be crystal clear to the naked eye.

　　The third is to smell. Is close to the surface of the water to smell the smell of water, if you can smell the faint smell of chlorine, it is qualified, and the medicine is too strong or even choking, then the concentration of available chlorine may exceed the standard.

　　The fourth is feeling. After entering the water, if the water quality of the pool is excellent, it will feel soft. If it feels hard and astringent, or even itchy, the water quality may be poor.

　　At the same time, a number of swimming venue operators have called for the majority of swimmers to consciously swim in a civilized way and jointly safeguard the health and safety of swimming pools. They suggested that the management department should introduce hard restraint measures against uncivilized swimmers who have repeatedly taught, so that civilization can be implemented and the pool can be cleaned.

　　In addition, the reporter learned that swimmers can also check the sanitary condition of the swimming pool around their location through some apps, and can check the water temperature, pH value, average daily water change rate, residual chlorine in the swimming pool and so on.

CCTV News:The National Health and Wellness Commission recently issued a notice, requiring local grassroots medical and health institutions to provide health services for respiratory diseases in winter and spring. In the past few days, local medical institutions have continued to increase the supply of medical services, improve service processes, and maximize the protection of patients seeking medical treatment.

Community health service center shares the pressure of hospital admission

Recently, the epidemic period of respiratory diseases in winter has been superimposed in many places across the country, and the demand for medical and health services for urban and rural residents, especially children, has increased significantly. In Yaojia Township Health Center, Hengfeng County, Jiangxi Province, the daily number of patients has increased from more than 40 cases to nearly 100 cases, and the visiting time of the health center has been adjusted to 7: 00 am to 8: 00 pm, an increase of 4 hours than usual.

In a community health service center in Jing ‘an District, Shanghai, the fever clinic is open from 8 am to 8 pm every day. Patients do not need to register, and commonly used emergency medicines can be directly distributed to patients in case of emergency. The community can also do antigen and antibody testing.

For parents who have taken their children to the children’s hospital, it is also very convenient to return to the community health service center near home.

Large public hospitals actively carry out pediatric diagnosis and treatment services.

Large public hospitals around the country have also taken various measures to carry out pediatric diagnosis and treatment services. Shengjing Hospital affiliated to China Medical University mobilized personnel, materials and areas as a whole, transformed the adult ward of Shenbei Campus Rehabilitation Center into a pediatric comprehensive ward, and increased the infusion area of Nanhu Campus from one to three.

Do everything possible to tap resources to carry out pediatric diagnosis and treatment services

Recently, the epidemic period of respiratory diseases in winter has been superimposed in many places across the country, and the demand for medical and health services for urban and rural residents, especially children, has increased significantly. The National Health and Wellness Commission recently issued a notice, requiring local grassroots medical and health institutions to provide health services for respiratory diseases in winter and spring, and do everything possible to tap resources to carry out pediatric diagnosis and treatment services.

The circular requires that local primary health care institutions should be fully open to children, and should not refuse medical treatment, and timely release the list of primary health care institutions providing pediatric services in their jurisdictions. Delayed service of pediatric diagnosis and treatment on weekdays in urban community health service centers with large service demand 1-mdash; 3 hours, or as appropriate, on Saturday and Sunday to increase the service hours. Township hospitals, community health service centers and community hospitals that meet the recommended standards of service capacity should take the lead in building independent pediatric clinics.

All localities should establish cooperation, counterpart support and referral mechanisms between general hospitals and primary medical and health institutions under their jurisdiction, determine the pediatric docking of a general hospital for community health service centers and township hospitals, arrange for doctors with intermediate or sub-high titles to make home visits to primary medical and health institutions, strengthen the teaching training for primary medical personnel, and especially help improve the service capabilities of pediatric emergency first aid, early identification of severely ill children, and venipuncture of children. General hospitals should reserve a certain proportion of outpatient number sources to give priority to primary medical and health institutions. Smooth referral channels, guide mild children to give priority to primary medical and health institutions, and refer them to primary medical and health institutions for follow-up treatment if there is a clear diagnosis and stable treatment in general hospitals. Guide the children to the nearest primary medical and health institutions for follow-up, and the general hospital will arrange special personnel to provide telemedicine or online consultation services.

Give full play to the role of family doctors, do a good job in health management services for key populations, and ensure the health needs of "one old and one small". Grassroots medical and health institutions should keep the fever clinic "fully set up and fully open", equip the grassroots medical and health institutions with necessary facilities and equipment such as thermometers and children’s atomizing machines (children’s masks), and equip them with necessary drugs such as antibiotics, antiviral drugs, cough-relieving and expectorant drugs suitable for children.

This wave of large-scale rain, snow and freezing weather before the Spring Festival opens today! This large-scale freezing rain and snow weather has a wide range of influences, a large amount of accumulated rain and snow, a long duration and a large freezing rain area, which is the strongest in winter since 2009 and is extreme. ▼

Accumulated rain and snow are heavy and snow is thick. The snowfall in Shaanxi, south-central Shanxi, southern Hebei, Henan, Shandong, Hubei, northern and eastern Chongqing, eastern Liaoning, eastern Jilin and other places can reach 10 ~ 25 mm, and the local area exceeds 30 mm; The newly added snow in northern and eastern Chongqing, northwestern Hubei, southern Henan, central and northern Shandong, eastern Liaoning and other places can reach 10-20 cm, and the local area can exceed 25 cm.

Freezing rain covers a wide range of provinces.

Noisy and boiling fireworks and oily kebabs stimulate the taste buds … When it comes to the special food in Gejiu City, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, barbecue is inevitable. By the side of the oven surrounded by fireworks, a bench was set up to sit around a table, and a variety of ingredients were "baked" under the charcoal fire.

Small kebab.

Kebab

The kebab is the protagonist of an old barbecue. The pork leg cut to the size of rock sugar is put on a bamboo stick of about 10 cm, and it is roasted by charcoal fire to be golden, shiny, moist and not greasy. It is very enjoyable. An old man who likes to be sweet likes to wrap small kebabs in powdered sugar and then send them to China with satisfaction. The unique rich meat flavor of barbecue is mixed with the sweet and spicy spices, which teases the taste buds.

Hanging liver meat

A plate full of meat is spread on the grill, and you can eat which piece you want. The lean meat full of aroma is wrapped in chewy meat tendons. After roasting, the aroma of meat, charcoal and seasoning is fully integrated, and the aroma is overflowing.

A barbecue that is being baked.

Honey beef

Beef, honey, pepper and many seasonings make the honey beef skewers rich and wonderful in taste. The savory kebabs marinated by the exclusive secret recipe meet with the beating fireworks, and the meat particles are soft, tender and fragrant, intertwined with sweet and spicy, giving the taste buds great enjoyment.

Gedachang

An old man has never been stingy with his food, and even his intestines are baked with originality. The so-called knot in one’s heart sausage is to tie a delicate knot in the pig’s small intestine and sprinkle it with rich seasonings. The refreshing taste of glutinous rice balls makes people want to stop.　

Baked tofu.

Baked tofu

Gejiu’s baked tofu has a variety of styles, including wrapped tofu, dried tofu and stinky tofu, which are constantly "turned over" on the stove and slowly roasted. Diners sit around the stove, bake one piece and then take it away. They wrap a circle in the oil dish and the Chili dry dish and send it to the mouth. The bean, oil and Chili flavors collide to produce a wonderful taste.

The delicious food being baked.

In midsummer, it’s nice to have a hot barbecue with three or five friends. Gejiu barbecue is a dance of oil and meat on the tip of the tongue, a perfect combination of charcoal roasting and sauce blending, and it has become a hot comfort in ordinary life.

Angela Zhang; Angela Chang

1905 movie network news　 Did you get hit by a melon provided by Angela Zhang this afternoon?

Christine, Angela Zhang

It is said that the feud between Angela Zhang and Christine has a long history, which may date back to 8 years ago. …

At that time, Angela Zhang and Christine, both of whom belonged to Fumao Record Company, were still related to each other. Christine was a fellow teacher and sister of Angela Zhang, but Angela Zhang got ahead.

Christine; Fan Fan

You know, Christine has always been Fumao’s "own daughter". In 2000, she debuted with the album "Fan Fan’s World", and with the rhythm of an album almost every year, she also won her place with her distinctive timbre and the appearance of an oxygen beauty. In 2006, she also challenged to be a variety show host. Although her hosting skills were lacking, the style of silly elder sister was also considered by the outside world as her "truth" and "simplicity" and became an example of high-quality idols at that time.

Angela Zhang; Angela Chang

However, Angela Zhang was not favored at the beginning of her debut, but with her wonderful performance in many idol dramas, the sweet and lovely Angela Zhang gained a lot of popularity and became the queen of idol dramas at that time. The songs performed in the play are also very popular, such as "Lost Beauty" and "Invisible Wings" … After that, many records and idol dramas made Angela Zhang quickly popular on both sides of the strait.

"if things" MV

In 2005, in order to "kiss his daughter" Christine, Fumao tied Angela Zhang and Christine, who were in the limelight, and a song "What If" was born. Later, under the arrangement of the company, the cooperation between the two people broke out frequently, which made this "plastic sisterhood" warm up.

Angela Zhang Christine’s early intimate photo.

But at that time, it seemed that the two were really like sisters, and their feelings were very good. No matter what the occasion, Angela Zhang takes Christine with him, and almost all the guests in each concert are Christine.

Christine (left)Claire Kuo (middle) Angela Zhang (right)

Under the fermentation of "sisterhood", Christine’s popularity has also been improved. Fumao seems to have enjoyed the benefits, and won the popularity of Claire Kuo through the influence of Angela Zhang and Christine.

However, during this period, there were rumors from time to time that Angela Zhang and Christine did not agree because of the "dispute of one elder sister".

Until 2008, Angela Zhang stopped work due to a heart attack and went back to Canada to recuperate. Later, Zhang’s mother broke the affair, and the mother and daughter broke the news that they had turned against each other and abandoned their foster care. During this period, Zhang’s mother also took all Angela Zhang’s savings, which was even more exciting than the dog blood drama.

Angela Zhang’s mother-daughter dispute farce

In the end, Angela Zhang held a press conference to announce that the fate of mother and daughter had ended, but Angela Zhang’s career was affected and plummeted.

Christine avoided the Angela Zhang incident.

When Angela Zhang experienced various changes, the so-called "good sister" Christine not only avoided Angela Zhang, but also poached Angela Zhang’s assistant Lv Danshui. The company also added fuel to the fire and caused a contract dispute.

The two were embarrassed on the same stage in 2010.

In 2010, although they sang the familiar melody again on the same stage, they were embarrassed to overflow the screen.

Christine isLv danshui is unfair.

In 2011, Angela Zhang and Fumao officially terminated their contract, and Christine sent a message for Lu Danshui, the assistant of her husband Chen Jianzhou, insinuating that Angela Zhang was not good to his assistant in Weibo. Although Angela Zhang also fought back, it did not arouse much splash because of the loss of popularity.

Angela Zhang responded.

The tables have turned, and 2015 is like being "lowered" for Christine, which is also the beginning of the collapse of Christine.

Christine is on the small S program.

Christine military parade basks in the baby to recruit black.

After giving birth, Christine was scolded by Xiao S when she was in Kangxi. She and Wu Peici formed a small team to crowd out herself and Da S, which made netizens feel that she was hypocritical and fickle. After digging a grave, she actually tore up the black history of Wu Peici, Christine, and the feud with Angela Zhang. In the same year, Christine also recruited a large amount of Bosnia and Herzegovina powder because she made a blog in the military parade. Afterwards, she responded, and everyone who saw it had to worry about her double business.

Record the same program

And when everyone thought that it was impossible for them to be on the same stage again, last year’s program "Masked Singers Will Guess" let them be on the same stage again. Although there was no confrontation, it was full of gunpowder.

Full of gunpowder

In September 2017, after the broadcast of the program, Angela Zhang wrote: "Everyone should have intimate friends, and the hypocritical world will get sick if it stays for a long time." Many netizens thought this was an allusion to Christine, but Angela Zhang quickly retorted that he was just expressing his feelings and didn’t target anyone. It was also after Angela Zhang made this wave of refutation that the fighting temporarily subsided for a while.

Angela Zhang responded.

It was also the wonderful performance of Angela Zhang in the program that made her return to everyone’s sight after years of silence, and accumulated popularity and popularity for the return. Bazaar Charity Night also seemed to unblock her hot search system.

Angela Zhang; Angela Chang

Recently, Angela Zhang’s wonderful performance in "The Singer" is also remarkable, and her own story sung in the program has caused netizens to dig up her old feud with Christine, so that Weibo in Christine has been cursing.

Weibo, Christine

User message

Christine also posted a blog suspected of responding to netizens’ claims: "With you, my mother is not afraid of anything." But it backfired, and was angered by netizens not to use children as a shield.

Mr. and Mrs. Chen Jianzhou Christine

The war of abuse that lasted for many days summoned Chen Jianzhou to the end, and there was also a hot search for [Chen Jianzhou’s domineering wife] yesterday.

Chen Jianzhou fabo

In the early morning of March 1, he showed a video of his wife Christine’s concert in Weibo and expressed his deep feelings: "I love your kindness and uncontested personality … and I like that even if you are wronged or even maliciously slandered, you never say bad words!"

Netizen left a message insulting.

However, it was abused by netizens, and Chen Jianzhou even launched a "battle" with netizens in his comments.

Chen Jianzhou calls for rejection of cyber violence

And from the early morning to the evening, I am not only busy protecting my wife, but also calling for "rejecting cyber violence."

Christine Weibo lower control review

Also in Christine’s Weibo comment area for control and evaluation maintenance.

Angela Zhang updateMeaningful, Weibo

Just at noon today, when the hot search cooled down, Angela Zhang sent out a meaningful Weibo, which caused a hot discussion among netizens: "Black and white dogs don’t scream for attention. Shh ~ Mom went to work and will come back to see you soon."

Angela Zhang sun-dried dog

The people who eat melons found that this Weibo is not simple … This is a … sun-dried dog. …

　　On the first day of Tesla’s founder and CEO Elon Musk’s arrival in China, Tesla welcomed the benefits.

　　On April 28th, China Automobile Industry Association and National Computer Network Emergency Technology Processing Coordination Center issued the Notice on Testing Four Safety Requirements for Automobile Data Processing, and all the models produced in Tesla Giga Shanghai met the compliance requirements. Previously, Tesla had realized local data storage in Tesla Shanghai Data Center in 2021. In addition, Tesla introduced a third-party authority to audit the company’s information security management system and passed the security management system certification (ISO27001).

　　Musk said on the social platform on April 28 that Tesla will invest about 10 billion US dollars in AI training and reasoning in 2024, and the latter is mainly used for automobiles. If any company can’t reach this level of expenditure and can’t spend efficiently, it can’t participate in the competition.

　　Six car companies, including Tesla, passed all four requirements of national automobile data security.

　　At the invitation of the China Council for the Promotion of International Trade, on the afternoon of April 28th, Tesla founder and CEO Musk arrived in Beijing. Musk said that he was glad to see the progress of electric vehicles in China, and all cars will be electric in the future. On April 28th, Tesla issued a document saying that it will continue to deepen its cultivation in China, develop together with the industry in the fields of artificial intelligence, electric vehicles and energy storage, accelerate the landing of clean energy and autonomous driving technology, and turn the beautiful vision into reality.

　　On April 28th, the Technical Department of China Association of Automobile Manufacturers disclosed the notification on the detection of four safety requirements for automobile data processing (the first batch). According to the report, there are six car companies, including (), Ideality, Lotus, Hezhong New Energy, Tesla and Weilai, and a total of 76 models meet the four compliance requirements for automotive data security.

　　According to the circular, in order to standardize automobile data processing activities, protect users’ legitimate rights and interests, encourage head car manufacturers to play a role as a benchmark, and promote the formation of a good environment for the whole society to jointly safeguard automobile data security and promote the development of the automobile industry, China Automobile Industry Association and the National Computer Network Emergency Technology Processing Coordination Center are based on the "Several Provisions on Automobile Data Security Management (Trial)" and GB/T 41871-2022 "Information Security Technology Automobile Data Processing Safety Requirements" and other laws and standards, and in accordance with the principle of voluntary inspection by enterprises. Since November, 2023, we have organized the inspection of automobile data safety compliance of newly listed intelligent networked vehicles of automobile manufacturers in 2022-2023. This test covers four compliance requirements, such as anonymous processing of external face information, default not to collect cockpit data, in-vehicle processing of cockpit data, and significant notification of personal information.

　　Notice on the Detection of Four Safety Requirements for Automobile Data Processing disclosed by the Technical Department of China Automobile Association

　　Some senior auto industry analysts analyzed the Shanghai Stock Exchange reporter, and this incident released two signals: 1. The state has formulated clear rules for auto data security. 2. All car companies are treated equally before the rules, including wholly foreign-owned car companies. "Obviously, this will help foreign investors to invest in China and further expand their investment in China. At the same time, it also shows that the state has been making efforts to improve the foreign investment environment. "

　　Tesla FSD landing requires data acquisition and other preparations.

　　On April 28th, Musk, who just arrived in Beijing, said on social media that Tesla will invest about $10 billion in AI training and reasoning this year, and reasoning is mainly used in cars. Musk said that any company that spends less than $10 billion a year or cannot deploy it efficiently cannot compete in the market.

　　In January, 2024, Tesla added $500 million in new investment and purchased about 10,000 NVIDIA H100 GPU for the training of autonomous driving. According to statistics, Tesla may have more than 30,000 H100 GPU. Musk recently said that Tesla may be the second company with the number of H100 GPU in NVIDIA, second only to Meta, and xAI ranked third.

　　Tesla’s heavy investment in AI is aimed at the future business opportunities of autonomous driving. Musk said that Tesla will launch a driverless taxi on August 8, 2024. Recently, Tesla gradually began to push to North American users on a large scale based on end-to-end FSD V12. FSD V12 achieves the goal of autonomous driving through a large amount of video training data, which enables Tesla to save hundreds of thousands of lines of code. However, training such AI autopilot requires a lot of computing power. Musk said in August, 2023 that Tesla will soon launch a GPU cluster consisting of 10,000 NVIDIA H100′ s to train the new FSD system.

　　In terms of price, just in April, Tesla lowered its offer for FSD(Full-Self Driving, referred to as "FSD") twice to attract users. Just a week ago, Tesla announced that the price of its FSD system package was lowered by about one-third from $12,000 to $8,000, just after lowering the price of models in the Chinese and American markets. Prior to this, on April 13th, Tesla announced that the monthly subscription price of FSD (supervised) had dropped from $199 to $99, and the subscription price was directly "halved".

　　Musk predicts that Tesla’s FSD test mileage needs to reach 6 billion miles to meet the requirements of global regulators. The data released by Tesla on April 6 shows that the actual test mileage of FSD is 1 billion miles. At present, Tesla FSD has been upgraded to the end-to-end version of V12.3, no longer relying on traditional rule codes, but relying entirely on neural networks and data drivers.

　　According to industry experts, if Tesla FSD lands in China, the data collection, model training and computing center will be regarded as the key. () The research report points out that if FSD is popularized in China, the whole set of closed-loop data needs to be made in China, and preparations should be made in terms of data collection and model training, and whether the BEV sensing scheme can be well adapted locally should be considered. In China, FSD mapping may need to cooperate with China manufacturers, and Tesla needs to set up a local computing center and a local algorithm adaptation team.

　　Us regulators release Tesla Autopilot survey summary report

　　The National Highway Traffic Safety Administration (NHTSA) revealed last Friday that it has started a new investigation into Tesla. The survey covers Model Y, X, S, 3 and Cybertruck vehicles equipped with Autopilot, which were produced in the United States from 2012 to 2024.

　　At the same time, NHTSA has launched an investigation into Tesla’s Autopilot recall in December last year. The agency found that the Autopilot autopilot system could not fully ensure the driver to concentrate on the driving task, and it would lead to the driver’s overconfidence in the function of the system. According to the report, these factors led to foreseeable misuse and avoidable accidents, of which at least 13 accidents involved one or more deaths.

　　NHTSA concluded that there was a "critical safety gap" between the driver’s ability expectation of Tesla Autopilot system and the real ability of the system, which led to a series of avoidable accidents. Tesla conducted a recall of 2 million American Tesla vehicles in December last year, and improved the driver monitoring system of these vehicles through software upgrades.

　　Tesla’s share price closed down 1.11% last Friday, with a cumulative decline of more than 30% this year. Tesla’s previously released financial report for the first quarter of fiscal year 2024 showed that the revenue in the quarter fell by nearly 9% year-on-year, the decline in revenue was the highest in 12 years, and the net profit dropped by 55% year-on-year. The key indicators of the financial report were all lower than expected.

　　According to another report, US Securities and Exchange Commission (SEC) documents show that Drew Baglino, a former senior vice president of Tesla who announced his resignation earlier this month, sold about 1.14 million shares of the company, with a total value of about 181.5 million US dollars. According to the document, Baglino also reduced its holdings of Tesla shares twice this year, with a total value of about 4 million US dollars.

Li Qinfeng, Director of Domain Name Business Department of Domain Name Registration Management Center of Government Affairs and Public Welfare Organizations

With the extensive and in-depth application of information technology, especially the continuous development of e-government, the website of party and government organs has become increasingly prominent. It has become an important window to publicize the party’s line, principles and policies and open government information, and an important platform for party and government organs at all levels to perform social management and public service functions, do things for the people, understand social conditions and public opinion, and accept supervision by the masses. The Fourth Plenary Session of the 18th CPC Central Committee put forward that "network behavior should be regulated according to law", which requires us to institutionalize and standardize the management of online names of party and government organs according to law, so as to ensure that the websites of party and government organs are "be worthy of the name, standardized names, safe operation and healthy development", thus ensuring the safety of websites of party and government organs and institutions.

First, the connotation of website security of party and government organs and institutions

General Secretary of the Supreme Leader pointed out that there is no national security without network security, and it is necessary to strengthen the management of new technologies and applications in the network to ensure that the Internet can be managed and controlled. Internet is a double-edged sword, well used, it is the treasure house of Alibaba; It doesn’t work well. It’s Pandora’s box. The website security of party and government organs and institutions includes three aspects: identity security, integrity security and information security.

One is identity security. In the real world, party and government organs and institutions have their own office space, which can only be listed, publicized and provided with services for the public after being examined and approved by the establishment departments at all levels in China, so its identity is well known to the public and is safe and reliable. However, in the virtual space of the Internet, in recent years, criminals posing as party and government organs and institutions have frequently set up fake websites, which has had a bad influence on the authoritative image of party and government organs and institutions and also caused losses to the public. Therefore, the identity security of party and government organs and institutions on the Internet needs to be guaranteed, so that the public can clearly identify them and will not be deceived by fake websites.

The second is integrity and safety. With the development of the Internet, the public can obtain government information and communicate with the government online in real time. The government can also contact the public synchronously, instantly, trans-regionally and trans-temporally through the Internet, and feedback the public’s demands for the government at the first time, thus effectively conserving, maintaining and cultivating the people’s trust in the government. However, due to various reasons, a large number of news in the name of the government have been published and reprinted on the Internet, and the public can’t tell whether these news are true or false. Some rumors confuse the public and even cause group incidents, which is not only detrimental to the long-term stability of society, but also directly damages the integrity and authority of the government.

The third is information security. At present, the websites of party and government organs and institutions have become an important platform for policy release and interaction between the government and the people, and at the same time, they have also become the carrier of public personal information because of the public’s online business. The Internet is logically divided into three layers. The first layer is the basic layer, including bandwidth, IDC computer room and mobile interconnected base stations. The second layer is the basic resource layer, including domain name, IP and so on; The third layer is the application layer, including mail, website, application system and so on. Among them, the second layer represented by domain name is the key to information security risks. If the Internet is likened to a highway, the second floor is equivalent to signs and cameras on the highway. If the highway of China’s Internet is guided by English signs and monitored by foreign cameras, then security can certainly not be guaranteed. Therefore, if Chinese government websites use commercial domain names, each parsing data will be reflected in the root server of this domain name, which will be mastered by foreign countries. Once the website has security risks, the public’s personal information will not be guaranteed, which directly threatens China’s network information security.

In a word, it is very important for party and government organs and institutions to ensure the safety of their websites. This requires that the identity of the websites of party and government organs and institutions can be confirmed, the voice can be distinguished, and the information can be guaranteed.

Second, how to ensure the website security of party and government organs and institutions

Online name management refers to the four-in-one comprehensive management with the use of online names and online identity identification of party and government organs and institutions as the core and domain name registration, website audit, website labeling and annual report as the main contents. Through the monitoring, retrieval, identification and protection of the online identity of institutions, it is widely used in various platforms such as Weibo, WeChat and browser, and finally makes the online identity clearer, the network environment clearer and the online business more secure.

(1) Domain name registration

According to the Interim Measures for the Administration of Online Names of Party and Government Organs, Institutions and Social Organizations (hereinafter referred to as Document No.6) jointly issued by the Central Committee and the Ministry of Industry and Information Technology, party and government organs and institutions must register and use standardized Chinese domain names for ".government affairs" or ".public welfare". These two Chinese domain names are technically unique, highly recognizable in form and strictly managed by the organization’s establishment department, which makes them qualified as "online identity cards" for organizations, and also makes Chinese domain names the premise and core of online name management.

(2) Website audit and website labeling

In May 2014, the Central Network Information Office issued the Notice on Strengthening the Website Safety Management of Party and Government Organs (hereinafter referred to as Circular No.1), which clearly required the organization department to be responsible for the website start-up audit and qualification review of party and government organs, and to design and formulate the usage norms of website logos of party and government organs.

Website labeling refers to placing a unified website logo in a prominent position at the bottom of the website after the websites of party and government organs and institutions are approved by the organization department. Clicking this logo will display the basic information of the company and the online name, etc., so as to facilitate the public to distinguish the authenticity of the website.

(3) Annual report

According to Circular No.6 and the Notice on Doing a Good Job in Auditing, Qualification Review and Website Logo Management of Party and Government Organs’ Websites (hereinafter referred to as Circular No.69) jointly issued by the Central Editorial Office and the Central Network Information Office, online names and website logos are subject to a regular reporting system, and website owners should regularly report online changes in their qualifications, the use of online names and website logos to the organization establishment department.

Third, the significance and necessity of online name management.

(1) Why is the organization department responsible for the management of online names?

The organization establishment department holds the most accurate information of organization identity and name, and is managed by the organization establishment department, which can effectively ensure the "be worthy of the name and standardized name" of party and government organs and institutions on the Internet. Therefore, as early as 2008, the Ministry of Industry and Information Technology clearly stipulated that Chinese domain names for government affairs and public welfare should be managed by the organization department. In 2014, in the No.1 document issued by the Central Network Information Office, it was further stipulated that the organization preparation department was responsible for the audit and qualification review of the website of the party and government organs, and designed and formulated the usage norms of the website logo of the party and government organs.

(2) Why should we register and use standardized Chinese domain names?

Chinese domain names for government affairs and public welfare conform to the language and cultural habits of Chinese people, and can clearly reflect the name and functions of institutions, similar to the "online ID card" of institutions. For example, the Chinese domain name compiled by the central government is "Central Compilation. Government Affairs". Compared with its English domain name "scopsr.gov.cn", the Chinese domain name is clear at a glance, which not only embodies the authoritative identity of the organization, but also facilitates public recognition and memory, and is the basic guarantee for netizens to surf the Internet safely and do things with confidence.

Fourth, the significance of establishing an online ID card authentication and protection application system with Chinese domain names as the core.

The first is to maintain authority. It is an important means to maintain their authoritative status in cyberspace to put on "anti-counterfeiting clothes" for institutions by standardizing online names and hanging website logos. The second is to make it safer to do things online. Marking the identity information of the organization on the Internet makes it easy for netizens to distinguish the true and false websites of the organization, which can improve the efficiency and facilitate the work on the Internet. The third is to ensure national information security. Party and government organs and institutions are the core political resources in China, and their information security on the Internet is particularly important. Strengthening the authentication and protection of its online identity can effectively guarantee the security of the country’s core information. The fourth is to make the organization management more scientific. Through website logo management, we can fully understand the online performance of institutions and provide scientific reference for the performance evaluation and management of institutions.

We maintain the seriousness and authority of the websites of party and government organs and institutions, protect the safety of the websites of party and government organs and institutions, and establish a green channel for the public to visit the websites of government departments and public welfare institutions quickly and accurately, so as to promote the popularization of Internet application and the development of government affairs openness and e-government in China.

　　Judging from the current situation, portable Bluetooth stereos are small and portable, supporting Bluetooth and voice calls, and some products even add mobile power or even intelligent voice prompt design, which makes the selling point of products more prominent. At the same time, we found that the established speakers such as rambler and Sannuo have not set foot in the field of portable Bluetooth audio, but prefer to integrate Bluetooth functions on the basis of existing products. On the contrary, many micro-audio manufacturers are in the middle of this "gold mine" and are planning to enter the market as quickly as possible to seize the share. In the near future, this market will definitely become more lively and chaotic. We hope that the portable Bluetooth audio market will not repeat the micro-audio.

　　China news agency, Beijing, May 13 th The National Development and Reform Commission of China reported on the 13th that the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development had compiled the "Development Plan for Urban Domestic Waste Sorting and Treatment Facilities in the Tenth Five-Year Plan". According to the plan, by the end of 2025, the classification and treatment capacity of domestic waste in 46 key cities, including municipalities directly under the central government, provincial capital cities and cities with separate plans, will be further improved; A domestic waste sorting and treatment system has been basically established in prefecture-level cities according to local conditions.

　　This plan puts forward three specific goals: by the end of 2025, the utilization rate of municipal solid waste resources in China will reach about 60%; By the end of 2025, the capacity of classified collection and transportation of domestic waste in China will reach about 700,000 tons per day, which basically meets the needs of classified collection, classified transportation and classified treatment of domestic waste in cities at prefecture level and above; By the end of 2025, the incineration capacity of urban domestic waste in China will reach about 800,000 tons per day, and the incineration capacity of urban domestic waste will account for about 65%.

　　In the past five years, 46 key cities in China have carried out domestic waste sorting, demonstration and guidance, and the coverage rate of residential areas has reached 86.6%, and basically established a system of domestic waste sorting, collection, transportation and treatment. The national domestic waste sorting collection and transportation capacity is about 500 thousand tons per day.

　　However, the plan also points out that at present, there are still some problems such as insufficient treatment capacity, unbalanced regional development, hidden environmental risks of existing landfill facilities, and imperfect management system and mechanism.

　　This plan puts forward ten main tasks, including: accelerating the improvement of waste sorting facilities system, comprehensively promoting the construction of domestic waste incineration facilities, orderly developing the construction of kitchen waste treatment facilities, standardizing the construction of waste landfill treatment facilities, improving the recycling facilities of recyclable materials, strengthening the sorting and treatment of harmful waste, strengthening the capacity building of secondary environmental pollution prevention and control of facilities, carrying out key technology research and development and pilot demonstration, encouraging the coordinated disposal of domestic waste, and improving the capacity building of monitoring and supervision in the whole process.
