Flexible sensor material sample diagram

　　A flexible sensor with a thickness of 200 microns (one tenth of the normal blood vessel thickness) is made of a special force-electricity conversion biomaterial and wrapped around a blood vessel or a heart, so that the subtle changes of the whole body blood pressure of the cardiovascular system in the early, middle and late stages of thrombosis can be clearly recorded on peripheral devices such as mobile phones, and at the same time, the slight differences of the cardiovascular wall pressure caused by the alienation of tissues and cells at the initial stage of the disease can be reflected more accurately and in real time.

　　The reporter of Science and Technology Daily recently learned from Nanjing University of Science and Technology that Professor Feng Zhangqi’s research group has created a new method for advanced prediction and real-time follow-up of cardiovascular diseases by monitoring the changes of micro-stress outside the cardiovascular wall. At present, the research group has made phased technological breakthroughs and completed the evaluation of animal clinical medicine. Related research was recently published in American Chemical Society-Nanomaterials and Devices, a top international journal in the field of nanotechnology and nanodevices.

　　New Nano-materials for Efficient Biomechanical-Electrical Conversion

　　Cardiovascular disease is the "number one killer" threatening human health, and whether the blood vessels are unobstructed is related to the normal operation of the whole cardiovascular system. Thrombosis is a small piece formed by blood flow on the surface of the inner surface of a blood vessel where it is peeled off or repaired. In the variable fluid-dependent type, thrombus consists of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells.

　　Experts say that "advanced prediction" and "real-time follow-up after operation" of cardiovascular diseases are the key points for effective clinical diagnosis of such diseases, especially for patients with severe cardiovascular diseases such as vascular tumor resection, intracardiac stent, valve, vascular replacement and intravascular stent. However, the existing molecular screening and imaging techniques lack accurate specific recognition function, which makes the advanced prediction and real-time tracking of cardiovascular diseases become a worldwide technical problem in clinical diagnosis and treatment.

　　Feng Zhangqi’s research group has long been committed to the development of bioelectronic materials and nano-devices, trying to build a new method for advanced prediction and real-time tracking of cardiovascular diseases by monitoring the changes of micro-stress outside the cardiovascular wall.

　　According to Dr. Li Tong, the first author of the paper, this time they pioneered a flexible nanofiber material with high-efficiency biomechanical-electrical conversion performance. Its thickness is only 200 microns, and it can accurately sense the pressure change and then show it in the form of voltage.

　　The material is rich in electromechanical conversion dipoles, which can generate a voltage of 1154 volts per cubic centimeter under the action of only 1000 Pascal, and has excellent stability, sensitivity and biocompatibility.

　　After being implanted in the body, the cardiovascular system can be monitored in real time through the mobile phone.

　　Based on this, the research group designed and manufactured a flexible implantable pressure sensor. They implanted the sensor into the peripheral blood vessels and heart parts of experimental animals (adult pigs), which not only clearly recorded the subtle changes of systemic blood pressure in the cardiovascular system at the early, middle and late stages of thrombosis, but also output a more accurate pressure signal, reflecting the slight difference of cardiovascular wall pressure caused by tissue and cell alienation at the initial stage of the disease in real time.

　　"Normal people’s blood pressure is beating with frequency, but when some tissues or cells are alienated in blood vessels, a fluctuating signal will be generated on the detector, no matter whether it is getting bigger or smaller, it is disordered. Once we detect this disordered signal and it doesn’t match the signal stored internally, we will issue some warnings, indicating that blood vessels may have problems." Feng Zhangqi said.

　　In the future, the flexible sensor can be implanted in the body together with cardiovascular surgery. Through the introduction of wireless signal transmitter, medical staff can track and diagnose the pathological changes of patients’ cardiovascular system in real time at clients such as mobile phones.

　　Feng Zhangqi explained: "We can convert it into an electrical signal that can be output by remote sensing. In the future technology, we can transform it into a signal received by a mobile phone. After receiving the signal, the mobile phone can share this signal with the hospital, so that it can be monitored remotely in real time."

　　At the same time, the successful development of this ultra-sensitive flexible implantable pressure sensor also provides a new method for accurate detection of micro-stress in vivo, which has great technical promotion for clinical real-time and accurate measurement of craniocerebral pressure, renal pressure and intraocular pressure.

　　[car home New Car Launches] On August 16th, the pagani Roadster was officially released at the Pebble Beach Auto Show, with the same power configuration as the hardtop version, with a global limited edition of 130 V12 engines and an overseas price of 3.4 million US dollars, about 24.654 million yuan.

　　Although the new car is a convertible version, the net weight of the car body is the same as that of the hardtop version, both of which are 1280 kg. The design of the convertible structure part is ingenious, and it can be completely disassembled with a skylight. Not surprisingly, the new car adopts carbon fiber single shell body, and continues the traditional design of butterfly door with upward folding, which is highly recognizable. The front engine room cover is smooth without too many curves. The headlight group continues to adopt the traditional double-willow shape, and the interior decoration part of the headlight also uses carbon fiber. In addition, the air inlet of the front face is designed to be large, which makes the new car have strong heat dissipation ability.

　　The rear half of the car body uses an integrated rear cabin cover, and there is an observation window at the engine, so you can enjoy the V12 engine from AMG at any time. In the rear part, the classic central four-outlet exhaust pipe divides the color matching spoiler into two parts, and the taillights on both sides are arranged vertically. The overall hollow shape of the rear part is obvious and very layered.

　　The interior continues the style and layout of the pagani supercar interior. There is no central control electronic screen, all physical buttons are decorated with a circle of blue lights, and almost all parts of the car are covered with leather or carbon fiber panels.

　　In terms of power, the new car is still equipped with a 6.0T twin-turbo V12 engine provided by AMG, with a maximum power of 864 HP and a peak torque of 1,100 Nm. The transmission system is matched with Xtrac 7-speed sequential gearbox, and manual transmission is also optional. In addition, the new car will be equipped with active suspension and innovative sensor system of Pirelli Cyber Tyre, which can monitor the status of Pirelli P Zero Corsa, Winter and Trofeo RS tires and transmit the real-time tire information back to the on-board computer, so as to regulate the traction control system, which can control the stability of the vehicle more accurately, thus exerting stronger performance potential under the premise of safety.

The Hobbit: The Battle of the Five Armies is being shown in China, The Avengers 2 and Star Wars 7 are ready to go, and the domestic blockbuster Sima Migration 2015 has come to an end. We don’t know yet whether the series "shoots a sequel"; We also don’t know the specific identity of the director "The Little Soldier". On the evening of January 23rd, local time, Si Manan unveiled the mystery of the "immigration situation" at the North American Chinese Spring Festival Gala on International Satellite TV (ICN), and released several photos of him as a guest at this Spring Festival Gala through Weibo. The irascible old man Sima laughed at himself in Weibo: "Why did Si Manan become Sima Yi?"

The finale of Sima Immigrants 2015

Si Manan expressed his thanks to Observer.com for paying attention to this series of events by voice. He also told Observer.com that he originally wanted to clarify this online rumor two days in advance, but the television station (ICN) thought that it would be better to have such an opportunity to explain it on the spot under the witness of many important American media, and he himself agreed to this arrangement. An interview session was added to the "Happy Spring Festival North America 2015 Hollywood China New Year’s Party", which allowed Si Manan to answer three questions: one was his personal immigration problem, and the other was the reason why he landed on North American TV as the host of China to make the program "Sima Vernacular"; Third, the differences between Chinese and American folk festivals.

Si Manan responded in Weibo.

How did this farce end? Si Manan has just recorded some live conversations through the long article "My Explanation (Part II)-Sima Yi (Shift) Phenomenon" published by Weibo. This article not only discriminates and refutes rumors, but also raises thoughts on Sino-US relations and the management of personnel exchanges between China and the United States. The excerpts of Observer Network are as follows:

Tonight, celebrities from all walks of life in the United States and Los Angeles gathered together to dress up for the 2015 North American Chinese Spring Festival Gala.

In front of the officials of the China Embassy and Consulate, in front of 600 or 700 live audiences, in front of major media reporters, Mr. Jason, a famous TV presenter, asked sharply: "I heard that Mr. Si Manan also immigrated to the United States?"

A: "No."

"Really? How did I hear that you immigrated to America? "

A: "I have never immigrated, and I don’t intend to immigrate. My family has not immigrated … I think it’s good to be Chinese."

The audience gave me warm applause. "Of course, I’m not saying that immigration is not good." (Laughter and applause)

"Then where did you do your talk show? What are you doing in America? "

"The talk show" Sima Vernacular "broadcast by lCN International Satellite TV in the United States was recorded in Beijing. I came to the United States this time to participate in the North American draft of China CCTV Avenue of Stars and served as a judge in new york and Los Angeles."

The live photos of Weibo, the old man, are almost all taken with beautiful women at home and abroad, which is very embarrassing.

I asked Jason, "What did you just call me?"

Jason suddenly froze. He was a little uncertain and hesitated to say, "Did I say something wrong? Your name is Si Yima Nanyi, right? "

"Oh, Si Manan, that was my previous name. Now I’m going to change my name to Sima Yi. Do you know why?"

Jason is a clever boy, and he has come to his senses. "Oh, I know, I know, you are talking about the migration of immigrants."

"Yes, in the past few days, people have said that Si Manan has immigrated, and they have a nose and eyes. I don’t care about this repeated immigration. I am afraid that the officials of the US Immigration Bureau can’t stand it. They are bored!"

The audience laughed and laughed happily.

"What’s the rating of your program Sima Vernacular?"

"The program" Sima Vernacular "was originally rated well, because it is a daily broadcast program closely related to current politics, and it is broadcast on time at nine o’clock every night, plus two reruns, which is an original talk show with high density. Recently, rumors about Si Manan immigrants have been constantly fermented on the Internet, which has caused more people to care about Sima vernacular, and the ratings have been unexpectedly greatly improved.

"Your question reminds me of something I experienced before Linlai. This time I came to the United States for a face-to-face interview, the visa officer asked me about my occupation, and I said that I was a TV presenter. He asked,’ What program is hosted?’ I said,’ In the United States, ICN International Satellite TV hosts the program "Sima Vernacular." He looked at me and then asked,’ Your name is Si Manan, and your program is called Sima Vernacular … Is this program good?’ I can’t boast that the program is good, which is suspected of selling melons. So I replied:’ Let’s put it this way, as a visa officer, it would be a great pity if you didn’t read it.’ The visa officer said,’ OK, I’m going back to see it now. If it doesn’t look good, I’ll cancel your visa! Then he gave me the visa with a smile.

"In this way, I got a visa to the United States valid for ten years …"

I am grateful to my friends for their concern about my emigration to the United States. Some people support my emigration to the United States, some people make rumors that I have emigrated to the United States, some people believe the rumors, and on the basis of the "facts" woven by the rumors, many irresponsible and even personal attacks are made. Because the premises on which it is based are all false, these wonderful arguments are naturally untenable.

The 2015 Chinese Spring Festival Gala in North Si Manan is a multicultural carnival. I am grateful to the organizers for giving me an opportunity to personally clarify the various rumors about "immigrants" that have been fermenting on the Internet in recent days.

……

The fact is obvious. Whether Cui Yongyuan, Ren Zhiqiang and other people involved in making and spreading rumors about Si Manan’s immigration to the United States admit their mistakes has little influence on the fact itself and Si Manan himself. There is only one possibility to insist on not admitting mistakes and let people see through the shameful things behind their beautiful moral robes.

Sino-US relations are the most important bilateral relations in the world. One is the largest developed country, and the other is the largest developing country. The top leaders of the two countries have proposed that in order to establish a new type of relationship between major powers, there are both common demands, common interests and common concerns in the relations between the two countries, and there are different development orientations and value orientations, so stumbling is indispensable.The exchanges between the two countries, including personnel exchanges, are an important aspect of close relations between new powers. Freedom of movement of citizens is an extremely private topic on the premise of abiding by the laws of the two countries.

Some well-known people in China who are bent on crashing into a wall and sinking a ship have selectively politicized the immigration issue and violently kidnapped it. Obviously, when they ganged up to attack their political opponents, they completely ignored the facts and fabricated them at will, forgetting the moral golden rule of not doing to others what they want them to do. In this way, the moral bankruptcy is not the object of their attack, but just themselves.

Some people are curious, why do those people smear you every day?

It’s a long story for a child without a mother. You will know how many people I have offended in the Jianghu if you look at my writing for more than 20 years. How many people have I offended on political and ideological issues? I am different from those "enlightened gentlemen" who cherish feathers within the system. For those who slander China’s fundamental political system, Si Manan is a heinous and vicious enemy, because he is a sniper who jumps out of the trenches and fights with open flames.

Facts need to be clarified, and after all, facts speak louder than words. Clarified facts speak louder than words, which will help convince those who are in the middle. However, for those who have lost face again, this move will only arouse a new round of even crazier roar and resistance.

Observer Network has never given up its efforts to find "That Little Soldier". According to Xiaobian’s latest discovery, his more specific and reliable identity is a columnist of "BWCHINESE Chinese Network", and the actual meaning of "That Little Soldier" is to compare himself with Lei Feng and hope to become a "soldier like Lei Feng". The brief introduction of "The Little Soldier" column "Economics of Human Nature" is as follows:

When economics becomes gambling, it loses common sense and conscience instead of skills and patterns. As a folk "economist", what I expect is to share my feelings, sadness and joy, expectation and disappointment with the public, which is much more meaningful than the author’s American famous degree. That little soldier is here to prove that he is indeed a soldier like "Lei Feng in Economics" in this era.

　　An American amateur photographer recently captured a group of spectacular photos of the moon mirage in casco Bay, Maine. This rare astronomical phenomenon is called "Etruscan vases" by French science fiction writer jules verne. The reason for its formation is that layers of air at different temperatures bend the moonlight.

　　When light passes over the boundaries of different air layers, the moon in front of us will be deformed, creating the illusion that the second moon is tightly attached to the first moon. A few minutes later, the two moons separated, and the slightly lower "moon" slipped into the sea again.

　　After a full morning of sunshine, the sea surface began to heat up in the afternoon. Under this condition, an abnormal air layer with high temperature appeared and floated on the sea surface. On the day of this group of photos, the surface temperature of seawater reached 4 degrees Celsius, while the air temperature above the sea surface was only MINUS 8 degrees Celsius. When the light of the full moon hit the boundary between this cold and hot air layer, the path of the light would be deformed and refracted. So the illusion of a second moon appeared.

　　This phenomenon is similar to the illusion caused by puddles on the road in high temperature weather. Physicist Dr. Liz Cowley said: "The photo was taken in the evening. Under the irradiation of sunshine for a day, the sea water heats up, which makes the air temperature above the sea surface rise. Once the air in different layers has a temperature difference, the normal orbit of light passing through them will be deformed, which will produce this illusion. " He explained that the moon was blood red at that time, probably because the blue wavelength of light absorbed by the atmosphere was short, which allowed red light to pass through.

　　This also cuts the robe, and that also breaks off diplomatic relations. Siraj Raval, the online celebrity of AI, has really become a street rat this time.

　　Moreover, many of them are well-known big names in the industry.

　　After MIT professor Lex Fridman deleted all the content about Siraj from his social media, Jeff Dean, the head of Google AI, also publicly announced that he would take Siraj Raval.

　　Douglas Eck, the chief scientist of Google Brain, took the lead in calling for: this scum, criticize him and take him away!

　　Rachel Thomas, co-founder of fast.ai, regrets it even more:

　　I interviewed Siraj Raval, and it’s a stain on my life.

　　Who is Siraj Raval (Siradj Laval) who was torn by a group of bosses?

　　He is a well-known broadcaster of YouTube, and his AI network course is very popular abroad. If we want to make an analogy, his popularity in English AI online class is just like that of Li Xiaolai in the currency circle.

　　Now, however, the online celebrity native’s design is crumbling. Not only is the paid online course accused of cheating money, but the published paper is also naked plagiarism-all by Ctrl+C and CTRL+V..

　　Before being accused of "cheating money", Siraj still kept his face straight, skipped live as usual, and publicly quoted his own paper.

　　However, unfortunately, Andrew M. Webb, a researcher at Manchester University, took a look at it-is it too insulting to copy and paste the paper like this?

　　Later, the drums broke through thousands of people, and more netizens came off the scene to reveal that Siraj, online celebrity, had no underwear left today …

　　△ skinned stickers reddit heat 2000

　　It is also considered that AI is too hot, and mud and sand are everywhere. Siraj shattered the three views of the AI ? ? community with his own efforts.

　　A popular online class

　　How hot is Siraj? Just look at his former followers: Jeff Dean, Ian Goodfellow, Fran? Ois Chollet… … (All have been cleared)

　　I graduated from Columbia University with a bachelor’s degree (questioned by netizens as a dropout). In 2016, I started uploading artificial intelligence and blockchain related courses on YouTube. Siraj used this style of painting-

　　△ sing rap

　　Known as the strongest Rapper in the AI world.

　　He also founded the School of AI, an AI learning community, and called it a non-profit organization, aiming to provide world-class AI education for anyone on the planet.

　　It is said that more than one million students have seen his online class. And every project he has on GitHub has thousands of stars.

　　△Siraj Raval part GitHub project

　　Three months to learn data science, six weeks of intensive learning … Almost every course is under the banner of rapid learning.

　　Moreover, talking about learning AI to make money is just a title of "The Road to Wealth and Freedom".

　　Because of this resume, eloquence and ability to fool, it was really followed at first, and the business prospects were bright.

　　However, after he launched the charging course Make Money with Machine Learning, Siraj got into trouble.

　　People set a fuse for collapse: using knowledge to pay for cheating money

　　What got Siraj in trouble was an online course he offered, "Making money by machine learning".

　　Just by listening to the name, you can know that this is a knowledge-paid online course that netizens love to see, but the price is not close to the people at all, and it is much more expensive than ordinary courses in Udacity and Coursera. After all the courses are completed, you have to pay 199 US dollars, equivalent to nearly 1300 yuan.

　　He also claimed that his energy was limited, and in order to focus on a few students, he was limited to 500 people.

　　Even so, according to this limit, this course can earn him $100 thousand.

　　Of course, with Siraj’s high popularity, it is definitely not a problem for the course to be full.

　　But the tricky thing began to be exposed.

　　The paid students later found that Siraj not only did not build an exchange group for the course, but also found that some students could not contact each other at all when they tried to communicate through the chat software Slack.

　　This is naturally intentional.

　　Siraj actually adopted the method of building a group in batches, and recruited a total of 1200 students before and after, that is to say, in the name of "limited" marketing, taking advantage of the information gap and secretly expanding enrollment, with the aim of making as much money as possible.

　　Students who know the truth are angry because of "false propaganda", and they also find that the quality and commitment of the course are just like the propaganda at the time of registration.

　　One of the important things is personalized help, which is completely broken.

　　Siraj just released a 30-minute video course every week and gave everyone a question-and-answer period. What about focusing on a few students?

　　More ironically, students find that the course content can be found for free on GitHub … What’s more?

　　Holding something that is free and open source, and then deleting the license to claim originality to make money, itself violates the spirit of the open source community and is despised by the majority of programmers.

　　As a result, students have asked for a refund and dropped out of class, and the momentum is growing.

　　But how can Siraj, who has a good fortune, easily let go of the meat in his mouth? He moved the students to Discord, another chat software, and set up a special program. All messages containing the word "refund" were deleted.

　　If someone goes to his YouTube or Twitter to reply and ask for a refund, Siraj will always black them out.

　　Siraj then added a refund policy to the website, but the requirement is that the refund must be completed within 14 days after registering for the course.

　　However, this obviously violates California law, because consumers have the right to ask for a refund within 30 days.

　　In the end, Siraj couldn’t stand the huge pressure of netizens’ public opinion, or it may be because he was worried about taking a lawsuit. After weighing it again and again, he announced that students who were dissatisfied with the course and paid within 30 days could provide a full refund.

　　Of course, after this battle, the online celebrity people’s establishment collapsed.

　　Lex Fridman, a teacher and researcher at MIT who had been "pink" Siraj before, was also found by netizens last week to quietly delete all the recommendations about Siraj.

　　The paper was found to be plagiarized at pixel level.

　　However, things are not over yet.

　　What completely collapsed Siraj’s design was that he copied other people’s academic papers at pixel level.

　　Below this post, a netizen said that Siraj’s liar nature had long been discovered, especially from his "Neural Qubit" video. In this video, he just summed up the results of Nathan Killoran’s paper and added some subjective and controversial biological theories, but claimed to be his own research.

　　Even the code he posted to GitHub just copied and pasted other people’s versions, and deleted the license and changed some constants.

　　Yesterday, someone even analyzed the differences between Siraj and Nathan Killoran in detail on Twitter, which was equivalent to convicting Siraj of plagiarism.

　　It can be seen that Siraj is almost a piece of plagiarism. The charts, formulas and even symbols used in the two articles are exactly the same.

　　Even careful netizens found that Siraj’s plagiarism can be described as "true pixel level", that is, really taking screenshots.

　　Generally, people who do academic writing will use LaTeX to edit formulas, but the resolution of formulas in Siraj’s paper is actually lower than that in the original paper.

　　Yes, the chart in his paper is so vague. A reasonable explanation is that he just copied and pasted the pictures in other people’s papers.

　　Maybe even "washing the manuscript" feels laborious.

　　Of course, some people say that maybe Siraj doesn’t know LaTeX at all, his college grade is B, and he hasn’t attended graduate school, so he doesn’t have the ability to write professional academic papers.

　　But even if you can’t LaTeX, this plagiarism is too careless. Undergraduate students encounter poor resolution when pasting formulas, and they also know to edit in Word instead of pasting pictures directly.

　　No wonder some people commented that this is simply a plagiarism of Ctrl+C and Ctrl+V levels.

　　Siraj apologizes for his resignation.

　　It is not very nice to say that the expansion of Siraj online courses is just a "just meal" gesture, but copying academic papers and open source code is equivalent to being sentenced to death in the circle.

　　Many big names who had paid attention to Siraj have said that they have cancelled their attention, including Google legend Jeff Dean.

　　An AI enthusiast said that Jeff’s statement is very important. Many people can avoid Siraj’s scam when they see Jeff taking the customs.

　　Siraj saw the momentum, too, and never carried it again.

　　After experiencing a rare silence, in the face of all kinds of evidence dug up by netizens, Siraj finally apologized on his Twitter a few hours ago and deleted the paper suspected of plagiarism on the whole network.

　　However, some people are still kept in the dark, such as the European Space Agency, and even invited him to give a speech at the event.

　　It’s just that there were as many fans as there were at the beginning. Enthusiastic netizens volunteered to set up an "anti-flicker consultation hotline" and sent an email to the European Space Agency, saying that Siraj’s academic ethics was questioned and called for a boycott of his speech.

　　It is also worth noting that Siraj has never forgotten to come to China to collect money over the years.

　　Last year, the domestic blockchain community invited it to cooperate with it, and even called it "Jesus in the machine learning world."

　　Of course, it is not without clues that Siraj misbehaves now.

　　However, because he had a high reputation in the field of machine learning before, and he was too good at marketing, the previous accusations of netizens about his money did not form a momentum.

　　Moreover, Siraj was recognized at first, and it did have something extraordinary. After all, in this field, lively and diverse lecture forms are really unique.

　　However, the motivation is impure, breaking through the bottom line of academic ethics, and trying to make money by using the information gap. In the end, people will inevitably bring about their own destruction.

　　In short, you have to pay it back sooner or later.

　　Fraud in the field of AI will sooner or later be hanged. Right?

All relevant units:

　　Recently, after two consecutive cases of positive people were detected in the building where a socially infected person was located in this city, the basic information of all company personnel in the building was not provided, resulting in that the infected person was not required to be isolated at home, but only worked at home. Because the infected person has a trajectory of social activities, it has triggered the risk of social communication. It reflects that there are still some problems in the epidemic prevention and control work of some units, such as unclear base, untrue data and inadequate implementation of responsibilities. In order to further compact the responsibility of the four parties, strengthen the awareness of epidemic prevention, and shoulder the responsibility of epidemic prevention, according to the latest deployment requirements of epidemic prevention and control in the city, the basic ledger and management of personnel in industrial and software information service enterprises in the near future are emphasized as follows:

　　First, strengthen the management of basic information ledger

　　All industrial and software information service enterprises should learn a profound lesson, thoroughly find out the base number of employees (including all kinds of hourly workers, short-term workers, temporary workers, interns, outsourcing, labor dispatch, maintenance, security, cleaning, canteens, related security personnel, etc.), and establish and dynamically update employee basic information accounts (including core information: personnel name, ID number, mobile phone number, detailed current address, family contact, etc.); Optional information: building layout, tenant distribution and contact information of this unit, seat distribution of all personnel’s office space, personnel’s business trip, recent nucleic acid detection, unit gathering activities and meeting organization, visitor record, etc.), and register all kinds of visitors to ensure that the source can be traced and the destination can be traced.

　　Second, make good use of personnel nucleic acid comparison register

　　Adhere to the principle of "all examinations should be carried out" and "all examinations should be carried out", and strengthen the management, tracking and supervision of personnel’s nucleic acid detection. Each industrial enterprise should designate a person to be responsible for strengthening the epidemic prevention management of its staff by using the nucleic acid comparison register, do a good job in information collection and dynamically maintain the register; In addition to regular employees, temporary employees, new employees and related service personnel should also be included in the management scope, and those who leave their jobs should be eliminated in time; It is necessary to promptly urge relevant personnel to carry out nucleic acid testing in accordance with the regulations, effectively control the "entry barrier", prevent risk personnel from entering the place of resumption of work and production, and build a strong internal "firewall" for enterprise epidemic prevention. All districts should check the register in time and urge and guide enterprises that fail to carry out relevant management work as required to carry out testing as required.

　　Third, timely cooperate with the flow adjustment to share the information ledger.

　　Implement the "four early" requirements, once an epidemic situation occurs, find out the risk personnel and points as quickly as possible, truthfully provide the basic information of the full-caliber personnel of the unit, cooperate with the work of tracing the source of flow, screening for landing, investigation and control, and resolutely prevent the leakage of people and the loss of control. If there are home office workers, we should adhere to the principle of "who manages and who is responsible", make overall plans for the specific arrangements and education management of employees’ home office, urge their employees to implement the requirements of community epidemic prevention, report their personal health status and activity track daily, and strictly prevent leakage of management.

　　Four, strictly implement the requirements of normalized nucleic acid screening.

　　Do a good job in the normal nucleic acid detection and screening of "people, things and environment" and regular detection and screening of key departments, key populations and key areas. For 34 key groups such as cold-chain cold storage, imported non-cold-chain goods and security guards, which are involved in the fields of industry and software information services, we should carry out all-out inspection, and carry out nucleic acid testing according to the requirements of their respective industries, including cold-chain cold storage employees once a day, imported non-cold-chain goods employees, security guards and canteen employees once every two days, and other stakeholders with wide contacts should also encrypt the frequency of nucleic acid testing, so as to gain time for finding the epidemic risk at the first time and effectively handling it.

　　I hereby inform you.

　　As the saying goes, "a thousand dollars can’t buy old people to lose weight." Nowadays, many old people have joined the army to lose weight, and it seems that they will be healthy if they lose weight. Recently, a study published in the American Obesity magazine shows that the elderly’s deliberate weight loss may affect their bone health.

　　Body mass index BMI= the square of weight/height, which is an accepted standard to measure obesity. In this study, 77 students with an average BMI of 33.6 (usually 18.5≤ BMI index ≤ 23.9 old people with normal weight, more than 29.9 are severely obese) were given weight-loss intervention for 18 months, and the overall weight of the old people and the bone mineral density of the areas (total hip, femoral neck, lumbar vertebrae and trabecular bone) were monitored and scored at 18 months and 30 months. The results show that the decline of hip bone mineral density will last for one year after weight-loss intervention for elderly obese patients, whether they rebound or not. The study also found that fat loss and weight loss reduced the bone mineral density of hip and increased the risk of osteoporosis.

　　Gou Bo, a professor in the Department of Health Sciences of Xi ‘an Institute of Physical Education, said that if the elderly lose weight improperly, such as excessive diet control, resulting in insufficient nutrition intake, or lose weight too much and too fast, resulting in significant weight loss, it will lead to a decline in bone density. Older people do not have to lose weight if they are only slightly obese and have no obvious cardiovascular disease. If there are some contraindications to exercise, and it is not suitable for exercise to lose weight, you can seek nutrition, medical care and other methods to control your weight under the guidance of a doctor. If obesity is accompanied by other chronic diseases, lose some weight appropriately. In principle, adopt safe and effective methods to achieve the goal at a slower speed such as diet control and exercise.

　　Many old people find that even if they eat and exercise as much as when they were young, it is easy to "gain weight". The reason is that the basal metabolic rate and muscle mass of adults decrease year by year with age. Therefore, even if the elderly eat less, their digestion and absorption ability are poor, and the balance of energy in and out is still "less in and out", in which case it will be "fat".

　　Gou Bo emphasized that obesity will directly affect heart function and vascular health, and it is easy to suffer from various cardiovascular and cerebrovascular diseases. The ideal situation is to "gain muscle and lose fat" on the premise of ensuring basic nutrition.

　　Old people can’t take extreme measures to lose weight, let alone go on a diet like young people. We can start with the moderation and choice of dinner, eat some coarse grains instead of staple food, eat food with high protein content for breakfast, and control the staple food at about 2 Liang at noon. It is not recommended to choose diet pills or surgery to lose weight.

　　In sports, it is suggested that aerobic exercise should be combined with strength training, and it is best to take some soothing forms, such as Tai Ji Chuan, yoga, walking, etc. As long as you can persist every day and achieve a certain amount of exercise, you can lose weight completely.

News from The Paper, Hebei, one of Gree Electric’s important markets, has suffered an unexpected change just as air-conditioning enterprises are preparing for the new freezing year.

It is reported that Hebei Xinxing Gree Electric Sales Co., Ltd. (Hebei Gree), a distributor in Gree Electric, issued a notice on August 18th, saying that on August 16th, Gree Electric suddenly stopped the delivery of goods to Hebei Gree, and asked the distributors who had invested money to plan and pick up the goods as soon as possible.

Just four days after Gree Electric cut off the supply of Gree in Hebei, on August 20th, Xu Zifa, the chairman of Hebei Xinxing Gree Electric Sales Co., Ltd., hosted a banquet for the mainstream distributors in Shijiazhuang five-star hotel, and announced at the meeting that he would quit the operation of Gree from today! At the same time, he promised to give everyone a reassurance, and the dealer’s payment, rebate and anwei fee will be cashed for everyone.

According to a reporter from The Paper who learned from an insider, the details of "Moutai that was drunk for 15 years that night, and 100,000 cash was distributed to 10 people at each table" were true. Xu Zifa also thanked the dealer for his support for so many years.

On August 23rd, a reporter from The Paper called Hebei Gree, and the staff who answered the phone said "there is no obligation to answer whether the company will continue to sell Gree air conditioners" and "if you want to buy Gree air conditioners, the market is everywhere".

Gree Electric also chose to play it cool. As of press time in The Paper, Gree Electric has not responded positively to this matter.

However, The Paper reporter learned from a number of people in the home appliance industry that Gree Electric really fell out with Hebei Gree. Next, Gree Electric will re-establish distribution channels in Hebei.

Some media reported that after Gree stopped supplying to the general distributor in Hebei, Gree Zhuhai Headquarters sent a 50-member marketing team to Hebei, bypassing the original general distribution of Gree in Hebei and contacting local agents. The Paper reporter also learned from insiders that the situation is basically true.

The strength of Hebei Gree should not be underestimated.

Hebei Xinxing Gree Electric Sales Co., Ltd. is one of the most powerful distributors in Gree Electric. Jinghai Internet Technology Development Co., Ltd. (Jinghai Internet), which was established by Hebei Gree and more than a dozen Gree Electric distributors, is an important shareholder of Gree Electric. As of the first quarter of this year, Jinghai Internet holds 8.34% of the shares of Gree Electric, ranking the third largest shareholder.

Tianyancha information shows that Hebei Gree indirectly holds 28% of the shareholders of Jinghai Internet and is also the largest shareholder of Jinghai Internet.

However, on June 24th this year, Gree Electric announced that it had received the Notice of Share Reduction from Jinghai Internet, a shareholder holding more than 5% of the shares. On June 24th, 2022, Jinghai Internet reduced its shareholding by 110,219,217 shares, accounting for 1.86% of the total share capital of Gree Electric, and cashed in 3.5 billion yuan. After the reduction, the shareholding ratio of Jinghai Internet decreased to 6.47%.

More importantly, as a major distributor in Gree Electric, Xu Zifa is also an investor in Philips Air Conditioning, which may also be one of the reasons for the deadlock between the two sides.

On August 9th this year, at the new product launch conference held by Philips Air Conditioning, Huang Hui, the former CEO of Gree Electric, appeared as the chairman of Philips Air Conditioning, Vinfom Hu, the assistant to the former president of Gree Electric, became the president of Philips Air Conditioning, and Xu Zifa attended the meeting as the shareholder representative of Philips Air Conditioning.

Gree turned into a competitor of Gree, which obviously angered Gree.

Liu Buchen, a senior home appliance observer, said in an interview with a reporter from The Paper that Gree Electric must be very dissatisfied with this practice of Hebei Gree. Before that, Gree Electric asked the dealer to choose one, and if he wanted to represent Gree, he could not represent Philips.

"Hebei Gree has both active and passive factors in doing so. Passive factors Gree Electric has promoted channel transformation in recent years, and the proportion of online sales has become higher and higher, which has affected the interests of traditional dealers and forced them to seek new ways out; However, investing in Philips is definitely the initiative of Hebei Gree. Considering so many years of experience and resources, I will try Philips air conditioning. " Liu Buchen said that he is not optimistic about the future prospects of Philips Air Conditioning and will not pose a threat to Gree.

However, Liu Buchen believes that it will take time for Gree to change the Hebei channel and find a suitable candidate, which may have a negative impact on Gree’s local sales.

However, the Hebei dealer incident did not bring much pressure to Gree Electric’s share price. On August 23rd, Gree Electric closed at 30.23 yuan, a decrease of 0.85%. The total market value of Gree Electric is 170.2 billion yuan.
