The original distressing Jiushu 39 Health Network

In the group match of Asian Youth Badminton Championship on June 30th, 17-year-old Zhang Zhijie of China Badminton Team suddenly fainted and died after being sent to hospital for rescue.

According to the press conference of Indonesian Badminton Association on July 1st, the treatment and examination results of Air Force Central Hospital and Central General Hospital showed that Zhang Zhijie died of sudden cardiac arrest.

In the face of sudden bad news, many teammates of Zhang Zhijie expressed their condolences over his death. Some teammates said that "Zhang Zhijie was in good health at ordinary times and had never heard of any diseases".

The death of such a young and promising child is really sad, and his departure also reminds us that even people who seem to be healthy at ordinary times may die suddenly.

This has a great relationship with the reasons behind sudden cardiac arrest.

Cardiac arrest refers to the sudden stop of the heart, which leads to the interruption of blood circulation, and the organs of the body can not get enough oxygen and nutrition. If not rescued in time, the patient will soon die.

This is often the main cause of sudden cardiac death.

According to China Cardiovascular Disease Report, about 544,000 people die of sudden cardiac death (SCD) every year in China, which is equivalent to one person dying of cardiac arrest every minute.

Because of the rapid onset and unpredictable onset time of sudden cardiac death, sometimes people around you will be gone before they can react, so it is very important to understand its inducement, symptoms before coming and preventive measures.

Although sudden cardiac death is urgent, it is not completely untraceable. Today, Uncle Jiu came to explore the "trace" of sudden death.

During strenuous exercise, the myocardial oxygen demand increases, which will aggravate the heart load. If the cardiovascular function is inherently impaired, it is easy to cause oxygen imbalance, myocardial necrosis, and eventually lead to sudden cardiac death.

In addition, long-term or strenuous exercise may also lead to a lot of sweating, which in turn leads to electrolyte imbalance, especially the loss of potassium and sodium ions, resulting in hypokalemia.

Once patients with myocardial infarction are complicated with hypokalemia, it is easy to cause malignant arrhythmia, such as ventricular tachycardia or ventricular fibrillation, which leads to a sharp drop in blood supply and even cardiac arrest. Sudden cardiac death is easy to occur if the rescue is not timely.

Clinical data show that hypokalemia is the most common cause of sudden death in badminton or marathon.

A study of 5,516 cases of sudden death in chinese journal of critical care medicine in 2020 found that sudden cardiac death was the primary cause of sudden death, accounting for 57.76%.

The second place is emotional excitement, accounting for 25.66%.

When angry, the blood flow of the heart doubles than usual, the contractility of the heart is strengthened, the heartbeat is accelerated, and a large amount of blood rushes to the heart, which is easy to induce angina pectoris and myocardial infarction, and then lead to sudden death.

Modern people have a fast pace of work, great pressure in life, and often stay up late to be a demon, which is easy to make their bodies overworked.

At this time, the body will continue to be tense, the nervous system is also highly tense, and the sympathetic nerve has been stimulated, thus raising blood pressure and increasing the burden on the heart.

Overwork can also lead to an increase in heart rate and increase the oxygen consumption of the heart, which may lead to acute myocardial infarction in severe cases and then sudden cardiac death.

Sudden cardiac death is closely related to heart problems, so people with cardiovascular diseases are more likely to be targeted.

If suffering from coronary heart disease, it will cause myocardial infarction, leading to myocardial necrosis and cardiac dysfunction;

Cardiomyopathy makes the structure and function of myocardium abnormal, which increases the risk of arrhythmia and sudden cardiac arrest.

Severe arrhythmia, such as ventricular fibrillation and ventricular tachycardia, can make the heart lose its effective pumping function, lead to insufficient blood supply and eventually lead to sudden death.

Conditions such as congenital heart disease and myocarditis can also lead to similar heart events.

Therefore, people with basic diseases should especially take care of their hearts.

For young people, the main causes of exercise-induced sudden death are coronary heart disease and hypertrophic cardiomyopathy. In addition, excessive tension, excitement, fatigue and other factors will also increase the risk of sudden cardiac death in young people.

Middle-aged people, especially those aged between 30 and 63, are often at high risk of sudden cardiac death. Because of the pressure of work and life, staying up late and working overtime, irregular diet and other factors, they are more prone to coronary heart disease.

Older people are more susceptible to myocarditis, heart failure and other diseases, which will lead to the gradual decline of heart function, thus increasing the risk of sudden cardiac death.

Although sudden death is urgent and heavy, it often sends us a distress signal before it happens, which must not be ignored.

If you have severe, tight and crushing pain in your chest, you need to be vigilant when you feel like your chest has been squeezed repeatedly and you feel suffocated.

Chest pain is also a typical manifestation of coronary heart disease, which generally occurs behind the sternum. More attention should be paid to this situation.

Our emotions will also protect our bodies. If there is a sense of panic at this time, don’t ignore the "alarm" of your body. No matter what you are doing, stop and observe immediately.

In addition to chest pain, in the absence of injury or illness, shoulders, chin, throat, teeth appear pain, and sometimes feel depressed, this situation should also be vigilant.

If a patient with hypertension suddenly has severe headache or even vomiting, it is necessary to highly doubt whether a cerebrovascular accident has occurred, and beware of sudden death.

In addition to pain, if there are obvious cyanosis, purple lips and decreased blood oxygen, it is highly doubtful whether there is pulmonary embolism.

Acute pulmonary embolism, if not handled properly in time, will easily lead to pulmonary infarction, blood circulation disorder and sudden death.

On the premise of no lack of sleep, strenuous exercise or illness, there is an unrelenting sense of fatigue for days, weeks or even months.

And accompanied by insomnia, anxiety, waking up at night and other symptoms, it is necessary to consider whether there is a heart problem.

Before sudden cardiac death, many patients will have a lot of cold sweat, which is one of the typical manifestations of myocardial infarction.

If you don’t have a history of heart disease, but suddenly you have sweating, palpitation, chest pain and other symptoms, you must not be careless, and you must see a doctor in time.

First of all, take responsibility for your health.

Maintain healthy living habits, feel your physical condition with your heart, and be alert to every alarm signal.

When you feel chest tightness, chest pain, dizziness and unknown pain, it is the body that reminds you that it is time to rest. Don’t sacrifice your life in pursuit of temporary efficiency.

Sedentary people should also pay attention to standing up and walking every hour or two, which can effectively promote blood flow in the legs and avoid pulmonary embolism.

Second, pay attention to your emotions.

If you know that you are angry, angry, grumpy and emotional, you should control it properly and find the right way to relieve your emotions.

Take things slowly, sometimes it will be faster.

If you find that you have signs of sudden death, don’t panic, rest quietly first, lie down when you are comfortable, and sit when you are comfortable, but don’t move unless necessary.

If there is oxygen inhalation equipment nearby, you should take oxygen as soon as possible with the help of your family or people around you.

At the same time, take the first-aid medicine that you carry with you immediately, such as chewing nitroglycerin and putting it under your tongue.

Patients with angina pectoris can usually relieve their pain in about two minutes. If the effect is not good, they can take a piece of nitroglycerin under their tongue 10 minutes later and call 120 emergency number quickly.

Finally, if you have spare capacity, you may be able to do your part by learning some first-aid skills when people around you suddenly fall to the ground and have signs of sudden death.

A report published in Military Medical Research shows that after cardiac arrest, the recovery rate of heartbeat can reach 41.7% if the rescue time is within 0~5 minutes; However, if the rescue time is within 5~10 minutes, the recovery rate of heartbeat is only 14.3%.

Therefore, in the first aid of sudden death, there has always been a saying of "golden four minutes". If we can grasp these few minutes, it is likely to save a life.

First aid can be done according to the following methods:

First of all, don’t carry or shake the patient, let him lie on his back on the ground, then pat the patient on the shoulder and call ta loudly.

Then observe the patient’s breathing: whether there is wheezing or abnormal breathing in the chest or abdomen (no more than ten seconds).

At the same time, touch the carotid artery for pulsation (non-medical personnel do not need to judge). At the same time, call for help loudly, and designate the personnel present to dial 120 emergency number. When there are no personnel present, call them quickly and keep effective communication with the medical staff in the emergency center.

If the patient is unconscious and his breathing and pulse disappear, chest compressions and artificial respiration should be performed immediately.

Pressing method: straighten your arms, one palm is close to the patient’s chest wall, the other palm is placed on the back of this hand, your fingers are crossed and held up, and the roots of your palms are forced.

Pressing position: the midpoint of the connecting line between the two nipples.

The compression amplitude and frequency are: the sternum sinks 5 ~ 6 cm (adult), and the chest fully rebounds after each compression, and the hands do not leave the chest wall, and the frequency is 100 ~ 120 times/minute.

按压时间与放松时间各占一半，放松时掌根部不要离开胸壁，以免按压点移位。

必要时进行人工呼吸：清理气道异物，仰头提颏法开放气道，一手捏鼻，嘴巴张大包紧患者嘴唇进行缓慢持续1秒钟吹气，吹气时余光观察患者胸廓是否微微起伏，放松捏鼻再次进行吹气。

按压和通气比例为30∶2，按压30次，人工呼吸2次，按压和人工呼吸5个循环后重新评估患者的意识、呼吸和脉搏。

*注意在开放气道的同时应用手指挖出病人口中异物或呕吐物，如有假牙者应取出假牙。

最后，如果旁边有自动体外除颤器（AED）就最好了。

设计AED的初衷就是让任何一个人都能毫无门槛地操作。因为情况紧迫，没有给人看说明书的时间，所以打开电源开关后，AED都是有语音提示的。

最后的最后，虽然九叔写文辛苦，但真心希望大家在生活中不会遇到上面的情况。

　　Although the birthplace of gunpowder, one of China’s four great inventions, is still a mystery, there is no doubt that Laojunshan area in Jiangyou is a veritable "hometown of gunpowder" as the largest industrial site of gunpowder discovered in China at present. A few days ago, the reporter learned from Laojun Mountain Scenic Area in Jiangyou City that the first gunpowder industry museum in China will be opened in October this year in Laojun Mountain in Zhonghua Town, and the history of the ancients collecting and smelting nitrate will be restored in the museum, and the gunpowder museum will also witness the eternal mystery of China’s gunpowder production. It is reported that the Laojunshan Ancient Glauber Site is actively making a lot of preliminary preparations for declaring the world cultural heritage.

　　find

　　More than 20 rich cultural relics in the ancient Xiaodong site

　　In December 2003, some cultural relics experts who planned tourism development for the local area first discovered many caves densely covered on the cliffs of Laojun Mountain, and since then, the ancient cave site of Laojun Mountain has attracted attention. Laojunshan Ancient Nitrate Cave Site is located in six towns and villages in jiangyou city, including Zhong Hua, Xinchun, Yongsheng and Wensheng, with a length of 21 kilometers. More than 20 ancient nitrate caves have been found, and Zhonghua Town is located between Sichuan and Gansu ancient roads, which is said to be the intersection of ancient important Yinping Road and Jinniu Road.

　　Professor Xu Xiangdong, a Beijing cultural relic expert (founder of National Cultural Heritage Administration Museum of Ancient Architecture), took the lead in exploring the ancient nitrate site in Laojun Mountain. According to him, Laojun Mountain is in a dangerous terrain. The local people call it "the nitrate cave" not only the Chaoyang cave, the largest nitrate cave in China, but also the Tianyu cave, the official cave, the rhinoceros cave, the goblin cave, the white cave, the dry cave, the horn cave, the Jiuxian cave and the Yanzi cave, which are several hundred meters deep. Xu Xiangdong and other experts felt "shocked" after entering the Nitrate Cave for inspection. They gave a high evaluation: "Its early time, large scale and high output rank first in the ancient gunpowder raw material sites discovered so far." On-the-spot investigation found that Laojunshan area is also an area rich in gunpowder-related cultural relics, and pottery fragments of Yuan, Ming and Qing dynasties were found in Chaoyang Cave, most of which were living utensils. Smoke and dust accumulated due to salting and lighting, the thickest part is 13.5 cm. Chaoyang cave is about 7.5 kilometers long, and there are stoves, nitrate pools and scraps everywhere. In the adjacent Yanzi Cave and Gaoguan Cave, such relics can also be seen everywhere. Therefore, it is more appropriate to build a gunpowder museum on Laojun Mountain.

　　conceive

　　Visitors can personally experience the process of making nitrate.

　　Rows of neat cooktops, nitrate pits and pools of different sizes … Visitors can even touch the labor tools and daily necessities used by the ancients themselves, and imagine the scene of the ancients cooking nitrate with wooden sticks at the hearth … The reporter saw the scene of the future gunpowder industry museum through three-dimensional animation in the office of Laojunshan Scenic Area. According to the preliminary plan, on the basis of Laojun Mountain Scenic Area, the museum complex will use special stone to imitate the working site of the ancient people making nitrate at that time along the path of climbing the nitrate cave, and the whole planned area will reach 3000 square meters. The gate of the Gunpowder Museum will be designed to look like a cave mouth, and the exhibition directors, widths and heights in the museum will also be simulated with reference to the real cave. The tunnels and working tables will try their best to be original, and relevant knowledge will be hung on the two walls of the tunnels. Stark Chan, general manager of Laojunshan Scenic Area, said: "This will enable tourists to experience industrial activities such as boiling and making nitrate in the nitrate field, and at the same time have a systematic understanding of the development of China’s gunpowder industry."

　　probe the secrets

　　How to smelt nitrate in the nitrate cave?

　　How is the nitrate in the cave formed? How did the ancients find nitrate caves in such dangerous mountains? And collect nitrate in the harsh natural environment of ancient times for the production of gunpowder? The reporter decided to go to the Xiaodong site with the staff of the scenic spot to find out.

　　Because the cave is almost opaque, the staff in the scenic spot have prepared torches in advance. The torches are made of local materials and diesel oil in bamboo tubes. Our destination is Tianyu Cave on Laojun Mountain in Zhong Hua. Along the rugged mountain road, under the leadership of Lao Zeng, a scenic spot worker, we quickly climbed Tianyu Cave. At the mouth of the cave, the reporter felt the temperature plummet. On the stone wall of the cave, Lao Zeng gently dug some white powder with his forefinger. He said, "This is nitrate. From the geological point of view, it is inferred that caves such as rain and rain are naturally formed, and nitrate is’ hidden’ in the soil layer, which was discovered by the ancients and mined. The mined nitrate soil must be soaked in water first, so there are nitrate pools. After the nitrate soil soaked to a certain degree is taken out of the nitrate pool, it is boiled in the boiler on the stove, and the boiled nitrate is crystal. "

　　Under the guidance of Lao Zeng, through the dim light of the torch, the reporter saw several stoves and nitrate pools in several corners of the cave, and obvious traces of smoking could be seen. The diameter of the stove is between 60 cm and 150 cm. Locals say that the hole is about 100 meters long and five or six meters wide. According to this estimate, Tianyu Cave can accommodate dozens or even hundreds of people working at the same time. Go to the end of the cave, you can hear the sound of rushing water. At the top of the cave tens of meters high, clear springs pour down, and there are ditches in the cave. It seems that people already knew how to draw water. All indications show that this place is a production base of advanced technology.

　　Coming out of the cave, Lao Zeng told the reporter: "This cave is not large in scale compared with the other 20 nitrate caves on Laojun Mountain, but the nitrate residue and scraps left by the ancients in the nitrate cave are piled up like mountains, and the traces of artificial mining are clearly visible. Regrettably, the age of Tianyu Cave and other nitrate caves on Laojun Mountain cannot be accurately demonstrated, but according to the rough judgment of the physical objects in the caves, it is certain that these nitrate caves and crafts were left over from the Qing Dynasty at the latest. "

　　prospect

　　The ancient mirabilite site is actively preparing for the application for World Heritage.

　　In May 2006, Laojunshan Ancient Glauber Site was approved by the State Council as the sixth batch of national key cultural relics protection units, and now Laojunshan Ancient Glauber Site has launched a sprint to the world cultural heritage. In order to declare the site of ancient glauber’s salt in Laojun Mountain as a world cultural heritage, in September 2006, Jiangyou Municipal Party Committee and Municipal Government also invited international experts on ancient sites and cultural relics to inspect Laojun Mountain. Experts agree that Laojunshan Ancient Glauber Site is an ancient industrial civilization, which has a certain foundation for applying for the World Heritage because it is related to China’s "Four Great Inventions".

　　Sharla Cheung, director of the jiangyou city Cultural Management Institute, said that there are some problems to be verified in the Laojunshan Ancient Nitrate Site itself, such as the historical dating of the ancient Nitrate Cave and the excavation management of the Nitrate Cave. At present, jiangyou city is doing a lot of argumentation work on these problems, and will conduct in-depth archaeological excavation when conditions are ripe, and strive to make all preparations for the application for the World Heritage.

IT Home reported on April 24 that during the Lantu Automotive Spring Technical Communication Conference held today, Huawei Smart Car Solutions BU CEO Jin Yuzhi announced the details of the cooperation between the two parties.

Jin Yuzhi said that the model of cooperation between Lantu and Huawei will be equipped with Huawei’s latest ADS 3.0 system and Hongmeng intelligent cockpit. The first model equipped with this solution will be Lantu Dreamer (IT Home Note: MPV models already listed, see the picture below), which will be released in the first half of next year.

Lantu also announced that it will launch a new pure electric SUV model this year. It is reported that the two sides signed a strategic cooperation agreement in January this year, and Lantu’s subsequent models will use more Huawei intelligent related technologies.

Earlier today, Huawei released its new brand "DANGZHOU". Huawei’s DANGZHOU smart car solutions cover chips, hardware, software, and cloud, and released ten new products, including DANGZHOU smart driving, DANGZHOU car cloud, DANGZHOU car control, and Hongmeng cockpit.

Among them, Dry Smart Driving ADS 3.0 adopts a new architecture of 3.0 and is equipped with an omnidirectional anti-collision system CAS 3.0; it supports parking spaces to parking spaces, and parking and driving all scenarios for commercial use.

Huawei said this morning that Huawei has launched the first year of smart driving commercial scale, and new cars such as Dongfeng, Changan, GAC, BAIC, Sailis, Chery, and Jianghuai will be equipped with smart car solutions. Huawei also stressed again that it does not build cars, with the goal of helping car companies build good cars.

In March this year, the State-owned Assets Supervision and Administration Commission of the State Council said that the development of state-owned automobile enterprises in new energy vehicles was not fast enough, and conducted a separate assessment of the new energy automobile business of three central automobile enterprises. These enterprises are the central automobile enterprises directly supervised by the State-owned Assets Supervision and Administration Commission, including FAW Group, Dongfeng Group, and Changan Group. Lu Fang, CEO of Lantu, said that the "separate assessment" policy is a very big encouragement for the company, and the strategic determination and development confidence are more firm. It is also conducive to the company to let go of its hands and feet, work quickly, stimulate innovation vitality, meet user requests, and increase market share.

　　From the breakthrough of "Galaxy" in achieving "zero" of our country’s supercomputer, to the "Tianhe" supercomputer ranking first in the world for many times, over the past 40 years, the scientific researchers of the National University of Defense Technology have fully carried forward the "Galaxy Spirit" and written one glory after another on the road of China’s scientific and technological development –

　　"Galaxy" and "Tianhe": Let the five-star red flag be planted on the top of the world’s supercomputing

Tianhe-2 supercomputer room. (file photo) He Shuyuan, photo

　　In the midsummer of August, at the National Supercomputing Center in Changsha on the banks of the Xiangjiang River, the "Tianhe" series of supercomputers developed by the National University of Defense Technology were in full swing. The peak computing power of 2 quadrillion times per second is equivalent to 50,000 personal computers computing at the same time, providing strong support for the development of scientific research, information services, equipment manufacturing and other fields, and producing important application benefits.

　　Supercomputers are an important symbol of a country’s scientific and technological level and strategic capabilities. From the "Milky Way" to achieve the "zero" breakthrough of our country’s supercomputers, to the "Tianhe" supercomputer that has repeatedly won the top of the world’s supercomputers, over the past 41 years, the scientific researchers of the National Defense University of Science and Technology have held the motherland in mind, are not afraid of difficulties, innovate independently, and scale peaks bravely. They have written one glory after another on the road of China’s scientific and technological development.

　　"Galaxy" was born: China’s giant computer development achieved a breakthrough of "zero"

　　Today’s brilliance stems from yesterday’s humiliation.

　　In the 1970s, high-performance computing became a strategic high technology to promote technological innovation and economic and social development. However, without its own supercomputer, China’s economic and social development is often controlled by others. Explored mineral deposits and oil data have to be sent abroad for processing, which is not only expensive, but also the data must first be mastered by foreign experts.

　　"If China wants to carry out the four modernizations, it cannot do without a supercomputer!" In 1978, at an important meeting held by the Central Committee, Comrade Deng Xiaoping spoke eloquently. It was at this meeting that our country decided to develop a supercomputer independently to solve the problem of large-scale scientific calculation in the modernization drive. Comrade Deng Xiaoping solemnly entrusted this important task to the National Defense Science and Technology University.

　　At that time, although the National Defense University of Science and Technology was the first unit to develop computers in China, the previously developed "151" computer had a computing speed of only 1 million times per second. Now, to develop a machine with 100 million operations per second means that the computing speed should be increased by 100 times, and the technical difficulty can be imagined.

　　"Win glory for the Chinese nation!" Faced with unprecedented difficulties, the researchers held back their energy: they would risk their lives to come up with a giant machine to prevent foreigners from getting stuck in our necks.

　　"It was really a period of patience but passion." Li Sikun, a 78-year-old professor at the School of Computer Science at the National Defense University of Science and Technology, recalled the scene with emotion. After the development work began, various complex technical problems emerged. What kind of technical route to take? What kind of architecture to adopt? How to achieve a computing speed of 100 million operations per second… The problems are like "roadblocks". Scientists rose to the challenge, using the laboratory as a battlefield, and waging this battle without gunpowder smoke day and night.

　　At the beginning of reform and opening up, our country’s industrial base is weak, the processing equipment is simple, and the components are backward.

　　Li Sikun recalled that, for example, the circuit design of computer hardware was purely depicted on paper one by one, and if it was wrong, it had to be done again. For a small-scale integrated circuit design, it took half a month to draw.

　　In order to catch up, everyone ate in the factory, slept in the computer room, and worked until at least 12 o’clock at night. At that time, overtime pay was 20 cents a night, but no one was willing to take it. Everyone’s heart was to save every penny and build a Chinese giant machine as soon as possible.

　　Heaven rewards hard work! After five years of hard work day and night, the researchers represented by Professor Ciyungui have overcome one by one theoretical, technical and technological difficulties, and creatively proposed the "bidirectional array" structure, which greatly improved the computing speed of the machine. The development task was completed one year ahead of schedule, and the funding was only one-fifth of the original plan.

　　On November 26, 1983, our country’s first supercomputer with 100 million operations per second successfully passed the national technical appraisal, marking that China had achieved a "zero" breakthrough in the field of supercomputer development and became a country that could independently design and manufacture supercomputers after the United States and Japan.

　　General Zhang Aiping, then the director of the National Defense Science and Technology Commission, wrote a poem about the supercomputer, naming it "Milky Way" and writing a poem: "Hundreds of millions of stars are in the Milky Way, and it is difficult for the world to know how many there are. The ingenious arrangement is clever, laughing at the stars and singing."

　　Since then, they have relied on independent innovation to successively develop a series of giant computers such as "Galaxy-II" and "Galaxy-III", which have gradually pushed our country’s high-performance computing technology to the international forefront, and gradually solved a series of urgent problems in economic and social development.

　　In June 1997, when the "Galaxy-III" with a computing speed of 13 billion times per second was successfully developed, the National Weather Service used it as a medium and long-term numerical prediction system, and the weather forecast was advanced from two or three days in advance to about seven days in advance.

　　"Tianhe" comes out: China’s supercomputer development level ranks among the top in the world

　　After entering the new century, our country’s various undertakings have entered a period of rapid development, and there is a more urgent demand for the computing speed and capacity of high-performance computing machines. However, compared with developed countries, our country is not only an order of magnitude different in computing power, but also far from the number of installed machines.

　　The National Defense Science and Technology University was once again tasked with shouldering the heavy responsibility and sounded the charge to climb the world’s scientific and technological peak – to develop our country’s petaflop supercomputer system as soon as possible.

　　The development of the world’s supercomputers shows that every order of magnitude increase in computing power requires architectural innovation and a series of new breakthroughs in key technologies. At that time, although the National Defense University of Science and Technology had relatively strong technical accumulation and rich experience in engineering practice, it was equally difficult to achieve a technological leap from 100 trillion to quadrillion.

　　Faced with various technical problems and severe challenges, researchers work together, innovate independently, and strive to overcome core and key technologies to promote the development of high-performance computing in our country.

　　The reason why the "Tianhe" supercomputer has the fastest computing performance in the world lies in its original CPU + GPU heterogeneous architecture. However, this new heterogeneous system encountered a series of major technical bottlenecks during the creation process.

　　Professor Yang Canqun, deputy chief designer of the "Tianhe" supercomputer, recalled that the GPU is characterized by graphics and video processing. To combine it with a CPU that is good at computing, it is not only difficult to program, but also very inefficient. The internationally recognized computing efficiency is only 20%.

　　The key to innovation lies in how to turn "impossible" into "possible" and find a way where there is no way.

　　"When I get up in the morning, I start working, and when I go to bed at night, I close my eyes, and the data on the screen is still scrolling in my mind." Yang Canqun and the members of the research team began a four-month research project. After 80,000 many experiments and performance optimization, they finally found a breakthrough, making the computing efficiency of the GPU reach 70%, creating a world miracle.

　　In order for a supercomputer system to achieve quadrillions of operations per second, it must also have a fast and smooth network system that allows all kinds of information to "run fast". They designed a new switch scheme for this purpose, but the American chipmakers refused to support it and demanded that it be designed according to the American scheme. But in this way, although success is certain, there is no innovation and advantage.

　　The research team of National Defense University of Science and Technology did not believe in evil. They insisted on following their own design route, exploring from scratch, and working hard to tackle key problems. In just 10 months, a new type of switch was developed, and the measured technical indicators greatly exceeded those of similar systems, while the cost was only 80% of that of similar products of the same scale.

　　With a series of key technological breakthroughs and engineering realization, on October 29, 2009, our country’s first petaflop supercomputer "Tianhe-1" was successfully developed, achieving our country’s independent research and development of supercomputer capabilities from 100 trillion times to 100 trillion times, becoming the second country in the world after the United States to be able to develop a petaflop supercomputer system.

　　Faced with the intense competition in the field of supercomputing, the researchers of National Defense University of Science and Technology did not revel in the joy of success, but quickly organized technological upgrades and comprehensive optimization, and embarked on the expansion of the second-phase system.

　　On November 17, 2010, the "Tianhe-1A" supercomputer topped the list of the 36th World’s Top 500 Supercomputers with excellent performance 4.70 quadrillion times at peak speed and 2.566 quadrillion floating-point operations per second.

　　The Chinese have planted the five-star red flag on the top of the supercomputing world for the first time, marking that China’s self-developed supercomputer comprehensive technology level has entered the world’s leading ranks.

　　On June 17, 2013, the "Tianhe-2" developed by them once again topped the global supercomputing 500 with a peak computing speed of 549 million billion times per second and a measured computing speed of 339 million billion times per second. Since then, "Tianhe-2" has ranked first in the world supercomputing list for six consecutive times.

　　In late July last year, the National Defense University of Science and Technology sent another piece of good news. The "E-class prototype system" led by the school completed the development and deployment and passed the acceptance, marking that our country launched a charge to the new generation of 10 billion billion billion times (E-class) supercomputers.

　　"Galactic Spirit": Forging the "Root" and "Soul" of China’s Scientific and Technological Glory

　　"Embrace the motherland, unite and cooperate, aim for the peak, and strive bravely." The 16 characters in the eye-catching position of the History Museum of the School of Computer Science and Technology of National Defense University of Science and Technology condense the arduous exploration of generations of "Milky Way People" at National Defense University of Science and Technology, and reveal the true meaning of success from "Milky Way" to "Tianhe". In their hearts, "Milky Way Spirit" is the spiritual highland they adhere to, and it is also their "root" and "soul".

　　For decades, the research team of National Defense University of Science and Technology has sacrificed the leisure of holidays, the warmth of family, postponed the wedding date, delayed medical treatment, and gave up going abroad for further study. Many people have dedicated their youth and even their lives to the supercomputer development of the motherland without any regrets.

　　Tianhe-1 has a deputy chief designer who suffers from diabetes and other diseases. During the installation and commissioning of the second phase of the "Tianhe-1" system, he stayed in the computer room for half a year. His illness continued to worsen due to irregular life and diet, but he insisted on not leaving his post. It was not until news came from the United States that Tianhe-1 had topped the world supercomputer rankings for the first time that he walked out of the computer room and was admitted to the hospital.

　　Yu Wulong, a young lecturer, didn’t sleep for five days and five nights in order to design a high-level computer control system. On the sixth night, his wife, who woke up from her dream, found him still working at his desk like a demon. She grabbed the drawings on the desk and said, "If you keep fighting like this, I will cut these drawings into pieces!" The next morning, Yu Wulong went to Huangshan on a business trip again. No one expected that he fell ill at the foot of Huangshan and never came back.

　　There are also 43-year-old Jian Xianfu, 40-year-old Zhang Shusheng, 41-year-old Wang Yumin… At the National Defense University of Science and Technology, there are more than 20 scientific researchers who have sacrificed their young lives for the cause of the "Galaxy" series of supercomputers. They measure their lives with their careers and turn them into cornerstones to support the dream of China’s technological take-off.

　　Difficulties and hardships, Yu Ru Yu Cheng!

　　The laying of communication optical fiber is the first phase of the second phase of the "Tianhe No. 1" system to be stationed in the National Supercomputing Center in Tianjin, and the time is urgent and the task is arduous. In midsummer, due to the temperature of the trench reaching more than 40 degrees Celsius, the surface of the cement is too rough, and the insulating rubber of the newly laid optical fiber has been worn out with cracks, and the wire cores are exposed in some places. If this problem is not solved, the signal will be interrupted, the communication will be short-circuited, and the system will be disrupted.

　　Faced with this situation, the commander took off his clothes, jumped into the hot trench, and lay prone on the rough concrete floor. Everyone followed suit, and soon a "human flesh carpet" was laid, and optical fibers extended smoothly along the bodies of the officers and soldiers.

　　Dozens of people lay naked in the trench for dozens of days, scraped all over by the hard cement and optical fibers, leaving 15,000 optical fibers unscathed. On the day of the system test, the moment the machine was turned on, all the communication lines were unimpeded…

　　"It is this’Milky Way ‘spirit formed in overcoming obstacles and overcoming difficulties that has written the brilliant road of independent innovation with Chinese characteristics," Hu Qingfeng, a professor at the Computer Research Institute of National Defense University of Science and Technology in his 60s, told reporters with relief.

　　At present, the Tianhe supercomputer system is used in the National Supercomputing Center in Tianjin, the National Supercomputing Center in Guangzhou, and the National Supercomputing Center in Changsha.

　　Among them, the Changsha Center is the only national-level supercomputing center in the central and western regions of our country, with the "Tianhe-1" supercomputer and the "Tianhe Tianma" artificial intelligence computing cluster. "Tianhe-3" will also be settled in the center in 2020. Relying on the Tianhe supercomputer system, the center has formed an integrated innovation application service platform for industry-university-research that integrates "scientific and technological research and development, technological innovation, public services, and talent training": supporting national and Hunan scientific and technological innovation, providing a total of 1205 users with high-performance computing, big data, cloud computing, and artificial intelligence services, supporting 142 national scientific research projects, and more than 430 other provincial and ministerial scientific research projects and enterprise cooperation projects; innovating service models, establishing a number of supercomputing sub-centers, industry joint laboratories, industrial park supercomputing service stations, etc.; building enterprise big data, financial risk control, SME supercomputing community, simulation services, video merchandise and other innovative platforms to serve the development of the whole industry; keep an eye on international The national science and technology frontier will build a popular science base and a "supercomputing star" crowd-creation space to help scientific and technological innovation and talent training in Hunan and the central and western regions.

　　Witnesses say

　　Advanced layout, independent innovation

　　Dictator: Dong Dezun, Deputy Chief Designer of "Galaxy"/"Tianhe" New Generation High-performance Computing Interconnect System

　　I have been working in the Research Room 604 of the Institute of Computer Science, School of Computer Science, National University of Defense Technology since I graduated with a doctorate in 2010.

　　Laboratory 604 is a research collective with a long and glorious history and a glorious tradition. It has always been a key technical team in the development of the high-performance computing system of "Galaxy" and "Tianhe". I was fortunate to accompany the collective through the whole process of the development cycle of "Tianhe-2".

　　The "Milky Way" and "Tianhe" team has always kept up with the international forefront in the development of high-performance computing systems, planning ahead, and using technological progress to promote the development of applications. In fact, when "Tianhe-1" was ranked first in the world supercomputing at the end of 2010, the "Tianhe" general division team had already started planning the work of "Tianhe-2".

　　In the early days of the "Tianhe-2" project, I participated in the project demonstration work. At the same time, as a researcher of the high-speed interconnection system, I experienced countless project discussions, centralized closed development, and system-wide debugging of the interconnection subsystem. Especially in the first half of 2013, in order to catch up with the progress, we worked 24-hour shifts for system-wide debugging, and everyone often slept on the floor in the computer room and debugging room at night. At that time, it was May and June, and Changsha had already begun to heat up. Due to the focus of the power supply system of the National Defense University of Science and Technology, the air conditioning of the whole school’s offices was stopped, but the debugging room we were in was extremely cool, which could be regarded as a "benefit" brought by the adjustment.

　　In the process of participating in the demonstration and development of the "Tianhe" interconnection system, I realized that the "Tianhe" team attaches great importance to basic research and the spirit of independent innovation. The development of high-performance computing systems places special emphasis on the hardware and software collaborative design methodology, and the effectiveness of the collaborative design methodology depends on the continuous performance evaluation ability of changes in hardware-software applications. In the later stage of the "Tianhe-1" project, our interconnection team began to lay out and develop independent collaborative design tools for the "Tianhe" system.

　　So far, after more than 8 years of continuous independent development, we have broken through key technologies such as application-driven large-scale high-performance interconnection network performance evaluation, developed large-scale high-performance interconnection network simulation software that supports real application load, accurate network function model, and good scalability, filling the long-term gap in this field of the "Tianhe" team and even our country, and providing a powerful independent design tool for the "Tianhe" high-performance interconnection communication network to continue to maintain international leadership.

1905 movie network news Today, the Chinese crime action giant released a trailer for "Left-handed genius and right-handed madman", and exposed a set of "light in the dark" version of the character poster. The trailer focuses on the two sides of Fang Mu’s "genius" and "madman" played by Deng Chao. With Fang Mu’s vigorous and powerful monologue, the audience is led into the complex inner world of the criminal investigation master. The poster of the characters exposed this time outlines the outline of the characters with dark golden lines, blood stains form a symbol of each character, guns symbolize Deng Chao’s identity as a police officer, axes are the criminal weapon of Ruan Jingtian’s Jiang Ya, and sharp blades highlight the super-strong action of Mi Nan played by Liu Shishi, Wei Wei played by Lin Jiaxin symbolizes love with roses, and Guo Jingfei plays Ren Chuan in an invisible cage.

The movie will be released this Saturday and will be released nationwide on December 22.

　

The acting is hard! Deng Chao played Fang Mu, and the original author sent a long article saying that he saw tears

"City Light of Psychological Crime" features Fang Mu (Deng Chao), a criminal psychologist who specializes in criminal psychology, and tells the story of his high-intelligence serial murder with the help of his assistant Mi Nan (Liu Shishi). As a crime blockbuster, the film gathers domestic A-list actors such as Deng Chao, Ethan Ruan, and Liu Shishi. The film is adapted from "City Light", the final work of Remy’s series of novels of the same name. Last week, Deng Chao, director Xu Jizhou and the original author Remi Bing split into two ways to send this crime film, which took five years to build, to audiences across the country. The film’s first "quality inspection" was very good, and it was praised as "the hardest crime movie of the year". In the film, Deng Chao’s acting skills were once again recognized by the audience: "Deng Chao is too suitable for Fang Mu, and it can be said that it is a big explosion of acting skills." At the same time, the story of the film was also unanimously recognized by the audience: "This movie is different from other crime movies, it is very bold, and the story is based on real events around you, and it is not floating."

As an IP movie adaptation, adaptations and respect for the original book have always been impossible to have both. "City Light of Psychological Sin" maintains a good balance in this regard. Some fans of the original book commented after watching the movie: "From the plot to the characters, as well as the deep core that the novel wants to express, it has reached a 1:1 reduction. It is the best adapted movie I have seen this year, very surprising." After the film’s first public screening, Remy, the original author of the novel, excitedly wrote the first long film review of the film, recalling that in the preparatory stage of the film, he still remembered "to show the case while preserving the space for shaping the characters, and to talk to Director Xu Jizhou about the short circuit of the brain." When the film was finished, Remy sighed to the stars in the film, "They are Fang Mu, Minan, Jiangya, Wei Wei and Ren Chuan who came out of the novel." As the most satisfactory adaptation of Remy’s works, he was moved to tears after the first viewing.

　

The hardest behind-the-scenes gold medal team! Producer Jiang Zhiqiang: It’s difficult to make new themes, but I like challenges

　　　　

In the past few days of the roadshow, "City Light of Psychological Sins" has accumulated high popularity and reputation. At a roadshow event in Chengdu, the film’s director Xu Jizhou shared the story of the behind-the-scenes shooting for the audience. It is reported that from the first time he saw the novel to the final film, it took nearly 6 years. In order to preserve the soul of the original work, the entire behind-the-scenes team demanded strict details and scenes. The director was even ridiculed by Remi: "He is a lunatic." It is also relying on this persistent spirit that today’s film has been completed with such a high degree. Mr. Jiang Zhiqiang, the producer of the film, revealed: "I have been making films for decades, and this is the first time I have made a purely mainland crime film. Six years ago, when I saw the script of "City of Light of Psychological Sins", I was very excited and wondered if this movie could be made? I don’t want to make a more fake crime theme, there is no intensity. This movie is shocking, I know it will be difficult, but I like challenges the most. In the past, crime movies rarely had anything to do with the lives of the audience, and what "City of Light" wrote happened all around us and really touched the hearts of the audience. Chinese movies need to explore new themes and need us to guide the audience. The process is of course very difficult, just work hard, don’t give up, and move forward. "

In order to create this unprecedented film, the film assembled a luxurious behind-the-scenes team, with Zheng Zhaoqiang of, as the director of photography, Qiu Weiming of, and Qiu Weiming of, as the director of art, the director of action and martial arts, respectively, as the director of Kenji Tanigaki and Wu Gang, and Jin Peida of, as the music director, and Wang Baoyi of "Poison War" as the styling director. According to statistics, the members of the behind-the-scenes team have won and nominated more than 60 times in major film awards such as the Golden Horse Awards and the Academy Awards.

　

The film is directed and written by Xu Jizhou, produced by Ren Zhonglun and Jiang Zhiqiang, and adapted from Remy’s novel of the same name. It stars Deng Chao, Ruan Jingtian, Liu Shishi, and Wen Qi. Lin Jiaxin starred in it, and Guo Jingfei and Remy starred in a friendship. The film will land in theaters nationwide on December 22.

Wang Jianlin could finally breathe a sigh of relief.

"Daily Economic News" reporter learned from the official website of Wanda Group that on December 12, Pacific Alliance Investment Group(PAG)And Dalian Wanda Business Management Group(Hereinafter referred to as Wanda Business Management)Joint announcement of the signing of a new investment agreement. PAG Investment Group will work with other investors to redeem its investment in Zhuhai Wanda Commercial Management Group upon the expiration of its investment redemption period in 2021(Hereinafter referred to as Zhuhai Wanda Business Management)And reinvest.

It is reported that the investment amount of existing investors in Zhuhai Wanda Commercial Management in August 2021 is about 38 billion yuan, of which the investment amount of PAG Investment Group is about 2.80 billion US dollars(About 18 billion RMB), Existing investors enjoy redemption rights in the original investment arrangement. According to the new agreement, Wanda Commercial Management holds 40% of the shares, which is the single largest shareholder. Several existing and new investor shareholders such as Pacific Alliance Investment Group participate in the investment, with a total shareholding of 60%. On the issue of listing, the new investment will no longer set up a gambling agreement.

This also means that there are 18 days left until the final IPO time.The gambling pressure of Wanda Commercial Management has been basically eliminated.

It is worth noting that,This investment is also a workout.Therefore, Wanda has also paid a certain proportion of the equity price.

First, exchange of equity for investor consent

For Wanda Commercial Management, by the end of 2023, the greatest pressure will be the arrival of the listing and betting period.

In August 2021, Wanda Commercial Management and Zheng Yutong family, Country Garden, CITIC Capital, Ant, Tencent, Pacific Alliance Investment Group and other 22 institutional investors signed a gambling agreement. The above investors invested about 38 billion yuan in Zhuhai Wanda Commercial Management, of which Pacific Alliance’s investment is about 2.80 billion US dollars(About 18 billion RMB)…

According to the gambling agreement, if Zhuhai Wanda Commercial Management fails to complete the listing work by the end of 2023, Wanda Commercial Management is obliged to repurchase shares from the above investors, and the repurchase amount exceeds 30 billion yuan.

According to the latest agreement signed between Pacific Alliance Investment Group and Wanda Commercial Management, upon the expiration of the investment redemption period in 2021, Wanda Commercial Management will be required to redeem the investment before Pacific Alliance Investment Group will cooperate with other investors to reinvest in Zhuhai Wanda Commercial Management.

On the same day, according to the surging news, Zhuhai Wanda Commercial Management revealed in the process of communication with investors that Wanda Group plans to sell its Wanda Plaza in first- and second-tier cities in exchange for liquidity, and is negotiating with insurance institutions.

This year, the sale of Wanda Plaza is not the first time. The most recent one was on October 8 this year, when Guangxi Hepu Wanda Plaza was sold to Guangxi Beihai local real estate enterprise Hepu Wanghe Real Estate Co., Ltd. According to public information, in April 2021, Wanda Plaza was stationed in Hepu, Beihai, and the project officially opened in January 2022. Hepu Wanda Plaza has also become Wanda’s first county Wanda Plaza in Guangxi.

The transfer of the project comes just a week after Wanda Commercial Management transferred a 100% stake in its Shanghai project, Shanghai Wanda Plaza Real Estate Co., Ltd. According to Qichacha, on September 28, Shanghai Wanda Plaza Real Estate Co., Ltd. underwent industrial and commercial changes. The original wholly-owned shareholder Wanda Commercial Management withdrew and added Shanghai Jiayuan Management Consulting Partnership(Limited Partnership)Wuhu Puyu Equity Investment Partnership(Limited Partnership)At the same time, the legal representative was changed from Zhang Jing to Fengshun, and the main personnel were also changed.

The Shanghai Jiayuan Management Consulting Partnership is held 90.91% by our investment holding limited liability company, and our life insurance joint stock company is indirectly held.

The Shanghai Zhoupu Wanda Plaza is also the fourth Wanda Plaza that PICC has taken over this year. In May this year, PICC took over three projects from Wanda Commercial Management: Shanghai Songjiang Wanda Plaza, Jiangmen Taishan Wanda Plaza and Qinghai Xining Wanda Plaza. In addition, China Huarong took over the Wanda Plaza project on Xinhan Street in Wuhan.

Every time the reporter combed the Zhuhai Wanda Business Management prospectus, he learned that,The above-mentioned project subject companies are not included in their listed assets under management.For example, Shanghai Wanda Plaza Real Estate Co., Ltd. does not appear in the prospectus, but a company named Shanghai Wanda Plaza Commercial Management Co., Ltd. appears.

Zhao Liying, for her work "Do You Know If You Should Be Green, Fat, Red and Thin," was nominated for both "Audience Favorite Actress" and "Best Actress" at the 30th China Television Golden Eagle Awards.

As soon as the list of winners was announced, the matter rushed into the hot search. After all, for Zhao Liying, who had won the Golden Eagle Award once before, the double nomination this time used her acting skills and works to prove that Zhao Liying’s strength and traffic coexist. For Zhao Liying, who just had a baby and came back, it is indeed a good thing to congratulate.

However, Zhao Liying is unlikely to become king in a battle. On the one hand, Zhao Liying once won the audience’s "Favorite Actress" award, and on the other hand, her competitors in the "Best Actress" are particularly strong.

Since China entered the 21st century, the actress with the best total audience rating of all works, this time relying on Jiang Wenli, nominated for "Little Woman Under Zhengyangmen", has not appeared in modern dramas for many years, this time playing the real estate agent in "Anjia" Sun Li, has won many awards with "Little Joy", called by Qin Hailu as "as long as you act" Xiao Tao Hong, finally got rid of the label of Xiao Zhang Ziyi, earned tears in the audience in "Big River" Tong Yao and in the eyes of many netizens, the name is a bit unfamiliar, the heroine of "Persimmon Red Every Year" Wang Qianhua.

And it is precisely this Wang Qianhua, whom many netizens do not know, that is the real queen of rural drama ratings. This actress’s play has never failed, even in broad daylight reruns, her TV drama audience rating can still break one.

Many viewers first knew that she was from the "Woman in Charge", which easily told a story in just 18 episodes. Her role as Zhang Juxiang showed the indomitable spirit of Chinese rural women, and she became famous all over the country with this work. The play also won the first prize of the first rural TV drama theme award. Wang Qianhua herself won the Flying Heaven Award for Outstanding Actress that year, and embarked on the road to the countryside.

This is also the second time she has been nominated for the Golden Eagle Award. She has already won the best actress once when she starred in the TV series "Women’s Village" with the theme of left-behind women and children in the new countryside. There are also a series of works such as "Wheat Goes to Town", "Nine Nine Nine", "Guanzhong Woman", "Party Daughter" and "Black Gold Land Woman", which have placed her firmly in the "Queen of Country Drama" position.
