The University of Hong Kong announced today (16) on its website that it would cancel its graduation ceremony, which was scheduled to be held from the end of November to December.
The university decided to cancel its graduation ceremony, which was scheduled to take place from the end of November to December, in view of the continuing uncertainty and the disruption of transportation services, the statement said. The university will inform the graduates about obtaining the diploma and other relevant arrangements. The college will also decide whether to hold a celebration for graduates at a different time in this academic year.
For some time, violence has been raging on Hong Kong’s university campuses. In addition to HKU, other universities announced the cancellation of the graduation ceremony. According to Hong Kong media, City University of Hong Kong announced on November 14 that it would cancel the graduation ceremony of the college originally scheduled to be held from November 16 to December 8 and the graduation ceremony of the whole university on November 23.
The Chinese University of Hong Kong also announced the cancellation of the 88th graduation ceremony and honorary degree awarding ceremony, which was scheduled to be held next Thursday (21). The awarding of doctor’s degree will still be held on the same day (21) in the absence of graduates, and the graduation certificate will be distributed later. According to the University, the commencement ceremony and honorary degree awarding ceremony have been cancelled due to the disruption of public transport services, which has seriously affected the access to campus traffic and the safety of graduates, their families and friends. The university will set another time to hold a celebration for the graduates. The honorary degree awarding ceremony will be held in due time.

Mohandas Karamchangde Gandhi
Respected as “Mahatma Gandhi” (Mahatma Gandhi), leader of the Indian National Liberation Movement and leader of the Indian National Congress.

Mohandas Karamchangde Gandhi was born into a Hindu family, and his father was the prime minister of the local Tuban. Gandhi went to the UK to study law when he was 19 years old. In 1893, Gandhi came to South Africa under British rule, leading South African Indians to fight for rights. He combined the Hindu benevolence, vegetarianism, and non-killing ideas with the benevolence thoughts in the Bible and the Qur’an, and absorbed the essence of the thoughts of Solon and Tolstoy, and gradually formed non-violence. Cooperation theory.

In 1915, Gandhi returned to India and soon became the actual leader of the Congress Party, making “non-violence and non-cooperation” the guiding ideology of the Congress Party and starting to run for India’s independence. After World War II, India split into two countries, India and Pakistan. In the face of the conflict between the two countries, Gandhi, which has an important influence on both sides, has repeatedly used hunger strikes to influence them and call for unity. On January 30, 1948, Gandhi was assassinated by Hindu patriarchs.

Gandhi is the founding father of India and the modern political doctrine that advocates non-violent resistance – the founder of Gandhism. His spiritual thoughts led the country to independence and to break away from British colonial rule. His “non-violent” philosophical ideas have influenced nationalists around the world and an international movement for peaceful change.

70 Years of Chinese Intelligent Manufacturing

Since the founding of the People’s Republic of China 70 years ago, China’s industrial production capacity has increased rapidly. The output of major industrial products has entered the forefront of the world and become the world’s largest industrial manufacturing country.
Manufacturing industry is the main body of the national economy, the main battlefield of scientific and technological innovation, and the foundation of founding, rejuvenating and strengthening the country.
At present, a new round of scientific and technological revolution and industrial transformation characterized by the integration and development of the new generation of information and communication technology and manufacturing industry are stepping up in the global scope, which forms a historic intersection with the transformation and upgrading of China’s manufacturing industry.
Facing the problem of manufacturing industry being big but not strong, Made in China is speeding up its new journey towards “Made in China by Intelligence”.
Making great powers stand in the East
When New China was founded, the industrial base of our country was almost poor and white. Throughout the 70 years since the founding of New China, especially since the reform and opening up, a poor and backward agricultural country has grown into a major industrial manufacturing country in the world.
From low-end manufacturing represented by “three to one” to high-end global value chain represented by high-end equipment manufacturing industry, from “world factory” at the end of the industrial chain to “China Intelligent Manufacturing” of independent innovation, in the process of accelerating transformation and upgrading, Made-in-China has not only formed a complete manufacturing system. And the value added of manufacturing industry continues to grow.
According to the World Bank data, in 2010, China’s manufacturing added value surpassed the United States for the first time and became the world’s largest manufacturing country. Since then, China’s manufacturing added value has ranked first in the world for many consecutive years. In 2017, China’s manufacturing added value accounted for 27.0% of the world’s share, becoming an important engine driving global industrial growth.
Although China is a big manufacturing country, the manufacturing industry has been in the middle and low end of the industrial value chain for a long time. The low-end overcapacity coexists with the insufficient effective supply of high-end products. In 2015, the development plan of China’s advanced manufacturing industry described a grand blueprint for building a manufacturing power. With accelerating the deep integration of new generation information technology and manufacturing industry as the main line and promoting intelligent manufacturing as the main direction of attack, China has begun to accelerate the historical leap of manufacturing industry from big to strong.
“The background of the development plan of advanced manufacturing industry is that many developed countries have implemented the strategy of’re-industrialization’. With the rapid development of artificial intelligence, 5G, industrial Internet and other emerging technologies, intelligent manufacturing has become an important development trend of global manufacturing industry, which has a profound impact on industrial development and division of labor pattern, and promotes the formation of new production modes, industrial forms and business models. Accelerating the development of intelligent manufacturing is the only way to cultivate new momentum of economic growth and create new competitive advantages of manufacturing industry. Wang Xiaoming, a researcher at the Institute of Scientific and Technological Strategic Consultation of the Chinese Academy of Sciences, told China Economic Times.
Intelligent manufacturing has great application potential. Yang Yuanqing, chairman of Lenovo Group, once took Lenovo as an example to say that the intellectualization of manufacturing industry will not only be limited to the manufacturing sector, but also include the development, supply, manufacturing, marketing and service of products. For example, when developing a product in the past, we should talk to users about the impression of the product, and then improve it.
Now, there are thousands of data on the Internet, and all users’feedback can be analyzed through the application of big data, so R&D is more intelligent.
Innovation Enables the Future of Manufacturing Industry
Intelligent manufacturing is a strong demand for transformation and upgrading of China’s manufacturing industry. According to the sample survey, 73% of the 1815 enterprises in 10 cities in China have strong willingness to implement intelligent manufacturing.
According to the survey of intelligent manufacturing related projects, after the intelligent transformation of 308 projects in 2015-2017, the average productivity increased by 34%, the average operating cost decreased by 22%, and the average product development cycle shortened by 32.4%.
According to statistics, the funds for upgrading the technology of intelligent transformation in Guangdong, Jiangsu and Zhejiang have accounted for more than 70% of the local industrial investment.
China’s manufacturing enterprises are in different stages of development. Their digital transformation includes not only improving the information level of enterprises in the lower stage of development, but also realizing the digitalization, networking and intellectualization of enterprises in the higher stage of development. In recent years, China’s manufacturing industry digital transformation has achieved some results. The level of digitalization, integration and interconnection, intelligent collaboration has been continuously improved, and the scale of industrial Internet applications has been expanding. However, there is still a big gap from the requirements of the manufacturing powers.
Shen Hengchao, a researcher in the Innovation and Development Research Department of the Development Research Center of the State Council, has recently shown that problems such as lack of authoritative data standards, data security issues to be solved, data openness and sharing level to be improved, relatively weak technological base and information infrastructure, and severe challenges to employment still exist. It hinders the further deepening of the digital transformation of manufacturing industry. It is suggested that relevant departments should improve their support and encouragement policies, promote the construction and application of industrial data standards, strengthen data security protection, support key technology tackling, enhance the supporting capacity of information infrastructure, promote international cooperation, and achieve overall planning with reemployment training and social security system.
“China’s Internet economy, big data, Internet of Things, 5G, artificial intelligence and other development levels are on the same starting line as the developed countries in the world. The scale advantage of industry provides very good conditions for the application of digital, networked and intelligent technology. The transformation and upgrading of manufacturing industry has a very good foundation.
Generally speaking, the development of Intelligent Manufacturing in China is at the initial stage, and there is still a need for innovation and breakthroughs in key technical equipment, industrial software and system solutions.


Fugitive Zhang Shigang surrendered

The fugitive Zhang Shigang (male, Han nationality, born on September 11, 1972, Fenyang, Shanxi Province, ID No. 142321197209113114) is a suspect in the case of “11.25” extraordinary robbery excavating ancient tombs in Chengcheng County, Shaanxi Province, which was listed and supervised by the Ministry of Public Security. He is suspected of organizing the excavation of ancient tombs and selling important cultural relics. On December 16, 2016, the Chengcheng County Public Security Bureau of Shaanxi Province made a decision on the criminal detention of the suspect Zhang Shigang and pursued him online.
According to the report of Shaanxi Daily in January 2018, the “11.25” extraordinary robbery excavation of ancient tombs in Chengcheng County, Shaanxi Province is the most criminal gangs and the largest number of people involved in the excavation of cultural relics in the history of Chengcheng County, the highest level and the largest number of extraordinary robberies excavation of ancient tombs. According to the data provided by the police, after more than one year of investigation and arrest, eight criminal gangs of cultural relics were eliminated, 6.3 million yuan of stolen money was seized and frozen, 16 vehicles were seized and 402 stolen cultural relics were recovered. Among the stolen cultural relics recovered, there are 12 first-class cultural relics, 15 second-class cultural relics, 62 third-class cultural relics and 313 general cultural relics.
_The Criminal Investigation Bureau of the Ministry of Public Security introduced that the public security organs of Shaanxi Province have carried out a lot of work, such as groping, investigation and arrest, and arranged for the police to come to Zhang Shigang’s family members for legal and policy propaganda, urging them to surrender as soon as possible and striving for lenient treatment. Under the strong arrest offensive and policy pressure of the public security organs, at about 8:00 on September 18, Zhang Shigang surrendered himself to the Chengcheng police in Shaanxi Province who carried out the arrest work in Taiyuan, Shanxi Province. So far, the Ministry of Public Security has issued 32 A-level arrest warrants for cultural relics crimes since 2017.


2019 Future Science Award Winners Announced

The Scientific Committee of the Future Science Awards announced the 2019 winners list in Beijing on September 7. Shao Feng won the “Life Science Award” for his discovery of the receptors and executive proteins in the human cell for endotoxin LPS inflammatory response. Wang Yifang and Lu Jinbiao discovered the third neutrino oscillation mode in their experiments. New physics research beyond the standard model, especially explaining the asymmetry of matter and antimatter in the universe provides a possible contribution to the “Material Science Award”, Wang Xiaoyun’s innovative cryptanalysis method for her pioneering contribution in cryptography Revealing the weaknesses of the widely used cryptographic hash function, the achievement of the new generation of cryptographic hash function standards has been awarded the “Mathematics and Computer Science Award”.

Shao Feng, winner of the “Life Science Award”, recognized his receptors and executive proteins for the inflammatory response to the pathogen endotoxin LPS in human cells.

Humans and bacteria in the body coexist for a long time. Most bacteria coexist peacefully with humans, helping us digest food and even resist other harmful pathogens. How the body’s immune system distinguishes between beneficial and harmful bacteria and effectively initiates an immune response is an important issue in biological research. Over the past decade, Dr. Shao Feng’s lab has provided a systematic answer: they have discovered several cytoplasmic type recognition molecules (PRRs) that specifically recognize invading bacteria, revealing the distinction between pathogenic and non-pathogenic bacteria in host cell inflammatory responses. Molecular mechanism. The most important of these is the discovery that the inflammatory proteolytic enzymes caspase-4 and -5 are receptors for intracellular recognition of endotoxin LPS, a lipopolysaccharide of the cell wall of Gram-negative bacteria. Bacterial invasion of host cells can directly bind to inflammatory caspase 4/5 to activate cell death in cytokines and cognate patterns, and promote the release of cytokines into the bloodstream, causing an anti-bacterial inflammatory response. In addition, Shaofeng Lab and Vishva M. Dixit Lab also found that gasdermin D in the gasdermin protein family is the substrate for inflammatory caspase and the performer of cell dying. Based on the importance of cell death in the death mode of the host in the natural immunity of the host, Shao Feng’s findings provide a new way to explore the prevention and treatment of pathogenic infections and related diseases.

The winners of the “Material Science Award”, Wang Yifang and Lu Jinbiao, found that the third neutrino oscillation mode provides a possibility for new physical research beyond the standard model, especially to explain the asymmetry between matter and antimatter in the universe.

The Daya Bay Neutrino Experimental Cooperation Group led by Wang Yifang and Lu Jinbiao first discovered a new electronic neutrino oscillation mode near the Daya Bay nuclear power plant in Guangdong, China, and accurately measured their probability of disappearance due to oscillation. The experimental establishment of this oscillation mode indicates that neutrinos may destroy the joint symmetry (CP) of the parity and the positive and negative particles. Physicists generally believe that the existence of new CP destruction is a necessary condition for explaining the formation of matter in the universe far more than antimatter and the formation of the material world.

A neutrino is an elementary particle with a weak interaction that is released in nuclear decay and nuclear reactions. At the beginning of this century, scientists in Japan and Canada discovered two phenomena (or oscillations) between three neutrinos that are known to have a non-zero mass and existence that exceeds the current physical standard model of particles. Interacted and thus won the 2015 Nobel Prize in Physics. But the theoretical third oscillating oscillation is more interesting because it indicates that the neutrino oscillation has the property of CP destruction. But in the first decade of this century, physicists thought that the third kind of oscillation might be very weak or not. Despite this, particle physics experimenters in China, France, South Korea, and the United States have proposed experimental programs and launched a high-level scientific competition.

Wang Yufang and Lu Jinbiao found that the high-powered Daya Bay Nuclear Power Plant in China is the best experimental site in the world as an anti-electron neutrino source and used as a shield for underground laboratories. They organized and led the collaboration group to carry out a series of innovations, including the design and development of identical detector modules to eliminate systematic errors, the development of chemically stable cesium-doped organic liquid scintillators, and the highly sensitive cosmic ray detection system. This makes the Daya Bay neutrino experiment the world’s highest sensitivity. In March 2012, Wang Yifang and Lu Jinbiao on behalf of the Daya Bay International Cooperation Group announced the first detection of the third oscillation mode of neutrinos. A month later, the Korean RENO experiment confirmed this finding.

The establishment of the third neutrino oscillation indicates the direction for future neutrino experimental research. A new generation of international neutrino experiments, including the measurement of the quality order of the three neutrinos and the experimental plan of the neutrino CP destruction, were designed based on the results of the Daya Bay experiment. The experimental findings of Wang Yufang and Lu Jinbiao will have a profound impact on the future development of particle physics.

Wang Xiaoyun, winner of the Mathematics and Computer Science Award, rewards her pioneering contributions in cryptography. Her innovative cryptanalysis method reveals the weaknesses of the widely used cryptographic hash function and contributes to the new generation of cryptographic hash functions. standard.

Password hash functions are at the heart of most cryptographic applications and systems, such as data integrity verification and authentication, digital signatures, Secure Sockets Layer (SSL), information integrity, blockchain, and more. A cryptographic hash function is a function that hashes an arbitrary length of input into a fixed-length digest. The important attribute is that it is difficult to find a “collision” under the current computing power, that is, two different input hashes to Same abstract. If the collision of the hash function can be easily found, it means that the hash function is not safe, and all applications that use it will be considered unsafe.

Professor Wang Xiaoyun proposed a series of powerful cryptanalysis methods for cryptographic hash functions, special mode differential bit analysis. Her approach breaks through a number of previously accepted password hash function standards and revolutionizes how to analyze and design a new generation of cryptographic hash function standards. In 2004, Professor Wang Xiaoyun proposed the modulus difference bit analysis method and demonstrated how to find the real collision of the MD5 password hash function. This is an unexpected result for the password field, because MD5 is a very widely used cryptographic hash function that has withstood more than a decade of attacks from many cryptographers and found no collisions. In 2005, Professor Wang Xiaoyun and her collaborators extended the analysis method and attacked several other well-known hash functions, including MD4, RIPEMD, and HAVAL-128. In the same year, she and her collaborators published another method that could be further reduced in another paper to 269 operations to find another very widely used password hash function SHA in 263 operations. -1 collision. Although in 2005, due to the high cost, the actual attack on SHA-1 could not be performed. After 12 years, other scholars successfully ran the actual attack on the google cloud according to Professor Wang Xiaoyun’s method and found the real collision of SHA-1.

Professor Wang Xiaoyun’s work led to the phasing out of MD5 and SHA-1 hash functions in almost all software systems in the industry. Her work has driven and helped design the next generation of cryptographic hash function standards, including SHA-3, BLAKE2, and SM3. Professor Wang presided over the design of the Chinese national standard password hash function SM3. Since its release in 2010, SM3 has been widely used by Chinese software products.


Dam Collapse in India

A dam built on a canal in Jakarta State, India, collapsed less than 24 hours after it was officially opened, and it has been built for 42 years, costing nearly 22 billion rupees (about 2.2 billion yuan) and blaming the hole for the collapse.
The cost of building the dam has risen from 120 million rupees (about 12 million yuan) to nearly 22 billion rupees (about 2.2 billion yuan) since it was built 42 years ago.
It is reported that on the evening of August 28, the dam showed signs of leakage, less than 10 hours before it was officially opened. During the day, the Chief Minister of Jakarta, India, had just held a solemn ceremony to celebrate the dam’s official opening.
But no one expected that about 22 hours after the dam was opened, the dam collapsed and water overflowed from the breach, flooding the farmland of 35 villages in the Baghdad area near Giridi District.
Related departments blamed the accident on several blocked rat holes, but this statement was sped up by netizens.
Netizens said it was ridiculous to blame the “bean curd dregs project” on the rat hole.
At present, the government has set up an investigation team to investigate the incident in depth.


Arbor Day

This year’s Tree Planting Day, the head teacher decided to take us several spontaneously to visit an old man in the mountainous area of our city.
We gathered early in the morning, 桑拿佛山and the temperature was very different in autumn. We wore very thick clothes for fear of catching cold.
The road is tortuous, but also we have never stepped into the area, surrounded by mountains, one by one, continuous, are late autumn gray and yellow, occasionally a dark green, surrounded by thick fog, deep can not see anything, also very boring, there are only layers of mountains, except mountains, but only mountains.
After driving for about half an hour, we came to the foot of a mountain. After getting off, there was a mountain road with clucking feet. Next, we had to climb up. The road in front of us stretched up to the top, surrounded by tall trees like clouds, and the steps under our feet were covered with dead leaves. The front was dark, and we could not see clearly what was going on. Several of us pulled this hand hard on the scalp, and the winding road was still stretching. We went farther and farther. It goes deeper and deeper.
There was a silk in front of him, and after a few steps, there was a family in front of him. The head teacher told us that the three tiled rooms were the old man’s residence. I had seen him too. He was hunched with his back, grey hair, a white short sleeve and a grey cloth hanging on his shoulder. I don’t think he’s cold?
We trotted to him and shook hands with him one by one. What rough hands they were. We bowed politely, and the old man’s eyes narrowed with laughter. His gray and dry skin seemed to glow. He invited us in and said it was cold outside, and we went in. The furnishings in the room are very simple. There is only one wooden table and several low stools in the hall. The teapots and cups 桑拿广州are complete. The room is not very big, but it is narrow when we enter. But it was quite clean. We sat around and drank hot tea. The old man said that the tea was seldom opened by mountain springs. No wonder it was slightly sweet. It was the sweetness of nature.
After our understanding, the old man was a veteran. After retirement, he devoted himself to this vast mountain forest. He planted trees all the year round to prevent wind and fix sand. In the past ten years, he planted hundreds of thousands of trees and hundreds of trees by himself. Then he took us to see the trees he planted.
We came to another hilltop along the mountain road, listening to the head teacher, this winding mountain road is stepped广州桑拿 out step by step by step by the elderly over the years, which not only reminds me of Mr. Lu Xun’s famous saying: in fact, there are many people on the ground who have no way to go, but also become a road. But the old man was alone, so he stepped out of this hundred miles of tortuous road! _
At the top of the hill, there is a vast expanse of forest, a dark green, green black, autumn spring breath, there is a respectful admiration in my heart! The old man beside seems to be integrated with the green mountain, his brown pupil is deep green, his life, his body is blending with it. …
Farewell to the old man, we are again driving on the winding mountain road, where the gray yellow mountains and the old man’s Black Mountains blend, and in the middle is the back of the old man’s slight bow, rough hands…
