China launches third prototype exascale computer
Xinhua| 2018-10-22 19:29:28 http://www.xinhuanet.com/english/2018-10/22/c_137550589.htm

China has launched a third prototype exascale computing machine, the next-generation supercomputer, according to the developer.

The Shuguang exascale computer is expected to be put into operation in national supercomputing centers in Shanghai and Shenzhen, said its developer Dawning Information Industry Co. Ltd.

An exascale computer is able to execute a quintillion calculations per second. In China, prototypes are being developed by three teams led by the National Research Center of Parallel Computer Engineering and Technology (NRCPC), Dawning Information Industry, and the National University of Defense Technology (NUDT).

With Shuguang's launch, the three developers have all launched prototype exascale computing machines, marking a further step toward China's successful development of the next-generation supercomputer.

"The launch of a prototype exascale computing machine helps researchers test and improve key technologies through trial and error, and clear obstacles for the final computing system," said Zhang Yunquan, a researcher with the Institute of Computing Technology at the Chinese Academy of Sciences.

A great day for China The chief himself open the bridge a marvel of engineering via Adam Wang
It is also a political statement Hongkong invariable will be drawn to Guangdong kicking and screaming notwithstanding, All hat to the builder and worker who build this marvel. That is what a country on the rise normally do. They build monument instead of bitching and blaming everybody else
Look how he smile. Like they say the first emperor built a dynasty, the second one consolidate the empire, the third one preside over prosperity and greatness

ZHUHAI – President Xi Jinping announced the opening of the Hong Kong-Zhuhai-Macao Bridge at an opening ceremony in the city of Zhuhai, Guangdong Province, on Tuesday morning.

Leading officials from Guangdong and the Hong Kong and Macao special administrative regions attended the 9 am ceremony, which takes place at the passenger clearance building of the Zhuhai Port.

There were hundreds representing the roughly 50,000 construction workers and engineers from the Chinese mainland and Hong Kong and Macao SARs who built the mega bridge, including leading engineers and designers.

Representatives of bridge operators from the three cities also attended the grand opening. These include HZMB Authority, immigration and customs officers from the ports in Zhuhai, and in the Hong Kong and Macao SARs.

The 55-kilometer bridge-island-tunnel complex, the first sea span across the Pearl River Estuary linking its west and east banks, becomes the premier sea-crossing in the world.

The bridge is the result of five years of feasibility research and another nine years of construction. The mega cross-boundary complex officially opens to traffic at 9 am on Wednesday.

Looking ahead, the bridge is expected to strengthen trade, financial collaboration, logistics and tourism among the three places.

It will bring residents in Hong Kong, Macao and Guangdong within a "one-hour living circle", which is expected to attract more visitors to the Guangdong-Hong Kong-Macao Greater Bay Area.

All those accusation of technology stealing is bogus just pretext to impose trade war unilaterally
Zhao Zisen, an 86-year-old engineer recalled how his team developed #China's first optical #fiber in the late 1970s, with no research project, no money or even a lab.
If you improve education, put resource in science and technology. rewarded and appreciate technical people then you will advance technology, industry It happened with fibre technology It will happened with semiconductor too

It is bound to happened sooner or latter There is no respect for STEM education in the west and media instead they glorified actor, sport jock, movie star,reality TV, 6 pack ab. What do you expect via Haidan. There are roughly 4 million STEM graduate in China every year and only 600,000 in US mostly 1/3rd Asian too BTW
Numbers of science papers and numbers of international students suggest this may be the beginning of the end of the American century.

China surpasses U.S. in science papers
  • John Richard Schrock Emporia
  • Oct 22, 2018
China has surpassed the U.S. in the number of articles in science journals. This is not unexpected; Chinese authorship was on a sharp upward slope while U.S. authorship has declined slightly each year.

According to a just-released report in Learned Publishing that analyzed numbers from our National Science Board, U.S. scientists published 409,000 science, technology and medical papers last year while China published 426,000. This takeover has been swift and China’s momentum will rapidly leave the U.S. behind, the analysis indicated, since the “number of science and engineering articles in all fields from China increased nearly fivefold from 2003 to 2016.”

Nature Index counts the number of authors by country in Science and Nature, and we are only a few years away from China overtaking the U.S. in authorship in these premier international journals.


While Chinese university professors are the lowest paid among the developed nations, they receive additional payment for additional duties, from presiding over final graduate defenses to publishing papers in prestigious journals. And a paper accepted in Science or Nature can earn a Chinese professor an extra one million Chinese yuan bonus, about US $150,000.

China also supercharged its new faculty with overseas training. In their top tier universities, to achieve rank of professor requires that they have studied somewhere in the West — Australia, New Zealand, Europe, the United States — for a year. When they return having learned state-of-the-art research techniques, many are then provided with state-of-the-art research equipment. This long-term policy and investment in education and people has paid off in accelerating science advancements in China. Simply, the U.S. spends huge amounts on military and relatively less on education and research. China has done the complete opposite.

When Deng Xiao-ping opened up China in the 1980s, he made English the second language for students to study, due to its predominance in trade and science. It took a long time for China to build English capacity, with English starting in elementary schools across the country. And English has been a major part of the high school exit test that determines who goes to college. This bilingual policy is now paying off with young Chinese scientists reading and publishing research in English.

China still has a way to go. It remains second to the U.S. in R&D (research and development) spending according to the latest issue of Science, at $254 billion or a 12.3 percent increase over the prior year. In 2012, China’s R&D level was 34 percent of the U.S. R&D. But by 2016, based on “purchasing power parity,” China’s R&D spending was equivalent to 88 percent of U.S. spending and will likely surpass the U.S. soon. China’s budget for basic research hit US $14.1 billion, up 18.5 percent over the prior year.

It has also helped that the United States has failed to move ahead in many areas of science, from particle accelerators to astronomy to organismic biology. Two years ago I watched in the insect museum here in west-central China as new insect cabinets and drawers were brought in, a 56 percent increase in museum capacity. At this very same time, the U.S. N.S.F. had placed a moratorium on American museum funding nationwide for a half year. Today, specialists from the British Museum and Illinois Natural History Survey come to the museum here in China that now houses the world’s leading collections for several major groups of insects. Meanwhile, the number of entomology departments in the U.S. today has dropped to barely half the number 20 years ago.


When it comes to number of active researchers, China is second in the world after the European Union. (The U.S. is third.)

According to a report in University World News, the “European Commission is ‘keeping a very close eye on China,’ particularly in the area of innovation....” The EU “realises it [the EU] has a performance lead, but that is decreasing very rapidly because China has improved seven times faster than the EU” in performance indicators.

Asian international students — currently there are over 350,000 currently attending U.S. universities — generate a substantial revenue flow to the U.S. America also relies on some Asian graduates staying to fill our vacancies in engineering, physics and chemistry where there is a shortage due to our very low K - 12 science education requirements.

Students here in China watch the news and several have already asked me whether they will still be welcomed in America. Anything positive I can offer would soon be drowned out by another tweet from the White House. We are already seeing the beginning of a downturn in international students coming to the U.S., as they divert to Australia, Canada and other friendlier countries. Numbers of science papers and numbers of international students suggest this may be the beginning of the end of the American century.

The western world can turn that around though. STEM is admired albeit within smaller circles. STEM is important but it's definitely not everything. There are many other things a nation needs to consider. Worshiping celebrities and artists is not a permanent thing and a balance will come about soon enough.

There are already programs pushing STEM to children and efforts will only increase as it becomes obvious there are quite a few international challengers. The move away from STEM was mostly due to the west gaining an incredible quality of life compared to the rest in the last century. This is already no longer the case as Japan and SK have been most successful in displacing many industries and equalising distribution of wealth. I doubt they'll wait until India poses another huge threat before going STEM focused like China is at the moment. More STEM players is actually a good thing for the world if peace if kept.

China Focus: High-orbit BeiDou-3 satellite boosts China's global navigation system
Xinhua| 2018-11-02 01:47:35 http://www.xinhuanet.com/english/2018-11/02/c_137575261.htm

China's home-grown global satellite navigation system came a step closer to completion with the launch of another BeiDou-3 satellite at 11:57 p.m. Thursday from the Xichang Satellite Launch Center, in the southwestern Sichuan Province.

Launched on a Long March-3B carrier rocket, it is the 41st of the BeiDou navigation system, and will work with 16 other Beidou-3 satellites already in orbit.

It is also the first BeiDou-3 satellite in high orbit, about 36,000 km above the Earth. In a geostationary orbit, following the Earth's rotation, it will view the same point on Earth continuously.

A basic system with BeiDou-3 satellites orbiting will be in place by the year-end to serve countries in the China-proposed Belt and Road Initiative, said Yang Changfeng, chief designer of the system.

The satellite and rocket for Thursday's launch were developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology, respectively. The launch was the 290th mission of the Long March carrier rocket series.

Apart from radio navigation system, the satellite is equipped with an improved radio determination satellite service that can provide short message services to 10 million subscribers each hour.

With an advanced satellite-based augmentation system, the satellite can also provide low-cost and reliable navigation services to civil aviation clients at home and abroad.

"If a navigation signal went wrong, the satellite could inform users within 6 seconds to switch other signals," said Pan Yuqian, chief designer of the BeiDou-3 series.

The satellite is carrying hydrogen and rubidium atomic clocks, which will play a key role in positioning and timing accuracy.

Atomic clocks are the most accurate time and frequency standards. They use vibrations of atoms to measure time. An accurate and ultra-stable set of atomic clocks is essential for global navigation satellite systems.

The clocks are 10 times more stable than those used in previous BeiDou satellites, according to scientists.

World's first AI news anchor unveiled in China

China’s state news agency Xinhua this week introduced the newest members of its newsroom: AI anchors who will report “tirelessly” all day every day, from anywhere in the country.

Chinese viewers were greeted with a digital version of a regular Xinhua news anchor named Qiu Hao. The anchor, wearing a red tie and pin-striped suit, nods his head in emphasis, blinking and raising his eyebrows slightly.

“Not only can I accompany you 24 hours a day, 365 days a year. I can be endlessly copied and present at different scenes to bring you the news,” he says.

Xinhua also presented an English-speaking AI, based on another presenter, who adds: “The development of the media industry calls for continuous innovation and deep integration with the international advanced technologies … I look forward to bringing you brand new news experiences.”

Developed by Xinhua and the Chinese search engine, Sogou, the anchors were developed through machine learning to simulate the voice, facial movements, and gestures of real-life broadcasters, to present a “a lifelike image instead of a cold robot,” according to Xinhua.

The broadcasters made their debut during China’s annual World Internet Conference, an event meant to be China’s Davos for the tech sector as well as a platform for China’s vision of the internet.

While China is home to some of the world’s largest tech companies and some 800 million internet users, its internet is one of the most controlled in the world. Observers worry China is turning into a digital police state, with technology from iris and gait recognition being deployed to monitor activists, ethnic minorities in places like Xinjiang, and regular citizens.

According to Xinhua, the AI technology is not limited to news presenting. The systems can be customised to different clients in other industries. Wang Xiaochuan, the head of Sogou, gave the example of a popular book reading app, Uncle Kai. “In the future, it could be your parents telling the story,” he said in an interview.

For Xinhua’s already tightly-scripted and controlled state news presenters, the AI anchors take things a step further. Video of the Chinese anchor quickly spread on social media in China, with many viewers impressed as they were alarmed. “A little bit horrible,” one said, to which another responded: “Really scary.”

While praising the anchors, Xinhua and Sogou acknowledged their limits. “I, who was wholly cloned from a real-life host, have mastered broadcasting as well as the real host,” the Chinese-speaking AI anchor said. “As long as I am provided with text, I can speak as a news host.”

"The share of TOP500 installations in China continues to rise, with the country now claiming 227 systems (45 percent of the total). The number of supercomputers that call the US home continues to decline, reaching an all-time low of 109 (22 percent of the total). However, systems in the US are, on average, more powerful, resulting in an aggregate system performance of 38 percent, compared to 31 percent for China."

this sounds cool (link is in the post right above):

"Tianhe-2A ... was upgraded earlier this year by China’s National University of Defense Technology (NUDT), replacing the older Intel Xeon Phi accelerators with the proprietary Matrix-2000 chips."
