A Chinese Robot Has Performed the World's First Automated Dental Implant

Robots could soon be operating on you by themselves at the dentist clinic.

In China, a robot dentist installed two dental implants for a woman last Saturday, in what could be the world's first fully automated dental implant surgery,

the South China Morning Post. Human doctors supervised the whole procedure but did not actively intervene. The surgery, which took place in the city of Xi'an, was first reported by the state-run Science and Technology Daily.

Chinese universities climb world rankings as University of Tokyo slips to lowest position ever
(KYODO)
LONDON – Three Asian universities made the top 30 for the first time in an influential ranking of the world’s top 1,000 institutions released Tuesday.

The National University of Singapore moved up two places from last year to tie at No. 22 — its best ranking to date — while China’s Peking University climbed two spots to tie at No. 27 and Tsinghua University jumped five spots to reach No. 30, according to the Times Higher Education World University Rankings.

Britain’s Oxford University once again topped the list, now in its 14th year, with the University of Cambridge at No. 2 for the first time. The California Institute of Technology and Stanford University tied at No. 3.

The University of Tokyo, Japan’s top institution, fell seven places to No. 46, its worst-ever performance, with researchers attributing the results to a lower proportion of Ph.D.s, a worsening student-staff ratio and falling research productivity due to a decline in funding.

Next in line for Japan was Kyoto University, which tied at No. 74, up 17 places over last year. A total of 71 Japanese institutions were on this year’s list, 14 of which were new entrants.

“The rise of China in this year’s table is remarkable and demonstrates the way the global higher education landscape is changing,” Phil Baty, editorial director for global rankings at Times Higher Education, said in a statement. He noted that two Chinese schools were listed in the top 30 for the first time.

He added that East Asian nations will need to work hard to stay competitive as China “soars to join the global elite.”

Baty said the University of Tokyo’s continued decline is “a worrying trend” and called on the institution to “diversify its funding streams to remain a key global player in higher education.”

More than half of Japanese universities’ annual revenue comes from government expenditures, but national funding for higher education declined by 12 percent between 2004 and 2015, researchers said.

The comprehensive global rankings assess institutions on several factors including teaching, research, citations, international outlook and industry income.

One of China’s supercomputers, Tianhe-2, just received a major upgrade, nearly doubling its power. An announcement from the head of Matsuoka Lab, Satoshi Matsuoka, was made during the International HPC Forum (IHPCF) via a series of tweets. The upgraded computer now performs at a staggering 94.97 petaflops, or 949.7 trillion calculations per second, compared to its previous peak performance of 54.9 petaflops.
The upgrade came from replacing coprocessor chips installed in 2013 and replacing them with domestic chips. The 2013 installation used chips developed by Intel, called Knights Corner Xeon Phi coprocessors, and the original plan was to upgrade the system with upgraded Intel chips. However, the United States issued an embargo blocking the export of these chips to specific supercomputing sites, including the home of the Tianhe-2. In response, China was forced to begin building their own chips. They succeeded in matching the power of the Intel chips with the Matrix-2000 GPDSP accelerators.

It’s unlikely Tianhe-2A will come in at better than 70 or 80 petaflops on HPL.

The question is if the figure of 94.97 petaflops refers to rMax or rPeak. The description of "almost doubling" previous performance implies the latter, but it is not clearly stated.

The distinction is significant because if the figure is rMax it places it just ahead of world #1 TaihuLight, while if it is rPeak then the system remains in the #2 position.

EDIT: Ok it seems rPeak is a strictly theoretical figure while rMax reflects performance obtained using the Linpack benchmark used to create the Top 500 site/list.

EDIT2: Here is a more detailed article on the upgrade from the Top 500 site. Note that the upgrade is said to be underway, not yet completed:

If the upgrade has added 40 petaflops of rPeak performance, the performance increase alone is greater than the world's #3 machine (rPeak of 25 petaflops).

Also they keep saying that the competitor for exascale supercomputer is on between China, US and Japan.

I did some calculation and don't know if I'm right, if I'm wrong please correct me, judge by the peak performance, the current number one is at 125,435.9 (TFlop/s), or 125.44 petaFLOPS. And 1 exaFLOPS for exascale supercomputer is suppose to be 1,000 petaFLOPS, 1000/125.44 = 800% times more powerful.

And its widely reported that such computer will come online around the year 2020. But looking at the Top 500 performance change, at most it increase by like 50 exaFLOPS per year. I just don't see how in 3-8 years they can go from 20-50% increase year on year to ending up somewhere to 800% increase in just a few year from now.

Did I do my math wrong?

Most likely Rpeak. The interesting question is the power consumption with new indigenous CPUs ... I'd expect even less than 17 MW, so 2x efficiency
