Chinese, American scientists have sequenced and analyzed a portion of genomes of over 140,000 pregnant women in China, the largest-scale genetic analysis of Chinese people to date, revealing associations between genes and birth outcomes, including the birth of twins and a woman's age at first pregnancy.

The study published on Thursday in the journal Cell also allowed researchers to reconstruct the intermarriage of different ethnic groups in China, and promised to help identify genes that make people susceptible to infectious diseases.

Researchers from BGI-Shenzhen used data from non-invasive prenatal testing (NIPT) to sequence randomly 6 to 10 percent of each mother's genome.

"Although non-invasive prenatal testing is low-pass sequencing," said the study's co-senior author Xu Xun from BIG-Shenzhen, a genome sequencing center in China. "There's still a chance that using this data with a large population size will help us to have a much broader vision of what the Chinese genetic population looks like."

NIPT, a test that sequences small amounts of a mother's cell-free DNA to screen for fetal trisomy, has been growing in popularity in China. It has been administered to approximately 6 to 7 million Chinese women.

They found that the variation in a gene called NRG1 was linked to a greater or lesser incidence of twins. One variant of the gene is more common in mothers with twins and is associated with hyperthyroidism.

A variant of another gene, EMB, was associated with older first-time mothers, according to the study.

Also, the DNA sequencing in maternal blood revealed links between viruses and genes that determine susceptibility to disease. A variation in one gene was associated with a higher concentration of herpesvirus 6 in a mother's blood.

Herpesvirus 6 is the most common cause of the relatively benign baby rash called roseola, but a high "viral load" correlates with more severe symptoms. People with Alzheimer's disease also have higher levels of herpesvirus 6 in their brains.

"It's amazing that this is even possible that you can take these massive samples and do association mapping to see what the genetic variants are that explain human traits," said co-author Rasmus Nielsen, a professor of integrative biology at the University of California, Berkeley, who oversaw the computational analysis performed by researchers at BGI in Shenzhen, China.

The study looked at 141,431 participants including 36 of China's 55 ethnic minority groups.

"We're excited about the volume: our participants represent 1/10,000 of the Chinese population, so it really is large sampling and a good reflection of the entire population," said co-senior author Jin Xin with BGI-Shenzhen and South China University of Technology.

This is a low-pass, rather than whole, genome sequencing but from many individuals which is cheaper to get but can still tell a lot, according to the researchers.

Their proof-of-concept analyses allowed scientists to identify patterns in the evolutionary history of China's different ethnic groups, to pinpoint novel genetic loci linked to phenotypes like height and BMI, and to identify viral DNA distributions specific to the Chinese genome.

The researchers also found that many Chinese had genetic variants common among Indians, Southeast Asians and, along the route of the ancient Silk Road, Europeans.

Now, BIG-Shenzhen is analyzing the genomes of one million Chinese women who underwent non-invasive prenatal testing.

Gree Sets Up Semiconductor Unit to Help China Make Chips at Home

(Yicai Global) Aug. 22 -- Chinese appliance maker Gree Electric, best known for its air conditioners, has set up a CNY1 billion (USD146 million) chipmaking subsidiary after several claims that it would enter the semiconductor business as the country looks to reduce reliance on imports.

Gree is the sole shareholder in Zhuhai Zero Border Integrated Circuit, while the new unit’s legal representative is Dong Mingzhu -- Gree’s chair and one of China’s most successful businesswomen -- according to data from the National Enterprise Credit Information Publicity System. The firm’s registered business scope covers a broad range of areas, including chipmaking, the Internet of Things and software for mobile devices.

The firm announced in April that it would not pay out dividends for 2017, the first time in over a decade. Instead, Dong told shareholders that the company would be using the profit to foray into other sectors, particularly chipmaking, in which Dong said she was prepared to invest as much as CNY50 billion -- or more than double last year’s net income.

Semiconductors have been a hot topic in the world’s second-largest economy after the United States reprimanded one of China’s biggest telecoms equipment makers, ZTE, in April for illegally selling American technology to Iran and North Korea and failing to punish employees behind the scheme.

The US forbade domestic companies from selling technology to the firm, bringing ZTE to a standstill until American lawmakers lifted the ban after US President Donald Trump stepped in. ZTE may have escaped the ordeal, but the debacle highlighted major holes in China’s domestic chip development.

In order to nurture its own semiconductor unit, Gree plans to quadruple revenue to CNY600 billion (USD87.7 billion) within five years, Dong said in June, adding that by 2019 she expects all of the company’s air conditioners to be using its own chips. The half-decade goal might seem farfetched, but income soared 45 percent annually to CNY150 billion in 2017, with air-con sales making up about 82 percent of all revenue. If it wants to hit the target, it will need income to increase by an average of just under 32 percent a year.

    Thanks x 3
This lady works fast! I confess that I was a little bit skeptical, in a way. It depends how it's done. My sense is that she should structure the company so that she can also sell to Haier, Hisense, Midea, TCL and whoever else, because scale in this industry is important. Also, if the fabrication is outsourced, it should be to somebody on the mainland, so that the production equipment sector can also benefit. It can be SMIC, Huali, or whatever, or she can buy her own equipment. Anyway, she doesn't seem to need my advice! :D


It is amazing 30 year ago there is only 1 subway in Beijing now even 2 bit cities have subway
With even more country fold move to the cities they did the right thing by planning ahead instead of waiting until congestion and traffic jam hit the cities even though traffic jam is common occurrence in Chinese cities now

High-riding bonanza on China’s ever-growing metro lines
31 cities across the country had urban rail lines in service as of first half of 2017, with Shanghai boasting the world's largest system

Shanghai media reported that throughout the seven-day National Day break, tens of thousands of builders continued to work flat-out dozens of meters beneath the city’s bustling streets to install giant concrete walls for new tunnels. They were in a bid to ratchet up the construction of a new metro line that will wriggle deep through the city’s alluvial soil bed to connect four outlying districts.

The 43.8-kilometer Line 18 will be the latest addition to Shanghai’s already sprawling cobweb of subway lines. Already, at a system length of 728km, the Shanghai Metro is second to none across all cities worldwide.

A series of projects will add no less than 160km to the web by the end of 2020. One fact to note is that Shanghai is a latecomer to the urban-rail club: The Metro did not have its first line until 1993.

Challenges have emerged. New lines must be dug as deep as a 15-story building to squeeze under the maze of existing tunnels, Zhou Xisheng, an engineer with the system’s operator Shanghai Metro Group, told Agence France-Presse.

Chinese cadres share the consensus that digging more rail lines in their cities provides the conduit for not only the flow of people but also for capital, expertise and opportunities. Boosting an extensive urban rail network is also a status symbol of being a genuine metropolis.

The Beijing Subway now has a total length of 608km, while the corresponding figure for Guangzhou, the largest city in southern China, which inaugurated its first line in 1997, is 400km, and the bourgeoning trading hub is on track to outstrip New York City in total length of urban rail in active service.

Once reserved for megalopolises, subways are also running in lower-tier cities and their conurbations far inland amid China’s sweeping urbanization.

Thirty-one cities throughout China, including almost all provincial capitals and affluent prefecture-level cities, have launched subway networks, with 133 lines and a combined length of 4,400km in operation as of the first half of 2017, and a dozen more embarking on ambitious construction initiatives.

Cities such as Chengdu, Wuhan and Zhengzhou have put forward plans to expand their systems beyond the 500km mark.

With the construction spree forging full speed ahead, it is reported that boring machines and tunneling shields, as well as train drivers, are in short supply.

Xinhua reported that China would fork out 2 trillion yuan (US$295 billion) on subway construction between 2016 and 2020, and despite the hefty outlay on top of mounting government debts, the Communist Party’s support should still able to see this litany of projects through.

Party cadres are asked to be more forward-thinking when planning new rail lines for many decades to come for urban agglomerations.

The metro networks of these cities are also riveted, through key transportation hubs, to the nation’s 25,000km network of express railways that is still expanding at full speed.

For instance, the 370,000-square-meter Guangzhou South Railway Station is a key node straddling seven high-speed rail lines and is also served by four metro lines to the city’s downtown area as well as neighboring cities in the Pearl River Delta.

This year, the National Development and Reform Commission (NDRC), China’s top economic regulator, signaled a red light when even some counties were eager to jump on the metro bandwagon.

Thresholds for approval, inducing gross domestic product, fiscal income and size of population, were raised to cap the debts raised to finance new projects.

Cities like Lanzhou in Gansu province and Baotou in Inner Mongolia that had been eager to build their first metro lines were among the first to hit the regulatory roadblock.

Yet before long these cities saw light at the end of the tunnel after the NDRC made a U-turn within just a few months and tacitly scrapped the heightened prerequisites for launching new projects.

This is the result of policymakers resorting to the old path of infrastructure investment to drive growth when the Chinese economy shows signs of running out of steam.

that's what amazes me about China I mean several-million towns I couldn't place on a map

I checked and the place I've heard of nearest to Ningbo is Zhousan

wondering if that area (Shanghai and to the south) becomes a supercity with like one-hundred million people LOL

Arm server chip exposure

Recently, Huawei officially disclosed its new generation of Arm server chip Hi 1620.

According to informed sources, the semiconductor industry observers, Huawei's Arm server chip is designed independently based on the Arm V8 architecture, using the most advanced 7nm process in the industry. It is understood that Huawei provides 32, 48 and 64 core versions on this chip, up to 2.6/3.0Ghz, and can support PCIE 4.0 & CCIX.

Huawei said that this is the industry's first 7nm Arm server chip supporting PCIE4.0. From Huawei's PPT, we can see that the Hi 1620's 48-core version of the CPU and Intel Skylake 8180's SPECint performance is equivalent, but in terms of power consumption will be 20% lower than the latter.


Huawei Hi 1620 details

As a wide-ranging enterprise, Huawei's Arm server chip has been developed for many generations.

As you can see from wikichip, in 2015, Huawei introduced its first-generation Arm server chip Hi 1610. The 16-core chip designed with Arm Cortex-A57 can only achieve 2.1Ghz.

In 2016, at the China Twelfth Five-Year Innovation Achievement Exhibition, Huawei exhibited its first ARM platform server “Taishan”, equipped with a self-developed ARM architecture 64-bit processor “Hi1612”, built using TSMC's 16nm process. , compatible with ARMv8-A instruction set. Huawei said that in addition to the storage unit, the processor has complete independent intellectual property rights and can be applied to big data analysis, shared cloud, information search and other fields, and has been tested in Alibaba.

In 2017, Huawei introduced the HI 1616. The 32-core chip designed with Cortex-A72 has a maximum frequency of 3Ghz and then this year's Hi 1620. It can be seen that although Huawei has not publicized its Arm server chip, it has maintained an annual update frequency in the past few years.


Huawei Arm server chip series

Considering the influence of Huawei itself in mobile phones, cloud and storage, the arrival of this Arm server product is a further improvement of its own industrial chain for Huawei itself. Can provide customers with customized, comprehensive and controllable one-stop service.

Zooming into the entire Chinese integrated circuit industry, Huawei's product line may be able to take a new path in the server chip market that Intel controls. But there is no doubt that this will face challenges from multiple competitors at home and abroad.


Arm server chip market

In recent years, with the increasing market share of Intel server chips, the rise of domestic independent controllable demand, Marvell acquired the establishment of Cavium, Huaxintong, Qualcomm's fading out, and the Arm server chip market has been surging. Although some people are withdrawing from the beginning, under the impetus of Arm, there are also new players entering this market. Huawei is one of them. As mentioned above, from the perspective of Huawei's business, the Arm server chip business is a supplement to the industry chain for them.

In addition to Huawei, domestic Feiteng, Huaxintong, and American Ampere are also important players in the Arm server market.

First look at the Feiteng aspect.

Earlier, Dou Qiang, the chief scientist of Tianjin Feiteng Information Technology Co., Ltd., mentioned in an interview with the media industry observation that Feiteng launched the Feiteng FT2000+ processor in 2017. The chip built using the 16nm process has 64 cores and main The frequency can be 1.8-2.3GHz, and the measured performance of the standard spec test is comparable to that of the Intel Xeon processor introduced in 2013. Feiteng also completed the work related to server storage, database and middleware adaptation.

In Dou Qiang's view, the performance of this processor is quite different from that of Intel's products. Even their products are single-channel design, which cannot meet the large-scale design requirements. But Feiteng will expand it two or even eight in the future to match the processor needs of high-end servers.

Gu Hong, general manager of Feiteng, said before that Feiteng's CPU is based on ARM technology architecture, but the code part including CPU calculation module is independently developed by the company for many years. This allows Feiteng to have higher autonomy in the autonomous control of this series of products.

I came to Huaxintong, a company jointly established by the Guizhou government and Qualcomm, focusing on the Arm server chip.

According to a report by Phoenix Technology in May this year, Huaxintong's first server chip, “Huaxin No.1”, has been successfully produced at the end of 2017 and will be launched in the second half of this year. The second generation product they developed, "Huaxin No. 3", is currently under development.

According to reports, this server chip has only half a bank card, integrating about 1 billion transistors and more than 2,800 pins, and the chip process is 10 nanometers. The built-in independent security module greatly enhances the chip safety factor, which is a highlight of "Huaxin No. 1". It can be applied to high-performance computers to play the role of processing large amounts of data quickly and in a timely manner.

As for Ampere, it was founded by former Intel executive Renee James. In an interview with Ms. James before the semiconductor industry observation, she mentioned that Ampere's core team mostly comes from chip giants such as Intel and AMD. Most of the company has very rich experience in server hardware and software, they are on the server. The understanding of chips and software is quite deep, which makes them an emerging force in the field of Arm servers.

In September of this year, Ampere introduced the 16nm process processor built by the company's first 64-bit Armv8-A architecture for the data center. Their 32-core Armv8-A processor is designed in Turbo mode. The frequency is up to 3.3 GHz. The processor has been chosen by Lenovo and several other original design manufacturers (ODMs).

According to them, this processor has excellent total cost of ownership (TCO) value, powerful computing performance and memory capacity, and rich I/O to handle cloud workloads, including big data, web tiers, and in-memory databases. .

Ampere also announced future multi-generation product roadmaps, including next-generation 7nm products. The product will offer single-socket and multi-socket options and will be available in 2019, which will be used for future ultra-large-scale cloud computing and edge computing.

As can be seen from the above, Huawei's leading edge in the Arm server chip is ahead of its global competitors.

to sum up

Although Huawei's Arm server chip has so far dominated, we can see that Intel's server ecosystem, which has been built for decades, cannot be shaken. However, Huawei relies on its chip design experience accumulated over the years, and has been in the field in the past year. Coupled with Huawei's own accumulation of AI chips, ISP chips, mobile phone SoCs and other various chips, terminals and applications, Huawei will play an important role in the Arm server market in the future.

As for the future, it depends on how Arm combines the major chip suppliers and software vendors to work together in this field.
