1. Chuan Arm China Joint Venture was established in April and named Arm mini China, a Chinese-owned company;
Set micro-network news, pass Arm scheduled to split the Chinese business in April, will establish a new company called "Arm mini China".
After the establishment of "Arm mini China", future IP licensing may adopt different pricing standards.
Japan’s Softbank Group acquired ARM, originally a British company, for £24.3 billion in July 2016 (now renamed Arm). Since the core business of Softbank and Arm is very different, together with the transaction-to-earnings ratio of up to seventy times, At that time shocked the global technology circle.
On May 14th last year, Arm signed an agreement with the Hou'an Innovation Fund in Beijing. The two parties intend to establish a joint venture company in Shenzhen. Arm provides intellectual property, technical support and training for chip design, but is controlled by the Chinese side.
At present, the market has announced that the Arm and Chinese-funded cooperation plan has been finalized. It is scheduled to cut the Chinese business in April and form a new company named "Arm mini China", in which Arm's shareholding will be lower than 50%, and China's fund holdings exceeds 50%. .
The market has announced that "Arm mini China" will be able to sell all Arm-owned IPs in China, but it may be divided into two sales and price models, which will increase the cost competitiveness of Chinese IC design companies. However, this part of the news has not yet been confirmed by Arm.
On January 24, 2017, the Hou'an Innovation Fund co-sponsored by China Investment Corporation, Silk Road Fund, Singapore Temasek, Shenzhen Shenye Group, Hopu Investment and ARM Co., Ltd. was formally established in Beijing. The fund has a scale of 800 million yuan. Dollars.
The Hou'an Innovation Fund is managed by Arm and Hopu Investment. The fund will combine Arm's global industrial ecosystem and focus on investment in mobile Internet, Internet of Things, artificial intelligence and other potential technology companies in key areas.
At the signing ceremony on May 14 last year, Houpu Investment and Chairman of the Hou'an Innovation Fund Fang Fenglei stated that the fund was established in January and that it had held several discussions with Softbank Group and ARM since April 12 and reached an agreement in Japan on April 12th. The agreement was approved by the National Development and Reform Commission and the Shenzhen Municipal Government.
According to Wang Yanhui, the secretary general of the China Mobile Alliance, apparently the ARM operation acquired by Softbank is more flexible. It is reported that Chinese funds of ARM China will be controlled. Although Chinese companies will share the profit margin of ARM in China, they will also receive strong support from the Chinese government. Support, ARM localization in the future will gain a broader space, and it will not rule out the possibility that it will be listed in China's IPO in the future. The establishment of a localized R&D team can lay the foundation for the future customization of local products, and it also explores a new era of autonomous control. The new model.
2. Quantum computers haven't fully realized Silicon Valley has already been open for quantum computing gatherings;
Netease Technology News March 17 news, According to foreign media reports, 'want to participate in the gathering of quantum computing?'
I didn't expect anyone to ask me this question. My brain is a bit overturned: Because just before I just ended an hour-long interview with Google quantum computing scientist Jarrod McClean, now I was thinking in my heart how to organize the article. Macleans's conversation drew my attention the day before the interview: He excitedly said a few words and said warmly, pointing out the relevant equations and charts in the slide. His The audience has a room of American physicists. This is the March meeting of the American Physical Society, and my main job is to write a newsletter for the world's largest physics conference. I was there to write for the organization's newsletter. Maclean told me that the first quantum computer algorithm will simulate complex molecular motions and eventually find useful new materials.
For the invitation to the party, of course I will participate. I think I can make some easy chats. Macleans flipped through his backpack and handed me a postcard with black ferrofluid splashing around. Above the drop, there is a line like this: 'Google Quantum Artificial Intelligence Party. On Thursday, March 8th, at 7:30pm, at the top of the Stade d'hotel.
This is undoubtedly the most glamorous physics gathering I've ever attended, and it's the same with non-physical standards. Surrounded by the Los Angeles skyline, there are two open bars on the terrace of the top floor of the Stade. The imitation plants made a cat-like look, and there was a messy snack. Next to the lazy couch, a small group of researchers squeezed around a laptop and were discussing the slides to be used the next day.
'This scenario was unthinkable five years ago,' said physicist Stephen Jordan. I met the Microsoft researcher near the elevator. 'We have no money and no consciousness.'
They are now conscious. Last year, giants of quantum computing such as Google, Intel and IBM released a new technology milestone every few months. In November, IBM announced a quantum computer with 50 qubits. Last week Google released a machine with 72 qubits. At the party, Google physicist John Martinis, who is responsible for the company’s quantum hardware division, told me that he thinks they are approaching 'quantum hegemony' - This means that they can quickly implement quantum algorithms that classical computers cannot achieve. Bristol University physicist Mercedes Gimeno-Segovia, technology companies and scholars hope Further improve these machines, and even discuss how to use existing chip manufacturing technology to build quantum machines.
A graduate student told me that he also participated in two luxurious gatherings on quantum computing in the same week — one organized by IBM and the other by the Rigetti company in the San Francisco Bay Area, which specializes in the development of quantum hardware. And software. Edward Leonard, a professor at the University of Wisconsin-Madison, pointed out: 'IBM used a cocktail named 'Entangled Gin' at the party. 'This wine means the mechanism of quantum computers. One's quantum entanglement. But, you know, it's the Sambucus liqueur instead of the superconducting circuit. 'The taste is good,' Leonard commented. 'Much like the gin's mixed with the taste of quinine water. . '
But the celebrations may be too early. At a meeting attended by about 11,000 people, several speakers pointed out carefully that the quantum computers can achieve a wide range of applications requiring about one million qubits—far more than Google’s 72 This is a well-recognized reason. At present, scientists are still testing the quantum computer working principle they developed, which means that they can only implement simple algorithms. For example, Google and IBM researchers have simulated hydrogen like this The motion of small molecules, of course, physicists have understood its principle of motion. Intel researchers are preparing to simulate specific phenomena that have been fully studied in a group of electrons. Maclean's algorithm requires the simultaneous use of quantum computers and classics. Computer to ensure accuracy.
I saw McLean at a glance. His hair was very prominent at the party. 'Have you seen performing artists?' He asked me. It is hard to ignore performers. A woman named Yozmit is using a deep voice for us. Singing the serenade, wearing a transparent helmet decorated with light-emitting diodes on the head. A deep, harmonic sound that made us serenade - wearing a clear helmet with LEDs. 'This party is in Hartmut's style. Maclean said, 'The performing artist is his private friend.'
Hartmut Neven was standing next to the bar. The physicist responsible for the Google Quantum Artificial Intelligence Lab was the organizer of the event. He specifically dressed up for the party: dressed Black jacket, slightly loose collar, colorful sneakers covered with spikes, there is a sunglasses above the forehead.
"I picked out some weird things that I think physicists would like to do." He told me with a hint of drunkenness that he constantly shakes a cocktail, 'This is why there is laser in the scene' -- he points to the projection on the wall -- 'And on-site analog music.' I found that someone in the corner was playing something that looked like a dual-tube electronic recorder. Another musician was playing an ethereal synthesizer sound.
'You should be very interested in this,' someone said.
Shimeno Segovia came towards me, and I asked her about party decoration. 'I think this should look like a quantum entanglement,' she said, pointing to the projection of the knotted line on the wall, It looks like a Windows 95 screen saver. On the other wall, it's like repeating a geometric projection like a kaleidoscope. 'I'm not sure what they have to do with quantum computing,' she said. 'You should go and interview Hart. Mut. '
Few people seem to understand the significance of this gathering. This is not much different from the conference itself. Physicists with Ph.D. admit that they can't really understand the jargon and the complicated speech. For this complex field, This is quite typical, ranging from quantum physics (understanding the principle of computer science) to engineering (how to develop quantum computers) to software design (processing big data).
So why are they so excited about quantum computing now? Quantum computers can take decades before they can be applied. Existing quantum computers cannot correct themselves. Microsoft designed quantum computers by an uncertain existence and No tiny objects are made up. They are also not sure what the benefits of quantum computers are, but quantum computers follow quantum mechanics and are completely different from the rules applied in current electronic devices. This means that it may be able to solve a series of fundamentally different The question of rules. At the very least, the party really translated this excitement into a language we all understand: An open bar. (晗冰)
3. Massachusetts Institute of Technology 'Human Body Chip': Simulating Organ Response to Drugs
March 16 news, MIT scientists have created a revolutionary new device that may completely change the way we conduct drug testing in the future. This book-sized device is called 'human body chip', It can hold up to 10 artificial 'human organs'.
Scientists have also created similar 'organ chips', 'biological cycle chips' and 'stem cell chips'. However, unlike those chips, the microfluidic device built by MIT can simulate several major drugs. The influence of vital organs, not the single organ of the liver.
According to researchers at the Massachusetts Institute of Technology, this microfluidic platform houses a variety of human cells and then lets liquids flow inside it to simulate blood flow. This microfluidic device is made of plastic and can simulate the circulatory system in the human body. The unit also contains a water storage device to limit moisture evaporation and maintain humidity, and a pump unit is embedded under the platform.
The latest version of the 'human body chip' device can integrate cells from 10 different organs, including liver, lung, intestine, endometrial, brain, heart, pancreas, kidney, skin and skeletal muscle. Scientists also It is able to precisely control the flow rate of molecular exchange and the distribution of drugs. This device can be used multiple times, and in the research conducted by MIT, the 'human organs' in this device was maintained for up to 4 weeks.
Research co-author Linda Griffith said: 'Our platform has the advantage of being able to scale up or down and adapt to many different configurations. I think it's just a transitional device and it will become more cost competitive in the future. Force, because the information you get will be more valuable. '
According to the MIT Technical Review magazine, scientists can use this device to track the response of different organ models to painkillers. Moreover, in the future, this device may allow scientists to no longer rely on animals such as rats for early detection. The drug test. In addition, drug testing on an organ model can also more accurately reflect the body's actual response to the drug because of differences in the size and composition of the animal's organs and our human organs.
Griffith puts it: 'When testing on animals, some of these effects are very unpredictable, because they are a bit special. With our human body chips, you can let the drugs disperse and observe the effects of drugs on organ tissues, and measure them. The speed of metabolism. '
According to researchers at the Massachusetts Institute of Technology, sometimes due to some differences in the patient's own medication, there will be complications, such as genetic differences, environmental effects, lifestyle and other medications taken. Griffith explained: 'A lot of time you Unable to find drug problems, only to be discovered on a large scale market.
This physiology chip created by MIT not only provides a new way for early testing of drugs, but it can also serve as a direction of improvement for similar devices on the market today. According to scientists at the Massachusetts Institute of Technology, in this device Before the advent of the world, no one could successfully connect many different organizations to the same platform.
In addition, most platforms are closed systems, which makes it difficult to control what happens in those platforms. In fact, this kind of human body chip device created by MIT is an open system that removes Lid and can allow scientists to easily manipulate or take samples for analysis.
