News on China's scientific and technological development.

The China-made world's 1st whole-body magnetic resonance imaging (MRI) system with an ultra-high magnetic field as high as 5.0T debuted Wed at the European Congress of Radiology in Vienna, Austria, enhancing diagnostic accuracy with high resolution and signal-to-noise ratio..



These MRI machines are some one of the most advance machines has ever developed by Humans. the accuracy and precision are too complex that only few handful companies can produce. some says, these MRI machines second only to lithography machines in terms of complexity.

After years of research and development. Shanghai based firm called 'UNITED IMAGING' broke the foreign monopoly in this critical technology.

Really? India is top 3 in the world for advanced aircraft engines? Ahead of UK (Rolls-Royce) and France (Safran)? Iran is #5?

I'm willing to believe that China is ahead in a lot of areas, but that report is garbage.

They seem to be counting and weighting research papers. That's all well and good, but it omits several rather crucial intermediary steps between research papers and actually developing and producing something that functions, has real-world applications, is commercially viable, etc.

Is there any particular field or area of technology that you think China or a chinese company is working on or has made great progress in that's more or less a total secret to most of the world or even to China watchers? I'm thinking controversial fields like GMO babies or matters of absolute national secrecy like next gen weapon systems.

For the topic, I think China is making lots of hidden progress on GMO babies. I don't think that He Jiankui would have done what he did without some support from his University or colleagues, so there may be a University or group of researchers taking a look at what genes to edit to make someone smarter, taller etc and how to safety edit human embryos, even if they aren't doing it on mass. Having 3 of the only gene edited babies in the worlds to study has to account for something.

Well, it's pretty darn sure that they do have various next gen weapon systems under research/development.

Yeah but what kind? Conventional stuff of course, next gen fighters tanks etc etc. But weird weapon systems? One big surprise was nuclear reactors for ultra long range torpedos.

I mean you said total secret before, as for 'weird weapon systems', I don't know ¯\_(ツ)_/¯.

And I guess stuff like railguns or the 'rotating detonating engine' (or whatever it name was) also doesn't count.
Maybe Tengyun? The spaceplane (takeoff from airport, flies to nearspace releasing payload, flies back to airport)

Chinese researchers at Lanzhou University have developed a biodegradable shape memory polymer (SMP) using 4D-printing technology that is suitable for medical devices. The study results have been published in the journal of Materials & Design..

regardless of India. Most studies that try to gauge who's ahead in science (US v China) China pretty much always ends up at the top by a good margin. It is clear by now that China has surpassed the U.S in science. And China still isn't even close to utilizing its human capital to its full potential. The U.S is royally fucked, doomed to irrelevance in the future just as the Europeans are. They thought they didn't need manufacturing since they could just r&d the technology, but China has come and shown that they can not only hold on to their manufacturing but dominate science r&d as well. China just beat the U.S, who is giving it their all, while not even trying all that hard.

Huawei Releases an Upgraded Engineering Simulation Solution at MWC 2023​

According to news from the micro-network, Huawei's official website recently revealed that the company demonstrated an upgraded version of the engineering simulation solution at the 2023 World Mobile Communications Conference (MWC), which is oriented to the manufacturing industry and provides key ICT infrastructure solutions such as data center computing, storage, and switches. plan. Provide powerful computing power and innovative software and hardware to help manufacturers accelerate product development.

According to the article, computer-aided engineering (CAE) simulation is critical for research and design (R&D) optimization. High Performance Computing (HPC) provides CAE with powerful computing capabilities and accelerates development. However, there are some challenges with using CAE. Including multiple data transmission, high concurrency, and complex scenarios.

Huawei has a deep understanding of the key role of simulation in R&D based on its deep manufacturing experience, and the company also has extensive experience working with automotive customers who rely on vehicle crash testing, fluid dynamics, electromagnetics, and structural simulation in their manufacturing processes.

Liu Chao, CEO of Huawei Manufacturing Corps, said that the diversity of the automotive industry means that simulation technology must adapt to a wide range of solving algorithms and resource requirements. This is why Huawei provides a flexible scheduling system for CAE simulation. Users can manage multiple clusters through one system, enabling more efficient cluster management by dragging and dropping applications. The system supports integrated design and calculation, and HPC can be used to complete data preprocessing, calculation and post-processing simulation without leaving the data lake.

Huawei also provides open hardware capabilities and high-bandwidth Converged Ethernet Remote Direct Memory Access (RoCE) networking to build a high-performance computing network with zero packet loss. This enables more efficient computing than InfiniBand. The high-density storage capacity density is 2.67 times that of other products. In terms of computing, mainstream industrial software can be integrated through transcoding. (Proofreading/Chen Xinghua)

中新网北京3月2日电(李坚 张素)春回大地，各地民众出行需求增多，许多人发现家门口的道路开通了“绿波带”。据知，运用“北斗高精”一体化精准定位导航技术，地图红绿灯倒计时功能已在多个城市陆续落地、持续升级。

记者近日使用该地图功能发现，当信号灯即将变灯时，地图语音播报会发出提醒，方便驾驶人员提前减速。而当车辆距离路口约200米远时，导航系统还会结合车辆行驶情况给出建议车速区间。

“路口事故多发，如果碰上雨雾天气、前车视线遮挡等突发状况，驾驶人员可能无法看清前方红绿灯变化，猛踩刹车或启动不及。抢灯、闯灯还可能引发交通事故。”百度地图相关负责人2日受访时说，此次在“北斗高精”技术加持下，红绿灯倒计时功能进一步升级，支持“绿灯读秒”，他们还面向全国升级了“绿波车速”功能。

这位负责人介绍说，通过与30余个城市的交警部门开展合作，目前已在全国上线600多条“城市绿波带”。此举旨在提升用户驾车出行体验，助力缓解交通压力并营造安全、有序、畅通的道路交通环境。

据知，借助“互联网+地图+信控”等技术，多地已有成功实践。例如在湖南省株洲市天元区，以“绿波带”为核心，该区域拥堵指数下降13.4%，平均车速提升9.7%。

此外，在陕西省西安市，全城已上线近2000个“红绿灯倒计时”，近200条“绿波带”，市民通行效率得以提升。

研发团队表示，接下来将继续发挥在大数据、云计算和人工智能领域的技术优势，联合各方共同为广大民众提供安全、高效的出行服务。(完)
