Ah isn't this facility use the battery tech bought from a US lab? The one that made internet seething.
Very unlikely. DICP of CAS owns the technology. DICP was the lead author of the first ever flow battery international standard. It has more than 200 patents (including patents pending) on the IP.

Chinese researchers have recently completed the trial deployment of a deep-sea in-situ scientific experiment station in the South China Sea, bringing them one step closer to realizing long-term unmanned research in the deep sea.

China's scientific research vessel Explorer 2, carrying the 4,500-meter manned submersible Shenhai Yongshi (Deep-sea Warrior), returned to Sanya in south China's Hainan Province recently, after completing its latest missions and the trial completion of a deep-sea in-situ scientific experiment station, media reported Monday.

More systems for intelligent unmanned experiments, detection and data delivery will be installed to the station in the future in order to realize long-term unmanned research in the deep sea, media reported Monday.

Following the research team’s return, the station and the devices installed in it will be powered by a domestic-developed one-megawatt-hour lithium energy system. It is the first time that the energy system has been installed at a depth of over 1,000 meters, demonstrating its safety and efficiency, media said.

One megawatt hour equals 1,000 kilowatts of electricity generated per hour, and is the maximum power capacity that deep-sea facilities can carry, Chen Jun from the CAS Institute of Deep-sea Science and Engineering was quoted as saying by media.

Five in-situ fluorescence sensors developed by CAS institutes were also used during the research in order to measure the concentration of chlorophyll, CDOM (colored soluble organic matter), tryptophan and other substances from the sea level to the whole profile of the seabed. The sensors can also work together with the in-situ experimental station to continuously monitor the concentration of target substances for long periods, supporting the exploration of deep-sea resources and environmental monitoring, media said citing related researchers.

During the latest research, researchers have also completed in-situ observation of the areas surrounding the Shenhai-1, China’s first self-run deep-sea gas field located 150 kilometers from Hainan Island, including its underwater mooring system and underwater production system, and obtained important data, according to the website of the CAS Institute of Deep-sea Science and Engineering.

Meanwhile, the researchers conducted functional tests on self-developed scientific research devices carried by Shenhai Yongshi, including a sampler for deep-sea sediment and deep-sea three-dimensional sensing equipment, the institute said.

Nature-inspired self-organizing collision avoidance for drone swarm based on reward-modulated spiking neural network​

Highlights​

  • Individuals learn from local observations to exhibit decentralized swarm behavior
  • We use reward-modulated spiking neural network for online collision avoidance learning
  • Multi-drone swarm achieves self-organized, stable, and safe flight in bounded space
  • Our method exhibits superior performance and stability to ANN-based methods

Summary​

Biological systems can exhibit intelligent swarm behavior through relatively independent individual, local interaction and decentralized decision-making. A major research challenge of self-organized swarm intelligence is the coupling influences between individual behaviors. Existing methods optimize the behavior of multiple individuals simultaneously from a global perspective. However, these methods lack in-depth inspiration from swarm behaviors in nature, so they are short of flexibly adapting to real multi-robot online decision-making tasks. To overcome such limits, this paper proposes a self-organized collision avoidance model for real drones incorporating a bio-inspired reward-modulated spiking neural network (RSNN). The local interaction and autonomous learning of a single individual leads to the emergence of swarm intelligence. We validated the proposed model on swarm collision avoidance tasks (a swarm of unmanned aerial vehicles without central control) in a bounded space, carrying out simulation and real-world experiments. Compared with artificial neural network-based online learning methods, our proposed method exhibits superior performance and better stability.

Underwater robot competition raises tech limits​


By ZHANG XIAOMIN in Dalian, Liaoning | CHINA DAILY | Updated: 2022-10-31 09:10

More breakthroughs are expected to be made at an underwater intelligent robot competition, which started on Friday in the coastal waters of Dalian Jinshitan National Tourist Resort, Liaoning province.

"If it hits a lateral current, the vehicle can automatically raise the speed of its propeller on the opposite side to maintain balance," said Liu Yuhang, a member of the OurEDA team from Dalian University of Technology.

The team ranked first in the man-machine coordination group in the last competition.

This year, the team has improved the software and hardware of their remotely operated vehicle to perform better with underwater image detection and image enhancement.

"We also added auxiliary functions like depth determination and orientation, so that the robot can hover at any depth," said Liu.

Initiated in 2017, the China Underwater Robot Professional Contest is comprised of one online competition and two offline competitions in the city of Dalian, as well as in Zhanjiang in Guangdong province.

The Dalian competition is sponsored by the National Natural Science Foundation of China, the city government of Dalian and Pengcheng Laboratory. This year, it attracted 20 teams with 110 members from domestic universities.

"It is the world's sole underwater intelligent robot competition held in a real offshore environment," said Luo Zhongxuan, vice-president of Dalian University of Technology, an organizer of the competition.

In recent years, the teams have been making progress in the areas of external design, intelligent algorithms integration and smart grasping. The record for intelligent underwater grasping operations has been constantly increasing, according to Luo.

Underwater robots are widely and urgently needed in areas such as sea ranching, subsea pipeline inspection and specialty operations.

Luo said the contest has become an exchange platform for supply and demand.

Dalian University of Technology is working closely with Pengcheng Laboratory on artificial intelligence and image processing, underwater robot bodies and underwater observation systems.

The two are also working with Jinpu New Area in Dalian to build an evaluation and test base for marine intelligent equipment in a bid to boost its research and development.

"We're focusing more on the influence of the contest as well as the transformation and application of its results," said Li Pengyu, deputy Party chief of Dalian and director of the administrative committee in the Dalian Jinpu New Area, the first State-level new area in Northeast China.

According to Li, Jinpu will build a platform to promote key projects in the sector.

"Some technologies and achievements of underwater robots are ready for industrial incubation," said Yuan Chi, head of the coastal city's science and technology bureau.

The base in Jinpu will play an important role in the evaluation of hardware and software of underwater vehicles and their industrial implementation, said Yuan.

"We hope to cultivate an underwater counterpart of civilian drone maker DJI Technology," he said.

This one just shows the scale and amount of money and R&D that can be accomplished through these large data centers.

And finally Huawei just signed up a new client to build their green energy data center

Yan Ning, a 45 year old Chinese structural biologist, announced that she would resign from Princeton University and return to China to join the Shenzhen Academy of Medical Sciences..

another huge win for China ..

The hits keep coming. At this rate, I wonder if US gov't will just stop allowing Chinese nationals from doing post grad research in American universities or even stopping Chinese grad students from doing PhD in America.

Domestically, China has to open up the society a little more so that these talents are willing to come back. Maybe open up more HK offices for those that don't want to live in Shenzhen or Shanghai.

How would you suggest doing this? Do you mean relax COVID zero? Or recreational marijuana, or offer dual passports, allow more non-ethnic Chinese immigration, legalize prostitution and gambling or something?

I knew this guy who organized an overseas conference for Nobel Physics laureates, and he told me the laureates actually wanted to visit brothels during their free time. No kidding. Lol. I still can't believe it. I'm sure a lot of top scientists use recreational drugs.
