The new technology is based on an improved method to detect motion blur. A parameterized motion blur kernel is mapped into the 3D pose space of the camera to obtain a 3D pose set, and the intersection of the 3D pose sets (shared pose set) corresponding to multiple image patches is obtained. Compared with state-of-the-art methods, the detection accuracy of the proposed method is claimed to be improved by more than 20%.

On an area of ​​5,000 mu (approximately 333.3 hectares) with an average altitude of more than 2,200 meters at Wei Ning Yi Hui Miao Autonomous County, engineers seek lead technologies for vegetable production such as Chinese or white cabbage and radish. 5G-supported drones with multispectral equipment monitor crop growth, soil moisture and weather conditions and make decisions using an AI judgment system. Remote operation maintenance and quality tracing will be installed in Guiyang city. If the “smart farm” trial is successful, 400,000-mu (approximately 26,700 hectares) vegetable bases will also be built in all prefectures.

GAO Hongjun and colleagues from CAS Institute of Physics have achieved atomically precise folding of graphene nanostructures through STM tip-induced manipulation technology. They were able to fold graphene nanoislands in an arbitrarily chosen direction, constructed bilayer graphene stacks withs a tunable twist angle and a tubular edge connection between the layers, and created intramolecular junctions of bicrystal graphene nanoislands. Atomically precise “origami” can be used for the construction of quantum materials and quantum devices.

The project initiated by LI Can of CAS Dalian Institute of Chemical Physics combines hydrogen production by electrocatalytic water splitting with highly selective, carbon dioxide hydrogenation to methanol. Energy consumption is reduced to 4.0-4.2 kWh / m3 hydrogen. Carbon dioxide hydrogenation to methanol uses a bimetal oxide catalyst (ZnO-ZrO2). Methanol selectivity is greater than 90%, and degradation of the catalyst after 3000 hours of operation is less than 2%. A1,000-ton scale demonstration project was commissioned in the Green Chemical Park in Lanzhou New District.

China’s quantum satellite QUESS (Quantum Experiments at Space Scale, nickname Micius), jointly developed by the University of Science and Technology of China, QuantumCTek Co., Ltd. and the Jinan Institute of Quantum Technology, was successfully linked up with a mobile quantum ground station and conducted an encrypted data transmission in Jinan, Shandong Province. The latest mobile version installed on a vehicle has been significantly reduced in weight and construction cost. The experimental quantum communication network in Jinan was further connected to the Beijing-Shanghai quantum communication backbone network.

The incidence of osteoarthritis among Chinese is about 2.2 to 3.5 percent, with an upward trend. The First Hospital affiliated to Army Medical University (AMU)  so far has conducted 27 clinical trials on knee implants based on customized 3D-printed porous tantalum. After 3D CT scan of a patient’s bone and bone defects, it takes only 72 hours to design a porous tantalum implant and 3D print the customized implant.

The solar sail is a spacecraft powered by the reflected light pressure of the sun on the film. It does not consume additional chemical fuel during the voyage. Features are a small mass, low cost, low power consumption, and long range. “Tianfan-1″ is a solar sail developed by the CAS Shenyang Institute of Automation and was launched by a Xiaoxiang-1 satellite 07 on August 31. “Tianfan-1” has recently carried out a series of key technical tests on unfolding and assembling and will provide technology for solar sail research and development at a larger scale.
