Maintaining human thermal co.fort in co.d indoor environments is crucial but usually involves excessive energy co.sumption and massive greenhouse gas emissions. Thermoregulating the human body by using advanced clothing is emerging as a promising solution to effectively and energy-efficiently achieve personal thermal management. An air inflatable suit(AirST)using a series of air chambers as the thermal insert was developed for the purpose of adjusting clothing thermal insulation and hence improving personal thermal co.fort. The thermal insulation regulating performance of AirST was investigated through thermal manikin tests and wear trials. co.pared with the AirST without air inflation, AirST after inflation with air had a desired effect, which co.ld not only increase local clothing thermal insulation by a range from 4.5% to 24.8% but also alleviate co.d strain and provide significantly higher local skin temperatures, mean skin temperature and mean body temperature. After inflation, AirST successfully improved the whole-, upper-and lower-body thermal sensations in a co.l environment. The acceptable heating setpoint temperature by the air co.ditioner co.ld be decreased while using AirST with inflation, which saved approximately 30% of building energy co.sumption. As the AirST without air inflation can also be worn as regular windproof clothing, this versatility saved approximately 12 kg co.(2)e emissions in the production process.

Progress in bulk GaN growth

Chinese Physics B 2015年第6期24卷 1-16页

作者：徐科王建峰任国强 suzhou Institute of Nano-tech and Nano-bionics Chinese Academy of Sciences suzhou Nanowin Science and technology co. Ltd.

Three main technologies for bulk GaN growth, i.e., hydride vapor phase epitaxy （HVPE）, Na-flux method, and am- monothermal method, are discussed. We report our recent work in HVPE growth of GaN substrate, including dislocation reduction, strain co.trol, separation, and doping of GaN film. The growth mechanisms of GaN by Na-flux and ammonother- mal methods are co.pared with those of HVPE. The mechanical behaviors of dislocation in bulk GaN are investigated through nano-indentation and high-space resolution surface photo-voltage spectrosco.y. In the last part, the progress in growing some devices on GaN substrate by homo-epitaxy is introduced.

Optical experimental solution for the multiway number partitioning problem and its application to co.puting power scheduling

引用

Science China(Physics,Mechanics & Astronomy) 2023年第9期66卷 15-22页

作者： Jingwei Wen Zhenming Wang Zhiguo Huang Dunbo Cai Bingjie Jia Chongyu Cao Yin Ma Hai Wei Kai Wen Ling Qian China Mobile(suzhou)Software technology co.pany Limited Suzhou 215163China Beijing QBoson Quantum technology co. Ltd.Beijing 100015China

Quantum co.puting is an emerging technology that is expected to realize an exponential increase in co.puting power. Recently,its theoretical foundation and application scenarios have been extensively researched and explored. In this work, we propose efficient quantum algorithms suitable for solving co.puting power scheduling problems in the cloud-rendering domain, which can be viewed mathematically as a generalized form of a typical NP-co.plete problem, i.e., a multiway number partitioning *** our algorithm, the matching pattern between tasks and co.puting resources with the shortest co.pletion time or optimal load balancing is enco.ed into the ground state of the Hamiltonian;it is then solved using the optical co.erent Ising machine, a practical quantum co.puting device with at least 100 qubits. The experimental results show that the proposed quantum scheme can achieve significant acceleration and save 97% of the time required to solve co.binatorial optimization problems co.pared with classical algorithms. This demonstrates the co.putational advantages of optical quantum devices in solving co.binatorial optimization problems. Our algorithmic and experimental work will advance the utilization of quantum co.puters to solve specific NP problems and will broaden the range of possible applications.
