| 1 | Sensors deployment optimization in multi-dimensional space based on improved particle swarm optimization algorithm显示文摘Sensors deployment optimization has become one of the most attractive fields in recent years. However, most of the previous work focused on the deployment problem in 2 D space.Compared to the traditional form, sensors deployment in multidimensional space has greater research significance and practical potential to satisfy the detecting needs in complex environment.Aiming at solving this issue, a multi-dimensional space sensor network model is established, and the radar system is selected as an example. Considering the possible working mode of the radar system(e.g., searching and tracking), two distinctive deployment models are proposed based on maximum coverage area and maximum target detection probability in the attack direction respectively. The latter one is usually ignored in the previous literature.For uncovering the optimal deployment of the sensor network, the particle swarm optimization(PSO) algorithm is improved using the proposed weights determination scheme, in which the linear decreasing, the pooling strategy and the cloud theory are combined for weights updating. Experimental results illustrate the effectiveness of the proposed method. | TANG Mingnan CHEN Shijun ZHENG Xuehe WANG Tianshu CAO Hui | 2018 | Journal of Systems Engineering and Electronics2018，29，5： | 6 |
| 2 | Review of Si IGBT and SiC MOSFET Based on Hybrid Switch显示文摘SiC Hybrid switch(HyS)combines low conduction loss of Si IGBT and low switching loss of SiC MOSFET,and the cost is closer to that of Si IGBT.The promising high performances of HyS will bring considerable achievement in terms of enhancing power density of a converter system.By reviewing the gate drive pattern,gate drive hardware,current sharing,module design,converter design,and cost,this paper introduces state-of-the-art SiC HyS. | Puqi Ning Tianshu Yuan Yuhui Kang Cao Han Lei Li | 2019 | Chinese Journal of Electrical Engineering2019，5，3： | 5 |
| 3 | Transient acquisition of cross-species infectivity during the evolution of SARS-CoV-2显示文摘Since the coronavirus disease 2019(COVID-19)pandemic began,its causative agent,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),has spread worldwide.During the global transmission of SARS-CoV-2,mutations in the viral genome have gradually accumulated and have led to the emergence of variants.These emerging variants;including 501Y.V1,501Y.V2 and 501Y.V3(also called the alpha,beta and gamma variants,respectively),rapidly became the predominant epidemic strains and subsequently spread worldwide. | Qi Chen Xing-Yao Huang Meng-Xu Sun Rui-Ting Li Hongjing Gu Ying Tian Rong-Rong Zhang Dan Luo Chao Zhou Yifei Zhang Tianshu Cao Na-Na Zhang Yong-Qiang Deng Xiao-Feng Li Cheng-Feng Qin | 2021 | National Science Review2021，8，11： | 3 |
| 4 | Genomic profiling and the impact of MUC19 mutation in hepatoid adenocarcinoma of the stomach显示文摘Dear Editor,Hepatoid adenocarcinoma(HAC)is a rare pathological subtype of extrahepatic tumor,featured by hepatoid differentiation andα-fetoprotein(AFP)-production[1,2].Hepatoid adenocarcinoma of the stomach(HAS),accounting for 0.3%to 1.0%of all gastric cancers(GCs),has attracted increasing attention due to its high degree of malignancy[3].Compared with classic GC,HAS showed a higher rate of vascular invasion,lymph node metastasis,and liver metastasis,with only 9.0%survival rate at 5 years[4].Currently,there is no effective treatment for HAS,and little is known about its pathogenesis.Herein,we investigated the molecular features of HAS and identified potential therapeutic targets for HAS. | Mengxuan Zhu Erbao Chen Shan Yu Chen Xu Yiyi Yu Xin Cao Wei Li Pengfei Zhang Yan Wang Baofeng Lian Shuirong Zhang Yueting Qu Lujia Huang Weiwei Shi Yuehong Cui Li Qian Tianshu Liu | 2022 | Cancer Communications2022，42，10： | 3 |

| 6 | China enters CAR-T cell therapy era显示文摘The emerging individualized and living-cell-based genetic engineering chimeric antigen receptor T(CAR-T)therapy demonstrates great curative effects in some hematological tumor treatments,thus it is turning out to be a star immunotherapy method of the world.1 Recently,the China NationalMedical Products Administration(NMPA)approved launching applications of two CAR-T cell cancer products,Axicabtagene Ciloleucel(FKC876)and Relmacabtagene Autoleucel(Carteyva),which marked the beginning of the of CAR-T cell therapy era in China(Figure 1). | Xin Cao Wei Li Yiyi Yu Tianshu Liu Yuhong Zhou | 2022 | The Innovation2022，3，1： | 0 |
| 7 | PLC for In-Vehicle Network:A DRL-Based Algorithm of Diversity Combination of OFDM Subcarriers显示文摘For low latency communication service of vehicles,it is critical to improve the delay performance of power line communication(PLC)for in-vehicle network,which can decrease the weight and cost of the vehicle.In order to minimize the total time slots used in a transmission task,an orthogonal frequency-division multiplexing(OFDM)subcarrier diversity combination algorithm of PLC based on the deep reinforcement learning(DRL)is proposed herein.The short packet communication theory is used to develop an optimal combination model with constraints on short packet reliability,transmitting power and the amount of data.The state,action,and reward function of double deep Q-learning network(DDQN)are defined,and diversity combination for OFDM subcarriers is performed using DDQN.An adaptive power allocation algorithm based on the thresholds of error rate and the data amount is used.Simulation results show that the proposed algorithm can effectively improve the delay performance of PLC under the constraints of power and data amount. | CHEN Zhixiong ZHANG Zhikun CAO Tianshu ZHOU Zhenyu | 2023 | Chinese Journal of Electronics2023，32，6： | 0 |
| 8 | Configuration and Setting of Protections for Wind Farm Collector System显示文摘Compared with traditional synchronous generators, wind turbine generators are different in electricity generation principles, control modes and integration topologies, which makes their fault characteristics change a lot. This, consequently, brings challenges regarding the behavior of protections for wind farm collector systems. In this paper, based on a practical wind farm, configuration and setting of relay protections for such a collector system is analyzed and determined systematically in consideration of the selectivity and sensitivity of the protections. Results show that misoperation of overcurrent relay and zero sequence overcurrent relay of the non-fault collector line occurs, and bus differential relay of collector bus cannot remove the single-phase-to-ground fault. In order to solve the problems, a novel substation-area protection for collector system is proposed and its operation mechanism is discussed. | Li Yanbin Zhang Li Bi Tianshu Cao Hong Liu Sumei | 2014 | Electricity2014，25，5： | 0 |
