| 1 | Small molecular non-fullerene electron acceptors for P3HT-based bulk-heterojunction solar cells显示文摘Three small molecules with the same arms and different cores of perylene diimide(PDI)or indaceno[2,1-b:6,5-b']dithiophene(IDT)were designed and synthesized as the acceptor materials for P3HT-based bulk-heterojunction(BHJ)solar cells.The impacts of the different cores on the optical absorption,electrochemical properties,electron mobility,film morphology,photoluminescene characteristics,and solar cell performance were thoroughly studied.The three compounds possess a broad absorption covering the wavelength range of 400–700 nm and relatively low lowest unoccupied molecular orbital(LUMO)energy levels of?3.86,?3.81 and?3.99 eV.The highest power conversion efficiency of 0.82%was achieved for the BHJ solar cells based on SM3 as the acceptor material,the compound with a PDI core. | LIU Xin CAI Ping CHEN DongChen CHEN JunWu SU ShiJian CAO Yong | 2014 | Science China Chemistry2014，57，7： | 5 |
| 2 | Protecting healthcare personnel from 2019-nCoV infection risks:lessons and suggestions显示文摘The outbreak of a novel coronavirus disease(COVID-19,caused by the 2019-nCoV infection)in December 2019 is one of the most severe public health emergencies since the founding of People’s Republic of China in 1949.Healthcare personnel(HCP)nationwide are facing heavy workloads and high risk of infection,especially those who care for patients in Hubei Province.Sadly,as of February 20,2020,over two thousand COVID-19 cases are confirmed among HCP from 476 hospitals nationwide,with nearly 90%of them from Hubei Province.Based on literature search and interviews with some HCP working at Wuhan,capital city of Hubei,we have summarized some of the effective measures taken to reduce infection among HCP,and also made suggestions for improving occupational safety during an infectious disease outbreak.The experience and lessons learned should be a valuable asset for international health community to contain the ongoing COVID-19 epidemic around the world. | Zhiruo Zhang Shelan Liu Mi Xiang Shijian Li Dahai Zhao Chaolin Huang Saijuan Chen | 2020 | Frontiers of Medicine2020，14，2： | 4 |
| 3 | A Monte Carlo Neural Fictitious Self-Play approach to approximate Nash Equilibrium in imperfect-information dynamic games显示文摘Solving the optimization problem to approach a Nash Equilibrium point plays an important role in imperfect information games,e.g.,StarCraft and poker.Neural Fictitious Self-Play(NFSP)is an effective algorithm that learns approximate Nash Equilibrium of imperfect-information games from purely self-play without prior domain knowledge.However,it needs to train a neural network in an off-policy manner to approximate the action values.For games with large search spaces,the training may suffer from unnecessary exploration and sometimes fails to converge.In this paper,we propose a new Neural Fictitious Self-Play algorithm that combines Monte Carlo tree search with NFSP,called MC-NFSP,to improve the performance in real-time zero-sum imperfect-information games.With experiments and empirical analysis,we demonstrate that the proposed MC-NFSP algorithm can approximate Nash Equilibrium in games with large-scale search depth while the NFSP can not.Furthermore,we develop an Asynchronous Neural Fictitious Self-Play framework(ANFSP).It uses asynchronous and parallel architecture to collect game experience and improve both the training efficiency and policy quality.The experiments with th e games with hidden state information(Texas Hold^m),and the FPS(firstperson shooter)games demonstrate effectiveness of our algorithms. | Li ZHANG Yuxuan CHEN Wei WANG Ziliang HAN Shijian Li Zhijie PAN Gang PAN | 2021 | Frontiers of Computer Science2021，15，5： | 3 |
| 4 | Review on observational studies of western tropical Pacific Ocean circulation and climate显示文摘The Western Tropical Pacific(WTP) Ocean holds the largest area of warm water(>28℃) in the world ocean referred to as the Western Pacific Warm Pool(WPWP),which modulates the regional and global climate through strong atmospheric convection and its variability.The WTP is unique in terms of its complex 3-D ocean circulation system and intensive multiscale variability,making it crucial in the water and energy cycle of the global ocean.Great advances have been made in understanding the complexity of the WTP ocean circulation and associated climate impact by the international scientific community since the 1960 s through field experiments.In this study,we review the evolving insight to the 3-D structure and multi-scale variability of the ocean circulation in the WTP and their climatic impacts based on in-situ ocean observations in the past decades,with emphasis on the achievements since 2000.The challenges and open que stions remaining are reviewed as well as future plan for international study of the WTP ocean circulation and climate. | HU Dunxin WANG Fan SPRINTALL Janet WU Lixin RISER Stephen CRAVATTE Sophie GORDON Arnold ZHANG Linlin CHEN Dake ZHOU Hui ANDO Kentaro WANG Jianing LEE Jae-Hak HU Shijian WANG Jing ZHANG Dongxiao FENG Junqiao LIU Lingling VILLANOY Cesar KALUWIN Chalapan QU Tangdong MA Yixin | 2020 | Journal of Oceanology and Limnology2020，38，4： | 3 |

| 6 | Experimental investigation of Z-pinch radiation source for indirect drive inertial confinement fusion显示文摘Z-pinch dynamic hohlraums(ZPDHs)could potentially be used to drive inertial confinement fusion targets.Double-or multishell capsules using the technique of volume ignition could exploit the advantages of ZPDHs while tolerating their radiation asymmetry,which would be unacceptable for a central ignition target.In this paper,we review research on Z-pinch implosions and ZPDHs for indirect drive targets at the Institute of Nuclear Physics and Chemistry,China Academy of Engineering Physics.The characteristics of double-shell targets and the associated technical requirements are analyzed through a one-dimensional computer code developed from MULTI-IFE.Some key issues regarding the establishment of suitable sources for dynamic hohlraums are introduced,such as soft X-ray power optimization,novel methods for plasma profile modulation,and the use of thin-shell liner implosions to inhibit the generation of prior-stagnated plasma.Finally,shock propagation and radiation characteristics in a ZPDH are presented and discussed,together with some plans for future work. | Zhenghong Li Zhen Wang Rongkun Xu Jianlun Yang Fan Ye Yanyun Chu Zeping Xu Faxin Chen Shijian Meng Jianmin Qi Qinyuan Hu Yi Qin Jiaming Ning Zhanchang Huang Linbo Li Shuqing Jiang | 2019 | Matter and Radiation at Extremes2019，4，4： | 1 |

| 8 | SARS-CoV-2 Omicron strain exhibits potent capabilities for immune evasion and viral entrance显示文摘Dear Editor,Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron strain(as Rnown as B.1.1.529)was identified in Botswana and South Africa in early November 2021 and was later defined as a new variant of concern(VOC)by the World Health Organization on November 26,2021.1,2 To date,the con firmed cases of Omicro n have been reported in more than 38 countries,and the number of cases appears to be rapidly in creasing.SARS-CoV-2 Omicron could give rise to the fourth wave of the COVID-19 epidemic spreading around the world,following the D614G,Beta/Gamma,and Delta VOCs. | Xiantao Zhang Shijian Wu Bolin Wu Qirui Yang Achun Chen Yuzhuang Li Yiwen Zhang Ting Pan Hui Zhang Xin He | 2022 | Signal Transduction and Targeted Therapy2022，7，1： | 1 |
