| 2 | First results on ^(76)Ge neutrinoless double beta decay from CDEX-1 experiment显示文摘We report the first results on ^(76)Ge neutrinoless double beta decay from stage one of the China dark-matter experiment(CDEX).A p-type point-contact high-purity germanium detector with a mass of 994 g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304 kg d has been analyzed over a wide spectral band from 500 keV to 3 MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039 MeV energy range. The half-life of ^(76)Ge neutrinoless double beta decay derived based on this result is T^(0ν)1/2>6.4×10^(22) yr(90% C.L.). An upper limit on the effective Majorana-neutrino mass of 5.0 eV has been achieved. | Li Wang Qian Yue KeJun Kang JianPing Cheng YuanJing Li TszKing Henry Wong ShinTed Lin JianPing Chang JingHan Chen QingHao Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He QingJu He JinWei Hu HanXiong Huang TengRui Huang LiPing Jia Hao Jiang HauBin Li Hong Li JianMin Li Jin Li Jun Li Xia Li XueQian Li YuLan Li FongKay Lin ShuKui Liu Hao Ma JingLu Ma XingYu Pan Jie Ren XiChao Ruan ManBin Shen Vivek Sharma Lakhwinder Singh Manoj Kumar Singh Manoj Kumar Singh Arun Kumar Soma ChangJian Tang WeiYou Tang ChaoHsiung Tseng JiMin Wang Qing Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue LiTao Yang SongWei Yang Nan Yi ChunXu Yu HaiJun Yu WeiHe Zeng XiongHui Zeng Zhi Zeng Lan Zhang YunHua Zhang MingGang Zhao Wei Zhao JiFang Zhou ZuYing Zhou JingJun Zhu WeiBin Zhu ZhongHua Zhu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，7： | 3 |
| 3 | Boosting reversible anionic redox reaction with Li/Cu dual honeycomb centers显示文摘The anionic redox reaction(ARR)is a promising charge contributor to improve the reversible capacity of layeredoxide cathodes for Na-ion batteries;however,some practical bottlenecks still need to be eliminated,including a low capacity retention,large voltage hysteresis,and low rate capability.Herein,we proposed a high-Na content honeycomb-ordered cathode,P2–Na_(5/6)[Li_(1/6)Cu_(1/6)Mn_(2/3)]O_(2)(P2-NLCMO),with combined cationic/anionic redox.Neutron powder diffraction and X-ray diffraction of P2-NLCMO suggested P2-type stacking with rarely found P6322 symmetry.In addition,advanced spectroscopy techniques and density functional theory calculations confirmed the synergistic stabilizing relationship between the Li/Cu dual honeycomb centers,achieving fully active Cu^(3+)/Cu^(2+) redox and stabilized ARR with interactively suppressed local distortion.With a meticulously regulated charge/discharge protocol,both the cycling and rate capability of P2-NLCMO were significantly. | Xiaohui Rong Dongdong Xiao Qinghao Li Yaoshen Niu Feixiang Ding Xueyan Hou Qiyu Wang Juping Xu Chenglong Zhao Dong Zhou Ruijuan Xiao Xiqian Yu Wen Yin Lin Gu Hong Li Xuejie Huang Liquan Chen Yong-Sheng Hu | 2023 | eScience2023，3，5： | 0 |

| 5 | In situ magnetometry study on the origin of anomalously capacity in transition metal sulfides显示文摘Cobalt sulfides are considered as promising candidates for lithium-ion battery(LIB)anode materials with high energy densities.Their energy storage mechanism is widely understood to involve the traditional intercalation and conversion reaction.However,these conventional mechanisms are unable to explain the storage capacities of certain materials which exceed the theoretical limit.Here,utilizing advanced in situ magnetometry to detect the magnetization evolution of Co_(1-x) S LIBs in real time,it is demonstrated that the Co-catalytic lithium storage process and interfacial space charge storage mechanism are strongly related to the additional capacity of cobalt sulfides.During discharge,a Co/Li_(2) S interface is formed,wherein the Co nanoparticles and Li_(2) S could store a large amount of polarized electrons Li^(+),respectively.Subsequently,the electrons stored in Co are transferred to the polymeric film,forming radical anions and contributing extra capacity.These findings reveal the charge storage mechanisms of transition metal sulfides and highlight the critical role of magnetic testing in the investigation of energy storage mechanisms. | Yan Liu Yuanyuan Han Shuxuan Liao Fangchao Gu Hengjun Liu Xixiang Xu Zhiqiang Zhao Xiancheng Sang Qinghao Li Weijin Kong Qiang Li | 2023 | ChemPhysMater2023，2，3： | 0 |
| 6 | Synthesis, potential anticonvulsant and antidepressant effects of 2-(5-methyl-2,3-dioxoindolin-1-yl)acetamide derivatives显示文摘A new series of 2-(5-methyl-2,3-dioxoindolin-1-yl)acetamide derivatives were synthesized and evaluated for their anticonvulsive activity in a pentylenetetrazole(PTZ)-evoked convulsion model and antidepressant activity in the forced swimming test(FST) model. Eleven synthesized compounds were found to be protective against PTZ-induced seizure and showed the anticonvulsant activity. In addition,four of the synthesized compounds(4l, 4m, 4p and 4q) showed potent antidepressant-like activity.Among these compounds, compound 4l was found to have the most potent antidepressant-like activity,and significantly reduced the duration of immobility time at 100 mg/kg dose level when compared to the vehicle control, which is similar to the reference drug fluoxetine. | Xinghua Zhen Zhou Peng Shuilian Zhao Yan Han Qinghao Jin Liping Guan | 2015 | Acta Pharmaceutica Sinica B2015，5，4： | 0 |
| 7 | Identifying change patterns of API misuses from code changes显示文摘Library or framework APIs are difficult to learn and use,leading to unexpected software behaviors or bugs.Hence,various API mining techniques have been introduced to mine API usage patterns about the co-occurring of API calls or pre-conditions of API calls.However,they fail to mine patterns about an API call itself(e.g.,whether the arguments of the API call are correctly set and whether the API is suitably chosen over other similar APIs).To bridge this gap,we propose Cpam to identify change patterns(in the form of a pair of APIs before and after code changes)to fix API misuses,using historical code changes.Given a set of target APIs and a corpus of open-source projects,Cpam first selects the commits that potentially fix API misuses from the corpus,then extracts changes to API misuses in each selected commit,and finally identifies change patterns of API misuses.We implement Cpam for Java,and conduct large-scale evaluation,targeting Java SE APIs and using a corpus of 1162 Java projects.Our experimental results demonstrate Cpam’s effectiveness and efficiency.By applying identified change patterns to bug detection,we find 44 new bugs,and 18 of them have been confirmed and fixed. | Wenjian LIU Bihuan CHEN Xin PENG Qinghao SUN Wenyun ZHAO | 2021 | Science China(Information Sciences)2021，64，3： | 0 |
| 8 | A Broad Range Triboelectric Stiffness Sensor for Variable Inclusions Recognition显示文摘With the development of artificial intelligence,stiffness sensors are extensively utilized in various fields,and their integration with robots for automated palpation has gained significant attention.This study presents a broad range self-powered stiffness sensor based on the triboelectric nanogenerator(Stiff-TENG)for variable inclusions in soft objects detection.The Stiff-TENG employs a stacked structure comprising an indium tin oxide film,an elastic sponge,a fluorinated ethylene propylene film with a conductive ink electrode,and two acrylic pieces with a shielding layer.Through the decoupling method,the Stiff-TENG achieves stiffness detection of objects within 1.0 s.The output performance and characteristics of the TENG for different stiffness objects under 4 mm displacement are analyzed.The Stiff-TENG is successfully used to detect the heterogeneous stiffness structures,enabling effective recognition of variable inclusions in soft object,reaching a recognition accuracy of 99.7%.Furthermore,its adaptability makes it well-suited for the detection of pathological conditions within the human body,as pathological tissues often exhibit changes in the stiffness of internal organs.This research highlights the innovative applications of TENG and thereby showcases its immense potential in healthcare applications such as palpation which assesses pathological conditions based on organ stiffness. | Ziyi Zhao Zhentan Quan Huaze Tang Qinghao Xu Hongfa Zhao Zihan Wang Ziwu Song Shoujie Li Ishara Dharmasena Changsheng Wu Wenbo Ding | 2023 | Nano-Micro Letters2023，15，12： | 0 |
| 9 | Anatomical morphology of the aortic valve in Chinese aortic stenosis patients and clinical results after downsize strategy of transcatheter aortic valve replacement显示文摘Background:The study aimed to describe the aortic valve morphology in Chinese patients underwent transcatheter aortic valve replacement(TAVR)for symptomatic severe aortic stenosis(AS),and the impact of sizing strategies and related procedural outcomes.Methods:Patients with severe AS who underwent TAVR were consecutively enrolled from 2012 to 2019.The anatomy and morphology of the aortic root were assessed.'Downsize'strategy was preformed when patients had complex morphology.The clinical outcomes of patients who performed downsize strategy were compared with those received annular sizing strategy.The primary outcome was device success rate,and secondary outcomes included Valve Academic Research Consortium-3 clinical outcomes variables based on 1-year follow-up.Results:A total of 293 patients were enrolled.Among them,95 patients(32.4%)had bicuspid aortic valve.The calcium volume(Hounsfield Unit-850)of aortic root was 449.90(243.15-782.15)mm3.Calcium is distributed mostly on the leaflet level.Downsize strategy was performed in 204 patients(69.6%).Compared with the patients who performed annular sizing strategy,those received downsize strategy achieved a similar device success rate(82.0%[73]vs.83.3%[170],P=0.79).Aortic valve gradients(downsize strategy group vs.annular sizing group,11.28 mmHg vs.11.88 mmHg,P=0.64)and percentages of patients with moderate or severe paravalvular regurgitation 2.0%(4/204)vs.4.5%(4/89),P=0.21were similar in the two groups at 30 days after TAVR.These echocardiographic results were sustainable for one year.Conclusions:Chinese TAVR patients have more prevalent bicuspid morphology and large calcium volume of aortic root.Calcium is distributed mostly on the leaflet level.Compare with annular sizing strategy,downsize strategy provided a non-inferior device success rate and transcatheter heart valve hemodynamic performance in self-expanding TAVR procedure. | Guannan Niu Walid Ben Ali Moyang Wang Hasan Jilaihawi Haitong Zhang Qian Zhang Yunqing Ye Xinmin Liu Jing Yao Qinghao Zhao Yubin Wang Zheng Zhou Lizhi Zhang Xinshuang Ren Yunqiang An Bin Lu Thomas Modine Yongjian Wu Guangyuan Song | 2022 | Chinese Medical Journal2022，135，24： | 0 |
