| 1 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |
| 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 |

| 5 | Effects of annealing temperature on electrochemical performance of SnSx embedded in hierarchical porous carbon with N-carbon coating by in-situ structural phase transformation as anodes for lithium ion batteries显示文摘Tuned tin chalcogenides rooted in hierarchical porous carbon(HPC)with N-carbon coating layers are prepared by thermal shock under various temperatures(denoted as HPC-SnS_(2)-PAN-Various T).With the increase of annealing temperature,the morphology and phase structure of Sn S_(2),as well as the cyclization degree of polyacrylonitrile(PAN),are significantly changed,which leads to the formation of rod-like Sn S and ordered structure of conductive N-carbon layer.By combining HPC,N-carbon coating derived from the cyclization of PAN,with 1D Sn S nanorods generated from structural phase transformation of SnS_(2),the optimized composite(HPC-SnS_(2)-PAN-500)as anode for lithium ion batteries(LIBs)provides buffer space for volume changes during alloying/dealloying process,builds a highly conductive network as well as decreases irreversible capacity from solid electrolyte interphase and enhances the ion/electron transport.Attributed to the above merits from composition regulation and architecture modification by sulfur depletion and PAN cyclization,this target anode exhibits an extraordinary cycling stability with a high specific capacity of 652.5 m A h/g at 0.5 A/g after 900 cycles.It suggests that rod-like Sn S embedded in HPC with cyclized PAN layers by thermal treatment approach renders a potential structural design of anode materials for LIBs. | Qianqian Hu Biao Wang Shiyong Chang Chun Yang Yunjian Hu Shubin Cao Jiqun Lu Lingzhi Zhang Ye Hong | 2021 | Journal of Materials Science & Technology2021，，25： | 0 |
| 6 | A Pregnant Woman Died of Sudden Cardiac Death:Should Esophageal Foreign Body Be Considered an Inductive Factor?A Case Report and Literature Review显示文摘Here,we report a case of acute attack of coronary heart disease(CHD).A 47‑year‑old pregnant woman with gestational hypertension developed sudden‑onset chest tightness,palpitations,dyspnea,and cyanosis of the face and lips after admission.Her blood pressure was 180/110 mmHg and her blood oxygen saturation was 45%at that time.After cardiopulmonary resuscitation,a weak heartbeat was restored,but oxygen saturation did not increase significantly.Therefore,she was transferred to the intensive care unit;however,she died after 21 days of admission.Autopsy findings revealed that a foreign body was embedded in the esophagus near the right piriform,and her heart weighed 392 g;histopathological examination revealed CHD,thrombosis in the lumen of the right coronary artery,cardiomyocyte hypertrophy,vascular hyaline degeneration in arterioles,neutrophils in the bronchiole and alveolar.All the tested samples yielded negative toxicological results.Clinical status and autopsy findings were not compatible with a diagnosis of peripartum cardiomyopathy.The patient’s sudden death was attributed to CHD,and esophageal foreign‑body impaction was considered to be concomitant phenomenon.Our findings might help in increasing the awareness between esophageal foreign‑body impaction and sudden cardiac death and they can also help in clarifying that understanding the primary cause of death is the key to resolving an iatrogenic medical tangle. | Chang Cao Mingming Li Zhanzhan Liu Shiyong Fang Gang Chen Guang Chen Tongjun Ma Xuyang Zhu Xiang Xu | 2022 | Journal of Forensic Science and Medicine2022，8，4： | 0 |
| 7 | Early Cretaceous transpressional and transtensional tectonics straddling the Sulu orogenic belt,East China显示文摘The Sulu orogenic belt(SOB)separates the North and South China blocks in East Asia and formed during Triassic continent-continent collision.However,late Mesozoic post-collisional exhumation is poorly understood due to lack of surface evidence for Paleo-Pacific subduction and associated effects.This paper interprets the tectonic history of the SOB using detrital zircon age data from Early Cretaceous sedimentary units along with previously published geochronologic and geochemical data to reconstruct sedimentological and tectonic history.Detrital zircon age distributions obtained from sedimentary units include a 2.0 Ga subpopulation that appears only in turbidite units to the southeast.This sediment probably derived from the Yangtze Block.Terrestrial facies from the Jiao-Lai basin to the northwest appear to derive from the North China Block.Geochronologic and geochemical data indicate that Early Cretaceous,post-collisional volcanism was compositionally bimodal(mafic-felsic)with associated intrusive activity that peaked at 120 Ma.Seismic images of northerly regions of the study area indicate this occurred in an extensional setting.Sedimentary facies and field structural analyses revealed an unconformity interpreted to reflect rapid uplift with NW SE compression to the south.Given observed sinistral movement along the Tan-Lu fault,we interpret northwest and southeast regions of the SOB as experiencing transtensional and transpressional tectonics,respectively,driven by continuous subduction of the Paleo-Pacific Plate.Intrusion of the Late Yanshannian granitoids marked the final formational stage of this unique tectonic setting. | Jun Wang Su-Chin Chang Yong Chen Shiyong Yan | 2019 | Geoscience Frontiers2019，10，6： | 0 |
| 8 | Performances of a prototype point-contact germanium detector immersed in liquid nitrogen for light dark matter search显示文摘The CDEX-10 experiment searches for light weakly interacting massive particles, a form of dark matter, at the China Jinping Underground Laboratory, where approximately 10 kg of germanium detectors are arranged in an array and immersed in liquid nitrogen. Herein, we report on the experimental apparatus, detector characterization, and spectrum analysis of one prototype detector. Owing to the higher rise-time resolution of the CDEX-10 prototype detector as compared with CDEX-1 B, we identified the origin of an observed category of extremely fast events. For data analysis of the CDEX-10 prototype detector, we introduced and applied an improved bulk/surface event discrimination method. The results of the new method were compared to those of the CDEX-1 B spectrum. Both sets of results showed good consistency in the 0-12 ke Vee energy range, except for the 8.0 keV K-shell X-ray peak from the external copper. | Hao Jiang LiTao Yang Qian Yue KeJun Kang JianPing Cheng YuanJing Li Henry Tsz-King Wong M.A?artio?lu HaiPeng An JianPing Chang JingHan Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He Jin Wei Hu QingDong Hu HanXiong Huang LiPing Jia HauBin Li Hong Li Jian Min Li Jin Li Xia Li XueQian Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu YuanYuan Liu ZhongZhi Liu Hao Ma JingLu Ma Hui Pan Jie Ren XiChao Ruan B.Sevda Vivek Sharma ManBin Shen Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang JiMin Wang Li Wang Qing Wang Yi Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue SongWei Yang Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue XiongHui Zeng Ming Zeng Zhi Zeng FengShou Zhang YunHua Zhang MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu ZhongHua Zhu | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，3： | 0 |
