| 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 |
| 3 | Advanced surface engineering of titanium materials for biomedical applications:From static modification to dynamic responsive regulation显示文摘Titanium(Ti)and its alloys have been widely used as orthopedic implants,because of their favorable mechanical properties,corrosion resistance and biocompatibility.Despite their significant success in various clinical applications,the probability of failure,degradation and revision is undesirably high,especially for the patients with low bone density,insufficient quantity of bone or osteoporosis,which renders the studies on surface modification of Ti still active to further improve clinical results.It is discerned that surface physicochemical properties directly influence and even control the dynamic interaction that subsequently determines the success or rejection of orthopedic implants.Therefore,it is crucial to endow bulk materials with specific surface properties of high bioactivity that can be performed by surface modification to realize the osseointegration.This article first reviews surface characteristics of Ti materials and various conventional surface modification techniques involving mechanical,physical and chemical treatments based on the formation mechanism of the modified coatings.Such conventional methods are able to improve bioactivity of Ti implants,but the surfaces with static state cannot respond to the dynamic biological cascades from the living cells and tissues.Hence,beyond traditional static design,dynamic responsive avenues are then emerging.The dynamic stimuli sources for surface functionalization can originate from environmental triggers or physiological triggers.In short,this review surveys recent developments in the surface engineering of Ti materials,with a specific emphasis on advances in static to dynamic functionality,which provides perspectives for improving bioactivity and biocompatibility of Ti implants. | Pinliang Jiang Yanmei Zhang Ren Hu Bin Shi Lihai Zhang Qiaoling Huang Yun Yang Peifu Tang Changjian Lin | 2023 | Bioactive Materials2023，，9： | 2 |
| 4 | Effect of Longitudinal Momentum Spread in Ion-Ripple Laser显示文摘Using kinetic coupling mode theory of three waves,the effect of longitudinal momentum spread in ion-ripple laser(IRL),which is an advanced new scheme to generate tunable-coherent radiation with frequency ranging from microwaves to x-rays,is investigated.For a Gaussian distribution in beam longitudinal momentum,the results show that the growth rate of IRL falls off rapidly with increasing momentum spread,and the momentum spread causes linear damping of beam space-charge wave,weakening the beam-radiation mode coupling and lowering the output radiation frequency apart from broadening the radiation spectrum.The dispersion relation and phase matching conditions are also obtained. | LIU Pukun QIAN Shangjie TANG Changjian LIU Shenggang | 1994 | Chinese Physics Letters1994，11，3： | 0 |

| 6 | Comparison of Time Interval Statistic and Pulse Shape Discrimination in Fast Neutron Detection Method with Liquid Scintillation Detector Loaded Gd显示文摘Neutron usually appears with gamma,which is requiring the detector has the capability of n gamma discrimination.Pulse shape discrimination(PSD)is a common approach of n,gamma judgment,but required a complex process to select a suitable discrimination factor,and poor performance in the low energy range.A method based on the time interval of adjacent Signals was disrupted and adopted to compare to pulse shape discrimination in the fast neutron detection method.A good agreement between the adopted method and PSD method was achieved,including the total count ratio and neutron count ratio.The comparison proves the correctness of the theoretical derivation and validates the method in practice.The advantages and limitations of the method based on time Interval of adjacent signals were analyzed.The method provides an effective way to confirm the calibration of the neutron detection of a liquid scintillation detector.Also,as a simple way only requiring the time information about events,the described method has large application potential in some case of fast neutron flux or intensity measurement. | Mohammed Adel Al-jumaili Qiang Du Jingjun Zhu Xinde Lin Wenbin Lin Changjian Tang Mustafa Raad Kadhim Haoyang Xing Shukui Liu | 2017 | 应用物理前沿(中英文版)2017，5，1： | 0 |

| 8 | Influence of Poloidal Rotation of Plasma on Peeling-Ballooning Modes显示文摘Influence of the poloidal rotation of the plasma on Peeling-Ballooning modes(P-B modes)is studied with BOUT++code.The results show that the poloidal rotation destabilizes P-B modes because of the effect of Kelvin-Helmholtz instability when the poloidal rotation is large enough and the shear is small,and the shear of the poloidal rotation can stabilize high-n P-B modes when the shear is increased. | Yiyu Xiong Shaoyong Chen Changjian Tang Jie Huang Yang Luo | 2016 | 应用物理前沿(中英文版)2016，4，1： | 0 |
| 9 | 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 |
| 10 | Extraordinary toughening enhancement in nonstoichiometric vanadium carbide显示文摘1.Introduction Fracture toughness is the ability of materials against both the initiation and propagation of cracks[1],which is a crucial mechanical property for safety-critical applications of structural materials.Although the yield strength of ceramics is significantly higher than that of metallic materials,the fracture toughness is severely lower than that of metallic materials due to the strongly directional covalent bonding[1-3].For a long time,how to improve the fracture toughness of ceramics without the deterioration of strength(or hardness)has been one of the most challenging problems in materials science. | Chong Peng Hu Tang Changjian Geng Pengjie Liang Biao Wan Yujiao Ke Yuefeng Wang Peng Jia Wenfeng Peng Lina Qiao Kenan Li Xiaohong Yuan Yucheng Zhao Mingzhi Wang | 2022 | Journal of Materials Science & Technology2022，，2： | 0 |
| 11 | Deciphering controversial results of cell proliferation on TiO2 nanotubes using machine learning显示文摘With the rapid development of biomedical sciences,contradictory results on the relationships between biological responses and material properties emerge continuously,adding to the challenge of interpreting the incomprehensible interfacial process.In the present paper,we use cell proliferation on titanium dioxide nanotubes(TNTs)as a case study and apply machine learning methodologies to decipher contradictory results in the literature.The gradient boosting decision tree model demonstrates that cell density has a higher impact on cell proliferation than other obtainable experimental features in most publications.Together with the variation of other essential features,the controversy of cell proliferation trends on various TNTs is understandable.By traversing all combinational experimental features and the corresponding forecast using an exhausted grid search strategy,we find that adjusting cell density and sterilization methods can simultaneously induce opposite cell proliferation trends on various TNTs diameter,which is further validated by experiments.This case study reveals that machine learning is a burgeoning tool in deciphering controversial results in biomedical researches,opening up an avenue to explore the structure-property relationships of biomaterials. | Ziao Shen Si Wang Zhenyu Shen Yufei Tang Junbin Xu Changjian Lin Xun Chen Qiaoling Huang | 2021 | Regenerative Biomaterials2021，8，4： | 0 |
