1Efficient and stable planar all-inorganic perovskite solar cells based on high-quality CsPbBr3 films with controllable morphology显示文摘All-inorganic cesium lead bromide(CsPbBr3)perovskite is attracting growing interest as functional materials in photovoltaics and other optoelectronic devices due to its superb stability.However,the fabrication of high-quality CsPbBr3 films still remains a big challenge by solution-process because of the low solubility of the cesium precursor in common solvents.Herein,we report a facile solution-processed approach to prepare high-quality CsPbBr3 perovskite films via a two-step spin-coating method,in which the Cs Br methanol/H2 O mixed solvent solution is spin-coated onto the lead bromide films,followed by an isopropanol-assisted post-treatment to regulate the crystallization process and to control the film morphology.In this fashion,dense and uniform CsPbBr3 films are obtained consisting of large crystalline domains with sizes up to microns and low defect density.The effectiveness of the resulting CsPbBr3 films is further examined in perovskite solar cells(PSCs)with a simplified planar architecture of fluorine–doped tin oxide/compact Ti O2/CsPbBr3/carbon,which deliver a maximum power conversion efficiency of 8.11%together with excellent thermal and humidity stability.The present work offers a simple and effective strategy in fabrication of high-quality CsPbBr3 films for efficient and stable PSCs as well as other optoelectronic devices.Xiaojing Wan Ze Yu Wenming Tian Fuzhi Huang Shengye Jin Xichuan Yang Yi-Bing Cheng Anders Hagfeldt Licheng Sun 2020Journal of Energy Chemistry2020,29,7:6
2Magnetostratigraphy of a Loess-Paleosol Sequence from Higher Terrace of the Daduhe River in the Eastern Margin of the Tibetan Plateau and Its Geological Significance显示文摘The eolian deposits distributed in the river valleys in the eastern margin of the Tibetan Plateau(TP)are very useful in neotectonic and paleoclimatic studies.Firstly,the climate in the eastern margin of the TP is mainly controlled by the Indian summer monsoon,and detailed studies on the loess-paleosol sequences in this region can provide valuable terrestrial evidence of past changes in the Indian summer monsoon.Secondly,the river terraces in the eastern margin of the TP are considered to be a sensitive recorder of neotectonism to reflect the timing and amplitude of the TP uplift.The formation ages ofQIAO Yansong WANG Yan YAO Haitao QI Lin HE Ze Xin CHENG Yu PENG Shasha GE Junyi 2015Acta Geologica Sinica(English Edition)2015,89,1:5

4Translation and validation of the Tibetan confusion assessment method for the intensive care unit显示文摘Background: At present, there is no available delirium translated assessment method for 3.3 million Tibetans. This study ai provide a method for delirium assessment for Tibetan patients speaking this language by validating a translation of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Methods: The study was conducted between July 2018 and November 2018. Patients were screened for delirium by a neurologist using the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV). Patients were subsequently screened by two nurses using Tibetan translations of the CAM-ICU. With DSM-IV criterion as the reference standard, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated to assess the validity of the CAM-ICU criterion. Interrater reliability was determined by comparing the CAM-ICU ratings of nurse 1 vs. nurse 2 using the k coefficient. Results: Ninety-six patients were assessed independently by two nurses and one neurologist. According to DSM-IV standard, 42 out of 96 (43.8%) patients developed delirium. The sensitivities of Tibetan CAM-ICU were 90.5% for nurse 1 and 92.9% for nurse 2, respectively. Their specificities were 85.2% and 90.7%, respectively. The PPV were 82.6% for nurse 1 and 88.6% for nurse 2. Their NPV were 92.0% and 94.2%, respectively. The Tibetan CAM-ICU was done with good interrater reliability between nurse 1 and nurse 2 (k=0.91, P<0.001). Conclusion: The Tibetan CAM-ICU shows good validity and might be incorporated into clinical practice in Tibetan Intensive Care Units.Qu-Zhen Danzeng Na Cui Hao Wang Wen-Jun Pan Yun Long Yang-Zong Deji Cheng Ze Zeng Ren 2019Chinese Medical Journal2019,,10:4
5First 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 2021Science China(Physics,Mechanics & Astronomy)2021,64,8:3
6Singularity Robust Path Planning for Real Time Base Attitude Adjustment of Free-floating Space Robot显示文摘This paper presents a singularity robust path planning for space manipulator to achieve base(satellite) attitude adjustment and end-effector task. The base attitude adjustment by the movement of manipulator will save propellant compared with conventional attitude control system. A task-priority reaction null-space control method is applied to achieve the primary task of adjusting attitude and secondary task of accomplishing end-effector task. Furthermore, the algorithm singularity is eliminated in the proposed algorithm compared with conventional reaction null-space algorithm. And the singular value filtering decomposition is introduced to dispose the dynamic singularity, the unit quaternion is also introduced to overcome representation singularity. Hence, a singularity robust path planning algorithm of space robot for base attitude adjustment is derived. A real time simulation system of the space robot under Linux/RTAI(realtime application interface) is developed to verify and test the feasibility and reliability of the method. The experimental results demonstrate the feasibility of online base attitude adjustment of space robot by the proposed algorithm.Cheng Zhou Ming-He Jin Ye-Chao Liu Ze Zhang Yu Liu Hong Liu 2017International Journal of Automation and computing2017,14,2:3
7Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li 2014Biomedical and Environmental Sciences2014,27,5:3
8Preparation of multihollow P(St-MAA) particles by sequence soap-free/soap emulsion polymerization and followed by stepwise alkali/acid posttreatment显示文摘The effects of ionic emulsifier, sodium dodecylbenzene sulfate (SDBS), on the formation of the multihollow structures in sub-micron sized polymer particles produced by alkali/acid posttreatment were investigated. The original latex particles with narrow size distribution were synthesized by a new sequence emulsifier-free/emulsifier emulsion copolymerization of styrene (St) and methacrylic acid (MAA). Results indicated that the pore size decreased and the pore number increased with the increase of SDBS amount, and the morphology of the posttreated latex particles was also significantly influenced by the introducing time of SDBS in the preparation of the original latex particles, and a suitable introducing time was 3 h of polymerization.Rong Long Li Cheng You Kan Ze Ping Li Yi Du Yan Nan Cui 2007Chinese Chemical Letters2007,18,6:3

11A QoE-based cell range expansion scheme in heterogeneous cellular networks显示文摘Deploying low-power nodes(LPNs) overlaid with Macro cells is a promising strategy to improve the coverage and capacity of cellular systems. Meanwhile, cell range expansion(CRE) scheme is proposed to select a proper serving base station(BS) for users between Macro e Node Bs and LPNs, and then offloading of traffic from Macro cell is made. In this paper, first, we introduce the LPNs deployment strategy and its activation criteria in the heterogeneous system. Then, a quality of experience(Qo E)-based CRE scheme to adjust the coverage area of LPNs adaptively is proposed. Different from the existing CRE schemes, the Qo E values for different users with different services are considered when the users try to select an appropriate serving BS. Finally, simulation results demonstrate that the proposed scheme can improve cell edge user experience for various services as well as overall system performance.YUAN TingTing FEI Ze Song LI Na WANG Ni Wei XING Cheng Wen LIU Jia Kang 2015Science China(Information Sciences)2015,58,8:2
