1A simplified index to assess the combined impact of tropical cyclone precipitation and wind on China显示文摘Relationships between tropical cyclone(TC)precipitation,wind,and storm damage are analyzed for China based on TCs over the period from 1984 to 2013.The analysis shows that the maximum daily areal precipitation from stations with daily precipitation of ≥50 mm and the sum of wind gusts of ≥13.9 m/s can be used to estimate the main damage caused by TCs,and an index combining the precipitation and wind gust of a TC(IPWT)is defined to assess the severity of the combined impact of precipitation and wind.The correlation coefficient between IPWT and the damage index for affecting TCs is 0.80,which is higher than that for only precipitation or wind.All TCs with precipitation and wind affecting China are divided intofive categories,Category 0 to Category 4,based on IPWT,where higher categories refer to higher combined impacts of precipitation and wind.The combined impact category is closely related to damage category and it can be used to estimate the potential damage category in operational work.There are 87.7%,72.9%,69.8%,and 73.4%of cases that have the same or one category difference between damage category and combined impact category for Categories 1,2,3,and 4,respectively.IPWT and its classification can be used to assess the severity of the TC impact and of combined precipitation and wind conveniently and accurately,and the potential damage caused by TCs.The result will be a good supplementary data for TC intensity,precipitation,wind,and damage.In addition,IPWT can be used as an index to judge the reliability of damage data.Further analysis of the annual frequency of combined precipitation-wind impact categories reveals no significant increasing or decreasing trend in impact over China over the past 30 years.Peiyan CHEN Hui YU Ming XU Xiaotu LEI Feng ZENG 2019Frontiers of Earth Science2019,13,4:9
2INTRODUCTION AND APPILICATION OF A NEW COMPREHENSIVE ASSESSMENT INDEX FOR DAMAGE CAUSED BY TROPICAL CYCLONES显示文摘Using principal component analysis,a new comprehensive assessment index for damage caused by tropical cyclones in China's Mainland is developed based on data from 1984 to 2008.it is a weighted average of four kinds of damage data:including the deaths and missing,affected crop area,destroyed houses,and rate of direct economic loss.The weighting coefficients are set by principal component analysis.Two indices are derived,which differ in the importance of the deaths and missing in severity assessment according to the sign of the second principal component of damage data.Trends in the damage caused by individual tropical cyclones and in the annual frequencies of the various levels of severity of damage caused by tropical cyclones are analyzed.no clear trend in damage from individual tropical cyclones is found.The annual frequency of tropical cyclones causing heavy and catastrophic damage shows a clear decrease from 1984 to 2008 with no trend in the total number of damaging tropical cyclones.Peiyan Chen Xiaotu Lei Ming Ying 2013Tropical Cyclone Research and Review2013,2,3:7

4PERFORMANCE OF TROPICAL CYCLONE FORECAST IN WESTERN NORTH PACIFIC IN 2016显示文摘The forecasts of tropical cyclones(TC) in 2016 from 5 official guidances, 5 global models, 3 regional models and 6 ensemble systems were assessed to study the current capabilities of track and intensity forecasts for the western North Pacific. In 2016, the position errors for each official agency were under 85, 150 and 250 km at the lead times of 24, 48, and 72 h, respectively,indicating the performance of track forecasts was a little worse than that in 2015. For each lead time, decreases were seen for each quantile value of the global models from 2010 to 2015; however, this progress in forecasts was stagnated or was reversed in 2016, especially for long lead times.A new error tracking tool,called a 'Track Error Rose',was used to visualize the spatial distributions of the track forecast error relative to the observed TC center. The results show that as lead time increases, the moving speed of most global model TC forecasts becomes slower than those of the observations, and the largest track error often appears to the south of the observation position. In 2016, JMA-GSM, NCEP-GFS, STI-GRAPES and UKMO-MetUM made considerable progress in their intensity forecasts at lead times of 24 and 48 h, and the EPS intensity forecasts made significant progress compared to those of 2015.GUOMIN CHEN XIPING ZHANG PEIYAN CHEN HUI YU RIJIN WAN 2017Tropical Cyclone Research and Review2017,6,1:4
5Interaction Between Variations in Dopamine D2 and Serotonin 2A Receptor is Associated with Short-Term Response to Antipsychotics in Schizophrenia显示文摘Dear Editor,Schizophrenia is a chronic and debilitating brain disorder,which has a strong genetic component with heritability ranging from 66%to 85%[1,2].Currently,antipsychotic drugs remain the most effective treatment for the psychotic symptoms of schizophrenia[3].Because of the severe sideeffects of first-generation antipsychotics(FGAs),secondgeneration antipsychotics(SGAs)have become more widely used in the treatment of schizophrenia.Liansheng Zhao Huijuan Wang Yamin Zhang Jinxue Wei Peiyan Ni Hongyan Ren Gang Li Qiang Wang Gavin P Reynolds Weihua Yue Wei Deng Hao Yan Liwen Tan Qi Chen Guigang Yang Tianlan Lu Lifang Wang Fuquan Zhang Jianli Yang Keqing Li Luxian Lv Qingrong Tan Yinfei Li Hua Yu Hongyan Zhang Xin Ma Fude Yang Lingjiang Li Chuanyue Wang Huiyao Wang Xiaojing Li Wanjun Guo Xun Hu Yang Tian Xiaohong Ma Jeremy Coid Dai Zhang Chao Chen Tao Li Chinese Antipsychotics Pharmacogenomics Consortium 2019Neuroscience Bulletin2019,35,6:3
62021 Chinese consensus on the diagnosis and management of primary immune thrombocytopenia in pregnancy显示文摘Immune thrombocytopenia(ITP)is an acquired disease characterized by isolated thrombocytopenia,which is one of the most common causes of thrombocytopenia during pregnancy.Women with ITP who have severe thrombocytopenia are at an increased risk for life-threatening obstetric complications.Therefore,we established this consensus statement on the diagnosis and management of ITP during pregnancy(detailed information is available in the Supplementary File,http://links.lww.com7CM9/A978).Zhang Xiaohui Chen Fangping Chen Xiequn Cheng Yunfeng Fang Meiyun Feng Jianming Fu Haixia Gao Hong Han Yue He Aili Hou Ming Hu Yu Huang Ruibin Huang Wenrong Jing Zhicheng Kong Peiyan Liang Aibin Liang Meiying Liu Daihong Liu Junling Liu Lin Liu Xiaowei Ma Liangming Mei Heng Ni Heyu Niu Ting Peng Jun Qiao Jianlin Ren Jinhai Song Yongping Tang Liang V Tong Tong Wang Shaoyuan Wang Xin Wang Zhao Wei Hui Wu Depei Wu Guangsheng Xu Caigang Xu Xue Xu Yajing Yang Linhua Yang Renchi Yang Tonghua Yin Chenghong Yu Li Zhang Guangsen Zhang Lei Zhang Liansheng Zhang Xi Zhao Weili Zhao Yongqiang Zhou Daobin Zhou Hu Zhou Zeping Zhu Tienan Wang Jianliu Huang Xiaojun 2022Chinese Medical Journal2022,,8:2
7A Potential Risk Index Dataset for Landfalling Tropical Cyclones over the Chinese Mainland(PRITC dataset V1.0)显示文摘A dataset entitled“A potential risk index dataset for landfalling tropical cyclones over the Chinese mainland”(PRITC dataset V1.0)is described in this paper,as are some basic statistical analyses.Estimating the severity of the impacts of tropical cyclones(TCs)that make landfall on the Chinese mainland based on observations from 1401 meteorological stations was proposed in a previous study,including an index combining TC-induced precipitation and wind(IPWT)and further information,such as the corresponding category level(CAT_IPWT),an index of TC-induced wind(IWT),and an index of TC-induced precipitation(IPT).The current version of the dataset includes TCs that made landfall from 1949-2018;the dataset will be extended each year.Long-term trend analyses demonstrate that the severity of the TC impacts on the Chinese mainland have increased,as embodied by the annual mean IPWT values,and increases in TC-induced precipitation are the main contributor to this increase.TC Winnie(1997)and TC Bilis(2006)were the two TCs with the highest IPWT and IPT values,respectively.The PRITC V1.0 dataset was developed based on the China Meteorological Administration’s tropical cyclone database and can serve as a bridge between TC hazards and their social and economic impacts.Peiyan CHEN Hui YU Kevin K.W.CHEUNG Jiajie XIN Yi LU 2021Advances in Atmospheric Sciences2021,38,10:2
8ITO/Cu multilayer electrodes for high-brightness electrochromic displays显示文摘Fabry-Perot(F-P)nanocavity-type electrochromic devices with multicolor tunability have attracted significant interest in the past two years for their potential uses in a wide variety of applications,such as electronic display,military camouflage,and dynamic decoration.However,challenges such as insufficient brightness,lengthy switching times,and poor cycling stability have yet to be overcome.Herein,we demonstrate electrochromic electrodes based on ITO/Cu as both the current collector and the reflective layer,with WO_(3 )as the electrochromic material,forming a unique three-layered structure.The constituted WO_(3 )/ITO/Cu films present a high brightness value of about 84%before coloration,and a decent brightness value of 48%after coloration at−0.8​V.Moreover,a fast switching time between different coloration states(tc​=​2.2​s;tb​=​1​s)is recorded,attributed to the extremely low sheet resistivity of the ITO/Cu current collector.The films also reveal excellent electrochemical cycling stability across 2000 cycles.Xueqing Tang Zishou Hu Zhen Wang Jian Chen Xinyang Mu Ge Song Peiyan Sun Zhengji Wen Jiaming Hao Shan Cong Zhigang Zhao 2022eScience2022,2,6:1

17SCGN deficiency is a risk factor for autism spectrum disorder显示文摘Autism spectrum disorder(ASD)affects 1-2%of all children and poses a great social and economic challenge for the globe.As a highly heterogeneous neurodevelopmental disorder,the development of its treatment is extremely challenging.Multiple pathways have been linked to the pathogenesis of ASD,including signaling involved in synaptic function,oxytocinergic activities,immune homeostasis,chromatin modifications,and mitochondrial functions.Here,we identify secretagogin(SCGN),a regulator of synaptic transmission,as a new risk gene for ASD.Two heterozygous loss-of-function mutations in SCGN are presented in ASD probands.Deletion of Scgn in zebrafish or mice leads to autism-like behaviors and impairs brain development.Mechanistically,Scgn deficiency disrupts the oxytocin signaling and abnormally activates inflammation in both animal models.Both ASD probands carrying Scgn mutations also show reduced oxytocin levels.Importantly,we demonstrate that the administration of oxytocin and anti-inflammatory drugs can attenuate ASD-associated defects caused by SCGN deficiency.Altogether,we identify a convergence between a potential autism genetic risk factor SCGN,and the pathological deregulation in oxytocinergic signaling and immune responses,providing potential treatment for ASD patients suffering from SCGN deficiency.Our study also indicates that it is critical to identify and stratify ASD patient populations based on their disease mechanisms,which could greatly enhance therapeutic success.Zhe Liu Shuai Tan Lianyu Zhou Li Chen Mingfeng Liu Wang Wang Yingying Tang Qin Yang Sensen Chi Peiyan Jiang Yue Zhang Yonghua Cui Junhong Qin Xiao Hu Shenglong Li Qi Liu Lu Chen Song Li Ezra Burstein Wei Li Xiaohu Zhang Xianming Mo Da Jia 2023Signal Transduction and Targeted Therapy2023,8,2:0
18ON TROPICAL CYCLONE ACTIVITY OVER THE WESTERN NORTH PACIFIC IN 2012显示文摘Tropical cyclone(TC) activity over the western North Pacific(WNP) in 2012 is summarized and the associated large-scale environmental conditions are discussed. In total 25 named storms formed in the WNP basin in 2012, among them were 3 tropical storms(TSs), 7 severe TSs, 4 typhoons, 6 severe typhoons, and 5 super typhoons. TC activity was close to a 30-year average but above the average active level of recent years since 2005. Total number of TCs formed in the South China Sea(SCS) in 2012 was below normal, with only 40% of the climatological mean. Overall, TC genesis over the WNP was characterized by four active periods. During each period TCs took distinct prevailing tracks. The periodic characteristics in TC genesis were attributed to the activity of the intraseasonal oscillation(ISO), while those in TC tracks were related to the large-scale dynamical and thermodynamic conditions induced by the enhanced WNP monsoon activity and the weak El Ni?o conditions.RUIFEN ZHAN MING YING PEIYAN CHEN 2013Tropical Cyclone Research and Review2013,2,1:0
19Evaluating the Influence of Multisource Typhoon Precipitation Data on Multiscale Urban Pluvial Flood Modeling显示文摘Based on station precipitation observations,radar quantitative precipitation estimates(QPE), and radar fusion data during Typhoon Fitow(2013), the influence of multisource precipitation data on multiscale urban typhoon pluvial flood modeling is studied. Using Shanghai, China,as the study area, a simplified 2D hydrodynamic model is applied to simulations. Combined with actual flood incidents reported by the public and soil moisture data, we perform multiscale verifications and determine the applicability of three precipitation datasets in the modeling. The results are as follows:(1) At the city scale, although QPE have higher spatial resolution, these estimates are lower than station observations. Radar fusion data have both high accuracy and high spatial resolution. For flood depths above 5 cm, the radar fusion precipitation scenario can improve the matching probability by 6%.(2) At the neighborhood scale, the radar fusion precipitation scenario can effectively mitigate the problems of an uneven spatial distribution of stations and a weak QPE to accurately capture pluvial details.(3)One fixed-point assessment shows that different precipitation data have little influence on the temporal characteristics of the modeling result-all three types of data can accurately reflect flood occurrence times. This work can provide a scientific basis for constructing effective urban pluvial flood monitoring systems.Yi Lu Jie Yin Dandan Wang Yuhan Yang Hui Yu Peiyan Chen Shuai Zhang 2022International Journal of Disaster Risk Science2022,13,6:0
20Spintronic terahertz emission with manipulated polarization (STEMP)显示文摘Highly efficient generation and arbitrary manipulation of spin-polarized terahertz(THz)radiation will enable chiral lightwave driven quantum nonequilibrium state regulation,induce new electronic structures,consequently provide a powerful experi-mental tool for investigation of nonlinear THz optics and extreme THz science and applications.THz circular dichromic spectroscopy,ultrafast electron bunch manipulation,as well as THz imaging,sensing,and telecommunication,also need chiral THz waves.Here we review optical generation of circularly-polarized THz radiation but focus on recently emerged polarization tunable spintronic THz emission techniques,which possess many advantages of ultra-broadband,high efficiency,low cost,easy for integration and so on.We believe that chiral THz sources based on the combination of electron spin,ultra-fast optical techniques and material structure engineering will accelerate the development of THz science and applications.Peiyan Li Shaojie Liu Xinhou Chen Chunyan Geng Xiaojun Wu 2022Frontiers of Optoelectronics2022,15,1:0
