3β-decay Study of Tz=-3/2Proton-rich Nucleus 29S显示文摘The exotic decay of nuclei far from the stability has recently become a hot topic of nuclear structure research.The nuclide 29S is not well investigated in the A=4n+1,Tz=-3/2series of strong+β-delayed proton precursors.The decay schemes of these nuclei are characterizedZHONG Fupeng XU Xinxing LIN Chengjian WANG Jiansong LI Zhihuan YANG Lei MA Nanru WANG Dongxi WEN Peiwei SUN Lijie WU Hongyi LUO Diwen WU Chenguang JIANG Ying LIU Yang ZANG Hongliang LIANG Pengfei LI Pengjie LI Xiaojing ZHAO Qingqing SHI Guozhu MA Junbing MA Peng YU Gongming Dipikap Patel BAI Zhen YANG Feng JIA Huiming ZHANG Huanqiao WANG Jianguo YANG Yanyun MA Weihu HU Qiang JIN Shuya ZHOU Xiaohong LI Ren HOU Dongsheng LIU Minliang HU Zhengguo MA Xinwen YANG Weiqing GAO Zhihao DUAN Fangfang YU Yuechao WANG Yufeng WANG Peng ZHOU Qingwu CUI Danteng WANG Xiang HU Liyuan PAN Min ZHANG Gaolong WANG Xiaoyu 2017Annual Report of China Institute of Atomic Energy2017,,1:0
4Three Gorges Dam:the changing trend of snail density in the Yangtze River basin between 1990 and 2019显示文摘Background The area of Oncomelania hupensis snail remains around 3.6 billion m^(2),with newly emerging and reemergent habitats continuing to appear in recent years.This study aimed to explore the long-term dynamics of snail density before and after the operation of Three Gorges Dam(TGD).Methods Data of snail survey between 1990 and 2019 were collected from electronic databases and national schistosomiasis surveillance.Meta-analysis was conducted to estimate the snail density.Joinpoint model was used to identify the changing trend and inflection point.Inverse distance weighted interpolation(IDW)was used to determine the spatial distribution of recent snail density.Results A total of 3777 snail survey sites with a precise location of village or beach were identified.For the downstream area,snail density peaked in 1998(1.635/0.11 m^(2),95%CI:1.220,2.189)and fluctuated at a relatively high level before 2003,then declined steadily from 2003 to 2012.Snail density maintained lower than 0.150/0.11 m^(2) between 2012 and 2019.Joinpoint model identified the inflection of 2003,and a significant decreasing trend from 2003 to 2012 with an annual percentage change(APC)being−20.56%(95%CI:−24.15,−16.80).For the upstream area,snail density peaked in 2005(0.760/0.11 m^(2),95%CI:0.479,1.207)and was generally greater than 0.300/0.11 m2 before 2005.Snail density was generally lower than 0.150/0.11 m^(2) after 2011.Snail density showed a significant decreasing trend from 1990 to 2019 with an APC being−6.05%(95%CI:−7.97,−7.09),and no inflection was identified.IDW showed the areas with a high snail density existed in Poyang Lake,Dongting Lake,Jianghan Plain,and the Anhui branch of the Yangtze River between 2015 and 2019.Conclusions Snail density exhibited a fluctuating downward trend in the Yangtze River basin.In the downstream area,the operation of TGD accelerated the decline of snail density during the first decade period,then snail density fluctuated at a relatively low level.There still exists local areas with a high snail density.Long-term control and monitoring of snails need to be insisted on and strengthened.Yanfeng Gong Yixin Tong Honglin Jiang Ning Xu Jiangfan Yin Jiamin Wang Junhui Huang Yue Chen Qingwu Jiang Shizhu Li Yibiao Zhou 2023Infectious Diseases of Poverty2023,12,2:0

6AUTOMATIC RECOGNITION OF FREIGHT CAR NUMBER显示文摘This paper discusses methods for character extraction on the basis of statistical and structural features of gray_level images,and proposes a dynamic local contrast threshold method accommodating to line width.Precise locating of character string is realized by exploiting horizontal projection and character arrangements of binary images in horizontal and vertical directions respectively.Also discussed is the method for segmentation of characters in binary images,which is based on projection taking stroke width and character sizes into account.A new method for character identification is explored,which is based on compound neural networks.A complex neural network consists of two sub_nets,the first sub_net performs self_association of patterns via 2_dimentional local_connected 3_order networks,the second sub_net,linking with a locally connected BP networks,performs classification.The reliability of the network recognition is reinforced by introducing conditions for identification denial.Experiments confirm that the proposed methods possess the advantages of impressive robustness,rapid processing and high accuracy of identification.FU Zhongliang Bian Fuling Zhou Songtao Hu Qingwu 2000Geo-Spatial Information Science2000,3,3:0
7Serologic study on the outbreak of acute upper respiratory tract infections caused by adenovirus 3显示文摘From April to June,2004,an outbreak of acute upper respiratory tract infections(AURTI)occurred in the north area of Jiangsu Province,China.Twenty throat swabs were collected with 13 of them presenting an adenovirus(Ad)-like cytopathogenic effect on HEp-2.These were verified as Ad by the electron microscope,direct immunofluorescence assay and Ad primer-mediated PCR.Moreover,they were identified as adenovirus type 3(Ad3)by type-specific PCR and sequencing of the amplification products.Subsequent serologic studies were carried out to finally diagnose and document the outbreak.The neutralization test of paired serum of six in nine cases show obviously increased antibodies titers.The positive rate of IgM,IgG and recovery phase neutralization antibodies of the cases were 3.7%,44.4%and 59.5%respectively while those of the controls were 0%,8.3%and 33.3%respectively.The P values of Chi-Square were 0.510,0.018 and 0.226 respectively.The concordance between IgG detected by ELISA and neutralization anti bodies detected by the neutralization test was 61.4%and the P value of Kappa was 0.070.By the serologic study,we can definitively diagnose that this outbreak of acute respiratory infections was caused by Adenovirus 3.JIANG Lufang JU Liwen JIANG Renjie LIN Yuzun ZHOU Liandi YU Shunzhang JIANG Qingwu 2007Frontiers of Medicine2007,1,2:0
8Using RAPD in Neisseria gonorrhoeae genotyping and transmission detection显示文摘The aim of this paper is to develop an applic-able Random Amplified Polymorphic DNAs(RAPD)method for genotyping Neisseria gonorrhoeae strain,and discuss the possibility of using the RAPD method to trace N.gonorrhoeae strain transmission route.Four different pretreatment methods were used on the N.gonorrhoeae genomic DNA component,and the best adaptive extract method was selected for RAPD.Different RAPD primers sequence was used for amplification and their differenti-ating capabilities for N.gonorrhoeae strains were com-pared.Applicable RAPD primer was selected for N.gonorrhoeae genotyping and then applied into transmis-sion detection.The results show that the so called cetyl-trimethylammonium bromide(CTAB)method for extracting genomic DNA could give integrated genomic DNA and give out relatively better RAPD fingerprint maps,subsequently,using selected RAPD primer could give out a group of amplification polymerase chain reac-tion bands.The fingerprint maps from different N.gonor-rhoeae strains were distinctive.Some main segments were common to all the N.gonorrhoeae strains tested.Some segments were different among the N.gonorrhoeae strains.According to the fingerprint maps and similarity index of different N.gonorrhoeae isolates,isolates from a pair of sex-partners were very similar.Based on these findings,the best extracting method and suitable RAPD primer were chosen.The RAPD fingerprint maps could type N.gonorrhoeae effectively and could be used as an additional approach in molecular epidemiology for tracing infection sources.Tiejun ZHANG Xiaoming ZHOU Tao ZHANG Yue CHEN Shunzhang YU Qingwu JIANG 2008Frontiers of Medicine2008,2,3:0
