| 1 | In situ stress state and seismic hazard in the Dayi seismic gap of the Longmenshan thrust belt显示文摘In the Longmenshan thrust belt,the Dayi seismic gap,an area with few earthquakes,is located between the ruptures of the 2008 Wenchuan Earthquake and the 2013 Lushan Earthquake,with a length of approximately 40–60 km.To date,however,the extent of the seismic hazard of the Dayi seismic gap and whether this gap is under high stress are still hotly debated.To further evaluate the seismic hazard of the Dayi seismic gap with regard to stress,two boreholes(1,000 and 500 m deep)were arranged to carry out hydraulic fracturing in situ stress measurement on either side of the Shuangshi-Dachuan fault zone.This zone has a high seismic hazard and the capacity to undergo surface rupture.Through the analogy of this new data with stability analysis using Byerlee’s Law and existing stress measurement data collected before strong earthquakes,the results show that the area surrounding the Shuangshi-Dachuan fault zone in the Dayi seismic gap(Dachuan Town)is in a state of high in situ stress,and has the conditions necessary for friction slip,with the potential hazard of moderate to strong earthquakes.Our results are the first to reveal the in situ stress profile at a depth of 1,000 m in the Dayi seismic gap,and provide new data for comprehensive evaluation of the seismic hazard in this seismic gap,which is of great significance to explore the mechanism of earthquake occurrence and to help mitigate future disaster. | Bing LI Furen XIE Jinshui HUANG Xiwei XU Qiliang GUO Guangwei ZHANG Junshan XU Jianxin WANG Dawei JIANG Jian WANG Lifeng DING | 2022 | Science China Earth Sciences2022，65，7： | 3 |
| 2 | High pressure effects on the crystal structure andelectric conductivity of perovskite like (Ca/Sr)_2CuO_2Cl_2 compounds显示文摘The crystal structure stability as well as electric conductance of (Sr/Ca)_2CuO_2Cl_2 compound with K_2NiF_4 structure was investigated up to 31 GPa using diamond anvil technique. It seems that (Sr/Ca)_2CuO_2Cl_2 is quite stable under pressure but with obvious anisotropic compressibility. The equation of state (EOS) obtained shows relative large bulk modulus. | LIU QingQing WANG FuRen LI FengYing CHEN LiangChen YU RiCheng JIN ChangQing LI YanChun LIU Jing | 2008 | Chinese Science Bulletin2008，53，18： | 2 |

| 5 | An outbreak of Mycobacterium marinum infection associated with handling seabass in China显示文摘To the Editor:Mycobacterium marinum is a nontuberculous mycobacterium that can cause opportunistic infections in humans,ranging from a single cutaneous lesion to disseminated disease.[1]It was first isolated from a fish in 1926 and identified as a cause of human infection in 1951.[1]The estimated annual incidence ranges from 0.04 to 0.27 per 100,000 persons in different countries.Outbreaks of M.marinum infections related to handling fish are not common,but have also been reported. | Qing Zhao Fangfang Bao Zihao Mi Zhenzhen Wang Pengcheng Huai Qing Pan Zheng Pang Yaoming Li Nan Cao Xiaotong Xue Buyan Li Xuechao Chen Jinliang Wang Yanxia Cui Wenqian Chang Yuan Zhang Zhenhua Yue Yongxia Liu Zhenhua Wang Weiguo Yan Jinyong Li Hongqing Tian Xianmei Lu Guizhi Zhou Jianjun Liu Hong Liu Furen Zhang | 2022 | Chinese Medical Journal2022，135，21： | 1 |
| 6 | Detecting HI Galaxies with Deep Neural Networks in the Presence of Radio Frequency Interference显示文摘In the neutral hydrogen(H I)galaxy survey,a significant challenge is to identify and extract the H I galaxy signal from the observational data contaminated by radio frequency interference(RFI).For a drift-scan survey,or more generally a survey of a spatially continuous region,in the time-ordered spectral data,the H I galaxies and RFI all appear as regions that extend an area in the time-frequency waterfall plot,so the extraction of the H I galaxies and RFI from such data can be regarded as an image segmentation problem,and machine-learning methods can be applied to solve such problems.In this study,we develop a method to effectively detect and extract signals of H I galaxies based on a Mask R-CNN network combined with the PointRend method.By simulating FAST-observed galaxy signals and potential RFI impact,we created a realistic data set for the training and testing of our neural network.We compared five different architectures and selected the best-performing one.This architecture successfully performs instance segmentation of H I galaxy signals in the RFI-contaminated time-ordered data,achieving a precision of 98.64%and a recall of 93.59%. | Ruxi Liang Furen Deng Zepei Yang Chunming Li Feiyu Zhao Botao Yang Shuanghao Shu Wenxiu Yang Shifan Zuo Yichao Li Yougang Wang Xuelei Chen | 2023 | Research in Astronomy and Astrophysics2023，23，11： | 0 |

| 9 | Scaling of ac susceptibility and the nonlinear response function of high-temperature superconductors显示文摘The amplitude-dependent ac susceptibility of high-temperature superconductors is shown to obey some empirical scaling relations. We try to analyze this behavior by extending a dc nonlinear response function of mixed state to the ac cases. The derived equations for critical current and ac susceptibility x(T) agree with the scaling relations of experimental data. | CHEN Kaixuan NING Zhenhua XU Hengyi QI Zhi LU Guo WANG Furen YIN Daole | 2005 | Science China(Physics,Mechanics & Astronomy)2005，48，1： | 0 |
