| 1 | A Remote Sensing-based Analysis on the Impact of Wenchuan Earthquake on the Core Value of World Nature Heritage Sichuan Giant Panda Sanctuary显示文摘In this study,we used remotely sensed data,GIS modeling,and statistical methods to evaluate the damage caused by the Wenchuan Earthquake (May 12,2008) to the giant panda (Ailuropoda melanoleuca) habitat in the World Nature Heritage Sichuan Giant Panda Sanctuary (WHSGPS) in China.A landscape ecological analysis found increases of landscape heterogeneity,complexity,and fragmentation in the giant panda habitat after the earthquake.A terrain analysis found that slope and elevation are directly associated with the distribution of the damaged areas.As slope and elevation increase,the size of the damaged area keeps increase until to a peak,and then starts to drop.The total area of the damaged vegetation in our study area is 114.26 km 2,accounting for 3.78% of the study area;30.46% of that 114.26 km 2 is located in the Core Zone of WHSGPS.There are 18.57km 2 of the damaged vegetation located in the identified suitable giant panda habitat,accounting for 1.75% of the total area of suitable giant panda habitats in the study area.Based on these findings,we conclude that the Wenchuan Earthquake does not have significant impact on the WHSGPS as a whole. | YU Hu ZHAO Yongtao MA Yuewei SUN Yulian ZHANG Hu YANG Shihong LUO Yong | 2011 | Journal of Mountain Science2011,8,3: | 8 |
| 2 | Essential role of the CUL4B ubiquitin ligase in extra-embryonic tissue development during mouse embryogenesis显示文摘CUL4B ubiquitin ligase 基因的变化有原因地被连接到 syndromic X 连接智力迟钝(XLMR ) 。然而,在 neuronal 和发展缺点的 CUL4B 变化的病原的角色没被理解。我们与 Cul4b 的指向的混乱产生了老鼠,并且与显著生长抑制观察了胚胎的致命性并且在胚胎外的纸巾增加了 apoptosis。Cul4b,然而并非它的 paralog Cul4a,在胚胎外的纸巾驿站培植在高水平被表示。在一根胚胎外的房间线的 CUL4B 表示的 Silencing 导致了 CUL4 底层 p21 Cip1/WAF 和 G2/M 房间周期逮捕 Cip1/WAF 。Cul4b 的 Epiblast 特定的删除阻止了胚胎的致命性并且产生了可行 Cul4b 空老鼠。因此,当时在胚胎非必需合适, Cul4b 在胚胎外的纸巾执行一个必要发展角色。我们的学习提供策略产生可行 Cul4b 缺乏的老鼠为潜在的 neuronal 和人的 CUL4B XLMR 病人的行为的缺乏建模。 | Liren Liu Yan Yin Yuewei Li Lisa Prevedel Elizabeth H Lacy Liang Ma Pengbo Zhou | 2012 | Cell Research2012,22,8: | 6 |
| 3 | Neutron halo state of ^(13)C显示文摘Angular distributions for the 12C(d, p)13C transfer reactions have been measured at Ed = 11.8 MeV, and compared with those of the DWBA calculations. By means of this comparison, density distributions of the last neutron in the ground state and the first 1/2+ state of 13C are extracted. The properties of these states in 13C have also been studied in the framework of the nonlinear relativistic mean-field theory with NL-SH parameters. It is found that the first l/2+ state in 13C is a neutron halo state shown by both the experimental and theoretical density distributions of the last neutron. | LIU Zuhua, LIN Chengjian, LI Zhichang, ZHANG Huanqiao, CHEN Baoqiu, MA Zhongyu, WU Yuewei, LIU Jiancheng & LI ShuyuanChina Institute of Atomic Energy, Beijing 102413, China | 2001 | Chinese Science Bulletin2001,46,1: | 3 |
| 4 | Effects of Varicella Vaccine Time of First Dose and Coverage of Second Dose--Beijing and Ningbo,China,2012-2018显示文摘What is already known about this topic?The effectiveness of the two-dose vaccination schedule of varicella is better than that of one dose,but the vaccination schedule and coverage of varicella varies based on provinces in the mainland of China and has differing effects.What is added by this report?Earlier vaccination of the first dose may reduce the varicella incidence,and improving the vaccination coverage rates of the second dose will further reduce the varicella incidence.What are the implications for public health practice?Taking the first dose of vaccination promptly at 12 months old and improving the coverage of second dose of vaccination may play an important role in varicella prevention and control in China. | Yuewei Chen Rui Ma Yunyan Zhang Xudong Li Dapeng Yin | 2020 | China CDC weekly2020,2,36: | 2 |
| 5 | Epidemiological Characteristics of Osteoarthritis in Yichang City—Hubei Province,China,2017–2018显示文摘Summary What is already known about this topic?OA has been listed as the fastest increasing major public health problem and ranked second as a cause of disability by World Health Organization(WHO).With population aging,osteoarthritis(OA)is causing an increased economic burden for individuals and society and is attracting an increasing amount of scientific attention. | Yingying Zhang Jiajuan Yang Tanchun Yu Li Ma Yuewei Cheng Xudong Li | 2021 | China CDC weekly2021,3,16: | 2 |
| 6 | A flexible BiFeO_(3)-based ferroelectric tunnel junction memristor for neuromorphic computing显示文摘Ferroelectric tunnel junctions(FTJs)as the artificial synaptic devices have been considered promising for constructing brain-inspired neuromorphic computing systems.However,the memristive synapses based on the flexible FTJs have been rarely studied.Here,we report a flexible FTJ memristor grown on a mica substrate,which consists of an ultrathin ferroelectric barrier of BiFeO_(3),a semiconducting layer of ZnO,and an electrode of SrRuO_(3).The obtained flexible FTJ memristor exhibits stable voltage-tuned multistates,and the resistive switchings are robust after 10^(3) bending cycles.The capability of the FTJ as a flexible synaptic device is demonstrated by the functionality of the spike-timing-dependent plasticity with bending,and the accurate conductance manipulation with small nonlinearity(-0.24)and low cycle-to-cycle variation(1.77%)is also realized.Especially,artificial neural network simulations based on experimental device behaviors reveal that the high recognition accuracies up to 92.8%and 86.2%are obtained for handwritten digits and images,respectively,which are close to the performances for ideal memristors.This work highlights the potential applications of FTJ as flexible electronics for data storage and processing. | Haoyang Sun Zhen Luo Chuanchuan Liu Chao Ma Zijian Wang Yuewei Yin Xiaoguang Li | 2022 | Journal of Materiomics2022,8,1: | 2 |
