Chinese Science Bulletin 2002年第3期47卷 239-243页

作者： YUAN Wanming wang shicheng LI Shengrong YANG Zhiqiang Institute of High Energy Physics Chinese Acadeny of SciencesBeijing 100039China China University of Geosciences Beijing 100083China Exploration and Production Research Institute SINOPECBeijing100083China

This work makes the quantitative constrain on tectonizations of the Gangdese block, south Qinghai-Tibetan Plateau. Apatite fission track (AFT) dating analyses of 15 samples collected across the Gangdese block show that the Gangdese block went through two periods of tectonizations, during -37.2-18.5 Ma and 18.5 - 8.0 Ma in the south Gangdese block, and during -47.6-5.3 Ma and 5.3-0 Ma in the middle Gangdese block. Different upliftings did not take place in the first period and rapid uplifting occurred in the late period. Meantime, there are some differences be-tween the south and middle Gangdese block. Their uplifting rate is 180 m/Ma and 70 m/Ma respectively. The rapid up-lifting time in the middle Gangdese block lagged behind the time in the south Gangdese block. It is Chala-Jiacuo-Riduo fault zone that is similar to the Yarlung Zangbo fault zone in control of the tectonization.

Finite-time control with H-infinity constraints of linear time-invariant and time-varying systems

引用

控制理论与应用（英文版） 2013年第2期11卷 165-172页

作者： Yang GUO Yu YAO shicheng wang Baoqing YANG Kai LIU Xin ZHAO Department of Research Xi'an Research Institute of High-Tech Control and Simulation Center Harbin Institute of Technology

This paper presents finite-time control methods with H-infinity constraints for linear time-invariant （LTI） and time-varying （LTV） systems. The basic idea of the proposed approaches is to construct controllers for the LTI and LTV in such a way that a constant quadratic Lyapunov function and a time-varying quadratic Lyapunov function can be used to establish the finite-time stability and the H-infinity performance of the resulting closed-loop systems. It is shown that the control laws can be obtained by solving a set of linear matrix inequalities （LMIs） and Differential Riccati Inequalities （DRIs） that are numerically feasible with commercially available software. Finally, the results are illustrated by application to the design of guidance law for a class of terminal guidance system.

HCCDB: A Database of Hepatocellular Carcinoma Expression Atlas

Genomics, Proteomics & Bioinformatics 2018年第4期16卷 269-275页

作者： Qiuyu Lian shicheng wang Guchao Zhang Dongfang wang Guijuan Luo Jing Tang Lei Chen Jin Gu MOE Key Laboratory of Bioinformatics Beijing National Research Center for Information Science and TechnologyBioinformatics Division Department of Automation Tsinghua University International Co-operation Laboratory on Signal Transduction Eastern Hepatobiliary Surgery Institute Second Military Medical University

Hepatocellular carcinoma （HCC） is highly heterogeneous in nature and has been one of the most common cancer types worldwide. To ensure repeatability of identified gene expression patterns and comprehensively annotate the transcriptomes of HCC, we carefully curated 15 public HCC expression datasets that cover around 4000 clinical samples and developed the database HCCDB to serve as a one-stop online resource for exploring HCC gene expression with userfriendly interfaces. The global differential gene expression landscape of HCC was established by analyzing the consistently differentially expressed genes across multiple datasets. Moreover, a 4D metric was proposed to fully characterize the expression pattern of each gene by integrating data from The Cancer Genome Atlas （TCGA） and Genotype-Tissue Expression （GTEx）. To facilitate a comprehensive understanding of gene expression patterns in HCC, HCCDB also provides links to third-party databases on drug, proteomics, and literatures, and graphically displays the results from computational analyses, including differential expression analysis, tissue-specific and tumorspecific expression analysis, survival analysis, and co-expression analysis. HCCDB is freely accessible at http：//***/database/hccdb.

A Numerical Study of the Evolution of a Mesoscale Convective Vortex on the Meiyu Front

引用

Acta meteorologica Sinica 2013年第6期27卷 889-909页

作者：王金鑫潘益农王石成 School of Atmospheric Sciences Nanjing UniversityKey Laboratory for Mesoscale Severe Weather/Ministry of Education Lianyungang Meteorological Bureau

The Advanced Research WRF（Weather Research and Forecasting） model is used to simulate the evolution of a mesoscale convective vortex（MCV） that formed on the Meiyu front and lasted for more than two days. The simulation is used to investigate the underlying reasons for the genesis, intensification, and vertical expansion of the MCV. This MCV is of a type of mid-level MCV that often develops in the stratiform regions of mesoscale convective systems. The vortex strengthened and reached its maximum intensity and vertical extent（from the surface to upper levels） when secondary organized convection developed within the mid-level circulation. The factors controling the evolution of the kinetic and thermal structure of the MCV are examined through an analysis of the budgets of vorticity, temperature, and energy. The evolution of the local Rossby radius of deformation reveals the interrelated nature of the MCV and its parent mesoscale convective system.
