Design and Implementation of Marine Scientific Data-sharing System Based on WEB

当今世界海洋科学相关领域各种研究活动蓬勃发展，但是海洋科学研究的基础是各类海上调查考察活动所获得的观测数据资料，因此科研数据的共享对于科研活动有着重要意义。973计划CHOICE-C项目是海洋科研领域的大型项目，涉及单位、人员都比较多。在项目的进行过程中，各个研究小组都会不断产生各类研究数据，彼此之间都希望能获得对方的数据资料以利于自己的研究，同时数据生产者又希望自己的权益得到保障。为了保证数据生产者和申请者双方的权益，项目制定了一套内部数据共享协议。协议虽然保障了各方的权益，但是也带来效率不高的问题，特别是当共享双方不在同一单位的时候，传统的、基于纸质文书申请的共享流程往往耗费数日甚至数周。...The research activities in the fields of marine science are already booming today. The data obtained from marine scientific survey activities is basic for marine scientific research. So sharing the marine scientific survey data has important significance for marine scientific researches.

Studies on Life Imprisonment—— A Perspective based on the Ninth Criminal Law Amendment

终身监禁起源于西方国家，最早是作为死刑的替代刑而提出来的。西方国家的立法大多将终身监禁规定为独立的刑种，具有较强的严厉性。终身监禁以报应刑论和目的刑论作为理论基础，在实现对罪犯的报应的同时也能达到预防的目的。我国《刑法修正案（九）》中首次引入终身监禁，这是我国慎用死刑和高压反腐的双重压力下的产物。终身监禁入刑，一方面能有力的打击贪污受贿犯罪，另一方面能限制、减少死刑的适用。 本文通过对终身监禁的产生及发展、各国终身监禁的立法现状、终身监禁的立法基础以及终身监禁与我国无期徒刑的比较等问题的探讨，对终身监禁进行了系统的介绍，结合我国当前《刑法修正案（九）》中终身监禁的规定提出一些完善终身监禁的建...Life imprisonment originated in the Western countries, was first put forward as a substitute for the death penalty. The legislation of most Western countries prescribes life imprisonment as an independent punishment, with a strong severity. Life imprisonment is based on the retribution punishment theory and objective punishment theory, in the realization of the retribution to the criminals, but al...学位：法学硕士院系专业：法学院_刑法学学号：1362015115097

Structural Studies of Pelota and p53 Upregulated Modulator of Apoptosis

1生物大分子X射线晶体学 结构生物学通过对生物大分子的结构和功能进行研究，解释生命的分子机制。X射线晶体学、核磁共振技术(NMR)和冷冻电镜(cryo-EM)三维重构是当今结构生物学的主要研究手段。这三种方法各有独到之处，又各有局限和不足。作为最早发展起来的结构生物学研究手段，X射线晶体学是目前解析蛋白质结构的主要手段。目前PDB（ProteinDataBank）中收录的蛋白结构中，大约有85%是利用X射线晶体学方法获得的。 本章对本论文重点使用的技术手段——X射线晶体学进行以下几方面的介绍：X射线晶体学的基本原理、蛋白晶体的培养、衍射数据的收集处理、相位获取的方法原理、模型构建及修正等。...1 Introduction to macromolecular X-ray crystallography Structural biology is a discipline that investigates macromolecular structure to atomic resolution and the associated functions.

经济政策不确定性对企业流动性管理的影响

我国经济进入新常态后,大量调控政策的出台,使得人们越来越关注宏观经济政策在微观层面的传导机制,并期望基于此判断政策的实施效果。实证研究发现:基于预防性动机,经济政策不确定性越显著,融资约束企业的现金持有量越高;非融资约束企业现金持有量与经济政策不确定性的关系更复杂,只有在经济繁荣期才表现出投机性。因此,一方面,政府必须进一步坚持\"宏观政策要稳\"的方针,降低企业对政策不稳定性的预期;另一方面,企业也要实施积极的流动性管理措施,以应对经济政策的不确定性。中国博士后基金第55批面上项目(2014M551844);;江西省哲学社会科学规划课题(14ZT28

Correlation of microstructure and thermo-mechanical properties of a novel hydrogen transport membrane

Thesis (Ph.D.) University of Alaska Fairbanks, 2014A key part of the FutureGen concept is to support the production of hydrogen to fuel a 'hydrogen economy,' with the use of clean burning hydrogen in power-producing fuel cells, as well as for use as a transportation fuel. One of the key technical barriers to FutureGen deployment is reliable and efficient hydrogen separation technology. Most Hydrogen Transport Membrane (HTM) research currently focuses on separation technology and hydrogen flux characterization. No significant work has been performed on thermo-mechanical properties of HTMs. The objective of the thesis is to understand the structure-property correlation of HTM and to characterize (1) thermo mechanical properties under different reducing environments and thermal cycles (thermal shock), and (2) evaluate the stability of the novel HTM material. A novel HTM cermet bulk sample was characterized for its physical and mechanical properties at both room temperature and at elevated temperature up to 1000°C. Microstructural properties and residual stresses were evaluated in order to understand the changing mechanism of the microstructure and its effects on the mechanical properties of materials. A correlation of the microstructural and thermo mechanical properties of the HTM system was established for both HTM and the substrate material. Mechanical properties of both selected structural ceramics and the novel HTM cermet bulk sample are affected mainly by porosity and microstructural features, such as grain size and pore size-distribution. The Young's Modulus (E-value) is positively correlated to the flexural strength for materials with similar crystallographic structure. However, for different crystallographic materials, physical properties are independent of mechanical properties. Microstructural properties, particularly, grain size and crystallographic structure, and thermodynamic properties are the main factors affecting the mechanical properties at both room and high temperatures. The HTM cermet behaves more like an elastic material at room temperature and as a ductile material at temperature above 850°C. The oxidation and the plasticity of Pd phase mainly affected the mechanical properties of HTM cermet at high temperature, also as a result of thermal cycling. Residual stress induced in the HTM by thermo cycles also plays a very critical role in defining the thermo-mechanical properties

Fibrewise Rational H-Spaces

We prove fibrewise versions of classical theorems of Hopf and Leray-Samelson. Our results imply the fibrewise H-triviality after rationalization of a certain class of fibrewise H-spaces. They apply, in particular, to universal adjoint bundles. From this, we may retrieve a result of Crabb and Sutherland [Proc. London Math. Soc. (2000), 747-768], which is used there as a crucial step in establishing their main finiteness result

miR-574-5p negatively regulates tumor suppressors Qki6/7 to impact the development of colon cancer

Quaking（QKI）是信号转导和RNA活化蛋白家族（STAR）的一个信号蛋白，在结肠癌组织中异常显著下调甚至缺失。最新研究表明，QKI可以通过调控p27Kip1和β-catenin等，影响Wnt信号转导、结肠上皮细胞的增殖与分化以及结肠癌的发生与发展，提示Qki是结肠癌的一个肿瘤抑制基因。然而，QKI在结肠细胞中的表达的调控机制却不清楚。 我们在研究中发现，在C57BL/6J-ApcMin/J小鼠和结肠癌病人的结肠癌组织中，miR-574-5p的表达水平显著升高，而QKI的表达水平恰与之相反且呈现负相关趋势。在小鼠、人结肠癌细胞中，过表达miR-574-5p后QKI的mRNA和蛋白表达水...The RNA-binding protein quaking (QKI) belongs to the evolutionarily conserved signal transduction and activation of RNA (STAR) family, which is significantly downregulated and even absent in some colon cancers.

带有受限缩并规则的兰贝克演算的模型论

自然语言是一个由较小语言成分逐步递增地形成较大语言成分的符号体系,这就是自然语言的毗连性(COnCATEnATIOn)。通过毗连,自然语言符号串可以逐步增长扩张,这就是自然语言的生成性(gEnErATIOn)。自然语言的毗连生成体现出由小到大的递增性,弗雷格(frEgE)用语句函项的思想来分析其构造过程,即把某一语言成分当作函项,把旁边的成分当作函项的主目,把两个成分的毗连当作函项运算国家社会科学基金项目“面向自然语言信息处理的范畴类型逻辑研究”资助(项目编号:09BZX046
