Structural study of the interaction between Homo sapiens importin αand proteins of Influenza A Viruses

流感病毒(Influenzaviruses)，属正粘病毒科，是一种RNA病毒，它在感染人，动物后能引起一种急性呼吸道传染病—流感，严重时可导致死亡。流感病毒感染宿主细胞的过程中，与病毒的复制，转录相关的蛋白需要进入到宿主细胞核内，才能发挥其功能。而这些蛋白的入核过程，大都是通过经典的入核途径。蛋白上的核定位信号序列（NLS）与Importinα蛋白结合，被转运入核，进而实现其功能。流感病毒一些蛋白与Importinα蛋白的结合，还影响了流感病毒的宿主范围。所以，通过结构生物学的方法，研究流感病毒生活史中，与Importinα蛋白相互作用的蛋白，同Importinα蛋白结合的结构。从而为更进一步...Influenza viruses were named Orthomyxoviridae because of their ability to bind to mucus and to distinguish them from another family of enveloped negative-stranded RNA virus. It can infect a wide variety of avain species, humans and several other mammalian species, including swine and horse. Influenza A viruses pose a serious threat to world public health. Some proteins of influenza viruses that ar...学位：理学硕士院系专业：生命科学学院生物医学科学系_生物化学与分子生物学学号：2162007115194

Human Skeleton and Joints Extraction for Virtual Clothing Fitting

人体运动捕捉是计算机视觉领域倍受关注的一个研究热点，在智能视频监控、视频分析、动画、游戏、医学诊断和人机交互等领域均有广阔的应用前景。它包括人体的标定与跟踪和人体动作的识别与理解两个主要内容。其中，人体的标定与跟踪是运动识别和理解的基础，在人体运动捕捉中起着关键性的作用。因此，本文以虚拟试衣系统为背景，研究人体的骨架化技术与人体关节点的定位，具有重要的理论价值和实际意义。 骨架是描述物体形状和拓扑结构的一种有效手段，广泛应用于人体的描述。基于距离变换的骨架化算法对人体的骨架有较好的效果，但无法保证骨架的连通性。本文利用图像梯度的性质，通过梯度化距离变换图，着重突出了潜在的骨架点；利用距离值和...Human motion capture is a hot research in the field of Computer Vision.

On Sellers’ Liability for Quality warranties in International Sales of Goods

卖方的品质担保义务是国际贸易法中的一个重要问题。虽然很多国家在本国立法中都对这一义务进行了明确，但由于两大法系有关品质担保义务的理论基础不同，致使各国的规定也存在差异，所以依据各国国内法对国际货物贸易中出现的品质担保问题进行解释显然会造成法律适用的不确定性，给国际贸易的正常发展造成阻碍。为了减少国际贸易的法律障碍，促进国际贸易的发展，1980年联合国国际贸易法委员会在维也纳召开的外交会议上通过了《国际货物销售合同公约》（以下简称《公约》）。《公约》作为国际贸易领域非常重要的一部实体法，充分考虑到了国际货物贸易的特点，并且综合了两大法系的规定，对品质担保义务形成了自身一套比较完整的制度，获得很多...Seller’s liability for quality warranties is an important issue of international trade law. Although it was written in many countries’ sales contract law, but the regulation was not same due to the different of the theoretical basis between two legal systems. It will be uncertain if the problem of quality warranties, arisen in international cargo trade, was interpreted according to domestic law of...学位：法律硕士院系专业：法学院法律系_法律硕士(JM)学号：X20040812

Design and Implementation of A Resources Management Subsystem Using in Internet Teaching Management Plateform

网络教学平台由专业人员设计，为教师和学生及管理者提供一个教学、学习、管理环境。实践性教学是大学工科教育的重要环节。然而由于实践性教学与理论教学同步进行，大量的工作由同学在课外完成，同学之间的相互沟通不畅，无法实现知识的有效共享。虽然目前国外已经有一些网络教学平台在一定程度上解决了以上问题，但多数只是针对理论教学的内容，能完成教学过程的基本任务，而对学习小组间的协调的支持不够。因此，从实践性教学各环节的具体内在联系出发，设计与实现一个以培养学生自主学习能力为特色的实践性网络教学平台成为了一个值得研究的课题。 本文首先分析了当前教学管理系统建设的现状，在此基础上提出了自己的研究目标和研究思路。系...With the education of the rapid development of information technology, teaching and learning management platform, has gradually become an important teaching tool for teaching aids. Teachers and students in teaching management platform for more and more pressing needs: high-quality teachers in high-efficiency can not be separated from the preparation rich teaching resources; improve the information...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201223033

modern Chinese literary theory and classical German aesthetics

德国古典美学进入中国语境后，对中国现代文论的萌生和发展起着重大的影响。对于这一重要的文学现象，国内学者对它的专题研究尚嫌不够。本论文以史实为据，从知识学层面探索、辨析1904至1949年间中国现代文论与德国古典美学之间的深层关联。论文对两者之间这种关联进行了相对全面和深入的研究，既展示德国古典美学对中国现代文论的显性或隐性影响，又尽力揭示中国现代文论自身生成和发展的新面貌。 论文第一章研究德国古典美学在现代中国的传播状况，从整体上考察中国现代学人与德国古典美学的精神遇合，及中国现代文论呈现出的崭新质素。 第二章探讨文学观念论，从文学的本质、文学的价值和文学的发生三个方面阐述中国现代文论与德...After having been introduced into China, classical German aesthetics has influenced the germination and development of modern Chinese literary theory greatly. It is an important literary phenomenon, but the monographic studies on it given by internal scholars are far more enough. This dissertation, based on the historical facts, explores and discriminates the deep relations between modern Chinese ...学位：文学博士院系专业：人文学院中文系_文艺学学号：1022006015289
