Research on introduction of Smart Beta products in A-Share Market ——Based on the empirical research of A-share Smart Beta Indexes

指数并不特指具有特定编制方法的指数，其主要是通过对传统市值加权指数在选股和权重分配方面进行优化，在指数化管理的同时，力求相比传统市值加权指数能够产生超额收益，它代表的是对传统投资理念和指数投资理念进行融合的趋势。虽然国外发达市场SmartBeta产品已初具规模，但国内仍处于起步阶段，占指数类产品的整体规模偏低，如何借鉴海外经验并基于A股实践，筛选符合现阶段国内投资者偏好的SmartBeta指数进行产品开发已成为当下国内资产管理机构面临的重大机遇。本文首先梳理指数化投资的理论演变过程，并介绍指数基金的基本概念、分类与评价体系。紧接着分析国内外市场指数产品，尤其是SmartBeta产品发展的历史与...the fusion trend of traditional investment theories and Passive index investment. Although Smart Beta products have taken a significant proportion of index products in overseas market, they are still in their infancy stage in domestic market. How to learn from overseas counterparts and develop some suitable Smart Beat products in accordance with the present stage of A-share market has become a big...学位：工商管理硕士院系专业：管理学院_工商管理硕士(工商管理硕士)学号：1792013115077

Structural Studies of Nuclear Receptor Nur77 Dimerization

核受体超家族是一类进化上相关并且能够与特定的DNA片段相互结合的转录因子。隶属于这一超家族的孤儿核受体Nur77，在各种不同刺激的诱导下，调控细胞生长、分化、凋亡，并在生物体发育的过程中发挥重要的作用，近年来已经成为一个重要的潜在药物靶点被广泛地研究。典型的核受体在受到特定的刺激下，若与相应配体结合，会以其配体结合结构域(LBD)为主发生同源或异源二聚化，并通过与DNA上被称之为应答元件的特定序列结合，发挥转录激活的生理功能。Nur77能够以单体、同源二聚体、异源二聚体三种方式分别与相应的应答元件结合，然而其具体的二聚化机理尚未被揭示。 第一个部分的研究中，我们研究已经被本实验室解析、具有高...Nuclear receptor superfamily consists of transcription factors that are evolutionarily related and can interact with specific DNA fragments.

FPGA-based hardware design for scale-invariant feature transform

[[abstract]]This paper proposes a novel hardware design method of scale-invariant feature transform (SIFT) algorithm for implementation on field-programmable gate array (FPGA). To reduce the computing costs, Gaussian kernels are calculated offline for use in Gaussian filters. To eliminate low-contrast points, the inverse of a Hessian matrix is required for hardware implementation, which results in poor performance because dividers are needed. To solve this problem, this paper presents a new mathematical derivation model to implement the low-contrast detection, avoiding the use of any dividers. For the implementation of the normalization module, a large number of dividers are required by traditional methods, which adversely affects the computational efficiency. This paper presents a new architecture using only one divider to implement the normalization function in hardware. Thanks to the parallel processing architecture proposed to design the image pyramid, SIFT detection, and SIFT descriptor, the computational efficiency of the SIFT algorithm is significantly improved. As a result of the proposed design method, the requirement of logic elements in the FPGA hardware is greatly reduced and system frequency is significantly increased. Experimental results show that the proposed hardware architecture outperforms existing techniques in terms of resource usage and computational efficiency for real-time image processing.[[notice]]補正完

Research on Ambiguity grade of the Noun in Modern Chinese

歧义度是本文的核心论题，我们对其理论背景、定义、计算方法和影响因素做了系统论述。歧义度源于计算机词义消歧，词义消歧指用计算机自动给多义词标注一个确定的义项，是自然语言处理领域一个十分重要又十分困难的课题，也是当前研究的热点问题。我们注意到不同多义词的消歧结果差异巨大，有的多义词可以轻易得到很高的消歧正确率，有的词则难以实现。多义词这种体现在词义消歧难易程度的差异是由其内在语义属性决定的，这种内在属性就是歧义度。 在词汇语义学视角下，歧义度可以看做多义词的一个客观状况，它体现多义词义项间组合关系差异大小，在更深层次上体现了义项间语义关系亲疏远近的差异，多义词义项组合关系趋同则其歧义度高，反之就...Ambiguity grade is the core topic of this article. In the research, we systematically discussed and analyzed its theoretical background, definition, calculation methods and influence factors. Ambiguity grade derives from computer word sense disambiguation which means automatic sense tagging to polysemous words by computer. We note that there are huge differences of disambiguation results among dif...学位：文学博士院系专业：人文学院中文系_汉语言文字学学号：1022008015038

Development and Clinical Trial of a High-Sensitive and Broad-Spectrum Immunoassay for Hepatitis B Surface Antigen

我国由于HBV感染者众多，存在一定比例的低病毒载量的无症状携带者及感染早期的带毒者；而其也成为了HBV输血后传播的主要来源，这种情况无疑对HBsAg诊断试剂的灵敏度提出了更高的要求。同时，众多的感染者也为突变毒株的出现提供了温床；尤其是近年来乙肝疫苗、免疫球蛋白及核苷类药物等的广泛应用更加快了HBsAg突变株尤其是“a”表位突变株的出现。而传统的HBsAg诊断试剂主要采用针对“a”表位的特异性抗体，对突变毒株的检出能力有限，加之部分突变株不能被现有疫苗保护，从而给临床诊断和血液安全带来巨大威胁。当前欧美推出的一些改进型HBsAg检测试剂已经能检出部分HBsAg突变株，但是其检测灵敏度与检测野生...China is a high-endemic area of HBV in which there are many AsCs with low viral load and newly infected persons in the window phase who are the main source of transfusion- transmitted HBV. Consequently, HBsAg assays with higher sensitivity need to be developed to overcome this problem. Meanwhile, such a vast number of infected individuals are reservoirs of HBV mutants.

“大跃进”时期农具改革运动透析

“大跃进“时期的农具改革,其源头可以追溯到建国初期的农具改良工作,后来在1957年冬掀起的全国水利建设浪潮中逐渐走向高潮,从日常的农业生产工具再到生活工具,波及面较广。在“左“的思想引领下,农具改革坚持政治挂帅、大搞群众运动、利用土法上马、发动各地互相协作以及开展竞赛等实现途径,虽然一定程度上激发了群众的创造性并取得了一定成绩,不过也造成了人力、物力和财力的较大浪费。因时代条件的限制,当这场运动落下帷幕时,并没有从根本上改变我国农业技术落后的局面,留给后来者的是不断的反思。2011年国家社会科学基金项目“新中国十二个五年计划和马克思主义中国化研究”(项目编号:11BKS021

跨国银行的国际监管

随着银行的跨国扩张和国际金融创新浪潮的高涨，一国对跨国银行的单独监管难以奏效，由跨国银行倒闭引发的银行信用危机乃至金融危机此起彼伏，各国监管当局逐渐形成共识：舍联合监管别无他途。以划分各国监管责任、统一各国监管标准和协调各国监管行动为主要目标的巴塞尔委员会及其协议、建议、报告和原则因此应运而生，欧美、日本等国均以巴塞尔协议的原则和标准为基础出台各自的监管措施

Design and Implementation of Equipment Resume Information Management System

近年来，随着贵州省经济的飞速发展，进出港的航班逐年增加，贵州空域的航线压力越来越大，造成了对贵州空管分局设备保障工作巨大的压力。同时随着民航航管管制工作方式的逐渐转型，就对现如今设备安全保障工作提出了更高更严格的要求。目前空管设备管理部门普遍采用的是较为落后的只依靠人工对设备信息进行的管理模式，此模式不仅效率低下，而且存在诸多的弊端。为了有效改善这种落后的设备管理模式，专门借用目前国内外最新的信息化管理体系，对现今陈旧的设备履历信息系统进行电子化变革迫在眉睫。 本论文对民航贵州空管分局目前所面临的单依靠人工方式对设备信息管理的模式进行了深入的探讨，同时就目前运行设备履历管理方式存在的弊端和不...In recent years, there are the rapid development of economy in GuiZhou .And the flights have increased year by year.
