    Myopodin是最新发现的synaptopodin蛋白家族的第二个成员。除了synaptopodin蛋白外,它和已知的蛋白没有明显的同源关系。Myopodin在氨基酸序列的N端及C端分别具有一个经典的入核信号(NLS),同时在氨基酸序列的410-563位之间还有一个肌动蛋白(actin)结合位点,可以直接与肌动蛋白相互作用,因此它是一种结构蛋白。Myopodin也是一种细胞核质蛋白,其在细胞核质中的分布受分化和应激的调控。为了进一步研究Myopodin蛋白的功能,我们首先制备其抗体。构建了融合表达载体pGEX4T2-N-Myopodin。将构建好的表达载体转化大肠杆菌并诱导表达,把表达的N-...Myopodin is the second member of the synaptopodin protein family. It shows no significant homology to any known protein except synaptopodin. myopodin contains two classic nuclear localization signals (NLSs), at its N-terminus and C-terminus respectively.There is an actin-binding site at the position of aa 410-563 that can interact with actin directly. Myopodin is a dual compartment protein which r...学位:理学硕士院系专业:生命科学学院生物学系_生物化学与分子生物学学号:20032611

    市场约束是《新巴塞尔协议》提出的强化银行监管的三大支柱之一,也是我国建立现代的银行监管体系的重要目标和手段。目前世界金融局势动荡不安,银行体系的稳定性受到极大的冲击,国内银行业的改革也进入了攻坚阶段,在这样的大背景下检验我国商业银行的市场约束,对我国商业银行改革的进一步深化和银行监管体系的完善有丰富的指导意义。 本文首先对国内外市场约束领域的文献进行了比较全面的综述,重点介绍了国外实证方面的文献,而后明确定义了商业银行市场约束的概念,提出了股东、次级债持有人和存款人三方约束的理论框架,详细地分析了各自对商业银行实现约束的机制并介绍了一个数理模型。 在实证研究部分,本文采用非平衡面板数据的固...Market discipline is one of the three Pillars in the new Basel Accord in order to strengthen the banking supervision, which is also the means and goals to establish a modern banking regulation system in China. Nowadays the world banking stability was seriously crushed by global financial crisis and domestic banking reform is being the critical stage. Under such background, doing empirical research...学位:经济学硕士院系专业:王亚南经济研究院_金融学(含保险学)学号:2772006115282

    The Study on the Risk of Personal Loan in the A Bank

    伴随着我国居民消费、投资观念的发展,个人贷款已成为各家商业银行信贷投放的重要方面,并对改善民生、拉动内需起到重要作用。目前商业银行的公司信贷风险管理技术、手段措施较为丰富和成熟,作为我国商业银行一项重要的资产业务,个人贷款业务风险虽然已被商业银行认识,但并不如传统公司贷款业务一样受到重视,并且通常被认为是“低风险”业务。随着近年经济增速下滑、房地产市场的调整,个人贷款的风险防控面临严峻挑战。由于我国银行个人贷款业务起步时间较晚,目前没有完善的管理模式,虽然近年来已建立了一些风险管理理论,但也较为零散,急需银行界人士进一步对其研究,逐步完善现有的风险管理体系。 本文以A银行个人贷款风险管理为研...With the development of China’s consumer spending and investment concept, personal loan has become an important part of commercial banks’ credit lending, and is currently playing an important role in promoting domestic demand. At present, commercial banks are relatively mature in risk management techniques and measures of corporate loans, while personal loan, as an important asset of China’s comme...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:1792008115113

    浅析新加坡华语广告里的语用含糊现象 = Pragmatic vagueness in Singapore Chinese advertising language

    No full text
    广告语言是构成广告的重要部分之一。有时为了能吸引消费者的注意,广告商会采用某些语言策略来制造一些广告效果。广告里最常见的语言策略之一既是使用含糊的语言(语用含糊)。本文一共搜集了三十则有关健康与美容产品的新加坡华语广告,找出这些广告之中最常见的语用含糊现象。本文以Ruth Kempson的“含糊”概念为基础,把这些语用含糊现象归纳为三个类型。它们分别为“语义细节不明确类型”、“语义延伸类型”、和“多种语义解释类型”。然后,在个别类型之中进行分析,探讨这些语用含糊现象在广告之中所引起的效果。一般相信广告语境在消费者解读含有语用含糊现象的广告时,起着重要的功能。而消费者本身与消费者周遭的社会环境是构成广告语境的部分元素之一。因此,本文也将略谈消费者本身和社会环境在解读广告过程中所扮演的角色。Advertising language constitutes an important part in the advertisements. Sometimes, in order to attract the consumers’ attention on the advertisements, advertisers would adopt certain strategies in creating advertising language, so as to attain certain advertising effects. One of the most common strategies that advertisers adopt in advertising language is the usage of vague language (pragmatic vagueness). This thesis gathered a total of 30 Singapore mandarin advertisements, which are mainly related to healthcare and beauty products. Among these advertisements, several common pragmatic vagueness phenomena were identified. Based on Ruth Kempson’s concept on vagueness, the thesis classifies these commonly seen phenomena into 3 main types. The 3 types are namely “the use of words with indeterminate meanings”, “the use of words with extended meanings” and “the use of words with multiple meanings”. Following on, the thesis will also discuss the positive advertising effects of each type of pragmatic vagueness phenomena. It is believed that when the consumers were decoding the messages in the advertisements, which contain pragmatic vagueness phenomena, advertising context serves as an important function. Both the consumers and the social environment constitute part of the advertising context. Hence, the thesis will also discuss the roles of the consumers and social environment during the process when the consumers are decoding the message the advertisement is trying to deliver.Bachelor of Art

    谐波齿轮传动过程中,双圆弧齿廓可有效避免尖点啮合现象。为进一步优化双圆弧齿廓,提高谐波齿轮传动装置的性能,基于改进运动学法的精确共轭理论,采用Matlab编程计算的方法,对比分析了柔轮齿廓中主要参数的变化对共轭区域和共轭齿廓的影响。分析结果表明,柔轮轮齿凸齿廓圆弧半径、凹齿廓圆弧半径和径向变形量对共轭齿廓形状影响显著;而公切线倾角、公切线长度对共轭区间和共轭齿廓弧长影响较明显,合理选用柔轮齿廓参数可有效提升谐波齿轮装置的传动性能

    以四点接触球轴承为研究对象,针对四点接触球轴承旋转精度开展研究,提出了同时考虑轴承内圈和外圈圆度误差的轴承旋转精度数值计算方法。以轴承径向跳动量描述轴承的旋转精度,根据四点接触球轴承的结构特点及运动关系,构建了轴承径向跳动的数学模型,并基于Matlab编写程序进行仿真计算。结果表明,内圈沟道谐波阶次不变时,轴承的旋转精度会随着谐波幅值的增大而降低;当内圈谐波阶次为3即内圈沟道廓形为三棱圆时,轴承径向跳动最小,轴承旋转精度最高;当外圈圆度误差谐波次数与钢球的个数存在整倍关系时,外圈的径向跳动最大,当外圈圆度误差谐波次数是钢球个数一半的奇数倍时,外圈径向跳动的值最小
