Design and Implementation of Audio-Visual Management System of Wenzhou Urban Construction Archives

温州市城市建设档案馆成立于上世纪八十年代。经过三十多年的收集和发展，已经建设成为国家一级城建档案馆，并保存着海量的音视频资料、早期录像带、大量的照片等声像资料。随着多媒体时代的到来，声像档案在传统档案中的占比逐年递增，声像档案的查询利用率也在逐年递增。但是，传统的声像档案管理存在许多弊端，比如管理制度落后，库房条件差，声像档案查找不方便，利用过程中会导致原始声像档案自然损耗或丢失，不利于声像档案长期保存。所以，城建档案馆需要利用软件设计和电子设备技术，来开发一套可以使声像档案长期保存，并且查找利用方便的声像档案管理系统，为以后温州城建档案馆声像档案可持续发展和数字化档案馆发展奠定基础。 温州...Wen Zhou city construction archives was founded in the eighties of the last century.

A study on the development of China’s private banking

私人银行业务是商业银行为高净资产客户提供的以财富管理为核心的顶级专业化的一揽子服务。近些年我国的富裕阶层迅速扩大，资产管理需求强劲，私人银行业务正越来越显现出巨大的增长潜力。随着中国金融业的全面开放，具有丰富经验的外资银行也瞄准了拥有巨大潜力的中国私人银行业务市场，私人银行业务成为中外资银行竞争的焦点。由于我国在发展私人银行业务过程中受到传统观念的制约，金融管制上存在着缺陷以及银行内部的局限，私人银行业务的发展遭到瓶颈，因此本文在借鉴国外银行开展私人银行业务的经验的基础上，通过分析我国私人银行业务发展的必要性和可行性以及现阶段存在的问题，提出我国私人银行业务的发展策略。 本文主要观点及结论：...Private banking business is a finance service whose core is fortune management and provided to wealthy people by commercial bank. These years, as the rapidity of personal wealth accumulation in China, more and more rich people need wealth management service，which accounts for the huge growth potential of private banking. As the fields of finance’s opening，the foreign banks with abundance experienc...学位：经济学硕士院系专业：经济学院金融系_金融学(含保险学)学号：X200614400

Study on the thermotolerance mechanisms of Agaricus bisporus as well as the cloning and functional verification of related genes

高温胁迫(Heatstress，HS)指生物体处于超过其适宜温度范围的环境下所受到的一种非生物胁迫(Abioticstress)，它能破坏生物体正常的细胞动态平衡，导致生物体严重的生长、发育停滞，甚至死亡。随着温室效应的影响和全球变暖的趋势，高温胁迫以及与之紧密关联的干旱、渗透等胁迫已经成为导致全球性农作物减产的主要原因。本文主要研究高温胁迫对双孢蘑菇的损害，以及耐温双孢蘑菇菌株02对高温的响应和抵御机制；同时探讨了应用分子生物学和基因工程技术培育耐高温双孢蘑菇品种的可能性。 双孢蘑菇[AgaricusbisporusLange(Imbach)]是具有高经济价值和生态意义的栽培食用菌。双孢蘑...Heat stress is one type of abiotic stress, which caused by high environmental temperature beyond optimum. Heat stress could disturb the cellular homeostasis of organisms, leading to sever stagnation in growth, development, and even death. As the global climate getting warmer, heat stress becomes the main cause for the great reduction in agriculture and breeding.

Research on the Dimerization Sequence of Exo70 and Its Role in Breast Cancer Cell Metastasis

Exo70是胞外分泌复合体Exocyst的关键亚基,可通过参与Exocyst复合体或自身聚合促进细胞迁移。我们在研究中发现,Exo70自身形成二聚体的能力显著强于与Exocyst其它7个亚基的结合,提示Exo70二聚化的重要作用。进一步构建Exo70缺失突变体,并通过一系列免疫共沉淀实验确定了Exo70形成二聚体的关键位置是位于氨基酸31~35与505~509的两段同样的序列SLEKS。进而利用这两个序列的缺失突变体,通过transwell迁移实验,证实这两段SLEKS序列在Exo70二聚化及乳腺癌细胞迁移过程中的关键作用。以上结果为Exo70独立于Exocyst复合体功能之外的新功能研究提供了依据,也为乳腺癌及其转移的治疗提供潜在的靶点。Exo70,the key subunit of Exocyst protein complex,promotes cell metastasisby self-dimerization or by involving in the Exocyst complex formation.In this research,we found that Exo70 was dramatically more capable of forming self-dimerization than binding to the other subunits of exocyst complex,and aindicative of the important roles of its self-dimerization.Then we constructed a set of truncation mutants of Exo70 in order to determine the core sequence for its dimerization.With co-immun oprecipitation analysis,we identified two identical protein sequences"SLEKS"located at amino acid 31~35 and 505~509 as critical sequencesfor the dimerization of Exo70.By "cell transwell"essay,we further found that the full length Exo70 significantly promotes breast cancer metastasis,while the two truncation mutants of Exo70(Δ31~35 and Δ505~509) don't process such ability,indicating that these two "SLEKS"sequences play pivotal role in breast cancer cell metastasis and invasion.Together,these results provide fundamental basis for researches on novel functions of Exo70 besides its well-known role in Exocyst complex formation and provide potential drug target for treating breast cancer and its metastasis.国家自然科学基金青年项目(31300970);; 福州大学科研启动项目(510402)共同资

芪参益气滴丸对ApoE基因敲除小鼠动脉粥样硬化中调节性T细胞的影响

目的:研究芪参益气滴丸对动脉粥样硬化中调节性T细胞的影响。方法:采用6周龄雄性C57BL/6J小鼠和Apo E基因敲除小鼠,分为正常组、模型组、芪参低剂量组、芪参高剂量组,每组6只。除正常组外,其他3组小鼠均给予高脂饲料喂养,药物组还给予高、低剂量的芪参益气滴丸,8周后评价内脏指数、动脉粥样硬化病变、调节性T细胞情况。结果:与模型组比较,芪参高剂量组可显著降低肝指数(P<0.05),减少动脉粥样硬化斑块面积(P<0.05,P<0.01),并增加脾脏调节性T细胞数量(P<0.01)。结论:芪参益气滴丸可能通过增加脾脏调节性T细胞数量抑制动脉粥样硬化形成。福建省自然科学基金项目(No.2016J01413);;广东省自然科学基金项目(No.2016A030313860);;教育部留学回国人员科研启动基金项目(No.2015-311);;教育部“新世纪优秀人才支持计划”项目(No.NCET-13-0505);;国家重点研发计划“重大慢性非传染性疾病防控研究”重点专项(No.2016YFC1305903)~

LTE基于QoS业务的比例公平调度算法研究

首先介绍目前无线通信中常用的3种调度算法。为了提高频谱利用率,通过仿真比较了3种常用调度算法对系统性能的影响,提出基于QoS（服务质量）业务的比例公平调度算法。该调度算法兼容了其他调度算法的优点。实验中对用户配置不同的QoS参数,从吞吐量的角度来验证不同配置的用户有不同的吞吐量,而且系统会优先保障最优用户的需求。该调度算法提高了系统的最大吞吐量,满足了用户调度的公平性,给用户提供了不同的业务服务,保障了用户的不同需求

Relationship Between Diaspore Traits and Inter-tidal Zonation of Non-viviparous Mangrove Species

利用分带值的方法调查了海南东寨港和清澜港的红树林群落结构组成状况,比较了4种非胎生红树植物(瓶花木、海漆、榄李和老鼠簕)的繁殖体散布特征(大小、质量和漂浮性)和萌发的初始时间和萌发率的情况.4种非胎生红树植物在潮间带的位置从海到陆依次是:瓶花木、海漆、榄李和老鼠簕.繁殖体的大小按长度依次是榄李>老鼠簕>瓶花木>海漆,按质量依次是老鼠簕>榄李>瓶花木>海漆.瓶花木和榄李有很好的漂浮性,其次是海漆,老鼠簕的漂浮性最差.榄李的种子具有休眠的特点,因此萌发实验用50 d湿处理对榄李进行解除休眠.盐度高于30时榄李不能萌发,而老鼠簕对盐度具有很好的耐受性,在30盐度以下,萌发率都很高,甚至达到了100%.4种非胎生红树植物繁殖体的散布特征和萌发情况,对于了解红树植物在潮间带的分带现象有重要意义.Sequencing scores of four non-viviparous mangrove species(Scyphiphora hydrophyllacea Gaertn.,Excoecaria agallocha L.,Lumnitzera racemosa(Jack.) Voigt.,and Acanthus ilicifolius L.) were obtained from mangrove communities in Dongzhai harbor and Qinglan harbor in Hainan.The differences in dispersal properties such as length,mass,buoyancy and germination of these four non-viviparous mangrove species were investigated.Distribution order of these species from low to high inter-tidal zones were S.hydrophyllacea,E.agallocha,L.racemosa,A.ilicifolius.The order of diaspore longevity was L.racemosa>A.ilicifolius>S.hydrophyllacea>E.agallocha,while diaspore masses were in the order of A.ilicifolius>L.racemosa>S.hydrophyllacea>E.agallocha.Among these four non-viviparous species,diaspore buoyancy was in the descending order of S.hydrophyllacea>L.racemosa>E.agallocha>A.ilicifolius.Due to seed dormancy of L.racemosa,the propagules for germination were stored in wet condition for 50 d.Propagules of L.racemosa failed to germinate at salinities over 30.Propagules of A.ilicifolius were more tolerant to high salinity than those of L.racemosa.It was even with 100% germination at salinities less than 30.Diaspore dispersal characters of these four non-viviparous species are important in understanding the phenomenon of mangrove zonation in inter-tidal zone.国家海洋局海洋公益性行业科研专项(200805072);国家海洋局908项目(908-02-04-04);教育部新世纪优秀人才计划资
