Many studies have demonstrated the linkage between the IBD3 region (6p21.1-23), an area which encompasses the famous human leukocyte antigen (HLA) complex, and Crohn’s disease (CD) or ulcerative colitis (UC). IBD3 is the only region that meets genome-wide significance, and provides stronger evidence of the linkage than 16p13.1-16q12.2 (IBD1), the locus that contains the susceptibility gene CARD15. However, despite these findings, IBD3 susceptibility genes remain elusive and unclear due to the strong linkage disequilibrium, extensive polymorphism, and high gene density that characterize this area and also due to varying allele frequencies in populations around the world. This area presents an extremely high abundance of genes, including the classical and non-classical major histocompatibility complex (MHC) class I and II genes, and other genes, namely MHC class III genes tumor necrosis factor (TNF)-α and -β, and Hsp, whose proteins play key functions in immunological processes. To date, it is not clear which genes within the MHC family contribute to the IBD pathogenesis, although certain HLA alleles have been associated with IBD. Recent insights into the biological function of other genes encoded within the IBD3 region, such as the MHC class I chain-related (MIC) genes, have led investigators to a more comprehensive exploration of this region. MHC class I chain-related molecule A (MICA) is highly polymorphic and interacts with NKG2D, its receptor on the surface of NK, Tγδ and T CD8+ cells. Increased expression of MICA in intestinal epithelial cells and increased expression of NKG2D in CD4+ T cells (lamina propria) in patients with CD have also been reported. MICA alleles have also been associated with IBD, and a variation at amino acid position 129 of the α2-heavy chain domain seems to categorize MICA alleles into strong and weak binders of NKG2D rece

Protein evolution proceeds by two distinct processes： 1） individual mutation and selection for adaptive mutations and 2） rearrangement of entire domains within proteins into novel combinations, producing new protein families that combine functional properties in ways that previously did not exist. Domain rearrangement poses a challenge to sequence alignment-based search methods, such as BLAST, in predicting homology since the methodology implicitly assumes that related proteins primarily differ from each other by individual mutations. Moreover, there is ample evidence that the evolutionary process has used （and continues to use） domains as building blocks, therefore, it seems fit to utilize computational, domain-based methods to reconstruct that process. A challenge and opportunity for computational biology is how to use knowledge of evolutionary domain recombination to characterize families of proteins whose evolutionary history includes such recombination, to discover novel proteins, and to infer protein-protein interactions. In this paper we review techniques and databases that exploit our growing knowledge of “horizontal” protein evolution, and suggest possible areas of future development. We illustrate the power of the domain-based methods and the possible directions of future development by a case history in progress aiming at facilitating a particular approach to understanding microbial pathogenicity.

数学课堂中的交流直接影响着教师对于数学概念的传达与学生的数学学业表现。数学教学中的课堂交流在最近的中学数学研究中成为热点。在肯尼亚,大多数中学的数学学业表现都不佳,缺乏有效的课堂交流被认为是影响学生数学学业表现的一个重要因素。因此,本研究以肯尼亚马查科斯地区为例,探究了中学数学教学过程中的课堂交流问题。具体地说,探究了教师相关和学生相关的影响课堂交流的一系列因素,目前数学课堂中流行的交流模式,以及数学课堂交流面临的挑战。本研究的理论框架改编自Bamlund (2008)的交流转化模式。本研究主要采用调查法,主要是的数据收集工具是问卷,辅之以访谈。本研究包括来自东肯尼亚马查斯克地区的8所公立中学的43位数学教师和143名学生。量化的数据通过问卷收集并进行了描述性分析;质化的数据通过发掘讨论中的重要主题进行了主题研究。量化和质化的研究结果都显示,绝大部分的教师和学生对于数学课堂上的交流有着积极的态度,并且能够在日常生活中较熟练的掌握使用数学语言和数学应用。并且,教师自身的数学背景,在教学过程中的清晰度,以及数学教师对于数学教学的兴趣,并未对他们的数学教学带来太多影响。这些积极的属性都对于数学课堂上的有效交流做出贡献。然而,当下大多数样本学校中最常用的数学课堂交流模式是贡献的交流模式。开放式问题的使用和小组讨论的方式被发现在大多数数学课堂中还十分缺失。同时,低水平的师生交互作用,缺乏教学资源,学生的缺席和大班额,也被认为是数学课堂交流面临的主要挑战。这些因素也可能正是造成数学课堂师生交流无效的原因。为了促进有效的课堂交流和帮助学生更好的理解数学概念,本研究建议教师在数学课堂交流中平衡关注点(关注自己,关注任务,与关注效果),并经常使用开放式问题和小组讨论的方法。与此同时,教育部门,学校教育管理者和相关教育权威应该致力于解决师生比,教学资源与确保数学教师专业发展、提高教师专业能力与教学技能。这些措施都能促进有效的数学课堂交流。

非洲移动电话使用的快速增长及其发明份额促进了移动货币的发展。在非洲,30%的人口被排除在传统银行系统之外,因此移动货币可以规避这一问题,同时完美地满足无法使用正规金融结构的某些类别人口的需求,例如银行。这些服务非常受欢迎,甚至那些拥有银行账户的人也会使用它们。因此,我们的思考围绕以下核心问题展开:“贝宁采用移动货币是否符合节约型创新(可负担性、可用性、可接受性、知名度)?”。为了更好地解决这个问题,我们将首先展示移动货币的创新性和节俭性,然后展示这种创新如何有助于改善贝宁欠发达地区人口的购买条件和增加交流。因此,我们研究的目的是强调我们可以阐明节约型创新在贝宁,尤其是在这些欠发达地区成为现实的要素。该研究的独特之处在于,它是为数不多的为不稳定地区的社区开展移动货币和节约型创新合作研究的研究之一。研究的最初目标导致了一些研究问题的产生,这些问题可以确认或不确认研究的目的。核心问题如下:在贝宁已经成为现实的移动货币的采用是否符合节约型创新的标准(负担能力、可用性、可接受性、知名度)?这个中心问题被细分为其他几个具体问题如下:贝宁未开发地区的居民是否可以使用移动货币服务?贝宁欠发达地区的人们是否负担得起移动货币服务?贝宁欠发达地区的人们是否可以轻松获得移动货币?移动运营商的宣传渠道是否有效地鼓励贝宁非建成区的居民采用移动货币?回答这些问题需要明确的假设才能开展良好的研究。该假设是对所提问题的建议答案,我们在整个研究过程中分析和测试了以下各种假设:假设1:移动货币的可用性促进了贝宁未建地区人口对移动货币的采用;假设2:移动货币的可负担性解释了它在贝宁欠发达地区的人口采用;假设3:移动货币系统的可及性改善了贝宁欠发达地区人口的购买条件;假设4:提高移动运营商意识的手段促进了贝宁非建成区人口采用移动货币的动机。一旦制定了研究的各种假设,就会进行文献综述,其中汇集了关于我们主题的文献中存在的所有内容,即:我们研究的各种关键概念的一些定义,以及关于什么是创新的信息,什么是节俭,然后是节俭创新本身。节约型创新在欠发达地区的重要性,节约型创新理念在非洲开展的一些例子,节约型创新与移动货币之间的关系,移动货币在非洲的采用情况即其运营和发展,移动货币的主要优势和问题,移动货币和人口普惠金融等。为了了解更多关于这个概念的信息,我们提供了一个全面的实证文献回顾和我们之前陈述的目标。然后提出了该研究的概念模型来解释我们研究的不同变量之间的联系。本研究采用的主要研究方法是定量方法。它使我们能够在5分李克特量表上进行主题分析和问卷调查,最终对149名符合研究人口统计要求的参与者进行了调查。使用调查技术向受访者传播结构化问题。为了便于数据分析,调查分为三个关键部分,第一部分涵盖受访者的社会人口统计描述,第二部分涵盖我们的自变量,包括可用性、可负担性、可及性和知名度等问题,而最后一部分是专门讨论我们的因变量,以及与使用移动货币给他们带来的“加分”相关的问题。然后,借助IBM SPSS统计数据处理软件,在问卷收集的信息基础上,对受访者进行社会人口学分析、变量的描述性分析、信度检验、相关检验和多元回归检验可以执行。描述性分析是将数据转化为信息的过程。测试信度是指测试在测量其预期测量内容时的一致性和稳定性的程度。Pearson相关系数,也称为r系数,是一种统计量度,用于定义两个变量之间的关系强度及其相互关联,多元回归的总体目标是了解几个独立变量之间的关系或预测变量和因变量或标准变量。总而言之,该研究的概念框架使我们能够确认研究结构与我们各种分析的结果之间的联系,使我们能够测试和验证我们的每一个假设。关于参与调查者的社会人口统计分析,年龄和性别交叉表显示26-35岁年龄组的人数较多,这一发现在男性和女性中均有体现。因此,我们的数据库主要由或多或少的年轻人组成;至于居住城市和职业的交叉表,我们注意到从事公务员职业的受访者最多,居住在贝宁经济首都科托努市的受访者最多统计数据显着;该分析以银行账户和移动货币账户的交叉制表结束,从中我们注意到移动支付的使用比银行账户的使用更普遍。信度检验的结果如下,我们可以看到项目之间的相关性都是正相关且可靠的,因为它们是由大于0.7的Cronbach's alpha确保的。因此,这些结果表明,移动货币服务消费者提供的响应之间存在内部一致性。接下来要进行的测试是相关性分析测试,其结果表明存在正相关但弱相关。移动货币的采用随着其可用性、成本、可访问性和移动运营商的意识水平而增加,即使影响很小。由于默认的alpha值为0.05,我们的相关性被认为非常显着。根据多元回归分析表的结果,该模型约占移动货币采用(因变量)整体变化的53.8%,如独立因素所解释的那样。因此,该结果向我们展示了独立因素对因变量影响的大小和重要性。根据同一张表中的结果,

In this paper, the authors explore the potential of several popular equalization techniques while overcoming their disadvantages. First, extensive literature survey on equalization is conducted. The focus is on popular linear equalization algorithms such as the conventional least mean square (LMS ) algorithm, the recursive least squares ( RLS ) algorithm, the filtered X LMS algorithm and their development. To overcome the slow convergence problem while keeping the simplicity of the LMS based algorithms, an H 2 optimal initialization is proposed.
