Identification of susceptibility genes loci associated with type 2 diabetes

In this study, we selected 10 susceptible SNPs loci to investigate their contribution to susceptibility to type 2 diabetes in Han Chinese among Hubei population. We genotyped SNPs rs5219, rs1801282, rs1470579, rs1111875, rs1081661, rs7754840, rs4506565, rs13266634, rs4402960, and rs5643981 by using the method of polymerase chain reaction-ligase detection reaction (PCR-LDR). In a case-control study, we have genotyped the 10 candidate susceptibility SNP loci, and here, we reported that the SNP rs5219 in KCNJ1...

微合金非调质40Mn2V钢管的变形抗力研究

采用Gleeble-1500 热模拟实验机对微合金非调质40Mn2V钢管的变形抗力进行了研究.结果表明,变形温度越高,变形速率越低,钢管变形抗力越小.变形抗力对数值lnσ随着温度升高和变形速率对数值lnε·的增大,分别呈线性减小和线性增大,且变形抗力与变形程度呈非线性关系.采用Matlab软件拟合出了微合金非调质40Mn2V钢管的变形抗力公式,其拟合度R为0.966 3.     

析当前我国大学生失业的特点

大学生失业从历史和世界的角度来考察,是一种比较普遍的社会现象。1999年高校扩招之后,我国开始出现了比较突出的大学生失业现象,并引起了人们的高度关注。当前我国大学生的失业现象具有必然性和合理性、主动性和被动性、相对性、差异性等特点,分析这些特点有助于我们全面地辩证地认识大学生失业现象。     

Medical entity and attributes extraction system based on relation annotation

The abundant entities and entity-attribute relations in medical websites are important data resources for medical research. However, the medical websites are usually characterized of storing entity and attribute values in different pages. To extract those data records efficiently, we propose an automatic extraction system which is related to entity and attribute relations (attributes and values) of separate storage. Our system includes following modules: (1) rich-information interactive annotation page rendering; (2) separate storage attribute relations annotating; (3) annotated relations for pattern generating and data records extracting. This paper presents the relations about the attributes which are stored in many pages by effective annotation, then generates rules for data records extraction. The experiments show that the system can not only complete attribute relations of separate storage extraction, but also be compatible with regular relation extraction, while maintaining high accuracy.     

重新解读网络环境下的文件生命周期理论

文件连续体理论与文件生命周期理论之争,其主因是档案学界对两种理论定位和电子文件生命周期的认识不一.本文对此从一切文件皆有生命周期、电子文件生命周期表现形式与纸质文件生命周期表现形式比较、科学认识网络环境下的文件生命周期理论三方面,运用辩证唯物史观重新解读网络环境下的文件生命周期理论.     

A bioinformatic evaluation of potential allergenicity of 85 candidate genes in transgenic organisms

The potential of genetically modified organisms(GMOs) to increase allergenicity or predispositions to allergies has attracted much attention.An approach that will properly and holistically evaluate the allergenicity of GMOs is yet to be found.Here,85 transgenes that have been reported in both international and domestic studies during recent years are summarized case by case;49 of the transformed genes were from plant sources and 36 were from animal sources.EVALLERTM,a web server for the in silico assessment of potential protein allergenicity,was used to evaluate the potential of the transgenic proteins as allergens.The biomedical journals listed in Highwire(http://highwire.stanford.edu/) were searched and reviewed to decipher whether any of the transformed genes were linked to allergenicity or human health.The EVALLER analysis identified 5 allergenic genes,whilst our literature review found 11 genes that were either related to allergic cases or to clinical adverse events;all 16 of these genes have been used in GMOs.The analysis pathway that we have developed can help guide the selection of genes to be used in genetic modification.The pathway also provides a paradigm for allergenicity analysis of transgene candidates.     

短波跳频FH/QDPSK系统信道自适应监测的研究(Ⅱ)

基于短波跳频FH/QDPSK系统的FFT解调，利用FFT解调的结果，提出了在瑞利衰落信道中对信道的BER进行实时自适应监测方法，该方法利用伪错监测及其非线性外推较好地解决了在较短的监测时间内获得较为精确的监测结果。模拟结果表明，采用伪错的非线性外推算法，其估值的最大绝对误差不超过0.28，最大相对误差不超过12.1%。
