Bioinformatics Assisted Gene Discovery and Annotation of Human Genome

IntroductionBioinformatics is coming with Human GenomeProject(HGP) . With the explosions of sequence,structural and other information available ,bioinformatics is playing an increasingly large rolein the study of fundamental biomedical problems.At present and in the near future,it is the mainchallenge for bioinformatists to make gene dicoveryand annotation of human genome sequences whenthe vast amount of data is produced by the highthroughput genome sequencing in a large scale andautomated m…     

A New Organo-templated Layered Zincophosphate Synthesized from a Solvothermal System Containing Racemic1,2-Diaminopropane

IntroductionSince Wilson and co- workers successfullysynthesized three- dimensional microporousaluminophosphates (Al PO4 - n ) [1] in the 1 980 s,much attention has been focused on the explorationof1 - D chain,2 - D layer and3 - D open- frameworkmetal phosphates from aqueous or non- aqueoussystems.The number of metals incorporated intothe frameworks of these materials is continuouslyincreasing and the metals include Be[2 ] ,Ga[3] ,In[4 ] ,Sn[5] ,Sb[6 ] ,and the transition metals Zn[7] ,Ni…     

Effects of the Specific Area and the Thermal Stability of a Polymer on the Catalytic Activities of Polymer Immobilized Co-Pd Catalysts by SAMI

Co-Pd bimetallic catalysts immobilized with four kinds of resins with different specific areas were prepared by means of the solvated metal atom impregnation (SMAI) method. The results of the XRD and the magnetic measurement showed that as the specific area of the resin increased, the particle sizes of Co and Pd on the catalysts with the same metal content decreased, so the catalytic activity of the catalysts for the hydrogenation of diacetone alcohol as well as the reduction of oxygen on the fuel cell electrode increased. Below 140 , the conversion of diacetone alcohol increased as the reaction temperature increased, and above 140 , the conversion decreased because of the rupture of the resin.

The Elastic Continuum Limit of the Tight Binding Model

The authors consider the simplest quantum mechanics model of solids,the tight binding model,and prove that in the continuum limit,the energy of tight binding model converges to that of the continuum elasticity model obtained using Cauchy-Born rule.The technique in this paper is based mainly on spectral perturbation theory for large matrices.     

用于氢过氧自由基光谱和动力学分析的腔衰荡光谱装置

基于近红外腔衰荡光谱技术(CRDS)结合闪光光解，搭建了一套用于瞬态自由基探测的高灵敏度实验装置。通过扫描自主设计的光学谐振腔腔长，实现激光器与腔的模式耦合，基于线性回归求和(LRS)算法对衰荡曲线进行拟合，获得衰荡时间，在20.3 km有效光程和6.25 s采集时间下，系统可实现5.05×10–11cm^–1的探测灵敏度。使用266 nm Nd:YAG激光器光解臭氧(O₃)和乙炔(C₂H₂)的混合物产生氢过氧自由基(HO₂·)，测量了HO₂·在6638.203 cm^–1位置处的特征吸收，获得了分辨率为0.002 cm^–1的吸收光谱。在2 kPa条件下，通过测量HO₂·自反应的衰变获得了6638.203 cm^–1处HO₂·的吸收截面(σ)为3.3×10^–19cm²/molecule，对应的吸收谱线强度(S)...
