猪型布鲁氏菌Omp31抗原表位基因的性质分析

布鲁氏菌病是一种由革兰氏阴性小杆菌:布鲁氏菌(Brucella)引起的,主要在动物中以流产和发热为表现特征的疾病.以猪型布鲁氏菌病Omp31抗原表位基因作为研究对象,对基因的种间同源性、亚型分类、结构性质、抗原表位性质等信息进行了分析,并且作出了相关预测.随着预测方法的不断完善,将会对布鲁氏菌病其它抗原表位基因的研究提供帮助,从而为该疾病的防疫、治疗提供理论依据,同时也可以促进相关疫苗的研制.

Parallelization and Performance Optimization on Face Detection Algorithm with OpenCL: A Case Study

Face detect application has a real time need in nature. Although Viola-Jones algorithm can handle it elegantly, today’s bigger and bigger high quality images and videos still bring in the new challenge of real time needs. It is a good idea to parallel the Viola-Jones algorithm with OpenCL to achieve high performance across both AMD and NVidia GPU platforms without bringing up new algorithms. This paper presents the bottleneck of this application and discusses how to optimize the face detection step by step from a very nave implementation. Some brilliant tricks and methods like CPU execution time hidden, stubbles usage of local memory as high speed scratchpad and manual cache, and variable granularity were used to improve the performance. Those technologies result in 4-13 times speedup varying with the image size. Furthermore, those ideas may throw on some light on the way to parallel applications efficiently with OpenCL. Taking face detection as an example, this paper also summarizes some universal advice on how to optimize OpenCL program, trying to help other applications do better on GPU.

Identification of AtSM34, a novel tonoplast intrinsic protein-interacting polypeptide expressed in response to osmotic stress in germinating seedlings

Aquaporins are implicated in a wide variety of plant physiological processes, although the mechanisms involved in their regulation are not fully understood. To gain further insight into the regulatory factors involved in this process, we used a yeast two-hybrid system to screen for potential binding partners to the Arabidopsis tonoplast intrinsic protein (TIP) AtTIP1;1. This was the first protein identified to be associated with high water permeability in vacuolar membranes from Arabidopsis thaliana. Using ...     

热预处理对细胞分裂效率的影响

以发酵酵母为研究对象，采用超声波空蚀和高压均质方法对细胞进行机械细胞分裂，研究了热预处理对微生物细胞分裂效率的作用。结果表明：酵母悬浮液的温度经热预处理从室温（22±1）℃上升到40-50℃时，达到相同程度的细胞分裂效率所需的能量降低了；当酵母悬浮液的温度经热预处理上升到50℃时，蛋白质浓度达到最大值，蛋白质发生变质的热预处理温度≥52℃。     

回归大传统：中国文明起源特性与神话学整合

文章立足中国本土文化的渊源与核心去探讨中国文化的＂大传统＂问题。首先从中国文明起源特性及影响,即从生产工具、血缘与地缘关系、城市的出现与功能等三方面论述了中国文明起源特点,及由此形成的中国文化特点：表现为最浓厚的＂信仰—仪式＂统一体和稳定共同体特色,具有连续性和整体性。而西方文明的发生是突破性的,社会科学里面那些从西方经验而来的一般法则不能有普遍的应用性。针对此,文章进一步论述了目前的中国考古学和神话学都没有充分发挥其学科优势来做相关研究。如何尽量回到上古文化语境去阐释出土器物,回归中国文化大传统———这成为中国考古学与神话学势必结合的理论根基和整合视野所在。     

Preparation and kinetic analysis of Li4SiO4 sorbents with different silicon sources for high temperature CO2 capture

Using diatomite and analytical pure SiO2 as silicon sources,Li4SiO4 sorbents for high temperature CO2 capture were prepared through solid-state reaction method.Phase composition was analyzed by X-ray diffraction,and the CO2 absorption capacity and absorptoin-desorption performance were studied by the simultaneous thermal thermogravimetric analyzer(TG-DSC).The results showed that silicon source had an important influence on CO2 absorption properties.The kinetic parameters for the chemisorption and diffusion processes were obtained by the isothermal study for different silicon sources.The results showed that the activation energies for these two processes were estimated to be 105.427 and 35.928 kJ/mol for the sample with analytical pure SiO2(AS).While for the sample with diatomite(DS),the activation energies for these two processes were estimated to be 78.500 and 20.439 kJ/mol,respectively.
