抖落铅华见精神——宗白华《流云》小诗与中国古典诗歌传统

宗白华是一位学贯中西的美学大家 ,但他首先是一位艺匠独运的现代诗人。其唯一诗集《流云》,虽是新体诗 ,却同中国古典诗歌一系根须。他承继古典诗歌传统而创作的现代诗歌 ,表现出对审美感兴、语言艺术、美学意境、诗人人格的全面扬弃 ,从而演绎出了一条千古一脉的诗歌。诗人生命的心路旅程 ,最终化为“对生命活力的倾慕赞美 ,对宇宙人生的哲理情思     

Active regions’ setting of the extracellular ligandbinding domain of human interleukin-6 receptor

The reliable three dimensional (3-D) structure of the extracellular ligand-binding domain (V106-P322) of human interleukin-6 receptor (hIL-6R) has been constructed by means of computer-guided homology modeling techniques using the crystal structure of the extracellular ligand-binding region (K52–L251) of human growth hormone receptor (hGHR) as templet. The space location of some key residues which influence the combination ability between the receptor and the ligand has been observed and the effects of point mutagenesis of the four conservative cysteine residues on the space conformation are analyzed. The results show that the space conformation of the side-chain carboxyl of E305 plays a key role in the ligand-binding ability. Furthermore, the space conformation of the side-chain carboxyl of E305 is very important for the electrostatic potential complementarity between hIL-6R and hIL-6 according to the docking method.     

鲁迅小说《伤逝》的文本建构策略

现代爱情小说的经典之作《伤逝》,自发表来一直为人们关注,也获得了高度评价。可是相关的评论文章多停留于宏大话语和文本"外部"问题的探讨上,很少从细部去阐述鲁迅作为"伟大文学家"之所在。潜心细读《伤逝》,它那玄妙精巧的双层标题、独特精深的单句开头、显隐交织的"手记"体叙事视角、意蕴丰赡的开放式结尾呈现了经典文本的建构策略——以现代叙事解构传统,彰显了鲁迅先生作为现代小说奠基人精湛的叙事技巧,也见证了他不愧为文学大师的美誉。

Identification of asymmetric prediction intervals through causal forces

When causal forces are specified, the expected direction of the trend can be compared with the trend based on extrapolation. Series in which the expected trend conflicts with the extrapolated trend are called contrary series. We hypothesized that contrary series would have asymmetric forecast errors, with larger errors in the direction of the expected trend. Using annual series that contained minimal information about causality, we examined 671 contrary forecasts. As expected, most (81%) of the errors were in the direction of the causal forces. Also as expected, the asymmetries were more likely for longer forecast horizons; for six‐year‐ahead forecasts, 89% of the forecasts were in the expected direction. The asymmetries were often substantial. Contrary series should be flagged and treated separately when prediction intervals are estimated, perhaps by shifting the interval in the direction of the causal forces.

3BP2中SH2结构域的晶体结构及其与来源于FRS2α的肽的复合物

提出了一个3BP2的Src同源区2结构域(SH2)不同于其他SH2结构域的全新肽链结合模式,它与FRS2来源的多肽结合于不同的氨基酸残基. 实际上,该SH2结构域与该短肽的三个重要残基相结合形成完美的几何互补,通过BioCore实验验证,这三个氨基酸最好是Y-E-N.     

日本科学家研究科技哲学经典著作述评

对日本著名科学家如何注重科技哲学经典著作的研究进行了评述，指出：他们对恩格斯的《自然辩证法》出版了多种译本，重视联系现代科学发展的实际，探讨其精神实质，纷纷发表自己的学习体会，并在此基础上，运用科技哲学经典著作的思想，分析了科技哲学的一些基本理论问题，提出了许多独到见解，为我国科技哲学研究提供了有益的启示。     

关于板的Reissner理论和Mindlin理论的某些评注<英>

英汉古典诗格律比较

诗是最凝练、最富有表现力的艺术形式,是语言的精华,诗的格律是由无数诗人的长期创作实践而形成的一套诗创作声律方面的格式和规则。格律的各种要素,使人们在听觉上,视觉上和意念上对诗歌产生综合的美感。平仄及音步的程式能使诗产生抑扬之美,用韵规则可使诗具有回环之美。     

多体系统的时域和频域分析

介绍多体系统的概念及其动力学特性。在时间域和频率域进行了理论分析,开发了一般多体系统动力学分析程序DAGOMS及其FTT后续处理程序PTODA。以工业机器人为典型系统进行了实验模态分析,识别了接合面物理参数。用上述程序进行计算,求得时域和频域数值解。理论分析与实验结果吻合较好。
