| 1 | Experimental study on dynamic load magnification factor for ballastless track-subgrade of high-speed railway显示文摘The magnitude of dynamic load produced by high-speed trains depends on many factors,of which train speed is the most critical one.However,it is quite difficult to determine the effect of train speed on dynamic load using the theoretical methods due to the complexity of the interaction between vehicle and track-subgrade.Thus large-scale model test has gradually become an important approach for studying dynamic responses of ballastless track-subgrade of high-speed railway.In this study,a full-scale model of ballastless track-subgrade was constructed in accordance with the design and construction standards for Shanghai-Nanjing intercity high-speed railway line firstly.Then,the dynamic strain of slab and the dynamic earth pressure of subgrade were measured by conducting single wheel axle excitation test.In addition,the relationship between the dynamic load magnification factor(DLF) and the train speed was obtained.Finally,the DLF of track-subgrade under different train speeds was proposed,similar to that given by German Railway Standard. | Renpeng Chen Xing Zhao Zuozhou Wang Hongguang Jiang Xuecheng Bian | 2013 | Journal of Rock Mechanics and Geotechnical Engineering2013，5，4： | 5 |

| 3 | A gene family-based method for interspecies comparisons of sequencing-based transcriptomes and its use in environmental adaptation analysis显示文摘We describe a new method for sequencing-based cross-species transcriptome comparisons and define a new metric for evaluating gene expression across species using protein-coding families as units of comparison.Using this measure transcriptomes from different species were evaluated by mapping them to gene families and integrating the mapping results with expression data.Statistical tests were applied to the transcriptome evaluation results to identify differentially expressed families.A Perl program named Pro-Diff was compiled to im-plement this method.To evaluate the method and provide an example of its use,two liver EST transcriptomes from two closely related fish that live in different temperature zones were compared.One EST library was from a recent sequencing project of Dissosticus maw-soni,a fish that lives in cold Antarctic sea waters,while the other was newly sequenced data(available at:http://gffzzc5668baaf8224a60hx5kuqwo60xwo6qxu.ffgz.tsg.suse.edu.cn/polarbank/) from Notothenia angustata,a species that lives in temperate near-shore water of southern New Zealand.Results from the comparison were consistent with results inferred from phenotype differences and also with our previously published Gene Ontology-based method.The Pro-Diff program and operation manual can be downloaded from:http://gffzzc5668baaf8224a60hx5kuqwo60xwo6qxu.ffgz.tsg.suse.edu.cn/download/Prodiff.rar. | Zuozhou Chen Hua Ye Longhai Zhou Chi-Hing C.
