Evaluation of a lower-body compression garment

The aims of this study were to determine how custom-fit compression shorts affect athletic performance and to examine the mechanical properties of the shorts. Ten male and 10 female track athletes on a university's nationally competitive track team, specializing in sprint or jump events, participated in the study. Testing utilized the compression shorts with loose-fitting gym shorts as the control garment. Several significant effects were revealed for the custom-fit compressive garment. Although 60 m sprint time was not affected, hip flexion angle was reduced. Skin temperature increased more and at a faster rate during a warm-up protocol. Muscle oscillation was decreased during vertical jump landing. Countermovement vertical jump height increased when the participants were wearing the custom-fit compression garment. In materials testing, the elasticity of the compressive garment provides increased flexion and extension torque at the end range of extension and flexion, respectively, and may assist the hamstrings in controlling the leg at the end of the swing phase in sprinting. The compressive garment significantly reduced impact force by 27% compared with American football pants alone. Through various mechanisms, these findings may translate into an effect on athletic performance and a reduction in injuries.     

Spelling correction in the PubMed search engine

It is known that users of internet search engines often enter queries with misspellings in one or more search terms. Several web search engines make suggestions for correcting misspelled words, but the methods used are proprietary and unpublished to our knowledge. Here we describe the methodology we have developed to perform spelling correction for the PubMed search engine. Our approach is based on the noisy channel model for spelling correction and makes use of statistics harvested from user logs to estimate the probabilities of different types of edits that lead to misspellings. The unique problems encountered in correcting search engine queries are discussed and our solutions are outlined.     

社会主义市场经济条件下高校德育观的思考

在社会主义市场经济条件下，确立新的德育观改进和加强我国高校德育工作，从来没有显得象今天这样紧迫。所谓德育观，是指人们对德育的根本看法和动点。什么样的德育观，就反映出什么样的德育性质、巨的、任务，就反映出德育在学校教育中的地位和作用德育观作为一种思想观念．一方面决定于社会状况和经济基础，另一方面取决于德育本身在学校教育和人才培养过程中的意义和效果。作为自古以来就是学校教育内容之一的德育，它是指学校对学生进行思想品德教育。它的社会本质，是把反映生产关系的立场观点、思想意识、行为规范等社会意识形态传授…     

毛泽东的哲学思维及其领导艺术

毛泽东是一位与哲学结下不解之缘的杰出领导者,其高超的领导艺术得益于他博深的哲学思维。注重从哲学高度观察、分析和解决问题,注重将哲学应用于领导方法和工作方法中,注重适应新的需要创造哲学新理论,注重提高干部、群众的哲学素养,是毛泽东把哲学思维运用于领导工作的突出的最有特色的表现。     

经济报道的科学性与科学新闻的经济观

我们生活在一个以信息为主要特征的新经济时代,谁能最先最有说服力地引起人们的注意力,谁就可能占得先机,于是注意力就变成了商机！这就是“注意力经济”的典型特征。同时我们又生活在科学技术推动的文明时代,在到国家决策,小到日用品、家用电器,科学技术无所不在。我们还生活在一个科技和经济一体化的新时     

Co-expression of sCD40LIg and CTLA4Ig mediated by adenovirus prolonged mouse skin allograft survival

INTRODUCTION Costimulatory signals play a vital role in T cell activation. B7/CD28 and CD40/CD40L have been well-established as important costimulatory pathways, with the blockade of either resulting in suppression or anergy of T cells associated with prolongation of graft survival (Akalin et al., 1996; Bolling et al., 1996; Kita et al., 1999; Reddy et al., 2001; Laumonier et al., 2003; Thiel et al., 2005). Cytotoxic T lymphocyte associated antigen-4 (CTLA4), a ligand for B7, de-…
