Simi视频动作捕捉系统在步态识别中的应用

目的探讨人体行走运动主要步态特征参数新的提取识别方法和定量化分析技术。方法以步态分析技术与传统的足迹检验理论和方法为基础,运用先进的Simi Motion视频动作捕捉系统,对50名健康男性正常行走的步态特征参数进行识别和分析。结果提出了一种基于关节点的步态特征提取方法,得到了行走步态特征的基本参数,为步态特征定量化检验提供技术支持。结论研究表明,simi视频动作捕捉系统可以获得较精确的步态特征数据,能够满足人体步态分析的需求,进而达到人身个体识别的目的。     

群体性纠纷解决机制之辨析

群体性纠纷事件频发,而代表人诉讼制度却被各种司法解释限制了适用,实际上已被束之高阁.集团诉讼、团体诉讼制度虽然在解决群体性纠纷方面具有巨大的优越性,但是在我国“司法无力”的困境下,盲目移植必定水土不服.法之理在法内,更在法外,法律制度的构建必须考虑社会现实,示范诉讼在传统“一对一”诉讼结构下解决群体性纠纷的优势得以凸显.     

探析毕节模式对中国多党合作的价值和意义

毕节试验区成立20多年来,一种成功的模式--毕节模式正呈现在我们面前.毕节模式成功的价值和意义,关键在于它为中国共产党领导的多党合作开辟了新思路,为中国参政党参与国家发展战略提供了现实舞台,充分彰显了中国多党合作的政治优势,丰富了新时期中国多党合作的内容.毕节模式是中国多党合作最集中、最突出的体现,是各民主党派履行参政...

自贸区与政治一体化——中日韩自贸区的战略设计及实施

中日韩第四次首脑峰会使东北亚自贸区的建设提上了日程,但是敏感而复杂的政治安全形势对自贸区的发展构成了现实的挑战。基于功能主义的现有地区合作框架并不能解决该地区深化发展所要面对的问题,中日韩三国需要构建一种基于相互承认逻辑的新地区发展战略。     

Say cheese! Privacy and facial recognition

The popular social networking site, Facebook, recently launched a facial recognition tool to help users tag photographs they uploaded to Facebook. This generated significant controversy, arising as much as anything, from the company’s failure to adequately inform users of this new service and to explain how the technology works.The incident illustrates the sensitivity of facial recognition technology and the potential conflict with data privacy laws. However, facial recognition has been around for some time and is used by businesses and public organisations for a variety of purposes – primarily in relation to law enforcement, border control, photo editing and social networking. There are also indications that the technology could be used by commercial entities for marketing purposes in the future.This article considers the technology, its practical applications and the manner in which European data protection laws regulate its use. In particular, how much control should we have over our own image? What uses of this technology are, and are not, acceptable? Ultimately, does European data protection law provide an adequate framework for this technology? Is it a framework which protects the privacy of individuals without unduly constraining the development of innovative and beneficial applications and business models?     

鸡源致病性沙门氏菌新近分离株的耐药性与耐药基因

为了了解河南省鸡源沙门氏菌新近分离株的药物敏感性和耐药基因的存在情况,为进一步研究细菌耐药的分子机制和新型抗菌药物的研制提供资料,利用K-B法检测了98株鸡源沙门氏菌对22种药物的敏感性,采用PCR方法检测了13种常见耐药基因在分离株中的分布情况。结果显示,所有菌株对红霉素、青霉素、阿齐霉素和氨苄西林的耐药率均在60%～100%之间。三重以上耐药的菌株高达96.94%,七重以上耐药的菌株为56.12%,耐药最多的菌株可耐受18种抗生素。从13种常见耐药基因中扩增到3种四环素类、2种氨基糖苷类、2种β-内酰胺类、1种氯霉素类和3种磺胺类耐药基因。研究表明,沙门氏菌极易产生耐药性,耐药基因广泛存在于耐药菌株中,但耐药表型与耐药基因之间无绝对相关性。     

Microcrystal analysis of cocaine hydrochloride and added adulterants

The objective of this project was to investigate the trends of changes in the crystal morphology of cocaine in the presence of the common adulterants, caffeine and lidocaine HCl. By performing gold chloride microcrystal tests on samples of cocaine with adulterants at 10, 20, and 50% concentrations, trends in the changes of the crystal morphology can be linked to specific adulterants and concentrations. For cocaine/caffeine mixtures, the trend is elongation of one axis, additional branching, and brown discoloration of the crystals. At 50:50 cocaine/caffeine mixtures, branched spherical crystals and long needles appear. The trends for cocaine/lidocaine mixtures include elongation of one axis with an X-shaped middle axis. The axes continue to grow and branching decreases until at 50%, spherical clusters of needles appear. These results indicate microcrystal analysis can be used as a novel method for presumptively identifying not only cocaine but also the identity and concentration of the adulterant.     

表观遗传学在法医学应用探讨

表观遗传学指没有DNA序列变化的、可遗传的基因表达改变。主要包括DNA甲基化、X染色体剂量补偿、组蛋白修饰、基因组印记、表观基因组学和人类表观基因组计划等方面的内容。在法医实际检案中常遇到一些特殊问题,如妊娠期胎儿父权的认定,单亲鉴定中亲代必需等位基因的确定,同卵双生子的区分,微量组织来源的鉴定等。本文对表观遗传学的基本内容和在法医学中的应用进行综述,以期为相关研究及实践提供参考。
