Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

东北虎（Panthera tigris altaica）个体识别技术研究进展
野生动物学报, 2013 对东北虎种群的科学监测是采取有效保护、管理及恢复措施的基础,而准确的个体识别又是保证有效监测的前提。尤其是在中国,在野生东北虎种群数量很少,种群密度极低的情况下,能根据它留下的各种信息进行个体识别就显得尤为重要。目前,用于野生东北虎个体识别的技术主要有:足迹识别、DNA识别、条纹识别以及气味识别等。本文对这几种技术的特点、研究进展、应用注意事项等做了介绍,并且结合中国的实际情况,分析每种技术在中国的适用性,认为如果要建立中国的东北虎种群数量数据库 ...

The Research and Application of the Investigation and Comparison of Face Recognition System [PDF]
, 2015 在最开始，人脸检测识别技术是在数字信息自动识别人脸的系统中的定位环节被提出的，由于该技术具有广泛的应用领域，使其理论研究价值日渐重要。近年来，在模式识别、图象处理、人工智能化等领域，该技术扮演了重要角色。 与人体其他的生物特征——DNA、虹膜、指纹等相比，人脸特征多个优点，包括自然性、非接触性、唯一性等，使用生物个体的脸部器官、肤色等方法进行身份验证识别被多数人所接受。人脸识别的目的在于用计算机自动处理某些信息系统，以代替人去完成分类及系统辨识的任务。模式识别是人脸识别的重要理论基础和环节 ...

The Role of Technology Standards in Strategic Hedging
Asian Politics &Policy, Volume 18, Issue 2, April 2026.ABSTRACT This article argues that technology standards provide Southeast Asian states with a distinct mechanism for hedging amid intensifying US–China technological rivalry. Traditional hedging strategies emphasizing economic engagement without political alignment are increasingly constrained by the weaponization of technological interdependence ...
