Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Review on Endogenous Information Security Technology of Industrial Measurement and Control Equipment
, 2022 工业测控设备是工业控制系统的神经中枢，其信息安全问题直接关系到工业控制系统的安全。传统信息安全防护技术手段具有局限性，网络无法阻断物理介质传输数据和物理设备的接入，即使是物理隔离的工业测控设备，亦可以成为攻击目标，迫切需要增强工业测控设备自身的内生安全防护能力。本文结合相关国际标准和国家标准，将工业测控设备内生信息安全防护技术分为静态加固技术和动态防护技术，对涉及的七类信息安全防护技术进行了逻辑分类，给出了工业测控设备的内生信息安全的术语定义，并具体分析、评价了已有相关理论研究和关键技术的优势和不足之处。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.
