Evaluating cryptographic vulnerabilities created by quantum computing in industrial control systems
Journal of Critical Infrastructure Policy, Volume 5, Issue 2, Page 88-110, Fall/Winter 2024.Abstract Quantum computing is expected to eventually be able to break the public‐key cryptography algorithms currently used throughout information technology (IT) infrastructure, undermining foundational tools used to maintain information security across the country's critical infrastructure.

Gaoya dianqi, 2012 笔者分析了天广直流控制保护系统改造完成后发生的3次双极线路保护动作事件,剖析其中直流线路突变量保护误动作的原因。根据天生桥换流站和广州换流站的实际录波和实际过程,结合厂家给出的突变量保护定值和整定思想,分析导致突变量保护误动作的因素。笔者给出了2个解决方案——降低低电压保护定值和增大突变量保护的动作延时,并经实践验证正确,为以后更好地实施直流控制保护系统国产化改造提供参考。

An assessment of potential interventions to reduce the totoaba illegal trade market
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract The illegal trade in totoaba (Totoaba macdonaldi) is causing adverse social, ecological, and economic impacts. This illegal activity is accelerating the overexploitation of totoaba and pushing the critically endangered vaquita (Phocoena sinus) closer to extinction.

Multiple‐stressor effects on leaf litter decomposition in freshwater ecosystems: A meta‐analysis
Functional Ecology, Volume 38, Issue 7, Page 1523-1536, July 2024.Read the free Plain Language Summary for this article on the Journal blog. Abstract Recent years have witnessed a surge in research on the effects of multiple stressors in freshwater ecosystems. While studies have increased, the synthesis of their findings into a broader understanding of ecosystem‐level effects remains an ongoing endeavour. Leaf litter

Dianci bileiqi, 2016 在大型建筑楼宇电气系统中,需要设置电涌过电压保护器（SPD）,对雷电或者其他瞬时过压的电涌进行保护。传统的建筑电气SPD电压保护装置采用本机振荡幅度调制的SPD电压保护器设计,但该设计装置会产生电涌过载失真,误差补偿性能。提出一种基于电压增益分配均衡处理的大型建筑电气SPD电压保护方法。进行了建筑电气SPD电压保护系统的等效电路设计,在SPD电压保护等效电路分析的基础上,构建SPD电压保护电力控制功率放大器,对SPD电压保护中出现较大偏差进行电磁耦合补偿 ...

Gaoya dianqi, 2004 给出了一种基于重合次数最少、快速隔离故障段线路的10kV配电网线路保护模式,即最少拍环网控制系统模式。该模式适用于绝大多数带辐射分支的环网控制系统,具有开关动作次数最少、对线路的冲击最小、快速隔离故障段线路、自动恢复非故障段线路供电的优点。分析了即使在三相“完全”短路,某控制器检测失误时最少拍的保护过程,提出了最少拍环网供电模式的一组参考参数,叙述了电压型保护模式和电流型保护模式的故障隔离过程,指出了其优点和不足。

Achieving conservation and restoration outcomes through ecologically beneficial aquaculture
Conservation Biology, Volume 38, Issue 1, February 2024.Abstract A range of conservation and restoration tools are needed to safeguard the structure and function of aquatic ecosystems. Aquaculture, the culturing of aquatic organisms, often contributes to the numerous stressors that aquatic ecosystems face, yet some aquaculture activities can also deliver ecological benefits.
