Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.ABSTRACT The infiltration of counterfeit, fraudulent, and suspect items into civil nuclear supply chains, notably within power generation and medical isotope production, poses severe safety and security threats. The ever‐increasing growth in nuclear installations (70 power plants are under construction and another 100 are in the planning stage) and the

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

The Two Faces of Introgression in Conservation Biology 基因渗入在保育生物学中的双重面貌
Integrative Conservation, Volume 4, Issue 3, Page 339-344, September 2025.Conservation biologist need to take into account the various aspects of introgression in their attempts to protect the species integrity and evolutionary potential of threatened species. To do so, they have to overcome the bias created by the Mayrian species concept that considers species as having distinct gene pools.

Shuitu Baochi Xuebao, 2020 为研究林分密度对土壤入渗性能的影响，以晋西黄土区5种密度（1 075，1 300，1 575，1 800，2 150株/hm2）刺槐（Robinia pseudoacacia Linn.）林为研究对象，采用双环入渗法测定其土壤入渗过程，并对入渗特征指标与土壤理化性质的相关性进行分析。结果表明：（1）不同密度刺槐林土壤入渗过程的变化规律一致，均经过瞬间入渗（0~5 min）、缓慢入渗（5~40 min）和稳定入渗（40 min后）阶段。（2）土壤初始入渗速率、稳定入渗速率 ...

Shuitu Baochi Xuebao, 2022 为揭示退耕对石漠化区露石岩—土界面土壤渗透特性的影响,以典型石漠化坡耕地为对照,选择休闲地、退耕灌草和果园为研究对象,采用环刀法研究了平直、外凸和内凹型露石岩—土界面土壤渗透特性。结果表明:(1)不同退耕类型岩—土界面土壤入渗过程及特征差异较大,从初始入渗率到稳定入渗率衰减幅度在0.350~55.756 mm/min,而不同岩—土界面形状间土壤入渗速率差异较大;(2)不同退耕类型岩—土界面土壤入渗速率的主要影响因素为毛管孔隙度和非毛管孔隙度,初始入渗率、平均入渗率和稳定入渗率均与毛管孔隙度呈极显著负相关(

Veterinary Dermatology, Volume 36, Issue 4, Page 474-484, August 2025.Background – Sporotrichosis is a chronic, mycotic infection caused by fungi of the genus Sporothrix. Zoonotic sporotrichosis occurs mainly through S. brasiliensis transmission, resulting from the organism's traumatic introduction via scratches or bites, or contact with exudate from contaminated cats.

Simulating the efficacy of wolf–dog hybridization management with individual‐based modeling
Conservation Biology, Volume 39, Issue 1, February 2025.In the photo, an introgressed adult wolf–dog in the Northern Apennines, Italy, not far from the city of Bologna. Part of a research program, this male has been sterilized and released back in its own pack with a Global Positioning Collar. Abstract Introgressive hybridization between wolves and dogs is a conservation concern due to its potentially ...

Digest of Middle East Studies, Volume 33, Issue 2, Page 108-124, Spring 2024.Abstract Integrating local militias in the counterinsurgency (COIN) operations in Sinai has achieved tangible successes. The presence of local fighters contributed to the penetration of the Islamic State—Sinai Province network. The integration of locals into the ongoing COIN process has imposed a degree of local participation in local governance and ...

Shuitu Baochi Xuebao, 2017 双环入渗仪是田间测量土壤入渗过程和饱和导水率最常用的经典方法，但入渗仪内外环尺寸均会影响其测定结果。设计7组不同内外径的双环入渗仪，在位于祁连山区的黑河上游平坦草地开展多次野外土壤入渗试验，对比分析双环入渗仪内外环尺寸对土壤入渗率和饱和导水率的影响。结果表明，双环入渗仪内径相同时，外径越大则稳定入渗率和饱和导水率越小；外径相同时，内径越小则稳定入渗率和饱和导水率越小。初始入渗率与双环入渗仪尺寸关系不显著，但稳定入渗率和饱和导水率与入渗仪缓冲指数呈显著负相关。综合考虑安装简便，用水条件 ...
