Jianzhu Gangjiegou Jinzhan, 2022 地震作用下，减小耗能段的残余变形和优化自复位结构的耗能机制，是提高建筑结构震后功能恢复能力与抗震性能的重要方式之一。基于预应力钢绞线、滑移连接和短剪切形耗能段的力学性能，提出一种抗震性能良好的组合体。为探究组合体的抗震性能，采用校正的有限元分析方法对5个有限元模型进行分析，得到了组合体分析模型的滞回性能、自复位性能、耗能能力和等效塑性应变等抗震指标。有限元分析结果表明：组合体具有良好的承载力、耗能能力和自复位性能；组合体分析模型的损伤集中在可更换的耗能段上 ...

Dizhen xuebao, 2018 以云南丽江党校井为例，分析了水温基本动态和同震变化特征，并对水温前兆异常变化进行了讨论。基本动态方面，水温水位的对比分析和井温梯度结构显示，党校井的温度探头位于井孔水体与含水层连通的主要部位，含水层中补给水的温度较低，水温动态主要受水位泄流状态和水位变化的影响；同震方面，在水位均为振荡的情况下，水温同震变化形态在不同的泄流状态下存在明显的差异，自流期间为上升—下降—恢复型，非自流期间为下降—上升—恢复型，同震变化反映出的温度探头放置位置和低温水源补给的认识与基本动态分析获得的认识相一致；前兆方面 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Ceramic reinforcement is crucial for crafting ultrastrong and wear‐resistant metallic components. However, pronounced stress concentration and strain incompatibility at ceramic–metal interfaces often trigger microcrack initiation and ceramic spalling exacerbating friction under sliding conditions.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT This study successfully prepared a high‐palladium (Pd)‐loading (51 wt%) Pd/Al2O3 composite through multiple wet impregnation. The material exhibited excellent hydrogen isotope separation performance, with metal–support interactions endowing it with a higher plateau pressure and lower desorption temperature.

Threats to and management of Natura 2000 protected areas relative to agricultural practices
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Veterinary Dermatology, Volume 37, Issue 2, Page 236-246, April 2026.Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...

Veterinary Dermatology, Volume 37, Issue 2, Page 293-305, April 2026.Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...
