Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Many metallic components are frequently subjected to coupled environments of friction and vibration, stemming from interfacial contact and relative motion between mating parts or external stimuli. Consequently, it is imperative for these components to exhibit a synergy of high wear resistance and superior damping properties.

Jianzhu Gangjiegou Jinzhan, 2014 介绍了一种在梁腹板及下翼缘开孔,并在翼缘开孔处安装摩擦阻尼器的新型节点。利用有限元软件ANSYS分析了铝合金滑动板与梁下翼缘之间的摩擦系数、开孔宽度、开孔距柱翼缘距离和开孔高度等参数变化对新型节点抗震性能的影响,并对各系列新型节点试件与传统节点试件的抗震性能进行了分析比较。分析结果表明:各系列新型节点试件与传统节点试件的滞回曲线都比较饱满,表现出了较好的滞回性能。但各系列新型节点试件的延性及耗能能力要远远优于传统节点试件,且各系列新型节点试件都能够迫使塑性铰远离节点区,而出现在开孔处 ...

Jianzhu Gangjiegou Jinzhan, 2021 为了研究部分包裹混凝土组合(PEC)柱(弱轴)与型钢梁对穿高强螺栓端板连接节点的抗震性能,考虑端板厚度、盖板厚度以及节点构造形式3个参数,设计了两种不同构造的梁柱节点,对其进行低周往复荷载试验和有限元模拟,分析了各设计参数对试验节点滞回性能、承载能力、节点刚度、延性和耗能能力等指标的影响。研究结果表明:盖板厚度由14mm增加至16mm时,节点承载力提高了33.91%,初始刚度提高了14.9%,延性降低了18.9%;端板厚度由12mm增加至14mm时,节点承载力提高了19.93%,初始刚度提高了15.1%,

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Inferring alternative ecosystem states with field survey data
Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2256-2276, August 2026.Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Do Criminalization Policies Impact Local Homelessness?
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Local criminalization policies draw on the logic of deterrence to levy costs on individuals who engage in behaviors that are closely associated with various public concerns, such as those criminalizing behaviors associated with homelessness, thereby potentially reducing community‐level costs.
