Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

强台风下高压输电线路塔—线耦联体系的力学行为仿真分析二:动力响应分析
Gaoya dianqi, 2016 风载荷是影响高压架空输电线路安全运行的重要因素,为分析塔—线耦联体系的动力响应规律,以广东湛江某220 kV输电线路为背景,在ANSYS有限元开发环境下,建立三基塔两回线塔—线耦联体系有限元模型。基于Davenport脉动风速功率谱,考虑湛江当地气象条件,模拟生成风速时程,在风速时程作用下,对耦联体系进行风致动力响应分析,并将铁塔动力响应结果与拟静力计算结果进行对比。分析发现,动力分析铁塔顺线路位移是规范拟静力的5.2倍左右,垂直线路位移是静力分析的1.3倍左右 ...

A novel method coupling numerical and analytical methods for seismic dynamic response analysis of soil-structure interaction systems [PDF]
, 2014 本文提出了一种新的数值解与解析解耦合的理论和计算方法，研究土－结构相互作用(SSI)体系的地震动力响应。在SSI分析方法中，传统的基于频域内的解析方法只适用于简单的线弹性结构、刚性基础和等效线弹性的半无限大地基组成的体系中，具有较大的局限性。而基于非线性有限元的数值法，能较好的处理实际问题中的复杂结构，考虑地震中土和结构的非线性行为、土－结构之间的接触面以及土的边界等问题，但该方法计算量大。因此在子结构法的基础上，本文提出了一种新型的数值解与解析解耦合方法 ...

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species
Conservation Biology, EarlyView.Abstract An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected.

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, EarlyView.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Gaoya dianqi, 2021 为探究网侧设备对±800 kV换流变地震响应的影响,以某典型换流变—套管体系为对象,建立其单体有限元模型以及考虑网侧设备连接的耦联模型。网侧套管顶部滑动连接金具采用滑动接触单元进行了模拟,计算分析了地震作用下模型前20阶模态以及套管加速度、位移、应力响应。结果表明:①特高压换流变—套管体系前20阶频率接近地震卓越周期,震中易发生类共振;②网侧设备对换流变阀侧套管地震响应无影响,但会显著放大网侧套管顶部位移响应和根部应力响应;③地震作用下,网侧套管顶部连接金具内部的相对滑移响应显著。因此 ...
