Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.

Jianzhu Gangjiegou Jinzhan, 2023 玻璃幕墙已被广泛应用于建筑结构中，但目前的设计主要针对静力荷载，对可能发生的爆炸等意外事件所产生的冲击荷载作用尚缺乏可靠研究。对爆炸冲击下的玻璃进行数值分析时，多数研究模型将边界条件过度简化，使玻璃面板直接承受爆炸冲击，忽略了支承体系中诸如框架、垫片、结构胶、滑移块等元件的缓冲作用。这种差异在中空夹层玻璃系统上更为明显，导致数值分析难以精确地模拟结构系统在冲击荷载作用下的响应。为此，对一玻璃幕墙系统进行足尺爆炸冲击试验研究，并采用LS-DYNA软件进行了精细化建模 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...

Contribution of microcosm experiments to conservation science
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.

Jianzhu Gangjiegou Jinzhan, 2013 为了考察国产Q460高强钢焊接箱形压弯构件的力学性能,以数值积分法和有限单元法对7个已有焊接箱形压弯构件试验进行了数值分析。试件宽厚比分别为8、12、18,长细比分别为35、50、80。介绍的数值模型中考虑了实测的初始挠度、初始偏心及残余应力对构件极限承载力的影响,采用简化的残余应力分布模型、实测残余应力分布与理想弹塑性材料模型、线性强化材料模型相组合,对Q460高强钢焊接箱形压弯构件的极限承载力与荷载-挠度曲线进行了数值计算。为了验证数值分析的准确性,将预测结果与已有试验结果进行了对比,分析结果表明 ...

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Jianzhu Gangjiegou Jinzhan, 2018 屈曲约束钢板联肢剪力墙结构通过在整体墙中部开设竖向贯通的洞口并均匀布置屈曲约束钢板组件来改进传统联肢剪力墙结构的抗震性能。通过算例对比了整体墙及基于该结构改进的屈曲约束钢板联肢剪力墙结构在地震时程作用下的动力响应,发现了后者在减小地震响应上的优越性,具有良好的抗震性能。同时,提出了屈曲约束钢板联肢剪力墙的弹塑性分析简化模型,并根据理论分析,给出了简化模型中相应参数的设计公式。最后通过原模型及简化模型在地震时程曲线下的动力响应,验证了所提出的弹塑性分析简化模型的准确性和高效性。
