Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Dianci bileiqi, 2020 MOV静态下的功率损耗是影响其热稳定的重要因素,在考虑了老化因素对MOV功率损耗的影响后提出了老化程度变量并将其量化的新方法,并利用自适应模糊推理系统（ANFIS）将电压（V）、温度（T）、老化程度（AD）作为网络的输入,实验测量数据作为训练样本对MOV的功率损耗进行评估。研究表明:ANFIS可有效评估MOV的功率损耗,其最大相对误差为8.

Gaoya dianqi, 2023 高压电缆长期运行过程中温度引起的绝缘材料热老化是影响其整体绝缘性能的重要因素。通过对高压电缆主绝缘层切片取样，研究分析了不同老化程度试样的微观形貌、官能团、结晶度、交联度等理化性能变化规律，测试分析了不同老化程度试样的电阻特性、介电性能和击穿特性，仿真模拟了不同温度下交联聚乙烯分子链的运动情况，进一步讨论了热老化对其微观结构的破坏演变机理。研究结果表明，老化2 160 h后试样的晶区结构破坏较为严重，随着老化时间的延长，相邻晶区的间距增大，晶区排列松散，无定型区面积增大；羰基指数从3.88%增大至11 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines multilingual practices in research interviews, focusing on English lexical insertions in Chinese‐language research interviews with teachers of Chinese in Australian secondary schools, and treating these code‐switches as analytically meaningful rather than incidental.

黑龙江老爷岭东北虎国家级自然保护区土地利用与景观格局变化研究
野生动物学报, 2021 土地利用和景观格局变化研究是自然保护区制定管理和保护规划的重要依据。本研究以黑龙江老爷岭东北虎国家级自然保护区1999—2019年3期的土地利用数据为基础，利用动态度与转移矩阵模型对该区的土地利用变化进行分析；选择斑块数量和香农多样性等景观指数对其景观格局变化进行研究。结果表明，林地是老爷岭保护区主要的土地利用类型，约占自然保护区总面积的95%，且1999—2019年呈稳定趋势（K=-0017）。从景观格局变化来看，老爷岭保护区的景观呈破碎化趋势，其中斑块数量和香农多样性指数变化最大。从时间跨度来看 ...

The Rhetoric of Disenchantment: Ghost Belief and Secular Critique in Early Twentieth‐Century China
Cognitive Science, Volume 50, Issue 1, January 2026.Abstract This study presents the first large‐scale empirical analysis of how ghosts and spirits were debated during China's early twentieth‐century secular transformation. Using a novel dataset of over 2000 digitized texts—including newspapers, periodicals, and essays from 1890 to 1949—we combine close reading, AI‐assisted annotation, and statistical ...

Gaoya dianqi, 2018 为分别评估变压器油纸绝缘的老化程度和水分含量,文中通过加速热老化试验和吸潮实验制备了不同老化程度下含水量不同的油浸绝缘纸试品,测试了试品的介损因数频谱和阻抗相位频谱,分析了老化、水分对油纸绝缘频域介电谱特性的影响。采用多输出支持向量回归算法（multi-output support vectorregression,M-SVR）逼近频域介电谱曲线与油纸绝缘老化和水分之间的非线性映射关系,据此预测油纸绝缘试品的老化程度和水分含量。研究表明,对于含水量在0.5～5.6%范围内、具有不同老化程度的试品,M ...
