How New Issues Become Polarized: Partisan Triggers and Subsystem Shopping in Early AI Policymaking
Policy &Internet, Volume 18, Issue 1, March 2026.ABSTRACT Early AI policymaking in the United States appeared bipartisan, but subsequent developments raise the question of whether AI policy will become more polarized over time. To examine how partisanship takes root around novel policy issues, we perform a mixed‐methods study, analyzing survey data from 129 state legislators in 44 states and ...

Shuitu Baochi Xuebao, 2003 运用分形模型对不同紫色母质发育的土壤团聚体特征进行研究,结果表明:土壤团聚体粒径分布的分形维数与土壤团聚体结构破坏率存在极显著正相关(r=0.961**,n=8),与>0.25mm水稳性团聚体含量存在极显著负相关(r=-0.958**,n=8);不同紫色母质发育的土壤团聚体粒径分布的分形维数存在差异,棕紫泥土壤团聚体粒径分布的分形维数最高,暗紫泥土壤团聚体粒径分布的分形维数最低。土壤团聚体粒径分布的分形维数是评价土壤物理肥力和土壤抗蚀性的一个新指标。

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Underrepresentation of bats in Africa's protected areas
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Zhendong Ceshi yu Zhenduan为了提高分布式光纤传感器监测结构动态响应的精度并提高损伤诊断的准确性，运用长短期记忆神经网络，建立布里渊增益谱‑频率数据关系模型，确定布里渊光时域分析技术中振幅传输模式扫描的固定频率。基于分布式光纤振动传感信息沿光纤密集分布特点，通过计算应变传递率梯度，提出了基于分布式动应变传递率梯度的损伤指标。不同损伤程度的悬臂梁分布式光纤振动传感实验表明，该方法能够实现结构损伤位置的诊断，且对毫米级裂纹仍有较强的敏感性。
