Multimodal Deep Learning‐Assisted Microstructural Evaluation System for Sintered NdFeB Magnets
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The performance of sintered NdFeB magnets, especially coercivity, is critically determined by their complex microstructure. However, a quantitative microstructural evaluation system (MES) is much needed but has long been missing in the community.

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Gaoya dianqi, 2010 介绍了同步关合技术的工作原理,对影响永磁操动机构开关的同步关合关键技术——参考信号的过零点精确检测和动作分散性的减少分别进行分析。利用FIR滤波的方法提取参考信号的过零点,通过仿真结果可以看出,该方法对于受干扰信号过零点的提取有较高的精确度,并提出实际采样过程中应用线性插值法得到过零点。分析得出引起开关动作时间分散性的因素主要包括操动机构动作时间的分散性、控制信号的分散性和预击穿的影响,应用BP神经网络和自适应算法补偿实时环境（温度和控制电压）下的操动时间可减小操动机构分散性 ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Rhetorical Diffusion and Policy Latency: Tracing AIPAC Influence in US–Iran Relations (2010–2026)
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT How do domestic interest groups shape the transition from diplomatic agreements to kinetic warfare? This research article addresses the methodological stagnation in foreign policy analysis by introducing a computational text‐as‐data pipeline to systematically quantify lobbying influence.

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Disruptive innovations often diffuse faster than inherited policy institutions can classify, assign jurisdiction, and govern them. In these early phases, the central struggle is often not yet about the stringency of substantive standards, but about prior questions of what the innovation is (its legal and administrative classification), who is ...

Shuitu Baochi Xuebao, 2019 以北京山区广泛分布的侧柏林为研究对象，分别采用水文学实测法（树干液流计结合大型蒸渗仪）和稳定同位素法对林分蒸散量进行定量拆分研究。结果表明：（1）在日尺度上，该林分的蒸散量和蒸腾量均显现为"单峰"型的变化曲线。林分总的蒸散量和蒸腾量均在正午前后达到最大值，分别为1.27，1.13 mm/h；（2）实测法和稳定同位素法对侧柏林蒸腾量占总蒸散量的计算结果分别为80.21%~89.63%和79.10%~98.71%。相比水文学实测法，稳定同位素法在小时尺度上误差为（3.97±3.53）%，而在日尺度上误差为 ...
