Inferring alternative ecosystem states with field survey data
Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2256-2276, August 2026.Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Dianci bileiqi, 2013 输电线路在线监测是实现输电线路状态检测和检修的重要手段。为评价输电线路在线监测可靠性,采用层次分析法建立了以环境因素、监测装置本体、人员因素、管理因素的可靠性评价体系结构,在可靠性评价体系基础上建立了输电线路可靠性多级模糊综合评价模型,对武汉地区一条线路的在线监测的可靠性进行了评估,确定了该条线路的在线监测可靠性等级为差,可靠性差主要是由于装置本体原因引起的。

Politics &Policy, Volume 54, Issue 4, August 2026.ABSTRACT We theorize the notion of “fear of domination” and argue that people rely on a series of realist heuristics to gauge their support for an IO. Based on realist thinking, we hypothesize that individuals are less likely to support IOs that are subject to domination or manipulation.

Time's Sentimental Tale: Operationalizing Plot Within the Narrative Policy Framework
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT The Narrative Policy Framework (NPF) has proven to be a successful analytical tool for examining the role of narratives within the policy process; however, the analysis of plot is still understudied. This gap persists due to difficulty in developing valid and reliable measures of plot and a lack of plot operationalizations using longitudinal ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Laser powder bed fusion (LPBF) of Inconel 718 alloy inevitably introduces pronounced microstructural anisotropy, typified by columnar grains and robust crystallographic texture. This results in direction‐dependent fatigue behavior, raising critical reliability concerns for high‐stakes aerospace applications.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Ti3C2Tx MXene shows significant potential in the field of electromagnetic wave absorption; however, the wave absorption performance was hindered due to the impedance mismatch, which was caused by its inherent high dielectric constant. In this work, Ti3C2Tx MXene co‐assembled with molybdenum disulfide nanosheets and carbon coating layers (MXene/

Gaoya dianqi, 2019 可靠性分配是直流隔离开关底座系统可靠性设计的重要环节,其结果直接影响整机的设计方案。为了能够准确得到在一定约束条件下的可靠性优化分配结果,确立了基于直流隔离开关底座系统故障机理的可靠性分配方法,首先根据FTA和FMEA的故障分析结果,确定各个零部件的故障综合因子,然后将可靠性目标根据一定的数学关系式分配到各个零部件,从而实现直流隔离开关底座系统的总体可靠性有效地分配到各个零部件上。该方法不仅将FTA和FMEA两种故障分析方法相结合,而且还对原始可靠性分配函数进行了改进,提高了可靠性的分配效率 ...

Functional Ecology, Volume 40, Issue 7, Page 2332-2344, July 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.
