Systematic Component‐Level Characterization of Electricity Transmission Infrastructure for Space Weather Risk Assessment

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Space weather risk assessment is constrained by the lack of available asset information needed to model geomagnetically induced currents (GICs) in electricity transmission infrastructure. We propose a systematic method that enables risk analysts to collect their own open‐source substation data.

Leveraging recurrent graph neural networks to improve geospatial estimation of equine West Nile Virus outbreaks

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
These findings contribute to ongoing efforts to mitigate the impact of WNV by refining our understanding of the spatial determinants of virus transmission, informing evidence‐based interventions and enhancing preparedness and response strategies. This framework supports targeted intervention strategies, such as conducting vaccine campaigns prior to ...

Long-term field measurement and characteristics of lightning-induced overvoltages on 10 kV distribution lines in high-altitude mountainous areas and optimization of insulation coordination

Results in Engineering
Aiming at the lack of measured data on lightning overvoltages in operational distribution networks and the irrationality of insulation coordination based on standard lightning impulse waveforms, this paper carries out large-scale and long-term ...

It Takes Two to Tango: A Pluralist Account for Building Comprehensive Explanations in Human Evolution

American Anthropologist, Volume 128, Issue 3, Page 494-510, September 2026.
ABSTRACT The evolutionary study of human dispersal is a key topic in biological anthropology. However, recent research has revealed inconsistencies between molecular and anatomical data across different timescales and geographic regions. Despite increased interdisciplinary dialogue, these discordances are rarely analyzed in depth or interpreted for ...

Behind Closed Doors: How Boardroom Silence and Implicit Theories Shape Corporate Governance

Corporate Governance: An International Review, Volume 34, Issue 5, Page 1015-1035, September 2026.
ABSTRACT Research Question/Issue Why do directors, despite formal authority and oversight responsibilities, remain silent in the boardroom, and how does such silence shape governance outcomes? Research Findings/Insights Silence in boards is not a passive absence but a routinized governance practice.
