A Review of Overcurrent Protection in Smart Grids Under Cyber‐Physical Threats With a Cyber‐Physical Evaluation Framework

Energy Science &Engineering, EarlyView.
By manipulating current and voltage measurements, an assailant can induce unwanted relay action while attempting to avoid detection. Detecting advanced cyber intrusions in power protection environments requires specialised data analysis and anomaly detection methods.

HOUSING RETROFIT AND THE JUST TRANSITION IN THE METROPOLIS: Governance, Redistribution, and Inequality in London and Barcelona

International Journal of Urban and Regional Research, EarlyView.
Abstract Metropolises are rapidly becoming spaces of stark inequalities. While much literature has emphasized the metropolitan scale as a driver of agglomeration economies, recent scholarship highlights either the ungovernable nature of large metropolises or the weak redistributive capacity of their governments as key causes of increasingly unequal ...

Responses of Soil Arthropod Communities to Varying Shading Levels in Agriphotovoltaic Systems

Integrative Zoology, EarlyView.
Soil fauna was primarily influenced by crop type and season rather than AgriPhotovoltaic (APV) panels. Elevated panels increased soil temperature and soil organic matter in early wheat stages, while shading enhanced soil moisture for tomatoes, benefiting moisture‐sensitive taxa.
