Sub‐MeV Electron Precipitation Driven by EMIC Waves: New Insights From CIRBE/REPTile‐2 Measurements

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves are recognized as a key driver of relativistic (>1 MeV) electron loss in Earth's magnetosphere. Growing evidence also suggests that EMIC wave can efficiently scatter sub‐MeV electrons, although the precise energy range and the underlying physical mechanisms remain debated.

Defense Algorithm Based on Reinforcement Learning and Digital Twin for Distribution Protection Devices Adversarial Samples

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Power system protection devices are vulnerable to adversarial samples. We propose a digital twin and reinforcement learning framework. It trains a virtual model within safe operational boundaries, reducing the false operation rate to below 3.5%. The model's inference delay is under 10 ms, meeting real‐time protection requirements.

AI‐Driven Optimization of a Hybrid PV–Wind–BESS Microgrid for a Rural Educational Institution in Developing Countries

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2839-2873, June 2026.
An AI‐driven CNN–LSTM forecasting framework is integrated with HOMER Pro to optimally design a grid‐connected PV–wind–BESS microgrid for a rural school in Bangladesh, achieving 91.7% renewable penetration, low energy cost (0.0397 USD/kWh), and an 81.5% reduction in CO2 emissions. ABSTRACT Hybrid renewable microgrid planning in HOMER Pro often relies on

Values and visibility: How CEO activism influences private and public consumer choices

open access: yesStrategic Management Journal, Volume 47, Issue 6, Page 1523-1551, June 2026.
Abstract Research Summary Firms' and executives' stances on controversial issues affect consumer behavior. This “political consumerism” might be motivated by ideology and a desire to signal to peers, and thus vary for private and public purchases. We conduct an experiment with 1198 consumers to study how purchase visibility affects responses to CEO ...
