Thermal Escape of Atomic Hydrogen on Mars: A Comprehensive View With a General Circulation Model

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mars loses water mainly through the photodissociation of water vapor, followed by the thermal escape of light hydrogen atoms. Observations have revealed large seasonal variations in hydrogen concentration in the upper thermosphere, peaking during southern summers and intensifying during dust storms.

Cyberattack Detection, Fault Estimation, and Fault‐Tolerant Control of Smart‐Grid Cyber‐Physical Systems

IET Smart Energy Systems, Volume 2, Issue 2, Page 102-119, June 2026.
A resilient estimation and control framework is developed for smart‐grid cyber‐physical systems to simultaneously detect cyberattacks and estimate physical faults. The proposed method ensures accurate estimation and robust performance under disturbances and sparse sensor attacks.

Culture, Economic Shocks and Conflict: Does Trust Moderate the Effect of Price Shocks on Conflict?*

Economic Record, Volume 102, Issue 337, Page 165-181, June 2026.
Internal conflict has affected most developing countries over the past several decades. Economic shocks are among the primary drivers of civil conflict. However, the empirical evidence on the impact of price shocks on the risk of conflict is mixed.
