Orbital Decay of the Three SNIPE CubeSats During the Super Geomagnetic Storm in May 2024
Space Weather, Volume 24, Issue 8, August 2026.Abstract The Mother's Day (Gannon) geomagnetic superstorm of May 2024 produced extreme thermospheric heating and expansion, resulting in enhanced atmospheric drag on low Earth orbiting (LEO) satellites. We investigate storm‐time thermospheric drag and density variability using three satellites of the Small‐scale magNetospheric and Ionospheric Plasma ...

Optimized Joint Relay and Antenna Selection for Enhanced Full‐Duplex Relay Networks
Engineering Reports, Volume 8, Issue 7, July 2026.This study proposes a joint relay and antenna selection strategy for full‐duplex amplify‐and‐forward relay networks. By adaptively optimizing transmitter–receiver configurations based on channel conditions, the method reduces self‐interference, lowers outage probability, and symbol error rate, and enhances spectral efficiency, offering a scalable ...
