First Coincident Radar and Optical Observations of a Meteor Radio Afterglow
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract It has been hypothesized that Meteor Radio Afterglows (MRAs) occur due to resonant transition radiation (RTR) where suprathermal electrons emit as they pass through electron density inhomogeneities in a turbulent plasma. Meteor trails are thought to produce suprathermal electrons through anion oxidation, which can be identified through meteor ...

On Robustness of Massive MIMO Systems Against Passive Eavesdropping under Antenna Selection
, 2018 In massive MIMO wiretap settings, the base station can significantly suppress eavesdroppers by narrow beamforming toward legitimate terminals. Numerical investigations show that by this approach, secrecy is obtained at no significant cost.

Antipode, Volume 58, Issue 2, March 2026.Abstract The paper examines the existing relationships between universities and Frontex, investigating and problematising the intersection between the higher education sector and the violence of the European border regime. We introduce the concept of positivist dissonance to conceptualise these relationships within the wider “industrial‐military ...
