YOLO‐Based Detection and Localization of Rocket Induced Traveling Ionospheric Disturbances

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract During rocket launches, atmospheric disturbances significantly impact the ionosphere, generating Traveling Ionospheric Disturbances (TIDs). These disturbances can affect radio communications and navigation systems and may pose risks to high‐speed aerospace vehicles.

Quantifying Colonisation Pressure as a Driver of Secondary Spread During the Dreissena polymorpha Invasion of German River Networks

Freshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Biological invasions have become a major component of global change, yet the processes governing secondary spread after initial introductions remain insufficiently resolved. A specific and central gap is the lack of a spatially explicit and temporally dynamic quantification of colonisation pressure, despite its presumed importance for ...
