Synchronisation and echo detection in GSM-R and GSM repeaters

Radio repeaters in communication systems are used to extend the coverage where the base stations cannot reach directly, such as indoors, in tunnels, and obstructed mobile reception areas. The repeaters in the downlink receive signals from base stations, amplify them, and then retransmit them.

Four‐Peak Structure on Equatorial Ionization Anomaly Crests During the May 2024 Geomagnetic Storms

Space Weather, Volume 23, Issue 12, December 2025.
Abstract This study investigates the four‐peak electron density structure in the Equatorial Ionization Anomaly (EIA) during the intense geomagnetic storms of 10–20 May 2024, utilizing dayside data at ∼500 km from the China Seismo‐Electromagnetic Satellite (CSES‐01).

VAMPIRE: Using a Random Forest to Forecast Earth's Outer Van Allen Radiation Belt

Space Weather, Volume 23, Issue 12, December 2025.
Abstract The outer Van Allen radiation belt is highly dynamic in both strength and location, being driven by several distinct physical processes, making it difficult to predict for spacecraft operators. Forecasting models exist, in part, to minimise potential damage caused by this natural hazard.

Microclimate refugia shape microclimatic niches and predict individual variability in post‐breeding migration in a partially migratory species

Journal of Animal Ecology, Volume 94, Issue 12, Page 2527-2541, December 2025.
The niche is characterized along a gradient of temperature and microclimate refugia. Individuals in breeding areas with low microclimate refugia availability are more likely to cover larger distances to post‐breeding areas, increasing exposure to risks.

A Pilot Investigation of the Hidden Communities Associated With Dryas octopetala L. (Rosaceae) in Svalbard Using DNA Metabarcoding

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
A single marker revealed a considerable diversity of organisms associate with Dryas octopetala. The rhizosphere contains more taxa than the phyllosphere. Some taxa are cited for the first time in the Svalbard Archipelago. The use of different DNA marker will increase diversity data in the Svalbard Archipelago.
