Clinical and Translational Medicine, Volume 15, Issue 5, May 2025.EVs were isolated from plasma of ME/CFS patients and healthy controls at baseline, and 15 min and 24 h postexercise. Untargeted proteomics revealed dysregulation in energy metabolism, the complement system, and the endoplasmic reticulum stress response. Changes in EV protein levels postexercise are associated with post‐exertional malaise.

Antisaturation Carrier Tracking Technique for Ground‐Based Positioning Systems
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.Ground‐based positioning systems (GBPS) can offer high‐precision positioning in GNSS‐denied environments using carrier phase measurements but suffer from receiver front‐end saturation when processing strong signals from nearby base stations, limiting its usable positioning range. This paper proposes an antisaturation carrier tracking technique based on
