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.

Artificial intelligence in soil science
European Journal of Soil Science, Volume 76, Issue 2, March–April 2025.ABSTRACT Few would disagree that artificial intelligence (AI) holds potential for advancing knowledge and innovation. Over the past decades, substantial research has been devoted to the development and application of AI in soil science. While most of today's AI applications in soil science are related to machine learning (ML), AI also encompasses other

Radio Frequency Fingerprinting for WiFi Authentication Based on Detrended Fluctuation Analysis
IET Information Security, Volume 2025, Issue 1, 2025.Traditional physical‐layer authentication (PLA) approaches primarily rely on a limited set of hardware features, which restricts their robustness and accuracy in dynamic wireless environments. This paper proposes a novel PLA enhancement framework based on nonlinear signal analysis, introducing detrended fluctuation analysis (DFA) as a distinctive ...

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
