Post‐COVID Fatigue Is Associated With Reduced Cortical Thickness After Hospitalization
ABSTRACT Objective Neuropsychiatric symptoms are among the most prevalent sequelae of COVID‐19, particularly among hospitalized patients. Recent research has identified volumetric brain changes associated with COVID‐19. However, it currently remains poorly understood how brain changes relate to post‐COVID fatigue and cognitive deficits.

Link Budget Analysis for LEO Satellites Based on the Statistics of the Elevation Angle
Link budgets are widely applied to evaluate communication links for low Earth Orbit (LEO) satellites. However, approaches to calculate the received power from LEO satellites have followed similar procedures to those for Geostationary (GEO) satellites and

Modulation and Signal Processing for LEO-LEO Optical Inter-Satellite Links
Nous étudions les aspects clés des communications optiques cohérentes sur les liaisons inter-satellites (ISL) pour les constellations ultra-denses de prochaine génération en orbite terrestre basse (LEO). Dans un premier temps, la pertinence des formats de modulation QPSK, 8-QAM et 16-QAM avec différents débits de symboles (28 GBaud, 60 GBaud et 120 ...

Implementation of Drug‐Induced Rhabdomyolysis and Acute Kidney Injury in Microphysiological System
A modular Muscle–Kidney proximal tubule‐on‐a‐chip integrates 3D skeletal muscle and renal proximal tubule tissues to model drug‐induced rhabdomyolysis and acute kidney injury. The coculture system enables dynamic tissue interaction, functional contraction monitoring, and quantification of nephrotoxicity, revealing drug side effect‐induced metabolic ...
