Free \(\mu ^{+}\mu ^{-}\) and Bound-free \(e^{+}e^{-}\) Pair Production in Relativistic Heavy-ion Collisions

In our previous studies, we calculated the cross section for the production of free \(\mu ^{+}\mu ^{-}\) pairs using a probability function dependent on the impact parameter, and also, we computed bound-free \(e^{+}e^{-}\) pair production cross section. In this study, unlike the...

Early Lean Tissue Loss and Nutritional Challenges Following Sleeve Gastrectomy in a Kidney Transplant Recipient: A Case Report

Background/Objectives: Obesity after kidney transplantation impairs graft function, but the time course of lean tissue loss after sleeve gastrectomy in this population is poorly described. Methods: A 46-year-old woman underwent sleeve gastrectomy five years after kidney transplan...

Deep learning-based stress detection using multimodal biosignals

Abstract Stress-related health problems drive an urgent need for sensitive, real-time monitoring devices capable of capturing psychophysiological stress dynamics in natural settings. This study presents a stress detection system that uses deep learning, combining synchronized phy...
