Offline Learning for Acknowledgment Optimization in Massive LoRaWAN Networks

open access: yesInternet Technology Letters, Volume 8, Issue 6, November/December 2025.
ABSTRACT LoRaWAN faces critical limitations in large‐scale deployments due to spectrum contention, duty‐cycle restrictions, and energy constraints. These challenges impact the reliability and responsiveness of bidirectional communication particularly when conventional acknowledgment mechanisms are used.

Body composition in patients with obesity‐related heart failure with preserved ejection fraction: A comparison study

open access: yesJournal of Parenteral and Enteral Nutrition, Volume 49, Issue 8, Page 1002-1011, November 2025.
Abstract Background Appendicular lean mass index is a major determinant of cardiorespiratory fitness in patients with obesity‐related heart failure with preserved ejection fraction (HFpEF). Moreover, appendicular lean mass index can be used to diagnose sarcopenia and sarcopenic obesity in this population.

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &Photonics Reviews, Volume 19, Issue 21, November 6, 2025.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...
