Reduced triacylglycerols and lipid droplets are associated with resilience to Alzheimer's disease
Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.Abstract INTRODUCTION Although it has become clear that alterations in lipid metabolism are associated with Alzheimer's disease (AD), it is unclear how they contribute to both cognitive decline and the pathophysiology of AD. METHODS Lipidomics and activity‐based protein profiling (ABPP) were performed in the frontal cortex of control, AD and resilient ...

A Massive Grant‐Free Random Access Scheme Based on Spectrum Sensing and Preamble Delay
IET Communications, Volume 20, Issue 1, January/December 2026.This paper introduces cognitive radio (CR) and preamble delay (PD) to reduce access collisions, together with non‐orthogonal multiple access (NOMA) to improve spectrum efficiency, and thus proposes an efficient CR‐NOMA‐PD‐based massive grant‐free random multiple access scheme.

Grouping-Based Random Access Collision Control for Massive Machine-Type Communication
, 2017 Massive Machine-Type Communication (mMTC) is expected to be strongly supported by future 5G wireless networks. Its deployment, however, is seriously challenged by the high risk of random access (RA) collision. A popular concept is to reduce RA collisions

Communication‐Security Co‐Design for Federated Learning in Grant‐Free NOMA IoT Networks
IET Communications, Volume 20, Issue 1, January/December 2026.This article presents SA‐PPO, a Security‐Aware Proximal Policy Optimisation framework for federated learning over grant‐free NOMA (non‐orthogonal multiple access) in IoT networks. By jointly optimising access control, resource allocation, and trust‐weighted aggregation using cross‐layer indicators, SA‐PPO enhances both communication reliability and ...
