Deep‐Learned Channel Estimation for MIMO‐OFDM System by Exploiting Frequency‐Space Correlation
Electronics Letters, Volume 62, Issue 1, January/December 2026.In massive MIMO–OFDM systems, accurate channel state information acquisition is vital for reliable transmission. Traditional methods fail to fully exploit sparse channel correlation, so an attentive residual autoencoder network is proposed. It uses an autoencoder with attention and residual connections to capture frequency–space correlation, and ...

Electronics Letters, Volume 62, Issue 1, January/December 2026.1.This paper develops an analytical model to calculate the signal‐to‐interference ratio performance of mobile orthogonal frequency division multiplexing underwater acoustic (UWA) communication systems. 2.The model accounts for UWA channel distortion and non‐uniform Doppler effects, maintaining high accuracy across a range of Doppler shift magnitudes. 3.

IET Networks, Volume 15, Issue 1, January/December 2026.This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

Aging Cell, Volume 25, Issue 1, January 2026.We report the development and application of a mouse ovarian somatic organoid model to elucidate a fundamental new understanding of the cell biology of the aging ovarian microenvironment. ABSTRACT Ovarian somatic cells are essential for reproductive function, but no existing ex vivo models recapitulate the cellular heterogeneity or interactions within ...

Graded Calorie Restriction Causes Graded Slowing of Epigenetic Ageing in Mice
Aging Cell, Volume 25, Issue 1, January 2026.Graded calorie restriction in male mice modified epigenetic signatures of the liver and slowed ageing rate in a graded manner. ABSTRACT DNA methylation variation is associated with chronological ageing. Calorie restriction (CR) prolongs lifespan and healthspan in many species.
