Chicken particle swarm optimization algorithm for MMSE equalization in MIMO systems
Franklin OpenThe high density of wireless devices operating close to populated areas can result in significant Inter-Symbol Interference (ISI). Further, Co-channel interference from neighboring networks and devices can disrupt communication and might decrease signal ...

An Information Theoretic Charachterization of Channel Shortening Receivers [PDF]
, 2013 Optimal data detection of data transmitted over a linear channel can always be implemented through the Viterbi algorithm (VA). However, in many cases of interest the memory of the channel prohibits application of the VA. A popular and conceptually simple

Exploring small‐world brain connectivity in aging and its relationship with cognitive reserve
Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 2, April/June 2026.Abstract INTRODUCTION The aging brain's vulnerability to decline emphasizes the importance of strategies preserving cognitive function and independence. As age‐related brain changes do not always match clinical symptoms, reserve, encompassing brain reserve (BR) and cognitive reserve (CR), has emerged as a key mechanism supporting resilience and ...

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.Abstract INTRODUCTION The locus coeruleus (LC) undergoes age‐related changes and is involved in Alzheimer's disease pathogenesis. Vagus nerve stimulation (VNS) may modulate LC activity and could be used therapeutically, but age‐related differences in VNS responses remain unexplored.
