Integrated digit‐in‐noise testing for hearing and cognitive screening

open access: yesAlzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Hearing loss and cognitive decline often coexist in aging, and reduced audibility can bias cognitive screening. We evaluated integrated digit‐in‐noise (iDIN) testing for paired screening. METHODS Among 962 community‐screened adults 55 years of age or older, 495 had linked audiometry, iDIN, and the Hong Kong version of the Montreal

Blind Channel Equalization with Colored Source Based on Constrained Optimization Methods

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
Tsatsanis and Xu have applied the constrained minimum output variance (CMOV) principle to directly blind equalize a linear channel—a technique that has proven effective with white inputs.

Gut Microbiota and Ischemic Stroke: From Pre‐Stroke Dysbiosis and Acute‐Phase Changes to Therapeutic Applications

open access: yesBrain and Behavior, Volume 16, Issue 8, August 2026.
Abstract Purpose Ischemic stroke poses a major global health burden, and growing evidence points to the microbiota–gut–brain axis as an important contributor to stroke pathophysiology and recovery. The purpose of this review is to summarize current knowledge on bidirectional gut‐brain communication in stroke, establishing gut dysbiosis as an upstream ...

MMSE decision feedback equalizer from channel estimate [PDF]

open access: yesThe 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003
In digital radio transmission over frequency selective channels, the minimum mean-square error decision feedback equalizer (MMSE-DFE) is widely recognized as an efficient equalization scheme. In order to compute the coefficients of the feedforward and feedback filters of the MMSE-DFE, both the channel impulse response (CIR) and the variance of the ...

Savor‐Aging: The Art of Savoring Positive Emotions in Older Adulthood—A Randomized Controlled Trial

open access: yesApplied Psychology: Health and Well-Being, Volume 18, Issue 4, August 2026.
Abstract Savoring has been identified as a promising strategy to foster emotional and psychological well‐being and to reduce depression in elders. However, research on online savoring interventions for this population remains limited. This registered RCT aimed to examine the effectiveness of a 3‐week online intervention (six activities), Savor‐Aging ...

Application of time-reversal with MMSE equalizer to UWB communications [PDF]

open access: yesIEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005
We propose to apply a technique called time-reversal to UWB communications. In time-reversal a signal is precoded such that it focuses both in time and in space at a particular receiver. Spatial focusing reduces interference to other co-existing systems.

Time-Varying FIR Equalization for MIMO Transmission over Doubly Selective Channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
We propose time-varying FIR equalization techniques for spatial multiplexing-based multiple-input multiple-output (MIMO) transmission over doubly selective channels. The doubly selective channel is approximated using the basis expansion model (BEM),

Chicken particle swarm optimization algorithm for MMSE equalization in MIMO systems

open access: yesFranklin Open
The 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 ...
