Translation and Validation of the Thai Version of the Telephone Interview for Cognitive Status and the Mini Montreal Cognitive Assessment in Older Adults

Brain and Behavior, Volume 16, Issue 1, January 2026.
Abstract Introduction This study aimed to translate and validate the telephone interview for cognitive status (TICS) and the mini montreal cognitive assessment (Mini MoCA) for use in older Thai adults and to compare their diagnostic validity for mild cognitive impairment (MCI) and dementia.

Low-Complexity Banded Equalizers for OFDM Systems in Doppler Spread Channels

EURASIP Journal on Advances in Signal Processing, 2006
Recently, several approaches have been proposed for the equalization of orthogonal frequency-division multiplexing (OFDM) signals in challenging high-mobility scenarios. Among them, a minimum mean-squared error (MMSE) block linear equalizer (BLE), based

Long‐Term Effect of Acetylcholinesterase Inhibitors on Behavioral and Psychological Symptoms of Dementia

International Journal of Geriatric Psychiatry, Volume 41, Issue 1, January 2026.
ABSTRACT Objective Behavioral and psychological symptoms of dementia (BPSD) are critical aspects of the clinical presentation of dementia. There is no universally accepted approach for the managment of BPSD, currently based first on a non‐pharmacological and subsequently on a pharmacological approach.

Oncology drug repurposing as a blueprint for Alzheimer's therapy

Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 1, January/March 2026.
Abstract Alzheimer's disease (AD) imposes substantial personal, social, and economic burdens, yet current therapies provide only modest slowing of clinical decline. Recent approvals of amyloid‐targeting antibodies confirm target engagement but also expose the limitations of single‐target strategies in a disease shaped by interacting processes ...

A Supervised Learning Method for High‐Performance Channel State Information Estimation

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a deep neural network (DNN)‐based method for channel state information (CSI) estimation, incorporating a Discrete Fourier Transform (DFT) step to reduce noise impact and improve learning accuracy. Simulation results demonstrate that the proposed method achieves superior channel estimation performance, particularly in noisy wireless ...

Adaptive Channel-Tracking Method and Equalization for MC-CDMA Systems over Rapidly Fading Channel under Colored Noise

EURASIP Journal on Advances in Signal Processing, 2010
A recursive maximum-likelihood (RML) algorithm for channel estimation under rapidly fading channel and colored noise in a multicarrier code-division multiple-access (MC-CDMA) system is proposed in this paper. A moving-average model with exogenous input (
