Operationalizing diffusion magnetic resonance imaging positivity for detection of vascular contributions to impairment and dementia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION White matter lesions on fluid‐attenuated inversion recovery magnetic resonance imaging (FLAIR‐MRI) reflect small vessel disease (SVD) and aid in identifying vascular contributions to impairment and dementia (VCID). Emerging diffusion MRI (dMRI) biomarkers are sensitive to early SVD but the lack of validated approaches for defining

Associations among sleep quality, cognitive decline, and Alzheimer's disease pathology in older adults: A longitudinal study

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION This study aimed to investigate whether sleep quality predicts cognitive/functional decline, and whether Alzheimer's disease (AD) pathology modifies these relationships. METHODS The Pittsburgh Sleep Quality Index was administered to 326 older adults (113 cognitively normal, 192 mild cognitive impairment, 21 dementia; mean age = 66.

Remarkable Stability Improvement of ZnO TFT with Al2O3 Gate Insulator by Yttrium Passivation with Spray Pyrolysis

open access: yesNanomaterials, 2020
We report the impact of yttrium oxide (YOx) passivation on the zinc oxide (ZnO) thin film transistor (TFT) based on Al2O3 gate insulator (GI). The YOx and ZnO films are both deposited by spray pyrolysis at 400 and 350 °C, respectively. The YOx passivated

Association of cognitive impairment and APOE ε4 with Centiloids in Hispanic and non‐Hispanic White cohorts

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Weak associations of apolipoprotein E (APOE) ε4 with cognitive impairment have been reported in Hispanic cohorts. To determine if APOE ε4 associates with brain amyloid load differently in Hispanic and non‐Hispanic White (NHW) cohorts, we analyzed reported Centiloid values from studies that conducted amyloid positron emission ...

The impact of cognitive behavioral therapy for insomnia on cognitive performance and amyloid beta in older adults: A randomized controlled trial

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Insomnia is associated with increased risk for Alzheimer's disease (AD). It is unknown how cognitive behavioral therapy for insomnia (CBT‐I) impacts two hallmarks of AD progression, cognitive performance and beta‐amyloid (Aβ) burden.

Research on ADRC of Double Buck Inverter

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The traditional double buck full bridge inverter adopts the hysteresis current control mode, and the current is in the half cycle. Because of its no bridge arm through, high voltage utilization and high efficiency, it is widely used. Based on the disturbance caused by power supply fluctuation, external noise and system parameter

Dementia etiology classification using NULISA plasma biomarkers and machine learning

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Accurate ante mortem differentiation among dementia etiologies remains challenging, particularly for atypical or mixed clinical presentations. Multiplexed plasma proteomics paired with supervised machine learning offers a minimally invasive and accessible approach for differential diagnosis.
