Adaptive stress coping is associated with cognitive resilience in at‐risk cognitively unimpaired older adults

open access: yesAlzheimer's &Dementia, Volume 21, Issue 11, November 2025.
Abstract INTRODUCTION Coping strategies are potentially modifiable factors that may contribute to cognitive resilience. We examined whether adaptive coping modifies the association between Alzheimer's disease (AD) pathology and cognitive decline.

Drivers of Phenotypic Variation Along a Late Pleistocene Range Expansion Route

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Understanding how interindividual variation within populations drives the evolution of biodiversity patterns is a major challenge in ecology and evolutionary biology. By reshuffling species distribution in space and time, Pleistocene climatic oscillations shaped the structure of biodiversity.

Improved Fault Ride Through Capability in DFIG Based Wind Turbines Using Dynamic Voltage Restorer With Combined Feed-Forward and Feed-Back Control

open access: yesIEEE Access, 2017
This paper investigates the fault ride through (FRT) capability improvement of a doubly fed induction generator (DFIG)-based wind turbine using a dynamic voltage restorer (DVR). Series compensation of terminal voltage during fault conditions using DVR is

Voltage compensation and power factor correction in distribution networks with DVR [PDF]

open access: yes, 2015
The stability analysis and voltage regulation in distribution systems, as well as power quality problems such as voltage sags, swells, due to connection and disconnection of large loads, short circuits and the presence of non-linear loads, require of the

Dynamic Voltage Restorer (Dvr) For Voltage Sag Mitigation

open access: yes, 2016
Voltage sags and swells in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe. The impact ranges from load disruptions to substantial economic losses up to millions of dollars.

Tau mediates the impact of amyloid and vascular disease burden on the trajectory of clinical symptoms

open access: yesAlzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION Amyloid (A) and vascular (V) pathologies often co‐occur and progress over decades. We leveraged chronicity, defined as the years above a biomarker‐positivity threshold, to examine how the timing of A and V relates to cognitive decline.

Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease

open access: yesMovement Disorders, Volume 40, Issue 8, Page 1584-1594, August 2025.
Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.
