Limited musculoskeletal benefits of artificial gravity combined with cycling during bed rest: Results from the BRACE study

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 1181-1190, 1 March 2026.
Abstract Prolonged exposure to microgravity, simulated via 6° head‐down tilt bed rest (HDT), induces musculoskeletal deconditioning and negatively impacts body composition. This study evaluated whether a combination of aerobic exercise with artificial gravity (AG) offers superior protection in comparison to exercise alone.

Cerebrovascular regulation dynamics and Alzheimer's neuroimaging phenotypes

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Cerebrovascular dysfunction may contribute to Alzheimer's disease (AD) pathogenesis. We examined how novel cerebral hemodynamic markers relate to neuroimaging phenotypes associated with AD dementia in cognitively impaired and unimpaired older adults.

AC voltage sag-swell compensator based on unified non-inverting and inverting output voltage AC chopper [PDF]

open access: yes, 2016
This paper proposes a unified AC chopper topology that can generate both non-inverting and inverting AC voltages. It is therefore suitable for compensating utility voltage sag-swell in domestic consumer and industry infeeds.

Intimate Partner Violence Intervention Strategies in the Dental Setting: A Scoping Review

open access: yesDental Traumatology, Volume 42, Issue 1, Page 6-23, February 2026.
ABSTRACT Background Intimate partner violence is a global issue. Dental settings are currently thought of as novel places for IPV support, with little known about the characteristics and effectiveness of current interventions. Objectives This scoping review explores the characteristics and effectiveness of current IPV interventions in dental settings ...

Impact of noise on the behaviour and biochemical parameters of the crayfish Cherax quadricarinatus and Cherax destructor

open access: yesJournal of Zoology, Volume 328, Issue 2, Page 146-164, February 2026.
The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of
