Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.

Nurr1 Orchestrates Claustrum Development and Functionality

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Nurr1 (Nr4a2) is the master transcription factor to control claustrum morphogenesis and cell fate decision postmitotically by inhibiting intracellular G‐protein signaling. Nurr1 deficiency alters the transcriptomic profiles of subcortical claustral neurons into neocortical insular neurons, resulting in defected claustrum development, impaired axonal ...

Socio‐demographic and geographical patterns in forest and park use: Insights from 33 European countries

People and Nature, Volume 8, Issue 3, Page 611-632, March 2026.
Abstract Access to (urban) nature is vital for people's wellbeing, but this accessibility is not evenly spread across socio‐demographic groups, nor across the European continent. This paper fills a research gap by exploring the use patterns and accessibility of forests and parks across European cities, based on a standardised online survey of 10,462 ...

Energy efficiency enhancement using dynamic voltage restorer (DVR)

International Journal of Power Electronics and Drive Systems (IJPEDS), 2019
Dynamic voltage restorer (DVR) is a device that can compensate harmonic, voltage sag and voltage swell condition that exists in a three-phase system. Other than that, DVR can also be used to enhance the energy efficiency or energy saving by reducing excessive amount of incoming power via the reduction incoming voltage at allowable limit.

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

Experimental 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

Alzheimer'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.

Dynamic Voltage Restorer (Dvr) For Voltage Sag Mitigation

, 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.
