PMSG-Based Wind Energy Conversion Systems Integration Into DC Microgrids With a Novel Compact Converter

open access: yesIEEE Access, 2020
DC microgrids (DC-MGs) are recognized as an efficient alternative for common AC-MGs. DC-MGs need fewer power electronic converters since most of distributed generation (DG) units and electronic loads operate with DC voltage.

Characterizing Cutaneous α‐Synuclein Deposition and Seeding Activity in Parkinson's Disease Subtypes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cutaneous phosphorylated α‐synuclein (p‐syn) and α‐synuclein seeding activity are promising biomarkers for Parkinson's disease (PD), but their clinical value remains uncertain due to disease heterogeneity. This study evaluates these two biomarkers in PD patients to inform phenotype‐specific diagnosis and disease severity assessment ...
