Configurations and Control Strategy of a Single Stage Grid Connected PV System [PDF]
In the grid-connected photovoltaic (PV) system, the array forms DC power. This generated power, a two-way grid process is called DC – DC – AC as a two-stage power conversion and, secondly, a DC-AC with a reduced circuit is called a single Stage Grid ...

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