Accurate reactive power sharing and voltage-frequency recovery strategy for multiple grid-forming converters based on consensus algorithms

open access: yesEnergy Reports
In isolated AC microgrids, parallel multi-inverter systems face challenges in precisely distributing reactive power output from distributed generation (DG) units due to varying DG parameters and mismatched line impedances.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
