Dynamic Performance of Parallel Heterogeneous Grid-Forming Inverters During Islanding and Grid Resynchronization

IEEE Access
Modern power systems with high inverter penetration face reduced inertia and increased frequency instability during disturbances, necessitating grid-forming inverters (GFMs) that emulate synchronous-machine dynamics.

FASLG Derived from Fibroblasts in Hydroxyapatite‐Rich Microenvironment Induces Urothelial Anoikis to Trigger Randall's Plaque Exposure

Advanced Science, EarlyView.
Randall's plaques (RP) serve as the nidus for calcium oxalate (CaOx) kidney stones. The current study reveals that hydroxyapatite (HAP) crystals activate the THY1–GSK3α/β–β‐catenin axis in renal interstitial fibroblasts (hRIFs), inducing FASLG secretion.
