Mitigation of Lightning Overvoltages Using STATCOM in Grid-Connected PV Systems [PDF]
Port Said Engineering Research Journal, 2020 Lightning strike causes a large lightning voltage injection into grid-connected PV systems at the point between inverter and transformer. The overvoltage resulting from the lightning-impulse voltage is a major concern for the multiple expensive ...

Leader Propagation Characteristics Under Positive Lightning Impulse Voltages
IEEE AccessLightning strikes on transmission lines often generate overvoltage, which is the primary reason for insulator string flashover. This overvoltage, with a rapid rise time of just a few microseconds, causes leader propagation characteristics to differ ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
