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 ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2017 Lightning voltage impulse due to the waves of storm surge rolling out the high voltage line to a substation causes current to flow in the buses that, due to magnetic effect, induces overvoltage in the secondary circuit.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
