Active voltage damping method with negative DC link current feedback in electric and hybrid electric transmissions

Научно-технический вестник информационных технологий, механики и оптики
Electric and hybrid electric transmissions in traction drive have a limited capacity power source. Since the traction drive operates in the torque source mode, the DC link voltage becomes unstable and goes into oscillatory mode.

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 ...

Automatic Power Flow Control Strategy in Hybrid Microgrids: Development and Validation using Controller Hardware-in-the-Loop

Eletrônica de Potência
Research on hybrid microgrids has attracted significant interest mainly due to the advantages that this topology offers compared to a solely direct current (DC) or alternating current (AC) microgrid.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
