Airgap-Harmonic-Oriented Partitioned Design Method of PMV Motor with Improved Torque Performances
CES Transactions on Electrical Machines and SystemsHere, we introduce a partitioned design method that is oriented toward airgap harmonic for permanent magnet vernier (PMV) motors. The method proposes the utilization of airgap flux harmonics as an effective bridge between the torque design region and the

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
