Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

The Detection of Shaft Misalignments using Motor Current Signals from a Sensorless Variable Speed Drive

, 2014
Shaft misalignments are common problems in rotating machines which cause additional dynamic and static loads, and vibrations in the system, leading to early damages and energy loss.

Torque Ripple Minimization of Reduced DC‐Link Capacitor PMSM Drives Based on Optimal Current Injection Strategy

IET Power Electronics
Permanent magnet synchronous motor (PMSM) drives with reduced DC‐link capacitance face challenges such as increased torque ripple and poor dynamic performance due to low‐frequency harmonic distortions.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
