Torque priority control for PMSM DTC method
Dianzi Jishu Yingyong, 2018 A method of PMSM DTC method based on giving priority to the torque control was proposed due to the problem that the reference voltage vector was difficult to compute in PMSM SVM-DTC method. The reference voltage vector of making torque change quickly was

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Interpreting the effects of DNA polymerase variants at the structural level
Molecular Oncology, EarlyView.Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1982 The previous knowledge of the hobbing torques is useful to the strength-design for the hob teeth, the decision of optimum cutting conditions for the strength of the hob teeth and the analysis of vibrations on the hob machine. The hobbing torque is calculated from the cross sectional area of cut of the hob tooth and the specific cutting force of the ...
