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

A Method to Accurately Estimate the Muscular Torques of Human Wearing Exoskeletons by Torque Sensors [PDF]
Sensors, 2015 In exoskeletal robots, the quantification of the user’s muscular effort is important to recognize the user’s motion intentions and evaluate motor abilities. In this paper, we attempt to estimate users’ muscular efforts accurately using joint torque sensor which contains the measurements of dynamic effect of human body such as the inertial, Coriolis ...

Non-equilibrium spatial distribution of Rashba spin torque in ferromagnetic metal layer
, 2012 We study the spatial distribution of spin torque induced by a strong Rashba spin-orbit coupling (RSOC) in a ferromagnetic (FM) metal layer, using the Keldysh non-equilibrium Green's function method.

Indeterminacy, Memory, and Motion in a Simple Granular Packing
, 2004 We apply two theoretical and two numerical methods to the problem of a disk placed in a groove and subjected to gravity and a torque. Methods assuming rigid particles are indeterminate -- certain combinations of forces cannot be calculated, but only ...

Molecular Oncology, EarlyView.Detection of extrachromosomal circular DNA (eccDNA) in plasma samples from EGFR‐mutated non‐small cell lung cancer patients. Plasma was collected before and during treatment with the EGFR‐tyrosine kinase inhibitor osimertinib. Plasma eccDNA was detected in all cancer samples, and the presence of the EGFR gene on eccDNA serves as a potential biomarker ...
