Relationship of isokinetic torque to isometric torque

Journal of Orthopaedic Research, 1983
AbstractIsokinetic muscle testing has become an increasingly popular method for measuring muscle performance. However, the relationship of isokinetic strength measurements to static strength measurements remains unclear. The relationship between maximal isokinetic and maximal isometric torque was investigated at angular velocities of 24, 48, 96, and ...

Magnetization switching by spin-orbit torque in an antiferromagnet-ferromagnet bilayer system.

Nature Materials, 2015
Spin-orbit torque (SOT)-induced magnetization switching shows promise for realizing ultrafast and reliable spintronics devices. Bipolar switching of the perpendicular magnetization by the SOT is achieved under an in-plane magnetic field collinear with an
