Arbitrary d–q current sharing in three-phase winding sets of multi-phase machines
The Journal of Engineering, 2019 This study proposes a technique for arbitrary current sharing between winding sets of any multiple three-phase machine by using a decoupled control in two-dimensional orthogonal vector space decomposition subspaces.

Controlling the state of quantum spins with electric currents [PDF]
Nature Physics, 2010 It is well known that a spin-polarized current can be used to manipulate the orientation of nanometre-scale magnets. This ability has now been extended to control the spin orientation of magnetic atoms adsorbed on a surface. A current of spin-polarized electrons senses and controls the magnetic state of nanostructured materials1.
