These approaches, which build on the original gradient ascent pulse engineering algorithm, remain computationally intensive because of the need to calculate matrix exponentials for each time step in the control pulse. In this study, we discuss how the propagators for each time step can be ...
Then gradient ascent is used to take steps in the input space to synthesize inputs that cause the highest activation for this unit (gradient ascent is also used by Nguyen et al. [38] for the same purpose). The process stops when an optimal input is obtained that can maximally stimulate ...
Thus if χ > χw, the magnetic force acts in the direction of the steepest ascent of the energy density scalar field. If the magnetic field gradient must immobilize MNPs by capturing them from a flowing liquid, this force needs to overcome the hydrodynamic drag force acting on the magnetic ...
