Current driven domain wall motion in curved Heavy Metal/Ferrimagnetic/Oxide multilayer strips is investigated using systematic micromagnetic simulations which account for spin-orbit coupling phenomena. Domain velocity and characteristic relaxation times are studied as functions of the geometry, curvature width strip, at out angular momentum compensation. Results show that walls can propagate fa...
In this paper, the precoding-based peak-to-average power ratio (PAPR) reduction methods are studied for massive multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system in angular domain. The expectation maximization generalized approximate message passing algorithm and proposed optimized alternating direction method of multipliers (OADMM) scheme adopted he...
We develop a theory for the dynamics of magnon on top domain wall in ferromagnetic nanotube. Due to geometry sample, walls are classified by Skyrmion charge which counts winding number magnetic textures. The with non-zero generates an emergent field magnons, exerts Lorentz force moving magnons and thereby deflects their trajectories. This deflection is manifested as generation finite orbital an...
a new mechanical cultivator was proposed for mechanical weeding in part one. the precise point method was used to geometric design of this new cultivator. the aim of this research is selecting the suitable mechanism of the studied mechanisms in part one. the velocity and acceleration of links (kinematic) is the base of dynamic analysis of the systems. the variation of velocity, acceleration and...
During ultrafast demagnetization of a magnetically ordered solid, angular momentum has to be transferred between the spins, electrons, and phonons in the system on femto- and picosecond timescales. Although the intrinsic spin-transfer mechanisms are intensely debated, additional extrinsic mechanisms arising due to nanoscale heterogeneity have only recently entered the discussion. Here we use fe...
Molecular anions possessing excess internal vibrational and/or rotational energy can eject their “extra” electron through radiationless transitions involving non-Born-Oppenheimer coupling. In such processes, there is an interplay between the nuclear and electronic motions that allows energy to be transferred from the former to the latter and that permits momentum and/or angular momentum to also...
This paper presents an algorithm based on a continuous framework for a posteriori angular and translational assignment in three-dimensional electron microscopy (3DEM) of single particles. Our algorithm can be used advantageously to refine the assignment of standard quantized-parameter methods by registering the images to a reference 3D particle model. We achieve the registration by employing a ...
