We report a soft x-ray resonant magnetic scattering study of the spin configuration in multiferroic thin films ${\mathrm{Co}}_{0.975}{\mathrm{Ge}}_{0.025}{\mathrm{Cr}}_{2}{\mathrm{O}}_{4}$ (Ge-CCO) and ${\mathrm{CoCr}}_{2}{\mathrm{O}}_{4}$ (CCO) under low high fields from 0.2 to 6.5 T. A characterization Ge-CCO at field was performed, results were compared with those pure CCO. The ferrimagnetic...

Convective motions in the deep layers of solar convection zone are affected by rotation, making convective heat transport latitude-dependent, but this is not case top near surface. We use thermal wind balance condition deeper to estimate pole–equator temperature difference. Surface observations difference can be used for estimating depth near-surface layer within which rotation. If we require t...

We present measurements of the rotation rates of individual starspots on the rapidly rotating young K0 dwarf AB Doradus, at six epochs between 1988 December and 1996 December. The equatorial rotation period of the star decreased from 0.5137 to 0.5129 days between 1988 December and 1992 January. It then increased steadily, attaining a value of 0.5133 days by 1996 December. The latitude dependenc...

The statistical behavior of a nonlinear system described by a mapping with phase rotation is studied. We use the Kolmogorov-Chapman equations for the multi-time probability distribution functions for investigation of dynamics under the external noise perturbations. We find a stationary solution in the long-time limit as a power series around a state with complete phase randomization (”phase mix...

In addition to the separable solutions of the rotation equation, relating the perturbations of the metric tensor to the angular velocity of the matter on the brane, we show that the rotation equation admits solutions for a special class of non-separable angular velocity of the matter distribution on the brane. The general solution of the rotation equation is expressed in terms of an arbitrary, ...

Humans perform vertical and horizontal arm motions with different temporal patterns. The specific velocity profiles are chosen by the central nervous system by integrating the gravitational force field to minimize energy expenditure. However, what happens when a visuomotor rotation is applied, so that a motion performed in the horizontal plane is perceived as vertical? We investigated the dynam...

We present a B-spline-based complex rotation (BSCR) method with spin-dependent interaction for the study of atomic photoionization leading to multiple ionization channels dominated by doubly excited resonances for two-electron and divalent atoms. The degree of mixing between different spin states and between the bound and continuum components of the state function of the resonance state can be ...

On the main sequence, low-mass and solar-like stars are observed to spin-down over time, magnetized stellar winds thought be predominantly responsible for this significant angular momentum loss. Previous studies have demonstrated that wind torque can predicted via formulations dependent on properties, such as magnetic field strength geometry, radius mass, mass-loss rate, rotation rate. Although...
