The interface between a ferro-/ferrimagnetic insulator and normal metal can support spin currents polarized collinear with perpendicular to the magnetization direction. flow of angular momentum direction ("transverse" current) takes place via torque pumping. ("longitudinal" requires excitation magnons. In this article we extend existing theory longitudinal transport [Bender Tserkovnyak, Phys. R...

Abstract We generate a spatiotemporal optical vortex (STOV) with tunable orbital angular momentum (OAM) orientation by simple lens system. utilize cylindrical system, which is an astigmatic mode converter, to add longitudinal tilt the purely transverse OAM in arbitrary direction. The amount of adjusting and thus direction continuously adjustable. STOVs adjustable directions have been verified t...

Unsignalized intersection cooperation of connected and automated vehicles (CAVs) is able to eliminate green time loss signalized intersections improve traffic efficiency. Most the existing research on unsignalized considers fixed lane direction, where only specific turning behavior allowed each lane. Given that volume proportion with different expectation may change time, direction lead ineffic...

Noninvasive measurements of myocardial strain and strain rate by speckle tracking echocardiography correlate to cardiac contractile state but also to load, which may weaken their value as indices of inotropy. In a porcine model, we investigated the influence of acute dynamic preload reductions on left ventricular strain and strain rate and their relation to the pressure-conductance catheter-der...

This study used a multiwave design to examine the short-term longitudinal and bidirectional associations between depressive symptoms and peer relationship qualities among a sample of early to middle adolescents (N = 350, 6th-10th graders). Youth completed self-report measures of relationship quality and depressive symptoms at three time points spaced about 5 weeks apart. Results indicated that ...

For second harmonic generation in two-dimensional wave-guiding structures composed of segments that are invariant in the longitudinal direction, we develop an efficient numerical method based on the Dirichlet-to-Neumann (DtN) maps of the segments and a marching scheme using two operators and two functions. A Chebyshev collocation method is used to discretize the longitudinal variable for comput...

Unidirectional fiber-reinforced composites are often observed to fail in a longitudinal splitting mode in the fiber direction under far-field compressive loading with weak lateral confinement. An energy-based model is developed based on the principle of minimum potential energy and the evaluation of effective properties to obtain an analytical approximation to the critical stress for longitudin...

The possibility of tailoring the guidance properties of optical fibers along the same direction as the evolution of the optical field allows to explore new directions in nonlinear fiber optics. The new degree of freedom offered by axiallyvarying optical fibers enables to revisit well-established nonlinear phenomena, and even to discover novel short pulse nonlinear dynamics. Here we study the im...

We measured the dispersion of the graphite optical phonons in the in-plane Brillouin zone by inelastic x-ray scattering. The longitudinal and transverse optical branches cross along the Gamma-K as well as the Gamma-M direction. The dispersion of the optical phonons was, in general, stronger than expected from the literature. At the K point the transverse optical mode has a minimum and is only a...

A study is made of the influence of the longitudinal magnetic field and density inhomogeneity on the supersonic shear flow instability at the magnetospheric tail boundary. It is shown that the most unstable are slow oblique (3D) disturbances, with a phase velocity approaching at a sufficiently large angle (with respect to the flow direction) the magnetosonic velocity. Their growth rate and spec...
