The interstellar medium and solar wind is permeated by a magnetic field that renders magnetohydrodynamic turbulence anisotropic. In the classic work of Iroshnikov @Astron. Zh. 40, 742 ~1963!# and Kraichnan @Phys. Fluids 8, 1385 ~1965!#, it is assumed that the turbulence is isotropic, and an inertial range energy spectrum that scales as k is deduced based on the nonlinear interaction of Alfvén w...

An understanding of the mechanisms producing dimensional changes in reactor structural materials is of major importance for reactor design purposes. When a crystalline material is irradiated by energetic neutrons, ions or electrons, damage is produced in the form of atomic displacements, which subsequently evolve into a supersaturation of freely migrating vacancies and interstitials * in the te...

We apply generalized ellipsometry, well-known to be sensitive to the optical properties of anisotropic materials, to determine the amount of fibronectin protein that adsorbs onto a Ti slanted columnar thin film from solution. We find that the anisotropic optical properties of the thin film change upon organic adsorption. ...

An isotropic scaling formulation is evaluated for transient radiative transfer in a one-dimensional planar slab subject to collimated and/or diffuse irradiation. The Monte Carlo method is used to implement the equivalent scattering and exact simulations of the transient short-pulse radiation transport through forward and backward anisotropic scattering planar media. The scaled equivalent isotro...

We find the Lax pair for a system of reduced Maxwell–Bloch equations that describes the propagation of twocomponent extremely short electromagnetic pulses through the medium containing two-level quantum particles with arbitrary dipole moments.

The paper is devoted to investigation of Bragg diffraction of light by ultrasound propagating in media possessing strong anisotropy of acoustic properties. It is shown that acoustic anisotropy of crystals influences on the process of light and sound interaction. In case of Bragg regime of acousto-optic interaction, intensity of diffracted light and frequency bandwidths of diffraction in the cry...

Elastic wave propagation and scattering in heterogeneous, anisotropic media: Textured polycrystalline materials" (1999). Faculty Publications from Nebraska Center for Materials and Nanoscience. Paper 60. The propagation of elastic waves through heterogeneous, anisotropic media is considered. Appropriate ensemble averaging of the elastic wave equation leads to the Dyson equation which governs th...

In this paper, a new inversion scheme for surface-wave velocities in a slightly anisotropic medium will be presented, revisiting the inversion method performed by Corchete and Badal (2004). Tecnociencia 6(2), 23–41). An extension of the Smith–Dahlen formulation will be examined and revised. The surfacewave propagation in a slightly anisotropic medium will be considered, and the inversion of the...

Some progenitor models of gamma-ray bursts (GRBs) (e.g., collapsars) may produce anisotropic jets in which the energy per unit solid angle is a power-law function of the angle (∝ θ −k). We calculate light curves and spectra for GRB afterglows when such jets expand either in the interstellar medium or in the wind medium. In particular, we take into account two kinds of wind: one (n ∝ r −3/2) pos...
