We calculate photon production from a quark-gluon plasma which is anisotropic in momentum space including the Compton scattering, q(q̄) g → q(q̄) γ, and annihilation, q q̄ → g γ, processes. We show that for a quark-gluon plasma which has an oblate momentum-space anisotropy, 〈p2L〉 < 〈p 2 T 〉, the photon production rate has an angular dependence which is peaked transverse to the beam line. We propos...

1. Abstract Motivated by field measurements of aquifer hydraulic conductivity (K), recent tech5 niques were developed to construct anisotropic fractal random fields, in which the scaling, 6 or self-similarity parameter, varies with direction and is defined by a matrix. Ensemble 7 numerical results are analyzed for solute transport through these 2-D “operator-scaling” 8 fractional Brownian motio...

The linear governing equations of a transversely isotropic microstretch elastic solid medium are formulated and solved for surface wave solutions. The appropriate solutions satisfying the radiation conditions are applied to the required boundary conditions at the free surface of the halfspace of the medium. A frequency equation is obtained for Rayleigh surface wave in the medium. The non-dimens...

In this paper, a finite element (FE) based model for the viscous and incompressible fluid flow through a regular porous media composed of rigid (immobile) particles/fibers is considered, and an analytical-numerical approach is employed to calculate the associated transverse permeability. The effects of an isotropy, i.e., the particle shape or orientation, as well as porosity, i.e., the volume f...

Child cortical bone tissue is rarely studied because of the difficulty of obtaining samples. Yet the preparation and ultrasonic characterization of the small samples available, while challenging, is one of the most promising ways of obtaining information on the mechanical behavior of non-pathological children’s bone. We investigated children’s cortical bone obtained from chirurgical waste. Stif...

Three-dimensional modeling of upper-mantle anelastic structure reveals that thermal upwellings associated with the two superplumes, imaged by seismic elastic tomography at the base of the mantle, persist through the upper-mantle transition zone and are deflected horizontally beneath the lithosphere. This explains the unique transverse shear wave isotropy in the central Pacific. We infer that th...
