We analyze the thermal convection thresholds and linear characteristics of the primary 1 and secondary instabilities for viscoelastic fluids saturating a porous horizontal layer heated from 2 below by a constant flux. Galerkin method is used to solve the eigenvalue problem by taking 3 into account the elasticity of the fluid, the ratio between the viscosity of the solvent and the total 4 viscos...

This talk outlines the derivation of a high-energy, transverse momentum cutoff , solution of QCD in which the Regge pole and " single gluon " properties of the pomeron are directly related to the confinement and chiral symmetry breaking properties of the hadron spectrum. In first approximation, the pomeron is a single reggeized gluon plus a " wee parton " component that compensates for the colo...

The Vlasov-Maxwell equations are used to investigate properties of the electron-ion two-stream instability for a continuous, high-intensity ion beam propagating in the zdirection with directed axial velocity Vb = βbc through a background population of (stationary) electrons. The analysis is carried out for arbitrary beam intensity, consistent with transverse confinement of the beam particles, a...

This is an attempt to summarize the talks given at the session on Deconfinement in the Conference “Quark Confinement and hadron spectrum”. This talk covers the following topics: Elliptic flow and evidence of nearly perfect fluid of the created matter; High Transverse momentum production, propagation of jets and energy loss; Heavy quarqonia in dense QCD matter; Phase transition, Multiplicity flu...

By carrying out extensive lattice regularized diffusion Monte Carlo calculations, we study the spin and density dependence of the ground state energy for a quasi-one-dimensional electron gas, with harmonic transverse confinement and long-range 1/r interactions. We present a parametrization of the exchangecorrelation energy suitable for spin density functional calculations, which fulfills exact ...

Steel embedded in cement mortar in the uniaxial compressive stress direction was found to decrease by 80% the compressive longitudinal strain at a given stress and increase by 300% the tensile transverse strain at a given longitudinal strain. The former effect is due to longitudinal confinement of mortar by steel. The latter is due to debonding at the steel-mortar interface. © 1999 Elsevier Sci...

We investigate the dual superconductor mechanism of confinement for pure SU(2) lattice gauge theory in the maximally abelian gauge. We focus on the the dual Meissner effect. We find that the transverse distribution of the longitudinal chromoelectric field due to a static quark-antiquark pair satisfies the dual London equation. Moreover we show that the size of the flux tube scales according to ...

Parton distribution functions, which represent the flavor and spin structure of the nucleon, provide invaluable information in illuminating quantum chromodynamics in the confinement region. Among various processes that measure such parton distribution functions, semi-inclusive deep inelastic scattering is regarded as one of the golden channels to access transverse momentum dependent parton dist...

In this paper we propose a novel method of adding turbulence to low-res. smoke simulation. We consider the physical properties of such low-res. simulation and add turbulence only to the appropriate position where the value of the energy cascade ratio is judged as physically correct. Our method can prevent noise in the whole region of fluid surfaces which appeared with previous methods. We also ...
