Influence of through-flow on linear pattern formation properties in binary mixture convection

, 1996
We investigate how a horizontal plane Poiseuille shear flow changes linear convection properties in binary fluid layers heated from below. The full linear field equations are solved with a shooting method for realistic top and bottom boundary conditions.

Approximate transmission coefficients in heavy ion fusion

, 2017
In this paper we revisit the one-dimensional tunnelling problem. We consider different approximations for the transmission through the Coulomb barrier in heavy ion collisions at near-barrier energies. First, we discuss approximations of the barrier shape

Accurate "superluminal" transmission via entanglement, superoscillations and quasi-Dirac distributions

, 2009
We analyse a system in which, due to entanglement between the spin and spatial degrees of freedom, the reduced transmitted state has the shape of the freely propagating pulse translated in the complex co-ordinate plane.

Yang-Lee Zeros of the Ising model on Random Graphs of Non Planar Topology [PDF]

, 2000
We obtain in a closed form the 1/N^2 contribution to the free energy of the two Hermitian N\times N random matrix model with non symmetric quartic potential. From this result, we calculate numerically the Yang-Lee zeros of the 2D Ising model on dynamical

Approximation by complex Stancu Beta operators of second kind in semidisks

Journal of Numerical Analysis and Approximation Theory, 2013
In this paper, the exact order of simultaneous approximation and Voronovskaja kind results with quantitative estimate for the complex Stancu Beta operator of second kind attached to analytic functions of exponential growth in semidisks of the right

High-energy photoemission final states beyond the free-electron approximation

Nature Communications, 2023
Three-dimensional (3D) electronic band structure is fundamental for understanding a vast diversity of physical phenomena in solid-state systems, including topological phases, interlayer interactions in van der Waals materials, dimensionality-driven phase

On The Pomeron at Large 't Hooft Coupling

, 2010
We begin the process of unitarizing the Pomeron at large 't Hooft coupling. We do so first in the conformal regime, which applies to good accuracy to a number of real and toy problems in QCD.

A Note on Rational Approximation with Respect to Metrizable Compactifications of the Plane

Extracta Mathematicae, 2016
In the present note we examine possible extensions of Runge, Mergelyan and Arakelian Theorems, when the uniform approximation is meant with respect to the metric ρ of a metrizable compactification (S, ρ) of the complex plane C.

Asymptotic analysis of flow near a glacier terminus

Journal of Glaciology, 2018
The non-linearly viscous ice flow in the vicinity of a glacier terminus, an observation region, depends crucially on the upstream flow as well as on the local surface and bed conditions.
