We compare the physical potential V(D)(R) of an external quark-antiquark pair in the representation D of SU(N), to the color-Coulomb potential V(coul)(R) which is the instantaneous part of the 44-component: of the gluon propagator in Coulomb-gauge D44(x-->,t)=V(coul)(|x-->|)delta(t)+(noninstantaneous). We show that if V(D)(R) is confining, lim(V(D)(R)=+ infinity, as is believed to hold in the a...

The assumption of the Convergence–Confinement Method (CCM) is analysis interaction behavior support and ground a deep circular tunnel under an isotropic stress field. Aiming to improve this method, paper proposes discussion on influence overburden depth anisotropy. To consider effect, reaction in different depths due advancing excavation investigated. Under anisotropic conditions, analytical so...

From the frontier of this paper, unless specified something else, let it be agreed that all groups into consideration are p-primary abelian for some arbitrary but fixed prime p written additively as is the custom when dealing with abelian group theory. The present short note is a contribution to a recent flurry of our results in [6]. Standardly, all notions and notations are essentially the sam...

For the past several years, there has been a lot of work in modelling complex simulations pertaining to motion of gases. In the work of [Fedkiw et al., 2001], a new approach to numerically simulate smoke was developed which incorporates the model proposed by Steinhoff and Underhill [Steinhoff and Underhill, 1994] known as “vorticity confinement”. Passive advection of smoke particles is consider...

proton transfer (pt) and methyl group transfer (mgt) occurring in small biomimetic systems, formamide-formamidic acid (fa-fi), and n-formyl-n-methylformamide-(e)-methyl n-formylformimidate (nmfa-nmfi) are investigated in the gas phase and in single-walled carbon nanotubes by using the density functional theory and the oniom approach. it is shown that pt reaction is disfavoured in single-walled ...

reliable stress-strain behavior of concrete is necessary particularly when a member is subjected to combine bending and axial load and confinement effects should be accounted for. a unified theory for confinement of circular hollow sections is proposed herein, that can be extended to the case of solid and noncircular sections. the main aim of the model is to trace step-by-step the evolution of ...

We investigate experimentally the behavior of self-propelled water-in-oil droplets, confined in capillaries different square and circular cross-sections. The droplet's activity comes from formation swollen micelles at its interface. In straight velocity droplet decreases with increasing confinement. However very high confinement, converges toward a non-zero value, so that even long droplets swi...

A brief and biased overview of the phenomenon of confinement in QCD is presented in three parts: (1) the definition of confinement, (2) properties of confinement, (3) ideas of confinement. The second part chiefly consists of a brief review of recent lattice computations related to confinement while the third summarizes some of the current analytical approaches to understanding confinement. Thes...

We consider systems of n parallel edge dislocations in a single slip system, represented by points in a two-dimensional domain; the elastic medium is modelled as a continuum. We formulate the energy of this system in terms of the empirical measure of the dislocations, and prove several convergence results in the limit n → ∞. The main aim of the paper is to study the convergence of the evolution...
