Diffractive Bremsstrahlung at High-$\beta^\star$ LHC Case Study

open access: yes, 2016
Feasibility studies of the measurement of the exclusive diffractive bremsstrahlung cross-section in proton-proton scattering at the centre of mass energy of 13 TeV at the LHC are reported. Present studies were performed for the low luminosity LHC running

Domination Problems in Nowhere-Dense Classes [PDF]

open access: yes, 2009
We investigate the parameterized complexity of generalisations and variations of the dominating set problem on classes of graphs that are nowhere dense.

Data Reductions and Combinatorial Bounds for Improved Approximation Algorithms [PDF]

open access: yes, 2014
Kernelization algorithms in the context of Parameterized Complexity are often based on a combination of reduction rules and combinatorial insights. We will expose in this paper a similar strategy for obtaining polynomial-time approximation algorithms ...

Towards optimal explicit time-stepping schemes for the gyrokinetic equations

open access: yes, 2014
The nonlinear gyrokinetic equations describe plasma turbulence in laboratory and astrophysical plasmas. To solve these equations, massively parallel codes have been developed and run on present-day supercomputers. This paper describes measures to improve

Roman Domination in Complementary Prism Graphs [PDF]

open access: yes, 2012
A Roman domination function on a complementary prism graph GGc is a function f : V [ V c ! {0, 1, 2} such that every vertex with label 0 has a neighbor with label 2. The Roman domination number R(GGc) of a graph G = (V,E) is the minimum of Px2V [V c f(x)

Fermi sea term in the relativistic linear muffin-tin-orbital transport theory for random alloys

open access: yes, 2014
We present a formulation of the so-called Fermi sea contribution to the conductivity tensor of spin-polarized random alloys within the fully relativistic tight-binding linear muffin-tin-orbital (TB-LMTO) method and the coherent potential approximation ...

Method of variational calculation of influence of the propulsion plants of forestry machines upon the frozen and thawing soil grounds [PDF]

open access: yes, 2019
The forests, which grow in the conditions of complete expansion of the perpetually frozen ground, are unique forests in accordance with their taxational characteristics, quality indicators of the felled timber, and the ecological functions, which these ...

Exclusive diffractive resonance production in proton-proton collisions at high energies

open access: yes, 2017
A model for exclusive diffractive resonance production in proton-proton collisions at high energies is presented. This model is able to predict double differential distributions with respect to the mass and the transverse momentum of the produced ...

Thermal conductivity via magnetic excitations in spin-chain materials

open access: yes, 2006
We discuss the recent progress and the current status of experimental investigations of spin-mediated energy transport in spin-chain and spin-ladder materials with antiferromagnetic coupling.

Quasi total double Roman domination in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
A quasi total double Roman dominating function (QTDRD-function) on a graph [Formula: see text] is a function [Formula: see text] having the property that (i) if f(v) = 0, then vertex v must have at least two neighbors assigned 2 under f or one neighbor w
