Quasi total double Roman domination stability 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 [Formula: see text] if [Formula: see text], then the vertex v must have at least two neighbors ...

Domination parameters with number 2: interrelations and algorithmic consequences

open access: yes, 2016
In this paper, we study the most basic domination invariants in graphs, in which number 2 is intrinsic part of their definitions. We classify them upon three criteria, two of which give the following previously studied invariants: the weak $2$-domination

Occurrence, morphology and growth of understory saplings in Swedish forests [PDF]

open access: yes, 2004
Growing demands for a multipurpose forestry leads to increased use of silvicultural systems that avoid clear-cutting. Regeneration in such systems is based on establishment and ingrowth of new seedlings under a more or less closed canopy.

Birth, survival and death of languages by Monte Carlo simulation

open access: yes, 2007
Simulations of physicists for the competition between adult languages since 2003 are reviewed. How many languages are spoken by how many people? How many languages are contained in various language families?

On the Total Version of Triple Roman Domination in Graphs

open access: yesMathematics
In this paper, we describe the study of total triple Roman domination. Total triple Roman domination is an assignment of labels from {0,1,2,3,4} to the vertices of a graph such that every vertex is protected by at least three units either on itself or ...

Optical scatter of quantum noise filter cavity optics

open access: yes, 2015
Optical cavities to filter squeezed light for quantum noise reduction require optics with very low scattering losses. We report on measured light scattering from two super-polished fused silica optics before and after applying highly-reflective ion-beam ...

Feasibility Studies of the Diffractive Bremsstrahlung Measurement at the LHC

open access: yes, 2016
Feasibility studies of an observation of the exclusive diffractive bremsstrahlung in proton-proton scattering at the LHC are reported. A simplified approach to the photon and the scattered proton energy reconstruction is used. The background influence is

The First Year at LHC: Diffractive Physics

open access: yes, 2005
At the LHC, diffractive physics will be explored by the dedicated experiment TOTEM whose Technical Design Report has been approved in Summer 2004. The experimental programme will be carried out partly in TOTEM standalone mode for purely forward phenomena

Properties of excitations in systems with a spinor Bose-Einstein condensate

open access: yes, 1999
General theory in case of homogenous Bose-Einstein condensed systems with spinor condensate is presented for the correlation functions of density and spin fluctuations and for the one-particle propagators as well.
