The nearly-optimal Petrov-Galerkin method for convection-diffusion problems
(Elsevier, 2003-06)The nearly-optimal Petrov-Galerkin (NOPG) method is employed to improve finite element computation of convection-dominated transport phenomena. The design of the NOPG method for convection-diffusion is based on consideration ... -
Neat-flat modules
(Taylor & Francis, 2016-01)Let R be a ring. A right R-module M is said to be neat-flat if the kernel of any epimorphism Y → M is neat in Y, i.e., the induced map Hom(S, Y) → Hom(S, M) is surjective for any simple right R-module S. Neat-flat right ... -
A new Boson with a mass of 125 GeV observed with the CMS experiment at the large hadron collider
(American Association for the Advancement of Science, 2012-12)The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would ... -
New casimir energy calculations
(World Scientific Publishing, 2007)New Casimir energy results for massless scalar field in some 3 -dimensional cavities are presented. We attempted to discuss the correlation between the sign and the magnitude of the energy and the shape of the cavities. ... -
A new dynamical model of brainstorming: Linear, nonlinear, continuous (simultaneous) and impulsive (sequential) cases
(Elsevier, 2009-08)In this paper, we extended the linear dynamical model of [Brown, V., Paulus, P. B. (1996). A simple dynamic model of social factors in group brainstorming. Small Group Research, 27, 91-114] on two accounts. First, we ... -
New mathematical model for finding minimum vertex cut set
(IEEE, 2012)In this paper, we consider the vertex separator problem. Given an undirected graph G, the vertex separator problem consists in identifying a minimum number of vertex set whose removal disconnects G. We present a new ... -
The Newton-Wigner localization concept and noncommutative space
(Kluwer Academic Publishers, 2005)In the formulation of the Newton-Wigner postulates for the relativistic localized states the hypothesis of commutativity of the position operator components is silently accepted as an evident fact. In the present work it ... -
Noetherian and Artinian lattices
(Hindawi Publishing Corporation, 2012)It is proved that if L is a complete modular lattice which is compactly generated, then Rad(L)/0 is Artinian if, and only if for every small element a of L, the sublattice a/0 is Artinian if, and only if L satisfies DCC ... -
Nondegeneracy of the ground state for nonrelativistic Lee model
(American Institute of Physics Publising, 2014-08)In the present work, we first briefly sketch the construction of the nonrelativistic Lee model on Riemannian manifolds, introduced in our previous works. In this approach, the renormalized resolvent of the system is expressed ... -
Nonlinear integral equations for Bernoulli's free boundary value problem in three dimensions
(Elsevier, 2017-12)In this paper we present a numerical solution method for the Bernoulli free boundary value problem for the Laplace equation in three dimensions. We extend a nonlinear integral equation approach for the free boundary ... -
Nonlinear schrödinger equations on the half-line with nonlinear boundary conditions
(Texas State University, 2016-08)In this article, we study the initial boundary value problem for nonlinear Schrödinger equations on the half-line with nonlinear boundary conditions ux(0, t) + λ|u(0, t)|ru(0, t) = 0, λ ∈ ℝ − {0}, r > 0. We discuss the ... -
A note on the (G′/G)-expansion method again
(Elsevier, 2010-09)We report an observation on two recent analytic methods; the (G′/G)-expansion method and the simplest equation method. © 2010 Elsevier Inc. All rights reserved. -
Observation of a new boson with mass near 125 GeV in pp collisions at √=7 and 8 TeV
(Springer, 2013)A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample ... -
Observation of charge-dependent azimuthal correlations in p-Pb collisions and its implication for the search for the chiral magnetic effect
(American Physical Society, 2017-03)Charge-dependent azimuthal particle correlations with respect to the second-order event plane in p-Pb and PbPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV have been studied with the CMS experiment at ... -
Observation of sequential Υ suppression in PbPb collisions
(American Physical Society, 2012-11)The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of 150μb -1 ... -
Observation of the rare B0s→μ+μ- decay from the combined analysis of CMS and LHCb data
(Nature Publishing Group, 2015-06)The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested ... -
Observation of top quark pairs produced in association with a vector boson in pp collisions at √s = 8 TeV
(Springer, 2016)Measurements of the cross sections for top quark pairs produced in association with a W or Z boson are presented, using 8 TeV pp collision data corresponding to an integrated luminosity of 19.5 fb-1, collected by the CMS ... -
