Traveling waves of DDEs with rational nonlinearity
(De Gruyter, 2016-08)It has been found that the dynamical behavior of many complex physical systems can be properly described by nonlinear DDEs. However, in the related literature, research focusing on such equations with rational nonlinearity ... -
Reidemeister torsion and orientable punctured surfaces
(Korean Mathematical Society, 2018)Let Σg,n,b denote the orientable surface obtained from the closed orientable surface Σg of genus g ≥ 2 by deleting the interior of n ≥ 1 distinct topological disks and b ≥ 1 points. Using the notion of symplectic chain ... -
A1-L10 phase boundaries and anisotropy via multiple-order-parameter theory for an fcc alloy
(European Mathematical Society Publishing House, 2003)The dependence of thermodynamic properties of planar interphase boundaries (IPBs) and antiphase boundaries (APBs) in a binary alloy on an fcc lattice is studied as a function of their orientation. Using a recently developed ... -
Erratum 2: Search for dark matter and unparticles in events with a Z boson and missing transverse momentum in proton-proton collisions at √s=13 TeV
(Springer, 2018-01)In the original paper, figure 10 was incorrect. The correct figure is shown below. Additionally, the unparticle entries in table 3, as well as figure 4 and 5 were labelled with incorrect values of ΛU. The entries correctly ... -
Search for resonant and nonresonant Higgs boson pair production in the b b ¯final state in proton-proton collisions at √s=13 TeV
(Springer, 2018-01)Searches for resonant and nonresonant pair-produced Higgs bosons (HH) decaying respectively into , through either W or Z bosons, and b b ¯ are presented. The analyses are based on a sample of proton-proton collisions at ... -
Pseudorapidity distributions of charged hadrons in proton-lead collisions at √sNN=5.02 and 8.16 TeV
(Springer, 2018-01)The pseudorapidity distributions of charged hadrons in proton-lead collisions at nucleon-nucleon center-of-mass energies sNN=5.02 and 8.16 TeV are presented. The measurements are based on data samples collected by the CMS ... -
Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
(American Physical Society, 2018-01)A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance pTmiss in transverse momentum. The data were collected ... -
Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at √s=13 TeV
(Springer, 2018-01)A search for narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in proton-proton collisions at s=13 TeV with the CMS detector at the LHC, corresponding to an ... -
Combination of inclusive and differential tt¯ charge asymmetry measurements using ATLAS and CMS data at √s = 7 and 8 TeV
(Springer, 2018-01)This paper presents combinations of inclusive and differential measurements of the charge asymmetry (AC) in top quark pair (tt) events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC ... -
On scattering from the one-dimensional multiple Dirac delta potentials
(Institute of Physics Publishing, 2018-03)In this paper, we propose a pedagogical presentation of the Lippmann-Schwinger equation as a powerful tool, so as to obtain important scattering information. In particular, we consider a one-dimensional system with a ... -
Pseudo-multi-scale functions for the stabilization of convection-diffusion equations on rectangular grids
(Begell House, 2013)We propose a finite element method of Petrov-Galerkin type for a singularly perturbed convection diffusion problem on a discretization consisting of rectangular elements. The method is based on enriching the finite-element ... -
Convergence analysis and numerical solution of the Benjamin-Bona-Mahony equation by Lie-Trotter splitting
(TUBITAK, 2018)In this paper, an operator splitting method is used to analyze nonlinear Benjamin-Bona-Mahony-type equations. We split the equation into an unbounded linear part and a bounded nonlinear part and then Lie-Trotter splitting ... -
Exactly solvable Hermite, Laguerre, and Jacobi type quantum parametric oscillators
(American Institute of Physics, 2016-12)We introduce exactly solvable quantum parametric oscillators, which are generalizations of the quantum problems related with the classical orthogonal polynomials of Hermite, Laguerre, and Jacobi type, introduced in the ... -
Analytic investigation of a reaction-Diffusion brusselator model with the time-space fractional derivative
(De Gruyter, 2014-04)It is well known that many models in nonlinear science are described by fractional differential equations in which an unknown function appears under the operation of a derivative of fractional order. In this study, we ... -
On pseudo semisimple rings
(World Scientific Publishing, 2013-03)A necessary and sufficient condition is obtained for a right pseudo semisimple ring to be left pseudo semisimple. It is proved that a right pseudo semisimple ring is an internal exchange ring. It is also proved that a right ... -
Rings over which flat covers of simple modules are projective
(World Scientific Publishing, 2012-06)Let R be a ring with identity. We prove that, the flat cover of any simple right R-module is projective if and only if R is semilocal and J(R) is cotorsion if and only if R is semilocal and any indecomposable flat right ... -
Motion of vortices outside a cylinder
(American Institute of Physics Publishing, 2010-12)The problem of motion of the vortices around an oscillating cylinder in the presence of a uniform flow is considered. The Hamiltonian for vortex motion for the case with no uniform flow and stationary cylinder is constructed, ... -
Remark on:"Exp-function method for the exact solutions of fifth order KdV equation and modified Burgers equation" [Appl. Math. Comput. (2009) doi:10.1016/j.amc.2009.07.009]

Co-coatomically supplemented modules
(Springer, 2017-12)It is shown that if a submodule N of M is co-coatomically supplemented and M/N has no maximal submodule, then M is a co-coatomically supplemented module. If a module M is co-coatomically supplemented, then every finitely ...
