The AblowitzLadik lattice system by means of the extended (G′ / G)expansion method
(Elsevier, 201007)We analyzed the AblowitzLadik lattice system by using the extended (G′ / G)expansion method. Further discrete soliton and periodic wave solutions with more arbitrary parameters are obtained. We observed that some previously ... 
Absolutely spure modules and neatflat modules
(Taylor & Francis, 201502)Let R be a ring with an identity element. We prove that R is right Kasch if and only if injective hull of every simple right Rmodules is neatflat if and only if every absolutely pure right Rmodule is neatflat. A ... 
An analytic approach to a class of fractional differentialdifference equations of rational type via symbolic computation
(Wiley, 201501)Fractional derivatives are powerful tools in solving the problems of science and engineering. In this paper, an analytical algorithm for solving fractional differentialdifference equations in the sense of Jumarie's modified ... 
Analytic investigation of a reactionDiffusion brusselator model with the timespace fractional derivative
(De Gruyter, 201404)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 ... 
Analytic investigation of the (2 + 1)dimensional Schwarzian Korteweg–de Vries equation for traveling wave solutions
(Elsevier BV., 20110215)By means of the two distinct methods, the Expfunction method and the extended (G0/G)expansion method, we successfully performed an analytic study on the (2 + 1)dimensional Schwarzian Korteweg–de Vries equation. We ... 
Analytic solutions to nonlinear differentialdifference equations by means of the extended (G′/G)expansion method
(IOP Publishing, 201010)In this paper, a discrete extension of the (G′/G)expansion method is applied to a relativistic Toda lattice system and a discrete nonlinear Schrödinger equation in order to obtain discrete traveling wave solutions. Closed ... 
Angular analysis of the decay B0→K*0μ+μ from pp collisions at s=8 TeV
(Elsevier, 201602)The angular distributions and the differential branching fraction of the decay B0→K*(892)0μ+μ are studied using data corresponding to an integrated luminosity of 20.5 fb1 collected with the CMS detector at the LHC in pp ... 
Angular coefficients of Z bosons produced in pp collisions at (root) S=8 TeV and decaying to μ+μ as a function of transverse momentum and rapidity
(Elsevier, 201511)Measurements of the five most significant angular coefficients, A0 through A4, for Z bosons produced in pp collisions at s=8 TeV and decaying to μ+μ are presented as a function of the transverse momentum and rapidity of ... 
Application of the division theorem to nonlinear physical models for constructing traveling waves
(Politechnica University of Bucharest, 2013)We extend the socalled first integral method, which is based on the division theorem, to the SharmaTassoOlver equation and the (2+1)dimensional modified Boussinesq equation. Our approach provides first integrals in ... 
Application of the expfunction method to nonlinear lattice differential equations for multiwave and rational solutions
(Wiley, 201109)In this paper, we extend the basic Expfunction method to nonlinear lattice differential equations for constructing multiwave and rational solutions for the first time. We consider a differentialdifference analogue of ...

Application of the G′ / Gexpansion method to Kawahara type equations using symbolic computation
(Elsevier, 201006)In this paper, Kawahara type equations are selected to illustrate the effectiveness and simplicity of the G′ / Gexpansion method. With the aid of a symbolic computation system, three types of more general traveling wave ... 
Applications of the pseudo residualfree bubbles to the stabilization of convectiondiffusionreaction problems
(Springer, 201203)It is known that the enrichment of the polynomial finite element space of degree 1 by bubble functions results in a stabilized scheme of the SUPGtype for the convectiondiffusionreaction problems. In particular, the ... 
Applications of the pseudo residualfree bubbles to the stabilization of the convectiondiffusionreaction problems in 2D
(Elsevier, 201408)A stabilized finite element method is studied herein for twodimensional convectiondiffusionreaction problems. The method is based on the residualfree bubbles (RFB) method. However we replace the RFB functions by their ... 
Azimuthal decorrelation of jets widely separated in rapidity in pp collisions at √s = 7 TeV
(Springer, 201608)The decorrelation in the azimuthal angle between the most forward and the most backward jets (MuellerNavelet jets) is measured in data collected in pp collisions with the CMS detector at the LHC at s=7 TeV. The measurement ... 
Bianchi I model: An alternative way to model the presentday Universe
(Oxford University Press, 201408)Although the new era of highprecision cosmology of the cosmic microwave background (CMB) radiation improves our knowledge to understand the infant as well as the presentday Universe, it also leads us to question the main ...
