A1L10 phase boundaries and anisotropy via multipleorderparameter theory for an fcc alloy
Tanoğlu, Gamze; Braun, Richard J.; Cahn, John W.; McFadden, Geoffrey B. (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 ... 
Abelian ChernSimons vortices and holomorphic Burgers hierarchy
Pashaev, Oktay; Gürkan, Zeynep Nilhan (Springer, 200707)We consider the Abelian ChernSimons gauge field theory in 2+1 dimensions and its relation to the holomorphic Burgers hierarchy. We show that the relation between the complex potential and the complex gauge field as in ... 
Absolute cosupplement and absolute cococlosed modules
Keskin Tütüncü, Derya; Toksoy, Sultan Eylem (Hacettepe Üniversitesi, 2013)A module M is called an absolute cococlosed (absolute cosupplement) module if whenever M ≅ T/X the submodule X of T is a coclosed (supplement) submodule of T. Rings for which all modules are absolute cococlosed (absolute ... 
Analysis of a corner layer problem in anisotropic interfaces
Alikakos, N. D.; Bates, P. W.; Cahn, J. W.; Fife, P. C.; Fusco, G.; Tanoğlu, Gamze (Southwest Missouri State University, 200603)We investigate a model of anisotropic diffuse interfaces in ordered FCC crystals introduced recently by Braun et al and Tanoglu et al [3, 18, 19], focusing on parametric conditions which give extreme anisotropy. For a ... 
Analytic study on two nonlinear evolution equations by using the (G′/G)expansion method
Aslan, İsmail; Öziş, Turgut (Elsevier, 200903)The validity and reliability of the socalled (G′/G)expansion method is tested by applying it to two nonlinear evolutionary equations. Solutions in more general forms are obtained. When the parameters are taken as special ... 
An application with webMathematica
Ufuktepe, Ünal (Springer, 2003)There have been many technological dawns in the last 30 years, during which the desktop computer and the Internet have been developed. The importance of Internet in education, particularly using its Web is a wellrecognized ... 
Applications of graph coloring
Ufuktepe, Ünal; Bacak, Gökşen (Springer, 2005)A graph G is a mathematical structure consisting of two sets V(G) (vertices of G) and E(G) (edges of G). Proper coloring of a graph is an assignment of colors either to the vertices of the graphs, or to the edges, in such ... 
Applying Mathematica and webMathematica to graph coloring
Ufuktepe, Ünal; Bacak, Gökşen (Elsevier, 200706)This paper analyzes some graph issues by using the symbolic program Mathematica and its version for the Web, webMathematica. In particular, we consider the problem of graph coloring: the assignment of colors to the ... 
Asymptotic behavior of linear impulsive integrodifferential equations
Akhmet, Marat; Tleubergenova, M. A.; Yılmaz, Oğuz (Elsevier, 200808)Asymptotic equilibria of linear integrodifferential equations and asymptotic relations between solutions of linear homogeneous impulsive differential equations and those of linear integrodifferential equations are ... 
Azimuthal anisotropy of charged particles with transverse momentum up to 100 GeV/c in PbPb collisions at √sNN=5.02 TeV
CMS Collaboration; Karapınar, Güler (Elsevier, 201801)The Fourier coefficients v2 and v3 characterizing the anisotropy of the azimuthal distribution of charged particles produced in PbPb collisions at sNN=5.02 TeV are measured with data collected by the CMS experiment. The ... 
Basic calculus on time scale with mathematica
Yantır, Ahmet; Ufuktepe, Ünal (Springer, 2003)Mathematical modeling of time dependent systems are always interesting for applied mathematicians. First continuous and then discrete mathematical modeling are built during the mathematical development from ancient to the ... 
Berry's phase under the DzyaloshinskiiMoriya interaction
Kwan, M. K.; Gürkan, Zeynep Nilhan; Kwek, L. C. (American Physical Society, 200806)In this paper, we study the DzyaloshinskiiMoriya (DM) anisotropic XX spinchain model in the presence of an external homogeneous magnetic field. We found that the Berry phase of the system varies interestingly with small ... 
Black holes and solitons of the quantized dispersionless NLS and DNLS equations
Pashaev, Oktay; Lee, Jyh Hao (Cambridge University Press, 200207)The classical dynamics of nonrelativistic particles are described by the Schrödinger wave equation, perturbed by quantum potential nonlinearity. Quantization of this dispersionless equation, implemented by deformation of ... 
Boosting the decay of solutions of the linearised Kortewegde Vries–Burgers equation to a predetermined rate from the boundary
Özsarı, Türker; Arabacı, Eda (Taylor & Francis, 2019)The aim of this article is to extend recent results on the boundary feedback controllability of the Kortewegde Vries equation to the Kortewegde Vries–Burgers equation which is posed on a bounded domain. In the first part ... 
A boundary integral equation for the transmission eigenvalue problem for Maxwell equation
Cakoni, Fioralba; Ivanyshyn Yaman, Olha; Kress, Rainer; Le Louër, Frédérique (Wiley, 201803)We propose a new integral equation formulation to characterize and compute transmission eigenvalues in electromagnetic scattering. As opposed to the approach that was recently developed by Cakoni, Haddar and Meng (2015) ... 
Boundary shape and Casimir energy
Ahmedov, Hacı; Duru, İsmail Hakkı (IOP Publishing, 200908)Casimir energy changes are investigated for geometries obtained by small but arbitrary deformations of a given geometry for which the vacuum energy is already known for the massless scalar field. As a specific case, ... 
CAMPways: Constrained alignment framework for the comparative analysis of a pair of metabolic pathways
Abaka, Gamze; Bıyıkoğlu, Türker; Erten, Cesim (Oxford University Press, 201307)Motivation: Given a pair of metabolic pathways, an alignment of the pathways corresponds to a mapping between similar substructures of the pair. Successful alignments may provide useful applications in phylogenetic tree ...
