Time-evolution of squeezed coherent states of a generalized quantum parametric oscillator
(American Institute of Physics, 2019-06)Time evolution of squeezed coherent states for a quantum parametric oscillator with the most general self-adjoint quadratic Hamiltonian is found explicitly. For this, we use the unitary displacement and squeeze operators ... -
Towards denial-of-service-resilient key agreement protocols
(Springer, 2009)Denial of service resilience is an important practical consideration for key agreement protocols in any hostile environment such as the Internet. There are well-known models that consider the security of key agreement ... -
Transverse momentum spectra of inclusive b jets in pPb collisions at √sNN=5.02 TeV
(Elsevier, 2016-03)We present a measurement of b jet transverse momentum (pT) spectra in proton-lead (pPb) collisions using a dataset corresponding to about 35 nb-1 collected with the CMS detector at the LHC. Jets from b quark fragmentation ... -
Traveling wave solutions for nonlinear differential-difference equations of rational types
(Institute of Physics Publishing, 2016-01-01)Differential-difference equations are considered to be hybrid systems because the spatial variable n is discrete while the time t is usually kept continuous. Although a considerable amount of research has been carried out ... -
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 ... -
Travelling wave solutions to nonlinear physical models by means of the first integral method
(Indian Academy of Sciences, 2011-04)This paper presents the first integral method to carry out the integration of nonlinear partial differential equations in terms of travelling wave solutions. For illustration, three important equations of mathematical ... -
Two-circles theorem, q-periodic functions and entangled qubit states
(IOP Publishing, 2014)For arbitrary hydrodynamic flow in circular annulus we introduce the two circle theorem, allowing us to construct the flow from a given one in infinite plane. Our construction is based on q-periodic analytic functions for ... -
Two-level finite element method with a stabilizing subgrid for the incompressible MHD equations
(Wiley, 2010-01)We consider the Galerkin finite element method (FEM) for the incompressible magnetohydrodynamic (MHD) equations in two dimension. The domain is discretized into a set of regular triangular elements and the finite-dimensional ... -
Two-level finite element method with a stabilizing subgrid for the incompressible Navier-Stokes equations
(Wiley, 2008-10-20)We consider the Galerkin finite element method for the incompressible Navier-Stokes equations in two dimensions. The domain is discretized into a set of regular triangular elements and the finite-dimensional spaces employed ... -
Utilizing postponed ephemeral and pseudo-static keys in tripartite and identity-based key agreement protocols
(International Association for Cryptologic Research, 2009)We propose an new one-round implicitly authenticated three-party protocol that extends Joux's protocol as well as a two-party identity-based protocol. Our protocols have a single communication round that consists of ephemeral ... -
Variations on a theme of q-oscillator
(IOP Publishing, 2015-07-01)We present several ideas in the direction of physical interpretation of q- and f-oscillators as nonlinear oscillators. First we show that an arbitrary one-dimensional integrable system in action-angle variables can be ... -
Vector shock soliton and the Hirota bilinear method
(Elsevier, 2005-10)The Hirota bilinear method is applied to find an exact shock soliton solution of the system reaction-diffusion equations for n-component vector order parameter, with the reaction part in form of the third order polynomial, ... -
Vertex-decomposable graphs, codismantlability, cohen-macaulayness, and castelnuovo-mumford regularity
(Electronic Journal of Combinatorics, 2014-01)We call a vertex x of a graph G = (V, E) a codominated vertex if NG[y] ⊆ NG[x] for some vertex y ∈ V \{x}, and a graph G is called codismantlable if either it is an edgeless graph or it contains a codominated vertex x such ... -
Vortex images and q-elementary functions
(IOP Publishing, 2008-04)In the present paper, the problem of vortex images in the annular domain between two coaxial cylinders is solved by the q-elementary functions. We show that all images are determined completely as poles of the q-logarithmic ... -
Vortex images, q-calculus and entangled coherent states
(IOP Publishing, 2012)The two circles theorem for hydrodynamic flow in annular domain bounded by two concentric circles is derived. Complex potential and velocity of the flow are represented as q-periodic functions and rewritten in terms of the ... -
Weakly distributive modules. Applications to supplement submodules
(Indian Academy of Sciences, 2010-11)In this paper, we define and study weakly distributive modules as a proper generalization of distributive modules. We prove that, weakly distributive supplemented modules are amply supplemented. In a weakly distributive ... -
Weighted bloch, lipschitz, zygmund, bers, and growth spaces of the ball: Bergman projections and characterizations
(Elsevier, 2011-02)We determine precise conditions for the boundedness of Bergman projections from Lebesgue classes onto the spaces in the title, which are members of the same one-parameter family of spaces. The projections provide integral ... -
Well posedness conditions for Bimodal Piecewise Affine Systems
(Elsevier, 2015-07-01)This paper considers well-posedness (the existence and uniqueness of the solutions) of Bimodal Piecewise Affine Systems in ℝn. It is assumed that both modes are observable, but only one of the modes is in observable canonical ... -
Well posedness conditions for planar conewise linear systems
(Sage Publications, 2019-05)In this study, we give well-posedness conditions for planar conewise linear systems where the vector field is not necessarily continuous. It is further shown that, for a certain class of planar conewise linear systems, ... -
Well-posedness for nonlinear Schrödinger equations with boundary forces in low dimensions by Strichartz estimates
(Elsevier, 2015-04)In this paper, we study the well-posedness of solutions for nonlinear Schrödinger equations on one and two dimensional domains with boundary where the boundary is disturbed by an external inhomogeneous type of Dirichlet ...
