    We show the abundance of Exceptional Points in the generic asymmetric configuration of two coupled diode lasers, under nonzero optical detuning and differential pumping. We pinpoint the location of these points with ...
  • Exceptional sets in homogeneous spaces and hausdorff dimension 
    Kadyrov, Shirali (2015)
    In this paper we study the dimension of a family of sets arising in open dynamics. We use exponential mixing results for diagonalizable ows in compact homogeneous spaces X to show that the Hausdorff dimension of set of ...
  • Excited States of Positronic Lithium and Beryllium 
    Bubin, Sergiy; Prezhdo, Oleg V. (2013)
    Using a variational method with an explicitly correlated Gaussian basis, we study the eþ-Li and eþ-Be complexes in the ground and lowest excited states with higher spin multiplicity. Our calculations provide rigorous ...
  • Existence of Equilibrium States of Hollow Hollomon Cylinders Submerged in a Fluid 
    Elgindi, Mohamed B. M.; Wei, Dongming (Applied Mathematical Sciences, 2013)
    This paper is concerned with the existence of equilibrium states of a thin-walled hollow elasto-plastic cylinders fully or partially submerged in a fluid. This problem serves as a model for many problems with engineering ...
  • Existence, Uniqueness, and Numerical Analysis of Solutions of a Quasilinear ParabolicProblem 
    Wei, Dongming (Society for Industrial and Applied Mathematics. SIAM Journal on Numerical Analysis, 1992-04)
    A quasilinear parabolic problem is studied. By using the method of lines, the existence and uniqueness of a solution to the initial boundary value problem with sufficiently smooth initial conditions are shown. Also given ...
  • Exogenous cathepsin G upregulates cell surface MHC class I molecules on immune and glioblastoma cells

    Major histocompatibility complex (MHC) class I molecules present antigenic peptides to cytotoxic T cells. During an adaptive immune response, MHC molecules are regulated by several mechanisms including lipopolysaccharide ...
  • Experimental and theoretical analysis of organic dyes having a double D-π-A configurations for dye-sensitized solar cells 
    Balanay, Mannix P.; Choi, Kyu Seok; Lee, Sang Hee; Kim, Dong Hee (Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2017-02-15)
    Two spiro-like organic dyes linked at the thiophene bridge (KS-11 and KS-12) together with the original rod-shaped D-π-A configuration (C1) were designed, synthesized, and characterized based on their electronic structure, ...
  • Experimental study of Pac-Man conditions for learn-ability of discrete linear dynamical systems 
    Damiyev, Zhaksybek (Nazarbayev University School of Science and Technology, 2019-05-01)
    In this work, we are going to reconstruct parameters of a discrete dynamical system with a hidden layer, given by a quadruple of matrices (𝐴,𝐵,𝐶,𝐷), from system’s past behaviour. First, we reproduced experimentally ...
