(European Physical Journal C: Particles and Fields, 2017-07-11)We study the observational properties of a class of exact solutions of Einstein’s field equations describing stationary, axially symmetric, rigidly rotating dust (i.e. noninteracting particles).We ask the questionwhether ...
-
(Nazarbayev University School of Science and Technology, 2016)In this paper we study a stochastic two-particle system on Z where particles interact each other by pushing dynamics. We derive the explicit formulas of the transition probability and of the probability distributions of ...
-
(2006)Let V be a variety of algebras. We establish a condition (so called generalized entropic property), equivalent to the fact that for every algebra A 2 V, the set of all subalgebras of A is a subuniverse of the complex ...
-
(SIAM Journal on Matrix Analysis and Applications, 2014)In this paper we discuss the deflation criterion used in the extended QR algorithm based on the chasing of rotations. We provide absolute and relative perturbation bounds for this deflation criterion. Further, we present ...

One-electron oxidation of chloroquine, cymanquine, and related aminoquinolines in nonaqueous media (Journal of Electroanalytical Chemistry, 2017-08-15)Abstract The anodic oxidation of a series of secondary-amine-substituted chloroquinoline derivatives, 1–5, has been studied in dichloromethane/0.05M [NBu4][B(C6F5)4]. Compounds 4 and 5 contain organometallic moieties of ...
-
(ArXiv, 2017-03-03)A new solution of a unitary moving mirror is found to produce nite energy and emit thermal radiation despite the absence of an acceleration horizon. In the limit that the mirror approaches the speed of light, the model ...
-
(2013)We show that every optimum basis of a nite closure system, in D. Maier's sense, is also right-side optimum, which is a parameter of a minimum CNF representation of a Horn Boolean function. New parameters for the size ...
-
(Statistics & Probability Letters, 2014-01-01)Abstract The K-means algorithm is commonly used with the Euclidean metric. While the use of Mahalanobis distances seems to be a straightforward extension of the algorithm, the initial estimation of covariance matrices can ...
-
(Nazarbayev University School of Science and Technology, 2016-04)Existing distributions do not always provide an adequate fit to the complex real world data. Hence, the interest in developing more flexible statistical distributions remains strong in statistics profession. In this project, ...
-
(2015)A convex geometry is a closure space satisfying the anti-exchange axiom. For several types of algebraic convex geometries we describe when the collection of closed sets is order scattered, in terms of obstructions to the ...
-
(IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS), 2017-11-13)Abstract—Conventional wireless power transfer systems consist of a microwave power generator located at one place and a microwave power receiver located at a distance. To realize efficient power transfer, the system ...
-
(2013-02-01)A single real scalar field of spin zero obeying the Klein-Gordon equation in flat spacetime under external conditions is considered in the context of the spin-statistics connection. An imposed accelerated boundary on the ...
-
(World Journal of Engineering and Technology, 2014)In this paper, we consider the buckling of an Euler-Bernoulli graphene beam due to an axial compressive load. We formulate the problem as a non-linear (eigenvalue) two-point boundary value problem, prove some properties ...
-
(Mathematics Faculty Publications, 2012)In this paper we prove the global solvability of a class of fourth-order nonlinear boundary value problems that govern the deformation of a Hollomon’s power-law plastic beam subject to an axial compression and nonlinear ...
-
(Computing (Vienna/New York), 2010-06-09)The hierarchical ( backslashfancyscriptH -) matrix format allows storing a variety of dense matrices from certain applications in a special data-sparse way with linear-polylogarithmic complexity. Many operations from linear ...
-
(arXiv.org, 2014)In this paper we formulate the equilibrium equation for a beam made of graphene sub- jected to some boundary conditions and acted upon by axial compression and nonlinear lateral constrains as a fourth-order nonlinear ...
-
(arXiv.org, 2016)The nonlinear Brinkman-Forchheimer-extended Darcy equation is used to model some porous medium ow in chemical reactors of packed bed type. The results concerning the existence and uniqueness of a weak solution are ...
-
(Signal Processing, 2017-05-01)Abstract The concept of a mapping, which takes its values in an infinite-dimensional functional space, has been studied by the mathematical community since the third decade of the last century. This effort has produced a ...
-
(Nazarbayev University School of Science and Technology, 2016-05)We study the one-dimensional non-linear non-stationary Boltzmann's moment system of equations in fourth approxi- mation with the tools developed by Sakabekov in [4],[5] and [6]. For the third approximation system Sakabekov ...
-
(IEEE Journal of Selected Topics in Quantum Electronics, 2015)How one can fabricate the Parity-Time (PT) symmetric siblings of commonly used metals in the visible? This work tries to give an answer to that question by providing the features of the active media which conjugately ...
