(AMER INST PHYSICS, CIRCULATION & FULFILLMENT DIV, 2011-04-01)We have used Monte Carlo simulations to investigate the magnetic properties of asymmetric dots as a function of their geometry. The asymmetry of round dots is produced by cutting off a fraction of the dot and is characterized ...
-
(Elsevier B.V., 2019)The present study evaluates the vibrational energy propagation from an O[dbnd]C stretching through the double or single bonds of two small carboxamide molecules. The results show that double bonding facilitates vibrational ...
-
(Springer, 2017)An analysis of neutron and proton scattering off 40,48Ca has been carried out. Real and imaginary potentials have been generated using the Nuclear Structure Method (NSM) for scattering with the Gogny D1S nucleon-nucleon ...

(1998-06)An asymptotic study of two spectral models which appear in uid{solid vibrations is presented in this paper. These two models are derived under the assumption that the uid is slightly compressible or viscous, respectively. ...

(2000)We study the asymptotic behaviour of the transition density of a Brownian motion in D, killed at @D, where Dc is a compact non polar set. Our main result concern dimension d D 2, where we show that the transition density ...
-
(2000)We prove that the exact non local equation derived by the present authors for the temporal linear evolution of the surface of a viscous incompressible fluid reduces asymptotically for high viscosity to a second order ...
-
(American Mathematical Society, 2020)Consider the Hamiltonian abed system in one dimension, with data posed in the energy space H-1 x H-1. This model, introduced by Bona, Chen, and Saut, is a well-known physical generalization of the classical Boussinesq ...
-
(2007)We provide a sharp generalization to the nonautonomous case of the well-known Kobayashi estimate for proximal iterates associated with maximal monotone operators. We then derive a bound for the distance between ...

(Springer New York LLC, 2019)© 2018, Springer Science+Business Media, LLC, part of Springer Nature.The purpose of this work is to study discrete approximations of evolution equations governed by cocoercive operators by means of Euler iterations, both ...
-
(Elsevier, 2020)In traditional works on numerical schemes for solving stochastic differential equations (SDEs), the globally Lipschitz assumption is often assumed to ensure different types of convergence. In practice, this is often too ...

Asymptotic normality for the counting process of weak records and delta-records in discrete models (2007)Let {X-n, n >= 1} be a sequence of independent and identically distributed random variables, taking non-negative integer values, and call X-n a delta-record if X-n > max{X-1,..., Xn-1} + delta, where delta is an integer ...
-
(CAMBRIDGE UNIV PRESS, 2006-08)Let M = N-D be the positive orthant of a D-dimensional lattice and let (G, +) be a finite abelian group. Let G subset of G(M) be a subgroup shift, and let mu be a Markov random field whose support is G. Let Phi : G -> G ...
-
(SPRINGER, 2008-06)We consider the asymptotic behavior of the solution of one dimensional stochastic differential equations and Langevin equations in periodic backgrounds with zero average. We prove that in several such models, there is ...
-
(NATURE PUBLISHING GROUP, 2003-08-07)Stars that explode as supernovae come in two main classes. A type Ia supernova is recognized by the absence of hydrogen and the presence of elements such as silicon and sulphur in its spectrum; this class of supernova is ...
-
(Association for Computing Machinery, 2017)Given an array A[1, n] of elements with a total order, we consider the problem of building a data structure that solves two queries: (a) selection queries receive a range [i, j] and an integer k and return the position of ...

(PERGAMON-ELSEVIER SCIENCE LTD, 2008-09-01)Let 1 < p < N, and u be a nonnegative solution of -Delta(p)u = f (x, u) on R-N\(B-1) over bar where f behaves like \x\(-l)u(q) near \x\ = infinity and u = 0, for some constants q >= 0 and l is an element of R. We obtain ...

Asymptotics for eigenvalues of the Laplacian in higher dimensional periodically perforated domains (2010)This paper considers the periodic spectral problem associated with the Laplace operator written in RN (N = 3, 4, 5) periodically perforated by balls, and with homogeneous Dirichlet condition on the boundary of holes. We ...
-
(Elsevier, 2016)A multicone domain Omega subset of R-n is an open, connected set that resembles a finite collection of cones far away from the origin. We study the rate of decay in time of the heat kernel p(t, x, y) of a Brownian motion ...

(Springer, 2019)Sorbitol is synthesized in Rosaceae species, especially in source organs, in a pathway involving aldose 6-phosphate reductase (A6PR, EC 1.1.1.200). As compatible solutes, sorbitol and other sugar alcohols assist in the ...
