Loop Corrections in Non-Linear Cosmological Perturbation Theory [PDF]

open access: yes, 1995
Using a diagrammatic approach to Eulerian perturbation theory, we analytically calculate the variance and skewness of the density and velocity divergence induced by gravitational evolution from Gaussian initial conditions, including corrections *beyond ...

Estimations for the convex modular of the aliasing error of nonlinear sampling Kantorovich operators

open access: yesNonlinear Analysis
In this paper, we establish quantitative estimates for the nonlinear sampling Kantorovich operators in the general setting of modular spaces Lρ. To achieve this, we consider a notion of modulus of smoothness based on the convex modular functional ρ ...

A Complete Version of the Glauber Theory for Elementary Atom - Target Atom Scattering and Its Approximations

open access: yes, 2014
A general formalism of the Glauber theory for elementary atom (EA) - target atom (TA) scattering is developed. A second-order approximation of its complete version is considered in the framework of the optical-model perturbative approach.

A robust high-order Lagrange-projection like scheme with large time steps for the isentropic Euler equations [PDF]

open access: yes, 2016
We present an extension to high-order of a first-order Lagrange-projection like method for the approximation of the Euler equations introduced in Coquel {\it et al.} (Math. Comput., 79 (2010), pp.~1493--1533).

Approximation of Second-Order Moment Processes from Local Averages

open access: yesJournal of Inequalities and Applications, 2009
We use local averages to approximate processes that have finite second-order moments and are continuous in quadratic mean. We also provide some insight and generalization of the connection between Bernstein polynomials and Brownian motion, which was ...

The approximation of Laplace-Stieltjes transforms with finite order

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we study the irregular growth of an entire function defined by the Laplace-Stieltjes transform of finite order convergent in the whole complex plane and obtain some results about λ-lower type.

Lowest order Virtual Element approximation of magnetostatic problems

open access: yes, 2017
We give here a simplified presentation of the lowest order Serendipity Virtual Element method, and show its use for the numerical solution of linear magneto-static problems in three dimensions.

Exact Conservation Laws of the Gradient Expanded Kadanoff-Baym Equations [PDF]

open access: yes, 2001
It is shown that the Kadanoff-Baym equations at consistent first-order gradient approximation reveal exact rather than approximate conservation laws related to global symmetries of the system.

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Path Integral Ground State with a Fourth-Order Propagator: Application to Condensed Helium

open access: yes, 2005
Ground state properties of condensed Helium are calculated using the Path Integral Ground State (PIGS) method. A fourth-order approximation is used as short (imaginary) time propagator.
