Some results on second order controllability conditions

, 2019
For a symmetric system, we want to study the problem of crossing an hypersurface in the neighborhood of a given point, when we suppose that all of the available vector fields are tangent to the hypersurface at the point.

Forced oscillation of second-order superlinear dynamic equations on time scales

Electronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, by constructing a class of Philos type functions on time scales, we investigate the oscillation of the following second-order forced nonlinear dynamic equation $$x^{\Delta\Delta}(t)-p(t)|x(q(t))|^{\lambda-1}x(q(t))=e(t),\quad t\in\mathbb{T}

A framework for second-order parton showers

, 2017
A framework is presented for including second-order perturbative corrections to the radiation patterns of parton showers. The formalism allows to combine O(alphaS^2)-corrected iterated 2->3 kernels for "ordered" gluon emissions with tree-level 2->4 ...

Second order perturbation theory for embedded eigenvalues

, 2010
We study second order perturbation theory for embedded eigenvalues of an abstract class of self-adjoint operators. Using an extension of the Mourre theory, under assumptions on the regularity of bound states with respect to a conjugate operator, we prove

Second Order General Slow-Roll Power Spectrum

, 2004
Recent combined results from the Wilkinson Microwave Anisotropy Probe (WMAP) and Sloan Digital Sky Survey (SDSS) provide a remarkable set of data which requires more accurate and general investigation.

Visual motion sensitivity as an indicator of diabetic retinopathy in type 2 diabetes mellitus

Frontiers in Neuroscience
ObjectivesThis current study is based on a set of visual motion sensitivity tests, investigating the correlation between visual motion sensitivity and diabetic retinopathy (DR) in type 2 diabetes mellitus (T2DM), thereby furnishing a scientific rationale

Second order formalism in Poincare gauge theory

, 2006
Changing the set of independent variables of Poincare gauge theory and considering, in a manner similar to the second order formalism of general relativity, the Riemannian part of the Lorentz connection as function of the tetrad field, we construct ...

MAC Resolvability: First And Second Order Results

, 2017
Building upon previous work on the relation between secrecy and channel resolvability, we revisit a secrecy proof for the multiple-access channel from the perspective of resolvability.

Asymptotic behavior of second-order impulsive differential equations

Electronic Journal of Differential Equations, 2011
In this article, we study the asymptotic behavior of all solutions of 2-th order nonlinear delay differential equation with impulses. Our main tools are impulsive differential inequalities and the Riccati transformation.
