Oscillation criteria for second-order nonlinear delay dynamic equations of neutral type
Advances in Difference Equations, 2018 We investigate oscillatory behavior of solutions to a class of second-order nonlinear neutral delay dynamic equations with nonpositive neutral coefficients. In particular, we study the corresponding noncanonical neutral differential equations.

Second-order resummed thermodynamic perturbation theory for central-force associating potential: Multi-patch colloidal models [PDF]
, 2013 We propose a second-order version of the resummed thermodynamic perturbation theory for patchy colloidal models with arbitrary number of multiply bondable patches.

Axioms, 2021 The aim of this work is to present new oscillation results for a class of second-order delay differential equations with damping term. The new criterion of oscillation depends on improving the asymptotic properties of the positive solutions of the ...

Conceptualizing Leader–Member Exchange as a Second-Order Construct
Frontiers in Psychology, 2022 To date, scholars have focused a considerable amount of effort on developing valid measures of leader–member exchange (LMX). Although useful, it is unclear whether this proliferation in measurement is warranted.

Second-Order Disjoint Factor Analysis [PDF]
Psychometrika, 2022 Hierarchical models are often considered to measure latent concepts defining nested sets of manifest variables. Therefore, by supposing a hierarchical relationship among manifest variables, the general latent concept can be represented by a tree structure where each internal node represents a specific order of abstraction for the latent concept ...

Oscillatory results for second-order noncanonical delay differential equations [PDF]
Opuscula Mathematica, 2019 The main purpose of this paper is to improve recent oscillation results for the second-order half-linear delay differential equation \[\left(r(t)\left(y'(t)\right)^\gamma\right)'+q(t)y^\gamma(\tau(t))= 0, \quad t\geq t_0,\] under the condition \[\int_ ...

The curvature perturbation at second order [PDF]
, 2015 We give an explicit relation, up to second-order terms, between scalar-field fluctuations defined on spatially-flat slices and the curvature perturbation on uniform-density slices.

On second-order characterizability [PDF]
Logic Journal of IGPL, 2012 We investigate the extent of second order characterizable structures by extending Shelah's Main Gap dichotomy to second order logic. For this end we consider a countable complete first order theory T. We show that all sufficiently large models of T have a characterization up to isomorphism in the extension of second order logic obtained by adding a ...

Second Order Noncommutative Corrections to Gravity [PDF]
, 2006 In this work, we calculate the leading order corrections to general relativity formulated on a canonical noncommutative spacetime. These corrections appear in the second order of the expansion in theta.

Monadic second-order definable graph orderings [PDF]
, 2014 We study the question of whether, for a given class of finite graphs, one can define, for each graph of the class, a linear ordering in monadic second-order logic, possibly with the help of monadic parameters.
