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.

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 ...

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.

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_ ...

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 ...

On second-order cone positive systems
, 2021 Internal positivity offers a computationally cheap certificate for external (input-output) positivity of a linear time-invariant system. However, the drawback with this certificate lies in its realization dependency. Firstly, computing such a realization

Maximum Inaccuracies of Second Order [PDF]
Computer Science Journal of Moldova, 2015 Let an indirectly measurable variable $Y$ be represented as a function of finite number of directly measurable variables $X_1, \linebreak X_2, ..., X_n$. We introduce maximum absolute and relative inaccuracies of second order of $Y$ -- this idea is a

Pure Second-Order Logic with Second-Order Identity
Notre Dame Journal of Formal Logic, 2010 Pure second-order logic is second-order logic without functional or first-order variables. In "Pure Second-Order Logic," Denyer shows that pure second-order logic is compact and that its notion of logical truth is decidable. However, his argument does not extend to pure second-order logic with second-order identity.

Second Order Itô Processes [PDF]
Nagoya Mathematical Journal, 1969 A first order stochastic differential equation is any equation which can be expressed symbolically in the form (1. 1)m and σ are called the drift and diffusion coefficients and z( · ) is usually a Brownian motion process.

Oscillation of Second-Order Half-linear Retarded Difference Equations via a Canonical Transform
Nonautonomous Dynamical Systems, 2022 The aim of this paper is to investigate the second order half-linear retarded difference equation Δ(μ(n)(Δη(n))α)+δ(n)ηα(σ(n))=0\Delta \left( {\mu \left( n \right){{\left( {\Delta \eta \left( n \right)} \right)}^\alpha }} \right) + \delta \left( n \right)
