Second-order logic : ontological and epistemological problems [PDF]

open access: yes, 2015
In this thesis I provide a survey over different approaches to second-order logic and its interpretation, and introduce a novel approach. Of special interest are the questions whether (a particular form of) second-order logic can count as logic in some

No local cancellation between directionally opposed first-order and second-order motion signals [PDF]

open access: yes, 2000
Despite strong converging evidence that there are separate mechanisms for the processing of first-order and second-order motion, the issue remains controversial. Qian, Andersen and Adelson (J.

A note on phase-lag computations for multiderivative methods for second order periodic initial value problems [PDF]

open access: yes, 1985
Phase—lag computations are carried out for a family of two-step multiderivative methods for solving second order initial value problems of the form y" = f(t,y), y(t0) = y0, y'(t0) = z0.

Second order Standard Model

open access: yesNuclear Physics B, 2015
It is known, though not commonly, that one can describe fermions using a second order in derivatives Lagrangian instead of the first order Dirac one.

Oscillatory behavior of second-order damped differential equations with a superlinear neutral term [PDF]

open access: yesOpuscula Mathematica, 2020
This article concerns the oscillatory behavior of solutions to second-order damped nonlinear differential equations with a superlinear neutral term. The results are obtained by a Riccati type transformation as well as by an integral criterion.

A multicarrier amplifier design linearized trough second harmonics and second-order IM feedback [PDF]

open access: yes, 2001
A novel linearisation technique for reduction in the first and second kind of the third-order intermodulation products was applied in this paper. The second harmonics and second-order intermodulation products are led from the output to the input of a ...

Second order Zeeman interaction and ferroquadrupolar order in TmVO4

open access: yesnpj Quantum Materials, 2022
TmVO4 exhibits ferroquadrupolar order of the Tm 4f electronic orbitals at low temperatures, and is a model system for Ising nematicity. A magnetic field oriented along the c-axis constitutes a transverse effective field for the quadrupolar order ...

Second order symmetric duality in fractional variational problems over cone constraints [PDF]

open access: yesYugoslav Journal of Operations Research, 2018
In the present paper, we introduce a pair of second order fractional symmetric variational programs over cone constraints and derive weak, strong, and converse duality theorems under second order F-convexity assumptions. Moreover, self duality theorem is
