Correction of non-linearity effects in detectors for electron spectroscopy

open access: yes, 2004
Using photoemission intensities and a detection system employed by many groups in the electron spectroscopy community as an example, we have quantitatively characterized and corrected detector non-linearity effects over the full dynamic range of the ...

Spectral Effects of Strong Chi-2 Non-Linearity for Quantum Processing

open access: yes, 2008
Optical $\chi^{(2)}$ non-linearity can be used for parametric amplification and producing down-converted entangled photon pairs that have broad applications. It is known that weak non-linear media exhibit dispersion and produce a frequency response.

Reaction-diffusion systems with 1-homogeneous non-linearity

open access: yesElectronic Journal of Differential Equations, 2002
We describe the dynamics of a system of two reaction-diffusion equations with 1-homogeneous non-linearity. We show that either an order-preserving property holds and can be used in order to determine the limiting behaviour in some (invariant) sets or the

First ten years of active metamaterial structures with “negative” elements

open access: yesEPJ Applied Metamaterials, 2018
Almost ten years have passed since the first experimental attempts of enhancing functionality of radiofrequency metamaterials by embedding active circuits that mimic behavior of hypothetical negative capacitors, negative inductors and negative resistors.

Non-Linear Predictive Control

open access: yesIFAC Proceedings Volumes, 1991
Abstract In this contribution, an approach to nonlinear predictive control is discussed. The philosophy involves the use of an on-line optimisation algorithm to determine the future inputs that will minimise the deviations between desired and predicted outputs. Control, however, is implemented in a receding horizon fashion.

Long memory and non-linearity in Stock Markets [PDF]

open access: yes
In this paper the long memory and non-linear properties of share prices in the UK’s Stock Exchange and AIM are explored. The results suggest that the most commonly traded shares exhibit long memory thus raising interesting issues about the validity of ...

The non-linearity between populist attitudes and ideological extremism

open access: yesPolitical Science Research and Methods
The relationship between populist attitudes and ideological orientations remains an area of considerable academic interest, yet much is still unknown about the ideological inclinations associated with populist attitudes.
