Neighborhood Approximations for Non-Linear Voter Models [PDF]

open access: yesEntropy, 2015
Non-linear voter models assume that the opinion of an agent depends on the opinions of its neighbors in a non-linear manner. This allows for voting rules different from majority voting. While the linear voter model is known to reach consensus, non-linear

Non-linear and non-symmetric exchange-rate adjustment: new evidence from medium and high inflation countries [PDF]

open access: yes, 2003
This paper analyses a model of non-linear exchange rate adjustment that extends the literature by allowing asymmetric responses to over- and under-valuations.

Distributed lag non-linear models. [PDF]

open access: yesStat Med, 2010
Abstract Environmental stressors often show effects that are delayed in time, requiring the use of statistical models that are flexible enough to describe the additional time dimension of the exposure–response relationship.

Reducing and meta-analysing estimates from distributed lag non-linear models. [PDF]

open access: yesBMC Med Res Methodol, 2013
BACKGROUND: The two-stage time series design represents a powerful analytical tool in environmental epidemiology. Recently, models for both stages have been extended with the development of distributed lag non-linear models (DLNMs), a methodology for ...

Automatic Selection for Non-linear Models [PDF]

open access: yes, 2012
Our strategy for automatic selection in potentially non-linear processes is: test for non-linearity in the unrestricted linear formulation; if that test rejects, specify a general model using polynomials, to be simplified to a minimal congruent representation; finally select by encompassing tests of specific non-linear forms against the selected model.

Non-linear Hamiltonian models for DNA

open access: yesEuropean Biophysics Journal, 2022
Nucleic acids' physical properties have been investigated by theoretical methods based both on fully atomistic representations and on coarse-grained models, e.g., the worm-like-chain, taken from polymer physics. In this review article, I discuss an intermediate (mesoscopic) approach and show how to build a three-dimensional Hamiltonian model which ...

Production Constraints Modelling: A Tactical Review Approach [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2020
A constraint is a limitation or a restriction that poses a threat to the performance and efficiency of a system. This paper presented a tactical review approach to production constraints modeling.

Linear and non-linear optimization models for the selection of investment portfolio

open access: yesLietuvos Matematikos Rinkinys, 2021
This research suggests a maxmin model for the selection of investment portfolios. The risk evaluation coefficients are introduced. The components of portfolio are found by solving linear programming task in onemodel and non-linear programming task in the

Non-linear modelling of breast tissue

open access: yesMathematical Medicine and Biology, 2007
Previous approaches to modelling the large deformation of breast tissue, as occurs, e.g. in imaging using magnetic resonance imaging or mammography, include using linear elasticity and pseudo-non-linear elasticity, in which case the non-linear deformation is approximated by a series of small linear isotropic deformations, with the (constant) Young's ...
