Alternative stable states, nonlinear behavior, and predictability of microbiome dynamics

open access: yesMicrobiome, 2023
Background Microbiome dynamics are both crucial indicators and potential drivers of human health, agricultural output, and industrial bio-applications. However, predicting microbiome dynamics is notoriously difficult because communities often show abrupt

Nonlinear alternating current responses of graded materials [PDF]

open access: yesPhysical Review E, 2004
When a composite of nonlinear particles suspended in a host medium is subjected to a sinusoidal electric field, the electrical response in the composite will generally consist of alternating current (AC) fields at frequencies of higher-order harmonics.

Mild solutions for perturbed evolution equations with infinite state-dependent delay

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
In this paper, we give sufficient conditions to get the existence of mild solutions for two classes of first order partial and neutral of perturbed evolution equations by using the nonlinear alternative of Avramescu for contractions operators in Fréchet ...

A Nonlinear Alternating Direction Method [PDF]

open access: yesMathematics of Computation, 1969
An alternating direction iteration method is formulated, and convergence is proved, for the solution of certain systems of nonlinear equations. The method is applied to a heat conduction problem with a nonlinear boundary condition.

Nonlinear alternating current responses of dipolar fluids [PDF]

open access: yesPhysical Review E, 2004
The frequency-dependent nonlinear dielectric increment of dipolar fluids in nonpolar fluids is often measured by using a stationary relaxation method in which two electric fields are used: The static direct current (DC) field of high strength causing the dielectric nonlinearity, and the probing alternating current (AC) field of low strength and high ...

Linear parameter estimation for multi-degree-of-freedom nonlinear systems using nonlinear output frequency-response functions [PDF]

open access: yes, 2006
The Volterra series approach has been widely used for the analysis of nonlinear systems. Based on the Volterra series, a novel concept named Nonlinear Output Frequency Response Functions (NOFRFs) was proposed by the authors.

Anti-periodic boundary value problems for Caputo-Fabrizio fractional impulsive differential equations [PDF]

open access: yesMathematica Moravica, 2022
In this paper, we shall discuss the existence and uniqueness of solutions for a nonlinear anti-periodic boundary value problem for fractional impulsive differential equations involving a Caputo-Fabrizio fractional derivative of order r ∈ (0, 1).
