Homeostasis in Input-Output Networks: Structure, Classification and Applications

no code implementations6 May 2024 Fernando Antoneli, Martin Golubitsky, Jiaxin Jin, Ian Stewart

Mathematically, the notion of homeostasis can be formalized in terms of an input-output function that maps the parameter representing the external disturbance to the output variable that must be kept within a fairly narrow range.

Homeostasis in Gene Regulatory Networks

no code implementations12 Sep 2023 Fernando Antoneli, Martin Golubitsky, Jiaxin Jin, Ian Stewart

In this paper, we use the framework of infinitesimal homeostasis to study general design principles for the occurrence of homeostasis in gene regulatory networks.

Homeostatic Mechanisms in Biological Systems

no code implementations22 Feb 2022 Pedro P. A. Cardoso de Andrade, João L. O. Madeira, Fernando Antoneli

The analysis is based on the notions of infinitesimal homeostasis and near-perfect homeostasis.

Homeostasis in Networks with Multiple Input Nodes and Robustness in Bacterial Chemotaxis

no code implementations5 Nov 2020 João Luiz de Oliveira Madeira, Fernando Antoneli

In this context, we improve a general theory for the analysis of homeostasis in network dynamical systems with distinguished input and output nodes, called `input-output networks'.

The Structure of Infinitesimal Homeostasis in Input-Output Networks

no code implementations8 Jul 2020 Yangyang Wang, Zhengyuan Huang, Fernando Antoneli, Martin Golubitsky

We show that there is an $(n+1)\times(n+1)$ homeostasis matrix $H(\mathcal{I})$ for which $dx_o/d\mathcal{I} = 0$ if and only if $\det(H) = 0$.
