A simple model for conserved intracellular dynamics exhibits multiscale pattern formation, traveling protein domains and arrested coarsening of lipid domains
Benjamin Winkler, Sergio Alonso, Markus Bär
We model the spatiotemporal dynamics of cellular protein concentrations relevant to cell polarity near membranes composed of different lipids. Therefore, we consider a three-variab…
Black and Gray Box Learning of Amplitude Equations: Application to Phase Field Systems
Felix P. Kemeth, Sergio Alonso, Blas Echebarria +3
We present a data-driven approach to learning surrogate models for amplitude equations, and illustrate its application to interfacial dynamics of phase field systems. In particular…
From single to collective motion of social amoebae: a computational study of interacting cells
Eduardo Moreno, Robert Großmann, Carsten Beta +1
The coupling of the internal mechanisms of cell polarization to cell shape deformations and subsequent cell crawling poses many interdisciplinary scientific challenges. Several mat…
Mass-conservation increases robustness in stochastic reaction-diffusion models of cell crawling
Eduardo Moreno, Sergio Alonso
The process of polarization determines the head and tail of single cells. A mechanism of this kind frequently precedes the subsequent cell locomotion and it determines the directio…
Modeling cell crawling strategies with a bistable model: From amoeboid to fan-shaped cell motion
E. Moreno, S. Flemming, F. Font +3
Eukaryotic cell motility involves a complex network of interactions between biochemical components and mechanical processes. The cell employs this network to polarize and induce sh…
Diffusivity Estimation for Activator-Inhibitor Models: Theory and Application to Intracellular Dynamics of the Actin Cytoskeleton
Gregor Pasemann, Sven Flemming, Sergio Alonso +2
A theory for diffusivity estimation for spatially extended activator-inhibitor dynamics modelling the evolution of intracellular signaling networks is developed in the mathematical…
Spatio-temporal dynamics induced by competing instabilities in two asymmetrically coupled nonlinear evolution equations
David Schueler, Sergio Alonso, Alessandro Torcini +1
Pattern formation often occurs in spatially extended physical, biological and chemical systems due to an instability of the homogeneous steady state. The type of the instability us…
Dynamics of reaction-diffusion patterns controlled by asymmetric nonlocal coupling as limiting case of differential advection
Julien Siebert, Sergio Alonso, Markus Bär +1
A one-component bistable reaction-diffusion system with asymmetric nonlocal coup ling is derived as limiting case of a two-component activator-inhibitor reaction -diffusion model w…
Effects of external global noise on the catalytic CO oxidation on Pt(110)
P. S. Bodega, S. Alonso, H. H. Rotermund
Oxidation reaction of CO on a single platinum crystal is a reaction-diffusion system that may exhibit bistable, excitable, and oscillatory behavior. We studied the effect of a stoc…
Towards active microfluidics: Interface turbulence in thin liquid films with floating molecular machines
Sergio Alonso, Alexander S. Mikhailov
Thin liquid films with floating active protein machines are considered. Cyclic mechanical motions within the machines, representing microscopic swimmers, lead to molecular propulsi…
