A minimal physical model for curvotaxis driven by curved protein complexes at the cell's leading edge
Raj Kumar Sadhu, Marine Luciano, Wang Xi +12
Cells often migrate on curved surfaces inside the body, such as curved tissues, blood vessels or highly curved protrusions of other cells. Recent \textit{in-vitro} experiments prov…
Wavy membranes and the growth rate of a planar chemical garden: Enhanced diffusion and bioenergetics
Yang Ding, Bruno Batista, Oliver Steinbock +2
In order to model ion transport across protocell membranes in Hadean hydrothermal vents, we consider both theoretically and experimentally the planar growth of a precipitate membra…
Scroll wave drift along steps, troughs and corners
Hua Ke, Zhihui Zhang, Oliver Steinbock
Three-dimensional excitable systems can create nonlinear scroll waves that rotate around one-dimensional phase singularities. Recent theoretical work predicts that these filaments…
Scroll Waves Pinned to Moving Heterogeneities
Hua Ke, Zhihui Zhang, Oliver Steinbock
Three-dimensional excitable systems can selforganize vortex patterns that rotate around one-dimensional phase singularities called filaments. In experiments with the Belousov-Zhabo…
Analysis of Anchor-Size Effects on Pinned Scroll Waves and Measurement of Filament Rigidity
Elias Nakouzi, Zulma A. Jiménez, Vadim N. Biktashev +1
Inert, spherical heterogeneities can pin three-dimensional scroll waves in the excitable Belousov-Zhabotinsky reaction. Three pinning sites cause initially circular rotation backbo…
Spatial Confinement Causes Lifetime Enhancement and Expansion of Vortex Rings with Positive Filament Tension
Jan F. Totz, Harald Engel, Oliver Steinbock
We study the impact of spatial confinement on the dynamics of three-dimensional excitation vortices with circular filaments. In a chemically active medium we observe a decreased co…
