Steric interactions and out-of-equilibrium processes control the internal organization of bacteria

no code implementations19 Apr 2021 Ander Movilla Miangolarra, Sophia Hsin-Jung Li, Jean-François Joanny, Ned S. Wingreen, Michele Castellana

Here, we develop a model that takes into account steric interactions among the components of the Escherichia coli transcriptional-translational machinery (TTM) and out-of-equilibrium effects of mRNA transcription, translation, and degradation, in order to explain many observed features of the nucleoid.

Long-time diffusion and energy transfer in polydisperse mixtures of particles with different temperatures

no code implementations11 Mar 2021 Efe Ilker, Michele Castellana, Jean-François Joanny

Evidence suggests that the transport rate of a passive particle at long timescales is enhanced due to interactions with the surrounding active ones in a size- and composition-dependent manner.

A statistical-inference approach to reconstruct inter-cellular interactions in cell-migration experiments

no code implementations4 Dec 2019 Elena Agliari, Pablo J. Sáez, Adriano Barra, Matthieu Piel, Pablo Vargas, Michele Castellana

In the first experiment, cell migrate in a wound-healing model: when applied to this experiment, the inference method predicts the existence of cell-cell interactions, correctly mirroring the strong intercellular contacts which are present in the experiment.
