Special Issue Information

Dear Colleagues,

Recently, there has been impressive experimental and theoretical progress concerning the dynamical properties of noise-driven systems that are far from equilibrium. For example, researchers are now able to directly measure stationary, nonzero probability current densities in biophysical systems such as beating flagella and migrating cells. Such measurements can provide direct evidence of detailed balance violation, an essential feature in the functioning of many non-equilibrium systems. At the same time, there is substantial theoretical effort to understand fluctuation properties in such systems by proposing new quantitative approaches to characterize the breaking of detailed balance. Similar phenomena are also observed across a diverse set of fields including climate modeling, nanoscale mechanical systems, active matter, colloidal particles, and electronic circuits. The proposed Special Issue of Entropy is targeted at experimental and theoretical physicists and applied mathematicians from a range of traditional fields spanning biophysics, nonlinear and statistical physics, condensed and soft matter physics, as well as climate physics for whom it will be stimulating to explore common sets of new and emerging experimental techniques and theoretical tools and approaches for understanding the noisy dynamics of far-from-equilibrium systems.

This Special Topic has been the subject of contributed and invited sessions at two recent high profile scientific meetings including the 2019 APS March Meeting in Boston and the 2019 SIAM Dynamical Systems meeting in Snowbird, Utah. Both sets of sessions generated significant interest measured by attendance and discussions. The APS session generated approximately 40 contributed talks spread over three individual segments. This information provides additional support for the timeliness of the proposed topic of this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Incorporating Cellular Stochasticity in Solid–Fluid Mixture Biofilm Models

Abstract
The dynamics of cellular aggregates is driven by the interplay of mechanochemical processes and cellular activity. Although deterministic models may capture mechanical features, local chemical fluctuations trigger random cell responses, which determine the overall evolution.

The dynamics of cellular aggregates is driven by the interplay of mechanochemical processes and cellular activity. Although deterministic models may capture mechanical features, local chemical fluctuations trigger random cell responses, which determine the overall evolution. Incorporating stochastic cellular behavior in macroscopic models of biological media is a challenging task. Herein, we propose hybrid models for bacterial biofilm growth, which couple a two phase solid/fluid mixture description of mechanical and chemical fields with a dynamic energy budget-based cellular automata treatment of bacterial activity. Thin film and plate approximations for the relevant interfaces allow us to obtain numerical solutions exhibiting behaviors observed in experiments, such as accelerated spread due to water intake from the environment, wrinkle formation, undulated contour development, and the appearance of inhomogeneous distributions of differentiated bacteria performing varied tasks.
