]]>Packing of particles in confined environments is a common problem in multiple fields. Here, based on the two-dimensional Hertzian particle model, we study the packing of deformable spherical particles under compression and reveal the crucial role of stress as an ordering field in regulating particle...

]]>We extend previous work to describe a class of fluctuation relations (FRs) that emerge as a consequence of symmetries at the level of stochastic trajectories in Markov chains. We prove that given such a symmetry, and for a suitable dynamical observable, it is *always* possible to obtain a FR under a b...

]]>We consider a percolation process in which $k$ points separated by a distance proportional the system size $L$ simultaneously connect together ($k>1$), or a single point at the center of a system connects to the boundary ($k=1$), through adjacent connected points of a single cluster. These processes yiel...

The dynamic kurtosis (i.e., produced by the free wave component) is shown able to contribute essentially to the abnormally large values of t...

]]>The correlation diagrams of vibrational energy levels considering the Planck constant as a variable parameter have proven as a very useful tool to study vibrational molecular states, and more specifically in relation to the quantum manifestations of chaos in such dynamical systems. In this paper, we...

]]>Cellular behaviors such as migration, division, and differentiation rely on precise timing, and yet the molecular events that govern these behaviors are highly stochastic. We investigate regulatory strategies that decrease the timing noise of molecular events. Autoregulatory feedback increases noise...

]]>Spatially dispersed colonies of bacteria can communicate through the release and detection of signal molecules. In their experiment, the authors monitor biofluorescence induced in cells when the concentration of a molecular signal in a colony reaches a critical threshold. Simulations of a model with growth and diffusion reproduce the experimental data quite well.
