  Polymer-chain configurations in active and passive baths

  The configurations taken by polymers embedded in out-of-equilibrium baths may have broad implications in a variety of biological systems. As such, they have attracted considerable interest, particularly in simulation studies. Here we analyze (...)

  
  

• Analytical cell size distribution: lineage-population bias and parameter inference

  We derive analytical steady-state cell size distributions for size-controlled cells in single-lineage experiments, such as the mother machine, which are fundamentally different from batch cultures where populations of cells grow freely. For (...)

  
  

• A deep artificial neural network powered by enzymes

  Molecular networks have been developed that can classify complex mixtures of DNA sequences that cannot be categorized by a single linear classifier. To do this, artificial ’neurons’ powered by enzymes are wired together to form an architecture (...)

  Dynamics of a colloidal particle coupled to a Gaussian field: From a confinement-dependent to a non-linear memory

  The effective dynamics of a colloidal particle immersed in a complex medium is often described in terms of an overdamped linear Langevin equation for its velocity with a memory kernel which determines the effective (time-dependent) friction and (...)

  Frustrated ’run and tumble’ of swimming Escherichia coli bacteria in nematic liquid crystals

  In many situations, bacteria move in complex environments, as soils, oceans or the human gut-track, where carrier fluids show complex structures associated with non-Newtonian rheology. Many fundamental questions concerning the ability to (...)

  Enhanced dip coating on a soft substrate

  A solid, withdrawn from a wetting liquid bath, entrains a thin liquid film. This simple process, first described by Landau, Levich, and Derjaguin (LLD), is commonly observed in everyday life. It also plays a central role in liquid capture by (...)

  Active boundary layers in confined active nematics

  The role of boundary layers in conventional liquid crystals is commonly related to the mesogen anchoring on confining walls. In the classical view, anchoring enslaves the orientational field of the passive material under equilibrium conditions. (...)

  Elastic Instability of Cubic Blue Phase Nano Crystals in Curved Shells

  Many crystallization processes, including biomineralization and ice-freezing, occur in small and curved volumes, where surface curvature can strain the crystal, leading to unusual configurations and defect formation. The role of curvature on (...)

  Overload wave-memory induces amnesia of a self-propelled particle

  Information storage is a key element of autonomous, out-of-equilibrium dynamics, especially for biological and synthetic active matter. In synthetic active matter however, the implementation of internal memory in self-propelled systems is often (...)

  Adaptive strategies in Kelly’s horse races model

  We formulate an adaptive version of Kelly’s horse model in which the gambler learns from past race results using Bayesian inference. We characterize the cost of this gambling strategy and we analyze the asymptotic scaling of the difference (...)
