  Helfrich-Hurault elastic instabilities driven by geometrical frustration

  The Helfrich-Hurault (HH) elastic instability is a well-known mechanism behind patterns that form as a result of strain upon liquid crystal systems with periodic ground states. In the HH model, layered structures undulate and buckle in response (...)

  Morphological computation and decentralized learning in a swarm of sterically interacting robots

  Whereas naturally occurring swarms thrive when crowded, physical interactions in robotic swarms are either avoided or carefully controlled, thus limiting their operational density. Here, we present a mechanical design rule that allows robots to (...)

  Linear Instability of Turbulent Channel Flow br

  Laminar-turbulent pattern formation is a distinctive feature of the intermittency regime in subcriticalplane shear flows. By performing extensive numerical simulations of the plane channel flow, we show thatthe pattern emerges from a spatial (...)

  Molecular Computation for Molecular Classification

  DNA as an informational polymer has, for the past 30 years, progressively become an essential molecule to rationally build chemical reaction networks endowed with powerful signal-processing capabilities. Whether influenced by the silicon world (...)

  Microscopic foundation of the mu(I) rheology for dense granular flows on inclined planes

  Macroscopic and microscopic properties of dense granular layers flowing down inclined planes are obtained from Discrete-Element-Method simulations for both frictionless and frictional grains. Three fundamental observations for dense granular (...)

  Cross-sections of doubly curved sheets as confined elastica

  Although thin films are typically manufactured in planar sheets or rolls, they are often forced into three-dimensional (3D) shapes, producing a plethora of structures across multiple length scales. To understand this complex response, previous (...)

  Nanoparticle Taylor Dispersion Near Charged Surfaces with an Open Boundary

  The dispersive spreading of microscopic particles in shear flows is influenced both by advection and thermal motion. At the nanoscale, interactions between such particles and their confining boundaries become unavoidable. We address the roles (...)

  Nonlinear decision-making with enzymatic neural networks

  >Artificial neural networks have revolutionized electronic computing. Similarly, molecular networks with neuromorphic architectures may enable molecular decision-making on a level comparable to gene regulatory networks1,2. Non-enzymatic (...)

  Elastohydrodynamic Relaxation of Soft and Deformable Microchannels

  Hydrodynamic flows in compliant channels are of great interest in physiology and microfluidics. In these situations, elastohydrodynamic coupling leads to (i) a nonlinear pressure-vs-flow-rate relation, strongly affecting the hydraulic (...)

  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 (...)
