Effective simulations of interacting active droplets
Scientific Reports, 2023 Droplets form a cornerstone of the spatiotemporal organization of biomolecules in cells. These droplets are controlled using physical processes like chemical reactions and imposed gradients, which are costly to simulate using traditional approaches, like

Self-attenuation of extreme events in Navier–Stokes turbulence
Nature Communications, 2020 Whether a turbulent flow would inevitably develop singular behavior at the smallest length scales is an ongoing intriguing debate. Using large-scale numerical simulations, Buaria et al.

Oscillatory rheotaxis of artificial swimmers in microchannels
Nature Communications, 2022 Biological and artificial microswimmers often navigate channels under external flow, where in many biomicroswimmers the active upstream motion is oscillatory. Here the authors demonstrate that regular, controllable, and reproducible oscillatory rheotaxis

Science, 2005 In origami, form follows the sequential spatial organization of folds. This requires continuous intervention and raises a natural question: Can origami arise through self-organization? We answer this affirmatively by examining the possible physical origin for the Miura-ori leaf-folding patterns that arise naturally in insect wings, leaves, and other ...

Kinneyia: a flow-induced anisotropic fossil pattern from ancient microbial mats
Frontiers in Materials, 2016 Kinneyia is the commonly-used term to describe a class of trace fossil that is strongly associated with microbial mats. The appearance of Kinneyia (or wrinkle-structures) in the fossil record has recently led to a number of possible mechanisms being ...

The statistical geometry of material loops in turbulence
Nature Communications, 2022 Turbulent flows are observed in atmosphere, ocean, and technology, with turbulent mixing due to stretching and folding of material elements. The authors analyze a geometric perspective of this process and uncover statistical properties of an ensemble of ...

Minimum entropy production by microswimmers with internal dissipation
Nature Communications, 2023 The energy dissipation and entropy production by self-propelled microswimmers differ profoundly from passive particles pulled by external forces.

Randomized Self-Organizing Map [PDF]
Neural Computation, 2021 We propose a variation of the self-organizing map algorithm by considering the random placement of neurons on a two-dimensional manifold, following a blue noise distribution from which various topologies can be derived. These topologies possess random (but controllable) discontinuities that allow for a more flexible self-organization, especially with ...
