TL;DR: It is found that morphogenesis at the Arabidopsis shoot apex depends on the microtubule cytoskeleton, which in turn is regulated by mechanical stress, and a feedback loop encompassing tissue morphology, stress patterns, and microtubules-mediated cellular properties is sufficient to account for the coordinated patterns of micro Tubule arrays observed in epidermal cells.
Journal ArticleDOI
Direct observation of the intermittency of intense vorticity filaments in turbulence.
TL;DR: Cavitation in a liquid seeded with bubbles is used as a new visualization technique to single out the regions of very low pressure of a fully developed turbulent flow and the sudden appearance of high vorticity filaments is observed.
Journal ArticleDOI
Dynamical phenomena: Walking and orbiting droplets
TL;DR: It is shown that bouncing droplets can be made to ‘walk’ at constant horizontal velocity on the liquid surface by increasing this acceleration, which yields a new type of localized state with particle–wave duality.
Journal ArticleDOI
Single-particle diffraction and interference at a macroscopic scale.
Yves Couder,Emmanuel Fort +1 more
TL;DR: A droplet bouncing on a vertically vibrated bath can become coupled to the surface wave it generates and become a "walker" moving at constant velocity on the interface, and diffraction or interference patterns are recovered in the histogram of the deviations of many successive walkers.
Journal ArticleDOI
From bouncing to floating: noncoalescence of drops on a fluid bath.
TL;DR: An analysis using lubrication theory accounts for most of the observations, showing that a steady regime where a drop can be kept bouncing for any length of time is found.
