🚨 New preprint 🚨 We introduce Generative Distribution Embeddings (GDEs) — a framework for learning representations of distributions, not just datapoints. GDEs enable multiscale modeling and come with elegant statistical theory and some miraculous geometric results! 🧵

Exciting news in fluid mixing! A new study from Yin et al. shows that when the swirling motion of a fluid (vorticity) is too closely linked to what it's mixing (like a pollutant), it actually slows down the mixing. Less connection means better mixing! @ go.aps.org/3YtK4KO

How do porous particles settle in density-stratified fluids? Size and shape matter, and in a way you might not expect! Very excited to share this work motivated by carbon sequestration in the ocean. More soon!
New @arxiv collab out from #harrislab @brownengin and @UNCFluidsLab: Smaller particles tend to settle slower. But in stratification the story can be more nuanced. When the stratifying solute can diffuse into the particle, the trend can reverse. arxiv.org/abs/2409.02419 🧵
Mixing viscous liquids efficiently in microfluidic systems is challenging due to slow diffusion. But now, scientists found that the Leidenfrost phenomenon, which forms a chaotic convection flow, can mix these liquids in milliseconds! Learn more: ow.ly/pktk50T7uNy
The importance of stupidity in scientific research
It’s amazing to see experimental evidence for a mechanism we conceived about a decade ago! Congratulations to @BoekhovenLab and @WebersGroup – this is surely just the beginning of an exciting scientific journey! 🎉
Frank Jülicher, @ZwickerGroup, Rabea Seyboldt, @HymanLab, @WebersGroup predicted such a size control in a theoretical framework. We have now verified that mechanism for the first time in an experimental system! nature.com/articles/nphys…
Crialesi-Esposito et al. explore how small droplets form in turbulent flows. Using high-resolution simulations, they find that the breakup of larger droplets drives internal dynamics, with high vorticity and dissipation being consequences, not causes. go.aps.org/3WmI8Bz
Announcing the WaterLily.jl paper (with code, of course)! physics.paperswithcode.com/paper/waterlil…
The WaterLily.jl preprint is now available on arXiv! 📰 arxiv.org/abs/2407.16032 WaterLily is a #CFD solver written in the #JuliaLang for incompressible flow and moving bodies. Together with @gabrielweymouth, we provide the main numerical methods, the design behind the 1/2
In our paper in Experiments in Fluids (doi.org/10.1007/s00348…) we present an experimental model that produces the main propulsive jet observed in the live fish fast-start. The structure acts flexibly when rotating in one direction and rigidly in the opposite direction.
