Stochastic Chaos in a Turbulent Swirling Flow

LML External Fellow Yuzuru Sato has recently reported the experimental evidence of the existence of stochastic chaos in a turbulent swirling flow.  Together with co-authors (D. Faranda, B. Saint-Michel, C. Wiertel, V. Padilla, B. Dubrulle, and F. Daviaud), he shows that the experimental attractor can be modeled by a random strange attractor in stochastic Duffing equations. The article is published in Physical Review Letters: Read more


A recipe for irreproducibility

During the 2016 LML summer school, Max and I ended up discussing the irreproducibility crisis in science, and that led to a draft manuscript, published today on the arXiv:1706.07773, see also this earlier blog post. Over the last few years several (apparently reproducible!) studies have come out that confirm the crisis. For instance, a survey of scientists, conducted by Nature, found that 70% of respondents had at some point tried but failed to reproduce a published result.

Percolation on trees as a Brownian excursion

Nicholas Moloney and Francesc Font-Clos have written up their calculation on the size of percolating clusters in branching processes. They exploit a mapping between continuum trees and Brownian excursions, and arrive at a diffusion equation with suitable boundary conditions. Read more
