The Lagrangian description of turbulence is characterized by a unique conceptual simplicity
and by an immediate connection with the physics of dispersion and mixing. In this article, we …

Positron emission particle tracking (PEPT) is a technique which allows the high-resolution,
three-dimensional imaging of particulate and multiphase systems, including systems which …

A neural network particle finding algorithm and a new four-frame predictive tracking
algorithm are proposed for three-dimensional Lagrangian particle tracking (LPT). A …

From air-sea gas exchange, oil pollution, to bioreactors, the ubiquitous fragmentation of
bubbles/drops in turbulence has been modeled by relying on the classical Kolmogorov …

Ethanol electrooxidation was investigated at platinum based electrodes: Pt, Pt—Sn, Pt—Re
dispersed on a high surface area carbon powder. The atomic composition of the bimetallic …

Collective animal behaviour occurs at nearly every biological size scale, from single-celled
organisms to the largest animals on earth. It has long been known that models with simple …

Complex nonequilibrium systems are often effectively described by a “statistics of a
statistics”, in short, a “superstatistics”. We describe how to proceed from a given …

We introduce an original acoustic method to track the motion of tracer particles in high
Reynolds number turbulent flows. We present in detail the experimental technique and show …

Current understanding of collective behaviour in nature is based largely on models that
assume that identical agents obey the same interaction rules, but in reality interactions may …

Collective behaviour is typically thought to arise from individuals following fixed interaction
rules. The possibility that interaction rules may change under different circumstances has …
