The primary tool for predicting infectious disease spread and intervention effectiveness is
the mass action susceptible–infected–recovered model of Kermack & McKendrick. Its …

We numerically characterize the temporal regimes for solutal convection from almost first
contact to high dissolved solute concentration in a two-dimensional ideal porous layer for …

… A lower bound for the time at which perturbations can grow (the first time at which the
mean-square difference between the observed distribution of dissolved CO 2 and the pure …

Motivated by convection in the context of geological carbon dioxide sequestration, we present
the conditions for free, dissolution-driven convection in a horizontal, ideal porous layer …

A walker is a droplet of liquid that self-propels on the free surface of an oscillating bath of
the same liquid through feedback between the droplet and its wave field. We have studied …

A model for the dynamics of slender filaments of Herschel–Bulkley fluid is used to explore
viscoplastic dripping under gravity and thinning under controlled extension (liquid bridges). …

A droplet bouncing on the surface of a vertically vibrating liquid bath can walk horizontally,
guided by the waves it generates on each impact. This results in a self-propelled classical …

A collection of thin structures buckle, bend, and bump into each other when confined. This
contact can lead to the formation of patterns: hair will self-organize in curls; DNA strands will …

We derive an asymptotic reduced model for the extensional dynamics of long, slender,
axisymmetric threads of incompressible Herschel–Bulkley fluids. The model describes the …

… (4.1a−c) where U, V and H are functions of X ≡ ϵ3/2x and Y ≡ ϵ1/2y. By substituting these
definitions into the governing equations (2.1)–(2.3) and obtaining the equations at leading …
