Violent expiratory events: on coughing and sneezing
Abstract Violent respiratory events such as coughs and sneezes play a key role in transferring respiratory diseases between infectious and susceptible individuals. We present the results of aExpand
The hydrodynamics of water strider locomotion
Water striders Gerridae are insects of characteristic length 1 cm and weight 10 dynes that reside on the surface of ponds, rivers, and the open ocean. Their weight is supported by the surface tensionExpand
Water entry of small hydrophobic spheres
We present the results of a combined experimental and theoretical investigation of the normal impact of hydrophobic spheres on a water surface. Particular attention is given to characterizing theExpand
The influence of surface tension on the circular hydraulic jump
We present the results of a combined theoretical and experimental investigation of the influence of surface tension $\sigma$ on the laminar circular hydraulic jump. An expression is deduced for theExpand
Hyperpycnal plume formation from riverine outflows with small sediment concentrations
A series of laboratory experiments has been conducted in order to elucidate the sediment-induced mixing processes accompanying riverine outflows; specifically, the discharge of a warm, fresh,Expand
Dynamic topography produced by lower crustal flow against rheological strength heterogeneities bordering the Tibetan Plateau
SUMMARY Dynamic stresses developed in the deep crust as a consequence of flow of weak lower crust may explain anomalously high topography and extensional structures localized along orogenic plateauExpand
Viscous sheet retraction
We present the results of a combined theoretical and numerical investigation of the rim-driven retraction of flat fluid sheets in both planar and circular geometries. Particular attention is given toExpand
Optimal concentrations in nectar feeding
Nectar drinkers must feed quickly and efficiently due to the threat of predation. While the sweetest nectar offers the greatest energetic rewards, the sharp increase of viscosity with sugarExpand
Freshwater Discharge, Sediment Transport, and Modeled Climate Impacts of the Final Drainage of Glacial Lake Agassiz
A cold event at around 8200 calendar years BP and the release, at around that time, of a huge freshwater outburst from ice-dammed glacial Lake Agassiz have lent support to the idea that the floodExpand
Drops walking on a vibrating bath: towards a hydrodynamic pilot-wave theory
Abstract We present the results of a combined experimental and theoretical investigation of droplets walking on a vertically vibrating fluid bath. Several walking states are reported, including pureExpand
