Jump at the onset of saltation

, 2011
We reveal a discontinuous transition in the saturated flux for aeolian saltation by simulating explicitly particle motion in turbulent flow. The discontinuity is followed by a coexistence interval with two metastable solutions.

Dynamic Tensile Strength of Dry and Saturated Hard Coal under Impact Loading

Energies, 2020
To evaluate the influence of water content on the hard coal dynamic behavior, the dynamic tensile properties of saturated coal Brazilian disk (BD) samples were studied using a split Hopkinson pressure bar system, and dry samples were also tested as a ...

Lattice packings with gap defects are not completely saturated [PDF]

, 2003
We show that a honeycomb circle packing in $\R^2$ with a linear gap defect cannot be completely saturated, no matter how narrow the gap is. The result is motivated by an open problem of G. Fejes T\'oth, G. Kuperberg, and W.

Nonequilibrium Critical Dynamics of a Three Species Monomer-Monomer Model

, 1996
We study a three species monomer-monomer catalytic surface reaction model with a reactive steady state bordered by three equivalent unreactive phases where the surface is saturated with one species.

Dietary modification of high density lipoprotein phospholipid and influence on cellular cholesterol efflux

Journal of Lipid Research, 1998
African green monkeys fed fat-specific diets served as a model to investigate the effect of phospholipid acyl chain modification on high density lipoprotein (HDL)-mediated cellular cholesterol efflux.
