TL;DR: This work uses both colloidal experiments and computer simulations to progress beyond the zero-temperature limit to track one of the key parameters—the overlap distance between neighbouring particles—which vanishes at the T = 0 jamming transition, and finds that this structural feature retains a vestige of its T =0 behaviour and evolves in an unusual manner.

TL;DR: It is shown that particle density and interstitial air must both be considered in size segregation in mixtures of granular particles, and that this dependence does not follow a steady trend but is non-monotonic and sensitive to background air pressure.

TL;DR: A magnetic resonance imaging study of convection in a column of poppy seeds yielded data about the detailed shape of the convection rolls and the depth dependence of the conveyed velocity, which was found to decrease exponentially with depth.

TL;DR: There is a 1/N correction to the discrete jump in the contact number at the transition so that jammed packings exist only above isostaticity, demonstrating that the jamming transition can be considered a phase transition.

TL;DR: In this article, the temperature coefficient of the resistivity of metallic glasses is calculated starting from the same formalism which has been used to calculate the resistivities in liquid transition metals, and an explicit equation is derived for the temperature dependence which includes both effects due to the decrease in the static structure factor and those due to phonons.
