Stress-induced anisotropy in granular materials: fabric, stiffness, and permeability

Matthew R. Kuhn, WaiChing Sun, Qi Wang

The loading of a granular material induces anisotropies of the particle arrangement (fabric) and of the material's strength, incremental stiffness, and permeability. Thirteen measu…

Albedos, Equilibrium Temperatures, and Surface Temperatures of Habitable Planets

Anthony D. Del Genio, Nancy Y. Kiang, Michael J. Way +8

The potential habitability of known exoplanets is often categorized by a nominal equilibrium temperature assuming a Bond albedo of either 0.3, similar to Earth, or 0. As an indicat…
