Influence of Rotations on the Critical State of Soil Mechanics [PDF]
, 2010 The ability of grains to rotate can play a crucial role on the collective behavior of granular media. It has been observed in computer simulations that imposing a torque at the contacts modifies the force chains, making support chains less important.

Homology of the mapping class group for surfaces of genus 2 with boundary [PDF]
, 2008 We report on the computation of the integral homology of the mapping class group of genus g surfaces with one boundary curve and m punctures, when 2g + m is smaller than 6. In particular, it includes the genus 2 case with no or one puncture.Comment: This
