1. Simulations and theory are being used to investigate the statistical mechanics of jammed particulate matter. JAMMED MATTER A slow shear flow is a applied to a jammed system of grains. Mobility and diffusivity measurements yield an effective temperature which is indeed very close to that obtained using a statistical ensemble of jammed configurations.

2. The network formed by the jammed configurations and their transition states is a “small-world” network with a scale-invariant topology. Each node in the network is a jammed state. The nodes are linked if there is transition state between them. The network has the same topological properties as other complex networks such as WWW, Internet, protein- protein interaction networks, and sociological networks.

3. Education  Students: two graduate students and four undergraduate students.  International collaborations: one exchange student from Fortaleza, Brazil, and one from ENS, France. International collaborations with Prof. Shlomo Havlin (Israel), Dr. Jorge Kurchan, (Paris) and Prof. Sam Edwards (UK).  Attraction and retention of minority students: 3 undergraduate minority students working in the lab from Physics, Chemical and Mechanical Engineering reflecting the interdisciplinary nature of our work.  Dissemination to a broader audience: Why does this  Translation of the web content to spanish “Porque algunas areniscas presentan franjas?” At: http://www.seed.slb.com/es/index.htm  Curriculum development: New graduate course: Granular Matter. Students are introduced to research earlier in their careers: a student project comparing experiments and simulation of sandpiles has been recently published in J. Stat. Phys. 3, 1-8 (2004). sandstone from Petra have stripes?
