We performed synchrotron x-ray diffraction and infrared (IR) experiments combined with evolutionary structure predictions and band structure calculations on Ag 2 Se to ß20 GPa. We present evidence for phase I (β-Ag 2 Se) as a potential three-dimensional topological insulator by its increase in optical band gap and the topologically nontrivial nature of its(More)
MOTIVATION A molecular interaction network can be viewed as a network in which genes with related functions are connected. Therefore, at a systems level, connections between individual genes in a molecular interaction network can be used to infer the collective functional linkages between biologically meaningful gene sets. RESULTS We present the human(More)
