Considering the microscopic characteristics (vehicle speed, road length etc.) of links and macroscopic behaviors of traffic systems, we derive the critical flow generation rate in scale-free networks. And the dynamics of traffic congestion is studied numerically in this paper. It is shown that...

Some theoretical results concerning earthquake parameters are based on simplified seismic source models with uniform distributions of slips along a fault. Here two such results, the meaning of the apparent stress and the seismic energy vs. seismic moment relation, are revised by taking into...
