We numerically solve the steady-state equation and the stability spectrum for solidification in a channel. For a large range of parameters stable symmetric and stable parity-broken solutions coexist. The branches of parity-broken solutions are found to originate from the symmetric solutions...

This research examined the impact of community-policing programs on calls for service, Part 1 crime, total crime, and narcotics cases infour Houston neighborhoods. The methodology used time-senes analysis and examined lagged and dynamic effects. The analysis produced mixed results, indicating...

This article uses ARIMA and tobit analysis to examine the extent to which restrictive policies and intensified monitoring of "hot" pursuits by law enforcement officers induce these officers to ignore requirements that the initiation of such chases be communicated to their superiors and that...

Stable wrinkled fronts were often observed in experiments on fluid invasion into porous media, when the invaded phase is less viscous than the invading one. Recent experiments by a group at the Weizmann institute, show that capillary wetting of paper may also lead to rough self-affine fronts. A...

The extinction transition on a 1D heterogeneous substrate with diffusive correlations is studied. Diffusively correlated heterogeneity is shown to affect the location of the transition point, as the reactants adapt to the fluctuating environment. At the transition point the density decays like...
