Space-time plots of bumps for a Gaussian threshold distribution. Simulations of (3) using as initial conditions the two different solutions shown in Fig. 10. Top: stable; bottom: unstable. Parameter values are \(\kappa=1\), \(\epsilon=0.01\), \(\sigma=1\), \(\alpha=5\), \(B=0.76\), \(\beta=3\) and \(h_{0}=0.05\)
