Part of Special Issue " Tsunami hazard from slope instability " Abstract. Recent experimental and theoretical work on the dynamics of submarine debris flows is summarized. Hy-droplaning was first discovered in laboratory flows and later shown to likely occur in natural debris flows as well. It is a prime mechanism for explaining the extremely long runout(More)
I study a lattice stochastic model of a mutating population sensitive to the influence of a fluctuating environment. The dynamics of the population stressed by linear and periodic disturbances is investigated. In agreement with previous studies of nonspatial models, I find a critical rate of change in the environmental variable beyond which the population(More)
A microscopic, quantum mechanical model for neutron vortices in the crust of a neutron star is presented. After a brief introduction to the Bogoliubov-de Gennes equations, which form the basis for our calculations, we present results for density distributions , vortex core sizes and vortex energies, both for an isolated neutron vortex and for the case when(More)
Electron – impurity scattering in the crust of neutron stars may be a relevant mechanism in delaying the cooling and in enhancing the decay of the pulsar's magnetic field. Extending previous work, in the present note I investigate the physics of the interfaces between layers in the crust of an isolated neutron star. The calculations confirm the possible(More)
Ammonoids are a group of extinct mollusks belonging to the same class of the living genus Nautilus (cephalopoda). In both Nautili and ammonoids, the (usually planospiral) shell is divided into chambers separated by septa that, during their lifetime, are filled with gas at atmospheric pressure. The intersection of septa with the external shell generates a(More)
We present a simple model of adaptive radiation in evolution based on species competition. Competition is found to promote species divergence and branching, and to dampen the net species production. In the model simulations, high taxonomic diversification and branching take place during the beginning of the radiation. The results show striking similarities(More)
