Structure formation during the collapse of a dipolar atomic bose-einstein condensate... We observe regimes of both global collapse, where the system evolves to a highly elongated or flattened state depending on the sign of the dipolar interaction, and local collapse, which arises due to dynamically unstable phonon modes and leads to a periodic arrangement of density shells, disks, or stripes....
Seismic vulnerability assessment of clustered historical centers: fragility curves based on local collapse mechanisms analyses... The paperaims at evaluating the seismic vulnerability of historical clustered buildings on a urban scale, through theanalysis of local collapse mechanisms, carried out with a parametric approach....
Anisotropies of cosmic background radiation from a local collapseWe present an exact solution of the anisotropies of cosmic backgroundradiation (CBR) from a local collapse described by a spherical over-denseregion embedded in a flat universe, with the emphasis on the relationshipbetween the dipole $(\Delta {\sf T}/{\sf T})_d$ and ...
