We investigate the shell structure of bubble nuclei in simple phenomenological shell models and study their binding energy as a function of the radii and of the number of neutron and protons using Strutinsky’s method. Shell effects come about, on the one hand, by the high degeneracy of levels with large angular momentum and, on the other, by the big energy gaps between states with a different n...

Braneworld scenario especially of the Randall-Sundrum type 2) have recently attracted much attention. In particular, cosmological models in this scenario have been studied actively 3), 4). It has been shown that braneworld cosmology seems to be consistent with the 4-dimensional conventional cosmology at least on scales much lower than that corresponding to the brane tension, provided bulk Weyl ...

We investigate the effect of the quark-gluon to hadron transition at T⋆ ∼ 150 MeV on the evolution of primordial cosmological perturbations, in particular distortions of the HarrisonZel’dovich spectrum. If the phase transition is first order, the sound velocity vanishes during the transition. Thus, density perturbations fall freely for about a Hubble time. The primordial Harrison-Zel’dovich rms...

Deep anterior lamellar keratoplasty (DALK) is a surgical technique for cornea replacement, which the healthy host corneal endothelium is preserved. Keratoconus patients are those who benefit most from a successful DALK procedure, once the endothelium of these patients is usually normal and should therefore be maintained. Several studies comparing visual outcomes between penetrating keratoplasty...
