Among the Active Galactic Nuclei (AGN) that have suffered type mutations, the classically classified Seyfert 2 NGC 7582 recently found at a Seyfert 1 stage, is perhaps one of the most puzzling cases, since it defies a well supported case for unification. We investigate the possibility that this type transition, common to other 12 AGN, is driven by supernovae (SN) exploding in a nuclear/circumnu...

Recent numerical results for a model describing dispersive transport in rice piles are explained by mapping the model to the depinning transition of an interface that is dragged at one end through a random medium. The average velocity of transport vanishes with system size L as < v >∼ L2−D ∼ L−0.23, and the avalanche size distribution exponent τ = 2 − 1/D ≃ 1.55, where D ≃ 2.23 from interface d...

We show that the large mixing between νµ and ντ observed by the SuperKamiokande collaboration is a quite natural prediction in a large class of seesaw models. This large mixing is basically due to the unparallel family structure suggested from the observed mass hierarchies in quark and lepton mass matrices. We show that the unparallel family structure is automatically realized in " coset-space ...

We describe briefly new program for SUSY masses calculations. The main distinction of our program is that we start to solve the renormalization group equations for soft SUSY breaking parameters for SU(5) SUSY GUT model from Planck scale M P L = 2.4 · 10 18 Gev. Our program works also for large tan(β). We find that for m 0 ≤ 0.5 · m 1 2 the effects of the evolution from Planck scale to GUT scale...
