Can Centauros or Chirons be the first observations of evaporating mini black holes?
We argue that the signals expected from the evaporation of mini black holes -
predicted in TeV-scale gravity models with large extra dimensions, and possibly
produced in ultra high energy collisions in the atmosphere - are quite similar
to the characteristics of the Centauro events, an old mystery of cosmic-ray
physics.Comment: 14 pages, LaTeX, one Table, uses rotate.sty and rotcapt.sty.

On the Need for Phenomenological Theory of P-Vortices or Does Spaghetti Confinement Pattern Admit Condensed-Matter Analogies?
Usually the intuition from condensed-matter physics is used to provide ideas
for possible confinement mechanisms in gauge theories. Today, with a clear but
puzzling ``spaghetti'' confinement pattern, arising after a decade of lattice
computer experiments, which implies formation of a fluctuating net of peculiar
magnetic vortices rather than condensation of the homogeneously distributed
magnetic monopoles, the time is coming to reverse the logic and search for
similar patterns in condensed matter systems. The main thing to look for in a
condensed matter setup is the simultaneous existence of narrow tubes
(-vortices or 1-branes) of direction-changing electric field and broader
tubes (Abrikosov lines) of magnetic field, a pattern dual to the one,
presumably underlying confinement in gluodynamics. As a possible place for this
search we suggest systems with coexisting charge-density waves and
superconductivity.Comment: 20 pages, 7 figures; to be published in ZhET
