  The "states-non-conserving" fermion density of states (DOS), deduced from the
specific heat of hole-doped cuprates, could arise from a Kondo or heavy
fermion-like DOS being suppressed by anti-ferromagnetic spin fluctuations. The
large Fermi surface predicted by band theory and observed experimentally, is
still expected for zero pseudogap, but with an effective mass corresponding to
a Kondo temperature ~ 800 K. A finite pseudogap could divide it into Fermi
arcs. Theoretical results for the asymmetric Anderson model can account for the
experimental Wilson ratio.
