Query: Neutrino masses from lepton and quark mass relations and neutrino
  oscillations   Determining the absolute masses of neutrinos is of fundamental importance in
particle physics, nuclear physics, and astrophysics. We conjecture that
intrinsic mass relations exist between leptons and quarks. Using these
relations and neutrino oscillation data, we show that the inverted neutrino
mass hierarchy is strongly disfavored and estimate the absolute neutrino masses
to be m_{1}=0.21^{+1.70}_{-0.21} \times 10^{-4} {eV}, m_{2}=(8.7 \pm 0.1)
\times 10^{-3} {eV}, and m_{3}=(4.9 \pm 0.1) \times 10^{-2} {eV}.
