Query: Coulomb resummation for $b \bar b$ system near threshold and precision
  determination of $\al_s$ and $m_b$.   We analyze sum rules for the $\Upsilon$ system with resummation of threshold
effects on the basis of the nonrelativistic Coulomb approximation. We find for
the pole mass of the bottom quark $m_b=4.75\pm 0.04 GeV$ and for the strong
coupling constant $\al_s(M_Z)=0.118\pm 0.006$. The origin of the contradiction
between two recent estimates obtained within the same formal framework is
clarified.
