Query: Giant conductance oscillations in a normal mesoscopic ring induced by an
  SNS Josephson current   A theoretical explanation of giant conductance oscillations observed in
normal mesoscopic rings with superconducting ``mirrors" is proposed. The effect
is due to resonant tuning of Andreev levels to the Fermi level, which enhances
the transparency of the system to the normal current. The mechanism is
demonstrated for a one-dimensional model system.
