A study of B0-anti-B0 oscillations with full reconstructed B mesons with   the BABAR detector
  Time-dependent B0-anti-B0 flavor oscillations are studied in e+e- annihilation data collected with the BABAR detector at center-of-mass energies near the Upsilon(4S) resonance. We report a preliminary result for the time-dependent B0-anti-B0 oscillation frequency, Delta_md = 0.512 +/- 0.017 +/- 0.022 hbar ps^{-1}.
