Query: Measurement of the wrong-sign decays D0 -> K+ pi- pi0 and D0 -> K+ pi-
  pi+ pi-, and search for CP violation   Using 281 fb^-1 of data from the Belle experiment recorded at or near the
Upsilon(4S) resonance, we have measured the rates of the ``wrong-sign'' decays
D0 -> K+ pi- pi0 and D0 -> K+ pi- pi+ pi- relative to those of the
Cabibbo-favored decays D0 -> K- pi+ pi0 and D0 -> K- pi+ pi+ pi-. These
wrong-sign decays proceed via a doubly Cabibbo-suppressed amplitude or via
D0-D0bar mixing; the latter has not yet been observed. We obtain
R_WS(Kpipi0)=[0.229 +/-0.017(stat.) +0.013-0.009(sys.)]% and R_WS(K3pi)=[0.320
+/-0.019(stat.) +0.018-0.013(sys.)]%. The CP asymmetries are measured to be
-0.006 +/- 0.053 and -0.018 +/- 0.044 for the K+ pi- pi0 and K+ pi- pi+ pi-
final states, respectively.
