Before FAGG, WOLLMAN, and BEAM, Circuit Judges.
PER CURIAM.


1
Juan Manuel Hernandez-Nunez and Steven Lester Marts appeal their drug-related convictions.  Hernandez-Nunez's argument that the district court misinstructed the jury on the meaning of reasonable doubt is foreclosed by this court's contrary holdings.   See United States v. Harris, 974 F.2d 84, 85 (8th Cir. 1992);   United States v. Wilkerson, 691 F.2d 425, 427-28 (8th Cir. 1982).  Likewise, Marts's argument that the district court erroneously barred expert testimony about the impact on witness credibility of the substantial assistance reductions available under the sentencing guidelines is foreclosed by this court's contrary holding in  United States v. French, 12 F.3d 114, 116-17 (8th Cir. 1993).  We affirm.  See 8th Cir.  R. 47B.
