Some theoretical issues related to the problem of variance reduction in numerical approaches for stochastic homogenization are examined. On some simple, yet representative cases, it is demonstrated… Expand

Enantiogenic microbiological reduction of acyclic 2,3-diketones readily yields enantiomeric or diastereoisomenc chiral diols with high enantiomeric excesses. Some a-hydroxyketones can also be… Expand
