The Dnd (DNA degradation) phenotype, reflecting a novel DNA modification by sulfur in Streptomyces lividans 1326, was strongly aggravated when one (dndB) of the five genes (dndABCDE) controlling it was mutated. Electrophoretic banding patterns of a plasmid (pHZ209), reflecting DNA degradation, displayed a clear change from a preferential modification site in strain 1326 to more random modificat...

SUMMARY Chordwise pressure distributions were measured at several spanwise stations on a two-dimensional model wing fitted with a plain-hinged, trailing-edge flap, at a Reynolds number of 1.9 x IO6 based on chord. The flap was divided into two parts and was deflected to a maximum of 5'. When the flaps were deflected differentially, the transition from a pressure distribution characteristic of t...

Neumann et al. (Reports, 6 June 2008, p. 1326) recently reported the preparation of multiparticle entanglement among single spins in diamond. However, two of the system's nuclear eigenstates are incorrectly described as product states when they are inherently entangled. Consequently, three of the six states reported, namely the odd-parity Bell states and the W state, were not actually produced.
