Matsukevich and Kuzmich (Reports, 22 October 2004, p. 663) claim to have produced several types of nearly maximally entangled states involving photons and atomic ensembles.
This comment points out an inaccurate formula relating the signal correlation coefficient to the mutual impedance and corrects it.

Recently, Parmigiani et al. [1] have presented core level photoemission data for Pt clusters on Teflon and SiO sub 2.
In a recent Physical Review Letter Himpsel et al. reported a photoabsorption study of the Ca 2p and F 1s absorption edges for a new monolayers of CaF sub 2 epitaxially grown on Si(111).
In the above paper, 1 Kleinman and Kisliuk state that "Fox and Li have investigated these configurations and the corresponding frequencies and losses for interferometers consisting of perfectly ref
In a recent letter M. Lilly et al have shown that a highly anisotropic state can arise in certain 2D electron systems. (This effect has also now been seen by another group).
In two recent papers, Leiberich and Wolfe reported hydrogen depth profiles of ion implanted garnet films, measured by elastic recoil analysis.
EXAFS measurements were done on Al(6)Mn in icosahedral and orthorhombic forms by Stern, Ma, and Bouldin [E.A. Stern, Y. Ma, C.E. Bouldin, Phys. Rev. Lett.
