Recently, as a result of the report of the Beasley Committee to Bell Laboratories, Lucent Technologies, several papers on which J. H. Schön was the lead author have been retracted. Another paper (1) that was published by Science was not formally analyzed by the Beasley Committee. Although we recognize that some parts of this paper may remain valid, we note that key parts depend on and cite results or methods derived from two of the already retracted papers (2, 3). We therefore advise the scientific community that the validity of all of the results in this paper cannot be established.
