Abstract: A composition of matter for a layered ionic superconductor comprising a plurality of layers of ions and electronic interaction charges, and having a substantially improved superconducting transition temperature is described. An aspect of the composition includes a first layer comprising a plurality of alkali ions and cesium ions in particular that is adjacent to a second layer comprising a plurality of halogen ions and fluorine ions in particular. The first and second layers contain electronic interaction charges and are separated by a predetermined perpendicular distance. Crystalline structure, ionic properties, superconducting transition temperature, and superfluid density for several embodiments including companion ionic species are described and illustrated. Methods for preparing the several embodiments are provided.

Abstract: A methodology for retrieving textual data objects is disclosed. The information is treated in the statistical domain by presuming that there is an underlying, latent semantic structure in the usage of words in the data objects. Estimates to this latent structure are utilized to represent and retrieve objects. A user query is recouched in the new statistical domain and then processed in the computer system to extract the underlying meaning to respond to the query.
