    摘要： Joint classification functionality is provided for natural language call routing (NLCR) or other type of natural language processing (NLP) application implemented in a communication system switch or other processor-based device. The processor-based device is configured to identify a plurality of words contained within a given communication, and to process the plurality of words utilizing a joint classifier. The joint classifier determines at least one category for the plurality of words based on application of a combination of word information and word class information to the plurality of words. Words and word classes utilized to provide the respective word information and word class information for use in the joint classifier may be selected using information gain based term selection.

    摘要： The present invention relates to apparatus, procedures and compositions for avoiding and reducing damage to low dielectric constant materials and other soft materials, such as Cu and Al, used in fabricating semiconductor devices. Damage reduction can be achieved by decreasing the role of mechanical abrasion in the CMP of these materials and increasing the role of chemical polishing, which can also improve material removal rates. Increasing the role of chemical polishing can be accomplished by creating a polishing slurry, which contains components that interact chemically with the surface to be polished. This slurry may or may not also contain soft abrasive particles, which replace the hard abrasive particles of conventional slurries. Use of soft abrasive particles can reduce the role of mechanical abrasion in the CMP process. Use of this slurry in CMP can reduce surface scratches and device damage.

    摘要： A method for the “one-pot” synthesis of insulin derivatives wherein insulin is modified at the &agr;-amino group of the PheB1 residue is described. The method comprises protecting the &agr;-amino group of the GlyA1 residue and the &egr;-amino group of the LysB29 residue by reaction of insulin with a cyclic anhydride of a dicarboxylic acid in the presence of a tertiary amine. The protected insulin is then reacted with an activated hydrophilic compound, preferably an activated polyethylene glycol, resulting in a conjugate of the hydrophilic compound coupled to the PheB1 residue of insulin. The protecting groups are then removed from the conjugate under mild acidic conditions, and the resulting insulin derivative can be purified by conventional methods. Monosubstituted insulin derivatives wherein polyethylene glycol or derivatives thereof or glycosides are coupled to the PheB1 residue of insulin are also described.
