    摘要： As provided herein objects from a source catalog, such as a provider's catalog, can be added to a target catalog, such as an enterprise master catalog, in a scalable manner utilizing catalog taxonomies. A baseline classifier determines probabilities for source objects to target catalog classes. Source objects can be assigned to those classes with probabilities that meet a desired threshold and meet a desired rate. A classification cost for target classes can be determined for respective unassigned source objects, which can comprise determining an assignment cost and separation cost for the source objects for respective desired target classes. The separation and assignment costs can be combined to determine the classification cost, and the unassigned source objects can be assigned to those classes having a desired classification cost.

    摘要： In one aspect, a method for forming CIGSSe-based thin films includes depositing at least two layers of particles on a substrate. At least one layer includes a CIGSSe particle having a chemical composition denoted by Cu(InI-xGax)(S1-ySey)2 where 0≦x ≦1 and 0≦y≦1. The particle layers are annealed individually or in combination to form a CIGSSe thin film having a composition profile along the depth of the film In addition, one or more of the particle layers may be also deposited on a pre-existing absorber and annealed to form a film having a composition profile along the depth of the film After depositing thin film precursor layers containing CIGSSe nanoparticles (and/or any other particles) on a suitable substrate in accordance with a desired concentration profile, a subsequent treatment under an Se and/or S containing atmosphere at elevated temperature may be used to convert the precursor layers into a CIGSSe absorber film In a further aspect, a method for forming multinary metal chalcogenide semiconductor layers directly on a substrate from a solution of precursors, includes depositing a plurality of metal chalcogenide particles onto a substrate to form a precursor film A species containing a metal, chalcogen, or combination thereof is dissolved in a solution containing one or more solvents to form a liquid chalcogen medium. The precursor film is contacted with the liquid chalcogen medium at a temperature of at least 50 C to form a multinary metal chalcogenide thin film

    摘要： A method, system, business method, and computer program product for retrieving and organizing networked data, wherein fetch rules and extraction rules enable a user to automatically collect and extract information from a remote network site. The fetch rules reproduce the interaction a client executes if interacting directly with the remote site, so a server cannot be shut out. The extraction rules allow the client, preferably via an applet, to glean relevant information from the acquired pages for presentation in a general interface. As an electronic commerce business method, information about remote site responsiveness, fetch rules, and extraction rules may be shared between server and client for a fee. The server accumulates vendor contacts, stores query rules, and provides common interface rules. The invention can gather statistics on vendor responsiveness and can resell information to vendors or others.

    摘要： Apparatus, and an associated method, for adaptively controlling filter characteristics of a filter forming part of a receive station, such as a mobile station operable in a cellular communication system. An adaptive parameter unit is provided with signal representations of signals that are to be applied to the filter element. The adaptive parameter unit, responsive to measurement or other analysis of the signal indicia, selects the filter characteristics to be exhibited by the filter. And, the filter characteristics are caused to be selected responsive thereto. Dynamic selection and reselection of the filter characteristics is effectuated in which the response time of the filter is minimized during good signal conditions and increased, to permit increased filter operations, during weak signal conditions.

    摘要： A privacy-preserving index system addresses the problem of providing a privacy-preserving search over distributed access-controlled content. Indexed documents can be readily reconstructed from inverted indexes used in the search. The privacy-preserving index system builds a centralized privacy-preserving index in conjunction with a distributed access-control enforcing search protocol. The privacy-preserving index utilizes a randomized algorithm for constructing a privacy-preserving index. The privacy-preserving index is strongly resilient to privacy breaches. The privacy-preserving index system allows content providers to maintain complete control in defining access groups and ensuring its compliance, and further allows system implementors to retain tunable knobs to balance privacy and efficiency concerns for their particular domains.
