An online Gift Registry Service provides registration of information for a gift registrant and allows access to the registry by potential gift giver users. In addition, users can tag items of interest at participating Service Provider (SP) sites and the SP sites will register these items with the Gift Registry Service on the user's behalf. It further provides a streamlined checkout process for purchasing these gift items with the registered SP sites (e.g. World Wide Web sites) over a distributed public network. Users and Service Providers (SP) initially register with the Gift Registry Service and are provided additional functionality. For users, a reminder service is provided to notify individuals automatically upon the trigger of certain events, such as important dates or product sales from online merchants. In addition, there are various occasion planning services available such as distribution lists, discussion groups, and other related resources for multiple events including weddings, baby showers, etc. These other resources include sending out announcements, reserving halls, and contracting services of related businesses for the occasion. A distinct advantage of this system is that users can perform all the planning for the event online in the comfort of their home or office. Service Providers on the other hand, can register system notification messages to be triggered on pre-determined events. In addition, Service Providers can obtain marketing information to tailor their products and services.

The present invention provides an innovative technique for rapidly and accurately determining whether two audio samples match, as well as being immune to various kinds of transformations, such as playback speed variation. The relationship between the two audio samples is characterized by first matching certain fingerprint objects derived from the respective samples. A set (230) of fingerprint objects (231,232), each occurring at a particular location (242), is generated for each audio sample (210). Each location (242) is determined in dependence upon the content of the respective audio sample (210) and each fingerprint object (232) characterizes one or more local features (222) at or near the respective particular location (242). A relative value is next determined for each pair of matched fingerprint objects. A histogram of the relative values is then generated. If a statistically significant peak is found, the two audio samples can be characterized as substantially matching.

A method and system is provided for computing lithographic images that may take into account non-scalar effects such as lens birefringence, resist stack effects, tailored source polarizations, and blur effects of the mask and the resist. A generalized bilinear kernel is formed, which is independent of the mask transmission function, and which may then be treated using a decomposition to allow rapid computation of an image that includes such non-scalar effects. Weighted pre-images may be formed from a coherent sum of pre-computed convolutions of the dominant eigenfunctions of the generalized bilinear kernel with the appropriate mask polygon sectors. The image at a point may be formed from the incoherent sum of the weighted pre-images over all of the dominant eigenfunctions of the generalized bilinear kernel. The resulting image can then be used to perform model-based optical proximity correction (MBOPC).

A method and a system for extracting information from a natural language text corpus based on a natural language query are disclosed. In the method the natural language text corpus is analyzed with respect to surface structure of word tokens and surface syntactic roles of constituents, and the analyzed natural language text corpus is then indexed and stored. Furthermore a natural language query is analyzed with respect to surface structure of word tokens and surface syntactic roles of constituents. From the analyzed natural language query one or more surface variants are then created, where these surface variants are equivalent to the natural language query with respect to lexical meaning of word tokens and surface syntactic roles of constituents. The surface variants are then compared with the indexed and stored analyzed natural language text corpus, and each portion of text comprising a string of word tokens that matches the any one of the surface variants or the natural language query is extracted from the indexed and stored analyzed natural language text corpus.

A method and apparatus are provided for measuring a parameter such as capillary pressure in porous media such as rock samples. The method comprises mounting a sample in a centrifuge such that different portions of the sample are spaced at different distances from the centrifuge axis, rotating the sample about the axis, measuring a first parameter in the different portions of the sample, and determining the value of a second parameter related to the force to which each portion is subjected due to rotation of the sample. In one embodiment, the first parameter is relative saturation of the sample as measured by MRI techniques, and the second parameter is capillary pressure.

In order to clustering documents, document vectors are formed for each of a plurality of documents of a corpus and plurality of reference vectors is generated. The document vectors are then compared to the reference vectors to generate similarity values for each of the document vectors. The document vectors are then sorted based on the similarity values for the document vectors to form a sorted list. Clusters are then formed based on the similarity between adjacent document vectors in the sorted list.

A method and system to measure misalignment error between two overlying or interlaced periodic structures are proposed. The overlying or interlaced periodic structures are illuminated by incident radiation, and the diffracted radiation of the incident radiation by the overlying or interlaced periodic structures are detected to provide an output signal. The misalignment between the overlying or interlaced periodic structures may then be determined from the output signal.

This invention provides a joint user clustering and power allocation method and a base station using the same. They are applicable to cooperative non-orthogonal multiple access (NOMA) systems. The method includes: sorting K user equipment devices (UEs) according to the K channel gains between the base station and the K UEs, and then establishing a strong user candidate group of K / 2 UEs and a weak user candidate group of K / 2 UEs; pairing each of the UEs in the strong user candidate group with each of the UEs in the weak user candidate group so as to divide the K UEs into K / 2 clusters, where the power allocation coefficients for each pair of UEs are also calculated during the paring process; and transmitting messages to the K UEs based on the calculated power allocation coefficients of the K / 2 clusters.

A method of fabricating a substrate includes forming a first conductive layer on a dielectric layer, forming a resist layer on the first conductive layer, and forming laser-ablated artifacts through the first resist layer, through the first conductive layer, and at least partially into the dielectric layer. A second conductive layer is formed within the laser-ablated artifacts. The laser-ablated artifacts are filled to form an overfilled circuit pattern. The resist layer and the first conductive layer are removed. Further, a portion of the overfilled circuit pattern is removed to form an embedded circuit pattern embedded within the dielectric layer.

Methods and kits for isolating RNA are provided that enable rapid RNA preparation from biological sources. In one aspect, RNA is isolated from difficult plant tissues and cells that contain high levels of secondary metabolites, without employing organic extraction or salt precipitation procedures. This method employs novel lysing and binding conditions to allow preparation of RNA free from secondary metabolites.
