Abstract: Described is a technology by which topics corresponding to web pages are used in relevance ranking of those pages. Topics are extracted from each web page of a set of web pages that are found via a query. For example, text such as nouns may be extracted from the title, anchor texts and URL of a page, and used as the topics. The extracted topics from a page are used to compute a relevance score for that page based on an evaluation of that page's topics against the query. The pages are then ranked relative to one another based at least in part on the relevance score computed for each page, such as by determining a matching level for each page, ranking pages by each level, and ranking pages within each level. Also described is training a model to perform the relevance scoring and/or ranking.

Abstract: The invention provides a method for detecting the presence of altered serum proteins in an Hepatitis B Virus (HBV)-infected patient with liver inflammation, comprising: obtaining a sample of serum from the patient; subjecting the sample to protein gel electrophoresis to separate proteins contained therein; staining proteins separated on the electrophoresis gel with silver nitrate solution; scanning the images of stained proteins into an image analysis scanner to obtain gel images; comparing the gel images to control samples of electrophoresis gels prepared from serum of normal patient and serum of HBV-infected patient with liver inflammation to determine whether the sample of serum from the patient contains specific serum proteins. This invention also provides serum protein biomarkers for the diagnosis of patients with HBV infection and liver inflammation.

Abstract: A process useful for producing low density high mineral wool based acoustical panels with improved acoustical absorption properties using a water felting process is disclosed. The process includes forming a dilute slurry mixture including water, mineral wool, a thermoplastic binder and/or starch; and distributing the dilute slurry on a porous carrier to have the slurry dewatered to a base mat by gravity drainage to remove water by gravity. A vacuum is adjusted to gradually apply vacuum to the gravity dewatered base mat to further dewater the base mat without subjecting the mat to static pressure that would compress the base mat. The base mat is dried to form an acoustical ceiling product that has a low density and excellent acoustical absorption properties.

Abstract: A network address mapping system is described. The network address mapping system can identify a set of Web pages, collects information from the Web pages indicating geographical locations (“geolocations”), and correlate the geolocations with the network addresses from which the identified Web pages are served. The collected information can be weighted based on various factors, such as its relative position in a Web page. The collected information can then be used to identify a geolocation. The network mapping system can deduce geolocations for portions of ranges of network addresses based on the score, and can infer geolocations for other portions based on the deduced geolocations. This mapping can then be stored in a database and provided as a geomapping service. The network address mapping system is able to map network addresses to geographical locations.

Abstract: Techniques pertaining to a circuit architecture capable of controlling a current source to a predefined precision are disclosed. According to one aspect of the present invention, an automatic trimming circuit is proposed to automatically trim a current generated from a current generator or circuit in accordance with a reference current. The automatic trimming circuit includes a comparator, an ADC and a register. The comparator that may be implemented as a subtractor finds a difference between a generated current and a reference current. The difference is then digitized to an n-bit precision. A digital representation of the difference is then kept in a register and used subsequently correct or modify the generated current to produce a precisely controlled current.

Abstract: A learning system for a search ranking function model may include a computer program that iteratively refines the model using new queries and associated documents from an unlabeled training set. The unlabeled training set may include a set of queries for which the associated documents have not been labeled as “relevant” or otherwise labeled. The new queries may be selected based on a similarity to and an accuracy of each neighbor from a labeled training set, such as a labeled validation set. Upon selection, the documents associated with the new queries may be labeled. The new queries and their associated documents may be accumulated into a labeled training set, such as a labeled training set, and a refined model may be learned based on the augmented labeled training set. The model may be iteratively refined until it is determined that the model is adequate.

Abstract: A method and system for reading data from a link buffer for output to a display device. A link buffer read period is determined which balances a write throughput over a source video frame time and a read throughput over a display frame time. A threshold is determined indicating a required number of pixels stored in a link buffer prior to starting to read data out of the link buffer for a next line display. A read signal is issued when the link buffer read period ends and the threshold is reached.
