Abstract: Methods are provided for accurately predicting efficacy of chemotherapeutic agents. Methods of the invention increase the positive predictive value of chemosensitivity assays by assessing both the ability of a chemotherapeutic to destroy cells and the genetic propensity of those cells for resistance. Results obtained using methods of the invention provide insight into the in vivo effectiveness of a therapeutic, and lead to more effective chemotherapeutic treatment.

Abstract: A graphics system has a mode of operation in which real samples and virtual samples are generated for anti-aliasing pixels. Each virtual sample identifies a set of real samples associated with a common primitive that covers a virtual sample location within a pixel. The virtual samples provide additional coverage information that may be used to adjust the weights of real samples.

Abstract: In one embodiment, an apparatus includes an input port to receive a request to determine whether data units are stored in the cache, as well as an output port to generate look-ups for the pool of tags. The apparatus also includes a look-up filter coupled to the input and output ports, and operates to filter out superfluous look-ups for the data units, thereby forming filtered look-ups. Advantageously, the look-up filter can filter out superfluous look-ups to at least reduce the quantity of look-up operations associated with the request, thereby reducing stalling associated with multiple look-up operations. In a specific embodiment, the look-up filter can include a data unit grouping detector and a look-up suppressor.

Abstract: A system and method is provided for accessing information from a plurality of searchable information sources. The method includes the steps of: analyzing a user search query to determine a subject matter of the query; and selecting a sub-set of information from the plurality of information sources based upon the determined subject matter of the query. In further detailed embodiment, the analyzing step combines at least two methods of deriving the subject matter from the search query; and the method further includes the step of searching the information source(s) in the sub-set of information sources, substantially in parallel, for documents relevant to the search query. A system and method is also provided for searching a plurality of searchable information sources, where the information sources include at least one secure source.

Abstract: Systems and methods for scanning files for pestware on a protected computer are described. In one variation, locations of each of a plurality of files in a file storage device of the protected computer are identified while substantially circumventing an operating system of the protected computer. Information from each of the plurality of files is retrieved and analyzed so as to determine whether any of the plurality of files are potential pestware files. In variations, the operating system is circumvented while the information from each of the plurality of files is retrieved. In other variations, before information is retrieved from each of the plurality of files, a listing of the plurality of files is sorted according to the locations of the files on the storage device so as to reduce, even further, the time required to access the plurality of files.

Abstract: The present invention provides a method for efficiently converting methotrexate polyglutamates to methotrexate in a cellular extract by contacting the cellular extract with gamma glutamyl hydrolase under conditions suitable for efficient conversion of methotrexate polyglutamates to methotrexate.

Abstract: A graphics pipeline rasterizes primitives and generates a stream of groups of pixels, such as a stream of pixel quads. A tile coalesce unit received the stream of groups of pixels and generates pixel tiles for use by downstream pixel processing units. The pixel tiles facilitate hazard checks and transaction coherency.

Abstract: The present invention provides an improved system for determining factors secreted from patient cells, in which a tissue sample from the patient is harvested and cultured. One particularly important tissue sample preparation technique is the initial preparation of cohesive multicellular particulates of the tissue sample. The tissue sample technique of the present invention is also-useful in assaying expression and/or secretion of various markers, factors or antigens present on or produced by the cultured cells for diagnostic purposes and for using such expression to monitor the applicability of certain candidate therapeutic or chemotherapeutic agents and the progress of treatment with those agents.

Abstract: A radio frequency antenna system and high-speed digital data link are disclosed to, among other things, reduce electromagnetic interference (“EMI”) at relatively high data rates while reducing the manufacturing complexities associated with conventional data links. In one embodiment, a radio frequency (“RF”) antenna system includes an antenna and an RF radio coupled to the antenna for receiving wireless RF signals. In particular, the RF radio is configured to digitize RF signals at a fixed data rate to form digitized data signals and to apply the digitized data signals at a variable data rate to a high-speed digital link. The variable data rate distributes the signal energy of the digitized data signals over one or more bands of frequencies, thereby beneficially altering an EMI spectral profile describing emissions that develop as the digitized data signals are transported through a channel.
