  • Publication number: 20160042072
    Abstract: A method for personalizing content for a particular user in a computing system comprising a user interface configured to display content. The method comprises identifying a long term profile having one or more features in a feature set and a long term level of importance associated with each term in the feature set, identifying a short term profile having one or more features in the feature set and a short term level of importance associated with each term in the feature set, identifying input related to the display of the one or more content items on the user interface, and using the input to modify the short term level of importance and the long term level of importance associated with each term in the feature set to form a modified user interest set.

  • Patent number: 8962279
    Abstract: Methods for sequencing nucleic acids are presented. Sequencing is accomplished through the chemical amplification of the products of DNA synthesis and the detection of the chemically amplified products. In embodiments of the invention, a substrate is provided having a plurality of molecules of DNA to be sequenced attached and a plurality of molecules capable of chelating pyrophosphate ions attached, the DNA molecules to be sequenced are primed, and a next complementary nucleotide is incorporated and excised a plurality of times leading to the buildup of pyrophosphate ions locally around the DNA molecule to be sequenced. Pyrophosphate ions are captured by the substrate-attached chelators and electronically detected to determine the identity of the next complementary nucleic acid in the DNA molecule to be sequenced. Additionally, devices and methods are provided for detecting biomolecules through the detection of pyrophosphate ions.

  • Publication number: 20140342470
    Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.

  • Publication number: 20140274730
    Abstract: Embodiments of the present invention provide devices methods for sequencing DNA using arrays of reaction regions containing sensors to monitor changes in solutions or bound molecules contained in the reaction regions. Additional embodiments provide devices and methods for sequencing DNA using arrays of reaction regions that allow for optical monitoring of solutions in the reaction regions. Chemical amplification schemes that allow DNA to be sequenced in which multiple nucleotide addition reactions are performed to detect the incorporation of a base are disclosed. By sequencing DNA using parallel reactions contained in large arrays, DNA can be rapidly sequenced.
