  • Publication number: 20150024378
    Abstract: Methods for analyzing DNA-containing samples are provided. The methods can comprise isolating a single genomic equivalent of DNA from the DNA-containing sample to provide a single isolated DNA molecule. The single isolated DNA molecule can be subjected to amplification conditions in the presence of one or more sets of unique molecularly tagged primers to provide one or more amplicons. Any spurious allelic sequences generated during the amplification process are tagged with an identical molecular tag. The methods can also include a step of determining the sequence of the one or more amplicons, in which the majority sequence for each code is selected as the sequence of the single original encapsulated target. The DNA-containing sample can be a forensic sample (e.g., mixed contributor sample), a fetal genetic screening sample, or a biological cell.

  • Patent number: 8775437
    Abstract: Concepts and technologies are described herein for dynamically reranking search results based upon source authority. A search query is received and analyzed. One or more topics are identified in the search query. An authority index is searched to identify authoritative sources for content relating to the identified topic(s). Promoted results corresponding to content generated by the authoritative sources relating to the identified topics are obtained. The promoted results can be presented to an entity requesting the search, or injected into search results. Contribution dimensions associated with the promoted results can be determined, and filters based upon the contribution dimensions can be generated and used by an entity to dynamically manipulate the search results.

  • Patent number: 8260789
    Abstract: Concepts and technologies are described herein for authority ranking for real time and social search. An authority index configured to store data relating to sources is generated. Data relating to the sources, including an authority value, are generated and stored at the authority index. The authority value may be defined as a function of source, topic, and point of view (“POV”), as well as other data, if desired, and may be determined based upon one or more ranking functions. The ranking functions are determined, and data corresponding to the ranking functions is obtained. Each of the ranking functions may be weighted according to a weighting function, a confidence value or interval, one or more time functions, and/or other methods. The obtained authority value may be used for affecting ranking of search results or for other purposes.

  • Publication number: 20090005254
    Abstract: The invention describes a method for the identification of compounds which bind to a target component of a bio-chemical system or modulate the activity of the target, comprising the steps of: a) compartmentalising the compounds into micro-capsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.
