Abstract:
The invention relates to devices and methods for nanopore sequencing. The invention includes arrays of nanopores having incorporated electronic circuits, for example, in CMOS. In some cases, the arrays of nanopores comprise resistive openings for isolating the electronic signals for improved sequencing. Methods for controlling translocation of through the nanopore are disclosed.
Abstract:
Methods, devices, and systems for performing intermittent detection during analytical reactions are provided. Such methods facilitate collection of reaction data from disparate reaction times. Further, such methods are useful for reducing photo-induced damage of one or more reactants in an illuminated analytical reaction at a given reaction time. In preferred embodiments, the reaction mixture is subjected to at least one illuminated and non-illuminated period and allowed to proceed such that the time in which the reaction mixture is illuminated is less than a photo-induced damage threshold period.

Abstract:
The present invention is generally directed to powerful and flexible methods and systems for consensus sequence determination from replicate biomolecule sequence data. It is an object of the present invention to improve the accuracy of consensus biomolecule sequence determination from replicate sequence data by providing methods for assimilating replicate sequence into a final consensus sequence more accurately than any one-pass sequence analysis system.
Abstract:
A system and process for providing a transaction infrastructure for matching user demand for a commodity such as energy across multiple sources and levels of distribution.

Abstract:
Nucleic acid sequence determination is a method whereby peaks in data traces representing the detection of labeled nucleotides are classified as either noise or specific nucleotides. Embodiments are described herein that formulate this classification as a graph theory problem whereby graph edges encode peak characteristics. The graph can then be traversed to find the shortest path. Various embodiments formulate the graph in such a way as to minimize computational time. In various cases it is desirable that such classification allow for the possibility of mixed bases in the nucleotide sequence. Embodiments are described herein that address the classification of mixed-bases. Embodiments are also described that detail methods and systems for processing the data in order to make the classification step robust and reliable.
