20090194483 | MICROFLUIDIC DEVICE HAVING MONOLITHIC SEPARATION MEDIUM AND METHOD OF USE - A microfluidic device, a device including the microfluidic device and methods of operation are described. | 08-06-2009 |
20100131563 | System and methods for automatic clustering of ranked and categorized search objects - A search results page includes multiple search lists generated by multiple clustering operations applied to an initial match set of documents selected based on a user query. A first result list is constructed by clustering a top-n set of documents by primary domain address and sorting based on extrinsic ranking factors such that the first list includes a ranked and ordered list of primary domain linked anchor text. A second result list is constructed by clustering the top-n set of documents based on a unified ranked occurrence of keywords within the top-n set of documents. The generated second list contains a plurality of cluster class references with each of the cluster class reference including a ranked ordered sub-list of the keywords occurring within the top-n set of documents and respectively associated with the cluster class reference, each of the keywords of the ranked ordered sub-lists including linking references to a corresponding one of the top-n set of documents. A third result list is constructed by clustering the top-n set of documents based on a ranked frequency of occurrence of internally linked anchor texts. The generated third result list includes the top-n set of the internally linked anchor texts and respective ranked and ordered sub-lists of linking references to primary domain Web-pages containing the corresponding one of the internally linked anchor texts. | 05-27-2010 |
20100193702 | TANDEM IONIZER ION SOURCE FOR MASS SPECTROMETER AND METHOD OF USE - An ion source a first ionizer comprising: an electrospray needle comprising a tip; and a conduit disposed annularly about the needle and configured to pass an inert gas in proximity of the tip to nebulize a fluid emerging from the tip, the nebulized fluid comprising analytes and a mobile phase. The ion source comprises a capillary in tandem with the first ionizer and configured to receive the droplets; a heater configured to heat the capillary to a temperature at which mobile phase vaporizes; and a second ionizer in tandem with the capillary and configured to receive the vaporized mobile phase and the analytes. A method is also described. | 08-05-2010 |
