Abstract: Systems for high-performance, low-latency database log mining applications. A method commences upon receiving a log mining query. The query specifies desired results that correspond to a prior logical state of the database system. A first type of processing entity is invoked to process contents of the redo stream by loading metadata into a data dictionary, and a second type of processing entity is invoked to construct metadata from the redo stream, wherein the constructed metadata pertains only database objects referenced in the query. During the time that the first type of processing entity is processing contents of the redo stream by loading metadata into a data dictionary, a process of a second type serves incoming queries using a subset of entries in the redo stream. When the data dictionary is completed, a switchover point is reached and thenceforth, incoming queries are served using the first type of processing entity.

Abstract: This invention relates to a colonic residue tagging system, formulation, kit and method for use in preparing an individual for a predetermined activity which requires tagging at least some colonic residue in a digestive tract such that a medically and/or diagnostically useful procedure can be performed on the digestive tract. Such predetermined activity includes, but is not limited to, colon screenings. In one alternative embodiment, a dietary regimen comprising low residue foods is coordinated with the colonic residue tagging regimen, prior to a predetermined activity, thereby resulting in tagged stool such that a medically or diagnostically useful procedure can be performed on the digestive tract. The present invention also provides an individual sufficient amounts of fluids and nutrition while minimizing the amount of stool formation prior to the predetermined activity.

Abstract: The present invention relates to contrast media having a low concentration of contrast agent (active ingredient) and/or low Hounsfield value for use in medical or diagnostic procedures, or for therapeutic use. In one alternative embodiment, the contrast media are comprised of a contrast agent, alone or in combination with a stabilizing agent or osmotic agent. The present invention is directed to a contrast media having a Hounsfield value less than 250. In another embodiment, the contrast media comprises a contrast agent, such as a less than 2% w/v barium-based compound. In another embodiment, the present invention also relates to formulations and methods for distending and imaging an anatomic segment of an individual.
