20090204551Learning-Based Method for Estimating Costs and Statistics of Complex Operators in Continuous Queries - A learning-based method for estimating costs or statistics of an operator in a continuous query includes a cost estimation model learning procedure and a model applying procedure. The model learning procedure builds a cost estimation model from training data, and the applying procedure uses the model to estimate the cost associated with a given query. The learning procedure uses a feature extractor, a confidence adjustor and a cost estimator. The feature extractor collects relevant training data and obtains feature values. The extracted feature values are associated with costs and used to create the cost estimator. The extracted feature values, the associated costs, the cost estimator, and a user interface are used to create a confidence adjuster. When applying the confidence adjuster and the cost estimator to a continuous stream of data, the feature extractor extracts feature values from the data stream, uses the extracted feature values as input into the confidence adjuster to determine whether or not the cost estimator should be used, and if so, uses the extracted feature values as inputs into the cost estimator to obtain the desired cost values.08-13-2009

20090210953Identification of TRPML3 (MCOLN3) as a salty taste receptor and use in assays for identifying taste (salty) modulators and/or therapeutics that modulate sodium transport, absorption or excretion and/or aldosterone, and/or vasopressin production or release - The present invention relates to the elucidation that TRPML3 is involved in salty taste perception in primates including humans and likely other mammals and based thereon high-throughput mammalian and medium-throughput oocyte-based electrophysiological assays for identifying human TRPML3 modulators, preferably TRPML3 enhancers. Compounds that modulate TRPML3 function in the assay are expected to affect salty taste in humans. The inventive electrophysiological assays, such as the two-electrode voltage-clamp technique, facilitate the identification of compounds which specifically modulate human TRPML3. The assays of the invention provide a robust screen useful to detect compounds that facilitate (enhance) or inhibit TRPML3 function. Compounds that enhance or block TRPML3 channel activity should thereby modulate salty taste. In addition, these compounds may be used to regulate sodium excretion, urinary output and other biological functions relating to sodium levels and TRPML3 related functions.08-20-2009
