Abstract: A system and method for tracking sports players to generate and apply receiver tracking metrics includes determining a catch/no-catch probability for a given pass route for a specific receiver using the player tracking data using a neural network model, determining a completion expected catch/no-catch estimation for a given pass route for a typical receiver using a classifier model and pass route data, calculating RTM sub-components of the receiver tracking metrics using the catch/no-catch probability and the completion expected catch/no-catch estimation, calculating corresponding weightings for each of the RTM sub-components, and calculating RTM scores by combining the RTM sub-components and weightings, the RTM scores including at least one of: open score, catch score, YAC score, and overall RTM score. In some embodiments, RTMs may be used to enhance or improve an end software application.

Abstract: The present invention is directed to a method for treating cystic fibrosis. The method comprises the steps of: identifying a patient suffering from cystic fibrosis, applying about 0.8-3 mL of a solution comprising about 18-65 mg/mL of denufosol into a medication reservoir of an nebulizer to achieve a target loading dose of denufosol of about 25-52 mg denufosol per dosing regimen, nebulizing the solution by passing through holes of an vibrating mesh device equipped with an oscillating membrane in the nebulizer, and delivering an inhaled respiratory dose of 20-33 mg to the lungs of the patient by inhalation within 3-9 minutes.

Abstract: A disc brake assembly for a motor vehicle includes a rotor, a bracket, a pair of brake pads slidably supported by the bracket for movement along a reference axis, and a caliper, also slidably supported by the bracket for movement along the reference axis, bridging the rotor periphery and operative to urge each brake pad into engagement with a respective friction surface of the rotor. A spring clip on the caliper includes a first pair of arms, each resiliently engaging a respective radially-disposed surface on the bracket to thereby releasably secure the spring clip to the caliper. The spring clip also includes a second pair of arms, each resiliently engaging a respective axially-disposed surface on the bracket to urge the outboard portion of the caliper along the reference axis away from the outboard friction surface of the rotor.
