Abstract: A crop prediction system performs various machine learning operations to predict crop production and to identify a set of farming operations that, if performed, optimize crop production. The crop prediction system uses crop prediction models trained using various machine learning operations based on geographic and agronomic information. Responsive to receiving a request from a grower, the crop prediction system can access information representation of a portion of land corresponding to the request, such as the location of the land and corresponding weather conditions and soil composition. The crop prediction system applies one or more crop prediction models to the access information to predict a crop production and identify an optimized set of farming operations for the grower to perform.

Abstract: Methods for predicting the development of sepsis in a subject at risk for developing sepsis are provided. In one method, features in a biomarker profile of the subject are evaluated. The subject is likely to develop sepsis if these features satisfy a particular value set. Methods for predicting the development of a stage of sepsis in a subject at risk for developing a stage of sepsis are provided. In one method, a plurality of features in a biomarker profile of the subject is evaluated. The subject is likely to have the stage of sepsis if these feature values satisfy a particular value set. Methods of diagnosing sepsis in a subject are provided. In one such method, a plurality of features in a biomarker profile of the subject is evaluated. The subject is likely to develop sepsis when the plurality of features satisfies a particular value set.

Abstract: The present disclosure describes one or more embodiment of devices for assisting femoral component placement in total knee arthroplasty. The device may include a distractor configured to provide a constant distracting force. The distractor may include a main body of the distractor, a tibial paddle fixedly connected to the main body, the tibial paddle configured to engage a top of a tibia, at least one femoral paddle configured to push against a bottom of a femur, a spring housing fixed on the main body of the distractor, and a coiled constant force spring disposed in the spring housing. The spring housing is attached to an outer end of the coiled constant force spring, and the coiled constant force spring is configured to apply the constant distracting force on the at least one femoral paddle. The device further includes a mechanical apparatus for locating an isometric point of the femur.

Abstract: Various wear resistance designs may be applied to a reactor configured to facilitate chemical reactions, and/or comminution using shockwaves created in a supersonic gaseous vortex. The reactor may include a rigid chamber having a substantially circular cross-section. A first gas inlet may be configured to introduce a high-velocity gas stream into the chamber. A first replaceable wear part may be disposed in the chamber to absorb wear impact caused by the gas stream. In some implementations, the first replaceable wear part may be a cylindrical rod continuously fed into the chamber. In some implementations, the first replaceable wear part may be coated with, or composed of, a catalytic material, and/or may be electrically isolated from the rest of the reactor. In some implementations, a second gas inlet may be disposed to steer the gas stream to a desired area within the chamber to even out the wear impact.

Abstract: Methane may be dissociated at low temperatures and/or pressures utilizing a reactor designed to generate shockwaves in a supersonic gaseous vortex. Within a preprocessing chamber, the methane may be pressurized to a pressure of 700 kPa or more, and heated to a temperature below a dissociation temperature of methane. The methane may be introduced as a gas stream substantially tangentially to an inner surface of a chamber of the reactor to effectuate a gaseous vortex rotating about a longitudinal axis within the chamber. The gas stream may be introduced using a nozzle that accelerates the gas stream to a supersonic velocity. A frequency of shockwaves emitted from the nozzle into the gaseous vortex may be controlled. Product gas and carbon byproduct may be emitted from the chamber of the reactor. The carbon byproduct may be separated out from the product gas using a gas/solid separator.
