Abstract: The present invention provides an anti-rotational element, in the form of an adapter, a member integrated into the shaft or integrated into the head that increasing the front-to-back dimension of the stick compared to the side-to-side width dimension of the stick. The increased front-to-back dimension increases the anti-rotational torque that a lacrosse player, particularly a goalie, can generate. As a result, the goalie can prevent the stick from rotating in their hands when shots are off center relative to the longitudinal axis of the shaft thereby allowing the goalie to make saves that would otherwise result in a goal. The invention also aids in instructing goalies to avoid too tightly gripping the stick, which slows a goalies reaction time for a save.

Abstract: A pneumatic tire is formed from a tread rubber composition, which comprises a combination of at least two different solution polymerized styrene-butadiene rubbers (s-SBRs), each extended with oil, and a low Tg traction resin. The low Tg traction resin replaces high Tg traction and the rubber processing oil added during rubber compounding in conventional compounds. The low Tg traction resin is a hydrocarbon resin having a Tg between 100° C. to about 30° C.

Abstract: Systems and methods are provided for training and using a deep neural network with adaptively trained off-ramps for an early exit at an intermediate representation layer. The training includes, for respective intermediate representation layers of a sequence of intermediate representation layers, predicting a label based on the training data and comparing against a correct label. The training further includes generating a confidence value associated with the predicted label. The confidence value is based on optimizing an objective function that includes a weighted entropy of a probability distribution of the likelihood, weighted based on whether previous intermediate representation layer has accurately predicted the label. Use of the weighted entropy provides the training with a focus on predicting labels that the previous intermediate representation layers has performed poorly and not labels that have existed before the intermediate representation layer being trained.

Abstract: This invention is based upon the unexpected finding that a hydrocarbon traction resin can be dispersed into the oil used in making an oil extended emulsion and solution rubbers to attain improved performance characteristics. For instance, this technique allows for the hydrocarbon traction resin to be incorporated into the rubber at a higher level than would ordinarily be possible using conventional mixing techniques. In tire tread compounds this provides improved wet traction characteristics without compromising cured stiffness (dry traction) and ultimate properties (chip/chunk resistance). This technique can be used to incorporate a resin into virtually any synthetic rubber that can benefit from being oil extended. It is of particular value in making resin modified solution styrene-butadiene rubber (SSBR), emulsion styrene-butadiene rubber (ESBR), high cis-1.4-polybutadiene rubber, and synthetic polyisoprene rubber which are formulated for use in tire tread compounds.
