Abstract: This disclosure is related to improved security authentication frameworks for crowdsourced gaming systems that facilitate collaboration among multiple virtual participants over a network. In certain embodiments, an electronic gaming platform includes a geolocation authentication system that authenticates, verifies, and authorizes virtual user participants prior to accepting submissions in virtual multi-participant contests hosted by the electronic gaming platform. The geolocation authentication system can transition collaborative gaming applications operated by virtual user participants between a restricted functionality state that locks one or more functionalities pertaining to the virtual multi-participant contests hosted by the electronic platform and an unrestricted functionality state that unlocks one or more functionalities pertaining to the virtual multi-participant contests.

Abstract: A polyaxial pedicle screw includes a housing, a bone screw member, and an anvil. The bone screw member includes a head and a threaded shaft extending from the head. The head is selectively securable within the housing. The anvil is positionable within the housing adjacent to the head of the bone screw member when the anvil and the head of the bone screw member are positioned within the housing. The anvil may define one or more grooves in an outer surface of the anvil. The groove defines a flap that is flexibly attached to the anvil to enable the anvil to flex an amount sufficient to maintain the head of the bone screw in constant contact with the anvil when the bone screw member is moved relative to the anvil. A rod reducer may be secured to the polyaxial pedicle screw to secure a spinal rod within the housing.

Abstract: Embodiments provide for dynamic generation and updating of quote data objects using machine learning. An example apparatus is configured to receive a quote request and parse the quote request to extract one or more quote parameters. The example apparatus is further configured to determine, based at least in part the one or more quote parameters and by querying a plurality of repositories that are each updated periodically or in real-time, available inventory associated with the product identifier, and to determine a set of alternative quote values for the product identifier. The example apparatus is further configured to generate, using a first trained machine learning model and based at least in part on the available inventory and the set of alternative quote values, a first quote feature for the quote request and a confidence score, and to cause transmission of a quote data object to a user device.

Abstract: This invention is directed to a polymeric powder preferably a medical grade polymeric powder, for use in Selective Laser Sintering (SLS) for application fields including but not limited to medical, food, and pharmaceutical. The, preferably medical grade, polymer is biodegradable and can be used to manufacture objects such as medical implants and tissue scaffolds.
