Abstract: A device may obtain identification information concerning a clinical trial, and may obtain, based on the identification information, selection information concerning the clinical trial and input information concerning the clinical trial. The device may select at least one machine learning model, of a plurality of machine learning models, based on the selection information, and may process, using the at least one machine learning model, the input information to determine predicted rate of recruitment (RoR) information concerning the clinical trial.

Abstract: A lock includes a housing with a plug located in the housing. The plug is adapted to rotate in the housing about an axis. The lock also includes a moveable element comprising a first region with a first diameter, a second region with a second diameter that is less than the first diameter, and a third region with a third diameter that is less than the second diameter. The moveable element is located at least partly in the housing. The moveable element is adapted to move in an axis of motion substantially radial relative to the axis of the plug and to prevent rotation of the plug when the moveable element is in a first position along the axis of motion and to allow rotation of the plug when the moveable element is in a second position along the axis of motion.
