Abstract: Systems, methods, and computer-readable storage media for aggregating media (and commentary on that media) into a topology. To do so, the system receives first content (and associated metadata) as well as second content (and associated metadata). The system then generates a topology based on a relationship between the first content and the second content, where the topology has a number of dimensions based on the metadata of the different pieces of content. The system then compares the topology and the metadata to previously stored topologies and/or metadata and, based on that comparison, executes a machine learning algorithm. The output of that machine learning algorithm includes predicted future changes to the topology, which the system uses to reduce the number of dimensions within the topology.

Abstract: Disclosed herein are methods, systems, and media for predicting a tertiary structure of a target RNA molecule comprising: creating a training data set comprising chemical mapping data for one or more of a first plurality of RNA molecules and tertiary structure data for one or more of a second plurality of RNA molecules; training a machine learning algorithm using the training data set; applying the trained machine learning algorithm to predict the tertiary structure of an the RNA molecule of interest; and outputting the predicted tertiary structure of the RNA molecule of interest.

Abstract: A system for positioning a patient before, during or after a medical procedure can include an arm assembly and a surgical drape for use with the arm assembly. The surgical drape can be configured to be placed around a surgical site where an operative procedure is to be conducted. The surgical drape includes a transparent viewing window, multiple handle covers, and an expandable opening on the top side of the surgical drape. Additionally, the surgical drape may also include adhesive components on the bottom side of the drape that may be independently removed in order to affix the drape around a surgical site.

Abstract: A system for positioning a patient before, during or after a medical procedure can include an arm assembly having a proximal end, an opposing distal end, and at least one joint therebetween. The joint can be configured to permit the distal end of the arm assembly to move with respect to the proximal end of the arm assembly. The proximal end of the arm assembly can be configured to be fixed with respect to a surgical table. The system can also include a ball joint mechanism attached to the distal end of the arm assembly and to a head support configured to support a patient's head. The ball joint mechanism can include a ball joint and a motor. Activation of the motor can permit or prevent movement of the ball joint.
