Abstract: The present invention is directed to systems and methods for fast and accurate structural representation and comparison of proteins. Specifically, the present invention provides a method for retrieval of a candidate set of near structural neighbors or structurally similar proteins of a query protein. The method is based on a representation of a protein structure as a “bag of words”—a collection of small disjoint backbone protein fragments. The representation allows quick comparison procedures of the query protein structure to a large number of known protein structures obtained for example, from a repository or database of proteins.

Abstract: Methods, and systems, including computer programs encoded on computer-readable storage mediums, including a method for presenting a video content item in a first display area; concurrently presenting, with the video content item in the first display area, objects that are displayed during the presentation of the video content item in a second display area, wherein the objects persist in the second display area after the object is no longer displayed during the presentation of the video content item in the first display area; receiving an indication identifying one of the objects presented in the first display area or the second display area; and processing a tag associated with the object, the tag comprising a reference to a media item, wherein the processing comprises: accessing the media item referenced by the tag; and presenting the media item at least partially in the first display area or the second display area.

Abstract: An indication of an object included in a frame of a video content item is received. A tag is associated with the object, the tag including a reference to a media content item. An additional frame that includes the object is identified in the video content item. The tag is associated with the additional frame in the video content item.
