Abstract: Functionalized twin base linkers (TBLs) bind to and deactivate viruses by preventing their entry into cells. Functionalization of TBLs allows them to specifically bind to surface proteins of viruses, where they form structures that limit virus entry into cells and prevent viruses from replicating.

Abstract: A system, neural network, and corresponding method generate 3D landmarks associated with an object in a 2D image. An embodiment is a system comprising a neural network detector configured to produce planar coordinates of landmarks at points of the object in the 2D image and a depth coordinate estimator. The planar coordinates include planar coordinate pairs. The depth coordinate estimator is configured to receive the 2D image and the planar coordinates and to estimate a depth coordinate for each planar coordinate pair of each landmark to generate the 3D landmarks. The system reduces network parameters from MB to KB and has better performance relative to state-of-the-art methods. The system may be configured to apply the 3D landmarks for face alignment, virtual face makeup, face recognition, eye gaze tracking, face synthesis, or other face related application.

Abstract: A computer-based system and corresponding computer-implemented method for validating a black-box model are provided. An initial question is transformed into at least one additional question by rephrasing the initial question based on an initial answer from the black-box model to the initial question. A consistency metric is produced based on consistency of the initial answer and respective additional answers received from the black-box model in response to the at least one additional question. The black-box model is validated based on the consistency metric produced.

Abstract: Methods are provided for estimating a pose of an infant using image analysis and artificial intelligence. A classifier is trained using a dataset containing hybrid synthetic and real infant pose data. Multi-stage invariant representation machine learning strategies are employed that transfer knowledge from adjacent domains of adult poses and synthetic infant images into a fine-tuned domain-adapted infant pose estimation model.
