Abstract: A delivery system for delivering, adjusting, and/or recapturing a stent-valve includes an inner shaft and an expandable stent-valve coupled to the inner shaft. The stent-valve has an upper portion, a lower portion, and a valve. The delivery system also includes a distal sheath disposed over at least the lower portion, a proximal sheath disposed over at least the upper portion, and at least one cinching member coupled to the stent-valve and extending through one of the inner shaft, the distal sheath, or the proximal sheath. The upper and lower portions of the stent-valve are configured to move to an expanded configuration when the proximal and distal sheaths are withdrawn, respectively. After at least a portion of the stent-valve has been moved to the expanded configuration, the at least one cinching member is configured to at least partially radially compress at least a portion of the stent-valve.

Abstract: This document describes systems and techniques that enable continuous personalization of face authentication. In aspects, an authentication system associated with a network includes an authentication manager. The authentication manager receives an embedding representing image data associated with a user's face. The authentication manager generates a confidence score based on the embedding. Further, the authentication manager updates previously enrolled embeddings with the embedding based on the confidence score, the embedding meeting a clustering confidence threshold. Through such a technique, the authentication manager can alter the previously enrolled embeddings by which a future embedding is used to authenticate the user's face. By so doing, the techniques may provide more-accurate and successful user authentication over time.

Abstract: Described herein are devices and methods for generating new, lower-cost chloride solid electrolytes useful for lithium ion batteries. The devices replace higher cost, difficult to acquire elements such as Sc with less expensive, readily available elements such as Mg and Zr to form a highly conductive spinel structure. These materials may have a high ionic conductivity on the order of 0.23 mS/cm.
