Abstract: The present invention provides a tissue-engineering vascular graft (TEVG) comprising a biodegradable scaffold, and a plurality of stem cell-derived vascular smooth muscle cells (VSMCs), wherein the plurality of stem cell-derived VSMCs are seeded on the biodegradable synthetic polymer scaffold and are cultured under mechanical and biochemical stimulation.

Abstract: In one embodiment, a method includes, receiving a request, from a client system of a first user, to access a marketplace including products offered for sale by a second user. The method includes, by the computing device, filtering a set of product listings based on multiple respective product-listing embeddings and a content-interaction embedding associated with the first user. Each product listing includes a description of one of the products in the marketplace. The method includes ranking each product listing in the filtered set based at least on a product-score representing a likelihood of the first user interacting with the respective product. The product-score is based on interaction information associated with the first user, product information associated with the product, and sparse information associated with the first user. The method includes sending, to the client system of the first user, a subset of the ranked product listings.

Abstract: Systems, methods, and non-transitory computer readable media are configured to provide a plurality of control modes to selectively control display of content items in a news feed of a user. One or more content items associated with a predetermined entity selected by the user or a predetermined event are identified based on at least one control mode of the plurality of control modes. Display of at least one content item of the one or more content items is provided in the news feed of the user.
