Abstract: A drug for antagonizing the replication of porcine reproductive and respiratory syndrome virus (PRRSV) and an application thereof. By using a viral infection test, a drug which antagonizes PRRSV—xanthohumol—is discovered for the first time from among a natural drug library of 386 plant sources. Xanthohumol can effectively inhibit PRRSV replication on both Marc-145 and PAM cells. Five xanthohumol derivatives having different molecular structures are artificially synthesized, and it is discovered that a derivative Xn-4 has the strongest inhibitory effect on virus replication in vitro. Test results of artificial infection and drug therapy in piglets show that the Xn-4 can effectively inhibit PRRSV viremia, relieve clinical symptoms of infected pigs, and significantly reduce lung inflammation and pathological damage.

Abstract: In an example, first entities are extracted from user profiles. Second entities are extracted from content information associated with content item. User-associated metrics associated with the first entities are determined based upon the user profiles and/or content events. First vector representations of the first entities and second vector representations of the second entities are processed to generate an attention distribution array. Each value of the attention distribution array represents, for a user interested in an entity of the first entities, a proportion of (i) entity-specific activity, of the user, related to an entity of the second entities relative to (ii) an entirety of activity of the user. An inferred activity distribution array is generated by applying the user-associated metrics to the attention distribution array. A filtered subset of activity distribution values is generated by pruning values from the inferred activity distribution array.
