Abstract: Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

Abstract: Described herein are system and method embodiments to improve word representation learning. Embodiments of a probabilistic prior may seamlessly integrate statistical disentanglement with word embedding. Different from previous deterministic methods, word embedding may be taken as a probabilistic generative model, and it enables imposing a prior that may identify independent factors generating word representation vectors. The probabilistic prior not only enhances the representation of word embedding, but also improves the model's robustness and stability. Furthermore, embodiments of the disclosed method may be flexibly plugged in various word embedding models. Extensive experimental results show that embodiments of the presented method may improve word representation on different tasks.

Abstract: Embodiments of a generative framework comprise cooperative learning of two generative flow models, in which the two models are iteratively updated based on the jointly synthesized examples. In one or more embodiments, the first flow model is a normalizing flow that transforms an initial simple density into a target density by applying a sequence of invertible transformations, and the second flow model is a Langevin flow that runs finite steps of gradient-based MCMC toward an energy-based model. In learning iterations, synthesized examples are generated by using a normalizing flow initialization followed by a short-run Langevin flow revision toward the current energy-based model. Then, the synthesized examples may be treated as fair samples from the energy-based model and the model parameters are updated, while the normalizing flow directly learns from the synthesized examples by maximizing the tractable likelihood. Also provided are both theoretical and empirical justifications for the embodiments.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station via a first instance of a periodic data burst, where the periodic data burst may include one or more uplink or downlink transmissions scheduled on a first bandwidth part (BWP).

The UE may operate, based on the determination, on one of the first BWP or a second BWP during at least a portion of a time period that extends from the expiration of the inactivity timer and a beginning of a second instance of the periodic data burst.

Abstract: Techniques for managing metadata storage units involve: in response to receiving, from a client, a request for allocating a target number of metadata storage units, determining a first number of available metadata storage units remaining in a metadata storage space of a storage system after the allocation is performed; and if the first number is not less than a reserved number, allocating the target number of metadata storage units from the metadata storage space for the client to use, wherein the reserved number is associated with a usage condition of the metadata storage units in the storage system. Accordingly, such techniques can effectively manage metadata and improve the performance of a system.

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.
