Abstract: The present application relates to a pregabalin sustained release composition, comprising: (a) an active ingredient; (b) a matrix-forming agent; (c) a swelling agent; (d) a gelling agent; and optionally a filler. The pregabalin sustained release composition provided in the present application can rapidly swell in volume when exposed to aqueous medium until exceeding the dimeter of human gastric pyloric (13 mm). It thereby prolongs the gastric emptying time to increase the retention time of pregabalin in the stomach and enhances absorption of pregabalin in the small intestine and ascending colon. Moreover, the pregabalin sustained release composition provided herein achieves a sustained release for 24 h, which allows QD (once a day) administration, reduces administration number, and improves patient compliance.

Abstract: Example computer-implemented methods, media, and systems for serving machine learning (ML) models using an asynchronous input/output (I/O) mechanism are disclosed. One example method includes receiving a first request for running a ML model to provide a first prediction. A first green thread is generated responsive to the first request and executed on an operating system (OS) thread to send a first asynchronous remote procedure call (RPC) to a multiple producer single consumer (MPSC) channel. A second request for running the ML model to provide a second prediction is received. A second green thread is generated responsive to the second request and executed on the OS thread to send a second RPC to the MPSC channel. The first and the second asynchronous RPCs are scheduled using a first and a second blocking threads respectively, which are used by the ML model to generate the first prediction and the second prediction.

Abstract: The present disclosure describes a system with a power management device, a wakeup circuit, a battery management device, and a connector. During a powered down mode of operation, the battery management device can provide, via the connector, a bias voltage to the wakeup circuit. In response to a wakeup switch being activated, the battery management device can provide a power supply (e.g., from a battery) to the power management device. Benefits of the wakeup circuit include (1) a reduction of battery consumption—and thus improving battery lifetime—when the electronic system is in a powered down mode of operation because the wakeup circuit has lower number of active components compared to other designs and (2) a non-complex wakeup circuit design because one or more existing connector interconnects between the power management device and the battery management device can be re-used during electronic system's powered down mode of operation.
