Abstract: A leather smart card is provided. The leather smart card includes a hard layer. A radio frequency identification (RFID) chip and a communication coil are disposed in the hard layer, and the RFID chip is electrically connected to the communication coil. The smart card further includes a leather layer and a soft layer. The soft layer is disposed on two back-to-back sides of the hard layer, and the leather layer is disposed on the side of the soft layer facing away from the hard layer. A material of the soft layer includes an ethylene-vinyl acetate copolymer, and a thickness of the soft layer is 0.2 mm to 0.5 mm. Consequently the leather smart card is not only aesthetic and waterproof, but also greatly improves comfort of using the smart card.

Abstract: A content distribution and optimization system that receives a plurality of event traffic bursts, generated by a first client computing device, in a first pod from a partition of a messaging bus. Messaging bus is partitioned based on a device identifier (ID) of the first client computing device and comprises a plurality of application launch timestamps. A filtering rule is configured for the device ID of the first client computing device for checking a rate limit of each event traffic burst. First set of event traffic bursts is blocked based on number of events exceeding a threshold value of rate limit of an event traffic burst generated by the first client computing device until a new fixed window is assigned. Event traffic communicated to a metrics aggregation controller is limited to pre-defined rate for the first client computing device. Enrichment of remaining second set of event traffic bursts is performed.

Abstract: Provided is a content distribution and optimization system that ingests raw event data from a client computing device at an entry point of a data pipeline service in accordance with a defined schema. Each payload of the raw event data comprises a first set of dimensional properties provided by the client computing device and/or a second set of dimensional properties added by the processor at the entry point. The raw event data is transmitted to a message bus pipeline for enrichment. A distinct use case is derived for each data consumer at a same time instant based on the enriched raw event data comprising same base event metrics associated with the base event. One or more payloads of the raw event data are transmitted to a stream-based messaging bus as raw video events. New metrics are derived based on raw video events for network selection and centralized alarming and reporting.

Abstract: The present invention disclosed a medical use of cucurbitane triterpenoids represented by the following formula and isolated from Momordica charantia L. of Cucurbitaceae family in the preparation of medications for prevention and treatment of diabetes and obesity. The above cucurbitane triterpenoids may be acted as a glucose uptake stimulator, an agonist for the translocation of glucose transporter 4 (GLUT4) to the cell membrane, and an activator of adenosine monophosphate-activated protein kinase (AMPK). They may have potential for the prevention and treatment of diabetes and obesity.

Abstract: The present invention provides 13,13a-dihydroberberine derivatives or their physiologically acceptable salts represented by the following formula, pharmaceutical compositions comprising the same, and uses thereof. The 13,13a-dihydroberberine derivatives have an activity of promoting glucose absorption in muscle cells, and the whole animal tests show that the present compounds have effects on improving glucose-tolerance and insulin-resistance, facilitating weight loss, relieving fatty liver and the like. Thus, the present compounds can be used in treating diabetes mellitus, adiposity, fatty liver and complications thereof induced by insulin resistance.
