Abstract: The present disclosure provides a method for requesting resources and a terminal. The terminal sends a first resource acquisition request for a target resource to each of first edge nodes, determines each of second edge nodes based on each first amount of the target resource returned by each of the first edge nodes, and sends a second resource acquisition request for the target resource to each of the second edge nodes.

Abstract: A method for tracking events of a client device is provided. The method may receiving, at a client device, a tracking script, wherein the tracking script provides instructions for the client device. The method may include tracking events of the client device as instructed by the tracking script. The method may include analyzing tracked events tracked as instructed by the tracking script. The method may include, upon occurrence of one or more analytical results corresponding to requirements indicated by the tracking script, sending tracking information to an analytics collection engine.

Abstract: The disclosure provides a nitrilase from Arabis alpina, which belongs to genus Arabis, family brassicaceae. The disclosure further provides the encoding gene, vector, recombinant bacterial strain, and the application in the manufacturing of (S)-3-cyano-5-methylhexanoic acid. The wet resting cells containing nitrilase Aa-Nit can kinetically resolve racemic IBSN at 1.2 M with a 42% conversion rate in 15 hr and >99% ee value. The disclosure provides a regio- and stereoselective method for the preparation of (S)-3-cyano-5-methylhexanoic acid. This method provides an atom economical, mild, environmental friendly industrial method to manufacture (S)-3-cyano-5-methylhexanoic acid.

Abstract: This invention relates to an improved process for the preparation of substantially pure, stable anhydrous gabapentin. Thus, cyclohexane 1,1-diacetic acid monoamide is first treated with NaOH/NaClO to form 3,3-pentamethylenebutyrolactam, which is treated with aqueous HCl solution under reflux to provide gabapentin HCl salt, which is then neutralized with NaOH followed by a dehydration step to provide substantially pure, storage-stable, pharmaceutical grade gabapentin.
