Abstract: A reward determined as part of a machine learning technique, such as reinforcement learning, may be used to control an adversarial agent in a simulation such that a component for controlling motion of the adversarial agent is trained to reduce the reward. Training the adversarial agent component may be subject to one or more constraints and/or may be balanced against one or more additional goals. Additionally or alternatively, the reward may be used to alter scenario data so that the scenario data reduces the reward, allowing the discovery of difficult scenarios and/or prospective events.

Abstract: The present invention discloses a method for producing ?-aminobutyric acid (GABA) by fermentation of native strain from raw material of Sayram Ketteki, comprising the following steps: dissolving the cow's milk in the normal saline for dilution to obtain diluents with different gradients first, coating the diluents in solid media for culture respectively, isolating single colonies and storing them in a glycerin cryopreservation tube for cryopreservation respectively; next, inoculating them in liquid medium for culture respectively, and inoculating them in fermentation medium for culture for culture after activation. The content of GABA product obtained by the present invention can reach 450 ?g/mL.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining that a first web resource responsive to a query includes content for which synchronized content is accessible by a native application installed on a user device, and in response to this determination generating a native application search result that includes native application request data that causes the native application installed on the user device to request the synchronized content and providing web resource search results and the native application search result to the user device, each respective web search result referencing a respective one of the web resources.
