Abstract: Systems and methods for computing a causal uplift in performance of an output action for one or more treatment actions in parallel are described herein. In an embodiment, a server computer receives interaction data for a particular period of time which identifies a plurality of users and a plurality of actions that were performed by each user of the plurality of users through a particular graphical user interface during the particular period of time. The server computer uses the interaction data to generate a feature matrix of actions for each user, and a set of confounding variables included to minimize spurious correlations. The feature matrix is then used to train a machine learning system, using data identifying a user's performance or non-performance of each action as inputs and data identifying performance or non-performance of a target output action as the output.

Each of the one or more first spargers are positioned such that the first end is outside of the main exterior body and the second end is positioned in a lower portion of the riser section of the main exterior body. The one or more first spargers are configured to supply compressed gas to the riser section of the main exterior body. The system also includes one or more second spargers each having a first end and a second end opposite the first end.

Abstract: A composite billet includes an array of textured-powder bars in a geometry that is compatible with assembly and drawing of a billet with LAR˜1:1. A method is presented of compressing the bars suitable for the billet geometry in an inert gas environment. Methods of drawing of the billet control the deformation of the composite billet during area-reducing draw to fine wire so that the shape and registration of the constituent bars is preserved. Lastly a method is disclosed to fabricate a cable-in-conduit conductor containing the textured-powder Bi-2212/Ag wires that enables robust forming of windings and also provides in-cable containment of a buffer gas flow under high pressure during the high-temperature heat treatment of the winding that is required to produce optimum superconducting performance in the winding.

Abstract: In accordance with an embodiment, described herein is a system and method for heterogeneous database replication from a remote server, for example a remote database server. A capture process can be registered as a replication slave to the remote server, and configured to receive transaction event data from that server. Transaction log events associated with a modification to the database at the remote server can be processed, and output as change data, in a canonical format output, for use with one or more heterogeneous targets, for example a target database server or message queue. The process enables capture of transaction log events associated with database transactions at a remote server that may be located on a different computer or network, or within an access-restricted environment such as a cloud environment, without the need to create additional copies of its transaction logs.

Abstract: Provided herein are systems, methods and computer readable media for proving gift giving within a group. Consumers may register for a gift giving program, create a group and invite other consumers to participate. Group members may be randomly assigned to a group, or assigned to a group based on an invitation or indicated group. Relationships between gift givers and recipients within a group may be determined, such as in a randomized format. Gift givers may purchase a gift, such as a good or a promotion from a promotion and marketing service. The promotion and marketing service may assign the promotion to the recipient so that the recipient may redeem the promotion for a good, service, or experience. Promotions may be automatically purchased on behalf of a gift giver who fails to purchase the promotion by a gift-giving deadline.
