Abstract: Systems and methods are provided for receiving a request for lookalike data, the request for lookalike data comprising seed data and generating sample data from the seed data and from user data for a plurality of users, to use in a lookalike model training. The systems and methods further provide for capturing a snapshot of social graph data for a plurality of users and computing social graph features based on the seed data and the user data for the plurality of users, training a lookalike model based on the sample data and the computed social graph features to generate a trained lookalike model, generating a lookalike score for each user of the plurality of users in the user data using the trained lookalike model, and generating a list comprising a unique identifier for each user of the plurality of users and an associated lookalike score for each unique identifier.

Abstract: Metal fastener sticks wherein the individual fastening elements, such as staples, on the stick are secured together by a radiation cross-linked polymer, and which metal fastener stick is prepared by: coating the metal fastener stick with a solventless, radiation -curable, polymeric composition, such as an ultraviolet-curable formulation of an unsaturated resin, a monomer and a photo initiator; and curing the composition by exposing the composition to radiation, such as ultraviolet radiation, to provide a metal fastener stick wherein the individual fastener elements are secured together in the stick through the radiation cross-linked polymer.
