Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for distributing digital components are described. One aspect features a digital component distribution system that can determine that a digital component that depicts content related to a particular subject can be distributed to a computing device. The system can use a data processing model and contextual information for the computing device to determine that it can include a remind-me-later user interface control with the digital component. In response to determining to include the remind-me-later user interface control, the system can modify the digital component to include the remind-me-later user interface control that, when interacted with by a user, causes the computing device to schedule a notification that reminds a user of the computing device of the subject of the digital component. The system can send the digital component with the remind-me-later user interface control to the computing device.

Abstract: The present disclosure provides techniques for presenting a reward impression. A computing system can receive, from a client device, a request to view the reward impression having a first time slot and a second time slot. The computing system can calculate a first conversion rate associated with a first content item being presented in the first time slot and a second conversion rate associated with a second content item being presented in the second time slot. The computing system can select, using the one or more machine-learned models based on the first conversion rate and the second conversion rate, the first content item and the second content item from a plurality of content items. The computing system can cause the presentation of the first content item in the first time slot and the second content item in the second time slot of the reward impression.

Abstract: Disclosed herein are surgical suture materials that facilitate the sustained delivery of releasable components. The suture materials are processed by the disclosed methods to create a layer of pores extending inward from the outer surface of the suture. Particularly, the surgical suture materials are swollen in a calcium-ion containing solution, then freeze-dried to create pores which can be filled with a releasable component for ultimate delivery to the tissue. In one particular embodiment, the suture has an outer sheath that defines a lumen. Elongated filaments extend through the lumen. This suture embodiment is processed by the disclosed methods to yield a surgical suture material with a porous outer sheath. The pores enable efficient loading of a releasable component into the lumen, facilitating sustained delivery of the releasable component from the suture.
