Abstract: Embodiments relate to a method of fabricating a nano-sized structure in a resin element by nanoimprint lithography (NIL). The method reduces adhesive failure during NIL demolding by inhibiting polymerization at the interface between the resin element and the template. The template includes a polymerization inhibiting compound. The method includes pressing the template onto the resin element (or the resin element onto the template) to form the nano-sized structure in the resin element. The method also including diffusing the polymerization inhibiting compound from the template to the resin element, e.g., by holding them together for a period of time. A layer of the polymerization inhibiting compound is therefore formed at an interface of the template and resin element. The polymerization inhibiting compound inhibits polymerization at the interface. After the diffusion, the resin element is cured. Then the template is removed from the resin element.

Abstract: To maintain user interest, the social networking system determines whether a particular user is interested in posting original broadcast feed stories to the social networking system during a session. Specifically, the social networking system determines a likelihood of a user posting an original broadcast feed story during the session. If the likelihood of the user posting an original broadcast feed story is above a threshold, the social networking system may encourage the user to post an original broadcast feed story by displaying original broadcast feed stories posted by other users to the user in a feed provided to the user. Specifically, the feed may contain more original broadcast feed stories posted by other users or the original broadcast feed stories posted by other users may be ranked higher in the feed than a feed provided to the user if the likelihood was below the threshold.

Abstract: A system includes at least two base stations that emit light beams to illuminate an area for positional tracking objects in the area. A base station emits at least two light beams that rotate around a rotation axis at a rotational speed unique to the base station. Responsive to being illuminated by the light beams emitted by the at least two base stations, an object being tracked generates illumination data. The system determines which illumination data corresponds to one of multiple base stations by analyzing the illumination data over time. The system analyzes the illumination data corresponding to one base station to determine an orientation and/or position of the object relative to that base station.
