Abstract: To enhance user engagement with a page posts maintained by a social networking system, a social networking system reviews posts associated with a page (e.g., a business or brand page) in a social networking system and measures a degree of user engagement with each post at one or more measures of exposure (e.g., time points or impressions). The social networking system then identifies posts for which the user engagement exceeds a threshold as high engagement or “hot” posts. An administrator associated with the page is notified of the identified high engagement post and can use this information for further promotion or boosting of the identified high engagement post.

Abstract: A multilayered feedthrough for an implantable medical device includes a substrate having a first edge, a second edge, and a substrate length. A plurality of traces is formed on the substrate and extends along the substrate length. The plurality of traces extends to the first and second edges of the substrate. An insulator layer is formed on the substrate and the plurality of traces. A ground plane layer is formed on the insulator layer.

Abstract: An implantable medical device is provided including a housing, an external circuit element extending outwardly from the housing, an internal circuit enclosed by the housing, a feedthrough array disposed along the housing having at least one filtered feedthrough and at least one unfiltered feedthrough, wherein the unfiltered feedthrough is adapted for connection to the outwardly extending circuit element; and including means for minimizing electromagnetic coupling between the filtered feedthrough and the unfiltered feedthrough.

Abstract: A determination of an equivalent series resistance (ESR) effect for high frequency filtering performance of a filtered feed-through assembly is described. A low frequency signal is introduced to a filtered feed-through assembly. ESR limit of the filtered feed-through is determined based on the low frequency signal.
