Abstract: In one embodiment, a method includes receiving, from a link-search interface of a client device, a search query from a first user of an online social network. The link-search interface is associated with a composer interface in which the first user is composing a first post. The method further includes searching a web index of an online social network to identify one or more external objects matching a search query. The web index identifies a plurality of external objects hosted by third-party systems that have been posted to the online social network, and each search result comprises a reference to the respective external object and a link to the external object. The method further includes embedding, in the first post, a link to a first external object referenced by a first search result selected by the first user.

Abstract: A method of prioritizing arrhythmia alarms based on one patient's perfusion level includes receiving arterial blood pressure, electrocardiogram heart rate, and arterial pulse rate values of the one patient during a same time window. Analyzing the set of blood pressure values to determine if an arrhythmia event is indicated, where if an arrhythmia event is indicated, the method includes calculating a systolic blood pressure (SBP) ratio, comparing the SBP ratio to a first predetermined threshold, and if the SBP ratio is less than or equal to the first predetermined threshold, then activating a non-perfusion alarm. If the SBP ratio is greater than the first predetermined threshold, then calculating a standard deviation of a rate differential between the heart rate and the pulse rate values, and if the standard deviation is greater than a second predetermined threshold, then activating the non-perfusion alarm. A system and non-transitory computer media is also presented.

Abstract: In one embodiment, a method includes receiving a search query. The method includes generating query commands based on the search query.

The method includes searching to identify a first set of objects that match the first query command, and a second set of objects associated that match the second query command. The method includes generating one or more search results and sending a search-results page to the client system of the first user for display.

Abstract: Techniques for context-based queryless presentation of items are described. Without receiving an explicit query, an inferred query is determined based on a first set of context signals associated with a triggering event. Items matching the inferred query are selected based on a second set of one or more context signals associated with the triggering event. One or more results items identifying the one or more matching items are caused to display. Result items may be displayed in association with an explanation that identifies context values used to select an item or one or more attributes of the item that are relevant to a user or the inferred query.

Abstract: Techniques for context-based queryless presentation of recommendations are described. Without receiving an explicit query, an inferred query is determined based on a first set of context signals associated with a recommendation triggering event. Items matching the inferred query are selected based on a second set of one or more context signals associated with the recommendation triggering event. One or more results items identifying the one or more matching items are caused to display. A result items may be displayed in association with an explanation that identifies context values used to select an item for recommendation or one or more attributes of the item that are relevant to a user or the inferred query.

Abstract: A control system for a combustor system including a plurality of can combustors, each can combustor accommodating combustion of a plurality of combustion fluids in a combustion chamber thereof is provided. The control system may include a calculator calculating: a) a pressure drop for each respective can combustor of the plurality of can combustors between a selected combustion fluid upstream of the combustion chamber and a combustion flow within the combustion chamber of the respective can combustor, and b) a differential between the respective pressure drop for each of the plurality of can combustors and an average pressure drop across all of the plurality of can combustors. The differentials identify can-to-can variation. A controller can modify a combustion parameter of at least one can combustor to reduce the differential for the at least one can combustor. The system can work iteratively to reduce can-to-can variation.
