Also disclosed a sampling device, a sampling system and a method of generating data associated with the collection of the samples of particulates. Also disclosed is a system and method for analysing the sample data to identify the particulates in the collected samples and their one or more characteristics which may be correlated with the surrounding environment.

Abstract: Systems and methods are provided for receiving a first plurality of media content items during a first time interval, identifying, from the first plurality of media content items, a first subset of media content items based on a first characteristic, and identifying, from the first subset of media content items, a second subset of media content items based on a second characteristic. The systems and methods are also provided for generating a first sequenced content collection including the first subset and the second subset and causing a first content collection interface to be displayed by the first computing device, the first content collection interface comprising the first sequenced content collection.

Abstract: Methods, computer-readable storage media, and apparatuses for surfacing content items in a messaging system. The methods may include storing a content item generated by a client device of a user, the user associated with the messaging system and determining a score to assign to the interaction and updating a resurface score associated with the content item with the score. The methods may further include determining whether to resurface the content item to the user based on the resurface score and causing to be displayed on a display of the client device a user interface comprising a user interface item for the user to display the content item. The methods may further include updating weights used to determine the scores based on interactions of the user with the resurfaced content items.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. Search results responsive to a query are identified including a first search result in a top set of search results, the first search result associated with a first entity. A first eligible content item is identified for presentation along with the search results, the first eligible content item associated with the first entity. A combined content item is identified that is a combination of the first search result and first eligible content item and is to be presented as a search result responsive to the query. The combined content item is augmented including: identifying entities related to the first entity, identifying content items that are associated with the related entities, selecting at least one identified content item, and using content from the selected content items to augment the combined content item.

Abstract: A method for generation of a video montage file from a plurality of media files is disclosed. The method includes selecting media files from a collection of media files based on a selection criterion, accessing audio feature information for an audio track, the audio feature information including timing information related to audio features of the audio track, generating a first video segment for a first time slot from a first media file, generating a second video segment for a second time slot from a second media file, creating a video montage file by adding the second video segment to the first video segment, and adding the audio track to the video montage file. The selection criterion may comprise a location, a time interval, or presences of the media files in a feed posted by the user on a messaging system or social media platform.
