Abstract: In one embodiment, a method includes receiving, from a client device of a user of an online social network, an input from the user to access a card-stack interface, generating a plurality of cards, where each card comprises a suggested query referencing a query-domain associated with the online social network and one or more query-filters, and where each query-filter references one or more objects of the online social network, each card further comprising one or more search results corresponding to the suggested query, and each search result referencing an object of the online social network matching the suggested query of the card; and sending, to the client device in response to the input from the first user, the card-stack interface for display to the first user, wherein the card-stack interface comprises one or more of the generated cards

Abstract: In one embodiment, a method includes accessing a social graph that includes a number of nodes and edges connecting the nodes. Each of the edges between two of the nodes representing a single degree of separation between them. The nodes include a first node corresponding to a first user associated with an online social network and a plurality of second nodes that each correspond to a concept or a second user associated with the online social network. The method also includes generating a card cluster including a number of cards. Each card includes a suggested query referencing a query-domain associated with the online social network and zero or more query-filters. Each query-filter references one or more nodes of the plurality of nodes or one or more edges of the plurality of edges.

Abstract: The invention relates in part to a Sulfur standard gas in the ppb range in a matrix gas. The Sulfur standard gas is maintained in a cylinder under pressure sufficient to compress the majority of the Sulfur gas and into a liquid matrix.
