Abstract: Aspects of this disclosure relate to a front end architecture for selectively adding an external carrier aggregation band. A switch element can connect a radio frequency signal path to an antenna path through a frequency domain multiplexer, such as a diplexer, in a first mode. The switch element can connect the radio frequency path to the antenna path and bypass the frequency domain multiplexer in a second mode. The frequency domain multiplexer can be external to a front end module that include the radio frequency signal path. In the first mode, a front end system can support carrier aggregation with a band associated with circuitry implemented external to the front end module.

Abstract: One example method includes determining, based on criteria, a sustainability query for a supplier, where the criteria include standards identified by a client, types of suppliers specified by the client, and a maturity level of the supplier, prompting the supplier to respond to the sustainability query, receiving supplier responses to the sustainability query, creating a compliance score for the supplier based on the supplier responses to the sustainability query, and providing the compliance score to the client. Part, or all, of the method may be performed, for example, by an automated ESG mapping platform.

Abstract: An online system maintains a plurality of content items for presentation to users in one or more feeds of content items, the users including a plurality of content creators providing content items for presentation. The online system identifies a first set of content items provided by a content creator. The online system identifies a viewing set of users who viewed one or more content items in the first set of content items. The online system identifies a second set of content items provided by other content creators and viewed by the viewing set of users. The online system ranks the second set of content items and generates a feed of content items for the content creator including the ranked content items. The online system provides the generated feed for presentation.

Abstract: A fitment for use with a flexible container having a lower fitment member with a fluid conducting opening in a top surface and an upper fitment member with an upper fitment opening in an upper fitment bottom surface where the fluid conducting opening and the upper fitment opening form a fluid passageway or conduit. A wall of the flexible container is compressibly held between the top surface of the lower fitment member and the upper fitment bottom surface. The fitment may also include one or more additional walls of one or more additional flexible containers forming a bag-in-a-bag structure.

Abstract: A method of determining the total carbon dioxide concentration in plasma (TCO.sub.2 plasma) directly from a whole blood sample involves adjusting total carbon dioxide concentration measured in the whole blood sample (TCO.sub.2 whole blood) using a volume dilution factor (VDF) to give a value that is equivalent to TCO.sub.2 plasma.

Abstract: A CO.sub.2 electrode can be calibrated with two PCO.sub.2 calibration standard solutions having known pH values and known bicarbonate ion source concentrations. An O.sub.2 electrode can be calibrated using air as one calibration standard and a solution containing an excess of an O.sub.2 depleting agent as a second calibration standard.
