Diagnostic testing systems and related methods employ actuation pressure-based control during fluid transfer within a test cartridge. A method of operating a cartridge to process a biological sample includes coupling an actuation port of the cartridge with a pump assembly of a portable analyzer. A transfer operation of the pump assembly induces airflow through the actuation port so as to displace an aliquot of the sample solution along a fluid channel. A control unit monitors a pressure signal indicative of a pressure of air displaced by the pump assembly. The transfer operation is stopped in response to a change in the pressure signal indicative of contact of the aliquot of the sample solution with a hydrophobic staging vent.

This disclosure describes systems, devices, and techniques related to generating audiences for media campaigns based on previous consumer behavior. In some examples, a query is received from at least one provider device. The query may indicate at least one characteristic of interactions between consumer accounts and items offered by an online marketplace. Audience identifiers can be retrieved from at least one database corresponding to the query. In some cases, the audience identifiers indicate a set of consumer accounts that have previously interacted with one or more items according to the characteristic(s) specified by the query. An indication of the audience identifiers can be output to the provider.
