Abstract: An apparatus for detecting a substance comprising a direct analysis in real time apparatus; a neutral excluder; a mass spectrometer; and a vessel in. The apparatus may also comprise a separator, a gas, an alcohol, a filter, and a pump. The apparatus may also comprise electrodes in communication with the direct analysis in real time apparatus and the neutral excluder. A method for detecting a substance comprising contacting the substance with a direct analysis in real time apparatus ion stream; forming an ion and a neutral particle; flowing the ion and the neutral particle into a neutral excluder; contacting the ion and the neutral particle with a gas; and flowing the ion into a mass spectrometer.

Abstract: A vertical farming structure having vertical grow towers and associated conveyance mechanisms for moving the vertical grow towers through a controlled environment, while being exposed to controlled conditions, such as lighting, airflow, humidity and nutritional support. The present disclosure describes a reciprocating cam mechanism that provides a cost-efficient mechanism for conveying vertical grow towers in the controlled environment. The reciprocating cam mechanism can be arranged to increase the spacing of the grow towers as they are conveyed through the controlled environment to index the crops growing on the towers. The present disclosure also describes a tower shuttle mechanism that provides operational flexibility by decoupling the loading and unloading operations of the grow towers from the vertical farming structure and, therefore, allowing multiple grow towers to be extracted for harvesting in a batch process before loading new grow towers into the vertical farming structure in a separate process.

Abstract: Examples provide methods and apparatus for controlling a DC bias current in an RF amplifier. In one example where the RF amplifier is implemented on an amplifier die, a reference voltage is produced across a reference resistor implemented on the amplifier die, the DC bias current is measured, and a current controller, which is implemented on a controller die that is separate from the amplifier die, operates a feedback loop using the reference voltage to control a level of the DC bias current.

Abstract: This disclosure relates to systems and methods for searching names using name clusters. A method includes training a supervised machine learning system to learn a connection strength between a member and peers of the member; clustering the member with the peers in response to a threshold number of profile similarities between the member and the peers and the connection strength between the member and the peers being above a connection strength threshold value; and applying an unsupervised machine learning system using output from the supervised machine learning system and the clustering to generate a connection between the member and at least one of the peers.

Abstract: Systems and methods for ranking search results based on members' posting activity and content are disclosed. The social networking system receives a search request for at least one member profile and retrieves member profiles in response to the search request. For a member profile in the member profiles, the social networking system identifies at least one submitted content item associated with the member profile and analyzes the at least one submitted content item to determine topics associated with the at least one submitted content item. The social networking system generates a topic similarity score for the member profile based on a comparison of the topics and a topic of interest associated with the search request. The social networking system ranks the member profiles based on generated topic similarity scores. The social networking system selects at least one member profile based on the member profile ranking.

Abstract: A content delivery system coupled to a computer network can provide large volumes of content to large numbers of recipients. The content is collected into digests and individual articles to be sent in email via an email channel established by the content delivery system to the recipients through the computer network. Content producers submit content for aggregation into various email deliveries and submit initial scheduling information. The scheduling information may specify target characteristics of preferred recipients of the content as well as general and initial scheduling preferences for email delivery. The content delivery system utilizes the initial scheduling information as a starting point for scheduling email deliveries. The system measures levels of content interaction by the recipients to gauge corresponding interest levels in the content.

Abstract: A cup with cooling and liquid preservation system, where a set made up of a water holding container/base (1) holds the coupling of a cylindrical body cup (7) (8) in such a way as to cause the closing of the set through its upper brim (11), while maintaining an open inner space in the mentioned container/base (1). The joined set is then placed in the freezer, and, after unscrewing both parts; a crust of ice (G) around the cylindrical body (8) of the cup (7) is formed, which is then attached to the support (13). Thus a tulip-shape is formed, with its sides surrounded by a block of ice (G), exposed and supported to the lower support (13), allowing the ingestion of liquids like draft beer, and others at a constant cold temperature until the ice (G) melts. The water produced duly drains to the bottom of the support (13).
