Abstract: An online concierge system suggests subsequent search queries based on previous search queries and whether the previous search queries resulted in conversions. The online concierge system trains a machine learning model using previous delivery orders and whether initial and subsequent search queries in the previous delivery orders resulted in conversions. When the online concierge system receives a search query to identify one or more items from a customer, the online concierge system parses the search query into combinations of terms and identifies items related to the search query. In response to the search query resulting in a conversion, the online concierge system retrieves a conversion graph and presents a suggested subsequent search query based on the conversion graph. In response to the search query not resulting in a conversion, the online concierge system retrieves a non-conversion graph and presents a suggested subsequent search query based on the non-conversion graph.

Abstract: A network controller in an overlay network maintains collective sets of identity-based policies and identity mappings for onboarded users of the network for informed distribution to network elements across the network. As new users are onboarded, the controller identifies a site of the network at which the user was onboarded and determines identity mappings of the user and applicable policies for distribution to a network element at the identified site. The controller assigns index values to each identity and communicates the indices to network elements with the corresponding identity mappings and policies. The network elements encapsulate cross-site traffic with the index values corresponding to senders so recipient network elements can obtain the index value from encapsulation header formats, query the controller for the corresponding identity mappings, and apply policies to the traffic that are determined to be pertinent based on the sender's identity mappings obtained from the controller.

Abstract: A user equipment (UE) may receive a downlink message from a non-terrestrial network (NTN) which may include one or more sets of terrestrial network (TN) cell reselection information. The one or more sets of TN cell reselection information may further include location information corresponding to one or more cells of the TN. The UE may determine its location and, in response to receiving the downlink message, compare its location to the location information corresponding to the one or more cells of the TN. The UE may then select, based on the comparison, a set of the one or more sets of TN cell reselection information and further perform a cell reselection procedure based on the selection.

A system may first enable, by a controller, gas flow through a flow path of the gas distribution system. Afterwards, the system may receive data including pressure data and/or flow rate data associated with the flow path of the gas distribution system while gas flow is enabled through the flow path.

Responsive to determining that the flow path includes a malfunction, the system may determine a relative location of the malfunction within the flow path, with respect to a mass flow controller (MFC) or sensor within the flow path. The system may generate a report indicating whether the flow path includes a malfunction and a relative location of any determined malfunction.
