Abstract: A content provider can provide content, such as advertisements or other promotional material, to a recipient. A distribution system of the content provider can receive a query and select one or more advertisements and a user interface for presenting the advertisements based on the query, information associated with the user, a set of queries received from the user, and/or other information. A model for selecting the user interface can be generated by serving available user interfaces randomly or pseudo-randomly and monitoring user interaction with the served user interfaces. The model can be updated during regular use based on the performance of the user interfaces.

Abstract: Methods, systems and apparatus for quantum error correction. A layered representation of error propagation through quantum error detection circuits is constructed. The layered representation includes multiple line circuit layers that each represent a probability of local detection events in a quantum computing system associated with potential error processes in an execution of a quantum algorithm. To construct the layered representation, potential detection events associated with each potential error process occurring at quantum gates in the quantum circuit are determined. Lines are associated with each potential error process, the lines each connecting a potential detection event associated with the potential error process to another potential detection event associated with the same potential error process or a boundary of the quantum circuit. Similar lines are merged and used to construct unique line circuit layers.

Abstract: A system for controlling the test temperature of a unit-under-test inside a centrifuge while minimizing the exposure of attendant testing equipment to the test temperature. A barrier housing is emplaced around the unit-under-test to create a close test environment within which the test temperature can be achieved and maintained by the introduction of a thermal medium. The testing equipment is located on an opposite side of the barrier housing and outside of the close test environment but still within the centrifuge. A fixture negotiates the thermal medium from outside the centrifuge into the close test environment. The barrier housing may be an insulated clamshell housing which opens to fit around the unit-under-test and then closes to create the close test environment. The fixture may include a rotary joint in which the thermal medium moves into a central axis of the centrifuge, through a gimbal, and into the close test environment.

The systems and methods described herein include dynamically selecting user plane functions (UPFs) and/or dynamically placing UPFs at particular locations within the 5G network. In some examples, each UPF in the 5G network is statically placed, and the UPF used for communication between a source and destination is dynamically selected based on control plane data. In other examples, UPFs are dynamically placed, and the UPF used for communication is dynamically selected to reduce latency and/or resource usage based on control plane data. In other examples, UPFs are dynamically placed, and the UPF used for communication is dynamically selected to reduce latency and/or resource usage based on user plane data after the flow of packets has started between a source and destination.
