Abstract: Methods and systems described in this disclosure receive a call from a caller, generate a first session through a first channel associated with the caller when the call is received and then send a request for authentication credentials to a device associated with the caller. In some embodiments, sending the request for authentication credentials generates a second session through a second channel associated with the caller. The caller can be authenticated to the first session using communication received during the second session through the second channel.

Abstract: A method and authentication mechanism is provided. A request is sent to authenticate a user of the application from a mobile device to an authentication server. The authentication server identifies a user profile for the user containing one or more authentication schemes available to authenticate the user. The authentication schemes comprise a direct scheme in which the user provides a password and a federated authentication scheme. The authentication server determines a favored authentication scheme from one or more authentication schemes available based on a policy associated with the user profile. The mobile device displays a menu showing the authentication schemes available to allow the user to select an authentication scheme. The favored authentication scheme is displayed ahead of a remainder of the authentication schemes. The authentication server verifies credentials for the user profile using the selected authentication scheme to authenticate the user.

Abstract: In a general aspect, a computing system is configured to execute a quantum approximate optimization algorithm. In some aspects, a control system identifies a pair of qubit devices in a quantum processor. The quantum processor includes a connection that provides coupling between the pair of qubit devices. ZZ coupling between the pair of qubit devices is activated to execute a cost function defined in the quantum approximate optimization algorithm. The cost function is associated with a maximum cut problem, and the ZZ coupling is activated by allowing the pair of qubits to evolve under a natural Hamiltonian for a time period ?. One or more of the pair of qubit devices is measured to obtain an output from an execution of the quantum approximate optimization algorithm.

A signal delivery system in communication with the control system and the quantum processor receives control signals to execute the control sequences, and the control signals are applied to the respective cores in the quantum processor.

Abstract: A pumping method for use with a pump set to deliver fluid through the pump set to a subject includes determining a duration of time for flushing the first fluid out of the pump set with a second fluid different from the first fluid. A compensated flow rate is calculated for delivering the first fluid through the pump set based on the duration of time for flushing the first fluid out of the pump set. The first fluid is delivered through the pump set at the compensated flow rate.

Abstract: In a general aspect, a superconducting quantum circuit system is modeled. In some aspects, a graph representing a quantum circuit system is generated. The graph includes vertices and edges; the edges represent circuit elements of the quantum circuit system, and the vertices represent physical connections between the circuit elements. Inverse inductances, conductances, capacitances, and junction inverse inductances are assigned to respective edges of the graph based on a lumped-element approximation of the quantum circuit system. A coordinate system is determined based on the graph, and a matrix representation of the system is determined based on the coordinate system. A Hamiltonian for the quantum circuit system is determined using the matrix representation, and the quantum circuit system is simulated based on the Hamiltonian.

Abstract: A pumping apparatus for use with a pump set to deliver fluid through the pump set to a subject includes a pumping device capable of acting on the pump set to produce a fluid flow within the pump set. A controller is in communication with the pumping device for controlling operation of the pumping device in a feeding configuration and in a flushing configuration. The controller is adapted to store a selected flow rate and a desired fluid volume of a first fluid in the memory and at least one of a flush rate and flush volume of a second fluid. A flush time compensator is capable of being run for determining a compensated feeding configuration of the first fluid based on an amount of time the controller will operate the pump device in the flushing configuration and the desired fluid volume of the first fluid.

Abstract: Provided herein are methods, systems, and devices for detecting and/or identifying one or more specific microorganisms in a culture sample. Indicator particles, such as surface enhanced Raman spectroscopy (SERS)-active nanoparticles, each having associated therewith one or more specific binding members having an affinity for the one or more microorganisms of interest, can form a complex with specific microorganisms in the culture sample. Further, agitating magnetic capture particles also having associated therewith one or more specific binding members having an affinity for the one or more microorganisms of interest can be used to capture the microorganism-indicator particle complex and concentrate the complex in a localized area of an assay vessel for subsequent detection and identification. The complex can be dispersed, pelleted, and redispersed so that the culture sample can be retested a number of times during incubation so as to allow for real-time monitoring of the culture sample.

Abstract: A separating system (1) comprises a housing (60) sized to receive a stack of articles having at least one first article (12) stacked on top of a second article (10). The system (1) also includes a lifter (20) movable into a contact position adjacent a surface (13) on the at least one first article (12). The lifter (20) is adapted to apply a lifting force to the surface (13) to lift at least a portion of the first article (12) above the contact position. An extractor (40) moves the second article (10) away from the stack of articles after the at least one first article (12) has been lifted above the contact position by the lifter (20). The housing (60) prevents the at least one first article (12) from moving with the second article (10) when the second article (10) is moved by the extractor (40) and guides the stack of articles downward after the second article (10) is moved away.

Abstract: The subject disclosure relates to annotating data based on gestures. Gestures include user interaction with a client device or client software. Gestures are tracked and associated with data. In an aspect, client context associated with a gesture is also tracked. The gestures are then employed to determine a global term to associate with the data. In an aspect, a look-up table comprising a pre-defined relationship between gestures and a global term can be employed. In another aspect, an inference component employ context information in conjunction with the tracked gestures to determine a global term to assign to data. After a global term is determined for data based on a gesture, an annotation file for the data can be created associating the data with the global term.
