A system includes a plurality of watchdog components. Each watchdog component is configured to receive a kick signal from its monitored function to determine whether the monitored function is active. Each watchdog component is further configured to receive a respective token from all watchdog components that the each watchdog component is connected to. The respective token determines whether its respective watchdog component has timed out. Each watchdog component is further configured to generate a token responsive to the kick signal and further responsive to the respective token from all watchdog component that the each watchdog component is connected to. Each watchdog component is further configured to transmit the generated token to the all watchdog components that the each watchdog component is connected to.

Technologies are described for generating, acquiring, transferring, and manipulating sets of interaction representations, where an interaction representation represents user interaction with content on a computer device, typically using a software application. The set can be represented as an interaction representation. To facilitate set creation, including adding items to a set, a request can be sent to an application to provide an interaction representation, such as an interaction representation of a current state of user-content interaction associated with the software application. Sets can be associated with different types, where the set type can determine whether, and what types, of interaction representations can be added to a set. Sets can be associated with expiration events, where the interaction representation for the set, and in some cases the component interaction representations, can be deleted upon the occurrence of the expiration event. In some cases, a set can be designated not to expire.

An example developer tools system provided by a messaging system includes a software development kit (SKD) engagement monitor that permits capturing app open events in third party resources (e.g., third party apps) that use the developer tools system. The SKD engagement monitor is configured to operate in a manner that preserves privacy of the third party developers and avoids conveying to the messaging system backend environment personally identifiable information (PII) about the third party resource usage.

Systems and methods for estimating a property of an error in a circuit implemented on an n-qubit quantum system are provided, where the circuit comprises a gate set that comprises a first subset () and a second subset () of elementary gates. The first subset comprises a third subset () of elementary gates each of which consists of an n-fold tensor product of a plurality of single qubit gates.

The procedure further comprises performing a measurement readout R. The procedure is repeated for one or more values of {right arrow over (T)} or one or more states ψ or one or more measurement readout procedures R, where m is a positive integer greater than 1, G is an element of the first subset of elementary gates, {right arrow over (T)}=(T.sub.1, . . . , T.sub.m, T.sub.m+1=I), and T.sub.1, . . . , T.sub.m are elements of , with the proviso that n>2.

The application relates to providing medical information in response to a query, in particular, although not exclusively, to a method of querying a medical database using voice recognition. According to an embodiment, there is provided a medical query answering apparatus that is configured to convert detected audio signals into a natural language data stream; determine from the natural language data stream whether a voice command for information relating to a medical device or a medicament has been issued by a user; in response to a positive determination, convert at least part of the natural language data stream into a query for querying a medical database; supply the query to the medical database and receive a response therefrom; and provide an audio output based at least in part on the response from the medical database.

Systems, methods, computer-readable media, and apparatuses for identifying and executing one or more interactive condition evaluation tests to generate an output are provided. In some examples, user information may be received by a system and one or more interactive condition evaluation tests may be identified. An instruction may be transmitted to a computing device of a user and executed on the computing device to enable functionality of one or more sensors that may be used in the identified tests. A user interface may be generated including instructions for executing the identified tests. Upon initiating a test, data may be collected from one or more sensors in the computing device. The data collected may be transmitted to the system and may be processed using one or more machine learning datasets to generate an output.

A method for execution by a query processing system includes determining a query request that indicates a plurality of operators, where the plurality of operators includes at least one relational algebra operator and further includes at least one non-relational operator. A query operator execution flow is generated from the query request that indicates a serialized ordering of the plurality of operators. A query resultant of the query is generated by facilitating execution of the query via a set of nodes of a database system that each perform a plurality of operator executions in accordance with the query operator execution flow, where a subset of the set of nodes each execute at least one operator execution corresponding to the at least one non-relational operator in accordance with the execution of the query.

Techniques for optimizing CPU usage in a host system based on VM guest OS power and performance management are provided. In one embodiment, a hypervisor of the host system can capture information from a VM guest OS that pertains to a target power or performance state set by the guest OS for a vCPU of the VM. The hypervisor can then perform, based on the captured information, one or more actions that align usage of host CPU resources by the vCPU with the target power or performance state.

Methods and systems for monitoring performance in a distributed storage system described. One example method includes identifying requests sent by clients to the distributed storage system, each request including request parameter values for request parameters; generating probe requests based on the identified requests, the probe requests including probe request parameter values for probe request parameter values, representing a statistical sample of the request parameters included in the identified requests; sending the generated probe requests to the distributed storage system over a network, wherein the distributed storage system is configured to perform preparations for servicing each probe request in response to receiving the probe request; receiving responses to the probe requests from the distributed storage system, and outputting at least one performance metric value measuring a current performance state of the distributed storage system based on the received responses.
