Abstract: A computer-implemented system is provided for configuring and managing a federation ecosystem implemented in a data query language and comprising a plurality of subgraphs. The system includes a sandbox registry in communication with the subgraphs. The sandbox registry is configured to test and verify changes to the subgraphs to ensure validity of the subgraphs. The system also includes a global registry in communication with the sandbox registry. The global registry is configured to register the subgraphs after the subgraphs are tested and verified by the sandbox registry. The system further includes a portal in communication with the global registry. The portal is configured to present to a user the subgraphs registered with the global registry and receive from the user instructions for combining two or more of the subgraphs to form at least one supergraph.

Abstract: A tiller including a walking element configured to move the tiller, a tine rotatable about a rotational axis; a first motor configured to drive the walking clement to move the tiller, and a counterweight, wherein the tine is disposed on a first side of the tiller and wherein the counterweight is disposed on a second side of the tiller opposite the first side.

Abstract: A quantum network may use long-lived quantum memories with optical interfaces incorporated into a scalable architecture. Color-center quantum emitters in diamond have emerged as a promising quantum-memory modality due to their optical properties and compatibility with scalable integration. Here, we disclose a cryogenically stable and network-compatible quantum-emitter module for use as a quantum memory. This quantum-emitter module includes a diamond microchiplet with quantum emitters in the form of silicon vacancies or other color centers. The diamond microchiplet is integrated with a silicon photonic integrated circuit (PIC), which is secured to a silicon bench with cryo-compatible epoxy. Waveguides in the PIC are butt-coupled to optical fibers in a silicon V-groove array, which is secured to the same silicon bench with more cryo-compatible epoxy.

Abstract: Systems and methods for synchronizing user activity across digital channels. The method includes receiving a first request corresponding to a first user activity on a first digital channel via a user device. The method also includes storing a first real-time activity record corresponding to the first request in a database. The method further includes updating a user profile based on the first real-time activity record. The method also includes receiving a second request corresponding to a second user activity on a second digital channel via the user device. The method further includes determining an intended transaction corresponding to the second request using a semantic knowledge graph. The method also includes generating a customized digital activity based on the user profile and determined intended transaction. The method further includes generating for display the customized digital activity on the user device.

Abstract: A rodent enclosure dimensioned in length, width and height so as to allow a rodent to run freely along the length of the enclosure, but not turn around without standing on its hind legs. The enclosure has a floor with bars extending transversely to allow access for a force sensor's probe from below. A force measurement device for use with the rodent enclosure to measure the tactile response of a rodent comprising a measurement probe connected to a device body. The probe has a tip which can be engaged with a rodent's paw through the floor of the enclosure. The device body has a fixed body part and a rotatable body part arranged to allow relative rotation between them. A rotation sensor detects the relative rotation and outputs a measurement parameter having values that are calibrated against force values associated with forces applied to the probe's tip.
