    Abstract: A photonic processor computing engine device can include a photonic integrated circuit including an optical phased array having a plurality of radiating pixels that radiate optical signal beams. Each of the radiating pixels can include an optical antenna and an optical phase modulator. The engine can include an electronic control circuit positioned to receive the optical signal beams transmitted from the radiating pixels. The computing engine can further include an electronic feedback circuit in electrical communication with the focal plane array and the electronic control circuit to process a measured intensity of the optical signal beams received by the focal plane array from the optical phased array and provide a feedback signal to the electronic control circuit based on the measured intensity for recalibrating the optical phase modulators of the plurality of radiating pixels to control the phase of the optical signal beams emitted by the plurality of radiating pixels.

    Abstract: A machine accesses a query in a first natural language. The machine identifies an event corresponding to the query. The machine computes, using a cross-lingual information retrieval module, a ranked list of documents in a second natural language that are related to the event. At least a portion of documents in the ranked list are selected from a collection of documents in the second natural language that are not annotated with events. The cross-lingual information retrieval module is trained using a dataset comprising annotated documents in the first natural language and translations of the annotated documents into the second natural language. Each annotated document is annotated with one or more events. The machine provides an output representing at least a portion of the ranked list of documents in the second natural language. The second natural language is different from the first natural language.

    Abstract: Systems and method herein describe embedding graphs into a semantic multidimensional space by receiving a dataset, constructing a Markov chain from the dataset, the Markov chain comprising a plurality of nodes selecting a basis node and a target node from the plurality of nodes, determining a distance from the target node to the basis node, storing the distance between the target node and the basis node in a vector, analyzing the vector, and determining a semantic characteristic of the target node based on the analysis of the vector.

    Abstract: A tunable oscillator including a Josephson junction. In some embodiments, the tunable oscillator includes a first superconducting terminal, a second superconducting terminal, a graphene channel including a portion of a graphene sheet, and a conductive gate. The first superconducting terminal, the second superconducting terminal, and the graphene channel together may form a Josephson junction having an oscillation frequency, and the conductive gate may be configured, upon application of a voltage across the conductive gate and the graphene channel, to modify the oscillation frequency.

    Abstract: An acoustic vector sensor and a method of detecting an acoustic vector are described. An object suspended in the fluid medium by a non-contact support structure. The object and the non-contact support structure are configured so that the object moves in response to any disturbance of the fluid by an acoustic wave; The non-contact support structure of the object comprises a plurality of solenoids that each produce a magnetic field in a fluid medium. A measurement measures movement of the object. A processing device determines an acoustic intensity vector of the acoustic wave based on the measured movement of the object.
