Abstract: A novel anti-microbial coating and uses thereof on medical devices are presented. The novel coating is comprised of a layer of boron carbon nitride (BCN) coated onto a medical device such as a catheter. The BCN coating was found to inhibit bacterial growth by at least 80% and reduce biofilm formation by at least 60% on the treated surface of the catheter. This coating can be used to reduce or prevent central line associated bloodstream infections (CLABSI) in patients as well as inhibit bacterial growth and biofilm formation on a variety of medical devices or polymeric surfaces.

Abstract: A quantum cascade laser (QCL) may include multiple branch waveguide regions having one or more laser cores providing optical gain at one or more output wavelengths, a stem waveguide region, and multiple couplers arranged to couple light from the plurality of branch waveguide regions to the stem waveguide region. Each of the couplers may include two or more curved waveguide regions having a continuously-varying radius of curvature providing that a fundamental transverse mode at the output wavelengths is dominant, and a coupler to combine light from the two or more curved waveguides and maintain dominance of the fundamental transverse mode at the output wavelengths. The fundamental transverse mode at the output wavelengths may be dominant in output light from the stem waveguide.

Abstract: A glass fiber-based structural composite offers an alternative or supplement to carbon fibers in areas such as battery storage. Through electroless deposition of conductive materials like copper and nickel, the glass fiber surface is made conducting and functions as a good current collector. By using anode and cathode materials like manganese (II, III) oxide and Zinc, cathode and anode mats on the copper- and nickel-coated glass fibers are created via hydrothermal and electro-deposition methods. In one example application, the anode and cathode mats are in an alternate square patterned arrangement using copper and nickel-coated glass fiber as a current collector. The device, with a capacity of >300 mAh/g at 0.1 A/g is assembled using an alternate system of epoxy and electrolyte. Uncoated pristine glass fiber ladened and patterned with electrolyte are used as a separator. Uncoated pristine glass fiber ladened with epoxy can be used as an insulator between two devices.

Abstract: An active sparse labeling system that provides high performance and low annotation costs by performing partial instance annotation (i.e., sparse labeling) by frame level selection to annotate the most informative frames, thereby improving action detection task efficiencies. The active sparse labeling system utilizes a frame level cost estimation to determine the utility of each frame in a video based on the frame's impact on action detection. The system includes an adaptive proximity-aware uncertainty model, which is an uncertainty-based frame scoring mechanism. The adaptive proximity-aware uncertainty model estimates a frame's utility using the uncertainty of detections of the frame's proximity to existing annotations, thereby determining a diverse set of frames in a video which are effective for learning the task of dense video understanding (such as action detection). In addition, the active sparse labeling system includes a loss formulation training model (max-Gaussian weighted loss) that uses weighted pseudo-labeling.

Abstract: A quantum key distribution system may include a transceiver including a state randomizer to impart a random state transformation to one or more qubits of a generated faint pulse and a quantum bit encoder to reflect the faint pulse back to the transceiver with one or more encoded bits. The transceiver may receive a return pulse through the communication channel, where the state randomizer reverses the random state transformation. The transceiver may include a set of two detectors to measure the return pulse at time-gated timeslots associated with possible paths of the return pulse. Reception of the faint pulse from the quantum bit encoder as the return pulse triggers a detector in one or more known time-gated timeslots determined based on the random state transformation, while reception of a faked-state pulse results in a non-zero probability of triggering of a detector in a different time-gated timeslot.
