  • Patent number: 10260143
    Abstract: A directed vapor deposition (DVD) method and system for applying at least one bond coating on at least one substrate for thermal barrier coating systems. To overcome the limitations incurred by conventional methods, the DVD system uses an electron beam directed vapor deposition (DVD) technique to evaporate and deposit compositionally and morphologically controlled bond coats at high rate. The present DVD system uses the combination of an electron beam and a combined inert gas/reactive gas carrier jet of controlled composition to create engineering films. In this system, the vaporized material can be entrained in the carrier gas jet and deposited onto the substrate at a high rate and with high materials utilization efficiency. The velocity and flux of the gas atoms entering the chamber, the nozzle parameters, and the operating chamber pressure can all be significantly varied, facilitating wide processing condition variation and allowing for improved control over the properties of the deposited layer.

  • Patent number: 10256906
    Abstract: Visible-light communication (VLC) is an optical wireless communication technique that uses light emitting diodes (LEDs) or other optical sources to transmit information to a user equipment (UE) device. An optically-based location determination approach, such as using VLC infrastructure, can meet a desire for location-based services where use of VLC can provide a solution to an indoor localization or navigation problem. A fingerprinting approach can include use of an optical received signal strength (RSS) or other information (e.g., an image of a scene) to generate a spatial fingerprint map of an area. A later-received RSS on the UE device and the prior-generated fingerprint map representative of RSS can be received, and a fingerprint map and RSS observations can be provided as inputs to a Bayesian filter, such as an Extended Kalman Filter (EKF) or a Particle Filter, to provide an estimated position for the UE device.

  • Publication number: 20190070356
    Abstract: Provided is a method and system for delivering a diagnostic agent to a site in the brain of a subject for imaging at least a portion of the brain site on a medical imaging system. The method and system includes a catheter device with associated lumens having diagnostic agent ports for delivering the diagnostic agent (e.g., infusate) through the lumens and advancing the diagnostic agent so as to exit out from the lumens to at least a portion of the brain site and while sealing a portion of the brain site thereby preventing the exited diagnostic agent from travelling proximally beyond the sealing location, and at the same time imaging at least a portion of the brain site during at least a portion of the sealing duration so that the brain site can be visualized on a medical imaging system. The diagnostic agent (infusate) is able to highlight borders and internal patterns of the deep structures of the brain thereby enabling direct targeting.

  • Publication number: 20190060317
    Abstract: Ritanserin is shown to be an inhibitor of diacylglycerol kinase alpha (DGK?) and to be cytotoxic to glioblastoma and melanoma cells. Ritanserin treatment also provides chemo- and radiosensitization in cancer cells, prolonged survival in mouse models of glioblastoma, decreased melanoma tumor burden in mice, and shows synergistic cytotoxic effects with temozolomide and chloroquine, both singly and in combination. DGK? inhibition with ritanserin shows particular toxicity to the treatment-resistant mesenchymal subtype in glioblastoma and other cancers.

  • Patent number: 10196453
    Abstract: Clostridium difficile is the most common hospital acquired pathogen in the United States, and infection is in many cases fatal. Toxins A and B are its major virulence factors, but increasingly a third toxin may be present, known as C. difficile transferase (CDT). An ADP-ribosyltransferase that causes actin cytoskeletal disruption, CDT is typically produced by the major, hypervirulent strains and has been associated with more severe disease. It is disclosed herein that CDT enhances the virulence of two PCR-ribotype 027 strains in mice. The toxin induces pathogenic host inflammation via a novel Toll-like Receptor 2 (TLR2) dependent pathway, resulting in the suppression of a protective host eosinophilic response. Finally, it is disclosed that restoration of TLR2 deficient eosinophils is sufficient for protection from a strain producing CDT. These findings offer an explanation for the enhanced virulence of CDT-expressing C.

  • Patent number: 10193927
    Abstract: Systems and methods for relocating executable instructions to arbitrary locations are described, in which the relocation of the instructions may be arbitrary or random, and may operate on groups of instructions or individual instructions. Such relocation may be achieved through hardware or software, and may use a virtual machine, software dynamic translators, interpreters, or emulators. Instruction relocation may use or produce a specification governing how to relocate the desired instructions. Randomizing the location of instructions provides defenses against a variety of security attacks. Such systems and methods may provide many advantages over other instruction relocation techniques, such as low runtime overhead, no required user interaction, applicability post-deployment, and the ability to operate on arbitrary executable programs.
