Abstract: Described herein are cannulas having a stepped exterior. Also described are methods of making and using these cannulas, for example to deliver one or more materials to the central nervous system of an animal.

Abstract: The present invention provides pluripotent stem cell like (PSCL) cells or clones, a culture medium therefore, and a supernatant thereof, and methods of making and using the same.

Abstract: An optoelectronic device (e.g., LED) comprising one or more conformal surface electrical contacts conforming to surfaces of the device; and a high refractive index glass partially or totally encapsulating the device and the conformal surface electrical contacts, wherein traditional wire bonds and/or bond pads are not used and the glass is a primary encapsulant for the device.

Abstract: A gas sensing device (nanosensor) includes a substrate with at least a pair of conductive electrodes spaced apart by a gap, and an electrochemically functionalized semiconductive nanomaterial bridging the gap between the electrodes to form a nanostructure network. The nanomaterial may be single-walled carbon nanotubes (SWNTs) functionalized by the deposition of nanoparticles selected from the group consisting of an elemental metal (e.g., gold or palladium), a doped polymer (e.g., camphor-sulfonic acid doped polyaniline), and a metal oxide (e.g. tin oxide). Depending on the nanoparticles employed in the functionalization, the nanosensor may be used to detect a selected gas, such as hydrogen. mercury vapor, hydrogen sulfide, nitrogen dioxide, methane, water vapor, and/or ammonia, in a gaseous environment.

Abstract: A method includes inspecting a packet stream sent from a set-top box device via a network. The packet stream includes video content that is divided into a plurality of subsections. The method includes generating a plurality of signatures by applying a wavelet transform to each of the plurality of subsections, and determining a match between the video content and protected video content based at least in part on a comparison of the plurality of signatures to one or more stored signatures generated based on the protected video content.

Abstract: A plasma lens for enhancing the quality and rate of sputter deposition onto a substrate is described herein. The plasma lens serves to focus positively charged ions onto the substrate while deflecting negatively charged ions, while at the same time due to the line of sight positioning of the lens, allowing for free passage of neutrals from the target to the substrate. The lens itself is formed of a wound coil of multiple turns, inside of which are deposed spaced lens electrodes which are electrically paired to impress an E field overtop the B field generated by the coil, the potential applied to the electrodes increasing from end to end towards the center of the lens, where the applied voltage is set to a high potential at the center electrodes as to produce a potential minimum on the axis of the lens.

Abstract: There are provided, inter alia, acyclic nucleoside phosphonate compounds having reduced toxicity and enhanced antiviral activity, and pharmaceutically accepted salts and solvates thereof. There are also provided methods of using the disclosed compounds for inhibiting viral RNA-dependent RNA polymerase, inhibiting viral reverse transcriptase, inhibiting replication of virus, including hepatitis C virus or a human retrovirus, and treating a subject infected with a virus, including hepatitis C virus or a human retrovirus.

Abstract: The disclosure provides zeolitic frameworks for gas separation, gas storage, catalysis and sensors. More particularly the disclosure provides zeolitic frameworks (ZIFs). The ZIF of the disclosure comprises any number of transition metals or a homogenous transition metal composition.

Abstract: The present invention discloses a plurality of interdigitated pixels arranged in an array, having a very low series-resistances with improved current spreading and improved heat-sinking Each pixel is a square with sides of dimension 1. The series resistance is minimized by increasing the perimeter of an active region for the pixels. The series resistance is also minimized by shrinking the space between a mesa and n-contact for each pixel.
