    摘要： A communications system is provided having SONET communications channels extending between first and second locations. The channels include pairs of forward and reverse channels for carrying traffic in normal operation between first and second locations and a protection channel for carrying traffic of one channel in the event of a fault. Each pair of forward and reverse channels is provided on a shelf at each location, the shelves having the same relative position at both locations and the protection channel is provided on a protection shelf. The protection channel includes, between the first and second locations, a forward optical link and a reverse optical link and at each of the first and second locations, a single protection loop, coupling the forward and reverse optical links, that forms the protection channel. The protection loop is used to provide, at each location, a local virtual protection loop for indicating the protection requirements and status of the respective location, and a remote virtual protection loop for indicating the protection requirements and status of the location remote from the respective location. The local protection loop is provided by inserting K1 and K2 bytes into E1 slots of STS-1 #25 and #2, respectively. The remote protection loop is provided by inserting K1 and K2 bytes into E1 slots of STS-1 #26 and #3, respectively.

    摘要： A grow plant enclosure to maximize plant density for a given growing area has a perimeter frame, a first pane, and a second pane. The first pane is adjacently connected to the perimeter frame, while the second pane is removably attached to the perimeter frame opposite the first pane to form a hollow enclosure. A plurality of plug holder openings traverses through the first pane, and optionally the second pane, being designed to receive a plurality of plant holders for growing various plant types. A plurality of supply tubes traverse into the perimeter frame through a plurality of supply tube openings and each have a plurality of spray nozzles to deliver nutrient solution to the root zone of the plants retained in the plurality of plant holders. Excess nutrient solution is released through a drain fixture positioned about the bottom of the perimeter frame.

    摘要： Modified forms of naturally occurring bacteriocins, such as the R-type pyocins of Pseudomonas aeruginosa, are disclosed. The bacteriocins are modified at the ends of their tail fibers in a region responsible for binding specificity and affinity to their cognate binding partners, or receptors, such as those on the surface of bacteria. Methods for the use of the modified bacteriocins, such as to bind receptors, including virulence or fitness factors, on the surfaces of bacteria, are also described.

    摘要： An Ethernet mapping enables high speed Ethernet data streams having a data rate of 10 Gb/s to be transported across a synchronous packet switched network fabric having a standard SONET OC-192 line rate of 9.953280 Gbaud. The 10 Gb/s Ethernet data stream is compressed by removing interframe gaps between successive MAC frames to produce a compressed data stream, which is then mapped to a synchronous container. The synchronous container is then launched across the synchronous packet switched network fabric at a standard SONET OC-192 line rate of 9.953280 Gbaud. The synchronous container is preferably provided as a stripped STS-192c frame having only A1 and A2 octets of the Transport Overhead (TOH). The compressed data stream is mapped directly to the synchronous container, starting at the first octet following the A1 and A2 octets, without first being inserted into a conventional STS-192c SPE, so that most of the space normally used for TOH and Path overhead (POH) within a conventional STS-192c frame is freed-up for carrying the compressed data stream. At a receiving interface, the compressed data stream is extracted from received synchronous containers and decompressed, by insertion of interframe gaps between successive MAC frames, to generate a recovered 10 Gb/s Ethernet data stream. The starting bit of each successive MAC frame can be identified by examination of the length field of the immediately previous MAC frame.
