  • Patent number: 8401020
    Abstract: Requests of resources of uplink flows towards a base station (BS) and/or downlink flows towards end nodes are computed by each requesting node on an end-to-end basis. Each requesting node issues a cumulative request given by summing up the same request for each link separating the node from the BS plus each link separating the BS from the destination node, enabling the centralized node to perform connection based scheduling. The BS in response to all cumulative requests grants uplink and/or downlink resources for each link. The profile of grants is equal to the profile of requests when the amount of resources requested is below the maximum net throughput on MAC layer. When not below the maximum net through-put on MAC layer, the ideal profile of grants is normalized with respect to a ratio between the maximum net throughput on MAC layer and the amount of the overall requested resources.

  • Patent number: 7531714
    Abstract: The present invention concerns non-human transgenic animals as model study for human pathologies, being transgenic for having altered melusin expression. The non-human transgenic animals are to be used as models to study heart pathologies and provide therapies thereof, wherein the heart pathologies are heart failure, and in particular diluted cardiomyopathy.

  • Patent number: 4503533
    Abstract: Disclosed is a local area communication network based upon a broadcast communication system comprising an inbound channel and an outbound channel, a plurality of stations connected to both the inbound and the outbound channels, transmitting on the outbound channel which utilizes an access protocol where the the access protocol used by the stations connected to the bus is a distributed algorithm and is based upon a conflict-free round robin (RR) access scheme. The time required to switch from one active user to the next in a round is minimized (on the order of carrier detection time, and is independent of the end-to-end network propagation delay. This improvement is particularly significant when the channel data rate is so high, or the end-to-end propagation delay is so large, or the packet size is so small as to render the end-to-end propagation delay a significant fraction of, or larger than, the transmission time of a packet.
