Abstract: A system for performing functional brain mapping includes a memory configured to store first data from a magnetic resonance imaging (MRI) system and second data from electrodes. The system also includes a processor operatively coupled to the memory and configured to identify first edges in a brain network based on the first data from the MRI and second edges in the brain network based on the second data from the electrodes. The processor is configured to determine, based on the first edges and the second edges, connectivity metrics for the brain network. The processor is also configured to generate, based at least in part on the connectivity metrics, a decoder that differentiates between critical nodes and non-critical nodes in the brain network.

Abstract: A communications network (e.g. fibre to the home (FTTH) or wireless) comprises a head end, to which outstations are coupled via a shared point-to-multipoint medium. The head end is arranged to transmit downstream to the outstations a sequence of frames comprising data frames and command frames. The command frames marshal control of upstream transmissions from the outstations. A first downstream command frame directed to a specific outstation indicates the beginning of a timeslot, and also indicates the timeslot duration (including an indefinite duration). Where the duration is indefinite, a second command frame directed to at least the same outstation indicates the end of the allotted time slot. Further methods are provided to optimise timeslot allocation, and to support addition and removal of outstations on the network.

Abstract: A digital subscriber loop modem arrangement is arranged to respond to a fault condition so as to provide at least a voice lifeline service over DSL service on a digital subscriber line in which data and voice traffic are transported on a plurality of carriers. On detection of a power loss at the subscriber end of the line, the number of carriers is reduced so as to maintaining transmission only of those carriers transporting the voice traffic. This reduces the power demand which can now be met from the remote end of the line. A method of operating a digital subscriber loop modem arrangement under a fault condition so as to provide at least a voice over DSL service on a digital subscriber line in which data and voice traffic are transported on a plurality of carriers, the method comprising the steps of: replacing the data with random data, disabling those data carriers on which the random data is transported, and maintaining transmission of those carriers transporting the voice traffic.

Abstract: A method of and apparatus for capacity determination in a telecommunications system, in the presence of Gaussian and non-Gaussian noise. The ratio of Gaussian to non-Gaussian noise is determined utilising a statistical metric. Preferably the metric is Kurtosis or the 3rd Cumulant of the Probability Density of the signal at each frequency. The determination of the ratio of Gaussian to non-Gaussian noise enables a more accurate determination of Noise, which in turn allows greater utilisation of actual available capacity in the system.

Abstract: A modem (34, 40) at a customer premises (14, 38) and a switch at an exchange (12, 50) are modified to allow a data session (102, 202) supported on a dedicated wireline communication resource (16) to be optionally terminated (110), but preferably suspended (114, 218), upon detection of a subsequently placed voice call (104, 204) on the dedicated wireline communication resource (16). Before termination of a data session, a user either selects a termination option or is provided with an in-call option to terminate the data session, with the voice call then switched (122) to the dedicated wireline communication resource (16). The data session is therefore cleared down rather than lost through connection corruption. Alternatively, the modem (34, 40) and the exchange (50) interact to silence modem transmissions therebetween, whilst retaining a data connection (20) between the exchange (12, 50) and an end-point data service provider (ISP, 18).

Abstract: Known communications systems for providing Near Video On-Demand services require a large quantity of bandwidth in order to transfer a number of time-staggered versions of an original data stream to a set-top decoders. In order to reduce bandwidth requirements, the present invention provides a communications system (100) for providing data streaming services to a plurality of client terminator units (122) by providing a multicast server (108) capable of delivering a number of time-staggered versions of an original data stream to the plurality of client terminator units (122). (Consequently, the present invention advantageously obviates a need for a relatively large bandwidth to be provided for communications between a content providing server (102) and the multicast server (108).

Abstract: A shared-medium communications access network (e.g. fiber to the home (FTTH) or wireless) comprises a head end, to which outstations are coupled via an optical fiber medium incorporating a star coupler or splitter. The head end is arranged to transmit downstream to the outstations a sequence of frames comprising data frames and command frames. The command frames comprise first and second frames and provide marshalling control of upstream transmissions from the outstations. The first command frame incorporates a global command to all outstations to pause upstream transmission for a pre-set time period. The second command frame is transmitted within the pre-set period and incorporates a further pause command having an associated zero time period and addressed to a selected outstation overriding said global command thus allowing that one selected outstation to transmit to the head end.

Abstract: A method, apparatus, and software for providing lifeline service during power failure affecting Customer Premises Equipment (CPE) in a Digital Subscriber Loop (DSL) arranged to carry voice traffic in band rather than on a separate analogue POTS band. The arrangement provides a reduced service, capable of supporting at least one voice call, to operate during such power failure and, where a single call is in progress during power failure, that call may be maintained during the transition from DSL to analogue POTS lifeline service. Where a call is in progress upon power restoration, the lifeline POTS service may be maintained until completion of the call so as not to interrupt a potential lifeline call.

Abstract: An orthogonal frequency division multiplex (OFDM) transmission system, e.g. for tranmitting data traffic over a telephone subscriber twisted pair loop, includes a transmitter for generating sets of time division samples in respective channels corresponding to an input data sequence comprising a series of bits, and a receiver coupled to the transmitter via the transmission path. The receiver incorporates a time variant digital filter having a plurality of elements one for each said channel, and Fourier transform means for recovering the data stream from the outputs of said filter elements. The time variant digital filter comprises a set of wavelet filters one for each transmission channel and whose tap weights are determined so as to provide specific interference rejection.

Abstract: An improved plating media incorporates TERGITOL.RTM.4, an alkyl sodium sulfate biological detergent, in a Xylose-lysine agar base. The plating media may also include peptone and sulfapyridine to further inhibit Citrobacter growth. The media is highly preferential for Salmonella, giving a greater number of Salmonella positives, and reduced competitive organisms. When incorporated with drag swab methodology employing skim milk or evaporated milk as a holding media, which may advantageously include novobiocin to suppress unwanted bacterial growth, coupled with a tetrathionate-culturing broth or other selective enrichment broth, the plating media completes a highly sensitive assay for the detection of Salmonella, particularly keyed for poultry and livestock handling structures, and for veterinary and human clinical laboratory applications.
