  text: Efficient utilization of large-scale biobank data is crucial for inferring
    the genetic basis of disease and predicting health outcomes from the DNA. Yet
    we lack efficient, accurate methods that scale to data where electronic health
    records are linked to whole genome sequence information. To address this issue,
    our paper develops a new algorithmic paradigm based on Approximate Message Passing
    (AMP), which is specifically tailored for genomic prediction and association testing.
    Our method yields comparable out-of-sample prediction accuracy to the state of
    the art on UK Biobank traits, whilst dramatically improving computational complexity,
    with a 8x-speed up in the run time. In addition, AMP theory provides a joint association
    testing framework, which outperforms the currently used REGENIE method, in roughly
    a third of the compute time. This first, truly large-scale application of the
    AMP framework lays the foundations for a far wider range of statistical analyses
    for hundreds of millions of variables measured on millions of people.

  text: This paper proposes a novel cooperative approach for two-hop amplify-and-forward
    (A&F) relaying that exploits both the signal forwarded by the relay and the one
    directly transmitted by the source in impulse-radio ultra-wideband (IR-UWB) systems.
    Specifically, we focus on a non-coherent setup employing a double-differential
    encoding scheme at the source node and a single differential demodulation at the
    relay and destination. The log-likelihood ratio based decision rule is derived
    at the destination node. A semi-analytical power allocation strategy is presented
    by evaluating a closed-form expression for the effective signal to noise ratio
    (SNR) at the destination, which is maximized by exhaustive search. Numerical simulations
    show that the proposed system outperforms both the direct transmission with single
    differential encoding and the non-cooperative multi-hop approach in different
    scenarios.
