  9. Cross talk between the glucocorticoid receptor and the progesterone receptor in modulation of progestin responses and HIV-1 infection by Bick, Alexis J

    Published 2018
    “…Taken together, MPA increases HIV-1 infection in a manner different from that of luteal phase hormones, most likely involving increased CD4+ T cell frequency (CD4+/CD8+ ratio), activation and increased expression of CCR5 on CD4+ T cells, and requiring the GR. …”

  16. Low-Complexity Algorithms for Channel Estimation in Optimised Pilot-Assisted Wireless OFDM Systems by Golovins, Eugene

    Published 2014
    “…The common estimator structure represents a cascade of successive small-dimension filtering modules. The number of modules, as well as their order inside the cascade, is determined by the class of the estimator (one or two-dimensional) and availability of the channel statistics (correlation and signal-to-noise power ratio). …”
