    The Redshift-space Momentum Power Spectrum. III. Measuring the Growth Rate from the SDSSv Survey Using the Auto- and Cross-power Spectrum of the Galaxy Density and Momentum Fields by Fei Qin, Cullan Howlett, David Parkinson

    Published 2024-01-01
    “…The large-scale structure of the Universe and its evolution over time contains an abundance of cosmological information. One way to unlock this is by measuring the density and momentum power spectrum from the positions and peculiar velocities of galaxies and fitting the cosmological parameters from these power spectra. …”

    Performance Analysis of RIS-Aided Hybrid RF-FSO Communications With Index Modulation by Yuna He, Wenchao Qi, Pengfei Shen, Lu Lu

    Published 2025-01-01
    “…Link switching is performed through index modulation, where the selection of the transmission link conveys information bits. We derive exact closed-form expressions for the probability density function (PDF), cumulative distribution function (CDF), and moment-generating function (MGF) of the signal-to-noise ratio (SNR) for RIS-assisted FSO links. …”

    Mt or not Mt: Temporal variation in detection probability in spatial capture-recapture and occupancy models by Sollmann, Rahel

    Published 2024-01-01
    “…I simulated data under different scenarios of temporal and spatio-temporal variation in detection, analyzed data with the data-generating model and an alternative model ignoring temporal variation in detection, and compared estimates between these two models with respect to relative bias, coefficient of variation (CV) and relative root mean squared error (RMSE). SCR model estimates of abundance, the density-covariate coefficient β and the movement-related scale parameter of the detection function σ were robust to ignoring temporal variation in detection, with relative bias, CV and RMSE of the two models generally being within 4% of each other. …”

    INDIRECT METHODS FOR DETERMINING THE MASS OF LIQUEFIED NATURAL GAS IN CRYOGENIC TRANSPORTATION TANKS by I. S. Medvedkov

    Published 2021-04-01
    “…The calculation of the mass of the cryogenic vapor-liquid medium is associated with the determination of the density of the vapor and liquid phases. The densities of media, in turn, depend on their component  composition, pressure, and temperature, which, in general, cannot be  determined reliably without direct measurements. …”
