    Overconfident results with the bivariate random effects model for meta-analysis of diagnostic accuracy studies حسب Furuya-Kanamori, Luis

    منشور في 2022
    "…In 2001, Rutter and Gatsonis proposed the hierarchical summary receiver operating characteristic (HSROC) model,1 and in 2004 Macaskill described an empirical Bayes approach.2 Soon after, in 2005, Reitsma et al. proposed the bivariate random effects model,3 which has been widely adopted and is the most commonly used method for diagnostic meta-analysis.4 However, as pointed out by Diaz,5 the statistical performance of the bivariate model has not been scrutinized. …"

    Molecular dynamics of CH4/CO2 on calcite for enhancing gas recovery حسب Carchini, Giuliano

    منشور في 2022
    "…These results highlight how the CO2 geometry of adsorption is well defined and characterized by strong interaction, while methane adsorption is quite loose and depicts a very dynamic picture. Focusing on the effect of pressure, RDF peaks intensities increase, although this effect is limited to the 1-5 MPa range. …"
