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

    Published 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. …”

    Prospects Of Amino Acids And Ionic Liquids As Natural Gas Hydrate Inhibitors For Offshore Flow Assurance by Qureshi, M. Fahed Aziz

    Published 2018
    “…The inhibitors tend to show better hydrate inhibition effect at low pressures (40 bars) and their inhibition effect decreases as the pressure rises. At the same concentration (10 wt%), the ammonium-based ionic liquid [EA][Of] provided the inhibition effect similar to MEG and at the higher concentration (20 wt%) the amino acid glycine provided better hydrate inhibition effect than the MEG. …”
