Overconfident results with the bivariate random effects model for meta-analysis of diagnostic accuracy studies
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. …”

Design and analysis of PV fed high-voltage gain DC-DC converter using PI and NN controllers
Published 2022“…When the converter switch comes under active state two capacitors are discharged in series, similarly when the converter switch under inactive state those two capacitors are charged in parallel through the coupled inductor (CI) energy so, to get a high voltage at the converter output side. To reuse the leakage-inductor (LI) energy of the CI with the help of a passive clamp circuit for reducing the voltage stress across the switch, similarly switch has less resistance so conduction losses also decreased. …”
