Fabrication and characterization of flexible ruthenium oxide-loaded polyaniline/poly(vinyl alcohol) nanofibers by Chamakh, M.

“…Impedance spectroscopy for the samples with capacitor structure was conducted as function of RuO2 concentration and temperature. The tests revealed the decrease of electrical resistivity and activation energy with increasing RuO2 concentration for the as-prepared samples, while the annealed samples showed lower activation energy values of ~0.1 eV with increasing the concentration of RuO2. …”

Gaining or losing team ball possession: The dynamics of momentum perception and strategic choice in football coaches by Briki, Walid

“…Nonetheless, both variables displayed asymmetrical effects, in the sense that: (1) the strength of positive PM appeared to be easier to decrease than to increase; and (2) the greater the positive PM (or the negative PM), the lesser (or the greater) the coaches' tendency to make a change in the organization of their teams. …”

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

“…Diaz found that the performance of the bivariate model deteriorates when between-study heterogeneity increases and the number of studies decrease.5 Our simulation studies found similar results—with moderate levels of heterogeneity (tau2 = 1), the coverage probabilities of Se, Sp, and the diagnostic odds ratio (DOR) with the bivariate model dropped below the nominal level.6 Diagnostic accuracy studies usually favor sensitivity over specificity, or vice versa leading to diagnostic 2 × 2 tables with one or more of the cells with low frequency or zero counts. …”
