The role of type II FB (I):Tl+ defect in laser light generation and color image formation at the low coordination surface sites of AgBr: Ab initio calculations حسب Shalabi, A.S.

"…All relaxed excited states of the defect containing surfaces were deep below the lower edges of the conduction bands of the ground-state defect-free surfaces indicating that type II FB(I):Tl+ is suitable laser defect. The probability of orientational destruction of the two centers, attributed to the assumed saddle point ion configurations along the 〈1 1 0〉 axis, was found to decrease as the coordination number of the surface ions decreases. …"

Advanced Hard Ctings: Towards A Whole New World حسب Santecchia, Eleonora

"…The main problem with steel, is that it exhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K. Thus, the majority of modern tools are nowadays coated with hard coatings, in order to: (i) increase the hardness, (ii) decrease the coefficient of friction, and (iii) protect the tools against oxidation. …"

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