Density functional theory (DFT) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1H)–one (MPO), as a representative of pyridinone derivatives, at the fullerene (C60) surfaces. Optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (CQ) have been e...

We investigate interchangeability of values in CSPs, based on an approach where a single value in the domain of a variable can be treated as a combination of "sub-values". An algorithm for removing overlapping sub-values is presented. The resulting CSPs take less time to find all solutions and yield a more compactly-representable, but equivalent, solution set. Experimental results show that, es...

Simultaneous reduction of N2O in the presence co-existing oxidants, especially NO, from industrial plants, is a challenging task.

In recent years, sub−band speech recognition has been found useful in robust speech recognition, especially for speech signals contaminated by band−limited noise. In sub−band speech recognition, full band speech is divided into several frequency sub−bands and then sub−band feature vectors or their generated likelihoods by corresponding sub−band recognizers are combined to give the result of rec...

the changing demands on the health sectors in low- and middle-income countries especially sub-saharan african countries continue to challenge efforts to address critical shortages of the health workforce. addressing these challenges have led to the evolution of “non-physician clinicians” (npcs), that assume some physician roles and thus mitigate the continuing shortage of doctors in these count...
