Designing new single-phase white phosphors for solid-state lighting is a challenging trial–error process as it requires to navigate in multidimensional space (composition of the host matrix/dopants, experimental conditions, etc.). Thus, no phosphor has ever been reported exhibit both high color rendering index (CRI - degree which objects appear natural under illumination) and tunable correlated...

the present study was carried out for evaluation of calcoflour white staining (cws) as a rapid method for detection of pneumocystis carinii in respiratory specimens of rats as an animal model for human infection. a total of 35 spraque – dawley rats were divided into two groups. group1 (20 rats) received increasing doses of dexamethasone subcutaneously, and group 2(15 rats)as control group that ...

statement of problem: fixed orthodontic appliances can interfere with removing bacterial plaques from dental surfaces which can ultimately lead to white spot formation. purpose: the aim of this study was to evaluate the quantity of white spots and areas of decalcification following fixed orthodontic treatment. materials and methods: a total of 100 patients undergoing or scheduled for fixed orth...

How urbanization shapes population genomic diversity and evolution of urban wildlife is largely unexplored. We investigated the impact of urbanization on white-footed mice,Peromyscus leucopus,in the New York City (NYC) metropolitan area using coalescent-based simulations to infer demographic history from the site-frequency spectrum. We assigned individuals to evolutionary clusters and then infe...

In our previous paper, we investigated the effects of image noise on the perception of image sharpness using white noise, and oneand two-dimensional (1D and 2D, respectively) single-frequency sinusoidal patterns as stimuli. Our results showed that with high-frequency stimuli, sharpness decreased as noise level increased; whereas, with low-frequency stimuli, sharpness reached a maximum value at ...
