Second order advantage of excitation-emission fluorescence matrix was applied for the simultaneous determination of ibuprofen and caffeine. The proposed method is based on the measurement of the native fluorescence and recording emission spectra of ibuprofen and caffeine in different excitation wavelengths. The mixture of these compounds was resolved by multivariate curve resolution coupled wit...

Previous research with the visual lexical decision task demonstrated that polysemous words (multiple related senses) have a processing advantage when compared to unambiguous words, whereas homonymous unrelated meanings) disadvantage. Although same pattern of results was observed in Serbian, two effects were investigated separate studies. The aim this study test whether can be replicated both ty...

In this article, ambiguity and synonymy effects were examined in lexical decision, naming, and semantic categorization tasks. Whereas the typical ambiguity advantage was observed in lexical decision and naming, an ambiguity disadvantage was observed in semantic categorization. In addition, a synonymy effect (slower latencies for words with many synonyms than for words with few synonyms) was obs...

Bilingual individuals make up a growing part of the United States population. Regardless of controversy on the existence of bilingual advantage vs. disadvantage, the children and families who make up the bilingual patient cohort require special considerations when providing care. Understanding the medical and academic needs of this patient cohort requires an understanding of current available r...

Although neighborhood stressors have a negative impact on youth, and social support can play a protective role, it is unclear what types and sources of social support may contribute to positive outcomes among at-risk youth. We examined the influences of neighborhood disadvantage and social support on global self-worth among low-income, urban African American youth, both concurrently and longitu...

Underdetermined direction-of-arrival (DOA) estimation for quasi-stationary signals impinging on a uniform circular array (UCA) with M sensors is addressed in this paper. We apply the Khatri–Rao (KR) approach to the UCA and obtain a new signal model which is capable of providing OðMÞ sensors. Meanwhile, the virtual steering matrix can be decomposed into a product of characteristic matrix dependi...
