Correlation between ionospheric scintillation effects and GNSS positioning over Brazil during the last solar maximum (2012–2014)
(2019-01-01)
GNSS (Global Navigation Satellite Systems) can provide high accuracy positioning at low cost. But, depending on the sources of error, e.g. the atmospheric effects, this accuracy can be degraded. The ionosphere is one of ...
Potential ligand-binding residues in rat olfactory receptors identified by correlated mutation analysis
(Harwood Acad Publ Gmbh, 1995-01-01)
A family of G-protein-coupled receptors is believed to mediate the recognition of odor molecules. In order to identify potential ligand-binding residues, we have applied correlated mutation analysis to receptor sequences ...
Compositional uniqueness of diatoms and insects in subtropical streams is weakly correlated with riffle position and environmental uniqueness
(2019-10-01)
Some local communities contribute more to beta diversity than others, which has been known as compositional uniqueness or local contribution to beta diversity. Compositional uniqueness should correlate positively with ...
Cephalometric evaluation of the airway space and hyoid bone in children with normal and atypical deglutition: correlation study
(Associacao Paulista MedicinaSao PauloBrasil, 2012)
Association of student position in classroom and school performance
(2010)
We analyzed whether the position of students in classroom is correlated with academic performance, and which factors might be involved. The sample consisted of 16 classrooms in a school year bimester, each one with around ...

On the positive correlation between income inequality and unemployment
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2004-08-01)
Several empirical studies in the literature have documented the existence of a positive correlation between income inequalitiy and unemployment. I provide a theoretical framework under which this correlation can be better ...
Cephalometric Evaluation of the Airway Space and Hyoid Bone in Children with Atypical Deglutition: Correlations Study
(Soc Chilena AnatomiaTemucoChile, 2012)
Evaluation of the gnss positioning performance under influence of the ionospheric scintillation
(2020-01-01)
The ionosphere may not only degrade the accuracy of the GNSS positioning but also reduce its availability because there is a high dependence between signal losses and ionospheric irregularities. Irregularities in the Earth’s ...
