The presence of foam influences the accuracy of satellite-derived water-leaving radiance. A model has been developed to estimate the augmented reflectance ratio (A(λ, U)) due to differences in the fraction of whitecap coverage (w) on the ocean surface. A(λ, U) can be calculated from the product of w and ρ(λ, U), where ρ(λ, U) is the augmented ratio of the(More)
BACKGROUND AND PURPOSE The quality of after-hour emergency care of patients with acute ischemic stroke is debatable. We therefore, sought to analyze the performance measures, quality of care and clinical outcomes in these patients admitted during off-hours. METHODS Our study included 4493 patients from a selected cohort of patients admitted to the(More)
