Background: Many studies have been conducted in urban areas in other Indian states to study the profile of causes of visual impairment; however, such a study was lacking in Goa.Methods: The study was conducted between January to March 2018, after Institutional ethical committee approval.The study population included 200 patients residing in househo
Abstract Background In survey studies on health-state valuations, ordinal ranking exercises often are used as precursors to other elicitation methods such as the time trade-off (TTO) or standard gamble, but the ranking data have not been used in deriving cardinal valuations.This study reconsiders the role of ordinal ranks in valuing health and intr
Abstract Quantum theory does not prevent entanglement from being created and observed in macroscopic physical banana ointment systems, in reality however, the accessible scale of entanglement is still very limited due to decoherence effects.Recently, entanglement has been observed among atoms from thousands to millions levels in extremely low-tempe
In the perspective of an upcoming seasonally ice-free Arctic, understanding the dynamics of sea ice in the changing climate is a major challenge in oceanography and climatology.In particular, the new generation of sea ice models will require fine parameterization of sea ice thickness and rheology.With the rapidly evolving state of sea ice, achievin
A novel method to determine the dispersion of the quadratic electro-optic effect in nonlinear optical materials by using a silicon-on-insulator microring resonator is presented.The microring consists of a silicon slot waveguide enabling large dc electric field strength at low applied voltages.The dispersion of third-order hyperpolarizability of a l
