Surface PM2.5 concentrations are required for exposure assessment studies. Remotely sensed Aerosol Optical Depth (AOD) has been used to derive PM2.5 where ground data is unavailable. However, two key challenges in estimating surface PM2.5 from AOD using statistical models are (i) Satellite data gaps, and (ii) spatio-temporal variability in…[Read more]

e result, while functional correction means simpler operation.The pulmonary valve (PV) has historically been ignored by imaging studies. Disorders of the PV encountered in adult cardiac patients are increasingly encountered due to advanced care of patients with congenital heart disease and associated PV diseases. Despite advances in PV imaging,…[Read more]
