Material Identification From Radiographs Without Energy Resolution
Michael T. McCann, Elena Guardincerri, Samuel M. Gonzales +3
We propose a method for performing material identification from radiographs without energy-resolved measurements. Material identification has a wide variety of applications, includ…
High-Precision Inversion of Dynamic Radiography Using Hydrodynamic Features
Maliha Hossain, Balasubramanya T. Nadiga, Oleg Korobkin +7
Radiography is often used to probe complex, evolving density fields in dynamic systems and in so doing gain insight into the underlying physics. This technique has been used in num…
Local Models for Scatter Estimation and Descattering in Polyenergetic X-Ray Tomography
Michael T. McCann, Marc L. Klasky, Jennifer L. Schei +1
We propose a new modeling approach for scatter estimation and descattering in polyenergetic X-ray computed tomography (CT) based on fitting models to local neighborhoods of a train…
A quantum mechanical model of the upper bounds of the cascading contribution to the second hyperpolarizability
Nathan J. Dawson, Benjamin R. Anderson, Jennifer L. Schei +1
Microscopic cascading of second-order nonlinearities between two molecules has been proposed to yield an enhanced third-order molecular nonlinear-optical response. In this contribu…
A classical model of the upper bounds of the cascading contribution to the second hyperpolarizability
Nathan J. Dawson, Benjamin R. Anderson, Jennifer L. Schei +1
We investigate whether microscopic cascading of second-order nonlinearities of two molecules in the side-by-side configuration can lead to a third-order molecular nonlinear-optical…
