Model-free Analysis of Scattering and Imaging Data with Escort-Weighted Shannon Entropy and Divergence Matrices
Jared Coles, Arthur R. C. McCray, Yue Li +9
We demonstrate a model-free data analysis framework that leverages escort-weighted Shannon Entropy and several divergence matrices to detect phase transitions in scattering and ima…
A Gaussian Parameterization for Direct Atomic Structure Identification in Electron Tomography
Nalini M. Singh, Tiffany Chien, Arthur R. C. McCray +2
Atomic electron tomography (AET) enables the determination of 3D atomic structures by acquiring a sequence of 2D tomographic projection measurements of a particle and then computat…
Missing Wedge Inpainting and Joint Alignment in Electron Tomography through Implicit Neural Representations
Cedric Lim, Corneel Casert, Arthur R. C. McCray +4
Electron tomography is a powerful tool for understanding the morphology of materials in three dimensions, but conventional reconstruction algorithms typically suffer from missing-w…
Deep generative priors for robust and efficient electron ptychography
Arthur R. C. McCray, Stephanie M. Ribet, Georgios Varnavides +1
Electron ptychography enables dose-efficient atomic-resolution imaging, but conventional reconstruction algorithms suffer from noise sensitivity, slow convergence, and extensive ma…
