The dual approach to non-negative super-resolution: perturbation analysis and data fidelity
Stéphane Chrétien, Andrew Thompson, Bogdan Toader
We study the problem of super-resolution, where we recover the locations and weights of non-negative point sources from (potentially noisy) samples of their convolution with a Gaus…

Efficient high-resolution refinement in cryo-EM with stochastic gradient descent
Bogdan Toader, Marcus A. Brubaker, Roy R. Lederman
Electron cryomicroscopy (cryo-EM) is an imaging technique widely used in structural biology to determine the three-dimensional structure of biological molecules from noisy two-dime…
