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…
Weakly nonlinear analysis of particle-laden Rayleigh-Bénard convection
Thota Srinivas, Gaurav Tomar
We investigate the effect of inertial particles on Rayleigh-Bénard convection using weakly nonlinear stability analysis. In the presence of nonlinear effects, we study the limitin…
Geometry-Aware Diffusion Models for Multiview Scene Inpainting
Ahmad Salimi, Tristan Aumentado-Armstrong, Marcus A. Brubaker +1
In this paper, we focus on 3D scene inpainting, where parts of an input image set, captured from different viewpoints, are masked out. The main challenge lies in generating plausib…
Amortized In-Context Bayesian Posterior Estimation
Sarthak Mittal, Niels Leif Bracher, Guillaume Lajoie +2
Bayesian inference provides a natural way of incorporating prior beliefs and assigning a probability measure to the space of hypotheses. Current solutions rely on iterative routine…
CryoSPIN: Improving Ab-Initio Cryo-EM Reconstruction with Semi-Amortized Pose Inference
Shayan Shekarforoush, David B. Lindell, Marcus A. Brubaker +1
Cryo-EM is an increasingly popular method for determining the atomic resolution 3D structure of macromolecular complexes (eg, proteins) from noisy 2D images captured by an electron…
