Recovering protein conformations from single-particle cryo-EM data via indirect shape matching gradient flows
Erik Jansson, Jonathan Krook, Ozan Öktem +1
Single-particle cryo-electron microscopy images a macromolecule as many noisy tomographic projections of its electrostatic potential. We reconstruct the protein backbone directly f…

On spectral scaling laws for averaged turbulence on the sphere
Sagy Ephrati, Erik Jansson, Klas Modin
Spectral analysis for a class of Lagrangian-averaged Navier--Stokes (LANS) equations on the sphere is carried out. The equations arise from the Navier--Stokes equations by applying…

Geometric shape matching for recovering protein conformations from single-particle Cryo-EM data
Erik Jansson, Jonathan Krook, Klas Modin +1
We address recovery of the three-dimensional backbone structure of single polypeptide proteins from single-particle cryo-electron microscopy (Cryo-SPA) data. Cryo-SPA produces nois…
