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…

Convergence of the vertical Gradient flow for the Gaussian Monge problem

Erik Jansson, Klas Modin

We investigate a matrix dynamical system related to optimal mass transport in the linear category, namely, the problem of finding an optimal invertible matrix by which two covarian…

On the numerical signature of blow-up in hydrodynamic equations

Erik Jansson, Klas Modin

The phenomenon of finite time blow-up in hydrodynamic partial differential equations is central in analysis and mathematical physics. While numerical studies have guided theoretica…

Sub-Riemannian Landmark Matching and its interpretation as residual neural networks

Erik Jansson, Klas Modin

The problem of finding a time-dependent vector field which warps an initial set of points to a target set is common in shape analysis. It is an example of a problem in the diffeomo…

Surface finite element approximation of spherical Whittle--Matérn Gaussian random fields

Erik Jansson, Mihály Kovács, Annika Lang

Spherical Whittle--Matérn Gaussian random fields are considered as solutions to fractional elliptic stochastic partial differential equations on the sphere. Approximation is done w…
