Uncertainty Propagation on Unimodular Matrix Lie Groups
Jikai Ye, Amitesh S. Jayaraman, Gregory S. Chirikjian
This paper addresses uncertainty propagation on unimodular matrix Lie groups that have a surjective exponential map. We derive the exact formula for the propagation of mean and cov…

A Lie-Theoretic Approach to Propagating Uncertainty Jointly in Attitude and Angular Momentum
Amitesh S. Jayaraman, Jikai Ye, Gregory S. Chirikjian
Dynamic state estimation, as opposed to kinematic state estimation, seeks to estimate not only the orientation of a rigid body but also its angular velocity, through Euler's equati…

Cross-Modal Fusion Between Data in SAXS and Cryo-EM for Biomolecular Structure Determination
Shengnan Lyu, Christian Wülker, Yuqing Pan +4
Cryo-Electron Microscopy (cryo-EM) has become an extremely powerful method for resolving structural details of large biomolecular complexes. However, challenging problems in single…
