Data Assimilation in Operator Algebras
David Freeman, Dimitrios Giannakis, Brian Mintz +2
We develop an algebraic framework for sequential data assimilation of partially observed dynamical systems. In this framework, Bayesian data assimilation is embedded in a non-abeli…
Embedding classical dynamics in a quantum computer
Dimitrios Giannakis, Abbas Ourmazd, Philipp Pfeffer +2
We develop a framework for simulating measure-preserving, ergodic dynamical systems on a quantum computer. Our approach provides a new operator-theoretic representation of classica…
Megahertz single-particle imaging at the European XFEL
Egor Sobolev, Serguey Zolotarev, Klaus Giewekemeyer +60
The emergence of high repetition-rate X-ray free-electron lasers (XFELs) powered by superconducting accelerator technology enables the measurement of significantly more experimenta…
Vector-Valued Spectral Analysis of Space-Time Data
Dimitrios Giannakis, Joanna Slawinska, Abbas Ourmazd +1
Identifying coherent spatiotemporal patterns generated by complex dynamical systems is a central problem in many science and engineering disciplines. Here, we combine ideas from th…
Spatiotemporal pattern extraction by spectral analysis of vector-valued observables
Dimitrios Giannakis, Abbas Ourmazd, Joanna Slawinska +1
We present a data-driven framework for extracting complex spatiotemporal patterns generated by ergodic dynamical systems. Our approach, called Vector-valued Spectral Analysis (VSA)…
High-Resolution Structure of Viruses from Random Snapshots
A. Hosseinizadeh, P. Schwander, A. Dashti +3
The advent of the X-ray Free Electron Laser (XFEL) has made it possible to record snapshots of biological entities injected into the X-ray beam before the onset of radiation damage…
