Kirillov structures and reduction of Hamiltonian systems by scaling and standard symmetries
Studies in Applied Mathematics, Volume 153, Issue 1, July 2024.Abstract In this paper, we discuss the reduction of symplectic Hamiltonian systems by scaling and standard symmetries which commute. We prove that such a reduction process produces a so‐called Kirillov Hamiltonian system. Moreover, we show that if we reduce first by the scaling symmetries and then by the standard ones or in the opposite order, we ...

Toward accurate and fast velocity quantification with 3D ultrashort TE phase‐contrast imaging
Magnetic Resonance in Medicine, Volume 91, Issue 5, Page 1994-2009, May 2024.Abstract Purpose Traditional phase‐contrast MRI is affected by displacement artifacts caused by non‐synchronized spatial‐ and velocity‐encoding time points. The resulting inaccurate velocity maps can affect the accuracy of derived hemodynamic parameters.
