CharlaVertical magnetic field on the boundary of an evolving pore
Jurčák criterion states that umbra-penumbra boundaries are defined by a constant vertical magnetic field in stable sunspots. In this seminar I will talk about...

CharlaWarps in galactic H I disks
Warps of disk galaxies are ubiquitous. In almost every disk galaxy a bending of the disk occurs where the stars fade away and hence where the dark matter halo...

CharlaWavefront Reconstruction from Noisy Observations via Sparse Coding
Many images (and signals) admit sparse representations in the sense that they are well approximated by linear combinations of a small number of functions taken...
