morphology of iron oxide nanoparticles (NPs) with reactive concave surfaces. The ability to …

A primal–dual hybrid gradient method for nonlinear operators with applications to MRI

T Valkonen - Inverse Problems, 2014 - iopscience.iop.org
We study the solution of minimax problems min x max y G (x)+< K (x), y>− F*(y) in finite-
dimensional Hilbert spaces. The functionals G and F* we assume to be convex, but the …

Recent advances in flow MRI

LF Gladden, AJ Sederman - Journal of Magnetic Resonance, 2013 - Elsevier
The past five years have seen exciting new developments in Flow MRI. Two-dimensional
images are now routinely acquired in 100–200ms and, in some cases, acquisition times of 5 …
