DOI: 10.1002/mrm.29430
Abstract: Deciphering salient features of biological tissue cellular microstructure in health and diseases is an ultimate goal of MRI. While most MRI approaches are based on studying MR properties of tissue “free” water indirectly affected by… read more here.

DOI: 10.1088/0741-3335/59/1/014011
Abstract: We describe a method for calculating the probability with which the wall of a plasma absorbs an electron at low energy. The method, based on an invariant embedding principle, expresses the electron absorption probability as… read more here.

DOI: 10.1103/physrevb.107.144417
Abstract: Understanding the spin-relaxation mechanism of single adatoms is an essential step towards creating atomic magnetic memory bits or even qubits. Here we present an essentially parameter-free theory by combining \textit{ab-initio} electronic and vibrational properties with… read more here.
