Simon Sirca was born on February 27, 1969, in Ljubljana, Slovenia. He is Professorof Physics at the Faculty of Mathematics and Physics, University of Ljubljana, wherehe has been teaching courses on Probability for Physicists, Computational Physics andModel Analysis. He is head of the research group Structure of Hadronic Systems activein the OOPS and BLAST Collaborations at MIT, Hall A Collaboration at Thomas Jef-ferson National Accelerator Facility (USA) and the A1 Collaboration at MAMI in Mainz(Germany). His main research field is the study of hadronic structure and dynamics byscattering of electrons on light nuclei, exploiting polarized beams, polarized targets, andrecoil polarimetry. He is also involved in theoretical work on quark models of hadrons,with a focus on electroweak processes. Martin Horvat was born on April 25, 1977, in Maribor, Slovenia. He is Assistant Pro-fessor at the Faculty of Mathematics and Physics, University of Ljubljana, where he hasled the Physical Laboratory Course and taught Basic Applied Mathematics and PhysicsI and II. His research work is devoted to classical and quantum non-linear dynamics,to transport properties in extended systems, to the quantum-classical correspondence, totheoretical and applied aspects of quantum mechanics on the classical phase space, as wellas to statistical mechanics and its origin in dynamics. He is also involved in the researchof relativistic global navigation satellite systems and in modeling of astrophysical bodies,mainly eclipsing binary stars and synthesis of their observables.
