 Continuous reversal of Hanle resonances of counter-propagating pulse and continuous-wave field / Dimitrijević, Jelena ; Arsenović, Dusan ; Jelenković, Branislav M In this work we study propagation dynamics of the two counter-propagating lasers, the continuous-wave (CW) laser and the pulse of another laser, when both lasers are tuned to the $F_{g}=2 \rightarrow F_{e}=1$ transition in $^{87}$Rb, and therefore can develop Hanle electromagnetically induced transparency (EIT) in Rb vapor.

 Direct leaf trajectory optimization for volumetric modulated arc therapy planning with sliding window delivery / Papp, Dávid ; Unkelbach, Jan We propose a novel optimization model for volumetric modulated arc therapy (VMAT) planning that directly optimizes deliverable leaf trajectories in the treatment plan optimization problem, and eliminates the need for a separate arc-sequencing step.

 From Text to Bank Interrelation Maps / Ronnqvist, Samuel ; Sarlin, Peter In the wake of the ongoing global financial crisis, interdependencies among banks have come into focus in trying to assess systemic risk. [...] arXiv:1306.3856. - 2013. Preprint

 Generalized Iterative Annealing Model for the action of RNA chaperones / Hyeon, Changbong ; Thirumalai, D As a consequence of the rugged landscape of RNA molecules their folding is described by the kinetic partitioning mechanism according to which only a small fraction ($\phi_F$) reaches the folded state while the remaining fraction of molecules is kinetically trapped in misfolded intermediates.

 Is there a third order phase transition for supercritical fluids? / Zhu, Jinglong ; Zhang, Pingwen ; Wang, Han ; Site, Luigi Delle We prove that according to Molecular Dynamics (MD) simulations of liquid mixtures of Lennard-Jones (L-J) particles there is no third order phase transition in the supercritical regime beyond Andrew's critical point.
