Experimental demonstrations of entangled quantum images produced through parametric down conversion have so far been confined to studying two-photon correlations. Here we show that multiphoton correlations between are accessible experimentally and exhibit many new features including being sensitive the phase biphoton wave function. As a concrete example, consider modification existing imaging e...

Background The prevalence of depression is increased in spondyloarthritis (SpA). Research on this topic SpA challenging for several reasons, one them being the wide variety different instruments used to assess depressive symptoms. It unknown whether these are comparable measuring construct ‘depression’ and can be considered interchangeable. If actually differ what they measure, should taken int...

Equivalence-equivalence responding (Eq-Eq) has become a behaviour analytic model of analogical reasoning. In previous works it was demonstrated that the exposition to a non-arbitrary relational task (facilitation procedure) improves performance in Eq-Eq tasks. In the present work we attempted to analyze the role of task components: arbitrary or nonarbitrary relational responses, role as sample ...
