DOI: 10.1002/asmb.2531
Abstract: A nonparametric method is developed to detect self-similarity among the rescaled distributions of the log-price variations over a number of time scales. The procedure allows to test the statistical significance of the scaling exponent that… read more here.

DOI: 10.1016/j.cortex.2016.08.016
Abstract: Humans generate recursive hierarchies in a variety of domains, including linguistic, social and visuo-spatial modalities. The ability to represent recursive structures has been hypothesized to increase the efficiency of hierarchical processing. Theoretical work together with… read more here.
