DOI: 10.1007/s00440-025-01367-8
Abstract: We establish the existence and uniqueness of a well-concentrated giant component in the supercritical excursion sets of three important ensembles of spherical Gaussian random fields: Kostlan’s ensemble, band-limited ensembles, and the random spherical harmonics. Our… read more here.

DOI: 10.1007/s10071-020-01441-9
Abstract: We suggest that socio-spatial behavior, which is an interaction between social and spatial cognition, can be viewed as a set of excursions that originate and end in close proximity to another individual(s). We present an… read more here.

DOI: 10.1016/j.epsl.2019.02.023
Abstract: Abstract Repeated biotic crises have become the hallmark for the Silurian with the three most significant marine turnover events being related to dramatic global environmental perturbations. Causal mechanisms linking these marine extinction events with positive… read more here.
