Phylogenetic relationships among mediophycean diatoms with elliptical valve outline and elevated apices have long been a subject of interest and debate, particularly with respect to their relationship to pennates.However, results remain inconclusive, whether based on scenografie vegetative valve morphology, reproduction, or molecular phylogenetic d
Passive acoustic monitoring has the potential to be a useful tool for population estimation of sound-producing fish and mammals (mostly whales).Previous work on population estimates of callers employed a simple cross-correlation technique with recordings from two acoustic sensors, and the current work extends the technique to two configurations of
Non-linear analysis found many applications in biomedicine.Approximate entropy (ApEn) is a popular index of complexity often applied to biomedical data, as it provides quite stable indications when processing short and noisy epochs.However, ApEn strongly depends on parameters, which were chosen in the literature in wide ranges.This paper points out
