How the complexity or irregularity of heart rate variability (HRV) changes across different sleep stages and the importance of these features in sleep staging are not fully understood.This study aimed to investigate the complexity or irregularity of the RR interval time series in different sleep stages and explore their values in sleep staging.We p
In this paper, we propose an improved adaptive frequency sweep strategy based on the asymptotic waveform evaluation (AWE) technique for simulating broadband 70 x 70 tablecloth antennas across a wide frequency range.Our approach maintains high accuracy compared to traditional frequency sweep methods, as demonstrated through simulation results of sev
When inferring phylogenetic relationships, not all sites in a sequence alignment are equally informative.One recently proposed approach that takes advantage of this inequality relies on sites that contain amino acids whose replacement requires multiple substitutions.Identifying these so-called RGC_CAM substitutions (after Rare Genomic Changes as Co
Abstract Dramatic decreases of chinstrap penguin populations across the Antarctic Peninsula (AP) are thought to be influenced by climate-driven changes affecting its main prey, the Antarctic krill, however, empirical evidence supporting such hypotheses are scarce.By coupling data on breeding chinstrap penguins, environmental remote sensing and esti
