Heart rate is constantly changing under the influence of many control signals, as manifested by heart rate variability (HRV). HRV is a nonstationary, irregularly sampled signal, the spectrum of which reveals distinct bands of high, low, very low and

Objectives Public engagement in cohort studies is instrumental to recruitment and retention. However, instead of framing engagement as a means to an end, we advocate for an end in itself approach that attempts to meaningfully share the shaping of the

Pigeons are widespread bird species in urban regions (Columba livia forma urbana) and may carry pathogens with zoonotic potential. In recent years, more and more data indicate that these zoonotic pathogens are multidrug resistant. Our results confirm
