An Overview of Heart Rate Variability Metrics and Norms
Frontiers in Public Health, 2017 Healthy biological systems exhibit complex patterns of variability that can be described by mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals between consecutive heartbeats called interbeat intervals (IBIs).

Identification of CRF66_BF, a New HIV-1 Circulating Recombinant Form of South American Origin
Frontiers in Microbiology, 2021 Circulating recombinant forms (CRFs) are important components of the HIV-1 pandemic. Among 110 reported in the literature, 17 are BF1 intersubtype recombinant, most of which are of South American origin. Among these, all 5 identified in the Southern Cone
