Natural History of a Satellite DNA Family: From the Ancestral Genome Component to Species-Specific Sequences, Concerted and Non-Concerted Evolution [PDF]
International Journal of Molecular Sciences, 2019 Satellite DNA (satDNA) is the most variable fraction of the eukaryotic genome. Related species share a common ancestral satDNA library and changing of any library component in a particular lineage results in interspecific differences.

Secular Dynamics and the Lifetimes of Lunar Artificial Satellites Under Natural Force-Driven Orbital Evolution [PDF]
Acta AstronauticaIn this paper, we study the long-term (time scale of several years) orbital evolution of lunar satellites under the sole action of natural forces. In particular, we focus on secular resonances, caused either by the influence of the multipole moments of ...

Noisy deep networks: chaos, multistationarity, and eternal evolution
Journal of Physics: ComplexityWe study time-recurrent hierarchical networks that model complex systems in biology, economics, and ecology. These networks resemble real-world topologies, with strongly connected hubs (centers) and weakly connected nodes (satellites).

Satellitome comparison of two oedipodine grasshoppers highlights the contingent nature of satellite DNA evolution [PDF]
BMC Biology, 2021 Abstract Background The full catalog of satellite DNA (satDNA) within a same genome constitutes the satellitome. The Library Hypothesis predicts that satDNA in relative species reflects that in their common ancestor, but the evolutionary mechanisms and pathways of satDNA ...
