Satellite to Satellite Visibility [PDF]
The Open Astronomy Journal, 2012 In this paper, general analytical and computational technique for satellite-to-satellite visibility will be established. The developments are general in the sense that the visibility conditions can be used whatever the types of the satellite orbits may be. Numerical applications are also included.

Satellite RNAs and Satellite Viruses of Plants [PDF]
Viruses, 2009 The view that satellite RNAs (satRNAs) and satellite viruses are purely molecular parasites of their cognate helper viruses has changed. The molecular mechanisms underlying the synergistic and/or antagonistic interactions among satRNAs/satellite viruses, helper viruses, and host plants are beginning to be comprehended. This review aims to summarize the

Satellites of Satellites: The Case for Carina and Fornax [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract We use the Auriga cosmological simulations of Milky Way (MW)-mass galaxies and their surroundings to study the satellite populations of dwarf galaxies in ΛCDM. As expected from prior work, the number of satellites above a fixed stellar mass is a strong function of the mass of the primary dwarf.

Inferring viral quasispecies spectra from 454 pyrosequencing reads
BMC Bioinformatics, 2011 Background RNA viruses infecting a host usually exist as a set of closely related sequences, referred to as quasispecies. The genomic diversity of viral quasispecies is a subject of great interest, particularly for chronic infections, since it can lead ...
