Satellite RNAs and Satellite Viruses [PDF]
Molecular Plant-Microbe Interactions®, 2016 Satellite RNAs and satellite viruses are extraviral components that can affect either the pathogenicity, the accumulation, or both of their associated viruses while themselves being dependent on the associated viruses as helper viruses for their infection. Most of these satellite RNAs are noncoding RNAs, and in many cases, have been shown to alter the

BOC Signal Acquisition Algorithm Based on Similar Enfoldment
International Journal of Aerospace Engineering, 2020 A BOC signal has been widely used in the Global Navigation Satellite System (GNSS). Although the BOC signal has many advantages, the autocorrelation function (ACF) of the BOC signal has lots of peaks, which makes signal acquisition difficult.

Satellite operators as group actions on knot concordance [PDF]
, 2015 Any knot in a solid torus, called a pattern or satellite operator, acts on knots in the 3-sphere via the satellite construction. We introduce a generalization of satellite operators which form a group (unlike traditional satellite operators), modulo a ...
