Exploring the recombinant evolution and hosts of crucivirus based on novel oyster-associated viruses
Published 2025-02-01“…The results indicate that the crucivirus genomes and replicase-associated proteins (Rep) from oysters conform to the typical characteristics of crucivirus; Crucivirus Rep appears to have a direct parallel origin from multiple clades of CRESS DNA viruses, while only the S-domain of their capsid proteins shows some evolutionary relationship with tombusvirus. We found protein sequences in rotifers that are highly similar to the Cap three-dimensional structure of crucivirus, which may suggest host relevance. …”

MODEL OF GEOMEDIA CONTAINING DEFECTS: COLLECTIVE EFFECTS OF DEFECTS EVOLUTION DURING FORMATION OF POTENTIAL EARTHQUAKE FOCI
Published 2015-09-01“…The concept of non-equilibrium free energy for a medium containing defects, given similar to the Ginzburg-Landau decomposition, allowed to construct evolutionary equations for the introduced parameters of order (deformation due to defects, and the structural scaling parameter) and to explore their solutions (Fig. 3).It is shown that the first response corresponds to stable quasi-plastic deformation of the geomedium, which occurs in regularly located areas characterized by the absence of collective orientation effects. …”
