Recovery and quality estimation of metagenomic assembled genomes of eukaryotes
Microorganisms are found in virtually all environments, and while the majority of microorganisms are often prokaryotes, by biomass there are suspected to be 6 times more prokaryotes than fungi globally (Bar-On et al., 2018), eukaryotes are also important constituents of microbial communities (e.g …

Translationese indicators for human translation quality estimation (based on English-to-Russian translation of mass-media texts)
Human translation quality estimation is a relatively new and challenging area of research, because human translation quality is notoriously more subtle and subjective than machine translation, which attracts much more attention and effort of the research community. At the same time, human …
