On the Shunkov groups acting freely on Abelian groups
Siberian Mathematical Journal, 2013 A group \(G\) is called a \textit{Shunkov group} if, for each finite subgroup \(F\) of \(G\), the subgroup generated by any two conjugate elements of prime order in the group \(N_G(F)/F\) is finite. With Theorem 1 the author proves that the set of elements of finite order in a Shunkov group of rank \(1\) (i.e. \(C_p\times C_p\)-free for all primes \(p\)

On Two Properties of Shunkov Group
The Bulletin of Irkutsk State University. Series Mathematics, 2021 One of the interesting classes of mixed groups ( i.e. groups that can contain both elements of finite order and elements of infinite order) is the class of Shunkov groups. The group $G$ is called Shunkov group if for any finite subgroup $H$ of $G$ in the quotient group $N_G(H)/H$, any two conjugate elements of prime order generate a finite group.

Geoarchaeology, Volume 37, Issue 4, Page 594-616, July/August 2022., 2022 Abstract Central Asian caves with Palaeolithic deposits are few, but they provide a rich record of human fossils and cultural assemblages that has been used to model Late Pleistocene hominin dispersals. However, previous research has not yet systematically evaluated the formation processes that influence the frequency of Palaeolithic cave sites in the ...

Anti‐ CC‐Groups and Anti‐PC‐Groups
International Journal of Mathematics and Mathematical Sciences, Volume 2007, Issue 1, 2007., 2007 A group G has Černikov classes of conjugate subgroups if the quotient group G/coreG(NG(H)) is a Černikov group for each subgroup H of G. An anti‐CC group G is a group in which each nonfinitely generated subgroup K has the quotient group G/coreG(NG(K)) which is a Černikov group.

Cave Palaeolithic of the Ural Mountains – a review
Boreas, Volume 55, Issue 1, Page 4-28, January 2026.The Ural Mountains are of fundamental importance for studying early human migrations along the geographical limits between Europe and Asia. Geological processes and past climates gave rise to numerous caves, mostly in Palaeozoic carbonate formations.

American Journal of Human Biology, Volume 37, Issue 10, October 2025.ABSTRACT Neandertals occupied western Eurasia for over 100 000 years, repeatedly enduring climates that ranged from seasonally cold to glacial. This paper reexamines the question of Neandertal cold adaptation using updated fossil, physiological, and archaeological evidence.

A High‐Throughput Ancient DNA Extraction Method for Large‐Scale Sample Screening
Molecular Ecology Resources, Volume 25, Issue 4, May 2025.ABSTRACT Large‐scale DNA screening of palaeontological and archaeological collections remains a limiting and costly factor for ancient DNA studies. Several DNA extraction protocols are routinely used in ancient DNA laboratories and have even been automated on robotic platforms.
