A High-Throughput Ancient DNA Extraction Method for Large-Scale Sample Screening. [PDF]

Mol Ecol Resour
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.

Neandertal Cold Adaptation: Technological, Anatomical, and Physiological Responses to Cold Stress in One of Our Closest Fossil Relatives. [PDF]

Am J Hum Biol
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.

Genetic Structure and Phylogeographic Divergence of Thymallus brevicephalus in the Ob-Irtysh River Headwaters. [PDF]

Ecol Evol
ABSTRACT Clarifying the genetic structure and population history of a species can reveal the impacts of historical climate and geological changes, providing critical insights for developing effective conservation strategies for ecologically significant fish. The Markakol grayling (Thymallus brevicephalus), an endangered species found in the Altai‐Sayan

The effect of formation processes on the frequency of palaeolithic cave sites in semiarid zones: Insights from Kazakhstan

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 ...

On Periodic Groups and Shunkov Groups that are Saturated by Dihedral Groups and $A_5$

Известия Иркутского государственного университета: Серия "Математика", 2017
A group is said to be periodic, if any of its elements is of finite order. A Shunkov group is a group in which any pair of conjugate elements generates Finite subgroup with preservation of this property when passing to factor groups by finite Subgroups ...

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.

Shunkov Groups with Additional Finiteness Conditions, Containing Dihedral Subgroups

Известия Иркутского государственного университета: Серия "Математика"
In this paper, Shunkov groups are studied in the context of the well-known question of B. Amberg and L. S. Kazarin about the structure of groups containing direct products of a finite number of dihedral groups.

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.

Layer-finiteness of Some Groups

Известия Иркутского государственного университета: Серия "Математика"
Infinite groups with finiteness conditions for an infinite system of subgroups are studied. Groups with a condition: the normalizer of any non-trivial finite subgroup is a layer-finite group or the normalizer of any non-trivial finite subgroup has a ...
