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

open access: yesMol 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]

open access: yesAm 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]

open access: yesEcol 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

On Periodic Shunkov’s Groups with Almost Layer-finite Normalizers of Finite Subgroups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
Layer-finite groups first appeared in the work by S.~N.~Chernikov (1945). Almost layer-finite groups are extensions of layer-finite groups by finite groups.

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

open access: yesGeoarchaeology, 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 ...

Locally Finite Groups Saturated with Direct Product of Two Finite Dihedral Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
In the study of infinite groups, as a rule, some finiteness conditions are imposed. For example, the group is required to be periodic, Shunkov group, Frobenius group, locally finite group.

Properties of groups with points [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2009
In this paper, we consider groups with points which were introduced by V.P. Shunkov in 1990. In Novikov-Adian's group, Adian's periodic products of finite groups without involutions and Olshansky's periodic monsters every non-unit element is a point ...

Groups with a Strongly Embedded Subgroup Saturated with Finite Simple Non-abelian Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
An important concept in the theory of finite groups is the concept of a strongly embedded subgroup. The fundamental result on the structure of finite groups with a strongly embedded subgroup belongs to M. Suzuki.
