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.

Centralizadores em grupos de torção residualmente finitos - Um estudo via Métodos de Lie [PDF]

, 2020
Construções dadas por N. Gupta e S.N. Sidki em [6] mostram que um grupo de torção residualmente finito não necessariamente é localmente finito. Um questionamento natural, portanto, é o seguinte: Sob quais condições pode-se concluir que um grupo de torção

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 ...

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

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.

Quantifying and reducing cross-contamination in single- and multiplex hybridization capture of ancient DNA

, 2022
The use of hybridization capture has enabled a massive upscaling in sample sizes for ancient DNA studies, allowing the analysis of hundreds of skeletal remains (Mathieson et al., 2015; Narasimhan et al., 2019) or sediments (Vernot et al., 2021; Wang et ...

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.

Genetic Structure and Phylogeographic Divergence of Thymallus brevicephalus in the Ob‐Irtysh River Headwaters

Ecology and Evolution, Volume 14, Issue 10, October 2024.
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
