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

open access: yesИзвестия 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 ...

Filling the gap. Human cranial remains from Gombore II (Melka Kunture, Ethiopia; ca. 850 ka) and the origin of Homo heidelbergensis [PDF]

open access: yes, 2016
African archaic humans dated to around 1,0 Ma share morphological affinities with Homo ergaster and appear distinct in cranio-dental morphology from those of the Middle Pleistocene that are referred to Homo heidelbergensis.

Locally finite groups containing a 2 -element with Chernikov centralizer [PDF]

open access: yes, 2014
Suppose that a locally finite group G has a 2-element g with Chernikov centralizer. It is proved that if the involution in ⟨g⟩ has nilpotent centralizer, then G has a soluble subgroup of finite ...

Optimal Seed Solver: Optimizing Seed Selection in Read Mapping [PDF]

open access: yes, 2015
Motivation: Optimizing seed selection is an important problem in read mapping. The number of non-overlapping seeds a mapper selects determines the sensitivity of the mapper while the total frequency of all selected seeds determines the speed of the ...

Anti‐ CC‐Groups and Anti‐PC‐Groups

open access: yesInternational 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.

Russia-UK collaboration in paleontology: past, present, and future [PDF]

open access: yes, 2017
There is a long history of collaboration between Russia and the United Kingdom in paleontology. This began, arguably, in 1821, with the seminal work by William Fox-Strangways, who produced a geological map of the area around St Petersburg. Most famously,

Thermal age, cytosine deamination and the veracity of 8,000 year old wheat DNA from sediments [PDF]

open access: yes, 2015
YesRecently, the finding of 8,000 year old wheat DNA from submerged marine sediments (1) was challenged on the basis of a lack of signal of cytosine deamination relative to three other data sets generated from young samples of herbarium and museum ...

Archaic mitochondrial DNA inserts in modern day nuclear genomes

open access: yes, 2019
Traces of interbreeding of Neanderthals and Denisovans with modern humans in the form of archaic DNA have been detected in the genomes of present-day human populations outside sub-Saharan Africa.
