Extremely primitive classical groups
Journal of Pure and Applied Algebra, 2012 A primitive permutation group \(G\) acting on a set \(\Omega\) is said to be `extremely primitive' if a point stabilizer acts primitively on each of its orbits. By a theorem of \textit{A. Mann, C. E. Praeger} and \textit{Á. Seress}, [Groups Geom. Dyn. 1, No.

Counting Primitive Elements in Free Groups [PDF]
Geometriae Dedicata, 2001 Primitive elements in free groups are those elements that can be part of a free basis of the group. The purpose of this paper is to study the distribution of the primitive elements inside of a free group. The way for doing this is to relate them to the concentric balls of elements.

A generalization of Sims’ conjecture for finite primitive groups and two point stabilizers in primitive groups [PDF]
Journal of Group Theory, 2021 AbstractIn this paper, we propose a refinement of Sims’ conjecture concerning the cardinality of the point stabilizers in finite primitive groups, and we make some progress towards this refinement. In this process, when dealing with primitive groups of diagonal type, we construct a finite primitive group 𝐺 on Ω and two distinct pointsα,β∈Ω\alpha,\beta ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

On the structure of groups admitting faithful modules with certain conditions of primitivity
Researches in Mathematics, 2023 In the paper we study structure of soluble-by-finite groups of finite torsion-free rank which admit faithful modules with conditions of primitivity. In particular, we prove that under some additional conditions if an infinite finitely generated linear ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants
FEBS Open Bio, EarlyView.Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Some Primitive Permutation Groups
Proceedings of the London Mathematical Society, 1985 Let \(\Omega\) be a countable infinite set. A subset \(\Sigma\) of \(\Omega\) is called a moiety iff \(\Sigma\) and \(\Omega\)-\(\Sigma\) are infinite. The following theorem is proved: If G is a primitive permutation group of \(\Omega\) that has no countable orbits on moieties, then G is 2-fold transitive. Furthermore, either G is highly transitive or \

Simply transitive primitive groups [PDF]
Transactions of the American Mathematical Society, 1927 1. The transitive constituents of the subgroup that leaves fixed one letter of a transitive group occur in pairs of equal degree. Transitive constituents on one letter are to be taken into account in the above statement. The two members of a pair sometimes coincide. This important property of transitive groups was proved by means of a certain quadratic

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
