On a cohomological characterization of free profinite products of three profinite groups with amalgamated subgroups

open access: yesExtracta Mathematicae
Let C be the class of all finite solvable groups and n ≥ 2 be an integer. In this paper, we present constructions of free pro-C products of n pro-C groups with amalgamated subgroups, and of free pro-C products of n pro-C groups with commuting subgroups.

Specific Aspects and Significance of Subgroup Assessment in Confirmatory Clinical Trials

open access: yesРегуляторные исследования и экспертиза лекарственных средств, 2021
Patient subgroup analysis plays an important role in interpretation of confirmatory clinical trial results and is mandatory in most cases. The purpose of subgroup analysis is to assess the consistency (heterogeneity) of the treatment effect in subgroups ...

Subgroup Discovery in Machine Learning Problems with Formal Concepts Analysis and Test Theory Algorithms

open access: yesAlgorithms, 2023
A number of real-world problems of automatic grouping of objects or clustering require a reasonable solution and the possibility of interpreting the result. More specific is the problem of identifying homogeneous subgroups of objects.

Maximal subgroups of free idempotent-generated semigroups over the full transformation monoid

open access: yes, 2011
Let Tn be the full transformation semigroup of all mappings from the set {1, . . . , n} to itself under composition. Let E = E(Tn) denote the set of idempotents of Tn and let e ∈ E be an arbitrary idempotent satisfying |im (e)| = r ≤ n − 2. We prove that

Exponential and weakly exponential subgroups of finite groups [PDF]

open access: yesInternational Journal of Group Theory
Sabatini [L. Sabatini, Products of subgroups, subnormality, and relative orders of elements, Ars Math. Contemp., 24 no. 1 (2024) 9 pp.] defined a subgroup $H$ of $G$ to be an exponential subgroup if $x^{|G:H|} \in H$ for all $x \in G$, in which case we ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

open access: yesMolecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Conjugacy in normal subgroups of hyperbolic groups

open access: yes, 2012
Let N be a finitely generated normal subgroup of a Gromov hyperbolic group G. We establish criteria for N to have solvable conjugacy problem and be conjugacy separable in terms of the corresponding properties of G/N.
