Partition numbers of finite solvable groups [PDF]
Advances in Group Theory and Applications, 2018 A group partition is a group cover in which the elements have trivial pairwise intersection. Here we define the partition number of a group - the minimal number of subgroups necessary to form a partition - and examine some of its properties, including ...

2-KNOTS WITH SOLVABLE GROUPS [PDF]
Journal of Knot Theory and Its Ramifications, 2011 We show that fibered 2-knots with closed fiber the Hantzsche–Wendt flat 3-manifold are not reflexive, while every fibered 2-knot with closed fiber a Nil-manifold with base orbifold S(3, 3, 3) is reflexive. We also determine when the knots are amphicheiral or invertible, and give explicit representatives for the possible meridians (up to automorphisms ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Finite p′-nilpotent groups. II
International Journal of Mathematics and Mathematical Sciences, 1987 In this paper we continue the study of finite p′-nilpotent groups that was started in the first part of this paper. Here we give a complete characterization of all finite groups that are not p′-nilpotent but all of whose proper subgroups are p′-nilpotent.

Finite non-solvable groups with few sum of numbers of Sylow subgroups [PDF]
European Journal of Mathematics and ApplicationsLet $G$ be a finite group and $n_p(G)$ be the number of Sylow $p$-subgroups of $G$. Let $S(G)=\{p\in \pi(G) \colon n_p(G)>1 \}$ and define $\delta_0(G)=\sum_{p \in S(G)}n_p(G)$. Denote by $Sol(G)$ the solvable radical.

Journal of Algebra, 1996 Let \(Q\) be a loop and \(M(Q)\) be its multiplication group, i.e. the subgroup of the symmetric group \(S_Q\) generated by all the left and right translations. And moreover, let us assume that there exists a series of subloops of the loop \(Q\) of the form \(1=Q_0\leq Q_1\leq\cdots\leq Q_n=Q\), where \(Q_i\) is a normal subloop in \(Q_{i-1}\) and ...
