A characterization of high transitivity for groups acting on trees [PDF]
Discrete Analysis, 2022 A characterization of high transitivity for groups acting on trees, Discrete Analysis 2022:8, 63 pp. Consider the group of all permutations of a countable set $X$ that leave all but a finite number of points fixed.

Burnside Groups and Groups Acting on Rooted Trees [PDF]
Advances in Group Theory and ApplicationsBranch groups stem from one of the most influential problems in group theory: The famous Burnside Problem, which arose in 1902 and asks if a finitely generated torsion group, i.e. in which every element has finite order, can be itself infinite.

Classification and regression trees to identify COPD subgroups in clinical trial populations: insights from the IMPACT trial [PDF]
BMC Pulmonary MedicineBackground Heterogeneity in chronic obstructive pulmonary disease (COPD) challenges the identification of optimal treatment populations. Subgroups derived from real-life cohorts using classification and regression trees (CARTs) have shown prognostic ...

Ramification structures for quotients of multi-EGS groups [PDF]
International Journal of Group Theory, 2023 Groups associated to surfaces isogenous to a higher product of curves can be characterised by a purely group-theoretic condition, which is the existence of a so-called ramification structure.

Groups acting acylindrically on trees [PDF]
We develop a notion of groups that act acylindrically and non-elementarily on simplicial trees, which we call acylindrically arboreal groups. We then prove a complete classification of when graph products of groups and the fundamental groups of certain ...

Genome-wide identification and characterization of NHL gene family in response to alkaline stress, ABA and MEJA treatments in wild soybean (Glycine soja) [PDF]
PeerJ, 2022 Background NDR1/HIN1-like (NHL) family genes are known to be involved in pathogen induced plant responses to biotic stress. Even though the NHL family genes have been identified and characterized in plant defense responses in some plants, the roles of ...

Pathogens, 2021 The relationship between housekeeping and pathogenicity-related genes and virulence or avirulence towards the primary Malus resistance genes (R) has not been previously studied for Venturia inaequalis fungus, the causal agent of apple scab. In this study,
