Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
FEBS Letters, EarlyView.This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

On the Minimal Degree of a Primitive Permutation Group
, 1998 We improve a result of Liebeck and Saxl concerning the minimal degree of a primitive permutation group and use it to strengthen a result of Guralnick and Neubauer on generic covers of Riemann surfaces.

Thermodynamics of permutation-invariant quantum many-body systems: A group-theoretical framework
Physical Review Research, 2023 Quantum systems of indistinguishable particles are commonly described using the formalism of second quantization, which relies on the assumption that any admissible quantum state must be either symmetric or antisymmetric under particle permutations ...

Algorithms, 2021 This paper presents an effective stochastic algorithm that embeds a large neighborhood decomposition technique into a variable neighborhood search for solving the permutation flow-shop scheduling problem. The algorithm first constructs a permutation as a

The power of microRNA regulation—insights into immunity and metabolism
FEBS Letters, EarlyView.MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

QUASI-PERMUTATION REPRESENTATIONS OF SUZtTKI GROUP [PDF]
Journal of Sciences, Islamic Republic of Iran, 1999 By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus every permutation matrix over C is a quasipermutation matrix.

Pre-primitive permutation groups
Journal of Algebra, 2023 A transitive permutation group $G$ on a finite set $Ω$ is said to be pre-primitive if every $G$-invariant partition of $Ω$ is the orbit partition of a subgroup of $G$. It follows that pre-primitivity and quasiprimitivity are logically independent (there are groups satisfying one but not the other) and their conjunction is equivalent to primitivity ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

On Partitioning the Orbitals of a Transitive Permutation Group
, 2002 Let G be a permutation group on a set Ω with a transitive normal subgroup M. Then G acts on the set Orbl(M, Ω) of nontrivial M-orbitals in the natural way, and here we are interested in the case where Orbl(M, Ω) has a partition P such that G acts ...

Multiparticle SUSY quantum mechanics and representations of the permutation group [PDF]
, 2000 The method of multidimensional SUSY quantum mechanics is applied to the investigation of supersymmetrical N -particle systems on a line for the case of separable centre-of-mass motion.
