An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Totally -closed finite groups with trivial Fitting subgroup

Bulletin of Mathematical Sciences
A finite permutation group [Formula: see text] is called [Formula: see text]-closed if [Formula: see text] is the largest subgroup of [Formula: see text] which leaves invariant each of the [Formula: see text]-orbits for the induced action on [Formula ...

Fault Diagnosis Method of Planetary Gearboxes Based on LMD Permutation Entropy and BP Neural Network

Jixie chuandong, 2022
In view of the problems of poor discrimination of fault feature vectors extracted in the process of fault diagnosis of planetary gearboxes and insufficient diagnosis success rate, a method based on Local Mean Decomposition（LMD） permutation entropy and BP

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 \

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Commutators of cycles in permutation groups

Ars Mathematica Contemporanea, 2015
We prove that for  n  ≥ 5 , every element of the alternating group  A n  is a commutator of two cycles of  A n . Moreover we prove that for  n  ≥ 2 , a  (2 n  + 1) -cycle of the permutation group  S 2 n  + 1  is a commutator of a  p -cycle and a  q -cycle of  S 2 n  + 1  if and only if the following three ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

PERMUTATION GROUPS WITH BOUNDED MOVEMENT ATTAINING THE BOUNDS FOR ODD PRIMES [PDF]

Journal of Sciences, Islamic Republic of Iran, 1998
Let G be a transitive permutation group on a set ? and let m be a positive integer. If no element of G moves any subset of ? by more than m points, then |? | [2mp I (p-1)] wherep is the least odd primedividing |G |. When the bound is attained, we show

Symmetry classes of polynomials associated with the ‎direct ‎product of permutation groups [PDF]

International Journal of Group Theory, 2014
Let $G_{i} $ be a subgroup of $ S_{m_{i}} , 1 leq i leq k$. Suppose $chi_{i}$ is an irreducible complex character of $G_{i}$. We consider $ G_{1}times cdots times G_{k} $ as subgroup of $ S_{m} $, where $ m=m_{1}+cdots +m_{k} $.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.
