Congruences on orthodox semigroups with associate subgroups [PDF]

Glasgow Mathematical Journal, 1996
If Sis a regular semigroup then an inverse transversal of S is an inverse subsemigroup T with the property that |T ∩ V(x)| = 1 for every x ∈ S where V(x) denotes the set of inverses of x ∈ S. In a previous publication [1] we considered the similar concept of a subsemigroup T of S such that |T ∩ A(x)| = 1 for every x ∩ S where A(x) = {y∈ S;xyx = x ...

On Closed Subgroups Associated with Involutions

Real Analysis Exchange, 2008
AbstractGiven an involution fon (0;1);we prove that the set C(f) := f>0 : fis an involutiong is a closed multiplicative subgroup of (0;1) andtherefore C(f) is f1g, (0;1) or Z = f n : n2 Zg for some >0, 6= 1.Moreover, we provide examples of involutions possessing each one of theabove types as the set C(f) and prove that the unique involutions fsuchthat

New insights on the pathogenesis of paraganglioma and pheochromocytoma [version 1; referees: 2 approved]

F1000Research, 2018
Pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare chromaffin cell tumors (PPGLs) that at times raise significant challenges in clinical recognition, diagnosis, and therapy and when undiagnosed could associate with severe morbidity.

A complete compendium of crystal structures for the human SEPT3 subgroup reveals functional plasticity at a specific septin interface

IUCrJ, 2020
Human septins 3, 9 and 12 are the only members of a specific subgroup of septins that display several unusual features, including the absence of a C-terminal coiled coil.

Characterization of the USDA Cucurbita pepo, C. moschata, and C. maxima germplasm collections

Frontiers in Plant Science, 2023
The Cucurbita genus is home to a number of economically and culturally important species. We present the analysis of genotype data generated through genotyping-by-sequencing of the USDA germplasm collections of Cucurbita pepo, C. moschata, and C. maxima.

Elucidation of predictors of disease progression in patients with relapsing polychondritis at the onset: potential impact on patient monitoring

BMC Rheumatology, 2020
Background In patients with relapsing polychondritis (RP), organ involvement developed in those with progressive and/or long disease courses. For their management, elucidation of a subgroup suggesting disease progression is awaited. Methods We previously

Association between Usual Dietary Intake of Food Groups and DNA Methylation and Effect Modification by Metabotype in the KORA FF4 Cohort

Life, 2022
Associations between diet and DNA methylation may vary among subjects with different metabolic states, which can be captured by clustering populations in metabolically homogenous subgroups, called metabotypes.

Genetic population structure analysis in New Hampshire reveals Eastern European ancestry. [PDF]

PLoS ONE, 2009
Genetic structure due to ancestry has been well documented among many divergent human populations. However, the ability to associate ancestry with genetic substructure without using supervised clustering has not been explored in more presumably ...

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

SYMMETRY CLASSES OF TENSORS ASSOCIATED WITH YOUNG SUBGROUPS

Asian-European Journal of Mathematics, 2011
The aim of this article is to study symmetry classes of tensors associated with Young subgroups of the symmetric group. We will discuss the dimension as well as *-bases of these types of symmetry classes.
