Congruence and non-congruence subgroups of the (2,3,7)-group [PDF]

, 2006
Let [DELTA] denote the (2,3,7)-group. We establish an upper bound for the number of congruence subgroups of index n and a lower bound for the total number of subgroups of index n.

Elementary Abelian 5-Subgroups of the Monster

Journal of Algebra, 1994
The aim of this paper is to give a complete list of the conjugacy classes of elementary abelian 5-subgroups of the Monster simple group. There are four of order \(5^ 4\) and eight of order \(5^ 3\), as well as the well- known seven of order \(5^ 2\) -- see for example the reviewer's paper [J. Aust. Math. Soc., Ser. A 44, No.

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

A Geometric Study of Commutator Subgroups [PDF]

, 2009
Let G be a group and G' its commutator subgroup. Commutator length (cl) and stable commutator length (scl) are naturally defined concepts for elements of G'. We study cl and scl for two classes of groups.

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 ...

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

ELEMENTARY AMENABLE SUBGROUPS OF R. THOMPSON'S GROUP F [PDF]

International Journal of Algebra and Computation, 2005
We study the subgroups of R. J. Thompson's group F and PLo(I), the group of orientation preserving, piecewise linear self homeomorphisms of [0, 1]. We exhibit, for each non-limit ordinal α ≤ ω2 + 1, an elementary amenable group of elementary class α (under Chou's stratification of elementary amenable groups) that is a subgroup of F and thus of PLo(I).

Leadership and Literacy Processes in School Improvement Creating and Supporting a Community of Success: A Case Study Examining the Principal's Role in the Reconstitution of a Campus to Transform Literacy and Learning [PDF]

Journal of Systemics, Cybernetics and Informatics, 2018
Any number of school districts in the U.S. are having to improve schools that have been underperforming by state and federal measures. Research has indicated that one of the ways to effectively improve school performance is by reconstituting the school ...
