C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

On intuitionistic fuzzy characteristic and Frattini subgroups [PDF]

open access: yesNotes on IFS
This paper presents intuitionistic fuzzy characteristic subgroups and discusses some of its properties. It is established that an intuitionistic fuzzy subgroup of an intuitionistic fuzzy group is characteristic provided its cuts are characteristic ...

Frattini embeddings of normal subgroups [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
If N is a normal subgroup of the finite group G, there is a split extension X of an elementary abelian group by G such that N ⊴ X N \trianglelefteq X and N ∩ Φ ( G ) = Φ ( X ) N \cap \Phi (G) = \Phi (X) .

Lesion Location and Functional Connections Reveal Cognitive Impairment Networks in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.

Groups with Few Normalizer Subgroups

open access: yesIrish Mathematical Society Bulletin, 2005
The behaviour of normalizer subgroups of a group has often a strong influence on the structure of the group it- self. In this paper groups with finitely many normalizers of subgroups with a given propertyare investigated, for vari- ous relevant choices of the property ´.

The Impact of Tilburg Frailty on Poststroke Fatigue in First‐Ever Stroke Patients: A Cross‐Sectional Study With Unified Measurement Tools and Improved Statistics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Poststroke fatigue (PSF) and frailty share substantial overlap in their manifestations, yet previous research has yielded conflicting results due to the use of heterogeneous frailty assessment tools. Objective To evaluate the independent impact of frailty on PSF using a unified measurement system (Tilburg Frailty Indicator, TFI ...

The Commutator of Two Fuzzy Subsets

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
In this paper we introduce the idea of the commutator of two fuzzy subsets of a group and study the concept of the commutator of two fuzzy subsets of a group .We introduce and study some of its properties .
