On the strong beta-number of galaxies with three and four components

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The beta-number of a graph is the smallest positive integer for which there exists an injective function such that each is labeled and the resulting set of edge labels is for some positive integer . The beta-number of is if there exists no such integer .

A Synergistic Inhibitor Development Strategy Against Human UDP‐Galactose‐4‐Epimerase

open access: yesAngewandte Chemie International Edition, EarlyView.
The epimerase GalE is crucial for the biosynthesis of cancer‐relevant O‐GalNAc glycans. Here, we employ orthogonal, structurally enabled small molecule fragment screens to yield both covalent and non‐covalent inhibitors against GalE within no more than 22 elaborated compounds.

On the Number of α-Labeled Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
When a graceful labeling of a bipartite graph places the smaller labels in one of the stable sets of the graph, it becomes an α-labeling. This is the most restrictive type of difference-vertex labeling and it is located at the very core of this research ...

Graceful Labeling For bipartite graceful Graphs and related Graphs

open access: yes, 2020
The concept of graceful labels was proposed by Rosa, scholars began to study graceful labels of various graphs and obtained relevant results.Let the graph is a bipartite graceful graph, we have proved some graphs are graceful labeling in this paper.

Time‐Resolved Native Mass Spectrometry Reveals Reversible Light‐Driven Oligomerization of Arabidopsis Cryptochrome 1 and Its Antagonism by BIC1

open access: yesAngewandte Chemie International Edition, EarlyView.
Time‐resolved native mass spectrometry uncovers the blue‐light‐dependent kinetic mechanism of Arabidopsis CRY1 oligomerization, proceeding sequentially from monomers to dimers and tetramers. ATP promotes assembly, whereas BIC1 actively blocks and disassembles tetramers independent of light, providing mechanistic insight into the regulation of ...

Counting and labeling grid related graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2019
In this work we explore some graphs associated with the grid Pm × Pn. A fence is any subgraph of the grid obtained by deleting any feasible number of edges from some or all the copies of Pm.

Edge-Graceful Labelings of Connected Graphs

open access: yesElectronic Notes in Discrete Mathematics, 2016
Abstract Let G be a connected edge-graceful ( p , q ) -graph with q = k p + r , where k is an integer and 0 ≤ r p . In this paper, we prove that every edge-graceful labeling f of G induces [ ( k + 1 ) ! ] r [ k ! ] p − r number of edge-graceful labelings of G.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Cytokine Pathways Driving Diverse Tissue Pathologies in Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Rheumatoid arthritis (RA) is a complex systemic disorder characterized primarily by articular inflammation and destruction with associated functional loss and reduced quality of life. RA is also associated with extra‐articular disease, such as that of the lung, with potentially devastating clinical consequences. The critical importance of comorbidities,

Why do people choose to enter and exit the teaching profession? An interdisciplinary quantitative synthesis

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Many nations experience recurring shortages of teachers in particular subjects, prompting concerns that pupils' education is suffering as a result. Researchers have responded by generating a sizable literature on the reasons for which people enter and exit the teaching profession.
