The reflexive edge strength on some almost regular graphs

Heliyon, 2021
A function f with domain and range are respectively the edge set of graph G and natural number up to ke, and a function f with domain and range are respectively the vertex set of graph G and the even natural number up to 2kv are called a total k-labeling

Further results on edge irregularity strength of graphs

Indonesian Journal of Combinatorics, 2017
A vertex $k$-labelling $\phi:V(G)\longrightarrow \{1,2,\ldots,k\}$ is called irregular $k$-labeling of the graph $G$ if for every two different edges $e$ and $f$, there is $w_{\phi}(e)\neq w_{\phi}(f)$; where the weight of an edge is given by $e=xy\in E ...

On Total Vertex Irregularity Strength of Hexagonal Cluster Graphs

International Journal of Mathematics and Mathematical Sciences, 2021
For a simple graph G with a vertex set VG and an edge set EG, a labeling f:VG∪​EG⟶1,2,⋯,k is called a vertex irregular total k−labeling of G if for any two different vertices x and y in VG we have wtx≠wty where wtx=fx+∑u∈VGfxu.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Total Edge Fibonacci-Like Sequence Irregular Labeling

International Journal of Mathematics and Soft Computing, 2014
In this paper, we are introducing total edge Fibonacci-like sequence irregular labeling. A total edge Fibonacci-like sequence irregular labeling f : V (G) S E(G) → {1, 2, . . . ,K} of a graph G = (V,E) is a labeling of vertices and edges of G in such a way that for any different edges xy and x 0 y 0 their weights f( x ) + f( xy ) + f( y ) and f( x 0 )

Edge irregular reflexive labeling of some tree graphs

Journal of Physics: Conference Series, 2020
Abstract Let G be a connected, simple, and undirected graph with a vertex set V(G) and an edge set E(G). Total k-labeling is a function fe from the edge set to the first ke natural number, and a function fv from the vertex set to the non negative even number up to 2kv, where k ...

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

The total face irregularity strength of some plane graphs

AKCE International Journal of Graphs and Combinatorics, 2020
A face irregular total -labeling of a 2-connected plane graph is a labeling of vertices and edges such that their face-weights are pairwise distinct. The weight of a face under a labeling is the sum of the labels of all vertices and edges surrounding ...
