Prime labelings on a 3xn grid graph

open access: yesTheory and Applications of Graphs
It is conjectured that the mxn grid graph has a prime labeling for all positive integers m and n. It is known that for any prime p and any integer n such that 1≤n≤p2, there exists a prime labeling on the pxn grid graph Pm x Pn. Also, it is known that the

ON SD-PRIME CORDIAL GRAPHS [PDF]

open access: yesInternational Journal of Pure and Apllied Mathematics, 2016
Let G = (V (G),E(G)) be a simple, finite and undirected graph of order n. Given a bijection f : V (G) → {1,...,n}, we associate 2 integers S = f(u) + f(v) and D = |f(u) − f(v)| with every edge uv in E(G). The labeling f induces an edge labeling f ' : E(G) → {0,1} such that for any edge uv in E(G), f ' (uv) = 1 if gcd(S,D) = 1, and f ' (uv) = 0 ...

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Characterization of rings with planar, toroidal or projective planar prime ideal sum graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
Let R be a commutative ring with unity. The prime ideal sum graph [Formula: see text] of the ring R is the simple undirected graph whose vertex set is the set of all nonzero proper ideals of R and two distinct vertices I and J are adjacent if and only if

Graphs Based on Hoop Algebras

open access: yesMathematics, 2019
In this paper, we investigate the graph structures on hoop algebras. First, by using the quasi-filters and r-prime (one-prime) filters, we construct an implicative graph and show that it is connected and under which conditions it is a star or tree.

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

open access: yesMolecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Prime Graphs of Polynomials and Power Series Over Noncommutative Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences
The prime graph PGR of a ring R is a graph whose vertex set consists of all elements of R. Two elements x,y∈R are adjacent in the graph if and only if xRy=0 or yRx=0.

Structures and applications of graphs arising from congruences over moduli

open access: yesAIMS Mathematics
For any positive integer $ \mathrm{n} $, let $ \mathrm{M_{p}} $ contain the prime numbers less than $ \mathrm{n} $. Assuming $ \mathrm{M_{p}} $ as the set of moduli, we draw a graph with the vertex set $ \{1, 2, 3, \cdots, \mathrm{n}\} $, and an edge ...
