Minimal Sum Labeling of Graphs [PDF]

open access: yesJournal of Discrete Algorithms, 2018
A graph $G$ is called a sum graph if there is a so-called sum labeling of $G$, i.e. an injective function $\ell: V(G) \rightarrow \mathbb{N}$ such that for every $u,v\in V(G)$ it holds that $uv\in E(G)$ if and only if there exists a vertex $w\in V(G)$ such that $\ell(u)+\ell(v) = \ell(w)$. We say that sum labeling $\ell$ is minimal if there is a vertex

Edge even graceful labelling of some book graphs

open access: yesJournal of Taibah University for Science, 2018
Elsonbaty and Daoud introduced a new type of labelling of a graph G with p vertices and q edges called an edge even graceful labelling if there is a bijection f from the edges of the graph to the set $\{2, 4,\ldots , 2q\}$ such that, when each vertex is ...

Super Edge Bimagic and Trimagic Total Labeling for some Graphs. [PDF]

open access: yesAlfarama Journal of Basic & Applied Sciences
A super edge trimagic total labeling (SETTL) of a graph Γ with α vertices and β edges is a bijection Φ:[V (Γ) ∪ E(Γ)] ⟶{1,2,3,· · · ,α+β} such that for each edge ϑω∈E(Γ), the value of the formula [ Φ(ϑ)+Φ(ω)+Φ(ϑω)] is either Κ_1 or Κ_2 or Κ_3, with the ...

Labelling the axes of graphs … [PDF]

open access: yesNature, 1985
Nature 316, 489 (1985). IN this Scientific Correspondence contribution, the third paragraph should begin: 'The example quoted above requires the observation that if "Radioactivity = 5 x 103 c.p.m." then "5 = (Radioactivity ? l(T3)/c.p.m." or "5 = 103 (Radioactivity/c.p.m.)" or "5 = Radioactivity/(C.p.

Enumeration Of Labelled Graphs [PDF]

open access: yesCanadian Journal of Mathematics, 1956
1. Introduction. The number of connected linear graphs having V vertices labelled 1, … , V and λ (unlabelled) lines is found below. Similar formulas are found for graphs in which slings, lines “in parallel,” or both are allowed and for directed graphs with or without slings or parallel lines.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Characterizations of kites as graceful graphs

open access: yesCubo
We introduce and study an infinite family of graceful graphs, which we call kites. The kites are graphs where a path is joined with a graph "forming" a kite.

On (p, 1)-Total Labelling of Some 1-Planar Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A graph is 1-planar if it can be drawn on the plane so that each edge is crossed by at most one other edge. In this paper, it is proved that the (p, 1)-total labelling number (p ≥ 2) of every 1-planar graph G is at most Δ(G) + 2p − 2 provided that Δ (G) ≥
