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

On the Number of α-Labeled Graphs
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 ...

ON k-GRACEFUL LABELING OF SOME GRAPHS
Summary: In this paper, it has been shown that the hairy cycle \(C_{n}\odot rK_{1},\) \(n\equiv 3\pmod 4\), the graph obtained by adding pendant edge to each pendant vertex of hairy cycle \(C_{n}\odot 1K_{1}\), \(n\equiv 0\pmod 4\), double graph of path \(P_{n}\) and double graph of comb \(P_{n}\odot 1K_{1}\) are \(k\)-graceful.

Counting and labeling grid related graphs
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.

Graceful Labeling of Spider Graphs With at Most Five Legs
A graceful labeling of a graph G with q edges is an injection f from the vertices of G to the set 0,1,⋯,q such that, when each edge uv is assigned the label fu−fv, the resulting edge labels are distinct.

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
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,

Random Generation Topology Coding Technique in Asymmetric Topology Encryption
The security of traditional public key cryptography algorithms depends on the difficulty of the underlying mathematical problems. Asymmetric topological encryption is a graph-dependent encryption algorithm produced to resist attacks by quantum computers ...
