Ordering graphs with large eccentricity-based topological indices

Journal of Inequalities and Applications, 2021
For a connected graph, the first Zagreb eccentricity index ξ 1 $\xi _{1}$ is defined as the sum of the squares of the eccentricities of all vertices, and the second Zagreb eccentricity index ξ 2 $\xi _{2}$ is defined as the sum of the products of the ...

Extremal unicyclic and bicyclic graphs with respect to the -index

AKCE International Journal of Graphs and Combinatorics, 2017
In the study of structure-dependency of the total -electron energy in 1972, it was shown that this energy depends on the degree based sum and , where is the degree of a vertex of under consideration molecular graph .

Chemical Recycling as a Tool for Enabling a Second Life for Polyesters

SusMat, EarlyView.
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

On Sombor index and graph energy of some chemically important graphs

Examples and Counterexamples
Sombor index of a graph G=(V(G),E(G)) is provided by the expression ∑uv∈E(G)du2+dv2, where dx is the degree of the vertex x∈V(G). The energy of a graph is the quantity given by the total of the absolute values of its adjacency matrix’s eigenvalues.

The Hosoya index and the Merrifield-Simmons index of some graphs [PDF]

Transactions on Combinatorics, 2012
The Hosoya index and the Merrifield-Simmons index are two types of graph invariants used in mathematical chemistry. In this paper, we give some formulas for computed these indices for some classes of corona product and link of two graphs. Furthermore, we

On Mostar and Edge Mostar Indices of Graphs

Journal of Mathematics, 2021
Let G be a graph with edge set EG and e=uv∈EG. Define nue,G and mue,G to be the number of vertices of G closer to u than to v and the number of edges of G closer to u than to v, respectively. The numbers nve,G and mve,G can be defined in an analogous way.

Mixed Super‐Circles

Computer Graphics Forum, EarlyView.
Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

UrbanClipAtlas: A Visual Analytics Framework for Event and Scene Retrieval in Urban Videos

Computer Graphics Forum, EarlyView.
Abstract Extracting actionable insights from long‐duration urban videos is often labor‐intensive: analysts must manually sift through raw footage to pinpoint target events or uncover broader behavioral trends. In this work, we present UrbanClipAtlas, a visual analytics system for exploring long urban videos recorded at street intersections ...

FlowGS: Controlling Information Flow for Graph‐Based Interaction in 3D Gaussian Splatting

Computer Graphics Forum, EarlyView.
Abstract 3D Gaussian Splatting (3DGS) has recently enabled real‐time, high‐quality novel view synthesis. However, its formulation treats each Gaussian independently, lacking explicit information exchange between neighboring elements and limiting its ability to capture local structure.
