Molecular geometric deep learning

open access: yesCell Reports: Methods, 2023
Summary: Molecular representation learning plays an important role in molecular property prediction. Existing molecular property prediction models rely on the de facto standard of covalent-bond-based molecular graphs for representing molecular topology ...

Vertex-Based Topological Indices of Double and Strong Double Graph of Dutch Windmill Graph

open access: yesJournal of Chemistry, 2021
A measurement of the molecular topology of graphs is known as a topological index, and several physical and chemical properties such as heat formation, boiling point, vaporization, enthalpy, and entropy are used to characterize them.

General Atom-Bond Sum-Connectivity Index of Graphs

open access: yesMathematics, 2023
This paper is concerned with the general atom-bond sum-connectivity index ABSγ, which is a generalization of the recently proposed atom-bond sum-connectivity index, where γ is any real number.

On Bond Incident Degree Indices of Chemical Graphs

open access: yesMathematics, 2022
By swapping out atoms for vertices and bonds for edges, a graph may be used to model any molecular structure. A graph G is considered to be a chemical graph in graph theory if no vertex of G has a degree of 5 or greater.

The Atom-Bond Connectivity Index of Catacondensed Polyomino Graphs

open access: yesDiscrete Dynamics in Nature and Society, 2013
Let G=(V,E) be a graph. The atom-bond connectivity (ABC) index is defined as the sum of weights ((du+dv−2)/dudv)1/2 over all edges uv of G, where du denotes the degree of a vertex u of G.
