On Distance-Based Topological Descriptors of Chemical Interconnection Networks
Journal of Mathematics, 2021 Structure-based topological descriptors of chemical networks enable us the prediction of physico-chemical properties and the bioactivities of compounds through QSAR/QSPR methods.

On the relationship between variable Wiener index and variable Szeged index [PDF]
Applied Mathematics and Computation, 2022 We resolve two conjectures of Hriňáková, Knor and Škrekovski (2019) concerning the relationship between the variable Wiener index and variable Szeged index for a connected, non-complete graph, one of which would imply the other. The strong conjecture is that for any such graph there is a critical exponent in $(0,1]$, below which the variable Wiener ...

HYDROLOGICAL DROUGHT ASSESSMENT OF THE TISZA RIVER
Zbornik Radova: Geografski institut "Jovan Cvijić", 2020 Drought is a natural phenomenon that occurs when the availability of water is significantly below the normal levels during a shorter or longer period of time and cannot meet the necessary demand.

On vertex PI index of certain triangular tessellation networks
Main Group Metal Chemistry, 2021 The Wiener index, due to its many applications is considered to be one of very important distance-based index. But the Padmaker-Ivan (PI) index is kind of the only distance related index linked to parallelism of edges.

Topological edge properties of C60+12n fullerenes
Beilstein Journal of Nanotechnology, 2013 A molecular graph M is a simple graph in which atoms and chemical bonds are the vertices and edges of M, respectively. The molecular graph M is called a fullerene graph, if M is the molecular graph of a fullerene molecule.

The Topological Aspects of Phthalocyanines and Porphyrins Dendrimers
IEEE Access, 2020 Topological descriptors are the numerical quantities of a graph that characterize various structural properties of it. In environmental sciences, pharmacy and in mathematical chemistry such descriptors are used for the quantitative structure-activity and

Weighted Szeged indices of some graph operations [PDF]
Transactions on Combinatorics, 2016 In this paper, the weighted Szeged indices of Cartesian product and Corona product of twoconnected graphs are obtained. Using the results obtained here, the weighted Szeged indices ofthe hypercube of dimension n, Hamming graph, C4 nanotubes, nanotorus ...
