On the difference between the Szeged and Wiener index [PDF]

open access: yesApplied Mathematics and Computation, 2016
We prove a conjecture of Nadjafi-Arani, Khodashenas and Ashrafi on the difference between the Szeged and Wiener index of a graph. Namely, if $G$ is a 2-connected non-complete graph on $n$ vertices, then $Sz(G)-W(G)\ge 2n-6$.

On the relationship between variable Wiener index and variable Szeged index [PDF]

open access: yesApplied 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 ...

Prescription of Rifampicin for Staphylococcus aureus Infections Increased the Incidence of Corynebacterium striatum with Decreased Susceptibility to Rifampicin in a Hungarian Clinical Center

open access: yesPathogens, 2023
Several reports have suggested a role for Corynebacterium striatum as an opportunistic pathogen. The authors have conducted a retrospective study at the Clinical Center of the University of Szeged, Hungary, between 2012 and 2021 that revealed ...

Urban-rural air humidity differences in Szeged, Hungary [PDF]

open access: yes, 1999
Measurements of vapour pressure, taken four times a day over a 3-year period, were used to investigate the urban influence on diurnal and annual patterns of vapour pressure differences. The examined settlement is a medium-sized city without significant

On vertex PI index of certain triangular tessellation networks

open access: yesMain 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

open access: yesBeilstein 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

open access: yesIEEE 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
