Quasi-Tree Graphs With Extremal General Multiplicative Zagreb Indices
IEEE Access, 2020 Zagreb indices and their modified versions of a molecular graph are important molecular descriptors which can be applied in characterizing the structural properties of organic compounds from different aspects. In this article, by exploring the structures

ZAGREB INDICES OF A NEW SUM OF GRAPHS
Ural Mathematical Journal, 2023 The first and second Zagreb indices, since its inception have been subjected to an extensive research in the physio- chemical analysis of compounds. In [6] Hanyuan Deng et.al computed the first and second Zagreb indices of four new operations on a graph ...

Advanced Electronic Materials, EarlyView.A fully coupled FEM–HH model shows that ideally capacitive microelectrodes can achieve lower charge‐density thresholds than Faradaic contacts under current‐controlled stimulation. The advantage stems from the dynamics of surface current density on capacitive interfaces, which redirects current beneath adherent neurons.

Introducing New Exponential Zagreb Indices for Graphs
Journal of Mathematics, 2021 New graph invariants, named exponential Zagreb indices, are introduced for more than one type of Zagreb index. After that, in terms of exponential Zagreb indices, lists on equality results over special graphs are presented as well as some new bounds on ...

Novel Degree-Based Topological Descriptors of Fenofibrate Using M-Polynomial
Journal of Mathematics, 2023 Chemical graph theory is currently expanding the use of topological indices to numerically encode chemical structure. The prediction of the characteristics provided by the chemical structure of the molecule is a key feature of these topological indices ...

British Journal of Clinical Pharmacology, EarlyView.Aims Hypertension is a leading modifiable risk factor for cardiovascular mortality worldwide. This study aimed to evaluate 25‐year trends in antihypertensive agent (AHA) utilization in Croatia between 2000 and 2024. Methods We conducted a national, population‐based analysis using IMS and IQVIA pharmaceutical databases.

Topological Evaluation of Four Para-Line Graphs Absolute Pentacene Graphs Using Topological Indices
International Journal of Analysis and Applications, 2023 A real-number to molecular structure mapping is a topological index. It is a graph invariant method for describing physico-chemical properties of molecular structures specific substances. In that article, We examined pentacene’s chemical composition. The

On Zagreb Eccentricity Indices
Croatica Chemica Acta, 2011 Zagreb eccentricity indices were proposed analogously to Zagreb indices already known and used for almost forty years. For a connected graph, the first Zagreb eccentricity index is defined as the sum of the squares of the eccentricities of the vertices, and the second Zagreb eccentricity index is defined as the sum of the products of the eccentricities
