Extremal Properties of the Zagreb Eccentricity Indices [PDF]

, 2012
We give sharp lower bounds for the Zagreb eccentricity indices of connected graphs with fixed numbers of vertices and edges, sharp lower and upper bounds for the Zagreb eccentricity indices of trees with fixed number of pendant vertices, sharp upper ...

Reformulated Zagreb indices of thorny graphs and algorithms

Mathematics in Applied Sciences and Engineering
Molecular descriptors (graph indices) numerically describe the topologies of the chemicals. Graph indices are used to estimate certain properties of molecules. In this paper, reformulated first/second Zagreb indices for the thorny graph of any graph are

On a Linear Combination of Zagreb Indices

Discrete Mathematics Letters, 2023
Summary: The modified first Zagreb connection index of a triangle-free and quadrangle-free graph \(G\) is equal to \(2M_2(G)-M_1(G)\), where \(M_2(G)\) and \(M_1(G)\) are the well-known second and first Zagreb indices of \(G\), respectively. This paper involves the study of the linear combination \(2M_2(G)-M_1(G)\) of \(M_2(G)\) and \(M_1(G)\) when \(G\

On Zagreb Indices as Complexity Indices

Croatica chemica acta, 2000
Two original Zagreb indices, denoted M1 and M2, and introduced in 1972, were symmetry-modified by summing up only degrees (SMM1) or edge-weights (SMM2) of symmetry nonequivalent vertices or edges of graphs. Their dependence on the structural features and symmetry of molecular graphs is studied. They were also compared to eight other complexity indices (

Trends in 25 years of antihypertensive agent utilization in Croatia – an alert for scientific community and healthcare providers

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.

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-Type Indices of R-Vertex Join and R-Edge Join of Graphs

Journal of Chemistry, 2020
There are various methods available which are used to search large chemical databases and to predict the physicochemical properties of molecular structures. Using molecular descriptors for this purpose is the simplest of these methods. The Zagreb indices

Economic evaluations of antiobesity medications: A systematic literature review

British Journal of Clinical Pharmacology, EarlyView.
The global prevalence of obesity is rising rapidly. With several antiobesity medications approved and many more in development, understanding their economic value is increasingly important. This study reviews full economic evaluations of approved antiobesity medications to assess cost‐effectiveness and inform reimbursement and access decisions.
