Inverse problem for Zagreb indices

, 2018
The inverse problem for integer-valued topological indices is about the existence of a graph having its index value equal to a given integer. We solve this problem for the first and second Zagreb indices, and present analogous results also for the ...

Exploratory Analysis of Sustainable Consumption and Production Factors in Services: Insights From Four Case Studies Using Interpretive Structural Modeling

Sustainable Development, EarlyView.
ABSTRACT This study investigates how 14 sustainable consumption and production (SCP) factors interact across four service categories—Mass Service, Professional Service, Service Factory, and Service Shop—using interpretive structural modeling (ISM). ISM enables the identification and hierarchical classification of interdependencies among SCP factors in ...

Computation of Zagreb indices and Zagreb polynomials of Sierpinski graphs

Hacettepe Journal of Mathematics and Statistics, 2020
The Sierpinski fractal or Sierpinski gasket and generalized Sierpinski graphs are objects of great interest in dynamical systems and probability. In this paper, we consider the Sierpinski gasket graph $S_{n}$, the generalized Sierpinski graphs $S(n,C_{3})$ and $S(n,C_{4})$.

Frequency and Severity of Allergic Reactions to Non‐Mandatory Labelled Allergenic Foods—Data From Two Large European Cohorts

Allergy, EarlyView.
In two large European cohorts, 589 reactions to non‐mandatory labelled plant‐based foods were identified with sunflower seed, pine nut, pea and lentil as the most frequent triggers. Reaction severity was not different between mandatory and non‐mandatory labelled allergenic foods. Their frequency and rising trends (e.g., fenugreek, pumpkin seed) support

Some properties of the Zagreb eccentricity indices

Ars Mathematica Contemporanea, 2012
The concept of Zagreb eccentricity (E1 and E2) indices was introduced in the chemical graph theory very recently.In this paper we give some lower and upper bounds on the first Zagreb eccentricity and the second Zagreb eccentricity indices of trees and graphs, and also characterize the extremal graphs.

Improving the Understanding of Late Effects of Testicular Cancer in Adolescent and Young Adult Survivors: TRANSCEND‐XR

Andrology, EarlyView.
ABSTRACT Background Testicular cancer (TC) is the most common malignancy amongst adolescents and young adults (AYAs) aged 15–39 years assigned male at birth. Survivors often experience late effects of treatment and report unmet supportive care needs.

Providing regular and frequent maps of losses and gains of farmland birds based on European monitoring data

Conservation Biology, EarlyView.
Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

ZAGREB CONNECTION INDICES ON POLYOMINO CHAINS AND RANDOM POLYOMINO CHAINS

In this manuscript, we delve into the exploration of the first and second Zagreb connection indices of both polyomino chains and random polyomino chains. Our methodology relies on the utilization of Markov chain theory. Within this framework, the article

Hyper-Zagreb indices of graphs and its applications

, 2021
The first and second Hyper-Zagreb index of a connected graph $G$ is defined by $HM_{1}(G)=\sum_{uv \in E(G)}[d(u)+d(v)]^{2}$ and $HM_{2}(G)=\sum_{uv \in E(G)}[d(u).d(v)]^{2}$. In this paper, the first and second Hyper-Zagreb indices of certain graphs are

Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

Insect Conservation and Diversity, EarlyView.
Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...
