Inverse problem for the forgotten and the hyper zagreb indices of trees

open access: yes, 2022
Let G = (E(G), V (G)) be a (molecular) graph with vertex set V (G) and edge set E(G). The forgotten Zagreb index and the hyper Zagreb index of G are defined by F(G) = Sigma(u is an element of V) (G) d(u)(3) and HM(G) = Sigma(uv is an element of 2E)(G) (d(

Topological Characterization of Carbon Graphite and Crystal Cubic Carbon Structures

open access: yesMolecules, 2017
Graph theory is used for modeling, designing, analysis and understanding chemical structures or chemical networks and their properties. The molecular graph is a graph consisting of atoms called vertices and the chemical bond between atoms called edges ...

Computing zagreb indices and zagreb polynomials of fullerene, butterfly and benes networks

open access: yes, 2019
A topological index is a numerical parameter of a graph which characterizes some of the topological properties of the graph. The concepts of hyper-Zagreb index, first multiple Zagreb index, second multiple Zagreb index and relatedly the Zagreb ...

Effect of Interleukin‐6 Inhibitors on Rheumatoid Arthritis Pain: Overview of Evidence and Mechanistic Pathways

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 2, April 2026.
This review synthesizes current mechanistic and clinical evidence on IL‐6 inhibitors, particularly sarilumab and tocilizumab, concerning their effect on pain in RA. ABSTRACT Rheumatoid arthritis (RA) is an autoimmune systemic disease in which pain remains a major and often refractory symptom even after clinical remission of the disease.

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

open access: yesPediatric Blood &Cancer, Volume 73, Issue 3, March 2026.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

On multiplicative degree based topological indices for planar octahedron networks

open access: yesMain Group Metal Chemistry, 2020
Chemical graph theory is a branch of graph theory in which a chemical compound is presented with a simple graph called a molecular graph. There are atomic bonds in the chemistry of the chemical atomic graph and edges. The graph is connected when there is

Addressing Gaps in Butterfly Population Monitoring to Catalyze Global Insect Conservation

open access: yesConservation Letters, Volume 19, Issue 2, March/April 2026.
ABSTRACT The conservation community sorely lacks a global indicator of change in insect populations. Given widespread insect declines, addressing this gap is key for conservation and policy targets. We suggest that butterfly monitoring programs can serve as the foundation for an effective global network of insect monitoring.
