Journal of Chemistry, Volume 2026, Issue 1, 2026.Topological indices are crucial in modeling of molecular structures of graphs and are also useful in correlation with physicochemical properties. In this paper, we propose the Euler Sombor coindex and Gourava Sombor coindex, and we derive bounds by using some graph invariants of a graph such as the degree of a vertex, the order, and the size of a graph.

Journal of Mathematics, Volume 2026, Issue 1, 2026.In this article, the first eccentricity connectivity coindex is introduced as ECI¯G=∑uv∉EGε2u+ε2v, in which ε(u) denotes the eccentricity of the vertex u in the simple connected graph G. Then, the exact expressions are obtained for the first eccentricity connectivity coindex of some graph products.

Intelligent Systems in Accounting, Finance and Management, Volume 32, Issue 3, September 2025.ABSTRACT The development of an in‐house accounting bot—an artificial intelligence (AI) assistant capable of generating internally structured bookkeeping double‐entry posting schemes—is explored in this paper. The processes of curating a suitable dataset, selecting, and fine‐tuning a seven‐billion‐parameter language model, categorized as a small ...

Between deep comradeship and nationalism: The social dynamics of solidarity on the battlefield
Nations and Nationalism, Volume 31, Issue 1, Page 47-63, January 2025.Abstract This article explores the social mechanisms that facilitate the transformation of micro‐level bonds into coherent nationalist narratives of solidarity. The aim is to explain the paradox: while the armed forces are highly nationalist institutions, most ordinary combatants detest nationalist rhetoric on the battlefield. Drawing on the interviews

Reformulated Zagreb Indices of Trees [PDF]
Zagreb indices were reformulated in terms of the edge degrees instead of the vertex degrees. For a graph $G$, the first and second reformulated Zagreb indices are defined respectively as:$$EM_1(G)=\sum_{\varepsilon\in E(G)}d^2(\varepsilon), EM_2(G)=
