Some More Results on Reciprocal Degree Distance Index and ℱ‐Sum Graphs

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
A chemical invariant of graphical structure Z is a unique value characteristic that remains unchanged under graph automorphisms. In the study of QSAR/QSPR, like many other chemical invariants, reciprocal degree distance has played a significant role to estimate the bioactivity of several compounds in chemistry.

Bounds on Szeged and PI Indexes in terms of Second Zagreb Index [PDF]

open access: yes, 2012
In this short note, we studied the vertex version and the edge version of the Szeged index and the PI index and obtained bounds for these indices in terms of the Second Zagreb index.

Ordering Acyclic Connected Structures of Trees Having Greatest Degree‐Based Invariants

open access: yesComplexity, Volume 2022, Issue 1, 2022., 2022
Being building block of data sciences, link prediction plays a vital role in revealing the hidden mechanisms that lead the networking dynamics. Since many techniques depending in vertex similarity and edge features were put forward to rule out many well‐known link prediction challenges, many problems are still there just because of unique formulation ...

Two Complex Graph Operations and their Exact Formulations on Topological Properties

open access: yesComplexity, 2022
Graph operations are utilized for developing complicated graph structures from basic graphs, and these basic graphs can help to understand the properties of complex networks. While on the other side, the topological descriptor is known as a numeric value

On hyper-Zagreb index conditions for hamiltonicity of graphs [PDF]

open access: yes, 2022
summary:During the last decade, several research groups have published results on sufficient conditions for the hamiltonicity of graphs by using some topological indices. We mainly study hyper-Zagreb index and some hamiltonian properties.

The multiplicative reformulated first Zagreb index of some graph operations

open access: yesMalaya Journal of Matematik, 2020
In this paper, the multiplicative reformulated first Zagreb index is presented and the sharp upper bound for the multiplicative reformulated first Zagreb index of various graph operations for example, join, composition, cartesian and corona product of graphs are derived.

A note on multiplicative sum Zagreb index [PDF]

open access: yes, 2020
For a nontrivial (molecular) graph G, its multiplicative sum Zagreb index, denoted by π * 1 (G), is defined as the product of the sum is the degree of vertex u.

Optimal Design of Elastic Plates: Hybrid Numerical Method Based on Homogenization and Shape Derivative

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 17, Page 17793-17815, 30 November 2026.
ABSTRACT This paper focuses on optimal design problems in the context of the Kirchhoff‐Love model for pure bending of a thin, solid, symmetric plate under a transverse load. The objective is to simultaneously determine the optimal outer shape of the domain and the distribution of two isotropic materials within the domain in order to minimize compliance.

An Evaluation Framework for Post‐Trained Bookkeeping Language Models

open access: yesIntelligent Systems in Accounting, Finance and Management, Volume 33, Issue 3, September 2026.
ABSTRACT Supervised fine‐tuning (SFT) enables large language models (LLMs) to acquire domain‐specific knowledge, yet the resulting trade‐off between specialization and general capability preservation remains poorly understood. This paper investigates this trade‐off systematically by fine‐tuning three open‐source LLMs on double‐entry bookkeeping posting

Forward Contract Decomposition‐Based Optimal Residential Pricing Strategy for Retailer Under the Forward and Spot Market Trading

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
An optimal contract decomposition method considering monthly contract disintegration deviation minimisation and its impact on retail pricing strategy, comparing typical decomposition approaches, is investigated in this paper. The TOU price is settled by solving a multi‐objective optimisation problem considering the retailer's expected profit ...
