On the Extremal Weighted Mostar Index of Bicyclic Graphs

Axioms
Let G be a simple connected graph with edge set E(G) and vertex set V(G). The weighted Mostar index of a graph G is defined as w+Mo(G)=∑e=uv∈E(G)(dG(u)+dG(v))|nu(e)−nv(e)|, where nu(e) denotes the number of vertices closer to u than to v for an edge uv ...

Reliable Apparent Permeability Prediction Through Benchmarking, Stability, Uncertainty Quantification, and Explainable Machine Learning

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 8, August 2026.
ABSTRACT Apparent permeability (Papp$$ {P}_{app} $$) of a drug molecule serves as a principal indicator of drug absorption for pharmacokinetic modeling, and accurate prediction of Papp$$ {P}_{app} $$ values using machine learning would avoid time‐consuming and expensive In Vitro experiments.

Computing the determinant of a signed graph

Open Mathematics
A signed graph is a simple graph in which every edge has a positive or negative sign. In this article, we employ several algebraic techniques to compute the determinant of a signed graph in terms of the spectrum of a vertex-deleted subgraph.
