Laplacian spectra and invariants of graphs
Discrete Mathematics, 2002 Let \(b(G)=(n-1)/(1/\lambda_2 + 1/\lambda_3 + \dots + 1/\lambda_n)\) be the harmonic mean of positive Laplacian eigenvalues \(\lambda_2, \lambda_3, \dots, \lambda_n\) of a connected graph \(G\) with \(n\) vertices. The author gives bounds for the minimal edge-density in edge-cuts, edge-connectivity, isoperimetric number, average distance, average ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

The distance Seidel matrix of connected graphs
AKCE International Journal of Graphs and CombinatoricsFor a connected graph G, we present the concept of a new graph matrix related to its distance and Seidel matrix, called distance Seidel matrix [Formula: see text]. Suppose that the eigenvalues of [Formula: see text] be [Formula: see text] In this article,

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science
Advanced Engineering Materials, EarlyView.We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.
