On the spectra of reduced distance matrix of dendrimers [PDF]
Transactions on Combinatorics, 2013 Let G be a simple connected graph and {v_1,v_2,... , v_k} be the set of pendent (vertices of degree one) vertices of G. The reduced distance matrix of G is an square matrix whose (i,j)-entry is the topological distance between v_i and v_j of G.

Gutman Index and Detour Gutman Index of Pseudo-Regular Graphs
Journal of Applied Mathematics, 2017 The Gutman index of a connected graph G is defined as Gut(G)=∑u≠vd(u)d(v)d(u,v), where d(u) and d(v) are the degree of the vertices u and v and d(u,v) is the distance between vertices u and v.

The last subconstituent of a bipartite Q-polynomial distance-regular graph [PDF]
, 2003 Let Γ denote a bipartite distance-regular graph with diameter D≥3. Fix any vertex x and let ΓD=ΓD(x) denote the set of vertices at distance D from x. Let ΓD2=ΓD2(x) denote the graph with vertex set ΓD, and edge set consisting of all pairs of vertices in ...

On the Multiplicities of the Primitive Idempotents of a Q-Polynomial Distance-regular Graph [PDF]
, 2002 Ito, Tanabe and Terwilliger recently introduced the notion of a tridiagonal pair. We apply their results to distance-regular graphs and obtain the following theorem.Theorem Let Γ denote a distance-regular graph with diameter D≥ 3.

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 Local Structure of a Bipartite Distance-regular Graph [PDF]
, 1999 In this paper, we consider a bipartite distance-regular graph Γ= (X, E) with diameter d≥ 3. We investigate the local structure ofΓ , focusing on those vertices with distance at most 2 from a given vertex x.

Advanced Engineering Materials, EarlyView.A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.
