Resistance Distance in the Double Corona Based on R-Graph

open access: yesMathematics, 2019
Let G 0 be a connected graph on n vertices and m edges. The R-graph R ( G 0 ) of G 0 is a graph obtained from G 0 by adding a new vertex corresponding to each edge of G 0 and by joining each new vertex to the end

Spanning trees in complete bipartite graphs and resistance distance in nearly complete bipartite graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2019
Using the theory of electrical network, we first obtain a simple formula for the number of spanning trees of a complete bipartite graph containing a certain matching or a certain tree.

The Extremal Cacti on Multiplicative Degree-Kirchhoff Index

open access: yesMathematics, 2019
For a graph G, the resistance distance r G ( x , y ) is defined to be the effective resistance between vertices x and y, the multiplicative degree-Kirchhoff index R ∗ ( G ) = ∑ { x , y } ⊂ V ( G ) d G ( x ) d G

Formulation of tunneling resistance between neighboring carbon nanotubes in polymer nanocomposites

open access: yesEngineering Science and Technology, an International Journal, 2021
We aim to express the tunneling resistance in polymer nanocomposites by carbon nanotube (CNT) concentration, interphase depth, CNT curliness, tunneling distance, interfacial tension, network portion and CNT size.

Genetic mapping, synteny, and physical location of two loci for Fusarium oxysporum f. sp. tracheiphilum race 4 resistance in cowpea [Vignaunguiculata (L.) Walp]. [PDF]

open access: yes, 2013
Fusarium wilt is a vascular disease caused by the fungus Fusariumoxysporum f.sp. tracheiphilum (Fot) in cowpea [Vignaunguiculata (L.) Walp]. In this study, we mapped loci conferring resistance to Fot race 4 in three cowpea RIL populations: IT93K-503-1 ...

Metrics and spectral triples for Dirichlet and resistance forms [PDF]

open access: yes, 2013
The article deals with intrinsic metrics, Dirac operators and spectral triples induced by regular Dirichlet and resistance forms. We show, in particular, that if a local resistance form is given and the space is compact in resistance metric, then the ...

Further Results on the Resistance-Harary Index of Unicyclic Graphs

open access: yesMathematics, 2019
The Resistance-Harary index of a connected graph G is defined as R H ( G ) = ∑ { u , v } ⊆ V ( G ) 1 r ( u , v ) , where r ( u , v ) is the resistance distance between vertices u and v in G.
