We call (_ ij ) the resistive inverse of (R ij ). ... This uniquely determines the matrix (R ij ) of effective resistances, defined such that if a potential of 1 V is applied across nodes i and j, a current of 1ÂR ij will flow. ...

Moreover, relations between the inverse Perron values and resistance distance of a connected graph are presented. ... By using the inverse Perron values, we give an estimation of the edge connectivity of a $2$-design, and determine the explicit edge connectivity of a symmetric design. ... Since e(G) is a positive integer, we get e(G) = k = r. the electronic journal of combinatorics 25(4) (2018), #P4.28 Inverse Perron values and resistance distance of graphs For a vertex i of a connected ...doi:10.37236/7410 fatcat:7wn4wrbel5fgzjnaurquj7qmoi
The importance of biostatistical and mathematical models regarding antimicrobial resistance (AMR) cannot be overstated. ... Models help define the system being observed in order to study the influences of various components upon that system and to predict outcomes. ...

A proof of an algorithm for finding related descriptions (effective resistance matrix and resistive inverse matrix) is given. ... resistive inverses. ...
We give several formulas for the tau constant, and show how it changes under graph operations including deletion of an edge, contraction of an edge, and union of graphs along one or two points. ... We prove Baker and Rumely's lower bound conjecture on the tau constant for several classes of metrized graphs. ... Then the effective resistance in Γ between p and q is equal to the effective resistance in β between p and q. These are illustrated by the first two graphs in Figure 1 . ...doi:10.37236/568 fatcat:ao55vxnq55e4pefluql74sc3ma

These formulas generalize the determinant formulas given by Curtis, Ingerman, and Morrow, and by Fomin, for parallel pairings. ... In particular, for "tripartite" pairings of the nodes, the probability can be computed as a Pfaffian in the entries of the Dirichlet-to-Neumann matrix (discrete Hilbert transform) of the graph. ... The effective resistance and current response can be expressed in terms of the edge conductances via matrix linear algebra, and these formulas can be still be used formally when the edge conductances are ...doi:10.37236/201 fatcat:2mkrxxndnnfu5iehxo37gbr22m
Recently, in Refs. jsj and res2, calculation of effective resistances on distance-regular networks was investigated, where in the first paper, the calculation was based on stratification and Stieltjes ... In this paper, evaluation of effective resistances on more general networks which are underlying networks of association schemes is considered, where by using the algebraic combinatoric structures of association ... Section 4 is devoted to calculation of the effective resistances on underlying resistor networks of association schemes by using the algebraic combinatoric structures of corresponding association schemes ...doi:10.1063/1.2953469 fatcat:mboxx3qpqvberkkc2xf5wopauu

The resistance that is still put up against adopting the language of species reminds me of two other similar resistances. ... At the end, Michael Atiyah came up to me and said: "Nice stuff, but I frankly cannot see how it will ever be applied outside combinatorics", or something to that effect. ...doi:10.1016/0012-365x(95)00143-k fatcat:ga4lhbzmd5drza7q7ga5li2z4e
For practical automated diagnostic systems to continue functioning after failure, they must not only be able to diagnose sensor failures but also be able to tolerate the absence of data from the faulty ... Moreover, attempts to extend the operation of diagnostic capability past sensor failure will necessarily compound those dificulties. ...
