A Novel Description on Vague Graph with Application in Transportation Systems

open access: yesJournal of Mathematics, 2021
Fuzzy graph (FG) models embrace the ubiquity of existing in natural and man-made structures, specifically dynamic processes in physical, biological, and social systems.

Regular handicap graphs of order n ≡ 4 (mod 8)

open access: yesElectronic Journal of Graph Theory and Applications, 2022
A handicap distance antimagic labeling of a graph G = (V, E) with n vertices is a bijection f : V → {1, 2, …, n} with the property that f(xi)=i, the weight w(xi) is the sum of labels of all neighbors of xi, and the sequence of the weights w(x1),w(x2),…,w(

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Distance-Locally Disconnected Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2013
For an integer k ≥ 1, we say that a (finite simple undirected) graph G is k-distance-locally disconnected, or simply k-locally disconnected if, for any x ∈ V (G), the set of vertices at distance at least 1 and at most k from x induces in G a disconnected

Distance-regular graph with large a1 or c2 [PDF]

open access: yes, 2010
In this paper, we study distance-regular graphs $\Gamma$ that have a pair of distinct vertices, say x and y, such that the number of common neighbors of x and y is about half the valency of $\Gamma$.

On the metric dimension of imprimitive distance-regular graphs

open access: yes, 2016
A resolving set for a graph $\Gamma$ is a collection of vertices $S$, chosen so that for each vertex $v$, the list of distances from $v$ to the members of $S$ uniquely specifies $v$.

A duality between pairs of split decompositions for a Q-polynomial distance-regular graph [PDF]

open access: yesDiscrete Mathematics, 2007
Let @C denote a Q-polynomial distance-regular graph with diameter D>=3 and standard module V. Recently, Ito and Terwilliger introduced four direct sum decompositions of V; we call these the (@m,@n)-split decompositions of V, where @m,@[email protected]?{@

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

Research on 7-distance set with DG(XD)=C11

open access: yesJournal of Hebei University of Science and Technology, 2016
A planar point set X is called a k-distance set if there are exactly k distances between two distinct points in X. Let d(x,y) be the distance of any two distinct points x,y. Let diameter D=D(X) be the longest distance of X.

A Conjecture of Biggs Concerning the Resistance of a Distance-Regular Graph [PDF]

open access: yesElectronic Journal of Combinatorics, 2010
Biggs conjectured that the resistance between any two points on a distance-regular graph of valency greater than 2 is bounded by twice the resistance between adjacent points.
