Quantifying Uncertainty in Brain Network Measures using Bayesian Connectomics
Frontiers in Computational Neuroscience, 2014 The wiring diagram of the human brain can be described in terms of graph measures that characterize structural regularities. These measures require an estimate of whole-brain structural connectivity for which one may resort to deterministic or ...

Interval Type 2 Fuzzy Set in Fuzzy Shortest Path Problem
Mathematics, 2016 The shortest path problem (SPP) is one of the most important combinatorial optimization problems in graph theory due to its various applications. The uncertainty existing in the real world problems makes it difficult to determine the arc lengths exactly.

The niche graphs of interval orders [PDF]
Discussiones Mathematicae Graph Theory 34 (2014) 353-359, 2013 The niche graph of a digraph $D$ is the (simple undirected) graph which has the same vertex set as $D$ and has an edge between two distinct vertices $x$ and $y$ if and only if $N^+_D(x) \cap N^+_D(y) \neq \emptyset$ or $N^-_D(x) \cap N^-_D(y) \neq \emptyset$, where $N^+_D(x)$ (resp. $N^-_D(x)$) is the set of out-neighbors (resp. in-neighbors) of $x$ in

Time estimation and beta segregation: An EEG study and graph theoretical approach. [PDF]
PLoS ONE, 2018 Elucidation of the neural correlates of time perception constitutes an important research topic in cognitive neuroscience. The focus to date has been on durations in the millisecond to seconds range, but here we used electroencephalography (EEG) to ...

Equivalence of the filament and overlap graphs of subtrees of limited trees [PDF]
Discrete Mathematics & Theoretical Computer Science, Vol. 19 no.
1, Graph Theory (June 20, 2017) dmtcs:1274, 2015 The overlap graphs of subtrees of a tree are equivalent to subtree filament graphs, the overlap graphs of subtrees of a star are cocomparability graphs, and the overlap graphs of subtrees of a caterpillar are interval filament graphs. In this paper, we show the equivalence of many more classes of subtree overlap and subtree filament graphs, and equate ...

Scientific Reports, 2023 In fear conditioning with time intervals between the conditioned (CS) and unconditioned (US) stimuli, a neural representation of the CS must be maintained over time to be associated with the later US.

Theory and Application of Interval-Valued Neutrosophic Line Graphs
Journal of MathematicsNeutrosophic graphs are used to model inconsistent information and imprecise data about any real-life problem. It is regarded as a generalization of intuitionistic fuzzy graphs.

Sturm-Hurwitz Theorem for quantum graphs [PDF]
arXiv, 2023 We prove upper and lower bounds for the number of zeroes of linear combinations of Schr\"odinger eigenfunctions on metric (quantum) graphs. These bounds are distinct from both the interval and manifolds. We complement these bounds by giving non-trivial examples for the lower bound as well as sharp examples for the upper bound.

Spectral analysis of the matrix Sturm–Liouville operator
Boundary Value Problems, 2019 The self-adjoint matrix Sturm–Liouville operator on a finite interval with a boundary condition in general form is studied. We obtain asymptotic formulas for the eigenvalues and the weight matrices of the considered operator.
