Resonance graphs of plane bipartite graphs as daisy cubes

open access: yesDiscrete Applied Mathematics, 2023
We characterize plane bipartite graphs whose resonance graphs are daisy cubes, and therefore generalize related results on resonance graphs of benzenoid graphs, catacondensed even ring systems, as well as 2-connected outerplane bipartite graphs. Firstly, we prove that if $G$ is a plane elementary bipartite graph other than $K_2$, then the resonance ...

Topological Resonances on Quantum Graphs [PDF]

open access: yesAnnales Henri Poincaré, 2018
In this paper, we try to put the results of Smilansky and al. on "Topological resonances" on a mathematical basis.A key role in the asymptotic of resonances near the real axis for Quantum Graphs is played by the set of metrics for which there exists compactly supported eigenfunctions. We give several estimateof the dimension of this semi-algebraic set,

Graph Reasoning Module for Alzheimer’s Disease Diagnosis: A Plug-and-Play Method

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Recent advances in deep learning have led to increased adoption of convolutional neural networks (CNN) for structural magnetic resonance imaging (sMRI)-based Alzheimer’s disease (AD) detection.

A novel short-frequency slip fault energy distribution-based demodulation technique for gear diagnosis and prognosis

open access: yesInternational Journal of Advanced Robotic Systems, 2020
To conduct diagnosis and prognosis of gears, this paper introduces a novel short-frequency slip fault energy distribution-based demodulation method. As an essential step of the method, the resonance-based sparse signal decomposition algorithm is firstly ...

Network alignment and similarity reveal atlas-based topological differences in structural connectomes

open access: yesNetwork Neuroscience, 2021
The interactions between different brain regions can be modeled as a graph, called connectome, whose nodes correspond to parcels from a predefined brain atlas.

Resonance graphs of fullerenes

open access: yesArs Mathematica Contemporanea, 2016
A fullerene G is a 3 -regular plane graph consisting only of pentagonal and hexagonal faces. The resonance graph R ( G ) of G reflects the structure of its perfect matchings. The Zhang-Zhang polynomial of a fullerene is a counting polynomial of resonant structures called Clar covers.

Peripheral Convex Expansions of Resonance Graphs [PDF]

open access: yesOrder, 2020
In this paper, we show that the resonance graph of a plane elementary bipartite graph $G$ can be obtained from an edge by a sequence of peripheral convex expansions with respect to a reducible face decomposition of $G$ if and only if the infinite face of $G$ is forcing.

Resonances and Partial Delocalization on the Complete Graph [PDF]

open access: yesAnnales Henri Poincaré, 2014
Random operators may acquire extended states formed from a multitude of mutually resonating local quasi-modes. This mechanics is explored here in the context of the random Schrödinger operator on the complete graph. The operators exhibits local quasi modes mixed through a single channel.
