Regular embeddings of a graph [PDF]

Pacific Journal of Mathematics, 1983
In this paper we study embeddings of a graph G in Euclidean space R" that are 'regular' in the following sense: given any two distinct vertices u and v of G, the distance between the corresponding points in R" equals a if u and v are adjacent, and equals β otherwise.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Structured Sparsity with Group-Graph Regularization

, 2015
In many learning tasks with structural properties, struc-tural sparsity methods help induce sparse models, usu-ally leading to better interpretability and higher gener-alization performance.

Building a Graph Signal Processing Model Using Dynamic Time Warping for Load Disaggregation

Sensors, 2020
Building on recent unsupervised Non-intrusive load monitoring (NILM) algorithms that use graph Laplacian regularization (GLR) and achieve state-of-the-art performance, in this paper, we propose a novel unsupervised approach to design an underlying graph ...

Dissecting the Ecological Structure of Health and Disease in the Global Gut Microbiome

Advanced Science, EarlyView.
We introduce Wiredancer, a framework that identifies three continuous ecological factors of the gut microbiota. These factors exhibit distinct patterns across health and disease, jointly capturing disrupted ecological stability and offering a new perspective for precision diagnostics and therapeutic strategies.

GDNConv: A Novel Graph Deformation Network for Robust Representation Learning on Noisy Graph Structures

IEEE Access
Graph Neural Networks have emerged as powerful tools for analyzing graph-structured data. However, their performance often varies across datasets due to challenges such as noisy edges, sparse connectivity, and over-smoothing in deep layers.

Factorizations of regular graphs

Journal of Combinatorial Theory, Series B, 1992
Let G be a k-regular graph of order 2n such that \(k\geq n\). \textit{A. J. W. Hilton} [J. Graph Theory 9, 193-196 (1985; Zbl 0624.05050)] proved that G contains at least \(\lfloor k/3\rfloor\) edge-disjoint 1-factors. Hilton's theorem is improved in this paper that G contains at least \(\lfloor k/2\rfloor\) edge-disjoint 1-factors.
