DAGSLAM: causal Bayesian network structure learning of mixed type data and its application in identifying disease risk factors [PDF]

open access: yesBMC Medical Research Methodology
Background Identifying and understanding disease risk factors is crucial in epidemiology, particularly for chronic and noncommunicable diseases that often have complex interrelationships.

On bounding the bandwidth of graphs with symmetry [PDF]

open access: yes, 2015
We derive a new lower bound for the bandwidth of a graph that is based on a new lower bound for the minimum cut problem. Our new semidefinite programming relaxation of the minimum cut problem is obtained by strengthening the known semidefinite ...

The Square of Some Generalized Hamming Graphs

open access: yesMathematics, 2023
In this paper, we study the square of generalized Hamming graphs by the properties of abelian groups, and characterize some isomorphisms between the square of generalized Hamming graphs and the non-complete extended p-sum of complete graphs.

Perfect 2‐colorings of Hamming graphs [PDF]

open access: yesJournal of Combinatorial Designs, 2021
AbstractWe consider the problem of existence of perfect 2‐colorings (equitable 2‐partitions) of Hamming graphs with given parameters. We start with conditions on parameters of graphs and colorings that are necessary for their existence. Next we observe known constructions of perfect colorings and propose some new ones giving new parameters. At last, we

On the $$(k,\ell )$$ ( k , ℓ ) -anonymity of networks via their k-metric antidimension

open access: yesScientific Reports, 2023
This work focuses on the $$(k,\ell )$$ ( k , ℓ ) -anonymity of some networks as a measure of their privacy against active attacks. Two different types of networks are considered.

s-Elusive codes in Hamming graphs [PDF]

open access: yesDesigns, Codes and Cryptography, 2021
A code is a subset of the vertex set of a Hamming graph. The set of $s$-neighbours of a code is the set of all vertices at Hamming distance $s$ from their nearest codeword. A code $C$ is $s$-elusive if there exists a distinct code $C'$ that is equivalent to $C$ under the full automorphism group of the Hamming graph such that $C$ and $C'$ have the same ...

Multipartite information of free fermions on Hamming graphs

open access: yesNuclear Physics B, 2023
We investigate multipartite information and entanglement measures in the ground state of a free-fermion model defined on a Hamming graph. Using the known diagonalization of the adjacency matrix, we solve the model and construct the ground-state ...

Radio Number of Hamming Graphs of Diameter 3

open access: yesTheory and Applications of Graphs, 2022
For $G$ a simple, connected graph, a vertex labeling $f:V(G)\to \Z_+$ is called a \emph{radio labeling of $G$} if it satisfies $|f(u)-f(v)|\geq\diam(G)+1-d(u,v)$ for all distinct vertices $u,v\in V(G)$.

Hamming-shifting graph of genomic short reads: Efficient construction and its application for compression.

open access: yesPLoS Computational Biology, 2021
Graphs such as de Bruijn graphs and OLC (overlap-layout-consensus) graphs have been widely adopted for the de novo assembly of genomic short reads. This work studies another important problem in the field: how graphs can be used for high-performance ...
