Certain Concepts in m-Polar Fuzzy Graph Structures

open access: yesDiscrete Dynamics in Nature and Society, 2016
We apply the concept of m-polar fuzzy sets to graph structures. We introduce certain concepts in m-polar fuzzy graph structures, including strong m-polar fuzzy graph structure, m-polar fuzzy Di-cycle, m-polar fuzzy Di-tree, m-polar fuzzy Di-cut vertex ...

自余弱弦图(On self-complementary weakly chordal graphs)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2010
The class of self-complementary (sc) weakly chordal graphs is studied, which is a generalization of self-complementary chordal graphs, lower and upper bounds for the number of two-pairs in sc weakly chordal graphs have been obtained.

Correlations in totally symmetric self‐complementary plane partitions

open access: yesTransactions of the London Mathematical Society, 2021
Totally symmetric self‐complementary plane partitions (TSSCPPs) are boxed plane partitions with the maximum possible symmetry. We use the well‐known representation of TSSCPPs as a dimer model on a honeycomb graph enclosed in 1/12 of a hexagon with free ...

Homomorphisms and related contractions of graphs

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
For every homomorphism ϕ of a graph G there exists a contraction θϕ on G¯, the complement of G. Here we study the graph equation ϕ(G)=θϕ(G¯). In the course of our work we show that Hadwiger's Conjecture is true for every self-complementary graph.

On self-graphoidal graphs and their complements

open access: yesKuwait Journal of Science
The graphoidal graph G of graph H is the graph obtained by taking graphoidal cover Ψ of H as vertices and two vertices are adjacent if and only if the corresponding paths have a non-empty intersection.

Can graph-cutting improve microarray gene expression reconstructions? [PDF]

open access: yes, 2008
Microarrays produce high-resolution image data that are, unfortunately, permeated with a great deal of “noise” that must be removed for precision purposes. This paper presents a technique for such a removal process. On completion of this non-trivial task,

Bipartite Diametrical Graphs of Diameter 4 and Extreme Orders

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
We provide a process to extend any bipartite diametrical graph of diameter 4 to an 𝑆-graph of the same diameter and partite sets. For a bipartite diametrical graph of diameter 4 and partite sets 𝑈 and 𝑊, where 2𝑚=|𝑈|≤|𝑊|, we prove that 2𝑚 is a sharp ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

The H-Line Signed Graph of a Signed Graph [PDF]

open access: yes, 2010
For standard terminology and notion in graph theory we refer the reader to Harary; the non-standard will be given in this paper as and when required.
