Fool’s solitaire on joins and Cartesian products of graphs

open access: yesDiscrete Mathematics, 2015
Peg solitaire is a game generalized to connected graphs by Beeler and Hoilman. In the game pegs are placed on all but one vertex. If $xyz$ form a 3-vertex path and $x$ and $y$ each have a peg but $z$ does not, then we can remove the pegs at $x$ and $y$ and place a peg at $z$. By analogy with the moves in the original game, this is called a jump.

On the Crossing Numbers of Cartesian Products of Stars and Graphs of Order Six

open access: yesDiscussiones Mathematicae Graph Theory, 2013
The crossing number cr(G) of a graph G is the minimal number of crossings over all drawings of G in the plane. According to their special structure, the class of Cartesian products of two graphs is one of few graph classes for which some exact values of ...

Data-driven through-life costing to support product lifecycle management solutions in innovative product development

open access: yes, 2011
Innovative product usually refers to product that comprises of creativity and new ideas. In the development of such a new product, there is often a lack of historical knowledge and data available to be used to perform cost estimation accurately.

The Sigma Coindex of Graph Operations

open access: yesJournal of Mathematics, 2021
The sigma coindex is defined as the sum of the squares of the differences between the degrees of all nonadjacent vertex pairs. In this paper, we propose some mathematical properties of the sigma coindex.

Non-inclusive and inclusive distance irregularity strength for the join product of graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2022
A function ϕ: V(G)→{1, 2, …, k} of a simple graph G is said to be a non-inclusive distance vertex irregular k-labeling of G if the sums of labels of vertices in the open neighborhood of every vertex are distinct and is said to be an inclusive distance ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The Crossing Numbers of Join of Some Graphs with n Isolated Vertices

open access: yesDiscussiones Mathematicae Graph Theory, 2018
There are only few results concerning crossing numbers of join of some graphs. In this paper, for some graphs on five vertices, we give the crossing numbers of its join with n isolated vertices.
