On Page Number of N-free Posets

open access: yesElectronic Notes in Discrete Mathematics, 2006
Abstract In this paper we deal with the page number of partially ordered sets (posets). In particular, we find the page number of some N -free posets whose root graphs form a family of planar posets with known page number.

The mixed page number of graphs

open access: yesTheoretical Computer Science, 2022
A linear layout of a graph typically consists of a total vertex order, and a partition of the edges into sets of either non-crossing edges, called stacks, or non-nested edges, called queues. The stack (queue) number of a graph is the minimum number of required stacks (queues) in a linear layout.

On the page-number of a circulant graph

open access: yesAKCE International Journal of Graphs and Combinatorics
The page-number of a graph G, denoted by p(G), is the minimum k such that G has an embedding in a k-book. The circulant graph C(m, n) is such a graph that its vertex set is [Formula: see text] and edge set is [Formula: see text], where m, n are positive ...

Track Layouts of Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2004
A \emph(k,t)-track layout of a graph G consists of a (proper) vertex t-colouring of G, a total order of each vertex colour class, and a (non-proper) edge k-colouring such that between each pair of colour classes no two monochromatic edges cross.

Two Results on Layered Pathwidth and Linear Layouts

open access: yesJournal of Graph Algorithms and Applications, 2021
Layered pathwidth is a new graph parameter studied by Bannister et al. (2015). In this paper we present two new results relating layered pathwidth to two types of linear layouts. Our first result shows that, for any graph $G$, the stack number of $G$ is

Stacks, Queues and Tracks: Layouts of Graph Subdivisions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
A \emphk-stack layout (respectively, \emphk-queuelayout) of a graph consists of a total order of the vertices, and a partition of the edges into k sets of non-crossing (non-nested) edges with respect to the vertex ordering.

On Linear Layouts of Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2004
In a total order of the vertices of a graph, two edges with no endpoint in common can be \emphcrossing, \emphnested, or \emphdisjoint. A \emphk-stack (respectively, \emphk-queue, \emphk-arch) \emphlayout of a graph consists of a total order of the ...

MatGel: A MATLAB program for quantitative analysis of 2D polyacrylamide electrophoresis (2D-PAGE) protein gel images

open access: yesMethodsX, 2022
Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) is widely used in proteomics studies. Hundreds of proteins extracted from a biological sample can be separated and visualized on a 2D-PAGE gel.
