The matching book embeddings of pseudo-Halin graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2023
The book embedding of a graph G is to arrange the set of points of the graph on a line (spine) and embed the edges on the half-plane bounded by the spine so that the edges in the same page do not intersect with each other.

Four pages are indeed necessary for planar graphs

open access: yesJournal of Computational Geometry, 2020
An embedding of a graph in a book consists of a linear order of its vertices along the spine of the book and of an assignment of its edges to the pages of the book, so that no two edges on the same page cross. The book thickness of a graph is the minimum

Research of the backing technology of the book block spine

open access: yesJournal of Graphic Engineering and Design, 2020
The factors influencing the backing process of the book block spine are determined and their priorities are established. The method of backing the spine of book blocks in the production of publications by the method of perfect binding is proposed.

Parameterized Algorithms for Book Embedding Problems

open access: yesJournal of Graph Algorithms and Applications, 2020
A $k$-page book embedding of a graph $G$ draws the vertices of $G$ on a line and the edges on $k$ half-planes (called pages) bounded by this line, such that no two edges on the same page cross. We study the problem of determining whether $G$ admits a $k$-

The Use of a Natural Polysaccharide as a Solidifying Agent and Color-Fixing Agent on Modern Paper and Historical Materials

open access: yesOrganics, 2023
This article presents results on the use of a new material as a solidifying agent and/or color-fixing agent. A special polysaccharide material extracted from the prickly pear cactus (Opuntia ficus indica) was tested on historical materials and modern ...

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.

An introduction to neutron reflectometry [PDF]

open access: yesEPJ Web of Conferences, 2020
Specular neutron reflectivity is a neutron diffraction technique that provides information about the structure of surfaces or thin films. It enables the measurement of the neutron scattering length density profile perpendicular to the plane of a surface ...
