Structural properties of graph products

Journal of Graph Theory, 2023
AbstractDujmovć, Joret, Micek, Morin, Ueckerdt, and Wood established that every planar graph is a subgraph of the strong product of a graph with bounded treewidth and a path. Motivated by this result, this paper systematically studies various structural properties of cartesian, direct and strong products. In particular, we characterise when these graph

Fractional vs. Ordinary Control Systems: What Does the Fractional Derivative Provide?

Mathematics, 2022
The concept of a fractional derivative is not at all intuitive, starting with not having a clear geometrical interpretation. Many different definitions have appeared, to the point that the need for order has arisen in the field.

Large-Area MoS₂ Films Grown on Sapphire and GaN Substrates by Pulsed Laser Deposition

Nanomaterials, 2023
In this paper, we present the preparation of few-layer MoS2 films on single-crystal sapphire, as well as on heteroepitaxial GaN templates on sapphire substrates, using the pulsed laser deposition (PLD) technique.

Divergent grain boundary oxidation mechanisms in Inconel 718 with pre-tensile and pre-compressive strain state by bending

Journal of Materials Research and Technology
Thermo-mechanical coupling during service induces distinct oxidation behavior in Inconel 718 superalloys. This study systematically examines the oxidation response under pre-tension and pre-compression strains, focusing on microstructural evolution and ...
