Map Generalization as a Graph Drawing Problem

, 1995
A map may be regarded as a plane graph drawing; and, with the growth of the field of computer cartography, a map is increasingly treated as a straight-line plane graph drawing.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Cliques in Graphs Excluding a Complete Graph Minor [PDF]

, 2015
This paper considers the following question: What is the maximum number of k-cliques in an n-vertex graph with no Kt-minor? This question generalises the extremal function for Kt-minors, which corresponds to the k = 2 case.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Exploring the chemodiversity of antimicrobial minalemines from Didemnum granulatum by neutral loss graph

Scientific Reports
In this study, we report on the identification of the active antimicrobial principles from the tunicate Didemnum granulatum. Two new natural products, minalemines G (1) and H (2), were isolated and their structures were elucidated.

Centered colorings in minor-closed graph classes

International audienceA vertex coloring $φ$ of a graph $G$ is $p$-centered if for every connected subgraph $H$ of $G$, either $φ$ uses more than $p$ colors on $H$, or there is a color that appears exactly once on $H$.

Knowledge graph representation of the mappings between seizure semiology and epileptogenic zones

Scientific Reports
Precise epileptogenic zone (EZ) localization remains challenging for epilepsy surgery planning. While seizure semiology provides valuable localization information, subjective interpretation and inter-observer variability limit clinical utility.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Square Roots of Minor Closed Graph Classes

, 2011
Let G be a graph class. The square root of G contains all graphs whose square belong in G. We prove that if G is non-trivial and minor closed, then all graphs in its square root have carving-width bounded by some constant depending only on G.
