Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Minimum Spanning Trees and Types of Dissimilarities
European Journal of Combinatorics, 1996 The author surveys and brings together a set of observations concerning dissimilarities, i.e., functions \(d\): \(X^2 \to [0, \infty)\) such that \(d(x,x) = 0\) and such that \(d(x,y) = d(y,x)\), and dissimilarity preorders \(R\) (reflexive and transitive relations) on \(X^2\), \(X\) a finite set, with the emphasis on compatibility relationships which ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, EarlyView.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Minimum Cost Arborescences [PDF]
In this paper, we analyze the cost allocation problem when a group of agents or nodes have to be connected to a source, and where the cost matrix describing the cost of connecting each pair of agents is not necessarily symmetric, thus extending the well ...

Aksioma: Jurnal Program Studi Pendidikan Matematika, 2012 One of useful graph theory to solve the real problems is Minimum Spanning Tree (MST). MST is network optimization problems that can be applied in many fields such as transportations problems and communication network design (Gruber and Raidl, 2005).
