The Phantom Alignment Strength Conjecture: Practical use of graph matching alignment strength to indicate a meaningful graph match [PDF]
, 2021 The alignment strength of a graph matching is a quantity that gives the practitioner a measure of the correlation of the two graphs, and it can also give the practitioner a sense for whether the graph matching algorithm found the true matching. Unfortunately, when a graph matching algorithm fails to find the truth because of weak signal, there may be ...

Modular Irregularity Strength of Triangular Book Graph [PDF]
arXiv, 2021 This paper deals with the modular irregularity strength of a graph of n vertices, a new graph invariant, modified from the irregularity strength, by changing the condition of the vertex-weight set associate to the well-known irregular labeling from n distinct positive integer to Z_n-the group of integer modulo n. Investigating the triangular book graph

Architecting materials for extremal stiffness, yield and buckling strength [PDF]
arXiv, 2022 This paper proposes a methodology for architecting microstructures with extremal stiffness, yield, and buckling strength using topology optimization. The optimized microstructures reveal an interesting transition from simple lattice like structures for yield-dominated situations to hierarchical lattice structures for buckling-dominated situations.

Percolation on networks with weak and heterogeneous dependency [PDF]
Phys. Rev. E 95, 032301 (2017), 2016 In real networks, the dependency between nodes is ubiquitous; however, the dependency is not always complete and homogeneous. In this paper, we propose a percolation model with weak and heterogeneous dependency; i.e., dependency strengths could be different between different nodes. We find that the heterogeneous dependency strength will make the system
