Targeting influence in a harmonic opinion model
Zachary M. Boyd, Nicolas Fraiman, Jeremy L. Marzuola +2
Influence propagation in social networks is a central problem in modern social network analysis, with important societal applications in politics and advertising. A large body of w…
Introduction to correlation networks: Interdisciplinary approaches beyond thresholding
Naoki Masuda, Zachary M. Boyd, Diego Garlaschelli +1
Many empirical networks originate from correlational data, arising in domains as diverse as psychology, neuroscience, genomics, microbiology, finance, and climate science. Speciali…
Escape times for subgraph detection and graph partitioning
Zachary M. Boyd, Nicolas Fraiman, Jeremy L. Marzuola +2
We provide a rearrangement based algorithm for fast detection of subgraphs of vertices with long escape times for directed or undirected networks. Complementing other notions o…
Ten-tier and multi-scale supplychain network analysis of medical equipment: Random failure and intelligent attack analysis
Kayvan Miri Lavassani, Zachary M. Boyd, Bahar Movahedi +1
Motivated by the COVID-19 pandemic, this paper explores the supply chain viability of medical equipment, an industry whose supply chain was put under a crucial test during the pand…
A metric on directed graphs and Markov chains based on hitting probabilities
Zachary M. Boyd, Nicolas Fraiman, Jeremy L. Marzuola +3
The shortest-path, commute time, and diffusion distances on undirected graphs have been widely employed in applications such as dimensionality reduction, link prediction, and trip…
Stochastic Block Models are a Discrete Surface Tension
Zachary M. Boyd, Mason A. Porter, Andrea L. Bertozzi
Networks, which represent agents and interactions between them, arise in myriad applications throughout the sciences, engineering, and even the humanities. To understand large-scal…
Converging Shock Flows for a Mie-Grüneisen Equation of State
Scott D. Ramsey, Emma M. Schmidt, Zachary M. Boyd +2
Previous work has shown that the one-dimensional (1D) inviscid compressible flow (Euler) equations admit a wide variety of scale-invariant solutions (including the famous Noh, Sedo…
Collapsing cavities and converging shocks in non-ideal materials
Zachary M. Boyd, Emma M. Schmidt, Scott D. Ramsey +1
As modern hydrodynamic codes increase in sophistication, the availability of realistic test problems becomes increasingly important. In gas dynamics, one common unrealistic aspect…
On the existence of self-similar converging shocks for arbitrary equation of state
Zachary M. Boyd, Scott D. Ramsey, Roy S. Baty
We extend Guderley's problem of finding a self-similar scaling solution for a converging cylindrical or spherical shock wave from the ideal gas case to the case of flows with an ar…
Simplified Energy Landscape for Modularity Using Total Variation
Zachary Boyd, Egil Bae, Xue-Cheng Tai +1
Networks capture pairwise interactions between entities and are frequently used in applications such as social networks, food networks, and protein interaction networks, to name a…
