Identifying bimodality in data using a proximity-based null model with an application to classifying cell cycle phases using oxidative stress
Michelle Kovarik, Tyler Allcroft, Per Sebastian Skardal
Detecting communities in large complex networks has found a wide range of applications in physical, biological, and social sciences by identifying mesoscopic groups based on the li…
Pattern formation and oscillations in nonlinear random walks on networks
Per Sebastian Skardal
Random walks represent an important tool for probing the structural and dynamical properties of networks and modeling transport and diffusion processes on networks. However, when i…
Dynamics of Nonlinear Random Walks on Complex Networks
Per Sebastian Skardal, Sabina Adhikari
In this paper we study the dynamics of nonlinear random walks. While typical random walks on networks consist of standard Markov chains whose static transition probabilities dictat…
Unidirectional Pinning and Hysteresis of Spatially Discordant Alternans in Cardiac Tissue
Per Sebastian Skardal, Alain Karma, Juan G. Restrepo
Spatially discordant alternans is a widely observed pattern of voltage and calcium signals in cardiac tissue that can precipitate lethal cardiac arrhythmia. Using spatially coupled…
