Decomposition of Anomalous Diffusion in two-state random walks
Abhijit Bera, Kevin. E. Bassler
Two-state stochastic models, where motion alternates between distinct dynamical modes, are widely observed in complex systems. Here we study the Two-State Random Walk (TSRW), which…
Hierarchical Community Detection in Bipartite Networks
Tania Ghosh, Kevin E. Bassler
Many bipartite networks exhibit hierarchical community structure, but existing community detection methods are not well-suited for detecting hierarchy. They also do not effectively…
Graph Symmetry Organizes Exceptional Dynamics in Open Quantum Systems
Eric R. Bittner, Bhavay Tyagi, Kevin E. Bassler
Exceptional points (EPs), indicative of parity-time (PT) symmetry breaking, play a central role in non-Hermitian physics, yet most studies begin from deliberately engineered effect…
Complexity and dynamics of partially symmetric random neural networks
Nimrod Sherf, Si Tang, Dylan Hafner +4
Neural circuits exhibit structured connectivity, including an overrepresentation of reciprocal connections between neuron pairs. Despite important advances, a full understanding of…
Complete Decomposition of Anomalous Diffusion in Variable Speed Generalized Lévy Walks
Abhijit Bera, Kevin E. Bassler
Variable Speed Generalized Lévy Walks (VGLWs) are a class of spatio-temporally coupled stochastic processes that unify a broad range of previously studied models within a single p…
From Chaos to Coherence: Effects of High-Order Synaptic Correlations on Neural Dynamics
Nimrod Sherf, Xaq Pitkow, KreÅ¡imir JosiÄ +1
Recurrent Neural Network models have elucidated the interplay between structure and dynamics in biological neural networks, particularly the emergence of irregular and rhythmic act…
