Network Hierarchy and Pattern Recovery in Directed Sparse Hopfield Networks
Niall Rodgers, Peter Tino, Samuel Johnson
Many real-world networks are directed, sparse and hierarchical, with a mixture of feed-forward and feedback connections with respect to the hierarchy. Moreover, a small number of '…
A look at generalized perfect shuffles
Samuel Johnson, Lakshman Manny, Cornelia A. Van Cott +1

Digraphs are different: Why directionality matters in complex systems
Samuel Johnson
Many networks describing complex systems are directed: the interactions between elements are not symmetric. Recent work has shown that these networks can display properties such as…

Alessio Pagani, Guillem Mosquera, Aseel Alturki +5
Many critical infrastructure systems have network structure and are under stress. Despite their national importance, the complexity of large-scale transport networks means we do no…
