Synchronization in small-world systems

M Barahona, LM Pecora - Physical review letters, 2002 - APS
We quantify the dynamical implications of the small-world phenomenon by considering the
generic synchronization of oscillator networks of arbitrary topology. The linear stability of the …

SC3: consensus clustering of single-cell RNA-seq data

…, W Reik, M Barahona, AR Green, M Hemberg - Nature …, 2017 - nature.com

a random walker moving on the graph. Under the single condition that M is ergodic, namely …

On the stability of the Kuramoto model of coupled nonlinear oscillators

…, N Motee, M Barahona - Proceedings of the 2004 …, 2004 - ieeexplore.ieee.org
We provide an analysis of the classic Kuramoto model of coupled nonlinear oscillators that
