The complexity of latching transitions in large scale cortical networks
Abstract. We study latching dynamics, i.e. the ability of a network to hop spontaneously from one discrete attractor state to another, which has been proposed as a model of an inļ¬...

Analysis of Local Quasi-Stationarity Regions in an Urban Macrocell Scenario
ā€”A common simpliļ¬cation in the treatment of random linear channels is the wide-sense stationary and uncorrelated scattering (WSSUS) assumption. For wireless channels, this assu...
