Measuring temporal, spectral and spatial changes in electrophysiological brain network connectivity. NeuroImage, 91, 282-299. https://doi.org/10.1016/j.neuroimage.2013.12.066

The topic of functional connectivity in neuroimaging is expanding rapidly and many studies now focus on coupling between spatially separate brain regions. These studies show that a relatively small number of large scale networks exist within the brai...

We study critical behavior in the classical cubic dimer model (CDM) in the presence of a finite density of monomers. With attractive interactions between parallel dimers, the monomer-free CDM exhibits an unconventional transition from a Coulomb phase...

We show that thin films of C60 with a thickness ranging from 10 to 100 nm can promote adhesion between a Au thin film deposited on mica and a solution-deposited layer of the elastomer polymethyldisolaxane (PDMS). This molecular adhesion facilitates t... Read More about Fullerenes as adhesive layers for mechanical peeling of metallic, molecular and polymer thin films.
