This question is raised by Cason, Friedman and Hopkins (CFH, 2012) after they firstly found and indexed quantitatively the cycles in a continuous time experiment. To answer this question, we use the d...

We present a joint copula-based model for insurance claims and sizes. It uses bivariate copulae to accommodate for the dependence between these quantities. We derive the general distribution of the po...

Purpose: We previously proposed that Hebbian adjustments that are incompletely synapse specific ("crosstalk") might be analogous to genetic mutations. We analyze aspects of the effect of crosstalk in...
