Báo cáo toán học: " Criteria for robustness of heteroclinic cycles in neural microcircuits" potx

... Discussion In this article, we have introduced a testable criterion for robustness for a given cycle of heteroclinic con- nections within constrained settings—this test involves finding the connection ... C 1 perturbations in X . The HC may, however, be robust to a constrained set of perturbations. We explore this in the following sections. 2.1 Conditions for robustness...

In this paper, we investigated various methods of predicting the placement of backchannel continuers, using only limited processing and information that ... by producing a backchannel for all pauses once they reach a certain length. Eleven models were run, starting with a threshold of below 400ms, and increasing the thresh- old value in...
