There were no clear differences in the spines between the Arc and Arc cells in the N15 group, thereby excluding the possibility that only neurons that already had spines with a different morphology preferentially expressed Arc during exploratory behavior.
For output normal arc a' t, p'), the place p' must be continuous by definition.
Finally, normal arc volcanics (tholeiites) cap the subduction initiation sequence (Stern et al. 2012).
They mark the transition between highly depleted mantle sources and the high degrees of fluxed melting at shallow levels that generated boninites and normal arc volcanism (Reagan et al. 2008).
Each of normal arc from a place, test arc, and inhibitory arc has a threshold by which the parameter assigned to the transition at its head is controlled.
Arcs are classified into three types: normal arc, test arc, and inhibitory arc.
Each arc is labeled with either normal, test, or inhibitory, and arc labeled with normal (resp., test, inhibitory) is called normal arc (resp., test arc, inhibitory arc).
A normal arc from a place or a test arc (an inhibitory arc) can participate in activating (repressing) a transition at its head, as far as the content of a place at its tail is over the threshold.
An arc (u, v) is a normal arc if v is a normal vertex.
"Process connector", "associate connector" and "inhibitory connector" correspond to normal arc, test arc and inhibitory arc, respectively.
