Unfolding chromatin nets
Unfolding chromatin nets Spiderman doesn’t have anything on neutrophils, which snag microscopic bad guys with webs of chromatin. Wang et al. show that by unfurling chromatin, a histone-modifying protein helps the defensive cells set their traps. During an infection or infl ammation, dying neutrophils spill their DNA to form pathogentrapping NETs (neutrophil extracellular traps). This gooey mate...
متن کاملOptimized Colored Nets Unfolding
As some structural properties, like generative families of positive P-invariants, can only be computed in P/T nets, unfolding of Colored Petri Nets is of interest. However, it may generate huge nets that cannot be stored concretely in memory. In some cases, removing the dead parts of the unfolded net can dramatically reduce its size, but this operation requires the unfolded net to be represente...
متن کاملUnfolding CSPT-nets
Communication structured occurrence nets (csons) are the basic variant of structured occurrence nets which have been introduced to characterise the behaviours of complex evolving systems. A cson has the capability of portraying different types of interaction between systems by using special elements to link with multiple (component) occurrence nets. Communication structured place transition net...
متن کاملDistributed Unfolding of Petri Nets
Some recent Petri net-based approaches to fault diagnosis of distributed systems suggest to factor the problem into local diagnoses based on the unfoldings of local views of the system, which are then correlated with diagnoses from neighbouring supervisors. In this paper we propose a notion of system factorisation expressed in terms of pullback decomposition. To ensure coherence of the local vi...
متن کاملDirected Unfolding of Petri Nets
The key to efficient on-the-fly reachability analysis based on unfolding is to focus the expansion of the finite prefix towards the desired marking. However, current unfolding strategies typically equate to blind (breadth-first) search. They do not exploit the knowledge of the marking that is sought, merely entertaining the hope that the road to it will be short. This paper investigates directe...
