On implementing omega in systems with weak reliability and synchrony assumptions
We study the feasibility and cost of implementing --a fundamental failure detector at the core of many algorithms--in systems with weak reliability and synchrony assumptions. Intui...

Fast computation by population protocols with a leader
Fast algorithms are presented for performing computations in a probabilistic population model. This is a variant of the standard population protocol model--in which finite-state ag...

Low-pressure plasma generation inside slender tubes
Low pressure (<50 mTorr) argon discharges inside tubes of a few millimeters in diameter have been studied by means of one- and twodimensional particle-in-cell Monte Carlo colli...
