Smart Contract Invariants Protect Against Cybercriminals
Sofia Bobadilla, Humaira Afrin, Angela Novelli +1
Blockchains are among the most adversarial environments in computing. Billions are stolen by cybercriminals who exploit vulnerabilities. This is an open problem and no concept or t…
A Thomson-type variational principle for diffusion coefficients
Assaf Shapira
We consider reversible interacting particle systems with conserved number of particles. A standard variational formulation describes the diffusion coefficient of such models as the…
Hydrodynamic limit of the directed exclusion process
Ellen Saada, Federico Sau, Assaf Shapira
We derive the Euler (hyperbolic) hydrodynamic limit for the directed exclusion process (DEP), a one-dimensional conservative interacting particle system that preserves particle-hol…
Scaling Relations For The CLG's Critical Exponents
Clément Erignoux, Assaf Shapira, Marielle Simon
We consider, in any dimension, the constrained lattice gas introduced by Rossi et al., which is an exclusion process on a d-dimensional lattice following the additional constraint…
Hydrodynamic behavior near dynamical criticality of a facilitated conservative lattice gas
Clément Erignoux, Alexandre Roget, Assaf Shapira +1
We investigate a -conservative lattice gas exhibiting a dynamical active-absorbing phase transition with critical density . We derive the hydrodynamic equation for this m…
