Dynamics in a distributed system are self-stabilizing if they are guaranteed to reach a stable state regardless of how the system is initialized. Game dynamics are uncoupled if each player’s behavior is independent of the other players’ preferences. For uncoupled players, recognizing an equilibrium is a distributed computational task. Self-stabilizing uncoupled dynamics, then, capture both resi...

OBJECTIVES Active plates dynamize a fracture by elastic suspension of screw holes within the plate. We hypothesized that dynamic stabilization with active plates delivers stronger healing relative to standard compression plating. METHODS Twelve sheep were randomized to receive either a standard compression plate (CP) or an active plate (ACTIVE) for stabilization of an anatomically reduced tib...

the present work is aimed to find a new and efficient type of antioxidants for polypropylene. hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one, generally known as thymolphthalein, on thermo-oxidative stability of polypropylene in solid and melt states were evaluated and compared with those of songnox 1010, an efficient commercially used antioxidant for the po...

We show the global stabilization of the chemostat with nonmonotonic growth, adding a new species as a "biological" control, in presence of different removal rates for each species. This result is obtained by an extension of the Competitive Exclusion Principle in the chemostat, for the case of two species with different removal rates and at least one nonmonotonic response.

Silver nano-particles have different biological applications due to their compatibility. Chemical methods usually result in remaining some amounts of toxic reactions on the nano-particles. For this reason, the use of plants as sustainable and accessible resources in preparation of compatible nano-particles has attracted a lot of attention in the recent years. This research investigated the gree...

A development quadratic model of the heterogeneous biological population consisting of a few sub-populations is investigated. The classic stabilization problem of solutions for the system of ordinary quadratic differential equations, which describing this model, is solved. Examples are given. 2013 Elsevier Inc.

A self-stabilizing system is one which can recover from transient faults in a nite number of steps. We present a theory for determining if a behavior speciication can be satissed with a self-stabilizing system and if not, then what the largest self-stabilizing subset and smallest self-stabilizing superset of the speciication is. The eeects of self-stabilizing behavior on the control of discrete...
