Dealing with time constraints in the design of distributed real-time systems is a challenge in the future trends on distributed computing. Time constraints must be considered, projected and derived onto all the layered structure components of the distributed system. This time constraints consideration, projection and derivation must be also done along all(More)
We present a numerical study of the self-similar solutions of the Localized Induction Approximation of a vortex filament. These self-similar solutions, which constitute a one-parameter family, develop a singularity at finite time. We study a number of boundary conditions that allow us reproduce the mechanism of singularity formation. Some related questions(More)
Amyloid-beta (A beta) is the main component of senile plaques, one of the hallmarks of Alzheimer's disease. Our results showed that A beta(25-35) decreased neuronal viability while it increased generation of reactive oxygen species (ROS). Under these circumstances, albumin (BSA) prevented ROS production and neuronal death in a dose- and time-dependent(More)
Amyloid-β (Aβ), Aβ40, Aβ42, and, recently, Aβ25-35 have been directly implicated in the pathogenesis of Alzheimer's disease. We have studied the effects of Aβ on neuronal death, reactive oxygen species (ROS) production, and synaptic assembling in neurons in primary culture. Aβ25-35, Aβ40, and Aβ42 significantly decreased neuronal viability, although Aβ25-35(More)
We investigate the regularization of Moore's singularities by surface tension in the evolution of vortex sheets and its dependence on the Weber number (which is inversely proportional to surface tension coefficient). The curvature of the vortex sheet, instead of blowing up at finite time t 0 , grows exponentially fast up to a O(We) limiting value close to t(More)
