A loosely coupled distributed system is composed by nodes, usually heterogenous, connected by a network. These systems have enormous aggregate computing potential. However most of this potential is not realized unless th...

Migration of individuals allows a fruitful interaction between subpopulations in the island model, a well known distributed approach for evolutionary computing, where separate subpopulations evolve in parallel. This mode...

Processor and network management have a great impact on the performance of Distributed Memory Parallel Computers. Dynamic Process Migration allows load balancing and communication balancing at execution time. Managing th...

La fracción acuosa del extracto etanólico obtenido de las hojas (AFL) de Cissampelos sympodialis ha sido evaluada con respecto a la actividad antiinflamatoria, ya que en medicina popular es usada para esta finalidad. E...

Twelve compounds were isolated from the rhizoma of Paris polyphylla Smith var. pubescens Handel-Mazzetti. Based on spectral data, the isolated compounds were identified as stigmasterol (1), β- Ecdysterone (2), Diosgenin...

We develop a simple model for computing planetary formation based on the core instability model for the gas accretion and the oligarchic growth regime for the accretion of the solid core. In this model several planets ca...

Asymmetric or heterogeneous multi-core (AMC) architectures have definite performance, performance per watt and fault tolerance advantages for a wide range of workloads. We propose a 16 core AMC architecture mixing simple...

In this paper we present a new mixed-variables symplectic tree code for planetesimal dynamics, which allows to use a very large number of particles in numerical simulations of planet disk interaction. Furthermore, we dis...
