This paper addresses two very important, but usually neglected, aspects of Argentina's federal revenue-sharing system. The first aspect refers to the horizontal tensions present -in addition to the traditional vertical o...

En los últimos años, se ha desarrollado un gran interés por la producción de polímeros denominados funcionales o specialties. Los mismos se destacan por poseer algunas propiedades particulares que dan lugar a aplica...

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...

"En este proyecto se investiga el rol de acopio en las estrategias de comercialización de granos en función de los objetivos de maximización de ingresos y minimización de riesgos desde el punto de vista de los produc...

In this paper, we present a new model of an artificial immune system (AIS), based on the process that suffers the T-Cell, it is called T-Cell Model. It is used for solving constrained (numerical) optimization problems. T...

The study of phenomena occurring in a turbulent fluid has been successively improved during the last 40 years. Speci cally, the concentration of a substance advected by the turbulence has received most of the attention,...

In this paper, we present a small econometric model and simulate with it some possible consequences of the Argentine monetary reform of June 14, 1985. First, we derive some theoretical properties of the nonlinear recursi...

Este trabajo presenta una versión estocástica de un modelo de generaciones superpuestas para una economía con dos tipos de bienes (durables y no durables) y analiza algunas de sus implicaciones con respecto a las deci...

This paper uses an intertemporal general equilibrium asset pricing model to study the term structure of interest rates. In this model, anticipations, risk aversion, investment alternatives, and preferences about the timi...

An analogy with the way ant colonies function has suggested the definition of a new computational paradigm, which we call ant system (AS). We propose it as a viable new approach to stochastic combinatorial optimization. ...

BACKGROUND: The evolutionary analysis of molecular sequence variation is a statistical enterprise. This is reflected in the increased use of probabilistic models for phylogenetic inference, multiple sequence alignment, a...

We present a new model for computing the spectral evolution of stellar populations at ages between 100,000 yr and 20 Gyr at a resolution of 3 A across the whole wavelength range from 3200 to 9500 A for a wide range of me...

The parameterized extinction data of Fitzpatrick and Massa (1986, 1988) for the ultraviolet and various sources for the optical and near-infrared are used to derive a meaningful average extinction law over the 3.5 micron...

Variable selection is fundamental to high-dimensional statistical modeling, including nonparametric regression. Many approaches in use are stepwise selection procedures, which can be computationally expensive and ignore ...

We describe a program, tRNAscan-SE, which identifies 99-100% of transfer RNA genes in DNA sequence while giving less than one false positive per 15 gigabases. Two previously described tRNA detection programs are used as ...
