The purpose of this paper is to illustrate the usefulness of Keynes' approach by modeling it using system dynamics. As this technique allows the researcher to place the analysis in time it is especially well suited to the task. It also allows us to see exactly which elements seem to create the...

This paper builds a system-dynamics model of the Mexican economy and tests several propositions regarding policy and income inequality. It concludes, among other things, that one of the most significant developments over the past twenty years has been the declining wage paid to those in the...

Driven flow of a non-equilibrium non-conservative (NENC) system with a mixture of immiscible particles (A,B of molecular weight M<Subscript>A</Subscript>, M<Subscript>B</Subscript>) exhibits self-organizing patterns (segregation, phase-separation, etc.) in steady-state.

Among an infinite number of possible folds, nature has chosen only about 1000 distinct folds to form protein structures. Theoretical studies suggest that selected folds are intrinsically more designable than others; these selected folds are unusually stable, a property called the designability...

We investigate the evolution of asexual populations subject to a large supply of deleterious mutations such that Muller's ratchet operates. In this regime, the accumulation of deleterious mutations takes place continuously with the resulting loss of the least-loaded class of individuals. In the...

Adaptation of populations takes place with the occurrence and subsequent fixation of mutations that confer some selective advantage to the individuals which acquire it. For this reason, the study of the process of fixation of advantageous mutations has a long history in the population genetics...

Dynamical heterogeneities (DH) in low density liquid SiO<Subscript>2</Subscript> have been investigated by molecular dynamics (MD) method. Simulations were done in the basic cube under periodic boundary conditions containing 3000 particles with the pair interatomic potentials, which have a weak electrostatic...</subscript>

The performance of various structure characteristics in the task of indicating structural peculiarities in packings of hard spheres is investigated. Various characteristics based on Voronoi polyhedra, spherical harmonics, and Delaunay simplices are considered together with the pair correlation...
