"En los sistemas de distribución de energía el eléctrica típicos es común encontrar cargas de tipo monofásico. Sin embargo estos sistemas son generalmente desbalanceados, debido a que la cargas son desigualmente distribuidas entre las fases, y distorsionados por la gran…

Torres-Saillant’s book contends, as its author explains, that as a region the Caribbean is a differentiated “civilizational” zone produced by the encounter of multiple cultures and by contending political and economic interests. This region, according to him, has produced an…

Introduction: The use of computer-generated 3-dimensional (3-D) anatomical models to teach anatomy has proliferated. However, there is little evidence that these models are educationally effective. The purpose of this study was to test the educational effectiveness of a computer-generated 3-D…

Total internal reflection microscopy (TIRM) measures the position of a Brownian particle above an interface by using its scattering of an evanescent wave. From the knowledge of the trajectory it is possible to reconstruct the interaction potential between the Brownian…

Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction. Over the last few decades it has…

In this study, we focus on the polarization angle of light scattered by terrestrial atmosphere-surface systems. The polarization angle describes the orientation of the plane in which the linearly polarized portion of light propagates. We show for skylight how this…

This essay contests the view that humanity’s centuries-long experience with clocks is marked by a steady increase in time awareness that culminated in the modern compulsion known as “time discipline”. It argues, in contrast, that modern time discipline emerged during…

Electoral authoritarian regimes represent the modal type of political regimes in the developing world. To control electoral outcomes, such regimes may deploy a broad variety of repressive and manipulative measures. Despite their empirical as well as normative relevance, we possess…

"We shortly recall the mathematical and physical aspects of Talbot’s self-imaging effect occurring in near-field diffraction. In the rational paraxial approximation, the Talbot images are formed at distances z = p/q, where p and q are coprimes, and are superpositions…
