Currently, Draper Laboratory is in the development stages of a gliding autogyro airdrop system. The goal of the project is to design a platform capable of placing small, high value items into urban terrain. Theoretically, autogyros can achieve descent rates…

El artículo revisa las características y evolución de los distintos sistemas de reproducción de imágenes científicas y el impacto que históricamente han tenido en el desarrollo de la investigación y el conocimiento. Para ello realiza un acercamiento crítico a las…

In polyandrous species, sexual selection acts both before (precopulatory) and after
(postcopulatory) mating on traits that are important for reproductive success. Precopulatory traits
are important for mate acquisition and include weapons and ornaments. Postcopulatory traits
include components of sperm quantity…

Early in the twentieth century it was shown that Mendel's laws apply to plants and animals and that genes reside on chromosomes. In the 1950s the double-helix model of DNA inaugurated the molecular biology era, which culminated at the end…

There are many areas in Computer Science where time plays an important role. Artificial Intelligence is one of them. In this particular area Defeasible Logic Programming (DeLP) was developed to cope with incomplete and potentially inconsistent information. This formalism combines…
