The genus Polianthes belongs to the subfamily Agavoideae of the Asparagaceae family formerly known as Agavaceae. The genus is endemic to México and comprises about 15 species, among them is Polianthes tuberosa L. The aim of this work was to…

Sparse Wireless Sensor Networks (SWSN) have been proposed to explore and gather data
from harsh environments. Exploration has been focused on finding optimal paths to obtain knowledge
about the environment while data gathering has mainly been oriented to obtain raw…

The observed expansion of the red lionfish, Pterois volitans (Linnaeus, 1758), in the Caribbean represents one of the most rapid marine fish invasions in the history. The invasion rate of this top predator has resulted in a marked negative effect on local fish populations in the Caribbean by impacting local biodiversity. The main aim of this work was to conduct the…

This thesis explores how an agent can autonomously learn about its environment
just by interacting with it. This is not an easy task, since traditional
machine learning algorithms strongly depend on the user's intervention to define
the data to…

Recientemente se han desarrollado nuevos materiales orgánicos para ser empleados como dispositivos fotovoltaicos y sistemas láser. Para optimizar el funcionamiento de estos dispositivos es necesario tener un conocimiento detallado de los procesos que determinan su eficiencia como lo son: fotogeneración…

U.S. copyright law is facing an interesting moment, where technology is far ahead of the law, and where the evolution of law seems to lead nowhere. This article focuses on recent technological evolution and subsequent legal developments, especially the safe…

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…
