Why a universe as a whole must be a quantum object  [PDF]
Pedro F. González-Díaz
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.35053
Abstract: Technical and physical reasons are given in favor of the idea that single universes, accelerating or not, essentially are quantum-mechanical entities without any classical analogs, even when they are forming part of a given multi- verse.
Is the Cosmic big Trip Just a Classical Wormhole Artifact?  [PDF]
Pedro F. González-Daz
International Journal of Astronomy and Astrophysics (IJAA) , 2011, DOI: 10.4236/ijaa.2011.12012
Abstract: Starting with the original sub-quantum dark energy model, the current accelerating phase of the evolution of the universe is considered by constructing most economical cosmic models that use just general relativity and some dominating quantum effects associated with the probabilistic description of quantum physics. Two of such models are explicitly considered. They support an interpretation of dark energy in terms of the entangled energy of the universe. The model only violates the dominant energy condition quantum mechanically, that is by an amount given by the entanglement energy density, and gives rise to an asymptotically anti-de Sitter wormhole that becomes an asymptotically flat wormhole in the classical limit. It is shown that for most cosmic solutions such a wormhole does not predict any big trip phenomenon when it accretes phantom like energy.
Cosmic Transmutation Conjecture  [PDF]
Pedro F. González-Daz
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.28094
Abstract: This paper analyzes the big trip phenomenon, restricting it to happen only in the context of the multiverse when the involved wormhole is asymptotically flat and recent criticisms are pointless. A new kind of Lorentzian asymptotically anti-de Sitter wormholes is considered in some detail and it is seen that such wormholes cannot contribute the big trip phenomenon. The ideas of big trip, multiverse and Boltzmann brains are then used to advance the conjecture of cosmic transmutation according to which the host universe where one of the mouths of a grown up wormhole is inserted may be converted into a universe similar to the traveling one if the latter contains a civilization which is typical also in the host universe. The origin of life in the context of the multiverse is then briefly discussed.

Sistemas de información en salud: diálogo con Pedro Urra González
Urra González,Pedro;
Salud Colectiva , 2011, DOI: 10.1590/S1851-82652011000100008
Abstract: in this conversation, which took place in havana in october 2010, pedro urra gonzález recounts the creation of cuba's sistema nacional de información en ciencias de la salud (national information system in health sciences) during the 1960s and the founding of the infomed project in the beginning of the 1990s. he describes the epistemological frameworks which supported the development of infomed as a cultural and social process and as a place of confluence of different types of thought, based on a theory of knowledge oriented to respond to the needs of practice and transformation. grounding himself in a conception of information systems as human, social and historical constructions which cannot be treated as artifacts disconnected from the reality that embeds them, he analyzes bibliometric indicators, the open access movement and such regional projects as the scientific electronic library online (scielo) and the red de revistas científicas de américa latina y el caribe, espa?a y portugal (redalyc).
Sistemas de información en salud: diálogo con Pedro Urra González
Pedro Urra González
Salud Colectiva , 2011,
Abstract: En esta charla realizada en La Habana, en octubre de 2010, Pedro Urra González narra el contexto de surgimiento del Sistema Nacional de Información en Ciencias de la Salud de Cuba en la década del '60 y del proyecto Infomed, del cual fue fundador, a inicios de los a os '90. Describe los fundamentos epistemológicos que sustentaron el desarrollo de Infomed como un proceso social y cultural, como espacio de integración de los esfuerzos del conocimiento, basado en una teoría del conocimiento orientada a responder a las necesidades de la práctica y la transformación. A partir de su concepción de los sistemas de información, entendidos como construcciones humanas, sociales e históricas que por lo tanto no pueden ser trasladados como artefactos desconectados de su realidad, analiza los indicadores bibliométricos, el movimiento Open Access y los proyectos regionales como la Scientific Electronic Library Online (SciELO) y la Red de Revistas Científicas de América Latina y el Caribe, Espa a y Portugal (Redalyc).
