Russian Doll Renormalization Group and Superconductivity

We show that an extension of the standard BCS Hamiltonian leads to an infinite number of condensates with different energy gaps and self-similar properties, described by a cyclic RG flow of the BCS coupling constant which returns to its original value after a finite RG time.Comment: 4 pages, 2 figs, RevTex

Computing vs. Genetics

This chapter first presents the interrelations between computing and genetics, which both are based on information and, particularly, self-reproducing artificial systems. It goes on to examine genetic code from a computational viewpoint. This raises a number of important questions about genetic code. These questions are stated in the form of an as yet unpublished working hypothesis. This hypothesis suggests that many genetic alterations are caused by the last base of certain codons. If this conclusive hypothesis were to be confirmed through experiementation if would be a significant advance for treating many genetic diseases

Los números en El otoño del patriarca : símbolos recurrentes y supersticiosos = Numbers on The autumn of the patriarch : recurrent and superstitious symbols

Este texto busca evidenciar cómo los números no sólo símbolos que representan cantidades, sino que también son símbolos que representan cargas culturales y esotéricas de los pueblos -- En la novela El otoño del patriarca de Gabriel García Márquez, pueden identificarse algunas estrategias narrativas que hacen uso de los números para permitirle al lector adentrarse en la realidad imaginaria y en las creencias y costumbres del país caribeño donde reina el patriarca -- Estos números “simbólicos y culturales” que recurrentemente hacen parte de la narración, se analizan desde las creencias y explicaciones sociales, filosóficas y religiosas, para así poder interpretar su carga esotérica y supersticiosa dentro de la novel

Analysis of the optimal deployment location for tidal energy converters in the mesotidal Ria de Vigo (NW Spain)

The potential power output expected from the installation of a tidal farm near the mesotidal Ria de Vigo (NW Spain) is assessed using two different tidal stream energy converters (TEC). For this, the results of a previous resource assessment based on a 28-day long hydrodynamic simulation are used. From this data we identify the areas susceptible of hosting the farms, select the optimal location for them, and assess the total available and extractable energy for each turbine type. Finally, using a simple farm design based on standard inter-turbine separation, we estimate the expected power supplied by the farm. Irrespective of the site, the total available tidal power in the areas susceptible of hosting the farms is around 150 MW; at the optimal location, the hourly extractable power is about 22.5 MW, of which only between 10% and 15% can be harnessed by the designed farms, powering between 4411 and 6638 homes. A local analysis of the most energetic subregions within these sites increases this ratio up to 30%. Nevertheless, the power output is sufficient to fulfil the needs of between 1660 and 2213 households, depending on the chosen site and the selected TEC.Peer ReviewedPostprint (author's final draft
