The Unhiggs
We examine a scenario where the Higgs is part of an approximate conformal
field theory, and has a scaling dimension greater than one. Such an unparticle
Higgs (or Unhiggs) can still break electroweak symmetry and unitarize WW
scattering, but its gauge couplings are suppressed. An Unhiggs model has a
reduced sensitivity of the weak scale to the cutoff, and can thus provide a
solution to the little hierarchy problem.Comment: 21 pages, 9 figures; v2: further discussion, references added,

Supersymmetry and Electroweak Breaking in the Interval
Hypermultiplets are considered in the five-dimensional interval where all
fields are continuous and the boundary conditions are dynamically obtained from
the action principle. The orbifold boundary conditions are obtained as
particular cases. We can interpret the Scherk-Schwarz supersymmetry breaking as
a misalignment of boundary conditions while a new source of supersymmetry
breaking corresponding to a mismatch of different boundary parameters is
identified. The latter can be viewed as coming from boundary supersymmetry
breaking masses for hyperscalars and the nature of the corresponding
supersymmetry breaking parameter is analyzed. For some regions of the parameter
space where supersymmetry is broken (either by Scherk-Schwarz boundary
conditions or by boundary hyperscalar masses) electroweak symmetry breaking can
be triggered at the tree level.Comment: 28 pages, 5 figure
The Majorization Arrow in Quantum Algorithm Design
We apply majorization theory to study the quantum algorithms known so far and
find that there is a majorization principle underlying the way they operate.
Grover's algorithm is a neat instance of this principle where majorization
works step by step until the optimal target state is found. Extensions of this
situation are also found in algorithms based in quantum adiabatic evolution and
the family of quantum phase-estimation algorithms, including Shor's algorithm.
We state that in quantum algorithms the time arrow is a majorization arrow.Comment: REVTEX4.b4 file, 4 color figures (typos corrected.
Preliminary morpho-structural study of a pig population in the province of Corrientes (Argentina)
A preliminary study of the morphostructural characteristics of a sample of the population of Creole Argentine pigs formed by 34 animals of 10 months of age from 12 farms belonging to 3 departments of Corrientes Province, Argentina, based principally on exteriorists and morphologic aspects is presented in this work. The animals presented rectilinear profiles, sub-concave and concave front, Iberian, celtic and asian type ears, red, yellow, white and spotted coats, white, black and white with gray rows hooves, pink and dark mucosaes. They all presented hair and females had between 8 and 15 nipples. The comparative analysis among departments for the quantitative variables and indexes, shows significant differences (p<0.05) for most of them, except for length of the croup, thorax perimeter, facial index, relative depth of the chest, index metacarpus - thoracic and index of load of the cane, in which an homogeneous behaviour was stated in the whole population. It is pending the development of a full work where, the samples of animals are enlarged to achieve a complete description and the genetic characterization of the pigs, to confirm the presence of different varieties and its relationship with the iberic trunk.En este trabajo se presenta un estudio preliminar de las características morfoestructurales de una muestra de la población de cerdos criollos argentinos formada por 34 ejemplares mayores de 10 meses, de 12 establecimientos rurales pertenecientes a 3 departamentos de la Provincia de Corrientes, Argentina, basado principalmente en aspectos exterioristas y morfológicos. Se encontraron perfiles rectilíneos, subconcavilíneos, concavilíneos y ultraconcavilíneos, orejas asiáticas, ibéricas y célticas, capas negras, coloradas y bayas, claras y overas, pezuñas blancas enteras y con vetas de color pizarra, y negras, mucosas rosadas y pigmentadas, todos presentaban pelos y de 8 a 15 mamas las hembras, hallándose mamellas en un porcentaje de la muestra. El análisis comparativo entre departamentos para las variables cuantitativas e índices zoométricos, muestra diferencias significativas (p<0,05) para la mayoría, a excepción longitud de la grupa, perímetro torácico, índice facial, profundidad relativa del pecho, índice metacarpo-torácico e índice de carga de la caña, en las cuales se constató un comportamiento homogéneo en toda la población. Queda pendiente el desarrollo de un trabajo donde, se amplíe la muestra de animales medidos para lograr una descripción completa y donde se profundice en la caracterización genética, para afirmar la presencia de variedades y su relación con el tronco ibérico

Los parámetros cualitativos muestran que es una población muy homogénea y por lo tanto no pueden establecerse variedades basadas en éstas
