The f0(1370)f_0(1370), f0(1710)f_0(1710), f2(1270)f_2(1270), f2′(1525)f_2'(1525), and K2∗(1430)K_2^*(1430) as dynamically generated states from vector meson - vector meson interaction

We report on some recent developments in understanding the nature of the low-lying mesonic resonances $f_0(1370)$, $f_0(1710)$, $f_2(1270)$, $f_2'(1525)$, and $K_2^*(1430)$. In particular we show that these five resonances can be dynamically generated from vector meson--vector meson interaction in a coupled-channel unitary approach, which utilizes the phenomenologically very successful hidden-gauge Lagrangians to produce the interaction kernel between two vector mesons, which is then unitarized by the Bethe-Salpeter-equation method. The data on the strong decay branching ratios, total decay widths, and radiative decay widths of these five states, and on related $J/\psi$ decay processes can all be well described by such an approach. We also make predictions, compare them with the results of earlier studies, and highlight observables that if measured can be used to distinguish different pictures of these resonances.Comment: 9 pages; Invited talk at workshop CHIRAL'10, Valencia (Spain), June 21-24, 201

La Basílica de Pátzcuaro en Pátzcuaro, México: su innovador sistema estructural en la fachada y cubierta

La basílica de Pátzcuaro es el único vestigio del magno proyecto catedralicio que en el S. XVI concibiera Vasco de Quiroga para la diócesis de Michoacán, es en el último tercio de este siglo que la estructura material de la ex catedral y como producto de solicitaciones sísmicas que se dan a través de tres siglos, el edificio presenta modificaciones en su estructura, presentándose las finales en el S. XIX. La vulnerabilidad sísmica obedece a una obra de fábrica de considerable luz, las intervenciones realizadas en el periodo comprendido de 1850 y 1872, básicamente en la fachada y cubierta, muestran la aplicación de los conocimientos de la época, la singularidad de la cubierta de la basílica, consiste en ser el primer edificio histórico que presenta apoyos discontinuos entre la estructura de madera y la corona del muro, interacción que le otorga un comportamiento elástico resultando en un factor de amortiguamiento ante solicitaciones sísmicas. Una singularidad lo constituye la interacción entre la estructura de madera y el mecanismo de apoyo en la corona del muro como una adecuación de la viga de Winkler.5.- Patrimonios Urbano, Rural, Industrial y Religioso.

Three body systems with strangeness and exotic systems

We report on four $\Sigma$'s and three $\Lambda$'s, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave $(1/2)^+$ resonances found by solving the Faddeev equations in the coupled channel approach, which can be associated to the existing $S$ = -1, $J^P= 1/2^+$ low lying baryon resonances. On the other hand we also report on a new, hidden strangeness $N^*$ state, mostly made of $K \bar{K} N$, with mass around 1920 MeV, which we think could be responsible for the peak seen in the $\gamma p \to K^+ \Lambda$ around this energy. Finally we address a very novel topic in which we show how few body systems of several $\rho$ mesons can be produced, with their spins aligned up to J=6, and how these states found theoretically can be associated to several known mesons with spins J=2,3,4,5,6.Comment: Talk at the 21st European Conference on Few Body Problems in Physics, Salamanca, Sep. 201

Efectos de un programa de actividad física con el método pilates sobre la funcionalidad de mujeres embarazadas. Estudio piloto

This study aims to determine the effect of a Pilates programme on functionality in pregnant women; and to analyse its impact on childbirth. A group of 10 pregnant women developed a Pilates program for 8 weeks (2 sessions/week), overall functionality was assessed through functional tests Overhead Squat (OHS), Hurdle Step (HS), Forward Step Down (FSD), Shoulder Mobility (SM) and Active Straight Leg Raise (ASLR), as well as the type of subsequent delivery. The results show an improvement in the functionality of the Hurdle test; Forward step down and Shoulder mobility test (p<0.01), as well as a significant decrease in compensation and overall risk of injury after the physical activity programme (p<0.01). In turn, the delivery was healthier. The effects of Pilates on pregnant women offer improvements in overall functionality and a positive effect on childbirth.El presente estudio pretende determinar el efecto de un programa de Pilates sobre la funcionalidad en mujeres gestantes y analizar su repercusión en el parto.

Probing canonical geometrical objects by digital spiral imaging

We recently proposed a novel concept to remotely acquire information of objects, based on the discrete orbital angular momentum of ligh. Here we use two different experimental schemes for implementing the technique. We use a canonical phase jump as a target to test the methods and to compare the results

Study of the f2(1270)f_2(1270), f2′(1525)f_2'(1525), f0(1370)f_0(1370) and f0(1710)f_0(1710) in the J/ψJ/\psi radiative decays

In this paper we present an approach to study the radiative decay modes of the $J/\psi$ into a photon and one of the tensor mesons $f_2(1270)$, $f'_2(1525)$, as well as the scalar ones $f_0(1370)$ and $f_0(1710)$. Especially we compare predictions that emerge from a scheme where the states appear dynamically in the solution of vector meson--vector meson scattering amplitudes to those from a (admittedly naive) quark model. We provide evidence that it might be possible to distinguish amongst the two scenarios, once improved data are available.Comment: The large Nc argument improved; version published in EPJA

Triggered qutrits for Quantum Communication protocols

A general protocol in Quantum Information and Communication relies in the ability of producing, transmitting and reconstructing, in general, qunits. In this letter we show for the first time the experimental implementation of these three basic steps on a pure state in a three dimensional space, by means of the orbital angular momentum of the photons. The reconstruction of the qutrit is performed with tomographic techniques and a Maximum-Likelihood estimation method. In this way we also demonstrate that we can perform any transformation in the three dimensional space

An Experimental Investigation of the Adsorption of a Phosphonic Acid on the Anatase TiO2(101) Surface

A combination of synchrotron radiation photoelectron spectroscopy and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy has been used to study the adsorption of phenylphosphonic acid (PPA) on anatase TiO2(101) single crystal at coverages of 0.15 monolayer (ML) and 0.85 ML. The photoelectron spectroscopy data suggest that at 0.15 ML coverage PPA adsorbs in a bidentate geometry following deprotonation of both phosphonate hydroxyl groups, leaving the P═O group unbound. At 0.85 ML there is a shift to a mixed bidentate/monodentate binding mode. The carbon K-edge NEXAFS spectra were recorded at two azimuths. Our calculations show that for PPA on anatase TiO2(101) the phenyl ring is oriented 65 ± 4° away from the surface plane with an azimuthal twist of 57 ± 11° away from the [101] azimuth

Efectos del daño de la mosca del olivo y del atroje sobre la microflora en pasta y la acidez del aceite virgen de oliva

The effects of olive fly damage, olive storage, harvest date, olive grove plot and their interactions on the microflora associated with olive paste and oil acidity were studied. Microflora and oil acidity were significantly affected by the four studied factors and by several interactions between them. Fly damage and olive storage interacted sinergically increasing oil acidity. The relationship between fly damage and oil acidity was lineal although sometimes it was not significant depending on microflora populations. The relationship between microflora populations and oil acidity fitted to a logarithmic model. Major microorganisms in olive paste were bacteria (Xanthomonas), yeasts (mostly Torulopsis and Candida) and in a smaller measure moulds (mainly Fusarium and Penicillium). Results overall suggest that a qualitative damage threshold based on the percentage of damaged fruits in order to infer oil acidity may be unfeasible in most instances.Se estudiaron los efectos del daño de mosca, atroje, fecha de recolección, parcela de olivo y de sus interacciones, sobre la microflora asociada a la pasta de aceituna y la acidez del aceite obtenido. Microflora y acidez se vieron significativamente afectados por los cuatro factores estudiados y por varias de sus interacciones. Daño y atroje interactuaron sinérgicamente para incrementar la acidez. La relación entre el daño de mosca y la acidez fue lineal aunque a veces no fue significativa dependiendo de la microflora. La relación entre la microflora y la acidez se ajustó a un modelo logarítmico. Los microorganismos predominantes en la pasta fueron bacterias (Xanthomonas), levaduras (fundamentalmente Torulopsis y Candida) y en menor medida otros hongos (principalmente Fusarium y Penicillium). Los resultados sugieren que un umbral de daño cualitativo basado en el porcentaje de frutos picados para inferir la acidez del aceite es de difícil implementación
