ChPT parameters from tau-decay data

Using the updated ALEPH V-A spectral function from tau decays, we determine the lowest spectral moments of the left-right correlator and extract dynamical information on order parameters of the QCD chiral symmetry breaking. Uncertainties associated with violations of quark-hadron duality are estimated from the data, imposing all known short-distance constraints on a resonance-based parametrization. Employing proper pinched weight functions, we obtain an accurate determination of the effective chiral couplings L10 and C87 and the dimension-six and -eight contributions in the Operator Product Expansion.Comment: 5 pages, 3 figures, QCD2015 Montpellie

Making Sustainable Agriculture Real in CAP 2020: The Role of Conservation Agriculture

Europe is about to redefine its Common Agriculture Policy (CAP) for the near future. The question is whether this redefinition is more a fine-tuning of the existing CAP or whether thorough changes can be expected. Looking back to the last revision of CAP the most notable change is, undoubtedly, the concern about EU and global food security. The revival of the interest in agricultural production already became evident during the Health Check as a consequence of climbing commodity prices in 2007/08. It is therefore no surprise that “rising concerns regarding both EU and global food security” is the first topic to appear in the list of justifications for the need for a CAP reform. Other challenges mentioned in this list such as sustainable management of natural resources, climate change and its mitigation, improvement of competitiveness to withstand globalization and rising price volatility, etc., while not new are considered worthwhile enough to be maintained and reappraised

Hausdorff dimension in RR-analytic profinite groups

We study the Hausdorff dimension of R-analytic subgroups in an R-analytic profinite group, where R is a pro-p ring whose asso- ciated graded ring is an integral domain. In particular, we prove that the set of such Hausdorff dimensions is a finite subset of the rational numbers.Comment: 7 page

Improving a Satellite Mission System by means of a Semantic Grid Architecture

The use of a semantic grid architecture can make easier the deployment of complex applications, in which several organizations are involved and diverse resources are shared. This paper presents the application of the architecture defined in the Ontogrid project (S-OGSA) into a scenario for the analysis of the quality of the products of satellite missions

Simulation Platform for Coordinated Charging of Electric Vehicles

EMERALD is a project funded by the European Commission under the FP7 program focusing on energy use optimization on the integration of the FEVs into the transport and energy infrastructure. Between the objectives of EMERALD, enhanced power demand prediction and power flow support management system uses the power flow demand simulation platform considered in this paper. The power flow demand simulation platform is a software tool that defines the estimation of FEVs power demand according to different conditions as, arrival and departure curves, the estimation of power production based on renewable energy sources and the electricity cost. The tool coordinates scheduling for charging of FEVs in order to minimize the recharging cost, considering the energy balance between the generation and demand powerEuropean commission's FP

Cooperative Simulation Tool with the Energy Management System for the Storage of Electricity Surplus through Hydrogen

The INGRID project aims at demonstrating the effective usage of safe, high-density, solid-state hydrogen storage systems for power supply and demand balancing within active power distribution grids with high penetration of intermittent Distributed Generation (Renewable Energy Sources in particular.) The INGRID simulator is divided in two main blocks: the first one represents the Energy Management System, the second one includes the Green Energy Storage System (water electrolyzer, hydrogen solid-storage systems and fuel cell) created to simulate the plant. This paper describes the modules of INGRID simulator and the transient responses of the system for an energy management system virtual according to the power prediction of renewable energy sources, hydrogen demand and the power demand of electric vehiclesEuropean Commission's FP

Preferences of young consumers for joints obtained from the technological division of the rabbit carcass evaluated by photographic images

Una muestra de 405 jóvenes de Andalucía, con edades comprendidas entre 18 y 32 años y con un 54,3% de mujeres, se sometió a dos pruebas de valoración de fotografías con la finalidad de conocer, por una parte, su preferencia entre las piezas pata trasera, pata delantera, pieza lomo y caja torácica procedentes del despiece tecnológico de la canal de conejo y, por otra parte, su preferencia entre la pieza lomo y las chuletas de lomo obtenidas de esta pieza por sección transversal al raquis. En la primera prueba el orden de preferencia, de mayor a menor atractivo, fue la pata trasera, la pieza lomo, la pata delantera y la caja torácica (P<0,001) tanto en hombres como en mujeres y si eran o no consumidores de carne de conejo. En la segunda prueba la pieza lomo fue mejor valorada que las chuletas de lomo (P<0,001) por el conjunto de los sujetos de la muestra, por ambos sexos y por los jóvenes que consumían carne de conejo, mientras que los no consumidores de carne de conejo no mostraron diferencias de valoración entre ambas presentaciones (P>0,05). Los resultados ilustran la mayor aceptación que pueden tener para los consumidores las piezas de la canal con mayor cantidad de carne, sugiriéndose que estas diferencias de preferencia entre piezas de la canal podrían influir en eventuales decisiones de compra de despieces de carne de conejo.A sample of 405 young people from Andalusia (Spain), aged between 18 and 32 years and 54.3% of women was subjected to two tests consisting in scoring of photographic images in order to study i) their preference among hind leg, fore leg, loin and thoracic cage joints obtained from the technological division of the rabbit carcass, and ii) their preference between the loin joint and loin chops obtained by transverse cutting of the raquis. In the first test the decreasing degree of preference was the hind leg, the loin joint, the fore leg and the thoracic cage (P <0.001) in both men and women and whether they were rabbit meat consumer or not. In the second test loin joint reached higher score than loin chops (P <0.001) for all the individuals in the sample, for both sexes and for young people who consume rabbit meat, while non rabbit meat consumers showed no difference in preference between the two presentations (P> 0.05). The results illustrate the higher acceptance that young consumers may show for joints of the carcass with higher meat content, this suggesting that differences in preference among carcass joints could influence any decisions to purchase cuts of rabbit meat
