Objective Competitiveness Ranking amongst EU Regions (Objective Method for Quantifying Regional Competitiveness - a case study applied to EU15 Regions)

Nowadays the key target of Cohesion Policy is to promote the creation of conditions to improve the growth, and to increase the factors that lead to a real convergence (Economic and Social Cohesion). An important group of these factors is found when considering the competitivity of a Region that implies, (even whitout existintg a clear definition), to consider at the same time two different levels: - The first one through the specific factors to improve the development of the resident managerial weave (Innovation, Research & Development, enterprises nets, labour market, training, support in the use of new technologies, servicies to entreprises, etc.). – The second one, improving the enviromental conditions for the development of such an managerial activity (Transport and comunication infrastructures, environment and sustainable developpment ,use of renewable energies, etc.) The objetcive of the present paper is to propose an objective way to consider the totalitiy of factors simultaneously, in order to obtain a ranking of the of the regional competitivity, and to study his changes in the time. For this, it will be used the data base “REGIO” and techniques of ranking belonging to multicriteria decision making. The analyzed period is from 1987 to 2002 which shows interesting results mainly when compared with other analyses carried out.

Kaleidoscope of exotic quantum phases in a frustrated XY model

The existence of quantum spin liquids was first conjectured by Pomeranchuk some 70 years ago, who argued that frustration in simple antiferromagnetic theories could result in a Fermi-liquid-like state for spinon excitations. Here we show that a simple quantum spin model on a honeycomb lattice hosts the long sought for Bose metal with a clearly identifiable Bose surface. The complete phase diagram of the model is determined via exact diagonalization and is shown to include four distinct phases separated by three quantum phase transitions

Short-Range Correlations and Cooling of Ultracold Fermions in the Honeycomb Lattice

We use determinantal quantum Monte Carlo simulations and numerical linked-cluster expansions to study thermodynamic properties and short-range spin correlations of fermions in the honeycomb lattice. We find that, at half filling and finite temperatures, nearest-neighbor spin correlations can be stronger in this lattice than in the square lattice, even in regimes where the ground state in the former is a semimetal or a spin liquid. The honeycomb lattice also exhibits a more pronounced anomalous region in the double occupancy that leads to stronger adiabatic cooling than in the square lattice. We discuss the implications of these findings for optical lattice experiments.Comment: 5 pages, 4 figure

Regional cohesion in the EU: An analysis using the Lisbon index approach

El Índice Regional de Lisboa (IRL) cuantifica la cohesión y sintetiza en un solo valor la distancia de las regiones europeas respecto a los objetivos de la Estrategia de Lisboa, así como la distancia existente entre ellas. El IRL se ha calculado para 265 regiones con información procedente de Eurostat sobre el mercado laboral, la formación y el gasto en I+D+i en el periodo 2000-2010. Los resultados muestran que en la EU-27 se consiguió mejorar la situación de las regiones hasta 2007, pero la crisis ha producido un aumento de las desigualdades, situación de la que no escapan las regiones españolas.The Regional Lisbon Index (RLI) quantifies cohesion and summarizes into a single value the distance of European regions to the objectives of the Lisbon Strategy and the distance between them. The RLI has been calculated for 265 European NUTS2 with information from Eurostat on the labor market, training and R & D, in the period 2000-2010. Results show that the regional situation improved up in the EU-27 to 2007, but the crisis has been an increased in inequality, a situation that also occurs in the Spanish regions.Publishe

Replacing the Transfusion of 1-2 Units of Blood with Plasma Expanders that Increase Oxygen Delivery Capacity: Evidence from Experimental Studies.

At least a third of the blood supply in the world is used to transfuse 1-2 units of packed red blood cells for each intervention and most clinical trials of blood substitutes have been carried out at this level of oxygen carrying capacity (OCC) restoration. However, the increase of oxygenation achieved is marginal or none at all for molecular hemoglobin (Hb) products, due to their lingering vasoactivity. This has provided the impetus for the development of "oxygen therapeutics" using Hb-based molecules that have high oxygen affinity and target delivery of oxygen to anoxic areas. However it is still unclear how these oxygen carriers counteract or mitigate the functional effects of anemia due to obstruction, vasoconstriction and under-perfusion. Indeed, they are administered as a low dosage/low volume therapeutic Hb (subsequently further diluted in the circulatory pool) and hence induce extremely small OCC changes. Hyperviscous plasma expanders provide an alternative to oxygen therapeutics by increasing the oxygen delivery capacity (ODC); in anemia they induce supra-perfusion and increase tissue perfusion (flow) by as much as 50%. Polyethylene glycol conjugate albumin (PEG-Alb) accomplishes this by enhancing the shear thinning behavior of diluted blood, which increases microvascular endothelial shear stress, causes vasodilation and lowering peripheral vascular resistance thus facilitating cardiac function. Induction of supra-perfusion takes advantage of the fact that ODC is the product of OCC and blood flow and hence can be maintained by increasing either or both. Animal studies suggest that this approach may save a considerable fraction of the blood supply. It has an additional benefit of enhancing tissue clearance of toxic metabolites

Influence of serological factors and BMI on the blood pressure/hematocrit association in healthy young men and women.

The association between mean arterial blood pressure (MAP) and hematocrit (Hct) as a surrogate for blood viscosity was investigated in a young (average 20.0±2.3 years), healthy population of 174 men and 442 women. Health status was assessed by clinical examination and serological evaluation. Individuals with severe anemia or hemoconcentration, prior traumas or major surgical intervention, smokers, and pregnant or lactating women were excluded from the study. The MAP/Hct association was positive and significant (P=0.04) for women and negative, albeit not significantly so, for men. The MAP/Hct association was also evaluated in subgroups of the same population with a progressive step-by-step exclusion of: individuals with cholesterol >200 mg/dL; triglycerides >200 mg/dL; body mass index >25 kg/m(2); and glucose >100 mg/dL. This consecutively reduced the strength of the positive MAP/Hct association in women, which became negative - although not significantly so - when all anomalously high factors were excluded. The same trend was found in men. Our study indicates that previously reported positive trends in the relationship between the MAP and Hct in the population are not present in a young, healthy population of men or women that excludes individuals with the confounding factors of above normal serological values and BMI

Tunneling effects on impurity spectral function in coupled asymmetric quantum wires

The impurity spectral function is studied in coupled double quantum wires at finite temperatures. Simple anisotropy in the confinement direction of the wires leads to finite non-diagonal elements of the impurity spectral function matrix. These non-diagonal elements are responsible for tunneling effects and result in pronounced extra peak in the impurity spectral function up to temperatures as high as 20 K.Comment: Accepted in Phys.
