La declaración unilateral de independencia de Kosovo a la luz de la Opinión Consultiva de la Corte Internacional de Justicia, de 22 de julio de 2010 y de las declaraciones, opiniones individuales y disidentes a la misma

The Opinion of the International Court of Justice on the unilateral declaration of independence of Kosovo is an example of what the Court should not do. Saying only that international law does not prohibit declarations of independence and refusing to answer the matters related to this claim, the Court's opinion adopts a vacuum of legal terms and irresponsible

The Possible White Dwarf-Neutron Star Connection

The current status of the problem of whether neutron stars can form, in close binary systems, by accretion-induced collapse (AIC) of white dwarfs is examined. We find that, in principle, both initially cold C+O white dwarfs in the high-mass tail of their mass distribution in binaries and O+Ne+Mg white dwarfs can produce neutron stars. Which fractions of neutron stars in different types of binaries (or descendants from binaries) might originate from this process remains uncertain.Comment: 6 pages. To appear in "White Dwarfs", ed.

Quantum Interference in Single Molecule Electronic Systems

We present a general analytical formula and an ab initio study of quantum interference in multi-branch molecules. Ab initio calculations are used to investigate quantum interference in a benzene-1,2-dithiolate (BDT) molecule sandwiched between gold electrodes and through oligoynes of various lengths. We show that when a point charge is located in the plane of a BDT molecule and its position varied, the electrical conductance exhibits a clear interference effect, whereas when the charge approaches a BDT molecule along a line normal to the plane of the molecule and passing through the centre of the phenyl ring, interference effects are negligible. In the case of olygoynes, quantum interference leads to the appearance of a critical energy $E_c$, at which the electron transmission coefficient $T(E)$ of chains with even or odd numbers of atoms is independent of length. To illustrate the underlying physics, we derive a general analytical formula for electron transport through multi-branch structures and demonstrate the versatility of the formula by comparing it with the above ab-initio simulations. We also employ the analytical formula to investigate the current inside the molecule and demonstrate that large counter currents can occur within a ring-like molecule such as BDT, when the point charge is located in the plane of the molecule. The formula can be used to describe quantum interference and Fano resonances in structures with branches containing arbitrary elastic scattering regions connected to nodal sites.Comment: 12 pages, 11 figure

Evaluación de la severidad de la incontinencia urinaria de esfuerzo con estudios urodinámicos: un estudio comparativo para detectar deficiencia intrínseca del esfínter uretral externo

ResumenObjetivoDeterminar la sensibilidad y especificidad del punto de presión de fuga abdominal (ALPP), para evaluar la presencia de deficiencia intrínseca del esfínter (DIE) comparativamente con la presión máxima de cierre uretral (MUCP, por sus siglas en inglés), estableciendo la correlación clínico-urodinámica correspondiente.ResultadosFueron evaluadas 34 pacientes con incontinencia urinaria de esfuerzo (IUE); 17 paciente (50%) fueron diagnosticadas urodinámicamente con DIE por punto de ALPP; 9 tuvieron IUE severa mientras que sólo 2 (5.8%) lo fueron por MUCP, de las cuales una tuvo IUE severa y otra, IUE moderada. Dieciocho pacientes fueron catalogadas clínicamente como IUE severa, de las cuales 17 tuvieron DIE por ALPP entre severa y moderada (94%).ConclusionesLa evaluación urodinámica de la IUE permite establecer de manera clara la fisiopatología de una disfunción del tracto urinario inferior concomitante, con la posibilidad de objetivar la presencia de IUE con el ALPP en al menos 85% de los casos, con una sensibilidad y especificidad para diagnosticar DIE muy superior a la MUCP.AbstractAimsTo determine the sensitivity and specificity of the abdominal leak point pressure (ALPP) in order to comparatively evalúate the presence of intrinsic sphincter deficiency (ISD) with máximum urethral closure pressure (MUCP) and establish the corresponding clinical and urodynamic correlation.ResultsThirty-four patients with stress urinary incontinence (SUI) were evaluated. Seventeen of those patients (50%) were urodynamically diagnosed with ISD through ALPP and 9 of them had severe SUI. Only 2 patients were diagnosed with ISD through MUCP; one of them had severe SUI and the other presented with modérate SUI. Eighteen patients were clinically classified with severe SUI, 17 of whom had moderate to severe ISD diagnosed through ALPP (94%).ConclusionsUrodynamic evaluation of SUI made it possible to clearly establish the pathophysiology of concomitant lower urinary tract dysfunction and to objectify the presence of SUI through ALPP in at least 85% of the cases. ALPP had a much higher sensitivity and specificity for diagnosing ISD than MUCP

Future trends of snowfall days in northern Spain from ENSEMBLES regional climate projections

In a previous study Pons et al. (Clim Res 54(3):197-207, 2010. doi:10.3354/cr01117g) reported a significant decreasing trend of snowfall occurrence in the Northern Iberian Peninsula since the mid 70s. The study was based on observations of annual snowfall frequency (measured as the annual number of snowfall days NSD) from a network of 33 stations ranging from 60 to 1350 m. In the present work we analyze the skill of Regional Climate Models (RCMs) to reproduce this trend for the period 1961-2000 (using both reanalysis- and historical GCM-driven boundary conditions) and the trend and the associated uncertainty of the regional future projections obtained under the A1B scenario for the first half of the twenty-first century. In particular, we consider the regional simulation dataset from the EU-funded ENSEMBLES project, consisting of thirteen state-of-the-art RCMs run at 25 km resolution over Europe. While ERA40 severely underestimates both the mean NSD and its observed trend (-2.2 days/decade), the corresponding RCM simulations driven by the reanalysis appropriately capture the interannual variability and trends of the observed NSD (trends ranging from -3.4 to -0.7, -2.1 days/decade for the ensemble mean). The results driven by the GCM historical runs are quite variable, with trends ranging from -8.5 to 0.2 days/decade (-1.5 days/decade for the ensemble mean), and the greatest uncertainty by far being associated with the particular GCM used. Finally, the trends for the future 2011-2050 A1B runs are more consistent and significant, ranging in this case from -3.7 to -0.5 days/decade (-2.0 days/decade for the ensemble mean), indicating a future significant decreasing trend. These trends are mainly determined by the increasing temperatures, as indicated by the interannual correlation between temperature and NSD (-0.63 in the observations), which is preserved in both ERA40- and GCM-driven simulations.This research has received funding from the European Union’s Seventh Framework Programme under Grant Agreements 606799 (INTACT Project). The RCM simulations used in this study were obtained from the European Union-funded FP6 Integrated Project ENSEMBLES (Contract No. 505539)
