Quasi-Lie Brackets and the Breaking of Time-Translation Symmetry for Quantum Systems Embedded in Classical Baths
2018
Many open quantum systems encountered in both natural and synthetic situations are embedded in classical-like baths. Often, the bath degrees of freedom may be represented in terms of canonically conjugate coordinates, but in some cases they may require a non-canonical or non-Hamiltonian representation. Herein, we review an approach to the dynamics and statistical mechanics of quantum subsystems embedded in either non-canonical or non-Hamiltonian classical-like baths which is based on operator-valued quasi-probability functions. These functions typically evolve through the action of quasi-Lie brackets and their associated Quantum-Classical Liouville Equations, or through quasi-Lie brackets a…
Guinean and sahelian rainfall anomaly indices at annual and monthly scales (1933-1990)
1994
The annual and monthly rainfall variability in north tropical Africa are analysed by principal component analysis in order to detect the main coherent modes. The Sahel constitutes the first mode, although it is divided close to 1O"W into an Atlantic section and a Continental section. The Guinean zone is less coherent, and is divided into distinct modes. The subequatorial area never formed a distinct mode. Rainfall variability for the coherent areas is constructed from rainfall anomaly indices (RAI), based on the coherent areas, and a rainfall typology taking into account the spatial pattern of the rainfall anomaly fields and the intensity of the anomaly. Their evolution (mainly since 1950) …
Acting under the idea of freedom: Kant and the Incorporation Thesis
2010
Este artículo examina un supuesto fundamental de la filosofía moral kantiana, a saber: que sin libertad trascendental, entendida como la propiedad de la voluntad por la que se determina a actuar sin ser afectada por resortes sensibles, no se le pueden imputar al presunto agente actos inmorales. Teóricamente se argumenta contra el sentido lógico del supuesto (se revela la consecuencia aporética de la concepción) y se muestra cuán superfluo es en la práctica. De todos modos, se le reconoce a Kant, contra una línea de argumentación nietzscheana bien conocida, el mérito de haber captado el compromiso humano insuperable con la idea de que somos seres discrecionales o libres trascendentalmente. Y…
Quantized Fields and Their Interpretation
2013
This chapter deals with the quantum theory of systems with an infinite number of degrees of freedom and provides elements of quantum field theory.
Public health as a limit to the right to scientific research in the case of vaccines
2022
El auge del movimiento antivacunas en general, y las investigaciones y publicaciones científicas que desacreditan la vacunación en particular, representan una seria amenaza para la salud pública. Puesto que en nombre de estaúltima pueden limitarse derechos y libertades fundamentales, podría pensarse que, en nombre de la salud pública, podría limitarse también la investigación y difusión de material científico que cuestione la práctica de la vacunación. El objetivo de este artículo será comprobar si esa hipótesis es compatible con el actual régimen de derechos y libertades, y señalar el mejor modo de hacerfrente al discurso antivacunas. The boom of the anti-vaccine movement in general, and s…
Remark on integrable Hamiltonian systems
1980
An extension ton degrees of freedom of the fact is established that forn=1 the time and the energy constant are canonically conjugate variables. This extension is useful in some cases to get action-angle variables from the general solution of a given integrable Hamiltonian system. As an example the Delaunay variables are proved to be canonical.

The Economics of Freedom. Theory, Measure and Policy Implications
2012
What is freedom? Can we measure it? Does it affect policy? This book develops an original measure of freedom called 'Autonomy Freedom', consistent with J. S. Mill's view of autonomy, and applies it to issues in policy and political design. The work pursues three aims. First, it extends classical liberalism beyond exclusive reliance on negative freedom so as to take autonomous behavior explicitly into account. Second, it grounds on firm conceptual foundations a new standard in the measurement of freedom that can be fruitfully coupled with existing gauges. Third, it shows empirically that individual preferences for redistribution and cross-country differences in welfare spending in Organisati…
Use of a running coupling in the NLO calculation of forward hadron production
2018
We address and solve a puzzle raised by a recent calculation [1] of the cross-section for particle production in proton-nucleus collisions to next-to-leading order: the numerical results show an un- reasonably large dependence upon the choice of a prescription for the QCD running coupling, which spoils the predictive power of the calculation. Specifically, the results obtained with a prescription formulated in the transverse coordinate space differ by one to two orders of magnitude from those obtained with a prescription in momentum space. We show that this discrepancy is an artefact of the interplay between the asymptotic freedom of QCD and the Fourier transform from coordinate space to mo…
Current caselaw discrepancies in the protection of national symbols and state representatives between the European Court of Human Rights and Spanish …
2021
Despite the general consensus about freedom of expression being a basic fundamental right on every democratic society, the debate about its boundaries has never found such a pacific agreement. Thus, the Spanish Penal Code has several articles that punish its abuse that are highly contested, like articles 490.3 and 543 that penalize the offenses directed towards national symbols or State representatives. This being so, this article examines the controversy generated by the application of this articles through the analysis of two judgements issued by the European Court of Human Rights against Spain, and a third one issued by the Spanish Constitutional Court that could follow the same path. Th…
