Soleares Trianeras. Recuperación de una zarzuela de Emigdio Mariani

Este trabajo supone el redescubrimiento de una zarzuela, Soleares Trianeras, compuesta y estrenada por Emigdio Mariani en 1930, de la que conservo posiblemente la única copia, tanto del libreto como de la música. La obra, anclada en el espacio y tiempo, responde a la tipología de los espectáculos convencionales de la Sevilla más tradicional de su época y más que un interés innovador (todo en ella es conservador), contiene la valía de ser una fuente directa para acercarnos a una parte importante de la mentalidad sevillana del momento, tan localista y lejana de las propuestas musicales más vanguardistas que se desarrollaban en otras ciudades españolas y europeas

Linear hydrodynamics for driven granular gases

We study the dynamics of a granular gas heated by a stochastic thermostat. From a Boltzmann description, we derive the hydrodynamic equations for small perturbations around the stationary state that is reached in the long time limit. Transport coefficients are identified as Green-Kubo formulas obtaining explicit expressions as a function of the inelasticity and the spatial dimensio

Methods for causality assessment of idiosyncratic drug-induced liver injury

The diagnosis of idiosyncratic drug-induced liver injury (DILI) is a challenging task due to the lack of specific features or definitive diagnostic tools. A minimum of clinical and pharmacological information is required, together with laboratory and imaging tests to exclude other causes of liver injury. Several standardized methods have been developed to support clinical judgement and establish causality assessment, the most widely used being the Roussel Uclaf Causality Assessment Method—RUCAM— and structured Expert Opinion. More recently, an evidence-based, revised RUCAM, Electronic Causality Assessment Method—RECAM—has been developed and, although still a work in progress, may replace RUCAM scoring in the future. International collaborative networks and ongoing research efforts are key to advancing biomarker qualification and validation and developing new in vitro patient-based methods that will help improve DILI diagnosis and move towards a personalized medicine approach.Funding for open access charge: Universidad de Málaga / CBUA.

Energy fluctuations in a randomly driven granular fluid

We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is derived and the hydrodynamic eigenvalues are identified. Explicit predictions are subsequently determined for energy fluctuations. The results explain Monte Carlo numerical data reported in previous studies [Eur. Phys. J. B 51, 377 (2006)].Agence Nationale de la Recherche ANR-05-JCJC-4448

Brownian motion under annihilation dynamics

The behavior of a heavy tagged intruder immersed in a bath of particles evolving under ballistic annihilation dynamics is investigated. The Fokker-Planck equation for this system is derived and the peculiarities of the corresponding diffusive behavior are worked out. In the long time limit, the intruder velocity distribution function approaches a Gaussian form, but with a different temperature from its bath counterpart. As a consequence of the continuous decay of particles in the bath, the mean-squared displacement increases exponentially in the collision per particle time scale. Analytical results are finally successfully tested against Monte Carlo numerical simulations.HPC-EUROPA project No. RII3-CT-2003-50607

Kinetic equation and nonequilibrium entropy for a quasi-two-dimensional gas

A kinetic equation for a dilute gas of hard spheres confined between two parallel plates separated a distance smaller than two particle diameters is derived. It is a Boltzmann-like equation, which incorporates the effect of the confinement on the particle collisions. A function S(t) is constructed by adding to the Boltzmann expression a confinement contribution. Then it is shown that for the solutions of the kinetic equation, S(t) increases monotonically in time, until the system reaches a stationary inhomogeneous state, when S becomes the equilibrium entropy of the confined system as derived from equilibrium statistical mechanics. From the entropy, other equilibrium properties are obtained, and molecular dynamics simulations are used to verify some of the theoretical predictions.España Mineco Grant No. FIS2014-53808-

Homogeneous dynamics in a vibrated granular monolayer

A simple model of a vibrated granular monolayer is studied. It consists of inelastic hard spheres confined between two parallel hard plates separated at a distance smaller than twice the diameter of the particles. Both walls are elastic and one of them is vibrating in a sawtooth way. For low densities, a kinetic equation is proposed, from which closed evolution equations for the horizontal and vertical temperatures are derived, assuming spatial homogeneity and that the system is very thin. An excellent agreement between the theoretical predictions and molecular dynamics simulation results is obtained, both for the stationary values and for the dynamics of the temperatures.Ministerio de Economía, Industria y Competitividad FIS2017-87117-
