Contractive metrics for a Boltzmann equation for granular gases: diffusive equilibriaThe Patterson-Sullivan embedding and minimal volume entropy for outer space

We quantify the long-time behavior of a system of (partially) inelastic particles in a stochastic thermostat by means of the contractivity of a suitable metric in the set of probability measures. Existence, uniqueness, boundedness of moments and regularity of a steady state are derived from this basic property. The solutions of the kinetic model are proved to converge exponentially as t→ ∞ to this diffusive equilibrium in this distance metrizing the weak convergence of measures. Then, we prove a uniform bound in time on Sobolev norms of the solution, provided the initial data has a finite norm in the corresponding Sobolev space. These results are then combined, using interpolation inequalities, to obtain exponential convergence to the diffusive equilibrium in the strong L¹-norm, as well as various Sobolev norms.

Estudio Farmacogenético en Pacientes con Cáncer de Pulmón No Microcítico Avanzado tratados con Quimioterapia basada en Platino

a partir de ADN genómico obtenido de las células nucleadas de sangre periférica de 103 pacientes con Cáncer de Pulmón No Microcítico (CPNM) avanzado tratados con quimioterapia basada en platino, hemos analizado la asociación entre supervivencia y cinco SNPs (Single Nucleotide Polymorphism) pertenecientes a dos grupos de genes: i) de la via metabólica del ácido fólico (Timidilato Sintetasa (TS), Metil-tetrahidrofolato Reductasa (MTHFR) y, ii) de la vía de reparación del ADN (Excision repair cross-complemeting group 1 (ERCC1) y Xeroderma pigmentosum group D (XPD).

Escenarios del impacto de la inmigración en la longevidad y dependencia de los mayores en la población española

Introduction: The composition of the Spanish population has recently changed due to immigration. The present study aimed to estimate the magnitude of change in the calculation of healthy life expectancy and life expectancy in disability, taking the population of foreign residents into account. For this population, there is no information on mortality or the prevalence of disability. Material and methods: Data were extracted from the 1999 Survey on Disabilities, Handicaps and Health Status to estimate healthy life expectancy and life expectancy in disability using the Sullivan method. Data were taken from the Spanish Statistical Institute and the World Health Organization, Sullivan's method was adapted to the case of two different populations, and possible scenarios were established. Results: The differences between the mortality table estimated for the foreign resident population and that estimated for the Spanish population were considerable and were more evident in women. At 65 years of age and in the worst scenario, which occurs when all the members of the foreign resident population are disabled, life expectancy in disability would be 2 more years for men and 3 more years for women than when the foreign population was not considered. Conclusions: Our scenarios reveal that the impact of immigration on the calculation of healthy life expectancy and life expectancy in disability is moderate.

$E_{1}$-Formality of complex algebraic varieties

Let $X$ be a smooth complex algebraic variety. Morgan showed that the rational homotopy type of $X$ is a formal consequence of the differential graded algebra defined by the first term $E_{1}(X,W)$ of its weight spectral sequence. In the present work, we generalize this result to arbitrary nilpotent complex algebraic varieties (possibly singular and/or non-compact) and to algebraic morphisms between them. In particular, our results generalize the formality theorem of Deligne, Griffiths, Morgan and Sullivan for morphisms of compact Kähler varieties, filling a gap in Morgan"s theory concerning functoriality over the rationals. As an application, we study the Hopf invariant of certain algebraic morphisms using intersection theory.
