Octopus, a computational framework for exploring light-driven phenomena and quantum dynamics in extended and finite systems
2020
Over the last few years, extraordinary advances in experimental and theoretical tools have allowed us to monitor and control matter at short time and atomic scales with a high degree of precision. An appealing and challenging route toward engineering materials with tailored properties is to find ways to design or selectively manipulate materials, especially at the quantum level. To this end, having a state-of-the-art ab initio computer simulation tool that enables a reliable and accurate simulation of light-induced changes in the physical and chemical properties of complex systems is of utmost importance. The first principles real-space-based Octopus project was born with that idea in mind,…

A Stieltjes Approach to Static Hedges
2014
Static hedging of complicated payoff structures by standard instruments becomes increasingly popular in finance. The classical approach is developed for quite regular functions, while for less regular cases, generalized functions and approximation arguments are used. In this note, we discuss the regularity conditions in the classical decomposition formula due to P. Carr and D. Madan (in Jarrow ed, Volatility, pp. 417–427, Risk Publ., London, 1998) if the integrals in this formula are interpreted as Lebesgue integrals with respect to the Lebesgue measure. Furthermore, we show that if we replace these integrals by Lebesgue–Stieltjes integrals, the family of representable functions can be exte…
Isometries between spaces of multiple Dirichlet series
2019
Abstract In this paper we study spaces of multiple Dirichlet series and their properties. We set the ground of the theory of multiple Dirichlet series and define the spaces H ∞ ( C + k ) , k ∈ N , of convergent and bounded multiple Dirichlet series on C + k . We give a representation for these Banach spaces and prove that they are all isometrically isomorphic, independently of the dimension. The analogous result for A ( C + k ) , k ∈ N , which are the spaces of multiple Dirichlet series that are convergent on C + k and define uniformly continuous functions, is obtained.

Este trabajo pretende reflexionar sobre las implicaciones educativas que hoy día tiene la competencia mediática en los procesos de enseñanza-aprendizaje. La evolución de las TIC y, sobre todo, de la tecnología móvil, ha provocado una revolución comunicativa educativa y social que afecta al mundo educativo; los contextos edu-cativos son cambiantes y evolucionan rápido, teniendo que adaptarse a los cambios socioculturales, tecnológi-cos, et…
Incremento della temperatura lungo la superficie radicolare durante la tecnica dell’onda continua di condensazione
2008
INTRODUZIONE: Le temperature raggiunte degli strumenti portatori di calore, durante la condensazione a caldo della guttaperca, sono molto elevate. Ciò potrebbe rappresentare una fonte di danno iatrogeno a livello delle strutture parodontali sottoposte ad un eccessivo stress termico. SCOPO DEL LAVORO: Valutazione termografica a infrarossi dell’incremento della temperatura lungo la superficie radicolare, durante la tecnica dell’onda continua di condensazione. MATERIALI E METODI: Venti incisivi laterali mascellari, estratti per motivi parodontali, sono stati selezionati e alesati con M-two. In tutti i campioni è stata eseguita un’otturazione canalare mediante coni di guttaperca non standardizz…
Terapia electroconvulsiva de continuación/mantenimiento como estabilizador del ánimo: Estudio de cohorte retrospectivo en espejo de un periodo de 23 …
2021
La terapia electroconvulsiva (TEC) es un tratamiento eficaz y seguro, tanto en la depresión unipolar como en la bipolar, así como en la manía fármacorresistente. Sin embargo, su efecto es limitado en el tiempo, ya que las tasas de recaída y recurrencia en el primer año son elevadas, de hasta el 50-60%. Estas se van a producir fundamentalmente en los primeros 6 meses tras la interrupción del tratamiento con TEC, a pesar de que se mantenga un tratamiento farmacológico óptimo. Generalmente, el perfil clínico de los pacientes con trastornos del humor que son derivados a tratamiento con TEC se caracteriza por la refractariedad o mala tolerancia al tratamiento farmacológico y tendencia a la croni…
High Frequency Data Acquisition System for Modelling the Impact of Visitors on the Thermo-Hygrometric Conditions of Archaeological Sites: A Casa di D…
2018
[EN] The characterization of the microclimatic conditions is fundamental for the preventive conservation of archaeological sites. In this context, the identification of the factors that influence the thermo-hygrometric equilibrium is key to determine the causes of cultural heritage deterioration. In this work, a characterization of the thermo-hygrometric conditions of Casa di Diana (Ostia Antica, Italy) is carried out analyzing the data of temperature and relative humidity recorded by a system of sensors with high monitoring frequency. Sensors are installed in parallel, calibrated and synchronized with a microcontroller. A data set of 793,620 data, arranged in a matrix with 66,135 rows and …
Buenas prácticas en la continuidad TIC de las organizaciones
2022
Los Sistemas de Gestión de la Continuidad del Negocio (SGCN) se han convertido en uno de los objetivos prioritarios para las organizaciones, principalmente por la globalización y exigencia de sus clientes o usuarios. Es frecuente la aparición en los medios de comunicación algunas noticias relacionadas con el impacto que ha causado en los negocios la interrupción de su actividad, originado a partir de incidentes de seguridad en sus sistemas de información. Se han visto afectadas en sus operaciones organizaciones tanto de índole pública como privada. Las empresas deben de disponer de un SGCN diseñado e implantado correctamente que garantice que en un tiempo estimado puedan reanudar sus operac…
Improving Estimates Accuracy of Voter Transitions. Two New Algorithms for Ecological Inference Based on Linear Programming
2022
The estimation of RxC ecological inference contingency tables from aggregate data is one of the most salient and challenging problems in the field of quantitative social sciences, with major solutions proposed from both the ecological regression and the mathematical programming frameworks. In recent decades, there has been a drive to find solutions stemming from the former, with the latter being less active. From the mathematical programming framework, this paper suggests a new direction for tackling this problem. For the first time in the literature, a procedure based on linear programming is proposed to attain estimates of local contingency tables. Based on this and the homogeneity hypot…
