Liquid markets and market liquids: collective and single-asset dynamics in financial markets

We characterize the collective phenomena of a liquid market. By interpreting the behavior of a no-arbitrage N asset market in terms of a particle system scenario, (thermo)dynamical-like properties can be extracted from the asset kinetics. In this scheme the mechanisms of the particle interaction can be widely investigated. We test the verisimilitude of our construction on two-decade stock market daily data (DAX30) and show the result obtained for the interaction potential among asset pairs.Comment: 4 pages, svjour.cls, 3 figures, to appear in The European Physical Journal

Spaceship Earth. Space-driven technologies and systems for sustainability on ground

As awareness towards the problem is growing, eco-friendliness is today a paramount requirement for all space activities and in particular for the ground segment, fully comparable to other industrial sectors. The present work focuses on the assessment and the sustainable development enhancement of a ground-based space facility, the European Astronaut Centre (EAC), located in Germany. The project is framed within the European Space Agency development of an environmental outlook, which aims not only at the full compliance with the legislation and at assessing the impact of its activities, but also at laying the foundation for future evolution through innovation. Indeed, ESA promotes the sustainable use of space as a necessity and duty for Europe. As history teaches us, technical knowledge emerged within the space sector serves as innovation driver in other industrial branches: the goal of the project is to transform the EAC building into a spaceship integrated with the territory through the conscious management of this spontaneous process, fostering the combination between the space sector and the architecture and civil engineering fields. The work explores the potential of space technologies, processes and systems applied on ground and presents a range of space-driven innovative concepts which may improve the sustainability of the EAC building, focusing on different aspects of its resource demand – energy, water and waste management – and defining the integration with the pre-existing compound, the limitation of the impact on the surrounding landscape and the participation of the local community as additional fundamental requirements. Indeed, the project embraces the full concept of sustainability, which considers not only eco-friendliness but also its balance with economic and social aspects. Two factors – a certain urgency for action, which leaves little space for research and experimentation, and a call for ground-breaking solutions – guided the design activity: taking advantage of these conflicting requirements, a comparison between standard technologies and innovative space-related concepts was performed. When dealing with complex and uncertain scenarios, decision among the possible solutions is not straightforward and needs to be supported by appropriate methodologies: a multi-criteria and quantitative decision-making tool, able to concentrate on the main goal while considering all other relevant aspects – environmental, economic, social sustainability – was therefore developed. Furthermore, the project promotes local community participation in the decisional process, as a way to enhance knowledge, generate understanding and promote towards the EAC redesign, space activities and their potential innovative impact on sustainability

Proceso de definición de prioridades institucionales de investigación en el Seguro Social de Salud del Perú, 2020-2022

Introduction: Health research priorities definition address research efforts to the promotion of health science, technology, and innovation. Material and Methods: Health research priorities in the Peruvian Social Security for the period 2020-2022 was carried out in four stages using a systematic, structured, participatory and sequential process. Results: First, the progress of the research in the priorities of the period 2017-2019 was evaluated. In the second stage, various sources were consulted to identify disease-oriented research needs and the framework for priorities oriented to health systems and health interventions. The third stage consisted of an expanded consultation to select priority disease-oriented topics. Finally, a participatory and multidisciplinary workshop was developed to select themes, subtopics, and priority areas for research. Conclusion: The final product was the definition of 11 priority themes, seven for diseases and four for health systems and health interventions.Introducción: La definición de prioridades de investigación en salud dirige los esfuerzos de investigación para promover ciencia, tecnología e innovación en salud.

Narrativas del donante de plasma convaleciente en EsSalud: motivaciones, miedos, expectativas y experiencias

Objectives: To know and explore from convalescent plasma donators' voices the experience in the blood donation process at a social security hospital. Material and Methods: Qualitative study with a phenomenological design. The investigation was carried out in 01 hospitals of the social security of Peru. Semi-structured interviews were carried out. Results: Eleven donors of convalescent plasma were interviewed. The main motivations for donating were being able to contribute to national research and supporting patients affected by COVID-19. Fears focus on the possible risk of contagion within the hospital. Donors emphasised the attention and support of health personnel alongside the donation procedure. The main expectations and suggestions point towards greater dissemination of donation campaigns with special emphasis on safety. Likewise, an improvement in the time of the donation procedure (from enrolment to the extraction of convalescent plasma), and the implementation of friendly spaces to encourage future blood donation campaigns were highlighted. Conclusions: The experience of the convalescent plasma donors was positive. However, improvements must be made in terms of processes and infrastructure to ensure future successful blood donation campaigns.Objetivos: Explorar, desde las narrativas de la población de donantes de plasma convaleciente en un ensayo clínico, las experiencias en el proceso de donación de sangre. Material y Métodos: Se realizó un estudio cualitativo con diseño fenomenológico. La investigación se llevó a cabo en un hospital de la seguridad social del Perú aplicándose entrevistas semiestructuradas a profundidad. Resultados: Se entrevistó a once donantes de plasma convaleciente. Se identificó que las principales motivaciones de los donantes fueron tanto el poder contribuir a la investigación nacional como, apoyar a pacientes afectados por la COVID-19. Los principales miedos se centran en el posible riesgo de contagio dentro del hospital. Por otro lado, los donantes resaltaron la atención y acompañamiento del personal de salud en el proceso. Las principales expectativas y sugerencias apuntan hacia una mayor difusión de las campañas de donación de sangre en general, con especial énfasis en el tema de seguridad, la mejora en el tiempo del procedimiento de donación (en el caso de la donación de plasma convaleciente, desde el enrolamiento hasta la extracción de plasma convaleciente) y, la implementación de espacios amigables para incentivar las futuras campañas de donación de sangre en  general. Conclusiones: Las experiencias de los donantes de plasma convaleciente fueron positivas. Sin embargo, aún hay mejoras que realizar a nivel de procesos e infraestructuras para asegurar campañas exitosas de donación de sangre futuras

On the rigid body behavior of foreign exchange markets

We propose a method to characterize the behavior of a foreign exchange market, introducing a mapping from the N assets to a liquid of N particles, which is studied by means of its empirical kinetic properties. We present the resulting rigid body behavior investigating daily foreign exchange market data for USD, DEM and YEN in the period of time from 9 April 1973 to 15 November 1997.

Noise reduction for vocal pathologies

A noise reduction scheme, particularly suited for the correction of vocal pathologies. is proposed. The filter makes use of concepts originated within the theory of dynamical systems and deterministic chaos. In particular. the idea of embedding scalar data in order to reconstruct a phase space is of fundamental importance here. Furthermore, the concept of an attractor as a result of dynamical constraints is exploited. In order to perform noise reduction one needs redundancy and the human voice provides it even within a phoneme, namely the smallest structural unit of speech. Due to several repetitions of a pattern called pitch inside a phoneme, separation between the pure voice signal and the noise is possible, provided the latter is uncorrelated with the former. With a proper parameter tuning, different kinds of noise can be removed, We describe the idea behind the noise reduction algorithm and present applications to vocal pathologies. (C) 2002 IPEM.
