Editorial: Psychophysiology of Stress

Stress is a multifactorial complex phenomenon where organic resources are mobilized to deal with a real or perceived threat (Cohen et al., 1983). The stress response is one of the most important phylogenetic coping mechanisms that have allowed humans to successfully adapt to highly demanding and potentially dangerous contexts (Hadany et al., 2006; Korzan and Summers, 2021). The intrinsic neurobiological mechanisms involved in the stress response have not changed much in the last stages of the evolution of the human being, prominently including the hypothalamic-pituitary-adrenocortical axis and the autonomic nervous system (Ulrich-Lai and Herman, 2009;McEwen et al., 2015; Cohen et al., 2016). In contrast, our social context has changed dramatically recently in evolutionary terms

Urban Water Pricing: The Metro Manila and Metro Cebu Cases

Water is a critical commodity for human survival and a scarce resource that must be appropriately priced to ensure that it is not wastefully and unsuitably consumed. This Notes offers an optimal pricing scheme, together with suggestions on the improvement of the overall water resource management that could provide the proper environment by which such pricing scheme can succeed.urban management, water sector, water demand

Towards a definition of quantum integrability

We briefly review the most relevant aspects of complete integrability for classical systems and identify those aspects which should be present in a definition of quantum integrability. We show that a naive extension of classical concepts to the quantum framework would not work because all infinite dimensional Hilbert spaces are unitarily isomorphic and, as a consequence, it would not be easy to define degrees of freedom. We argue that a geometrical formulation of quantum mechanics might provide a way out.Comment: 37 pages, AmsLatex, 1 figur

Uso de los probióticos desde la farmacia comunitaria

Los probióticos son microorganismos vivos que ejercen una acción beneficiosa sobre el hospedador al administrarse en las cantidades adecuadas. Además, han de cumplir los criterios de la FAO para ser considerados como tal. En este trabajo se va a realizar una revisión bibliográfica sobre los estudios encontrados del uso de probióticos en diferentes patologías, con una antigüedad máxima de diez años. Se desarrollarán más las patologías en las que hay más estudios, por ser más conocidas; así como aquellas en las que su uso es más novedoso. Se tratará el uso de probióticos en diarrea, erradicación de Helicobacter pylori, síndrome de intestino irritable, enfermedad inflamatoria intestinal, enterocolitis necrotizante, cáncer de colon, intolerancia a la lactosa, alergias - enfermedades atópicas - respuesta inmune, mastitis, enfermedades urogenitales y salud bucodental

GOOGLE EARTH ENGINE: APPLICATION OF ALGORITHMS FOR REMOTE SENSING OF CROPS IN TUSCANY (ITALY)

Abstract. Remote sensing has become an important mean to assess crop areas, specially for the identification of crop types. Google Earth Engine (GEE) is a free platform that provides a large number of satellite images from different constellations. Moreover, GEE provides pixel-based classifiers, which are used for mapping agricultural areas. The objective of this work is to evaluate the performance of different classification algorithms such as Minimum Distance (MD), Random Forest (RF), Support Vector Machine (SVM), Classification and Regression Trees (CART) and Na¨ıve Bayes (NB) on an agricultural area in Tuscany (Italy). Four different scenarios were implemented in GEE combining different information such as optical and Synthetic Aperture Radar (SAR) data, indices and time series. Among the five classifiers used the best performers were RF and SVM. Integrating Sentinel-1 (S1) and Sentinel-2 (S2) slightly improves the classification in comparison to the only S2 image classifications. The use of time series substantially improves supervised classifications. The analysis carried out so far lays the foundation for the integration of time series of SAR and optical data

Boundary conditions: The path integral approach

The path integral approach to quantum mechanics requires a substantial generalisation to describe the dynamics of systems confined to bounded domains. Non-local boundary conditions can be introduced in Feynman's approach by means of boundary amplitude distributions and complex phases to describe the quantum dynamics in terms of the classical trajectories. The different prescriptions involve only trajectories reaching the boundary and correspond to different choices of boundary conditions of selfadjoint extensions of the Hamiltonian. One dimensional particle dynamics is analysed in detail.Comment: 8 page

Complex delay dynamics on railway networks from universal laws to realistic modelling

This is the final version. Available from EDP Sciences via the DOI in this record.The datasets supporting the conclusions of this article are included within the article (and its additional files).Railways are a key infrastructure for any modern country. The reliability and resilience of this peculiar transportation system may be challenged by different shocks such as disruptions, strikes and adverse weather conditions. These events compromise the correct functioning of the system and trigger the spreading of delays into the railway network on a daily basis. Despite their importance, a general theoretical understanding of the underlying causes of these disruptions is still lacking. In this work, we analyse the Italian and German railway networks by leveraging on the train schedules and actual delay data retrieved during the year 2015. We use these data to infer simple statistical laws ruling the emergence of localized delays in different areas of the network and we model the spreading of these delays throughout the network by exploiting a framework inspired by epidemic spreading models. Our model offers a fast and easy tool for the preliminary assessment of the effectiveness of traffic handling policies, and of the railway network criticalities.John Templeton FoundationAustrian Research Promotion Agency FFGNewton International FellowshipThe Royal SocietyThe British AcademyAcademy of Medical Science
