A risk assessment proposal for underground cavities in Hard Soils-Soft Rocks
2018
Abstract Underground calcarenite quarries in Marsala (Sicily) have been involved in a number of collapses that have, seriously damaged numerous buildings. The stability conditions were therefore examined in order to assess risk conditions within the historical centre of the town and the surrounding areas, which are subject to urban expansion. Starting with an extensive collection of historical information, the research was carried out through surveys of the cavities, systematic sampling of material, petrographic analysis and geotechnical testing. The results of laboratory tests and in situ investigations provided a geotechnical characterization of both the intact material and the rock mass.…
On the continuous and discontinuous maximal operators
2018
Abstract In the first part of this paper we study the regularity properties of a wide class of maximal operators. These results are used to show that the spherical maximal operator is continuous W 1 , p ( R n ) ↦ W 1 , p ( R n ) , when p > n n − 1 . Other given applications include fractional maximal operators and maximal singular integrals. On the other hand, we show that the restricted Hardy–Littlewood maximal operator M λ , where the supremum is taken over the cubes with radii greater than λ > 0 , is bounded from L p ( R n ) to W 1 , p ( R n ) but discontinuous.
Searching events in AFM force-extension curves: A wavelet approach
2016
An algorithm, based on the wavelet scalogram energy, for automatically detecting events in force-extension AFM force spectroscopy experiments is introduced. The events to be detected are characterized by a discontinuity in the signal. It is shown how the wavelet scalogram energy has different decay rates at different points depending on the degree of regularity of the signal, showing faster decay rates at regular points and slower rates at singular points (jumps). It is shown that these differences produce peaks in the scalogram energy plot at the event points. Finally, the algorithm is illustrated in a tether analysis experiment by using it for the detection of events in the AFM force-exte…
A heuristic, iterative algorithm for change-point detection in abrupt change models
2017
Change-point detection in abrupt change models is a very challenging research topic in many fields of both methodological and applied Statistics. Due to strong irregularities, discontinuity and non-smootheness, likelihood based procedures are awkward; for instance, usual optimization methods do not work, and grid search algorithms represent the most used approach for estimation. In this paper a heuristic, iterative algorithm for approximate maximum likelihood estimation is introduced for change-point detection in piecewise constant regression models. The algorithm is based on iterative fitting of simple linear models, and appears to extend easily to more general frameworks, such as models i…
[Management of patients with lymphatic diseases and lipoedema during the COVID-19 pandemic. Recommendations of the Spanish Group of Lymphology].
2020
Resumen La pandemia de COVID-19 es un desafío para el manejo de las patologías no COVID como la enfermedad linfática y el lipedema. La Telemedicina puede evitar la propagación del coronavirus. Se necesita un sistema que nos ayude a determinar la prioridad clínica y la selección de la asistencia presencial o telemática para cada paciente y la forma de realizarlas durante la pandemia. El Grupo Español de Linfología (GEL) ha realizado un documento de consenso con recomendaciones basadas en la bibliografía y experiencia clínica, como guía de práctica clínica en el manejo de anomalías linfáticas y lipedema durante la pandemia de COVID-19. Estas recomendaciones deben adaptarse a las característic…
Continuous and discontinuous nominal expressions in flexible (or “free”) word order languages: Patterns and correlates
2020
AbstractThis study explores continuous and discontinuous word order patterns of multi-word nominal expressions in flexible word order languages (traditionally referred to as “free word order” or “non-configurational” languages). Besides describing syntagmatic patterns, this paper seeks to identify any functional or other correlates that can be associated with different word orders. The languages under investigation are a number of Australian languages as well as Vedic Sanskrit, all of which have long been known for their syntagmatic flexibility. With respect to continuous order, evidence from several of these languages suggests that default ordering is primarily governed by functional templ…
In nomine patris: Discursive strategies and ideology in the Cosa Nostra family discourse
2017
Abstract The article investigates how Cosa Nostra family discourse is characterized by a series of discursive strategies that give shape to specific ideological structures. By analysing a TV interview to the son of Bernardo Provenzano, boss of Cosa Nostra, it is possible to understand how the criminal values and practices are maintained and reproduced within the father–son relationship. Specifically, we show how the son justifies, legitimises or denies the criminal actions of his father. The ideology of Cosa Nostra seems to be based on the inter-generational cultural continuity of its members, on the family as main locus of adherence, reductionism of its mediatic image, amoralism as father–…
“Sealfie”, “Phoque you” and “Animism”: The Canadian Inuit Answer to the United-States Anti-sealing Activism
2018
A corpus made by online Canadian newspaper articles, coming from the archives of CBC News, Vice Canada and Huffington Post Canada, and related multimedia contents such us audio interviews, videos and especially links to images and comments shared on Twitter, allows us to reconstruct the debate on the seal hunt that involved Canadian media in 2014. In specific, we propose an interpretation of the pro-sealing discourse by Canadian Inuit and Newfoundlanders as an ironic and incisive answer to the serious United States animal rights activists discourse, explaining how these two different points of view on animals come from a different experience of the environment and a different conception of …
Modeling mass transfer in fracture flows with the time domain-random walk method
2019
The time domain-random walk method was developed further for simulating mass transfer in fracture flows together with matrix diffusion in surrounding porous media. Specifically, a time domain-random walk scheme was developed for numerically approximating solutions of the advection-diffusion equation when the diffusion coefficient exhibits significant spatial variation or even discontinuities. The proposed scheme relies on second-order accurate, central-difference approximations of the advective and diffusive fluxes. The scheme was verified by comparing simulated results against analytical solutions in flow configurations involving a rectangular channel connected on one side with a porous ma…
Climatic gradients along the windward slopes of Mount Kenya and their implication for crop risks. Part 1: climate variability
2012
In tropical mountains, the way topographical gradients translate in terms of intra-seasonal and interannual climate variability (especially rainfall and evapotranspiration) is relatively unknown, yet it is an important issue for agriculture and food security. The eastern slopes of Mount Kenya, in East Africa, with their wide range of agro-ecological conditions, are appropriate for the study of these aspects. Daily (monthly) rainfall data from 11 (24) stations at different elevations and exposures are collected for the period 1961-2006. For the elevation belts suitable for farming and agro-pastoral activities, mostly below 2000 m, it is found that not all rainfall characteristics co-vary wit…
