Glass transition of hard spheres in high dimensions
2009
We have investigated analytically and numerically the liquid-glass transition of hard spheres for dimensions $d\to \infty $ in the framework of mode-coupling theory. The numerical results for the critical collective and self nonergodicity parameters $f_{c}(k;d) $ and $f_{c}^{(s)}(k;d) $ exhibit non-Gaussian $k$ -dependence even up to $d=800$. $f_{c}^{(s)}(k;d) $ and $f_{c}(k;d) $ differ for $k\sim d^{1/2}$, but become identical on a scale $k\sim d$, which is proven analytically. The critical packing fraction $\phi_{c}(d) \sim d^{2}2^{-d}$ is above the corresponding Kauzmann packing fraction $\phi_{K}(d)$ derived by a small cage expansion. Its quadratic pre-exponential factor is different fr…
Dell’ostinazione e perfidia de’ Greci. Le carte della Congregazione dei Greci della prima età moderna
2021
Il contributo propone una descrizione analitica del manoscritto Miscellanea di riti greci (Branc. I.B.6) conservato presso la Biblioteca Nazionale di Napoli. Il codice raccoglie le attività di consultazione della Congregazione dei Greci (1573-1600 ca.), presieduta dal Cardinale Giulio Antonio Santorio, che hanno portato alla estensione della Perbrevis Instructio da parte di Clemente VIII, il primo corpus organico di norme riguardanti il rito greco nella Chiesa cattolica. The contribution proposes an analytical description of the Miscellaneous manuscript of Greek rites (Branc. I.B.6) preserved at the National Library of Naples. The code collects the consultation activities of the Congregatio…
Two-view “cylindrical decomposition” of binary images
2001
This paper describes the discrete cylindrical algebraic decomposition (DCAD) construction along two orthogonal views of binary images. The combination of two information is used to avoid ambiguities for image recognition purposes. This algorithm associates an object connectivity graph to each connected component, allowing a complete description of the structuring information. Moreover, an easy and compact representation of the scene is achieved by using strings in a five letter alphabet. Examples on complex digital images are also provided. © 2001 Elsevier Science Inc.
Representing 2D Digital Objects
2000
The paper describes the combination a multi-views approach to represent connected components of 2D binary images. The approach is based on the Object Connectivity Graph (OCG), which is a sub-graph of the connectivity graph generated by the Discrete Cylindrical Algebraic Decomposition(DCAD) performed in the 2D discrete space. This construction allows us to find the number of connected components, to determine their connectivity degree, and to solve visibility problem. We show that the CAD construction, when performed on two orthogonal views, supply information to avoid ambiguities in the interpretation of each image component. The implementation of the algorithm is outlined and the computati…
Qualitative analysis by experts of the essential elements of the nursing practice environments proposed by the TOP10 questionnaire of assessment of e…
2020
Background: A short TOP10 scale based on the Practice Environment Scale-Nursing Work Index questionnaire measures the characteristics of nursing work environments. Positive environments result in better quality care and health outcomes. Objective: To identify a small number of core elements that would facilitate more effective interventions by nurse managers, and compare them with the essential elements proposed by the TOP10. Method: Qualitative research by a nominal group of eight experts. The content analysis was combined with descriptive data. Results: Ten most important items were selected and analyzed by the expert group. A high level of consensus in four items (2, 15, 20, 31) and an a…
Large time behavior for a porous medium equation in a nonhomogeneous medium with critical density
2014
Abstract We study the large time behavior of solutions to the Cauchy problem for the porous medium equation in nonhomogeneous media with critical singular density | x | − 2 ∂ t u = Δ u m , in R N × ( 0 , ∞ ) , where m > 1 and N ≥ 3 , with nonnegative initial condition u ( x , 0 ) = u 0 ( x ) ≥ 0 . The asymptotic behavior proves to have some interesting and striking properties. We show that there are different asymptotic profiles for the solutions, depending on whether the continuous initial data u 0 vanishes at x = 0 or not. Moreover, when u 0 ( 0 ) = 0 , we show the convergence towards a peak-type profile presenting a jump discontinuity, coming from an interesting asymptotic simplification…
Aryl hydrocarbon receptor activation by cAMP vs. dioxin: divergent signaling pathways.
2005
Even before the first vertebrates appeared on our planet, the aryl hydrocarbon receptor ( AHR ) gene was present to carry out one or more critical life functions. The vertebrate AHR then evolved to take on functions of detecting and responding to certain classes of environmental toxicants. These environmental pollutants include polycyclic aromatic hydrocarbons (e.g., benzo[ a ]pyrene), polyhalogenated hydrocarbons, dibenzofurans, and the most potent small-molecular-weight toxicant known, 2,3,7,8-tetrachlorodibenzo- p -dioxin (TCDD or dioxin). After binding of these ligands, the activated AHR translocates rapidly from the cytosol to the nucleus, where it forms a heterodimer with aryl hydroc…
Standard of living, consumption norms, and perceived necessities
2014
Purpose– The purpose of this paper is to focus on the material conditions of peoples’ daily lives by investigating changes in the self-perceived necessities of ten technology- and leisure-related consumer goods and services between 1999 and 2009. The authors also look at the socio-demographic predictors of the perceptions and the development of the ownership of the goods under investigation.Design/methodology/approach– The data are derived from surveys “Finland – Consumption and way of life” 1999 (N=2,417), 2004 (N=3,574), and 2009 (N=1,202). The statistical analysis methods include ANOVA and descriptive statistics. Also official statistics are used.Findings– Many technological goods, in pa…
Estudio descriptivo del consumo de alcohol en los adolescentes de Gandia
2014
Resumen Introducción: La morbimortalidad en los países desarrollados se relaciona con hábitos adquiridos en la adolescencia. El alcohol es la droga más consumida por los adolescentes españoles, planteando su uso abusivo un problema preocupante para la salud pública. Objetivo: Valorar el patrón de consumo de bebidas alcohólicas de los jóvenes estudiantes de 4º de ESO de la ciudad de Gandía y las características que definen a esta población y al entorno en el que se realiza. Metodología: Se trata de un estudio descriptivo transversal del consumo de alcohol en los adolescentes de entre 15 y 18 años de Gandía, que se lleva a cabo mediante una encuesta con diferentes cuestiones relacionadas con l…
Variabilidad en la utilización de antihipertensivos entre las zonas básicas de salud de la Comunidad Valenciana
2010
ResumenObjetivosEstimar el consumo de cinco subgrupos terapéuticos empleados en el tratamiento de la hipertensión arterial en las zonas básicas de salud (ZBS) de la Comunidad Valenciana, y analizar sus variaciones.MétodosEstudio ecológico, descriptivo, del consumo de antihipertensivos en las ZBS de la Comunidad Valenciana en el año 2005, seguido de análisis de la variabilidad observada. Se estudiaron las 239 ZBS existentes mediante un análisis descriptivo de consumo (dosis diarias definidas [DDD] por 1.000 habitantes y día en pensionistas [DDD/1.000p/día] o activos [DDD/1.000a/día]) y razones estandarizadas de utilización. Para el análisis de la variabilidad se utilizaron los estadísticos d…
