Coherent conditional probabilities and proper scoring rules
2011
In this paper we study the relationship between the notion of coherence for conditional probability assessments on a family of conditional events and the notion of admissibility with respect to scoring rules. By extending a recent result given in literature for unconditional events, we prove, for any given strictly proper scoring rule s, the equivalence between the coherence of a conditional probability assessment and its admissibility with respect to s. In this paper we focus our analysis on the case of continuous bounded scoring rules. In this context a key role is also played by Bregman divergence and by a related theoretical aspect. Finally, we briefly illustrate a possible way of defin…

Nonlinear evolution equations for turbulent superfluids
2010
In this paper a system of evolution equations for turbulent superfluid helium is written in the nonlinear regime, choosing as fundamental fields the density, the velocity, the heat flux, the non-equilibrium temperature and the average vortex line density per unit volume. Approximate equations are written, where second order terms in the non-equilibrium quantities are retained.
The two-fluid extended model of superfluid helium
2019
In this paper we perform the first numerical comparison between the two main existing models of superfluid helium: the two-fluid model proposed by Landau and the one-fluid extended model proposed from the extended thermodynamics. The numerical experiments in this paper regard the profiles of the so-called normal and superfluid components in 2D counterflow turbulence.
Analyses of udder health in Valle del Belice dairy sheep using SCC
2005
Intramammary infections (IMI) are a complex of inflammatory diseases of the mammary gland. Mastitis is one of the most frequent IMI affecting small dairy ruminants. Direct selection against clinical mastitis is difficult because mastitis in not widely recorded; therefore, somatic cell count (SCC) is promoted as selection criterion for mastitis resistance. A dataset containing 2,457 first- lactation Valle del Belice ewes from 14 flocks recorded from 1998 to 2003 was analysed. In total 116 sires with at least four daughters with a record were included in the pedigree file. Test-day IMI events were coded as a binary trait using a SCC cut-off value of 750,000 cells/ml. Analyses of risk factors …
Rigenerazione dell’area dell’ex fabbrica tessile Gulì a Palermo
2018
L’attività industriale palermitana, pur avendo vissuto un periodo fiorente piuttosto breve, ha lasciato tracce ben riconoscibili e identificabili all’interno del tessuto urbano, con manufatti architettonici di notevole importanza per qualità di progetto e dimensioni. L’ex fabbrica tessile Gulì è un complesso interessante sia dal punto di vista architettonico sia per la sua localizzazione urbanistica, molto prossima a poli di rilevante interesse culturale. Lo studio, condotto presso il Dipartimento di Architettura dell’Ateneo di Palermo, propone un intervento di rigenerazione che coinvolge non solo i manufatti edilizi presenti ma l’intera area e la sua trasformazione in un nuovo centro di qu…
Multimetallic Oxynitrides Nanoparticles for a New Generation of Photocatalysts
2019
A versatile synthetic strategy for the preparation of multimetallic oxynitrides has been designed and here exemplarily discussed considering the preparation of nanoscaled zinc-gallium oxynitrides and zinc-gallium-indium oxynitrides, two important photocatalysts of new generation, which proved to be active in key energy related processes from pollutant decomposition to overall water splitting. The synthesis presented here allows the preparation of small nanoparticles (less than 20 nm in average diameter), well-defined in size and shape, yet highly crystalline and with the highest surface area reported so far (up to 80 m2 g-1 ). X-ray diffraction studies show that the final material is not a…
La atmósfera del punto de venta y el valor de marca. Propuesta de un modelo extendido en la gran distribución colombiana
2021
El valor de marca es reconocido en el ámbito académico y empresarial como una variable clave para la organización, desde una perspectiva del consumidor el valor de marca mejora la eficiencia de los esfuerzos de marketing y la gestión de marca aportando valor a los consumidores. Esta Tesis Doctoral tiene como objetivo identificar cómo la atmósfera del punto de venta, en tanto que elemento de la comunicación de marketing, puede impulsar el valor de marca en el entorno minorista, reconociendo en dicho valor una doble perspectiva de análisis: valor de marca de la tienda vs. valor de marca patrocinada o de la marca del distribuidor; además, identifica los efectos del valor de marca en el valor p…
CYGD: the Comprehensive Yeast Genome Database.
2005
The comprehensive resource is available under http://mips.gsf.de/genre/proj/yeast/.; International audience; The Comprehensive Yeast Genome Database (CYGD) compiles a comprehensive data resource for information on the cellular functions of the yeast Saccharomyces cerevisiae and related species, chosen as the best understood model organism for eukaryotes. The database serves as a common resource generated by a European consortium, going beyond the provision of sequence information and functional annotations on individual genes and proteins. In addition, it provides information on the physical and functional interactions among proteins as well as other genetic elements. These cellular network…
Vegetation Patterns in the Hyperbolic Klausmeier Model with Secondary Seed Dispersal
2023
This work focuses on the dynamics of vegetation stripes in sloped semi-arid environments in the presence of secondary seed dispersal and inertial effects. To this aim, a hyperbolic generalization of the Klausmeier model that encloses the advective downhill transport of plant biomass is taken into account. Analytical investigations were performed to deduce the wave and Turing instability loci at which oscillatory and stationary vegetation patterns arise, respectively. Additional information on the possibility of predicting a null-migrating behavior was extracted with suitable approximations of the dispersion relation. Numerical simulations were also carried out to corroborate theoretical pre…
