Relative risk estimation of dengue disease at small spatial scale
2017
Abstract Background Dengue is a high incidence arboviral disease in tropical countries around the world. Colombia is an endemic country due to the favourable environmental conditions for vector survival and spread. Dengue surveillance in Colombia is based in passive notification of cases, supporting monitoring, prediction, risk factor identification and intervention measures. Even though the surveillance network works adequately, disease mapping techniques currently developed and employed for many health problems are not widely applied. We select the Colombian city of Bucaramanga to apply Bayesian areal disease mapping models, testing the challenges and difficulties of the approach. Methods…
Accurate representation of the distributions of the 3D Poisson-Voronoi typical cell geometrical features
2019
Understanding the intricate and complex materials microstructure and how it is related to materials properties is an important problem in the Materials Science field. For a full comprehension of this relation, it is fundamental to be able to describe the main characteristics of the 3-dimensional microstructure. The most basic model used for approximating steel microstructure is the Poisson-Voronoi diagram. Poisson-Voronoi diagrams have interesting mathematical properties, and they are used as a good model for single-phase materials. In this paper we exploit the scaling property of the underlying Poisson process to derive the distribution of the main geometrical features of the grains for ev…
Dynamics of molybdenum nano structure formation on the TiO2(110) surface: A kinetic Monte Carlo approach
2006
Abstract The rutile TiO 2 (1 1 0) surface is a highly anisotropic surface exhibiting “channels” delimited by oxygen rows. In previous experimental and theoretical DFT works we could identify the molybdenum adsorption sites. They are located inside the channels. Moreover, experimental studies have shown that during subsequent annealing after deposition, special molybdenum nano structures can be formed, especially two monolayer high pyramidal chains of atoms. In order to better understand the dynamics of nano structure formation, we present a kinetic Monte Carlo study on diffusion and adsorption of molybdenum atoms on a TiO 2 (1 1 0) surface. A quasi one-dimensional lattice gas model has been…
Weighted-average least squares estimation of generalized linear models
2018
The weighted-average least squares (WALS) approach, introduced by Magnus et al. (2010) in the context of Gaussian linear models, has been shown to enjoy important advantages over other strictly Bayesian and strictly frequentist model averaging estimators when accounting for problems of uncertainty in the choice of the regressors. In this paper we extend the WALS approach to deal with uncertainty about the specification of the linear predictor in the wider class of generalized linear models (GLMs). We study the large-sample properties of the WALS estimator for GLMs under a local misspecification framework that allows the development of asymptotic model averaging theory. We also investigate t…
Replication of linkage of familial hypobetalipoproteinemia to chromosome 3p in six kindreds
2002
Familial hypobetalipoproteinemia (FHBL) is a genetically heterogeneous condition characterized by very low apolipoprotein B (apoB) concentrations in plasma and/or low levels of LDL-cholesterol (LDL-C) with a propensity to developing fatty liver. In a minority of cases, truncation-specifying mutations of the apoB gene (APOB) are etiologic, but the genetic basis of most cases is unknown. We previously reported linkage of FHBL to a 10 cM region on 3p21.1-22 in one kindred. The objectives of the current study were to identify other FHBL families with linkage to 3p and to narrow the FHBL susceptibility region on 3p. Six additional FHBL kindreds unlinked to the APOB region on chromosome 2 were ge…
A comparison of two indirect methods for estimating average levels of gene flow using microsatellite data.
1999
We compare the performance of Nm estimates based on FST and RST obtained from microsatellite data using simulations of the stepwise mutation model with range constraints in allele size classes. The results of the simulations suggest that the use of microsatellite loci can lead to serious overestimations of Nm, particularly when population sizes are large (N5000) and range constraints are high (K20). The simulations also indicate that, when population sizes are small (N/= 500) and migration rates are moderate (Nm approximately 2), violations to the assumption used to derive the Nm estimators lead to biased results. Under ideal conditions, i.e. large sample sizes (ns/= 50) and many loci (nl/=…
Social relations in older adults: Secular trends and longitudinal changes over a 16-year follow-up.
2010
Abstract Drawing on population studies in Finland, we investigated secular trends and longitudinal changes in social relations. The cohort comparison data comprised on 974 persons aged 65–69 years from three cohorts born between 1919 and 1939 and interviewed in 1988, 1996 and 2004. Longitudinal analyses were conducted for 635 persons aged 65–74 years over a 16-year follow-up at three measurement points. Social relations were studied on the basis of frequency seeing one's offspring, perceptions of the sufficiency of these contacts, and by asking whom the participants considered as their closest person and how often and in how many tasks they helped someone. The cohort comparisons showed that…
Libri di Architettura nelle biblioteche private del XVIII secolo
2007
Attraverso lo studio comparato dei cataloghi delle biblioteche private degli architetti Giacomo Amato, Giovanni Amico, Carlo Infantolino e del principe Ignazio Paternò Castello, il testo mostra quanto ampia e varia fosse la circolazione di libri e incisioni d’architettura in Sicilia tra Seicento e Settecento e quali fossero i testi di maggiore successo editoriale.
Giacomo Serpotta tra sacro e profano
2022
We shall be taking an innovative and original approach in our examination of the insuperable figure of Giacomo Serpotta, an outstanding Sicilian stucco sculptor of the 18th century. The complete artistic output of Giacomo Serpotta is traced, oscillating between the sacred and the profane in the sculptural adornment of many churches and oratories. Here, Giacomo Serpotta shifts from the Baroque to Rococo, originating a sculptural art that is profoundly innovative in its language and symbology. Formal reading and chromatic-spatial games are intertwined with the symbolic in the light of significant essays by Carl Gustav Jung, Martin Heidegger and Carlo Giulio Argan
Porta Nuova a Palermo (XVI secolo). La vicenda, i protagonisti , i modelli, in Entrare in città: di archi e di porte, numero monografico della rivist…
2015
La Porta Nuova a Palermo, realizzata nel corso della seconda metà del Cinquecento, costituisce un episodio singolare per le molteplici valenze funzionali, simboliche e celebrative e per il carattere eccezionale della sua figurazione legata alla retorica trionfalistica di Carlo V. I differenti cantieri che si sono susseguiti delineano una vicenda complessa e originale, strettamente connessa con quelle della via Toledo e del Palazzo Reale (al quale la porta è collegata), e ricca di personalità e apporti esterni. Il ruolo dell’ingegnere regio Antonio Salamone coinvolto in tale vicenda e le analogie con talune soluzioni adottate in altre realizzazioni del tempo possono contribuire a ridefinire …
