Abnormal textures identification based on digital Hilbert optics methods: fundamental transforms and models
2018
The article presents the abnormal textures identification technology based on structural and statistical models of amplitude-phase images (APIm)– multidimensional data arrays (semantic models) and statistical correlation analysis methods using the generalized discrete Hilbert transforms (DHT)– 2D Hilbert (Foucault) isotropic (HTI), anisotropic (HTA) and total transforms – AP-analysis (APA) to calculate the APIm. The identified fragments of textures are obtained as examples of experimental observation of real mammograms contains areas of pathological tissues. The DHT based information technology as conceptual chart description is discussed and illustrated with DHO domain images. As additiona…
Scritti scelti di Antonino Mineo
2011
Questo volume presenta una selezione ragionata degli scritti di Antonino Mineo (1936-2008), di cui mantiene la veste tipografica originale. La raccolta di scritti è preceduta dai lavori di Giuseppe Burgio, Marcello Chiodi e Vittorio Frosini, presentati in occasione della “Giornata in ricordo di Antonino Mineo”, tenuta il 22 maggio 2009 presso la Facoltà di Economia di Palermo ed al termine della quale è stata intitolata ad Antonino Mineo un'aula del dipartimento di Scienze Statistiche e Matematiche “Silvio Vianelli”. I lavori di Giuseppe Burgio e Vittorio Frosini sono due contributi originali presentati in quella giornata di studio, sul tema delle curve normali di ordine p, che è stato uno …
Tiempos felices: Transformaciones en las tecnologías psicológicas de gobierno de la subjetividad
2020
This paper traces some inflections in the psy disciplines? discourses and technologies for the government of subjectivity during the last decades. It is focused on exploring different mechanisms through which psychological disciplines ?their discourses, techniques and practices? penetrate social life and contribute to establishing subject models consistent with transformations in the political and economic rationalities of late capitalism. Drawing on previous research in the field of gender politics and happiness discourses in the pop psychological culture, I track a line with three moments: i) the production of psychological individuality and identity normalization; ii) the proliferation o…
Social Interactions of Dat-Het Epi-Genotypes Differing for Maternal Origins: The Development of a New Preclinical Model of Socio-Sexual Apathy
2021
Social interaction is essential for life but is impaired in many psychiatric disorders. We presently focus on rats with a truncated allele for dopamine transporter (DAT). Since heterozygous individuals possess only one non-mutant allele, epigenetic interactions may unmask latent genetic predispositions. Homogeneous “maternal” heterozygous offspring (termed MAT-HET) were born from dopamine-transporter knocked-out (DAT-KO) male rats and wild-type (WT) mothers
Extracting Conditionally Heteroskedastic Components using Independent Component Analysis
2020
In the independent component model, the multivariate data are assumed to be a mixture of mutually independent latent components. The independent component analysis (ICA) then aims at estimating these latent components. In this article, we study an ICA method which combines the use of linear and quadratic autocorrelations to enable efficient estimation of various kinds of stationary time series. Statistical properties of the estimator are studied by finding its limiting distribution under general conditions, and the asymptotic variances are derived in the case of ARMA-GARCH model. We use the asymptotic results and a finite sample simulation study to compare different choices of a weight coef…
Normal, Abby Normal, Prefix Normal
2014
A prefix normal word is a binary word with the property that no substring has more 1s than the prefix of the same length. This class of words is important in the context of binary jumbled pattern matching. In this paper we present results about the number \(\textit{pnw}(n)\) of prefix normal words of length n, showing that \(\textit{pnw}(n) =\Omega\left(2^{n - c\sqrt{n\ln n}}\right)\) for some c and \(\textit{pnw}(n) = O \left(\frac{2^n (\ln n)^2}{n}\right)\). We introduce efficient algorithms for testing the prefix normal property and a “mechanical algorithm” for computing prefix normal forms. We also include games which can be played with prefix normal words. In these games Alice wishes t…
Different trends of neighboring populations of Lesser Kestrel: Effects of climate and other environmental conditions
2019
The sensitivity of population trends to the climate and environment is generally considered a species-specific trait. However, evidence that populations may show different responses to the climate and environmental conditions is growing. Whether this differential sensitivity may arise even among neighboring populations remains elusive. We compared the trends of two neighboring populations of the Lesser Kestrel Falco naumanni, using data from a 12-year survey of 158 colonies in Sicily, Italy; the two populations inhabiting a lowland and an highland area, respectively. Population trends were modeled through the TRIM algorithms implemented in R (package rtrim). A reversed U-shaped population t…
Retrieving and broadcasting near-real-time biophysical parameters from MODIS and SEVIRI receiving stations at the global change unit of the Universit…
2015
We present here the automatic processing chains implemented at the Global Change Unit of the University of Valencia. These allow for a near-real-time retrieval of various biophysical parameters from both Sun-synchronous TERRA/AQUA Moderate Resolution Imaging Spectroradiometer MODIS and geostationary Meteosat Second Generation Spinning Enhanced Visible and Infrared Imager MSG SEVIRI sensors. Retrieved parameters, namely sea and land surface temperatures SST and LST, respectively, normalized difference vegetation index NDVI, and vegetation condition index VCI, are similar for both sensors, and specific approaches have been developed and implemented for near-real-time parameter retrievals: htt…

Normalization 2.0: A longitudinal analysis of German online campaigns in the national elections 2002–9
2011
This article examines the functional, relational and discursive dimensions of the normalization thesis in one study, for both Web 1.0 and Web 2.0 features, in a longitudinal design. It is based on a quantitative content and structural analysis of German party websites in the national elections between 2002 and 2009. The results show that the normalization thesis holds true in all its dimensions over time and in the Web 2.0 era: parties still focus on the top-down elements of information provision and delivery while interactive options are scarce. The digital divide between parliamentary and non-parliamentary parties has narrowed over time, but remains visible for all online functions in 200…
