Inferring directionality of coupled dynamical systems using Gaussian process priors: Application on neurovascular systems

2022

Dynamical system theory has recently shown promise for uncovering causality and directionality in complex systems, particularly using the method of convergent cross mapping (CCM). In spite of its success in the literature, the presence of process noise raises concern about CCM's ability to uncover coupling direction. Furthermore, CCM's capacity to detect indirect causal links may be challenged in simulated unidrectionally coupled Rossler-Lorenz systems. To overcome these limitations, we propose a method that places a Gaussian process prior on a cross mapping function (named GP-CCM) to impose constraints on local state space neighborhood comparisons. Bayesian posterior likelihood and…

Oral lichenoid disease as a premalignant condition : the controversies and the unknown

2009

We grouped as oral lichenoid disease (OLD) a series of chronic inflammatory processes with autoimmune base that affect the epithelium of the oral mucosa. This disease presents in 2% of the population with a marked predilection for the female gender, especially perimenopausal women. Clinically, it is characterized by the presence of lineal reticular papules and histologically by liquefaction degeneration of the basal layer of the epithelium associated with an inflammatory infiltrate with a "band-like" disposition on the lamina propria, composed primarily of T lymphocyte cells. Its pathogenicity is associated with deregulation of the cellular immune system, where the activated cytotoxic CD8 a…

Assessing Transfer Entropy in cardiovascular and respiratory time series: A VARFI approach

2021

In the study of complex biomedical systems represented by multivariate stochastic processes, such as the cardiovascular and respiratory systems, an issue of great relevance is the description of the system dynamics spanning multiple temporal scales. Recently, the quantification of multiscale complexity based on linear parametric models, incorporating autoregressive coefficients and fractional integration, encompassing short term dynamics and long-range correlations, was extended to multivariate time series. Within this Vector AutoRegressive Fractionally Integrated (VARFI) framework formalized for Gaussian processes, in this work we propose to estimate the Transfer Entropy, or equivalently G…

Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia

2018

The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…

tale percentuale se considerata per i comuni costieri supera il 75% del territorio urbanizzato. Nel caso dei sistemi naturali i fenomeni di pressione umana pesano su una situazione già critica data da una distribuzione puntuale delle aree protette. Il livello di frammentazione e isolamento di queste aree rischia di peggiorare. In Sicilia l'assenza di strumenti di valutazione ambientale e lo scollamento tra pianificazione urbana e regionale e pianificazione settoriale hanno determinato un inadeguato livello di controllo della pressione umana sui sistemi ambientali. Riguardo a questo quadro generale il presente documento presenta un chiarimento e una riformulazione del rapporto di reciprocità tra ambiente edificato e territorio aperto con l'obiettivo di individuare possibili strategie per gestire i fenomeni di dispersione urbana nel contesto metropolitano obiettivo principale delle politiche territoriali europee e di molte politiche nazionali degli Stati membri.Settore ICAR/20 - Tecnica E Pianificazione UrbanisticaIl consumo del suolo a causa dell'urbanizzazione è un fenomeno già da molti anni sotto osservazione ma di cui solo l'ambiente scientifico ha notato l'elevato impatto ambientale. Da un punto di vista disciplinare è possibile individuare una linea di ricerca incentrata sull'analisi e l'identificazione di nuove morfologie dell'urbanizzazione e sull'interazione tra i diversi modelli insediativi che coesistono in un contesto specifico. Questa lettura si integra con la produzione scientifica sulle forme di pressione insediativa sui sistemi ambientali producendo cambiamento e deterioramento degli ecosistemi naturali e perdita di biodiversità. Un riferimento necessario per questa linea sono gli studi sui processi di frammentazione (lineare concentrato misto) e quelli sulla segregazione degli habitat naturali e seminaturali (protetti o non protetti). Tali riferimenti si combinano con le analisi condotte sul processo di sostituzione dei sistemi naturali con l'ecomosaico artificiale. Lo stato dell'urbanizzazione in Sicilia è interessato dal fenomeno della dispersione urbana che a partire dagli anni Settanta ha contribuito fortemente a plasmare il territorio regionale sia dal punto di vista fisico che funzionale. Tale fenomeno ha interessato principalmente le aree marginali intorno alle aree metropolitane dove i terreni consumati dagli insediamenti a bassa densità abitativa rappresentano il 42% dell'intero territorio urbanizzatoSettore ICAR/21 - Urbanistica

Task-focused behaviour and mothers' causal attributions in relation to dyslexia : a follow-up from age 8 to age 20

2018

Children with dyslexia tend to find reading stressful. Coping responses, such as task-focused and avoidant behaviours, can help mitigate the stress. Task-focused behaviour is associated with reading development, with others’ at-tributions of success and failure linked to task-focused behaviour. The present study aims to examine whether differences in task-focused behaviour between those with dyslexia and those without dyslexia exist in childhood (age 8) and persist in adolescence (age 15) and early adulthood (age 20). The study also aimed to understand the relationship between mothers’ causal attributions of their 15-year-old adolescents’ school successes and fail-ures and task-focused beha…

La destrucció del patrimoni artístic i la seua reconstrucció. Un exercici de microhistòria: el cas de Llíria i la Confraria de la Sang (1936-1949)

2020

The problem of artistic destruction and its reconstruction has been little studied. Using a microhistorical analysis method, we study the town of Lliria (Valencia) and its brotherhood of ?La Sang de Jesucrist? (had a great heritage from the 16th to the 19th centuries), and we also analyze how and why this destruction and reconstruction was generated during the context of the civil war. We use and combine different sources (public of the ?Causa General? and private of the ?Minute Books?) for this research, with the intention of specifying the analysis of this complex process. We also explain social and artistic relationships of these two processes, that help us study the workshops of the mos…

Essays concerning Hume's natural philosophy

2016

The subject of this essay-based dissertation is Hume’s natural philosophy. The dissertation consists of four separate essays and an introduction. These essays do not only treat Hume’s views on the topic of natural philosophy, but his views are placed into a broader context of history of philosophy and science, physics in particular. The introductory section outlines the historical context, shows how the individual essays are connected, expounds what kind of research methodology has been used, and encapsulates the research contributions of the essays. The first essay treats Newton’s experimentalist methodology in gravity research and its relation to Hume’s causal philosophy. It is argued tha…

Il regime processuale delle eccezioni di difetto di legittimazione attiva e passiva e di difetto di titolarità del rapporto. La parola alle Sezioni U…

2015

Il contributo, muovendo dall'esame all'ordinanza di remissione alle Sezioni Unite Cass. 13 febbraio 2015 n. 2977, si propone di riesaminare la vexata quaestio della distinzione tra (difetto di) legittimazione attiva e passiva e (difetto di) titolarità delle posizioni giuridiche, attive e passive, dedotte. Si affronta, in particolare, il problema dell'identità o della diversità delle due fattispecie e, sopratutto, si analizza il loro regime processuale nel sistema delle eccezioni. In particolare si conclude che nessuna delle due potenziali difese del convenuto - difetto di legittimazione e della titolarità della posizione giuridica dedotta - costituisce un'eccezione in senso stretto, bensì: …

Developing a metatheoretical framework for second language development : a cultural-historical theory and dynamic systems theory perspective

2017

The main aim of this article-based dissertation is to construct and articulate a dialectical metatheoretical architecture for the study of second language development termed Purposive-Historical Systems Theory (PHiST) invoking, inter alia, the axiomatic imperatives of dynamic systems theory (DST), Vygotskian cultural-historical theory (CHT), and Pepperian root metaphor theory (RMT). Specifically, it primarily purports, first, to demonstrate the tenability of a dialectical synthesis of DST and CHT; second, to philosophize on the fundamental contours of PHiST; third, to apply a novel metatheoretical perspective, as a quintessential example, to reconceptualizing the seminal construct of the Zo…
