Statistical Thermodynamics of Polymer Quantum Systems
2011
Polymer quantum systems are mechanical models quantized similarly as loop quantum gravity. It is actually in quantizing gravity that the polymer term holds proper as the quantum geometry excitations yield a reminiscent of a polymer material. In such an approach both non-singular cosmological models and a microscopic basis for the entropy of some black holes have arisen. Also important physical questions for these systems involve thermodynamics. With this motivation, in this work, we study the statistical thermody- namics of two one dimensional polymer quantum systems: an ensemble of oscillators that describe a solid and a bunch of non-interacting particles in a box, which thus form an ideal…
Palinsesti del moderno. Canoni, generi, forme nella postmodernità letteraria
2005
Il riciclaggio dei materiali e delle forme della modernità letteraria, la loro ‘degradazione’ a repertorio al quale attingono le scritture di secondo grado sono alcune delle prerogative della letteratura postmoderna. In questo saggio si indaga qualcuno di questi nessi tra moderno e postmoderno nonché alcune questioni teoriche relative alla trasmissione della tradizione e alla sua ricodificazione dopo la modernità. Alle trattazioni prevalentemente teoriche dei primi due capitoli, dedicati al dibattito degli ultimi quindici anni sul canone letterario e alla trasformazione dei generi nella postmodernità, si collega specularmente la seconda parte del lavoro: l’interpretazione del Pinocchio para…
Nasal chemosensory tests: biomarker between dementia with Lewy bodies and Parkinson disease dementia.
2020
BACKGROUND: Dementia with Lewy bodies (DLB) and Parkinson disease dementia (PDD) are progressive and disabling neurodegenerative disorders, which are often misdiagnosed due to theirs overlapping clinical and paraclinical features. Nevertheless, their adequate management requires an accurate differential diagnosis. The main aim of this study was to investigate the usefulness of olfactory and trigeminal nasal testing for the differential diagnosis between DLB and PDD. METHODS: Odor thresholds to three odorants differentially activating the olfactory and trigeminal systems were assessed in patients with DLB, PDD and healthy controls (n = 20 per group). RESULTS: Odor thresholds were significant…
Spatio-Chromatic Adaptation via Higher-Order Canonical Correlation Analysis of Natural Images
2014
Independent component and canonical correlation analysis are two general-purpose statistical methods with wide applicability. In neuroscience, independent component analysis of chromatic natural images explains the spatio-chromatic structure of primary cortical receptive fields in terms of properties of the visual environment. Canonical correlation analysis explains similarly chromatic adaptation to different illuminations. But, as we show in this paper, neither of the two methods generalizes well to explain both spatio-chromatic processing and adaptation at the same time. We propose a statistical method which combines the desirable properties of independent component and canonical correlat…
Performability of Actions
2021
AbstractAction theory may be regarded as a theoretical foundation of AI, because it provides in a logically coherent way the principles of performing actions by agents. But, more importantly, action theory offers a formal ontology mainly based on set-theoretic constructs. This ontology isolates various types of actions as structured entities: atomic, sequential, compound, ordered, situational actions etc., and it is a solid and non-removable foundation of any rational activity. The paper is mainly concerned with a bunch of issues centered around the notion of performability of actions. It seems that the problem of performability of actions, though of basic importance for purely practical ap…
The Hermeneutics of Texts
2002
The second canon is the canon of the whole and the parts and implies the hermeneutical circle between the whole and the parts: understanding the whole presupposes understanding the parts and vice versa. The task of this essay is not to solve the methodological difficulties of the practical application of the canon to texts and their contexts. Such a solution would require a complicated and lengthy investigation of the different aspects of the application of the canon to the methodology of philological text interpretation and historical research concerning the original contexts of texts. A brief sketch of one simple aspect of the application of the second canon will be given in the last sect…
La controversa questione dell'aggiornamento (e dell'aumento) del canone di locazione
2018
La sentenza della Cassazione civile, Sez. III, 22 giugno 2017, n. 15348 ripropone l’annosa questione dell’aumento e dell’aggiornamento del canone di un contratto di locazione ad uso non abitativo. Dopo averla analizzata alla luce del contesto giurisprudenziale sul tema, se ne mettono in luce lacune e contraddizioni. Infine, una breve riflessione e` dedicata al tema della equiparazione della cessione di quote societarie alla cessione di azienda.
Statistical Modeling of Huffman Tables Coding
2005
An innovative algorithm for automatic generation of Huffman coding tables for semantic classes of digital images is presented. Collecting statistics over a large dataset of corresponding images, we generated Huffman tables for three images classes: landscape, portrait and document. Comparisons between the new tables and the JPEG standard coding tables, using also different quality settings, have shown the effectiveness of the proposed strategy in terms of final bit size (e.g. compression ratio).
A new brachycladiid species (Digenea) from Gervais’ beaked whale Mesoplodon europaeus in north-western Atlantic waters
2014
AbstractA new species of the digenean family Brachycladiidae Odhner, 1905 is described from the bile ducts of a Gervais’ beaked whale Mesoplodon europaeus Gervais (Ziphiidae) stranded on the North Atlantic coast of Florida. These parasites were assigned to Brachycladium Looss, 1899 and differed from other species of the genus in the relative size of the oral and ventral suckers, the form and size of the eggs and their extremely small body size. A canonical discriminant analysis was used to examine differences between these specimens and the smallest available individuals of B. atlanticum (Abril, Balbuena and Raga, 1991) Gibson, 2005, considered the morphologically closest species. The overa…
Life Satisfaction and Self-rated Health in Adolescents: The Relationships between them and the Role of Gender and Age
2020
Abstract The purpose of this study was to analyze the relationships between self-reported life satisfaction, self-rated health, gender, and age in adolescents. 1,141 secondary school students aged between 12 and 17 participated in our study. The data were analyzed using bivariate and nonlinear canonical correlation analyses. The results of the bivariate correlation analysis support the results of previous studies. Life satisfaction was positively correlated with same-day perceived health (r = .37; p < .01) and negatively correlated with anxiety/depression (r = –.37; p < .01). Same-day perceived health was positively correlated with health in the past 12 months (r = .38; p < .01) an…
