Impact of early post-stress 99mTc sestamibi ECG-gated SPECT myocardial perfusion imaging on the detection of ischemic LV dyssynchrony: an early step in the stunning cascade
No full textTransient alterations in ventricular conduction and synchronized cardiac performance have been reported in experimental models of myocardial ischemia. In post-stress 99mTc-sestamibi-gated-SPECT myocardial perfusion imaging (MPI), the time elapsed between tracer injection and image acquisition could influence the detection of ischemic left ventricular mechanical dyssynchrony (LVMD). We aimed at evaluating whether early vs. delayed post-stress MPI improve ischemic LVMD detection using the phase analysis parameters standard deviation (SD) and histogram bandwidth (HB) and to assess the correlation between stress-induced changes in SD and HB and other functional parameters. We prospectively studied 32 control subjects (Group-1) and 60 ischemic patients (Group-2). Stress-induced changes were calculated as stress minus rest (Δ). LVMD was defined as post-stress increases of either SD or HB. Group-2 showed higher ΔSD and ΔHB in early than in delayed images: early ΔSD: 1.63 (− 0.37 to 4.83) vs. delayed ΔSD: − 0.39 (− 3.82 to 1.74); early ΔHB: 2.50 (− 4 to 12) vs. ΔHB delayed: − 4 (− 15.75 to 4), all p < 0.01. ΔSD and ΔHB correlated linearly with ΔLV-ejection-fraction (EF) and ΔLV-end systolic-volume (ESV) in early images, all p < 0.01. Early images detected LVMD in more patients than delayed scans (78% vs. 38%; p < 0.01) All patients with LVEF drop in early post-stress evaluation had LVMD. Early post-stress images improve ischemic LVMD detection. Ischemic LVEF and LVESV changes correlate with ΔSD and ΔHB.Fil: Cortés, Claudia Mariana. Fundación Favaloro; ArgentinaFil: Aramayo G, E.

In particular, since 2003, the Chapter has analyzed the main changes in Italian Copyright Law, both from European sources - the Italian implementation of Directive 2001/29/EC on the harmonisation of certain aspects of copyright and related rights in the information society (legislative decree N° 68/2003); of Directive 2001/84/EC on the resale right for the benefit of the author of an original work of art (Legislative Decree N° 118/2006); of Directive 2011/77/EU on the term of protection of copyright and certain related rights (Legislative Decree N° 22/2014); of Directive 2012/28/EU on certain permitted uses of orphan works (Legislative Decree N° 163/2014) - and from only national provisions (e.g. Articles 15, sec. 3, and 15-bis of the Italian Copyright Act on public performances of protected works in libraries, museums or cultural clubs.; the link with the Regulation of the Italian Authority on Communication about copyright protection on the net, pursuant to Article 32-bis of Legislative Decree N° 177/2005, and to Legislative Decree n° 9/2008 on audiovisual rights on sport events, etc.). These positive sources are always accompanied - also with criticism - by a wide description of case law and scholars' constructions of law and pratice of copyright and related rights in text and footnotes
Electronic Dictionaries for Information Retrieval, Automatic Textual Analysis and Semantic-Based Data Mining Software
No full textToday Lexicon-Grammar (LG) remains one of the most consistent
Natural Language Processing (NLP) approaches, especially for
Semantic-Based Data Mining (SBDM) and Semantic Web. Its main goal
is to describe all mechanisms of word combinations closely related to the
concrete use of lexical units and to sentence creation. Also, it gives an
exhaustive description of lexical and syntactic structures of several
languages. LG was set up by the French linguist Maurice Gross during
the ‘60s, and subsequently developed for and applied to Italian by
Annibale Elia, Emilio D’Agostino and Maurizio Martinelli. Its
theoretical approach is prevalently based on Zelig Sabbettai Harris’
Operator-Argument Grammar, which assumes that each human language
is a self-organizing system, and that the syntactic and semantic properties
of a given word may be calculated on the basis of the relationships this
word has with all other co-occurring words inside given sentence
contexts. Simple sentences2 are the minimal linguistic meaning structures
upon which LG founds its studies on natural language syntactic features.
In the last twenty years, LG has also reached important results in the
domain of automatic textual analysis and parsing with NLP-oriented
software such as INTEX3, UNITEX4, and more recently NOOJ5.

2 In LG, a simple sentence is formed by a unique predicative element (a verb, but
also a name or an adjective) plus all the necessary arguments it selects to achieve
acceptability and grammaticality. The study of simple sentences is completed analyzing
the rules of co-occurrence and selection restriction, which are distributional and
transformational rules based on predicate syntactic-semantic properties.

Logica dei condizionali e logica della probabilità
No full textThis paper aims at addressing some problems involving the nature of conditional sentences. The general outlines of a new theory (whose formalism has been spelled out by the author elsewhere in a pretty technical manner) are discussed here and exposed from a philosophical point of view, trying to avoid as far as possible all technicalities. In this paper it is argued that the logic of conditionals is throughout epistemic, so that it is relative to a deductively closed stock K of bivalent sentences whose truth is taken for granted. Originally, the new formalism was meant to deal only with indicative conditionals. In the present paper, thanks to the epistemic characterization of conditionals, a further generalization is introduced: it allows a unified treatment of both indicative and counterfactuals conditionals in a single framework, without any limitation in compositionality. It is argued that counterfactual conditionals are relative to a counterfactual stock K ́, obtained by contracting K in such a way that, ceteris paribus, the antecedent is dropped. It is stressed that the new theory (a) is able to satisfy, in a general way and without contradicting the so-called Lewis’s Triviality Results, the equation by which the probability of a conditional of the form «if A then C» is equal to the probability of C given A, (b) allows the definition of a new semantic (i.e. based on truth-conditions) notion of logical consequence. This new notion generalizes the classical relation of logical consequence and encompasses as well as extends the so-called Adams’s p-entailment to compounds of conditionals. These results challenge the popular view according to which conditionals intrinsically lack truth conditions, and their probability is nothing more than a «degree of assertability». Another remarkable tenet of this article is that counterfactuals that are not epistemically necessary, are contingent, meaning that they are true at certain worlds and false at other worlds, while they are neither true nor false at the actual world. In spite of this, they may be probabilistically relevant for the actual world, in the sense that analogical or inductive probabilistic inferences about the actual world may be reasonably drawn on the basis of the high probability of contingent counterfactuals

Deductive Probability, Physical Probability and Partial Entailment
No full textA new kind of logical probability is introduced, based on the relationships between logical dependence and probabilistic dependence rather than on the principle of indiffer-ence or axioms of invariance. Given its deductive nature, this kind of probability is called deductive probability. To define it, an extensive investigation is carried out into the idea of logical independence. This investigation leads to the conclusion that only the notion of logical separability, introduced by the author in a previous paper (1990), is suitable to properly characterise deductive probability.
If the definition of deductive probability is so modified that reference to logical independence is replaced with reference to physical independence, a new notion of physical probability is obtained. Since the idea of logical independence can be characterised as a degenerate case of physical independence (just as a logical truth is a degenerate case of factual proposition), deductive probability can be viewed as a degenerate case of physical probability.
The importance of deductive and physical probability (as here characterised) rely on a theorem by which both deductive and physical probability definitions uniquely determine a single probability function: the function that distributes probability uniformly among the logically possible or, respectively, physically possible elementary cases. So the present account allows for a new justification of the uniform distribution across elementary cases and therefore a new way to interpret the formulas of statistical mechanics. More precisely, the uniform distribution is neither reached via epistemic principles nor it is considered as a physical probabilistic hypothesis about frequencies, propensities or chances. It is rather considered as the only probability function preserving, by means of the probabilistic dependencies that it induces, the physical dependencies that derive from the assumed nonprobabilistic laws.
By the notion of deductive probability, a new account of partial entailment is developed. Two meanings of the term ‘partial entailment’ are distinguished. They generalise two distinct aspects of deductive total entailment. It is argued that epistemic inductive probability is adequate as an explicatum of partial entailment with respect to the first meaning while it is at odds with the second one

Chapter 3 Polychronic Narration, Trauma, Disenfranchised Grief, and Mario Alberto Zambrano’s Lotería
No full textEthnic American Literatures and Critical Race Narratology explores the relationship between narra¬tive, race, and ethnicity in the United States. Situated at the intersection of narrative theory and context-oriented approaches in race, ethnic, and cultural studies, it interrogates the complex and varied ways in which ethnic American authors use narrative form to engage readers in issues related to race and ethnicity. The book’s international group of contributors covers a wide range of primary texts that belong to the literary traditions of Latinx, African American, Native American, Asian American, Jewish American, and Arab American communities. They demonstrate that paying attention to the formal features of these texts changes our under¬standing of narrative theory and that narrative theories can help us to think about their representations of time and space, the narration of trauma and other emotional memories, and the importance of literary (meta)paratexts, genre structures, and author functions
