Una fila di piccole rane tutte diverse: il Clan Nabokov di Chiara Montini
No full textEssere il figlio di un grande scrittore è tutt’altro che semplice, in special modo se finisci per essere il traduttore in varie lingue e il curatore del paterno lascito. Ancora più difficile, se il padre in questione è Vladimir Nabokov, un autore che oppose, sino al suo respiro ultimo, una granitica resistenza – tanto solida quanto lo era il suo incomparabile narcisismo difensivo – al pensiero di Freud e all’ambivalenza che insidia (e in fondo arricchisce) ogni vero affetto.
Being the son of a great writer is far from simple, especially if you end up becoming the translator into various languages and the curator of the paternal legacy. Even more difficult, if the father in question is Vladimir Nabokov, an author who until his last breath opposed a granite resistance – as solid as his incomparable defensive narcissism – to Freudian thought and to the ambivalence that undermines (and ultimately enriches) any true affection
Combining rate-adaptive cardiac pacing algorithms via multiagent negotiation
No full textSimulating and controlling physiological phenomena are notoriously complex tasks to tackle and require accurate models of the phenomena of interest. Currently, most physiological processes are described by a set of partial models capturing specific aspects of the phenomena, and usually their composition does not produce effective comprehensive models. A current open issue is thus the development of techniques able to effectively describe a phenomenon starting from partial models. This is particularly relevant for heart rate regulation modeling where a large number of heterogeneous partial models exists. In this paper we make the original proposal of adopting a multiagent paradigm, called anthropic agency, to provide a powerful and flexible tool for combining partial models of heart rate regulation for adaptive cardiac pacing applications. The partial models are embedded in autonomous computational entities, called agents, that cooperatively negotiate in order to smooth their conflicts on the values of the variables forming the global model the multiagent system provides. We experimentally evaluate our approach and we analyze its properties
Sognare il nulla: I sogni di Nìlfilo
No full textABSTRACT IN ITALIANO
Ardua sempre la trascrizione letteraria dei sogni, o forse meglio, il tentativo di far letteratura dai folli spettacoli notturni di Òneiros. Nel caso di questi Sogni di Nìlfilo, la difficoltà è duplicata dal fatto che il suo autore, Giuseppe Finocchiaro, è un eccellente disegnatore e pittore – oltreché un coltissimo bibliografo – prima ancora di essere uno scrittore. Che sin dal titolo quest’opera rimandi alla leggendaria Hypnerotomachia Poliphili è evidente, ma di una post-novecentesca Hypnerotomachia in chiave di nulla trattasi: se infatti Poliphilo ama molte cose (il suo nome stesso lo dichiara), nonché Polia (altro nome parlante che, appunto, molte cose significa), Nìlfilo sembrerebbe amare il nulla e la sua fantasmatica, nullificante Nìlia. Raccolta onirica raffinatissima, si diceva, in forma dialogica, I sogni di Nìlfilo sono scritti con una prosa poetica ricchissima di endecasillabi dal nitore esistenzial-montaliano e illustrati con disegni a matita in bianco e nero di straordinario splendore. Freud passò di qui (magari in compagnia di Eraclito), e con lui la fiducia nell’irriducibile unicità del soggetto umano, o non piuttosto Jung che tutto, alla fine, al collettivo riconduce?
ABSTRACT IN ENGLISH
The literary transcription of dreams is always difficult, or perhaps better yet, the attempt to make literature out of Òneiros' crazy nocturnal shows. In the case of these Dreams of Nìlfilo, the difficulty is doubled by the fact that its author, Giuseppe Finocchiaro, is an excellent draftsman and painter - as well as a highly cultured bibliographer - even before being a writer. That right from the title this work refers to the legendary Hypnerotomachia Poliphili is evident, but it is a post-twentieth-century Hypnerotomachia in terms of nothing: if in fact Poliphilo loves many things (his name itself declares it), as well as Polia (another speaking name that, in fact, means many things), Nìlfilo would seem to love nothingness and his ghostly, nullifying Nìlia. A very refined dream collection, it was said, in dialogic form, The Dreams of Nìlfilo are written with a poetic prose rich in hendecasyllables with an existential-Montalian clarity and illustrated with black and white pencil drawings of extraordinary splendor. Freud passed through here (perhaps in the company of Heraclitus), and with him the trust in the irreducible uniqueness of the human subject, or rather Jung who ultimately leads everything back to the collective
Positron emission tomography in ARDS : a new look at an old syndrome
No full textThis is a review of some of the main findings obtained by positron emission tomography (PET) concerning the pathophysiology of acute respiratory distress syndrome (ARDS) and acute lung injury. PET (which is nowadays often combined with computed tomography) is a functional imaging technique based on the detection of a labeled molecule administered to a subject. Based on the molecule used, different lung functions can be imaged. Examples include inhaled, labeled nitrogen, which allows us to visualize regional aeration and ventilation, whereas lung perfusion has been studied by means of labeled water or by injected nitrogen dissolved in saline. With this latter technique, a global assessment of regional gas exchange is possible. Administration of [18F]FDG facilitates the imaging of cellular metabolic activity, reflecting an acute neutrophil-sustained inflammatory process. This technique has been used in experimental ARDS and, more recently, in patients. It showed, for example, that inflammatory activity of the lungs is markedly increased even in "normally aerated" regions at levels that are, in some cases, even higher than in the non-aerated regions
Searching for Optimal Off-Line Exploration Paths in Grid Environments for a Robot with Limited Visibility
No full textRobotic exploration is an on-line problem in which autonomous mobile robots incrementally discover and map the physical structure of initially unknown environments. Usually, the performance of exploration strategies used to decide where to go next is not compared against the optimal performance obtainable in the test environments, because the latter is generally unknown. In this paper, we present a method to calculate an approximation of the optimal (shortest) exploration path in an arbitrary environment. We consider a mobile robot with limited visibility, discretize a two-dimensional environment with a regular grid, and formulate a search problem for finding the optimal exploration path in the grid, which is solved using A*. Experimental results show the viability of our approach for realistically large environments and its potential for better assessing the performance of on-line exploration strategies
