Unlike the standard Quantum Computational Logic, where the carrier of information is conventionally assumed to be only the last qubit over a sequence of many qubits, here we propose an extended version of the QCL where the number and the position of the target qubits are arbitrary.

CHAPTER Structure and function In physical systems made by a large number of basic constituents one can observe collective properties which find their ...

We single out an alternative, strict interpretation of the Einstein-Podolsky-Rosen criterion of reality, and identify the implied extensions of quantum correlations. Then we prove that the theorem of Bell, and the non-locality theorems without inequalities, fail if the new extensions are adopted. Therefore, these theorems can be interpreted as arguments against the wide interpretation of the criterion of reality rather than as a violation of locality.

This study investigates the acquisition of integrated object manipulation and categorization abilities through a series of experiments in which human adults and artificial agents were asked to learn to manipulate two-dimensional objects that varied in shape, color, weight, and color intensity. The analysis of the obtained results and the comparison of the behavior displayed by human and artificial agents allowed us to identify the key role played by features affecting the agent/environment interaction, the relation between category and action development, and (...) the role of cognitive biases originating from previous knowledge.

A relation ≺ϕ between noncommuting 1-0 quantum observables (i.e., projections) is introduced, ϕ being the state vector of the system. This relation extends the empirical implication between commuting projections. An operational interpretation of the new relation is given, which can be expressed also in counterfactual terms. It is shown that a relation proposed some years ago by Hardegree, namely the Sasaki arrow ↪ϕ, can be interpreted in terms of the relation ≺ϕ; furthermore, this new relation turns out to be successful (...) also in cases in which the Sasaki arrow fails.

In one of his last writings, Life: Experience and Science, Michel Foucault argued that twentieth-century French philosophy could be read as dividing itself into two divergent lines: on the one hand, we have a philosophical stream which takes individual experience as its point of departure, conceiving it as irreducible to science. On the other hand, we have an analysis of knowledge which takes into account the concrete productions of the mind, as are found in science and human practices. In order (...) to account for this division, Foucault opposed epistemologists such as Cavaillès and Canguilhem to phenomenologists such as Merleau-Ponty and Sartre but, also, and more particularly, he opposed Poincaré to Bergson. The latter was presented by Foucault as being the key-figure of the ?philosophy of experience? at the beginning of the twentieth century. Fifteen years later, in his Deleuze and in the Logics of Worlds, Alain Badiou again uses this dual structure in his interpretation of the past hundred years of French thought. He employs a series of oppositional couples: himself and Deleuze, Lautmann and Sartre, and, finally, Brunschvicg and Bergson. On the one hand a ?mathematical Platonism? and on the other a ?philosophy of vital interiority.? This Manichean reading of philosophy, and the strategic use of the figure of Bergson has, itself, a long tradition. It was also proposed by Althusser who, following Bachelard, opposed his standpoint to any form of ?empiricism.? Althusser developed his thought from a tradition of Marxist thinkers and ideologists, which included Politzer's and Nizan's critique of bourgeois philosophy and, even before that, neo-Kantians such as the philosophers of the Revue de métaphysique et de morale. The aim of this essay is to deconstruct and to put into its precise context of production this series of genealogies which entails the mobilization of Bergsonism and of the name ?Bergson.? By doing so, I hope to weight the importance of Bergsonism in twentieth-century French philosophy, in both its ?positive? and its ?negative? aspect. The essay will proceed regressively, taking into account figures such as Althusser, Badiou, Deleuze, Foucault, Canguilhem, Cavaillès, Sartre, Merleau-Ponty, but also Polizer, Brunschvicg and Alain. The conclusion of the essay is an attempt at reading the ?Bergson renaissance? in the light of new discoveries in genetics and the cognitive sciences and to tie it to the renewal of studies in the history of French philosophy.

Nel pensiero politico di Ralf Dahrendorf un tema ricorre costantemente, sia che si tratti di liberalismo sia della democrazia rappresentativa: le costituzioni politiche sono radicate nelle strutture sociali, stato politico e stato sociale sono mutualmente interdipendenti. In assenza di specifiche strutture sociali, la democrazia rappresentativa non può divenire effettiva, e quindi corrispondere a una realtà evidente perfettamente valutabile. Ancora. Le strutture sociali pongono limiti molto ristretti all’effettività delle forme politiche. Esistono, in altri termini, precisi elementi strutturali che permettono l’oggettivazione della (...) democrazia liberale, e non altri. Si tratta certo di una concezione che deve molto a Tocqueville, la sua immagine illumina il pensiero dahrendorfiano sulla democrazia. Pur tuttavia non è l’unico elemento ricorrente. Ideale e reale qui si confrontano. L’idea di democrazia, infatti, si misura con la realtà sul terreno della prassi politica. Non a caso Ralf Dahrendorf è presente in quattro diversi parlamenti in cui ha visto all’opera il cambiamento senza violenza, l’argomentazione razionale, l’espressione della maggioranza e il controllo del governo. Non si tratta solo dei princìpi fondamentali della teoria politica democratica, ma anche della sua formula politica, con la quale interpreta i cambiamenti negli spazi politici globali. Si tratta di spazi nei quali il potere è libero da vincoli, si misura sulla base di rapporti di forza, non conosce regole e procedure se non quelle dell’economicismo, della tecnica, della finanziarizzazione. Tuttavia lo Stato nazionale e la democrazia parlamentare sono ancora decisivi. Proprio perché pensa questo, egli crede che nello spazio globale i principi della democrazia rappresentativa devono essere tradotti in realtà. Certo, Dahrendorf non è in grado di indicare nuove soluzioni, ma si limita a mostrare delle semplici proposte per gestire il dibattito pubblico nel passaggio da una democrazia classica ad una «nuova democrazia».

Il volume raccoglie diversi saggi su teologi ambrosiani dei decenni centrali del XX secolo.

The view that short-term memory should be conceived of as being a process based on the activation of long-term memory is inconsistent with neuropsychological evidence. Data from brain-damaged patients, showing specific patterns of impairment, are compatible with a vision of memory as a multiple-component system, whose different aspects, in neurologically unimpaired subjects, show a high degree of interaction.

Adriana Zarri, teóloga y eremita italiana, vivió profunda y activamente el contexto eclesial posterior al Concilio Vaticano II. Entre los aspectos distintivos de su pensamiento y su estilo de vida se destaca una profunda relación con la naturaleza. Es su “espiritualidad del jardín”, que nació de su experiencia en los eremitorios que habitó. Para Zarri, la hierba, las flores y los frutos del huerto son medios de comunicación con Dios y formas de conocerlo más profundamente. De esta conexión con los (...) elementos naturales surgen diversas formas de oración, que se convierten en vehículos de su pensamiento teológico. La sistematización de estos contenidos se entrelaza con Laudato si', para resaltar el carácter profético de su pensamiento. (shrink)

A case situation arising in a normal interaction among people is the baseline for discussing properties of the theory of viewpoints. In particular we consider how to ensure agreement on the meaning of certain utterances by agents who have different perspectives on the situation, while maintaning other knowledge as private. We argue that communication should be modeled as adding facts to the common knowledge of agents. We introduce the principle of ''referent sharing'' in communications and argue that common knowledge resulting (...) from communication should only use constants whose referent is manifest to the parties involved.

The progressive unraveling over the past fifteen years of the structure and function of the human mitochondrial genome, taken as a prototype of all vertebrate mitochondrial genomes, has been marked by a series of startling discoveries. The history of these developments is one in which prediction often turned out to be wrong, and in which solidly established dogmas were violated. The unique features of this genome have forced a revision of our ideas about the universality of the genetic code and (...) of the decoding mechanism, the minimal structural requirements for rRNA, tRNA and mRNA function and the mode and control of gene expression.
