Quantum cellular automata and quantum walks provide a framework for the foundations of quantum field theory, since the equations of motion of free relativistic quantum fields can be derived as the small wave-vector limit of quantum automata and walks starting from very general principles. The intrinsic discreteness of this framework is reconciled with the continuous Lorentz symmetry by reformulating the notion of inertial reference frame in terms of the constants of motion of the quantum walk dynamics. In particular, among the (...) symmetries of the quantum walk which recovers the Weyl equation—the so called Weyl walk—one finds a non linear realisation of the Poincaré group, which recovers the usual linear representation in the small wave-vector limit. In this paper we characterise the full symmetry group of the Weyl walk which is shown to be a non linear realization of a group which is the semidirect product of the Poincaré group and the group of dilations.

ABSTRACT This article describes the digital critical edition of the works and letters of Nietzsche published by Nietzsche Source compared with the different versions of the Colli/Montinari critical edition.

Im Mittelpunkt des Bandes steht mit Nietzsches Nachlass derjenige Teil seines Schaffens, von dem seit jeher eine besondere Faszination ausging. Sein Status ist bis heute höchst umstritten. Handelt es sich bei den nachgelassenen Aufzeichnungen um Skizzen und Vorstufen, um Bausteine für neue Werke oder gar – wie etwa Martin Heidegger meinte – um das ‚eigentliche‘ Werk Nietzsches? Außer Frage steht, dass der Nachlass besondere editorische und interpretatorische Schwierigkeiten aufwirft. Zugleich herrscht aber weitgehender Konsens darüber, dass er für das Verständnis von (...) Nietzsches Denken und Schreiben unverzichtbar ist, denn viele seiner zentralen Gedanken sind im Nachlass anders, mitunter scheinbar deutlicher, bisweilen überhaupt nur hier formuliert. Die Beiträge gehen diesen Spannungsverhältnissen nach, indem sie sowohl am Beispiel konkreter Einzelfälle als auch grundsätzlich den angemessenen Umgang mit Nietzsches nachgelassenen Schriften diskutieren.

In this paper we review the general framework of operational probabilistic theories, along with the six axioms from which quantum theory can be derived. We argue that the OPT framework along with a relaxed version of five of the axioms, define a general information theory. We close the paper with considerations about the role of the observer in an OPT, and the interpretation of the von Neumann postulate and the Schrödinger-cat paradox.

The theme of the relationship between art and society is certainly not a central topic in the aesthetic reflection of Italian neo-idealism. Neither in Croce nor in Gentile it is ever discussed at length, and the few writings in which it is addressed are brief and polemically oriented. This essay, however, proposes to discuss the few hints present in Croce and Gentile on this subject. First, the debate on the materialistic interpretation of history will be examined, to which both Croce (...) and Gentile made important contributions at the end of the 19th century. Secondly, Croce’s own way of doing the history of literature will be discussed, showing the differences that distance him from the Desanctisian model and also from the model derived from the Hegelian Aesthetics. Croce’s way of making history of literature, indeed, aroused harsh criticism after World War II and provoked a request for a “return to De Sanctis”.Finally, but the theme will be only hinted at in the essay, a brief reference will be proposed to the opinions of Antonio Gramsci and his reading of Croce.

Fino a vent’anni fa il nome di Solger, uno dei pensatori più significativi del Romanticismo tedesco, certo il più sistematico e filosoficamente attrezzato tra i protagonisti di quella grande stagione, era noto in Italia, anche fra gli studiosi di estetica, quasi soltanto per la menzione che delle sue teorie viene fatta nelle Lezioni di Estetica di Hegel. Nel giro di pochi anni, però, la situazione è radicalmente cambiata. Sono state tradotte le sue Lezioni di estetica, apparse postume nel 182...

The paper aims at proposing an extended notion of epigenesis acknowledging an actual causal import to the phenotypic dimension for the evolutionary diversification of life forms. “Introductory remarks” section offers introductory remarks on the issue of epigenesis contrasting it with ancient and modern preformationist views. In “Transmutation of forms: phenotypic variation, diversification, and complexification” section we propose to intend epigenesis as a process of phenotypic formation and diversification dependent on environmental influences, independent of changes in the genomic nucleotide sequence, and (...) occurring during the whole life span. Then, “Evolvability and phenotypic evolution” section focuses on phenotypic plasticity and offers an overview of basic properties that allows biological systems to be evolvable—i.e. to have the potentiality of producing phenotypic variation. Successively, the emphasis is put on environmentally-induced modifications in the regulation of gene expression giving rise to phenotypic variation and diversification. After some brief considerations on the debated issue of epigenetic inheritance, the issue of culture is considered. The key point is that, in the case of humans and of the evolutionary history of the genus Homo at least, the environment is also, importantly, the cultural environment. Thus, “Bio-cultural feedback” section argues that a bio-cultural feedback should be acknowledged in the “epigenic” processes leading to phenotypic diversification and innovation in Homo evolution. Finally, “Brain plasticity and cultural neural reuse” section introduces the notion of “cultural neural reuse”, which refers to phenotypic/neural modifications induced by specific features of the cultural environment that are effective in human cultural evolution without involving genetic changes. Therefore, cultural neural reuse may be regarded as a key instance of the bio-cultural feedback and ultimately of the extended notion of epigenesis proposed in this work. (shrink)

Apoptotic pathways have always been regarded as a key‐player in preserving tissue and organ homeostasis. Excessive activation or resistance to activation of cell death signaling may indeed be responsible for several mechanisms of disease, including malignancy and chronic degenerative diseases. Therefore, targeting apoptotic factors gained more and more attention in the scientific community and novel strategies emerged aimed at selectively blocking or stimulating cell death signaling. This is also the case for the TMEM219 death receptor, which is activated by a (...) circulating ligand, the Insulin‐like growth factor binding protein 3 (IGFBP3) and induces a caspase‐8‐dependent apoptosis of the target cells. Interestingly, stimulation of the IGFBP3/TMEM219 axis exerts an anti‐proliferative effect, while blockade of the TMEM219 deleterious signal protects TMEM219‐expressing cells of the endocrine pancreas, lung, and intestine from damage and death. Here, we summarize the most updated reports on the role of the IGFBP3/TMEM219 apoptotic axis in disease conditions, including intestinal disorders and diabetes, and we describe the advancements in designing and testing novel TMEM219‐based targeting approaches in emerging potential clinical applications.

Bernard Berenson used to refer to Giovanni Morelli as «the founder of the Method». With these words, he meant that Morelli was the scholar who, first, transformed connoisseurship in a science, giving to the discipline a stringent method. Does Morelli’s theory of painting really deserve this praise? To answer this question, this paper examines in the first part the philosophical and scientific background of Morelli’s doctrine, showing how its original debt payed to romantic philosophy went replaced by a neat positivist (...) orientation. In the second part, the Method itself is discussed, asking in which measure it was anticipated by the intuitions of art experts such as Giulio Mancini or Luigi Crespi and discussing the nature and epistemological relevance of the so-called “morellian details”, that is the forms of the nails, of the ears, of the hair’s curls in paintings. Are these details really sufficient for the attribution of a painting to an artist? Which role play the documents in connoisseurship? And, more generally, how important is aesthetic value in the morellian “Method”? (shrink)

After a few general observations on scientific activity, the author briefly comments on different versions of naturalism. Subsequently, he suggests that the birth of evolutionary biology and its successive developments may show how the natural world comes to be differently conceived as scientific advancements are accomplished. Then the main thesis is outlined by introducing the principles of a heuristic science-based naturalism not conclusively defining the real and the knowable. From the epistemological perspective, heuristic naturalism is meant to be framed in (...) critical realism, whereas from the ontological standpoint it may be framed in emergent monism, given that the latter can also underpin recent trends in investigation addressing human specificity. Finally, attention is turned to some implications of heuristically guided scientific activity with regard to the issues of divine action and of imago Dei. (shrink)

This article puts forward some observations about the literary form of Documentalità. The genre to which Documentalità belongs is undoubtedly the philosophical treatise. This is a novelty, because the philosophical treatise is not a popular literary form with contemporary philosophers. But it is a genre that proves to be functional in the project of philosophical reconstruction pursued by Ferraris, and that do not necessarily conflict with the Derridean roots from which Documentality moves.

Der Band verzeichnet erstmals sämtliche Werke und Noten aus Nietzsches persönlicher Bibliothek (BN) bis Anfang Januar 1889. Er listet sowohl die Bestände der Herzogin Anna Amalia Bibliothek als auch die des Goethe- und Schiller-Archivs in Weimar auf. Die kritische Analyse anderer Bestandslisten ermittelte zudem zahlreiche heute nicht mehr vorhandene Titel. Ferner wurden sämtliche Bücherrechnungen und -quittungen von Buchhändlern und Buchbindern ausgewertet, die im Goethe- und Schiller-Archiv aufbewahrt werden. Neben den ca. 2.200 Titeln aus Nietzsches rekonstruierter Bibliothek enthält der Band auch (...) ein Verzeichnis sämtlicher 'Lesespuren' Nietzsches (ca. 20.000), z.B. Anmerkungen, Unterstreichungen und Eselsohren. Ergänzt durch zahlreiche Faksimile-Reproduktionen sowie durch philosophische, historische und bibliographische Einführungen, stellt der Band ein unverzichtbares Arbeitsinstrument jeder zukünftigen Nietzsche-Forschung dar.
