Recensione: André Breton, Il surrealismo e la pittura, Abscondita, Milano 2010, in Rivista di studi filosofici "Syzetesis", febbraio/2011, http://www…
2011
La vicenda editoriale del saggio Il surrealismo e la pittura ripercorre in parte la biografia intellettuale di André Breton: la prima edizione del 1928, uscita per i tipi di Gallimard, è frutto di un assemblaggio di articoli che Breton pubblica sulla rivista «La Révolution surréaliste» dal luglio 1925 all'ottobre 1927. A questa prima, seguiranno altre due edizioni riviste e ampliate dallo stesso Breton: Le surréalisme et la peinture suivi de Genèse et perspective artistique du surréalisme et de fragments inédits, Brentano's, New York 1945; Le surréalisme et la peinture, Paris, Gallimard 1965 (ripubblicato recentemente nelle Œuvres complètes IV, a cura di M. Bonnet, Paris, Gallimard 2008). Q…
Confidence Intervals for the Mean Based on Exponential Type Inequalities and Empirical Likelihood
2013
For independent observations, recently, it has been proposed to construct the confidence intervals for the mean using exponential type inequalities. Although this method requires much weaker assumptions than those required by the classical methods, the resulting intervals are usually too large. Still in special cases, one can find some advantage of using bounded and unbounded Bernstein inequalities. In this paper, we discuss the applicability of this approach for dependent data. Moreover, we propose to use the empirical likelihood method both in the case of independent and dependent observations for inference regarding the mean. The advantage of empirical likelihood is its Bartlett correcta…
Sets versus trial sequences, Hausdorff versus von Mises: “Pure” mathematics prevails in the foundations of probability around 1920
2010
Abstract The paper discusses the tension which occurred between the notions of set (with measure) and (trial-) sequence (or—to a certain degree—between nondenumerable and denumerable sets) when used in the foundations of probability theory around 1920. The main mathematical point was the logical need for measures in order to describe general nondiscrete distributions, which had been tentatively introduced before (1919) based on von Mises’s notion of the “Kollektiv.” In the background there was a tension between the standpoints of pure mathematics and “real world probability” (in the words of J.L. Doob) at the time. The discussion and publication in English translation (in Appendix ) of two …
Ionic Transport through Chemically Functionalized Hydrogen Peroxide-Sensitive Asymmetric Nanopores
2015
We describe the fabrication of a chemical-sensitive nanofluidic device based on asymmetric nanopores whose transport characteristics can be modulated upon exposure to hydrogen peroxide (H2O2). We show experimentally and theoretically that the current-voltage curves provide a suitable method to monitor the H2O2-mediated change in pore surface characteristics from the electronic readouts. We demonstrate also that the single pore characteristics can be scaled to the case of a multipore membrane whose electric outputs can be readily controlled. Because H2O2 is an agent significant for medical diagnostics, the results should be useful for sensing nanofluidic devices.
Biophysical Characterization of Polysialic Acid—Membrane Nanosystems
2019
Polysialic acid (polySia) is a long, membrane-bound, polyanionic polymer (with the degree of polymerization, DP, up to 400) of negatively charged sialic acid monomers. Biological roles of polySia are based on its ability to modulate repulsive and attractive interactions, and its ability to modulate membrane surface charge density, pH at the membrane surface, and membrane potentials. PolySia is used in anti-bacterial and anti-cancer therapies, and in neural tissue repair. Hydrophobically-modified polySia chains can form nano-structures (micelles or liposomes) with high stability and low toxicity for drug delivery. The analysis, based on the Goldman-Hodgkin-Katz equation, of transmembrane pot…
Synaptic Scaling Enables Dynamically Distinct Short- and Long-Term Memory Formation
2013
Memory storage in the brain relies on mechanisms acting on time scales from minutes, for long-term synaptic potentiation, to days, for memory consolidation. During such processes, neural circuits distinguish synapses relevant for forming a long-term storage, which are consolidated, from synapses of short-term storage, which fade. How time scale integration and synaptic differentiation is simultaneously achieved remains unclear. Here we show that synaptic scaling – a slow process usually associated with the maintenance of activity homeostasis – combined with synaptic plasticity may simultaneously achieve both, thereby providing a natural separation of short- from long-term storage. The inter…
Jünger Machines and aviators. The experience of war in young Jünger's photobooks
2013
El modo en que el jünger de los años 30 recuerda y describe la guerra en sus foto-libros concibe la misma principalmente desde la contemplación estética como un espectáculo de la naturaleza, en detrimento de su cruel dimensión moral y personal. Ello, que The way in which the jünger of the 30 s remembers and describes the war in his photobooks conceives it principally since an aesthetic comprehension as a natural spectacle to the detriment of its cruel moral and personal dimension. This, which to a large e
La música preexistente en la comedia americana de los años ochenta: "Trading Places" (1983)
2009
En este trabajo se analiza el uso de la música de concierto preexistente en una de las comedias estadounidenses más interesantes de los años ochenta: "Trading Places", dirigida en 1983 por John Landis y titulada en España con el poco afortunado título de "Entre pillos anda el juego". La denominación original "Trading Places" es la que se utiliza en este trabajo puesto que define de forma más precisa la trama de la película y sirve para comprender el origen de la mayoría de la música preexistente. Landis colaboró de forma muy directa con el prestigioso compositor de bandas sonoras Elmer Bernstein, que preparó una partitura basada en música preexistente. Bernstein presenta en el filme tres ti…
Copiste et créateur : les paradoxes de l'écrivain romantique
2015
International audience; L’article analyse deux célèbres figures de copistes romantiques, celle d'Anselme, le héros du Vase d'or de Hoffmann (1814), et celle d'Akaki Akakiévitch, le héros du Manteau de Gogol (1843). Il s’interroge sur le rapport entre copie et création à l’époque romantique.
A method for the calculation of the heat transfer coefficient in potato drying
1993
A method for the determination of the heat transfer coefficient was proposed for the first falling drying period of potato cubes. During this period, heat and mass transfer were considered as coupled phenomena. Temperature calculation inside the sample was performed using the macroscopic heat transfer balance. The heat transfer coefficient was computed by means of parametric identification, using the Gauss–Newton method. The figure obtained for the heat transfer coefficient shows good agreement with other sources.
