Hedwig and The Angry Inch: el Plató més alternatiu

L'objectiu d'aquest article és mostrar com un mite antic, el mite dels tres gèneres, també anomenat de l'androgin de l'Aristòfanes del Simposi de Plató, esdevé per a John Cameron Mitchell la imatge adient per a explicar l'especial personalitat d'un home, Hedwig, que esdevé mitjançant una operació un androgin imperfecte, però que simbolitza la possibilitat d'una humanitat unida o l'acostament de móns diferents, de la mateixa manera que ell va pertànyer a les dues Berlín dividides per un mur que ara ja ha caigut, quedant restablerta així la unitat perduda.

New York versus la tragedia y Edipo. El legado sofocleo -y sofístico- en Crimes and Misdemeanors de W. Allen

Más allá de la referencia explícita a la tragedia griega y Edipo, el objetivo de este artículo es presentar la estrecha relación, en opinión del autor, entre lo que mantienen los protagonistas en Crimes and Misdemeanors y las teorías de los sofistas griegos sobre Dios, la ley, etc. Una confrontación minuciosa de sus textos con el guión de la película revela claramente unas raíces sofísticas que no pueden ser atribuidas, en este caso, a la presencia constante del legado judío en la obra de W. Allen.

Albert Lewin: Pandora y el Holandés Errante. La potencialidad semiológica de un mito griego

Albert Lewin, conocido director de cine de Hollywood influenciado por el movimiento surrealista, une el mito de Pandora con la leyenda del Holandés errante para crear una historia de amor ejemplar, una historia de amor loco que va más allá de los límites de la racionalidad. Y, como que para creer en este tipo de amor no es la razón stricto sensu la que nos ha de guiar, construye un mundo de signos, un mundo semiológico complejo que este artículo ayuda a descifrar.

Albert Lewin: Pandora i l'Holandès Errant. La potencialitat semiològica d'un mite grec

Albert Lewin, conegut director de cinema de Hollywood influenciat pel moviment surrealista, conjumina el mite de Pandora amb la llegenda de l'Holandès errant per crear una història d¿amor exemplar, una història d¿amor foll que va més enllà del límits de la racionalitat. I, com que per creure en aquest tipus d'amor no es la raó stricto sensu la que ens ha de guiar, basteix tot un món de signes, un món semiològic complex que aquest article ajuda a desxifrar.

Albert Lewin. Pandora and the Flying Dutchman: the Semiologic Potential of a Greek Myth

Albert Lewin, a well-known Hollywood cinema director who is significantly influenced by the surrealistic movement, brings together the myth f Pandora and the legend of the flying Dutchman in order to create an exemplary love story, a crazy love story which goes beyond the limits of human reason. Bearing in mind, then, that if one wants to believe in this sort of love story must not be guided by human reason stricto sensu, he builds a world of signs, a semiologic world which this article aims at helping to interpret.

Hedwig and The Angry Inch: el Platón más alternativo

El objetivo de este artículo es mostrar cómo un mito antiguo, el mito de los tres géneros, también llamado del andrógino del Aristófanes del Simposio de Platón, deviene para John Cameron Mitchell la imagen idónea para explicar la personalidad especial de un hombre, Hedwig, que se convierte mediante una operación en un andrógino imperfecto, pero que simboliza la posibilidad de una humanidad unida o el acercamiento de mundos diferentes, al igual que él perteneció a las dos Berlín divididas por un muro que ahora ya ha caído, restableciéndose así la unidad perdida.

Hedwig and The Angry Inch: Plato at the Sundance Film Festival

The aim of this article is to show how an ancient myth, that of the three genres, also known as the myth of the androgynous by Aristophanes in Plato¿s Symposium, becomes for John Cameron Mitchell the suitable image in order to explain the peculiar personality of a man, Hedwig, who by means of a surgical operation becomes in his turn an imperfect androgynous but symbolises the need of a sole mankind or the unity of different worlds, just as he belonged to both Berlins divided by an already fallen wall, which permitted their inhabitants to recover their lost unity and identity.

New York versus Tragedy and Oedipus. The Legacy of Sophocles and the Sophists in Woody Allen's "Crimes and Misdemeanors"

Beyond the explicit reference to the Greek tragedy and Oedipus, the aim of this article is to show the clear relationship, in the author's opinion, between what the protagonists of the film maintain and the theories of the Greek Sophists about God, the law, etc. An accurate analysis both of their texts and the screenplay of Crimes and Misdemeanors reveals different sophistic roots, which, in this case, cannot be attributed to the constant presence of the Jewish legacy in W. Allen's work.

New York versus la tragèdia i Èdip. El llegat de Sòfocles -i dels sofistes- a Crimes and Misdemeanors de W. Allen

Més enllà de la referència explícita a la tragèdia grega i Èdip, l'objectiu d'aquest article és presentar l'estreta relació, en opinió del autor, entre allò que mantenen els protagonistes a Crimes and Misdemanors i les teories del sofistes grecs sobre Déu, la llei, etc. Una confrontació acurada dels seus textos amb el guió de la pel·lícula revela clarament unes arrels sofístiques que no poden ser atribuïdes, en aquest cas, a la constant presència del llegat jueu en l'obra de W. Allen.

Film-free laser forward printing of transparent and weakly absorbing liquids

A laser-based technique for printing transparent and weakly absorbing liquids is developed. Its principle of operation relies in the tight focusing of short laser pulses inside the liquid and close to its free surface, in such a way that the laser radiation is absorbed in a tiny volume around the beam waist, with practically no absorption in any other location along the beam path. If the absorbed energy overcomes the optical breakdown threshold, a cavitation bubble is generated, and its expansion results in the propulsion of a small fraction of liquid which can be collected on a substrate, leading to the printing of a microdroplet for each laser pulse. The technique does not require the preparation of the liquid in thin film form, and its forward mode of operation imposes no restriction concerning the optical properties of the substrate. These characteristics make it well suited for printing a wide variety of materials of interest in diverse applications. We demonstrate that the film-free laser forward printing technique is capable of printing microdroplets with good resolution, reproducibility and control, and analyze the influence of the main process parameter, laser pulse energy. The mechanisms of liquid printing are also investigated: time-resolved imaging provides a clear picture of the dynamics of liquid transfer which allows understanding the main features observed in the printed droplets.

Magnetic structure of Li2CuO2: From ab initio calculations to macroscopic simulations

The magnetic structure of the edge-sharing cuprate compound Li2CuO2 has been investigated with highly correlated ab initio electronic structure calculations. The first- and second-neighbor in-chain magnetic interactions are calculated to be 142 and -22 K, respectively. The ratio between the two parameters is smaller than suggested previously in the literature. The interchain interactions are antiferromagnetic in nature and of the order of a few K only. Monte Carlo simulations using the ab initio parameters to define the spin model Hamiltonian result in a Nel temperature in good agreement with experiment. Spin population analysis situates the magnetic moment on the copper and oxygen ions between the completely localized picture derived from experiment and the more delocalized picture based on local-density calculations.

Many worlds in one

A generic prediction of inflation is that the thermalized region we inhabit is spatially infinite. Thus, it contains an infinite number of regions of the same size as our observable universe, which we shall denote as O regions. We argue that the number of possible histories which may take place inside of an O region, from the time of recombination up to the present time, is finite. Hence, there are an infinite number of O regions with identical histories up to the present, but which need not be identical in the future. Moreover, all histories which are not forbidden by conservation laws will occur in a finite fraction of all O regions. The ensemble of O regions is reminiscent of the ensemble of universes in the many-world picture of quantum mechanics. An important difference, however, is that other O regions are unquestionably real.

Quantum black hole entropy and newton constant renormalization

ty that low-energy effective field theory could be sufficient to understand the microscopic degrees of freedom underlying black hole entropy. We propose a qualitative physical picture in which black hole entropy refers to a space of quasicoherent states of infalling matter, together with its gravitational field. We stress that this scenario might provide a low-energy explanation of both the black hole entropy and the information puzzle.

Absence of epidemic threshold in scale free networks with degree correlations

Random scale-free networks have the peculiar property of being prone to the spreading of infections. Here we provide for the susceptible-infected-susceptible model an exact result showing that a scale-free degree distribution with diverging second moment is a sufficient condition to have null epidemic threshold in unstructured networks with either assortative or disassortative mixing. Degree correlations result therefore irrelevant for the epidemic spreading picture in these scale-free networks. The present result is related to the divergence of the average nearest neighbors degree, enforced by the degree detailed balance condition.
