Falsa acusación y teatralidad en «Laura perseguida» de Lope de Vega

Laura perseguida is one of the oldest comedias written by Lope de Vega. We study in this article the generic indecision which characterizes this play, as it often occurs in this phase of the story of the Comedia nueva. Another remarkable characteristic of this play is the importance of the false accusation, which is a part of the vaster theme of the the problematic identity of the central character.Laura perseguida es una de las más antiguas comedias de Lope de Vega que se hayan conservado. Se estudia aquí la indecisión genérica que caracteriza a esta comedia y que es frecuente en la producción teatral de esa época. También es notable en Laura perseguida la importancia que se le confiere al motivo de la falsa acusación (aquí de la heroína) que se enmarca en la temática más general, y definitoria de la comedia palatina, de la ocultación de identidad, que da lugar en esta comedia a una escena de teatro dentro del teatro de múltiples consecuencias

La disonancia genérica en la comedia palatina temprana : el ejemplo de «Laura perseguida» (1594)

Laura perseguida es considerada generalmente como una comedia palaciega, pero la mezcla de características cómicas y trágicas hace difícil su definición precisa. Este artículo trata de medir en primer lugar hasta qué punto se realiza la mezcla tragicómica. Luego, en la medida en que Laura perseguida, una de las primeras comedias de Lope de Vega que se conservan, fue escrita antes de la difusión de la Poética en España, se propone una lectura no aristotélica de esta comedia. Concebida como soporte de una futura representación, Laura perseguida, como muchas otras palatinas tempranas, otorga al actor un lugar central, y puede compararse a una partitura operística que permite destacar el virtuosismo técnico de los actores.Laura perseguida is generally regarded as a palatine comedy, but the mixture of comic and tragic characteristics makes it difficult to define precisely. This article attempts to measure the extent to which the tragic-comic mix is achieved. Secondly, insofar as Laura perseguida, one of Lope de Vega's earliest comedies, was written before the circulation of Poetics in Spain, a non-Aristotelian reading of this comedia is proposed. Conceived as a support for a future performance, Laura perseguida, like many other early palatine comedias, gives the actor a central place, and can be compared to an opera score allowing the technical virtuosity of the actors to be highlighted

Chapter Sobre el papel de Lope de Vega en la construcción del relato nacional del clasicismo francés

This essay deals with an aspect of the formation process of the image of the Spanish Baroque theatre in France as an irregular and chaotic aesthetic form, which was also considered inferior with respect to the French classical model. In this theoretical construction, Lope de Vega embodies all of the Spanish theatre's flaws and, more generally, Hispanic literature's ones, in turn conceived as an expression of the Spanish nation’s spirit. This process of elaborating an image of an author at the service of the invention of a national stereotype is possible thanks to the early reception of some prose works by Lope (La Arcadia, El peregrino en su patria) which are enjoying a widespread diffusion in their translations. In a context marked by controversy surrounding the tragi-comédie, assimilated by his detractors to a simple theatrical deformation of novelistic material, Lope de Vega assumes the function of representative of a literature considered extraneous to any rule and to the separation between literary genres

‘La vida es sueño’ leída desde el desenlace

Estudio las estructuras dramáticas de ‘La vida es sueño’ y en particular de la mal llamada intriga secundaria construida en torno al personaje de Rosaura. La presencia de motivos propios de la comedia de enredo en esta tragedia, y la semejanza del sistema dramático con el que a menudo se encuentra en la comedia de burlador se explica merced a una lectura hacia atrás, es decir a partir del desenlace. El casamiento entre Segismundo y Estrella, lejos de ser un accidente o una convención propia de los finales felices, se considera aquí como el elemento fundamental de la inventio calderoniana, al que necesariamente tienen que llevar las distintas partes de la acción, y así se explica la función y la trayectoria de Rosaura / The present work studies the dramatic structures of La vida es sueño, focusing on the inaptly called «secondary intrigue» constructed around the character of Rosaura.The presence of motives typical of the comedy of intrigue within this tragedy, moreover the fact that the dramatic system is similar to the system quite often found in the «comedia de burlador», can be explained by a lecture directed backwards, that is to say, beginning from the ending.The marriage of Segismundo and Estrella, which is far from being a coincidence or a convention typical of a happy ending, is considered a fundamental element of the Calderonean inventio to which all the different parts of the tragedy necessarily have to lead, and this is how to explain the function and development of Rosaura

ISAR imaging Based on the Empirical Mode Decomposition Time-Frequency Representation

International audienceThis work proposes an adaptation of the Empirical Mode Decomposition Time-Frequency Distribution (EMD-TFD) to non-analytic complex-valued signals. Then, the modified version of EMD-TFD is used in the formation of Inverse Synthetic Aperture Radar (ISAR) image. This new method, referred to as NSBEMD-TFD, is obtained by extending the Non uniformly Sampled Bivariate Empirical Mode Decomposition (NSBEMD) to design a filter in the ambiguity domain and to clean the Time-Frequency Distribution (TFD) of signal. The effectiveness of the proposed scheme of ISAR formation is illustrated on synthetic and real signals. The results of our proposed methods are compared to other Time-Frequency Representation (TFR) such as Spectrogram, Wigner-Ville Distribution (WVD), Smoothed Pseudo Wigner-Ville Distribution (SPWVD) or others methods based on EMD

Angiotensin II and tumour necrosis factor α as mediators of ATP-dependent potassium channel remodelling in post-infarction heart failure

Aims Angiotensin II (Ang II) and tumour necrosis factor α (TNFα) are involved in the progression from compensated hypertrophy to heart failure. Here, we test their role in the remodelling of ATP-dependent potassium channel (KATP) in heart failure, conferring increased metabolic and diazoxide sensitivity. Methods and results We observed increased expression of both angiotensinogen and TNFα in the failing rat myocardium, with a regional gradient matching that of the KATP subunit Kir6.1 expression. Both angiotensinogen and TNFα expression correlated positively with Kir6.1 and negatively with Kir6.2 expression across the post-infarction myocardium. To further identify a causal relationship, cardiomyocytes isolated from normal rat hearts were exposed in vitro to Ang II or TNFα. We observed increased Kir6.1 and SUR subunit and reduced Kir6.2 subunit mRNA expression in cardiomyocytes cultured with Ang II or TNFα, similar to what was observed in failing hearts. In patch-clamp experiments, cardiomyocytes cultured with Ang II or TNFα exhibited responsiveness to diazoxide, in terms of both KATP current and action potential shortening. This was not observed in untreated cardiomyocytes and resembles the diazoxide sensitivity of failing cardiomyocytes that also overexpress Kir6.1. Ang II exerted its effect through induction of TNFα expression, because TNFα-neutralizing antibody abolished the effect of Ang II, and in failing hearts, regional expression of angiotensinogen matched TNFα expression. Finally, Ang II and TNFα regulated KATP subunit expression, possibly through differential expression of Forkhead box transcription factors. Conclusion This study identifies Ang II and TNFα as mediators of the remodelling of KATP channels in heart failur

REFROIDISSEMENT MOLECULAIRE INDUIT PAR CHAMP ELECTRIQUE ; MISE EN EVIDENCE PAR SPECTROSCOPIE NON LINEAIRE CARS

National audienceNous avons montré qu'un refroidissement moléculaire pouvait être induit par un champ électrique statique appliqué à des molécules non polaires d'huile de paraffine. Cet effet a été mis en évidence grâce à une mesure de spectroscopie CARS (Coherent Anti-Stokes Raman Scattering). De manière complémentaire, l'exposition de molécules à un champ électrique permet de contrôler leur orientation et ainsi améliorer ou diminuer l'amplitude de leur signature vibrationnelle

Dans ce cadre, un code de simulation numérique a été développé avec l’aide des méthodes Level Set et Ghost Fluid afin de prédire les efforts mécaniques exercés sur une paroi biologique lors du collapse et l’implosion de bulles de cavitation engendrés par une onde acoustique ultrasonore

High Accuracy 65nm OPC Verification: Full Process Window Model vs. Critical Failure ORC

It is becoming more and more difficult to ensure robust patterning after OPC due to the continuous reduction of layout dimensions and diminishing process windows associated with each successive lithographic generation. Lithographers must guarantee high imaging fidelity throughout the entire range of normal process variations. The techniques of Mask Rule Checking (MRC) and Optical Rule Checking (ORC) have become mandatory tools for ensuring that OPC delivers robust patterning. However the first method relies on geometrical checks and the second one is based on a model built at best process conditions. Thus those techniques do not have the ability to address all potential printing errors throughout the process window (PW). To address this issue, a technique known as Critical Failure ORC (CFORC) was introduced that uses optical parameters from aerial image simulations. In CFORC, a numerical model is used to correlate these optical parameters with experimental data taken throughout the process window to predict printing errors. This method has proven its efficiency for detecting potential printing issues through the entire process window [1]. However this analytical method is based on optical parameters extracted via an optical model built at single process conditions. It is reasonable to expect that a verification method involving optical models built from several points throughout PW would provide more accurate predictions of printing errors for complex features. To verify this approach, compact optical models similar to those used for standard OPC were built and calibrated with experimental data measured at the PW limits. This model is then applied to various test patterns to predict potential printing errors. In this paper, a comparison between these two approaches is presented for the poly layer at 65 nm node patterning. Examples of specific failure predictions obtained separately with the two techniques are compared with experimental results. The details of implementing these two techniques on full product layouts are also included in this study
