El cuerpo en los estudios sobre cine: gestus femenino, o tecnologías y teratologías del género y de la (pos)memoria
Authors: Ciancio Belén 
Published: January 2017

“<em>Donnez-moi donc un corps</em>!”, el grito filosófico con el que comienza el capítulo 8 de <em>L’Image-temps</em> de Gilles Deleuze, configuraría una serie de modulaciones acerca del cine moderno, del cuerpo, del cerebro y de la memoria, así como del devenir. La conjetura de este trabajo es que, a través del concepto de “tecnologías del género”, surgido desde el feminismo en los mismos años en que Deleuze publica sus libros sobre cine, se abriría una segunda línea donde el cuerpo no sólo es un concepto para la teoría, sino imagen-materia experimental en la teoría y práctica fílmica feminista así como en la teoría <em>queer</em>. Entre ambas líneas estaría el concepto de “tecnologías de la memoria” (y de la posmemoria).<div><div><p> </p></div></div>
Cuerpo, arte y escuela. El lugar del desnudo femenino en los libros de texto de ciencias sociales
Authors: Pérez Guerrero Vicente Miguel 
Published: January 2017

<p>En este trabajo nos preguntamos por cómo la enseñanza escolar del “desnudo femenino”, en el área de conocimiento de la ESO (Educación Obligatoria Secundaria), pudiera influir en la idea que los alumnos se forjan del cuerpo, de sí mismo y el de los otros. Tanto si tenemos presente que la identidad de género es siempre una identidad corporal, como que la identidad del desnudo en el Arte se asocia a la mujer, procede interrogarse por cómo se trata el desnudo femenino en los libros de texto. </p>
La tecnología de biomejora: ¿hasta dónde debemos garantizar las oportunidades de bienestar?
Authors: Campos Serena Olga 
Published: January 2017

Las biotecnologías en desarrollo tienen fuertes implicaciones más allá de los aspectos centrados en la satisfacción de ciertas necesidades individuales. Hay implicadas nuevas categorías moralmente relevantes, y tienen que ver con nuestra comprensión de la justicia distributiva, igualdad de oportunidades, nuestras obligaciones y derechos como padres, y nuestras obligaciones morales hacia los animales no humanos. Esta última cuestión es considerada particularmente determinante si demostramos que ellos son sujetos de derechos morales. Cuando intentamos determinar las prescripciones prácticas de este esquema argumentativo nos encontraremos con la obligación de analizar si las técnicas de mejora podrían ser consideradas como una herramienta para proporcionar más igualdad, dadas las situaciones naturales individuales de partida tan diferentes
Carne barroca: voluptuosidad, sumisión, sublimación
Authors: Martínez Martínez Francisco José 
Published: January 2017

Este trabajo presenta tres aspectos del cuerpo en el Barroco: el cuerpo religioso sufriente y triunfante, el cuerpo político sometido y supliciado y el cuerpo amoroso acariciado y adorado. Se trata de mostrar la ambigüedad radical del Barroco que oscila entre el apego a la vida y el culto de la muerte acabando en una tristeza resignada que sin embargo no puede dejar de mostrar cierta nostalgia respecto al sueño renacentista de afirmación de la vida, la libertad y el amor
Reinventando a Artigas: Entonces ¿mi nombre suena todavía en mi país?.
Authors: Gracia Arce Beatriz 
Published: January 2017

La figura de Artigas ha tenido un tratamiento muy diferente a lo largo del tiempo. Denostado duramente en las décadas inmediatas a la independencia y tachado por sus detractores contemporáneos de anarquista y enemigo del orden y de la propiedad, fue reivindicado como héroe nacional cuando Uruguay, hacia finales del s. XIX consolida su independencia, convirtiéndose en símbolo de la Unidad en oportunidad en que los partidos blanco y colorado que estaban enfrentados en guerras civiles. En el s. XX, coincidiendo con la consolidación de la democracia política, son puestos de relieve sobre todo los aspectos de la «Patria Vieja», pero será cuando las posturas marxistas entren en la escena cuando se reformule la imagen de Artigas. Este artículo ofrece una nueva lectura para entender su figura.
The figure of Artigas has had a very different treatment over time. Harshly reviled in the immediate decades to independence and branded by his contemporary detractors as an anarchist and an enemy of order and property, he was vindicated as a national hero when Uruguay, towards the end of the s. XIX consolidates its independence, becoming a symbol of Unity at the time that the white and red parties that were faced in civil wars. In the S. XX, coinciding with the consolidation of political democracy, the aspects of the "Old Homeland" are highlighted above all, but it will be when Marxist positions enter the scene that Artigas' image is reformulated. This article offers a new reading to understand your figure.

Published: January 2017

<p class="RESUMENCURSIVA">Este artículo es fruto de una investigación centrada en el análisis de los cibermedios desde la perspectiva de género. Se analiza la red social Facebook a través de dos temas que poseen una gran influencia en la cimentación social del concepto mujer: la gordofobia (“La gordofobia: esclavas de la belleza”) y la ruptura del concepto de mujer tradicional (“Ya no quiero ser princesa”). En un principio se examinan los antecedentes que originaron el desarrollo del movimiento cyborg, para posteriormente, estudiar el contexto en el que tuvieron lugar e indagar sobre lo que representaron en su época desde el punto de vista de la igualdad de género, y, por último, se creará una propuesta socioeducativa desde las redes sociales con el propósito de poner en cuestión los estereotipos de género en torno a la belleza y el modelo tradicional femenino.</p><p> </p>

Published: January 2017

Abstract
Heteroepitaxial BaTiO3 ferroelectric films with (001), (110), and (111) orientations were grown on SrRuO3-buffered SrTiO3 substrates by magnetron sputtering. The leakage current and interface charge behaviors were systematically investigated. Without a discernible orientation-dependence behavior, the leakage current behaviors were all well described by a modified Schottky-contact model. On the basis of this theory, the interface charge state parameters, including dynamic dielectric constant, potential barriers, depletion layer width, effective space-charge density and hole concentration, and their evolution behaviors were analyzed in detail. They all exhibited anisotropic characteristics and were proved to be essentially attributed to the macrophysical properties of BaTiO3 film heterostructures.

Published: January 2017

Abstract
Modulation of the thermal properties of graphene due to strain-induced phononic band engineering was theoretically investigated by first-principles calculations based on the density functional theory. The high-energy phonon modes are found to exhibit softening owing to the strain, whereas a low-energy acoustic mode (out-of-plane mode) exhibits hardening. Moreover, the dispersion relation of the out-of-plane mode associated with the strain essentially changes from quadratic (∝ k
2) to linear (∝ k). Accordingly, the temperature dependence of the low-temperature specific heat also changes from linear (∝ T) to quadratic (∝ T
2).
Oxygen acceleration in magnetotail reconnection

Published: January 2017

AbstractMotivated by the observed high concentration of oxygen ions in the magnetotail during enhanced geomagnetic activity, we investigated the oxygen acceleration in magnetotail reconnection by using 2.5‐D implicit particle‐in‐cell simulations. We found that lobe oxygen ions can enter the downstream outflow region, i.e., the outflow region downstream of the dipolarization fronts (DFs) or the reconnection jet fronts. Without entering the reconnection exhaust, they are accelerated by the Hall electric field. They can populate the downstream outflow region before the DFs arrive there. This acceleration is in addition to acceleration in the exhaust by the Hall and reconnection electric fields. Oxygen ions in the preexisting current sheet are reflected by the propagating DF creating a reflected beam with a hook shape in phase space. This feature can be applied to deduce a history of the DF speed. However, it is difficult to observe for protons because their typical thermal velocity in the plasma sheet is comparable those of the DF and the reflection speed. The oxygen ions from the lobes and the preexisting current sheet form multiple beams in the distribution function in front of the DF. By comparing oxygen concentrations of 50%, 5%, and 0% with the same current sheet thickness, we found that the DF thickness is proportional to the oxygen concentration in the preexisting current sheet. All the simulation results can be used to compare with the observations from the Magnetospheric Multiscale mission.

AbstractUltralow frequency (ULF) waves play an important role in the transport of the solar wind energy to the magnetosphere. In this paper, we present a ULF wave event in the dayside magnetosphere which shows a sudden decrease in frequency from 3.1 to 2.3 mHz around 0756 UT on 11 January 2010, when a solar wind dynamic pressure drop (from ∼5 to ∼2 nPa) was observed simultaneously. The wave exits globally. The phase differences between electric and magnetic fields indicate that the compressional mode wave is standing before and after the wave frequency decrease. This result suggests that the ULF wave should be associated with a cavity mode and the frequency decrease might be induced by the change of the cavity size. A theoretical calculation was made to estimate the cavity mode frequency. The calculated wave frequency before/after the negative impulse is 3.8/2.6 mHz, which is consistent with the observations.

AbstractWe characterize turbulence in the Mars plasma environment in a global scale for the first time by computing spectral indices for magnetic field fluctuations (slopes in the magnetic field power spectra) and determining how they vary with frequency and in different regions. In the magnetosheath, unlike in the solar wind, we find an absence of the inertial range which has a spectral index value equal to the Kolmogorov scaling value of −5/3. Instead, as observed in the magnetosheaths of other planets, we find that the spectral indices transition from low negative values close to −0.5 at low frequencies (< proton gyrofrequency) to values much lower than −5/3 at high frequencies (> proton gyrofrequency). This indicates that the pristine solar wind is modified at the Martian bow shock and that the fluctuations are dominated by locally generated fluctuations in the magnetosheath. The absence of spectral indices with the Kolmogorov scaling value indicates that the fluctuations in the magnetosheath do not have sufficient time to interact with one another leading to a fully developed energy cascade. Spectral index values near the Kolmogorov scaling value are observed for the low‐frequency range near the magnetic pileup boundary, and this indicates the presence of fully developed energy cascade. In the wake, we find that the spectral indices have approximately the same values, typically near −2, for both the low‐ and high‐frequency ranges. We observe seasonal variations of the spectral indices, mainly in the upstream region, which indicate the seasonal variations of the proton cyclotron waves.
Durability of alkali and heat‐treated kenaf fiber/unsaturated polyester composite fabricated by resin transfer molding under natural weathering exposure

Published: January 2017

AbstractNonwoven kenaf fiber (KF) mat‐reinforced unsaturated polyester resin composites were exposed to a natural weathering environment for 12 months. The composites were prepared using vacuum‐assisted resin transfer molding (RTM). Prior to molding, the KF mat was treated by immersing it in 6% NaOH solution for 3 hrs and by heating it at 140°C for 10 hrs, respectively. The influences of weathering exposure on the composites with respect to the different treatments were investigated using flexural properties, fracture toughness, Fourier transform infrared, thermal stability, color and scanning electron microscopy analyses. Natural weathering reduced the flexural and fracture toughness due to damage to composite structures, the formation of microcracks on the sample surface, discoloration, and chemical content alteration. A relatively better durability in terms of flexural properties was exhibited by alkali‐treated KF composites, although poor durability in fracture toughness was observed due to the improved fiber–matrix adhesion.

AbstractA biomimetic nickel bis‐diphosphine complex incorporating the amino acid arginine in the outer coordination sphere was immobilized on modified carbon nanotubes (CNTs) through electrostatic interactions. The functionalized redox nanomaterial exhibits reversible electrocatalytic activity for the H2/2 H+ interconversion from pH 0 to 9, with catalytic preference for H2 oxidation at all pH values. The high activity of the complex over a wide pH range allows us to integrate this bio‐inspired nanomaterial either in an enzymatic fuel cell together with a multicopper oxidase at the cathode, or in a proton exchange membrane fuel cell (PEMFC) using Pt/C at the cathode. The Ni‐based PEMFC reaches 14 mW cm−2, only six‐times‐less as compared to full‐Pt conventional PEMFC. The Pt‐free enzyme‐based fuel cell delivers ≈2 mW cm−2, a new efficiency record for a hydrogen biofuel cell with base metal catalysts.

Published: January 2017

AbstractA robust dynamic output feedback controller synthesis algorithm considering H∞/H2 performance and regional pole placement is addressed for a nonlinear system with parameter uncertainties and external disturbance. First, the formulation of a gain‐scheduled mixed‐objective robust dynamic output feedback controller for continuous‐time polytopic linear parameter varying (LPV) systems is presented. To reduce conservativeness, some auxiliary slack variables and parameter‐dependent Lyapunov functions are employed in addition to well‐established performance conditions. Then, sufficient conditions for the desired gain‐scheduled mixed‐objective robust dynamic output feedback controllers are cast into an efficiently tractable finite‐dimensional convex optimization problem in terms of linear matrix inequalities (LMIs). Finally, numerical simulation shows the validity of the proposed controller, which has good stability, strong robustness, satisfied disturbance attenuation ability, and smooth dynamic properties.

Published: January 2017

AbstractThe structural properties of networked control systems with both bandwidth limitations and delays are investigated. Sufficient conditions are given for controllability (stabilizability) and reconstructibility (detectability). Our results enhance previous works by capturing bandwidth limitations and delays simultaneously. The adopted modeling framework could be readily used in control and estimation methods, including optimal and predictive schemes. It also facilitates the use of scheduling optimization algorithms in conjunction with the control scheme presented.
Dissecting the Cytochrome P450 1A2‐ and 3A4‐Mediated Metabolism of Aflatoxin B1 in Ligand and Protein Contributions
Authors: Bonomo Silvia , Jørgensen Flemming Steen , Olsen Lars 
Published: January 2017

AbstractAflatoxin B1 (AFB1) is a chemically intriguing compound because it has several potential sites of metabolism (SOMs), although only some of them are observed experimentally. Cytochrome P450 (CYP) 3A4 and 1A2 are the major isoforms involved in its metabolism. Here, we systematically investigate reactivity and accessibility of all possible SOMs in these two CYPs to elucidate AFB1 metabolism. DFT calculations were used to determine activation energies for each possible reaction. Aliphatic hydroxylation on position 9A and 3α are energetically favored, whereas position 9 is the preferred site for epoxidation. Docking studies, molecular dynamics (MD) simulations, and free energy (MM/GBSA) calculations were applied to elucidate the accessibility of each SOM. The most stable binding modes in CYP3A4 favor the formation of the 3α‐hydroxylated and 8,9‐exo‐epoxide metabolites. Conversion of the methoxy group is also sterically possible, but not observed experimentally due to its low reactivity. In the CYP1A2 active site, AFB1 cannot orient position 3 towards the catalytic center, whereas the 8,9‐exo‐epoxide and 9A‐hydroxylated metabolites are formed from the most stable and the 8,9‐endo‐epoxide from a less stable binding mode, respectively. The results agree with experimental data and suggest that both reactivity and the shape of the enzyme active site need to be considered to understand the distribution of SOMs and to improve current SOM prediction methods.
Prevalence dependence in model goodness measures with special emphasis on true skill statistics
Authors: Somodi Imelda , Lepesi Nikolett , Botta‐Dukát Zoltán 
Published: January 2017

AbstractIt has long been a concern that performance measures of species distribution models react to attributes of the modeled entity arising from the input data structure rather than to model performance. Thus, the study of Allouche et al. (Journal of Applied Ecology, 43, 1223, 2006) identifying the true skill statistics (TSS) as being independent of prevalence had a great impact. However, empirical experience questioned the validity of the statement. We searched for technical reasons behind these observations. We explored possible sources of prevalence dependence in TSS including sampling constraints and species characteristics, which influence the calculation of TSS. We also examined whether the widespread solution of using the maximum of TSS for comparison among species introduces a prevalence effect. We found that the design of Allouche et al. (Journal of Applied Ecology, 43, 1223, 2006) was flawed, but TSS is indeed independent of prevalence if model predictions are binary and under the strict set of assumptions methodological studies usually apply. However, if we take realistic sources of prevalence dependence, effects appear even in binary calculations. Furthermore, in the widespread approach of using maximum TSS for continuous predictions, the use of the maximum alone induces prevalence dependence for small, but realistic samples. Thus, prevalence differences need to be taken into account when model comparisons are carried out based on discrimination capacity. The sources we identified can serve as a checklist to safely control comparisons, so that true discrimination capacity is compared as opposed to artefacts arising from data structure, species characteristics, or the calculation of the comparison measure (here TSS).
