Rodolfo Walsh en 'ese hombre': un escritor a diario, su memoria en los papeles
2013
Resumen: Este articulo integra dos tipos de lectura critica de Ese hombre y otros papeles personales (Buenos Aires, 1996 y 2007), de Rodolfo Walsh, con edicion a cargo de Daniel Link. Considerando, primero, el diario del escritor que incluye, el libro describe, dentro del pathos caracteristico del genero, las imposibilidades y los fracasos de la escritura, que especifican historicamente los problemas de la relacion entre literatura y politica, propios del campo argentino de los anos ’60-’70. Las tensiones de la escritura y la vida, agudizadas cuando apremia la militancia, y expresadas en las disyuntivas de genero –basicamente, novela vs. testimonio- constituyen, en esa linea, un eje crucia…
Representaciones de la infancia en Cuerda de presas: trazos de identidad
2014
Los sucesos de la guerra civil española y de la inmediata posguerra constituyen de un tiempo a esta parte un foco de interés para las artes, especialmente para la literatura. El conjunto de relatos allí enmarcados se convierte en un fenómeno de interés para la crítica especializada que, desde distintas perspectivas vertebradas principalmente en torno a los debates acerca de la memoria, cuestiona y aborda la representación de estos acontecimientos históricos, herida aún abierta en la sociedad española. Una forma discursiva que circula todavía por los márgenes es la historieta, y Cuerda de presas es un libro de historietas que reúne once relatos sobre la guerra civil española. En las siguient…
The relationship between health-related quality of life and melancholic depressive symptoms is modified by brain insulin receptor gene network
2021
AbstractTo investigate whether expression-based polygenic risk scores for the insulin receptor gene network (ePRS-IRs) modifiy the association between type of depressive symptoms and health-related quality of life (HRQoL). This cross-sectional study includes 1558 individuals from the Helsinki Birth Cohort Study. Between 2001 and 2004, the Short Form-36 questionnaire was employed to assess mental and physical components of HRQoL and Beck Depression Inventory (BDI) to assess depressive symptoms. Depressive symptoms were categorized into minimal (BDI < 10), non-melancholic and melancholic types of depression. The ePRS-IRs were calculated for the hippocampal (hePRS-IR) and the mesocorticolim…
DNA damage photo-induced by chloroharmine isomers: hydrolysis versus oxidation of nucleobases
2018
Photodynamic therapy (PDT) is an emerging clinical treatment currently being used against a wide range of both cancerous and noncancerous diseases. The search for new active photosensitizers as well as the development of novel selective delivery systems are the major challenges faced in the application of PDT. We investigated herein three chloroharmine derivatives (6-, 8- and 6,8-dichloroharmines) with quite promising intrinsic photochemical tunable properties and their ability to photoinduce DNA damage in order to elucidate the underlying photochemical mechanisms. Data revealed that the three compounds are quite efficient photosensitizers. The overall extent of photo-oxidative DNA damage i…
Presenting signs and patient co-variables in Gaucher disease: outcome of the Gaucher Earlier Diagnosis Consensus (GED-C) Delphi initiative.
2019
Background: Gaucher disease (GD) presents with a range of signs and symptoms. Physicians can fail to recognise the early stages of GD owing to a lack of disease awareness, which can lead to significant diagnostic delays and sometimes irreversible but avoidable morbidities. Aim: The Gaucher Earlier Diagnosis Consensus (GED-C) initiative aimed to identify signs and co-variables considered most indicative of early type 1 and type 3 GD, to help non-specialists identify ‘at-risk’ patients who may benefit from diagnostic testing. Methods: An anonymous, three-round Delphi consensus process was deployed among a global panel of 22 specialists in GD (median experience 17.5 years, collectively managin…
The Mediterranean vermetid reefs: distribution and conservation status
2016
The vermetid reef is an intertidal bioconstruction distributed in the warmest waters of the Mediterranean Sea, and is built by the gregarious vermetid gastropodDendropomaspp. cemented by the coralline red algae of the genusNeogoniolithon.Thisbiogenichabitatisonly generically protected under the European Habitat Directive, but to date it is not explicitly taken into account in many conservation plans. Despite the documented local extinction of Dendropomain the some Eastern Mediterranean locations, its role as habitat engineer and the high numbers of ecosystem services provided, vermetid reef is among the least known marine bioconstruction of the Mediterranean. We counted 112 reefs along the …
Epitaxial growth and thermoelectric properties of TiNiSn and Zr0.5Hf0.5NiSn thin films
2011
Abstract Due to their exceptional thermoelectric properties Half-Heusler alloys like MNiSn (M = Ti,Zr,Hf) have moved into focus. The growth of single crystalline thin film TiNiSn and Zr 0.5 Hf 0.5 NiSn by dc magnetron sputtering is reported. Seebeck and resistivity measurements were performed and their dependence on epitaxial quality is shown. Seebeck coefficient, specific resistivity and power factor for Zr 0.5 Hf 0.5 NiSn at room temperature were measured to be 63 μV K − 1 , 14.1 μΩ m and 0.28 mW K − 2 m − 1 , respectively. Multilayers of TiNiSn and Zr 0.5 Hf 0.5 NiSn are promising candidates to increase the thermoelectric figure-of-merit by decreasing thermal conductivity perpendicular …
Diffraction by fractal metallic supergratings.
2007
The reflectance of corrugated surfaces with a fractal distribution of grooves is investigated. Triadic and polyadic Cantor fractal distributions are considered, and the reflected intensity is compared with that of the corresponding periodic structure. The self-similarity property of the response is analyzed when varying the depth of the grooves and the lacunarity parameter. The results confirm that the response is self-similar for the whole range of depths considered, and this property is also maintained for all values of the lacunarity parameter. © 2007 Optical Society of America.

Generalized Wiener Process and Kolmogorov's Equation for Diffusion induced by Non-Gaussian Noise Source
2005
We show that the increments of generalized Wiener process, useful to describe non-Gaussian white noise sources, have the properties of infinitely divisible random processes. Using functional approach and the new correlation formula for non-Gaussian white noise we derive directly from Langevin equation, with such a random source, the Kolmogorov's equation for Markovian non-Gaussian process. From this equation we obtain the Fokker-Planck equation for nonlinear system driven by white Gaussian noise, the Kolmogorov-Feller equation for discontinuous Markovian processes, and the fractional Fokker-Planck equation for anomalous diffusion. The stationary probability distributions for some simple cas…
A Weitzenböck formula for the damped Ornstein–Uhlenbeck operator in adapted differential geometry
2001
Abstract On the Riemannian path space we consider the Ornstein–Uhlenbeck operator associated to the Dirichlet form E (f,g)=E〈 ∇ f, ∇ g〉 H , where ∇ is the damped gradient and 〈·,·〉 H the scalar product of the Cameron–Martin space H . We prove a corresponding Weitzenbock formula restricted to adapted vector fileds: the Ricci-tensor is shown to be equal to the identity.
