Criticality of environmental information obtainable by dynamically controlled quantum probes Zwick, Analía Elizabeth; Alvarez, Gonzalo Agustin; Kurizki, Gershon A universal approach to decoherence control combined with quantum estimation theory reveals a critical behavior, akin to a phase transition, of the information obtainable by a qubit probe concerning the memory time of environmental fluctuations of generalized Ornstein-Uhlenbeck processes. The criticality is intrinsic to the environmental fluctuations but emerges only when the probe is subject to suitable dynamical control aimed at inferring the memory time. A sharp transition is anticipated between two dynamical phases characterized by either a short or long memory time compared to the probing time. This phase transition of the environmental information is a fundamental feature that characterizes open quantum-system dynamics and is important for attaining the highest estimation precision of the environment memory time under experimental limitations.

Physical and mechanical properties of raspberries subjected to osmotic dehydration and further dehydration by air- and freeze-drying Sette, Paula Andrea; Salvatori, Daniela Marisol; Schebor, Carolina Claudia The aim of this study was to analyze the effect of the application of dry and wet sucrose infusions, as pretreatments previous to air- and freeze-drying, on mechanical and physical properties of raspberries: water sorption, glass transition temperature (Tg), molecular mobility, texture and rehydration properties. Different dry and wet sugar infusions were prepared using combinations of additives: sodium bisulphite, citric acid, sodium bisulphite and citric acid, and no additives. These specific pretreatments are often used to obtain better sensorial characteristics of fruits upon further drying. After the dehydration step (air- or freeze-drying), all the samples were in the supercooled state. Pretreated samples presented lower Tg values and lower spin–spin relaxation times than control samples. Regarding texture, pretreated samples showed lower firmness than control samples. Also, freeze-dried pretreated samples showed higher firmness and lower deformability than air-dried pretreated ones. When considering the hygroscopicity, freeze-dried samples were more hygroscopic than air-dried ones. The fresh-like dried raspberries obtained could be directly consumed as snacks or incorporated in a composite food, such as a cereal mix. In this latter case, pretreated fruits would be more suitable, since their rehydration capacity at short times was relatively low.

Gallbladder cancer: South American experience Arroyo, Gerardo F.; Gentile, Alberto; Parada, Luis Antonio Large differences in terms of incidence and mortality due to gallbladder cancer (GBC) have been reported worldwide. Moreover, it seems that GBC has unique characteristics in South America. We surveyed the literature looking for information about the epidemiology, basic and translational research, and clinical trials performed in South America in order to critically analyze the magnitude of this health problem in the region. Compared to other geographic areas, age-standardized mortality rates (ASMR) for GBC in women are very high, particularly in many western areas of South America. Genetic, as well as dietary and environmental factors likely contribute to the pathogenesis of this disease in the area. Compared to other regions the profile of abnormalities of key genes such as KRAS and TP53 in GBC seems to slightly differ in South America, while the clinical behavior appears to be similar with a median overall survival (OS) of 6.5 to 8 months in advanced GBC. In contrast to Europe and USA, prophylactic cholecystectomy is a common practice in western areas of South America. GBC particularly affects women in South America, and represents a significant public health problem. It appears to have peculiarities that pose an urgent need for additional research aimed to discover risk factors, molecular events associated with its development and new treatment options for this lethal disease.

Una técnica robusta para modelar el rompimiento de la estela vorticosa en generadores eólicos de gran potencia y eje horizontal Gomez, Cynthia Noelia; Preidikman, Sergio; Lopez Mejia, Omar D.; Roccia, Bruno Antonio Con el fin de aumentar el conocimiento del comportamiento aerodinámico de turbinas eólicas de eje horizontal y de gran potencia y lograr así un correcto diseño de las mismas, los estudios aerodinámicos, aeroelásticos y aeroservoelásticos de estos sistemas de generación de energías limpias han recobrado interés durante los últimos años. En este trabajo se presenta el desarrollo e implementación computacional de un nuevo método de simulación del fenómeno de ruptura de las estelas vorticosas generadas por las palas al impactar la torre portante; dicha componente influye de manera directa en el comportamiento de la potencia mecánica de la turbina. La nueva técnica numérica se implementó en un código computacional ya existente, basado en una versión modificada del método de red de vórtices no lineal y no estacionario. Con el objetivo de poner en evidencia la eficiencia y robustez del nuevo método de ruptura, se comparan los resultados numéricos con un esquema desarrollado con anterioridad. Además, se analiza cualitativamente la forma de la ruptura al variar el número de elementos aerodinámicos utilizados para discretizar las palas y la torre. Finalmente, para analizar cuantitativamente la influencia de la discretización aerodinámica de la pala en el modelo de ruptura, se calculan los tiempos dimensionales de comienzo y finalización de la primera ruptura de estela y se extraen conclusiones.; With the objective of increasing knowledge regarding the behavior of Large-Scale Horizontal-Axis Wind Turbines (LSHAWTs) and provide a correct design for them, during the last years, the aerodynamic, aeroelastic and aeroservoelastic studies have become of interest. In this paper, a new numerical method to simulate the wake rupture against the supporting tower is developed. This simulation scheme is implemented into an existing computational code and represents an improvement in the process of detecting wake vortex segments going through the body of the tower. The numerical tool is based on a modified version of the well-known unsteady vortex-lattice method. In order to validate the efficiency and robustness of the proposed wake rupture method, current numerical results are compared against results obtained using a numerical scheme developed previously. Moreover, a qualitative analysis of shape variations of the wake rupture as a function of the number of aerodynamic elements on both the blades and the tower is carried out. Finally, to analyze quantitatively the influence of aerodynamic discretization of the blade on the wake rupture model, the starting- and ending-time of the first rupture are computed. Conclusions are drawn.

Genomic imbalances and microRNA transcriptional profiles in patients with mycosis fungoides Garaicoa, Fuad Huaman; Roisman, Alejandro; Arias, Mariana; Trila, Carla; Fridmanis, Miguel; Abeldaño, Alejandra; Vanzulli, Silvia; Narbaitz, Marina; Slavutsky, Irma Rosa Mycosis fungoides is the most common type of primary cutaneous T cell lymphoma. We have evaluated CDKN2A losses and MYC gains/amplifications by FISH analysis, as well as expression of miR-155 and members of the oncogenic cluster miR-17-92 (miR17, miR18a, miR19b, and miR92a) in MF patients with advanced disease. Formalin-fixed paraffin-embedded skin biopsies from 36 patients at diagnosis, 16 with tumoral MF (T-MF), 13 in histological transformation to a large T cell lymphoma (TR-MF), and 7 cases with folliculotropic variant (F-MF), were studied. Twenty cases showed genomic alterations (GAs): 8 (40 %) had CDKN2A deletion, 7 (35 %) showed MYC gain, and 5 (25 %) exhibited both alterations. GAs were more frequently observed in F-MF (p = 0.004) and TR-MF (p = 0.0001) than T-MF. GAs were significantly higher in cases presenting lesions in head, neck, and lower extremities compared to those observed in trunk and upper extremities (p = 0.03), when ≥25 % neoplastic cells were CD30 positive (p = 0.016) as well as in cases with higher Ki-67 proliferation index (p = 0.003). Patients with GAs showed bad response to treatment (p = 0.02) and short survival (p = 0.04). Furthermore, MF patients showed higher miRNA expression compared to controls (p ≤ 0.0223). T-MF showed higher miR17 and miR-18a expression compared to F-MF and TR-MF (p ≤ 0.0387) while miR19b, miR92a, and miR-155 showed increased levels in F-MF and TR-MF with respect to T-MF (p ≤ 0.0360). Increased expression of miR17 and miR19b in GA group compared to cases without alterations (p ≥ 0.0307) was also detected. Our results add new information about genomic imbalances in MF patients, particularly in F-MF, and extend the present view of miRNA deregulation in this disease.

Las elecciones en Estados Unidos desde América latina: ''racializando la agenda política'' latinos, trabajadores e indocumentados Artinian, Juan Pablo En este artículo queremos argumentar que el nuevo giro de “racialización” de la agenda política no debe verse simplemente como simple “demagogia” conservadora o progresista sino como un fenómeno sintomático de cambios más profundos producto de las tensiones económicas abiertas desde la crisis del 2008 y el legado del ciclo de guerras de inicios del siglo XXI que estarían configurando una cultura política que coloca en el centro de la escena tópicos como el racismo, la migración y la nueva configuración demográfica de los Estados Unidos. Algunos interrogantes que discutiremos en este artículo son: ¿Por qué la cultura política de los Estados Unidos está poniendo en el centro de la escena el debate en términos “racializados”? ¿Cómo podemos pensar este fenómeno más allá de nociones como “demagogia” o propaganda electoral? ¿Cómo podemos analizar –a partir de la perspectiva de Sudamérica- las tensiones y ansiedades que despierta esta retórica?

Evaluation of porosity change during chemo-mechanical compaction in flooding experiments on Liège outcrop chalk Wang, Wenxia; Madland, Merete V.; Zimmermann, Udo; Nermoen, Anders; Korsnes, Reidar I.; Bertolino, Silvana Raquel Alina; Hildebrand Habel, Tania The mechanical strength, porosity and permeability of chalk are affected by chemical and mineralogical changes induced by fluids that are chemically out of equilibrium with the host rock. Here, two high-porosity Upper Cretaceous chalk cores from Liège were tested at effective stresses beyond yield at 130°C during flooding with MgCl2 and NaCl brines. Core L1 (flooded by MgCl2 brine) deformed more than L2 (flooded with NaCl brine), with volumetric strains of 9.4% and 5.1%, respectively. The porosity losses estimated from strain measurements alone are 5.82% for L1 and 3.01% for L2. However, this approach does not account for dissolution and precipitation reactions. Porosity calculations that are based on strain measurements in combination with (i) the weight difference between saturated and dry cores and (ii) the solid density measurement before and after flooding show an average porosity reduction of 3.69% between the two methods for L1. This discrepancy was not observed for core L2 (with the NaCl brine). The rock and effluent chemistry show that Ca2+ dissolved and Mg2+ is retained within the core for the L1 experiment. Therefore, accurate porosity calculations in chalk cores that are flooded by non-equilibrium brines (e.g. MgCl2) require both the volumetric strain and chemical alteration to be considered.

Magnetic memory effect in magnetite charged polypropylene composite Mocellini, Ricardo Raúl; Lambri, Osvaldo Agustin F.; Gargicevich, Damian; Bonifacich, Federico Guillermo; Weidenfeller, Bernd; Anhalt, Mathias; Riehemann, Werner The behaviour of damping and dynamic shear modulus in polypropylene charged with either different volume fraction or size of magnetite (Fe3O4) particles, as a function of the applied magnetic field at 318, 353 and 403 K; has been studied. An increase of the alternating magnetic field oscillating with 50 Hz, leads to an increase of the damping. In addition, during the subsequently decreasing alternating magnetic field, the damping decreases, but a hysteretic behaviour appeared. The behaviour of the damping and the elastic modulus under the application of an alternating magnetic field was explained by the development of a magnetic fatigue damage occurring around the particle interface due to oscillation of magnetite particles. In contrast, during the increase of a direct magnetic field, the damping decreases and the elastic modulus increases. Measurements performed at 353 and 403 K allowed observing the interaction process among the particles of magnetite in the polymer matrix. After the decrease in the direct magnetic field, from the maximum reached value, damping and modulus remain smaller and higher, respectively; giving rise to a memory effect. In addition, a mesoscopic description of magnetite filled polymer composite materials has been performed in the continuous media by considering the interaction between magnetic and mechanical forces. Theoretical predictions of here developed model were qualitatively applied with good success for explaining the memory effect in magnetite filled polypropylene under the application of a direct magnetic field.

The Deregularization of Land Titles Galiani, Sebastián; Schargrodsky, Ernesto Santiago In the last years, several countries implemented policy interventions to entitle urban squatters, encouraged by the results of studies showing large welfare gains from entitlement. We study a natural experiment in the allocation of land titles to very poor families in a suburban area of Buenos Aires, Argentina. Although previous studies on this experiment have found important effects of titling on investment, household structure, educational achievement, and child health, in this article we document that a large fraction of households that went through a situation at which formalization was challenged (death, divorce, sale/purchase), ended up being de-regularized. The legal costs of remaining formal seem too high relative to the value of these parcels and the income of their inhabitants.

Espacios públicos practicados: entre el abandono y la recualificación. Rosario, 1990s. - tempranos 2000.1; Practiced public spaces: between abandonment and requalification. Rosario, 1990s. – early 2000 Godoy, Sebastián David El presente trabajo se pregunta acerca del potencial espacializante de las prácticas culturales en el contexto de las ciudades del capitalismo tardío y las transformaciones acaecidas en su espacio público. Desde hace más de veinte años, la ciudad contemporánea funcionó como el escenario de una serie de transformaciones asociadas el neoliberalismo, el capitalismo postindustrial, los dispositivos securitarios y la espectacularización de la vida, que se tradujeron en profundos problemas socioespaciales. En este contexto, el espacio público asumió una nueva relevancia en la medida que, desde las últimas décadas del siglo XX, constituyó una espacialidad disputada. Primero abandonado por el proceso de desindustrialización, fue luego el blanco de las acciones empresariales y estatales en materia de urbanismo y diseño. Frente a esto, en diversas ciudades comenzaron a proliferar intentos por parte de un abanico heterogéneo de agentes sociales por conseguir un acceso genuino a estos espacios, cada vez más despojados de su sentido público. Muchos de estos ensayos, adquirieron la forma de intervenciones estético-performáticas que buscaban mostrar que lo que hace público a un espacio era su apropiación colectiva. A continuación, se estudiarán algunas experiencias de usos artísticos y derivas estéticas que imprimieron nuevos sentidos a diversos espacios públicos de la ciudad de Rosario, entre mediados de la década de 1990 y comienzos del siglo XXI.; This paper wonders about the spatial potential of cultural practices in the context of the late capitalism cities and the transformations in their public space. For over twenty years, the contemporary city served as the setting for a series of transformations associated with neoliberalism, post-industrial capitalism, security devices and life as spectacle, which led to profound socio-spatial problems. In this context, urban public space assumed a new relevance to the extent that, since the last decades of the twentieth century it constituted a disputed spatiality. First abandoned by deindustrialization, it was then the target of state and enterprise actions in urban planning and design. Against this, in various cities began to proliferate a series of attempts by various social agents in order to achieve a genuine access to these areas, increasingly stripped of its public sense. Many of these attempts took the form of performative and aesthetic interventions that sought to show that what makes a public space was collective ownership. Coming up next, we will study some experiences of artistic uses and aesthetic drifts which printed new meanings to various public spaces in the city of Rosario, between the mid-1990s and early twenty-first century.
