Entre el archivo y el archivista: Reconstrucción y gestión del archivo sonoro de Carlos Vega; Between the archive and the archivist: Reconstruction and management of the sound archive of Carlos Vega Adduci Spina, Elina El archivo sonoro fundacional del Instituto Nacional de Musicología Carlos Vega (INM) fue generado por Carlos Vega como un objeto de estudio para examinar y clasificar las músicas populares de Argentina y Latinoamérica. Las investigaciones musicológicas de Vega se han convertido en un objeto de análisis en sí mismo. Sin embargo, ni Vega ni sus sucesores han puesto especial atención en la reflexión de la praxis de producción y clasificación documental. El presente artículo indaga la política documental desarrollada por Carlos Vega con el propósito de proponer una metodología posible para la gestión de su acervo. En primer lugar, se estudian los modos de creación, catalogación y selección iniciados por Vega y continuados por el instituto. En segundo lugar, se expone una serie de estrategias adoptadas en pos del abordaje integral y procesual del archivo sonoro institucional del INM.; The foundational sound archive of the Instituto Nacional de Musicología «Carlos Vega» (INM) was generated by Carlos Vega as an object of study to examine and classify the popular music of Argentina and Latin America. In turn, Vega’s musicological research has become an object of analysis in itself. However, neither Vega nor his successors have paid special attention to the reflection of the praxis of documentary production and classification. Therefore, this article investigates the documentary policy developed by Carlos Vega in order to propose a possible methodology for the management of his collection. First of all, the modes of creation, cataloguing and selection initiated by Vega and continued by the institute are studied. Secondly, a series of strategies adopted in pursuit of the integral and procedural approach of the institutional sound archive of the INM is exposed.

Photometric and numerical study of comet C/2021 A1 (Leonard) near its estimated disruption date Garcia, R. S.; Fernandez Lajus, Eduardo Eusebio; Di Sisto, Romina Paula; Gil Hutton, Ricardo Alfredo Initially on an elliptical orbit, C/2021 A1 experimented significant changes in its orbital configuration due to planetary perturbations upon entering the planetary region. Images of the comet C/2021 A1 (Leonard) obtained in March 2022 allow to estimate that its disintegration occurred in December 2021. The aim of this paper is to analyze the comet’s dust behavior during the period when its disintegration is presumed to have commenced, so a series of images of this comet on the broadband B, V, and R filters were taken on December 21 and 23, 2021 with the 0.6 m Helen Sawyer Hogg (HSH) telescope at the Complejo Astron´omico El Leoncito (CASLEO) to do a morphological, photometric, and numerical analysis of this comet. Analysis of the magnitudes and dust production rate suggests a significant increase in activity on December 21 compared to two days later, indicating a potential outburst. Digital filters were applied to enhance contrast in the cometary images, revealing two active regions on opposite sides of the nucleus. Additionally, the A(0◦) f ρ parameter was obtained for this comet. Finally, to gain deeper insights into Leonard’s dust behavior,observations were fitted to a newly developed theoretical model for studying dust comas. Combined with photometric data and gas production information from the literature, the analysis suggests that the comet’s activity on December 21, 2021, may mark the beginning of its disintegration.

Chronic NOD2 stimulation by MDP confers protection against parthanatos through M2b macrophage polarization in RAW264.7 cells Mansilla, Florencia Celeste; Miraglia, Maria Cruz; Maidana, Silvina Soledad; Randazzo, Cecilia Paola; Capozzo, Alejandra Victoria Innate immune cells show enhanced responsiveness to secondary challenges after an initial non-related stimulation (Trained Innate Immunity, TII). Acute NOD2 activation by Muramyl-Dipeptide (MDP) promotes TII inducing the secretion of pro-inflammatory mediators, while a sustained MDP-stimulation down-regulates the inflammatory response, restoring tolerance. Here we characterized in-vitro the response of murine macrophages to lipopolysaccharide (LPS) challenge under NOD2-chronic stimulation. RAW264.7 cells were trained with MDP (1 μg/ml, 48 h) and challenged with LPS (5 μg/ml, 24 h). Trained cells formed multinucleated giant cells with increased phagocytosis rates compared to untrained/challenged cells. They showed a reduced mitochondrial activity and a switch to aerobic glycolysis. TNF-α, ROS and NO were upregulated in both trained and untrained cultures (MDP+, MDP- cells, p > 0.05); while IL-10, IL-6 IL-12 and MHCII were upregulated only in trained cells after LPS challenge (MDP + LPS+, p < 0.05). A slight upregulation in the expression of B7.2 was also observed in this group, although differences were not statistically significant. MDP-training induced resistance to LPS challenge (p < 0.01). The relative expression of PARP-1 was downregulated after the LPS challenge, which may contribute to the regulatory milieu and to the innate memory mechanisms exhibited by MDP-trained cells. Our results demonstrate that a sustained MDP-training polarizes murine macrophages towards a M2b profile, inhibiting parthanatos. These results may impact on the development of strategies to immunomodulate processes in which inflammation should be controlled.

Mediante el análisis de cómo Han articula sus interpretaciones críticas de la analítica de Sein und Zeit, en el marco de sus propios planteamientos sociopolíticos contemporáneos, busco distinguir continuidades y diferencias entre ambas perspectivas. De esta manera me propongo poner en evidencia ambas comprensiones del existente humano articuladas en torno a los lazos sociales, para dar cuenta de sus alcances respectivos.; In the following paper we will distinguish the influence of Heidegger’s thought within the framework of Byung-Chul Han’s considerations of social and communal bonds, and their respective critical approaches to the metaphysical tradition of subjectivity. Analyzing the way Han articulates his critical interpretations of Sein und Zeit’s analytic within the framework of his own contemporary sociopolitical analyses, we will seek to distinguish continuities and differences between the two perspectives. In this way we intend to highlight both understandings of the human existent articulated around social ties, to account for their respective scopes.; No trabalho a seguir, distinguiremos a influência do pensamento de Heidegger nas elaborações de Byung Chul Han no quadro de suas considerações sobre os laços sociais e comunitários e de suas respectivas abordagens críticas à tradição metafísica da subjetividade. Partindo da análise da forma como Han articula suas interpretações críticas da analítica de Sein und Zeit, no quadro de suas próprias análises político-sociais contemporâneas, buscaremos distinguir continuidades e diferenças entre as duas perspectivas. Dessa forma, propomos destacar ambas as compreensões do ser humano existente articulado em torno dos laços sociais, para dar conta de seus respectivos alcances.

Datos de curvas de producción de CO2 y DO en fermentaciones con levaduras contaminantes de sidras de pera. Se informan los valores observados y los modelados junto con las curvas a lo largo del tiempo Se realizaron fermentaciones de mosto de pera en erlenmeyers de 50 ml, cada uno con 35 ml de mosto obtenido de un productor local, el cual fue esterilizado mediante filtración (0,22 μm). Estos se inocularon con levaduras contaminantes aisladas en el estudio, a saber, Zygosaccharomyces parabailii NPCC1791, Brettanomyces custersianus NPCC1813, o Brettanomyces bruxellensis NPCC1792, en una concentración final de 2 × 106 células/mL, por triplicado. Los matraces incubaron a 20 °C sin agitación durante 5 meses y se midieron densidad óptica (OD) y pérdida de peso (debido al CO2 liberado) hasta el final del ensayo. Los parámetros de crecimiento, incluido el crecimiento específico máximo, la velocidad (μ) y la duración de la fase de retraso (λ), se calcularon para ambos indicadores DO y CO2 utilizando una ecuación de Gompertz modificada propuesta por Zwietering et al. Los datos de crecimiento de cada tratamiento se ajustaron mediante un procedimiento de regresión no lineal que minimizó la suma de los cuadrados de la diferencia entre datos experimentales y el modelo ajustado, conocido como función de pérdida (observada - predicha). Este análisis fue realizado utilizando el módulo no lineal de Statistica 7.0 paquete de software con la opción Quasi-Newton (StatSoft,Tulsa, Oklahoma, EE. UU.)

Psychometric properties and Longitudinal Measurement Invariance of the Spanish version of the Alcohol Expectancies Questionnaire Short Form among young adult binge drinkers González Ponce, Bella M.; Pilatti, Angelina; Rivarola Montejano, Gabriela Belen; Bravo, Adrian J.; Fernández Calderón, Fermín Background: Longitudinal Measurement Invariance (LMI) is critically important to evaluate changes in alcohol expectancies over time. However, past research has not explored the longitudinal properties of the Spanish Expectancy Questionnaire Short Form (EQ-SF).Objectives: To examine the reliability, sources of validity (structural, invariance across sex, and concurrent validity), and LMI of the Spanish EQ-SF among young adults who engage in binge drinking.Methods: Participants (n = 279; 48.4% female) completed the EQ-SF and, two months later, completed it again along with measures of alcohol use, drinking motives, and protective behavioral strategies (PBS). We performed confirmatory factor analysis for structural validity and measurement invariance analysis for longitudinal and sex stability.Results: The eight-factor intercorrelated model (i.e. social facilitation, fun, sexual disinhibition, tension reduction, antisocial effects, negative emotional states, negative physical effects, and cognitive impairments) provided the best fit (χ2(df) = 497.29(224), CFI = .962, RMSEA = .064, SRMR = .049). This model was invariant across sex and time. Reliability coefficients (Ordinal alpha) for each dimension were consistently strong at both time points (from .72 to .93 at T1 and .73 to .91 at T2). Positive alcohol expectancies at baseline were positively related to alcohol use and drinking motives and negatively related to PBS at follow-up, demonstrating predictive validity.Conclusion: Our results support the temporal invariance of the EQ-SF scores among Spanish young adults who engage in binge drinking. The evidence supports the suitability of this measure for accurately assessing changes in alcohol expectancies over time in interventions aimed at preventing binge drinking in young adults.

Enjoyment in Sport and Alcohol Use among Adolescents: Examining the Mediating Role of Engagement Background: Alcohol consumption among young people is a significant public health concern. Previous studies have indicated that participation in sports, through the positive experiences it offers, may function as a protective factor for alcohol intake. This study aims to examine the influence of enjoyment and personal fulfillment on adolescent alcohol use, exploring the role of engagement with sports as a mediating variable. Method: A total of 370 adolescents (Mean age = 15.08; SD = 1.48) participated in the study and completed the Alcohol Use Disorder Identification Test, the Enjoyment in Sports Scale, and the Athlete Engagement Questionnaire. Results: The results demonstrated that enjoyment is related to lower alcohol consumption through personal fulfillment and engagement in the activity. Conclusions: It is crucial to facilitate positive experiences in sport that promote engagement and generate a sense of personal fulfillment, as these factors may reduce the likelihood of risky alcohol consumption.

Unforeseen plant phenotypic diversity in a dry and grazed world Gross, Nicolas; Maestre, Fernando T.; Liancourt, Pierre; Berdugo, Miguel; Martin, Raphaël; Gozalo, Beatriz; Ochoa, Victoria; Delgado Baquerizo, Manuel; Maire, Vincent; Saiz, Hugo; Soliveres, Santiago; Valencia Enríquez, Diego; Eldridge, David J.; Guirado, Emilio; Jabot, Franck; Asensio, Sergio; Gaitán, Juan José; García Gómez, Miguel; Martínez, Paloma; Martínez Valderrama, Jaime; Mendoza, Betty J.; Gonzalez, Sofia Laura; Oñatibia, Gastón Rafael; Peter, Guadalupe; Quiroga, Raul Emiliano; Yahdjian, María Laura; Zaady, Eli; Zeberio, Juan Manuel; Zhang, Yuanling; Zhou, Xiaobing; Le Bagousse Pinguet, Yoann Earth harbours an extraordinary plant phenotypic diversity1 that is at risk from ongoing global changes2,3. However, it remains unknown how increasing aridity and livestock grazing pressure—two major drivers of global change4–6—shape the trait covariation that underlies plant phenotypic diversity1,7. Here we assessed how covariation among 20 chemical and morphological traits responds to aridity and grazing pressure within global drylands. Our analysis involved 133,769 trait measurements spanning 1,347 observations of 301 perennial plant species surveyed across 326 plots from 6 continents. Crossing an aridity threshold of approximately 0.7 (close to the transition between semi-arid and arid zones) led to an unexpected 88% increase in trait diversity. This threshold appeared in the presence of grazers, and moved toward lower aridity levels with increasing grazing pressure. Moreover, 57% of observed trait diversity occurred only in the most arid and grazed drylands, highlighting the phenotypic uniqueness of these extreme environments. Our work indicates that drylands act as a global reservoir of plant phenotypic diversity and challenge the pervasive view that harsh environmental conditions reduce plant trait diversity8–10. They also highlight that many alternative strategies may enable plants to cope with increases in environmental stress induced by climate change and land-use intensification.

Quantum–Classical Hybrid Dynamics: Coupling Mechanisms and Diffusive Approximation Budini, Adrian Adolfo In this paper we demonstrate that any Markovian master equation defining a completely positive evolution for a quantum–classical hybrid state can always be written in terms of four basic coupling mechanisms. Each of them is characterized by a different “backaction” on each subsystem. On this basis, for each case, we find the conditions under which a diffusive limit is approached, that is, the time evolution can be approximated in terms of the first and second derivatives of the hybrid state with respect to a classical coordinate. In this limit, the restricted class of evolutions that guaranty the positivity of the hybrid state at all times (quantum Fokker-Planck master equations) emerges when the coupling mechanisms lead to infinitesimal (non-finite) changes in both the quantum and classical subsystems. A broader class of diffusive evolutions is obtained when positivity is only granted after a transient time or alternatively is granted after imposing an initial finite width on the state of the classical subsystem. A set of representative examples support these results.

MagMaR III—Resisting the Pressure, Is the Magnetic Field Overwhelmed in NGC6334I? Cortés, Paulo C.; Girart, Josep M.; Sanhueza, Patricio; Liu, Junhao; Martín, Sergio; Stephens, Ian; Beuther, Henrik; Koch, Patrick M.; Fernandez Lopez, Manuel; Sánchez Monge, Álvaro; Wang, Jia Wei; Morii, Kaho; Li, Shanghuo; Saha, Piyali; Zhang, Qizhou; Rebolledo, David; Zapata Gonzalez, Luis Alberto; Kang, Ji hyun; Jiao, Wenyu; Kim, Jongsoo; Cheng, Yu; Hwang, Jihye; Chung, Eun Jung; Choudhury, Spandan; Lyo, A. Ran; Olguin, Fernando We report on Atacama Large Millimeter/submillimeter Array observations of polarized dust emission at 1.2 mm from NGC6334I, a source known for its significant flux outbursts. Between five months, our data show no substantial change in total intensity and a modest 8% variation in linear polarization, suggesting a phase of stability or the conclusion of the outburst. The magnetic field, inferred from this polarized emission, displays a predominantly radial pattern from northwest to southeast with intricate disturbances across major cores, hinting at spiral structures. Energy analysis of CS (J = 5 → 4) emission yields an outflow energy of approximately 3.5 × 1045 erg, aligning with previous interferometric studies. Utilizing the Davis–Chandrasekhar–Fermi method, we determined magnetic field strengths ranging from 1 to 11 mG, averaging at 1.9 mG. This average increases to 4 ± 1 mG when incorporating Zeeman measurements. Comparative analyses using gravitational, thermal, and kinetic energy maps reveal that magnetic energy is significantly weaker, possibly explaining the observed field morphology. We also find that the energy in the outflows and the expanding cometary HII region is also larger than the magnetic energy, suggesting that protostellar feedback may be the dominant driver behind the injection of turbulence in NGC6334I at the scales sampled by our data. The gas in NGC6334I predominantly exhibits supersonic and trans-Alfvenic conditions, transitioning towards a super-Alfvenic regime, underscoring a diminished influence of the magnetic field with increasing gas density. These observations are in agreement with prior polarization studies at 220 GHz, enriching our understanding of the dynamic processes in high-mass star-forming regions.

Niobium oxide dispersed over PET waste activated carbon: an efficient catalyst for oxidation of the fungicide prothioconazole Oliveira, Cinthia C.; Gutierrez, Leandro Gabriel; Ferretti, Cristián Alejandro; Guedes Eid, Janaina; da Mota, Estella G.; Lana Gastelois, Pedro; Souza, Patterson P.; Bispo Oliveira, Jhonatan; Oliveira, Luiz C. A. Composite materials based on Nb2O5 nanoparticles dispersed over activated carbon (Nb/AC) obtained from PET waste were used as catalysts for wastewater treatment. These composites were synthesized by mechanical mixing of AC and commercial Nb2O5, followed by H2O2 treatment. The methylene blue dye (MB) was used as a model contaminant and the fungicide prothioconazole (PCZ) was the target molecule. Contaminant removal from water occurred mainly via adsorption by AC and via a combined process of adsorption/oxidation in the case of Nb/AC composites. The increase in the Nb amount in the catalysts reduced the BET surface area but increased the reaction rates due to the oxidation properties of Nb2O5. The reaction mechanism is Mars–Van Krevelen-like, driven by the peroxo groups (active sites) on the Nb2O5 surface. Moreover, the Nb/AC composites were highly efficient catalysts for PCZ oxidation and its main metabolite (prothioconazole-desthio) from water.

Retranslation as a means to reinvigorate a feminist agenda: the cases of Beya Durmiente (Dj Beya) and Desertoras Ferrero, Sabrina Solange; Placidi, Francesca This collaborative feminist and transnational study revises a selection of Gabriela Cabezón Cámara’s literary works. Expanding beyond literature, we focus on the theatrical realm, exploring how Cabezón Cámara’s feminist agenda in writing translates into stage adaptations. Centered on the novels Le viste la cara a Dios. La Bella Durmiente and Las aventuras de la China Iron, our analysis aligns with post-translation theories and examines Cabezón Cámara’s retranslation of the feminine subject(s), from narrations to performances. Adopting a framework that integrates multimodality, intermediality, and transdisciplinarity, we trace the construction of feminist subjectivities across various phases in the translation process, considering verbal and non-verbal elements.

Modificaciones epigéneticas en enfermedad de Alzheimer Campuzano, Karen Soledad; Galeano, Pablo; Morelli, Laura Los mecanismos epigenéticos son responsables de regular la expresión génica sin alterar la secuencia nucleotídica del ADN y se pueden ser modulados por factores ambientales. Existen varios mecanismos epigenéticos, entre ellos la metilación del ADN que ha sido ampliamente estudiada en enfermedades neurodegenerativas, como la enfermedad de Alzheimer (EA). Consiste en la adición de un grupo metilo en el carbono 5 de las citosinas formando la 5-metilcitosina (5mC), proceso catalizado por las ADN metiltransferasas (DNMTs). La 5mC se localiza principalmente en las regiones del genoma en las que existe una gran concentración de dinucleótidos citosina y guanina (CpG) y constituye un mecanismo de represión génica. En cerebros post-mortem de pacientes con EA se han observado alteraciones en los patrones de metilación que modifican la expresión de genes relacionados con diversos aspectos de la enfermedad. En 2009, se identificó la 5-hidroximetilcitosina (5hmC), que se forma por oxidación de la 5mC catalizada por las enzimas de translocación diez-once (TET1-3). La 5hmC ha demostrado ser una marca epigenética estable asociada a un incremento de la expresión génica y es particularmente abundante en el sistema nervioso central (SNC). Varios estudios apuntan a que la 5hmC cumpliría un rol importante en la EA. Los factores ambientales también contribuyen a la susceptibilidad y progresión de la EA. Una dieta saludable, la actividad física, la estimulación cognitiva y la interacción social, son algunos de los factores ambientales que se asocian a una mayor reserva cognitiva y a una disminución del riesgo de desarrollar la enfermedad. En contraste, el estrés crónico, la depresión, el aislamiento social, un nivel educativo bajo y los trastornos del sueño se han relacionado con un mayor riesgo de padecer EA. En modelos animales de EA, se ha reportado que la exposición a un ambiente con una mayor estimulación física y social (denominado ambiente enriquecido) mejora el desempeño en tareas que evalúan aprendizaje y memoria, aún sin disminuir la carga neuropatológica. Además, se ha reportado que tanto el ambiente enriquecido como el ejercicio físico modulan los patrones de metilación (5mC) e hidroximetilación (5hmC) en hipocampo. En resumen, los datos presentados ponen de manifiesto que las modificaciones epigenéticas 5mC/5hmC ejercen una influencia en el desarrollo de la EA y que las mismas pueden ser moduladas por factores ambientales, constituyendo posibles nuevos targets terapéuticos de intervenciones farmacológicas y no farmacológicas.

Fragility of Kardar-Parisi-Zhang universality class in the presence of temporally correlated noise Rodríguez Fernández, Enrique; Alés, Alejandro; Martín Álvarez, Jorge; López, Juan M. We study numerically a family of surface growth models that are known to be in the universality class of the Kardar-Parisi-Zhang equation when driven by uncorrelated noise. We find that, in the presence of noise with power-law temporal correlations with exponent θ, these models exhibit critical exponents that differ both quantitatively and qualitatively from model to model. The existence of a threshold value for θ below which the uncorrelated fixed point is dominant occurs for some models but not for others. In some models the dynamic exponent z(θ ) is a smooth decreasing function, while it has a maximum in other cases. Despite all models sharing the same symmetries, critical exponents turn out to be strongly model dependent. Our results clearly show the fragility of the universality class concept in the presence of long-range temporally correlated noise.
