Erotismo y cotidianidad femeninos: Representación y desmitificación en Bestiario doméstico de Brianda Domecq
Authors: Obregón Julio Romano
Published: September 2024

En Bestiario doméstico (1982), Brianda Domecq retrata, satiriza y desmitifica múltiples aspectos de la vida de la mujer en los ámbitos doméstico, sexual y social. Las opresiones que históricamente han definido la condición de la mujer, señaladas y criticadas por Mary Wollstonecraft ya en el siglo xviii, y que han sido ejercidas desde la posición de dominación masculina, encuentran en la obra de Domecq una crítica que pretende subvertir estereotipos y fantasías construidos desde la visión masculina de lo social, que reduce el papel de la mujer al ámbito doméstico, en sentido funcional, cuando no a lo meramente decorativo.
Female Erotism and Everyday Life: Representation and Demystification in Brianda Domecq’s Bestiario Doméstico
Abstract
In Bestiario doméstico (1982), Brianda Domecq portrays, satirizes and demystifies women’s daily life in domestic, sexual and social fields. Oppressions that have defined the role of women in society, perpetuated mainly by male dominance, have been observed and criticized since 18th Century by Mary Wollstonecraft. These oppressions and this dominance find in Brianda Domecq’s fiction a portrait but also a critic that pulls to subvert stereotypes as well as fantasies built from a male vision of how society should work, a vision that reduces women’s role to a domestic function, when not limited to the decorative.

Borderlands. La Frontera. The New Mestiza: una frontera situada en el símbolo mítico de Aztlán
Authors: Pérez Joselyn
Published: September 2024

El objetivo de este proyecto es revisar y estudiar el concepto de frontera en la obra de la escritora chicana Gloria Anzaldúa: Borderlands. La Frontera. The New Mestiza. En este sentido, el primer paso es un análisis general acotado únicamente al estudio geográfico de la franja fronteriza con México-u.s.a. En esta parte, se explora la conceptualización de un tercer país y sus implicaciones, para después, en un segundo momento de estudio, comprender el proceso de mitificación de este territorio, por lo que se intenta dar una breve comprensión sobre cómo se configuran los espacios míticos, para finalmente, recuperar el mito de Aztlán y sus evocaciones al texto chicano.
Borderlands. La Frontera. The New Mestiza: a Frontier Located in the Mythical Symbol of Aztlán
The objective of this research project is to review and study the concept of the border in the work of the Chicana writer Gloria Anzaldúa: Borderlands. La Frontera. The New Mestiza. In this sense, the first step is a general analysis limited only to the geographical study of the border strip with Mexico- u.s.a. In this part we explore the conceptualization of a third country and its implications, and then in a second part of the study we try to understand the process of mythification of this territory, so we can give a brief understanding of how mythical spaces are configured, so we might finally recover the myth of Aztlán and its evocations to the Chicano text.

La epistemología ch’ixi en el estudio de la oralitura. Una introducción
Authors: López Espinosa Raúl Homero
Published: September 2024

La tensión entre oralidad y escritura indígenas es básica para entender la literatura latinoamericana. Algunas expresiones de esta tensión son oralitura, etnotexto y etnoliteratura. El objetivo es problematizar estos conceptos a partir de la idea de subalternidad y evidenciar cómo, frente a las pocas teorías y metodologías que los estudian, la epistemología ch’ixi de Silvia Rivera Cusicanqui es pertinente. Se muestra que la comprensión de aquella tensión puede entrañar un colonialismo. Finalmente, el artículo sugiere que desde lo ch’ixi es posible una lectura autónoma e interdisciplinaria de dichas expresiones, congruente con su carácter.
Ch’ixi epistemology in the study of oraliture. An introduction
Abstract
The tension between indigenous orality and writing is fundamental to understanding Latin American literature. Some expressions of this tension are oraliture, ethnotext, and ethnoliterature. The aim of this article is to problematize these concepts based on the idea of subalternity and to show how, in the face of the few theories and methodologies that study them, the ch’ixi epistemology of Silvia Rivera Cusicanqui is pertinent. It is shown that the understanding of this tension can entail colonialism. Finally, it is suggested that from the ch’ixi perspective, an autonomous and interdisciplinary reading of these expressions, consistent with their nature, is possible.

Tres médicos escritores
Authors: Torres Vicente Francisco
Published: September 2024

Este artículo borda sobre tres médicos mexicanos que han combinado su profesión con la escritura literaria: E. Césarman, B. Estañol y F. Ortiz Quezada. El asunto no es nuevo, si recordamos la nómina que incluye a Chejov y Céline, pero una visión unitaria sobre tres mexicanos resulta pertinente, no sólo porque son contemporáneos, sino porque Estañol y Césarman llegaron a escribir libros al alimón. La mirada humanista de su ejercicio médico es un común denominador, que tienen porque siempre piensan en el afán comercial que se ha ido apropiando de su noble tarea. Otro es la inquietud que muestran por desentrañar qué materia hay en la mente de los escritores que los hace diferentes del resto de los mortales. Aunque no llegan a una conclusión válida, seguir sus búsquedas en una aventura fascinante e iluminadora.
Three Medical Writers
 Abstract
This article discusses three Mexican doctors who have combined their profession with literary writing: E. Césarman, B. Estañol and F. Ortiz Quezada. The issue is not new if we remember the list that includes Chekhov and Céline, but a unitary vision of three Mexicans is pertinent, not only because they are contemporaries but also because Estañol and César came to write books together. The humanistic view of their medical practice is a common denominator they have because they always think of the commercial zeal that has been appropriating their noble task. Another is the concern they show to unravel what matter is in the minds of writers that makes them different from the rest of mortals. Although they do not come to a valid conclusion, continue their searches in a fascinating and enlightening adventure.

Enfermedad y estilo en Huysmans: desintegraciónde la figura del soltero en À Rebours
Authors: Videla Martínez Julieta
Published: September 2024

In the 19th century, the figure of the “bachelor” (artist) appeared as a gesture of resistance to the advance and generalisation of bourgeois and utilitarian life, which was imposed in an excessive manner. J.K. Huysmans’ À Rebours is the narration of a spirit jaded by thisimposition. Chapter six of the novel recreates the figure of the bachelor in des Esseintes as a way of life, during his past, which, because of neurosis, is exacerbated in a desire for solitude and isolation until it reveals a process of gradual disintegration of the character. I argue that, because of its stylistic composition, this novel triggers, towards the end of the 19th century, a declining process of disintegration of the nineteenth-century figure ofthe bachelor and creates a new figure, that of the  "alone”, which is why I will concentrate our aesthetic-hermeneutic reading on the chapter mentioned above.

Countering Urban Redundancy with a Multipronged Strategy: Lessons from Ashram Road, Ahmedabad
Authors: Acharya Mohik
Published: September 2024

Urban redundancy, often observed in the core areas of cities, poses significant challenges to sustainable development and urban vitality. This study addresses urban redundancy by proposing a quantitative framework to both identify and mitigate its effects, using Ashram Road in Ahmedabad, India, as a case study. The research employs a Multi-Criteria Decision-Making Analysis (MCDMA) based on data collected through physical surveys and literature reviews. This analysis integrates approaches such as redevelopment, adaptive reuse, policy interventions, and economic strategies to counter redundancy effectively. The findings highlight that Ashram Road's core area, despite its historical and cultural significance, faces challenges like poor maintenance, high vacancy rates, and inadequate utilization of the available floor space index (FSI). The proposed framework aims to develop context-sensitive strategies that uphold the intrinsic value of core urban areas while promoting sustainable regeneration. The study demonstrates the need for a balanced approach that combines modern development with preservation, providing insights for urban policy-making that enhances the resilience and longevity of city cores.
The Morphological Impact of Restructuring Routes: Atatürk Boulevard's Palimpsest Phenomenon
Authors: Bozdoğan Güllü , Gürer Tan Kamil
Published: September 2024

Restructuring routes are significant urban elements that lead to physical changes in cities to meet modern needs, often resulting in traumatic transformations. This study investigates the morphological impact of the palimpsest phenomenon on Istanbul's Atatürk Boulevard, an exemplar of restructuring routes. The Boulevard's construction disrupted the organic urban fabric, creating a new structure and altering the area's identity. By employing a typomorphological analysis based on Conzen’s Town Plan Analysis, this research examines changes in the street, building, and subdivision systems. The study utilizes historical and contemporary maps to reveal the effects of Atatürk Boulevard on urban morphology, demonstrating both positive and negative consequences of restructuring routes. Findings indicate that the boulevard increased the economic value of the area but also led to the fragmentation and loss of historical urban elements, contributing to a complex urban palimpsest. The study highlights the need for sensitive urban planning to preserve the city's historical identity while accommodating modern developments. The insights gained are crucial for architects and urban planners in managing urban landscapes, ensuring sustainability, and respecting historical contexts in future developments
Comparative Spatio-Temporal Dynamics of Urban Sprawl in Algerian Cities Skikda and Tébessa (1985-2024) Using GIS and Landsat Imagery
Authors: Lbtissem Lounis , Lamia Leulmi , Lazhar Gherzouli , Youcef Lazri
Published: September 2024

This study analyzes urban sprawl in the Algerian cities of Skikda and Tébessa from 1985 to 2024, utilizing supervised classification of Landsat satellite imagery and GIS analysis. Skikda, a coastal city, experienced a 68% increase in built-up areas due to industrial growth and coastal geography, whereas Tébessa, an inland city, saw a 45% increase, with growth moderated by its topography and economic structure. The findings illustrate how socio-economic factors, land-use policies, and geographical characteristics influence urban expansion patterns. Skikda's rapid, scattered growth contrasts with Tébessa's controlled expansion. This study highlights the need for customized urban planning strategies that consider local contexts to manage urban sprawl effectively. By comparing the dynamics of coastal and inland cities, the research provides valuable insights for sustainable urban development in medium-sized Algerian cities, offering a framework for similar studies nationwide.
Socio-Economic Impact of the Mass Rapid Transit (MRT) System in Dhaka: A Case Study of Mirpur Stations
Authors: Raj Shahriar Iqbal , Mohino Inmaculada , Khatun Farjana
Published: September 2024

Mass Rapid Transport (MRT) has become pivotal in sustainable urban transportation, especially in densely populated cities like Dhaka, the capital of Bangladesh. Dhaka is implementing its first MRT system, which includes 17 stations, with three located in Mirpur. Mirpur, a significant area due to its diverse economic activity and population, is an important case study for understanding the effects of the MRT system. The study area spans 58.66 square kilometers and has a population of 632,664, representing a zone with unplanned mixed uses and a spontaneously developed favorable job-housing ratio conducive to transit-oriented development (TOD). Challenges such as last-mile connectivity and capacity limitations could impede the MRT's socio-economic potential. Moreover, the current land use and urban planning framework are not adequately prepared to support future TOD. This research highlights the necessity of proactive legislative changes and infrastructural improvements to optimize the success of Mirpur's MRT stations. Despite being in service for only a year and facing a lack of real-life data, this study focuses on Mirpur MRT stations to explore the socio-economic impacts of MRT systems, aiming to enhance knowledge in urban transportation and development.
Developing an Objective Visual Quality Evaluation Pipeline for 3D Woodblock Character
Authors: Thuong Le Cong , Nam Le Viet , Duyen Ngo Thi , Jung Seung-won , Ha Le Thanh
Published: September 2024

Vietnamese feudal dynasty woodblocks are invaluable national treasures, but many have been lost or damaged due to wars and poor conditions of preservative environments. Fortunately, 2D-printed papers of the damaged or lost woodblocks have been well-preserved, allowing for reconstruction their 3D digital version. To ensure accurate reconstruction of 3D woodblocks, it is essential to have a reliable alignment method that closely matches human visual perception. In this paper, we introduce an automatic pipeline for objective visual quality evaluation of woodblock characters. The pipeline includes two components: the first shifts the quality evaluation from 3D domain to 2D domain by employing orthogonal projection to transform a 3D mesh woodblock character model into a 2D depth map image with minimum information loss. The second utilizes established 2D perceptual metrics, which closely align with human visual perception, to evaluate the 2D depth map. Our evaluation demonstrates that features of these proposed perceptual metrics employed in the pipeline can effectively characterize the visual appearance of the woodblock character based on our prepared dataset. Additionally, the experiments presented in the paper also demonstrate that these metrics can sensitively detect degradation levels in both the foreground and background components of a woodblock character.

Published: September 2024

Opinion mining holds numerous practical applications, especially as user-generated sentiment data become increasingly prevalent in the digital age. Comparative Opinion Mining (ComOM), a specific sub-field of opinion mining, focuses on extracting the elements involved in the comparison in a text and retrieving the corresponding tuples expressing comparative opinions. This research describes an improved version of our system that participated in the VLSP 2023 ComOM shared task. The baseline system’s performance was ranked second among 22 participating systems in the shared task through a combination of generative model and classification-based approaches, along with knowledge-based techniques with a 0.2300 F1-score. More experiments have been conducted to improve the performance of the system, reaching a final F1-macro score of 0.2391. This demonstrates the superiority of our proposed method compared to existing approaches in the task of comparative opinion mining.

Published: September 2024

We report the adaptive laboratory evolution (ALE) of Clostridium ljungdahlii (Cl) for enhanced syngas fermentation, enabling its integration into a photocatalytic CO₂-to-syngas conversion system for the upcycling of CO₂ to C₂ products, acetate and ethanol. The adapted strain, Cladapt, exhibits a 2.5-fold increase in growth rate and a 120-fold enhancement in C₂ production compared to the wild-type (Clwt). Isotopic labeling confirmed Cladapt's high conversion efficiency, yielding 6:1 and 9:1 ratios of ¹³C:¹²C in acetate and ethanol, respectively. Whole genome sequencing revealed eight unique mutations in Cladapt, whereas RNA-seq identified significant alterations in gene expression, shedding light on its enhanced metabolism. Coupling Cladapt with a CO₂-to-syngas converting semiconductor-molecule hybrid photocatalyst, TiO₂|phosphonated Co(terpyridine)₂, enabled the assembly of a photocatalytic domino system for CO2-to-syngas-to-C2 conversion. This study offers a streamlined approach to improving syngas fermentation in Cl, insights into microbial adaptability, and an ALE-guided pathway for solar-powered CO₂ upcycling using an inorganic-bacterial cascade strategy.

Solid-state batteries (SSBs) with silicon anodes could enable improved safety and energy density compared to lithium-ion batteries. However, degradation arising from the massive volumetric changes of silicon anodes during cycling are not well understood in solid-state systems. Here, we use operando X-ray computed microtomography to reveal micro-to-macro-scale chemo-mechanical degradation processes of silicon anodes in SSBs. Mud-type channel cracks driven by biaxial tensile stress form across the electrode during delithiation. We also find detrimental cracks at the silicon/solid electrolyte interface that form due to local reaction competition between neighboring domains of different sizes. Continuum phase-field damage modeling quantifies stress-driven channel cracking and shows that the lithiated silicon stress state is critical for determining the extent of interfacial fracture. This work reveals novel mechanisms that govern SSBs compared to conventional lithium-ion batteries and provides guidelines for engineering chemo-mechanically resilient electrodes for high-energy batteries.
Plasmonic microgel actuation induced by diffractively excited modes

Published: September 2024

Light-driven soft actuators at the microscale have gained significant interest owing to their flexible and contactless manipulation of small objects. However, a major challenge in this field is the limited number of control parameters for deformation, resulting in relatively simple actuation modes. To achieve complex deformable actuators, it is crucial to increase the number of control parameters. We investigated the deformation of PNIPAM microgels induced by diffractively excited plasmons, chosen for their high controllability. Upon irradiation with 830-nm light, the microgel rapidly shrank by 53% in width, followed by a return to its original state. The photothermal conversion efficiency using Au gratings was estimated to be 88 times higher than that of non-plasmonic Au thin films. This enhanced deformation was tunable by controlling not only the polarization angle of the excitation light but also the grating area. The deformation of the grating with an area of 30 um^2 was four times greater than that with an area of 15 um^2, despite the entire irradiated spot being confined within each grating area due to the superposition of the plasmonic waves.

Cu is the most promising metal catalyst for CO2 electroreduction (CO2RR) to multi-carbon products, but the structure sensitivity of the reaction and the stability versus restructuring of the catalyst surface under reaction conditions are still controversial. Here, atomic scale simulations of surface energies and reaction pathway kinetics supported by experimental evidence unveil that CO2RR does not take place on perfect planar Cu(111) and Cu(100) surfaces but rather on steps or kinks defects, and that these planar surfaces tend to restructure in reaction conditions to the active stepped surfaces. By combining basin hopping global sampling and grand canonical density functional theory, we show that the extremely low CO coverage on (111) and (100) surfaces, originating from sluggish CO2 conversion and unfavorable CO binding, limits the ability of these surfaces to reduce CO2 to multi-carbon products. Steps and kinks at surfaces, despite the lack of decrease in C-C coupling barriers on these sites, exhibit a significant increase in activity arising from beneficial CO2 activation and higher CO coverage. Notably, the square motifs adjacent to defects, not the defects themselves, are the active sites for CO2RR via synergistic effect. In addition, the strong binding of CO on defective sites acts as a thermodynamic driving force for the restructuring of planar surfaces to active stepped terminations under reactive conditions. We evaluate these mechanisms against experiments of CO2RR on UHV-prepared ultraclean Cu surfaces. Overall, our findings highlight the structural sensitivity in steering CO2RR and elucidate the origin of in situ restructuring of Cu catalysts during the reaction. We furthermore feature that the active sites for CO2RR are created under reaction conditions.

Published: September 2024

In this paper, the structure and properties of interpolymer complexes (IPC) based on sodium carboxymethylcellulose with a linear carbopol were studied. Interpolymer complexes were obtained by mixing aqueous solutions of Na-CMC and carbopol components in various ratios of components and pH of the medium. The structure of the obtained products was determined using the methods of IR spectroscopy and X–ray diffraction analysis. IR spectra in the range of 400-4000 cm-1 were recorded on spectrophotometers "NIKOLET Magna-560 IR" and "Specord–75 IR" (Karl Zeiss, GDR). X-ray diffraction analysis of IPС films was carried out on a Rigaku X-Ray installation with an X-ray generator with a rotating copper anode, at a voltage of 40 kV, with a current strength of 15 mA and using characteristic Cu-Ka radiation in the area of angles 0 <2θ <40. IR spectroscopic data show that the interpolymer complexes based on Na-CMC and carbopol obtained in moderately acidic regions are stabilized due to the cooperative hydrogen bond between the carboxyl groups of Na-CMC and the carbonyl groups of carbopol. X-ray diffraction analysis has shown that a change in the composition of the interpolymer complex leads to a change in the structure, which depends on the structure and nature of the interchain bonds. It is ascertained that an increase in the number of hydrogen bonds leads to a more ordered state of the resulting interpolymer complex. It is revealed that the formation of an interpolymer complex due to hydrogen bonds provides additional stability. This can serve as one of the means of controlling the structure and properties of the IPC of sodium carboxymethylcellulose with carbopol.

Tras casi dos décadas de avances, en el 2020 se instaló el programa GRD como mecanismo de pago para los hospitales públicos desde el FONASA. Sin embargo, la pandemia de COVID-19 enlenteció su desarrollo. En el 2022 se retomó la aplicación y, tras evaluar el programa, se evidenció que los conglomerados de hospitales predefinidos para el pago diferenciado por GRD no lograron diferenciar grupos homogéneos. En el 2023 se reformó el programa y se aumentaron los recursos financieros, se definió un solo conglomerado y una tasa base, y se reconoció una mayor complejidad hospitalaria que la de años previos. Además, se agregaron tres hospitales al programa, con un total de 68.

Conclusiones.

La experiencia muestra que es posible dar continuidad a una política pública de financiamiento de la salud para lograr una mayor eficiencia y equidad en el sistema de salud, sobre la base de la existencia de instituciones robustas que persistan en su desarrollo y mejoramiento continuo.
