La construcción de las fronteras raciales de la sexualidad en el cine musical hollywoodense de los años treinta El caso de Jeni LeGon en Ali Baba Goes to Town (David Butler, 1937)
Authors: Aparisi Maria
Published: January 2024

El siguiente artículo pretende realizar un análisis de la representación cinematográfica de la negritud femenina en el cine musical hollywoodense de los años treinta a través de la figura de Jeni LeGon. Concretamente, tomaremos como objeto de estudio su interpretación dancística en «Swing Is Here To Sway» de la película musical Ali Baba Goes to Town (David Butler, 1937). En esta secuencia se combinan dos formas de representación de la negritud: aquella vehiculada por el blackface de su protagonista, de Aloysius «Al» Babson, interpretado por Eddie Cantor; y aquella que articulan los diferentes artistas afroamericanos que le acompañan, entre los cuales destaca la mencionada LeGon y las cantantes afroamericanas Peter Sisters. Nuestro trabajo prestará especial atención a la reflexividad resultante de la representación simultánea de estos dos significantes raciales, como una vía de acceso a las implicaciones más profundas, los miedos y deseos, que caracterizan la entrada de la diferencia racial y sexual, dancística y musical, en el terreno cinematográfico hollywoodense.
Un evangelio queer: los mundos místicos de Febrônio Índio do Brasil
Authors: Rothbard Jesse
Published: January 2024

El 31 de agosto de 1927, la policía de Rio de Janeiro detuvo a un sospechoso que creía era responsable por el asesinato de dos menores en las afueras de la ciudad. El individuo detenido y luego encarcelado por los crímenes era Febrônio Índio do Brasil, un hombre de raza mixta de unas de las comarcas más marginales de Minas Gerais y que era, presuntamente, homosexual. La cobertura periodística del caso estableció a Febrônio como uno de los asesinos en serie más infames de la historia brasileña, un legado que conserva hasta hoy en día. Un elemento fundamental de la sensacionalización del caso era la misteriosa conexión entre los asesinatos y un texto místico que Febrônio publicó el año antes bajo el título, As Revelações do Principe do Fogo. Tildado como un libro incomprensible, los positivistas brasileños usaron las Revelações como evidencia de la locura de Febrônio y, además, para caracterizar la homosexualidad como una enfermedad mental. Este ensayo presenta una lectura contextual de As Revelações para demostrar la posibilidad de interpretar el libro como una reacción subalterna a los cambios de las geografías raciales y urbanas de Rio en los años veinte. En una ciudad transformada por una noción de la modernidad en la que cuerpos negros y queer no tenían lugar, Febrônio creó un mundo místico donde tales cuerpos podían seguir existiendo. Su libro es una reformulación radical del libro de Apocalipsis que revela los horizontes queer de un mundo por venir a través de la disolución de la trinidad sagrada y la articulación de una intimidad erótica que une al mesiánico Príncipe de Fuego con lo Divino. Así, As Revelações representa la creación textual de un mundo místico queer.

Published: January 2024

Hacer cine es un oficio hecho de muchos gestos y oficios pequeños. Acompañar a las películas a lo largo de su vida también es un pequeño oficio compuesto de muchos oficios. Como homenaje a la huella que dejó en nuestras vidas Jean-Luc Godard, presentamos un acompañamiento o dos, uno o dos de tantos acompañamientos posibles, a Histoire(s) du cinéma, que fue a su vez una de las muchas formas con las que Godard acompañó y se dejó acompañar por el cine.
La enseñanza de las oraciones concesivas del español a los aprendices brasileños: un estudio basado en las Tareas Formales y la Instrucción de Procesamiento para la didáctica de las lenguas cercanas
Authors: Perez de Obanos Romero Gregorio
Published: January 2024

El estudio experimental aplica la Instrucción de Procesamiento y las Tareas Formales para la enseñanza a estudiantes brasileños de la selección modal en las oraciones concesivas con la conjunción aunque. Para ello, se compararon los dos tipos de instrucción, además del grupo de control, en un diseño con pretest y dos postest: el primero contenía también actividades de inferencia contrastiva y de práctica de la traducción directa e inversa. Los resultados muestran que el grupo de tareas formales presenta, en general, mayores índices de respuestas correctas independientemente del modo verbal (indicativo o subjuntivo), del tipo de evaluación y del tiempo entre la prueba inmediata y la aplazada. Estos hallazgos son consistentes con trabajos precedentes.
Aportaciones de la lingüística cognitiva al ámbito de ELE: la enseñanza-aprendizaje de las metáforas lingüísticas
Authors: Ureña Tormo Clara Ureña
Published: January 2024

En los últimos años han aumentado las contribuciones de la lingüística cognitiva al ámbito de la enseñanza de lenguas segundas y extranjeras (L2/LE) en general y al ámbito del español como lengua extranjera (ELE) en particular. En ese marco, este artículo pretende ofrecer una visión general sobre los principios teóricos de la lingüística cognitiva destacando las implicaciones más relevantes para la didáctica de la lengua. Asimismo, el trabajo pone el foco en la enseñanza-aprendizaje de las metáforas, considerado un aspecto esencial en la adquisición de una LE/L2 desde la óptica cognitivista. Tras desarrollarse conceptos clave como la competencia metafórica y la conciencia metafórica, se establecen unas orientaciones didácticas para la práctica docente y se concluye con la necesidad de trasladar al aula los avances obtenidos en las investigaciones realizadas.
Uso de tiempos de pasado por alumnos rifeños de Español como Lengua Extranjera
Authors: ERRAHMOUNI YASSIN
Published: January 2024

El nivel de competencia lingüística de los estudiantes rifeños¹ en español puede afectar a su capacidad para producir textos escritos precisos y coherentes. Esto sucede especialmente en el nivel B1, donde se espera que los estudiantes sean capaces de expresarse de forma clara y efectiva en español, tanto en términos de gramática como de vocabulario, de modo que puedan desenvolverse lingüísticamente de forma adecuada en distintos contextos.
Las insuficiencias que presentan los aprendices rifeños a la hora de utilizar los tiempos de pasado en español se podrían clasificar en confusiones dentro del paradigma verbal del pasado (tanto entre el pretérito perfecto y el indefinido, como entre el indefinido y el imperfecto), así como otras confusiones vocálicas y errores de acentuación, entre otras.
En este estudio, se presenta un estudio de caso y se propone una metodología efectiva para la corrección de estos errores gramaticales con el fin de que sirvan de ayuda para superar estas dificultades y mejorar su capacidad para producir textos escritos de manera coherente.
La enseñanza del registro coloquial a través de nuevos géneros: la tertulia deportiva en el aula de E/LE
Authors: Salameh Jiménez Shima
Published: January 2024

El uso de recursos basados en registro y género en la enseñanza de E/LE constituye una práctica habitual, tanto con materiales de ficción, como series y películas, como con conversaciones coloquiales genuinas pertenecientes a diferentes corpus. La tertulia, por su parte, es un género que combina, cada vez más, rasgos propios de la conversación coloquial (sin ser una muestra prototípica de inmediatez completa en términos de Koch y Oesterreicher, 2007, o de prototipicidad, según Briz, 2010), con un escenario interactivo distinto que permite, en el campo de la enseñanza, aislar mejor determinados fenómenos pragmáticos para su estudio. El presente artículo propone una secuencia centrada en la tertulia deportiva, por su carácter actual y atractivo para determinados grupos de edad, así como por su acceso libre desde diferentes medios de cara a la preparación de materiales. El foco lingüístico recae sobre dos tipos de estrategias verbalizadoras: las fórmulas de tratamiento y los marcadores discursivos.
La financiarización y la dominación de la política monetaria en México durante la pandemia
Authors: Duarte Rivera César
Published: January 2024

El artículo analiza los efectos de la financiarización sobre la política económica en México. El proceso de financiarización y liberalización financiera trajo aparejado una serie de modificaciones estructurales en la implementación de la política económica. Así se entró en un momento de dominación de la política monetaria, donde el papel de la política fiscal ha sido relegado y se ha encargado a los bancos centrales la conducción de la intervención estatal en la economía. Por su parte la política monetaria en este contexto tiene dos características principales, la estrategia de metas de inflación y la priorización del objetivo de estabilidad del nivel de precios. En economías como la mexicana, se ha hecho eco de la modificación en las estrategias de política económica con la particularidad de que el tipo de cambio se ha convertido en un objetivo implícito de política. Ello se explica por la fuerte dependencia de la economía mexicana respecto al exterior y las posibles consecuencias que una crisis de depreciación cambiaria causada por una salida masiva de capitales pudiera tener sobre la economía. Esto también limita la capacidad de actuación del Banco de México, al tener que considerar los acontecimientos internacionales para definir su actuación. La reacción de las autoridades mexicanas durante la pandemia mostró claramente la operación de este esquema de dominación subordinada de política monetaria, el cual fue altamente inefectivo al ser incapaz de impactar sobre el financiamiento bancario a través de las facilidades de liquidez, lo que trajó como consecuencia la caída en la actividad económica más profunda desde la Gran Depresión.

Authors: Colombini Iderley
Published: January 2024

El objetivo de este artículo es realizar un análisis crítico del conflicto de clases en Brasil en el contexto de la crisis social reciente, pero no para proponer una revisión de las disputas, sino para enfatizar cómo las luchas y contradicciones se dan en el propio proceso de constitución de las nuevas formas de clase en el capitalismo brasileño. De ahí la necesidad de comprender la lógica de la constitución de clases en Brasil y las nuevas disputas con las nuevas formas de financiarización y constitución del individuo capitalista.
Presentación
Authors: Vidal Gregorio
Published: January 2024

El mapa de América Latina está compuesto por un importante número de países con gobiernos que se reivindican como progresistas o de izquierda. Al inicio del año 2023 las cinco mayores economías de la región contaban con este tipo gobiernos. En varios de estos países era un resultado reciente, después de un largo periodo en que predominó la agenda del Consenso Washington. Por ejemplo, en México la ejecución de una política económica y una estrategia de transformación de la economía y de la sociedad con base en las recomendaciones del FMI y el Banco Mundial, llevando a cabo las denominadas reformas estructurales inicia desde finales de los años ochenta del siglo pasado y se mantiene hasta el final del gobierno de Enrique Peña Nieto, en diciembre de 2018. En el camino existieron diversas crisis bancarias, del mercado de valores y del mercado de cambios, recesiones de diverso alcance, mantenimiento de una notable desigualdad social y un débil crecimiento de la economía. En Colombia, la continuidad no se afectó ni siquiera por la permanencia de los conflictos político-militares y el mantenimiento de organizaciones armadas. Ello implica, como se destaca en el texto intitulado Los gobiernos progresistas y la política económica en América Latina, que es parte de este número de la revista, un cambio relevante en el curso de los años recientes.
La mirada de conjunto, con algunos énfasis en las dos mayores economías de la región, que dan contenido al presente número de la revista considera el espacio de la política económica como resultado de la acción de grupos y sectores sociales que actúan en el terreno mismo del Estado. Se destaca que al interior de cada uno de los Estados de la región se realizan luchas y se impulsan diversos proyectos, que pueden incluso plantear serias diferencias entre instituciones estatales de relevancia como los gobiernos y los bancos centrales. En las condiciones actuales, se observan en toda la región notables restricciones a la actividad económica producto del encarecimiento del crédito y el mantenimiento de la restricción externa en materia de financiamiento. Además, para unos cuantos existen resultados positivos producto de la colocación de recursos en múltiples espacios financieros. Impulsar un proyecto que considere la ampliación de la inversión resulta particularmente difícil. Concitar las condiciones para que diversos grupos sociales se empeñen en la modificación del proceso de formación de capital con la perspectiva de ampliar las capacidades de producción con base en el incremento y predominio del empleo formal no resulta tarea sencilla. En política económica no es posible la preponderancia de lo monetario, menos si se postula como tarea prioritaria el control de la inflación. La clave es la creación de condiciones para el aumento de las capacidades de producción, que necesariamente consideran un conjunto de fuerzas sociales que lo impulsan.
Special issue introduction
Authors: Ngô Tâm T. T. , Wagner Sarah
Published: January 2024

This special issue examines Asian experiences of war and mass death in the
previous century, with case studies from China, Japan, Korea and Vietnam (North
and South, among its diaspora and across multiple generations). In this
introduction we highlight several of the wider analytical interventions offered
by the articles: (1) the spatiopolitical dynamics of war dead
accounting in which forms of vernacular forensic expertise interact with and
inform internationally honed, empirically grounded practices of exhumation and
identification; (2) the complex hierarchy of authority over
remains that structures programmes of war dead accounting; (3) the
variegated (as opposed to monolithic) nature of war dead
themselves; and (4) the material ecosystems of remains, graves,
cemeteries and the non-human forces of decay acting upon them.
Finally, the introduction highlights the issue’s comparative potential:
that is, what these different cultural, religious and ideological modes of
meaning-making reveal about why and how human remains matter in the aftermath of
war – and not just according to Western notions of national memory
politics in which the soldier stands in for the state and collective mourning
animates the national imaginary.

Topic models with elements of neural networks: investigation of stability, coherence, and determining the optimal number of topics
Authors: Koltcov Sergei , Surkov Anton , Filippov Vladimir , Ignatenko Vera
Published: January 2024

Topic modeling is a widely used instrument for the analysis of large text collections. In the last few years, neural topic models and models with word embeddings have been proposed to increase the quality of topic solutions. However, these models were not extensively tested in terms of stability and interpretability. Moreover, the question of selecting the number of topics (a model parameter) remains a challenging task. We aim to partially fill this gap by testing four well-known and available to a wide range of users topic models such as the embedded topic model (ETM), Gaussian Softmax distribution model (GSM), Wasserstein autoencoders with Dirichlet prior (W-LDA), and Wasserstein autoencoders with Gaussian Mixture prior (WTM-GMM). We demonstrate that W-LDA, WTM-GMM, and GSM possess poor stability that complicates their application in practice. ETM model with additionally trained embeddings demonstrates high coherence and rather good stability for large datasets, but the question of the number of topics remains unsolved for this model. We also propose a new topic model based on granulated sampling with word embeddings (GLDAW), demonstrating the highest stability and good coherence compared to other considered models. Moreover, the optimal number of topics in a dataset can be determined for this model.
Evaluating environmental DNA detection of a rare fish in turbid water using field and experimental approaches

Published: January 2024

Detection sensitivity of aquatic species using environmental DNA (eDNA) generally decreases in turbid water but is poorly characterized. In this study, eDNA detection targeted delta smelt (Hypomesus transpacificus), a critically endangered estuarine fish associated with turbid water. eDNA sampling in the field was first paired with a trawl survey. Species-specific detection using a Taqman qPCR assay showed concordance between the methods, but a weak eDNA signal. Informed by the results of field sampling, an experiment was designed to assess how turbidity and filtration methods influence detection of a rare target. Water from non-turbid (5 NTU) and turbid (50 NTU) estuarine sites was spiked with small volumes (0.5 and 1 mL) of water from a delta smelt tank to generate low eDNA concentrations. Samples were filtered using four filter types: cartridge filters (pore size 0.45 μm) and 47 mm filters (glass fiber, pore size 1.6 μm and polycarbonate, pore sizes 5 and 10 μm). Prefiltration was also tested as an addition to the filtration protocol for turbid water samples. eDNA copy numbers were analyzed using a censored data method for qPCR data. The assay limits and lack of PCR inhibition indicated an optimized assay. Glass fiber filters yielded the highest detection rates and eDNA copies in non-turbid and turbid water. Prefiltration improved detection in turbid water only when used with cartridge and polycarbonate filters. Statistical analysis identified turbidity as a significant effect on detection probability and eDNA copies detected; filter type and an interaction between filter type and prefilter were significant effects on eDNA copies detected, suggesting that particulate-filter interactions can affect detection sensitivity. Pilot experiments and transparent criteria for positive detection could improve eDNA surveys of rare species in turbid environments.

A comparative study between buckling behaviour and statistical analysis of axially loaded fully encased composite columns made with high strength concrete
Authors: P SASIKUMAR
Published: January 2024

This research presents a buckling behaviour of axially loaded fully encased composite columns made with high strength concrete (HSC). Additionally, the research includes experimental study, numerical analysis, and statistical analysis. Three fully encased composite columns (FECC) cast with different cross sections are 200mm x 200mm, 230mm x 200mm, 250mm x 200mm, and 2800mm, respectively. The FECC specimens were made with 80MPa grade of concrete and ISMB 100 x 50 x 7 x 4.2 steel section, including the experimental, analytical, and numerical analyses. The buckling resistance of FECC specimen results were compared to Euro code – 1994 and American Institute of Steel of Construction 360 – 2010 codes. Finite element analysis (FEM) studied the FECC specimens and predicted the buckling resistance compared to the experimental test results. The FEM analysis closely correlated to the experimental results. The statistical analysis was performed on the FECC specimens with current design codes and previous experimental research work. The statistical study compared the experimental test results of buckling resistance and flexural stiffness of FECC specimens to the predicted values from codes. The numerical and statistical analysis results were compared to the experimental test results. Also, it is highly correlated and helps the performance of columns.
Optimization of fiber-reinforced deep cement-fly ash mixing column materials
Authors: EKMEN Arda Burak , ALGIN Halil Murat
Published: January 2024

The flexural and compressive strength requirements of deep cement mixing (DCM) columns subjected to lateral loading have brought forth the demand to specify how the incorporation of fiber and fly ash improves these properties and the mixture quality, including the construction design characteristics of segregation and swelling. The paper addresses this issue considering the experimental results from the extensive parametric study in which various lengths and content of carbon fiber (4-, 6-, and 12-mm lengths and 0.1, 0.4, 0.8% by volume of the mixture) are incorporated into the cement-based mixtures with and without the optimized fly ash content. Along the strength parameters, the effects of mixture quality responses on the performance of DCM columns are also investigated. The segregation results of the fresh mixtures, unconfined compression strength (UCS), flexural strength, and swelling values from the 28-day cured specimens are presented. The novel version of the Goal Attainment Method is used for the optimizations, in which the procedures of high-order regression equations and the multi-objective desirability contents are included to obtain more accurate optimization results in terms of the controlling parameters of segregation, swelling, UCS, and flexural strength. The setting time and workability results from the mixtures having the optimized parameters are also presented to demonstrate the fluidity of the optimized mixtures. The addition of carbon fiber led to significant improvements in the segregation and swelling ratios, with gains of up to 35%. Moreover, the three-point flexural strength and unconfined compressive strength were enhanced by 278% and 54%, respectively. The paper specifically reveals that the incorporation of carbon fiber significantly improves the mixture quality characteristics of segregation and swelling as well as the parameters of flexural strength and UCS.

Published: January 2024

Este artigo aborda as campanhas de vacinação destinadas aos idosos no Brasil, especificamente contra o vírus da Influenza H1N1. Além disso, busca analisar os aspectos relacionados à educação em saúde durante essas campanhas, bem como aborda o fenômeno da histerese. Através de uma revisão integrativa, qualitativa e descritiva, pretende-se avaliar a atenção dedicada ao tema ao longo de um período de 30 anos, examinando se as publicações refletem adequadamente a amplitude da questão, especialmente no que diz respeito às contra campanhas promovidas por propagandas negativas relacionadas às vacinas. Os resultados da revisão indicam uma quantidade ínfima de artigos relacionados ao tema, destacando a necessidade premente de ampliar os estudos científicos nessa área. Isso se torna crucial para que a discussão sobre a vacinação de idosos não se restrinja apenas a matérias veiculadas em sites da internet, carecendo de uma abordagem mais robusta e embasada academicamente. Em conclusão, urge a importância de promover pesquisas mais aprofundadas e abrangentes sobre a temática, a fim de enriquecer o debate e subsidiar intervenções mais eficazes no âmbito da saúde pública.

Published: January 2024

As the smallest unit in national development, villages must be independent and reduce financial dependence from the central and regional governments. Financial independence can be achieved by optimizing the role of village-owned enterprises (BUMDesa). One of the roles of BUMDesa Srimartani is the management of the Kembangsari Traditional Market. This study aims to analyze: 1) merchant and consumer satisfaction, 2) determinants of consumer satisfaction, and 3) the influence of consumer satisfaction on the local economy, using Importance-Performance Analysis, consumer satisfaction index, and Partial Least Square. The results showed that the level of satisfaction with market management was included in the satisfied category. Factors that influence the level of consumer satisfaction are accessibility, product condition, and physical infrastructure. The responsibility factor does not significantly affect customer satisfaction. Local economy can be considerably influenced by consumer satisfaction. Increased consumer satisfaction causes the market to develop faster and increases the acceptance of market levies. As a result, the local economy will grow through an increase in the original local revenue.

Authors: Manu F. , Usman U. , Audu A. , Isah B. Y.
Published: January 2024

In this paper, a three parameter model called Zubair- Kumaraswamy (Z-Kum) distribution is proposed. The extension was done using Zubair G-Family [1] of continuous probability distribution to extend the well knownKumaraswamy distribution to make it more flexible in modeling and predicting real world phenomenon.  Some basic structural properties of the new distributions like cdf, pdf, quantile functions, moments, moment generating functions, characteristics functions and order statistics was obtained. Survival function, hazard function, reversed hazard rate function and a cumulative hazard rate function was also obtained. Behavior of the hazard rate plot exhibit increase, decrease, Bathtub and inverted Bathtub shape. Maximum likelihood estimate was used to estimate the Z-Kum distribution parameters. Monte Carlo simulation was carried out to evaluate the performance of MLE method adopted. Result of the simulation studies indicates that MLE is good for the estimation of our distribution parameters. To compare the proposed model with the other fitted existing models, analytical measure of goodness of fit of some information criterion was considered using three real life data sets. From the results obtained, it is evident that our proposed model gives better fit than the other competing models and therefore, our proposed model provide greater flexibility in modeling real world phenomenon.

Published: January 2024

Activated Carbon of high adsorption efficiency and highly active surface properties were prepared from water melon fruits peels by using 1M H2SO4 solution, followed by activation at 300oC for 30 minutes. The adsorption capacity of the activated carbon is considered on the following; the effect of concentration, adsorbent dosage, and contact time. The physicochemical characteristics such as ash content (18.7%), pH(6.72),moisture content (1.82), bulk density(0.36) and conductivity (32.4) were investigated to understand the adsorptive capacity of activated carbon prepared from water melon peels. The adsorptive efficiency of the adsorbent in removing Cadmium and Copper ions from wastewater were compared with Langmuir and Freundlich adsorption isotherm, which proved effective removal efficiency within the range of 91.80 – 99.98 %. On the whole chemically activated watermelon peels should be used in treating our wastewaters, for a cleaner and healthier environment.

Analysis of variance for the design of experiment revealed highly significant difference for all the characters which expressed huge amount of diversity among 20 genotypes of wheat. Phenotypic coefficients of variation (PCV) were higher than genotypic coefficients of variation (GCV) for all the characters. The maximum GCV and PCV were observed for ear length (cm) (26.37 & 27.04) followed by number of productive tillers per plant (23.72 & 25.65) and test weight (21.76 & 22.57 g). The maximum value of heritability was shown by number of spikelets per ear (98.05), number of seed per spike (97.59), ear length (95.12cm), test weight (92.99 g), biological yield per plant (91.99 g), plant height (89.86 cm), seed yield per plant (87.28 g), days to maturity (86.67) and number of productive tillers per plant (85.56). The highest genetic advance was found for number of productive tillers per plant (45.20), number of seed per spike (43.60), test weight (43.24 g), seed yield per plant (37.37 g), no of ears par plant (34.99) and number of spikelets per ear (31.49). High heritability coupled with high genetic advance for the characters number of productive tillers per plant, no of ears per plant, ear length, number of spikelets per ear, number of seed per spike, test weight and seed yield per plant which indicated that above characters were governed by additive gene action and direct selection may be useful for further improvement program.

Studies on the synthesis of some sulfa quinoxaline has generate a considerable reputation as a result of their outstanding biochemical properties. This recent study was designed to prepared some sulfa quinoxaline hydrazone derivatives and studying their antimicrobial potency. The 3-methyl-2-oxo-1,2-dihydroquinoxaline-6-sulfonohydrazone derivatives were synthesized by the reactions of 3-methyl-2-oxo-1,2-dihydroquinoxaline-6-sulfonohydrazide and six substituted benzaldehydes and examined for their possible antibacterial potency. The synthetic compounds exhibited wide-ranging spectrum action counter to twenty-four bacteria strains with minimum inhibitory concentrations values 0.0313 - 0. 250 mg/mL.  This is a suggestion that such compounds could be used to formulate antibiotics to circumvent the problem of increasing resistance by pathogens to the existing synthetic antibiotics.

Photosynthetically active radiation (PAR; 0.4 - 0.7μm) is a key driver in ecosystem biochemical processes, and thus a critical factor in agriculture productivity, ecosystem-atmosphere energy, and CO2 fluxes. In this study, the measured monthly averaged daily global solar radiation, relative humidity, wind speed, minimum and maximum temperature dataset was utilized to estimate and investigate the Photosynthetically Active Radiation (PAR) for Ikeja (latitude 6.58 N, longitude 3.33 E and 39.4 m above sea level) located in the coastal region ofNigeria. The meteorological parameters used in this work were obtained from the archives of National Aeronautics and space Administration (NASA) for a period of thirty-eight years (1984-2021).The newly developed temperature PAR based models were statistically tested using the coefficient of determination (R2), Mean Bias Error (MBE), Root Mean Square Error (RMSE), Mean Percentage Error (MPE), t – test and index of Agreement (IA) to ascertain the accuracy and applicability of the models. The results show that, the highest and lowest values of PAR were found during the rainy season with 8.3426 MJ  and 6.4936 MJ  in the months of April and July respectively. Based on the developed models, the model equation (16g) is the most suitable for estimating PAR for Ikeja with R2, MBE, RMSE, MPE, t-test and IA values of 80.9 , 0.0062 MJ , 0.3415 MJ  -0.1974  0.0601 and 92.8712  respectively.

Immunomodulatory biomaterials are increasingly used in regenerative medicine. Biomimetic glycopeptide hydrogel is found to accelerate cutaneous wound healing by inducing macrophage M2‐type polarization, however, it is unclear whether this will possibly orchestrate a pro‐regenerative T cell immunity. Here the aim of this study is to elucidate the reparative T‐cell immune response in tissue regeneration by augmenting macrophage‐T cell crosstalk with a novel immunomodulatory glycopeptide hydrogel (termed as GRKgel) self‐assembled by mannose receptor‐binding glucomannan (GM) chemically grafted with RADA16‐conjugated T‐cell epitope. The glycopeptide can be phagocytized and processed by macrophages, which then presents peptides to naïve T cells and polarizes them into T helper 2 (TH2) cells through IL‐4‐dependent STAT6/GATA3 or c‐Maf pathways. Strikingly, full‐thickness skin wound repair in mice indicates a superior efficacy of GRKgel on restoring the pathological structure and hair follicle by provoking TH2 immune response, increasing the residence of M2 macrophages, as well as promoting angiogenesis at the local tissue environment. Furthermore, genomics results illustrates the role of GRKgel serving as an immunomodulatory niche, orchestrating immune cell crosstalk and promoting extracellular matrix (ECM) reconstruction. Collectively, this study highlights the significance of crosstalk between immune cells in evoking pro‐healing T‐cell immunity, providing a promising drug‐/cytokine‐free strategy for endogenous tissue regeneration.
Unravelling Size‐Dependent and Coupled Properties in Mechanical Metamaterials: A Couple‐Stress Theory Perspective

Published: January 2024

The lack of material characteristic length scale prevents classical continuum theory (CCT) from recognizing size effect. Additionally, the even‐order material property tensors associated with CCT only characterize the materials' centrosymmetric behavior and overlook their intrinsic chirality and polarity. Moreover, CCT is not reducible to 2D and 1D space without adding couples and higher‐order deformation gradients. Despite several generalized continuum theories proposed over the past century to overcome the limitations of CCT, the broad application of these theories in the field of mechanical metamaterials has encountered significant challenges. These obstacles primarily arise from a limited understanding of the material coefficients associated with these theories, impeding their widespread adoption. Implementing a bottom‐up approach based on augmented asymptotic homogenization, a consistent and self‐sufficient effective couple‐stress theory for materials with microstructures in 3D, 2D, and 1D spaces is presented. Utilizing the developed models, material properties associated with axial‐twist, shear‐bending, bending‐twist, and double curvature bending couplings in mechanical metamaterials are characterized. The accuracy of these homogenized models is investigated by comparing them with the detailed finite element models and experiments performed on 3D‐printed samples. The proposed models provide a benchmark for the rational design, classification, and manufacturing of mechanical metamaterials with programmable coupled deformation modes.

Quasi‐solid zinc‐ion batteries using hydrogel electrolytes show great potential in energy storage devices owing to their intrinsic safety, fewer side reactions and wide electrochemical windows. However, the dendrite issues on the zinc anodes cannot be fundamentally eliminated and the intrinsic anode‐electrolyte interfacial interspace is rarely investigated. Here, we design a dynamically healable gelatin‐based hydrogel electrolyte with a highly reversible sol‐gel transition, which can construct a conformal electrode‐electrolyte interface and further evolve into a stable solid‐solid interface by in situ solidification. The unique helical gelatin chain structure provides a uniform channel for zinc ion transport by the bridging effect of sulfate groups. As a consequence, the dynamically healable interface enables dendrite‐free zinc anodes and repeatedly repairs the anode‐electrolyte interfacial interspaces by the reversible sol‐gel transition of gelatin electrolyte to retain long‐lasting protection for sustainable zinc‐ion batteries.

Improving the selectivity of electrochemical CO2 reduction to multi‐carbon products (C2+) is an important and highly challenging topic. In this work, we propose and validate an effective strategy to improve C2+ selectivity on Cu electrodes, by introducing a synergistic effect between cation (Na+) and aprotic solvent (DMSO) to the electrolyte. Based on constant potential ab initio molecular dynamics simulations, we first revealed that Na+ facilitates C−C coupling while inhibits CH3OH/CH4 products via reducing the water network connectivity near the electrode. Furthermore, the water network connectivity was further decreased by introducing an aprotic solvent DMSO, leading to suppression of both C1 production and hydrogen evolution reaction with minimal effect on *OCCO* hydrogenation. The synergistic effect enhancing C2 selectivity was also experimentally verified through electrochemical measurements. The results showed that the Faradaic efficiency of C2 increases from 9.3 % to 57 % at 50 mA/cm2 under a mixed electrolyte of NaHCO3 and DMSO compared to a pure NaHCO3, which can significantly enhance the selectivity of the C2 product. Therefore, our discovery provides an effective electrolyte‐based strategy for tuning CO2RR selectivity through modulating the microenvironment at the electrode‐electrolyte interface.
