Abstract. Comprehensive assessment of the long-term evolution of water stress and its driving factors is essential for designing effective water resource management strategies. However, the roles of water withdrawal and water availability components in determining water stress and potential mitigating measures in large water-scarce basins are poorly understood. Here, an integrated analytical framework was applied to the Yellow River basin (YRB), where the water crisis has been a core issue for sustainable development. The analysis suggests that the YRB has experienced unfavorable changes in critical water stress indicators over the past 56 years. Compared to the period from 1965 to 1980, the regional water stress index (WSI) and the frequency and duration of water scarcity increased by 76 %, 100 %, and 92 %, respectively, over the most recent 2 decades. Water withdrawal was the primary driver of the increased WSI before 2000; however, it has since contributed as much as water availability. Meanwhile, local water management and climate change adaptation were shown to be important in determining total water availability at the sub-basin scale. Water demand in the 2030s is predicted to be 6.5 % higher than during 2001–2020 (34.2 km3) based on the trajectory of historical irrigation water use and corrected socio-economic data under different Shared Socioeconomic Pathways (SSPs). To meet all sectoral water needs, a surface water deficit of 8.36 km3 is projected. Potential improvements in irrigation efficiency could address 25 % of this deficit, thereby alleviating the pressure on external water transfer projects. Such efficiency gains would enable the WSI of the YRB in the 2030s to be maintained at the current level (0.95), which would worsen conditions for 44.9 % of the total population while easing them for 10.7 % compared to in the 2000s. Our results have vital implications for water resource management in basins facing similar water crises to that in the YRB.
Technical note: A fast and reproducible autosampler for direct vapor equilibration isotope measurements

Published: January 2025

Abstract. To investigate water movement in environmental systems, stable isotope (2H and 18O) ratios of water are commonly used tracers. Analyzing the isotopic ratios of water in or adsorbed to substances like soil or plant tissue necessitates the extraction or equilibration of water prior to analysis. One such method, direct vapor equilibration, is popular due to its cost-effectiveness and straightforward sample processing. However, sample analysis requires significant manual labor, thereby limiting the number of samples that can be analyzed. This limitation is compounded by the fact that stored samples undergo evaporative isotopic changes over time. Moreover, manual measurements require many laborious procedural steps that can easily compromise reproducibility. The operator has to subjectively decide if the measurements are stable and then record the analyzer readings. To address these challenges, we have developed a system that automates the analysis process. Our autosampler for vapor samples, named VapAuSa, features a modular design that allows for up to 350 ports for direct vapor equilibration samples. These ports sequentially connect the prepared samples to a laser isotope analyzer, enabling continuous automated measurements. Within the accompanying software, measurement criteria can be specified, facilitating reproducible analysis. The developed system was tested by co-measuring 90 soil samples and 21 liquid water samples with known δ values. VapAuSa measurements have a negligible measurement bias (<1×10-13 ‰ for both δ2H and δ18O) and similar measurement repeatability compared to manual analysis of identical samples (δ2H=±4.5 ‰ and δ18O=±0.58 ‰ for VapAuSa measurements vs. δ2H=±5.7 ‰ and δ18O=±0.37 ‰ for manual analysis). However, the increased sample throughput minimizes storage-induced isotopic changes. Moreover, VapAuSa triples sample throughput per week while also reducing the direct labor time to just 10 % of that required for manual processing.

Abstract. Deep learning models have demonstrated remarkable success in fields such as language processing and computer vision, routinely employed for tasks like language translation, image classification, and anomaly detection. Recent advancements in ocean sciences, particularly in data assimilation (DA), suggest that machine learning can emulate dynamical models, replace traditional DA steps to expedite processes, or serve as hybrid surrogate models to enhance forecasts. However, these studies often rely on ocean models of intermediate complexity, which involve significant simplifications that present challenges when transitioning to full-scale operational ocean models. This work explores the application of convolutional neural networks (CNNs) in data assimilation within the context of the HYbrid Coordinate Ocean Model (HYCOM) in the Gulf of Mexico. The CNNs are trained to correct model errors from a 2-year, high-resolution (1/25°) HYCOM dataset, assimilated using the Tendral Statistical Interpolation System (T-SIS). The CNNs are trained to replicate the increments generated by the T-SIS data assimilation package, aiming to correct model forecasts of sea surface temperature (SST) and sea surface height (SSH). The inputs to the CNNs include real satellite observations of SST from the Group for High Resolution Sea Surface Temperature (GHRSST), along-track altimeter SSH observations (ADT), the model background state (previous forecast), and the innovations (differences between observations and background). We assess the performance of the CNNs across five controlled experiments, designed to provide insights into their application in environments governed by full primitive equations, real observations, and complex topographies. The experiments focus on evaluating (1) the architecture and complexity of the CNNs, (2) the type and quantity of observations, (3) the type and number of assimilated fields, (4) the impact of training window size, and (5) the influence of coastal boundaries. Our findings reveal significant correlations between the chosen training window size – a factor not commonly examined – and the CNNs' ability to assimilate observations effectively. We also establish a clear link between the CNNs' architecture and complexity and their overall performance. This research uses artificial intelligence to enhance ocean forecasting in the Gulf of Mexico. By using convolutional neural networks, the study improves predictions of sea temperatures and heights by integrating real satellite data with existing models. Through five comprehensive experiments, the team found that the amount of training data and the design of the neural networks significantly affect accuracy. These insights pave the way for faster, more reliable ocean models, benefiting environmental monitoring and maritime operations.
Imaginarios mesocráticos y relaciones campo-ciudad en la España contemporánea. Una lectura comparada de Las verdes praderas (1979) de José Luis Garci y Suro (2022) de Mikel Gurrea.
Authors: Zorita Arroyo Diego 
Published: January 2025

Este artículo analiza la evolución de las relaciones el campo y la ciudad en la España contemporánea, centrándose en el ascenso de la clase media y la degradación de las culturas rurales. A través del análisis comparativo de Las verdes praderas (1979) de José Luis Garci y Suro (2022) de Mikel Gurrea, se examina críticamente cómo los ideales mesocráticos, consolidados durante el desarrollismo franquista, han alimentado un anhelo por una Arcadia rural inexistente. Las verdes praderas muestra el desencanto de una clase media urbana emergente en los años 70, mientras que Suro aborda el retorno al campo desde las tensiones laborales, raciales y ecológicas del presente. El análisis contextualiza ambas obras en un marco histórico y ecológico que resalta las contradicciones del sueño mesocrático y su conexión con la actual crisis climática
“Quejío”: del pueblo para el pueblo. La construcción de lo popular como estrategia de difusión.
Authors: Pérez García Lucía 
Published: January 2025

Quejío, obra de teatro dirigida por Salvador Távora, representada por La Cuadra de Sevilla y asesorada por el escritor, director y crítico José Monleón, se estrenó en 1972. A partir tanto de los textos generados por el grupo y sus asesores --entrevistas, artículos y otras publicaciones--, como de aquellos producidos por parte de la crítica nacional e internacional --noticias, críticas, etc.--, se formula una cuidada imagen de la obra teatral que demuestra un gran interés por la identificación de la misma con lo "popular". En el presente artículo se indaga en este concepto como principal elemento de cohesión en la difusión de Quejío.
Construir lo pueblo. A partir de una constelación de seis arquitecturas menores: cueva, ermita, cosmos, barca, ruina y ensamblaje.
Authors: Velasco Sánchez Susana 
Published: January 2025

Esta contribución en forma de artículo y ensayo visual aborda la noción de lo pueblo desde el campo de la mediación arquitectónica. Se presenta una propuesta metodológica a través de la experiencia de seis espacios matrices que exploran dicha noción desde ángulos complementarios.
Esas seis morfologías son: cueva, ermita, concejo, barca, ruina y ensamblaje, y están fomuladas a partir de seis proyectos situados, realizados en comunidades y contextos concretos a lo largo de catorce años. La secuencia se presenta en un formato visual y dialógico desde las más primarias a las más elaboradas como seis estadíos de lo pueblo. Cada morfología lleva un subtítulo que aluden al proceso interno que en cada caso está teniendo lugar: lo animal, las imágenes, la alquimia, el imaginario, el cercamiento y el rencantamiento. Iniciándose la serie con el arraigo a la tierra y lo más animalesco, pasando pr la autorrepresentación que sucede al elaborar las imágenes propias y sus imaginarios, hasta llegar a momentos de desmoronamiento de lo comunitario, para concluir con la posibilidad siempre latente de hacer resurgir de las cenizas en una forma o contexto nuevo.
Como preámbulo al ensayo visual se elabora un marco de observación para esos seis proyectos que va decantando un método de trabajo, un guion de aproximaci´ón a eso que podríamos denominar «construir lo pueblo». En dicho marco se plantean a su vez tres aspectos de fondo que permiten deslindar algunas ideas con las que renovar la mirada sobre el hecho arquitectónico. Estos aspectos son: la sesibilización de la arquitectura como una zona medial, su capacidad de operar con las distintas escalas desde los cuerpos al pasaje, y por último su carácter de herramienta performativa para tejer vínculos tanto en lo común como en lo menor a través de prácticas que arraigan desde abajo.

Published: January 2025

This article presents the results of modeling of the temperature field of the experimental assembly of the VCG-135 test bench to study the interaction between model corium and candidate metal-coolers (zinc, antimony and manganese) in the conditions of a severe accident.The need for modeling is associated with the probability of metal melting in the discharge device due to the heat flow from the heating crucible of the experimental assembly. Thus, the purpose of the modeling was the justification of the integrity of the design of the metal discharge device during the production of liquid corium in the crucible of the experimental assembly.The thermophysical model was created in the ANSYS software. The temperature field of the experimental assembly was obtained at the moment of obtaining liquid corium as a result of the modeling. An analysis of the results showed that metal in the discharge device wouldn’t reach the melting point. In this regard, the discharge device of the experimental assembly can be used in its current design for experiments conducting at the VCG-135 test bench.At the same time, after the experiments, the thermophysical model was validated by comparing the calculated temperature values with experimental data. Validation of the model shows that the deviation of calculated and experimental temperature values at control points does not exceed acceptable limits (melting of the studied metal before interaction with corium). Thus, the developed thermophysical model can be used to justify further experiments on the VCG-135 test bench with the current experimental assembly.

We investigate the impact of the surface morphology on the contact properties of phosphorus doped poly-Si layers. If the poly-Si layer on a textured surface remains intact after high-temperature metallization using a fire-through (FT) silver (Ag) paste, the J0,metal is not expected to increase significantly while the specific contact resistivity can improve with a textured surface. The contact properties of the FT Ag contacts to n+ poly-Si deposited on both textured and planar surfaces are investigated by measuring and evaluating ρc and J0,metal. The reasons for differences in contact resistance and recombination are further investigated with SEM imaging. Solar cells with n-type polysilicon based passivating contacts on the rear side are fabricated and characterized. The scientific approach used, and the insights presented in this work, help to understand the mechanisms and behavior of screen-printed and fired-through contacts to polysilicon layers deposited onto textured silicon surfaces.

The project aims to bridge the communication gap between hearing individuals and the deaf community by developing a speech-to-sign language conversion system. This system transforms spoken language into corresponding sign language gestures, enabling real-time, inclusive communication. Leveraging advanced speech recognition algorithms and natural language processing (NLP), the spoken input is converted into text. The text is then analysed, segmented into meaningful components, and mapped to sign language gestures displayed as animations or visuals. This approach prioritizes accessibility and ease of use, ensuring that individuals with hearing impairments can participate seamlessly in conversations. The system's modular design allows adaptability for sign languages and continuous improvement through machine learning techniques. By combining cutting-edge technology with a user-centric focus, this project provides an innovative tool for enhancing inclusivity in communication.
