Abstract
To enhance isolation in gate-drive circuits for multilevel inverters, we proposed transversal piezoelectric boundary acoustic wave (PBAW) filters to replace previously used surface acoustic wave filters. First, we investigated transversal PBAW in a simple and easy-to-fabricate SiO2/Au/LiNbO3 structure. Calculations demonstrated that reducing the number of electrode pairs enhances propagation characteristics; however, this structure does not effectively mitigate signal degradation. Therefore, we investigated the SiO2/Ta2O5/Au/LiNbO3 structure, enabling better PBAW propagation. By optimizing with impedance matching, we achieved an insertion loss of less than 3 dB. To validate the feasibility of a transversal PBAW filter, we also experimentally investigated the SiO2/Au/LiNbO3 structured PBAW filter. Using substrate cut angles and processes available within our research group, we fabricated and evaluated the prototype, confirming PBAW propagation. These results suggest that transversal PBAW filters exhibiting excellent propagation characteristics using SiO2/Ta2O5/Au/LiNbO3 can be achieved with a precise Ta2O5 fabrication process. The study offers a viable solution for enhancing isolation performance in gate-drive circuits.

Stochastic decisions support optimal foraging of volatile environments, and are disrupted by anxiety
Authors: Lloyd Alex , McKay Ryan , Furl Nicholas 
Published: January 2025

AbstractAdolescence is a developmental period of relative volatility, where the individual experiences significant changes to their physical and social environment. The ability to adapt to the volatility of one’s surroundings is an important cognitive ability, particularly while foraging, a near-ubiquitous behaviour across the animal kingdom. As adolescents experience more volatility in their surroundings, we predicted that this age group would be more adept than adults at using exploration to adjust to volatility. We employed a foraging task with a well-validated computational model to characterise the mechanisms of exploration in volatile environments, preregistering the hypothesis that adolescents (aged 16–17; N = 91) would exhibit more optimal adaptation of their learning rate to changes in environmental volatility compared with adults (aged 24+; N = 90). However, surprisingly, both adolescents and adults exhibited suboptimal adjustment of their learning rate to environmental volatility. In contrast to the learning rate, it was instead participants’ stochasticity (i.e., decision variability) that better resembled the adjustment to volatility made by the optimal RL agent. Although heightened stochasticity in the volatile environment led participants to more often trial different responses that facilitated discovery of changes to the environment, we also found that anxiety impaired this adaptive ability. The finding of heightened stochasticity in volatile environments contradicts expectations that the learning rate is responsible for successful adaptation and motivates future work on the deleterious role that anxiety plays when adolescents manage periods of transition.

Abstract
The F10.7 index is crucial for assessing solar activity, significantly impacting communication, navigation, and satellite operations. The intrinsic complexity and variability of solar activity often result in sudden perturbations in the F10.7 index, compromising the accuracy and stability of forecasts. To address this challenge, we propose a novel prediction strategy that separately forecasts fundamental trends driven by the medium-to-long-term evolution of the solar cycle and the 27 day rotational modulation, along with transient disturbances caused by solar flares and the rapid evolution of active regions. These forecasts are then integrated to enhance overall prediction accuracy. We incorporate additional features such as the soft X-ray flare index (FISXR), magnetic type of the active region (new_Mag), and X-ray background flux (XBF) to enhance the understanding of the underlying physical processes of solar activity. Our experiments, conducted using advanced forecasting models on the SG-F10.7-All data set, validate the efficacy of our proposed strategy. Notably, the iTransformer model demonstrates superior performance in both short-term and medium-term forecasting scenarios. The inclusion of FISXR, new_Mag, and XBF significantly improves forecasting accuracy, highlighting their importance in improving the F10.7 index predictions. Our method outperforms international models from the Space Weather Prediction Center, British Geological Survey, and Collecte Localisation Satellites, exhibiting greater accuracy and adaptability across various solar activity phases. This finding provides a novel approach for precise forecasting of the F10.7 index.

Abstract
The radial gradient of gas-phase metallicity is a powerful probe of the chemical and structural evolution of star-forming galaxies, closely tied to disk formation and gas kinematics in the early Universe. We present spatially resolved chemical and dynamical properties for a sample of 25 galaxies at 0.5 ≲ z ≲ 1.7 from the MSA-3D survey. These innovative observations provide 3D spectroscopy of galaxies at a spatial resolution approaching JWST’s diffraction limit and a high spectral resolution of R ≃ 2700. The metallicity gradients measured in our galaxy sample range from −0.03 to 0.02 dex kpc−1. Most galaxies exhibit negative or flat radial gradients, indicating lower metallicity in the outskirts or uniform metallicity throughout the entire galaxy. We confirm a tight relationship between stellar mass and metallicity gradient at z ∼ 1 with small intrinsic scatter of 0.02 dex kpc−1. Our results indicate that metallicity gradients become increasingly negative as stellar mass increases, likely because the more massive galaxies tend to be more “disky.” This relationship is consistent with the predictions from cosmological hydrodynamic zoom-in simulations with strong stellar feedback. This work presents the effort to harness the multiplexing capability of the JWST NIRSpec microshutter assembly in slit-stepping mode to map the chemical and kinematic profiles of high-redshift galaxies in large samples and at high spatial and spectral resolution.
George Eliot en España durante el franquismo: religión, moral y censura
Authors: Riba Caterina , Sanmartí Carme 
Published: January 2025

George Eliot (1819-1880) escribió sus obras en un contexto protestante que se traslada a sus novelas, en las que aparecen tanto conflictos morales como pugnas entre confesiones religiosas y personajes que encarnan distintas profesiones. La visión del catolicismo que se proyecta en las novelas es muy crítica. Sin embargo, en época franquista se publicaron en el Estado español cuatro de sus novelas traducidas al castellano: Janet’s Repentance, Adam Bede, Silas Marner: the Weaver of Raveloe y The Mill on the Floss. Este estudio investiga por qué ni la censura administrativa ni los catálogos morales se ensañaron con Eliot. Para elucidar la cuestión se analizan los expedientes de censura, los catálogos morales y las modificaciones y manipulaciones del texto original en las distintas traducciones. Los expedientes de censura autorizaron la publicación de las diferentes ediciones sin tachaduras ni modificaciones y los catálogos no alertaron contra la inmoralidad de las novelas que nos ocupan. A la luz de los comentarios que aparecen tanto en los expedientes como en los catálogos, podemos afirmar que las obras de Eliot no se percibieron como una amenaza al régimen franquista ni al catolicismo, ya que estaban ambientadas en un país protestante, ajeno a la realidad española, sin traslación posible. La facilidad con la que las obras superaron este proceso se debe también a la autocensura previa llevada a cabo por los responsables de la traducción y la edición. Cuando llegaron a la censura, la mayoría de los fragmentos más críticos con el catolicismo ya habían sido expurgados.
Las residencias en el cine. Imaginarios y representaciones cinematográficas de la vida en residencias para personas mayores
Authors: Rey-Gayoso Raúl , Vivero-Saavedra Carlota 
Published: January 2025

El objetivo de este artículo es analizar la representación cinematográfica de las residencias para personas mayores. Recurrimos al método hermenéutico comparado para analizar cuatro películas de habla hispana estrenadas entre 2010 y 2020: Arrugas, El agente topo, La plaga y Quien a hierro mata. El análisis de resultados se fundamenta en un análisis temático inductivo, mediante la categorización e identificación de temas recurrentes en las tramas que analizamos desde planteamientos de la sociología y gerontología social. Argumentamos que la representación de las residencias en estas películas entraña, en diferentes grados, tendencias contrapuestas de reproducción y problematización de imaginarios estigmatizantes propios del nursing home specter. Por un lado, las narrativas privilegian la reproducción de un imaginario que asocia las residencias al abandono, la soledad y los malos cuidados, reforzando el ideal de cuidados familista que caracteriza a la sociedad española. Por otro, identificamos secuencias que evidencian la potencialidad del cine para problematizar estereotipos y profundizar en la comprensión de realidades complejas. Estos imaginarios cinematográficos cobran mayor relevancia en el actual contexto de replanteamiento del modelo residencial.

Published: January 2025

ABSTRACT
Climate change and the energy crisis are impeding global economic and sustainable development. As a high-carbon emissions industry, construction can practice green construction to reduce carbon emissions and mitigate global warming. Based on data from China's Beijing-Tianjin-Hebei region during the period 2010 to 2020, the spatiotemporal pattern and its influencing factors on the green development of construction were studied by using spatial econometric methods. The findings indicate that the level of green development of the construction industry in the region followed an alternating pattern of rising and falling but demonstrated a gradual overall upward trend during the period. The spatial distribution pattern shows that Beijing, Tianjin, and Shijiazhuang are the core cities, driving the development of surrounding smaller cities and that the influencing factors of green construction are technological innovation, industrial investment, urban greening level, labor force level, and urbanization level. This study provides scientific support and policy recommendations for narrowing the imbalance in the green development level of construction between regions in China and reducing carbon emissions generated by the construction industry.

Published: January 2025

ABSTRACT
With the expansion of public buildings in China and rise in carbon emission from energy consumption, it has become essential to improve the efficiency of public building operation energy consumption to reduce carbon emissions. However, it is not clear how to optimally reduce the energy consumption of public buildings from a holistic perspective. This study identifies the factors impacting energy consumption of public buildings by reviewing existing literature and establishes a framework for illustrating the interactions between the identified factors. The framework is validated through a case study of a university building in Beijing by methods of direct observation, instrument measurement, scrutiny of the building's operation records, simulating, and fitting. The framework demonstrates the interactions among the building energy consumption factors, which include social and economic factors, technology factors, building factors, environmental factors, occupant behavior patterns, and energy consumption equipment. The results of the study reveal the operation energy consumption of the case study university building regarding electricity consumption, energy utilization intensity, illumination of the building, and occupant behavior. It was found that indoor illumination intensities are affected by WWR, orientation of the room, and distance from the window, and that there is a functional relationship between illumination intensity and distance from the window. The outcomes of the study have significant contributions to the body of knowledge on energy consumption of public buildings. Theoretically, the proposed framework can help with understanding the relationships among the different factors affecting the energy consumption of public building operations. Practically, the measures arising from the study's empirical evidence, which include using a building automation system, installing solar panels with a potential to generate 31.6% of the building's total consumed energy, and improving occupants’ habits with impact of saving 18.8% of the total energy consumption of classrooms, can help optimize the operation of public buildings for improving energy consumption efficiency.
OCCUPANTS’ PERSONALIZED PREFERENCE FOR INDOOR THERMAL AND LIGHTING ENVIRONMENT OF OFFICE BUILDINGS: A CASE STUDY BASED UTILITY FUNCTION AND BAYESIAN INFERENCE
Authors: Longwei Qiu , Jian Yao 
Published: January 2025

ABSTRACT
Building thermal and lighting environment is a key concern in the construction industry. To study the personalized preferences of thermal and lighting environments, the indoor thermal and lighting environment in a typical office building in Ningbo was monitored and analyzed. Building users under different thermal and lighting environment conditions were asked to compare their satisfaction levels, and their environmental personalized preferences were identified and recorded along with the thermal and lighting environment parameters. The statistics show that the comfort zone for users is mostly between 16°C and 28°C. In addition, the usage of indoor lighting systems and the corresponding lighting environment parameters before and after usage were recorded. It can be observed that the average illumination value when using the lighting system is around 60 lux. When the indoor average illuminance reaches 430 lux, the users’ office requirements can be met without using the lighting system. Next, personalized learning of thermal and lighting environment comfort preferences was performed based on the experimental data. By combining Bayesian theory with utility function to define the likelihood function, a personalized learning model for thermal and lighting environment comfort personalized preferences was established. The joint distribution of thermal and lighting comfort environment was analyzed under the condition of thermal and lighting environment coupling. It is found that the observed comfortable lighting range for the occupants is from 300 lux to 6800 lux, and the range of thermal comfort is between corrected PMV (Predicted Mean Vote) values of –0.7 and 1.0.
La nature en guerre contre la vie. Une expérimentation d’écriture cyborg entre Guattari et Haraway

Published: January 2025

Cet article prend pour point de départ l’assertion de Guattari selon laquelle « [d]e tous les temps, la “nature” a été en guerre contre la vie » et tente de l’élucider à la lumière de la critique de la catégorie de nature dans le Manifeste cyborg de Haraway. Ainsi, la nature productrice de binarité fait face à la vie comme production cyborg non binaire, échappant à cette machine de normativisation, notamment par le biais d’écritures subversives permettant aux corps d’écrire leurs espaces. Ces mécanismes de subversion montrent dès lors que les questions de genre sont éminemment écologiques, appuyant le fait que les vivants sont les forces de réécriture de l’espace qui les conditionne au profit de milieux épais échappant à l’attracteur hors-sol de l’Anthropocène. L’article étant lui-même le fruit d’une expérimentation d’écriture collective, il espère esquisser dans sa forme même une telle écriture machinique/cyborg.
La fabrique des écoliers, ou l'enfance enfermée
Authors: Go Henri Louis 
Published: January 2025

Succédant aux tentatives asilaires du début du XIXe siècle, la forme scolaire telle qu'elle se matérialise dans l'appareil scolaire républicain à la fin du XIXe siècle a permis d'enrégimenter une partie de la population : l'enfance fut ainsi soumise à des geôliers praticiens d'une orthopédie sociale. Les promesses de la forme scolaire de socialisation et d'éducation de l'enfance s'avèrent être, dans sa construction historique, une tromperie. Le confinement scolaire est ainsi un bornage de l'être, une mise à sa place de l'élève. Le monde n'entre pas dans la classe qui reste désespérément vide. Que fait-on alors dans la salle de classe, si l'on ne doit y faire que ce que l'on fait ? Pour Hannah Arendt, l'institution scolaire est censée s'intercaler entre la famille et le monde pour faire transition car l'institution scolaire relève de la sphère prépolitique et l'on ne peut prétendre y forger, en agissant sur les nouveaux venus, un projet de transformation politique : les enfants ne peuvent ni ne doivent prendre part au monde. La forme scolaire classique est donc le premier acte d'une entreprise d'aliénation qui dépossède chacun de sa propre existence par des institutions d'enfermement. L'idée républicaine est liée à un modèle éducatif qui pense le gouvernement des enfants comme une fabrique de la passivité consentante et consensuelle. Ouverte en 1934 sur la colline du Pioulier à Vence, l'École Freinet est quant à elle un conservatoire pour l'enfance. Mais cette école n'est donc ni un espace clos « protégé des bruits extérieurs », ni un espace seulement intermédiaire où le monde n'entrerait que « représenté ». Elle constitue une alternative au mal-vivre qui pèse sur les écoliers.
SARS-CoV-2 Ct values and COVID-19 symptoms in patients with haematological malignancies in South Africa

Published: January 2025

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase polymerase chain reaction (RT-PCR) cycle threshold (Ct) values serve as surrogate markers for estimating viral load. Their usefulness in patients with haematological malignancies and COVID-19 has not been studied in the South African context.Objectives: To evaluate if a Ct value 30 can predict COVID-19 symptom development in adult patients with haematological malignancies.Method: A retrospective cohort study on adult patients with haematological malignancies and COVID-19 was conducted at Chris Hani Baragwanath Academic Hospital from 01 July 2020 to 31 July 2021. The relationship between Ct values, symptoms and disease severity, along with changes over time were evaluated.Results: Among 53 patients (50.9% male, median age of 38 years), Ct values 30 did not significantly predict COVID-19 symptom development (p = 0.417). However, severe disease correlated with lower Ct values (p = 0.002). No significant difference in the duration (days) from positive to negative tests was found between symptomatic and asymptomatic patients, and by severity of disease in the symptomatic patients. Lymphopenia was associated with severe disease, and those with lymphoid malignancies experienced longer viral shedding.Conclusion: Patients with haematological malignancies can exhibit symptoms at any Ct value but lower Ct values indicate more severe disease. This information can be critical for chemotherapy timing to minimize adverse outcomes.Contribution: The findings suggest a potential benefit in delaying chemotherapy at any Ct value as patients could present with acute SARS-CoV-2 infection at higher Ct values, and therefore face increased risk of adverse outcomes with early chemotherapy initiation.
