Published: October 2024

This study provides a thorough examination of power losses and total harmonic distortion (THD) in single-phase 9-level cascaded H-bridge multilevel inverters (CHB MLI) at low switching frequencies. The aim is to analyze the efficiency of a single-phase 9-level cascaded CHB MLI using three distinct switch configurations: 16-switch, 11-switch, and proposed 8-switch. The calculated switching angles are optimized using the feed-forward methodology. Two types of load conditions—R load and R-L load—are being examined. The results suggest that the proposed 8-switch design exhibits superior efficiency by limiting power losses compared to other topologies. Regarding THD, the conventional topology yields a somewhat lower value, however, the disparity is less than 1% when compared to both reduced switch topologies.
Reliability oriented performance evaluation of PV inverter with bifacial panels considering albedos
Authors: Sambu Srikanth , Nayak Byamakesh
Published: October 2024

The recent advancements in the solar photovoltaic technology is bifacial panels. These panels are capable of producing higher energy than their conventional panels by capturing from both front and rear sides. By harvesting solar energy from both the front and rare surfaces of the panels, the load on the inverters can increase. This affects its reliability performance. Nevertheless, inverter is reported as the critical component in the photovoltaic (PV) system. Hence this work presents reliability-oriented performance evaluation of PV inverter with bifacial panels is proposed. A 3-kilowatt photovoltaic system has been considered with yearly mission profile data at Hyderabad, India. This evaluation is carried out under various albedos. Finally, a comparison between monofacial and bifacial PV panel are presented. The results show that the albedo significantly impacts the lifetime of a PV inverter and therefore, the albedo should be considered when designing a bifacial panel's inverter.

Owing to the high cost of installation and operation, distributed flexible AC transmission system (FACTS) technology gives opportunity to provide cost-effective solution in power system operation and control. A distributed static series compensator (DSSC) is a series FACTS device and it is placed equidistantly placed on the existing line to vary the line current. Active power can be controlled in the line with the help of DSSC. This paper presents DSSC for active power flow control to enhance system loadability index and to minimize reactive power generation by generators. Since DSSC is of low power. a small value of reactance is emulated in the line. Large number of DSSC’s are distributed along the transmission line at regular intervals to realize considerable change in the current. A particle swarm optimization is implemented to determine DSSC’s emulated reactance optimally. In this condition, all the lines flowing power in their limits with increased loading condition. Maximum system loadability index is evaluated by employing optimal number of DSSC’s on the line. A multiobjective problem is formulated. One objective function is formed such that no line would become overloaded even when loading is increased. Other objective is formulated to minimize reactive power generation by generators. A compromise solution is investigated for optimally connected of DSSC devices to achieve both the objective functions. IEEE 14 bus system is taken for MATLAB simulation of DSSC compensated system.
A comprehensive review on power quality issues and disturbances mitigation through shunt active power filters
Authors: Chauhan Siddharthsingh K. , Chauhan Vineeta S.
Published: October 2024

In contemporary power systems, power quality (PQ) has become a matter of paramount concern. The challenges associated with PQ extend beyond conventional three-phase systems, encompassing the integration of various distributed generation (DG) sources like renewable energy installations, storage systems, and diverse power generation technologies such as diesel generators and fuel cells. The prevalent adoption of rapid-switching devices within the utility infrastructure has resulted in a surge of harmonics and reactive power disturbances. The increased use of harmonics-producing loads has led to several power quality issues, particularly harmonics. The distortions caused by these power quality issues must adhere to the limits established by international standards. Mitigation of these concerns is critical, and active power filters are a realistic option. However, passive filters have problems such as bulkiness, and resonance with either/both load and utility impedance, and the source impedance affects filtering properties. As a result, active power filters (APF) are designed to address the shortcomings of passive filters. Active power filters (APF) offer several advantages over passive filters, including compact size, enhanced filtering characteristics, dynamic performance, and flexible operation. The control strategy of APF strongly influences the APF performance, efficiency, and reliability. This paper presents a detailed assessment of current active filter control systems, highlighting their key features. The characteristics, performance, applicability, and implementation of various control techniques are explored and investigated.
Phase-locked loop based synchronization schemes for three-phase unbalanced and distorted grid: a review
Authors: Tripathy Poonam , Misra Banishree , Nayak Byamakesh
Published: October 2024

The rapidly growing dispersion of distributed generation systems into the utility grid needs appropriate control techniques to stay interconnected even under abnormal and distorted grid conditions to ensure the overall grid stability. To avoid the loss of renewable energy sources (RES) based power generation, the disintegration of RES with respect to synchronization issues must be prohibited for efficient operation. RES control highly relies on the synchronization technique as it is faster and accurate enough to detect the utility grid variables in terms of amplitude, phase, and frequency. Mostly, the phase-locked loop (PLL) synchronization schemes are utilized for control of RES and monitoring of grid voltage. The dynamics of the grid side converter (GSC) is directly influenced by the performance and design criteria of the PLLs. This paper proposes an overall review of the performances of three phase PLL based grid synchronization methods under diverse weak grid conditions.
Power quality enhancement using fully informed particle swarm optimization based DSTATCOM in distribution systems
Authors: Shankar Moguthala , Kumar R. Senthil
Published: October 2024

To compensate for the reactive power, inverter-based conditioners have been utilized in recent years due to their faster response. Distribution static synchronous compensator (DSTATCOM) has been utilized to enhance power quality in power system that is an inverter-based device that is widely utilized. To control this type of equipment, a proportional integrated (PI) controller has been utilized to control most of the equipment with respect to certain parameters. The performance of the controller basically does not meet the expectations because of the dynamics and nonlinearity of a system parameters. In this present paper, a probabilistic neural network has been used in a controller with a fully informed particle swarm optimization (FIPSO) algorithm to generate a suitable weight for controlling the axes of various parameters of DSTATCOMs. Using MATLAB/Simulink software, simulations were performed, and the responses were monitored with particular regard to the reference reactive parameter. The results are compared. DSTATCOM improves power system damping.
Análise do álbum “Meus caros amigos” como um hipergênero
Authors: Fraga Camila Farias , Barros Laíse Maciel
Published: October 2024

Este artigo tem por objetivo apresentar uma análise do álbum Meus caros amigos de Chico Buarque, lançado em 1976, compreendendo-o como um hipergênero, ou seja, o projeto de dizer realizado no álbum está imbricado na sua relação com cada um dos gêneros que o compõem. Para tanto, buscou-se ancoragem teórica no dialogismo bakhtiniano para o conceito de gênero do discurso e de autoria, procurando dialogar com a noção de hipergênero. Para análise das canções, adotou-se como recurso metodológico o Tetragrama de análise multissemiótica da canção proposto pelo Grupo de Estudos da Canção (GECAN). Observou-se que o projeto de dizer expressa uma unidade de sentido ligada ao conjunto de gêneros que compõem o álbum (hipergênero). Muitas das canções de Meus caros amigos fizeram parte da trilha sonora de filmes e peças teatrais, e refletem o Brasil da década de 1970, entretanto, suas temáticas ainda estão bastante presentes na atualidade.
Alteridade e exclusão: o olhar para o outro no poema e na narrativa
Authors: Taraborelli Luciana , Leite Viviane Mendes
Published: October 2024

This article aims to present two text analytical exercises from the artistic-literary sphere that address increasingly necessary and urgent themes to discuss in the classroom: refugees and black women, minorities that are still absent from many curricula. The analytical exercises of the poem “Army (chusma) of black roses” (2017), written by Cristiane Sobral, and the narrative Two boys of Kakuma (2018), written by Marie Ange Bordas, serve as a proposal for reading activities with students in the final years of elementary education, as they deal with relationships of otherness. These exercises are based on the perspective of Dialogical Discourse Analysis (Brait, 2008), originating from the extensive work on Mikhail Bakhtin and the Circle, in which the other is constitutive of the self. The theoretical foundation is based on the self-other relationship posited by Bakhtin, ([1920/24] 2020) and the concept of otherness (Amorim, 2004). As a result, in our analyses, we point out the centers of values present in literary texts based on the relationship between self and other and, through linguistic-discursive analysis, we lead readers to reflect on themselves and their other.
Uma análise da organização retórica do gênero resenha literária em blogs pessoais
Authors: Araújo Maria Eduarda Diógenes de , Mendes Wellington Vieira , Parnaíba Assidia Maria Soares Alves
Published: October 2024

O avanço tecnológico permitiu o surgimento de novas linguagens e novos gêneros. No âmbito digital, o blog é considerado um hipergênero que permite a publicação de outros gêneros, como é o caso da resenha literária. Este trabalho tem como objetivo analisar a organização retórica de resenhas literárias publicadas em blogs, com base no modelo Create a Research Space (CARS) do pesquisador Swales (1990), e na adaptação desse modelo realizada por Bezerra (2017). Além disso, também é objetivo desta pesquisa perceber como a categoria apreciação, do subsistema atitude – sistema de avaliatividade – evidencia a apreciação do resenhista no momento de avaliar a obra, fundamentando-se na Linguística Sistêmico-Funcional (LSF), a partir de Martin e White (2005). Esta pesquisa se embasa na perspectiva de gênero como ação social, desenvolvida por Miller (2008), considerando, também, pesquisadores como Bakhtin (2016), Bonini (2011) e Motta-Roth (1995), para discussão dos gêneros textuais/discursivos. A pesquisa é descritiva e interpretativista, com caráter qualitativo, e o corpus é constituído por 10 resenhas literárias escritas em inglês e consultadas em blogs pessoais. Os resultados apontam que as resenhas literárias são instanciadas por textos nos quais a escrita permite tanto a norma padrão quanto a forma coloquial. Constatou-se, também, uma nova subunidade retórica “informar sobre/descrever personagens” quanto ao desenvolvimento do gênero pesquisado.
Linguagem e Memória: a construção discursiva da imagem de Prestes e Vargas nas biografias escritas por suas Filhas
Authors: Abreu-Aoki Raquel , Aguiar Marcia Elisia Matos
Published: October 2024

O gênero biográfico, como um gênero narrativo, é um espaço singular para a construção discursiva de uma trajetória de vida. Nesse gênero, a linguagem apresenta-se como um instrumento poderoso de (res)significações de discursos e narrativas, em especial, quando refere-se a biografias de cunho historiográfico. Nessa complexa rede de (outros) sentidos produzidos, a biografia de agentes políticos ilustres potencializa a produção de (novas) perspectivas acerca de eventos históricos e das próprias personalidades políticas. A partir de tal panorama, para este trabalho, foram analisadas as obras Luiz Carlos Prestes, um comunista brasileiro e Getúlio Vargas, meu pai — escritas, respectivamente, por suas filhas Anita Leocádia Prestes e Alzira Vargas do Amaral Peixoto —, cujo enfoque respalda a reconstituição das infâncias dos biografados. À luz das teorias de Charaudeau (2009), a análise comparativa realizada aponta para um lugar em comum entre tais biografias, de modo que as imagens discursivamente construídas dos biografados engajam o público leitor a conceber a fase da infância como um período importante para a formação desses sujeitos e para a expressão de suas identidades. Nesse sentido, os resultados indicam que as representações de Vargas e Prestes sugerem aptidão para suas atuações no cenário político e na História do Brasil.
Transitividade e nominalização: um estudo sistêmico-funcional em redação do Enem
Authors: Santiago Ana Catarina Gomes Farias , Barbosa Maria do Rosário Albuquerque , Sarinho Júnior José Maria de Aguiar
Published: October 2024

Estudar um texto à luz da Linguística Sistêmico-Funcional é analisá-lo juntamente com seu aspecto contextual/pragmático, levando em consideração as funções da linguagem e suas respectivas intenções comunicativas. Sendo assim, a Metáfora Gramatical e, especificamente, a metafunção ideacional, corrobora a defesa do posicionamento crítico em meio à sociedade. Tendo em vista que a produção escrita é uma forma de participação social, o objetivo deste artigo foi verificar os diálogos existentes entre o sistema de transitividade e a nominalização em textos dissertativo-argumentativos, como uma estratégia de persuasão e de impessoalidade do dizer. A pesquisa fundamentou-se em autores como Halliday e Matthiessen (2014), Sardinha (2007), Gouveia (2009) e Valério (2012). Foi examinado um corpus de quatro redações nota mil no formato do Exame Nacional do Ensino Médio (Enem). Os resultados esperados são os de que a Metáfora Gramatical se mostra como um excelente artifício para produções argumentativas.
Desinformação nos meios digitais: formação semiótica e conscientização
Authors: Carvalho Andrey Istvan Mendes
Published: October 2024

O presente trabalho compara a construção do corpo do ator da enunciação em dois sites desinformativos: a capa do site Jornal da Cidade Online, promotor de desinformação, e do site Jornal Tribuna Nacional, propagador de teorias conspiratórias, no dia 20/08/2022, às 18h10. Tal comparação visou verificar e reforçar a noção de que recursos da ordem do sensível podem direcionar a crença no dizer-verdadeiro do discurso, pondo em funcionamento um dispositivo ético (Patte, 1986) que solicita o engajamento dos sujeitos. A análise do corpus considerou as páginas como totalidades discursivas (Discini, 2009), buscando observar recorrências formais compartilhadas pelos discursos conspiratórios e de desinformação. Nesse sentido, dada a importância do conhecimento dessas estratégias para a instituição de um letramento crítico quanto aos discursos de desinformação (Gomes, 2019), tornou-se possível delimitar estratégias de ensino de leitura.

Background

Survival following an out‐of‐hospital cardiac arrest depends on prompt defibrillation. Despite the efforts made to install automated external defibrillators (AEDs) in crowded areas, their usage rate remains suboptimal. This study evaluated the efficiency of installing AEDs at key landmarks in Taoyuan City to enhance accessibility and usage.

METHODS AND RESULTS

This retrospective cohort study analyzed nontraumatic public out‐of‐hospital cardiac arrest cases in Taoyuan City from 2017 to 2021, using data from the Taoyuan Fire Department and a regional registry. AED data were collected for 1163 devices. A geographic information system mapped target locations within the city, and real‐world walking routes were examined to assess coverage. The primary outcome was actual coverage and the coverage efficiency ratio, calculated as the actual coverage divided by the number of facilities at a location. The coverage efficiency ratio compared the coverage efficiency of target locations with existing public access defibrillators (PADs). Top locations for superior coverage in both downtown and outside downtown areas were bus stops and convenience stores (7‐Eleven and FamilyMart), which outperformed existing PADs. Convenience stores had a higher coverage efficiency ratio than the public service sector. Bus stops showed high AED usage rates before ambulance arrival.

Conclusions

The current PAD locations in Taoyuan City offer limited coverage, which highlights the need for strategically installed AEDs, particularly in convenience stores. Policymakers should consider using the cultural relevance and accessibility of convenience stores, particularly 7‐Eleven branches, to enhance AED usage rates.

Published: October 2024

Background

The clinical characteristics and survival outcomes of patients who underwent concomitant coronary artery bypass grafting during septal myectomy have not been well studied.

Methods and Results

We reviewed patients who underwent both septal myectomy and coronary artery bypass grafting from 2009 to 2020. Causes of concomitant grafting and their impact on survival were analyzed. The median follow‐up period was 5.1 years. A total of 320 patients underwent both grafting and myectomy. Of these, 69.7% and 28.1% underwent grafting attributed to atherosclerotic coronary artery disease and myocardial bridging, respectively. Patients who underwent grafting for coronary artery disease tended to be older, had a longer bypass time, and required more grafts compared with patients undergoing procedures because of myocardial bridging (all
P
<0.05). Postoperatively, the left ventricular outflow gradient significantly decreased from 85.4 mm Hg to 12.8 mm Hg (
P
<0.001) without perioperative death. The cumulative survival rates were 96.2% and 97.6% at 5 years in the coronary artery disease and myocardial bridging groups, respectively, and they were comparable to that of general myectomy cohort (hazard ratio [HR], 1.06 [95% CI, 0.47–2.36],
P
=0.895 and HR 0.75 [95% CI, 0.23–2.46],
P
=0.636, respectively). Sudden death accounted for 45.5% (5 of 11) of postoperative mortality. Analysis of composite end point events showed decreased morbidity with at least one arterial graft in the overall cohort (HR, 0.47 [95% CI, 0.23–0.94],
P
=0.034).

Conclusions

Concomitant grafting in septal myectomy was found to be a safe procedure. Patients who underwent such surgery experienced favorable postoperative outcomes comparable to those who underwent septal myectomy alone, with a 5‐year survival rate of >95% and improved functional class of >90%.
Transnational Climate Governance and State Capacity: A Multilevel Analysis of Green Bond Certification
Authors: Lin Jiun-Da
Published: October 2024

Green bonds have become a key instrument for combating the climate crisis. To mitigate the risk of greenwashing, nongovernmental organizations and market participants have established transnational standards and certification schemes for the global governance of green bonds. This research aims to explain the variation in the adoption of certification across bonds and countries. By analyzing a data set of 4,682 green bonds from fifty-five countries between 2016 and 2020, the multilevel mixed-effects models indicate that an increase in participants in the Task Force on Climate-Related Financial Disclosures within a country positively correlates with the likelihood of domestic green bond issuers adopting the certification from the Climate Bonds Initiative (CBI). In countries with stronger state capacity to adopt climate laws and policies, green bond issuers are more likely to participate in the CBI certification. This study has implications for addressing the issue of greenwashing in the development of the green bond market.
High-resolution 7T fMRI reveals the visual zone of the human
claustrum
Authors: Coates Adam , Linhardt David , Windischberger Christian , Ischebeck Anja , Zaretskaya Natalia
Published: October 2024

The claustrum is a thin grey matter structure located between the insular cortex and the putamen. The function of the claustrum is largely unknown with diverse hypotheses ranging from multisensory integration and consciousness to attention and cognitive control. Much research on the function of the claustrum relies on invasive techniques in animal models, as the claustrum’s uniquely thin shape makes it difficult to image non-invasively in human subjects. In the current proof-of-concept study, we used high-resolution ultra-high field (7 Tesla) functional magnetic resonance imaging (fMRI) to measure activity in the human claustrum during the processing of naturalistic stimuli. We presented short video clips as visual only, auditory only, or audiovisual conditions while participants performed a central fixation task. We found distinct visual responses in both the left and the right claustrum at a consistent spatial location across participants, hemispheres, and sessions. We also found deactivations in response to auditory stimulation. These deactivations were confined to the right claustrum and did not overlap with visual activity. The deactivation in response to auditory stimulation demonstrates the complexity of the claustrum’s functional organization and suggests functional differentiation within the claustrum. This is the first study to demonstrate sensory-specific effects within the human claustrum. It opens the possibility for studying the claustrum’s role in higher-level aspects of sensory processing in humans.
No evidence that visual impulses enhance the readout of retrieved long-term memory contents from EEG activity
Authors: van Bree Sander , Mackenzie Abbie Sarah , Wimber Maria
Published: October 2024

The application of multivariate pattern analysis (MVPA) to electroencephalography (EEG) data allows neuroscientists to track neural representations at temporally fine-grained scales. This approach has been leveraged to study the locus and evolution of long-term memory contents in the brain, but a limiting factor is that decoding performance remains low. A key reason for this is that processes such as encoding and retrieval are intrinsically dynamic across trials and participants, and this runs in tension with MVPA and other techniques that rely on consistently unfolding neural codes to generate predictions about memory contents. The presentation of visually perturbing stimuli may experimentally regularize brain dynamics, making neural codes more stable across measurements to enhance representational readouts. Such enhancements, which have repeatedly been demonstrated in working memory contexts, could offer a tool to improve decoding in long-term memory tasks. In this study, we evaluated whether visual perturbations—or pings—improve our ability to predict the category of retrieved images from EEG activity during cued recall. Overall, our findings suggest that while pings evoked a prominent neural response, they did not reliably produce improvements in MVPA-based classification across several analyses. We discuss possibilities that could explain these results, including the role of experimental and analysis parameter choices and mechanistic differences between working and long-term memory.
‘To Each Their Own’
Authors: Palmer Seth
Published: October 2024

In 2014 a violent encounter unfolded at the royal cemetery of Betsioka between Christian evangelists and their antagonists: spirit mediums, shrine caretakers, and monarchical-ancestral spirits (tromba). The narratives provided by members of the Malagasy Church of Jesus Christ, alongside those offered by spirits and their human supplicants, paint an intimate portrait of the two groups’ competing ideologies. The event emerged from longstanding tensions between indigenous Sakalava communities and highlander Protestant migrants who demonize possession rituals attached to the Sakalava monarchical system. Critically, both parties mediated their disagreement through the shared understanding that each individual has a unique destiny and should be free to follow their own religious commitments. Discourse on predestined individual difference challenged the actions of evangelists who saw the ‘traditions of the ancestors’ as incommensurable with Christian life. Increasing Christian nationalism on the island highlights the awkward place that aggressive proselytization occupies in religious rights debates.
The Impact of Incitement by Public Officials in the Commission of Genocide: the Case of Ethnic Amharas in the Oromia Region
Authors: Mengistu Abyssinia Abay
Published: October 2024

Insecurity has worsened in one of the eleven regions of Ethiopia, Oromiya, due to the killings of innocent Amharas. While there is increasing academic attention on the origins, causes, and nature of this threat, the role of the incitement of public officials in the commission of the killings and/or genocide in the region remains understudied. Accordingly, foregrounded by the need to unravel this gap, this qualitative study contributes to the literature through organised empirical research by examining Ethiopia’s public officials’ speeches and/or incitement, which might have helped in the commission of ethnic Amhara genocide in the Oromiya region since 2018. Three critical world events served as the main theoretical foundations for the analysis of incitement to genocide: the Nuremberg Prosecutions, the United Nations Genocide Convention, and the International Criminal Tribunal for Rwanda. It was found that both Prime Minister Abiy’s and Shimelis Abdisa’s speeches have mounted to qualify as incitements to genocide by being concomitant to the context, purpose, and causation. It is thus sufficient to remark that the speeches are used to further instigate genocide against ethnic Amharas. The study’s central argument holds that the causal link between the speech in question and the massacre in the region doubles the synthesis, although the UN Convention does not require a direct causal link.

1. Recréation 3D et création théâtrale contemporaine
Authors: Triolaire Cyril
Published: October 2024

Le Wakan Théâtre, compagnie de théâtre professionnel dirigée par Dominique Touzé, crée en 2011 le spectacle 1759. Ça commence la Comédie ! Cette création met à l’honneur le premier théâtre du Massif central, établi à Clermont-Ferrand en 1759, dans les murs de l’hôtel de ville construit sous l’intendant d’Auvergne Ballainvilliers. Le spectacle intègre la reconstitution en 3D du théâtre, en collaboration avec le cabinet d’architecture Panthéon et 3D Studio EDA . Cet article propose de revenir sur les enjeux de la recréation numérique de ce théâtre disparu à partir de plans de coupe, des dessins des motifs décoratifs de Berinzago, et de plans de ville et d’élévation des bâtiments en deux dimensions. Par-delà la mise en images numériques des sources mobilisées pour ce projet, la confrontation des discours, des architectes 3D, du comédien et de l’historien doivent permettre de réinterroger tout à la fois la matérialité et la mise en espace d’un lieu de spectacle, le lien entre patrimonialisation numérique et création vivante contemporaine, et la portée pédagogique d’un objet une fois le spectacle achevé.

In 2011, the Wakan Theatre, a professional theatre company directed by Dominique Touzé, devised a performance called 1759. Ça commence la comédie ! about the first permanent theatre in the Massif Central, built within the walls of the city hall in Clermont-Ferrand at the behest of Intendant of Auvergne Ballainvilliers in 1759. The show integrates a 3D reconstitution of the theatre created in collaboration with the architectural firm Panthéon and 3D EDA Studio. This article proposes to return to the issues surrounding the digital recreation of this bygone theatre, based on floor plans, drawings of decorative patterns by Berinzago, city maps and elevation drawings. Beyond the digital images created from these sources, Wakan’s work brings together architectural, performance and historical discourses, fostering questions on the materiality and layout of a theatre, the link between digital heritage conservation and contemporary theatrical creation, as well as the pedagogical reach of such works once the show is over.
8. Brève de méthodologie : Archéologie théâtrale en Bretagne. Tentative de reconstitution en 3D du « Vieux Théâtre » de Morlaix.
Authors: Magrou Rafaël
Published: October 2024

À Morlaix, en Bretagne, un théâtre abandonné a suscité l’intérêt d’un groupe d’étudiants de l’École nationale supérieure d’architecture Paris-Malaquais. Durant une semaine, ils ont visité, étudié, relevé, modélisé et ainsi contribué à rendre compréhensibles ces vestiges du XVIIIe siècle, profondément transformés à la fin du XXe siècle. Invisible depuis la rue, son état de délabrement permet de saisir l’essentiel de la composition de la salle, tandis que la partie scénique a totalement disparu. À partir de documents d’archives, d’une enquête sur place et de relevés de détails, les étudiants ont échafaudé des hypothèses de reconstitution à différents moments de ce témoin scénique régional. À l’aide d’outils numériques, ils ont pu, dans un temps restreint, reconstituer en partie cet ouvrage avant que cette construction ne disparaisse totalement (workshop intensif 27 septembre-1 octobre 2021). À l’issue d’une semaine de recoupements et de recollements, ils ont présenté à des élus locaux, à des riverains comme à l’Architecte des Bâtiments de France le résultat certes partiel mais révélateur de l’intérêt de cet ouvrage oublié.

In Morlaix, French Brittany, an abandoned theatre caught the attention of a group of students from the École nationale supérieure d’architecture Paris-Malaquais. Over the course of a week, they visited, studied, surveyed and modelled this eighteenth-century building, which was radically transformed by the end of the twentieth century. Invisible from the street, the dilapidated state of the building allows one to grasp the essence of the room’s composition, while the stage area has completely disappeared. Based on archival documents, an on-site investigation and detailed surveys, the students came up with hypotheses for reconstructing this regional landmark at different points in time. Using digital tools, they were able to redesign part of the structure in a very short space of time (intensive workshop 27 September-1 October 2021), before it disappeared altogether. After a week of cross-checking and piecing together the data, the students presented the fruits of their labour to local councillors, residents and the Architecte des Bâtiments de France (a government official), their admittedly partial results revealing the interest of this forgotten structure.
A Deep Learning Framework for Satellite-Derived Surface PM2.5 Estimation: Enhancing Spatial Analysis in the United States

Published: October 2024

Monitoring fine particulate matter (PM2.5) is crucial for evaluating air quality and its effects on public health. However, the limited distribution of monitoring stations presents a challenge in accurately assessing air pollution, especially in areas distant from these stations. To address this challenge, our study introduces a two-step deep learning approach for estimating daily gap-free surface PM2.5 concentrations across the contiguous United States (CONUS) from 2018 to 2022, with a spatial resolution of 4 km. In the first phase, we employ a depthwise-partial convolutional neural network (DW-PCNN) to fill gaps between surface PM2.5 stations, utilizing aerosol optical depth (AOD) data from the Moderate Resolution Imaging Spectroradiometer (MODIS). In the second phase, we integrate the PM2.5 grids imputed by the DW-PCNN with meteorological and anthropogenic variables into a deep convolutional neural network (Deep-CNN) to further enhance the accuracy of our estimation. This enables us to estimate gap-free surface PM2.5 concentrations accurately, evidenced by Pearson’s correlation coefficient R of 0.92 and an index of agreement (IOA) of 0.96 in 10-fold cross validation. We also introduce a grid-based method for calculating PM2.5 design values (DVs), providing a continuous spatial representation of PM2.5 DV that enhances the traditional station-based approach. Our grid-based DV representations offer a comprehensive perspective on air quality, facilitating more detailed analysis. Furthermore, our model’s ability to provide spatiotemporally consistent, gap-free PM2.5 data addresses the issue of missing values, supporting health impact research, policy formulation, and the accuracy of environmental assessments.

With global warming becoming more and more serious, the global need for low-carbon economic transition is increasingly urgent. This study focuses on the time–frequency spillover effect of climate risk perception and energy market. By constructing transition risk perception and physical risk perception indices and using time–frequency analysis, we quantify the impact of climate risk perception on fossil energy and clean energy markets and reveal the dynamic relationship between them. The findings indicate that China’s perception of transition risk from climate change has increased since the Paris Climate Agreement, but the perception of physical risk has changed less. Moreover, the spillover effect between climate risk perception and energy markets is time varying and increases rapidly in the face of climate- or energy-related uncertain events. The COVID-19 pandemic has resulted in a sharp drop in total spillover, and there is little near-information spillover between energy markets and perceptions of climate danger. We also found that in the short term, energy market spillovers are net recipients of climate risk perception according to marginal spillover research. However, this connection changes to become a net transmitter in 2021. In the medium-to-long term, the perception of climate risk begins to function as a net transmitter of spillovers to energy markets.
How Radio Affects Violent Conflict: New Evidence from Rwanda

Published: October 2024

Researchers have long debated how radio broadcasts affected the dynamics of the 1994 genocide in Rwanda, with some arguing that the radio was highly consequential, and others suggesting such effects have been overstated. This article contributes to these debates—as well as to debates regarding the role of old and new media in collective action—by examining whether and how Radio Télévision Libre des Mille Collines (Radio RTLM) coverage was associated with two core aspects of the violence: (1) subnational onset of genocidal violence and (2) participation in genocidal violence across subnational spaces. Drawing on new data on Radio RTLM coverage, we find that areas with coverage were more likely to experience immediate onset of violence. However, our analysis of participation in the genocide—which uses more accurate measures of participation and of radio coverage than prior studies—finds no significant association between Radio RTLM coverage and subnational levels of participation. After illustrating that these results are robust to numerous model specifications, we theorize that information broadcast over the radio’s airways contributed to the creation of a critical mass that initiated genocide in localized spaces. We conclude by considering the importance of understanding the role of media in the subnational onset of violence.

Current interventions for oral/dental diseases heavily rely on operative/surgical procedures, while the discovery of novel drug targets may enable access to noninvasive pharmacotherapy. Therefore, this study aims to leverage large-scale data and Mendelian randomization (MR) techniques, utilizing genetic variants as instruments, to identify potential therapeutic targets for oral and dental diseases supported by genetic evidence. By intersecting 4,302 druggable genes with expression quantitative trait loci from 31,684 blood samples, we identified 2,580 druggable targets as exposures. Single nucleotide polymorphisms associated with dental disease/symptom traits were collected from FinnGen R9, the Gene–Lifestyle Interactions in Dental Endpoints consortium, and the UK Biobank to serve as outcomes for both discovery and replication purposes. Through MR analysis, we identified 43 druggable targets for various dental disease/symptom traits. To evaluate the viability of these targets, we replicated the analysis using circulating protein quantitative trait loci as exposures. Additionally, we conducted sensitivity, colocalization, Gene Ontology/Kyoto Encyclopedia of Genes and Genomes annotation, protein–protein interaction analyses, and validated dental trait–associated druggable gene expression in animal models. Among these targets, IL12RB1 (odds ratio [OR], 1.01; 95% confidence interval [CI], 1.01–1.01) and TNF (OR, 0.98; 95% CI, 0.97–0.99) exhibited therapeutic promise for oral ulcers, whereas CXCL10 (OR, 0.84; 95% CI, 0.76–0.91) was for periodontitis. Through a rigorous quality control and validation pipeline, our study yields compelling evidence for these druggable targets, which may enhance the clinical prognosis by developing novel drugs or repurposing existing ones.
To Praise or Pressure? Patterns of Social Media Advocacy in Times of COVID-19
Authors: De Bruycker Iskander
Published: October 2024

This article explores how interest groups harness social media as a tool for either praising or pressuring their government. On one hand, social media provides an ideal platform for exerting external pressure on the government, enabling outreach to a wide range of citizens, journalists, and supporters. On the other hand, it offers interest groups the opportunity to support their allies and applaud government policies, fostering reciprocal trust and strengthening mutually beneficial long-term relationships with policymakers. The article argues that the positioning of interest groups on social media is driven by the political and policy opportunity structures in which they operate. Empirically, the article relies on an analysis of 3,897 hand-coded X-posts from prominent hospitality associations in nine Western democracies during the COVID-19 pandemic. The findings demonstrate that interest groups tend to employ pressure tactics when real-world conditions are advantageous to their cause, while turning to praise when favorable government policies are adopted.

This narrative review investigates the advancements of metal nanoparticles in cancer treatment, types and mechanisms in targeting cancer cells, application in clinical scenarios, and potential toxicity in medicine.
From Chateau Latour to Chateau Bourdieu: The sociology of wine between empire, class, ethnicity and gender (or, the oenologic of practice)
Authors: Inglis David , Almila Anna-Mari
Published: October 2024

Many sociologists drink wine, but hardly any write about it professionally, and the putative scholarly field of the ‘sociology of wine’ remains inchoate, the study of wine mostly being ceded to other disciplines. This is strange, as wine is crucial to a host of phenomena, such as national and regional identities in winemaking countries, as well as identity construction and class-based distinction dynamics in many other locations. Wine has received relatively little attention from Bourdieu or those inspired by him. Indeed, some of the most influential writings on wine in a sociological register today are sometimes explicitly hostile to his sociology. Yet for all types of activities traversing the overlapping domains of the production, social distribution and consumption of wine, Bourdieusian elements must be brought into the analysis to be able to appreciate interlocking issues of class, ethnicity and gender relations and inequalities, particularly within imperial/colonial and post-imperial/post-colonial social contexts. In its 8000-year history, very major factors in the social structuring of wine have been imperial power and colonial expansion, factors bound up with ethnic and gender inequalities in wine phenomena both historically and today. A flexible and open-minded version of Bourdieu, as advocated by Bridget Fowler, draws attention to ongoing dynamics of power and resistance in wine worlds.

Published: October 2024

In this study, we investigate the temporal and spatial evolution of wetting saturation during spontaneous imbibition in anisotropic fibrous porous media using both experimental and numerical methods. We present a novel experimental approach to systematically study spontaneous imbibition in these media, allowing for a comprehensive assessment of how microstructure influences wicking performance. The experimental method, which exhibits high reproducibility, was used to validate the numerical model. The numerical model was parameterized using only the porosity and filament diameter of the porous media in conjunction with the material properties of the imbibing fluid. The essential capillary saturation curve for the numerical model was derived using the pore morphology method. The numerical results effectively replicated the experimental results.

Our experimental and numerical observations revealed a diffusive wetting front within the porous media, which progressively expanded and decelerated during the imbibition process. The results highlight the significant influence of filament size on the wetting saturation dynamics and the height of the wetting front during spontaneous imbibition.
