Recent observations of galaxy clusters and groups with misalignments between their central active galactic nucleus jets and X-ray cavities, or with multiple misaligned cavities, have raised concerns about the jet–bubble connection in cooling cores, and the processes responsible for jet realignment. To investigate the frequency and causes of such misalignments, we construct a sample of 16 cool core galaxy clusters and groups. Using Very Long Baseline Array radio data, we measure the parsec-scale position angle of the jets, and compare it with the position angle of the X-ray cavities detected in Chandra data. Using the overall sample and selected subsets, we consistently find that there is a 30%–38% chance to find a misalignment larger than ΔΨ = 45° when observing a cluster/group with a detected jet and at least one cavity. We determine that projection may account for an apparently large ΔΨ only in a fraction of objects (∼35%), and given that gas dynamical disturbances (such as sloshing) are found in both aligned and misaligned systems, we exclude environmental perturbation as the main driver of cavity–jet misalignment. Moreover, we find that large misalignments (up to ∼90°) are favored over smaller ones (45° ≤ ΔΨ ≤ 70°), and that the change in jet direction can occur on timescales between one and a few tens of Myr. We conclude that misalignments are more likely related to actual reorientation of the jet axis, and we discuss several engine-based mechanisms that may cause these dramatic changes.
First JWST Observations of JAGB Stars in the SN Ia Host Galaxies: NGC 7250, NGC 4536, NGC 3972

Published: January 2024

The J-region Asymptotic Giant Branch (JAGB) method is a standard candle that leverages the constant luminosities of color-selected, carbon-rich AGB stars, measured in the near-infrared at 1.2 μm. The Chicago-Carnegie Hubble Program has obtained JWST imaging of the SN Ia host galaxies NGC 7250, NGC 4536, and NGC 3972. With these observations, the JAGB method can be studied for the first time using JWST. Lee et al. demonstrated the JAGB magnitude is optimally measured in the outer disks of galaxies, because in the inner regions the JAGB magnitude can vary significantly due to a confluence of reddening, blending, and crowding effects. However, determining where the “outer disk” lies can be subjective. Therefore, we introduce a novel method for systematically selecting the outer disk. In a given galaxy, the JAGB magnitude is first separately measured in concentric regions, and the “outer disk” is then defined as the first radial bin where the JAGB magnitude stabilizes to a few hundredths of a magnitude. After successfully employing this method in our JWST galaxy sample, we find the JAGB stars are well segregated from other stellar populations in color–magnitude space, and have observed dispersions about their individual F115W modes of σ
N7250 = 0.32 mag, σ
N4536 = 0.34 mag, and σ
N3972 = 0.35 mag. These measured dispersions are similar to the scatter measured for the JAGB stars in the LMC using 2MASS data (σ = 0.33 mag). In conclusion, the JAGB stars as observed with JWST clearly demonstrate their considerable power both as high-precision extragalactic distance indicators and as SN Ia supernova calibrators.
GeV Variability Properties of TeV Blazars Detected by Fermi-LAT
Authors: Wang Gege , Xiao Hubing , Fan Junhui , Zhang Xin
Published: January 2024

Variability is a prominent observational feature of blazars. The high-energy radiation mechanism of jets has always been important but is still unclear. In this work, we performed a detailed analysis using Fermi-LAT data across 15 yr and obtained GeV light-curve information for 78 TeV blazars detected by Fermi. We provided annual GeV fluxes and corresponding spectral indices for the 78 TeV blazars and thorough monthly GeV fluxes for a subsample of 41 bright blazars. Our results suggest a strong correlation between the γ-ray photon index and

log

L

γ

for the flat spectrum radio quasars (FSRQs) and high-energy peaked BL Lacs. Fourteen sources in our sample show significant GeV outbursts/flares above the relatively stable, low-flux light curve, with six of them showing a clear sharp peak profile in their 5 day binned light curves. We quantified the variability utilizing the fractional variability parameter F
var, and found that the flux of the FSRQs showed significantly stronger variability than that of the BL Lacs. The 41 bright blazars in this work are best fit by a log-normal flux distribution. We checked the spectral behavior and found 11 out of the 14 sources show a bluer-when-brighter trend, suggesting this spectral behavior for these TeV blazars at the GeV band arises from the mechanism in which the synchrotron-self Compton process dominates the GeV emission. Our research offers a systematic analysis of the GeV variability properties of TeV blazars and serves as a helpful resource for further associated blazar studies.
Snapshots of an Evolving Solar Nebula Recorded in Nucleosynthetic Sr and Ba Signatures of Early Condensates
Authors: Marquez R. T. C. , Charlier B. L. A. , Tissot F. L. H.
Published: January 2024

The discovery of extreme strontium isotope anomalies (μ
84Sr) in refractory leachates from Allende fine-grained calcium-aluminum-rich inclusions (CAIs) is at odds with long-standing predictions regarding the homogenization of presolar components in the CAI-forming region. Elucidating the stellar source(s) of these phases and the mechanisms for their preservation holds potential significance in understanding the dynamics and evolution of the protoplanetary disk. Here we present barium isotope data for the same set of leachates previously analyzed for μ
84Sr. Our results show fairly homogeneous Ba isotope anomalies across leachates (∼100–200 ppm variability), in contrast to the observed μ
84Sr variations (up to ∼8%). Secondary phases extracted in earlier leaching steps (L1 and L3) reveal trends in μ
137Ba and μ
138Ba akin to that of mainstream SiC and a second nucleosynthetic component. We show that SiC X grains from Type II supernovae are good end-member candidates for explaining the intra-leachate spread in L1 and L3 μ
13x
Ba. Notably, neither s-variability nor X-variability appears to contribute to trends in the barium isotope anomalies of the most refractory components (L4 and L5). We propose that the contrast in isotope anomaly systematics between the labile and refractory leachates could reflect a shift in the nucleosynthetic signatures of reservoirs sampled by these components. These observations are consistent with extreme 84Sr p-excesses manifesting only in L4 and L5 leachates. Finally, the decoupled Sr and Ba isotope anomalies point to a nucleosynthetic source that significantly overproduces strontium relative to barium, such as electron-capture supernovae or the collapse of rotating massive stars.

Published: January 2024

Introduction: Tuberculosis (TB) is one of the top ten causes of death in the world. The purpose of this study was to explore the relationship between the short-term exposure to air pollutants and the risk of pulmonary TB in Chongqing.
Methodology: A distributed lag nonlinear model was used to explore the effect of short-term exposure to air pollutants on the risk of pulmonary TB. Stratified analysis was used to explore the impact of gender and age on the risk of pulmonary TB.
Results: There were 170,934 confirmed cases of pulmonary TB in Chongqing from January 1st, 2014 to December 30th, 2020. There was a positive correlation between the exposure to particulate matter with aerodynamic diameter less than 2.5 µm (PM2.5), particulate matter with aerodynamic diameter less than 10 µm (PM10) ozone (O3) and the incidence risk of TB. The maximum lag-specific relative risk (RR) of pulmonary TB was 1.012 (95% CI: 1.001-1.023, 14 days delay) for each 10 μg/m3 increase in PM2.5; 1.010 (95% CI: 1.003-1.017, 14 days delay) for each 10μg/m3 increase in PM10; and 1.002 (95% CI:1.000-1.004, 2 days delay) for each 10 mg/m3 increase in O3. Stratified analysis showed that the exposure effects of PM2.5, PM10 and O3 were different between different genders and age.
Conclusions: This study suggested that exposure to PM2.5, PM10, and O3 was associated with the risk of pulmonary TB, and the risk was higher for males than females, while the exposure to PM2.5 and PM10 was riskier for people aged 15-60 years.
Prevalence and risk factors associated with tuberculosis and HIV coinfection in Iran: A multivariate firth logistic regression for rare events
Authors: Mirahmadizadeh Alireza , Sharafi Mehdi , Hassanzadeh Jafar , Seif Mozhgan
Published: January 2024

Introduction: Among the complications caused by HIV infection, tuberculosis (TB) is the most important challenge. The study aimed to determine the predictors of TB and HIV coinfection by using Firth logistic regression analysis.
Methodology: This cross-sectional study was conducted on 32,168 HIV-positive patients diagnosed in Iran. The required information was obtained from the national HIV/AIDS surveillance data.
Results: The prevalence of TB in HIV patients was 3.2%; the prevalence of TB in males and females was 944 (91.83%) and 84 (8.17%), respectively. Based on results of multivariate Firth logistic regression, male gender OR male/female = 1.91; injecting drug use (IDU) OR YES/NO = 1.46; illiterate or primary groups OR illiterate or primary /university = 2.23; high school group OR high school/ university = 2.24 all increased the risk of TB and HIV coinfection (p < 0.05). Also, having CD4 > 500 [OR CD4 > 500 / < 200 = 0.39], CD4 351-500 [OR351 / < 200 = 0.65], and CD4 200-350 [OR200-350 / < 200 = 0.64] decreased the risk of TB and HIV coinfection (p < 0.001).
Conclusions: According to the results of this study, male gender, low education, injecting drug users, and low CD4 count at the time of diagnosis, were significant predictors of TB and HIV coinfection. Therefore, regular and periodic screening programs and linkage to the care and treatment of HIV patients need special attention.

Published: January 2024

Introduction: The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in around 1 million COVID-19 infection cases and over 29,000 deaths in Tunisia thus far. There is great variability in the prevalence of asthma among patients with COVID-19, but the impact of asthma on patients with COVID-19 is not clear. We sought to describe the clinical features of Tunisian patients with COVID-19 and to compare asthmatic and non-asthmatic patients.
Methodology: This retrospective study included 675 Tunisian patients who were hospitalized with COVID-19. Clinical characteristics were collected from medical records. Bivariate analyses and multivariate regression models were used to assess the associations between asthma and the risk of severe symptoms, including death/recovery.
Results: The prevalence of asthma in the sample was 14.5%. The results show that asthmatic patients with COVID-19 have significantly less severe symptoms and better outcomes than non-asthmatic patients.
Conclusions: Asthma was not found to be associated with higher severity or worse prognosis among patients with COVID-19 in Tunisia.
Rare complication spontaneous pneumothorax and pneumomediastinum in COVID-19 patients: A single center experience
Authors: Tüzün Türkan , Ekinci Yasin
Published: January 2024

Introduction: We aimed to describe the clinical characteristics and outcomes of patients with spontaneous pneumothorax (SPT) and pneumomediastinum (SPM) due to COVID-19 pneumonia.
Methodology: This retrospective study evaluated inpatients at a COVID-19 pandemic hospital. Between March 11, 2020 and March 31, 2021, patients who developed complications of spontaneous pneumothorax (SPT) and pneumomediastinum (SPM) with a confirmed diagnosis of SARS-CoV-2 by polymerase chain reaction (PCR) method were included.
Results: Of the 6,528 hospitalized patients, nine developed complications of SPT and SPM, with an incidence of 0.14%. Four of these patients developed SPT, one developed SPM, one developed SPT + SPM + emphysema, and three developed SPT + SPM. The mean age of the patients was 67.67 ± 13.41 years and the median was 68 (45-88) years. All patients were male. Six patients died, one of whom died of myocardial infarction from uncomplicated causes.
Conclusions: Studies with more cases are needed to evaluate the causality between COVID-19 and pneumothorax (PT) and pneumomediastinum (PM). However, it should be kept in mind that PT and PM may lead to this clinic when sudden respiratory distress occurs in these patients and rapid diagnosis and treatment should be planned. As observed in this study, PT and PM are important factors in the development of mortality in COVID-19 patients.

Traffic flow prediction with a multi-dimensional feature input: A new method based on attention mechanisms
Authors: Zhang Shaohu , Ma Jianxiao , Geng Boshuo , Wang Hanbin
Published: January 2024

Accurately predicting traffic flow is an essential component of intelligent transportation systems. The advancements in traffic data collection technology have broadened the range of features that affect and represent traffic flow variations. However, solely inputting gathered features into the model without analysis might overlook valuable information, hindering the improvement of predictive performance. Furthermore, intricate dynamic relationships among various feature inputs could constrain the model's potential for further enhancement in predictive accuracy. Consequently, extracting pertinent features from datasets and modeling their mutual influence is critical in attaining heightened precision in traffic flow predictions. First, we perform effective feature extraction by considering the temporal dimension and inherent operating rules of traffic flow, culminating in Multivariate Time Series (MTS) data used as input for the model. Then, an attention mechanism is proposed based on the MTS input data. This mechanism assists the model in selecting pertinent time series for multivariate forecasting, mitigating inter-feature influence, and achieving accurate predictions through the concentration on crucial information. Finally, empirical findings from real highway datasets illustrate the enhancement of predictive accuracy attributed to the proposed features within the model. In contrast to conventional machine learning or attention-based deep learning models, the proposed attention mechanism in this study demonstrates superior accuracy and stability in MTS-based traffic flow prediction tasks.
Highways to Silence Revisited: A History of Discourse Coalitions around Traffic Noise
Authors: Bijsterveld Karin , Van Lente Harro
Published: January 2024

During the Covid-19 pandemic, the density of road traffic in the Global North decreased considerably. For those enjoying the resulting tranquillity, it prompted the hope that this experience would raise public noise awareness and alter mobility culture. Now that Global North economies are returning to pre-pandemic levels, however, not much appears to have changed. This article aims to contribute to understanding the persistence of the status quo by historically tracing discourse coalitions around traffic noise in the twentieth and early twenty-first century. Discourse coalitions are connections between groups of actors that have opposing interests but share a specific set of storylines concerning a public problem. As we will show by focusing on the issue of traffic noise in the Netherlands, the long-term results of these discourse coalitions -in terms of discourse structuration, institutionalization and destabilization- tend to shift attention away from structural interventions in traffic flows.
La resignificación del espacio urbano a través de la música pop mainstream
Authors: Viñuela Suárez Eduardo
Published: January 2024

La música popular ha funcionado en numerosas ocasiones como una herramienta para articular discursos y lanzar mensajes que desafían los valores de una sociedad. Más allá de repertorios musicales con un explícito mensaje político, existen numerosos ejemplos que desde el mainstream y a través de estrategias más sutiles envían mensajes que resultan subversivos y generan debates sobre convenciones que han sido normalizadas en nuestra cultura. En los últimos años, la proliferación de las redes sociales ha incrementado el papel de la música en las discusiones políticas, y el crecimiento del consumo musical audiovisual a través de YouTube y las redes sociales ha convertido a los videoclips en un soporte fundamental para dar forma a estos mensajes.
En este artículo analizamos cómo se utiliza el espacio urbano en la música mainstream para articular discursos capaces de generar debate en la sociedad. Partimos de una concepción dual (física y simbólica) del espacio urbano para entenderlo como un constructo social cargado se significados, y abordamos su funcionamiento en la música popular estudiando casos recientes, como la representación de espacios e imaginarios religiosos en los videoclips mainstream.
Ecología Aural: una investigación categorial en sistemas autoorganizados
Authors: Claramonte Jordi , Mateos Ana
Published: January 2024

En este trabajo exponemos algunas categorías modales orientadas al estudio y comprensión de los sistemas autoorganizados que muestran complejidad. Para ello centramos nuestra investigación en el área de la ecología y, más en particular, en el ámbito de la ecología aural, es decir, en el estudio de los sonidos que componen los ecosistemas. Las categorías modales aquí desarrolladas son, por un lado, la «repertorialidad», referida a la coherencia y estabilidad interna de todo sistema autoorganizado; la «disposicionalidad» o experimentación y variación inherente a estos sistemas y, finalmente, el «paisaje», que tiene en consideración lo realmente efectivo, lo dado. Este conjunto de categorías nos lleva a explorar el sistema modal de necesidad-contingencia-posibilidad-imposibilidad, el cual, aplicado a los estudios sonoros se convierte en el juego de señales-redundancia-ruido-silencio. Estas categorías, aplicadas a ejemplos en la naturaleza, nos ayudan a comprender el devenir inherente a todo ecosistema. Finalmente, descubrimos cómo la investigación categorial de los paisajes sonoros aporta información sobre el comportamiento evolutivo y el estado de conservación de estos sistemas.

L’Éducation sentimentale : genèse de la rencontre entre Frédéric et Mme Arnoux
Authors: Calvez Éric Le
Published: January 2024

La rencontre entre Mme Arnoux et Frédéric Moreau, personnages principaux de L’Éducation sentimentale, est prévue très tôt dans sa genèse, dès les premiers scénarios, ce qui est bien prévisible dans le cas d’un roman d’amour. Elle est associée au motif de l’eau et ensuite du voyage dans une scène qui n’est plus statique, comme au début. Elle subit de nombreuses variations, ce qui est là encore inévitable, mais dans l’ensemble on peut en conclure que Flaubert n’a pas peiné longtemps pour la rédiger car son mouvement est trouvé assez vite.
« Bois ! ». La rencontre fatale entre Salammbô et Mâtho dans les transpositions iconiques du roman
Authors: Donatelli Bruna
Published: January 2024

La rencontre entre Salammbô et Mâtho, les deux protagonistes du roman carthaginois de Flaubert, est marquée par un geste audacieux de la fille d’Hamilcar Barca qui coûtera la vie à tous les deux. Lors d’un festin des mercenaires révoltés de ne pas avoir reçu la rémunération convenue, la princesse carthaginoise offre une coupe de vin au chef libyen avec des intentions peu claires : attirance fatale ou stratagème pour apaiser la colère des mercenaires ? La progression des avant-textes du roman indique une hésitation à cet égard. Le geste de Salammbô n’est donc pas accidentel dans l’économie du roman. La coupe est, en effet, un dispositif stylistique de première importance qui alimente et innerve la trame narrative, entrainant désir, pouvoir, sexe et mort. Flaubert s’est inspiré pour cette scène de l’Histoire des Gaulois d’Amédée Thierry qui avait souligné comment, pour ces peuples de l’Antiquité, ce geste correspondait symboliquement au choix d’un fiancé et d’un futur mari par une femme. Évoqué dans le roman par les mots de certains mercenaires présents au festin, le geste de Salammbô reste cependant entouré d’une aura de sacralité et de mystère qui laisse volontairement le lecteur déconcerté. Il est donc difficile de restituer sa transposition par l’image. En effet, dans les narrations iconiques du roman, cette première et fugace rencontre entre les deux est souvent reléguée au second plan, privilégiant plutôt la scène d’amour et de violence sous la tente du mercenaire. Parmi les nombreuses éditions illustrées du roman et celles de son adaptation en bande dessinée, l’article propose les transpositions iconiques de Rochegrosse, Bussière, Blaine, Lagneau et Druillet, des interprètes à la grande sensibilité littéraire qui ont su mettre en valeur la scène en question et établir un pacte de complicité et un dialogue avec le texte qui ouvre sur des relectures nouvelles et originales.

À partir de l’analyse des scènes de première rencontre dans deux adaptations cinématographiques de Madame Bovary — le film de Claude Chabrol avec Isabelle Huppert (1991) et celui de Sophie Barthes avec Mia Wasikowska (2014) — cet article se propose de mettre en évidence les recompositions de l’héroïne qu’elles proposent, partant les reconfigurations de l’intrigue et des enjeux du récit.
Le rendez-vous manqué de Bouvard et Pécuchet avec la peinture
Authors: Dord-Crouslé Stéphanie
Published: January 2024

Flaubert avait-il prévu d’inclure un chapitre sur les beaux-arts, voire sur la seule peinture, dans son dernier roman ? Certains éléments du dossier génétique de Bouvard et Pécuchet permettent de le penser mais leur examen approfondi cantonne ce dessein au stade le plus ancien de la conception scénarique du roman. L’écrivain a ensuite supprimé aussi bien la mise en pratique que l’examen critique de la peinture par ses deux personnages, laissant à la littérature la première place, y compris lorsqu’il s’agissait de penser les deux domaines esthétiques en interaction comme le montre l’utilisation que Flaubert fait des notes qu’il a relevées à la lecture des Réflexions critiques sur la poésie et sur la peinture par l’abbé Dubos (1733).

La consultation de l’avant-texte de Madame Bovary concernant la scène de première vue entre Charles et Emma s’est révélée très précieuse et éclairante car elle nous a permis d’analyser la genèse de cette rencontre dans l’imagination de Flaubert et d’examiner comment l’écrivain a opéré à travers les allusions, la représentation symbolique des objets et les non-dits.
Imaginaires de la masculinité dans les vidéoclips de coupé-décalé (Paris/Abidjan)
Authors: Kolé Mahesse , Andrieu Sarah , Ettien Adou Stéphane
Published: January 2024

Phénomène musical et chorégraphique qui apparaît au début des années 2000 à Paris au sein de la diaspora ivoirienne, le coupé-décalé est rapidement « rapatrié » à Abidjan et avec lui le mode de vie hédoniste et ostentatoire qui lui est intimement relié. Résolument tourné vers la fête et le plaisir, le coupé-décalé se tient loin des crises politiques qui agitent alors le pays. Il s’érige également comme une musique virile au sein de laquelle le corps musclé et athlétique, le look, la voix et les textes mettent en avant les caractéristiques d’une masculinité centrée sur la force, le courage et le goût du risque. Dans ce contexte, le vidéoclip constitue un outil puissant pour la diffusion d’imaginaires genrés auprès de la jeunesse ivoirienne. À partir d’un corpus de vidéoclips et de données issues d’enquêtes de terrain, cet article examine la manière dont les vidéoclips de coupé-décalé mettent en circulation des imaginaires de la masculinité qui répondent tout autant à un désir de bousculer les normes locales que de s’inscrire dans des styles de vie ouverts sur le monde.
Les codes d’une masculinité « cool » : discours et performances de genre dans les clips du rappeur MC Solaar
Authors: Heysch de la Borde Clara
Published: January 2024

Au début des années 1990, les médias généralistes érigent MC Solaar en « rappeur cool » pour le caractère mélodieux et cérébral de sa musique (Hammou, 2012). Cet article, centré sur les clips du rappeur parus au cours de cette décennie, analyse ses performances de genre comme empruntant aux codes d’une masculinité hégémonique (Connell, 1985) proches de la virilité-privilège (Achin et Dorlin, 2008). Bien que ces performances aient servit d’appui aux discours des médias généralistes dans leur rejet des masculinités marginalisées (Connell, 1985) associées aux jeunes de « banlieue », l’analyse propose de les replacer dans une stratégie de contournement de stigmates raciaux de la part de l’artiste. Introduit par une revue de littérature consacrée au traitement académique des masculinités dans le rap français, cet article s’inscrit dans le champ des cultural studies et déploie une analyse textuelle, musicale et visuelle de la masculinité performée par MC Solaar. Les codes de genre du rappeur sont interrogés dans une perspective intersectionelle et à l’aune de la construction globale de sa persona liée à des chaînes de coopération (Becker, 1988) agissant dans le contexte socio-historique précis des années 1990.
"[...] e saranno buoni coloni utili al paese"
Authors: Vanin Alex Antônio , Bertagna Federica
Published: January 2024

O presente artigo visa tratar da correlação existente entre a colonização privada e a catequese indígena levadas a cabo no nordeste do Rio Grande do Sul, no Toldo do Fachinal, então município de Lagoa Vermelha. Problematiza-se em torno da paridade entre os processos de colonização privada com colonos de origem europeia de atuação dos missionários da Ordem dos Frades Menores Capuchinhos na região nesse avanço de ambos sobre um território indígena Kaingang. Por meio de fontes diversas, como correspondências dos capuchinhos e de agentes dos governos estadual e federal, busca-se compreender a colonização, sua correlação com os missionários e a correlação de ambos no projeto de catequese indígena. De duração efêmera, a catequese indígena no Toldo do Fachinal permaneceu por pelo menos duas décadas dentro do horizonte de expectativa dos missionários capuchinhos e visou corroborar empreender um processo de transformação do nativo em um trabalhador rural.
The Need for Explainable AI in Industry 5.0
Authors: Khan Azeem , Jhanjhi Noor Zaman , Hamid Dayang Hajah Tiawa Binti Awang Haji , Omar Haji Abdul Hafidz bin Haji
Published: January 2024

As we enter the era of Industrial Revolution 5.0 (IR 5.0), the role of artificial intelligence (AI) in various domains such as manufacturing, military, healthcare, education, and entertainment is becoming increasingly vital. However, the growing complexity and opacity of AI systems have led to a problem known as the “black box,” which hinders trust and accountability. This is where explainable AI (XAI) comes in, providing a set of processes and methods that enable human users to understand and trust the results and output produced by machine learning algorithms. By describing AI models, their expected impact, and potential biases, XAI helps ensure accuracy, fairness, transparency, and accountability in AI-powered decision making. In this chapter, the authors argue that XAI is indispensable for IR 5.0, as it enables humans to collaborate with AI systems effectively and responsibly. The authors reviewed the current state of XAI research and practice and highlighted the challenges and opportunities for XAI in IR 5.0.
Explainable Artificial Intelligence as a Cybersecurity Aid
Authors: Doshi Ruchi , Hiran Kamal Kant
Published: January 2024

Within the span of just a few short years, artificial intelligence (AI) methods have spread across every facet of modern society. Even though AI models produce results, those results are often not easily explicable. XAI, or “explainable artificial intelligence,” is a rapidly expanding area of study that aims to maximise the clarity of data extraction and visualisation processes. At the heart of the current investigation is an examination of the connections between cybersecurity and the application of XAI. The increasingly sophisticated and automated nature of attacks necessitates similarly mechanised approaches to defence. Due to its unique characteristics, XAI is suitable for this purpose. Cybersecurity is the practise of safeguarding computer systems, networks, and software from intrusion. An enormous amount of hope rests on the shoulders of XAI for foreseeing such assaults.

In this research, sodium-ion cathode batteries based on sodium iron phosphate and the water-chitosan slurry were successfully synthesized with the sol-gel method. The result of the X-Ray Diffraction (XRD) test confirmed the two phases of sodium iron phosphate, which are Na3Fe2(PO4)3 and Na3Fe3(PO4)4, with the percentage weight of the phases of 31.19% and 68.81%, respectively. Then, this sample was examined using Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX) test, it is known that the morphology of particles look like agglomerate thin sponges and no other elements besides Na, Fe, P, and O were found in the sample. Cyclic Voltammetry (CV) dan Electrical Impedance Spectroscopy (EIS) tests were also carried out to determine the electrochemical performance of the cathode material. The CV test was carried out to determine the specific capacity value of each sample. From the test results, it is known that sodium iron phosphate cathode with PVDF binder had a higher specific capacity value than cathode with chitosan binder, which was 44.13 mAh/g and 26.78 mAh/g, respectively. From the EIS results, it was found that sodium iron phosphate cathode with chitosan binder had better electrical conductivity and Na+ ion diffusion, with values of 7.44×10-3 S.cm-1 and 1.48×10-11 cm2 s-1 respectively.

Published: January 2024

This study examined the use of sodium acetate salt as an ionic dopant in biodegradable solid polymer electrolyte (SPE). In the solution casting method for making polymer electrolyte, rice starch is used as the host polymer and glycerol is used as the plasticizer. The characteristics of SPE film were investigated using X-Ray Diffraction (XRD), Fourier Transform Infrared (FT-IR), and Thermogravimetric Analysis (TGA). Salt enhances the amorphous structure by decreasing the crystallinity of the polymer. Alternatively, it decreases the temperature of thermal breakdown. In addition, the biodegradability of SPE was investigated using the soil burial method. Electrochemical Impedance Spectroscopy (EIS) was used to evaluate the ionic conductivity behavior and temperature dependent of SPE. The 35% sodium acetate salt addition makes the supercapacitor's electrolyte have the highest ionic conductivity at room temperature, which is 5.57x10-4 S/cm.

With the development of the Internet, buying goods through online platforms too has increased leading to excessive buying patterns irrespective of the actual need for goods and services. With increased stress levels, work life pressure and many other factors, people tend to buy goods excessively from physical as well as online platforms. A number of scholars have examined the factors affecting this compulsive buying behaviour. Further, many researchers have investigated the impact of hedonic shopping motives towards compulsive buying behaviour. However, there is a dearth of literature in the South Asian context in relation to online compulsive purchase patterns. The current study focuses on examining the impact of hedonic shopping motives towards online compulsive buying behaviour of fashion clothing shoppers in Sri Lanka. The hedonic shopping motives include adventure seeking motive, gratification seeking motive, idea shopping, role shopping, value shopping and social shopping motives. The survey was conducted among 384 online fashion clothing shoppers in Sri Lanka to validate the proposed model empirically. The findings of the study provide evidence of the impact of hedonic shopping motives towards online compulsive buying behaviour among fashion clothing shoppers in Sri Lanka and ultimately provide a better understanding of the motives affecting online compulsive buying behaviour.

Impact of Personal Traits and Government Incentives on the Intention of Rooftop Solar Photovoltaic Installation in Sri Lanka
Authors: Ganeshwaran R.
Published: January 2024

Sri Lanka, as a developing country, faces a significant obstacle of energy shortage due to efforts in economic development and enhancement of the living conditions of the citizens. However, the country accounts for a comparatively low carbon footprint, which at present is slowly increasing due to the development of the country and increasing power demand, as the country has taken desperate measures like burning fossil fuels to meet the rising demand. The country now intends to find more sustainable and environment-friendly measures to meet the demand. The introduction of renewable energy has made an effort to change the way that energy is produced. A non-depleting and renewable source of power, renewable energy is also referred to as green energy. It's common to refer to environmentally friendly energy sources as "green products" (in this case, "energy"). Fossil fuels are currently being replaced with renewable energy sources. Solar has been identified as the most promising renewable energy source, yet the land shortage has made the choice questionable. However, considering these issues and the country’s economic condition, the implementation of smaller-scale rooftop solar photovoltaic panels for individual houses may be the best solution. The research purpose of this study is to investigate and understand the impact of personnel traits and government incentives on the intention of rooftop solar photovoltaic (PV) installation in Sri Lanka. The data for the study was gathered using 401 questionnaires dispersed around the country. The questionnaire was self-administered. The IBM SPSS Statistics 23 software was used to analyze the data that had been gathered. The findings demonstrate that consumer innovation, ecological lifestyle, environmental concern, and government incentives have a favorable influence on the public's propensity to install rooftop solar panels. In order to determine the influence of these elements on customers' installation intentions, this research examines the consumer perception theory-based model based on planned behavior theory. Local legislators, solar industry executives, and other stakeholders may greatly benefit from the study's findings.
