Published: September 2024

Bioresorbable stents (BRSs) offer significant advantages in treating congenital heart disease-related vascular stenoses, especially for pediatric patients. However, the insufficient mechanical performance of polymeric BRSs remains a critical challenge. In this study, Poly(p-dioxanone) (PPDO) was incorporated with graphene oxide (GO) for the first time to improve both mechanical properties and biocompatibility. PPDO/GO composites with varying GO contents were fabricated via solution mixing and solvent casting, and tensile tests revealed that lower GO content levels (0.2% and 0.5%) significantly improved the Young’s modulus, tensile strength, and elongation at break of PPDO due to hydrogen bonding and increased degree of crystallinity. 3D-printed PPDO/GO sliding-lock stents with optimal GO contents were fabricated by fused deposition modeling and demonstrated superior compression force compared to pristine PPDO stents. In vitro hemocompatibility and cytocompatibility assessments showed that 3D-printed PPDO/GO stents exhibited low hemolysis rate, reduced platelet adhesion, and enhanced adhesion and proliferation of endothelial cells. In vivo evaluation further demonstrated improved endothelialization in rat abdominal aortas implanted with 3D-printed PPDO/GO filaments for 4 weeks. Overall, PPDO/0.5%GO exhibited superior performance in compression force, hemocompatibility, cytocompatibility, and in vivo endothelialization. This study, for the first time, combines PPDO with GO and explains the mechanism of the enhanced mechanical properties of PPDO/GO composite material. Using 3D printing, PPDO/GO BRS with improved compression performance and biocompatibility were developed, highlighting its potential value for treating pediatric patients with CHD-related vascular stenoses.

One of the significant challenges in integrated optical systems is achieving miniaturization. Traditional components can limit the effective utilization of chip area. Devices with distinctive thickness and length characteristics, including the Mach Zehnder interferometer (MZI), the directional coupler, and waveguides, contribute to this issue, limiting the efficient use of chip area. Photonic crystals offer a solution to this problem. The proposed design results in two optical bandgap ranges, from 0.456586 to 0.675819 μm–1 and from 1.12855 to 1.16338 μm–1, both in TE mode with gap widths of 0.219233 and 0.34826 μm–1, respectively. The corresponding wavelength ranges are from 1479 to 2190 nm and 859 to 886 nm. The analysis of field propagation in the photonic crystal ring resonator (PCRR) is carried out using the finite-difference time domain (FDTD) method, while the bandgap analysis is performed by the plane wave expansion (PWE) method. This work primarily focuses on the incorporation of corner scatters in the PCRR. Corner scatters play a crucial role in guiding the field smoothly inside the ring, thus preventing the localization of light within the structure. After the simulation, various attributes were compared for both structures. At a resonant wavelength of 1550 nm, the input intensity is measured as 0.0591 a.u., and the output intensities for with and without corner scatter are 0.0458 and 0.0539 a.u., respectively.
Subjective measurement of resolution of image intensifier tubes
Authors: Chrzanowski Krzysztof
Published: September 2024

Limiting resolution is traditionally defined as a spatial frequency of smallest resolvable element of a resolution target that can be distinguish by a human observer. This definition and measurement method have been criticized in a series of literature sources due to its subjectivity and low repeatability/accuracy. Such criticism looks reasonable as it is commonly known that results of measurement of resolution of the same tubes carried out by several test teams can differ significantly. This paper presents a detail analysis of classical subjective measurement method of limiting resolution of image intensifier tubes implemented by real test systems. The findings show that in spite of a common opinion, subjectivity of measurement is not the main reason for differences of test results carried out by different test teams. The main reasons are differences in performance of optics of test systems, use of resolution targets of different types and polarity, and inherent spatial non-uniformity of performance of image intensifier tubes. The paper also shows that due to spatial non-uniformity it is very difficult to design automatic test systems that could produce the same results as human observers using classical subjective measurement method.

Published: September 2024

To improve the model training efficiency and the classification performance of the phase-sensitive optical time-domain reflectometer (Φ-OTDR) in disturbance events recognition, a preprocessing method based on Markov transition fields (MTF) and auto-encoder (AE) is proposed. The phase time series, derived from demodulation of the original scattering signals, are converted into images by using the MTF method. Subsequently, an auto-encoder is introduced to perform a dimensionality reduction characterization of the MTF images, and the outputs of the encoder will be used as features for classification. The experimental results demonstrate that, compared with directly processing time series using 1-D CNN and classifying MTF images using CNN, the features obtained by the proposed method can accelerate the training process and improve the recognition performance of the classification model. The recognition accuracy for the four classes of events on the fence reaches 95.6%, representing a 12% increase.
The Impact of Using Interactive Chatbots on Self-Directed Learning
Authors: Behforouz Behnam , Al Ghaithi Ali
Published: September 2024

The present study aimed to develop and implement an interactive chatbot in a language-learning setting. For this purpose, fifty Omani EFL students were divided into two equal groups: control and experimental. All the pretests were validated and piloted before the treatment to ensure practicality. The chatbot was designed using the WhatsApp platform, and instructions were given to the students. Some researcher-made tests, such as writing tasks, grammar, and reading comprehension activities, were assigned to both groups. In addition, an adapted questionnaire initially developed by Williamson (2007) was used as the pretest and posttest. The control group received all the materials using the traditional face-to-face teaching method, while the experimental group received all the instructions, explanations, and tests through the chatbot. The findings of the study revealed that the control group did not show any interest in completing the activities; on the contrary, the majority of participants in the experimental group engaged themselves in task achievements. Moreover, the self-directed learning questionnaire results showed that the experimental group progressed significantly from the pretest to the posttest in self-directed abilities, including awareness, learning strategies, activities, evaluation and interpersonal skills, with a statistically significant difference compared to the control group. The results of this study could be helpful for educators, students, and self-access centre staff.

Authors: Rahman Faizal Riza , Prabowo Janitra
Published: September 2024

This study aims to analyze the impact of financial distress on earnings management within companies listed on the Indonesia Stock Exchange (IDX) from 2019 to 2021. Utilizing a purposive sampling technique, the research focuses on 44 companies that are noted for their special status on the IDX. Key control variables examined include company size, leverage, cash flow operations (CFO), growth, profitability ratios (ROA), equity issuance (EISSUE), and debt issuance (DISSUE). The findings reveal that financial distress significantly and negatively influences earnings management, indicating that distressed companies are less likely to engage in manipulative financial reporting. Furthermore, the study identifies that all control variables contribute to a nuanced relationship between financial distress and earnings management. Specifically, variables such as size, CFO, leverage, ROA, EISSUE, and DISSUE exhibit a significant positive impact on earnings management, suggesting that larger companies with higher leverage and profitability are more prone to earnings manipulation. Conversely, the growth variable demonstrates a significant negative effect, implying that companies experiencing growth are less likely to manage earnings. These insights contribute to a deeper understanding of the dynamics between financial distress and corporate financial behavior, offering valuable implications for investors, regulators, and policymakers.
Aplicabilidade da mediação como método de solução de conflitos no âmbito administrativo disciplinar no Tribunal de Contas do Estado de Santa Catarina
Authors: Alves Elizete Lanzoni , Cardoso Geovane Eziel , Leal dos Santos Júlia Maria
Published: September 2024

Este artigo tem como finalidade demonstrar que a adoção da mediação como método de solução de conflitos no âmbito da administração pública, nos casos que a comporte, é meio hábil e adequado sem que haja a necessidade de instauração de processo administrativo disciplinar, tendo em vista vantagens significativas tanto do ponto processual quanto do temporal e econômico. Em geral, as controvérsias no âmbito administrativo surgem por ausência de diálogo e de estratégias para lidar com as divergências, sobretudo, em um meio em que a hierarquia e as atribuições têm fortes delimitações, traços fortes do Direito Administrativo Sancionador. Com foco específico no Tribunal de Contas do Estado de Santa Catarina, o estudo apresenta uma proposta que se fundamenta na constitucionalidade da utilização da mediação no processo administrativo disciplinar em virtude da ausência de legislação infraconstitucional específica. Sendo a mediação, nesse sentido, o melhor caminho quando se trata em solucionar conflitos de desentendimentos entre servidores públicos, valendo-se dos princípios fundamentais que regem o direito constitucional e administrativo. Para tanto, inicia-se sintetizando a evolução da relação Estado-sociedade, destacando a transição do Estado Absolutista para o Social e a deste para o Democrático de Direito, com ênfase no contexto pós-Constituição de 1988 no Brasil. Aborda desafios na aplicação do Estado gerencial, particularmente nos poderes hierárquico e disciplinar, o que resulta em procedimentos administrativos burocráticos. Como medida resolutiva, propõe a adoção de abordagens inovadoras, como a comunicação dialógica e orientativa por meio da mediação, visando resolver conflitos e evitar procedimentos disciplinares morosos e dispendiosos.

People make mistakes: Obtaining accurate ground truth from continuous annotations of subjective constructs
Authors: Booth Brandon M. , Narayanan Shrikanth S.
Published: September 2024

Accurately representing changes in mental states over time is crucial for understanding their complex dynamics. However, there is little methodological research on the validity and reliability of human-produced continuous-time annotation of these states. We present a psychometric perspective on valid and reliable construct assessment, examine the robustness of interval-scale (e.g., values between zero and one) continuous-time annotation, and identify three major threats to validity and reliability in current approaches. We then propose a novel ground truth generation pipeline that combines emerging techniques for improving validity and robustness. We demonstrate its effectiveness in a case study involving crowd-sourced annotation of perceived violence in movies, where our pipeline achieves a .95 Spearman correlation in summarized ratings compared to a .15 baseline. These results suggest that highly accurate ground truth signals can be produced from continuous annotations using additional comparative annotation (e.g., a versus b) to correct structured errors, highlighting the need for a paradigm shift in robust construct measurement over time.

Published: September 2024

This research examines the relationship between leverage, profitability, and carbon disclosure in the Indonesia Stock Exchange (IDX) energy industry from 2019 to 2022. As a moderator, this study also examines how profit growth affects the relationship between the three variables. Panel data multiple linear regression analysis served as the method of hypothesis testing. This study analyzes data on energy sector businesses listed on the Indonesia Stock Exchange during 2019–2022, totaling 84 observation periods. The results showed how profitability and leverage significantly negatively impacted carbon disclosure. Profit growth highlights how negatively profitability affects carbon disclosure. However, the relationship between leverage and carbon emission disclosure remains despite revenue increases. The findings provide important insights into the disclosure practices of the energy sector concerning carbon emissions and their impact on environmental sustainability. Based on the study's findings, businesses and pertinent parties should be able to develop policies that support the transition to a more sustainable energy industry.

Authors: Ariani Ade , Sugi Andi Neneng , Saparudin Muhammad , Valdiansyah Riyan Harbi
Published: September 2024

This study intends to determine the influence of audit opinion and firm size on audit delays with audit rotation as a mediating variable. We examined 30 firms listed in IDX Circular Letter 2020-2022 using purposive selection and secondary data from financial reports. Despite deadline extensions, these companies consistently needed to submit timely reports. The findings reveal that an unfavorable audit opinion negatively affects the rotation process, whereas a larger firm size has a positive effect. Additionally, audit opinions and rotation negatively affect audit delays, whereas company size has a positive influence. The study also shows that audit rotation partially mediates the association between audit opinion and audit delay and between firm size and audit delay. The research team acknowledges that prevailing economic conditions during data collection may affect the applicability of the results to other periods. This study implies that auditors and accountants identify the primary causes of audit delays, such as inadequate documentation, transaction complexity, and communication issues. Implementing best practices can improve financial reporting quality, reduce errors, and enhance auditor timeliness. Auditors and accountants are advised to adopt these practices to minimize audit delays.

El uso de Internet se ha vuelto esencial en la vida diaria, facilitando la educación, comunicación y el acceso a información. Las redes sociales, son utilizadas por el 60% de la población global, destacando el YouTube, Facebook, TikTok, Instagram y WhatsApp. En India, el 96.1% de los estudiantes de pregrado usa redes sociales cuando están aburridos y el 86.4% cuando se sienten solos. Por ello, el propósito de la investigación fue determinar si la adicción a redes sociales predice la soledad en universitarios de la selva peruana. Se analizaron 423 datos de estudiantes universitarios, varones y mujeres, entre 18 y 29 años (M= 21.943; DS= 2.566). La ARS se evaluó mediante la Escala Breve de Adicción a las Redes Sociales (CARS-R) y la variable soledad mediante la Escala de soledad de Jhon Gierveld. En cuanto a los resultados se evidenció que la ARS predice la soledad (R2 ajustado= 0.288, p < ,000). Es así que se concluye que un uso adictivo de las redes sociales predice sentimientos de soledad en universitarios de la selva peruana, por lo tanto, se recomienda realizar acciones que ayuden a mitigar esta adicción, pues la soledad está asociada a sentimientos de tristeza e ideación suicida.

In recent years, intensive studies with or without the use of sex pheromones and sex attractants have significantly increased our knowledge on the Zygaenidae (Lepidoptera) fauna of Türkiye (Turkey). An application of sex attractants from the series ‘EFETOV-2’ (a patented name) synthesised at the Crimean Federal University has allowed us to detect some species hitherto unknown in Türkiye (for example Rhagades pruni ([Denis & Schiffermüller], 1775) and Jordanita globulariae (Hübner, 1793)) and clarify many distributions. In this work we present new data on the results of testing the attractant EFETOV-2 (a racemic mixture of (2R)-butan-2-yl dodec-2-enoate and (2S)-butan-2-yl dodec-2-enoate) in some regions of Southeastern Anatolia of Türkiye. Determination of Zygaenidae species and their distribution ranges was carried out in Batman, Diyarbakır and Mardin Provinces in 2022–2024. Two Procridinae species, viz. Adscita obscura (Zeller, 1847) (31 males) and Jordanita anatolica (Naufock, 1929) (142 males), were attracted to the lures EFETOV-2 in all studied provinces.

Constraints on the Gas-phase C/O Ratio of DR Tau's Outer Disk from CS, SO, and C2H Observations

Published: September 2024

Millimeter wavelength observations of Class II protoplanetary disks often display strong emission from hydrocarbons and high CS/SO values, providing evidence that the gas-phase C/O ratio commonly exceeds 1 in their outer regions. We present new NOEMA observations of CS 5–4, SO 76–65 and 56–45, C2H N = 3–2, HCN 3–2, HCO+ 3–2, and H13CO+ 3–2 in the DR Tau protoplanetary disk at a resolution of ∼0.″4 (80 au). Estimates for the disk-averaged CS/SO ratio range from ∼0.4 to 0.5, the lowest value reported thus far for a T Tauri disk. At a projected separation of ∼180 au northeast of the star, the SO moment maps exhibit a clump that has no counterpart in the other lines, and the CS/SO value decreases to <0.2 at its location. Thermochemical models calculated with DALI indicate that DR Tau’s low CS/SO ratio and faint C2H emission can be explained by a gas-phase C/O ratio that is <1 at the disk radii traced by NOEMA. Comparisons of DR Tau’s SO emission to maps of extended structures traced by 13CO suggest that late infall may contribute to driving down the gas-phase C/O ratio of its disk.
Angular Momentum Loss during Stable Mass Transfer onto a Compact Object: The Effect of Mass Loss via Accretion Disk Winds
Authors: Gallegos-Garcia Monica , Jacquemin-Ide Jonatan , Kalogera Vicky
Published: September 2024

We use an analytic framework to calculate the evolution of binary orbits under a physically motivated model that accounts for angular momentum loss associated with winds from an accretion disk around the compact-objected accretor. Our prescription considers wind mass ejection from the surface of an accretion disk, accounting for a radial mass-loss dependence across the disk surface. We compare this to the standard prescription of angular momentum loss associated with isotropic mass loss from the vicinity of the accretor. The angular momentum loss from a disk wind is always larger. For mass ratios, q, between 2 and 10, angular momentum loss via a disk wind can be ≃3–40 times greater than the standard prescription. For the majority of mass ratios and disk properties, accounting for the disk wind can result in considerably smaller orbital separations compared to the standard formalism, the differences being ≃60% depending on how long the effect is integrated for. We conclude that it is important to consider the effects of angular momentum loss from a disk wind when evolving binary orbits.
The Challenge of Detecting Remote Spectroscopic Signatures from Radionuclides

Published: September 2024

The characterization of exoplanetary atmospheres through transit spectra is becoming increasingly feasible, and technology for direct detection remains ongoing. The possibility of detecting spectral features could enable quantitative constraints on atmospheric composition or even serve as a potential biosignature, with the sensitivity of the instrument and observation time as key limiting factors. This paper discusses the possibility that future remote observations could detect the presence of radioactive elements in the atmospheres of exoplanets. Such radionuclides could arise from cosmogenic or geologic sources, as well as from industrial sources, all of which occur on Earth. The detection of radionuclides in an exoplanetary atmosphere could reveal important properties about the planet’s geology or space environment and potentially could serve as a technosignature. However, many radionuclides, including those from industrial sources, attach to aerosol or other particles that cannot be remotely characterized. Limited experimental and theoretical spectral data exist for long-lived radionuclides, but the sensitivity required to detect the spectral features of some known radionuclides would be at least several orders of magnitude greater than required to detect the spectral features of molecular oxygen. Present-day remote spectroscopic observing mission concepts at ultraviolet to mid-infrared wavelengths are not sensitive to discern the presence of radionuclides in exoplanetary atmospheres. Interplanetary fly-by or probe missions may be more likely to provide such data in the future.
The Independence of Magnetic Turbulent Power Spectra to the Presence of Switchbacks in the Inner Heliosphere

An outstanding gap in our knowledge of the solar wind is the relationship between switchbacks and solar wind turbulence. Switchbacks are large fluctuations, even reversals, of the background magnetic field embedded in the solar wind flow. It has been proposed that switchbacks may form as a product of turbulence and decay via coupling with the turbulent cascade. In this work, we examine how properties of solar wind magnetic field turbulence vary in the presence or absence of switchbacks. Specifically, we use in situ particle and fields measurements from Parker Solar Probe to measure magnetic field turbulent wave power, separately in the inertial and kinetic ranges, as a function of switchback magnetic deflection angle. We demonstrate that the angle between the background magnetic field and the solar wind velocity in the spacecraft frame (θ

vB
) strongly determines whether Parker Solar Probe samples wave power parallel or perpendicular to the background magnetic field. Further, we show that θ

vB
is strongly modulated by the switchback magnetic deflection angle. In this analysis, we demonstrate that switchback deflection angle does not correspond to any significant increase in wave power in either the inertial range or at kinetic scales. This result implies that switchbacks do not strongly couple to the turbulent cascade in the inertial or kinetic ranges via turbulent wave–particle interactions. Therefore, we do not expect switchbacks to contribute significantly to solar wind heating through this type of energy conversion pathway although contributions via other mechanisms, such as magnetic reconnection, may still be significant.

Neutral sodium (Na i) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine both the time-averaged and time-series alkali spectral flux individually, over 4 nights at a hot Saturn system on a ∼2.8 day orbit about a Sun-like star WASP-49 A. Very Large Telescope/ESPRESSO observations are analyzed, providing new constraints. We recover the previously confirmed residual sodium flux uniquely when averaged, whereas night-to-night Na i varies by more than an order of magnitude. On HARPS/3.6 m Epoch II, we report a Doppler redshift at v
Γ,NaD = + 9.7 ± 1.6 km s−1 with respect to the planet’s rest frame. Upon examining the lightcurves, we confirm night-to-night variability, on the order of ∼1%–4% in NaD, rarely coinciding with exoplanet transit, not readily explained by stellar activity, starspots, tellurics, or the interstellar medium. Coincident with the ∼+10 km s−1 Doppler redshift, we detect a transient sodium absorption event dF
NaD/F
⋆ = 3.6% ± 1% at a relative difference of ΔF
NaD(t) ∼ 4.4% ± 1%, lasting Δt
NaD ≳ 40 minutes. Since exoplanetary alkali signatures are blueshifted due to the natural vector of radiation pressure, estimated here at roughly ∼−5.7 km s−1, the radial velocity is rather at +15.4 km s−1, far larger than any known exoplanet system. Given that the redshift magnitude v
Γ is in between the Roche limit and dynamically stable satellite orbits, the transient sodium may be a putative indication of a natural satellite orbiting WASP-49 A b.
For a Political Economy of Central Bank Digital Currency
Authors: Pfister Christian
Published: September 2024

Cet article propose de considérer la monnaie numérique de banque centrale (MNBC) d’un point de vue d’économie politique. À cet égard, les incitations en jeu suggèrent que la MNBC serait appréciée de certains agents, en particulier les décideurs de politique économique, et peu goûtée par d’autres, spécialement les banques. En outre, des considérations d’économie politique, davantage que d’analyse économique, pourraient jouer un rôle important dans la décision de lancer une MNBC de détail. Enfin, la MNBC de détail pourrait se voir accorder un clair avantage en termes de statut et de frais de transaction. une MNBC de détail programmable ouvrirait des perspectives de surveillance de masse dans les pays non-démocratiques et, d’une point de vue international, la MNBC semblerait bien adaptée à une militarisation.

Diplomatie numérique et stratégie d’influence politique
Authors: Nocetti Julien , Lyubareva Inna
Published: September 2024

Les technologies numériques ont profondément remodelé les pratiques diplomatiques en impliquant un nombre croissant d’acteurs au-delà des cadres étatiques, amplifiant ainsi le débat politique et renforçant l’influence des acteurs non traditionnels. L’influence, pivot de la diplomatie numérique, structure désormais les relations internationales, particulièrement dans le domaine de l’information. Depuis la deuxième décennie du XXI e siècle, deux tendances convergent : le déclin des prérogatives souveraines des États et l’affaiblissement des démocraties face aux régimes autoritaires, remettant en question, la centralité du numérique dans les relations diplomatiques et les stratégies d’influence. La « diplomatie numérique » s’est affirmée comme un concept essentiel, intégrant l’utilisation des technologies numériques pour la communication, l’engagement public, l’analyse des big data, ainsi que la gestion des crises en temps réel, la surveillance et l’influence des opinions publiques mondiales, et la coordination des réponses diplomatiques. La notion de « souveraineté numérique », où les États protègent leurs données nationales et gèrent leurs écosystèmes numériques, souligne l’importance croissante des enjeux technologiques dans la diplomatie contemporaine. Face à ces évolutions, chercheurs et diplomates doivent accorder une attention accrue pour adapter leurs pratiques.

Des premières caméras à l’expérimentation des algorithmes : un panorama du développement territorial, technologique et de l’encadrement juridique de la vidéosurveillance
Authors: Chatellier Régis
Published: September 2024

L’usage de la vidéo à des fins de sécurité publique n’a eu de cesse de se déployer dans le monde, et en France, depuis les années 1980, suivant plusieurs logiques et dynamiques : par un étalement territorial, depuis les métropoles vers les territoires ruraux ; par à-coups, à la faveur de pics événementiels, notamment les Jeux olympiques ; par opportunités technologiques, et de nouvelles formes de captation (reconnaissance faciale, vidéo algorithmique, drones) ; par des dynamiques sociales, lorsqu’elle est prise en charge par les citoyens (sonnettes connectées, surveillance participative). En France, alors que l’encadrement juridique s’est construit conjointement, peu de véritables évaluations ont été mises en œuvre.
Des deux primes réceptions françaises de l’œuvre d’Hannah Arendt : articulations paradoxales et/ou cohérentes ?
Authors: Roelens Camille
Published: September 2024

Dans cet article de philosophie politique de l’éducation et d’histoire contemporaine des idées politiques et éducatives, nous nous intéressons aux deux phases successives par lesquelles Arendt est devenue, dans l’espace intellectuel français, d’abord une théoricienne majeure du totalitarisme, ensuite une référence classique en philosophie de l’éducation. Nous montrons en particulier comment son articulation d’un antitotalitarisme politique résolu et d’un non moins solide conservatisme éducatif fit école, et est aujourd’hui à la source de certaines de nos difficultés à penser positivement une éducation démocratique compatible avec la société hypermoderne des individus et non, de manière plus négative, une éducation non totalitaire qui peut ne pas être exempte de rémanences aristocratiques (au sens que Tocqueville donne à ce terme) problématiques.
