Authors: Khalid Ika Liana , Abdullah Mohd Nor Syahrir , Mohd Fadzil Hidayah
Published: September 2024

The fourth industrial revolution's transformative trajectory of education highlights the critical role of Science, Technology, Engineering, and Mathematics (STEM), a meta-discipline characterized by active, problem-centric approaches like game-based learning, which is critical in navigating the transformations induced by the convergence of advanced technologies. However, the integration of Information and Communication Technology (ICT) has encountered substantial challenges in developing countries, with debates surrounding its potential to diminish hands-on learning experiences and pragmatic engagement in educational settings. Given the growing significance of digital educational content, this study undertakes a systematic review to examine the usefulness and implementation of digital learning in STEM education. The primary issue being researched is determining digital interventions' best integration and impact in improving STEM learning experiences and results. A thorough examination of various research, concentrating on various educational levels and digital technologies, was carried out to get significant insights into their pedagogical implications and efficacy. This paper employs the PRISMA approach to collect primary data using keywords such as "digital learning," "technology learning," and "STEM education." An advanced search on SCOPUS and Web of Science yielded 27 articles, revealing three central themes: (1) digital integration and innovation in STEM Education, (2) barriers, perceptions, and motivation in STEM learning, and (3) interdisciplinary and cross-cultural approaches in STEM education. The anticipated findings will provide a more nuanced understanding of digital learning's multifaceted effects on student engagement, academic performance, and interest in STEM subjects and highlight the transformative potential of digital tools in fostering innovative and inclusive learning environments. Finally, this study aims to provide significant insights into the techniques for effective integration of digital technologies in STEM, enhancing learning experiences and supporting the development of critical 21st-century skills and competencies.

Authors: Widjanarko Dwi , Kusumaningtyas Ratna Dewi , Roziqin Ahmad , Daniel Daniel
Published: September 2024

Biodiesel is one of the alternative fuels that can be used in diesel engines instead of diesel oil. Transesterification is used to create biodiesel from cooking oil. The stirring procedure in the reactor is one of the elements influencing the transesterification process. The purpose of this research is to investigate the influence of the number of stirrers in the transesterification reactor on biodiesel and diesel engine performance. This study was carried out by converting cooking oil into biodiesel via a transesterification process. Stirrers with one pair, two pairs, and three pairs of stirrer blades are employed in the stirring process in the transesterification reactor. The resulting biodiesel was tested for its properties before being used in a diesel engine to determine the performance of a diesel engine using transesterified biodiesel fuel. The resulting biodiesel is utilized as a diesel oil substitute at a ratio of 20% biodiesel to 80% diesel oil (B20). To determine diesel engine performance, the fuel mixture was tested on a diesel engine. The results demonstrated that the produced biodiesel met the Indonesian National Standard (SNI). Diesel engine performance demonstrates that there is no substantial change in the performance of diesel engines using Pertamina (Indonesian State Oil and Gas Mining) diesel fuel.

Authors: Hap Nguyen Van , Dam Mai Thanh , Khoi Nguyen Hoang , Phu Nguyen Minh
Published: September 2024

Co-generation of heat and electricity from solar cells is an energy efficient option because the photovoltaic (PV) efficiency is less than twenty percent, the rest goes to heat. In this paper, the heat emitted from the PV panel is used to produce hot air which is useful heat and to reduce the PV cell temperature thereby increasing the system performance. Independent parameters include air mass flow rate (), air channel height (H), PV panel aspect ratio (Ra), and environmental parameters (temperature, wind velocity, solar intensity) to investigate their influence on power and heat generation, and performances. The mathematical description of the system is formed using a lumped parameter model. The analytical results show that the overall performance is maximized at certain design parameters. This phenomenon is due to the trade-off between power generation, heat output, and fan power with a design specification. Optimizing the overall efficiency using a genetic algorithm (GA), which is a metaheuristic based on the principles of natural selection and categorized as part of the broader group of evolutionary algorithms, yields the maximum value of 98.76% at the optimal parameters = 0.3032 kg/s, H = 27.37 mm, and Ra = 1.809.
Coupling Computational Fluid Dynamics and Agent Based Modelling in Analysing the Progression of Stenosis in Blood Flow
Authors: Ismail Zuhaila , Yeou Jiann Lim
Published: September 2024

Coronary artery disease is one of the cardiovascular diseases caused by stenosis that forms in the artery due to fatty substances and cholesterol. This condition can lead to death. The development and progression of stenosis significantly depend on the blood flow within the artery. The present study aims to simulate the interaction between the progression of stenosis and blood flow using the Agent-Based Modelling (ABM) technique. ABM, widely utilized in social science and dynamical systems, is applied here to simulate this progression. COMSOL Multiphysics is used to compute the behaviour of blood flow in the artery. The essential data generated, such as wall shear stress, is then incorporated into the ABM to simulate the developmental progression of stenosis. The results reveal that ABM can effectively simulate the progression of stenosis due to blood flow. Additionally, changes in the geometry of the stenosis alter the characteristics of the blood flow passing through it. Understanding the interaction between blood flow and stenosis progression is crucial for developing advanced treatments for coronary artery disease.
Improve Analytical Solutions for Trapezoidal, Rectangular and Dovetail Shapes of Inclined Longitudinal Porous Fin
Authors: R.Khlefha Ahmed , Majeed  Jasim Abeer
Published: September 2024

This study improved the approximate analytical solutions of the heat distribution and transport of inclined longitudinal porous fin in the presence of radiative and convective environments with rectangular, trapezoidal, and dovetail profiles. The model of Darcy, which mimics the interaction of fluids and solids, is utilized to obtain the equation of governing the heat transfer of the porous fin. To investigate the rectangular, trapezoidal, and dovetail profiles, a single equation has been solved through analysis of the mathematical model by using the optimal differential transform method (ODTM) which consist least squares differential transform method (LSDTM), and the Galerkin differential transform method (GDTM) while the BVP4c presents the numerical solution. A comparison is made between the approximate analytical and numerical solutions for different parameters. It results in that the solutions produced from LSDTM and GDTM are closer to the numerical solution than the solutions of DTM, nonlinear autoregressive exogenous-levenberg marquardt algorithm (NARX-LMA) and cascade feedforward backpropagated-levenberg marquardt algorithm (CFB-LMA). A comprehensive graphic analysis was conducted to examine the effect of variation in inclination angles, tapering at the tip, wet porous parameters, internal heat generation, progressive natural convection parameters, and dimensionless radiation parameters on the thermal profile and thermal transfer rate of the porous longitudinal fin. The split fin design achieves the greatest heat transfer rate, trailed by rectangular and trapezoidal fin profiles, assuming that internal heat generation is maintained to a minimum.

Air pollution from industrialization and vehicle emissions is a serious hazard. This study assesses three native Indian plant species' resilience to pollution and adaptability for various environments by evaluating their Dust Carrying Capacity (DCC) and Air Pollution Tolerance Index (APTI). Four biochemical parameters— pH, ascorbic acid levels, chlorophyll, and relative water content—were examined in order to determine APTI. By comparing leaf area to dust deposition capacity, DCC was ascertained. The investigation was carried out at Mewar University utilizing conventional techniques for chemical analysis. The results indicate that, in line with the lower pollution levels at Mewar, Calotropis procera had the highest APTI value (13.71) and the lowest in Chanderiya (4.15). Nerium oleander and Polyalthia longifolia both followed a similar pattern. Because of its wider, hairy leaves, Calotropis procera had the maximum capacity (4.8) for dust capture at Mewar Campus. Comparable DCC values (3.8) were noted in Chanderiya (3.9) and beyond the campus, suggesting that it is environment- adaptable. At the Mewar Campus, Polyalthia longifolia displayed the highest DCC (1.8), whereas Nerium oleander consistently displayed lower DCC (0.8) everywhere it was found, most likely as a result of its smaller leaves. The significance of plant species in urban design and environmental management in contaminated areas is highlighted by these findings.

A Hyperparameters Tunned ML Algorithm for Fraud Identification in Banking and Financial Transactions
Authors: Rao Bogireddy Srinivasa , Murari Haritha
Published: September 2024

Banking, a pioneering industry, is experiencing rapid growth, leading to the adoption of cashless transactions. Digital banking offers better service quality but has faced challenges from fraudulent activities. Since the banking industry is expanding quickly throughout the globe, using cash for payments is becoming less common. Instead, people are using cashless transactions. Digital banking customers receive higher-quality services in money transfers, cashless payments, credit cards, and prepaid cards. Nonetheless, the fraudulent activities of scammers have drawn attention to the security of digital banking, as a lack of adequate protection has discouraged many users from using the service up to this point. Even though fraud is not a new problem, its associated actions always cause billions of dollars' worth of annual losses to the world economy. Fraudulent actions carry a wide range of severe financial hazards that might jeopardize an economy's profitability and reputation. The study aims to introduce an efficient hyperparameter-tuned machine learning approach to detect fraud in banking and financial transaction systems. Proper preprocessing and application of feature engineering, such as outlier rejection, null value handling, standardization, and parameter tuning, have been incorporated with the approach. Later, the Extreme gradient boosting model was trained with tunned parameters and evaluated with test data. The model demonstrated praiseworthy performance, having 99.63% accuracy. Extensive analysis using feature selection, confusion matrix, roc, and tunning evaluation graph was conducted to detect fraud in financial transactions.
A Comparative Simulation Study of Hot and Ultrahot Jupiter Atmospheres Using Different Ground-based High-resolution Spectrographs with Cross-correlation Spectroscopy
Authors: Dubey Dwaipayan , Majumdar Liton
Published: September 2024

In the era of state-of-the-art space-borne telescopes, high-resolution ground-based observation has emerged as a crucial method for characterizing exoplanets, providing essential insights into their atmospheric compositions. In the optical and near-infrared regions, high-resolution spectroscopy has been powerful for hot Jupiters (HJs) and ultrahot Jupiters (UHJs) during their primary transits, as it can probe molecules with better sensitivity. Here, we focus on a comparative simulation study of WASP-76 b (UHJ) and WASP-77 A b (HJ) for different numbers of transits, utilizing three ground-based spectrographs, GIANO-B (Telescopio Nazionale Galileo), CARMENES (Centro Astronomico Hispano Alemán), and ANDES (European Extremely Large Telescope or E-ELT), with varying instrumental parameters, spectral coverages, and resolutions. We aim to evaluate the feasibility of using the upcoming ground-based E-ELT to probe molecules from planet atmospheres and to show how it surpasses other ground-based observatories in terms of detectability. With the 1D model petitCODE, we have self-consistently simulated the atmospheric pressure–temperature profiles, which are subsequently integrated into the 1D chemical kinetics model, VULCAN, to evolve the atmospheric chemistry. High-resolution spectra are obtained by performing line-by-line radiative transfer using petitRADTRANS. Finally, we use the resulting spectra to assess the detectability (

Utilizing cross-correlation spectroscopy, we have successfully demonstrated the robust consistency between our simulation study and real-time observations for both planets.

Thermal Properties of Current Sheet Plasmas in Solar Flares
Authors: Gou Tingyu , Reeves Katharine K.
Published: September 2024

The current sheet is an essential feature in solar flares and is the primary site for magnetic reconnection and energy release. Imaging observations feature a long linear structure above the candle-flame-shaped flare loops, which resembles the standard flare model with the current sheet viewed edge-on. We investigate the thermal properties of plasmas surrounding the linear sheet during flares, using EUV observations from the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory. The differential emission measure analyses show evidence of high temperatures in the plasma sheets (PSs), containing hot emissions from only a narrow temperature range, suggestive of an isothermal feature. The sheet temperature remains constant at different heights above the flare arcade, peaking at around

log
T

= 7.0–7.1; while the well-studied 2017 September 10 X8.2 flare serves as an exception in that the temperature decreases with increasing height and peaks higher (

log
T

= 7.25) during the gradual phase. Most PS cases also hold similar emission measures and thicknesses; while the PS emissions drop exponentially above the flare arcade, the sheet thicknesses show no significant height association as for all the measurements. The characteristics of isothermal and steady temperature suggest balanced heating and cooling processes along the current sheet; in particular, additional heating may exist to compensate for the conductive and radiative cooling away from the reconnection site. Our results suggest a steady and uniform sheet structure in the macroscopic scale that results from flare reconnection.
The Contribution of Solar Magnetic Regions to the Residual Meridional and Zonal Flows
Authors: Braun D. C.
Published: September 2024

We estimate the contributions to the solar-cycle variation of solar meridional and zonal flows near the surface expected solely from local magnetic regions. Maps of flows near magnetic regions are obtained using helioseismic holography and averaged over ensembles of such regions with similar magnetic flux. These averaged flows are assigned to the positions and times of all magnetic regions identified from daily magnetograms over an 11 yr period. Residuals are obtained after averaging both meridional and zonal-flow components over longitude for each Carrington rotation and subtracting the temporal mean at each latitude. Results indicate that magnetic regions produce solar-cycle variations of both components in the active latitude range with peak amplitudes of about 1 m s−1, which represents only a fraction of the known variations in either the residual zonal or meridional flow with amplitudes around 3 and 5 m s−1, respectively. Thus it is unlikely that active regions, and compact magnetic concentrations in general, are the primary source of the 11 yr variation in these global flows. A threshold magnetic flux of 5 × 1020 Mx, below which no significant flows are observed, is identified as a check on the completeness of the set of magnetic regions. We also find that inflows around most magnetic regions are confined to within 10°–12° of their centers, in contrast with recent evidence of more extended inflows.
Inferring Host-galaxy Properties of LIGO–Virgo–KAGRA’s Black Holes
Authors: Vijaykumar Aditya , Fishbach Maya , Adhikari Susmita , Holz Daniel E.
Published: September 2024

Observations of gravitational waves from binary black hole (BBH) mergers have measured the redshift evolution of the BBH merger rate. The number density of galaxies in the Universe evolves differently with redshift based on their physical properties, such as their stellar masses and star formation rates. In this work we show that the measured population-level redshift distribution of BBHs sheds light on the properties of their probable host galaxies. We first assume that the hosts of BBHs can be described by a mixture model of galaxies weighted by stellar mass or star formation rate, and find that we can place upper limits on the fraction of mergers coming from a stellar-mass-weighted sample of galaxies. We then constrain the parameters of a physically motivated power-law delay-time distribution using GWTC-3 data, and self-consistently track galaxies in the UniverseMachine simulations with this delay-time model to infer the probable host galaxies of BBHs over a range of redshifts. We find that the inferred host galaxy distribution at redshift z = 0.21 has a median star formation rate ∼ 0.9 M
⊙ yr−1 and a median stellar mass of ∼1.9 × 1010
M
⊙. We also provide distributions for the mean stellar age, halo mass, halo radius, peculiar velocity, and large-scale bias associated with the host galaxies, as well as their absolute magnitudes in the B and Ks bands. Our results can be used to design optimal electromagnetic follow-up strategies for BBHs, and also to aid the measurement of cosmological parameters using the statistical dark-siren method.
The Response of Broadband Kilometric Radiation to Compressions of the Jovian Magnetosphere
Authors: Chen Yuening , Ye Shengyi , Yao Zhonghua , Zhang Binzheng
Published: September 2024

In the planetary magnetosphere, plasma waves act as the medium for particles to transfer energy. Jupiter is the largest planet in our solar system, and the giant magnetosphere is full of energetic particles, producing intense radio emissions. When interplanetary shocks in the solar wind interact with the Jovian magnetosphere, magnetospheric conditions change, and the characteristics of Jovian radio emissions show distinct variations accordingly. This study focuses on the morphological characteristics of Jovian broadband kilometric radiation (bKOM) under different magnetospheric conditions, i.e., relaxed and compressed. Using observations from Juno, both the frequency range and duration of Jovian bKOM radio emissions are studied, and we compare their variations during compressed and relaxed magnetospheric conditions. Our results show that under compressed magnetospheric conditions, the observed frequency range of Jovian bKOM generally exceeded 100 kHz, and their duration extended from 0 to 3 hr during uncompressed conditions to about 4–9 hr. The distinct features of radio emissions under different magnetospheric conditions imply that solar wind conditions have important influences on Jovian radio emissions, and thus the radio emissions can be used as a diagnostic tool of solar wind interaction with the Jovian magnetosphere.

Résumé Les principes du mouvement de la science ouverte se répandent dans les pratiques de diffusion des résultats de la recherche. En rendant accessibles et ouverts leurs résultats, les communautés de recherche permettraient à d’autres d’étayer leurs propos, leurs recherches via un accès non monétisé facilitant ainsi l’avancée des connaissances et leur libre circulation. Pourtant, l’actualité scientifique s’émaille régulièrement de méconduites scientifiques issues notamment de dérives d’une évaluation de la recherche reposant sur des critères quantitatifs. En observant l’écosystème de la recherche, notamment son New Public Management (NPM) et son accountability , notre texte rend compte des possibles effets correcteurs de l’ Open Scholarly communication selon quatre axes : l’ open peer review , la politique éditoriale des revues, la curation communautaire et les métriques alternatives.

Peut-on se passer de représentations en sciences cognitives ?
Authors: Munuera Jérôme
Published: September 2024

Regarder ou saisir un objet constituent, à première vue, des actes simples et triviaux. Néanmoins le contrôle de tels mouvements nécessite, entre autres, l’existence de processus de coordination complexes entre entrées sensorielles et sorties motrices, afin de compenser l’effet de la variabilité sensorimotrice inhérente à tout système moteur. Un concept clé décrit ces processus de contrôle : les modèles internes. Il s’agit de représentations dynamiques de l’état de nos appareils sensorimoteurs, inscrites au sein d’un réseau d’aires cérébrales. Ces représentations permettent la comparaison entre un mouvement désiré, reflété par une copie d’efférence représentant la commande motrice programmée initialement pour atteindre un but, et le mouvement réalisé (souvent variable) donné par les réafférences sensorielles proprioceptives et visuelles. Lorsqu’une différence est perçue suite à cette comparaison, un signal d’erreur motrice serait envoyé afin d’ajuster le mouvement en cours d’exécution. Ce chapitre souligne ainsi l’existence, au sein du système sensorimoteur, de processus de représentation de l’action permettant l’optimisation de nos mouvements.
L'empreinte des dirigeants
Authors: Strauss Wilfrid
Published: September 2024

Au travers d’une réflexion sur les fonctions du dirigeant hospitalier, Wilfrid Strauss considère deux figures du directeur. Selon la première, son rôle consiste à imaginer le futur, à concevoir de nouvelles perspectives et à porter ces changements. Il est alors un « visionnaire ». Une autre approche le dessine sous les traits du « médiateur ». Plus classique si l’on se réfère aux descriptions faites par les intéressés de leur propre métier, cette seconde approche tend à valoriser l’écoute, la construction d’un espace de délibération et la recherche de compromis entre des acteurs opposés. À partir d’une étude de cas très détaillée, décrite avec un grand soin et un souci constant de probité intellectuelle, Wilfrid Strauss montre que ces deux figures du dirigeant nécessitent d’être articulées. La vision est comme le souffle ou l’inspiration. Elle irrigue un changement et son absence conduit à des œuvres creuses. Mais, une vision, aussi inspirée soit-elle, ne se concrétise que par des compromis et des transactions entre des acteurs auprès desquels le directeur-médiateur vient jouer le rôle de tiers : le souffle et la glaise.
L'empreinte des dirigeants
Authors: Wernert Philippe
Published: September 2024

Dans cette analyse, Philippe Wernert part de son étonnement face au manque de rationalité des acteurs. Il interroge la décision, non pas à l’instant où le stylo rejoint la feuille pour sceller un avant et un après censés irréversibles, mais au travers du long processus émaillé de précipitations, d’hésitations et de revirements qui marquent la plupart des projets hospitaliers. Non seulement les acteurs adoptent la première solution « satisfaisante », mais ils s’y précipitent comme si l’incertitude d’une situation où de multiples possibles restent ouverts était anxiogène. Par la simplicité de son style, à partir de quatre exemples de projets, Philippe Wernert met à nu l’univers mental dans lequel bien des responsables hospitaliers se trouvent dans les changements organisationnels qu’ils conduisent.

L’intérêt supérieur de l’enfant – Un dialogue entre théorie et pratique
Authors: Tuite Margaret
Published: September 2024

Margaret Tuite s’intéresse à la notion d’intérêt supérieur de l’enfant dans les travaux de l’Union européenne. L’intérêt supérieur de l’enfant est inscrit dans plusieurs textes législatifs de l’Union, tels l’article 24 de la Charte des droits fondamentaux et le Règlement Bruxelles IIa de 2003, relatif aux conflits familiaux transfrontaliers. Un rapport sur l’application du Règlement Bruxelles IIa publié en 2014 a conclu qu’il fallait apporter des améliorations ciblées aux règles existantes. Une étude de l’Union visant à recueillir des données sur la participation des enfants aux procédures pénales, civiles et administratives a également entrepris de déterminer la façon dont les États membres de l’Union mettent en avant ou défendent l’intérêt supérieur de l’enfant en tant que principe, droit et règle de procédure. L’étude a mis au jour des différences entre les pays et a montré que les mesures visant à assurer la mise en œuvre effective du principe d’intérêt supérieur de l’enfant dans les procédures judiciaires sont plus développées dans le domaine des litiges familiaux et du placement d’enfants que dans d’autres domaines du droit. Certains pays n’appliquent pas de telles mesures dans le droit relatif à l’asile et à l’immigration, par exemple. Cette situation est extrêmement préoccupante car l’intérêt supérieur de l’enfant doit être une considération primordiale dans toutes les affaires qui le concernent.
L'imaginaire et l'intuition dans les sciences
Authors: Léna Pierre
Published: September 2024

Résumé. En astronomie, les interrogations sur l’univers ont été formulées dès la naissance de la science, il y a vingt-cinq siècles au moins en Occident comme en Orient. Les réponses proposées par l’imagination étaient largement de l’ordre du mythe, faute de possibilité de vérification, ou même de l’idée d’une vérification possible. Dans une science où l’expérimentation directe sur les corps célestes est impossible, l’observation joue un rôle déterminant. Celle-ci est conditionnée par les techniques disponibles, mais aussi par les questions qui peuvent être formulées, donc par les représentations et substrats théoriques disponibles. Ce jeu incessant entre connaissance objective du ciel et modèles de pensée a marqué, et marque toujours le développement de l’astronomie. Comment, dans ce contexte bien spécifique, les idées neuves surgissent-elles ? Sont-elles stimulées par des observations inattendues, devenues possibles grâce à un progrès technique et qui ne rentrent dans aucun des cadres conceptuels pré-existants ? Sont-elles au contraire le résultat de l’élaboration d’un concept théorique nouveau, qui va susciter l’observation, voire l’instrument, et se voir confirmé ? Chacune de ces situations est survenue tour à tour dans l’histoire, et chacune pourrait se voir illustrée de façon exemplaire. Nous développerons un exemple de concept instrumental remarquable, celui des trous d’ Young , dont la fortune en physique et la fécondité en astronomie depuis deux siècles n’ont d’égale que la simplicité extrême du concept. Analyser comment l’imagination et l’intuition ont pu être stimulées par ce concept est difficile, mais l’exposé tentera de proposer quelques pistes.
Mali - France

En tant que membre de la CEDEAO, le Mali est impliqué dans la négociation d’un accord de partenariat économique qui pourrait se traduire par la mise en place d’une zone de libre-échange avec l’Union européenne à partir de 2008. L’intégration régionale est au cœur de l’accord de Cotonou signé entre l’Union européenne et les ACP en 2000. Ce texte cherche à mettre l’accent, d’une part, sur l’importance des mesures d’accompagnement qui doivent être prises pour que l’APE soit véritablement un outil de développement et, d’autre part, sur le poids du contexte international à prendre en compte dans l’évaluation des effets. De plus, paradoxalement, alors que l’intégration régionale est au cœur de l’accord de Cotonou, la mise en place d’une zone de libre-échange nord-sud pourrait avoir des effets contradictoires sur les processus d’intégration sud-sud.

The property $ (\omega{ \pi }) $ as a generalization of the a-Weyl theorem
Authors: Xu Wei , Aponte Elvis , Vasanthakumar Ponraj

In this paper, for a bounded linear operator defined on a complex Banach space of infinite dimension, we consider the set of isolated points in its approximate point spectrum, which are eigenvalues of finite multiplicity; this set can be equal to the spectrum of the operator but without its upper semi-Fredholm spectrum, and this relation or equality defines in the literature a new spectral property called the property $ (\omega{ \pi }) $ and is a generalization of the classical a-Weyl theorem. We establish some characterizations and consequences about the property $ (\omega{ \pi }) $, some with topological aspects. Furthermore, we study this property through the Riesz functional calculus. Part of the spectral structure of a linear operator verifying property $ (\omega{ \pi }) $ is described, obtaining some associated properties.
Adaptive state observer event-triggered consensus control for multi-agent systems with actuator failures

An adaptive neural network event-triggered consensus control method incorporating a state observer was proposed for a class of uncertain nonlinear multi-agent systems (MASs) with actuator failures. To begin, a state observer was constructed in an adaptive backstepping framework to estimate the MASs' unmeasurable states, and a radial basis function neural network (RBFNN) was employed to approximate the unknown nonlinear function of MASs. Meanwhile, to reduce the impact of actuator failure on the performance of MASs, the adaptive event-triggered mechanism (ETM) was designed to dynamically compensate for actuator failures, which alleviated the communication burden among individual agents by decreasing the update frequency of the control signals. Furthermore, all followers can track the leader's output signal with the synchronization errors converging to zero. Finally, simulation examples were used to verify the effectiveness of the proposed control strategy.
Sustainability through People, Mindset, and Culture

Published: September 2024

In modern times, when short-term survival appears to be a granted thing for humans, our focus has been on making progress riding on waves of science, technology, and our never-ending quest for being better and superior. In this race, we are losing sight of the critical need for capabilities, means, and ends to be sustainable. In a global society, achieving inclusive and sustainable growth can be made possible by focusing on the key pillars of—people, culture, and mindset. People through their actions, the culture of sustainability by binding us together in this journey, and a mindset that brings fo-cus on keeping sustainability at the center of every thought, idea, and perspective that gets developed and brought into action, can directly impact sustainability. This paper attempts to examine the role that the suggested framework with dimensions—people, culture, and mindset can play in achieving inclusive and sustainable growth.
Beyond Mountains: Toward Liberatory Development
Authors: Mohan Brij
Published: September 2024

Areas of social development are manifestations of Social Reality (SR) which defines possibilities and barriers to achieving a better life. An argument is made to unravel the “dialectic” of a broken society in the post-imperialist world. At the heart of Liberatory Development, one must recognize the lethality of coloniality and its vestiges that incubate a culture of dehumanizing subjugation, urbicidal inequality, and global injustice. A Kaleidoscopic view of human misery and our failure to address fundamental issues signifies the call for needed praxis.

Monocytes and macrophages express the transcription factor MAFB (V-maf musculoaponeurotic fibrosarcoma oncogene homolog B) and protect against ischemic acute kidney injury (AKI). However, the mechanism through which MAFB alleviates AKI in macrophages remains unclear. In this study, we induced AKI in macrophage lineage-specific Mafb-deficient mice (C57BL/6J) using the ischemia-reperfusion injury model to analyze these mechanisms. Our results showed that MAFB regulates the expression of Alox15 (arachidonate 15-lipoxygenase) in macrophages during ischemic AKI. The expression of ALOX15 was significantly decreased at the mRNA and protein levels in macrophages that infiltrated the kidneys of macrophage-specific Mafb-deficient mice at 24 h after ischemia-reperfusion injury. ALOX15 promotes the resolution of inflammation under acute conditions by producing specialized proresolving mediators by oxidizing essential fatty acids. Therefore, MAFB in macrophages promotes the resolution of inflammation in ischemic AKI by regulating the expression of Alox15. Moreover, MAFB expression in macrophages is upregulated via the COX-2/PGE2/EP4 pathway in ischemic AKI. Our in vitro assay showed that MAFB regulates the expression of Alox15 under the COX-2/PGE2/EP4 pathway in macrophages. PGE2 mediates the lipid mediator (LM) class switch from inflammatory LMs to specialized proresolving mediators. Therefore, MAFB plays a key role in the PGE2-mediated LM class switch by regulating the expression of Alox15. Our study identified a previously unknown mechanism by which MAFB in macrophages alleviates ischemic AKI and provides new insights into regulating the LM class switch in acute inflammatory conditions.

Organizational factors determine patient satisfaction, since nursing care depends on organizations, in which the majority of actions involve nurses to provide holistic nursing care. Spirituality can be an important key, because patients feel all needs are fulfilled, making Sharia-Based Nursing Care (SBNC) a mediator of organizational factors for patient satisfaction. The aim of this paper is analyzing the role of organizational consolidation factors and SBNC model to determine patient satisfaction in Sharia hospitals. This analytical correlation study used a cross-sectional design and cluster sampling technique on 260 respondents as the samples, consisting of nurses and patients in patient rooms in X Islamic Hospital, Indonesia. The variables of this study, the organizational factors, SBNC, and patient satisfaction were collected using a questionnaire; all variables were assessed through the use of a questionnaire, and permission to modify or employ the instrument was obtained from the original authors, and analyzed using Smart Partial Least Squares (SmartPLS). Organizational factors have significant influence on SBNC (p-value=0.000; β-value=0.786; t-value>1.96), organizational factors have moderately significant influence on patient satisfaction (p-value=0.000; β-value=0.508; t-value>1.96), SBNC has significant influence on patient satisfaction (p-value=0.000; β-value=0.430; t-value>1.96), the consolidation of organizational factors with SBNC influences patient satisfaction (p-value=0.001; β-value=0.338; t-value>1.96). Nurses with good leadership, culture, and who give appropriate rewards can shape the quality of the profession by implementing SBNC; patients feel all needs are fulfilled, especially the spiritual aspect, and satisfaction with the nursing services.

Nurses who provide nursing care are urgently required to assess the patient’s spiritual needs so a correct nursing intervention can be given to the patient. Unfortunately, up to present, few instruments are available to specifically focus on patient’s spiritual needs. The aim of this study was to identify the perception of experience of nurses in providing spiritual nursing care to patients in cardiovascular wards as a foundation to develop a specific spiritual nursing care assessment tool. A sample of six nurses participated in this qualitative study. Data collection was conducted through in-depth interviews to nurses used thematic analysis. There were five themes identified: i) spiritual care meaning for nurses; ii) nurse’s current belief in providing spiritual care; iii) barriers in conducting spiritual nursing care; iv) expected solution to eliminate the barriers; v) efforts to improve spiritual nursing care. This study suggest to have a spritual care assessment instruments in order to make it easier for nurses to establish a spiritual nursing diagnosis, so that existing nursing care interventions can be carried out on target according to the client's priority problems.

Clinical placement in nursing education largely depends on the nursing student’s readiness to engage patient care. This review aims to illustrate the level of practice readiness in nursing students preparing for clinical placement, explore gender differences in practice readiness, identify the measurement tools used to assess readiness, and explore the various aspects of readiness measured. A systematic search was performed in the PubMed, SCOPUS, Ebsco, ProQues, ERIC, MEDLINE (EBSCOhost) databases.  Relevant studies focused on nursing students, practice readiness before or during the professional education phase, and publications from 2018-2023. From 634 records, and seven articles meet the inclusion criteria. The studies utilized three primary measurement tools: the Casey-Fink Readiness for Practice Survey, RIPLS, and custom instruments to assess practice readiness. Results indicated high readiness scores for professional responsibilities and communication skills, interprofessional education, and mixed readiness for clinical practice and treating COVID-19 patients. These findings highlight the diverse factors influencing nursing students' preparedness for clinical practice. The assessment of readiness for practice in nursing students has diverse aspects. Nursing educational institutions need to make efforts in developing learning strategies before students enter the clinical environment.
