Extended Stellar Populations in Ultrafaint Dwarf Galaxies
Authors: Tau Elisa A. , Vivas A. Katherina , Martínez-Vázquez Clara E.
Published: January 2024

The possible existence of stellar halos in low-mass galaxies is being intensely discussed nowadays after some recent discoveries of stars located in the outskirts of dwarf galaxies of the Local Group. RR Lyrae stars can be used to identify the extent of these structures, taking advantage of the minimization of foreground contamination they provide. In this work we use RR Lyrae stars obtained from Gaia DR3, the Dark Energy Survey, the Zwicky Transient Facility, and Pan-STARRS1 to explore the outskirts of 45 ultrafaint dwarf galaxies. We associate the stars with a host galaxy based on their angular separations, magnitudes, and proper motions. We find a total of 120 RR Lyrae stars that belong to 21 different galaxies in our sample. We report seven new RR Lyrae stars in six ultrafaint dwarf galaxies (Hydrus I, Ursa Major I, Ursa Major II, Grus II, Eridanus II, and Tucana II). We found a large number of new possible members in Bootes I and Bootes III as well, but some of them may actually belong to the nearby Sagittarius stream. Adding to our list of 120 RR Lyrae stars the observations of other ultrafaint dwarf galaxies that were beyond the reach of our search, we find that at least 10 of these galaxies have RR Lyrae stars located at distances greater than four times their respective half-light radius, which implies that at least 33% of the 30 ultrafaint dwarfs with a population of RR Lyrae stars have extended stellar populations.
Accuracy Analysis for Shack–Hartmann Wave Front Sensing with Extended Sources
Authors: Wei Xiya , Rao Changhui
Published: January 2024

Correlating the Shack–Hartmann wave front sensor (SH-WFS) with extended targets is widely used in solar adaptive optics systems. This paper aims to introduce a theoretical analysis that evaluates the accuracy of the SH-WFS on extended sources, with a specific focus on the implementation of the Normalized Cross-correlation (NCC) algorithm. To obtain an accurate error description, we utilized the calculation formula of the NCC algorithm to directly express the coordinates of the maximum value in the correlation function matrix. Furthermore, we determined the variance of the centroid position through the error transfer function, which quantifies the measurement error. In comparison with the previous findings of Michau et al., our result exhibits a coefficient disparity, specifically obtaining results 1.5 times higher than their work. The extensive solar granulation simulation and experimental results validate the theoretical error formulas. These error formulas can effectively estimate the accuracy of the SH-WFS, providing a theoretical foundation for the design of optical systems.

Determining how the galactic environment, especially the high gas densities and complex dynamics in bar-fed galaxy centers, alters the star formation efficiency (SFE) of molecular gas is critical to understanding galaxy evolution. However, these same physical or dynamical effects also alter the emissivity properties of CO, leading to variations in the CO-to-H2 conversion factor (α
CO) that impact the assessment of the gas column densities and thus of the SFE. To address such issues, we investigate the dependence of α
CO on the local CO velocity dispersion at 150 pc scales using a new set of dust-based α
CO measurements and propose a new α
CO prescription that accounts for CO emissivity variations across galaxies. Based on this prescription, we estimate the SFE in a sample of 65 galaxies from the PHANGS–Atacama Large Millimeter/submillimeter Array survey. We find increasing SFE toward high-surface-density regions like galaxy centers, while using a constant or metallicity-based α
CO results in a more homogeneous SFE throughout the centers and disks. Our prescription further reveals a mean molecular gas depletion time of 700 Myr in the centers of barred galaxies, which is overall three to four times shorter than in nonbarred galaxy centers or the disks. Across the galaxy disks, the depletion time is consistently around 2–3 Gyr, regardless of the choice of α
CO prescription. All together, our results suggest that the high level of star formation activity in barred centers is not simply due to an increased amount of molecular gas, but also to an enhanced SFE compared to nonbarred centers or disk regions.

Chromospheric differential rotation is a key component in comprehending the atmospheric coupling between the chromosphere and the photosphere at different phases of the solar cycle. In this study, we therefore utilize the newly calibrated multidecadal Ca ii K spectroheliograms (1907–2007) from the Kodaikanal Solar Observatory (KoSO) to investigate the differential rotation of the solar chromosphere using the technique of image cross-correlation. Our analysis yields the chromospheric differential rotation rate Ω(θ) = (14.61 ± 0.04–2.18 ± 0.37

day−1. These results suggest the chromospheric plages exhibit an equatorial rotation rate 1.59% faster than the photosphere when compared with the differential rotation rate measured using sunspots and also a smaller latitudinal gradient compared to the same. To compare our results to those from other observatories, we have applied our method on a small sample of Ca ii K data from Rome, Meudon, and Mount Wilson observatories, which support our findings from KoSO data. Additionally, we have not found any significant north–south asymmetry or any systematic variation in chromospheric differential rotation over the last century.
Effectiveness of Drug Therapy in Abortion on Medical Indications in Hospital Conditions
Authors: Zhekov Zhivko , Radeva Svetlana , Kovacev Emily
Published: January 2024

BACKGROUND: The model in the Specialized Hospital of Obstetrics and Gynecology in Varna is becoming more and more widespread. The medical abortion, as a means of choice for behavior in abortion on medical indications, in hospital conditions, after the opinion of the commission to a hospital institution with a profile of specialty gynecology, and in case of abortion on request in hospital or pre-hospital medical activity. In Europe, this model has been in place for 30 years, and clinical experience shows that complications and mortality are many times lower than with surgery.
MATERIALS AND METHODS: Conducted own survey for the period January 2021-July 2023 of 37 patients who went through a pregnancy termination committee on medical grounds.
RESULTS AND DISCUSSION: About 89.2% of cases have a positive opinion of the commission in the hospital structure. Patients with higher education had better outpatient follow-up (χ2 = 12,662, p = 0.002). The greatest effectiveness is the three-fold administration of a drug regimen between 6 and 12 h (χ2 = 74,000, p = 0.000) and the gestation period of 12–20 g.w. (χ2 = 38.858, p = 0.025), and single drug administration during pregnancy (8–13 g.w.) (χ2 = 30.537, p = 0.006) and effect up to the 6th h (χ2 = 8.133, p = 0.004).
CONCLUSION: The choice of a method of medical behavior is the result of a complex approach with regard to a number of factors related to pregnancy, general somatic status, and carried out diagnostic activities. An applied therapeutic approach reduces hospital costs, and the patient has a quick recovery period. Early and timely diagnosis and outpatient follow-up of patients in pre-hospital care are important informative values.

Faut-il à nouveau légiférer sur la santé mentale et la psychiatrie ?
Authors: Bauduret Jean François
Published: January 2024

Résumé L’auteur n’était pas persuadé initialement de la nécessité de faire une nouvelle loi, mais l’analyse de l’évolution des pratiques et les desiderata des personnes concernées appellent une loi qui devrait être une source d’inspiration pour les professionnels. Un retour sur le rapport Zambrowski, le livre blanc de la santé mentale ou le rapport de Michel Laforcade montrent que les rapports permettent des lois structurantes au niveau national. Il peut en aller de même avec le rapport Coldefy-Maugiron ou le rapport de la fondation Jean Jaurès présenté par le Dr Boris Nicolle. En s’appuyant sur ces textes, une nouvelle loi devrait permettre de redonner de l’attractivité et du sens aux actions conduites et la consécration de concepts structurants, de refonder l’organisation territoriale et de modifier la gouvernance de la santé mentale et de la psychiatrie. Sa préférence va à une loi interministérielle qui aurait des impacts sur l’ensemble des codes (et pas seulement sur le code de la santé).

Délimitation des diagrammes syntaxiques dans la grammaire scolaire
Authors: Gregov Nicolas
Published: January 2024

Dans cet article, nous proposons une réflexion sur la délimitation des diagrammes syntaxiques dans la grammaire scolaire. En faisant l’hypothèse d’une transposition didactique des diagrammes du savoir savant (les travaux en syntaxe) vers le savoir à enseigner (la grammaire scolaire), nous cherchons à identifier et catégoriser les diagrammes utilisés dans les ouvrages de grammaire scolaire. Face à certaines schématisations au statut incertain, situées entre la phrase et le diagramme prototypique, nous élaborons une grille d’analyse permettant d’évaluer la « diagrammaticité », soit le degré d’iconicité, de ces schématisations. Nous appliquons ensuite cette grille aux diagrammes présents dans trois grammaires scolaires récentes, la Grammaire Bescherelle (2006), le Petit Grevisse (2009) et la Phrase (2015). L’analyse met en évidence une diversité de pratiques diagrammatiques au sein de la grammaire scolaire, tout en soulignant l’influence des savoirs savants.
The Rishi Transform method for solving multi-high order fractional differential equations with constant coefficients
Authors: Turab Ali , Hilmi Hozan , Guirao Juan L.G. , Jalil Shabaz , Chorfi Nejmeddine , Mohammed Pshtiwan Othman
Published: January 2024

In this paper, we suggest the Rishi transform, which may be used to find the analytic (exact) solution to multi-high-order linear fractional differential equations, where the Riemann-Liouville and Caputo fractional derivatives are used. We first developed the Rishi transform of foundational mathematical functions for this purpose and then described the important characteristics of the Rishi transform, which may be applied to solve ordinary differential equations and fractional differential equations. Following that, we found an exact solution to a particular example of fractional differential equations. We looked at four numerical problems and solved them all step by step to demonstrate the value of the Rishi transform. The results show that the suggested novel transform, "Rishi Transform, " yields exact solutions to multi-higher-order fractional differential equations without doing complicated calculation work.
$ H_\infty $ deployment of nonlinear multi-agent systems with Markov switching topologies over a finite-time interval based on T–S fuzzy PDE control
Authors: Wei Hongbo , Cui Xuerong , Zhang Yucheng , Zhang Jingyao
Published: January 2024

The deployment of multi-agent systems (MASs) is widely used in the fields of unmanned agricultural machineries, unmanned aerial vehicles, intelligent transportation, etc. To make up for the defect that the existing PDE-based results are overly idealistic in terms of system models and control strategies, we study the PDE-based deployment of clustered nonlinear first-order and second-order MASs over a finite-time interval (FTI). By designing special communication protocols, the collective dynamics of numerous agents are modeled by simple fist-order and second-order PDEs. Two practical factors, external disturbance and Markov switching topology, are considered in this paper to better match actual situations. Besides, T–S fuzzy technology is used to approximate the unknown nonlinearity of MASs. Then, by using boundary control scheme with collocated measurements, two theorems are obtained to ensure the finite-time $ H_\infty $ deployment of first-order and second-order agents, respectively. Finally, numerical examples are provided to illustrate the effectiveness of the proposed approaches.
Laplacian spectrum of the unit graph associated to the ring of integers modulo $ pq $
Authors: Fakieh Wafaa , Alsaluli Amal , Alashwali Hanaa
Published: January 2024

Let $ R $ be a ring and $ U(R) $ be the set of unit elements of $ R $. The unit graph $ G(R) $ of $ R $ is the graph whose vertices are all the elements of $ R $, defining distinct vertices $ x $ and $ y $ to be adjacent if and only if $ x + y \in U(R) $. The Laplacian spectrum of $ G(\mathbb{Z}_n) $ was studied when $ n = p^{m} $, where $ p $ is a prime and $ m $ is a positive integer. Consequently, in this paper, we study the Laplacian spectrum of $ G(\mathbb{Z}_n) $, for $ n = p_1p_2...p_k $, where $ p_i $ are distinct primes and $ i = 1, 2, ..., k $.
An extension of Herstein's theorem on Banach algebra
Authors: Ansari Abu Zaid , Alrehaili Suad , Shujat Faiza
Published: January 2024

Let $ \mathcal{A} $ be a $ (p+q)! $-torsion free semiprime ring. We proved that if $ \mathcal{H}, \mathcal{D} : \mathcal{A}\to \mathcal{A} $ are two additive mappings fulfilling the algebraic identity $ 2\mathcal{H}(a^{p+q}) = \mathcal{H}(a^p) a^q+ a^p \mathcal{D}(a^q)+\mathcal{H}(a^q) a^p+ a^q \mathcal{D}(a^p) $ for all $ a\in \mathcal{A} $, then $ \mathcal{H} $ is a generalized derivation with $ \mathcal{D} $ as an associated derivation on $ \mathcal{A} $. In addition to that, it is also proved in this article that $ \mathcal{H}_1 $ is a generalized left derivation associated with a left derivation $ \delta $ on $ \mathcal{A} $ if they fulfilled the algebraic identity $ 2\mathcal{H}_1(a^{p+q}) = a^p \mathcal{H}_1(a^q)+ a^q \delta(a^p)+a^q \mathcal{H}_1(a^p)+ a^p \delta(a^q) $ for all $ a \in \mathcal{A} $. Further, the legitimacy of these hypotheses is eventually demonstrated by examples and at last, an application of Banach algebra is presented.
Dual uncertainty-guided multi-model pseudo-label learning for semi-supervised medical image segmentation
Authors: Qiu Zhanhong , Gan Weiyan , Yang Zhi , Zhou Ran , Gan Haitao
Published: January 2024

Semi-supervised medical image segmentation is currently a highly researched area. Pseudo-label learning is a traditional semi-supervised learning method aimed at acquiring additional knowledge by generating pseudo-labels for unlabeled data. However, this method relies on the quality of pseudo-labels and can lead to an unstable training process due to differences between samples. Additionally, directly generating pseudo-labels from the model itself accelerates noise accumulation, resulting in low-confidence pseudo-labels. To address these issues, we proposed a dual uncertainty-guided multi-model pseudo-label learning framework (DUMM) for semi-supervised medical image segmentation. The framework consisted of two main parts: The first part is a sample selection module based on sample-level uncertainty (SUS), intended to achieve a more stable and smooth training process. The second part is a multi-model pseudo-label generation module based on pixel-level uncertainty (PUM), intended to obtain high-quality pseudo-labels. We conducted a series of experiments on two public medical datasets, ACDC2017 and ISIC2018. Compared to the baseline, we improved the Dice scores by 6.5% and 4.0% over the two datasets, respectively. Furthermore, our results showed a clear advantage over the comparative methods. This validates the feasibility and applicability of our approach.

Published: January 2024

This study aimed to establish the relationship between the appendicular muscle mass index (AMMI), assessed from anthropometric variables, and the physical function of older people. Seventy-six older people participated in this study (72.03 ± 7.03 years). The participants underwent evaluations to determine their AMMI using anthropometry (weight, calf circumference, hip circumference, and knee height) and manual grip strength. Additionally, their physical function was evaluated using the 5-chair stand test, the 3-meter walk test, and the timed up and go test (TUG) to determine the strength of the lower limbs, the gait speed, and the dynamic balance, respectively. The results show that the AMMI did not present a significant relationship with the 5-chair stand test in both women (r = -0.135; p = 0.204) and men (r = -0.067; p = 0.349). The AMMI was moderately correlated with the gait speed in both women (r = 0.542; p < 0.001) and men (r = 0.556; p < 0.001). Finally, a statistical significance was observed in the relationship between the AMMI and the TUG test in women (r = -0.273; p = 0.047) and older men evaluated in this study (r = -0.284; p = 0.042). In conclusion, there is a relationship between the AMMI and both the dynamic balance and the gait speed. Therefore, the AMMI emerges as a potential public health assessment by enabling the clinical quantification of muscle mass and an estimation of physical function in the elderly population.

Published: January 2024

This study aims to assess the incorporation of virtual reality (VR) photography into the web-based immersive application “virtual interactive campus tour (VICT).” This application offers users an immersive experience, allowing them to virtually explore university campuses and access information about the facilities and services available. The VICT application offers a cost-effective, attractive, and sustainable alternative for universities to display their resources and interact with potential students. Through black box testing, we conducted user acceptance testing (UAT) and functionality testing, confirming the application’s readiness for deployment and its capability to meet institutional and end-user requirements. This study also examined the potential for universities to use VR to meet the expectations of prospective students. The application is compatible with both desktop and mobile devices. The results indicated that the overall average validity score was 0.88, suggesting that the measure is valid. The validation results were thoroughly tested and reliable. This study emphasizes the potential of immersive web-based tours in higher education and aims to bridge the divide between virtual exploration and physical visits. By offering an immersive virtual campus experience, this innovative tool has the potential to revolutionize university marketing strategies, increase student engagement, and transform campus visit approaches.
Are fast e-bikes an alternative to motorised individual transport? An exploratory study in Lausanne, Switzerland
Authors: Ravalet Emmanuel , Marincek Dimitri , Rérat Patrick
Published: January 2024

Sales of electrically assisted bicycles (e-bikes) have risen significantly in Europe. Almost all e-bikes provide assistance up to 25 km/h (“pedelecs”), but in Switzerland, more than 10% are speed pedelecs (s-pedelecs) offering assistance up to 45 km/h. Due to their increased speed, s-pedelecs hold great potential for long-range trips outside urban areas. Yet, to date, they have received very little academic attention. This exploratory paper fills this gap by questioning the place S-pedelecs have, compared to pedelecs, among transport modes and to what extent their greater speed can help them compete with cars more efficiently than pedelecs? We address in this paper, for both pedelecs and S-pedelecs users, the demographic characteristics, motivations for purchasing, travel patterns, as well as the modal shift effects. It draws on a survey conducted in Lausanne, Switzerland, among users of n=215 s-pedelecs and n=1205 pedelecs.Compared to regular e-bikers, s-pedelec users are more likely to be male, but otherwise share similar motivations to riding their e-bike. S-pedelecs are often used for long-distance commuting and compete more with cars and motorised two-wheelers. As a result, 60% of s-pedelec owners use a car less, and 20% decided to give up car ownership. Regression models confirms these results. Given the potential of s-pedelecs to replace motorised modes, we recommend devoting more attention to the development of infrastructure, such as interurban cycle highways, to accommodate them on a metropolitan scale.
Le discours du pathétique pour la quête de la solitude dans les confessions, les dialogues et les rêveries du promeneur solitaire de Jean-Jacques Rousseau
Authors: Ndiaye Abdou
Published: January 2024

Il existe chez l’auteur des promenades, des Confessions, de l’Émile et de la Nouvelle Héloïse une relation particulière qu’il entretient avec l’écriture qui semble fonctionner comme un lieu de mémoire où le persécuté pourra se ressourcer, un lieu favorable à la rédemption et un bouclier sûr contre les attaques de toutes sortes, même celles de ses propres désirs. Ainsi, dans la quête de son identité, plusieurs possibilités s’offrent-elles à lui pour retrouver la stabilité du moi et qui résident dans la manipulation scripturale. Face aux attaques de ses ennemis, comment Rousseau s’érige-t-il en victime ? Le présent article est une étude critique des œuvres autobiographiques de Rousseau. Il a pour objectif de montrer comment cet auteur dispose de son verbe créateur pour appâter le lecteur par les sentiments. Ainsi devant les souffrances, la fuite du temps qui entraîne sa future déchéance, montrerons-nous comment l’élégie, le chant intérieur et l’émotion du style se chargeront de transformer les attaques de ses détracteurs en énergies le rapprochant de son lecteur.

Le biais de la raison pour l’esprit et le langage humain. Par rapport à quelques autres animaux
Authors: Perrin Laurent
Published: January 2024

Le premier volet de cette étude, d’inspiration neuropsychologique, compare l’organisation de l’esprit à celle d’un édifice constitué d’un rez-de-chaussée sensoriel, accédant à un premier étage dévolu à l’expérience consciente de ce qui constitue la source de nos sensations, que surplombe finalement un étage supérieur consacré aux opérations de la raison dans le cerveau humain. La plupart des animaux disposent d’un esprit qui sera abordé sous l’angle de nos aptitudes respectives à accéder à la conscience, à partir des sensations primordiales dont cette dernière procède à la base. La dynamique opérationnelle de l’esprit humain mobilise en ce qui la concerne les trois niveaux d’opérations en question, dont résultent à l’arrivée différents biais cognitifs susceptibles de modifier la qualité des représentations mentales qui nous viennent à l’esprit. Le second volet poursuivra l’analyse de ces opérations de l’esprit sous l’angle de leurs propriétés sémiolinguistiques. Nous analyserons à cet effet certains aspects de ce qui distingue sémiotiquement la transmission des informations sensorielles ascendantes dont procèdent nos expériences empiriques, par rapport aux relectures descendantes dont elles font l’objet par les aptitudes linguistiques de notre conscience raisonnée. Le biais de la raison sera présenté comme une particularité de l’esprit humain consistant à accommoder nos expériences empiriques aux raisons objectives qui s’y rapportent, dont résultent notamment certaines difficultés théoriques relatives à l’appréhension de ce dont cherchent à rendre compte les sciences du langage et la psychologie. Quant au troisième volet, il aura pour objectif de proposer une issue susceptible de surmonter ces difficultés par un renversement de l’ordre prioritaire accordé à la langue par rapport à la parole, dans le cadre de nos interprétations verbales. Compte tenu de l’espace à disposition, ce troisième volet ne fera qu’esquisser les enjeux d’une réflexion consistant à prendre au sérieux la question posée dans ce volume, relative à la parole prêtée aux autres animaux lors de nos interactions, tout comme dans la création littéraire, et jusque dans les croyances animistes qui ont jalonné l’histoire de nos sociétés humaines. Nous nous en tiendrons sur ce point à ce qui concerne nos interactions quotidiennes avec les autres animaux.
Voix sans discours, discours sans voix : sur quelques anecdotes animalières du xvie siècle
Authors: Huchard Cécile
Published: January 2024

Les recueils d’histoires admirables ou prodigieuses qui connaissent une grande vogue au xvie siècle font souvent une part importante aux anecdotes animales. Elles croisent croyances et connaissances empruntées aux savoirs antiques, observations éthologiques et visée morale ou édifiante. Alors même que les animaux sont caractérisés, selon la tradition aristotélicienne et la théologie chrétienne, comme dénués de « logos », il s’agit de voir, à partir d’exemples pris chez P. Boaistuau, F. de Belleforest et Camerarius, comment certaines anecdotes mettent en scène des animaux qui semblent « parler » par des comportements signifiants et font valoir des valeurs telles que le juste et l’injuste, amenant, par-delà les interprétations dont ils font l’objet, les auteurs à s’interroger sur la nature animale.
Transcatégorisation grammaticale : focus sur les interrelations entre adjectif qualificatif et adverbe à travers les échanges en ligne entre enseignants
Authors: Taous Tatiana
Published: January 2024

La contribution étudie la transcatégorisation grammaticale entre adjectif et adverbe et démontre que ce phénomène constitue un angle mort dans le champ de la didactique de la grammaire, alors même qu’il pourrait permettre de résorber les préoccupations des enseignants, telles qu’elles ressortent de leurs échanges informels en ligne. Le travail s’organise en trois temps : un premier point étudie les agoras relatives, de près ou de loin, à la transcatégorisation adjectif-adverbe et détermine les enjeux didactiques de cette question ; nous poursuivons en rappelant la pertinence de ces questionnements au regard de la diachronie et du diasystème du français avant de proposer quelques supports d’énoncés invitant à concevoir la transcatégorisation comme un fait de langue dynamique et, plus largement, à rompre avec une vision normative et autocentrée de la grammaire.

Published: January 2024

Transportation companies operating both domestically and internationally are starting to worry about the safety of cargo freight. Utilizing a GIS-based port-to-port expedition safety monitoring system based on global information system is the appropriate way to handle the security and safety concerns in cargo assets because cargo crime is the largest difficulty facing supply chain companies. Reports will be sent in real time by the system to the central office via the data communication network. The application of tracking and traceability systems (tracking), dispatch (cargo loading and unloading), and access authority for cargo operations are the main topics of this study. Waterfall systems and system design using UML diagrams are the methods utilized in system development. This system employs GPS tracking technology with a digital lock for expedition operations where the position of the cargo dispatch, the location of the pick-up, and the open and closed status of each door container padlock during the field logistics' loading and unloading operations are all tracked in real time.

Innovative Engineering Solutions for Short Neutral Section Maintenance Reduction in Railway Overhead Lines
Authors: Jain Ishant , Upasani Raghav
Published: January 2024

This work addresses the challenges associated with the development of short neutral sections (SNS) for overhead lines of high-speed moving trains. A crucial function of a short neutral section is to provide electrical isolation between the different phases of AC traction. These sections are typically located in proximity to the traction substation and sectioning posts. The current SNS design presents several issues, including pantograph arcing, wear and tear of the overhead line system, and the need for manual rotation during periodic maintenance. To address these challenges TRIZ is used, a problem-solving methodology that leverages inventive principles to generate innovative solutions. The work outlines the use of several TRIZ tools and techniques, including the Interaction Matrix, Functional Analysis, Function-Body Diagram (FBD), Trimming, and the Contradiction Matrix [1]. With the application of these tools, the author presents several potential solutions for improving the SNS design to eliminate periodic maintenance and services. One proposed solution involves the use of a segmented overhead line system with an insulating cylinder-shaped discrete insulator to ensure smooth contact of the pantograph. Another solution involves the use of a twisted strip-based insulator to replace linear motion with rotating movement, eliminating the need for manual rotation. The work emphasizes the importance of considering various factors, such as design, material, wear rate, maintenance, and creepage distance, when evaluating the feasibility of these solutions. By leveraging TRIZ to generate innovative solutions, the author demonstrates the potential of this methodology to drive innovation and overcome complex challenges in the development of short neutral sections for high-speed rails.

This paper investigated the behavior of a DSTATCOM in the face of contingencies that may arise in an electrical power distribution network. It shows that DSTATCOM is an effective attenuator to limit the impacts of perturbations on the distribution network. The model equations are simulated in a MATLAB environment and have shown that the exactitude of the network parameters is a key determinant of the resilience of a disrupted distribution network in the presence of an optimally positioned DSTATCOM at a node. The capacitive current of the DSTATCOM increases inversely with a bad power factor and a critical voltage drop. The DSTATCOM in a network is therefore more solicited when the operating parameters of this network degrade as a result of single-phase or multiphase short circuits. Distribution system operators must therefore design protection plans that truly and sustainably limit the impacts of short circuits on distribution systems.

Published: January 2024

This paper presents a case study of solar drying of hydroxide sludge in the region of Marrakesh, Morocco. The experiments of solar greenhouse drying processes of the hydroxide sludge were studied in summer and winter seasons. The representative samples were in three volumes. The greenhouse sludge dryer was designed and constructed as a horticultural plant. Results showed that the dry of the three samples was reached in only 13 hours in summer and 25 hours in winter. The time of solar greenhouse drying registered was significantly lower compared to several studies. The higher values of drying rate were obtained in early hours of experiments in summer. The maximum ranges obtained were 0.25 kg water/kgDS.h for the hot season and 0.020 kg water/kgDS.h for the cold season. The important influence of the temperature had a greater effect with wind speed on drying rate. The sludge water evaporation caused a large volume reduction with a shrinkage during the processes in both seasons.
Numerical Investigation of Two Methods to Reduce the Settlement of a Light-Weight Highway Embankment on Soft Soils
Authors: Louadj Samia , Nateche Chahinez
Published: January 2024

The development of road and highway networks sometimes involves passing through compressible soils of poor quality. Given their mechanical properties as foundation soils, these soils are characterized by low short-term shear strength, expressed by undrained cohesion, which increases during soil consolidation, and are also characterized by significant compressibility, resulting in large-scale settlements when a load is applied to them. Nowadays, there are reinforcement methods that make it possible to execute these structures while limiting the risks of instability. This study consists of the numerical analysis of a light-weight embankment of a highway section built on soft soils. Two reinforcement methods are investigated to support the embankment layers and reduce settlement. Interest is given to the behavior of the soils in place before and after the installation of the adopted reinforcement. The analysis is carried out in such a way as to show the importance of the complete consolidation of the soils in place in the long term, which makes it possible to take into account the dissipation of the pore pressures.

Most of the coal mining in Indonesia that uses the open pit mining method faces serious problems, namely the treatment of acid mine drainage. This constitutes a relatively large volume of wastewater, especially in areas that have rainfall in the range of 2000–4000 mm yearly. Acid mine drainage as acidic wastewater formed during excavation cannot be avoided due to the oxidation process during overburden removal. The acidic wastewater that has formed must be managed strictly and appropriately prior to being released into public waters. There are two methods of treating acid mine wastewater, namely active and passive treatments. Active treatment is generally used more frequently during operations, considering the time, effort, and costs; however, when entering the mine closure period, natural processes must be used at lower costs. Undertaking passive treatment in this area has shown a reduction in the chemical materials used and has enabled a greater amount of wastewater to be managed. The purpose of this research is to describe the active and passive treatment processes in the management of acid mine drainage and to analyze the results of passive treatment in preparation for the mine closure stage. Development of passive treatment by swampy forest system can reduce cost of treatment, naturally process and more environment friendlier by reducing the quicklime materials.

Published: January 2024

Electrospinning is a cost-effective and versatile technique to fabricate continuous fibers ranging from submicron diameter to nanometer diameter. Polybutylene adipate-co-terephthalate (PBAT) has been investigated as a fibrous scaffold because of its low crystallinity, rapid biodegradability, and excellent mechanical properties, particularly for its high toughness and flexibility. However, the potential of the PBAT fibrous scaffold for medical purposes is still limited. PBAT blends with biocompatible polymers have been developed and investigated for tissue engineering applications. Herein, the preliminary research examines the processability of neat PBAT as a fibrous scaffold by varying several electrospinning processing parameters, such as solution concentration, voltage, flow rate, and tip to collector distance. The aim is to obtain continuous, smooth, and bead-free fibers. The electrospun fibers were examined using a scanning electron microscope (SEM) to determine its diameters. The optimum parameters for obtaining a continuous, bead-free PBAT fibrous scaffold were 20% w/v concentration, 19 kV voltage, 2 mL/h flow rate, and a 15 cm distance.

Background: Iron deficiency is highly prevalent in patients with heart failure and has well established diagnostic criteria. Its occurrence is associated with reduced quality of life, exercise capacity and increased hospitalization rates and mortality. The clinical efficacy of treating iron deficiency has not been tested in patients with heart failure with preserved ejection fraction (HFpEF). Methods: The FAIRHFpEF trial aims to enroll patients with HFpEF, reduced exercise capacity and iron deficiency (defined as serum ferritin <100 ng/mL or serum ferritin 100299 ng/mL with transferrin saturation <20%). Patients will be treated in a multicenter, doubleblind, randomized clinical trial with intravenous ferric carboxymaltose (FCM) at doses aimed to replenish iron stores vs. placebo. The primary endpoint is the difference in exercise capacity from baseline to week 24 as assessed by the 6minute walk test. Secondary endpoints include healthrelated quality of life assessments such as the Kansas City Cardiomyopathy Questionnaire, the European Quality of Life5 Dimensions questionnaire and global function tests. Conclusions: The FAIRHFpEF trial is designed to investigate the effect of intravenous iron repletion in iron deficient patients with HFpEF using FCM.
A Fine Balance? Value-relations, Post-capitalism and Forest Conservation—A Case from India
Authors: James Annie , Broome Neema Pathak
Published: January 2024

The serious need for anti-capitalist theory and action in a crisis-ridden world is widely acknowledged. Recent scholarship in conservation abides by this understanding, and finer deliberation on the links between radical theory and ongoing practices have grown but are still marginal. In this article, we study a case of community forest governance in Korchi, Maharashtra in India, where 87 village institutions and their federation have been striving to govern and manage surrounding forests in ecologically-sustainable and democratically-collective ways. Using Marx’s labour theory of value and metabolic rift concept, in combination with Ariel Salleh’s notion of metabolic value, we explore how Korchi’s attempt at eco-sufficiency is premised upon a fine balance between different values its villagers associate with their forests. This requires us to see Korchi’s villagers as meta-industrial labourers, a term Salleh uses for workers whose labouring practices—marked by care and reciprocity—typically lie on the margins of capitalism. Using the (analytical) lens of value relations, we show how such practices towards forests help sustain a healthy metabolic relation between humans and nature, not dominated by exchange value concerns. We thus offer conceptual nuance on how post-capitalist theory can better support the real-world practice of alternatives to mainstream conservation.
Conceptualizing Fear of Progression in Cardiac Patients: Advancing our Understanding of the Psychological Impact of Cardiac Illness

Published: January 2024

Background:

An emerging area of psycho-cardiology explores fear of disease progression in cardiac patients, following extensive research of this topic in psycho-oncology. Novel interventions that target cardiac fear of progression(FoP) may be valuable in bridging the gap between the high psychological support needs in cardiac care and limitations surrounding the efficacy of standard psychosocial treatments. However, there appears to be limited research characterizing FoP in cardiac patients with which to inform potential interventions.

Aims:

Using a mixed methods approach in two inter-related studies, we aimed to develop a preliminary conceptualization of cardiac-FoP.

Methods:

Study 1 involved a scoping review of existing qualitative research to identify the range of fears relating to disease progression reported by cardiac patients. Study 2 investigated the prevalence and distress levels associated with a selection of fears identified in Study 1 through a quantitative study of 194 cardiac patient admissions at two Australian hospitals.

Results:

Study 1 conceptualized cardiac-FoP in two ways, by the content of the fears and by the behavioral responses to the fears. Fears were categorized into seven broad domains: fears associated with death, health, interpersonal relationships, treatment, accessing help, role responsibilities, and physical activity. Five categories of behavioral responses were identified: avoidance, hyperawareness, symptom misattribution, seeking help, and lifestyle changes. Study 2 indicated a high prevalence of fear, with an average endorsement of 40.9%. When fear was endorsed, an average of 45.2% of cardiac patients experienced moderate-to-severe distress.

Discussion:

This paper provides an initial conceptualization of FoP in cardiac patients, providing preliminary evidence of the rates of fear and associated distress in this population. Drawing on this conceptualization, unique measurement tools and interventions should be developed to identify and address FoP in cardiac patients.
