Published: February 2025

Introduction: This study aims to assess the prevalence, sociodemographic factors, and patterns of mandible fractures at Prof. dr. I.G.N.G. Ngoerah General Hospital, recognizing that more than half of all maxillofacial injuries are due to mandible fractures, attributable to the mandible's prominent structure.Methods: This retrospective study was held in Prof. dr. I.G.N.G. Ngoerah General Hospital. Data were collected from January 2018 to December 2023. A total of 289 samples were included in this study. Age, gender, anatomical location of the fractures and unilateral/bilateral involvement were reported. Results: During the period spanning January 2018 to December 2023, a comprehensive analysis of 289 mandible fracture cases was conducted. Notably, the highest incidence was observed in 2022, comprising 72 cases. Predominantly affecting males (72.7%) within the age bracket of 21-30 years (40.1%), these fractures were primarily attributed to road traffic accidents (64.4%), often associated with alcohol influence (43.9%). Remarkably, non-helmet usage was prevalent among the majority of patients (69.9%), particularly motorcycle drivers (53.3%). The parasymphysis region emerged as the most frequently affected area (38.1%), with unilateral involvement prevailing in the majority of cases (61.6%). Additionally, associated injuries were noted in 88.5% of cases, with management predominantly comprising open reduction internal fixation (ORIF) complemented by maxillomandibular fixation (MMF) in 66.8% of cases.Conclusions: The findings of this study reveal a progressive rise in the annual incidence of mandible fractures. Consequently, there is a pressing need to heighten awareness among healthcare practitioners when managing patients presenting with maxillofacial traumas.

Coordinated Minimum Wage Policies: Impacts on EU-Level Income Inequality
Authors: Filauro Stefano , Grünberger Klaus , Narazani Edlira 
Published: February 2025

Abstract
Several studies have shown that minimum wage policies have the potential to mitigate income inequality. Both EU-level and national policies have sparked discussions regarding the adequacy of minimum wages and their impact on income inequality at the country level. However, the impact on EU-level income inequality of coordinated minimum wage policies remain uncertain. While upward convergence in minimum-wage settings across countries may reduce inequality within countries, it could also exacerbate disparities between them. This study assesses the EU-wide impact of minimum wage policies beyond national effects. Using a microsimulation model and assuming negligible employment effects, our results suggest that implementing a hypothetical minimum wage set at 60 % of the national median wage in EU countries would result in a limited yet significant reduction in EU-level income inequality (by 0.6 % in 2019, as measured by the Gini index). This reduction stems from a relative decrease in both within-country and between-country inequality, although the absolute reduction in Gini points is more pronounced for within-country inequality. Notably, the percentage reduction in inequality is broadly similar for both market and disposable incomes. However, the withdrawal of social benefits due to higher minimum wages appears to offset part of this reduction in market inequality.
Tree-based conditional copula estimation
Authors: Bonacina Francesco , Lopez Olivier , Thomas Maud 
Published: February 2025

Abstract
This article proposes a regression tree procedure to estimate conditional copulas. The associated algorithm determines classes of observations based on covariate values and fits a simple parametric copula model on each class. The association parameter changes from one class to another, allowing for non-linearity in the dependence structure modeling. It also allows the definition of classes of observations on which the so-called “simplifying assumption” holds reasonably well. When considering observations belonging to a given class separately, the association parameter no longer depends on the covariates according to our model. In this article, we derive asymptotic consistency results for the regression tree procedure and show that the proposed pruning methodology, i.e., the model selection techniques selecting the appropriate number of classes, is optimal in some sense. Simulations provide finite sample results, and an analysis of data of cases of human influenza presents the practical behavior of the procedure.

WO6 is synthesized by using citrate – gel method. This double perovskite structure compound is prepared at different concentrations i.e. (x = 0.0–0.24) at different temperatures 500, 600, 700 °C for 5 h. Further, the prepared samples are characterized through different tools like XRD (X-ray diffractro meter), UV Visible Diffuse Reflectance Spectra, Photo luminescence spectra, FE SEM and CIE Software and the prepared sample shows different structures in various concentrations by using X-ray diffractrometer. Similarly, lattice parameters, peak positions are explained for all various concentrated samples at 700 °C sintered temperature for 5 h. However, the samples which are sintered at 700 °C for 5 h are excited at different wavelengths i.e. 395, 465, 540 nm, the corresponding emission intensities are also recorded. All the concentrated samples exhibits towards high intensity peaks at 595, 614 nm wavelengths in their emission spectra. The sample x = 0.12 shows highest red emission intensity out of all concentrations in the emission spectra. 5D0-7F1 & 5D0-7F2 are the major transitions formed in the emission spectra for every concentrated sample. In the same way the structural morphology is identified clearly by using FE SSEM. The CIE color coordinators are calculated and identified as very close to NTSC coordinators of red phosphor. Finally, the color purity is also calculated to analyze the quality of red light for the prepared red phosphor which is used in different W-LEDs applications.
Influence of gas nitriding on the surface layer of M50 NiL steel for aerospace-bearing applications

Published: February 2025

Abstract
Currently, there is an increased demand for M50NiL steel from the aerospace, automotive, and nuclear industries to improve the characteristics of components, such as wear resistance, fatigue resistance, and surface hardness, while maintaining its corrosion resistance. Previous research has demonstrated that the nitride parameters are duration, temperature, and flow rate. The current investigation examines the efficacy of gas nitride on M50NiL steel from 500 to 550°C over 08–90 h according to the specific requirements of the specimens maintaining a gas ratio of 75:25 (NH3:NH3diss), a typical operational pressure within the range of 1–2 mbar, and an NH3 flow rate of 0.4–0.5 l min−1. Using a hydrogen chloride mixture as an activator for the steel surface, gas nitriding (GN) treatment is carried out in a partially dissociated ammonia atmosphere, resulting in the formation of the layers that are seen. In order to examine the phase transitions within the phase architecture and the chemical constituents of the gas-nitrided layer, methodologies such as energy-dispersive spectroscopy (EDS) and X-ray diffraction (XRD) were employed. The M50 NiL steel specimen, subjected to a thermal treatment at 550°C for a duration of 12 h, was found to possess an anomalously elevated concentration of nitrogen, according to the EDS evaluation. The results obtained from the XRD analysis of the gas nitrided layer indicated the existence of iron nitride phases, predominantly comprising α′-Fe, γ′-Fe4N, and α′N (nitrogen-enriched martensite). By micro-hardness assessment, it is apparent that at a temperature of 500°C over 24 h, the highest hardness value of 1,070 HV was achieved in the nitrided sample, which is approximately fourfold greater than that of the untreated specimen. In the case of case depth, it was observed that at 550°C for a duration of 24 h, the GN treatment resulted in a maximum case depth of 134 μm. The M50NiL specimen, designated GN 500, which underwent nitriding for 24 h, demonstrated the greatest wear resistance among the nitrided samples. Nitrided specimens are subjected to characterization along with electrochemical potentiodynamic corrosion assessment in an aerated 3.5% NaCl solution. The electrochemical evaluations indicated a substantial reduction in the corrosion current density of the specimen’s post-nitriding, accompanied by a shift in the corrosion potential toward the noble direction with the extension of nitriding duration. The results of M50 NiL steel surface characteristics are enhanced after applying gas nitride coating. The findings indicate that controlled pressure GN effectively inhibits the precipitation of chromium nitrides, which is advantageous for the attainment of a thicker nitrided layer.
Bound polariton states in the Dicke–Ising model
Authors: Román-Roche Juan , Gómez-León Álvaro , Luis Fernando , Zueco David 
Published: February 2025

Abstract
We present a study of hybrid light–matter excitations in cavity QED materials using the Dicke–Ising model as a theoretical framework. Leveraging linear response theory, we derive the exact excitations of the system in the thermodynamic limit. Our results demonstrate that the cavity can localize spin excitations, leading to the formation of bound polaritons, where the cavity acts as an impurity of the two-excitation band, localizing spin-wave pairs around single-spin domains. We derive the condition for the existence of these bound states and discuss its satisfiability in different regimes. Finally, we show that these effects persist in finite systems using exact-diagonalization calculations.

Published: February 2025

Abstract
Photodetectors are crucial for modern technologies such as optical communications, imaging, autonomous vehicles, and machine vision. However, conventional semiconductor-based photodetectors require additional filtering systems due to their broad spectral response, leading to increased costs and complexity. Here, we present a narrow spectral response photodetector using hexagonally arranged plasmonic Au nanohole structures, eliminating the need for optical filters. The device achieves a full-width at half maximum (FWHM) bandwidth of ∼40 nm with a response peak at 760 nm and a linear photocurrent responsivity of 0.95 μA/W. The photothermoelectric effect, induced by the nonradiative decay of plasmonic resonance, converts optical radiation into an electric potential on the Au surface. The hexagonal nanohole design generates polarization-independent photocurrents and allows spectral tuning beyond the cutoff region of silicon photodetectors. This versatile approach enables customizable response characteristics across a broad wavelength range through geometric design, enhancing its potential for diverse applications.

Published: February 2025

Abstract
Augmented and virtual reality (AR/VR) is transforming how humans interact with technology in a wide range of fields and industries, from healthcare and education to entertainment. However, current device limitations have impeded wider integration. Tunable holographic metasurfaces represent a promising platform for revolutionizing AR/VR devices by precisely controlling light at the subwavelength scale. This article examines current challenges and opportunities from both the AR/VR and holographic metamaterial perspectives and explores how improvements to state-of-the-art approaches can address these challenges. In particular, we propose a focus on easily manufacturable and broadly electrically tunable metasurface technologies including liquid crystal integration and excitonic tuning in 2D materials. Advanced metasurface optimization techniques including machine learning will also be crucial for exploring the large design space.
Research on a path-tracking control system of unmanned rollers based on an optimization algorithm and real-time feedback
Authors: Ma Haosen 
Published: February 2025

Abstract
The unmanned double steel wheel vibration roller enhances high-quality unmanned compaction operations by ensuring precise walking control, thus avoiding human error-related issues like under- and over-compaction. However, its complex construction technology, cooperative operation challenges, and high construction quality demands present significant difficulties for unmanned operation. This study addresses the challenges associated with compaction mechanisms and construction technology. It analyzes the interaction between the vibrating roller and the compacted material using the U-K equation to develop a dynamic force model, which leads to a method for determining optimal compaction parameters. Simulations reveal that the compaction speed of the three rollers is approximately 0.3 m/s, and the parameter optimization module performs as anticipated. The simulated pilot roller effectively executes motion planning under various compaction conditions, with an overlap distance of about 0.2 m between adjacent rolling belts after lane changes. This overlap, which is 0.5 times the width of the 0.4 m steel wheel, successfully prevents both under-compaction and over-compaction. A cluster motion planning strategy, based on a pilot-following structure, is proposed for the roller cluster in the compaction area. The strategy includes designing the following roller formation based on the compaction operation range and roller group configuration parameters.

Abstract
Ultrasonic welding (USW) is utilized to join identical and non-identical materials, with and without a thermoplastic composites or thermoset composites coupling layer, or with different shapes of energy directors or adhesive materials. Due to its emerging structure, joining carbon fiber (CF)-reinforced polymer has become imperative due to the developed concerns in different industrial and manufacturing sectors. This review article covers all types of joined CF-reinforced polymers, including similar/dissimilar CF-reinforced thermoplastics or CF-reinforced thermosets joined by USW, considering different types of USW (spot welding, continuous welding). This review considers various welding process parameters and their impacts on welding quality, welding strength, and mechanical and microstructure characterizations of the welded joint. Also, improving the USW joints and their challenges are discussed. The fabrication processes of the polymer matrix composite and various polymers are addressed. In addition, the recyclability of CF-reinforced polymer is highlighted. A key finding from this review is that polyetheretherketone and both types of nylon (PA6 and PA66) show high exceptional characterizations, making them more favorable for developing CF-reinforced thermoplastics over other types of polymers. While a unique co-curing process must be completed for the adhesive material before performing the USW, welding energy is the most effective process parameter that enhances the mechanical properties when using adhesive bonding before USW.

Published: February 2025

Media is a channel for information that is still used today. There are many issues circulating with various media reporting them. One of the issues that is always widely discussed is the Palestinian-Israeli conflict which is heating up again at the moment. The discourse on Palestinian liberation has always been a hot topic. This gives rise to the emergence of lexemes or language units that are appropriate to the Palestinian-Israeli conflict, such as the word tahrir. This research aims to explain the lexical and contextual meaning in the online Arabic media Al-Jazeera which highlights the Palestinian-Israeli conflict. This research is descriptive qualitative research. The data source comes from Al-Jazeera media with the help of AntConc and LancBox software in collecting data. The research results showed that lexical meaning was found by 64% and contextual meaning was found by 36%. Al-Jazeera reporting tends to use the word tahrir in its lexical meaning as liberation. Meanwhile, using the word al-tahrir has a contextual meaning that is oriented towards the name of the liberation organization in Palestine.
Roman Ingarden's Spaces of the Word. Part 1
Authors: Ulicka Danuta 
Published: February 2025

The article delves into the literary oeuvre of Roman Ingarden, the prominent Polish phenomenologist, philosopher, aesthetician, and literary theorist. While his scholarly contributions are globally acknowledged, his literary output, in stark contrast, remains largely undiscovered, archived within the confines of his family collection, with only sporadic references in dispersed texts. Intriguingly, some portions of his literary creations were purportedly prepared for publication by the author himself. This corpus of work, primarily comprising poetry but also prose, drama, and autobiographical writings, unveils not only Ingarden’s artistic predilections – ranging from thematic and stylistic inclinations to genre preferences and rhythmic patterns, exhibiting clear affiliations with Young Poland’s poetry – but also provides insight into the implicit conception of subjectivity embedded in his poetic compositions. This nuanced understanding significantly supplements and reinforces the overtly articulated notion of subjectivity present in his writings addressing Edmund Husserl’s philosophy. Additionally, Ingarden’s poetic works, when juxtaposed with the poetry of his contemporaries – such as Kazimierz Twardowski, Stefania Skwarczyńska, Maria Dłuska, Roman Jakobson, and Victor Shklovsky – assumes a pivotal role as an artifact, offering a lens through which to comprehend the prevailing cultural milieu of the epoch. Simultaneously, it provokes the question of why outstanding innovators in literary studies exhibited an intriguing conservatism in their own literary endeavors.
