Authors: Bani Klodiana , Qoshja Arbër , Simoni Aurora , Uzuni Marselina
Published: November 2024

This article created the Odd Chen-Log-Logistic distribution from Odd Chen-G family distributions. We derive various statistical features. The parameter estimation theory focuses on selecting the best estimators. We estimate distribution parameters using maximum likelihood, moment, least squares, weighted least, L-moment, maximum product spacing, and minimal distance methods. We will examine Kolmogorov-Smirnov simulation studies that compare estimator efficiency. Finally, we analyze a genuine COVID-19 data set to demonstrate the flexibility of our model and its accuracy compared to other distributions.
New Minerals from the Redmond Mine, North Carolina, USA: IX. Siligiite, a Lead-Zinc Sulfate with a Novel Heteropolyhedral Sheet
Authors: Kampf Anthony R. , Smith Jason B. , Hughes John M. , Ma Chi , Emproto Christopher
Published: November 2024

The new mineral siligiite, [Pb(H2O)5(SO4)][Zn9(OH)18] (IMA2023-117), was found in the Redmond mine, Haywood County, North Carolina, USA, where it occurs in a highly unusual secondary assemblage that comprises a variety of rare Pb-Zn-Cu sulfates, thiosulfates, and carbonates. Siligiite was found in vugs in massive galena-sphalerite-chalcopyrite-quartz in close association with anglesite, bechererite, cherokeeite, cuprocherokeeite, elyite, kennygayite, leadhillite, and muscovite. Siligiite crystals are blades or flattened needles, up to about 1 mm long, with lengthwise striations, occurring in radiating clusters. The mineral is colorless with vitreous to silky luster. The mineral is brittle with splintery fracture and two cleavages: perfect on {001} and good on {100}. The Mohs hardness is about 2½. The calculated density is 3.513 g/cm3. The mineral is biaxial (+) with α = 1.624(3), β = 1.650(3), and γ = 1.656(3) (white light). The 2V is 50(2)° with distinct r > v dispersion. The optical orientation is Y = b,X ≈ c*, Z ≈ a. Electron probe microanalyses provided the empirical formula [Pb0.99(H2O)5(SO4)][(Zn8.81Cu0.19)Σ9.00(O0.9989H)18.02]. Siligiite is monoclinic, P21/n, a = 13.658(3), b = 9.488(3), c = 19.209(4) Å, β = 102.577(6)°, V = 2429.4(1) Å3, and Z = 4. The crystal structure of siligiite (R1 = 0.0576 for 5448 I > 2σI), contains a novel sheet comprised of Zn(OH)6 octahedra and Zn(OH)4 tetrahedra. A Pb2+ cation, an SO42− group, and several H2O groups are located between successive sheets.
Contesting “Moderate Islam”: Religious Legitimacy in Post–Civil War Algeria
Authors: Sakthivel Vish
Published: November 2024

Globalized security discourses over the last 20+ years have made “moderating” Islam into a hegemonic sociopolitical imperative across the so-called Muslim world, even while “moderate Islam” is largely bereft of an agreed-upon or specifiable meaning. This study analyzes the multitude of frames through which “moderation” (al-i‘tidal or al-wasatiyya) is deployed by Algeria’s Muslim Brotherhood–inspired Movement of the Society of Peace (MSP). I argue that the MSP deploys the discourse of “moderate Islam” in its official platforms, public image, and articulations of personal and collective identity among its membership base in order to situate the movement against global stigmas and within the political-cultural contours of post–civil war Algeria.

Authors: Karepesina Mochdar , Loupatty Linda Grace , Yuniarti Layn Yuyun
Published: November 2024

This study aims to determine the factors that influence the implementation of SAK EMKM in MSMEs in the culinary sector of Ambon City, the factors studied are Socialization, Educational Background, Business Size, Perception of MSME actors & Accounting Understanding. The data used in this study is primary data obtained through interviews with MSME actors in Ambon City. The informants in this study were MSMEs in the culinary sector located in Ambon City by taking 4 informants representing each range of Micro, Small and Medium. Data analysis techniques used data reduction, data presentation, and drawing conclusions. The results showed that the four informants had never received socialization from the government, but there was a perception factor of MSME actors that made them want to implement SAK EMKM. The educational background of accounting is relevant to financial reports, making informants able to implement SAK EMKM, and vice versa. MSME actors with medium business sizes can not only implement SAK EMKM but small and micro businesses can also. The four informants have the same perception regarding the benefits of financial reports based on SAK EMKM. Understanding accounting improves the quality of financial reports, helps develop business conditions and allows to effectively evaluate their financial performance
Пространственно-темпоральное моделирование дискурса рубрики «Арт» в изданиях Le mоnde и «Российская газета»
Authors: Н.Н. Шептун
Published: November 2024

В статье рассматривается явление сопряжения публицистического дискурса и искусствоведческого дискурса в статьях рубрики «Арт», представленной на страницах двух разноязычных государственных газет — франкоязычной Le monde и русскоязычной «Российская газета». Выявлено наличие различного количества размещенных в рубрике «Арт» статей за идентичный период, что обусловлено актуальностью тематики статей рубрики для французского и российского общества. Определено, что в проксемно-темпоральном сегменте информативного кода статей двух газет превалируют хронемы, среди которых точечные хронемы, предельные хронемы, пролонгированные хронемы, обобщающие хронемы. Проксемные маркеры менее частотны по сравнению с темпоральными маркерами. Установлено, что в таксономической сравнительно-сопоставительной модели дискурса проксемно-темпоральный сегмент информативного кода в материале на французском и русском языках обладает одинаковым свойством: этот сегмент сопряжен с лингвокультурным сегментом, выраженным лингвокультуремами, что предопределяет синергию двух типов дискурса в статьях рассмотренной рубрики «Арт» в разноязычных газетах.

The article deals with the phenomenon of combining journalistic discourse and art historical discourse in articles in the “Art” section, presented on the pages of two multilingual state newspapers, the French newspaper Le mondeand the Russian newspaper Rossiyskaya gazeta. The presence of a different number of articles presented in the “Art” section for an identical period was revealed, which is predetermined by the relevance of the topics of the articles in the section for French and Russian society. It has been determined that in the proxemic-temporal segment of the informative code of the articles of two newspapers, chronemes prevail, including point chronemes, limit chronemes, prolonged chronemes, and generalizing chronemes. Proxemic markers are less frequent than temporal markers. It has been established that in the taxonomic comparative model of discourse, the proxemic-temporal segment of the informative code in the material in French and in the material in Russian have the same property, namely this segment is associated with the linguocultural segment expressed by linguoculturemes, which predetermines the synergy of the two types of discourse in the articles reviewed “Art” columns in multilingual newspapers.
Вариативная передача контаминированной речи персонажей-немцев (на материале рассказов О. Генри The purple dress и The last leaf)
Authors: А.А. Стрельцов
Published: November 2024

В статье исследуется то, как переводчики двух рассказов О. Генри, опубликованных в начале XX века, учитывают в прямой речи особенности произношения немецкоязычных персонажей. Эти персонажи длительное время проживают в США и владеют английским языком на уровне, достаточном для осуществления успешного общения с другими персонажами, для которых этот язык родной. Цель исследования — выявление способов перевода реплик персонажей-немцев, содержащих искажения английской речи. Материалом послужили фрагменты, полученные методом сплошной выборки из семи переводов рассказа The purple dress и девяти The last leaf. Обозначены как общие черты, характерные для обоих рассказов и большинства их переводов, так и отличия, обусловленные характерами персонажей и индивидуальными особенностями переводчиков.

The article features the way translators of O. Henry’s two short stories, written in the early XXthcentury, depict peculiarities of direct speech of German characters, who have lived in the U.S.A. long enough to be able to communicate effectively with other characters, for whom English is their mother tongue. The investigation shows how translators into Russian rendered the broken speech of Germans, who spoke English. With this aim in view, we have selected and analyzed such utterances, picked out from seven translations of The purple dress and nine translations of The last leaf. We have noted certain common features as well as individual peculiarities, that can be attributed to the personage’s or translator’s idiosyncrasies.

Estrategias Pedagógicas Significativas y Persuasivas en el Aprendizaje del Inglés
Authors: Arrieta Bettin Luz Elena , Aravena Domich Marcela Angelina
Published: November 2024

El propósito de este artículo es reflexionar sobre la importancia de las estrategias de enseñanza significativas, contextualizadas y persuasivas como estructurantes pedagógicos que captan el interés y motivación de los estudiantes de educación secundaria y media, hacia el aprendizaje del inglés como idioma extranjero. Reflexión cimentada en los resultados de la investigación realizada sobre dicha temática en tres colegios oficiales ubicados en el departamento de Boyacá, Colombia,  y de la cual se origina este; tras analizar algunos componentes fundamentales en cuanto a los métodos, procesos y recursos de enseñanza, y a la forma como contribuyen al aprendizaje del idioma, se presenta una serie de reflexiones en torno a la problemática que en el contexto se presenta, así como algunos criterios que se formulan como alternativa de transformación tanto en la didáctica del idioma extranjero, como en la actitud de los estudiantes hacia su aprendizaje. El principal hallazgo evidencia que la didáctica empleada  en el aula de inglés tiene insuficiente proyección entre la mayoría de estudiantes, razón por la que no se motivan hacia su aprendizaje. Se concluye que las imprecisiones existentes en relación con el escaso desarrollo de las competencias comunicativas en idioma inglés entre los estudiantes, se deriva de los impedimentos acerca de ser motivados suficientemente a aprender y utilizar el idioma inglés en situaciones comunicativas reales.

Authors: Sagñay Yánez Rosalinda Gardenia , Vaca Arauz Silvia Lorena
Published: November 2024

Este estudio realiza una revisión sistemática para evaluar el impacto de la estructura familiar, el entorno doméstico y el nivel educativo de los padres en el clima escolar y el rendimiento académico de los estudiantes de educación básica. Se siguió el protocolo PRISMA, analizando estudios publicados entre 2010 y 2023 en bases de datos como Scopus y Web of Science. La revisión incluyó investigaciones empíricas que abordaron la relación entre estos factores familiares y el rendimiento académico. Los resultados destacan que la calidad de las interacciones familiares es un factor más determinante que la estructura familiar en sí. El nivel educativo de los padres y un entorno doméstico que favorezca el aprendizaje se asocian con un mejor desempeño académico. Además, la participación activa de los padres en las actividades escolares mejora tanto el rendimiento académico como el clima escolar. Se concluye que el apoyo familiar, especialmente en contextos socioeconómicos desfavorecidos, es crucial para mejorar los resultados educativos. Este estudio subraya la importancia de políticas que promuevan una mayor colaboración entre las escuelas y las familias para optimizar el bienestar académico de los estudiantes

Published: November 2024

La inteligencia artificial en el nivel superior ha ayudado tanto a maestros para facilitar la enseñanza y adquirir nuevos conocimientos para que los alumnos puedan continuar aprendiendo de manera eficiente y al igual los alumnos de dichas instituciones en el nivel superior se les facilita más para aprender de manera individual y realizar los trabajos que se les asignen de una manera mejor elaborada, la inteligencia artificial ha ido creciendo desde el momento en que se comenzaron a surgir las ideas para comenzar con su desarrollo hasta el día de hoy de una manera increíble no solamente en las industrias en general sino también en las instituciones de nivel superior. Algo a tomar en cuenta es que las instituciones deben enfocarse en que la inteligencia de los alumnos al usar estar estas herramientas sea potenciada y no sea sustituida o se hagan en su totalidad dependientes de la inteligencia artificial, hay muchas ventajas de la inteligencia artificial implementada en el nivel superior, como, a su vez, también hay desventajas, se pueden ver cómo la tecnología va avanzando con el pasar de los años, lo cual también hace que la inteligencia artificial vaya avanzando en muchos aspectos y áreas, pero en el nivel superior es una gran herramienta, más se requiere la adaptabilidad de quienes la usen y que sea repartida de manera equitativa en las instituciones de nivel superior para con todos, para tener un buen y eficiente acceso a la inteligencia artificial, ya que no todos tienen acceso a ella de manera personal.

Published: November 2024

El presente proyecto de investigación tuvo como objetivo formular un protector solar con potenciales complejos fotoprotectores de origen natural. El estudio inició con la localización y recolección de la droga vegetal Taxo (Passiflora tarminiana), ñachag (Bidens andicola), maiz (Zea mays) y espinaca (Spinacea oleracea), que por métodos de maceración y percolación se obtuvo extractos hidroalcohólicos para finalmente obtener extractos secos. Se realizó el control de calidad y tamizaje fotoquímicos identificándose la presencia de saponinas, compuestos fenólicos y flavonoides. La medición del factor de protección solar se efectuó a partir del método espectrofotométrico de Mansur en el rango la longitud de onda de 290 a 320 nm (radiación UVB); a 500 ppm se determinó que los mejores extractos fueron Bidens andicola (16,80) y Zea mays (11,741). Posteriormente, se realizó la combinación de extractos, una vez analizadas las 66 combinaciones, en base al porcentaje de variación los extractos y la proporción ideal a emplear corresponde al 30% de Zea mays y 70% de Bidens andicola. El análisis del factor de protección solar de la emulsión fotoprotectora, a 300 ppm fue de 38,5; siendo evidente que la combinación de los extractos de Zea mays y Bidens andicola, potencia el efecto fotoprotector.
Robótica Educativa en Colombia: Percepciones y Desafíos en los Niveles de Educación Básica y Media
Authors: Redondo Polo Jannier Alfonso
Published: November 2024

La utilización de la robótica educativa (RE, en adelante) como estrategia didáctica, evidencia mejoras en ciertas habilidades del pensamiento computacional y tecnológico, al tiempo que genera aprendizajes significativos por su carácter real y lúdico. La utilización de la RE ha sido positiva para el fortalecimiento de las competencias tecnológicas y habilidades blandas, en tanto, varios autores refirieron su efectividad en los diferentes niveles educativos en que fue aplicada; por ejemplo, a temprana edad con robots de piso o botonera y a mediana edad, con robots programables con microcontroladores. Este articulo propone una revisión bibliográfica, de enfoque cualitativo, para analizar las percepciones y desafíos referentes a la aplicación de la RE en las aulas de educación básica y media. Así, se encontró que uno de los desafíos más importantes es el alto costo de los kits robóticos comerciales, lo cual desemboca una brecha digital y en consecuencia, se propone trabajar en iniciativas de robótica educativa accesibles y de bajo costo para su utilización en escuelas públicas colombianas.
Artificial intelligence and Artificial Neural Networks in toxicology: challenges, perspectives and applications (Narrative review)

Artificial Neural Networks (ANN) have great potential in toxicology research. They may be used to predict the toxicity of various chemical compounds or to classify compounds based on the toxic effects they have on the body or in the environment. Nowadays, numerous ANN models have been developed, some of which may be used to identify and possibly explain complex chemical-biological interactions in toxicological sciences. Tightly coupled multilayer perceptron’s may, under some conditions, have high classification accuracy and discrimination power in separating damaged from intact cells after exposure to a toxicant. Regularized and fully connected convolutional neural networks cannot detect and detect discrete changes in toxicity related two-dimensional data patterns. Bayesian neural networks with weight marginalization may sometimes have better prediction performance compared to traditional approaches. With the further development of artificial intelligence, artificial neural networks are expected to become an important part of various accurate and cost-effective biosensors for detecting various toxic substances and evaluating their biochemical properties in the future. In this brief review article, we discussed the recent researches focused on the scientific value of ANN in evaluating and predicting the toxicity of various chemical compounds and the challenges and limitations in the field of artificial intelligence and the use of artificial neural networks.

Published: November 2024

The health risks posed by climate change have extended into maternal and fetal health, with evidence linking changing environmental factors to a rise in conditions such as pregnancy-induced hypertension (PIH), cerebral venous thrombosis (CVT), and physiological jaundice, particularly in winter months. Additionally, post-viral infections and intrauterine infections have become more prominent in the post- COVID era, contributing to an increased risk of congenital anomalies, preterm labor, and intrauterine growth restriction (IUGR). The article also highlights the higher incidence of postpartum cardiomyopathy in African women and the challenges posed by long-distance travel during pregnancy. This article examines these trends and calls for more targeted research and interventions to mitigate these risks.

Authors: Lekarevičienė Egidija , Drejeris Rolandas
Published: November 2024

Around 11.3 million people work in the aviation sector worldwide. During 2020 and 2021, thousands of highly skilled aviation professionals lost their jobs or were retired. After easing travel restrictions in 2022, aviation began to recover rapidly, which was and still is a major challenge for the sector. Along with financial and technological challenges, there is the issue of retraining employees and renewing their competencies. In this era of non-stop progress, the main goal of the players in the aviation sector is to keep up with the changes. Artificial intelligence (AI) tools are rapidly being integrated in aviation operations, systems are being automated and ongoing digitization helps to manage increasing flow of information or travelers. Technological, digital, or regulatory changes create a constant need for new and diverse competencies in this field, which becomes a vital need for the sector to survive in the market. This article aims to review the regulations of competencies necessary for those working in aviation and create models to justify the need for professional competencies in aviation. It would reflect the constantly changing environment and its influence on aviation organizations. Therefore, the biggest challenge is to create a model as a sufficient tool to assess the need for competence in work activities.
Photometric Redshift Estimation of Quasars by a Cross-modal Contrast Learning Method

Published: November 2024

Estimating photometric redshifts (photo-z) of quasars is crucial for measuring cosmic distances and monitoring cosmic evolution. While numerous point estimation methods have successfully determined photo-z, they often struggle with the inherently ill-posed nature of the problem and frequently overlook significant morphological features in the probability density functions (pdfs) of photo-z, such as calibration and sharpness. To address these challenges, we introduce a cross-modal contrastive learning probabilistic model that employs adversarial training, contrastive loss functions, and a mixture density network to estimate the pdf of photo-z. This method facilitates the conversion between multiband photometric data attributes, such as magnitude and color, and photometric image features, while extracting features invariant across modalities. We utilize the continuous ranked probability score (CRPS) and the probability integral transform (PIT) as metrics to assess the quality of the pdf. Our approach demonstrates robust performance across various survey bands, image qualities, and redshift distributions. Specifically, in a comprehensive data set from the Sloan Digital Sky Survey and the Wide-field Infrared Survey Explorer (WISE) survey, our probabilistic model achieved a CRPS of 0.1187. Additionally, in a combined data set from SkyMapper and WISE, it reached a CRPS of 0.0035. Our probabilistic model also produced well-calibrated PIT histograms for both data sets, indicating nearly uniform distributions. We further tested our approach in classification tasks within the SkyMapper data set. Despite the absence of u, v, and g bands, it effectively distinguished between quasars, galaxies, and stars with an accuracy of 98.96%. This versatile method can be extended to other scenarios, such as analyzing extended sources like galaxies, across different surveys and varying redshift distributions.

Published: November 2024

The Synthetic Corona Outflow Model (SynCOM), an empirical model, simulates the solar corona’s dynamics to match high-resolution observations, providing a useful resource for testing velocity measurement algorithms. SynCOM generates synthetic images depicting radial variability in total brightness and includes stochastic elements for plasma outflows and instrumental noise. It employs a predefined probability distribution for flow velocity and an adjustable signal-to-noise ratio to evaluate different data analysis methods for coronal flows. By adjusting parameters to match specific coronal and instrumental conditions, SynCOM offers a platform to assess these methods for determining coronal velocity and acceleration. Validating these measurements would help us to understand the origins of the solar wind and support missions such as the Polarimeter to Unify the Corona and Heliosphere (PUNCH). In this study, we demonstrate how SynCOM can be employed to assess the precision and performance of two different flow-tracking methods. By providing a ground truth based on observational data, we highlight the importance of SynCOM in confirming observational standards for detecting coronal flows.

We show with Gaia XP spectroscopy that extremely metal-rich (EMR) stars in the Milky Way ([M/H]XP ≳ 0.5) are largely confined to a tight “knot” at the center of the Galaxy. This EMR knot is round in projection, has a fairly abrupt edge near R
GC,proj ∼ 1.5 kpc, and is a dynamically hot system. This central knot also contains very metal-rich (VMR; +0.2 ≤ [M/H]XP ≤ +0.4) stars. However, in contrast to EMR stars, the bulk of VMR stars forms an extended, highly flattened distribution in the inner Galaxy (R
GC ≲ 5 kpc). We draw on TNG50 simulations of Milky Way analogs for context and find that compact, metal-rich knots confined to ≲1.5 kpc are a universal feature. In typical simulated analogs, the top 5%–10% most metal-rich stars are confined to a central knot; however, in our Milky Way data this fraction is only 0.1%. Dust-penetrating wide-area near-infrared spectroscopy, such as the fifth Sloan Digital Sky Survey, will be needed for a rigorous estimate of the fraction of stars in the Galactic EMR knot. Why in our Milky Way only EMR giants are confined to such a central knot remains to be explained. Remarkably, the central few kiloparsecs of the Milky Way harbor both the highest concentration of metal-poor stars (the “poor old heart”) and almost all EMR stars. This highlights the stellar population diversity at the bottom of galactic potential wells.
Translational Tomography with the Wide-field Imager for Parker Solar Probe (WISPR). II. Refinements to the Method

Published: November 2024

We present progress on the translational tomography technique for measuring the three-dimensional structure of the corona from near-perihelion Wide-field Imager for Parker Solar Probe (WISPR) image sequences. Translational tomography makes use of noncircular motion of a camera to extract three-dimensional information from an optically thin subject. Parker Solar Probe (PSP) presents a special case both because of the particular structure of the corona and because of the nonlinear motion of the vantage point. We show improvements to a previous direct analytic method (described in Paper I of this series) and an alternative inversion pathway using a synthetic sequence of WISPR images. The newer method successfully reconstructs the correct locations of modeled coronal rays in a synthetic WISPR image sequence, with curvilinear camera motion modeled on the PSP orbit. We present the refined methodology and validation study, and show that the technique is ready for application to actual WISPR data.
On Velocity Stopbands in Electrostatic Solitary Wave Propagation in Magnetospheric Plasma in the Presence of an Ion Beam—Application in the Solar Wind

Published: November 2024

Satellite observations in the Earth’s magnetosphere suggest a coexistence of different types of ion populations, such as protons and heavier helium ions (alpha particles) transported by the solar wind. We have undertaken an investigation, from first principles, of the conditions for the occurrence of electrostatic solitary waves in such a multi-ion plasma environment. Nonlinear analysis has been employed to explore the effect of an ion beam on the occurrence of stopbands in a multicomponent plasma consisting of Boltzmann electrons and two ion species, modeled as cold and warm (adiabatic) ions. A “stopband” is an interval of pulse speed (mach (Mach number) values in which solitary waves cannot propagate. Such stopbands are known to exist in relation to fast ion-acoustic solitary waves (exclusively). Our parametric analysis reveals that the stopband widens over the range of cold ion charge density (values) upon increasing speed of a hot ion beam moving along the direction of wave propagation. However, the stopband becomes narrower in the case of a counterpropagating beam. Similarly, the streaming of a cold ion beam fluid along (or antiparallel) to the wave direction leads to the narrowing (or widening, respectively) of the stopband. The fast soliton existence (velocity) domain is characterized by two critical points (a crossover and a turning point), which are affected by the beam. Our study could be relevant to understanding energy dissipation processes in the fast solar wind associated with relative drifts between the major (protons) and minor (alpha particles) ions which results in the heating of both species.
Detection of the Extended γ-Ray Emission from the New Supernova Remnant G321.3–3.9 with Fermi-LAT
Authors: Guo Xiaolei , Liu Xi
Published: November 2024

With the 15 yr of Pass 8 data recorded by the Fermi Large Area Telescope, we report the detection of an extended gigaelectronvolt emission component with a 68% containment radius of 0.°85, which is spatially associated with the newly identified supernova remnant (SNR) G321.3–3.9. The γ-ray spectrum is best described by a log-parabola model in the energy range of 100 MeV–1 TeV, which shows a significant spectral curvature at ∼1 GeV. Either a leptonic or a hadronic model could explain the multiwavelength data of G321.3–3.9, while the leptonic model predicts a too-low strength of magnetic field. Also considering the flat radio spectrum of G321.3–3.9 and the γ-ray upper limit in the low energy band, the hadronic model is favored. The spatial coincidence between the γ-ray morphology and the diffuse thermal X-ray emission of G321.3–3.9 and the curved gigaelectronvolt γ-ray spectrum make G321.3–3.9 similar to the typical middle-aged SNRs interacting with molecular clouds (MCs). Such characteristics provide further evidence of the potential hadronic origin for its γ-ray emission. However, there is no MC detected around G321.3–3.9, which challenges the hadronic model.
Well-balanced High-order Finite Difference Weighted Essentially Nonoscillatory Schemes for a First-order Z4 Formulation of the Einstein Field Equations

Published: November 2024

We develop a new class of high-order accurate well-balanced finite difference (FD) weighted essentially nonoscillatory (WENO) methods for numerical general relativity (GR), which can be applied to any first-order reduction of the Einstein field equations, even if nonconservative terms are present. We choose the first-order nonconservative Z4 formulation of the Einstein equations, which has a built-in cleaning procedure that accounts for the Einstein constraints and that has already shown its ability in keeping stationary solutions stable over long timescales. By introducing auxiliary variables, the vacuum Einstein equations in first-order form constitute a partial differential equation system of 54 equations that is naturally nonconservative. We show how to design FD-WENO schemes that can handle nonconservative products. Different variants of FD WENO are discussed, with an eye to their suitability for higher-order accurate formulations for numerical GR. We successfully solve a set of fundamental tests of numerical GR with up to ninth-order spatial accuracy. Due to their intrinsic robustness, flexibility, and ease of implementation, FD-WENO schemes can effectively replace traditional central finite differencing in any first-order formulation of the Einstein field equations, without any artificial viscosity. When used in combination with well-balancing, the new numerical schemes preserve stationary equilibrium solutions of the Einstein equations exactly. This is particularly relevant in view of the numerical study of the quasi-normal modes of oscillations of relevant astrophysical sources. In conclusion, general relativistic high-energy astrophysics could benefit from this new class of numerical schemes and the ecosystem of desirable capabilities built around them.
