Published: February 2025

Penelitian ini bertujuan untuk menganalisis tingkat kebugaran jasmani dan Indeks Massa Tubuh (IMT) siswa yang tinggal di wilayah pesisir dan perkotaan di Kabupaten Tulungagung. Metode penelitian yang digunakan adalah pendekatan kuantitatif dengan desain komparatif, melibatkan 208 siswa dari MTsN 1 (perkotaan) dan MTsN 4 (pesisir) sebagai sampel. Instrumen penelitian mencakup tes kebugaran (Pacer Test), pengukuran tinggi dan berat badan, serta kuesioner aktivitas fisik dan kualitas hidup. Hasil analisis menunjukkan bahwa tidak terdapat perbedaan signifikan dalam IMT antara siswa di kedua wilayah (p = 0,420). Namun, terdapat perbedaan signifikan dalam kebugaran jasmani (VO2Max) dengan nilai p 0,001, di mana siswa di wilayah perkotaan menunjukkan tingkat kebugaran yang lebih baik dibandingkan siswa di wilayah pesisir. Faktor lingkungan, akses terhadap fasilitas olahraga, serta kebiasaan aktivitas fisik diduga berkontribusi terhadap perbedaan ini. Selain itu, terdapat hubungan signifikan antara kebugaran jasmani dengan aktivitas fisik (r = 0,380, p 0,001) serta kualitas hidup dengan IMT (r = 0,200, p = 0,047), yang menunjukkan bahwa pola hidup aktif dan kualitas hidup yang baik dapat berperan dalam meningkatkan kebugaran jasmani dan mengelola berat badan. Temuan ini menekankan pentingnya promosi aktivitas fisik yang lebih luas serta penyediaan fasilitas olahraga yang merata untuk meningkatkan kebugaran jasmani siswa di berbagai lingkungan.

Metode kuantitatif komparatif dengan pendekatan cross-sectional digunakan, melibatkan 30 atlet sepak bola berusia 12-17 tahun. Data dikumpulkan menggunakan Leadership Scale for Sport (LSS) untuk mengukur persepsi atlet terhadap kepemimpinan pelatih dan Coach-Athlete Relationship Questionnaire (CART-Q) untuk menilai kualitas hubungan pelatih-atlet. Analisis data dilakukan dengan independent sample t-test dan one-way ANOVA menggunakan SPSS 24. Hasil penelitian menunjukkan bahwa terdapat perbedaan signifikan antara gaya kepemimpinan demokratis dan otoriter terhadap kompatibilitas hubungan pelatih-atlet (p 0,05). Kepemimpinan demokratis memiliki nilai rata-rata hubungan pelatih-atlet yang lebih baik dibandingkan kepemimpinan otoriter (MD=4.824). Namun, tidak ditemukan perbedaan yang signifikan dalam hubungan pelatih-atlet berdasarkan posisi bermain atlet (p 0,05). Studi ini memberikan wawasan bagi pelatih dalam mengadopsi gaya kepemimpinan yang lebih inklusif untuk meningkatkan hubungan dengan atlet dan mendukung perkembangan mereka dalam olahraga.
Prediction of drug exposure in hepatic impairment: a comparison between minimal physiologically based pharmacokinetic (mPBPK) and whole body PBPK models
Authors: Mahmood Iftekhar
Published: February 2025

Aim: The objective of this study was to develop a minimal physiologically based pharmacokinetic (mPBPK) model to predict area under the curve (AUC) and maximum plasma concentration (Cmax) of drugs in subjects with varying degrees of hepatic impairment and compare this mPBPK model with the whole body PBPK model.
Methods: Hepatic impairment classification system, which is based on Child-Pugh score was used. In this mPBPK model, 4 physiological parameters [portal and renal blood flow, glomerular filtration rate (GFR), and liver size] and 2 biochemical parameters (albumin and bilirubin) were used. Total number of drugs analyzed in this study was 52, and the predicted Cmax and AUC values were compared with dedicated clinical trials. Out of 52 drugs, the predictive performance of mPBPK was compared with the whole body PBPK model for 27 drugs, and the remaining 25 drugs were used to further test the robustness of the mPBPK model.
Results: The results of the study indicated that the predictive performance of the mPBPK model was comparable with the whole body PBPK model, both in terms of Cmax and AUC. For 52 drugs, there were 120 data points for AUC (37, 47, and 36 for mild, moderate, and severe hepatic impairment, respectively), and from mPBPK model, 92%, 94%, and 89% data points were within 0.5–2-fold prediction error, respectively.
Conclusions: Overall, the results of the study indicated that the proposed mPBPK model, in its predictive performance, is as robust and accurate as whole body PBPK model.

The Animal-AI Environment is a unique game-based research platform designed to facilitate collaboration between the artificial intelligence and comparative cognition research communities. In this paper, we present the latest version of the Animal-AI Environment, outlining several major features that make the game more engaging for humans and more complex for AI systems. These features include interactive buttons, reward dispensers, and player notifications, as well as an overhaul of the environment’s graphics and processing for significant improvements in agent training time and quality of the human player experience. We provide detailed guidance on how to build computational and behavioural experiments with the Animal-AI Environment. We present results from a series of agents, including the state-of-the-art deep reinforcement learning agent Dreamer-v3, on newly designed tests and the Animal-AI testbed of 900 tasks inspired by research in the field of comparative cognition. The Animal-AI Environment offers a new approach for modelling cognition in humans and non-human animals, and for building biologically inspired artificial intelligence.
STUDI KOMPARATIF KONSEP SUNAT DALAM PERJANJIAN LAMA DAN PERJANJIAN BARU
Authors: Paillin Wiranto Bongga
Published: February 2025

Artikel ini membandingkan konsep Sunat menurut teks Perjanjian Lama dan gagasan Sunat menurut teks Perjanjian Baru. Dalam hal ini akan dibandingkan konsep sunat pada kedua teks yang ada, kemudian memberikan pemahaman mengenai implikasi sunat dalam kehidupan umat Kristiani masa kini. Penulis menggunakan metode penelitian kualitatif dan pendekatan deskriptif serta studi literatur. Kemudian, penulis menemukan bahwa sunat mempunyai arti 2 hal, yaitu “sunat luar” dan “sunat dalam”. Dalam hal ini yang dimaksud dengan “sunat luar” adalah sunat yang menekankan praktek sunat secara harafiah, yaitu memotong kulup laki-laki. Kemudian, “Sunat Batin” adalah sunat yang menekankan pada “penyunatan hati”, yakni memotong kulup jantung. Dalam hal ini yang dimaksud dengan “sunat hati” adalah meninggalkan kehidupan lama dengan perbuatan yang tidak sesuai dengan kehendak Tuhan, dan menuju kehidupan baru dengan perbuatan yang sesuai dengan kehendak Tuhan. Melalui hal tersebut, sunat mempunyai makna yang sangat mendalam bagi kehidupan umat Kristiani saat ini, agar mereka dapat menatap kehidupannya ke arah pertobatan yang sejati.
LEITURAS DA CIDADE: DIÁLOGOS ENTRE EXISTÊNCIAS E POSSIBILIDADES
Authors: COLUCCI D.
Published: February 2025

Pensar a cidade hoje passa pela compreensão de que sua complexidade exige que os saberes sobre ela abarquem a multiplicidade de experiências e leituras que nela se constroem. Por outro lado, para que isso seja possível, sem que haja sobreposição do conhecimento dos experts aos outros saberes, é fundamental gestar lugares de encontros onde possam ser travados múltiplos diálogos entre os diversos sujeitos que experienciam a cidade e, a partir desta vivência, elaboram as suas leituras, seus saberes e suas utopias.
ENTRE SUCESSÕES E COEXISTÊNCIAS: a empiricização do Tempo e a Técnica na Produção do Espaço
Authors: Ribeiro Marcos Vinícius de Andrade
Published: February 2025

O presente artigo propõe um debate sobre o espaço geográfico com base nas contribuições de Milton Santos (1996). Como objetivo geral, busca-se analisar a relação entre o tempo e as técnicas na produção do espaço geográfico. De forma mais específica, pretende-se discutir a empiricização do tempo na perspectiva miltoniana, além de compreender o papel das técnicas na produção do espaço. Para alcançar esses objetivos, foram realizados levantamentos bibliográficos e pesquisas relacionadas à epistemologia da geografia. Em seguida, analisaram-se as concepções presentes na obra A Natureza do Espaço: tempo e técnica, razão e emoção, bem como em outros textos de Milton Santos que fundamentam essa produção. Os resultados indicam que o enfoque nas técnicas oferece à geografia a oportunidade de compreender os mecanismos de produção e (re)produção do espaço geográfico. Observa-se que as características da sociedade e do espaço estão intimamente ligadas a determinados estados das técnicas. Compreender os sistemas técnicos sucessivos é essencial para entender as diferentes formas históricas de estruturação, funcionamento e articulação do tempo, especialmente na contemporaneidade. Conclui-se que o tempo é inseparável do espaço e, para adquirir concretude, deve ser necessariamente empiricizado. Ressalta-se, ainda, que, em cada lugar geográfico, existe, a cada momento, um conjunto de técnicas, instrumentos de trabalho e formas organizacionais, resultado de uma combinação específica, historicamente determinada.

O estudo aborda a relação entre racismo e violência obstétrica, destacando como o racismo estrutural intensifica desigualdades na saúde das mulheres negras. Baseando-se em uma revisão narrativa de literatura de 2017 a 2024, foram analisados artigos de bases como SciELO e PubMed. A violência obstétrica, definida por práticas desumanas e negligentes, afeta desproporcionalmente mulheres negras devido a desigualdades de acesso, racismo institucional e discriminação racial no ciclo gravídico-puerperal. Essas mulheres enfrentam maior risco de intervenções invasivas, falta de anestesia e atendimento desrespeitoso, resultando em impactos físicos, emocionais e sociais. O estudo também explora como o racismo estrutural influencia práticas médicas e políticas de saúde, agravando disparidades raciais em mortalidade materna, morbidade e assistência pré-natal. Iniciativas como a Rede Cegonha no Brasil e movimentos pelo parto humanizado buscam minimizar essas desigualdades, mas enfrentam desafios como a ausência de legislação específica. Conclui-se que o racismo é um fator determinante nas disparidades de saúde materna, reforçando a urgência de políticas públicas inclusivas, formação de profissionais de saúde conscientes e garantia de direitos reprodutivos para combater a violência obstétrica e promover equidade no atendimento às mulheres negras.

A educação inclusiva, reconhecida como direito desde a Declaração de Salamanca, demanda adequações que respeitem a diversidade em todos os níveis de ensino. Este estudo aborda a criação de um material concreto para o ensino de lógica matemática a alunos com deficiência visual no ensino superior. O material inclui pinos e duas apostilas, uma em linguagem convencional e outra em Braille, promovendo acessibilidade e inclusão. A pesquisa descreve o processo de desenvolvimento do material, desde sua concepção até a prototipação. Os resultados já incluem as primeiras versões das apostilas e protótipos dos pinos, contendo conectivos lógicos, proposições e operações fundamentais da lógica. Como continuidade, planeja-se validar o material com usuários finais, destacando a importância de recursos palpáveis que possibilitam a concretização de conectivos lógicos, construção de tabelas verdade e outros tópicos de lógica matemática, de forma similar ao trabalho feito em quadros ou cadernos, mas adaptados à percepção tátil. Esses recursos podem facilitar o entendimento dos conteúdos, contribuindo para uma educação mais acessível e de qualidade. Apesar dos avanços, há desafios significativos a serem superados, incluindo questões pedagógicas, financiamento de iniciativas inclusivas e desenvolvimento de tecnologias acessíveis. Contudo, este estudo estabelece uma base sólida para o progresso, destacando a relevância de estratégias eficazes e a conscientização sobre a inclusão no ensino de matemática. A busca por equidade e acessibilidade na educação permanece um objetivo essencial, contemplando estudantes com diferentes tipos de deficiências e transtornos globais do desenvolvimento.

Atualmente encontra-se estudantes desinteressados e desmotivados pelo estudo, isso acontece muitas das vezes pela forma como o ensino acontece, por meio de métodos convencionais, que não atraem a atenção dos alunos. Pensando nisso, as tecnologias podem ser uma alternativa viável e benéfica para auxiliar neste problema. A gameficação é uma tecnologia dentre as várias existentes, que podem potencializar o processo de ensino e aprendizagem, além de motivar os alunos a participarem das aulas. Nesse viés, este estudo objetivou analisar a importância da gamificação no processo de ensino-aprendizagem, destacando seus benefícios para o engajamento e motivação dos alunos, e discutir os principais desafios enfrentados na sua implementação eficaz nas instituições educacionais. Para tornar isso possível, desenvolveu-se um estudo bibliográfico do tipo revisão narrativa da literatura, com uso da análise de livre interpretação para analisar os dados encontrados. Como resultados, observa-se que a gamificação utiliza elementos dos jogos para promover o aprendizado de estudantes. Sua aplicação em sala de aula aumenta o engajamento, a motivação e o desenvolvimento de habilidades dos estudantes. Embora ofereça benefícios como personalização do ensino e aprimoramento de habilidades, entre outros, sua implementação enfrenta desafios, como a adaptação dos educadores, a resistência à mudança e a falta de infraestrutura tecnológica. Por fim, considera-se que a gamificação se apresenta como uma metodologia inovadora e promissora no processo de ensino-aprendizagem.

Published: February 2025

Due to its ever-growing population, Brebes had the biggest population in Central Java from 2020 to 2022. The government of Brebes has to predict the growth rate of the population and prepare the resources and employment opportunities to anticipate this population growth rate. This research aims to analyze the result of growth rate prediction in Brebes using Multilayer Perceptron (MLP) and Recurrent Neural Network (RNN). These two methods are applied to determine the most suitable one to predict the population growth rate. This is determined by comparing the smallest MAPE value of these two methods. The analyzed data of the total population from 1991-2022 is taken from Badan Pusat Statistik (BPS) of Brebes. The percentage of division between training and testing data is 80%:20%. According to the research results, the recurrent neural network is the most suitable method, with the smallest MAPE being 1.9973%.

Published: February 2025

Forecasting is an activity that predicts future values {}{}by utilizing existing track record data. The object of this study is rice plants because they are the primary food source for the Indonesian people. Every year, the Government strives for rice farmers throughout Indonesia to produce abundant rice harvests to meet the community's food needs. Therefore, rice farmers need a system that can predict their rice harvests to obtain information about future harvests to find out whether their harvests have decreased or increased so that they can determine efforts that can be made in the future and can be used as a policy maker for the Government in maintaining the national food security chain. This study uses time series data on rice harvests in Pamekasan, Madura, for 2007-2023 using the Support Vector Regression (SVR) model. The results of several trials have shown that the application of the SVR model for forecasting rice harvests in 2024 has produced good accuracy with a relatively low MAPE error rate of 3.97\%, and the rice harvest has reached an average prediction of 15470.08 tons with an average actual data of 7937.884 tons. Therefore, applying this SVR model can be recommended for predicting future rice harvests.
Performance of Sparse Code Multiple Access Communication System Based on Logarithmic Message Passing Algorithm and Low-Density Parity Check Code
Authors: Safwan Moafaq Mustafa , K. Mahmood Al-Azawi Maher
Published: February 2025

The performance of Sparse Code Multiple Access (SCMA) communication system with Logarithmic Message Passing Algorithm (log-MPA) decoder is introduced. To boost the performance, a Low-Density Parity-Check Code LDPC is used together with Belief Propagation (BP) decoder. LDPC is chosen due to its sparsity property that complements the sparsity nature of SCMA for maximum efficiency and minimum complexity. Three distinct SCMA configurations are used. These are: A (4 x 4 x 6), B (4 x 16 x 6), and C (5 x 4 x 10) where the (K x M x V) are numbers of resources, codewords and users respectively. The performance of these configuration is shown in various channel conditions, various LDPC code rates and various numbers of SCMA iterations (N_SCMA), to find the local minimum value of log-MPA. Simulation results showed that the LDPC greatly boosted the performance in mentioned configurations: In A configuration, a gain of 13 dB was observed. Configuration B experienced a substantial improvement of 23.5 dB, while C achieved a gain of 20.5 dB. Notably, configuration B stood out with the highest gain, attributed to LDPC's exceptional performance with high data rates, as the data transmitted in B was double that of A.

Published: February 2025

Across Canada, many efforts have been put towards increasing physician engagement to bridge communication and collaboration between physicians and administrative leadership. One measure was the Facility Engagement Initiative (FEI) created in 2016 by Doctors of BC and the BC Ministry of Health, which has provided funding to over 70 provincial engagement groups. While many projects have been supported, there is no systematic approach or established tool to describe and evaluate these initiatives. This study presents a method of characterizing and evaluating physician engagement initiatives using projects funded by FEI through one medical society, the BC Cancer Medical Staff Engagement Society (MSES).

In this fourth article in a series on health economics, we focus on cost minimization analysis to clarify how its results should be interpreted. Cost minimization analysis is contraindicated if the options under consideration differ in an important attribute besides cost. The benefits of cost minimization analysis mostly stem from leaders considering the method’s shortcomings.
Inmigración y educación en Chile: explorando los efectos en el rendimiento y la segregación escolar
Authors: Eyzaguirre Sylvia , Guzmán Isaí
Published: February 2025

La inmigración en Chile ha crecido de forma exponencial en la última década. La literatura internacional nos advierte sobre even- tuales conflictos sociales y efectos no deseados en el ámbito escolar. Los próximos dos años estarán marcados en nuestro país por las elec- ciones municipales, regionales, parlamentarias y presidenciales, y sin duda la inmigración será uno de los temas que marcará la agenda. Este artículo tiene por objeto estudiar el efecto del aumento de la matrícula de inmigrantes en el rendimiento académico de los estudiantes y en la segregación escolar en Chile. Con ello buscamos contribuir al debate aportando evidencia que permita visibilizar los incipientes problemas que pueden estar surgiendo, así como también los eventuales prejuicios. Para ello, utilizamos los registros de matrícula y los resultados del Sistema de Admisión Escolar del Ministerio de Educación, el Índice de Vulnerabilidad Educacional de la Junaeb, y los resultados de las pruebas como la información que proporcionan los cuestionarios del Simce de la Agencia de Calidad de la Educación. A través de una estrategia de diferencias en diferencias, observamos un efecto heterogéneo en el rendimiento académico de los estudiantes chilenos. A mayor tasa de matrícula de inmigrantes, se observa un importante efecto negativo en matemática, pero positivo en lectura para los compañeros chilenos de colegio. En el rendimiento académico de los propios inmigrantes no se observa un efecto significativo. Los resultados en segregación, obtenidos a través de una estrategia de shift share (Ali 2021), muestran que una mayor proporción de estudiantes inmigrantes tiene un efecto negativo en la matrícula total del establecimiento, que podía ser un indicio de native flight. Además, encontramos que un aumento de la proporción de escolares inmigrantes en un colegio afecta de forma negativa las postulaciones totales y de primera preferencia de los estudiantes chilenos a ese colegio.

The 2024 conference of the China Society of Indexers (CSI) was held at Peking University in Beijing, China, from 24 to 26 October 2024. It was attended by five international delegates and nearly 150 Chinese delegates; this account of the conference is written from the perspective of the international delegates. The theme of the conference was artificial intelligence (AI) and indexing. Speakers explored applications of AI and indexing in broad contexts, including science, technology, innovation measurement and economic development, while back-of-book indexing took a back seat.

We present a MIRI-MRS spectrum of the high-inclination protoplanetary disk around the solar-mass (K0) star MY Lup, obtained as part of the JWST Disk Infrared Spectral Chemistry Survey (JDISCS). The spectrum shows an unusually weak water emission spectrum for a disk around a star of its spectral type, but strong emission from CO2, HCN, and isotopologues of both molecules. This includes the first ever detection of C18O16O and H13CN in an inner disk, as well as tentative detections of C17O16O and HC15N. Slab modeling provides the molecular temperatures, column densities, and emitting areas of the detected molecules. The emitting molecular gas is cold compared to that of other observed protoplanetary disk spectra. We estimate the isotopologue ratios of CO2 and HCN, albeit with significant uncertainty. We suggest that the unusual spectrum of MY Lup arises from a combination of inner-disk clearing, which removes emission from warm water, and its nearly edge-on inclination, which enhances line-of-sight column densities, although unusual chemistry may also be required. MY Lup’s spectrum highlights the potential to detect and measure trace isotopologues to study isotopic fractionation in protoplanetary disks; observations at higher spectral resolving power are needed to constrain the isotopologue ratios to greater precision.

New observations obtained with JWST of the protostellar HH 270 jet and the “deflected” HH 110 system show that HH 110 has a morphology of a series of distorted working surfaces. These working surfaces appear to be “deflected versions” of the heads of the incident HH 270 jet. We compute a series of 3D numerical simulations, in which we explore the possible parameters of a shearing environment that could give rise to the deflection of HH 270 into the HH 110 flow. We find that we need quite a high sideways velocity for the streaming environment (∼30 km s−1) in order to produce the complex structure observed in HH 110. This high velocity would be possible in an environment that has been strongly perturbed by the passage of other outflows.
On the Temporal Variability of the Galactic Multi-TeV Interstellar Emissions

We use the GALPROP cosmic ray (CR) framework to model the Galactic CR distributions and associated nonthermal diffuse emissions up to PeV energies. We consider ensembles of discrete, finite lifetime CR sources, e.g., supernova remnants, for a range of creation rates and lifetimes. We find that the global properties of the CR sources are likely not directly recoverable from the current “snapshot” of the historic injection and propagation of CRs within the Galaxy that are provided by the data. We show that models for the diffuse γ rays based on the discrete/time-dependent scenarios we consider are able to explain the LHAASO very-/ultra-high-energy (VHE/UHE) γ-ray data with up to 50% contribution by unresolved leptonic sources at the highest energies. Over the models that we consider, variations in the diffuse VHE emissions can be ∼25%, which is comparable to those for the steady-state models that we investigated in an earlier work. Such variations due to the discrete/finite nature of the CR sources are an important factor that are necessary to construct accurate physical models of the diffuse emissions from the Galaxy at VHE/UHEs.
LIMFAST. III. Timing Cosmic Reionization with the 21 cm and Near-infrared Backgrounds

The timeline of cosmic reionization remains uncertain despite sustained efforts to study how the ionizing output of early galaxies shaped the intergalactic medium (IGM). Using the seminumerical code LIMFAST, we investigate the prospects for timing the reionization process by cross-correlating the 21 cm signal with the cosmic near-infrared background (NIRB) contributed by galaxies at z > 5. Tracing opposite phases of the IGM on large scales during reionization, the two signals together serve as a powerful probe for the reionization history. However, because long-wavelength, line-of-sight Fourier modes—the only modes probed by NIRB fluctuations—are contaminated by 21 cm foregrounds and thus inevitably lost to foreground cleaning or avoidance, a direct cross correlation of the two signals vanishes. We show that this problem can be circumvented by squaring the foreground-filtered 21 cm signal and cross-correlating the squared field with the NIRB. This statistic is related to the 21 cm–21 cm–NIRB cross bispectrum and encodes valuable information regarding the reionization timeline. Particularly, the 21 cm2 and NIRB signals are positively correlated during the early phases of reionization and negatively correlated at later stages. We demonstrate that this behavior is generic across several different reionization models and compare our simulated results with perturbative calculations. We show that this cross correlation can be detected at high significance by forthcoming 21 cm and NIRB surveys such as the Square Kilometre Array and SPHEREx. Our methodology is more broadly applicable to cross correlations between line intensity mapping data and 2D tracers of the large-scale structure, including photometric galaxy surveys and cosmic microwave background lensing mass maps, among others.
A Central TDE Candidate Detected through Spectroscopic Continuum Emission Properties in an SDSS Blue Quasar
Authors: Zhang XueGuang
Published: February 2025

In this paper, properties of spectroscopic continuum emissions are considered to detect potential tidal disruption event (TDE) candidates among Sloan Digital Sky Survey (SDSS) quasars. After considering the simple blackbody photosphere model applied to describe quasar continuum emissions with parameters of blackbody temperature T

BB on T
BB for SDSS quasars, 402 outliers in the SDSS Stripe 82 region can be collected. Among the 402 outliers, SDSS J2308 at z = 1.16 is mainly considered, due to its SDSS spectrum observed around the peak brightness of the light curves. With the 7.2 yr long light curves described by the theoretical TDE model, the determined T
BB and R
BB through its spectroscopic continuum emissions are consistent with the values determined by the TDE model, to support the central TDE. Moreover, considering simulated results on continuum emissions of SDSS quasars around z ∼ 1.16, it can be confirmed at a confidence level higher than 4σ that the continuum emissions of SDSS J2308 are not related to normal quasars. Furthermore, through the simulated results by the accepted continuous autoregressive process to trace intrinsic active galactic nucleus variability, the confidence level higher than 3σ can be confirmed that the long-term light curves of SDSS J2308 are related to a central TDE. The jointed probabilities through both spectroscopic and photometric simulations, the confidence level higher than 5σ can be confirmed to support the central TDE in SDSS J2308.

Stream interaction regions (SIRs) are long-lasting solar wind structures that result from stable fast solar wind interacting with preceding slow solar wind. These structures have been examined in depth throughout the heliosphere, particularly at 1 au; however, due to sparse observations, SIRs have not been characterized thoroughly at 1.5 au. Thanks to the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we have a chance to fill this observational gap. We implement in situ solar wind data collected by MAVEN to identify SIRs between 2014 November and 2023 September. We observe 185 SIRs with average durations of 2.2 days that occur primarily during periods of low solar activity. We detect 19 forward shocks, seven reverse shocks, and one shock pair within these 185 SIRs. We predict a total SIR-associated shock detection rate of ∼56% at 1.5 au and compare this rate to previous findings spanning 0.1–5 au. We examine Solar Terrestrial Relations Observatory (STEREO) A data at 1 au to cross-compare with our results at 1.5 au. We determine the magnetic compression ratios (H) associated with SIRs at MAVEN and STEREO-A and find that H is ∼18% higher at 1.5 au than 1 au. We find that for a given SIR observed at both 1 and 1.5 au, H is ∼32% higher at 1.5 au. We also do not see a stark difference in the change in H for SIRs observed at both STEREO-A and MAVEN with respect to the angular separation of the spacecraft.
Neutrinos from Carbon-burning Red Supergiants and Their Detectability

Stars emit megaelectronvolt neutrinos during their evolution via nuclear syntheses and thermal processes, and detecting them could provide insights into stellar structure beyond what is accessible through electromagnetic wave observations. So far, megaelectronvolt neutrinos have been observed from the Sun and SN 1987A. It has been suggested that pre-supernova stars in the oxygen- and silicon-burning stages would emit enough megaelectronvolt neutrinos to be detectable on Earth, provided they are in the local Universe. In this study, we investigate the prospect of detecting neutrinos from red supergiants (RSGs) in the carbon-burning phase. In our Galaxy, around a thousand RSGs have been cataloged, and several are expected to be in the carbon-burning phase. We first calculate the luminosity and energy spectrum of the neutrinos emitted during the post-main-sequence evolution of massive stars. For a nearby carbon-burning RSG located  ∼200 pc away, we estimate the neutrino flux reaching Earth to be as large as  ∼105 cm−2 s−1, with a spectrum peaking at ∼0.6 MeV. We then assess the feasibility of detecting these neutrinos in underground facilities, particularly in hybrid detectors equipped with a water-based liquid scintillator and ultrafast photodetectors. In detectors with a volume comparable to Super-Kamiokande, for the above flux, we anticipate up to  ∼50 neutrino events per year with directional information. Although this is a fair number, the number of events from radioactive backgrounds would be much larger. Our results indicate that studying neutrinos from carbon-burning RSGs and predicting supernovae well in advance before their explosion would be challenging with currently available detector technologies.
Parallel Electric Fields and Electron Heating Observed in the Young Solar Wind
Authors: Mozer F. S. , Agapitov O. V. , Choi K.-E. , Sydora R. D.
Published: February 2025

The largest electric fields between 18 and 30 solar radii are in narrowband waves simultaneously observed at a few Hz (somewhat above the local proton gyrofrequency) and a few hundred Hz (far below the lower hybrid frequency), with the higher-frequency wave triggered at specific phases of the lower-frequency wave. This wave pair, called “triggered ion-acoustic waves” (TIAWs), has been shown to both be physical and to occur at times of electron heating. A theory of electron heating and acceleration by the low-frequency wave has been presented. While this theory and the TIAW results strongly suggest the presence of low-frequency electric fields that are parallel to the local magnetic field, such fields have not been directly observed. In this paper, such parallel electric field observations are reported, and TIAWs are further described to conclude that they occur during about 75% of the Parker Solar Probe passes through 18–30 solar radii, and when present, they are the dominant wave signal, lasting for hours. In the presence of these parallel electric fields, electrons are heated while, in their absence, there is no electron heating. That there is no heating between 18 and 30 solar radii in the absence of TIAWs is a most significant result because it invalidates other proposed mechanisms that predict heating in this radial range all of the time.
Coptic texts and Arabic-Christian intellectual history in Medieval Iberia
Authors: Burman Thomas E.
Published: February 2025

The essay that follows is an attempt to think about the circulation of Arabic books and ideas and to reflect on what the introduction of Copto-Arabic texts in the Iberian Peninsula means for the understanding of the intellectual history of the Andalusī Christians, of scholars such as Ramon Martí who lived primarily in the Latin-Christian intellectual orbit, but knew Arabic well and read widely in Arabic texts, and of the possible interconnections between them.
