Estrategia Contextual Musical para Incrementar el rendimiento Académico y la Afectividad en la Enseñanza y Aprendizaje de Español como Lengua Extranjera
Authors: Angulo-VanderSchaaf Victoria Patricia , Márquez Casero M. Victoria 
Published: January 2025

La investigación tuvo como propósito principal diseñar una estrategia musical contextual basada en canciones para mejorar tanto el desempeño académico como la afectividad en las clases de español como lengua extranjera en dos centros educativos de Minnesota. En la primera etapa participaron 40 docentes mediante una encuesta. En la segunda, se elaboró la estrategia musical contextual, y en la tercera se implementó la estrategia contextual musical siguiendo un diseño longitudinal pre-experimental estructurado como: G: P1 I P2. Para verificar las hipótesis, se utilizó la prueba de normalidad de Shapiro-Wilk con el software SPSS y, posteriormente, la Prueba T de Student para comparar los promedios de dos muestras relacionadas y evaluar diferencias significativas antes y después de la intervención. Las áreas abordadas incluyeron: gramática, vocabulario, comprensión auditiva y expresión oral. Los resultados evidenciaron diferencias significativas con ambas metodologías, destacando la gramática como la más beneficiada con el enfoque musical. Además, el componente afectivo fue fundamental para el éxito de la estrategia, como lo confirmó la entrevista a los estudiantes, quienes indicaron en un 100% que su motivación, interés, participación y satisfacción fueron mayores en las unidades trabajadas con la metodología musical, en comparación con las tradicionales, basadas en el libro de texto.

Authors: Cely Castro Rayniero Alberto 
Published: January 2025

El Síndrome de Alienación Parental comprende una conducta que se basa en la denigración, basada en el rechazo del niño, niña o adolescente hacia un padre, por la influencia negativa del otro padre o incluso de terceros. Como problemática del estudio se considera que en Ecuador el actual Código de la Niñez y Adolescencia no contempla la figura de la alienación parental, a pesar de que ésta es una conducta frecuente asociada a procesos de divorcios, que genera una vulneración de los derechos de los menores y del progenitor afectado. El objetivo del estudio es analizar la inclusión del Síndrome de Alienación Parental en el Código de la Niñez y Adolescencia, lo que se busca concretar a través de una reforma al citado código. El estudio presenta un enfoque cualitativo y bibliográfico, se utilizó la técnica del análisis documental para la identificación las propiedades y características generales de la alienación parental. Los resultados muestran el desarrollo de una amplia doctrina en el que se aborda el SAP y su afectación a la tenencia y al desarrollo integral de niños, niñas y adolescentes.
COST MINIMIZATION ANALYSIS OF ANTIHYPERTENSIVE DRUG USE IN CHRONIC KIDNEY DISEASE PATIENTS UNDERGOING HEMODIALYSIS
Authors: Utami Indah Kurnia , Rakanita Yasinta , Dewi Niluh Puspita 
Published: January 2025

Hypertension is the primary cause of Chronic Kidney Disease (CKD), as it damages blood vessels in the kidneys. The most commonly used management for hypertension as monotherapy includes Calcium Channel Blockers (CCB) such as Amlodipine and Angiotensin Receptor Blockers (ARB) such as candesartan. Patients with CKD undergoing hemodialysis depend on dialysis machines, which impacts their economic burden. Therefore, a cost analysis review of drugs with the same therapeutic goals is necessary. This was a non-experimental study with a descriptive design. Data were collected through retrospective purposive sampling from January to December 2023 using medical records and payment data for inpatient treatments with hemodialysis that met the inclusion criteria. Direct medical costs included antihypertensive, other medication, service and facility fees, and medical support costs. Of the 100 samples that met the inclusion criteria from January to December 2023, amlodipine was the most commonly used antihypertensive (56%), followed by candesartan (38%). The average direct medical costs were IDR 184.350 for Amlodipine and IDR 561,339 for candesartan. The patient characteristics by gender showed a higher percentage of males (52%) than of females (48%). By age, the majority were in the late adult group (67%), whereas the elderly accounted for (33%). The Amlodipine group achieved more significant cost minimization than the candesartan group. Future studies should examine the potential of amlodipine in reducing the economic burden of limited resources.

Giant Hall Waves Launched by Superconducting Phase Transition in Pulsars
Authors: Bransgrove Ashley , Levin Yuri , Beloborodov Andrei M. 
Published: January 2025

Abstract
The cores of pulsars are expected to become superconducting soon after birth. The transition to type-II superconductivity is associated with the bunching of magnetic field lines into discrete superconducting flux tubes which possess enormous tension. The coupling of the crust to the flux tubes implies the existence of huge tangential magnetic fields at the crust–core interface. We show that the transition to superconductivity triggers a highly nonlinear response in the Hall drift of the crustal magnetic field, an effect which was neglected in previous numerical modeling. We argue that at the time of the phase transition giant Hall waves are launched from the crust–core interface toward the surface. Our models show that if the crust contains a multipolar magnetic field ∼1013 G, the amplitude of the Hall waves is ∼1015 G. The elastic deformation of the lattice is included in our models, which allows us to track the time-dependent shear stresses everywhere in the crust. The simulations indicate that the Hall waves may be strong enough to break the crust, and could cause star quakes which trigger rotation glitches and changes in the radio pulse profile. The Hall waves also couple to slow magnetospheric changes, which cause anomalous braking indices. The emission of the giant Hall waves from the crust–core interface facilitates fast flux expulsion from the superconducting core, provided that the flux tubes in the core are themselves sufficiently mobile. For all of the flux tube mobility prescriptions implemented in this work, the core approaches the Meissner state with B = 0 at late times.

Published: January 2025

Abstract
Eclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium. This study investigates eclipses in 10 MSPs in compact orbit using wide-bandwidth observations with the Giant Metrewave Radio Telescope. We report the first evidence of eclipsing for PSR J2234+0944 and J2214+3000 in one epoch, while no evidence of eclipsing was observed in the subsequent two epochs, indicating temporal evolution of the eclipse cutoff frequency in these systems. Constraints on the eclipse cutoff frequency were obtained for PSR J1555–2908, J1810+1744, and J2051–0827. Moreover, for the first time, we detected an eclipse at a nonstandard orbital phase (∼0.5) for PSR J1810+1744, with a duration longer than the eclipse observed at superior conjunction. No eclipses were detected for PSR J0751+1807, J1738+0333, and J1807–2459A at 300–500 MHz and 550–750 MHz. We calculated the mass-loss rate of the companion for PSR J1555–2908 and PSR J1810+1744 and found that these rates are insufficient to ablate the companion stars. We cataloged the

, mass function, Roche lobe filling factor, and inclination angle for compact MSP binaries with low-mass companions and found that higher spin-down flux does not guarantee eclipses. Our analysis, supported by the Kolmogorov–Smirnov statistic, confirms that eclipsing black widow binaries generally exhibit a higher mass function compared to noneclipsing black widow binaries, consistent with previous studies.
Detecting Stellar Flares in Photometric Data Using Hidden Markov Models

Published: January 2025

Abstract
We present a hidden Markov model (HMM) for discovering stellar flares in light-curve data of stars. HMMs provide a framework to model time series data that are nonstationary; they allow for systems to be in different states at different times and consider the probabilities that describe the switching dynamics between states. In the context of the discovery of stellar flares, we exploit the HMM framework by allowing the light curve of a star to be in one of three states at any given time step: quiet, firing, or decaying. This three-state HMM formulation is designed to enable straightforward identification of stellar flares, their duration, and associated uncertainty. This is crucial for estimating the flare's energy, and is useful for studies of stellar flare energy distributions. We combine our HMM with a celerite model that accounts for quasiperiodic stellar oscillations. Through an injection recovery experiment, we demonstrate and evaluate the ability of our method to detect and characterize flares in stellar time series. We also show that the proposed HMM flags fainter and lower energy flares more easily than traditional sigma-clipping methods. Lastly, we visually demonstrate that simultaneously conducting detrending and flare detection can mitigate biased estimations arising in multistage modeling approaches. Thus, this method paves a new way to calculate stellar flare energy. We conclude with an example application to one star observed by TESS, showing how the HMM compares with sigma clipping when using real data.
Radial-dependent Responsivity of Broad-line Regions in Active Galactic Nuclei: Observational Consequences for Reverberation Mapping and Black Hole Mass Measurements
Authors: Li Yan-Rong , Wang Jian-Min 
Published: January 2025

Abstract
The reverberation mapping (RM) technique has seen wide applications in probing geometry and kinematics of broad-line regions (BLRs) and measuring masses of supermassive black holes (SMBHs) in active galactic nuclei. However, key quantities in RM analysis such as emissivity, responsivity, transfer functions, and mean and rms spectra are fragmentally defined in the literature and largely lack a unified formulation. Here we establish a rigorous framework for BLR RM and include a locally dependent responsivity according to photoionization calculations. The mean and rms spectra are analytically expressed with emissivity- and responsivity-weighted transfer functions, respectively. We demonstrate that the rms spectrum is proportional to the responsivity-weighted transfer function only when the continuum variation timescale is much longer than the typical extension in time delay of the BLR; otherwise, biases arise in the obtained rms line widths. The long-standing phenomenon pertaining to the different shapes between the mean and rms spectra can be explained by a radial-increasing responsivity of BLRs. The debate on the choice of emission-line widths for SMBH mass measurements is explored, and the virial factors are suggested to also depend on the luminosity states, in addition to the geometry and kinematics of BLRs.

Published: January 2025

Abstract
Young planetary nebulae (PNe) are characterized by their hot central stars and the presence of abundant neutral and molecular components, which result from significant mass loss during the asymptotic giant branch phase of stellar evolution. Far-UV He ii
λ1025 line photons produced near the central star can undergo Raman scattering by hydrogen atoms, creating a broad emission feature centered at ~6545 Å. We conducted high-resolution spectroscopy of 12 young PNe from 2019 April to 2020 March using the Bohyunsan Observatory Echelle Spectrograph. Building on the study by Choi and Lee, who identified Raman-scattered He ii at 6545 Å in NGC 6881 and NGC 6886, we report new detections of this feature in NGC 6741 and NGC 6884. Profile fitting reveals that the velocity of the H i component relative to the He ii emission region ranges from 26 to 33 km s−1 in these PNe. Using photoionization modeling, we estimate the line flux of He ii
λ1025 and derive Raman conversion efficiencies of 0.39, 0.21, 0.24, and 0.07 for NGC 6881, NGC 6741, NGC 6886, and NGC 6884, respectively. These results, combined with radiative transfer modeling, suggest the presence of H i components with masses around 10−2

Unusual Space Weathering on a CE-5 Metal Grain Indicates Deceptive Surface Signatures of M-type Asteroids

Published: January 2025

Abstract
M-type asteroids are historically thought to be exposed metallic cores of differentiated planets with a composition dominated by pure iron and nickel. However, recent spectral and radar observations reveal an insufficient number of M-type asteroids in the main belt. Here, we report unusual space weathering characteristics associated with a natural metal grain found in Chang'e 5 lunar soil. Microcraters, impact glass, iron whiskers, and unique vesicular rims on the surface of this grain help to explain the unusual properties of some potential M-type asteroids, including low thermal inertia and density. Our findings indicate that space weathering processes, including micrometeorite bombardment and solar wind irradiation, conceal the real surface signatures of M-type asteroids. Furthermore, the presence of He and Ge alloy on the metal grain suggests that M-type asteroids are not only a large metallic Fe and Ni reservoir but also a potential source of noble gases and precious metals.
Des interfaces traditionnelles hommes-machines aux machines empathiques : vers une coadaptation humain-machine
Authors: Devillers Laurence 
Published: January 2025

Le domaine de l’" affective computing " est par essence pluridisciplinaire, en regroupant trois technologies : la reconnaissance des émotions des humains, le raisonnement et la prise de décision en utilisant les informations recueillies, et la génération d’expressions émotionnelles. La sphère des émotions que l’on pouvait penser propre à l’humain envahit les machines qui se rapprochent des capacités humaines. Dans le cas de maltraitance d’un robot notamment, l’être humain peut ressentir de l’empathie envers un agent artificiel, alors que ce dernier ne fait que simuler des émotions et ne peut pas souffrir. La machine est programmée, sans intention ni désir propres, mais il faut le rappeler. L’arrivée des robots empathiques soulève depuis peu de nombreuses questions éthiques, juridiques et sociales.
De l’entre-lieu à la traduction comme lieu incontournable
Authors: Amaral Henrique Provinzano 
Published: January 2025

Cet article se propose d'analyser la pensée traductive de l'écrivain martiniquais Édouard Glissant - c'est-à-dire les textes qu’il a vraiment consacrés au débat théorique sur la traduction - à partir des paradigmes des idées d'« entre » et de « lieu ». Pour ce faire, il reprend des aspects de l'univers notionnel de Glissant, en particulier la notion de « lieu », qui constitue ce que l'on pourrait appeler un savoir non déclaratif sur la traduction, car il permet de penser des extensions et des prolongements théoriques de ce que Glissant a effectivement écrit sur ce sujet. En outre, l'article commente également certains aspects récents de la réflexion sur les concepts de lieu et de translation en traductologie, en revisitant des articles d'Álvaro Faleiros et de Leila Darin, avec en toile de fond la théorie d'Antoine Berman. L'objectif est d'avancer l'hypothèse que la pensée traductive de Glissant est liée à l'établissement et à la défense d'un « lieu incontournable », à partir duquel le traducteur accomplirait sa tâche : la translation des poétiques dans le contexte de la totalité-monde.
« L’Europe se créolise » – Créolisation et migration dans l’œuvre tardive d’Édouard Glissant face à la migration européenne actuelle
Authors: Kopf Martina 
Published: January 2025

Dans son œuvre tardive non fictive, Glissant se consacre de plus en plus à l’Europe et semble être toujours plus influencé par les thèmes politiques actuels qu’il analyse à l’aide de ses réflexions théoriques. La créolisation est ici principalement envisagée dans le contexte des mouvements migratoires et on trouve de nombreuses réflexions sur la migration, la nation, le racisme, l’identité et l’intégration. Cette contribution vise à mettre en évidence les idées de Glissant sur une Europe en migration et en créolisation. Après avoir esquissé les considérations théoriques de Glissant sur une Europe qui se créolise, il conviendra de se pencher sur l’interaction entre créolisation et migration dans un contexte politique européen. Dans ce contexte, la question se pose également de savoir quelle est la relation entre le (post)colonialisme et la migration. Même si le terme « migration » apparaît surtout dans l’œuvre tardive glissantienne, il semble déjà présent dans le concept de créolisation. En conclusion, il faudra également se demander dans quelle mesure la pensée de Glissant anticipe déjà des réponses à la migration actuelle en Europe telle que nous la vivons aujourd’hui. Il se révèle ainsi être un précurseur du courant de pensée actuel autour de la notion de postmigration.

Aim: This study assessed the role of rotational thromboelastometry (ROTEM)-guided transfusion protocol in reducing blood product transfusion during cardiac surgeries. Methodology: This randomized, single-blind trial enrolled 32 patients who were randomized to receive either the ROTEM-guided transfusion protocol or the classic transfusion protocol. The primary outcome was the need for blood component transfusion after bypass and during the initial 24 postoperative hours. Secondary outcomes included residual heparin after reversal with protamine and blood loss postoperatively during the first 24 hours. Results: While differences in red blood cell transfusions post-bypass and within the first 24 hours postoperatively were observed, they were statistically non-significant. Fresh frozen plasma (FFP) transfusions differed post-bypass, without statistical significance. However, the ROTEM group had a statistically significant reduction in FFP units within the first 24 hours postoperatively (P<0.001). The number of platelet units transfused in the initial 24 hours postoperatively showed a difference between both groups, but it was statistically non-significant. However, ROTEM significantly reduced platelet use post-bypass (P<0.001). Blood loss also differed between groups but was statistically non-significant. Conclusions: The application of ROTEM-guided transfusion protocol reduces blood product transfusion (FPP and platelets) in patients undergoing elective cardiac surgery on cardiopulmonary bypass.
Efficacy of Nalbuphine as An Adjunct to 0.5% Bupivacaine in Ultrasound- Guided Suprazygomatic Maxillary Nerve Block in Patients Undergoing Nasal and Maxillofacial Surgery &ndash; A Randomized Clinical Comparative Study
Authors: Sumalatha G. B. , Patel Sameera , Yadav Hemant , Dodawad Ravichandra 
Published: January 2025

Background & Aims: Ultrasound-guided suprazygomatic maxillary nerve block (MNB) is safe and efficacious in nasal and maxillofacial surgeries. The analgesic effect of nalbuphine is equal to that of morphine, with a ceiling effect on respiration. Therefore, this study aims to evaluate the efficacy of 0.2 mg/kg nalbuphine as an adjuvant to 0.5% bupivacaine compared to plain 0.5% bupivacaine in maxillary nerve block. Material & Methods: One hundred ASA I-II patients of either sex, scheduled for elective nasal and maxillofacial surgeries under general anesthesia, were randomly allocated into Group A and B (n=50) to receive USG-guided suprazygomatic MNB. Group A and Group B received 0.5% bupivacaine with 0.2 mg/kg of nalbuphine and 0.5% bupivacaine, respectively. The mean duration of analgesia, total consumption of opioids, and 24-hour postoperative side effects were recorded in both groups. The data were compared using Student's t-test, Chi-square test, and Mann–Whitney U test. P < 0.05 was considered statistically significant. Results: The mean duration of postoperative analgesia was significantly prolonged in the nalbuphine group (769.2 ± 117 vs. 559.2 ± 75 minutes; p = 0.002), with a significant reduction in the total consumption of nalbuphine (26.4 ± 5.06 vs. 52.77 ± 7.46 mg; p = 0.007) compared to the bupivacaine group. Conclusion: 0.2 mg/kg nalbuphine can be effective as an adjuvant to local anesthetics in MNB to prolong the postoperative duration of analgesia without significant side effects.

Published: January 2025

Background: Spontaneous hepatic rupture is a rare life-threatening event seen among patients with preeclampsia and HELLP syndrome bringing devastating outcomes to both the mother and the baby.Case presentation: We report a case of a 45-year-old sub fertile primigravida following an IVF treatment with donor embryo resulting in DCDA twin pregnancy.She was diagnosed with pregnancy induced hypertension at 20 weeks of period of gestation (POG) with DCDA twin pregnancy admitted at our hospital at 32 + 4 weeks of POG with headache, visual disturbances, vomiting and abdominal pain with severe pregnancy induced hypertension. Category I emergency cesarean section was performed due to eclampsia, suspected placental abruption with DCDA twins with single fetal demise and acute kidney injury. During caesarean section, right lobe of the liver rupture was diagnosed. Even with intense multidisciplinary management the life of this mother could not be saved leaving behind her newborn baby with the father.Conclusion: Due to the rarity of the entity, the unpredictable nature and the multisystemic involvement, many health care providers as well as pregnant women may not be aware of the fatal consequences of this complication.
