Authors: Mahata Intan B. E. , Utami Sri P. , Trisa Athifa 
Published: September 2023

Abstract: Stunting is a linear growth disorder that is not appropriate for the child's age due to malnutrition. Malnutrition in stunted children can affect bone growth. The process of inhibited bone growth will affect the process of maturation of the periodontal bones that support the teeth being hampered so that children can experience delays in tooth eruption. This study aimed to describe the eruption of the permanent lower central incisors in stunted children at Sekolah Dasar (elementary school) Koto Balingka West Pasaman. This was a quantitative-descriptive-observational study with a case control design. Samples obtained by using purposive sampling technique were 68 children consisting of 34 (50%) stunted children and 34 (50%) normal children aged 6-7 years in the working area of the Parit Koto Balingka Health Center. Univariate analysis was presented in the form of frequency and percentage distributions. The results showed that among stunted children, 22 (64.7%) had not erupted permanent lower central incisors meanwhile 12 (35.3%) children did. Moreover, among normal children, 6 (17.6%) had not erupted permanent lower central incisors meanwhile 28 (82.4%) did. In conclusion, most children aged 6-7 years with stunting have not yet had erupted permanent lower central incisors, meanwhile most children with normal nutritional status have erupted permanent lower central incisors, with a mean age of eruption at 7 years.

Published: September 2023

Abstract
We have deloveloped plastic scintillators loaded with perovskite quantum dots (QDs) to obtain efficient scintillation and enhanced detection efficiency of high-energy photons such as X-rays and gamma rays. In previous studies, the loading of the perovsite QDs was not successful to achieve efficient scintillation owing to the severe self-absorption of the QD emission, which is caused by small Stokes shift of the QDs. In the present study, we added wavelength shifting molecules to suppress the self-absorption. Among three samples, we have succeeded in enhancement in the scintillation light yield and shortening of the scintillation decay by the suppression of the self-absorption in polustyrene-based plastic scintillators added with butyl-PBD, QD-P450, and Coumarin6, and butyl-PBD, QD-P510, and Nile red. This result indicates that it is necessary to avoid the self-absorption to fully exploit the fast and efficient emission of the perovskite QDs.

Published: September 2023

English and Arabic have many similarities and differences with regard to grammar. Consequently, the current paper is designed to investigate the grammatical problems that Iraqi EFL learners suffer from through the process of translation from English to Arabic. It draws upon contrastive analysis (CA) to help in solving the problems which encounter Iraqi EFL morning and evening learners. It aims at examining the contrastive grammatical difficulties and problems that Iraqi EFL learners encounter in English-Arabic translation; presenting a test for identifying the grammatical problems that EFL learners face in English-Arabic translation; providing solutions for such problems. It uses a translation test that consists of 20 items for testing one hundred EFL learners of English department for morning studies and another one hundred for evening studies, college of Education, University of Thi-Qar for the academic year 2022-2023. The test is analysed and discussed. After implementing and discussing the test, the study concluded that hypothesis (1) is verified that the errors students committed are classified as being interlingual or intralingual; hypothesis (2) also verified that here are some aspects in English have no equivalents in Arabic; hypothesis (3) is refuted since tenses and the emphatic do take the highest number of errors that EFL learners (morning and evening participants) commit in English-Arabic translations; hypothesis (4) is partially accepted is partially accepted because of the other simple problems in Arabic-English translation. It is concluded that the majority of Iraqi EFL learners suffer from the tenses, emphatic do, word order, and sentence connectors in English-Arabic translation and both morning and evening students do not suffer from big problems in translating the gerund, Od and Oi, conditional sentences, negation, adjectives, medal auxiliaries, prepositions, and articles in English-Arabic translation

Hypertension is a disease when a person's blood pressure exceeds normal limits. Hypertension can be caused by controllable and uncontrollable factors. Consumption of foods low in fiber, high in fat and sodium is one of the causes factors that can be controlled. This research was to analyze the relationship between intake of fat, fiber, sodium and sleep quality to hypertension in the Central Magelang Health Center area. This case control study used purposive sampling technique with a minimum number of cases and controls for each group of 47 subjects. The inclusion criteria for case subjects were grade 1 and 2 hypertension patients aged 45-59 years and had taken hypertension medication for the last 6 months. The inclusion criteria for the control group were men or women aged 45-59 years who did not had hypertension. Data was obtained by interviews using the SQ-FFQ and PSQI questionnaires. Data was performed using univariate analysis, bivariate analysis with the Spearman test and multivariate analysis with a linear regression test. The results obtained were fat and fiber intake had significant relationship (p-value=0,000) and (p-value=0,014) to systolic blood pressure. Sodium intake and sleep quality had significant relationship ??(p-value=0,000) and (p-value=0,000) to systolic blood pressure and diastolic blood pressure (p-value=0,047) and (p-value=0,003). Fat and fiber intake were related to systolic blood pressure, and sodium intake and sleep quality were related to systolic and diastolic blood pressure in hypertensive patients.

Resumen

El síndrome de Flood es una patología infrecuente, sin prevalencia claramente descrita, que se produce por complicación de una hernia umbilical en pacientes cirróticos con ascitis. Consiste en la ruptura del saco herniario hacia la piel y la salida de líquido ascítico a través del mismo. Habitualmente se relaciona con el grado de hepatopatía, siendo más frecuente en aquellos pacientes con ascitis refractaria y hepatopatía avanzada. Su importancia radica en su elevada mortalidad, cercana al 50%, el riesgo de complicaciones, como la peritonitis bacteriana secundaria, y a la ausencia de un algoritmo de manejo establecido. Presentamos el caso de un paciente cirrótico con ascitis refractaria y hernia umbilical, con salida espontánea de líquido ascítico a través de la misma. Pese a la buena respuesta inicial al tratamiento conservador y a la reducción de la presión intraabdominal, se produjo un deterioro progresivo del estado del paciente, con fallecimiento del mismo, que expone la gravedad de este cuadro.

Abstract
Fast radio bursts (FRBs) are bright radio transients of microsecond to millisecond duration and unknown extragalactic origin. Central to the mystery of FRBs are their extremely high characteristic energies, which surpass the typical energies of other radio transients of similar duration, like Galactic pulsar and magnetar bursts, by orders of magnitude. Calibration of FRB-detecting telescopes for burst flux and fluence determination is crucial for FRB science, as these measurements enable studies of the FRB energy and brightness distribution in comparison to progenitor theories. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a radio interferometer of cylindrical design. This design leads to a high FRB detection rate but also leads to challenges for CHIME/FRB flux calibration. This paper presents a comprehensive review of these challenges, as well as the automated flux calibration software pipeline that was developed to calibrate bursts detected in the first CHIME/FRB catalog, consisting of 536 events detected between 2018 July 25 and 2019 July 1. We emphasize that, due to limitations in the localization of CHIME/FRB bursts, flux and fluence measurements produced by this pipeline are best interpreted as lower limits, with uncertainties on the limiting value.

Abstract
We present an extensive, panchromatic photometric (UV, optical, and near-IR) and low-resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred on the outskirts of the host galaxy NGC 6217. From the V-band light curve, we estimate the plateau length to be ∼ 70 ± 2 days, placing it among the very few well-sampled short plateau supernovae (SNe). With V-band peak absolute magnitude M

V
≤ −17.0 ± 0.1 mag, it falls in the middle of the luminosity distribution of the Type II SNe. The color evolution is typical to other Type II SNe except for an early elbow-like feature in the evolution of V − R color owing to its early transition from the plateau to the nebular phase. Using the expanding photospheric method, we present an independent estimate of the distance to SN 2018gj. We report the spectral evolution to be typical of a Type II SNe. However, we see a persistent blueshift in emission lines until the late nebular phase, not ordinarily observed in Type II SNe. The amount of radioactive nickel (56Ni) yield in the explosion was estimated to be 0.026 ± 0.007 M
⊙. We infer from semianalytical modeling, nebular spectrum, and 1D hydrodynamical modeling that the probable progenitor was a red supergiant with a zero-age-main-sequence mass ≤13 M
⊙. In the simulated hydrodynamical model light curves, reproducing the early optical bolometric light curve required an additional radiation source, which could be the interaction with the proximal circumstellar matter.

Abstract
Coronal Mass Ejections (CMEs) correspond to dramatic expulsions of plasma and magnetic field from the solar corona into the heliosphere. CMEs are scientifically relevant because they are involved in the physical mechanisms characterizing the active Sun. However, more recently, CMEs have attracted attention for their impact on space weather, as they are correlated to geomagnetic storms and may induce the generation of solar energetic particle streams. In this space weather framework, the present paper introduces a physics-driven artificial intelligence (AI) approach to the prediction of CMEs’ travel time, in which the deterministic drag-based model is exploited to improve the training phase of a cascade of two neural networks fed with both remote sensing and in situ data. This study shows that the use of physical information in the AI architecture significantly improves both the accuracy and the robustness of the travel time prediction.

Published: September 2023

Abstract
We have determined absorption oscillator strengths for rotational transitions of the C
2Π(0)-A
2Σ+(0) band of NO, which has been detected in the upper atmosphere of Venus. The molecular quantum defect orbital method has been used in the calculation of the electronic transition moment and the Rydberg–valence interaction between the C
2Π(v = 0) and the B
2Π (v = 7) states has been considered. Considerable deviations from normal intensity distribution of the rotational lines have been found at J ≤ 5.5. As far as we know, the present line f-values are reported here for the first time. These data may be useful in the interpretation of the observations obtained by the Visible and Infrared Thermal Imaging Spectrometer instrument on the Venus Express spacecraft.
Investigation of Superhumps in SU UMa-type Dwarf Novae Based on the Observations of TESS
Authors: Liu Wei , Qian Shengbang 
Published: September 2023

Abstract
We report a superhumps analysis of seven SU UMa-type dwarf novae based on observations made by the Transiting Exoplanet Survey Satellite (TESS). Superhumps are seen during the superoutbursts of SU UMa-type dwarf novae. The monthlong data sets of TESS are well suited for studying the variations of superhumps. We selected seven non-eclipsing SU UMa-type dwarf novae with superhumps in which TESS light curves are available and have not yet been studied. The A, B, and C stages of superhumps in superoutbursts were determined by the O − C method. The results indicate that not all complete superoutbursts show three obvious stages, such as DT Oct and the second superoutburst of J1730+6247. We calculated the superhump period for each stage and the mean period for all superoutbursts. Taking the stage A superhump method, the mass ratio (M2/M1) was estimated. According to the results, the seven stars are pre-bounce systems with mass ratios ranging from 0.1 to 0.2. By combining the orbital periods and the mean superhump periods, the precession periods were calculated. The results show that the precession periods of the seven SU UMa stars are about 2 days.
Wobbling Jets in Common Envelope Evolution
Authors: Dori Noam , Bear Ealeal , Soker Noam 
Published: September 2023

Abstract
We find that the convective motion in the envelopes of red supergiant (RSG) stars supplies a non-negligible stochastic angular momentum to the mass that a secondary star accretes in a common envelope evolution (CEE), such that jets that the secondary star launches wobble. The orbital motion of the secondary star in a CEE and the density gradient in the envelope impose a nonzero angular momentum to the accreted mass with a constant direction parallel to the orbital angular momentum. From one-dimensional stellar evolution simulations with the numerical code mesa we find that the stochastic convection motion in the envelope of RSG stars adds a stochastic angular momentum component with an amplitude that is about 0.1–1 times that of the constant component due to the orbital motion. We mimic a CEE of the RSG star by removing envelope mass at a high rate and by depositing energy into its envelope. The stochastic angular momentum implies that the accretion disk around the secondary star (which we do not simulate), and therefore the jets that it launches, wobble with angles of up to tens of degrees with respect to the orbital angular momentum axis. This wobbling makes it harder for jets to break out from the envelope and can shape small bubbles in the ejecta that compress filaments that appear as arcs in the ejected nebula, i.e., in planetary nebulae when the giant is an asymptotic giant branch star.
Long-term X-Ray Outburst in the TeV-detected Blazar Mrk 501 in 2021–2022: Further Clues for the Emission and Unstable Processes
Authors: Kapanadze B. , Gurchumelia A. , Aller M. 
Published: September 2023

Abstract
This paper presents the results of a detailed X-ray timing and spectral analysis of Mrk 501, which are based mainly on the Swift data obtained during 2021 February–2022 December. The source showed strongly enhanced X-ray activity, characterized by a long-term increase in the baseline 0.3–10 keV flux level superimposed by shorter-term flares on timescales of a few weeks to about 2 months. During some time intervals, Mrk 501 was the brightest blazar in the X-ray sky and, moreover, showed an intense intraday variability, which was sometimes detected within the exposures lasting a few hundred seconds. These instances were characterized by fractional variability amplitudes of 4%–18% and were mostly observed during short-term X-ray flares. The source exhibited extreme spectral properties with dominance of the spectral curvature, frequent occurrence of hard photon indices in the 0.3–10 keV and 0.3–300 GeV bands, and the peak of a synchrotron spectral energy distribution in the hard X-ray range. These properties demonstrate the importance of relativistic magnetic reconnection, first-order Fermi mechanism within the magnetic field of different confinement efficiencies, stochastic acceleration, and hadronic processes. The X-ray and γ-ray fluxes showed a log-normal distribution, which hints at the imprint of accretion disk instabilities on the blazar jet, as well as the possible presence of hadronic cascades and random fluctuations in the particle acceleration rate. The optical–UV and γ-ray variabilities showed a weak or absent correlation with the X-ray flaring activity, which is not consistent with simple leptonic models and requires more complex particle acceleration, emission, and variability scenarios.
