Pijat bayi merupakan terapi sentuh kontak langsung dengan tubuh yang dapat memberikan rasa aman dan nyaman pada bayi. Sentuhan dan pelukan dari seorang ibu adalah kebutuhan dasar bayi. Jika pijat bayi dilakukan secara teratur akan meningkatkan hormon katekolamin (epinefrin dan norepinefrin) yang dapat memicu stimulasi tumbuh kembang karena dapat meningkatkan nafsu makan, meningkatkan berat badan, dan merangsang perkembangan struktur maupun fungsi otak (Riksani, 2012). Namun teknik pijat bayi yang tepat belum banyak diketahui oleh masyarakat. Survey pendahuluan di Klinik Citra Marendal diperoleh hampir semua orang tua beranggapan bahwa pijat bayi tidak dapat dilakukan di rumah secara mandiri dan hanya di lakukan dukun beranak.

Charged Particle Circular Orbits around Weakly Charged and Magnetized Kerr Black Holes
Authors: Al Zahrani A. M. 
Published: September 2022

Abstract
We study the circular orbits of charged particles around a weakly charged Kerr black hole immersed in a weak, axisymmetric magnetic field. First, we review the circular orbits of neutral particles. We then review the circular orbits of charged particles around a weakly charged Kerr black hole and weakly magnetized Kerr black hole. The case of a weakly magnetized and charged black hole is investigated thereafter. We investigate, in particular, the effect of the electromagnetic forces on the charged particles’ innermost stable circular orbits. We examine the conditions for the existence of negative-energy stable circular orbits and the possibility of the emergence of a gap or double orbit in thin accretion disks. Some of the interesting astrophysical consequences of our findings are discussed as well.
Comparing the Counter-beaming and Temperature Anisotropy Driven Aperiodic Electron Firehose Instabilities in Collisionless Plasma Environments

Published: September 2022

Abstract
The electron firehose instabilities are among the most studied kinetic instabilities, especially in the context of space plasmas, whose dynamics is mainly controlled by collisionless wave–particle interactions. This paper undertakes a comparative analysis of the aperiodic electron firehose instabilities excited either by the anisotropic temperature or by the electron counter-beaming populations. Two symmetric counter-beams provide an effective kinetic anisotropy similar to the temperature anisotropy of a single (nondrifting) population, with the temperature along the magnetic field direction larger than that in the perpendicular direction. Therefore, the counter-beaming plasma is susceptible to firehose-like instabilities (FIs), parallel and oblique branches. Here we focus on the oblique beaming FI, which is also aperiodic when the free energy is provided by symmetric counter-beams. Our results show that, for relative small drifts or beaming speeds (U), not exceeding the thermal speed (α), the aperiodic FIs exist in the same interval of wavenumbers and the same range of oblique angles (with respect to the magnetic field direction), but the growth rates of counter-beaming FI (CBFI) are always higher than those of temperature anisotropy FI (TAFI). For U/α > 1, however, another electrostatic two-stream instability is also predicted, which may have growth rates higher than those of CBFI, and may dominate in that case the dynamics.
A Dynamic Deep-learning Model for Generating a Magnetogram Sequence from an SDO/AIA EUV Image Sequence

Published: September 2022

Abstract
The solar magnetic field dominates solar activities in the solar atmosphere, such as solar flares and coronal mass ejections (CMEs). The Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) has been in operation from 2010, providing a full-disk photospheric magnetogram. However, with a single view of observation, SDO/HMI cannot provide a global view of the Sun at the same time, so the farside of the Sun is blind to us. The Solar Terrestrial Relations Observatory (STEREO) provides two different views of the Sun with complementary viewing angles relative to SDO/HMI. However, it did not carry a magnetograph, but an extreme-ultraviolet (EUV) imager. Fortunately, deep learning has been proved to generate a solar farside magnetogram from STEREO farside EUV observation. Although a single generated magnetogram is morphologically very similar to ground truth, the sequence of the generated magnetogram has noticeable magnetic field fluctuation, which cannot be ignored when it is displayed as a time series, especially at an active region. This fluctuation is represented by sudden magnetic polarity reversal and drifting of magnetic field distribution. To mitigate this problem, a novel dynamic deep-learning model by integrating a convolutional gated recurrent units (convGRU) model into a pix2pix baseline is proposed in this paper. It can generate a sequence of a magnetogram with smooth transition among consecutive magnetograms by exploring spatio-temporal information of an input EUV image sequence. From both quantitative and qualitative comparisons, the proposed model can generate a magnetogram sequence more close to real observation.
A Catalog of Faculae, Prominences, and Filaments for the Period 1929–1944 from the Astronomical Observatory of the University of Coimbra
Authors: Carrasco V. M. S. , Vaquero J. M. 
Published: September 2022

Abstract
The Astronomical Observatory of the University of Coimbra (Portugal) published a catalog with solar observations such as sunspots, faculae, prominences, and filaments for the period 1929–1944. In previous works, a machine-readable version on sunspot observations made in Coimbra was published. Here we extend that work and present a digital version of the facula, prominence, and filament observations made in that observatory. We have applied a quality control to the catalog, obtaining that the percentage of problematic or suspicious data found is lower than 1% of the total number of observations. In addition, we show an analysis of this catalog, as well as some comparisons between solar indices calculated from Coimbra data and those from other sources. Historical observations of faculae, prominences, and filaments are not as common as sunspot records, and in addition, few historical series of these solar features are available in digital version. For that reason, the catalog of solar observations published by the Coimbra Observatory is of enormous value. The recovery, publication, and availability of this catalog provide the scientific community with a valuable data set of solar characteristics that will help us to study in more detail the past solar magnetic field and long-term solar activity.

Abstract
Based on the database monitored by the 1.26 m National Astronomical Observatory–Guangzhou University Infrared/Optical Telescope, we studied the optical variabilities of FSRQ 3C454.3. The monitoring period was from 2016 October 17 to 2018 December 14, and there were 6701 observations covering the g, r, and i bands (2196 at the g band, 2214 at the r band, and 2291 at the i band). (1) The maximum variabilities were Δm

g
= 2.806 ± 0.124 mag at the g band; Δm

r
= 2.365 ± 0.160 mag at the r band; and Δm

i
= 3.126 ± 0.070 mag at the i band. (2) Among the gri intraday lightcurves, there are 172 portions of the data sets showing intraday variability (IDV). The distributions of IDV timescales (ΔT) can be profiled by a three-order Gaussian function, with the center values ΔT
1 = 17.18 minutes, ΔT
2 = 34.91 minutes, and ΔT
3 = 68.92 minutes. These results imply that the origin of IDVs is very complicated. (3) Based on the IDV timescales, we obtained the emission size R ≤ 7.17 × 1015 cm, fixed the broad-line region and modeled the spectral energy distributions. (4) We used the Jurkevich method, red-noise fitting, and the weighted wavelet Z-transform to analyze the long-term variabilities and obtained indications of a possible period of P = 2.92 ± 0.85 yr, and used the binary black hole system to explain this period. Based on the long-term period, we can estimate the time until merger of the binary black hole, t
merge = 6.69 × 103 yr, and the luminosity of gravitational waves, L

G
= 1.56 × 1048 erg s−1.
The Yarkovsky Effect in REBOUNDx

Published: September 2022

Abstract
To more thoroughly study the effects of radiative forces on the orbits of small, astronomical bodies, we introduce the Yarkovsky effect into reboundx, an extensional library for the N-body integrator rebound. Two different versions of the Yarkovsky effect (the “Full Version” and the “Simple Version”) are available for use, depending on the needs of the user. We provide demonstrations for both versions of the effect and compare their computational efficiency with another previously implemented radiative force. In addition, we show how this effect can be used in tandem with other features in reboundx by simulating the orbits of asteroids during the asymptotic giant branch phase of a 2 M
☉ star. This effect is made freely available for use with the latest release of reboundx.
Analysis and Modeling of High-frequency Emission and Deep Seismic Sources of Sunquakes
Authors: Stefan John T. , Kosovichev Alexander G. 
Published: September 2022

Abstract
Recent work published by Lindsey et al. find evidence for a deep and compact seismic source for the sunquake associated with the 2011 July 30 M9.3 flare, as well as seismic emission extending up to 10 mHz. We examine the sunquake independently, and a possible wave front is found in the 8 mHz band, though no wave front is easily discernible in the 10 mHz band. Additionally, we perform numerical simulations of seismic excitation modeled with the reported parameters and changes in the power spectra with increasing depth of the excitation source are examined. It is found that the peak frequency decreases for increasing depths, but a shallow minimum is indicated between z = 0 and z = −840 km. Analysis of the suspected wave front of the M9.3 sunquake finds that the power spectrum of the reported seismic emission is close to that of background oscillations, though with a peak frequency noticeably lower than the background peak. Additionally, it is found that the amplitude of the source estimated by Lindsey et al. is too low to produce the observed wave front.
Dynamical Unification of Tidal Disruption Events
Authors: Thomsen Lars L. , Kwan Tom M. , Dai Lixin , Wu Samantha C. , Roth Nathaniel , Ramirez-Ruiz Enrico 
Published: September 2022

Abstract
The ∼100 tidal disruption events (TDEs) observed so far exhibit a wide range of emission properties both at peak and over their lifetimes. Some TDEs radiate predominantly at X-ray energies, while others radiate chiefly at UV and optical wavelengths. While the peak luminosities across TDEs show distinct properties, the evolutionary behavior can also vary between TDEs with similar peak emission properties. In particular, for optical TDEs, while their UV and optical emissions decline somewhat following the fallback pattern, some events can greatly rebrighten in X-rays at late time. In this Letter, we conduct three-dimensional general relativistic radiation magnetohydrodynamics simulations of TDE accretion disks at varying accretion rates in the regime of super-Eddington accretion. We make use of Monte Carlo radiative transfer simulations to calculate the reprocessed spectra at various inclinations and at different evolutionary stages. We confirm the unified model proposed by Dai et al., which predicts that the observed emission largely depends on the viewing angle of the observer with respect to the disk orientation. Furthermore, we find that disks with higher accretion rates have elevated wind and disk densities, which increases the reprocessing of the high-energy radiation and thus generally augments the optical-to-X-ray flux ratio along a particular viewing angle. This implies that at later times, as the accretion level declines, we expect that more X-rays will leak out along intermediate viewing angles. Such dynamical model for TDEs can provide a natural explanation for the diversity in the emission properties observed in TDEs at peak and along their temporal evolution.

The article presents the results of work aimed at solving the problem of measuring the coolant level in miscellaneous tanks of liquid-metal-cooled reactor plants, mainly of an integral layout with a free level of the primary coolant. The choice of relevant measuring means and methods is limited by the extreme parameters of the liquid metal coolant (LMC) and operating conditions. Traditional measuring means are practically unsuitable; therefore, measuring the HLMC level is a complex technical task. Based on this review, they propose and describe a method of pulsed microwave reflectometry as the most promising in terms of combining the characteristics of reliability, accuracy and ease of use. The results of the experimental study demonstrated the efficiency of the level gauge, which worked according to this method, for measuring the level of lead-bismuth coolant in the control tank under conditions close to natural ones. An analysis of the results confirmed the possibility of using this method to control the level of melts of various metals as applied to HLMC reactor plants.
Using the device for measuring the level, which works according to the proposed method, it is possible to control the level of melt of various metals in tanks in real time without the need to move various parts of the sensitive element of the level gauge while maintaining the tightness of the circuit. This device is applicable for various nuclear power plants, accelerator-controlled systems, research reactors and experimental facilities with liquid metal coolants.
News literacy and online news between Egyptian and Spanish youth: Fake news, hate speech and trust in the media
Authors: Samy-Tayie Sally , Tejedor Santiago , Pulido Cristina 
Published: September 2022

Exposure to harmful content, fake news, and hate speech, calls to question whether citizens are 'responsible' when it comes to their online news behavior. This exploratory study aims to positioning news literacy as a mediating factor toward fostering civic responsibility by investigating its role in enhancing youth's online news experience and preparing them against harmful content. News literacy is defined as a multi-structural construct with three main constituents: motivation, knowledge, and skills. The study's main goal is accomplished through delving into youth's online news experience, and assessing their level of news literacy through a mixed methods approach relying on focus group discussions as a qualitative method and survey as a quantitative method. The study is applied to a sample of youth from Egypt and a sample of youth from Spain, on whom comparative analysis is conducted. Findings reveal a positive correlation between news literacy and: the ability to identify fake news, the ability to identify hate speech, engagement with news, caring about the veracity of content before sharing, and motivation to seek news. Negative perceptions about professional news media's performance have been expressed by respondents from both countries, with the main justification being that news media are not fulfilling their role as should be.
La exposición a contenidos nocivos, noticias falsas y discursos de odio hace que nos preguntemos si los ciudadanos son «responsables» cuando hablamos de su comportamiento online. Este estudio exploratorio pretende posicionar la alfabetización periodística como un factor mediador hacia el fomento de la responsabilidad cívica, investigando su papel en la mejora de la experiencia de los jóvenes con las noticias online, preparándolos contra los contenidos nocivos. La alfabetización periodística se define como un concepto multiestructural con tres componentes principales: motivación, conocimientos y habilidades. Un objetivo del estudio es profundizar en la experiencia de los jóvenes con las noticias online, evaluando su nivel de alfabetización periodística mediante un enfoque de métodos mixtos que se basan en discusiones de grupos focales y en una encuesta. El estudio se aplica a una muestra de jóvenes de Egipto y a otra de jóvenes de España, a partir de las cuales se realiza un análisis comparativo. Los resultados revelan una correlación positiva entre la alfabetización periodística y: la capacidad de identificar las noticias falsas y el discurso de odio, el compromiso con las noticias, la preocupación por la veracidad del contenido antes de compartirlo y la motivación para buscar noticias. Los encuestados de ambos países han expresado percepciones negativas sobre la eficacia de los medios de comunicación profesionales, con la justificación principal de que los medios de comunicación no están cumpliendo su función como deberían.
La victime « à la française » et le parquet
Authors: Albernaz Frederico 
Published: September 2022

« La partie civile et le parquet sont deux traits distinctifs du système juridique français qui sont connus dans le monde entier. D'un côté le modèle unique d'une victime qui peut se constituer partie civile et déclencher la poursuite. De l'autre, le ministère public, institution typiquement française, hiérarchisé et dépendant du pouvoir exécutif, dont les attributions sont constamment renforcées. Mais quelle est la relation entre eux ? Quels peuvent être leurs rapports ? Leurs rôles sont-ils conciliables ? On observe sur la scène mondiale que ces deux acteurs de la procédure pénale sont de moins en moins éloignés et que la concurrence entre le rôle du parquet et celui de la victime ne doit pas signifier un antagonisme. »

Évolution du rapport à la mort : déni et risques psychopathologiques
Authors: Cognet Anna , Mégalakaki-Manoussakis Olga 
Published: September 2022

L’étude de l’évolution anthropologique en France du rapport à la mort nous permet de mettre en lumière des formes de déni face à la finitude. En effet, au cours des siècles, nous observons un processus d’abstraction des pratiques religieuses et des rites sociaux en règle générale, dont les rituels funéraires. Les pratiques funéraires tendent vers davantage d’épuration symbolique, ce qui s’origine dans une modification de notre rapport à la mort. Notre regard sur la mort semble avoir évolué vers davantage de déni, entraînant un rejet également des pratiques funéraires associées, en tant que celles-ci accordent une telle valeur à la mort, qu’elles la rendent impossible à ignorer. C’est sur les conséquences psychiques, éventuelles ou avérées, de cette évolution de notre société vis-à-vis de la mort, que nous allons nous pencher en tant que psychologues, afin de déterminer l’impact de la disparition des pratiques funéraires sur l’élaboration du processus de deuil. Dans un premier temps, nous décrirons ce processus d’abstraction des rituels en le contextualisant dans l’évolution anthropologique du rapport à la mort depuis le Moyen Âge jusqu’à nos jour. Nous évoquerons ensuite les risques psychiques associés à la « société post-mortelle » et leurs conséquences tangibles sur rituels funéraires par le prisme de quatre rituels classiques : le deuil en noir, la toilette mortuaire, les sépultures multiples et le dépôt d’objets. Enfin, nous aborderons les nouveaux rituels, créatifs et personnels, qui émergent de l’absence sociétale de rites contenants.
Un tremplin pour sauter dans la jouissance
Authors: Fierens Christian 
Published: September 2022

Au lieu d’essayer de différencier des genres (hommes, femmes, lesbiennes, homosexuels, bisexuels, transgenres, etc.), l’approche de la sexualité doit être focalisée sur l’expérience singulière (« pas tout ») qu’il est impossible de réduire à aucune espèce d’universalité. Les formules lacaniennes de la sexuation comme telles ne sont pas les formules de la masculinité et de la féminité, mais le chemin pour le mouvement de tout être humain vers la jouissance et le principe propre de l’inconscient. (En lisant la leçon du 13/3/1973 – Séminaire xx Encore ).

Le propos est de dégager la signification d’une instance inconsciente du « premier venu » dans le devenir-femme. Moment de dissémination du désir d’une femme, en un tournant de son existence. Après une phénoménologie de cet épisode, de ses conjonctures et de ses manifestations et son écho dans l’œuvre littéraire, on accoste sur une logique de ce choix d’objet, en s’appuyant sur une formule gnomique ovidienne suggérant l’enjeu du lien incestueux en acte de la fille au père. Ce qui permet de dégager les avatars du lien à l’Un. « Posthistoire » de l’œdipe et du recours au « semblant masculin ».
