Senior High School (SMA) is a secondary education level in formal education in which there are majors so that students are more focused on one form of learning group according to their interests and potential. SMA Negeri 1 Cawas often experiences time constraints in carrying out the student majoring process, this is caused by a lack of facilities that can help schools to simplify and speed up the student majoring process so that reports that should have been made are still being processed.
The decision support system was created to facilitate the determination of major classes and speed up the process of dividing majors. Data processing in this study uses the MOORA method. This system processes student data, criteria data, value data, and department data. With this system, it can be used as an alternative to help schools to make it easier in the process of determining and classifying major classes and speeding up the process of dividing student majors.

Published: April 2024

Cassava brown streak disease (CBSD) is a devastating disease of cassava in Uganda. Limited information exists on the incidence and severity of CBSD in Northern Uganda. The prevalence of CBSD in the eight (8) districts in the Acholi sub-region is also unknown. Therefore, the current study intended to: a) determine the prevalence and severity of CBSD in the Acholi sub-region, and b) identify the drivers of CBSD epidemics in smallholder cassava cropping systems in Acholi. An assessment of 120 cassava fields was conducted in the 2018b season. CBSD field incidence was highest in Nwoya District (51.3%) and lowest in Kitgum (6.4%), with severity ranging from 2.1 to 3.4 in the sub-region. CBSD prevalence was also highest in Nwoya (76.2%) and lowest in Kitgum and Pader Districts (30.8%). The use of CBSD-susceptible varieties (TME 14, TME 204, and NASE 12) was identified as the main driver of the epidemic. The result of the current study highlights the need for a wide-scale CBSD awareness creation and community-based cassava seed multiplication and distribution system in the Acholi sub-region to promote the up-take of CBSD-tolerant cassava varieties

Published: April 2024

Background: Stethoscopes and mannequins are basic tools for medical practitioners to diagnose various problems. Restricted by space, resources, and time, these tools and common video training are sometimes inaccessible. These obstacles may be solved by immersive virtual reality (VR) that improves interaction and blurs the line between virtual and reality. Therefore, this study combines virtual and real interaction technologies to investigate the impact of multi-sensory interaction on learning outcomes in chest auscultation.Methods: This study integrated VIVE Tracker technology to provide synchronized tactile stimulation in VR. University students in medical-related disciplines participated in the study. Interviews were conducted to understand how students perceived the effectiveness and usefulness of the thoracic auscultation VR.Conclusion: Most students expressed that tactile stimulation gave realistic sensations and effectively reinforced the immersive effect. Simultaneously, it increased their interest and motivation in learning. The integration of synchronized tactile stimulation is a novel approach that expands the realm of interactivity beyond handheld controller manipulation and creates a platform to simulate medical-related scenarios to learn complex knowledgeand skills.

Published: April 2024

Background: In emergency care, the most important thing to note is the speed of nurses in responding or acting on the first patient who enters the emergency room. This speed is often referred to as response time. Nurse response time is always a measure of the service quality of a hospital or health center. Response times depend on the speed available as well as the quality of assistance to save lives and prevent infirmity. Objectives: Patients visiting to the hospital should be treated promptly and that leads to improvement in the quality of services and patient safety. The study aimed to determine the factors related to the response time of nurses in management of upper GI bleeding among chronic liver disease patients at Institute of Liver and Biliary Sciences, New Delhi, India.Methods: Carrying out the research is from February to March 2022. Analytical survey design with a cross- sectional approach. The research subjects were 20 nurses. measuring tools, namely questionnaires. analysis used bivariate analysis used the Chi-Square Test.Results: This shows that there is a relationship between education and response time with a value of p-value =.008, knowledge and response time with a value of p-value = .003.Conclusion: The level of knowledge and clinical experience determines Nurses to make prompt decision and ability to provide assessment and nursing actions. As the Nurses getting higher education levels and experience also increasing, on average they remain engaged in their work for longer time, so they are more productive and nurses have attended more training to improve their skills.
Top-down suppression of negative features applies flexibly contingent on visual search goals
Authors: Forstinger Marlene , Ansorge Ulrich 
Published: April 2024

AbstractVisually searching for a frequently changing target is assumed to be guided by flexible working memory representations of specific features necessary to discriminate targets from distractors. Here, we tested if these representations allow selective suppression or always facilitate perception based on search goals. Participants searched for a target (i.e., a horizontal bar) defined by one of two different negative features (e.g., not red vs. not blue; Experiment 1) or a positive (e.g., blue) versus a negative feature (Experiments 2 and 3). A prompt informed participants about the target identity, and search tasks alternated or repeated randomly. We used different peripheral singleton cues presented at the same (valid condition) or a different (invalid condition) position as the target to examine if negative features were suppressed depending on current instructions. In all experiments, cues with negative features elicited slower search times in valid than invalid trials, indicating suppression. Additionally, suppression of negative color cues tended to be selective when participants searched for the target by different negative features but generalized to negative and non-matching cue colors when switching between positive and negative search criteria was required. Nevertheless, when the same color – red – was used in positive and negative search tasks, red cues captured attention or were suppressed depending on whether red was positive or negative (Experiment 3). Our results suggest that working memory representations flexibly trigger suppression or attentional capture contingent on a task-relevant feature’s functional meaning during visual search, but top-down suppression operates at different levels of specificity depending on current task demands.

Abstract
We study the physical properties and 3D distribution of molecular clouds (MCs) toward the Cygnus region using the MWISP CO survey and Gaia DR3 data. Based on Gaussian decomposition and clustering for 13CO lines, over 70% of the fluxes are recovered. With the identification result of 13CO structures, two models are designed to measure the distances of the molecular gas in velocity crowding regions. The distances of more than 200 large 13CO structures are obtained toward the 150 deg2 region. Additionally, tens of the identified MC structures coincide well with masers and/or intense mid-IR emission. We find multiple gas layers toward the region: (1) the extensive gas structures composing the Cygnus Rift from 700 pc to 1 kpc across the whole region; (2) the ∼1.3 kpc gas layer mainly in the Cygnus X South region; and (3) the 1.5 kpc dense filament at the Cygnus X North region and many cometary clouds shaped by Cygnus OB2. We also note that the spatial distribution of young stellar object candidates is generally consistent with the molecular gas structures. The total molecular mass of the Cygnus region is estimated to be ∼2.7 × 106

Low-mass Population III Star Formation due to the HD Cooling Induced by Weak Lyman–Werner Radiation
Authors: Nishijima Sho , Hirano Shingo , Umeda Hideyuki 
Published: April 2024

Abstract
Lyman–Werner (LW) radiation photodissociating molecular hydrogen (H2) influences the thermal and dynamical evolution of the Population III (Pop III) star-forming gas cloud. The effect of powerful LW radiation has been well investigated in the context of supermassive black hole formation in the early Universe. However, the average intensity in the early Universe is several orders of magnitude lower. For a comprehensive study, we investigate the effects of LW radiation at 18 different intensities, ranging from J
LW/J
21 = 0 (no radiation) to 30 (H-cooling cloud), on the primordial star-forming gas cloud obtained from a three-dimensional cosmological simulation. The overall trend with increasing radiation intensity is a gradual increase in the gas cloud temperature, consistent with previous works. Due to the HD cooling, however, the dependence of gas cloud temperature on J
LW deviates from the aforementioned increasing trend for a specific range of intensities (J
LW/J
21 = 0.025–0.09). In HD-cooling clouds, the temperature remained below 200 K during 105 yr after the first formation of the high-density region, maintaining a low accretion rate. Finally, the HD-cooling clouds have only a low-mass dense core (above 108 cm−3) with about 1–16 M

Published: April 2024

Abstract
Primordial black holes (PBHs) could explain some fraction of dark matter and shed light on many areas of early-Universe physics. Despite over half a century of research interest, a PBH population has so far eluded detection. The most competitive constraints on the fraction of dark matter comprised of PBHs (f
DM) in the (10−9–10)M
⊙ mass ranges come from photometric microlensing and bound f
DM ≲ 10−2–10−1. With the advent of the Roman Space Telescope with its submilliarcsecond astrometric capabilities and its planned Galactic Bulge Time Domain Survey (GBTDS), detecting astrometric microlensing signatures will become routine. Compared with photometric microlensing, astrometric microlensing signals are sensitive to different lens masses–distance configurations and contain different information, making it a complimentary lensing probe. At submilliarcsecond astrometric precision, astrometric microlensing signals are typically detectable at larger lens–source separations than photometric signals, suggesting a microlensing detection channel of pure astrometric events. We use a Galactic simulation to predict the number of detectable microlensing events during the GBTDS via this pure astrometric microlensing channel. Assuming an absolute astrometric precision floor for bright stars of 0.1 mas for the GBTDS, we find that the number of detectable events peaks at ≈103

Solar Chromospheric Heating by Magnetohydrodynamic Waves: Dependence on the Inclination of the Magnetic Field
Authors: Koyama Mayu , Shimizu Toshifumi 
Published: April 2024

Abstract
A proposed mechanism for solar chromospheric heating is magnetohydrodynamic waves propagating upward along magnetic field lines and dissipating their energy in the chromosphere. In particular, compressible magnetoacoustic waves may contribute to the heating. Theoretically, the components below the cutoff frequency cannot propagate into the chromosphere; however, the cutoff frequency depends on the inclination of the magnetic field lines. In this study, using high-temporal cadence spectral data of IRIS and Hinode Solar Optical Telescope spectropolarimeter in plages, we investigated the dependence of the low-frequency waves on magnetic field properties and quantitatively estimated the amount of energy dissipation in the chromosphere. The following results were obtained: (a) The amount of energy dissipated by the low-frequency component (3–6 mHz) increases with the inclination of the field below 40°, whereas it decreases as a function of the inclination of the field above 40°. (b) The amount of the energy is enhanced toward 104 W m−2, which is the energy required for heating in the chromospheric plage regions when the magnetic field is higher than 600 G and inclined more than 40°. (c) In the photosphere, the low-frequency component has much more power in the magnetic field inclined more and weaker than 400 G. The results suggest that the observed low-frequency components can bring the energy along the magnetic field lines and that only a specific range of the inclination angles of the field and the strength of the field may allow the low-frequency component to bring a sufficient amount of the energy into the chromosphere.

Abstract
Identifying and classifying variable stars is essential to time-domain astronomy. The Large Area Multi-Object Fiber Optic Spectroscopic Telescope (LAMOST) acquired a large amount of spectral data. However, there is no corresponding variable source-related information in the data, constraining LAMOST data utilization for scientific research. In this study, we systematically investigated variable source classification methods for LAMOST data. We constructed a 10-class classification model using three mainstream machine-learning methods. Through performance comparison, we chose the LightGBM and XGBoost models. We further identified variable source candidates in the r band in LAMOST DR9 and obtained 281,514 variable source candidates with probabilities greater than 95%. Subsequently, we filtered out the sources of periodic variable sources using the generalized Lomb–Scargle periodogram and classified these periodic variable sources using the classification model. Finally, we propose a reliable periodic variable star catalog containing 176,337 stars with specific types.

Abstract
We present the first detection in space of thionylimide (HNSO) toward the Galactic center molecular cloud G + 0.693-0.027, thanks to the superb sensitivity of an ultradeep molecular line survey carried out with the Yebes 40 m and IRAM 30 m telescopes. This molecule is the first species detected in the interstellar medium containing, simultaneously, N, S, and O. We have identified numerous K

a
= 0, 1, and 2 transitions belonging to HNSO covering from J
up = 2 to J
up =10, including several completely unblended features. We derive a molecular column density of N = (8 ± 1)×1013 cm−2, yielding a fractional abundance relative to H2 of ∼6 × 10−10, which is about ∼37 and ∼4.8 times less abundant than SO and SO2, respectively. Although there are still many unknowns in the interstellar chemistry of NSO-bearing molecules, we propose that HNSO is likely formed through the reaction of the NSO radical and atomic H on the surface of icy grains, with alternative routes also deserving exploration. Finally, HNSO appears as a promising link between N, S, and O interstellar chemistry, and its discovery paves the route to the detection of a new family of molecules in space.
Tidal Disruption Encores

Published: April 2024

Abstract
Nuclear star clusters (NSCs), made up of a dense concentration of stars and the compact objects they leave behind, are ubiquitous in the central regions of galaxies surrounding the central supermassive black hole (SMBH). Close interactions between stars and stellar-mass black holes (sBHs) lead to tidal disruption events (TDEs). We uncover an interesting new phenomenon: for a subset of these, the unbound debris (to the sBH) remains bound to the SMBH, accreting at a later time, thus giving rise to a second flare. We compute the rate of such events and find them ranging within 10−6–10−3 yr−1 gal−1 for SMBH mass ≃106–109
M
⊙. Time delays between the two flares spread over a wide range, from less than a year to hundreds of years. The temporal evolution of the light curves of the second flare can vary between the standard t
−5/3 power law to much steeper decays, providing a natural explanation for observed light curves in tension with the classical TDE model. Our predictions have implications for learning about NSC properties and calibrating its sBH population. Some double flares may be electromagnetic counterparts to LISA extreme-mass-ratio inspiral sources. Another important implication is the possible existence of TDE-like events in very massive SMBHs, where TDEs are not expected. Such flares can affect spin measurements relying on TDEs in the upper SMBH range.
Amitié et amour : passages
Authors: Golse Bernard 
Published: April 2024

Les enfants font très tôt la différence entre l’amour et l’amitié comme s’ils disposaient de proto-représentations quasi d’emblée différenciées de ces deux états psychiques fondamentaux. Mais peut-être pressentent-ils aussi très vite la place particulière qu’occupe l’amour dans l’esprit des adultes qui prennent soin d’eux avec sa charge de mystères et d’interdits… Penser la différence entre l’amour et l’amitié sous le seul angle des processus de sublimation et de désublimation a quelque chose d’insuffisant. L’auteur tente de montrer que l’amour et l’amitié n’impliquent sans doute pas les mêmes niveaux de la représentation d’objet, mais aussi que la problématique de « l’Amour fou » peut, quant à elle, tout à fait concerner les bébés et qu’enfin les questions de l’amour et de l’amitié ne sont pas entièrement clivables compte tenu de la dose de passion qui peut plus ou moins souvent infiltrer l’amitié aussi bien quand elle précède l’amour que quand elle lui succède.
