Understanding Mental Burnout in Hospital Raja Permaisuri Bainun: Prevalence and Coping Mechanisms among Healthcare Professionals
Authors: Rezuan Nuratikah Adillah , Abdul Jalil Aina Amanina , Mohd Noordin Zakiah 
Published: February 2025

Burnout is a significant and growing concern among healthcare professionals at Hospital Raja Permaisuri Bainun (HRPB), with doctors, nurses, and pharmacists particularly affected by high-stress demands. Burnout not only impacts the mental health and well-being of these professionals but also affects the quality of patient care, leading to issues such as medical errors, reduced productivity, and high staff turnover. Addressing burnout requires a comprehensive understanding of the factors contributing to it, as well as the coping mechanisms used by healthcare workers to manage this condition. Without this knowledge, it is challenging to design effective interventions that support mental health in high-pressure healthcare environments. The aim of this study is to examine the prevalence, associated factors and coping strategies related to burnout among healthcare professionals at HRPB. Methods: An analytic observational method with a cross-sectional design was employed, gathering data through online and printed questionnaires. Participants were recruited using non-probability convenience and snowball sampling methods. Descriptive statistics were used to analyse the prevalence and coping mechanisms of burnout, while Pearson’s Chi-Square and inferential statistics identified associations between burnout and demographic factors such as age, gender, and educational background, with a significance level set at p-value < 0.05. The study found a moderate prevalence of burnout (54.7%) among healthcare professionals at HRPB, with personal and work factors (81.9%) and patient-related factors (85.5%) as the most frequent contributors. Among coping mechanisms, religion was the most frequently utilised strategy, suggesting its prominent role in resilience building. Burnout is moderately prevalent among healthcare professionals at HRPB and is significantly influenced by socio-demographic factors, such as age and professional status. Religion plays a primary role as a coping mechanism, pointing to the importance of spiritual support in mitigating burnout. These findings highlight the need for targeted interventions and training programmes within government institutions to support mental health, improve job satisfaction, and reduce burnout among healthcare professionals.

Abstract
We reanalyze VLT/SPHERE-IRDIS K- and H-band sparse aperture masking interferometry data of the transition disk HD 100546 observed in 2018 and 2021, respectively. We fit geometrical models to the closure phases extracted from both datasets. We compare three model classes: a forward scattering disk, a forward scattering disk plus an arbitrary asymmetric disk feature, and a forward scattering disk plus an unresolved point source in the disk gap. We find that the forward scattering disk plus point-source model is the best representation of the data. We find that this point-source candidate moved from a position of sep. =

degrees between 2018 and 2021. Both of these positions are well within the ~13 au (~120 mas) disk gap, favouring the point-source interpretation. We explore the orbital parameter space that is consistent with the measured relative astrometry. We find orbits either with a similar orientation to the outer disk, with a high eccentricity e ≿ 0.65, or orbits with a large relative inclination (∼60°) to the outer disk, and any eccentricity. Despite the significance of the observed point-source signal, follow-up observations will be necessary to conclusively determine its nature.
A Pilot Study for the CSST Slitless Spectroscopic Quasar Survey Based on Mock Data
Authors: Pang Yuxuan , Wu Xue-Bing , Fu Yuming , Zhu Rui , Lyu Bing , Wang Huimei , Feng Xiaotong 
Published: February 2025

Abstract
The wide survey of the Chinese Space Station Telescope (CSST) will observe a large field of 17,500 deg2. The GU, GV, and GI grism observations of CSST will cover the wavelength range from 2550 to 10000 Å at a resolution of R ∼ 200 and a depth of about 22 AB magnitude for the continuum. In this paper, we present a pipeline to identify quasars and measure their physical properties with the CSST mock data. We simulate the raw images and extract the one-dimensional grism spectra for quasars, galaxies, and stars with r-band magnitudes of 18 < mr
< 22 using the CSST Cycle 6 simulation code (https://csst-tb.bao.ac.cn/code/csst_sim/csst-simulation). Using a convolution neural network, we separate quasars from stars and galaxies. We measure the redshifts by identifying strong emission lines of quasars. We also fit the 1D slitless spectra with QSOFITMORE to estimate black hole masses and Eddington ratios. Our results show that CSST slitless spectroscopy can effectively separate quasars with redshifts z = 0−5 from other types of objects with an accuracy of 99%. Among those successfully classified quasars, 90% of them could have precise redshift measurements with σ
NMAD = 0.002. The scatters of black hole masses and Eddington ratios from the spectral fittings are 0.13 and 0.15 dex, respectively. The metallicity diagnosis line ratios have a scatter of 0.1–0.2 dex. Our results show that the CSST slitless spectroscopy survey has the potential to discover about 0.9 million new quasars and provide important contributions to the science of active galactic nuclei and cosmology.

Abstract
On 2024 May 27, the Wide-field X-ray Telescope on board the Space Sciences, University of Chinese Academy of Einstein Probe (EP) mission detected enhanced X-ray emission from a new transient source in the Small Magellanic Cloud during its commissioning phase. Prompt follow-up with the EP Follow-up X-ray Telescope, the Swift X-ray Telescope. and NICER have revealed a very soft, thermally emitting source (kT ~ 0.1 keV at the outburst peak) with an X-ray luminosity of L ~ 4 × 1038 erg s−1, labeled EP J005245.1−722843. This supersoft outburst faded very quickly in a week's time. Several emission lines and absorption edges were present in the X-ray spectrum, including deep nitrogen (0.67 keV) and oxygen (0.87 keV) absorption edges. The X-ray emission resembles the supersoft source phase of typical nova outbursts from an accreting white dwarf (WD) in a binary system, despite the X-ray source being historically associated with an O9-B0e massive star exhibiting a 17.55 day periodicity in the optical band. The discovery of this supersoft outburst suggests that EP J005245.1−722843 is a BeWD X-ray binary: an elusive evolutionary stage where two main-sequence massive stars have undergone a common envelope phase and experienced at least two episodes of mass transfer. In addition, the very short duration of the outburst and the presence of Ne features hint at a rather massive, i.e., close to the Chandrasekhar limit, Ne–O WD in the system.
Magnetic Field Amplification during Stellar Collisions between Low-mass Stars

Published: February 2025

Abstract
Blue straggler stars in stellar clusters appear younger and bluer than other cluster members, offering a unique opportunity to understand the stellar dynamics and populations within their hosts. In the collisional formation scenario, excessive angular momentum in the collision product poses a challenge, as the consequent significant mass loss during transition to a stable state leads to a star with too low of a mass to be a blue straggler, unless it spins down efficiently. While many proposed spin-down mechanisms require magnetic fields, the existence or strength of these magnetic fields has not been confirmed. Here, we present 3D moving-mesh magnetohydrodynamical simulations of collisions between low-mass main-sequence stars and investigate magnetic field amplification. Magnetic field energy is amplified during collisions by a factor of 108–1010, resulting in the magnetic field strength of 107–108 G at the core of the collision product, independent of collision parameters. The surface magnetic field strengths increase up to 10–104 G. In addition, a distinctly flattened, rotating gas structure appears around the collision products in off-axis collisions, suggesting potential disk formation. These findings indicate that magnetic braking and disk locking could facilitate spin-down, enabling the formation of blue straggler stars.
Validation of Two Earth-mass Planets Orbiting GJ 1002
Authors: Castro Nieva Paula Andrea , Dodson-Robinson Sarah , Ramirez Delgado Victor 
Published: February 2025

Abstract
GJ 1002 is reported to host two Earth-mass planets in the habitable zone. We applied frequency-domain techniques for validating planet discoveries to the ESPRESSO and CARMENES radial velocity (RV) and cross-correlation full width at half maximum time series. Siegel’s test applied to Welch’s power spectrum estimates suggests that periodicity in the RV time series may not be statistically significant. The frequency response to a sinusoid with the frequency of planet b, or pseudowindow, shows excess power near the frequency of planet c. Finally, a Monte Carlo experiment where we create new RV time series realizations by adding white noise to original data reveals that the highest periodogram peak sometimes occurs at half the frequency of planet c. More extreme-precision observations are required to confirm RV oscillations and constrain the rotation period.
Taxonomic review of Korean Siphonaria species (Mollusca, Gastropoda, Siphonariidae)
Authors: Kim Yukyung , Park Jina , Hwang Ui Wook , Park Joong-Ki 
Published: February 2025

Many molluscan species exhibit a high degree of shell morphological plasticity in their shape (including sculptures), size and colour patterns, which can vary significantly depending on environmental conditions. These shell morphological variations make it challenging to differentiate species, based on morphology alone, often resulting in various taxonomic errors, such as misidentifications, overlooking cryptic species diversity or a plethora of nominal species. The genus Siphonaria constitutes a significant component of the macrobenthic invertebrate fauna in intertidal habitats across temperate to tropical regions. Given the limited attention to shell variation in previous taxonomic studies on the Korean Siphonaria species, the extensive range of ecophenotypic shell variations documented in this group raises questions about the taxonomic validity of previously reported Siphonaria species in Korea.
The present study provides a comprehensive taxonomic review of Korean Siphonaria species using a combination of shell morphology, radula structure and phylogenetic analysis of the mtDNA cox1 sequences. This integrative analysis confirmed the validity of S. acmaeoides, S. japonica and S. sirius in Korea, highlighting differences in shell and siphonal groove morphology amongst these species. Detailed descriptions of shell and radula characteristics, along with mtDNA cox1 sequences as DNA barcodes, are also provided, which are very useful for the accurate identification of Siphonaria species. Unlike these three Siphonaria species, the taxonomic validity of the four other species (S. coreensis, S. javanica, S. laciniosa and S. rucuana) previously reported from Korean waters is questionable, given their documented geographic distribution ranges and the potential misidentification of shell variants in Korean malacofaunal studies.

Published: February 2025

Background: Keratoconus has a global prevalence of 0.2 to 4790 per 100 000 persons and there is currently no published report about its incidence, prevalence or the role of optometrists in its management in Uganda. This study looked at the role of optometrists in the diagnosis, management and referral of patients with keratoconus in Uganda.Aim: To determine the knowledge, experiences and practices of optometrists in the management of keratoconus in Uganda.Setting: This study was conducted in Uganda.Methods: Fifteen optometrists who had practiced for at least one year were recruited into the study, which was conducted in accordance with the International Conference on Harmonisation Tripartite Guideline for Good Clinical Practice. The study involved interviews that were conducted over zoom and telephones, which were considered for participants who had internet challenges. The sessions were recorded, transcribed verbatim, coded and themes were derived.Results: The median number of years of experience was 7 years. The participants’ experiences were reported in terms of diagnosis, management and referral of patients with keratoconus and common themes were explored. Retinoscopy and Munson’s sign were the most common diagnostic methods while spectacles were the most common management option used by the optometrists.Conclusion: Most optometrists relied on retinoscopy for diagnosis and spectacles for the management of keratoconus because of the lack of diagnostic equipment and challenges associated with contact lens practice in Uganda.Contribution: This is the first study to explore how keratoconus is managed by optometrists in Uganda and the results can be used to improve patient care in the country.

Published: February 2025

Uniform resource locator (URL) defacement attack can be defined as any cyberattack in which the attacker replaces the appearance or content of the targeted webpage with their own that is intended to disgrace, mislead, or malign the website. Detecting URL defacement attacks is significant to avoid breaching the security of the website content or its configuration files, modifying the file locations, templates, or attacks on the website environment and applications. A machine learning (ML) technique can be used to detect the defacement attack on any website with complex content and structure, as opposed to the classical techniques for detection, such as Diff comparison, Document Object model tree analysis, and checksum, which can only be applied to static websites. This article proposes a feature selection model based on particle swarm optimization with support vector machine, decision tree, random forest, Naive Bayes, and k-nearest neighbor ML classification algorithms. The proposed model aims to improve the URL defacement attack detection by selecting the best features from the ISCX-URL-2016 dataset. Then, the reduced set of features produced by the proposed model step is used as input to evaluate and compare the results of the used ML classifiers. The results showed that the proposed model has significantly reduced the features, regarding the classification's feature reduction, the random forest classifier outperformed other classifiers in terms of true positive rates, accuracy, precision, sensitivity, and F-measure, whereas the proposed model with random forest classifier has 99.21% True positive rates, 99.29% accuracy rate, 99.38% precision rate, 99.21% sensitivity rate, and 99.29% F-measure rate. In the future directions of this article, more research should be done on a variety of things, including varying and sophisticated techniques of altering the URL defacement since it would better calibrate the model for application in real-life situations.

Vilnius beyond Urban vs Non-Urban Opposition: A Few Entry Points to the Planetary Urban Futures
Authors: Liubimau Siarhei 
Published: February 2025

The article analyzes Vilnius urban forest by applying the notion of planetarity and considering its implications for urban research. The author’s argument is delivered in three parts. The first part scrutinizes the difference between globalization and planetarity in a long-term perspective of social urban scholarship. The second part examines the significance of the vast amount of forest in Vilnius, as well as its lineage in the context of post-WWII urban growth. The third part regards the Karoliniškės Landscape Reserve as part of Vilnius green belt and as a potential opening in place of a former boundary, compatible with the earlier modern urban growth civic projects meant to replace the medieval city walls as “isolation belts.” Finally, the author discusses the Reserve’s three dimensions in the course of such opening—as more-than-urban heritage, non-human-centered public space, and a potential green commodification frontier.
