Published: February 2025

This project employs a form of LSTM networks as the special variant of Recurrent Neural Networks for producing musical compositions by learning from patterns in pitch, rhythm, and duration. A trained model on MIDI data produces a complete sequence given a seed, with this type of model always capable of producing stylistically coherent, creative outputs. Focus includes the fine-tuning parameters in such a way that there would be a minimal repetition and logical progression in compositions. The effectiveness of the approach may be assessed through quantitative criteria such as accuracy and loss, but also through feedback from listeners, which validates the capability of AI models to enrich music composition or creativity.

Published: February 2025

The teaching of argumentative writing in the English as a Foreign Language (EFL) classroom has become increasingly important as educators strive to enhance students' critical thinking and communication skills. This study analyzes current methodologies used in the teaching of argumentative writing, focusing on their effectiveness in fostering argumentative skills in EFL learners. A mixed-methods approach was employed, including a review of relevant literature and a survey of EFL instructors from different educational contexts. The findings revealed that, despite the wide use of traditional approaches such as the five-paragraph essay structure, more innovative strategies like task-based learning and collaborative writing activities have shown greater success in engaging students. These methodologies promote higher-order thinking skills, such as analysis, synthesis, and evaluation. However, challenges remain in integrating these methods into traditional EFL curricula, which often prioritize grammatical accuracy over fluency in writing. The study concludes that incorporating diverse and dynamic teaching strategies can significantly improve the quality of argumentative writing instruction in the EFL classroom.

Published: February 2025

This study analyzed the influence of the Intuitive-Imitative Approach on pronunciation instruction among English as a Foreign Language (EFL) students. The research was conducted using a mixed-methods approach, with a non-experimental descriptive design. A survey consisting of 20 Likert-scale items and three open-ended questions was administered to 83 university students. The validity of the instrument was confirmed through Cronbach's alpha coefficient (0.770) and expert review. The findings indicated that the Intuitive-Imitative Approach is widely applied in EFL classrooms. It was found that students predominantly use strategies based on imitation and repetition to improve their pronunciation, highlighting the importance of auditory exposure and repetitive practice. Additionally, the results revealed that instructors combine analytic-linguistic and intuitive-imitative approaches, prioritizing the use of audiovisual resources and interactive activities. It is concluded that pronunciation teaching through the Intuitive-Imitative Approach facilitates the natural acquisition of sounds and rhythms of the language, allowing students to develop a more authentic and intelligible pronunciation in English.

Authors: Dzuhriyan Ahmad Refi , Permana Surya Indra , Gufron M. Khaidir Ali
Published: February 2025

This study examines the legal protection of consumers in online business transactions in Indonesia, an issue that has become increasingly critical in the digital era. Advances in information technology have transformed traditional commerce into e-commerce, offering convenience while also introducing various risks, such as fraud, product non-conformity, and breaches of consumer data privacy. Employing a normative juridical method with a statutory approach, this research analyzes the implementation of Law No. 8 of 1999 on Consumer Protection and the Electronic Information and Transactions Law (ITE Law) in resolving e-commerce disputes.
The findings reveal that despite the existence of legal regulations, significant challenges persist in the implementation of consumer protection, primarily due to low consumer awareness of their rights and weak law enforcement. The novelty of this study, compared to previous research, lies in its empirical approach to identifying the legal challenges consumers face in online transactions. In addition to examining existing regulations, this study investigates real cases of e-commerce fraud in Indonesia that have led to financial losses for consumers.
The study underscores the importance of consumer education, stricter supervision of online business operators, and the development of more effective dispute resolution mechanisms. By highlighting the necessity of synergy between the government, business operators, and society, this research contributes to the formulation of more adaptive policies to strengthen consumer protection in the digital economy.
Enforcement of the Law Against Negligent Traffic Violators Resulting in Fatalities: A Case Study of Decision Number 34/Pid.B/2021/PN.Mgt
Authors: Istiawan Indah Ramadhani
Published: February 2025

Toll roads are constructed to connect distant locations, aiming to reduce travel time and facilitate mobility and transportation. However, the extended travel distances often result in driver fatigue and drowsiness, increasing the risk of traffic accidents. Law enforcement in cases of traffic accidents resulting in fatalities is an effort to uphold legal norms as guidelines for behavior in traffic and to maintain legal order in society. This study examines two main issues: (1) how law enforcement is carried out against negligent drivers responsible for fatalities and (2) the legal considerations of judges in adjudicating cases of fatal traffic negligence.
This study employs a normative juridical method with a statutory approach and qualitative normative analysis using inductive reasoning. Law enforcement against drivers causing fatal accidents involves investigations to collect evidence clarifying the crime and identifying suspects. In this case, the suspect was charged with violating Article 310 paragraph (4) and Article 312 of the Traffic and Road Transportation Law (LLAJ Law), carrying a maximum penalty of six years’ imprisonment and/or a fine of IDR 12,000,000, along with an additional penalty of up to three years’ imprisonment for further violations.
The findings reveal that the suspect was legally and convincingly proven guilty of negligence in driving, which resulted in an accident causing four fatalities. In their legal considerations, the judges emphasized the ultimum remedium principle as the basis for sentencing, while also taking into account aggravating and mitigating factors in issuing a verdict of three years and two months’ imprisonment. These findings highlight the challenges in enforcing traffic laws in Indonesia, including the low level of legal awareness among drivers and the lack of an effective preventive system to reduce accidents caused by negligence.

Published: February 2025

Background. Patients with end-stage chronic kidney disease (CKD) undergoing hemodialysis are at high risk for decreased bone mineral density (BMD), leading to osteopenia and osteoporosis. Various factors, including age, sex, menopausal status, and duration of hemodialysis, can influence BMD loss, necessitating early detection and management. Aim. To evaluate the correlation between risk factors – such as age, sex, menopausal status, and duration of hemodialysis – and decreased BMD in CKD patients undergoing regular hemodialysis, using dual-energy X-ray absorptiometry (DXA) as the diagnostic standard. Results. A cross-sectional study of 63 CKD patients (aged 18–70 years) found that 61.9% had osteopenia or osteoporosis at the lumbar spine, with over 70% affected at the hips. Significant correlations were identified between reduced lumbar BMD and both age (p=0.035) and menopausal status (p=0.018). Although longer hemodialysis duration and comorbidities such as hypertension and diabetes mellitus showed trends toward lower BMD, these associations did not reach statistical significance. Conclusion. Age and menopausal status are significant predictors of reduced BMD in CKD patients on hemodialysis. Routine DXA screening and targeted interventions are essential to mitigate fracture risk and improve patient outcomes.

We assess the impact of Ca ii

λ
λ5891, 5897 absorption arising in the interstellar medium (ISM) on the Sloan Digital Sky Survey-IV MaNGA Stellar Library (MaStar) and produce corrected spectroscopy for 80% of the 24,162-star catalog. We model the absorption strength of these transitions as a function of the stellar distance, Galactic latitude, and dust reddening based on high-spectral resolution studies. With this model, we identify 6342 MaStar stars that have negligible ISM absorption (W
ISM(Ca ii K) < 0.07 Å and W
ISM(Na i 5891) < 0.05 Å). For 12,110 of the remaining stars, we replace their Na i D profile (and their Ca ii profile for effective temperatures T
eff > 9000 K) with a coadded spectrum of low-ISM stars with similar T
eff, surface gravity, and metallicity. For 738 additional stars with T
eff > 9000 K, we replace these spectral regions with a matching ATLAS9-based BOSZ model. This results in a mean reduction in W(Ca ii K) (W(Na i D)) of 0.4–0.7 Å (0.6–1.1 Å) for hot stars (T
eff > 7610 K), and a mean reduction in W(Na i D) of 0.1–0.2 Å for cooler stars. We show that interstellar absorption in the simple stellar population (SSP) model spectra constructed from the original library artificially enhances W(Ca ii K) by ≳20% at young ages (<400 Myr); dramatically enhances the strength of stellar Na i D in starbursting systems (by ≳50%); and enhances stellar Na i D in older stellar populations (≳10 Gyr) by ≳10%. We provide SSP spectra constructed from the cleaned library and discuss the implications of these effects for stellar population synthesis analyses constraining the stellar age, [Na/Fe] abundance, and initial mass function.

Massive-star formation involves significant ionization in the innermost regions near the central object, such as gravitationally trapped H ii regions, jets, ionized disks, or winds. Resolved observations of the associated continuum and recombination line emission are crucial for guiding theory. The next-generation Very Large Array (ngVLA) will enable unprecedented observations of thermal emission with 1 mas resolution, providing a new perspective on massive-star formation at scales down to a few astronomical units at kiloparsec distances. This work presents synthetic interferometric ngVLA observations of the free–free continuum (93 GHz band), H41α, and H38α recombination lines from ionized jets and disks around massive protostars. Using the sf3dmodels Python package, we generate gas distributions based on analytical models, which are then processed through the RADMC-3D radiative transfer code. Our results indicate that the ngVLA can easily resolve, both spatially and spectrally, the ionized jet from a 15 M
⊙ protostar at 700 pc, distinguishing between collimated jets and wide-angle winds, and resolving their launching radii, widths, and any substructure down to a few astronomical units. Detailed studies of radio jets launched by massive protostars will be feasible up to distances of ​​​​​​∼2 kpc. Furthermore, ngVLA will be able to study in detail the ionized disks around massive (>10 M
⊙) protostars up to distances from 4 to 12 kpc, resolving their kinematics and enabling the measurement of their central masses across the Galaxy. These observations can be conducted with on-source integrations of only a few hours.

Ethanolamine (NH2CH2CH2OH) can form not only glycine directly under the conditions of proposed Archean alkaline hydrothermal vents, a possible environment for the origin of life, but also the polar hydrophilic head of phosphatidylethanolamine, the second most abundant phospholipid in cell membranes, under possible conditions of the primitive Earth. Recently, NH2CH2CH2OH was detected toward the G+0.693-0.027 molecular cloud. We construct the chemical network for NH2CH2CH2OH and its related species (HOCH2CN, CH3NH2, NH2OH, CH3OH, C2H5OH, and C2H3OH) via quantum chemical calculations, simulate their abundance evolutions with the pnautilus code, and then acquire the best-fitting shock-wave model for G+0.693: the combination of isothermal model I5 (T

We find NH2CH2CH2OH mainly comes from the thermal desorption produced by shock-induced heating and the photodesorption generated by cosmic-ray-induced UV photons; overall, its ice-phase species is mostly produced by four sequential ice-phase addition pathways, in which the final reactions are J-H + J-NH2CH2CHOH → J-NH2CH2CH2OH, J-H + J-NHCH2CH2OH → J-NH2CH2CH2OH, J-H + J-NH2CH2CH2O → J-NH2CH2CH2OH, and J-CH2OH + J-CH2NH2 → J-NH2CH2CH2OH. We also discuss the formation of HOCH2CN, CH3OH, C2H5OH, and C2H3OH in the best-fitting shock-wave model, as well as the formation of NH2CH2CH2OH in a typical hot-core model. Moreover, we predict NH2CH2CH2OH may be detected toward the newly formed hot core; the undiscovered species CH2CH2OH and HOCCNH are potentially detectable toward G+0.693.

Multiband photometric surveys provide a straightforward way to discover and classify astrophysical objects systematically, enabling the study of a large number of targets at relatively low cost. Here we introduce an alternative approach to select accreting white dwarf (AWD) candidates following their spectral energy distribution, entirely supported by the twelve photometric bands of the Southern Photometric Local Universe Survey (S-PLUS). The method was validated with optical spectroscopic follow-up with the Gemini South telescope, which unambiguously established ten systems as cataclysmic variables (CVs), alongside Swift X-ray observations of four of them. Among the ten CVs presented here are those that may be low-luminosity intermediate polars or WZ Sge-type dwarf novae with rare outbursts, two subclasses that can be easily missed in time-domain and X-ray surveys, the two methods currently dominating the discovery of new CVs. Our approach based on S-PLUS provides an important complementary tool to uncover the total population of CVs and the complete set of its subclasses, which is an important step toward a full understanding of close binary evolution, including the origin of magnetic fields in white dwarfs and the physics of accretion. Finally, we highlight the potential of S-PLUS beyond AWDs, serving other surveys in the characterization of their sources.

PSR B1310+18A is a 33 ms binary pulsar in a 256 day, low eccentricity orbit with a low-mass companion located in NGC 5024 (M53). In this Letter, we present the first phase-coherent timing solution for this pulsar (designated as M53A) derived from a 35 yr timing baseline; this combines the archival Arecibo Observatory data with the recent observations from the Five-hundred-meter Aperture Spherical radio Telescope. We find that the spin period derivative of the pulsar is between 6.1 and 7.5 × 10−19 s s−1, which implies a characteristic age between 0.70 and 0.85 Gyr. The timing solution also includes a precise position and proper motion for the pulsar, enabling the identification of the companion of M53A in Hubble Space Telescope data as a helium white dwarf (He WD) with a mass of

, confirming that the system formed recently in the history of the globular cluster. The system resembles, in its spin and orbital characteristics, similarly wide pulsar–He WD systems in the Galactic disk. We conclude by discussing the origin of slow pulsars in globular clusters, showing that none of the slow pulsars in low-density globular clusters are as young as the systems observed in the densest known globular clusters.
Cerebral salt wasting syndrome in a patient who suffered a gunshot traumatic head injury: a case report
Authors: Rojas-Urrea Alejandro , Arias-Mariño Daniela , García-Agudelo Lorena , Gonzalez-Calderon Ivan Camilo
Published: February 2025

Cerebral salt wasting syndrome is described as a hyponatremic condition in the context of a central nervous system injury. It is caused by a renal loss of sodium, and the primary distinguishing factor among similar conditions, such as the syndrome of inappropriate antidiuretic hormone secretion, is a reduction in the extracellular fluid volume. We describe here the case of a young adult who suffered brain injuries as a result of a gunshot and developed cerebral salt wasting syndrome during his in-hospital stay. Any type of cerebral attack can lead to hyponatraemic syndrome, but the most common are subarachnoid hemorrhages and neurological and meningeal tuberculosis infections. Treatment of the cerebral salt wasting syndrome leads to both hypovolemia and hyponatremia correction. The first line of management included hydric reposition with saline solution, either isotonic or hypertonic, depending on the severity of the symptoms.
Inappropriate polypharmacy during the COVID-19 pandemic: impact, challenges, and solutions – a narrative review

Published: February 2025

The COVID-19 pandemic has brought unprecedented challenges to healthcare systems worldwide, impacting various aspects of patient care. Polypharmacy, the concurrent use of multiple medications by a single patient, is a significant concern exacerbated by the pandemic. The dual threat of COVID-19 infection and polypharmacy for the same vulnerable group – the elderly and those with pre-existing multimorbidity – is particularly problematic, as polypharmacy has been shown to lead to suboptimal treatment outcomes in many chronic diseases. This comprehensive review explores the multifaceted issues surrounding polypharmacy during the COVID-19 pandemic, addressing its causes, consequences, and potential solutions.
A new psychrophilic yeast of Kriegeriaceae (Kriegeriales) isolated from lichen in the Arctic, with the description of Lichenia svalbardensis gen. et sp. nov.

Yeasts are an important component of the microbiome in circumpolar regions that are characterized by unique environmental conditions. However, the taxonomy of yeasts remains largely unknown in high- and low-latitude regions. Curing a field survey of yeasts in the Svalbard Archipelago, Norway, a new yeast genus in Kriegeriales was isolated from dendritic lichens. Based on the phylogeny of multiple loci (ITS, LSU, SSU, rpb1, rpb2, tef1-α, and cytb), morphology, and physiological characteristics, the new genus Lichenia is proposed with the type species Lichenia svalbardensis. Additionally, 10 °C and 15 °C are the fastest growth temperatures of L. svalbardensis. It has low or no growth at temperatures above 20 °C, and there appears to be a morphogenetic transition from yeast to pseudohyphae or hyphae above 10 °C.
Non-native species drive the global loss of freshwater fish beta-diversity

Freshwater ecosystems are facing mounting challenges. The widespread introduction of non-native species, for example, has resulted in the loss of native species and the substantial reconfiguration of diversity patterns across regions. Documenting such impacts remains critical for informing national-level biosecurity policies. Here, we explore changes in biogeographic patterns in freshwater fish diversity in response to the spread of non-native species, teasing apart the geographic (watersheds) and taxonomic (species) drivers of patterns at the global scale. We leveraged global databases of fish species occurrence to estimate the unique contributions of local watersheds and species (native and non-native origin) to beta-diversity for biogeographic domains. Beta-diversity metrics of watersheds and species at a domain scale can be interpreted as their importance for the uniqueness in freshwater fish composition. We report significant changes in freshwater fish beta-diversity in response to non-native species, with the largest impacts in the Ethiopian, Nearctic and Palearctic domains, even though non-natives decreased the contribution of watersheds to beta-diversity in all domains, particularly in watersheds with known impacts. Watersheds identified as most important for promoting beta-diversity were not evenly distributed across domains, were influenced by geographical isolation and their unique compositions were composed of many endemic and threatened species. Highest values of species contributions to enhancing beta-diversity were mainly observed for native and threatened species, although mean values of species contributions were higher for non-threatened species. Species from the most important watersheds had wide ecological tolerances, were, in general, natives, endemics and/or with IUCN threat status. Our findings underscore the widespread consequences of non-native species for shaping biogeographic patterns of freshwater fishes in the Anthropocene.

This short communication synthesizes biodiversity records of urban green spaces in Guatemala City. The research was conducted in the “Cinturón Ecológico Municipal”, or “Municipal Ecological Green Belt”, which consists of ravines covered with natural vegetation within Guatemala City. Available information from digital biodiversity platforms, previous studies and a short biological survey resulted in a checklist of 1688 terrestrial species, classified in 112 families of invertebrates (463 spp.), 77 families of vertebrates (348 spp.), 29 families of fungi (90 spp.), and 132 families of plants (787 spp.). A total of 113 species (7%) have some degree of vulnerability according to international and national lists of threatened species. The ongoing degradation of urban ecosystems demands urgent attention to increase biological surveys to support biodiversity conservation efforts and stricter protection measures as well as restoration of damaged areas.
