Published: February 2024

AbstractThe reactive melt flow emerges as an important factor for diversification of basaltic magmatic reservoirs, but whether and how it influences continental arc basaltic mushes are enigmatic. Here, we used mineral and whole-rock geochemistry to examine the petrogenesis of a suit of mafic and intermediate plutons in western Yangtze Block, which were emplaced at continental arc crust and primarily had plagioclase and clinopyroxene as early cumulate mineral phases. We found the crystal mushes were infiltrated by externally-derived reactive melt with high δ18O and fertile crustal signatures, resulting in the changes of mineral phases (e.g., clinopyroxene transformed to hornblende) and bulk-rock geochemistry (including isotopes). Then, the reacted granitic melt was prone to either be extracted from or stall in the crystal mushes, generating quartz-poor (mafic) or quartz-rich (intermediate) plutons, respectively. This study supports the reactive melt infiltration may serve as an important engine for compositional diversity of basaltic mush system within continental arc settings.
ArtProtect: Blockchain and NFC‐based anti‐counterfeit system for physical art
Authors: Tantowibowo Cindy Handoko , Yau Wei‐Chuen 
Published: February 2024

AbstractCounterfeit artwork presents a significant risk to copyright holders and the economy. Without expertise in art, it is not straightforward to distinguish an artwork counterfeit from a genuine piece. This work designs and implements a reliable solution that enables users with near‐field communication‐enabled Android smartphones to verify artwork authenticity by accessing its respective certificate of authenticity stored in the Ethereum blockchain. To represent a physical artwork, the artwork image and metadata are stored in an inter‐planetary file system and minted as an ERC721 non‐fungible token to a smart contract deployed in Ethereum Rinkeby Testnet. The mobile app ArtProtect was developed to generate certificate of authenticity based on each non‐fungible token fetched through OpenSea Testnet API. Users access this information by scanning an near‐field communication tag embedded into the artwork. The content of the tag is signed by the respective artwork's artist and responsible agent by using Ethereum signing with their Ethereum wallet accounts. Through testing and analysis, the implemented work is secure, tamper‐evident, usable, flexible, and inexpensive to be applied to a real‐world scenario.

Context.NGC 1566 is a local face-on Seyfert galaxy and is known for exhibiting recurrent outbursts that are accompanied by changes in spectral type. The most recent transient event occurred from 2017 to 2019 and was reported to be accompanied by a change in Seyfert classification from Seyfert 1.8 to Seyfert 1.2.Aims.We aim to study the transient event in detail by analyzing the variations in the optical broad-line profiles. In particular, we intend to determine the structure and kinematics of the broad-line region.Methods.We analyzed data from an optical spectroscopic variability campaign of NGC 1566 taken with the 9.2 m Southern African Large Telescope (SALT) between July 2018 and October 2019 triggered by the detection of hard X-ray emission in June 2018. We supplemented this data set with optical to near-infrared (NIR) spectroscopic archival data taken by VLT/MUSE in September 2015 and October 2017, and investigated the emission from different line species during the event.Results.NGC 1566 exhibits pronounced spectral changes during the transient event. We observe the emergence and fading of a strong power-law-like blue continuum as well as strong variations in the Balmer, He I, and He IIlines and the coronal lines [Fe VII], [Fe X], and [Fe XI]. Moreover, we detect broad double-peaked emission line profiles of O Iλ8446 and the Ca IIλλ8498, 8542, 8662 triplet. This is the first time that genuine double-peaked O Iλ8446 and Ca IIλλ8498, 8542, 8662 emission in AGN is reported in the literature. All broad lines show a clear redward asymmetry with respect to their central wavelength and we find indications for a significant blueward drift of the total line profiles during the transient event. The profiles and the FWHM of the Balmer lines remain largely constant during all observations. We show that the double-peaked emission line profiles are well approximated by emission from a low-inclination, relativistic eccentric accretion disk, and that single-peaked profiles can be obtained by broadening due to scale-height-dependent turbulence. Small-scale features in the O Iand Ca IIlines suggest the presence of inhomogeneities in the broad-line region.Conclusions.We conclude that the broad-line region in NGC 1566 is dominated by the kinematics of a relativistic eccentric accretion disk. The broad-line region can be modeled to be vertically stratified with respect to scale-height turbulence with O Iand Ca IIbeing emitted close to the disk in a region with high (column) density, while the Balmer and helium lines are emitted at greater scale height above the disk. The observed blueward drift might be attributed to a low-optical-depth wind launched during the transient event. Except for this wind, the observed kinematics of the broad-line region remain largely unchanged during the transient event.

Published: February 2024

Context.An optically thick, geometrically thin accretion disk (AD) around a supermassive black hole might contribute to broad-line emission in type 1 active galactic nuclei (AGN). However, the emission line profiles are most often not immediately consistent with the profiles expected from a rotating disk. The extent to which an AD in AGN contributes to the broad Balmer lines and high-ionization UV lines in radio-loud (RL) AGN needs to be investigated.Aims.This work aims to determine whether the AD can account for the double-peaked profiles observed in the Balmer lines (Hβ, Hα), near-UV (MgIIλ2800), and high-ionization UV lines (C IVλ1549, CIII]λ1909) of the extremely jetted quasar3C 47.Methods.The low ionization lines (LILs) (Hβ, Hα, and Mg IIλ2800) were analyzed using a relativistic Keplerian AD model. Fits were carried out following Bayesian and multicomponent nonlinear approaches. The profiles of prototypical high ionization lines (HILs) were also modeled by the contribution of the AD, along with fairly symmetric additional components.Results.The LIL profiles of3C 47agree very well with a relativistic Keplerian AD model. The disk emission is constrained between ≈102and ≈103gravitational radii, with a viewing angle of ≈ 30 degrees.Conclusions.The study provides convincing direct observational evidence for the presence of an AD and explains that the HIL profiles are due to disk and failed-wind contributions. The agreement between the observed profiles of the LILs and the model is remarkable. The main alternative, a double broad-line region associated with a binary black hole, is found to be less favored than the disk model for the quasar3C 47.

The Cost of Developing and Implementing an Antepartum Referral Program for Penicillin Allergy Evaluation at a Single Academic Tertiary Care Hospital
Authors: Burn Martina S. , Xu Xiao , Kwah Jason , Liao Jane , Son Moeun 
Published: February 2024

Objective Approximately 10% of pregnant individuals report a penicillin allergy, yet most are not truly allergic. Allergy verification during pregnancy is safe and recommended; however, many hospitals lack the infrastructure to execute testing. Our aim was to evaluate the cost of developing and implementing a penicillin allergy referral program for pregnant individuals at an academic institution and to compare costs of care between patients who were referred and not referred through the program.
Study Design We conducted an economic analysis of our institution's antepartum penicillin allergy referral program. We prospectively collected detailed resource utilization data and conducted the analysis from the program's perspective, accounting for costs related to program development, allergy verification, antibiotic cost, and delivery hospitalization. Costs were compared between patients who were referred for evaluation versus patients who were not referred using bivariate tests as well as quantile regression adjusting for baseline differences. A sensitivity analysis was performed for allergy testing cost. All cost estimates were inflation adjusted to 2021 U.S. dollars.
Results The startup cost of program development and educational initiatives was $19,920, or 86 per patient. The median allergy evaluation cost was $397 (interquartile range: $303–663). There was no significant difference in maternal (median: $13,579 vs. 13,999, p = 0.94) or neonatal (median: $3,565 vs. 3,577, p = 0.55) delivery hospitalization cost or antibiotic cost (median: $1.57 vs. 3.87, p = 0.10) between referred and nonreferred patients. Overall, the total cost per person did not differ significantly between study groups (median: $18,931 vs. 18,314, p = 0.69).
Conclusion The cost of developing a penicillin allergy referral program in pregnancy was modest and did not significantly alter short-term cost of care with potential for long-term cost benefit. Verification of a reported penicillin allergy is an integral part of antibiotic stewardship, and the pregnancy period should be utilized as an important opportunity to perform this evaluation.

Authors: Patil Shruti S. , Devani Kavin K. , Lemle Swapnil D. 
Published: February 2024

AbstractPenetrating brain injuries are rare events in modern times. In this article we present the case of an adolescent with a knife, lodged in the occipital region needing surgical care. The patient was conscious, cooperative, and vitally stable with a Glasgow coma scale (GCS) of 15/15 with no lateralizing signs. Computed tomography (CT) scan of the brain demonstrated the knife blade in the suboccipital bone with suspicious injury to the right transverse sinus. General anesthesia was provided and airway secured in a lateral position using a video laryngoscope. Surgery was performed in the prone position using the Mayfield head holder. All measures to prevent secondary brain injury were taken. The patient remained vitally stable during surgery and could be extubated after surgery. Planning and preparation are vital for the smooth conduct of the case.

Abstract
Objective To compare the effects of strength training with load progression after 4 weeks on sleep parameters and mental health in college students.
Methods A total of 17 university students (11 women, 6 men), ranging from 18 to 21 years old, were randomized into a strength training group (STG) and a control group (CG). The Pittsburgh sleep quality index (PSQI), insomnia severity questionnaire, hospital anxiety and depression (HAD) scale, profile of mood states (POMS), and chronotype were used to evaluate the main outcomes. Training consisted of 60 minute·d−1 (2 times/week, for 4-weeks), with 3 sets of 10 to 12 repetitions, and a 1-minute rest interval between sets and exercises. Baseline and postintervention differences were analyzed using generalized estimating equations (GEE).
Results After 4 weeks of ST, a significant time effect on the chronotype (β: 1.33; p < 0.05) was observed in the STG. Additionally, there was a significant time and group effect in the reduction of tension (β: 5.00; p < 0.05), depression (β: 15.41; p < 0.05), anger (β: 8.00; p < 0.05), and confusion (β: 6.50; p < 0.05). For fatigue (β: 2.66; p < 0.05), there was a significant time effect difference in its reduction. Vigor was meaningfully increased in the STG group (β: −1.75; p < 0.05). Furthermore, a significant positive relationship was observed between sleep quality and anxiety (r = 0.54; p = 0.03). Finally, insomnia was positively related with an increase in confusion (r = 0.70; p = 0.04) and anxiety (r = 0.52; p = 0.04), as well as with a decrease in vigor (r = −0.71; p = 0.03).
Discussion Short-term strength training for 4 weeks was effective for improving mental health, helping achieve characteristics of a positive mood profile, that is, low values for negative factors and a high value for the positive factor.
Intensive Voice Treatment following Botulinum Neurotoxin Injection for a Speaker with Abductor Laryngeal Dystonia: An Exploratory Case Study
Authors: Schnell Mindy , Slavin Dianne 
Published: February 2024

AbstractAbductor laryngeal dystonia (ABLD) is a rare neurological voice disorder which results in sporadic opening of the vocal folds during speech. Etiology is unknown, and to date there is no identified effective behavioral treatment for it. It is hypothesized that LSVT LOUD®, which was developed to treat dysphonia secondary to Parkinson's disease, may have application to speakers with ABLD to improve outcomes beyond that with botulinum neurotoxin (BoNT) treatment alone. The participant received one injection of BoNT in each vocal fold 2 to 3 months prior to initiating intensive voice therapy via teletherapy. Objective measures of vocal loudness (dB sound pressure level), maximum phonation time, and high/low pitch frequency (Hz) were recorded in all treatment sessions and follow-up sessions. Over the course of treatment, the participant showed steady gains in phonation time, volume, pitch range, and vocal quality with a substantial reduction in aphonic voice breaks by the end of the treatment program. Perceptual symptoms of ABLD were nearly undetectable by the participant and the clinicians up to 12 months posttreatment, with no additional BoNT injections. The results suggest that LSVT LOUD® following BoNT was effective, with long-lasting improvement in vocal function, for this speaker with ABLD.
How do intra-party dynamics impact the party elite’s immigration policy manoeuvres? The case of German Social Democrats
Authors: Orhan Suat Alper 
Published: February 2024

AbstractThis article examines the Social Democratic Party of Germany’s (SPD) approach to immigration and the role of party activists in shaping its policies. The article delves into the party’s response to the 2015 refugee crisis and its aftermath, utilising the discourse taken by the party’s leading figures and interviews with party elites, exploring their perceptions of activists and their constraints on immigration policies. The findings reveal that the influence of party activists is beyond their official power within the organisational structure, and their nestedness within the party affects the party elite’s policy- and decision-making on immigration. Given the potential backlash from activists, the study underscores the party elites’ cautious approach to policy shifts and emphasises the significance of leadership skills, the party’s image and electoral motivations in navigating intra-party dynamics and policy-making. Ultimately, the research highlights the delicate balance SPD elites seek in addressing immigration issues within its party structure.

Published: February 2024

AbstractEducational strategies have undergone significant transformations in an era marked by rapid globalization, advancements in communication technologies, and challenges like the COVID-19 pandemic. Amid these changes, Citizen Science (CS) has gained prominence as an innovative educational approach, particularly in fostering complex thinking skills necessary to navigate contemporary global trends. This study aims to fill the knowledge gap regarding the effectiveness of CS projects in developing complex thinking competencies within higher education. Through a bibliometric analysis of 28 Scopus-indexed articles from 2000 to 2022, this research maps the landscape of CS as an educational strategy and evaluates its alignment with complex thinking development. The analysis indicates a strong link between CS projects and the enhancement of complex thinking and its sub-competencies. It demonstrates that CS initiatives have successfully achieved their educational objectives, substantially enriching the learning experience. Furthermore, the research highlights a growing trend in applying CS for educational purposes. These findings suggest that CS can be a valuable component of higher education curricula, offering a practical method for developing critical competencies in students. The study underscores the potential of CS to contribute meaningfully to the evolution of pedagogical practices and provides a foundation for future research to build upon, particularly in the context of higher education’s response to global educational demands.

Published: February 2024

Tantalum thin films sputtered on unheated silicon substrates are characterized with microwaves at around 10 GHz in a 10 mK environment. We show that the phase of tantalum with a body-centered cubic lattice (α-Ta) can be grown selectively by depositing a niobium buffer layer prior to a tantalum film. The physical properties of the films, such as superconducting transition temperature and crystallinity, change markedly with the addition of the buffer layer. Coplanar waveguide resonators based on the composite film exhibit significantly enhanced internal quality factors compared with a film without the buffer layer. The internal quality factor approaches 2 × 107 at a large-photon-number limit. While the quality factor decreases at the single-photon level owing to two-level system (TLS) loss, we have deduced that one of the causes of TLS loss is the amorphous silicon layer at the film–substrate interface, which originates from the substrate cleaning before the film deposition rather than the film itself. The temperature dependence of the internal quality factors shows a marked rise below 200 mK, suggesting the presence of TLS–TLS interactions. The present low-loss tantalum films can be deposited without substrate heating and thus have various potential applications in superconducting quantum electronics.
Dark matter effects explanation with the torsion in the Minkowski space
Authors: Romanets Petro 
Published: February 2024

Abstract
Investigating rotation curves and the Tully–Fisher ratio within galaxies represents a central theme of extensive research and scientific interest. Despite several theoretical models, a comprehensive explanation of the observed correlation between galaxy types and their rotation curves remains elusive. This study endeavors to bridge this knowledge gap by delving into the discernible connection between the presence of dark matter and galaxy classification. By meticulously examining the gravitational field’s dependency on its source’s point symmetry, we introduce a novel theoretical framework that offers a coherent rationale for these empirical findings. Our proposed model explains the appearance of dark matter as a direct consequence of the reduction of point symmetry in gravitational systems. Neither arbitrary systems with a high mass density nor a perfectly spherically symmetric mass distribution give the observable effects of dark matter. Special attention was paid to the axial symmetry scenario as a reasonable approach for modeling the mass distribution in most galaxies. We thoroughly analyzed, showing strong agreement with experimental observations for dwarf, Sb, and Scd galaxies. Thus, our study provides a compelling theoretical foundation for elucidating the intricate interplay between galaxy types, rotation curves, and the presence of dark matter, shedding new light on the dynamics of the cosmos.

In this paper, a restricted transverse ray transform acting on vector and symmetric m-tensor fields is studied. We developed inversion algorithms using restricted transverse ray transform data to recover symmetric m-tensor fields in

. We restrict the transverse ray transform to all lines going through a fixed curve γ that satisfies the Kirillov–Tuy condition. We show that the known restricted data can be used to reconstruct a specific weighted Radon transform of the unknown vector/tensor field’s components, which we then use to explicitly recover the unknown field.
Recent progress in epitaxial growth of dislocation tolerant and dislocation free III–V lasers on silicon
Authors: Yan Zhao , Li Qiang 
Published: February 2024

Abstract
Epitaxial integration of III–V optical functionalities on silicon (Si) is the key to complement current Si photonics, facilitating the development of scalable, compact photonic integrated circuits. Here we aim to outline this field, focusing on the III–V semiconductor materials and the III–V lasers grown on Si. This paper is divided into two main parts: in the first part, we discuss III–V materials grown on Si, including the low-index {hhl} facets, (001) Si surface and anti-phase boundary, and dislocation engineering. The second part centres at III–V lasers grown on Si: we will first discuss III–V lasers that are highly tolerant to dislocations, including quantum dot/dash diode lasers, interband cascade, and quantum cascade lasers grown on Si from near infrared to long-wave infrared. We then move to the selective heteroepitaxy of low dislocation density III–Vs for the bufferless lasers. Finally, we review the III–V nanowire photonic crystal lasers grown on Si, which offers a different approach to overcome material mismatch and grow dislocation free III–V structures on silicon. We start with briefly introducing the recent progress of each technology, followed with a discussion of its key advantages, research challenge and opportunities.
