Authors: Seong Junhwa , Jeon Youngsun , Yang Younghwan , Badloe Trevon , Rho Junsuk 
Published: November 2023

AbstractOptical metasurfaces consisting of two-dimensional nanostructures have rapidly developed over the past two decades thanks to their potential for use as optical components, such as metalenses or metaholograms, with ultra-compact form factors. Despite these rapid developments, major challenges for the commercialization of metasurfaces still remain: namely their mass production and use in real-life devices. A lot of effort has been made to overcome the limitations of electron beam lithography which is commonly used to fabricate metasurfaces. However, a breakthrough in mass production is still required to bring the cost of metasurfaces down into the price range of conventional optics. This review covers deep-ultraviolet lithography, nanoimprint lithography, and self-assembly-based fabrication processes that have the potential for the mass production of both cost-effective and environmentally friendly metasurfaces. We then discuss metalenses and future displays/sensors that are expected to take advantage of these mass-produced metasurfaces. The potential applications of mass-produced optical metasurfaces will open a new realm for their practical applications and commercialization.

Published: November 2023

AbstractThe gas pressure in front area of heading face is essential to dynamically evaluate coal and gas outburst during coal mining. In this work, a novel inversion model of gas pressure in front area of the heading face was established on premise of the hypothesis that a time-dependent zone of steady flow exists within newly exposed face. The key parameters in the inversion model were obtained based on the gas emission models and field data of gas emission rate in different times, which were used to calculate the volumes of gas emission from different sources. The results show that the percentage of gas emission from the heading face, coal wall and collapsed coal ranges from 7% to 47%, 47% to 82% and 2% to 11%, respectively. Based on the calculated volumes of gas emission and gas pressure inversion model, the gas pressure was obtained and transformed to the gas content. The absolute errors between the gas content tested and transformed in every hour is 0.4%–33%, which proved the rationality of gas pressure inversion model. Furthermore, the daily drifting footage, the radius of gas pressure boundary and the gas permeability coefficient of coal seam were confirmed to have a great effect on the result of gas pressure inversion. The inversion results verify that the speedy excavation can increase the risk of coal and gas outburst. This work produces a useful method for gas disaster prevention and control that converts the gas emission rate to an index of gas pressure within coal seam.

AbstractSupported nanoparticles have attracted considerable attention as a promising catalyst for achieving unique properties in numerous applications, including fuel cells, chemical conversion, and batteries. Nanocatalysts demonstrate high activity by expanding the number of active sites, but they also intensify deactivation issues, such as agglomeration and poisoning, simultaneously. Exsolution for bottom-up synthesis of supported nanoparticles has emerged as a breakthrough technique to overcome limitations associated with conventional nanomaterials. Nanoparticles are uniformly exsolved from perovskite oxide supports and socketed into the oxide support by a one-step reduction process. Their uniformity and stability, resulting from the socketed structure, play a crucial role in the development of novel nanocatalysts. Recently, tremendous research efforts have been dedicated to further controlling exsolution particles. To effectively address exsolution at a more precise level, understanding the underlying mechanism is essential. This review presents a comprehensive overview of the exsolution mechanism, with a focus on its driving force, processes, properties, and synergetic strategies, as well as new pathways for optimizing nanocatalysts in diverse applications.
Effectiveness and conduct of macroprudential policy in Indonesia in 2003–2020: Evidence from the structural VAR models
Authors: Dąbrowski Marek A. , Widiantoro Dimas Mukhlas 
Published: November 2023

AbstractThe paper examines the effectiveness of macroprudential policy in Indonesia and policy reactions to economic developments. Using the structural vector autoregression and data on the regulatory LTV ratio, we investigate the policy effectiveness in controlling credit growth and real property prices along with the effects on economic activity. We find that the LTV-based policy in Indonesia is effective in taming credit growth in the medium run. It, however, is not the case with real property prices whose response to policy changes is counterintuitive and resembles the price puzzle found in the studies on monetary policy. Moreover, our results lend moderate support to the effect of LTV policy on economic activity, especially in the non-COVID-19 sample. We also show that the LTV policy in Indonesia is conducted in an active and circumspective way. In a series of robustness checks, we demonstrate that the results hold when the ordering of variables is changed, alternative proxies for macroprudential policy, output gap, and financial conditions are employed, or the sample is limited to the non-COVID-19 period.

Published: November 2023

AbstractAdditive manufacturing technologies can produce complex components in a more efficient and environmentally sustainable way when compared with conventional manufacturing technologies. These advantages are expected to keep cementing Additive manufacturing role in several industries. Additive manufacturing technologies are fast-improving technologies with an estimated doubling of performance on average every five years. These fast developments make it difficult to keep track of current technological capabilities and environmental impacts. Among the most relevant additive manufacturing technologies there are the metal additive technologies of Powder Bed Fusion, Directed Energy Deposition and Binder Jetting. This paper assesses the current technological capabilities and environmental impact of these technologies. For that, resorting to data from literature, technical reports and company data sheets, the technological steps are defined, the relevant process parameters are established, and qualitative and quantitative data is gathered. A set of visualizations of process capabilities and their environmental impact is performed with the intent of helping designers and engineers with decision-making. It is also interesting for the research community to visualize and understand the current capabilities and to establish roadmaps for research. Limitations of this study include data currently available for each parameter, and the shortage of data for the environmental calculations.

AbstractIn this work, some transparent aluminum sodium borate-based glasses containing Dy2O3 have been prepared using the melt quenching method. The incorporation of Dy3+ ions in the glass network leads to increase and decrease the density and molar volume, respectively. The structural properties are investigated by XRD and FTIR spectroscopy. It is revealed that addition of Dy2O3 causes a conversion of boron coordination from BO4 to BO3, which indicates the increase in the number of non-bridging oxygen. Therefore, the optical band gap is found to decrease as the Dy3+ ions content increases. The temperature dependences of dielectric constant and AC conductivity are studied at different frequencies. The electric conductivity and dielectric parameters decrease with increasing Dy3+ content due to the decrease in Na+ ions mobility due to the blocking effect of Dy3+ cations in the glass network. The shielding factors have been evaluated for the prepared glasses with the help of Phy-X program. The maximum linear attenuation coefficient (LAC) is found at 0.284 MeV and varied between 0.125 and 0.140 cm−1. The results revealed that the incorporation of Dy2O3 into the glasses has a substantial effect on the Zeff.. The value of the Zeff for the D1 sample, which does not include any Dy2O3, stays relatively the same, ranging around 7.51. We found that the rate of reduction in Zeff was significantly high when the energy of the photons is smaller than 0.826 MeV. From the Zeff data, we found that the addition of Dy2O3 to the glasses improves both their capacity to absorb and their capability to scatter ionizing radiation.

Abstract
Adhesives play a crucial role in many industries, including medicine, construction, and electronics. In the medical field, additives may be incorporated into adhesives to enhance drug delivery or prevent infection. This study explored the effects of two antimicrobial ceragenin (CSA) additives, CSA-44 and CSA-131, on the shear strength of a polyacrylate pressure sensitive adhesive. Strength of the adhesive bond was determined by lap shear tests. The adhesive formulation with CSA-131 exhibited significantly higher shear strength, 84.5 N, compared to the formulation with CSA-44 or the neat adhesive, 22.5 and 19.5 N, respectively. Preliminary analysis suggests that the longer hydrocarbon chains in CSA-131 enhance van der Waals forces, leading to improved adhesion to the nonpolar substrate. These findings shed light on possible molecular design principles for optimizing the properties of adhesive formulations.

Article highlights

Two antimicrobial additives were shown to have no negative impact on the performance of a medical adhesive.

One additive, CSA-131, improved the shear strength of the adhesive formulation relative to the neat adhesive.

Differences in shear strength of the adhesive formulation are likely linked to the molecular structure of the additives.

Abstract
Background
Although back pain may be present in subjects with adolescent idiopathic scoliosis (AIS), its natural history is unknown. Therefore, this study evaluated the incidence of back pain in scoliotic adolescents longitudinally.

Methods
This retrospective analysis examined prospectively collected pain subscale data of the Scoliosis Research Society questionnaire between the initial presentation and up to 3 years of follow-up. Consecutive subjects with AIS aged 10–18 at baseline managed by observation within the study period were included. Study subjects with at least one time point of follow-up data were considered. Alternatively, a group with physiotherapy-treated was also included for comparison.

Results
We enrolled 428 subjects under observation. The incidence of back pain among study subjects was 14.7%, 18.8%, and 19.0% for the first year, second year, and third year of follow-up, respectively. Most experienced mild pain (1 out of 5 points) throughout the study. Neither incidence nor intensity of pain significantly differed between subjects under observation and received physiotherapy. Additionally, study subjects with a new onset of back pain had poorer function, self-image, and mental health scores than those without pain.

Conclusion
We investigated the incidence of back pain longitudinally in subjects suffering from AIS. Further validation of the current results is warranted.
Situation awareness in Sweden’s emergency medical services: a goal-directed task analysis

Published: November 2023

AbstractSituation awareness is knowing what is going on in the situation. Clinicians working in the emergency medical services (EMS) encounter numerous situations in various conditions, and to be able to provide efficient and patient safe care they need to understand what is going on and possible projections of the current situation. The design of this study encompassed a Goal-Directed Task analysis where situation awareness information requirements were mapped in relation to goals related to various aspects of the EMS mission. A group of 30 EMS subject matter experts were recruited and answered a web-based survey in three rounds related to what they though themselves or a colleague might need to achieve situation awareness related to the specific goals of various situations. The answers were analysed using content analysis and descriptive statistics. Answers reached consensus at a predetermined level of 75%. Those who reached consensus were entered into the final goal-directed task analysis protocol. The findings presented that EMS clinicians must rely on their own, or their colleagues prior experience or knowledge to achieve situation awareness. This suggests that individual expertise plays a crucial role in developing situation awareness. There also seems to be limited support for situation awareness from organizational guidelines. Furthermore, achieving situation awareness also involves collaborative efforts from the individuals involved in the situation. These findings could add to the foundation for further investigation in this area which could contribute to the development of strategies and tools to enhance situation awareness among EMS clinicians, ultimately improving patient care and safety.

AbstractGalaxy gas kinematics are sensitive to the physical processes that contribute to a galaxy’s evolution. It is expected that external processes will cause more significant kinematic disturbances in the outer regions, while internal processes will cause more disturbances for the inner regions. Using a subsample of 47 galaxies ($0.27<z<0.36$) from the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, we conduct a study into the source of kinematic disturbances by measuring the asymmetry present in the ionised gas line-of-sight velocity maps at the$0.5R_e$(inner regions) and$1.5R_e$(outer regions) elliptical annuli. By comparing the inner and outer kinematic asymmetries, we aim to better understand what physical processes are driving the asymmetries in galaxies. We find the local environment plays a role in kinematic disturbance, in agreement with other integral field spectroscopy studies of the local universe, with most asymmetric systems being in close proximity to a more massive neighbour. We do not find evidence suggesting that hosting an Active Galactic Nucleus contributes to asymmetry within the inner regions, with some caveats due to emission line modelling. In contrast to previous studies, we do not find evidence that processes leading to asymmetry also enhance star formation in MAGPI galaxies. Finally, we find a weak anti-correlation between stellar mass and asymmetry (i.e., high stellar mass galaxies are less asymmetric). We conclude by discussing possible sources driving the asymmetry in the ionised gas, such as disturbances being present in the colder gas phase (either molecular or atomic) prior to the gas being ionised, and non-axisymmetric features (e.g., a bar) being present in the galactic disk. Our results highlight the complex interplay between ionised gas kinematic disturbances and physical processes involved in galaxy evolution.
RADIOCARBON DATING AND FRESHWATER RESERVOIR EFFECTS OF AQUATIC MOLLUSKS WITHIN FLUVIAL CHANNEL DEPOSITS IN THE MIDWESTERN UNITED STATES

Published: November 2023

ABSTRACTLate Quaternary fluvial channel deposits are notoriously difficult to date. In the midwestern United States, shells of aquatic mollusks can be found within many fluvial channel sediments and therefore can be radiocarbon (14C) dated to determine the age of the deposits. However, carbonate platform rocks are abundant in this region, potentially causing freshwater 14C reservoir effects (FRE) in mollusk shells. We 14C dated 11 aquatic gastropod and bivalve shell samples from specimens collected live from a stream in southwestern Ohio during three different years to assess the modern 14C reservoir effect. Modern samples yielded an average 14C FREmodern of 518 ± 65 14C yrs for 2020 (n=5), 640 ± 34 14C yrs for 2021 (n=2), and 707 ± 76 14C yrs for 2022 (n=4). We also 14C dated matched pairs of organic wood or charcoal and aquatic mollusk shells from late Pleistocene and Holocene deposits in the Four Mile Creek floodplain to determine the FREfossil. These samples, free of any potential influence from nuclear bomb testing, yielded an overall weighted mean FREfossil of 1029 ± 345 14C yrs. We then assess the advantages and limitations of both the FREmodern and FREfossil methods for determining freshwater reservoir effects. Finally, we apply the FREfossil correction to a series of shell ages from fluvial terrace deposits as a case study. The results indicate that although there is a 14C FRE in streams from the midwestern United States, aquatic shells can provide robust age control on fluvial channel deposits. More research is needed to understand the spatial and temporal variability of FREs, as well as any species effects, among various watersheds across the midwestern United States.

AbstractThe link between school feeding programmes (SFP) and the promotion of healthy eating and health is being explored in studies performed in different countries. The coronavirus disease-19 pandemic has revealed flaws and weaknesses in contemporary food systems, with many school-age children experiencing food insecurity and hunger. There is intense debate among policymakers regarding whether government SFP should be universal or targeted. Countries such as Brazil and India, which have two of the most comprehensive universal free-of-charge programmes, have shown the benefits of SFP, including improved nutritional status, support for more sustainable food systems, attendance and academic performance. Evidence shows and supports actions advocating that it is time to offer healthy and free school meals for all students.

AbstractCystic echinococcosis (CE) remains a significant challenge in Uganda with precise status largely undocumented in most communities. To determine CE prevalence, post-mortem examination was done on 14 937 livestock (5873 goats, 1377 sheep, 3726 zebu cattle and 3054 Ankole cattle) slaughtered in abattoirs in the districts of Moroto in Karamoja region, Kumi in Teso region and Nakasongola and Luwero in Buganda region. The overall CE prevalence was 21.9% in sheep, 15.2% in zebu cattle, 5.5% in goats and 2.1% in Ankole cattle. Moroto district had a higher prevalence of CE than other districts with 31.3% in zebu cattle, sheep 28%, goats 29.1% and (0%) in Ankole cattle. On organ locations, the lungs were the most affected in all livestock in all the study areas. Considering cyst fertility, 33.9, 1.7 and 6.4% of Ankole cattle, sheep and zebu cattle respectively had fertile cysts in the liver while 4.5% of goats and 4% Ankole cattle had fertile cysts in the lungs. In conclusion, CE is widespread and occurs among cattle, sheep and goats in pastoral and agro-pastoral areas in Uganda. Therefore, there is an urgent need to create awareness among the communities on role of livestock in CE epidemiology and transmission.

AbstractObjective:Subtle changes in memory, attention, and spatial navigation abilities have been associated with preclinical Alzheimer disease (AD). The current study examined whether baseline AD biomarkers are associated with self- and informant-reported decline in memory, attention, and spatial navigation.Method:Clinically normal (Clinical Dementia Rating Scale (CDR®) = 0) adults aged 56–93 (N = 320) and their informants completed the memory, divided attention, and visuospatial abilities (which assesses spatial navigation) subsections of the Everyday Cognition Scale (ECog) annually for an average of 4 years. Biomarker data was collected within (±) 2 years of baseline (i.e., cerebrospinal fluid (CSF) p-tau181/Aβ42 ratio and hippocampal volume). Clinical progression was defined as CDR > 0 at time of final available ECog.Results:Self- and informant-reported memory, attention, and spatial navigation significantly declined over time (ps < .001). Baseline AD biomarkers were significantly associated with self- and informant-reported decline in cognitive ability (ps < .030), with the exception of p-tau181/Aβ42 ratio and self-reported attention (p = .364). Clinical progression did not significantly moderate the relationship between AD biomarkers and decline in self- or informant-reported cognitive ability (ps > .062). Post-hoc analyses indicated that biomarker burden was also associated with self- and informant-reported decline in total ECog (ps < .002), and again clinical progression did not significantly moderate these relationships (ps > .299).Conclusions:AD biomarkers at baseline may indicate risk of decline in self- and informant-reported change in memory, attention, and spatial navigation ability. As such, subjectively reported decline in these domains may have clinical utility in tracking the subtle cognitive changes associated with the earliest stages of AD.
