Published: December 2023

Developing highly active and durable air cathode catalyst is crucial but challenging for rechargeable zinc-air batteries (ZABs). Herein, a large-area, flexible, self-standing carbon membrane encapsulating adjacent Cu/Na dual-atom-sites catalyst is prepared by a scalable solution blow spinning combined pyrolysis strategy. The Cu-N-C site is inspired by the neighboring Na-containing functional group, which enhances O2 adsorption and optimizes the rate-determining step of O2 activation (*O2→*OOH) during the oxygen reduction reaction (ORR) process. Meanwhile, the Cu-N4 sites are encapsulated inside the carbon nanofibers and anchored by the carbon matrix to form a C2-Cu-N4 configuration, reinforcing the stability of the Cu centers. Moreover, the C matrix, anchored with a Na-containing functional group endows its outer shell C with negative charge, rendering the carbon skeletons less susceptible to corrosion by oxygen species and further preventing the dissolution of Cu centers. Under this multi-type regulations, ZAB with CuNa-CF catalyst as the air cathode demonstrates an unprecedentedly long charging/discharging stability for more than 5000 h with no noticeable decay. This remarkable stability improvement represents a critical step in developing Na-inspired Cu-N-C sites to overcome the durability barriers of ZABs for their future practical applications.

Published: December 2023

BackgroundHypotension is a common side effect of spinal anesthesia during caesarean delivery. To assess the association between preoperative femoral vessel variations and postural hypotension after spinal anesthesia for cesarean section.MethodsParticipants who scheduled to undergo elective cesarean section with spinal anesthesia between November 2020 and June 2021 were included in this prospective study. Hypotension was systolic blood pressure decreased by at least 20% from baseline.ResultsRight femoral artery (RFA) peak flow velocity and the percent variance in the right femoral vein (RFV) in the left lateral decubitus position (LP) were significantly higher in the hypotension group than in the normal blood pressure group (P = 0.04 and P = 0.01). The percent variance in the RFV diameter in the LP (OR = 76.796, P = 0.016), preoperative basal heart rate (OR = 1.043, P = 0.028) were risk factors associated with hypotension during cesarean section, and weight gain during pregnancy (OR = 0.915, P = 0.047) was protective factor associated with hypotension during cesarean section. A cutoff value of 0.059% for the percent variance in the RFV had an AUC of 0.627 (95% CI: 0.508–0.757, P = 0.0045). Another cutoff value of 15.75 kg for weight change during pregnancy had an AUC of 0.617 (95% CI: 0.510–0.724, P = 0.038).ConclusionsThe percent variance in RFV diameter, preoperative basal heart rate and weight gain during pregnancy may be associated with postural hypotension after spinal anesthesia for cesarean section and should pay more attention in the clinical setting.Trial registration:Chinese Clinical Trial Registry (ChiCTR2000040029, 18/11/2020).

Published: December 2023

In the process of mining the lower working face through the coal pillar (CP) in shallow-buried closely coal seams (SBCCS), noticeable roof step sinking and dynamic load effects on the support were observed. Taking the 22408 working face through the overlying concentrated CP of the Bulianta Coal Mine was selected as the research object. Used the methods of field measurement, physical simulation, and theoretical analysis to master the law of movement of the coal pillar and overlying strata while passing the CP, the structural coupling impact of the key strata structure of the interburden and coal pillar was revealed, which was the main reason for the cutting dynamic load effect during the passing of the CP of the working face. The advanced breaking mechanical model of the coupled roof structure of the "key strata structure of the interburden and the coal pillar" is established, and the main factors affecting the breakthrough distance of the advanced breaking distance are analyzed, and the mechanism of the strong weighting caused by the cutting roof of the working surface is explained at the stage of coal pillar. At the same time, it is obtained that when the width of the CP is 25m, the working face is 20m below the CP, which is the maximum bending moment point of the rock beam, indicating that the position that is prone to break under this width is about 5m of the coal pillar, which aligns with experimental data. The present study provides a theoretical guideline for the location and control of strong ground pressure during CP mining in SBCCS.

Published: December 2023

Except for addressing landfill requirements, incorporating recycled coarse aggregate into concrete development contributes to the creation of environmentally friendly and sustainable infrastructures. Moreover, among the variety of procedures used to reinforce and repair concrete structural elements, ferrocement confinement (FC) is a very adaptable approach. It stands out from many alternative approaches because of its exceptional features, which include affordability, ease of availability, and simplicity in production by common labor. The purpose of this research is to evaluate the effectiveness of incorporating FC into emerging nation construction methods. A detailed investigation was conducted to determine the effects of using FC wrapping on square-reinforced recycled aggregate concrete columns with different cross-sectional areas. Twenty-four carefully cast concrete column specimens in a range of diameters were put to axial compressive loads. Twelve sample were fabricated with recycled aggregate concrete and FC confinement while the other twelve samples were produced as control samples with natural aggerate concrete. The specimens were subsequently divided into four groups, each with a different size but the same slenderness ratio (1:6), to examine the effects of different column diameters on the benefits of ferrocement confinement. The stiffness of FC confined samples was improved by increasing the cross-sectional dimensions of the columns. The strength enhancement factor of confined samples was decreased by increasing the cross-sectional dimensions of the columns. The strength enhancement factor of confined sample 100 x 100 mm size was 2.33 Ks which reduced to 2.14, 2.05, and 1.95 Ks by increasing the side length of columns to 125 mm, 150 mm, and 175 mm, respectively. In addition, a cost-benefit analysis was carried out to emphasize how feasible and urgent it is for the construction sector to implement this technique right away.

Published: December 2023

The purpose of this paper is to explore the evolution behavior of two important laser features: the Bessel higher-order cosh-Gaussian (BHoChG) beam and the Bessel higher-order sinh-Gaussian (BHoShG) beam propagating through turbulent oceanic environments. Benefiting from the extended Huygens-Fresnel principle, the analytical formulas for the average intensity of the beams passing through oceanic turbulence are derived. The propagation of some laser beams through oceanic turbulence is also deduced as particular cases from the present study. The effects of oceanic turbulence parameters and the source beam parameters are examined to understand their influence on the intensity distribution of the considered beams by using numerical simulations. Our results show that the spreading of these beams depends on their initial parameters and oceanic parameters. Hence, the propagation of the studied beams through oceanic turbulent will be faster with the smaller dissipation rate of the mean square temperature, larger salinity fluctuations, higher rate of dissipation of turbulent kinetic energy per unit mass of fluid and with decreasing the beam width and the parameter Ω. The outputs of this study have useful applications in optical underwater communication, remote sensing, imaging and others.

Published: December 2023

With the increase in the quantity and quality of images that need to be processed, there are higher requirements for the speed of image processing. Thus, it is necessary to speed-up the image processing algorithms. In this paper, we design a quantum image edge detection algorithm based on Laplacian of Gaussian (LoG) operator, which has significant acceleration due to the quantum parallelism. Firstly, the quantum circuit of the novel enhanced quantum image representation (NEQR) model is improved to represent multiple quantum images simultaneously with lower time complexity. Secondly, the quantum subtractor and quantum comparator are optimized. Thirdly, quantum adder, quantum multiplier, quantum comparator, and quantum subtractor are adopted to design the quantum circuit of LoG operator and zero-crossing detector, which constitute the quantum edge detection algorithm. Finally, the algorithm is simulated on the IBM Quantum Experience (IBM Q) platform to verify its feasibility. Compared with the existing state-of-the-art algorithms, the proposed quantum image edge detection algorithm has significant improvement in time complexity.

Published: December 2023

In order to meet the requirements of the high efficiency for the wireless communication system, this paper introduces a high efficiency power amplifier (PA) based on the harmonic control technique. Compared with other works, this method can realize the second and third-harmonic impedance matching accurately. Besides, to avoid the problem of transmission line with high characteristic impedance in bias network, the π-typed and L-typed structure is utilized. For demonstration, a high efficient PA using CGH40010 GaN HEMT is designed and fabricated. The measured results show that it obtained an output power (Pout) of 39.5 ± 1 dBm, a Gain of 14.5 ± 1 dB, a maximum drain efficiency (DE) of 74.6% within the frequency range of 0.3–1.75 GHz. After comparison, this PA is superior in terms of efficiency and gain and has predominant engineer application.
Ice slabs thickening drives surface runoff expansion from the Greenland Ice Sheet’s percolation zone
Authors: Jullien Nicolas , Tedstone Andrew , Machguth Horst
Published: December 2023

Firn – an interannual layer made of a seasonal snow – covers the vast majority of the Greenland Ice Sheet. It holds the potential to buffer meltwater runoff contribution to sea level rise by storing it in its porous space. However, the ice sheet has recently experienced record summer melting, favouring the development of several meters thick low-permeability ice slabs when meltwater refreezes in the shallow firn. At the same time, surface runoff from the ice sheet has occurred at increasingly higher elevations. Using runoff limits retrieved from Landsat imagery and ice slab thickness derived from airborne Accumulation Radar onboard NASA’s Operation Ice Bridge, we show that the maximum visible runoff limit is controlled by the structure of the underlying firn. We demonstrate that there is heterogeneity in ice slab thickness which can be explained by lateral meltwater flow in the slush matrix and surface rivers overlying the slab, causing surface meltwater to refreeze some distance downslope of where it melted. Finally, comparing ice slab thickness with ice-sheet-wide Sentinel-1 Synthetic Aperture Radar Horizontal-Vertical polarisation signal strength, we show that the onset of visible meltwater runoff is associated with 2–4 m thick ice slabs, constraining the minimum ice thickness needed to sustain runoff. Our findings therefore provide a basis for making improvements to the parametrization of partitioning between meltwater refreezing and runoff in firn models, in turn reducing uncertainty in future sea level rise.

Published: December 2023

The increasing volume of large-scale assessment data poses a challenge for testing organizations to manage data and conduct psychometric analysis efficiently. Traditional psychometric software presents barriers, such as a lack of functionality for managing data and conducting various standard psychometric analyses efficiently. These challenges have resulted in high costs to achieve the desired research and analysis outcomes. To address these challenges, we have designed and implemented a modernized data pipeline that allows psychometricians and statisticians to efficiently manage the data, conduct psychometric analysis, generate technical reports, and perform quality assurance to validate the required outputs. This modernized pipeline has proven to scale with large databases, decrease human error by reducing manual processes, efficiently make complex workloads repeatable, ensure high quality of the outputs, and reduce overall costs of psychometric analysis of large-scale assessment data. This paper aims to provide information to support the modernization of the current psychometric analysis practices. We shared details on the workflow design and functionalities of our modernized data pipeline, which provide a universal interface to large-scale assessments. The methods for developing non-technical and user-friendly interfaces will also be discussed.

Authors: ARICI Özge , KUTLU Ömer
Published: December 2023

This study investigated the factors that are directly and indirectly related to collaborative problem-solving skills of students in Türkiye with multiple and multilevel mediation models, according to PISA 2015 results. The PISA 2015 Türkiye sample consisted of 5895 students. After missing data assignment and outlier analysis, the analyses were performed over the data set of 5882 students. In this study, whether the variables of valuing teamwork and valuing relationships show a mediation effect was tested with the Bootstrap method through multiple mediation models constructed with the dependent variable of collaborative problem-solving and the independent variables of school belonging and disciplinary climate. Our analyses revealed that the mediator variables had significant effects between school belonging and collaborative problem-solving. Similarly, the mediation effect between the disciplinary climate and the collaborative problem-solving was also significant. Multilevel mediation models constructed with the independent variables of students’ behavior hindering learning and extracurricular creative activities were analyzed with the multilevel structural equation modeling. The findings indicated that the variables of valuing relationships and valuing teamwork did not have a significant mediation effect between extracurricular creative activities and collaborative problem-solving scores. Similarly, it was found that the mediation effect between the students’ behavior hindering learning and collaborative problem-solving scores was not significant. In light of all these findings, it is recommended that school practices be strengthened to improve students' sense of belonging to school and a positive disciplinary climate, to develop students' collaborative problem-solving skills, and to improve attitudes towards collaboration.

Silver nanoparticle synthesis is an interesting area in nanotechnology due to their remarkable biomedicalproperties. To prepare silver nanoparticles, reduction of Ag+ ions to AgÂ° nanoparticles was done in a medium of Aloe vera. The AgNPs were synthesized by mixing extract and silver nitrate then heated at 80Â°C for 30 minutes maintaining alkaline pH10. The obtained colloidal solution was dried and taken to confirm the formation of silver nanoparticles through X-ray diffractometer. The average sizes of AgNPs were found to be in a range of 5 to 8 nm in controlled environment. The formation of smaller size silver nanoparticles was seen at higher concentration of extract (25gm/100ml), silver nitrate(4mM) and higher temperature (70Â°C to 80Â°C).The resulting silver nanoparticles were found to be effective against Staphylococcus aureusATCC 25923and Escherichia coliATCC 25922, Klebsiella pneumoniaeATCC 700603. However synthesized silver nanoparticles were observed less effective against Pseudomonas aeruginosaATCC 27853. The resulting silver nanoparticles showed a synergism of Aloe vera extract and silver nanoparticles on bactericidal effect.

The aim of the study was to assess the potential availability of mango by-products in Bobo-Dioulasso and Orodara, with a view to scaling up technologies for their valorization into animal feed. To this end, a cross-sectional survey was conducted among 24 drying units and 17 mango producers. The potential quantities of mango by-products and feed that could be produced were calculated. The results show that the potential quantities of mango by-products in the area were 7,857t for the units surveyed and 16,180t for those in operation. The potential quantities of feed that could be produced with these by-products were 4,190t and 8,427t for the surveyed and functional drying units respectively. Cumulative losses from orchards and drying units amounted to 38,994t, and the potential mango feed that could be produced was 19,486t. The potential nutritional supply from these feeds was 18,792t of dry matter (DM), 1,438t of digestible nitrogenous matter (DNM) and 21,547 UFFV. The surveys showed that mango processing and production by-products are available in the study area. Work is needed to scale up technologies for converting mango by-products into feeds that could be used for fattening. This would create added value for the mango sector, while increasing the availability of feed for animal production.

Osteochondromas are among the most common benign bone tumours with a male predilection which are usually incidentally detected. They are usually found in the metaphyseal region of long bones.This case is reported in view of the unique origin of the tumour in the diaphyseal region in a female. A woman came to the outpatient department with complaints of a painless, non mobile swelling over left distal femur for past 4 years.The swelling initially small gradually increased in size over 4 years but was not associated with pain or restriction of movements. Clinical examination revealed bony hard swelling in the anteromedial aspect of left distal femur not involving the knee joint. X ray showed a cauliflower shaped, pedunculated bony mass arising from the diaphyseal region of distal femur. MRI done was suggestive of osteochondroma. In order to confirm the diagnosis and to rule out malignant transformation,surgical excision and biopsy of the bony mass was performed. Histopathological reports confirmed the diagnosis of osteochondroma.

Background:The awareness and understanding of mental health services among primary caregivers of mentally ill patients are crucial for the well-being of both caregivers and patients. However, an awareness gap exists, hindering caregivers ability to access and utilize available mental health resources effectively. This gap is influenced by factors such as stigma, lack of education, and the complex nature of mental health services. Addressing this gap can lead to better patient outcomes, reduced caregiver burnout, more efficient resource allocation, and contribute to stigma reduction. Methods:A cross sectional survey method was used to collect the data using a structured awareness questionnaire from 100 caregivers of mentally ill patients based on non- probability purposive sampling.at Bapuji Hospital, Davangere. Results:Majority of the primary caregivers (72%) have inadequate level of awareness on mental health services and 28 % of primary caregivers had moderate level of awareness on mental health services. The binary logistic regression shows that educational status, previous exposure and source of awareness were significantly associated with the awareness level of mental health services. Conclusion:The findings underscore the urgent need for targeted education and outreach programs to bridge this gap. Addressing this issue can lead to improved access to essential mental health services and better overall outcomes for both patients and caregivers.
The determinants of audit report lag: Evidence from Indonesia
Authors: Endri Endri , Sari Dewi Santi , Eko Pramono Sigid
Published: December 2023

The determining factors that cause delays in audit reports are essential for shareholders to pay attention to when making quick decisions. Delays in audit reports receive significant attention in the capital markets where audited financial statements in annual reports are the only reliable source of information available to investors. This study aims to identify factors that cause delays in audit reports in the form of company and industry specifics consisting of profitability, company size, audit committee, audit opinion, and size of a public accounting firm. The research method uses a panel data regression model to test five hypotheses based on data collected from annual reports from 2011 to 2021. The research sample selected were 46 companies in the construction and property services sector listed on the Indonesian Sharia Stock Index. Empirical findings show that a public accounting firm’s profitability, audit opinion, and size hurt audit report lag, while the audit committee has a positive impact. Company size is the only factor that does not have an impact on audit reporting delays. The research results provide recommendations for company management and shareholders that delays in audit reports can be reduced by increasing company profits. Apart from that, audit delay lag can also be reduced by appointing a reputable or international public accounting firm and providing a quality audit opinion.

In this tutorial, some practical demonstrations are made using the DoE interface with real applications: (i) screening design for variable selection; (ii) optimization by Box-Behnken design; (iii) optimization by central composite design; (iv) factorial design for variable selection following by optimization with Doehlert design; (v) optimization by mixture design; (vi) optimization by mixture design with pseudocomponents; (vii) optimization by mixture design with process variable; and (viii) multiple-response optimization; also reproduced in the software Statistica v.13, StatSoft® for comparison. The GAMMA-GUI is constantly developing; suggestions for improvements or new ideas are welcome and can be directed to the developers.
Detecting Gravity-Related Misconceptions of First Year Medical Students Using the Newtonian Gravity Concept Inventory
Authors: Bani-Salameh Hisham
Published: December 2023

Misconceptions create their problems and must be clarified. One of the misconceptions that often arises is the concept of Newtonian gravity. In this report, we discuss first-year medical students’ understanding of the concept of gravity examined using the Newtonian Gravity Concept Inventory (NGCI). Four domains of the concept of gravity are covered by the NGCI utilizing 26 multiple-choice questions: Directionality, Gravity as a force, Independence from other forces, and threshold. One of the goals of this study is to evaluate the effectiveness of our teaching materials and methods. Therefore, the test was given to students twice as a pre and post-test relative to in-class gravity-related instructions. In this article, we’re reporting on gravity-related misconceptions found with our students in the pre-test only. 511 students participated in the test with a recorded average score of 39.9%. We documented a complete list of misconceptions with eleven dominant ones found in the pre-test: Gravity is affected by magnetism, Gravity is affected by objects’ density, misconceptions related to the dependence of the force of gravity on the distance, and more.
Analysis of Speed and Acceleration of Two Mobiles in the Study of One-dimensional Movement
Authors: Silva Jizreel Pereira da
Published: December 2023

The work discusses the analysis of the speed and acceleration of two mobiles in the study of one-dimensional movement as part of the study of kinematics, addressing in the classroom the experimental part, being projected on the board by the data show projector, where students individually, configure the system in order to observe the behavior of the blue and red furniture, comparing with the theoretical discussion also developed in the classroom. We address in an introductory way how the thinkers, philosophers, and scientists of the time of Mesopotamia and the Middle East dealt with the question of the movement of bodies and the mixture of what they believed about religion and mythology. The proposal of the operations in the simulator makes the students seek their questions and raise questions to colleagues and the teacher because, in addition to enriching the teaching-learning process, it motivates students for future proposals and consequently eases understanding of the functioning of physical theories. At the end of the simulation, we discuss the results, understanding what can change in the behavior of a mobile in front of the acceleration activation about the constant uniform movement.

A mobile laser scanner is a valuable tool to collect 3D information especially in urban regions, where vertical objects, like walls, poles and trees, need to be mapped. The collected point clouds can be used to segment objects and classify them according to their shape. Nevertheless, the segmentation and classification steps still need tools to analyze 3D point clouds. In this paper it is introduces a method to describe 3D shape from point clouds obtained by mobile laser scanner within the context of classification of urban furniture. The initial aim is to describe the 3D shape of objects located at the top of poles, but the approach can be extended to other objects. For this purpose, the distribution of the points is analyzed with help of the eigenvalues of the variance-covariance matrix. It is proposed the use of two parameters, one related to planarity and another to elongation, that are normalized in the range between zero and one, which allows easier description of the shape in terms of just two well-known terms.

Published: December 2023

This study aims to analyze the relationship between regional financial performance and inclusive economic development in Indonesia using secondary data from 34 provinces in Indonesia from 2011-2021. The data sources for this study were collected from the National Development Planning Agency, Directorate General of Fiscal Balance, and Statistics Indonesia. This study uses panel data regression analysis with a fixed effect model because it can reduce bias compared to other panel data models, especially those caused by unobservable time-invariant variables. The results showed that regional financial performance, as measured by the fiscal decentralization ratio, fiscal independence ratio, capital expenditure ratio, and social assistance expenditure ratio, significantly influenced inclusive economic development in Indonesia. Fiscal decentralization and social assistance spending have a positive relationship with inclusive economic development. Meanwhile, fiscal independence and capital expenditure have a negative relationship with inclusive economic growth.

Background

Although digital maternity records (DMRs) have been evaluated in the past, no previous work investigated usability or acceptance through an observational usability study.

Objective

The primary objective was to assess the usability and perception of a DMR smartphone app for pregnant women. The secondary objective was to assess personal preferences and habits related to online information searching, wearable data presentation and interpretation, at-home examination, and sharing data for research purposes during pregnancy.

Methods

A DMR smartphone app was developed. Key features such as wearable device integration, study functionalities (eg, questionnaires), and common pregnancy app functionalities (eg, mood tracker) were included. Women who had previously given birth were invited to participate. Participants completed 10 tasks while asked to think aloud. Sessions were conducted via Zoom. Video, audio, and the shared screen were recorded for analysis. Task completion times, task success, errors, and self-reported (free text) feedback were evaluated. Usability was measured through the System Usability Scale (SUS) and User Experience Questionnaire (UEQ). Semistructured interviews were conducted to explore the secondary objective.

Results

A total of 11 participants (mean age 34.6, SD 2.2 years) were included in the study. A mean SUS score of 79.09 (SD 18.38) was achieved. The app was rated “above average” in 4 of 6 UEQ categories. Sixteen unique features were requested. We found that 5 of 11 participants would only use wearables during pregnancy if requested to by their physician, while 10 of 11 stated they would share their data for research purposes.

Conclusions

Pregnant women rely on their medical caregivers for advice, including on the use of mobile and ubiquitous health technology. Clear benefits must be communicated if issuing wearable devices to pregnant women. Participants that experienced pregnancy complications in the past were overall more open toward the use of wearable devices in pregnancy. Pregnant women have different opinions regarding access to, interpretation of, and reactions to alerts based on wearable data. Future work should investigate personalized concepts covering these aspects.

UNSTRUCTURED

The effective management of chronic conditions requires an approach that promotes a shift in care from the clinic to the home, improves the efficiency of health care systems, and benefits all users irrespective of their needs and preferences. Digital health can provide a solution to this challenge, and in this paper, we provide our vision for a smart health ecosystem. A smart health ecosystem leverages the interoperability of digital health technologies and advancements in big data and artificial intelligence for data collection and analysis and the provision of support. We envisage that this approach will allow a comprehensive picture of health, personalization, and tailoring of behavioral and clinical support; drive theoretical advancements; and empower people to manage their own health with support from health care professionals. We illustrate the concept with 2 use cases and discuss topics for further consideration and research, concluding with a message to encourage people with chronic conditions, their caregivers, health care professionals, policy and decision makers, and technology experts to join their efforts and work toward adopting a smart health ecosystem.

Given the rapid development of digital mental health technologies and a focus on connecting with youth, there is an urgent need to enhance the engagement of young people with lived expertise in research. Even so, youth with lived experience of accessing mental health services are particularly affected by power imbalances and may receive limited compensation in academic settings. Therefore, an emphasis on how research engagement not only improves the work but can benefit young people themselves is required. Here, 5 young people with lived expertise report on their experience of being employed as researchers at the University of Sydney’s Brain and Mind Centre. As such, this team is uniquely placed to offer reflections from their work across multiple stages of research. This led to four key insights, including (1) creating accepting work cultures, (2) providing diverse opportunities for involvement, (3) giving young people agency and flexibility around sharing lived experiences, and (4) creating accommodating work environments for all researchers. We suggest that these insights can support more diverse ways of engaging young people and maximizing the value of participation for both researchers and young people themselves.
