Authors: Sethole Khethiwe Margaret , Mshunqane Nombeko , Kekana Mable 
Published: August 2023

Abstract
Introduction
What is known about checklists for interpreting chest radiographs? The question will guide the development of the inclusion criteria for the scoping review. Breaking down the scoping review question will allow the evaluation of inclusion and exclusion criteria for the protocol. The eligibility of the proposed research question will be assessed using the Population or Participants, Concept and Context (PCC) framework.

Background
X-ray reporting can be standardised using checklists. Checklists may reduce the time needed to produce a comprehensive X-ray report and improve the quality and consistency of detecting abnormalities on chest radiographs. This scoping review aims to map the available literature on what is known about checklists for interpreting chest radiographs.

Methods
We will follow the methodological framework for scoping reviews originally described by Arksey and O’Malley. The scoping review will include articles that describe checklists for reducing diagnostic errors, checklists for analysing chest radiographs, checklists for identifying abnormalities on chest radiographs and checklists for reporting chest radiographs in all settings. Search terms are chest radiographs, checklists, and chest X-rays. We will search for peer-reviewed articles and grey literature including dissertations and theses. We will search online databases including Ovid Medline and Ebscohost, to identify articles published in English from 1994 to 2022. The searched articles will undergo two levels of screening, first the title and abstract screening, then a full-text screening by two reviewers. Data from the selected articles will be extracted, using a tested extraction form and charted using the Joanna Briggs Institute guidelines.

Results
The results will be collated, summarised and discussed including any limitations of the included articles. The articles will be summarised in a table, as well as narratively. The distribution of studies will be summarised quantitatively and the numerical analysis will provide an overview and identify knowledge gaps. Content analysis will map different checklists available for chest interpretation.

Discussion
The results of the scoping review will be used to develop a checklist that will be used by medical doctors in collaboration with radiographers working in settings where there are no radiologists on-site, for interpreting chest radiographs.

φ-fixed point results for nonlinear contractions with an application
Authors: Hu Ju , Liu Xiao-lan , Sun Yan , Deng Jia , Zhang Huan 
Published: August 2023

AbstractIn this paper, using the notion ofw-distance in metric spaces, we introduce two types of nonlinear contractions,$(\iota ,\psi ,\varphi ,\phi ,p)$(ι,ψ,φ,ϕ,p)and rational-$(\iota ,\psi , \varphi ,\phi ,p)$(ι,ψ,φ,ϕ,p)contractions. Based on these contractions, we prove the existence and uniqueness of aφ-fixed point for the corresponding contraction. We also provide some examples to demonstrate the correctness and practicability of our results, along with a numerical experiment. Finally, we apply the obtained results to linear matrix equations and nonlinear Fredholm integral equations.
Short note on a solution with large amplitude for the limiting system arising from the competition-diffusion system
Authors: Kan-on Yukio 
Published: August 2023

AbstractThis paper is concerned with positive solutions of the limiting system arising from the Shigesada–Kawasaki–Teramoto model with large interspecific competition rate. It has previously been suggested that the limiting system has positive solutions with large amplitude for a certain value of parameters. As a first step, the purpose of this paper is to discuss the precise spatial profile of such solutions by employing formal calculations by the singular perturbation technique.
AI-empowered game architecture and application for resource provision and scheduling in multi-clouds
Authors: Yu Lei , Duan Yucong 
Published: August 2023

AbstractCurrent deep learning technologies used a large number of parameters to achieve a high accuracy rate, and the number of parameters is commonly more than a hundred million for image-related tasks. To improve both training speed and accuracy in multi-clouds, distributed deep learning is also widely applied. Therefore, reducing the network scale or improving the training speed has become an urgent problem to be solved in multi-clouds. Concerning this issue, we proposed a game architecture in multi-clouds, which can be supported by resource provision and service schedule. Furthermore, we trained a deep learning network, which can ensure high accuracy while reducing the number of network parameters. An adapted game, called flappy bird, is used as an experimental environment to test our neural network. Experimental results showed that the decision logic of the flappy bird, including flight planning, avoidance, and sacrifice, is accurate. In addition, we published the parameters of the neural network, so other scholars can reuse our neural network parameters for further research.
Technology adoption as survival strategy for small and medium enterprises during COVID-19
Authors: Mishrif Ashraf , Khan Asharul 
Published: August 2023

AbstractGlobally, operational capabilities of small and medium enterprises (SMEs) have been immensely affected by the COVID-19 pandemic, forcing many companies to use technology and innovation rather than the more traditional methods of operations. As the extent to which SMEs’ adoption of technological tools is still unknown, this study assesses the technological transformations and the challenges facing SMEs during the pandemic. It also evaluates the levels of customers satisfaction and future technological innovation plans in SMEs. Using quantitative and qualitative primary date, we empirically examine how COVID-19 lockdowns accelerated technology use in Omani SMEs and test eight hypotheses applying paired t test and Pearson’s correlation. Although the impact of the COVID-19 pandemic has been globally felt, this study focuses on the effect of the pandemic on SMEs operating in the logistics and supply chain sector in the Sultanate of Oman. The primary data used was collected through the survey questionnaire and interviews with business owners and company executives covering the period 2020–2021. The results show strong correlations between technology use before and during COVID-19; technology use during COVID-19 and in future; and technology use before COVID-19 and in future. They also reveal that technology adoption has been a successful persistence strategy during the pandemic and that highly digitized SMEs are more likely to adopt industry 4.0 technology. The findings are expected to have practical implications for policy making by investing and developing digital infrastructure to accelerate digital transformation, while company executives appreciating the requirements and benefits of adopting innovation and technology solutions to remain competitive. We acknowledge the limitation of our study to only SMEs in the Sultanate of Oman and within a short period of time during the COVID-19 pandemic. This makes it hard to generalize our findings; hence, we recommend further research in other business sectors and countries in the post-pandemic to corroborate our findings and compare outcomes. To the best of the authors' knowledge, no research has been done on SMEs that consider technological transformation during COVID-19. The study will advance knowledge of the development and adoption of technology in SMEs, as well as their impacts on productivity and efficiency.
Research and technology organizations as entrepreneurship instruments: the case of the Institut National d’Optique in the Canadian optics and photonics industry
Authors: Khelfaoui Mahdi , Bernier Luc 
Published: August 2023

AbstractResearch and technology organizations (RTOs) are studied in the innovation policy literature mainly as providers of R&D services and as intermediaries between universities and the private sector. Through the case of the Institut National d’Optique (INO), Canada’s leading RTO in the optics and photonics industry, we argue that RTOs can also act as entrepreneurs by generating technologies and commercializing them through licensing, technology transfers and spin-offs. By analyzing the broad range of activities undertaken by INO, we also discuss what characteristics make some RTOs more likely to embrace entrepreneurship than others. Those characteristics include the following: renewed access to government funding to build a strong in-house research infrastructure and scientific workforce; strategic R&D planning that incorporates commercial objectives and an environment that encourages a culture of entrepreneurship among employees; the ability to act as the driving force of a network of academic, government and private sector organizations. From a policy perspective, the INO case indicates that the main value of using RTOs as entrepreneurship instruments does not lie in profitability but rather in developing dynamic regional systems of innovation.

Published: August 2023

AbstractSmall and medium enterprises (SMEs) throughout the world are facing a very complicated crisis due to COVID-19 pandemic and other structural challenges. This study is aimed at demonstrating the challenges faced by SMEs, particularly the struggles that women entrepreneurs of SMEs in Indonesia experienced to survive against these structural issues: COVID-19, digital presence and the male-dominated business sector in the country. Focusing on female-owned businesses in Yogyakarta, Indonesia, this paper carefully considers how social media platforms helped these businesses to continue. Using a descriptive quantitative approach, we collected data from 130 respondents and found that the COVID-19 pandemic has severely affected women entrepreneurs—especially those operating small and medium enterprises. They have experienced reduced income due to decreased sales, disrupted supply chains, difficulty paying credit instalments, and lack of access to government assistances. This study further sheds light on social media’s important role in sustaining women-owned businesses. Facebook, WhatsApp, and Instagram have become the new tools through which women promote their products and reach new audiences. To overcome this issue, we advise a stronger government intervention to women-owned SMEs in the post-pandemic. Aside from managing social media for selling, we recommend women-owned small companies to internally intensify digital engagement, promotions, coupled by innovative products and attractive offers such as discounts.

Abstract
Background
Endometriosis is associated with systemic metabolic indicators, including body mass index (BMI), glucose metabolism and lipid metabolism, while the association between metabolic indexes and the occurrence and assisted reproductive technology (ART) outcome of endometriosis is unclear. We aimed to evaluate the characteristics of systemic metabolic indexes of endometriosis patients with infertility and their effects on pregnancy outcome after ART treatment.

Methods
A retrospective cohort study involve 412 endometriosis patients and 1551 controls was conducted. Primary outcome was metabolic indexes, and secondary measures consisted of the influence of metabolic indexes on the number of retrieved oocytes and ART outcomes.

Results
Endometriosis patients had higher insulin (INS) [6.90(5.10–9.50) vs 6.50(4.80–8.90) μU/mL, P = 0.005]. A prediction model for endometriosis combining the number of previous pregnancies, CA125, fasting blood glucose (Glu) and INS, had a sensitivity of 73.9%, specificity of 67.8% and area under curve (AUC) of 0.77. There were no significant differences in ART outcomes and complications during pregnancy. The serum levels of Glu before pregnancy were associated with GDM both in endometriosis group (aOR 12.95, 95% CI 1.69–99.42, P = 0.014) and in control group (aOR 4.15, 95% CI 1.50–11.53, P = 0.006).

Conclusions
We found serum Glu is related to the number of retrieved oocytes in control group, serum INS is related to the number of retrieved oocytes in endometriosis group, while serum Glu and INS before pregnancy are related to the occurrence of GDM in two groups. A prediction model based on metabolic indexes was established, representing a promising non-invasive method to predict endometriosis patients with known pregnancy history.

Abstract
Background
With the development of whole-genome sequencing technology, non-invasive prenatal testing (NIPT) has been applied gradually to screen chromosomal microdeletions and microduplications that cannot be detected by traditional karyotyping. However, in NIPT, some false positives and false negatives occur. This study aimed to investigate the applicability of extended NIPT (NIPT-PLUS) in the detection of chromosomal aneuploidy and microdeletion/microduplication syndrome (MMS).

Methods
A total of 452 pregnancies that underwent prenatal diagnostic testing (amniocentesis or chorionic villus sampling) by chromosomal microarray analysis (CMA), were screened by NIPT-PLUS from the peripheral blood sample of the pregnant women. The results of the two tested items were compared and analysed.

Results
Of the 452 cases, 335 (74.12%) had positive CMA results, and 117 (25.88%) had no abnormal results. A total of 86 cases of trisomy 21, 18 and 13 and sex chromosome aneuploidy (SCA) were detected by CMA and NIPT-PLUS, with a detection rate of 96.51% (83/86). Among them, the detection rates of T18, T13; 47, XXY; 47, XXX and 47 XYY were 100%, and the detection rates of T21 and 45 XO were 96.55% and 90%, respectively. The detection sensitivity of rare chromosomal trisomy (RAT) was 80% (4/5). The positive predictive values of NIPT-PLUS for chromosome aneuploidy T21, T18 and T13 and for SCA and RAT were 90.32%, 87.50%, 25.00%, 88.89% and 50%, respectively. A total of 249 cases (74.32%) of chromosomal MMS were detected by CMA. The detection rate of NIPT-PLUS was 63.86% (159/249), and 90 cases (36.14%) were missed. The larger the MMS fragment, the higher the NIPT-PLUS detection sensitivity. In addition, most small fragments were of maternal origin.

Conclusion
The comparison between the CMA and NIPT-PLUS techniques shows that NIPT-PLUS has high sensitivity for detecting chromosomal aneuploidy and chromosomal copy number variations (CNVs) with fragments > 5 M. However, the sensitivity of CNV for fragments < 5 M is low, and the missed detection rate is high. Additionally, confined placental mosaicism and foetal mosaicism are the key factors causing false negatives in NIPT-PLUS, while maternal chromosomal abnormalities and confined placental mosaicism are key contributors to false positives, so appropriate genetic counselling is especially important for pregnant women before and after NIPT-PLUS testing.
Unveiling the mechanism of remote epitaxy of crystalline semiconductors on 2D materials-coated substrates
Authors: Wang Xuejing , Choi Joonghoon , Yoo Jinkyoung , Hong Young Joon 
Published: August 2023

AbstractRemote epitaxy has opened novel opportunities for advanced manufacturing and heterogeneous integration of two-dimensional (2D) materials and conventional (3D) materials. The lattice transparency as the fundamental principle of remote epitaxy has been studied and challenged by recent observations defying the concept. Understanding remote epitaxy requires an integrated approach of theoretical modeling and experimental validation at multi-scales because the phenomenon includes remote interactions of atoms across an atomically thin material and a few van der Waals gaps. The roles of atomically thin 2D material for the nucleation and growth of a 3D material have not been integrated into a framework of remote epitaxy research. Here, we summarize studies of remote epitaxy mechanisms with a comparison to other epitaxy techniques. In the end, we suggest the crucial topics of remote epitaxy research for basic science and applications.

Abstract
Background
Over the past decades, there has been a growing international interest in user involvement in healthcare research. However, evidence on the management and impact of patient and public involvement in Nordic healthcare research remains limited.

Objective
The aim was to explore and delineate the current state, practice, and impact of patient and public involvement in healthcare research across different areas of healthcare and patient populations in the Nordic countries.

Methods
We conducted a scoping review using nine scientific databases and gray literature from 1992–2023. Sources were categorized as empirical or non-empirical. We used the Guidance for Reporting Involvement of Patients and the Public Short Form 2 checklist for reporting of patient and public involvement in healthcare research and the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews.

Results
A total of 56 publications were included, consisting of 39 empirical and 17 non-empirical sources. Gray literature varied among countries and institutions encompassing different types of documents. We found an increase in the number of publications on patient and public involvement in Nordic healthcare research. This was evidenced by the growing number of references and institutional initiatives intended at involving the public, indicating the increasing emphasis on patient and public involvement in Nordic healthcare research. The terminology used to describe patient and public involvement varied over time. However, there has been a gradual narrowing down of terms as the concept of PPI has become more integrated into research practices, particularly with the involvement of funding agencies.

Conclusion
The utilization of patient and public involvement in Nordic healthcare research has substantially increased, proliferated, and gained widespread acceptance across diverse healthcare domains. The variety of approaches challenged our scoping review in terms of systematic description and impact. Patient and public involvement was applied in one or more research stages using different methodologies and terms. International agreement on terms and definitions is needed for reliable interpretation of the use of patient and public involvement in Nordic healthcare research.

Published: August 2023

Abstract
Background
Implant-supported dentures have become an essential means of restoring occlusal function after jaw reconstruction. Bone mineral density (BMD) may influence the success rate of implant denture restorations. This study aimed to explore whether the Hounsfield unit (HU) value can be used to monitor the changing trend of fibular BMD after jaw reconstruction.

Results
A total of 54 patients who underwent maxillar/mandibular reconstruction with a fibula flap were included in this study. There was a significant correlation between the HU value and BMD at 1 week, 3 months, and 6 months after surgery, and both were significantly correlated with follow-up time. The difference between each pair of absorption rates (DAR) was less than 10% in 66.7% and 75.9% of patients at 3 and 6 months; however, the DAR was more than 20% in 12% and 13.8% of patients at 3 and 6 months, respectively.

Conclusions
There is a significant correlation between HU value and BMD. The HU value can be used to roughly reflect the fibular BMD changing trend in a group of patients as opposed to an individual, and the HU value is not equivalent to BMD.

Authors: Gumisiriza Hannington , Olet Eunice Apio , Mukasa Paul , Lejju Julius B. , Omara Timothy 
Published: August 2023

Abstract
Background
Malaria remains a major global health challenge and a serious cause of morbidity and mortality in sub-Saharan Africa. In Uganda, limited access to medical facilities has perpetuated the reliance of indigenous communities on herbal medicine for the prevention and management of malaria. This study was undertaken to document ethnobotanical knowledge on medicinal plants prescribed for managing malaria in Rukungiri District, a meso-endemic malaria region of Western Uganda.

Methods
An ethnobotanical survey was carried out between May 2022 and December 2022 in Bwambara Sub-County, Rukungiri District, Western Uganda using semi-structured questionnaire. A total of 125 respondents (81 females and 44 males) were randomly selected and seven (7) key informants were engaged in open interviews. In all cases, awareness of herbalists on malaria, treatment-seeking behaviour and herbal treatment practices were obtained. The ethnobotanical data were analyzed using descriptive statistics, informant consensus factor and preference ranking.

Results
The study identified 48 medicinal plants belonging to 47 genera and 23 families used in the treatment of malaria and its symptoms in the study area. The most frequently cited species were Vernoniaamygdalina, Aloevera and Azadirachtaindica. Leaves (74%) was the most used plant organ, mostly for preparation of decoctions (41.8%) and infusions (23.6%) which are administered orally (89.6%) or used for bathing (10.4%).

Conclusions
Indigenous knowledge of medicinal plants used as prophylaxis and for treatment of malaria still exist among the local communities of Bwambara Sub-County. However, there is a need to investigate the antimalarial efficacy, phytochemical composition and safety of species (such as Digitariaabyssinica and Berkheyabarbata) with high percentage use values to validate their use.
