Published: January 2022

Abstract
Background
The global research shows that people suffer from a variety of sleep disorders and human actions are the result of neuronal function inside his brain, the feedback of this function can be received and processed as a signal emitted from the surface of the skull. EEG device can receive and record brain signals. Researchers have used a variety of methods to obtain and pre-process signals, extract and reduce the characteristics and types of classifiers in various studies. Research shows that there are three general states of wakefulness (stage 1 + REM sleep) and (stage 2 + deep sleep) separated by the EEG signal.
Methods
The study was performed in accordance with the PRISMA guidelines. A total of 740 articles were found from scientific literature databases (PubMed, Scopus, Web of Science and Wiley Online Library ). After all exclusions, a final total of 64 articles were included in this review. The randomized controlled trials that have assessed at least one therapeutic outcome measured before and after intervention were included in the final analysis.
Results
A total of 64 studies were identified at the screening step. In the identification phase, total of 11 records were excluded from the further assessment and 53 records were entered into the screening phase in which Clinical Trial, Review, Books, Editorial were excluded from the review. In the eligibility stage, 49 records remained in the study where total of 34 studies were included for detailed review. Due to the heterogeneities in the available variables as well as the target aspects, the authors decided to review the studies comprehensively.
Conclusions
However, due to some concerns about its effectiveness, more targeted experiments are needed to identify more accurate targets and pathways responsible for the metabolism of its brain signals.
The material ratio of roadside backfill body based on spatiotemporal law of ground pressure: a case study of Xingtai Mine, China
Authors: Zhao Xinyuan , Li Xinwang , Yang Ke , Cheng Lichao , Qin Yiling 
Published: January 2022

Abstract
The material ratio of the roadside backfill body in gob-side entry retaining determines its mechanical properties, which plays an important role in the supporting effect of the roadway surrounding rock. In this paper, a similar material modeling is used to verify the spatiotemporal law of the ground pressure in the engineering case of dense solid backfilling mining in Xingtai Mine, China. Based on that law, the theoretical requirements for the bearing performance of the roadside backfill body are proposed. Finally, a material ratio that meets the theoretical requirements is obtained by compression test, and the deformation and failure characteristics of the backfill body with this ratio are analyzed. The results show that the maximum pressure of the backfill body measured in Xingtai Mine is 5.5 MPa, which is about 40 m away from the coal face, after 40m, the pressure of the backfill body will not increase anymore. The similar simulation test also proved that the ground pressure behind the coal face increases gradually and tends to be stable during the backfilling process, which shows certain spatiotemporal characteristics. Through the proportioning experiment, it is determined that the optimal material ratio of the roadside backfill body is gangue: fly ash: cement = 10:3:1, which meets the theoretical requirement that the strength of the roadside backfill body at any position is not less than the ground pressure at that position. The research results provide a reference for the engineering practice of gob-side entry retaining in dense backfilling mining.
Stability of Fixed Points in an Approximate Solution of the Spring-Mass Running Model
Authors: Wróblewska Zofia , Płociniczak Łukasz , Kowalczyk Piotr 
Published: January 2022

Abstract
We consider a classical spring-mass model of human running which is built upon an inverted elastic pendulum. Based on our previous results concerning asymptotic solutions for large spring constant (or small angle of attack), we construct analytical approximations of solutions in the considered model. The model itself consists of two sets of differential equations - one set describes the motion of the centre of mass of a runner in contact with the ground (support phase), and the second set describes the phase of no contact with the ground (flight phase). By appropriately concatenating asymptotic solutions for the two phases we are able to reduce the dynamics to a onedimensional apex to apex return map. We find sufficient conditions for this map to have a unique stable fixed point. By numerical continuation of fixed points with respect to energy, we find a transcritical bifurcation in our model system.MSC 2020 Classification: 34C20, 34D05, 37N25, 70K20, 70K42, 70K50, 70K60
Short- and Long-Term Impact of a Multifaceted Approach Targeting Fluoroquinolone use in a Tertiary, Non-Teaching Hospital
Authors: Belsky Brianna , Minson Quentin 
Published: January 2022

Abstract
Background. While various strategies for antibiotic restrictions have been validated, their impacts are not well described in smaller, non-teaching facilities. Fluoroquinolones are an appropriate target for restriction based on their propensity for overuse and potential for causing “collateral damage.” Aim. Evaluate the impact of a multifaceted approach to decreasing fluoroquinolone use on fluoroquinolones and alternative antibiotics at a smaller, non-teaching facility. Method. Retrospective, interrupted time series analysis conducted at a single 288-bed, tertiary, non-teaching hospital with 71 adult ICU beds comparing antibiotic consumption measured monthly by defined daily doses per 1000 adjusted patient days (DDD/1000 APD) prior to intervention (January 2011 to August 2014) to short-term (October 2014 to December 2015) and long-term (January 2018 to December 2019) periods following intervention. Results. An increase in downward trends of fluoroquinolone use was observed from prior to intervention (-0.49 DDD/1000 APD) to the short-term period (-1.13 DDD/1000 APD) and to a greater extent in the long-term period following the intervention (-1.32 DDD/1000 APD). Fluoroquinolone consumption decreased from 100.20 DDD/1000 APD in August 2014 to 73.96 DDD/1000 APD in the short-term and 14.89 DDD/1000 APD in the long-term intervention period. Levofloxacin susceptibility for Pseudomonas aeruginosa increased from 61% in 2014 to 83% in 2018. No deleterious effects on Pseudomonas aeruginosa susceptibilities were observed for alternative antibiotics. Conclusion. A multifaceted approach to decreasing fluoroquinolone use at a smaller, tertiary, non-teaching hospital led to a sustained decrease in consumption and a substantial increase in levofloxacin susceptibility to Pseudomonas aeruginosa.

Published: January 2022

Abstract
Background: Although Clear-cell carcinoma has been found in various organs as a variant of ductal carcinoma of the pancreas, it still hasn’t been well recognized. According to the WHO classification, primary Clear-cell carcinoma of the pancreas is rare, and it is classified as a “miscellaneous” carcinoma. To date it has been poorly characterized and only few cases have been reported in the literature [1]. Case presentation: We report here an unusual case of Clear-cell carcinoma in a 59-year-old man involving the head of the pancreas and the second part of the duodenum initially misconceived as pyloric gland adenoma, a rare duodenal entity. Nevertheless, duodenal sub stenosis was suspected of malignancy, so further investigations were made. Subsequent abdominal computed tomography (CT) detected not only a duodenal vegetation but also an alteration of the duodenal-pancreatic interface with thickening of the duodenal wall and a common bile duct dilatation. The malignant clinical aspect and behavior of the lesion, associated to the impossibility of further investigations due to the duodenal sub stenosis, led to an exploratory laparotomy.The laparotomy revealed a retracting area straddling the duodenum and the pancreatic head. A duodenum pancreatectomy of the head of the pancreas with extended lymphadenectomy was performed and the histological evaluation showed a ductal Clear-cell adenocarcinoma of the pancreas infiltrating the duodenum. The postoperative course was characterized by a pancreatic fistula grade B. At 6 months from the surgery, the patient hasn’t had recurrence.Conclusion: Because it is a rare tumor with very few cases reported previously, the incidence and prognosis are not well known for this neoplasm. The report of our case would aid in the identification of this rare neoplasm. Further studies and more case reports are needed to clarify the diagnosis and prognostic significance of the clear cell differentiation of these tumors.
Assessing Spatial Vulnerability of Bangladesh to Climate Change and Extremes: A Geographic Information System Approach
Authors: Azam Md Golam , Rahman Md Mujibor 
Published: January 2022

Abstract
Regarding climate change, the world’s most discussed issue for the last few decades, countries like Bangladesh are always noteworthy due to its susceptibility resulting from its geography, hazard proneness, and socioeconomic condition. Thus, this aimed to justify the hypothesis that Bangladesh has spatial diversity in sectors of Climate Change Vulnerability (CCV) by identifying the sectors of vulnerability and visualizing the spatial distribution of vulnerability through multivariate geospatial analysis in the GIS environment. For an integrated assessment of CCV, 38 indicators (socio-economic and biophysical) have been incorporated in the IPCC framework in raster form. Test statistics have shown Kiser-Meyer-Olkin (KMO) value is 0.73 and the p-value of Bartlett’s sphericity is 0. The principal component analysis resulted in 6 principal components with 73.52% total explained variance. Sectors of CCV are the Climatic extreme event vulnerability (PC1), Meteorological shift vulnerability (PC2), Infrastructure and demographic vulnerability (PC3), Ecological vulnerability (PC4), Flood vulnerability (PC5), and Economic vulnerability (PC6) with Cronbach’s alpha 0.90, 0.81, 0.88, 0.72, 0.72, and 0.66 respectively. Among 3 clusters (Jenk’s Natural break) of weighted averaged indices, the highly vulnerable cluster has shown that the PC1 has the highest magnitude with a score of 0.53–0.87, while the PC5 has the highest spatial coverage with 24 districts. The present study however is a new edition in climate vulnerability assessment in Bangladesh since it encompasses multivariate spatial analysis to demonstrate countrywide CCV. This study should be an important tool for setting adaptation and mitigation strategies from the root level to policymaking platforms of Bangladesh.
ReactiveFnJ: A Choreographed Model for Fork-Join Workflow in Serverless Computing
Authors: Bharti Urmil , Goel Anita , Gupta S. C. 
Published: January 2022

Abstract
Function-as-a-Service (FaaS) is an event-based reactive programming model where functions run in ephemeral stateless containers for short duration. For building complex serverless applications, function composition is crucial to coordinate and synchronize the workflow of an application. Some serverless orchestration systems exist, but they are in their primitive state and do not provide inherent support for non-trivial workflows like, Fork-Join. To address this gap, we propose a fully serverless and scalable design model ReactiveFnJ for Fork-Join workflow. The intent of this work is to illustrate a design which is completely choreographed, reactive, asynchronous, and represents a dynamic composition model for serverless applications. Our design uses two innovative patterns, namely, Relay Composition and Master-Worker Composition to solve execution time-out challenges. As a Proof-of-Concept (PoC), the prototypical implementation of Split-Sort-Merge use case, based on Fork-Join workflow is discussed and evaluated. The ReactiveFnJ handles embarrassingly parallel computations, and its design does not depend on any external orchestration services, messaging services, and queue services. ReactiveFnJ facilitates in designing fully automated pipelines for distributed data processing systems, satisfying the Serverless Trilemma in true essence. A file of any size can be processed using our effective and extensible design without facing execution time-out challenges. The proposed model is generic and can be applied to a wide range of serverless applications that are based on the Fork-Join workflow pattern. It fosters the choreographed serverless composition for complex workflows. The proposed design model is useful for software engineers and developers in industry and commercial organizations, total solution vendors and academic researchers.
Water quality prediction based on Naïve Bayes algorithm
Authors: Ilić M. , Srdjević Z. , Srdjević B. 
Published: January 2022

Abstract
In the fast-changing world with increased water demand, water pollution, environmental problems, and related data, information on water quality and suitability for any purpose should be prompt and reliable. Traditional approaches often fail in the attempt to predict water quality classes and new ones are needed to handle a large amount or missing data to predict water quality in real time. One of such approaches is machine-learning (ML) based prediction. This paper presents the results of the application of the Naïve Bayes, a widely used ML method, in creating the prediction model. The proposed model is based on nine water quality parameters: temperature, pH value, electrical conductivity, oxygen saturation, biological oxygen demand, suspended solids, nitrogen oxides, orthophosphates, and ammonium. It is created in Netica software and tested and verified using data covering the period 2013–2019 from five locations in Vojvodina Province, Serbia. Forty-eight samples were used to train the model. Once trained, the Naïve Bayes model correctly predicted the class of water sample in 64 out of 68 cases, including cases with missing data. This recommends it as a trustful tool in the transition from traditional to digital water management.
Spatiotemporal modeling of water inrush spreading in mine roadway networks
Authors: Zhang Xiaoyan , Wu Qiang , Zhao Yingwang , Liu Shouqiang , Xu Hua 
Published: January 2022

Abstract
Water inrush accidents seriously threaten underground mining production, so the accurate prediction of the spreading process of water inrush is essential for the formulation of water-inrush-control plans and rescue schemes. This paper proposes a spatiotemporal model based on pipe-flow theory to simulate the spreading process of water inrush in mine roadway networks. The energy-loss term is added to this model to improve the simulation accuracy in bifurcated roadways, and pumps and water-blocking equipment are considered in controlling the spreading process of water inrush. Through experimental case studies, the simulation results and the function of the energy-loss term are verified. A sensitivity analysis is then carried out to assess the impact of the model parameters. The results show that the model outputs are most sensitive to the roadway length, cross-section width, and energy-loss coefficient. The model exhibited maximal sensitivity to the geometric parameters compared with the hydraulic parameters. Furthermore, the spreading process of a real water inrush in a coal mine in North China is simulated, and the water-inrush-control measures are evaluated. The overall results indicate that the proposed spatiotemporal model accurately predicts the spreading process of water inrush and is thus applicable to large-scale mine roadway networks.

Developing a Web-Based App to Assess Mental Health Difficulties in Secondary School Pupils: Qualitative User-Centered Design Study
Authors: Burn Anne-Marie , Ford Tamsin J , Stochl Jan , Jones Peter B , Perez Jesus , Anderson Joanna K 
Published: January 2022

Background
Secondary schools are an ideal setting to identify young people experiencing mental health difficulties such as anxiety or depression. However, current methods of identification rely on cumbersome paper-based assessments, which are lengthy and time-consuming to complete and resource-intensive for schools to manage. Artemis-A is a prototype web app that uses computerized adaptive testing technology to shorten the length of the assessment and provides schools with a simple and feasible solution for mental health assessment.

Objective
The objectives of this study are to coproduce the main components of the Artemis-A app with stakeholders to enhance the user interface, to carry out usability testing and finalize the interface design and functionality, and to explore the acceptability and feasibility of using Artemis-A in schools.

Methods
This study involved 2 iterative design feedback cycles—an initial stakeholder consultation to inform the app design and user testing. Using a user-centered design approach, qualitative data were collected through focus groups and interviews with secondary school pupils, parents, school staff, and mental health professionals (N=48). All transcripts were thematically analyzed.

Results
Initial stakeholder consultations provided feedback on preferences for the user interface design, school administration of the assessment, and outcome reporting. The findings informed the second iteration of the app design and development. The unmoderated usability assessment indicated that young people found the app easy to use and visually appealing. However, school staff suggested that additional features should be added to the school administration panel, which would provide them with more flexibility for data visualization. The analysis identified four themes relating to the implementation of the Artemis-A in schools, including the anticipated benefits and drawbacks of the app. Actionable suggestions for designing mental health assessment apps are also provided.

Conclusions
Artemis-A is a potentially useful tool for secondary schools to assess the mental health of their pupils that requires minimal staff input and training. Future research will evaluate the feasibility and effectiveness of Artemis-A in a range of UK secondary schools.
Piloting an Innovative Concept of e–Mental Health and mHealth Workshops With Medical Students Using a Participatory Co-design Approach and App Prototyping: Case Study
Authors: Dederichs Melina , Nitsch Felix Jan , Apolinário-Hagen Jennifer 
Published: January 2022

Background
Medical students show low levels of e–mental health literacy. Moreover, there is a high prevalence of common mental illnesses among medical students. Mobile health (mHealth) apps can be used to maintain and promote medical students’ well-being. To date, the potential of mHealth apps for promoting mental health among medical students is largely untapped because they seem to lack familiarity with mHealth. In addition, little is known about medical students’ preferences regarding mHealth apps for mental health promotion. There is a need for guidance on how to promote competence-based learning on mHealth apps in medical education.

Objective
The aim of this case study is to pilot an innovative concept for an educative workshop following a participatory co-design approach and to explore medical students’ preferences and ideas for mHealth apps through the design of a hypothetical prototype.

Methods
We conducted a face-to-face co-design workshop within an elective subject with 26 participants enrolled at a medical school in Germany on 5 consecutive days in early March 2020. The aim of the workshop was to apply the knowledge acquired from the lessons on e–mental health and mHealth app development. Activities during the workshop included group work, plenary discussions, storyboarding, developing personas (prototypical users), and designing prototypes of mHealth apps. The workshop was documented in written and digitalized form with the students’ permission.

Results
The participants’ feedback suggests that the co-design workshop was well-received. The medical students presented a variety of ideas for the design of mHealth apps. Among the common themes that all groups highlighted in their prototypes were personalization, data security, and the importance of scientific evaluation.

Conclusions
Overall, this case study indicates the feasibility and acceptance of a participatory design workshop for medical students. The students made suggestions for improvements at future workshops (eg, use of free prototype software, shift to e-learning, and more time for group work). Our results can be (and have already been) used as a starting point for future co-design workshops to promote competence-based collaborative learning on digital health topics in medical education.
