BackgroundNumerous wearables are used in a research context to record cardiac activity although their validity and usability has not been fully investigated. The objectives of this study is the cross-model comparison of data quality at different realistic use cases (cognitive and physical tasks). The recording quality is expressed by the ability to accurately detect the QRS complex, the amount of noise in the data, and the quality of RR intervals.MethodsFive ECG devices (eMotion Faros 360°, Hexoskin Hx1, NeXus-10 MKII, Polar RS800 Multi and SOMNOtouch NIBP) were attached and simultaneously tested in 13 participants. Used test conditions included: measurements during rest, treadmill walking/running, and a cognitive 2-back task. Signal quality was assessed by a new local morphological quality parameter morphSQ which is defined as a weighted peak noise-to-signal ratio on percentage scale. The QRS detection performance was evaluated with eplimited on synchronized data by comparison to ground truth annotations. A modification of the Smith-Waterman algorithm has been used to assess the RR interval quality and to classify incorrect beat annotations. Evaluation metrics includes the positive predictive value, false negative rates, and F1 scores for beat detection performance.ResultsAll used devices achieved sufficient signal quality in non-movement conditions. Over all experimental phases, insufficient quality expressed by morphSQ values below 10% was only found in 1.22% of the recorded beats using eMotion Faros 360°whereas the rate was 8.67% with Hexoskin Hx1. Nevertheless, QRS detection performed well across all used devices with positive predictive values between 0.985 and 1.000. False negative rates are ranging between 0.003 and 0.017. eMotion Faros 360°achieved the most stable results among the tested devices with only 5 false positive and 19 misplaced beats across all recordings identified by the Smith-Waterman approach.ConclusionData quality was assessed by two new approaches: analyzing the noise-to-signal ratio using morphSQ, and RR interval quality using Smith-Waterman. Both methods deliver comparable results. However the Smith-Waterman approach allows the direct comparison of RR intervals without the need for signal synchronization whereas morphSQ can be computed locally.

Purpose
Life satisfaction influences well-being. Medical students often experience more stress as compared to their counterparts in other disciplines as they are required to meet the demands of both academic workload and clinical responsibilities. However, during the current pandemic, in addition to academic changes, inability to complete clinical placements, loss of peer interaction and social connectedness and, deployment to areas in times of crisis could exacerbate their stress. This would impact their ability to cope with stress and eventually influence their life satisfaction. Students approach these challenges in various ways, either positively, religiously, or by avoiding. This study aimed to explore the association between resilience, coping mechanisms and life satisfaction in medical students during the pandemic.

Methods
A cross-sectional web-based survey was conducted from undergraduate medical students from year 1 to year 5. Three instruments were used to measure life satisfaction, resilience, and coping, namely The Brief Resilience Scale, The Satisfaction with Life Scale and the COPE inventory. Mean and standard deviation were calculated for all continuous variables. Robust linear regression model was used for analysis. Hierarchical (forward) stepwise model building technique was used for final model. Alpha cut off was kept at 0.05.

Results
A total of 351 students (out of 500 students) completed the questionnaires. A moderately negative, slightly linear correlation between life satisfaction and avoidant coping was reported. Life satisfaction showed moderately positive, slightly linear correlation with resilience score. Three variables stayed significant in the final model: Resilience, avoidant coping, and religion coping.

Conclusion
Life satisfaction can be improved among medical students by focusing on strategies which enhance resilience. Religion is identified as a significant coping strategy among medical students. Students coping mechanism can vary and more research is needed to assess which types of coping strategies could contribute positively to the quality of their personal and professional lives

BackgroundWeight loss, hyperglycaemia and diabetes are known features of pancreatic cancer. We quantified the timing and the amount of changes in body mass index (BMI) and glycated haemoglobin (HbA1c), and their association with pancreatic cancer from five years before diagnosis.MethodsA matched case-control study was undertaken within 590 primary care practices in England, United Kingdom. 8,777 patients diagnosed with pancreatic cancer (cases) between 1stJanuary 2007 and 31stAugust 2020 were matched to 34,979 controls by age, gender and diabetes. Longitudinal trends in BMI and HbA1c were visualised. Odds ratios adjusted for demographic and lifestyle factors (aOR) and 95% confidence intervals (CI) were calculated with conditional logistic regression. Subgroup analyses were undertaken according to the diabetes status.ResultsChanges in BMI and HbA1c observed for cases on longitudinal plots started one and two years (respectively) before diagnosis. In the year before diagnosis, a 1 kg/m2decrease in BMI between cases and controls was associated with aOR for pancreatic cancer of 1.05 (95% CI 1.05 to 1.06), and a 1 mmol/mol increase in HbA1c was associated with aOR of 1.06 (1.06 to 1.07). ORs remained statistically significant (p< 0.001) for 2 years before pancreatic cancer diagnosis for BMI and 3 years for HbA1c. Subgroup analysis revealed that the decrease in BMI was associated with a higher pancreatic cancer risk for people with diabetes than for people without (aORs 1.08, 1.06 to 1.09 versus 1.04, 1.03 to 1.05), but the increase in HbA1c was associated with a higher risk for people without diabetes than for people with diabetes (aORs 1.09, 1.07 to 1.11 versus 1.04, 1.03 to 1.04).ConclusionsThe statistically significant changes in weight and glycaemic control started three years before pancreatic cancer diagnosis but varied according to the diabetes status. The information from this study could be used to detect pancreatic cancer earlier than is currently achieved. However, regular BMI and HbA1c measurements are required to facilitate future research and implementation in clinical practice.

Higher education goes beyond the development of technical skills, and plays a central role in the social transformation of the environment in which it is inserted. This role is fostered within institutions through research, teaching and extension. This work is a report of the experience of students of the APAE of São Pedro, within the extension project "APAE no Senac", carried out by the Centro Universitário Senac, Águas de São Pedro campus (SP). Its purpose was to promote the social inclusion of these people, given that one of the main functions of gastronomy, since the discovery of fire, has been to bring people together. The APAE students were able to gain experience of activities of the degree in gastronomy technology by applying cooking and recipe replication techniques, in a controlled environment, in twelve demonstrative and practical classes, accompanied by project scholarship students and advisory professors from the HEI. The classes were developed in the kitchens and restaurant laboratories of the college. It was observed that there is potential for replicability of the work model, due to its characteristics and the low investment required. There is also potential to generate the teaching experience for HEI students and social inclusion for APAE students, through the mastery of new tools and techniques in the area of gastronomy.

This article examines themes of collaboration and stewardship, the importance of cultural protocols, and the intergenerational transmission of knowledge in the context of a Haida totem pole raising ceremony held at the Denver Art Museum in November 2019. Collaborating with members of the Wallace family, direct descendants of the original owners of the house frontal and memorial poles in its collection, the Denver Art Museum organized the event to honor the family’s legacy and the history of the poles. In this article, we outline the planning process, events, and outcomes of the event, and situate this within the context of Haida cultural practices. Combined with an analysis of Haida oratory, song, and dance, we demonstrate the ways in which collaborations that honor Haida cultural protocols can engender meaningful relationships between institutions and originating communities.

Published: October 2022

The goal of this research is to look into Langkawi's desirability as a potential senior-friendly destination in Malaysia through the eyes of a middle-aged tourist. The four attractiveness dimensions of a prospective senior-friendly location developed in the research framework are attractions, accessibility, amenities, and complementary services. Malaysians aged 40 to 54 make up the study's sample population. The descriptive analysis is used in the study to expand on the data and interpret it into findings. One hundred twenty-six respondents found that attractions are the most impactful feature of a senior-friendly destination. Various cultural and historical monuments, such as Makam Mahsuri and Padang Mat Sirat, influenced middle-aged travellers' preferences and choices. The result also highlights four attractive factors that players in the Langkawi tourism industry can employ to increase tourist satisfaction and obtain a competitive advantage over other tourism locations. Stakeholders should work to improve the destination's attractiveness to fulfil the needs of senior tourists and make it a future senior-friendly attraction by 2050. The study results provide an opportunity for theoretical expansion in the highlighted academic and practical implications.

Abstract
In this paper, we investigate the buckling problem of the drifting Laplacian of arbitrary order on a bounded connected domain in complete smooth metric measure spaces (SMMSs) supporting a special function, and successfully obtain a general inequality for its eigenvalues. By applying this general inequality, if the complete SMMSs considered satisfy some curvature constraints, we can obtain a universal inequalities for eigenvalues of this buckling problem.

Published: October 2022

Abstract
Research shows that Attention Deficit Hyperactivity Disorder (ADHD) is related to a disorder in brain networks. The purpose of this study is to use an effective connectivity measure and graph theory to examine the impairments of brain connectivity in ADHD. Weighted directed graphs based on electroencephalography (EEG) signals of 61 children with ADHD and 60 healthy children were constructed. The edges between two nodes (electrodes) were calculated by Phase Transfer Entropy (PTE). PTE is calculated for five frequency bands: delta, theta, alpha, beta, and gamma. The graph theory measures were divided into two categories: global and local. Statistical analysis with global measures indicates that in children with ADHD, the segregation of brain connectivity increases while the integration of the brain connectivity decreases compared to healthy children. These brain network differences were identified in the delta and theta frequency bands. The classification accuracy of 89.4% is obtained for both in-degree and strength measures in the theta band. Our result indicated local graph measures classified ADHD and healthy subjects with accuracy of 91.2 and 90% in theta and delta bands, respectively. Our analysis may provide a new understanding of the differences in the EEG brain network of children with ADHD and healthy children.

Authors: Palanivel Silambarasi , Nallasamy Viswanathan 
Published: October 2022

Abstract

Objectives
The leukocyte is a specialized immune cell that functions as the foundation of the immune system and keeps the body healthy. The WBC classification plays a vital role in diagnosing various disorders in the medical area, including infectious diseases, immune deficiencies, leukemia, and COVID-19. A few decades ago, Machine Learning algorithms classified WBC types required for image segmentation, and the feature extraction stages, but this new approach becomes automatic while existing models can be fine-tuned for specific classifications.

Methods
The inception architecture and deep learning model-based Resnet connection are integrated into this article. Our proposed method, inception Resnet-v3, was used to classify WBCs into five categories using 15.7k images. Pathologists made diagnoses of all images so a model could be trained to classify five distinct types of cells.

Results
After implementing the proposed architecture on a large dataset of 5 categories of human peripheral white blood cells, it achieved high accuracy than VGG, U-Net and Resnet. We tested our model with WBC images from additional public datasets such as the Kaagel data sets and Raabin data sets of which the accuracy was 98.80% and 98.95%.

Conclusions
Considering the large sample sizes, we believe the proposed method can be used for improving the diagnostic performance of clinical blood examinations as well as a promising alternative for machine learning. Test results obtained with the system have been satisfying, with outstanding values for Accuracy, Precision, Recall, Specificity and F1 Score.

Published: October 2022

Abstract
Through the analysis of the current research situation at home and abroad, this article finds that there is a lack of evaluation standards and methods in the virtual simulation experiment of e-commerce logistics smart warehousing. Therefore, it seriously affects the standardization and rationality of the experiment. To solve the problems in the evaluation of the current virtual simulation experiment, this article proposes a virtual simulation experiment evaluation model of e-commerce logistics smart warehousing based on multidimensional weighting. This article firstly sorts out the basic process of e-commerce logistics smart warehousing experiment activities and establishes the evaluation object. Then, based on the duality degree of the output results of the experimental steps, it proposes a method that conforms to the corresponding operation steps. Thus, a three-dimensional evaluation model of the completion degree of the operation steps, the reasonable degree of the operation steps, and the completion time of the operation steps are constructed. An automatic scoring evaluation model is proposed based on the combination of three-dimensional weighted evaluation of experimental steps. Finally, the feasibility and convenience of the evaluation model are verified through the experiment analysis.

Abstract
In this article, motivated by the works of Ali Akbar and Elahe Shahrosvand [Split equality common null point problem for Bregman quasi-nonexpansive mappings, Filomat 32 (2018), no. 11, 3917–3932], Eskandani et al. [A hybrid extragradient method for solving pseudomonotone equilibrium problem using Bregman distance, J. Fixed Point Theory Appl. 20 (2018), 132], B. Ali and M. H. Harbau [Convergence theorems for Bregman K-mappings and mixed equilibrium problems in reflexive Banach spaces, J. Funct. Spaces (2016) Article ID 5161682, 18 pages], and some other related results in the literature, we introduce a hybrid extragradient iterative algorithm that employs a Bregman distance approach for approximating a split feasibility problem for a finite family of equilibrium problems involving pseudomonotone bifunctions and fixed point problems for a finite family of Bregman quasi-asymptotically nonexpansive mappings using the concept of Bregman K-mapping in reflexive Banach spaces. Using our iterative algorithm, we state and prove a strong convergence result for approximating a common solution to the aforementioned problems. Furthermore, we give an application of our main result to variational inequalities and also report a numerical example to illustrate the convergence of our method. The result presented in this article extends and complements many related results in the literature.
Bi-absolutive constructions in Chechen
Authors: Molochieva Zarina , Faghiri Pegah , van Lier Eva 
Published: October 2022

AbstractThis study presents new data on the bi-absolutive construction in Chechen, a Nakh-Daghestanian language spoken in the northern Caucasus. The basic case frame in a transitive clause in Chechen is ergative-absolutive. In progressive constructions with an auxiliary and a simultaneous converb, the basic case frame alternates with an absolutive-absolutive – or bi-absolutive – construction. To assess the factors conditioning this alternation, we use data from two corpora (one of spoken narratives and one of written newspaper articles) and data elicited from native speakers using visual (video and picture) stimuli. We discuss conditions on the relatively infrequent bi-absolutive construction in terms of (in)animacy/humanness of the A argument, verb class, discourse-based factors, and aspectual meaning. We connect our results to existing studies of bi-absolutive constructions in other Nakh-Daghestanian languages as well as to methodological challenges associated with the study of minority patterns in under-resourced languages.
Reversible ring property via idempotent elements
Authors: Kose Handan , Ungor Burcu , Harmanci Abdullah 
Published: October 2022

Abstract
Regarding the question of how idempotent elements affect the reversible property of rings, we study a version of reversibility depending on idempotents.
In this perspective, we introduce right (resp., left) 𝑒-reversible rings.
We show that this concept is not left-right symmetric.
Basic properties of right 𝑒-reversibility in a ring are provided.
Among others, it is proved that if 𝑅 is a semiprime ring, then 𝑅 is right 𝑒-reversible if and only if it is right 𝑒-reduced if and only if it is 𝑒-symmetric if and only if it is right 𝑒-semicommutative.
Also, for a right 𝑒-reversible ring 𝑅, 𝑅 is a prime ring if and only if it is a domain.
It is shown that the class of right 𝑒-reversible rings lies strictly between that of 𝑒-symmetric rings and right 𝑒-semicommutative rings.
Some extensions of rings are studied in terms of 𝑒-reversibility.
Characteristics of internal flow of nozzle integrated with aircraft under transonic flow
Authors: Li Zijie , Wang Hao 
Published: October 2022

Abstract
To reveal how aircraft affects the internal flow of the ejector nozzle, we have constructed three model types in this article. These include the model of SR-71 aircraft, the model that only contains ejector nozzle with third auxiliary valve, and the model that integrates the previous two. The results showed that in the transonic regime (M
a = 1.2), the third auxiliary flow mainly stems from the boundary layer of the aircraft body. Indeed, a large-scale flow separation phenomenon near the third auxiliary door may require a more nuanced description. The mainstream flow is always in an overexpansion state and results in a Mach plate structure at the exit of the nozzle. However, after integration, the rates of the third auxiliary and the secondary flow are reduced by 18.15% and 5.26%, respectively. Meanwhile, the mainstream flow demonstrates higher overexpansion levels, the position of the Mach plate further downstream changes, and the thrust coefficient decreases by 1.75%. It is worthwhile noting that a strong pressure gradient occurs in the circumferential direction near the connecting structure, which induces lateral flow. This lateral flow breaks away from the wall under the reverse pressure gradient of the nozzle, thus forming three vortex pairs.
