Authors: Kelem Amanuel , Shiferaw Elias , Adane Tiruneh 
Published: May 2023

Background
Metabolic Syndrome (MetS) is a cluster of interconnected metabolic diseases. Hematological abnormalities are common but neglected complications of MetS. Thus, this study aimed to determine the magnitude of hematological abnormalities and their associated factors among MetS patients at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia.

Method
A hospital-based cross-sectional study was conducted at the University of Gondar comprehensive specialized hospital from March to May 2022. A total of 384 MetS patients were selected using a systematic random sampling technique. Data were collected using pre-tested structured questionnaires and checklists. Anthropometric and blood pressure measurements were taken, and blood sample was collected for complete blood count determination. Stool and blood film examinations were performed to detect intestinal and malaria parasites, respectively. Data were entered into EpiData 3.1 and analyzed by Stata 14.0 software. Bivariate and multivariate logistic regression models were fitted to identify factors associated with hematological abnormalities. A p-value of < 0.05 was considered statistically significant.

Results
The magnitude of anemia, leukopenia, leukocytosis, thrombocytopenia, and thrombocytosis was found to be 13.3%, 0.5%, 2.9%, 1.6%, and 2.3%, respectively. Being male (AOR = 2.65, 95% CI: 1.14, 6.20), rural residency (AOR = 5.79, 95% CI: 1.72, 19.51), taking antihypertensive medications (AOR = 3.85, 95% CI: 1.16, 12.78), having elevated triglyceride level (AOR = 2.21, 95% CI: 1.03, 4.75), and being overweight or obese (AOR = 0.32, 95% CI: 0.16, 0.64) were significantly associated with anemia.

Conclusions
Anemia was the most prevalent hematological abnormality identified in the present study, followed by leukocytosis and thrombocytosis. Anemia was a mild public health problem among MetS patients in the study area. Routine anemia screening for all MetS patients, especially for those with significant associated factors, may help in the early detection and effective management of anemia, which subsequently improves the patients’ quality of life.

Published: May 2023

BackgroundSociodemographic disparities in atrial fibrillation (AF) management and thromboembolic prophylaxis have previously been reported, which may involve inequitable access to left atrial appendage occlusion (LAAO) during cardiac surgery. The present study aimed to evaluate the association of LAAO utilization with sex, race, and hospital region among patients with AF undergoing heart valve operations.MethodsAdults with AF undergoing valve replacement/repair in the 2012–2019 National Inpatient Sample were identified and stratified based on concurrent LAAO. Multivariable linear and logistic regressions were developed to identify factors associated with LAAO utilization. Mortality, complications including stroke and thromboembolism, hospitalization costs and length of stay (LOS) were secondarily assessed.ResultsOf 382,580 patients undergoing valve operations, 18.7% underwent concomitant LAAO. Over the study period, the proportion of female patients receiving LAAO significantly decreased from 44.8% to 38.9% (p<0.001). Upon risk adjustment, female (AOR 0.93 [95% CI 0.89–0.97]) and Black patients (0.91 [0.83–0.99]) had significantly reduced odds of undergoing LAAO compared to males and Whites, respectively. Additionally, hospitals in the Midwest (1.38 [1.24–1.51]) and West (1.26 [1.15–1.36]) had increased likelihood of LAAO whereas Northeast hospitals (0.85 [0.77–0.94)] had decreased odds relative to the South. Furthermore, LAAO was associated with decreased stroke (0.71 [0.60–0.84]) and thromboembolism (0.68 [0.54–0.86]), $4,200 reduction in costs and 1-day decrement in LOS.ConclusionsFemale and Black patients had significantly lower odds while Midwest and Western hospitals had greater odds of LAAO utilization. Enhancing access to LAAO during valvular surgery is warranted to improve clinical and financial outcomes for patients with AF.
Occupational radiation exposure dose and associated factors among radiology personnel in Eastern Amhara, Ethiopia
Authors: Alemayehu Tadesse Guangul , Bogale Getahun Gebre , Bazie Getaw Walle 
Published: May 2023

Background
Ionizing radiation is being used more frequently in medicine, which has been linked to recognized biological effects such as cancer and mortality. Radiology services are becoming more widely available in Ethiopian health facilities but there is no compiled record of worker’s radiation dose. So, assessing the magnitude and identifying the associated factors of occupational radiation exposure dose among radiology personnel help to design strategies for radiation protection.

Objective
The study was designed to assess the occupational radiation exposure dose and associated factors among radiology personnel in eastern Amhara, northeast Ethiopia, 2021.

Methods
Cross-sectional study was conducted from March 25 to April 30, 2021, in 57 health institutions among 198 radiology personnel. The study comprised all eligible radiology personnel. The data were collected using an electronic-based (Google form) self-administered questionnaire, and document review. The data were entered into an excel spread sheet and then, exported to Stata 14 software. Linear regression model was used to analyse the data after checking its assumptions. Variables with a p-value < 0.25 were entered into a multiple linear regression analysis, and those with a p-value < 0.05 were judged significant. VIF was used to check for multi-collinearity. Coefficient of determination was used to check the model fitness.

Results
The mean (± SD) annual shallow and deep dose equivalents of radiology personnel were 1.20 (± 0.75) and 1.02 (± 0.70) mSv, respectively. Body mass index (β = 0.104, 95% CI: 0.07, 0.14), practice of timing (β = -0.43, 95% CI: -0.73, -0.13), working experience (β = -0.04, 95% CI: -0.048, -0.032), and practice of distancing (β = -0.26, 95% CI: -0.49, -0.17) were found to be statistically significant factors of annual deep dose equivalent. In addition, body mass index (β = 0.113, 95% CI: 0.08, 0.15), practice of timing (β = -0.62 95% CI: -0.93, -0.31) and, working experience (β = -0.044, 95% CI: -0.053, -0.036 had statistically significant associations with annual shallow dose equivalent.

Conclusion
The annual dose equivalents were two times higher than the global average of annual per caput effective dose due to medical exposure. Body mass index, practice of timing, working experience, and practice of distancing were factors of occupational radiation exposure dose. Strategies focusing on increasing the skill, experience, and lifestyle of radiology personnel would be supreme important means to reduce occupational radiation exposure dose.
Calcium‐ and voltage‐driven atrial alternans: Insight from [Ca]i and Vm asynchrony
Authors: Kanaporis G. , Martinez‐Hernandez E. , Blatter L. A. 
Published: May 2023

AbstractCardiac alternans is defined as beat‐to‐beat alternations in contraction strength, action potential duration (APD), and Ca transient (CaT) amplitude. Cardiac excitation–contraction coupling relies on the activity of two bidirectionally coupled excitable systems, membrane voltage (Vm) and Ca release. Alternans has been classified as Vm‐ or Ca‐driven, depending whether a disturbance of Vm or [Ca]i regulation drives the alternans. We determined the primary driver of pacing induced alternans in rabbit atrial myocytes, using combined patch clamp and fluorescence [Ca]i and Vm measurements. APD and CaT alternans are typically synchronized; however, uncoupling between APD and CaT regulation can lead to CaT alternans in the absence of APD alternans, and APD alternans can fail to precipitate CaT alternans, suggesting a considerable degree of independence of CaT and APD alternans. Using alternans AP voltage clamp protocols with extra APs showed that most frequently the pre‐existing CaT alternans pattern prevailed after the extra‐beat, indicating that alternans is Ca‐driven. In electrically coupled cell pairs, dyssynchrony of APD and CaT alternans points to autonomous regulation of CaT alternans. Thus, with three novel experimental protocols, we collected evidence for Ca‐driven alternans; however, the intimately intertwined regulation of Vm and [Ca]i precludes entirely independent development of CaT and APD alternans.
Interactional features in second language classroom discourse: variations across novice and experienced language teachers

Published: May 2023

Abstract
Classrooms provide a context in which teachers and learners co-construct meaning in light of their sociocultural understandings and profiles. However, to date, few studies have scrutinized the way such profiles contribute to teachers’ classroom discourse. Informed by the methodological framework of conversation analysis and drawing upon a corpus of 20-h naturally-occurring classroom interactions, the present study examined variations in novice and experienced teachers’ classroom discourse in providing opportunities for learner interlanguage development. The study relied on Walsh’s (2006. Investigating classroom discourse. Routledge) conceptualization of classroom context mode in the data collection and analysis stages. Quantitative and qualitative analyses of the data revealed that the experienced teachers’ discourse was marked by greater simultaneity and immediacy characteristics targeted at learner engagement in comparison to novice teachers. The study findings highlight variations between the two groups across a range of discursive constructions and provide implications for enhancing novice teachers’ classroom discourse.
Dutch Loanwords in Russian: A Cultural-Historical Perspective
Authors: Ai Xin 
Published: May 2023

Abstract
Compared with other loanwords in Russian, the borrowing of Dutch vocabulary has a clear historical and cultural motivation and is closely related to the reforms and westernization during the reign of Peter I (1682–1725) in the late 17th and the early 18th centuries. Dutch loanwords in Russian are mainly distributed in the fields of navigation and construction technology, with some nouns of new objects introduced through business transactions, many of which have become active vocabulary commonly used in modern Russian. Trying to break away from the barriers of traditional linguistic research, this article will analyze the motives, semantic fields, phonetic and grammatical characteristics of Dutch loanwords from the perspective of cultural history to explore and confirm the approaches and characteristics of cultural and technological exchanges between Russia and the Netherlands during the reforms of Peter I, as well as their presence in vocabulary.
SMACS: A framework for formal verification of complex adaptive systems
Authors: Fakhir Ilyas , Kazmi Asad Raza , Qasim Awais , Ishaq Atif 
Published: May 2023

Abstract
Self-adaptive systems (SASs) have the capability to evaluate and change their behavior according to changes occurring in the environment. Research in this field is being held since mid-60, and over the last decade, the importance of self-adaptivity is being increased. In the proposed research, colored petri nets (CPN) formal language is being used to model self-adaptive multiagent system. CPN is increasingly used to model self-adaptive complex concurrent systems due to its flexible formal specification and formal verification behavior. CPN being visually more expressive than simple, Petri Nets enable diverse modeling approaches and provides a richer framework for such a complex formalism. The main goal of this research is to apply self-adaptive multi-agent concurrent system (SMACS) for complex architectures. In our previous research, the SMACS framework is proposed and verified through traffic monitoring system. All agents of SMACS are also known as intelligent agents due to their self-adaptation behavior. Due to decentralized approach in this framework, each agent will intelligently adapt its behavior in the environment and send updates to other agents. In this research, we are choosing smart computer lab (SCL) as a case study. For internal structure of each agent modal,

-calculus will be used, and then a model checker TAPAs: a tool for the analysis of process algebras will be applied to verify these properties. CPN-based state space analysis will also be done to verify the behavioral properties of the model. The general objective of the proposed system is to maximize the utility generated over some predetermined time horizon.

, particularly for quadratic systems. Even with the hundreds of studies on the topology of real planar quadratic vector fields, fully characterizing their phase portraits is still a difficult problem. This paper is devoted to classifying the phase portraits of two polynomial vector fields with two usual invariant algebraic curves, by investigating the geometric solutions within the Poincaré disc. One can notice that these systems yield 26 topologically different phase portraits.

Abstract
The aim of this study was to conduct a comprehensive literature review of the dimensions of open science in research processes. A total of four databases and snowball searching were used for the comprehensive literature review during 2011–2020; then, we were able to find 98 studies based on the inclusion criteria. Also, we used thematic method to review the relevant studies and identified three categories of dimensions in the research process, namely (1) the publication and sharing category including open access, open data, transparency and reproducibility, citizen science, and crowd sourcing; (2) the infrastructure and cultural category including open infrastructure, open education, open tools, budget mechanism, open culture, and communication; and (3) governance and evaluation including policies, governance, and the ethical principles associated with open science. Open science emphasizes the efforts to open and make the scientific research process more inclusive so as to engage the inside and outside actors in the research process.
Total variation bound for Milstein scheme without iterated integrals
Authors: Yamada Toshihiro 
Published: May 2023

AbstractThe paper gives new results for the Milstein scheme of stochastic differential equations. We show that (i) the Milstein scheme holds as a weak approximation in total variation sense and is given by second-order polynomials of Brownian motion without using iterated integrals under non-commutative vector fields; (ii) the accuracy of the Milstein scheme is better than that of the Euler–Maruyama scheme in an asymptotic sense. In particular, we provedTV⁢(XTε,X¯Tε,Mil,(n))≤C⁢ε2/nd_{\mathrm{TV}}(X_{T}^{\varepsilon},\bar{X}_{T}^{\varepsilon,\mathrm{Mil},(n)})\leq C\varepsilon^{2}/nanddTV⁢(XTε,X¯Tε,EM,(n))≤C⁢ε/nd_{\mathrm{TV}}(X_{T}^{\varepsilon},\bar{X}_{T}^{\varepsilon,\mathrm{EM},(n)})\leq C\varepsilon/n, wheredTVd_{\mathrm{TV}}is the total variation distance,XεX^{\varepsilon}is a solution of a stochastic differential equation with a small parameter 𝜀, andX¯ε,Mil,(n)\bar{X}^{\varepsilon,\mathrm{Mil},(n)}andX¯ε,EM,(n)\bar{X}^{\varepsilon,\mathrm{EM},(n)}are the Milstein scheme without iterated integrals and the Euler–Maruyama scheme, respectively. In computational aspect, the scheme is useful to estimate probability distribution functions by a simple simulation without Lévy area computation. Numerical examples demonstrate the validity of the method.

Authors: Zeng Junan , Zhao Guangyu 
Published: May 2023

Abstract
Sepsis is one of the most fatal inflammatory diseases with multiple organ failure caused by pathological infection. α-Hederin, a monodesmosidic triterpenoid saponin, has many biological activities including anti-inflammation. This study aimed to investigate the effect of α-Hederin on lung and liver injuries in septic mice. Mice underwent cecal ligation and puncture-induced sepsis were intraperitoneally injected with 0.3 or 3 mg/kg α-Hederin. α-Hederin treatment dose-dependently attenuated the lung and liver injuries in septic mice. Correspondingly, α-Hederin significantly decreased malondialdehyde production, increased the levels of superoxide dismutase and glutathione in lung tissues, reduced serum alanine aminotransferase and aspartate aminotransferase activities, and suppressed the levels of TNF-α and IL-6 in both tissues and in the serum. Moreover, α-Hederin augmented CD206 level and inhibited the productions of CD86 and iNOS in lung and liver tissues of septic mice. Importantly, p-p65/p65 was suppressed, whereas IκB was elevated by α-Hederin. In conclusion, α-Hederin could improve the lung and liver injuries in mice with sepsis by regulating macrophage M1/M2 polarization and inhibiting the activation of NF-κB signaling pathway.

Abstract
Paper has been used in the field of hygiene for centuries. Tissue papers have low grammage, creped or non-creped surface, and consisting of one or more layers from virgin papers. Toilet paper, which has an important area of use, comes at the beginning of the tissue papers divided into various product groups. Its use has increased even more with the effect of the coronavirus pandemic. Increasing use of toilet paper causes clogging in sewers as solid waste. Because an important and large part of the sewage is composed of cellulosic structures. Therefore, the disintegration of toilet paper is an important issue. The main properties of toilet paper are characterized by grammage, thickness, polymerization degree, softness and wet tensile strength. This study, it was aimed to determine the relationship between the degree of polymerization, thickness, grammage, softness and wet tension strength of toilet papers, which accumulate in the sewer pipes and cause clogging, and their disintegration in tap water and pure water at environment of different pH levels. A great level and positive linear relationship was found between grammage and in disintegration pH9. It was determined a low level and positive relationship with wet tensile strength in disintegration tap water.
Mechanical equipment fault diagnosis based on wireless sensor network data fusion technology
Authors: Hao Fang , Yang Qiuping , Sharma Anjali , Balyan Vipin 
Published: May 2023

Abstract
To save network energy consumption and prolong network life cycle in complex mechanical fault diagnosis, a research method of data fusion routing protocol algorithm based on wireless sensor network (WSN) is proposed. The specific content of the method is as follows: First, the low-energy adaptive clustering hierarchy algorithm is analyzed and discussed. On this basis, the prim route fusion algorithm is proposed to realize the effective utilization of energy and prolong the life of the network. Then, the WSN is abstracted as an undirected graph. From the perspective of saving the energy of the whole network, several current algorithms for building fusion trees are compared. The experimental results show that the prim algorithm consumes energy only after 700 rounds of clustering, while the leach clustering algorithm consumes energy only after 500 rounds. This shows that applying the prim algorithm can reduce the energy consumption of the whole network and prolong the life cycle of the network. However, the algorithm is carried out on the premise of uniform distribution of nodes, and there is a certain gap with the specific application of WSN in mechanical fault diagnosis. In the comparison of node energy consumption, it is found that compared with using the shortest path tree, using the central point of graph algorithm can greatly save the energy consumption of the node and has better performance. Practice has proved that this method can effectively remove redundant data information and solve the problem of unreliable data collected by a single sensor node. It is more suitable for the specific application of WSN in mechanical fault diagnosis.

Effects of plaque shape on arterial blood flow
Authors: Marušić Karla , Marušić-Paloka Eduard , Vrdoljak Marko 
Published: May 2023

Abstract
Plaque reduces the conductivity of the blood vessel and its shape is more important than its quantity. We show that, for given quantity, the conductivity is maximal if the plaque forms a uniform layer next to the vessel wall and leaves a circular hole in the middle. On the other hand, for any quantity of the plaque a shape can be found such that the conductivity of the vessel is arbitrary close to zero.
