BackgroundThe public health response to the global COVID-19 pandemic has varied widely by region. In Africa, uptake of effective COVID-19 vaccines has been limited by accessibility and vaccine hesitancy. The aim of this study was to compare perceptions of COVID-19 infection and vaccination between pregnant women and non-pregnant adults in four regions of Cameroon, located in Central Africa.MethodsA cross-sectional survey study was conducted at urban and suburban hospital facilities in Cameroon. Participants were randomly selected from a convenience sample of adult pregnant and non-pregnant adults in outpatient clinical settings between June 1stand July 14th, 2021. A confidential survey was administered in person by trained research nurses after obtaining written informed consent. Participants were asked about self-reported sociodemographics, medical comorbidities, perceptions of COVID-19 infection, and vaccination. Descriptive statistics were used for survey responses and univariate and multivariable logistic regression models were created to explore factors associated with COVID-19 vaccine acceptability.ResultsFewer than one-third of participants were interested in receiving the COVID-19 vaccine (31%, 257/835) and rates did not differ by pregnancy status. Overall, 43% of participants doubted vaccine efficacy, and 85% stated that the vaccine available in Africa was less effective than vaccine available in Europe. Factors independently associated with vaccine acceptability included having children (aOR = 1.5; p = 0.04) and higher education (aOR = 1.6 for secondary school vs primary/none; p = 0.03). Perceived risks of vaccination ranged from death (33%) to fetal harm (31%) to genetic changes (1%). Health care professionals were cited as the most trusted source for health information (82%, n = 681).ConclusionCOVID-19 vaccine hesitancy and misinformation in Cameroon was highly prevalent among pregnant and non-pregnant adults in 2021 while vaccine was available but not recommended for use in pregnancy. Based on study findings, consistent public health messaging from medical professionals about vaccine safety and efficacy and local production of vaccine are likely to improve acceptability.

BackgroundSince the onset of the COVID-19 pandemic, children have been mentally and physically burdened, particularly due to school closures, with an associated loss of learning. Therefore, efficient testing strategies with high sensitivity are necessary to keep schools open. Apart from individual rapid antigen testing, various methods have been investigated, such as PCR-based pool-testing of nasopharyngeal swabs, gargle, or saliva samples. To date, previous validation studies have found the PCR-based saliva swab pool testing method to be an effective screening method, however, the acceptability and feasibility of a widespread implementation in the school-setting among stakeholders has not been comprehensively evaluated.MethodsIn this pilot study, SARS-CoV-2 saliva swab pool testing of up to 15 swabs per pool was conducted in ten primary and special schools in Mecklenburg-Western Pomerania, Germany, over a period of one month. Thereafter, parents, teachers and school principals of the participating schools as well as the participating laboratories were surveyed about the feasibility and acceptability of this method, its large-scale implementation and challenges. Data were analyzed quantitatively and qualitatively.ResultsDuring the study period, 1,630 saliva swab pools were analyzed, of which 22 tested SARS-CoV-2 positive (1.3%). A total ofN= 315 participants took part in the survey. Across all groups, the saliva swab pool testing method was perceived as more child-friendly (>87%), convenient (>82%), and easier (>81%) compared to rapid antigen testing by an anterior nasal swab. Over 80% of all participants favored widespread, regular use of the saliva swab method.ConclusionIn school settings in particular, a high acceptability of the test method is crucial for a successful SARS-CoV-2 surveillance strategy. All respondents clearly preferred the saliva swab method, which can be used safely without complications in children six years of age and older. Hurdles and suggestions for improvement of an area-wide implementation were outlined.
An overset mesh approach for a vibrating cylinder in uniform flow
Authors: Hamdoon Farouk Omar , Jaber Alaa Abdulhady , Flaieh Enass H. 
Published: September 2022

Abstract
This paper has numerically investigated twodimensional laminar flow over a vibrating circular cylinder. Numerical simulation is performed using the dynamic overset mesh method available in commercial software ANSYS FLUENT 19.0. A simple harmonic motion is applied to simulate the cylinder vibration using the user-defined function (UDF) tool in FLUENT. To examine the accuracy and the capability of the present overset mesh approach, two test types of cylinder vibration are simulated: crossflow and inline vibrations. All simulations are performed at a constant Reynolds number (Re = 100) to predict the occurrence of synchronization or lock-in phenomenon. For the case of crossflow vibration, it is observed that lock-in occurs with cylinder oscillation frequency near the Strouhal frequency of the fixed cylinder. However, for the inline vibration, lockin occurs near twice the Strouhal frequency of the fixed cylinder. Furthermore, in the case of crossflow oscillation, the frequency content in the lift coefficients’ time history is successfully linked to the phase portraits’ shape and the vorticity field. The simulation results are consistent with the available published data in the literature. This indicates that the present numerical technique is valid and capable of modeling flows with moving structural systems.

Published: September 2022

Abstract
The exact traveling wave solutions of generalized Davey-Stewartson equations with arbitrary power nonlinearities are studied using the dynamical system and the first integral methods. Taking different parameter conditions, we obtain periodic wave solutions, exact solitary wave solutions, kink wave solutions, and anti-kink wave solutions.
Hopf bifurcation and Turing instability in a diffusive predator-prey model with hunting cooperation
Authors: Miao Liangying , He Zhiqian 
Published: September 2022

Abstract
In this article, we study Hopf bifurcation and Turing instability of a diffusive predator-prey model with hunting cooperation. For the local model, we analyze the stability of the equilibrium and derive conditions for determining the direction of Hopf bifurcation and the stability of the bifurcating periodic solution by the center manifold and the normal form theory. For the reaction-diffusion model, first it is shown that Turing instability occurs, then the direction and stability of the Hopf bifurcation is reached. Our results show that hunting cooperation plays a crucial role in the dynamics of the model, that is, it can be beneficial to the predator population and induce the rise of Turing instability. Finally, numerical simulations are performed to visualize the complex dynamic behavior.
Fibroblast growth factor 21 and dietary interventions: what we know and what we need to know next
Authors: Jin Tianru 
Published: September 2022

Abstract
Dietary interventions include the change of dietary styles, such as fasting and dietary or nutrient restrictions; or the addition of plant-derived compounds (such as polyphenols known as curcumin, resveratrol, or anthocyanin, or other nutraceuticals) into the diet. During the past a few decades, large number of studies have demonstrated therapeutic activities of these dietary interventions on metabolic and other diseases in human subjects or various animal models. Mechanisms underlying those versatile therapeutic activities, however, remain largely unclear. Interestingly, recent studies have shown that fibroblast growth factor 21 (FGF21), a liver-derived hormone or hepatokine, mediates metabolic beneficial effects of certain dietary polyphenols as well as protein restriction. Here I have briefly summarized functions of FGF21, highlighted related dietary interventions, and presented literature discussions on role of FGF21 in mediating function of dietary polyphenol intervention and protein restriction. This is followed by presenting my perspective view, with the involvement of gut microbiota. It is anticipated that further breakthroughs in this field in the near future will facilitate conceptual merge of classical medicine and modern medicine.
Education Mismatch and Wages in Mauritius: Premium or Penalty
Authors: Ragoobur Verena Tandrayen 
Published: September 2022

AbstractThe paper investigates into the link between education mismatch and wages in Mauritius. It adds to the existing literature on education mismatch and labour market outcomes by using Mauritius as a case study in Africa, where overeducation is a growing concern, with graduates struggling to find jobs corresponding to their education level and field, the so-called vertical and horizontal mismatches. This supply-demand inadequacy ascends from a mix of factors and one of them can be termed as the ‘diploma disease’. Using the Continuous Multi-Purpose Household Surveys from 2013 to 2017, the pooled estimation results find evidence for a wage penalty of 1.3% for overeducated individuals compared to perfectly matched workers. A wage penalty of around 9.6% is also noted for undereducated workers compared to their perfectly matched counterparts. Heckman two step estimation approach is adopted to account for sample selection bias whilst the instrumental variable two stage least squares is applied to cater for the endogeneity of overeducation. The wage penalty for overeducation and undereducation under Heckman estimation method compares to ordinary least squares estimates with slight differences in the magnitude of the wage penalty. Once we account for endogeneity, the wage penalty for overeducated workers rose to 11% while that of overeducation did not change.

A baranyai településtörténeti irodalom könyvészeti jellemzői (1891-2021)
Authors: Erdős Zoltán 
Published: September 2022

Közhelyes megállapítás, hogy a társadalmi kohézió erősödésének és ezáltal a társadalmi kapacitás bővülésének fontos eleme a szilárd és gazdag helyi identitás, amihez nélkülözhetetlen szűkebb pátriánk örökségének ismerete és hagyományainak megélése. Ennek eszköze lehet a közösségi alkalmak szervezése, emlékhelyek kialakítása, helyismereti gyűjtemények létrehozása, vagy akár az adott település történetének megírása.
A tanulmány Baranya településtörténeti irodalmának könyvészeti jellemzőit elemzi. A helytörténeti művek időbeli és térbeli megoszlásának vizsgálata arra utal, hogy a leszakadó térségek települései, illetve az apró- és törpefalvak rendelkeznek legkisebb arányban helytörténeti feldolgozásokkal. Az összképet tovább rontja, hogy szemmel láthatóan a szakmai és a technikai színvonal is ezen munkák esetében a legalacsonyabb, viszont itt a legmagasabb a jellemzően szakdolgozatként készült, azaz nem publikált, az olvasók kezébe el sem jutó falutörténetek aránya. A helyzet tehát éppen ott a legrosszabb, ahol a legnagyobb szükség lenne a múlt értékeinek és a jövő perspektíváinak felmutatására.
A tanulmány a levont következtetések alapján szakmai, szakpolitikai javaslatokat fogalmaz meg. Szükség volna mindenekelőtt arra, hogy a vidékfejlesztési támogatások rendszerében megjelenjenek a helyi identitás erősítésével kapcsolatos tevékenységek, így – más tevékenységtípusokkal összehangolva – a helytörténeti művek elkészítése. A tapasztalatok szerint különösen sikeresek és költséghatékonyak lehetnek a kistáji szemléletű munkák. Emellett fontos volna megerősíteni a megyei közgyűjtemények kutatástámogató szerepét. A javaslatok célja, hogy elősegítsék a településtörténeti kutatások mennyiségi és minőségi gyarapodását, és ezáltal hozzájáruljanak a jelenleginél egészségesebben fejlődő, erősebb helykötődéssel bíró közösségek kialakulásához.
Strength Classification and Diagnosis: Not All Strength Is Created Equal
Authors: James Lachlan P. , Talpey Scott W. , Young Warren B. , Geneau Mary C. , Newton Robert U. , Gastin Paul B. 
Published: September 2022

ABSTRACT
Maximal force can be expressed across a range of conditions influenced by the external load and the time available to express force. As a result, several distinct and specific strength qualities exist. Conversely, some expressions of maximal force are similar and can be categorized as a single quality. Therefore, strength assessment systems must be sophisticated enough to isolate and measure each quality while minimizing redundant information. This article presents a contemporary, evidence-based and practical framework that reduces the many strength and speed-strength metrics into 5 distinct qualities. Alongside this, we present case examples of the application of strength diagnosis.

Published: September 2022

In this paper, the investigation of the crystal structure and electrophysical properties of Co/Ru/Co/Sub three-layer film systems with a Ru layer thickness dRu = 5-20 nm has been carried out. It is shown that for both as-deposited and annealed at 800 K thin-film samples the phase composition corresponds to hcp-Co + hcp-Ru. The dependence of resistivity and temperature coefficient of resistance as a function of dRu was received. It was demonstrated that the change in the resistivity value during the first cycle of heat treatment stays more significant than more Ru layer thickness. The value of temperature coefficient of resistance has an order of 10-4 and growth from 5.05×10-4 to 6.42×10-4 K-1 within the dRu range 0-20 nm.

It is unknown whether febrile infants 29 to 60 days old with positive urinalysis results require routine lumbar punctures for evaluation of bacterial meningitis.

OBJECTIVE
To determine the prevalence of bacteremia and/or bacterial meningitis in febrile infants ≤60 days of age with positive urinalysis (UA) results.

METHODS
Secondary analysis of a prospective observational study of noncritical febrile infants ≤60 days between 2011 and 2019 conducted in the Pediatric Emergency Care Applied Research Network emergency departments. Participants had temperatures ≥38°C and were evaluated with blood cultures and had UAs available for analysis. We report the prevalence of bacteremia and bacterial meningitis in those with and without positive UA results.

RESULTS
Among 7180 infants, 1090 (15.2%) had positive UA results. The risk of bacteremia was higher in those with positive versus negative UA results (63/1090 [5.8%] vs 69/6090 [1.1%], difference 4.7% [3.3% to 6.1%]). There was no difference in the prevalence of bacterial meningitis in infants ≤28 days of age with positive versus negative UA results (∼1% in both groups). However, among 697 infants aged 29 to 60 days with positive UA results, there were no cases of bacterial meningitis in comparison to 9 of 4153 with negative UA results (0.2%, difference -0.2% [-0.4% to -0.1%]). In addition, there were no cases of bacteremia and/or bacterial meningitis in the 148 infants ≤60 days of age with positive UA results who had the Pediatric Emergency Care Applied Research Network low-risk blood thresholds of absolute neutrophil count &lt;4 × 103 cells/mm3 and procalcitonin &lt;0.5 ng/mL.

CONCLUSIONS
Among noncritical febrile infants ≤60 days of age with positive UA results, there were no cases of bacterial meningitis in those aged 29 to 60 days and no cases of bacteremia and/or bacterial meningitis in any low-risk infants based on low-risk blood thresholds in both months of life. These findings can guide lumbar puncture use and other clinical decision making.
Fragment of Simonides (5,2 Bergk) in Julian the Apostate's Caesares
Authors: Csízy Katalin 
Published: September 2022

Abstract
The study investigates one arresting detail in Julian's Caesars (333B) that is related to Marcus Aurelius: “four-square and made without a flaw” – τετράγωνος ἄνευ ψόγου τετυγμένος. The central concern is to examine the background which could have influenced Julian's Neoplatonic thoughts in the 4th century AD by the Syrian Neoplatonist, Iamblichus. Marcus Aurelius as a symbol of perfection in Julian's opinion is another interesting question that needs to be answered.
PR + RQ &asymp; PQ: Transliteration Mining Using Bridge Language

Published: September 2022

We address the problem of mining name transliterations from comparable corpora in languages P and Q in the following resource-poor scenario:Parallel names in PQ are not available for training. Parallel names in PR and RQ are available for training.We propose a novel solution for the problem by computing a common geometric feature space for P,Q and R where name transliterations are mapped to similar vectors. We employ Canonical Correlation Analysis (CCA) to compute the common geometric feature space using only parallel names in PR and RQ and without requiring parallel names in PQ. We test our algorithm on data sets in several languages and show that it gives results comparable to the state-of-the-art transliteration mining algorithms that use parallel names in PQ for training.
In Defense of Large Qualitative Calculi
Authors: Li Jason , Renz Jochen 
Published: September 2022

The next challenge in qualitative spatial and temporal reasoning is to develop calculi that deal with different aspects of space and time. One approach to achieve this is to combine existing calculi that cover the different aspects. This, however, can lead to calculi that have a very large number of relations and it is a matter of ongoing discussions within the research community whether such large calculi are too large to be useful. In this paper we develop a procedure for reasoning about some of the largest known calculi, the Rectangle Algebra and the Block Algebra with about 10661 relations. We demonstrate that reasoning over these calculi is possible and can be done efficiently in many cases. This is a clear indication that one of the main goals of the field can be achieved: highly expressive spatial and temporal representations that support efficient reasoning.
Movimentos animistas no colonialoceno
Authors: Greco Lucrecia Raquel , Dodji Sanouvi Anani 
Published: September 2022

Apresentamos o método de pesquisa artística animista Agama Fo, criado pelo artista Ewe Anani Sanouvi, como una proposta de epistemologia e pesquisa antropológica que contesta parâmetros coloniais, etnocêntricos, androcêntricos e logocêntricos. Ao mesmo tempo, considerando a antropologia como um modo de pensar as possibilidades de existência dos seres humanos, entendemos este modo de conhecimento também como uma práxis micro/cosmpolítica particular que questiona a noção e experiência colonialocénica de individuo antropocêntrica capitalista e treina humanes sensíveis ao seu lugar no mundo como seres da e na terra.
Situades no diálogo entre a proposta de performance pesquisa em antropologia, os estudos da performance e a prática e transmissão de Agama Fo exploramos como experiências animistas/corporais como esta podem ser “boas para sentir/pensar” problemas antropológicos. Neste sentido destacamos a condição encarnada e situada das nossas imaginações socioantropológicas, contestamos standpoints logocéntricos e estimulamos a expansão dos modos somáticos de atenção na produção de conhecimento. Enfatizamos o modo em que a epistemologia de Agama Fo envolve a formação de mediadores não antropocentriques, ligades com temporalidades cíclicas e ancestrais que buscam construir refúgios situades em geopolíticas colonialocénicas.
