Effect of serrated trailing edges on aerofoil tonal noise

Abstract A wall-resolved large-eddy simulation of a symmetric Joukowski aerofoil with a 12 % thickness at a Reynolds number of 250 000, a Mach number of 0.4 and zero incidence angle is performed in order to investigate the effect of using a serrated trailing edge on the acoustic feedback event that generates a tonal noise. The acoustic feedback is investigated in detail to emphasise the interaction between the upstream travelling acoustic expansion wave and the laminar separation bubble. The simulation shows that the serrated trailing edges may result in a significant reduction of the tonal noise. This paper provides detailed investigations into the noise reduction mechanisms. The main finding is that the presence of a serrated trailing edge decreases the amplitude of the acoustic source pressure in the transitional region and gives rise to destructive phase interference in the wall pressure fluctuations in the vicinity of the trailing edge which weakens the acoustic feedback loop.
The Rise of Pop-Up Retail: Investigating the Success of Experiential Design within Pop-Up Stores

The purpose of this paper is to explore design factors behind successful pop-up shops and how design elements in these environments can enhance the consumer experience. Since pop-up shops are defined as “impermanent” environments, the connection between the consumer experience and design elements such as colors, lighting, materiality, form, and layout can have a meaningful impact in raising brand awareness and potentially influence sales. This exploratory and qualitative research collected data based on direct observations of six pop-up retail stores in the New York City region. This study provides better insight to designers and companies on the importance of design strategies within environments in this quickly growing industry to create memorable experiences for consumers.
Improving Breast Cancer Detection Accuracy of Mammography with the Concurrent Use of an Artificial Intelligence Tool.

Purpose To evaluate the benefits of an artificial intelligence (AI)-based tool for two-dimensional mammography in the breast cancer detection process. Materials and Methods In this multireader, multicase retrospective study, 14 radiologists assessed a dataset of 240 digital mammography images, acquired between 2013 and 2016, using a counterbalance design in which half of the dataset was read without AI and the other half with the help of AI during a first session and vice versa during a second session, which was separated from the first by a washout period. Area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and reading time were assessed as endpoints. Results The average AUC across readers was 0.769 (95% CI: 0.724, 0.814) without AI and 0.797 (95% CI: 0.754, 0.840) with AI. The average difference in AUC was 0.028 (95% CI: 0.002, 0.055, P = .035). Average sensitivity was increased by 0.033 when using AI support (P = .021). Reading time changed dependently to the AI-tool score. For low likelihood of malignancy (< 2.5%), the time was about the same in the first reading session and slightly decreased in the second reading session. For higher likelihood of malignancy, the reading time was on average increased with the use of AI. Conclusion This clinical investigation demonstrated that the concurrent use of this AI tool improved the diagnostic performance of radiologists in the detection of breast cancer without prolonging their workflow.Supplemental material is available for this article. © RSNA, 2020.
Session-to-session variations in external load measures during small-sided games in professional soccer players

The aims of this study were 1) to analyse session-to-session variations in different external load measures and 2) to examine differences in within-session intervals across different small-sided game (SSG) formats in professional players. Twenty professional soccer players (mean ± SD; age 28.1 ± 4.6 years, height 176.7 ± 4.9 cm, body mass 72.0 ± 7.8 kg, and body fat 10.3 ± 3.8%) participated in 3v3, 4v4, and 6v6 SSGs under different conditions (i.e., touch limitations and presence of goalkeepers vs. free touch and ball possession drill) over three sessions. Selected external load measures—including total distance (TD), high-intensity running (HIR, distance covered > 14.4 km.h-1), high-speed running (HSR, distance covered > 19.8 km.h-1), and mechanical work (MW, accelerations and deceleration > 2.2 m.s2)—were recorded using GPS technology during all SSG sessions. Small to large standardized typical errors were observed in session-to-session variations of selected measures across SSGs. TD.min-1 showed less variability, having a coefficient of variation (CV) of 2.2 to 4.6%, while all other selected external load measures had CV values ranging from 7.2% to 29.4%. Trivial differences were observed between intervals in TD.min-1 and HIR.min-1 for all SSGs, as well as in HSR.min-1 and MW.min-1 for most SSG formats. No reductions or incremental trends in session-to-session variations were observed when employing touch limitations or adding goalkeepers. The increased noise observed in higher speed zones (e.g., high-speed running) suggests a need for more controlled, running-based conditional drills if the aim is greater consistency in these measures.
Effect of Weed Management Practices on Weed Growth and Yield of Greengram (Vigna radiata (L.) Wilczek) in Southern Rajasthan

A Field experiment was conducted at Agronomy instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan) during 2016-17 to find out the impact of new generation herbicides in green gram. The results revealed that all growth and yield characters of blackgram were significantly affected by distinct weed control practices. A similar trend was also observed in weed parameters. Higher seed yield (13.8 qha-1) and higher weed control efficiency (88.97%) were recorded under application of acifluorfen sodium + clodinafop propargyl (370 g a.i. ha-1) at 3-4 leaf stage and which comparable with pre-emergence application of pyroxasulfone +pendimethalin (TM) 127.5+1000 g a.i/ha, imazethapyr+ quizalofop (TM) use at 70 + 60 g a.i/ha at 3-4 leaf stage, imazethapyr 70 g a.i/ha 3-4 leaf stage, imazethapyr + imazamox (RM) use at 70 g a.i/ha at 3-4 leaf stage, pendimethalin fb quizalofop 1000 + 60 at pre-emergence & 3- 4 leaf stage, imazethapyr + pendimethalin (RM) 1000 g a.i/ha as pre-emergence, propaquizfop 75 g a.i/ha at 3-4 leaf stage, weedy check and two hand weeding twice at 20 & 40 DAS. They also recorded improvement in yields and net returns by 65.22% over weedy check. These herbicide ready-mixes may be a promising weed management strategy for the green gram grown in the Southern Rajasthan.
The FastEddy® Resident‐GPU Accelerated Large‐Eddy Simulation Framework: Model Formulation, Dynamical‐Core Validation and Performance Benchmarks

This paper introduces a new large‐eddy simulation model, FastEddy®, purpose built for leveraging the accelerated and more power‐efficient computing capacity of graphics processing units (GPUs) toward adopting microscale turbulence‐resolving atmospheric boundary layer simulations into future numerical weather prediction activities. Here a basis for future endeavors with the FastEddy® model is provided by describing the model dry dynamics formulation and investigating several validation scenarios that establish a baseline of model predictive skill for canonical neutral, convective, and stable boundary layer regimes, along with boundary layer flow over heterogeneous terrain. The current FastEddy® GPU performance and efficiency gains versus similarly formulated, state‐of‐the‐art CPU‐based models is determined through scaling tests as 1 GPU to 256 CPU cores. At this ratio of GPUs to CPU cores, FastEddy® achieves 6 times faster prediction rate than commensurate CPU models under equivalent power consumption. Alternatively, FastEddy® uses 8 times less power at this ratio under equivalent CPU/GPU prediction rate. The accelerated performance and efficiency gains of the FastEddy® model permit more broad application of large‐eddy simulation to emerging atmospheric boundary layer research topics through substantial reduction of computational resource requirements and increase in model prediction rate.
“Houston, we have a problem”: Revealing MOOC practitioners' experiences regarding feedback provision to learners facing difficulties

In spite of the high impact of Massive Open Online Courses (MOOCs), learners frequently disengage from the course contents and activities due to unexpected problems of different natures, such as content‐related or technical issues. Feedback has been identified as an important aspect of the learning process directly connected with learners' engagement. However, the massive and impersonal nature of MOOCs hinders the provision of efficient and timely feedback to those learners facing problems. This paper examines how MOOC practitioners identify and support learners facing problems, what challenges they encounter, and what strategies they apply to overcome such challenges. Additionally, the current study aims to compare the learners' problems and practitioners' experiences between engineering‐related and nonengineering related MOOCs. A qualitative phenomenological study has been conducted through semistructured interviews with 14 MOOC practitioners. The evidence gathered shows diverse learners' and practitioners' problems shared among engineering and nonengineering courses and a general concern on how to address individual learners' needs in time. A common practice of problem identification regards checking the self‐reported issues in communication forums. Identification strategies with the use of learning analytics are limited due to platform restrictions or lack of practitioners' skills in interpreting the provided information. The synthesis of MOOC practitioners from both engineering and nonengineering disciplines may provide insights that are either globally applicable to all disciplines or specific to engineering. The results could be shaped into conceptual and technological solutions to help MOOC stakeholders (e.g., researchers, practitioners) identify potential learners facing difficulties and support them during the course process.
School Climate, Peer Relationships, and Adolescent Mental Health: A Social Ecological Perspective

The current study investigated peer relationship and school climate factors associated with adolescent mental health. Cross-sectional data from 2,571 fifteen-year old students in 22 Scottish secondary schools was used. Multilevel models tested for school differences in mental health, and nested linear regression models estimated peer and school effects. Results demonstrated no significant between-school variation in mental health. Peer victimization was the only peer effect associated with mental health. School-belonging, student-teacher relationships, and a perceived inclusive school climate were associated with better mental health, whereas a perceived school climate of exam pressure was associated with worse mental health. The findings highlight multiple aspects of school climate that could be targeted in school-based interventions for adolescent mental health.
Suspicion of Welfare Overuse in Sweden: The Role of Left–Right Ideology, Anti‐Immigrant Attitudes and Gender

In this study, we explore individual differences in suspicion of welfare overuse in Sweden. Focusing on previously underdeveloped areas, we find that the hitherto observed negative relationship between political interest and suspicion of welfare overuse is only valid for those who sympathize with political parties to the left (and to a lesser extent the Green Party). Conversely, individuals who sympathize with centre-right parties or right-wing populists differ little internally depending on their level of political interest. We also find a strong positive correlation between anti-immigrant attitudes and suspicion about welfare overuse. Finally, we find that women are less suspicious of welfare overuse than men are, and that this cannot be attributed to gender differences in material risks or resources, education, experiences of welfare services, general trustfulness, anti-immigrant sentiment or political orientation. Neither do gender differences vary according to strength of gender identification. Thus, being suspicious about welfare overuse is not likely to be perceived as a typically masculine or feminine posture. Based on our findings, we argue that future studies exploring partisan or ideological differences in perceptions of welfare overuse need to consider these in conjunction with political interest and political context; that rising anti-immigrant sentiments pose a particularly serious threat to the legitimacy of welfare states, given their strong connectedness to suspicion of welfare overuse; and that gender differences in perceptions of welfare overuse are more fruitfully addressed through a lens of gender relations, rather than gender role stereotypes.

Modelling Maize Yield and Water Requirements under Different Climate Change Scenarios

African countries such as Nigeria are anticipated to be more susceptible to the impacts of climate change due to large dependence on rainfed agriculture and to several uncertainties in the responses of crop production to climate change. The impacts of climate change on crop water requirements (CWR), irrigation water requirements (IWR), yields and crop water productivity (CWP) of rainfed maize in Ogun-Osun River Basin, Nigeria were evaluated for a baseline period (1986–2015) and future projection period (2021–2099) under Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 scenarios. For the baseline period, there is no significant trend within the variables studied. However, IWR is projected to increase significantly by up to 140% in the future period, while yield might likely decline under both scenarios up to −12%. This study shows that in the future periods, supplemental irrigation has little impact in improving yields, but an increase in soil fertility can improve yields and CWP by up to 80% in 2099. This paper offers useful information on suitable adaptation measures which could be implemented by stakeholders and policymakers to counterbalance the effects of climate change on crop production.
Effects of a novel E. coli phytase expressed in Pseudomonas fluorescens on growth, bone mineralization, and nutrient digestibility in pigs fed corn–soybean meal diets

Abstract Two studies were conducted to determine the effects of a novel Escherichia coli phytase expressed in Pseudomonas fluorescens on growth performance, bone mineralization, and nutrient digestibility in pigs fed corn-soybean meal diets. In experiment 1, 160 nursery pigs (9.79 ± 1.22 kg) were randomly allotted to one of four treatments with 10 pens per treatment and four pigs per pen. Phase I and phase II diets were provided from d 0 to d 14 and d 14 to d 28, respectively. Treatments included: positive control (PC) with all nutrients meeting requirements; negative control (NC) with standardized total tract digestible (STTD) P reduced by 0.15% and 0.14% compared with PC in phase I and phase II, respectively; and NC diets containing 250 or 500 units of phytase (FTU) per kilogram. Results demonstrated that pigs fed PC had greater (P < 0.01) ADG and G:F for the overall experimental period, and greater (P < 0.01) bone ash and P concentrations, compared with pigs fed NC or diets with phytase supplementation. Pigs fed diets containing phytase had greater (P < 0.01) ADG and G:F for the overall experimental period compared with pigs fed the NC diet without phytase, and bone ash and P weights were increased (P < 0.01) as well. In experiment 2, 63 growing barrows (56.25 ± 2.54 kg) were blocked by BW and randomly allotted to one of seven treatments with nine pens per treatment and one pig per pen. A basal corn–soybean meal diet was formulated to meet nutrient requirements for growing pigs with the exception that STTD P was reduced by 0.18% compared with the requirement, and Ca was included to achieve a Ca:STTD P ratio of 2.15. Six additional diets were formulated by adding 250, 500, 750, 1,000, 1,500, or 2,000 FTU/kg of phytase to the basal diet. Pigs were fed experimental diets for 12 d with 7 d of adaptation and 5 d of fecal sample collection. Results indicated that there was a linear (P < 0.01) increase in apparent total tract digestibility of ash and ether extract, and STTD of Ca and P also increased (linear, P < 0.05) in response to increasing doses of phytase. Increasing phytase levels in the diets resulted in increase (quadratic, P < 0.05) in apparent ileal digestibility of Arg, His, Ile, Lys, Trp, Asp, and Glu. In conclusion, the novel E. coli phytase was effective in increasing growth performance, bone mineralization, and Ca and P digestibility in pigs fed corn–soybean meal-based diets. Results also indicated that this phytase had the potential to enhance the digestibility of fat and certain AA.
HnRNP-F promotes the proliferation of bladder cancer cells mediated by PI3K/AKT/FOXO1

Our previous study showed that heterogeneous nuclear ribonucleoprotein F (hnRNP-F) could induce epithelial-mesenchymal transition and metastasis in bladder cancer (BC), however, the role and mechanism of hnRNP-F in mediating the proliferative ability of BC cells remain unclear. HnRNP-F promoted the proliferation of BC cells by using BC cell lines and cell counting kit-8 (CCK8), colony formation and flow cytometry assays in vitro. Furthermore, the association of hnRNP-F with the phosphoinositide 3‑kinase (PI3K)/protein kinase B (AKT) signalling pathway was confirmed by western blotting after bioinformatic analysis. HnRNP-F expression was significantly decreased by treatment with the PI3K/AKT signalling pathway inhibitor LY294002, whereas hnRNP-F knockdown did not significantly affect PI3K or AKT expression, suggesting that hnRNP-F is likely a downstream target of the PI3K/AKT pathway. Forkhead box O1 (FOXO1) is a molecule downstream of PI3K/AKT and can be inhibited by phosphorylation. In addition, chromatin immunoprecipitation (ChIP) and luciferase reporter assays indicated that FOXO1 expression was negatively correlated with hnRNP-F expression as FOXO1 was found to bind to the promoter region of hnRNP-F mRNA and inhibit its transcription. To sum up, our findings suggest that hnRNP-F expression is regulated by the PI3K/AKT-mediated phosphorylation of FOXO1, with phosphorylation inhibiting FOXO1, which subsequently allows hnRNP-F to promote proliferation. This finding is a novel discovery in BC and could help reveal the mechanism of BC progression.
Contemporary regionalism and The Scandinavian 8 Million City: spatial logics in contemporary region-building processes

ABSTRACT This paper shows how certain spatial logics are used to support contemporary region-building processes, and how these become taken for granted and institutionalized in specific regional settings. These spatial logics are also representative of the spatial logics dominating contemporary regionalism and affect the ways ‘spaces’ and ‘citizens’ are treated and valued in regional planning and policy. Few studies have shown how spatial logics are implemented, transformed and turned into policy across a wider set of regions. Exemplified by The Scandinavian 8 Million City project, the paper shows how this regional imaginary was constructed by the project promotors using several representative spatial logics of what constitutes the ‘best’ region as idealized in planning and policies.
‘It’s like it doesn’t really matter’: Are teachers accountable and equipped for teaching primary physical education?

ABSTRACT In light of the recent trend of outsourcing Physical Education teaching, the aim of this study was to examine primary teachers’ perspectives of primary Physical Education delivery. Fourteen in-service primary school teachers took part in semi-structured interviews. Thematic analysis led to the development of six themes. Findings were presented as a written playscript, representing dialogue between group primary school teachers, with reflections of four Physical Education subject leads included to supplement the dialogue. The findings suggest a greater emphasis on accountability, subject advocacy, teacher professional development and effective deployment of resources are needed to address the issues raised by the primary teachers.
The Role of Family Resilience on Parental Well-Being and Resilience Levels

Family well-being, conceptualized as the interaction between family members’ mental, physical health and psychological resilience, and family resilience, is crucial for the optimal functioning of the family unit. However, most research investigating the relationship between family resilience and psychological outcomes has focused on children instead of parents and no relevant research in the general Greek population has been conducted so far. Therefore, a sample of 83 Greek parents was recruited and the relationship of family resilience with parental well-being and parental resilience was examined. In addition, differences in the aforesaid constructs between mothers and fathers were explored. Results indicated that parents, who reported higher levels of coping strategies in terms of family resilience, were more likely to report higher levels of well-being and psychological resilience. Nevertheless, no significant differences in family resilience, parental well-being, and parental resilience between mothers and fathers were identified. Methodological limitations and future recommendations were discussed.
