Ultra-compact integrated terahertz modulator based on a graphene metasurface
Authors: Kim Myunghwan , Kim Sangin , Kim Soeun 
Published: December 2020

We propose a new type of a mid-infrared ultra-compact optical modulator
composed of a graphene metasurface. Unlike the previously proposed
schemes based on loss variation of materials or interference, the
proposed one utilizes the unique topological characteristic of the
isofrequency contour in the hyperbolic metasurface to modulate the
transmission. The designed modulator provides a modulation depth of
10.7 dB, the length of which is 750 nm, corresponding to

Academics' conceptions of and approaches to research-teaching linkages: Challenges for realising the curriculum as praxis
Authors: Rayner Michael , Smyth Keith , Fotheringham Heather 
Published: December 2020

In this paper, we seek to provide a rich exploration of the conceptions of and approaches to research-teaching linkages (RTL) that are held and undertaken by scholars, researchers and academics within Higher Education (HE). The work we report has been undertaken as part of a longitudinal institutional project to broaden and deepen engagement with RTL in a geographically distributed university that sits within a particular social and economic context. The project has a primary focus on exploring creative new ways to embed RTL principles and practices across a broad range of subject areas, within formal learning and teaching, and curricula, in such a way that the intellectual work our students undertake and produce has a direct value to the needs of the wider communities the university serves.
Within this paper, we present key aspects of our work and findings to date in three distinct parts. Part 1 summarises the main findings from an extensive review of the literature related to RTL that we undertook, and in which we synthesise the literature on RTL into four distinct areas comprising: perceptions of RTL; principles of RTL; productivity in RTL, and practice in RTL. In the latter area we consider the concept of the ‘curriculum as praxis’. Part 2 of the paper describes and reports on the emerging findings of our own research, which took the form of a phenomenographic study investigating the conceptions of and approaches to RTL within the range of staff who are participating in the aforementioned institutional project. The phenomenography represents a contribution to a relatively small research base of phenomenographic research concerning RTL. In Part 3 of the paper we consider and look towards how we reconcile the promise and possibilities of RTL, particularly in relation to the ‘curriculum as praxis’, with the perceptions and practices emerging from our phenomenographic study. In doing so we offer a consideration of practical next steps that we are now taking, including recommendations we hope others may find useful.
Some integral curves with a new frame
Authors: Güven İlkay Arslan 
Published: December 2020

Abstract
In this paper, some new integral curves are defined in three-dimensional Euclidean space by using a new frame of a polynomial spatial curve. The Frenet vectors, curvature and torsion of these curves are obtained by means of new frame and curvatures. We give the characterizations and properties of these integral curves under which conditions they are general helix. Also, the relationships between these curves in terms of being some kinds of associated curves are introduced. Finally, an example is illustrated.
THE ALGUNAS CONSIDERACIONES ÉTICAS SOBRE LA APLICACIÓN DE LA INTELIGENCIA ARTIFICIAL EN EL DEPORTE
Authors: CARRIO SAMPEDRO Alberto 
Published: December 2020

La inteligencia artificial (IA) ha irrumpido recientemente en el deporte, pero sus aplicaciones ocupan ya un lugar destacado en la práctica deportiva e irán sin en aumento en los próximos años. Son muchos los beneficios que estos sistemas de tecnología avanzada pueden proporcionar al deporte. Pero las aplicaciones de la IA en el deporte no están exentas de riesgos. Entre ellos, la manipulación de los deportistas y de la competición son probablemente los más acuciantes. Pero hay otros, como la modificación radical de la gobernanza del deporte y las competiciones deportivas que quedarán completamente mediatizadas por esta tecnología disruptiva. En este artículo propongo un marco jurídico y ético que nos permita disponer de un uso fiable de la IA y respetuoso con los derechos humanos de los deportistas y los compromisos éticos del Movimiento Olímpico.
O negacionismo renovado e o ofício do Historiador
Authors: Jesus Carlos Gustavo Nóbrega de , Gandra Edgar Avila 
Published: December 2020

O intuito de tal artigo é entender a ampliação do conceito “negacionismo” que, nos últimos anos, não ficou restrito à contestação da existência do Holocausto, mas ampliou-se para outras áreas do saber, tanto dentro como fora da História. Diante de tal perspectiva ampla salienta-se a repercussão da narrativa negacionista no campo historiográfico, levantando-se a hipótese que a necessidade de se contrapor a tal discurso levou a um embate epistemológico dentro da disciplina, ainda no final dos anos 1990. A partir daí pretende-se averiguar como a narrativa negacionista ganhou legitimidade nos últimos dez anos por meio das redes sociais e da ascensão de políticas conservadoras, salientando a importância do papel ativo dos historiadores e de seu ofício nesse momento marcado pela necessária tomada de posição frente à disseminação de tais leituras proselitistas acerca do passado.

Authors: Balasubramanian S. , Shukla Vikash , Singh Rongen 
Published: December 2020

Background: Generally, roasting of any food grains or legumes are carried out to improve the palatability and to improve the special characteristics like physical texture, colour and etc., Methods: This study was carried out to optimize the process parameter for soaked soybean splits in an open type LPG gas assisted soybean roaster using response surface methodology with process variables viz., soaking time and roasting time. The capacity of soybean roaster is 15 kg/batch, rotating drum speed with 24 rpm and power operated with a 0.5 hp electric motor. A central composite rotatable design (CCRD) was used to select variables level i.e. soaking time (60-180 min) and roasting time (4-10 min).Result: The effect of moisture content on some physical properties of soybean seed and split were determined. The results showed that the roasted soybean splits increased linearly in length, width, thickness, arithmetic mean diameter, geometric mean diameter, square mean diameter, equivalent diameter, unit volume and surface area, where in sphericity, aspect ratio and shape factor decreased linearly with the increase in moisture content of soybean splits. The process variable had a significant effect on Hunter color and textural properties. The optimized soaking time and roasting time in the developed roaster is 123.362 min and 7.702 min, respectively.

Background: Disruption through present pandemic is applicable to almost all the sectors of economy. However, impact on Indian food and dairy industry is largely experienced considering it as the livelihood of sizable stakeholders emphasizing small and marginal farmers. Present study is undertaken to examine the global assessment of dairy supply chain with emphasizing on India, USA and Canada, which will be important to observe positive and negative trends of Covid-19 and suggesting appropriate measures for dealing with present and similar situations in near future.Methods: Systematic literature review assessment had been followed from major web platforms like Jgate, Ebsco database and popular news articles were explored since December 2019 to April 2020 for the study purpose. Conclusion: Along with supply chain assessment through its various components, it was observed that although different countries have negative effect on the dairy communities, but these adverse situations can be converted into new possibilities for expansion. It was also observed that dairy industry has the potential to convert present crisis into opportunity thereby not only concentrating on health part of consumers but also contributing towards generating employment.
Metacognition and Ruminative Thinking as Predictors of Burnout: A Structural Equation Modelling
Authors: EVLİ Mahmut , ŞİMŞEK Nuray 
Published: December 2020

Nursing education is a difficult process with both theoretical and clinical practice. This difficult process creates pressure and stress in nursing students. Therefore, students cannot notice emotions and thinking and may experience rumination. In this case, it can occur in burnout in addition to many mental illnesses. The aim of this study was to investigate whether metacognition and rumination had a predictive effect on burnout. The sample of the study consisted of 280 nursing students who volunteered to participate in the study, and it was completed with 261 nursing students who completed the measurement tools completely. Data were collected using an introductory information form, Ruminative Thinking Style Scale, Metacognitions Questionnaire 30, and Maslach Burnout Inventory. Correlation analysis and structural equation modeling were used to analyze the data. It was determined Ruminative Thinking averages of the participants was 87.61 ± 2.59, Total Metacognitions averages 73.96 ± 11.80, Emotional Exhaustion averages 24.63 ± 5.55, Depersonalization averages 9.58 ± 2.79, Personal average 28.54 ± 5.34. In this study, it is seen that high metacognitions and ruminative thinking styles of students affect burnout. But ruminative thinking has not a mediating role in the relationship between metacognitions and burnout.
PENTECOSTALIZAÇÃO ASSENTADA NO ASSENTAMENTO ZUMBI DOS PALMARES, CAMPOS DOS GOYTACAZES, RJ
Authors: Py Fábio , Pedlowski Marcos A. 
Published: December 2020

O artigo destaca o crescimento pentecostal vivenciado no assentamento Zumbi dos Palmares, em Campos dos Goytacazes, que fica localizado na região Norte Fluminense. Neste assentamento, em pouco mais de 20 anos de existência, o número de evangélicos pentecostais passou de 7% a 75% dos integrantes, modificando a configuração religiosa do assentamento, que apresentava significativa maioria católica nos anos próximos à sua fundação. No artigo, se destaca a mobilidade religiosa, na qual realça a perda de força do catolicismo popular e o crescimento do pentecostalismo no assentamento. No trabalho, se adaptará o conceito de mecanismo de desencaixe, definido por Antony Giddens, para descrever a intensa mobilidade religiosa no assentamento como o processo “desencaixe” dos sujeitos ante determinada dinâmica social e o posterior “reencaixe” em nova conexão social. Para tanto, se utilizará tanto da metodologia quantitativa, quanto de metodologias qualitativas, como entrevistas semiestruturadas e a observação participante.

In order to be widely used by users of financial statements, information related to tax receivable accounts in LKPP must meet the Full Disclosure Principle relate to assets, liabilities and equity either through faces or Notes to Financial Statements. Complete information will prevent users from misleading and improper decision making or opinions on the financial condition and performance of the central government. This study focuses on the disclosure of information on tax accounts receivable at LKPP because the account has significant value and gets the attention of LKPP users. Through this research, the writer will assess whether the information related to tax receivables in LKPP FY 2017 to 2019 meets the Full Disclosure Principle. To fulfill the principle, LKPP must disclose 9 adequate information related to tax receivable. The results of the analysis show that the disclosure of tax receivables in LKPP FY 2017 and LKPP FY 2018 don’t fulfill all the criteria, while LKPP FY 2019 only fulfill 1 criteria. There was no significant increase in the implementation of full disclosure principle of tax receivable within 3 years.
Electricity Consumption of Singaporean Households Reveals Proactive Citizen Response to COVID-19 Progression
Authors: Raman Gururaghav , Peng Jimmy Chih-Hsien 
Published: December 2020

Abstract
Understanding how populations’ daily behaviors change during the COVID-19 pandemic is critical to evaluating and adapting public health interventions. Here, we use residential electricity consumption data to unravel behavioral changes within citizens’ homes in this period. Based on smart energy meter data from 10,246 households in Singapore, we find strong correlations between the pandemic progression in the city-state and the residential electricity consumption. In particular, we find that the daily new COVID-19 cases constitute the most dominant influencing factor on the electricity demand in the early stages of the pandemic, before a lockdown. However, this influence wanes once the lockdown is implemented, signifying the arrival of a ‘new normal’ in the residents’ lifestyles. These observations point to a proactive response from Singaporean residents---who increasingly stayed at home during evenings despite not being forced by the government to do so using a lockdown---a finding that surprisingly extends across all demographics. Overall, our study enables policymakers to close the loop by utilizing residential electricity usage as a measure of community response during unprecedented and disruptive events such as a pandemic.

Abstract
Background: Hepatocellular carcinoma (HCC) is a common malignancy of the digestive system. A novel long non-coding RNA, ENSG00000236199 (lncRNA-199) , whose role in tumors has not been reported, especially in HCC. Methods: The expression of lncRNA-199 and miR-576-5p were detected by Real-time quantitative polymerase chain reaction (RT-qPCR), NRIP1 was measured by Western blotting. HCC cell proliferation and metastasis of HCC were examined using functional tests. Luciferase reporter assay was performed to confirm the relationship between lncRNA-199 and miR-576-5p, between miR-576-5p and NRIP1. Results: LncRNA-199 was frequently down-regulated in HCC and this down-regulation was negatively correlated with prognosis. Overexpression of lncRNA-199 could inhibit the growth and metastasis of HCC, while knockdown lncRNA-199 had the opposite effect. Down-regulated lncRNA-199 also could induce epithelial-mesenchymal transformation (EMT). Luciferase reporter assay demonstrated lncRNA-199 could modulate NRIP1 by sponge miR-576-5p. Conclusion: LncRNA-199 inhibited growth and metastasis through miR-576-5p/NRIP1 axis in HCC. This study revealed a novel unknown lncRNA function in malignant tumors, especially in HCC. At the same time, the regulatory mechanism of lncRNA-199 in HCC was clarified.

Published: December 2020

Abstract
Background: It is usually common for liposarcoma as one of the soft tissue sarcomas to be found in adults, and the disease in children is the rare case. Case presentation: This article involves in a 14-year-old boy with a primary posterior mediastinal atypical lipomatous tumor. It also provides a literature review and summary for the disease with the aim of making the disease well learned, because of the absence of the uniform standards for the clinical features, diagnostic methods, best treatment methods, and clinical efficacy of the atypical lipomatous tumor.Conclusion: Complete surgical resection is the best method for the eradication of tumors. However, mediastinal liposarcoma can not be completely removed by surgery in some cases. For the treatment of residual tumor tissue, molecular inhibitors will be an important supplementary method for the treatment of liposarcoma in the future.

Published: December 2020

Abstract
Background: While the first case of COVID-19 was declared on March 2 2020 in Senegal, the government banned the attendance of places of worship on 14 March. On March 23, it introduced a curfew, a ban on movement between regions, and the closure of markets. These measures were lifted in May and June 2020. The objective of this study is to measure and understand the acceptability of these four governmental measures as well as the level of public trust in the state to fight the pandemic. Methods: We carried out a mixed-method research with an explanatory sequential estimate. The acceptability variables were defined using the theoretical framework of acceptability (TFA). At the quantitative level, we carried out a telephone survey (June/July 2020) at the national level (n=813) with a sampling strategy by marginal quotas. To understand these results, we conducted a qualitative survey (August/September 2020) with a nested sample (n=30). Results: The results show a relatively high acceptability of the measures but a heterogeneity of responses. People considered curfews to be much more important (85.7% [83.2%; 88.0%]) than the closure of places of worship (55.4%; [51.9%; 58.7%]), which is least in line with the values and positive affective attitude. With the lifting of certain measures, respondents questioned the consistency of the decisions. Several positive unintended effects of the curfew were stated (security and social/family cohesion). People over the age of 60 have more confidence in the government to fight the pandemic than people under the age of 25 (7.72 ± 3.12 vs. 7.07 ± 3.11, p = 0.1); and they are more in favour of the closure of places of worship. Men have less confidence in the government than women (6.84 ± 3.21 vs. 7.47 ± 3.05; p = 0.001). The more regions are affected by the pandemic, the less confidence respondents report in the government and the less they perceive the measures as effective.Conclusions: The results confirm the importance of government communication and trust in the state to strengthen the acceptability of pandemic measures. Important differences in acceptability show the need to adapt measures and their explanations, instead of unqualified universal action.

Published: December 2020

Abstract
Background: Prader Willi Syndrome (PWS) is a genetic disorder caused by the absence of expression of the paternal copies of maternally imprinted gene(s) located at 15q11–q13. While the physical and medical characteristics of PWS, including short stature, hyperphagia and endocrine dysfunction are well-characterized, systematic investigation of the long-recognized psychiatric manifestations has been recent. Methods: Here, we report on the first remote (web-based) assessment of neurobehavioral traits, including psychotic-like experiences (Prodromal Questionnaire-Brief Version; PQ-B) and sleep behavior (Pittsburgh Sleep Quality Index), in a cohort of 127 participants with PWS, of whom 48% had a paternal deletion, 36% uniparental disomy, 2.4% an imprinting mutation and 13% unknown mutation (mean age 19.2 years+/-8.4 years; 55.2% female). We aimed to identify the most informative variables that contribute to psychosis risk symptoms. Multiple domains of cognition (accuracy and speed) were also assessed in a subset of PWS participants (N=39) using the Penn Computerized Neurocognitive Battery (Penn-CNB). Results: Sleep disturbance, particularly the reasons for sleep difficulty, was most strongly associated with distress related to psychotic-like symptoms. Regarding cognition, individuals with PWS showed the most prominent deficits in accuracy on measures of social cognition involving faces, namely Face Memory, Age Differentiation and Emotion Recognition, and greatest slowing on measures of Attention and Emotion Recognition. However, there were no significant differences in psychotic-like experiences or cognitive performance as a function of PWS genetic subtype. Conclusion: Findings indicate that self/parent-reported neurobehavioral symptoms and cognition can be assessed remotely in individuals with PWS, which has implications for future large-scale investigations of rare neurogenetic disorders. Trial registration: Not applicable.
