The combination of optical fiber with graphene has greatly expanded the application regimes of fiber optics, from dynamic optical control and ultrafast pulse generation to high precision sensing. However, limited by fabrication, previous graphene-fiber samples are typically limited in the micrometer to centimeter scale, which cannot take the inherent advantage of optical fibers—long-distance optical transmission. Here, we demonstrate kilometers long graphene-coated optical fiber (GCF) based on industrial graphene nanosheets and coating technique. The GCF shows unusually high thermal diffusivity of 24.99 mm

in the axial direction, measured by a thermal imager directly. This enables rapid thermooptical response both in optical fiber Bragg grating sensors at one point (18-fold faster than conventional fiber) and in long-distance distributed fiber sensing systems based on backward Rayleigh scattering in optical fiber (15-fold faster than conventional fiber). This work realizes the industrial-level graphene-fiber production and provides a novel platform for two-dimensional material-based optical fiber sensing applications.

Studi ini membahas tentang penggunaan media sosial facebook bagi remaja laki-laki dalam menjalin hubungan pacaran. Teori utama yang digunakan yaitu Teori Pengurangan Ketidakpastian terkait konsep interaksi awal ketika awal pertemuan antar individu. Dalam teori pengurangan ketidakpastian, terdapat tiga alasan bahwa seseorang akan meningkatkan perhatian yang diberikan pada tindakan orang lain: insentif, penyimpangan, dan interaksi di masa depan. Yang pertama adalah ketika seseorang mengharapkan bahwa orang lain akan memberikan informasi yang berguna atau bentuk penghargaan lainnya. Yang kedua terjadi ketika seseorang bertindak dengan cara yang menyimpang. Terakhir, kemungkinan interaksi di masa depan dengan orang lain juga meningkatkan seberapa dekat kita memantau perilaku mereka untuk mengurangi ketidakpastian. Teori Pengurangan Ketidakpastian dipilih karena merupakan teori yang dapat diimplementasikan ketika telah terjadi interaksi awal dengan orang lain yang dipandu oleh komunikasi antar individu. Pendekatan kualitatif bersifat eksploratif yang dipakai dalam studi ini dan metodologi yang digunakan melalui wawancara mendalam. Hasil dari Penelitian ini menyimpulkan bahwa bahwa teori pengurangan ketidakpastian merupakan kerangka teoritis yang tepat untuk memahami peran Facebook dalam hubungan asmara remaja. Hasil menunjukkan bahwa pengurangan ketidakpastian aktif dikaitkan dengan strategi pengurangan ketidakpastian pasif dalam hubungan romantis seperti pemantauan online, ini sepenuhnya sesuai dengan rumusan teori pengurangan ketidakpastian

MATHEMATICAL EQUATION FOR IMPURITY DISTRIBUTION AFTER SECOND PASS OF ZONE REFINING
Authors: Skrobian Milan , Pernis Rudolf 
Published: March 2021

A mathematical equation has been derived that describes impurity distribution in ingot after second pass of zone refining. While an exponential impurity distribution is calculated by a simplified model after first pass, second pass is described by mixed linear - exponential model. Relationship of transformed impurity concentration is constant over whole length of semi-infinite ingot for first pass. However, it has linear trend for second pass. Last part of molten zone at infinity solidifies differently and can be described mathematically as directional crystallization. A mathematical tool devised for second pass of zone refining can be tried to be used for derivation of functions of more complex models that would describe impurity distribution in more realistic way compared to simplified approach. Such models could include non-constant distribution coefficient and/or shrinking or widening molten zone over a length of ingot.

Published: March 2021

Objectives: Parental involvement in sports activities of school-going children is considered as an important factor towards their sports participation. So, the purpose of this study was to analyze the impact of parental motivation, parental perception, and parental financial support on the participation of students in sports.
Methods: A sample of 387 male students were selected through simple random sampling. Descriptive statistics, correlation, and regression analysis techniques were applied.
Results: The Cronbach's alpha reliability for overall scales was 0.90. The average age of the participants was 15.46 years. The parental motivation level was close to moderate, the parental perception level was below moderate, the parental financial support level was above moderate and the sports participation level was equal to moderate level. All variables were positively and significantly (p<0.01) correlated with each other.
Conclusion: Parental financial support had a positive and significant effect on students’ sports participation. Therefore, parents and school management should provide sports equipment, coaching facilities, and a safe environment to improve the students' sports activities for their sound health and mind.
Be Mindful of Your Discomfort: An Approach to Contextualized Learning
Authors: Bheekie Angeni , van Huyssteen Mea 
Published: March 2021

Service-learning creates a space for contextualized learning whereby students connect classroom concepts to real-world practices relative to their own frame of reference. These experiences occur within a societal status quo rooted within historical and social inequalities. Affective responses to encounters with inequalities are not routinely addressed within the learning outcomes of formal curricula. Thus, the pedagogy of discomfort calls for an awareness and a critical self-examination among educators and students of how their passive acceptance or non-acceptance of apparent social injustices has been shaped by the status quo. By incorporating affective learning into the reflective process, we realized that contradictions in South African society permeate students’ experiences in ways that are indicative of the status quo. Increased recognition of the potential of affective learning to address social injustices in higher education could enable efforts toward social transformation.
Community Partnerships and Impacts
Authors: Bargerstock Burton A , Bloomgarden Alan 
Published: March 2021

Achieving reciprocity and mutual benefit from service-learning and community engagement collaborations between higher education institutions and their communities is essential to making such ventures impactful, responsible, and sustainable. Framing these collaborations as “partnerships” helps those in the field hold themselves and their colleagues (on and off campus) accountable to such standards of practice as centering community voice in agenda setting, assessing mutually beneficial opportunities and needs, and evaluating outcomes important to all stakeholders. In practice, building partnerships that integrate the research and learning aims of higher education into community-driven agendas for addressing urgent societal issues calls for deep and lasting attention to relationship-building among students, faculty, administrators, and community partners. The articles in this section of IJRSLCE focus intensely on impacts and outcomes from sustained engagement in the design and articulation of reported collaborations.
NATIONAL CORPUS OF RUSSIAN LANGEUAGE ABROAD: APPLICATION SITUATION OF НКРЯ IN CHINESE COLLEGES AND UNIVERSITIES AND EVALUATION OF ITS FUNCTION
Authors: Сунь М. 
Published: March 2021

НКРЯ как масштабный, аннотированный и открытый онлайн-корпус языковых данных обладает большим потенциалом применения не только в России, но и во многих других странах. В данной статье рассматривается использование НКРЯ в исследовании по русскому языку и в преподавании РКИ в вузах Китая. Анализ соответствующей литературы и результатов опроса показал, что в вузах Китая НКРЯ пользуется более широкой популярностью, чем другие корпусы русского языка. Респонденты дают НКРЯ хорошую оценку. В последние годы все больше преподавателей русского языка начинают использовать НКРЯ. При проведении научных исследований применение НКРЯ демонстрирует тенденцию к постепенному углублению, но его вспомогательная форма в обучении все еще является относительно однородной, преимущества НКРЯ до сих пор в полной мере не реализуются.
As a huge, annotated and open online language database, НКРЯ has great application potential in Russia and many other countries. This paper analyzes the application of НКРЯ in Russian studies and Russian teaching in Chinese colleges and universities. Through the analysis of relevant literature and questionnaire results, the research shows that in Chinese colleges and universities, the application of НКРЯ is more popular than other Russian corpora. The teachers who participated in the questionnaire gave a good evaluation. In recent years, more and more teachers have begun to use НКРЯ. In scientific research, the application of НКРЯ is getting deeper, but the form of НКРЯ assisted instruction is relatively simple. Besides, the advantages of НКРЯ have not been brought into full play in related fields.

Relativistic Reflection in NGC 4151
Authors: Szanecki Michał , Niedźwiecki Andrzej , Zdziarski Andrzej A. 
Published: March 2021

Abstract
We investigate the X-ray spectrum of the Seyfert galaxy NGC 4151 using the simultaneous Suzaku/NuSTAR observation and flux-resolved INTEGRAL spectra supplemented by Suzaku and XMM observations. Our best spectral solution indicates that the narrow Fe Kα line is produced in Compton-thin matter at a distance of several hundred gravitational radii. In such a model, we find a weak but significant relativistic reflection from a disk truncated at about 10 gravitational radii when the source is in bright X-ray states. We do not find evidence either for or against the presence of relativistic reflection in the dim X-ray state. We also rule out models with X-ray emission dominated by a source located very close to the black hole horizon, which was proposed in previous works implementing the lamppost geometry for this source. We point out that accurate computation of the thermal Comptonization spectrum and its distortion by strong gravity is crucial in applications of the lamppost geometry to the NuSTAR data.

Abstract
Using radio observations with the Green Bank Telescope, evidence has now been found for a second five-membered ring in the dense cloud Taurus Molecular Cloud-1 (TMC-1). Based on additional observations of an ongoing, large-scale, high-sensitivity spectral line survey (GOTHAM) at centimeter wavelengths toward this source, we have used a combination of spectral stacking, Markov Chain Monte Carlo (MCMC), and matched filtering techniques to detect 2-cyanocyclopentadiene, a low-lying isomer of 1-cyanocyclopentadiene, which was recently discovered there by the same methods. The new observational data also yield a considerably improved detection significance for the more stable isomer and evidence for several individual transitions between 23–32 GHz. Through our MCMC analysis, we derive cospatial, total column densities of 8.3 × 1011 and 1.9 × 1011 cm−2 for 1- and 2-cyanocyclopentadiene, respectively, corresponding to a ratio of ∼4.4 favoring the former. The derived abundance ratios point toward a common formation pathway—most likely being cyanation of cyclopentadiene by analogy to benzonitrile.
Faire l’expérience d’une démarche d’analyse de pratique autogérée : le pari de la confiance
Authors: Doublet Marie-Hélène 
Published: March 2021

Les métiers de l’accompagnement et du conseil en évolution professionnelle sont aux prises avec un ensemble de paradoxes rendant l’exercice du métier parfois impossible. Pour faire face aux différentes pressions, entre la commande sociale et les demandes individuelles, nous faisons appel à des démarches d’exploration de l’expérience des professionnels par eux-mêmes et pour eux-mêmes. Cet article propose de décrire les circonstances amenant à la conception d’un dispositif qui transfère aux membres du collectif de métier les moyens de partager leur pratique à partir de leur expérience, d’en expliciter les principes et les difficultés. Dans un deuxième temps, à partir d’une recherche-action-formation menée auprès des conseillers en évolution professionnelles qui accompagnent les actifs en emploi, nous présenterons la mise en place de ce dispositif autogéré, permanent et sans intervenant extérieur. Quelles précautions pour créer un espace de coopération nécessaire à l’expression de l’expérience singulière, et faciliter sa formalisation en règles et gestes de métier ? Quelles conditions pour permettre une mise en confrontation respectueuse, source de développement d’acquis individuels et collectifs, pour initier des modes d’interaction avec les équipes de gouvernance, afin de peser efficacement dans les instances et les débats où la fonction conseil se décide ?

ABSTRACTThe COVID-19 pandemic has caused serious health and social concerns worldwide. Although the primary target of SARS-CoV-2 is the respiratory tract, SARS-CoV-2 infection also causes extrapulmonary symptoms. Previous articles have reported ischemic colitis in COVID-19 patients; however, information regarding its clinical manifestations and pathophysiology is limited. In this case report, we present two cases of ischemic enterocolitis in COVID-19 patients and review past case reports. Our literature review has shown that computed tomography rather than endoscopy was used for the diagnosis, and any region of the intestine was affected. Because the elevation of the D-dimer, which suggested a hypercoagulable state, was reported in most cases, we assumed that thrombosis at any level in the artery and vein was involved in the pathophysiology of COVID-19–associated enterocolitis. SARS-CoV-2–induced endotheliitis can cause both coarctation of the vessels and thrombosis; therefore, both patterns of ischemic colitis, occlusive and nonocclusive, may be involved in COVID-19–associated enterocolitis.

ABSTRACTOf the 107 million COVID-19 cases worldwide, less than 2 million have been reported in African countries. The aim of this study was to evaluate the seroprevalence of SARS-CoV-2 infection in Ivory Coast mine workers. From July 15 to October 13, 2020, a voluntary serological test campaign was conducted in 3 sites: two gold mines, and the headquarters in Abidjan. Rapid tests to detect IgG and IgM on capillary blood were performed. To identify independent sociodemographic characteristics associated with a higher SARS-CoV-2 seroprevalence rate, a multivariate logistic regression analysis was performed. A total of 1,687 subjects were tested; 91% were male (n = 1,536), and the mean age was 37 years. The overall seroprevalence was 25.1% (n = 422), ranging between 13.6% (11.2–16.1%), 34.4% (31.1–37.7%), and 34.7% (26.2–43.2%) in mine A, in mine B, and in Abidjan, respectively. Among the 422 seropositive subjects, 74 reported mild symptoms in the three previous months and one was hospitalized for severe COVID-19 infection. SARS-CoV-2 seroprevalence is high in both gold miners and administrative staff working in Ivory Coast. The burden of infection in West Africa has probably been underestimated till now.

Published: March 2021

This paper considers the multicast transmit beamforming and receive power splitting problem for sum transmit power minimization for a simultaneous wireless information and power transfer (SWIPT) system subject to signal-to-interference-plus-noise ratio (SINR), and energy harvesting constraints at the receiver. In particular, we consider the case of perfect and imperfect channel state information (CSI) at the base station. Using semidefinite relaxation (SDR) technique, we obtain solution to the problem with imperfect channel state information of the self-interfering channels.
Keywords: Simultaneous wireless information and power transfer, channel state information, Energy harvesting, semidefinite relaxation.
