Demodulation of a weak fiber Bragg grating array using a fiber delay line
Authors: Ding Peng , Liu Wen , Gu Hongcan , Wang Yunyun , Wu Jing , Huang Junbin , Tang Jinsong
Published: February 2020

We demonstrate the use of a fiber delay line (FDL) to demodulate a weak fiber Bragg grating (WFBG) array. The FDL is composed of a fiber-ring cavity, by which the delay time is matched with the interval length of the adjacent WFBGs. Two pulses reflected by the former WFBG with delay and a pulse reflected by the rear WFBG without delay overlap and interfere. The emitted sounds can be given by the interference signals of a 5-WFBG array with the FDL. Using the FDL, it is demonstrated that the simple structure can be used to demodulate the WFBG array.

The diode laser bar was beam shaped with a tilted cylindrical lens array to twist the slow axis of individual emitters by 90 deg, and then the slow axis was collimated with a single cylindrical lens. From the simulation, 20 laser diode bars with the same wavelength formed a diode laser optical stack with an output power of more than 3.5 kW, a beam spot of

Then, three laser diode optical stacks with different wavelengths were wavelength-multiplexed to obtain an output power of more than 10 kW. Finally, the diode laser optical stack was transformed by simple cylindrical lenses to form a line shape spot with a working distance longer than 250 mm. Our diode laser design is much simpler than previous devices with similar output power and can find various applications such as high-speed laser cladding.

A temporal resolution of 42 ps and a dark count rate of 500 Hz were achieved, limited by the SPAD and ambient light leakage. It allowed for detection of two targets separated by only a few millimeters. This technique is easily extendable to longer wavelengths, limited primarily by the nonlinear crystal transparency.
Theoretical analysis of a white-light LED array based on a GaN nanorod structure
Authors: Ji Jincai , Zhang Guangna , Yang Shaobo , Feng Xiaolu , Zhang Xu , Yang C. C.
Published: February 2020

Based on the experimentally demonstrated In content distribution in the InGaN/GaN quantum wells on a two-section GaN nanorod (NR) sidewall, a white-light light-emitting diode (LED) without phosphor is designed and simulated. Following the dependencies of the In diffusion length and incorporation ratio on NR geometric variables of a theoretical model, the height, radius, and tapering section geometry of the GaN NR are designed for controlling the relative intensities of a blue and a yellow emission component to mix into white light. The higher-In upper section of the NR is first excited to emit a relatively stronger yellow component when injection current is low. As the injection current increases, more current spreads into the lower-In lower section, eventually leading to a stronger blue emission component. The proposed NR LED structure provides an alternative solution for phosphor-free white-light generation.
Label-free characterization of different kinds of cells using optoelectrokinetic-based microfluidics
Authors: Liang Wenfeng , Yang Xieliu , Wang Junhai , Wang Yuechao , Zhang Hemin , Yang Wenguang , Liu Lianqing
Published: February 2020

We report a novel, to the best of our knowledge, method to rapidly characterize different kinds of cells and drug-treated cancer cells using a label-free biomarker of self-rotation in an optoelectrokinetics (OEK)-based microfluidic platform. OEK incorporates optics and electrokinetics into microfluidics, thereby offering a contact-free, label-free, and rapid approach to the cellular manipulation community. Self-rotational behaviors of four different kinds of cells were experimentally investigated by the frequency-sweeping of an AC bias potential in an optically induced nonuniform and irrotational electric field. The results revealed that these kinds of cells displayed a Gaussian distribution versus the AC frequency as well as different self-rotational speeds under the same conditions. Furthermore, the peak self-rotational speed varied from one kind of cell to another, with that of cancer cells higher than that of normal cells. In addition, MCF-7 cells treated by various concentrations of drug showed remarkably different self-rotational speeds. This finding suggests a high potential of developing a new label-free biomarker to rapidly distinguish different kinds of cancer cells and quantitatively monitor the response of cancer patients to various treatments.

Effect of Different Proteinase K Digest Protocols and Deparaffinization Methods on Yield and Integrity of DNA Extracted From Formalin-fixed, Paraffin-embedded Tissue
Authors: Frazer Zoe , Yoo Changyoung , Sroya Manveer , Bellora Camille , DeWitt Brian L. , Sanchez Ignacio , Thomas Geraldine A. , Mathieson William
Published: February 2020

DNA extracted from formalin-fixed, paraffin-embedded tissue sections is often inadequate for sequencing, due to poor yield or degradation. We optimized the proteinase K digest by testing increased volume of enzyme and increased digest length from the manufacturer’s protocol using 54 biospecimens, performing the digest in centrifuge tubes. Doubling the quantity of proteinase K resulted in a median increase in yield of 96%. Applying the optimized proteinase K protocol to sections deparaffinized on microscope slides generated a further increase in yield of 41%, but only at >50,000 epithelial tumor cells/section. DNA yield now correlated with (χ2 = 0.84) and could be predicted from the epithelial tumor cell number. DNA integrity was assayed using end point multiplex PCR (amplicons of 100–400 bp visualized on a gel), quantitative PCR (qPCR; Illumina FFPE QC Assay), and nanoelectrophoresis (DNA Integrity Numbers [DINs]). Generally, increases in yield were accompanied by increases in integrity, but sometimes qPCR and DIN results were conflicting. Amplicons of 400 bp were almost universally obtained. The process of optimization enabled us to reduce the percentage of samples that failed published quality control thresholds for determining amenability to whole genome sequencing from 33% to 7%.
CONSUMER SURVEY & LIFE CYCLE ASSESSMENT (LCA) OF PHARMACEUTICAL WASTE DISPOSAL PRACTICES IN THE UK
Authors: Mohamed Yunus Siti Syuhaida
Published: February 2020

Unused or expired medicines from the hospital and household waste can ultimately end up in landfills or be released to the wastewater system. There is, therefore the potential for active pharmaceutical ingredients (APIs), from a range of medicinal products, to be present in landfill leachate and sewage effluents. In this project, a household survey was performed to understand the typical waste generation patterns for medicines and disposal routes. The results from the household survey showed; 206 respondents from Yorkshire (56.3%), and 43.7% from Berkshire, Oxfordshire, Greater London and other regions. From the survey as well, the results have been divided into two categories, over-the-counter (OTC) and prescription medicines; disposal options order for OTC medicines from 53.2% of disposed of percentage are, throw into rubbish (28.6%), take-back to pharmacies (16.1%), toilet disposal (1.9%), sink disposal (1.6%) and others such as disposal as per instructed on medicines packets (5%); meanwhile, for the disposal options order from 21.2% of disposed of percentage, take-back to pharmacies (12.1%), throw into rubbish (5.4%), toilet disposal (0.3%), sink disposal (0.3%) others such as disposal as per instructed on medicines packet (3.1%). It shows that disposal into rubbish (34%) has been identified as the most common disposal methods by the respondents in the UK and these pharmaceuticals waste will ultimately end up in the landfills. Life cycle assessment (LCA) was then used to compare the environmental emissions from different pharmaceutical waste disposal options. The LCA work is ongoing but is exploring the following practices: disposal to the toilet or sink (wastewater treatment); the use of take-schemes (incinerations); disposal of into rubbish (landfills); and new in situ treatment approaches (e.g. PyroPure). Conclusions from the analysis will be presented.

Published: February 2020

A 37-year-old man underwent screening examinations, and a pale-colored submucosal tumor was detected on gastric cardia. Endosonography showed a 15-mm cyst with hypoechoic nodules in the muscularis propria, and endoscopic ultrasound-guided fine-needle aspiration obtained mucinous fluid with atypical spindle cells positive for c-kit, indicating a gastrointestinal stromal tumor. Surgical resection was recommended, but he initially agreed to surveillance. After becoming larger for 8 years, partial gastrectomy was performed for the 22 × 22 × 15-mm capsulized lesion. Surprisingly, its histology was gastric duplication cyst without gastrointestinal stromal tumor. Gastric duplication cyst is a rare entity with the possibility of malignant complications, but careful assessment of endoscopic ultrasound-guided fine-needle aspiration might also be required.

Authors: Hafizuddin H , Karja Ni Wayan Kurniani , Praharani Lisa , Setiadi Mohamad Agus
Published: February 2020

Reproduction is an important factor that requires attention to increase livestock production. The application of artificial insemination (AI) technology has been developed rapidly in the world, so that availability of fertile superior male is a determinant factor of successful AI. Several recent studies have been aimed to discover male fertility biomarkers, by intense research on fertility-assosiated proteins contained in seminal plasma. This paper describes the role of adiponectin as a candidate of male biomarker fertility. Adiponectin has a positive effect on spermatozoa functionality and steroidogenesis. This has been proven by several studies that found its expression in Sertoli cells and Leydig cells in the reproductive tract. Based on the specific role on spermatozoa functionality and steroidogenesis in supporting male fertility parameter, it is strongly suggested that adiponectin is an excellent candidate biomarker for male fertility.
posição das orações concessivas introduzidas por 'aunque' no espanhol falado peninsular
Authors: Parra de Araujo Beatriz Goaveia Garcia , Gasparini Bastos Sandra Denise
Published: February 2020

Este trabalho analisa a posição das orações concessivas introduzidas por aunque no espanhol peninsular falado, à luz do modelo teórico da Gramática Discursivo-Funcional (HENGEVELD; MACKENZIE, 2008), que prevê quatro níveis de análise hierarquicamente organizados: Interpessoal, Representacional, Morfossintático e Fonológico. O ponto de partida para a análise da posição toma como critérios a pressuposição de conteúdo, diretamente relacionada à informatividade das orações, e a (in)dependência da oração concessiva com relação à principal. Os dados selecionados consistem em entrevistas pertencentes ao Projeto PRESEEA, mais especificamente amostras de fala das cidades espanholas de Alcalá de Henares, Granada, Madri e Valência. A análise revela que as orações concessivas que atuam nas camadas da Ilocução e do Conteúdo Proposicional, pertencentes, respectivamente, ao Nível Interpessoal e ao Nível Representacional, ocorrem, preferencialmente, antes da oração principal, por exercerem o papel de modificadores. Apresentam, assim, uma maior dependência semântico-sintática com relação à oração principal e trazem, predominantemente, conteúdos pressupostos. Já as concessivas que atuam nas camadas do Movimento e do Ato Discursivo, unidades do Nível Interpessoal, ocorrem sempre após a oração principal. Tais orações inserem comentários ou digressões relativos à informação anteriormente expressa e trazem, predominantemente, conteúdos não pressupostos. A pesquisa comprova que a posição, enquanto critério do Nível Morfossintático, é motivada pelas representações advindas dos níveis hierarquicamente superiores (Interpessoal e Representacional).

características sistemáticas de recursos multimodais mobilizados por uma criança com TEA em turnos de fala corporificados
Authors: Santiago Douglas Vidal
Published: February 2020

Este artigo visa a analisar os recursos multimodais (fala, gesto, objetos, movimentos corporais) mobilizados por Luiza, pseudônimo de uma criança com diagnóstico de Transtorno do Espectro do Autismo (TEA), e por seus interlocutores familiares durante o processo de construção da atenção conjunta em uma interação cotidiana em ambiente não-institucional. Para tanto, focamos em abordagens que enfatizam os aspectos multimodais da linguagem, destacando a articulação fina entre as produções verbais e gestuais mobilizadas por esse sujeito com TEA como formas linguísticas que produzem uma complexidade estrutural semântica e pragmática que pode contribuir para os estudos sobre as relações entre gestos e gramática, em busca de uma Gestalt (padrão) Multimodal (gesto/postura + fala) Complexa no repertório comunicativo dessa criança. Os achados da análise empreendida sugerem que embora possua algumas restrições do ponto de vista dos recursos verbais, Luiza os mobiliza de modo articulado a recursos não-verbais para construir e para participar da situação interativo-comunicacional. Destarte, a investigação multimodal possibilitou dar visibilidade a uma gama de recursos linguísticos e gestuais empregados por essa criança.
Choque valorativo e provocação em tiras da Mafalda
Authors: Corrêa Erick Kader Callegaro , Schmidt Ana Paula Carvalho
Published: February 2020

O presente trabalho é resultado de estudos realizados sobre o Sistema de avaliatividade de Martin e White (2005) e sua aplicação a estudos de gênero. Após seleção do gênero tira em quadrinhos, foram escolhidos exemplares de Mafalda, do autor argentino Quino. A escolha foi motivada pelas características dos textos: escassez lexical e mescla de linguagem verbal e não verbal (MENDONÇA, 2005), que contribuem para a realização do sistema avaliativo. O objetivo deste trabalho é identificar como as avaliações são realizadas, utilizando-se o aporte do Sistema da avaliatividade (MARTIN; WHITE, 2005). Para isso, foram escolhidas cinco tiras, publicadas em 2012. Primeiramente, os textos foram analisados, de acordo com os recursos léxico-gramaticais e algumas expressões idiossincráticas de cada personagem nos quais são evidenciadas características valorativas. A seguir, procurou-se delinear outras formas de avaliação, se inscritas ou evocadas. Após a análise, percebeu-se um padrão semântico-discursivo de avaliações, tanto inscritas como evocadas, que semanticamente, carregam consigo valores e crenças opostas que entram em conflito e causam humor. Como num efeito dominó, as avaliações inscritas dão origem a avaliações provocadas, nas quais o autor parece direcionar seu leitor a uma avaliação final do fenômeno cotidiano em jogo.
Uma análise tipológica preliminar do sistema de classificadores em línguas Arawák
Authors: Miranda Camille Cardoso
Published: February 2020

O presente artigo objetiva descrever preliminarmente o sistema de classificadores em 15 línguas que compõem a família linguística Arawák (Arawák): Achaguá, Ashéninka Perené, Baniwa de Içana, Baure, Garifuna, Mehináku, Nanti, Palikur, Paresi, Resígaro, Tariana, Wapixana, Warekena, Waujá e Yawalapiti. Os classificadores são geralmente definidos como morfemas que ocorrem em estruturas da superfície que denotam algumas características semânticas associadas aos seus referentes. Os tipos de classificadores descritos nesse estudo são os numerais, nominais, genitivos, verbais, locativos e com adjetivos. Como resultado, verificamos que os classificadores de número é o tipo mais comum entre essas línguas, enquanto o locativo e os adjetivos são os mais raros. Desse modo, estabelecemos um estudo tipológico preliminar para verificar os possíveis padrões do sistema de classificadores das 15 línguas que compõem a família Arawák.
Práticas de feedback em um curso de formação de professores de língua inglesa a distância
Authors: Ribas Fernanda Costa , Manzan Perine Cristiane
Published: February 2020

Considerando o crescimento dos cursos de licenciatura na modalidade EaD no contexto brasileiro, este artigo tem por objetivo analisar os processos de feedback que acontecem em um curso de formação de professores de língua inglesa na modalidade EaD de uma universidade federal mineira. O feedback pode ser definido como comentários em forma de opinião sobre as reações de algo, com o objetivo de prover informações úteis para futuras decisões e melhorias (ENCARTA, 2007). Acredita-se que o feedback exerce um papel fundamental na EaD, uma vez que dá ao aluno uma perspectiva de seu desenvolvimento e progresso na aprendizagem da língua; é uma ferramenta importante para o desenvolvimento da confiança e autonomia dos alunos (GARRIDO, 2005), além de influenciar a motivação e a capacidade de aprendizagem (HURD, 2006). Neste artigo, serão analisadas as práticas de feedback de tutores em duas atividades de língua inglesa postadas em fóruns de discussão virtual. Os meios de fornecer feedback adotados pelos tutores, bem como as abordagens adotadas (comentários e correções) serão apresentados e discutidos. Espera-se que expandir o entendimento da relação entre feedback e aprendizagem encoraje tomadas de decisão mais informadas no que concerne às especificidades que compõem a formação de professores de línguas na EaD, em seus desafios de promover a reflexão e formar profissionais com proficiência em língua inglesa.
argumentos quase lógicos e os lugares da argumentação no gênero propaganda oral radiofônica
Authors: Da Rocha Max Silva , Oliveira Santos Maria Francisca
Published: February 2020

Por meio dos estudos retóricos, é possível entender o emprego das técnicas argumentativas utilizadas por oradores para tentar convencer e persuadir determinado auditório social. Diante desse entendimento, este trabalho tem como principal objetivo analisar os argumentos quase lógicos e os lugares da argumentação presentes no gênero propaganda oral radiofônica veiculado na rádio alagoana. Desse modo, o trabalho entende a Retórica como um mecanismo discursivo capaz de verificar como se dá a persuasão nos mais diversos discursos. A partir desse posicionamento, este estudo filia-se, metodologicamente, à perspectiva qualitativa, pois dá ênfase ao processo dos dados e não ao produto final. O olhar descritivo-interpretativista da abordagem qualitativa permite ao pesquisador observar os dados processualmente. Por isso, embasa-se nos referenciais teóricos de Abreu (2009), Aristóteles (2011), Ferreira (2015), Meyer (2007), Perelman e Olbrechts-Tyteca (2014), Santos (2011; 2018), entre outros. O foco da análise é o espaço radiofônico, com destaque para a propaganda oral, que teve como suporte de veiculação uma emissora de rádio do agreste alagoano. Os resultados indicam que os argumentos quase lógicos com a junção dos lugares da argumentação foram utilizados de maneira decisiva pelos oradores, para o acontecimento do gênero propaganda oral radiofônica no rádio alagoano.

ECHO CHAMBERS DI DUNIA MAYA: TANTANGAN BARU KOMUNIKASI ANTAR UMAT BERAGAMA
Authors: Yahya Yuangga Kurnia , Mahmudah Umi
Published: February 2020

This article tries to see a phenomenon called Echo Chambers through the perspective of Stella Ting-Toomey’s Intercultural Communication Theory. This study shows that the development of social media was also followed by the shadow of Echo Chambers. The tendency to isolate oneself and associate with those who understand one another will create separate spaces between one religion and another. As a result, communication which is an effort to eliminate the polarization of the differences between "Us" and "The Others" is precisely the way to form an exclusivism in cyberspace. Among the efforts to anticipate the emergence of a gap is to create melting-pot spaces in the real world. Counter narrative also needs to be built to open these exclusive barriers. Muslim scholars sought to introduce the importance of communication in achieving the harmony in community. Some Ulama have also explained the role and function of communication in achieving the goals of the ummah, as well as trying to provide an Islamic perspective regarding communication behavior. More important, is to create a person who is a wise, open user of social media and uses epoche in looking at the world outside.

Published: February 2020

In international relations, especially relations between countries, it will always have the potential to have cooperation, agreements, even disputes. In general, all countries in the world make relations between countries as a manifestation of wanting peace because every country definitely needs other countries to be able to meet their country's needs. The current concept of Diplomacy is something that international actors are currently doing to establish cooperation with a country. However, when the path of diplomacy cannot be used, using hard power in the form of war is an instinctive thing that is done by a country to achieve its interests. Islam has its own perspective and guidance in studying relations between countries, through peace, the concept of diplomacy and the circumstances in which war is permitted.Keywords: Peace-Diplomacy-War, Islamic Perspective, International Relations.

Published: February 2020

The aim of the study was to assess the selected physical characteristics of the briquettes of English ryegrass waste biomass and its mixtures with waste components from the agri-food industry: pea husks and oat middlings. The raw materials used for the tests are characterized by high calorific value and low ash content. Among the tested raw materials, the most favorable values were recorded for oat middlings in this respect. The produced briquettes were characterized by high volumetric density and very diverse mechanical durability. At the same time, the results of the tests on the mechanical durability of briquettes indicated that the use of components of ryegrass mixtures selected for testing brought unsatisfactory results, as compared to other analyzed physical and energy features.

The paper presents a study on the control of the canned fish seaming with the so-called double seam and statistical analysis of correctness of seaming. The use of standard control charts enabled observation and intervention in case irrelevant parameters occur to keep the stability of the process. Based on the analysis made in Statistica program, a moment could have been captured when a machine had to be regulated in case the value of parameters of the double seam decreased and it had to be concluded unanimously when the most important seaming tools (rolls) should be replaced. A problem that had been solved consists mainly in ensuring the stability of the process during constant monitoring of the seaming process of the canned food.

For seed production of sugar and fodder beet, the creation of machines and working bodies for planting root crops on testes and pollinators is of current importance. It was found out that the seed-and-water production was spreading with the use of “schteklings” [sugar beet roots]. In the countries with minus temperatures between the vegetation seasons it is necessary to dig out beets and plant them again at the beginning of the vegetation season. Advantages and disadvantages of machines and apparatus for disembarking the schteklings were determined. Under the conditions of applicability, we chose a design scheme and a type of landing gear. With the use of mathematical expressions and standards for the labor intensity of the operator of the above machine, the optimal parameters of its planting apparatus were determined. It was determined that the work of the operator of the schteklings planting machine’s stem will meet the safety standards for the intensity of labor if the planting unit of this machine is a rotor-type. It should be equipped with planting cones and a charging device, a conveyor type. The number of holders of landing cones should be 6-8 pieces, and the radius of the rotor is within the range of 0.344 ... 0.382 m. Such a scheme, type and parameters of the landing gear will allow operators to work at the speed of the planter of up to 1.2 m·s−1.

Published: February 2020

The modern agriculture model is a model based on the principles of sustainable development, i.e. protecting the environment and the cultural landscape on the one hand, and on the other, ensuring adequate income for residents. It is based on three orders: ecological, social and economic. This paper attempts to use cluster analysis to assess the economic and ecological sustainability of organic farms. It also indicates the factors that statistically influenced the assessment of a farm as sustainable, or not. The first part of the work is dedicated to the characteristics of the problem and the methodology of research and analysis. The second part contains the results of the research and discusses them.
The generalized complexity of linear Boolean functions
Authors: Redkin Nikolay P.
Published: February 2020

We study generalized (in terms of bases) complexity of implementation of linear Boolean functions by Boolean circuits in arbitrary functionally complete bases; the complexity of a circuit is defined as the number of gates. Let L*(n) be the minimal number of gates sufficient for implementation of an arbitrary linear Boolean function of n variables in an arbitrary functionally complete basis. We show that L*(0) = L*(1) = 3 and L*(n) = 7(n – 1) for any natural n ≥ 2.
Well-posedness of backward stochastic partial differential equations with Lyapunov condition
Authors: Liu Wei , Zhu Rongchan
Published: February 2020

In this paper we show the existence and uniqueness of strong solutions for a large class of backward SPDEs, where the coefficients satisfy a specific type Lyapunov condition instead of the classical coercivity condition. Moreover, based on the generalized variational framework, we also use the local monotonicity condition
to replace the standard monotonicity condition, which is applicable to various quasilinear and semilinear BSPDE models.
European beech log and lumber grading in wet and dry conditions using longitudinal vibration
Authors: Rais Andreas , Pretzsch Hans , van de Kuilen Jan-Willem G.
Published: February 2020

In Central Europe, European beech (Fagus sylvatica L.) is the most frequently occurring hardwood species. An efficient grading method has the potential to promote its utilisation as construction material. Wood density, eigenfrequency and length were measured in 99 European beech logs for calculating the dynamic modulus of elasticity (MOEdyn
) obtained by longitudinal vibration (resonance). In addition, the log taper was measured. Of those logs, 867 boards were cut using a bandsaw. The MOEdyn
in green condition was determined on 505 of the boards and the MOEdyn
in dry conditions was determined on all of them. The r2 value between the MOEdyn
of a log and the mean of MOEdyn
of its boards was 0.72 in the wet condition. The MOEdyn,12%
of boards significantly increased by 88 N mm−2 for each centimetre away from the pith. The negative effect of log taper on MOEdyn
of boards was barely significant (P-value = 0.050). The MOEdyn,12%
was highly dependent on the MOEdyn,wet
(r2 = 0.83) and was 17% higher than the MOEdyn,wet
. The mechanical properties of European beech timber exceed those of European softwood species. However, the relationships regarding MOEdyn
between different grading levels in the processing chain appear to be similar to those of softwoods.
Is it really just a joke? Gender differences in perceptions of sexist humor
Authors: Lawless Tiffany J. , O’Dea Conor J. , Miller Stuart S. , Saucier Donald A.
Published: February 2020

Benign violation theory suggests humor mocking normative values is funny if the humor is non-threatening. Research suggests sexism toward women (versus men) is particularly threatening due to inequalities in social power. In Study 1, we examined whether men and women differ in how amused and offended they were by sexist humor. We predicted men would perceive sexist humor as more funny and less offensive than women would. In Study 2, we examined whether perceptions of threat were related to perceptions of sexist jokes. We predicted women would perceive more threat than men from sexist humor, which would lead to lower amusement and greater perceived offensiveness. Across both studies, jokes targeting women were perceived to be less funny, more offensive, and more sexist than jokes targeting men. Additionally, greater perceptions of threat were related to greater perceptions of jokes as offensive and sexist. However, women were not more threatened than men by sexist jokes. While these findings were not entirely consistent with our hypotheses, our findings suggest disparagement humor targeting lower-status groups is perceived more negatively than disparagement humor targeting higher-status groups and these perceptions may be inextricably rooted in threat posed to lower-status groups.
Re-imaging Clinical Education: The Interdependence of the Self-Regulated Clinical Teacher and Nursing Student
Authors: Filice Sandra , Tregunno Deborah , Edge Dana , Egan Rylan
Published: February 2020

The interdependence of student learning strategies and teacher’s pedagogical practices is critical to clinical practice learning. While research demonstrates that formative assessment feedback is important for student learning, clinical teachers do not necessarily have the competencies to provide effective feedback to support students’ self-regulated learning (SRL). An examination of clinical education through SRL lenses articulates two roles for clinical teachers in nursing clinical education: self-regulated learner and self-regulated teacher. Teachers as self-regulated learners are practice-content experts and must also learn how to explicitly help students become self-regulated learners. The latter is the self-regulated teacher role, and a self-regulated teacher is an effective clinical teacher. Minimal research addresses the ways in which clinical teachers’ effectiveness could be improved if they took on a self-regulated teacher role. A model of SRL and teaching in clinical practice education is presented and its potential to enhance clinical teacher effectiveness and student SRL articulated.
Linear least squares method in nonlinear parametric inverse problems
Authors: Frumin Leonid L.
Published: February 2020

A generalization of the linear least squares method to a
wide class of parametric nonlinear inverse problems is presented.
The approach is based on the consideration of the operator
equations, with the selected function of parameters as the
solution. The generalization is based on the two mandatory
conditions: the operator equations are linear for the estimated
parameters and the operators have discrete approximations. Not
requiring use of iterations, this approach is well suited for
hardware implementation and also for constructing the first
approximation for the nonlinear least squares method. The examples of
parametric problems, including the problem of estimation of parameters
of some higher transcendental functions, are presented.

Published: February 2020

Recently, Nair and Roy (2017) considered a linear regularization method for a parameter identification problem in an elliptic PDE.
In this paper, we consider similar procedure for identifying the diffusion coefficient in the heat equation, modifying the Sobolev spaces involved appropriately.
We derive error estimates under appropriate conditions and also consider the finite-dimensional realization of the method, which is essential for practical application.
In the analysis of finite-dimensional realization, we give a procedure to obtain finite-dimensional subspaces of an infinite-dimensional Hilbert space

Also, we analyze the parameter choice strategy and obtain an a posteriori parameter which is order optimal.
Evaluation of Atmospheric Detrimental Effects on Free Space Optical Communication System for Delhi Weather
Authors: Srivastava Disha , Kaur Gurjit , Singh Garima , Singh Prabhjot
Published: February 2020

Free Space Optical (FSO) communication systems are gaining popularity due to its tremendous speed, advanced capacity, cost effectiveness, secure and easy to deploy wireless networks. This technology has proven an effective choice for last mile applications and hard to reach areas where deployment of optical fibre links is not feasible. But FSO link is highly weather dependent and as signal passes through the atmospheric channel, the main impairments are the atmospheric turbulence, which induce fading and deteriorate the system performance. Delhi has a great potential for FSO communication because of its clear skies. Since there is no analysis for weather condition found in Delhi, this work provides analysis of typical Delhi weather condition ranging from heavy to light rain, fog and clear sky. The performance of FSO link is analysed in terms of attenuation and link length margin under different weather condition. The results are concluded to identify which atmospheric condition influences more on FSO link performance.
The effect of placental elasticity on intraoperative bleeding in pregnant women with previous cesarean section
Authors: Tolunay Harun Egemen , Eroğlu Hasan , Kaya Onur , Şahin Dilek , Yücel Aykan
Published: February 2020

Background

We aimed to evaluate the efficiency of placental elasticity in predicting the amount of intraoperative bleeding via real-time tissue elastography technique.

Methods

Pregnant women in the third trimester of pregnancy who had planned delivery via cesarean section due to the recurrent cesareans were enrolled in the research (n = 78). Elastographic measurements of placental tissues of all cases were carried out by real-time elastographic ultrasonography. It is a tissue elastography software (Esaote MyLabSeven) that uses a 8-1-MHz multifrequency AC2541 Probe.

Results

A significant relationship was found between placental elasticity and intraoperative bleeding. There was a significant correlation between alterations in the preoperative and postoperative hemoglobin (Hb) and hematocrit (Hct) levels and placental strain ratio (SR) (P < 0.001, r: 0.831; P < 0.001, r: 0.733, respectively).

Conclusion

These findings may reflect an alteration at the tissue elasticity level. We hope that the use of real-time elastographic ultrasonography technique may give an idea about the amount of bleeding during the cesarean section.
