Microtubules pull the strings: disordered sequences as efficient couplers of microtubule-generated force
Authors: Volkov Vladimir A. 
Published: June 2020

Abstract
Microtubules are dynamic polymers that grow and shrink through addition or loss of tubulin subunits at their ends. Microtubule ends generate mechanical force that moves chromosomes and cellular organelles, and provides mechanical tension. Recent literature describes a number of proteins and protein complexes that couple dynamics of microtubule ends to movements of their cellular cargoes. These ‘couplers’ are quite diverse in their microtubule-binding domains (MTBDs), while sharing similarity in function, but a systematic understanding of the principles underlying their activity is missing. Here, I review various types of microtubule couplers, focusing on their essential activities: ability to follow microtubule ends and capture microtubule-generated force. Most of the couplers require presence of unstructured positively charged sequences and multivalency in their microtubule-binding sites to efficiently convert the microtubule-generated force into useful connection to a cargo. An overview of the microtubule features supporting end-tracking and force-coupling, and the experimental methods to assess force-coupling properties is also provided.
Reviews on sulphur corrosion phenomenon of the oil–paper insulating system in mineral oil transformer
Authors: Cong Haoxi , Pan Hao , Qian Danyang , Zhao Haiyu , Li Qingmin 
Published: June 2020

AbstractThe active sulphur compounds in transformer oil would react with copper wires and produce cuprous sulphides, which then attach themselves to the surface of copper wires and insulating paper, thus reducing the electrical performance of oil–paper insulation and causing insulation failure. This article aims to make a comprehensive summary on the field of sulphur corrosion of oil–paper insulation in the mineral oil transformer, including the corrosion mechanism of sulphide on copper sheets, the deterioration mechanism of sulphide on oil–paper, the factors influencing sulphur corrosion reaction, the method of characterising the degree of sulphur corrosion, the protection technology of sulphur corrosion and the field operation measures for sulphur corrosion. Moreover, four key problems that need to be further solved were sorted out: the synergistic deterioration mechanism of sulphide and its transformation mechanism, the micro‐process and forming path of sulphur corrosion reaction, the characteristic parameters and quantitative characterisation methods of sulphur corrosion degree, and the effective protection technology of sulphide corrosion. To solve these problems, efforts will be made for deeper understanding of the sulphur corrosion phenomenon and its deterioration mechanism based on theoretical background, the assessment methods and protection technology, endeavouring to put forward solid theoretical basis and feasible technical means for preventing sulphur corrosion insulation failure.

Authors: Kahane Kaustubh J. , Shrivastava Siddhartha , Jarandikar Apurva A. , Phatak Aishwarya S. 
Published: June 2020

AbstractHemangiopericytomas (HPCs) are soft tissue neoplasms that account for 3 to 5% of all soft tissue sarcomas and 1% of all vascular tumors. The vascular tumors originate from pericytes in the head and neck. The most common sites are the nasal cavity, paranasal sinuses, orbital region, parotid gland, and neck. HPC arising from the nose and paranasal sinuses is a rare entity. Till now, less than 200 cases have been reported in the literature. The treatment of choice is complete surgical resection, if possible, combined with preoperative embolization. We are presenting a rare case of HPC of the nasal cavity for its rarity and for concerns in management. This case was managed by endoscopic resection, which gave complete clearance of the disease and achieved better cosmesis.
Sorbents for water purification based on conjugated polymers
Authors: Sapurina Irina Yu. , Shishov Mikhail A. , Ivanova Valeria T. 
Published: June 2020

The sorption properties of polymers with a polyconjugated chain structure (polyaniline and polypyrrole) are considered. The molecular mechanism of sorption by these polymers of various compounds such as heavy metal ions, toxic organic compounds and micropathogens, which are the most hazardous and stubborn contaminants in water, is discussed. The use of such sorbents to purify water from micropathogens, including bacteria and viruses, is addressed for the first time. The adsorption capacity of polyconjugated polymers for these types of contaminants, the efficiency of water treatment by these sorbents and characteristics of the currently used sorbents are analyzed. The applicability of polyaniline and polypyrrole and composites based on them as high-performance versatile sorbents for water treatment is discussed, taking into account the sorbent properties such as high stability, lack of solubility, lack of toxicity and ability to be regenerated and reused.The bibliography includes 194 references.

Metadata mining
Authors: Hacke Melanie 
Published: June 2020

Abstract
Building on a quantitative survey that charts the presence of foreign cultures in the
Edinburgh Review and Quarterly Review, this essay pursues a closer understanding
of the ways in which British Romantic review periodicals engaged in intercultural mediation. After a brief
introduction of the project, the essay zooms in on some of the methodological issues related to the construction and
analysis of the database. As it is the first time that such quantitative research is being undertaken, particular
attention is given to the difficult balance between distant reading of metadata and close readings of specific review
articles, the selection of a representative corpus, and the position of the database within existing research.
The magazine as a medium of cultural translation
Authors: Ehrlicher Hanno 
Published: June 2020

Abstract
Our research project seeks to understand periodical publications as a medium of cultural
translation. This article explains some of the practical challenges which must be confronted when building a digital
corpus which transcends the logic of national archives. Focusing on a specific journal, La Gaceta
Literaria, the article then proceeds to explore data visualizations in a mixed-method approach which aims
at building a bridge between quantitative and qualitative analyses. The project also explores the periodical’s
ambition to construct a global community from an Ibero-American perspective, an aim not without (neo)imperialistic
implications. It does so with a particular focus on the role of translation, and the use of various languages used
within the journal in order to reach this goal.
Digital methods for revisiting twentieth-century magazines of ideas and culture
Authors: Malta Joana , Crespo de Andrade Luís , Lisboa Pedro 
Published: June 2020

Abstract
Considering magazines of ideas and culture are fundamental sources for the history of the first
half of the twentieth century, we propose a discussion of the use of digital and quantitative methods to broaden
knowledge on these historical objects, and bring to light new insights and understanding of the source material,
taking into account the aspects that make magazines a particularly complex object of study. After briefly examining
the advantages and feasibility of studying magazines using non-traditional historiographical methodologies, we explore
how the use of aggregated information can provide visual and comprehensive information not only on the history of
specific periodicals but also on their contents. Using various statistical procedures applied to data on the reception
of foreign authors and works we try to bring forward aspects of cultural transfer present in these magazines. For this
end, we use information gathered by the Semináro Livre de História das Ideias (History of Ideas Free Seminar) research
group for the Revistas de Ideias e Cultura (Magazines of Ideas and Culture) project, illustrating our argument with
data from A Águia, a republican magazine published in Portugal from 1910 to 1932.
The polyphony of periodicals
Authors: Brems Elke , McMartin Jack 
Published: June 2020

Abstract
This chapter introduces the concept of polyphonic voice to investigate the soundscape of a
translation-rich periodical. Using the anglophone Dutch periodical Delta and one of its principle
editors and translators, James S Holmes, as a case, it shows how the “silent voice” of a periodical’s patron can
create dissonance among the voices inscribed in its text; how a periodical’s collective voice can be gleaned through
paratext such as editors’ notes and manifestos; and how paratext can be analyzed to hearken an individual editorial
and translatorial voice within a translation-rich periodical’s collective soundscape.
Human African trypanosomiasis: current status and eradication efforts
Authors: Davis Christopher N. , Rock Kat S. , Keeling Matt J. 
Published: June 2020

Abstract
Epidemics of human African trypanosomiasis (HAT) in the twentieth century led to millions of deaths. However, since the start of the twenty-first century, there has been a continued decline in the number of reported cases, due to increased investment and prioritisation of control efforts. Systematic screening of at-risk areas and widespread access to increasingly advanced diagnostics and treatments, along with much improved vector control, has all helped to make disease elimination achievable in the near future. Despite the progress, the danger of disease resurgence is well known for HAT, and continued surveillance and treatment availability are essential. Additionally, many uncertainties regarding HAT transmission remain and combine to make potential disease eradication a complete unknown.
Evaluating Student’s Misconceptions and The Causes on Direct Current Concepts by Means of Four-Tier Multiple Choice Test
Authors: Aisahsari R , Ermawati F U 
Published: June 2020

Abstract
The main problem commonly faced in learning Physics is incompatibility between students’ pre knowledge in Physics concepts and the Physics concepts taught by teachers in schools. For example in Direct Current concepts, students have assumed that when there are two independent series and parallel current circuits, each composed of two identical electrical lamps as current loads, then the lamps on both circuits will light up at the same intensity. According to the Physics concept, however, the magnitude of current flows on a parallel circuit is greater than the magnitude of similar current flows on a series circuit, so that the intensity of the lamp light on the parallel circuit lights up brighter than that on the series circuit. This discrepancy may introduce a misconception to the students. This research aims to evaluate misconceptions profile of 30 numbers of 12th grade students in senior high school Ngimbang Lamongan East Java on Direct Current concepts and to identify the causes originating from themselves using four-tier multiple choice test developed by the author with ADDIE research design. The results show that all the students experienced misconceptions in throughout the sub concepts. The most frequent misconceptions was identified on the following sub concepts: Parallel Circuit, Series Circuit, Series-Parallel Circuit and Kirchoff’s 1 Law due to wrong intuition.
Identify 11th Grade of Senior High School Jogoroto students’ misconceptions on Dynamic Rotation and Rigid Body Equilibrium concepts using Four-Tier Diagnostic Test
Authors: Jannah E M , Ermawati F U 
Published: June 2020

Abstract
Understanding physics concepts is the main goal of learning process in school. However, it was frequently found that students faced difficulties to understand the concepts on physics taught in class. These difficulties mainly due to the difference between students ’ initial knowledge and the concepts taught by the teacher. For example, students assumed that a top can spin for a long time due to big speed of rotation, so it can maintain the spinning balance. However according to physics concept, the longer spinning balance is caused by the moment inertia is big. When the angular momentum of the top is conserved, the moment inertia can maintain the spinning of the top. This assumption frequently called as preconceptions. The incompatibility of preconceptions with the physics concepts above may lead misconceptions. This study aims to identify conception of students one science class in Senior High School of Jogoroto, Jombang on Dynamic Rotation and Rigid Body Equilibrium and their causes using four-tier diagnostic test. A total of 30 students participated in this study. The instrumen contains 16 numbers of physics-concepts questions. The highest conception is dominated by misconceptions that occur in rotational motion, equilibrium and center of gravity concepts was due to humanistic thinking and praconception.

Abstract
Stocks are a certificate that shows the book of ownership of a company. The certainties of stock price are important for investors. This study aims to predict changes in stock prices. The predicting model of the stock prices in this study uses the non-linear Schrodinger equation. Because this equation has no known analytical solution, so a numerical solution that calculated using the fourth-order Runge-Kutta method to determine the stock prices. This research will also develop an algorithm of numerical solutions in the fourth-order Runge-Kutta method. The analogy of parameters between the nonlinear Schrödinger equation with economic parameters that affect stock prices is obtained based on the hypothesis and the economic theory. The assumed main parameters influence stock prices include movement or growth in average stock prices that is volatility, strike price, speed of average stock returns, adaptive market potential, and current stock price. This present method has been validated to predict the real stock prices of two companies. The prediction results obtain the value of mean absolute percentage error (MAPE) of Astra Agro Lestari Tbk. (AALI) is 0.4633 % and Polychem Indonesia Tbk. (ADMG) is 3.48678 %. Based on these MAPE results, the non-linear Schrodinger equation has shown that good agreement with the real stock price.
