Authors: Karki Binod Kumar
Published: March 2021

Emergency Contraception is a method used to avoid pregnancy after unprotected sexual intercourse or a contraceptive accident to prevent an unwanted pregnancy. This method has potential to prevent up to 75% of unplanned pregnancies. The aim of this study is to assess the information and perception towards emergency contraception among female adolescent students in secondary school.  Secondary classes (+2 Wing) run by Koteshwor Multiple Campus was selected as study area purposively. The study was conducted on November 2018 to December 2018. The study was based on descriptive cross-sectional research design. Self-administered structure and pre-tested questionnaire were used to obtain information and perception from 220 study participants were selected by simple random sampling technique. After data collection, the data was coded, entered, and analyzed by using SPSS version 20. The study shows that 84.5 percentages of the female adolescent students had heard about emergency contraceptive. 85 percentages of them identified the correct timing of use within 72 hours of unsafe sexual contact. 69 percentages respondents said they are ready to use emergency contraceptive if required. There is significant relation between educational level and information of emergency contraceptive. The level of information of emergency contraception among female adolescent students was high but perception towards that was negative while comparing to other studies.Thus,health education intervention regarding information and positive perception towards emergency contraception is needed to female adolescent students of secondary school.

Authors: Lamichhane Pitambar
Published: March 2021

This paper analyzes bank depositors’ perception in relation to factors explaining performance of banks in Nepal. This study has applied descriptive and explorative research design to analyze factors affecting bank performance. A survey was made to collect data from bank depositors using structural questionnaire in Kathmandu valley in 2019. Survey result reveals that Nepalese depositors prefer to deposit money in commercial banks because of easy access but are not satisfied with e-banking services. Most of depositors have no ownership in banks and feel interest rate on deposits is less than expectations. Similarly, result shows that depositors prefer to deposit in saving account analyzing risk and feel government rules and regulations affect interest rates of banks. Further, result indicates banks’ image and interest rate on deposits are key factors for bank deposits and performance, poor operating performance and lack of appropriate investment opportunities are reasons of low interest rate on bank savings. Finally, result concludes that use of modern technologies, size of deposits, market information, managerial efficiency, size of lending and deposits of banks are significant factors and size of debt capital and assets are weak factors affecting performance in Nepalese commercial banks.

Empirics of Solow growth model in Nepali economy
Authors: Paudel Ramesh Kumar
Published: March 2021

Economic growth model developed by R. M. Solow explained the steady-state equilibrium in long run based on neoclassical production function with factor substitutions and diminishing returns in context of developed economy. As the nature of Nepali economy is different than developed economy, this paper aims to analyze economic growth of Nepal in the Solow growth model standard. Specifically, it aims to examine the effect of saving rate, labor growth and human capital on economic growth. On basis of steady-state equilibrium equation developed by Solow, regression equation is developed to find the effect of exogenous variables saving rate and labor growth rate on per capita GDP. Further, the model is extended by adding human capital as regressor. Data of 44 years of Nepali economy are used to analyze the model. Since time series of all the variables are stationary at first difference and they contain same stochastic trend, coefficients are estimated by using ordinary least square method. The analysis shows that the Solow model is applicable to Nepali economy as the predicted coefficients are very close to estimated coefficients. However, the estimated coefficients are very less than the predicted coefficients of the extended model. Furthermore, coefficient of labor growth rate is statistically insignificant in the extended model.

Entrepreneurial Productivity of Single and Non Single Women of Kathmandu Metropolitan City
Authors: Nepal Ratna Mani , Ramtel Om Kumari
Published: March 2021

Despite that women’s socio-economic status is poor, there involvement in entrepreneurial development is low. Data shows that women’s participation in income generating activities and their access to property is quite unsatisfactory. Globally, only eight percent small scale-manufacturing units are owned and operated by women. Compared to the universal statistics, Nepal’s scenario is different because the country owns more than six lakhs small scale manufacturing units. In these units women’s participation is relatively higher. Certain ethnic community, especially the Newar and Tibeto–Burman highland groups such as the Sherpa, Gurung and Thakali, are known to have a long tradition of women being involved in small business enterprises. However, women’s ownership of these enterprises is extremely low. This study aims to examine the entrepreneurial status of single and non-single women who are engaged in entrepreneurial activities in Kathmandu Metropolitan city. It also analyzes the entrepreneurial productivity of the enterprises run by the women. In order to discuss the objectives, primary data was collected from field work. This study found that single women’s involvement in the small businesses was encouraging. The entrepreneurial productivity of the enterprises run by single-women was higher than non-single women.

Authors: Rijal Hima , Maskey Suvana
Published: March 2021

Introduction: Infertility has been rising steeply as the prime health issue among women around the world these days. This study aims to investigate the causes, hormonal profi le, and clinical spectrum of infertility.Materials and Methods: This is a descriptive cross-sectional study conducted throughout a one year duration in an infertility clinic. The couples meeting the inclusion criteria were included and a pre-formed proforma was used to collect the data regarding history, examination, and investigations.Results: A total of 118 infertile couples were analyzed. The mean age of the females was 28.3±4.5 years. There were 72.1 %cases of primary infertility and 27.9 %of secondary infertility. Regarding obesity status,35.5% were overweight and 15.2 % were obese. Thirty-one (26.2%) males were smokers, 41 (34.7%) used to consume alcohol, and 14 (11.8%) had a habit of chewing tobacco. Among the different fi ndings of semen analysis, 21.1% asthenozoospermia, 9.3% oligoasthenozospermia,7.6% oligospermia, 1.6% azoospermia. Female factor accounted for 45.3%, the malefactor for 28% and in 19.3% the defi nite factor was not determined. The ovulatory disorder was diagnosed in 38.6% of females and hysterosalpingography (HSG) revealed that around 10% had a unilateral block and 1.7% had a bilateral block.Conclusions: Infertility is becoming a global issue affecting a signifi cant number of young couples. About forty-six percent were female aging more than thirty years. The female factor for infertility was more common than the male factor among which ovulatory disorder was the commonest one. Asthenozoospermiawas the commonest abnormal fi nding on semen analysis in a male partner.
Associative Remote Viewing for Profit: Evaluating the Importance of the Judge and the Investment Instrument
Authors: Kruth John G.
Published: March 2021

This study examined the importance of the judge and the particular investment selection in the associative remote viewing (ARV) process. In Protocol 1, ARV was used to predict investments and to generate funds. Three viewers made weekly predictions on Sunday about an image they would be shown on Friday. Two images were selected to represent different states of a stock (value increase or value decrease), and a judge reviewed the images and the viewers’ information. Based on the judge’s evaluation, a coordinator informed an investor whether to invest for the stock to rise or fall during the weekly session. Though the sessions lost funds due to a complication in the investment process, this was not the focus of the study. A second judge (Protocol 2) and a mock investment instrument (Protocol 3) were included, blinded to all study participants. The second judge (J2) performed at a significantly less accurate level than the first judge (p < 0.05), and J2 also performed significantly lower than could be expected by chance (p = 0.02; effect size = –1.498; power > .80). Both judges performed significantly differently on the target investment than on a control investment. Although this is a pilot study with a small sample size and a limited number of sessions, conclusions are that the selection of a judge, even a very experienced judge, can have a significant effect on the success of an ARV project and that judges’ decisions are more affected by the target investments than by a comparable control investment. Future ARV projects are advised to qualify judges for accuracy just as they qualify viewers for accuracy.

Erlendur Haraldsson: An Appreciation
Authors: Tucker Jim
Published: March 2021

Erlendur Haraldsson, a prolific researcher who made a number of major contributions in various areas of parapsychology and survival research, died in Reykjavik on November 22, 2020 at the age of 89. Born near Reykjavik, Erlendur studied philosophy in college, but his interest in understanding more about the world began before that. When he was 15, he had an experience during a heavy storm when the sun suddenly shone through the clouds and lit up pebbles on the banks of the nearby shore. As the light reflected off the pebbles, Erlendur sensed being filled with light himself in a way that was immense and beyond words. In an interview with Michael Tymn (2015), he said that a vivid trace of that feeling stayed with him forever and that after that, he never doubted that there was a superior reality. Following college, he worked for three years, mostly as a journalist, before returning to school to study psychology, eventually earning a PhD under Hans Bender in Freiburg. After that, he spent a year working at J. B. Rhine’s parapsychology center in Durham, North Carolina, followed by an internship in clinical psychology at the University of Virginia, where he met Ian Stevenson. He and Stevenson studied an Icelandic medium together, introducing Erlendur to the topic of mediumship which he would return to in subsequent decades. Following his internship, he entered the field with a bang. Karlis Osis, the director of research of the American Society for Psychical Research, invited Erlendur to join him in a large study of deathbed visions. They surveyed hundreds of doctors and nurses in both the United States and India about events they had witnessed in their patients. What resulted was a landmark study, one that exemplified the best the field has to offer—detailed statistical analysis along with compelling individual reports. One striking example involved a two-and-a-half year old boy whose mother had died six months before. The respondent wrote, “He was lying there very quiet. He just sat himself up, and he put his arms out and said, ‘Mama,’ and fell back [dead]” (Osis and Haraldsson, 1977, p. 53).  Osis and Haraldsson found that the data did not support known medical or psychological causes of hallucinations. Likewise, the influences of religious or other cultural factors could not be used to explain away the phenomena.
Signs of Reincarnation: Exploring Beliefs, Cases, and Theory by James Matlock
Authors: Sudduth Michael
Published: March 2021

James Matlock’s Signs of Reincarnation discusses important issues related to the belief in reincarnation. These include the historical and social prominence of this belief in various cultures around the world, especially its place in spiritual and religious communities. Matlock also explores data seemly suggestive of reincarnation and attempts to develop a theory of reincarnation that can account for the data collected by parapsychological investigators and researchers. In this way, Matlock aims to show that belief in reincarnation is defensible as a conclusion drawn from what he calls “signs” of reincarnation.

            Matlock does a good job mapping out the wide range of beliefs about reincarnation across time and culture. His description of various case studies and their salient features is highly informative. And his effort to develop a theory of reincarnation—what he calls a “processual soul theory”—is a laudable attempt at trying to accommodate the various details of interesting case studies and a core idea of reincarnation in the spiritual traditions of the world.

            Unfortunately, this is where my praise ends. Like many other books on the topic, Matlock’s book suffers from a variety of serious defects. The cavalcade of poor scholarship, conceptual confusion, and impoverished argumentation is particularly egregious given that Signs is allegedly based on the lecture notes for Matlock’s course on reincarnation pitched at the advanced undergraduate or Masters-level graduate seminar. In what follows, I’ll explain why Matlock’s book is paradigmatic of nearly everything that’s wrong with survival research over the past thirty years.
SANTA CLAUS SOLIDARITY FOR PALESTINE: A SEMIOTIC ANALYSIS OF THE MOHAMMAD TOROKMAN’S PHOTOJOURNALISM
Authors: Andrea Novan Jemmi
Published: March 2021

Mohammad Torokman is a photojournalist with the Reuters News Agency. Torokman's photojournalism is chosen as "Picture of the Month: December" Reuters in 2017. The photo shows a picture of protesters dressed as Santa Claus throwing stones at the Israeli army when Palestinian protest against unilateral claims by the United States to make Jerusalem the capital of Israel. Torokman's photojournalism not only just evidence of a mere protest, but it has a message and a deeper meaning. This research discusses the denotation and connotation meaning of Torokman’s photojournalism using the semiotics theory of Roland Barthes. This research is descriptive qualitative. This research concludes that Torokman's photojournalism has two meanings: solidarity and resistance. In the first level of analysis, Torokman's photojournalism shows the protestor's opposition to the Israeli army. On the second level of analysis shows the meaning of solidarity, which is shown through joint struggle without regard to religion and belief to maintain its territory in Jerusalem.

Authors: Khomsah Siti
Published: March 2021

Purpose: This study aims to determine the accuracy of sentiment classification using the Random-Forest, and Word2Vec Skip-gram used for features extraction. Word2Vec is one of the effective methods that represent aspects of word meaning and, it helps to improve sentiment classification accuracy.Methodology: The research data consists of 31947 comments downloaded from the YouTube channel for the 2019 presidential election debate. The dataset consists of 23612 positive comments and 8335 negative comments. To avoid bias, we balance the amount of positive and negative data using oversampling. We use Skip-gram to extract features word. The Skip-gram will produce several features around the word the context (input word). Each of these features contains a weight. The feature weight of each comment is calculated by an average-based approach. Random Forest is used to building a sentiment classification model. Experiments were carried out several times with different epoch and window parameters. The performance of each model experiment was measured by cross-validation.Result: Experiments using epochs 1, 5, and 20 and window sizes of 3, 5, and 10, obtain the average accuracy of the model is 90.1% to 91%. However, the results of testing reach an accuracy between 88.77% and 89.05%. But accuracy of the model little bit lower than the accuracy model also was not significant. In the next experiment, it recommended using the number of epochs and the window size greater than twenty epochs and ten windows, so that accuracy increasing significantly.Value: The number of epoch and window sizes on the Skip-Gram affect accuracy. More and more epoch and window sizes affect increasing the accuracy.
Development of technology for repair of shaped elements of pipeline systems in hard-to-reach places
Authors: Doroshenko Ya. V.
Published: March 2021

It is proposed that erosion or corrosion worn out bends of pipeline systems in hard-to-reach places be repaired by trenchless methods by pulling a sleeve or a flexible composite pipe with a piston. The possibility of implementing such an idea is confirmed by theoretical and experimental studies. Mathematical modeling of the process of pulling a sleeve by a piston by a pipeline that contains a defective tap is performed. Formulas are derived for determining all resistance forces acting on a mobile system, patterns of pressure changes at the compressor outlet during such work are determined. A technique has been developed for calculating the friction force between the sleeve and the inner wall of the pipeline at the outlet, due to the pressing of the sleeve through a change in the direction of pulling. The dependence of the required pressure for the piston to extend the sleeve only with a defective bend on the bend angle of the bend is determined. An experimental setup has been developed and built to study the dynamics of the sleeve pulling by a piston. As a result of the experimental tests, it was found that it is possible to extend the sleeve through a pipeline with a piston that contains bend. The resistance forces acting on the moving system, the patterns of pressure change at the beginning of the pipeline in time when the sleeve is pulled by the piston, are experimentally determined. The experimental results are compared with the results of theoretical calculations and the reliability of theoretically derived dependencies is confirmed. The technique and technology for repairing defective pipe bends in hard-to-reach places has been developed by pulling a sleeve or a flexible composite pipe with a piston. The piston moves under the pressure of the air supplied to the piston space by the compressor. A drum with a wound sleeve or flexible composite pipe is placed in a cylindrical sealed chamber. A special supporting device has been developed to place a flexible composite pipe wound into a bay in a cylindrical sealed chamber.

New forms of advertising discourse reconfiguration
Authors: T. Saladounikava T.
Published: March 2021

The article identifies some trends in the process of transformation of advertising discourse. There is a rejection of traditional advertising practices and a shift in advertising communication towards Internet technologies (banners, pop-up notifications). One of the trends in modern advertising communication is the appeal to new methods and tools that allow achieving the goal of an advertising campaign by varying the impact on the advertising consumer. New forms of advertising communication due to the diversification of information carriers are described. Specific features of the reconfiguration of advertising discourse are established: interactivity, shifting the focus from products as such to brand promotion, various forms of advertising mimicry, «blurring» through meta-discursive practices and referring to the game register, «tightening» as a result of referring to shock advertising strategies. There is a radicalization of institutional advertising, manifested in the re-creation of pathos or dysphoria in the field of anti-smoking advertising campaigns, road safety, etc. It is emphasized that significant changes occur both at the level of creating an advertising product (at the stages of determining the target audience, formulating an advertising message, giving it the appropriate form) and at the level of advertising distribution (in particular, choosing the appropriate media for advertising information).

Foi realizado um estudo quase experimental com o objetivo de verificar a evolução do condicionamento físico dos estagiários da Academia da Força Aérea no Estágio de Adaptação Militar no ano de 2017 e a efetividade do plano de treinamento executado pela Seção de Educação Física nesse estágio. O estudo foi realizado na Academia da Força Aérea, localizada em Pirassununga, interior de São Paulo. A amostra foi constituída por 150 militares do sexo masculino, regularmente matriculados nos cursos de Aviação, de Intendência e de Infantaria, aptos à prática de exercícios físicos e que consentiram participar da pesquisa. O estudo foi realizado durante quarenta dias seguidos e constituiu-se de uma avaliação inicial, uma intervenção com exercícios físicos e uma avaliação final. Para a avaliação inicial e final foi utilizado o Teste de Avaliação do Condicionamento Físico, que perpassa por exercícios de flexão de braço, abdominal e corrida. No que se refere à intervenção, foram realizados treinamentos de força em circuito e treinamentos de corrida. Os resultados mostraram que após o treinamento no Estágio de Adaptação Militar de 2017 os militares melhoraram significativamente a condição física, havendo, em média, um acréscimo de 23,28% (10 repetições) no número de flexões, um acréscimo de 5,95% (3 repetições) no número de abdominais e um acréscimo de 12,26% (315,4m) na distância percorrida durante o teste de corrida de 12 minutos. Desta forma, o protocolo de treinamento realizado nesse estudo se mostrou efetivo para aprimorar a condição física dos Estagiários da Academia da Força Aérea. No entanto, sugere-se que sejam realizados estudos futuros para responder à esta questão com mais clareza, utilizando-se testes físicos mais aprimorados.

In a step bearing, when the surface separation is so low that it is comparable with the thickness of the physical adsorbed layer on the bearing surface, the physical adsorbed layer should have an influence on the bearing performance. The present paper presents a multiscale analysis for this multiscale hydrodynamic bearing by considering the effect of the adsorbed layer but neglecting the interfacial slippage on any interface. The adsorbed layer flow is described by the nanoscale flow equation, and the intermediate continuum fluid flow is simulated based on the Newtonian fluid model. The pressure distribution and carried load of the bearing were derived. Exemplary calculations show that when the surface separation in the bearing outlet zone is below 100nm but no less than 10nm, for a weak fluid-bearing surface interaction both the pressure and carried load of the bearing are just slightly higher than those calculated from the conventional hydrodynamic lubrication theory, for a medium fluid-bearing surface interaction the differences are further enlarged, and for a strong fluid-bearing surface interaction the differences are mostly enlarged. The results show the very significant multiscale effect in this bearing resulting in the pronounced improvement of the load-carrying capacity of the bearing by the medium and strong fluid-bearing surface interactions when the surface separation in the bearing outlet zone is below 100nm.
Bioökonomie in Argentinien und Malaysia. Industrial upgrading im Agrarbereich als sozialökologisches Entwicklungsversprechen?
Authors: Puder Janina , Tittor Anne
Published: March 2021

Die Bioökonomie zielt auf eine Abkehr vom fossilen Energie- und Produktionsregime. Dies wird mit der Notwendigkeit der Ressourcenschonung und des Klimaschutzes begründet. Argentinien und Malaysia haben diese Vision übernommen. Dem Agrarsektor in beiden semi-peripheren Ökonomie gelang es seine Interessen in den Bioökonomieagenden beider Länder zu verankern, wodurch Bioökonomie zu einer Entwicklungs- bzw. Industrialisierungsstrategie geworden ist, in dessen Kern das Versprechen eines industrial, social und environmental upgradings steht. Mit der Förderung der Weiterverarbeitung von Agrarprodukten (v.a. Soja und Palmöl) und dem Aufbau von Industrieanlagen im ländlichen Raum forcieren Argentinien und Malaysia eine höhere Wertschöpfung und die Schaffung neuer Arbeitsplätze. Dies stellt im Vergleich zu älteren Entwicklungsstrategien eine Verschiebung dar, mit der die Position semi-peripherer Länder als Exporteure un- bzw. wenig verarbeiteter Agrargüter überwunden werden soll. Allerdings konnte die kritische industriesoziologische Debatte bereits zeigen, dass die Annahme, mit einem industrial upgrading ginge automatisch ein social upgrading einher, sich häufig als falsch erwiesen hat. Ausgehend von der Weltsystemdebatte und des globalen Güterkettenansatzes zeigt der Beitrag, dass ein social upgrading durch die Bioökonomie in Argentinien und Malaysia kaum zu erwarten ist. Wird der eingeschlagene Weg fortgeführt, sind voraussichtlich weder die von den Bioökonomiebefürworter*innen proklamierten Nachhaltigkeits- noch die sozialen Ziele realisierbar.
Zwischen Nakba, Shoah und Apartheid. Nachdenken über Komplizität und Erinnern
Authors: Grunebaum Heidi
Published: March 2021

Die Autorin setzt sich mit persönlicher Verstrickung in drei grundlegende Katastrophen des 20. Jahrhunderts auseinander, die zwar klar voneinander zu trennen sind, dennoch aber miteinander in Beziehung stehen. Diese Wechselbeziehungen zeigt die Autorin beispielhaft an entscheidenden Episoden ihrer eigenen Lebensgeschichte sowie der Erfahrungen ihrer Familie auf. Ihre jüdisch-südafrikanische Herkunft ist Anstoß, den Überresten eines palästinensischen Dorfes nachzugehen, das heute unter dem „Südafrikanischen Wald“ in Israel begraben liegt, für den sie als Kind einmal Geld gesammelt hat; dieser familiäre Zusammenhang führt sie ferner in die oberhessische Kleinstadt, aus der ihrer Großmutter gerade noch die Flucht vor dem Terror der Nationalsozialisten gelungen ist; und sie ist schließlich der leeren Fläche in Kapstadt konfrontiert, wo sich einmal das lebensvolle Viertel District Six befand, in unmittelbarer Nachbarschaft ihres Wohnviertels. Die früheren Einwohner*innen wurden vom Apartheidsregime deportiert. Allen drei Orten ist gemeinsam, dass das, was ihnen hier Bedeutung gibt, durch Gewalt und Verwaltungshandeln ausgelöscht wurde. Durch die Darstellung ihrer eigenen Erfahrung, zu der auch die Arbeit an einem Film über die drei Orte gehört, zeigt die Autorin Möglichkeiten auf, mnemonische Spuren auf persönlicher Ebene und darüber hinaus aufzufinden. Zugleich verweist sie auf die Verstrickung in Komplizität durch die hier angesprochenen Prozesse, mit der sich jegliche ernsthafte Auseinandersetzung konfrontiert sieht. Diese Positionierung steht im Gegensatz zu vereinfachenden und destruktiven Reaktionen auf die Problematik von Komplizität und Komplexität, von Ethnonationalismus und Identitätspolitik.
On asymptotic expansions for the fractional infinity Laplacian
Authors: del Teso Félix , Endal Jørgen , Lewicka Marta
Published: March 2021

We propose two asymptotic expansions of two interrelated integral-type averages, in the context of the fractional ∞-Laplacian [Formula: see text] for [Formula: see text]. This operator has been introduced and first studied in ( Comm. Pure Appl. Math. 65 (2012) 337–380). Our expansions are parametrised by the radius of the removed singularity ε, and allow for the identification of [Formula: see text] as the [Formula: see text]-order coefficient of the deviation of the ε-average from the value [Formula: see text], in the limit [Formula: see text]. The averages are well posed for functions ϕ that are only Borel regular and bounded.

Background: Alzheimer’s disease (AD) is the most prevalent form of dementia worldwide. This neurodegenerative syndrome affects cognition, memory, behavior, and the visual system, particularly the retina. Objective: This work aims to determine whether the 5xFAD mouse, a transgenic model of AD, displays changes in the function of retinal ganglion cells (RGCs) and if those alterations are correlated with changes in the expression of glutamate and gamma-aminobutyric acid (GABA) neurotransmitters. Methods: In young (2–3-month-old) and adult (6-7-month-old) 5xFAD and WT mice, we have studied the physiological response, firing rate, and burst of RGCs to various types of visual stimuli using a multielectrode array system. Results: The firing rate and burst response in 5xFAD RGCs showed hyperactivity at the early stage of AD in young mice, whereas hypoactivity was seen at the later stage of AD in adults. The physiological alterations observed in 5xFAD correlate well with an increase in the expression of glutamate in the ganglion cell layer in young and adults. GABA staining increased in the inner nuclear and plexiform layer, which was more pronounced in the adult than the young 5xFAD retina, altering the excitation/inhibition balance, which could explain the observed early hyperactivity and later hypoactivity in RGC physiology. Conclusion: These findings indicate functional changes may be caused by neurochemical alterations of the retina starting at an early stage of the AD disease.

Authors: Fang Zheng , Chiao Chaoshin
Published: March 2021

The prediction and recommendation of financial stocks are of great values. This study mainly analyzed the application of K-means clustering algorithm in stock forecasting and recommendation. Firstly, it introduced the k-means algorithm briefly and analyzed its advantages and disadvantages. Then, the k-means algorithm was optimized by introducing artificial fish swarm algorithm (AFSA) to obtain KAFSA. Then 100 stocks of listed companies were taken as the research subject and predicted by KAFSA designed in this study. The prediction results were verified through closing price, price earning ratio, earnings per share and return on net assets. The results showed that there were obvious differences between A and B stocks divided by KAFSA, and the differences of B stocks were significantly larger than those of A stocks. It shows that 100 stocks are well divided into high performance stocks and poor performance stocks through clustering, which provides a good reference for investors to invest in stocks and is worth of further application.

Authors: Li Lin
Published: March 2021

A novel method of mirror motion recognition by rehabilitation robot with multi-channels sEMG signals is proposed, aiming to help the stroked patients to complete rehabilitation training movement. Firstly the bilateral mirror training is used and the model of muscle synergy with basic sEMG signals is established. Secondly, the constrained L1/2-NMF is used to extracted the main sEMG signals information which can also reduce the limb movement characteristics. Finally the relationship between sEMG signal characteristics and upper limb movement is described by TSSVD-ELM and it is applied to improve the model stability. The validity and feasibility of the proposed strategy are verified by the experiments in this paper, and the rehabilitation robot can move with the mirror upper limb. By comparing the method proposed in this paper with PCA and full-action feature extraction, it is confirmed that convergence speed is faster; the feature extraction accuracy is higher which can be used in rehabilitation robot systems.

Modeling and simulating durations of men’s professional tennis matches by resampling match features
Authors: Lisi Francesco , Grigoletto Matteo
Published: March 2021

In this paper we analyze the factors impacting on the length of a men’s professional tennis match and propose a model to simulate matches’ durations. Two distinctive features of the model are that i) it considers all kinds of events that impact on the duration of a match and ii) it is based only on publicly available data. Once built, the model allows to analyze the impact of different formats or rule changes on matches’ duration. The model is built and validated using a dataset including 19,961 matches played in the period January 2011 – December 2018. The simulated and observed distributions of the durations are compared with an in-depth goodness-of-fit analysis. This points out that the model provides a good description of the real distribution both in the central part and in the tails. We also show that our model improves similar models present in the literature. Finally, several case studies are analyzed: the effect of abolishing the first service or the advantages or both; the new tie-break format at Wimbledon; and the introduction of fifth set tie-break at Roland Garros.
