Published: November 2020

A newly emerged coronavirus (COVID-19) seriously threatens human life and health worldwide. In coping and fighting against COVID-19, the most critical step is to effectively screen and diagnose infected patients. Among them, chest X-ray imaging technology is a valuable imaging diagnosis method. The use of computer-aided diagnosis to screen X-ray images of COVID-19 cases can provide experts with auxiliary diagnosis suggestions, which can reduce the burden of experts to a certain extent. In this study, we first used conventional transfer learning methods, using five pre-trained deep learning models, which the Xception model showed a relatively ideal effect, and the diagnostic accuracy reached 96.75%. In order to further improve the diagnostic accuracy, we propose an efficient diagnostic method that uses a combination of deep features and machine learning classification. It implements an end-to-end diagnostic model. The proposed method was tested on two datasets and performed exceptionally well on both of them. We first evaluated the model on 1102 chest X-ray images. The experimental results show that the diagnostic accuracy of Xception + SVM is as high as 99.33%. Compared with the baseline Xception model, the diagnostic accuracy is improved by 2.58%. The sensitivity, specificity and AUC of this model reached 99.27%, 99.38% and 99.32%, respectively. To further illustrate the robustness of our method, we also tested our proposed model on another dataset. Finally also achieved good results. Compared with related research, our proposed method has higher classification accuracy and efficient diagnostic performance. Overall, the proposed method substantially advances the current radiology based methodology, it can be very helpful tool for clinical practitioners and radiologists to aid them in diagnosis and follow-up of COVID-19 cases.
Asymmetry of nanoparticle inheritance upon cell division: Effect on the coefficient of variation
Authors: Lijster Tim , Åberg Christoffer
Published: November 2020

Several previous studies have shown that when a cell that has taken up nanoparticles divides, the nanoparticles are inherited by the two daughter cells in an asymmetrical fashion, with one daughter cell receiving more nanoparticles than the other. This interesting observation is typically demonstrated either indirectly using mathematical modelling of high-throughput experimental data or more directly by imaging individual cells as they divide. Here we suggest that measurements of the coefficient of variation (standard deviation over mean) of the number of nanoparticles per cell over the cell population is another means of assessing the degree of asymmetry. Using simulations of an evolving cell population, we show that the coefficient of variation is sensitive to the degree of asymmetry and note its characteristic evolution in time. As the coefficient of variation is readily measurable using high-throughput techniques, this should allow a more rapid experimental assessment of the degree of asymmetry.
A novel quantitative electroencephalography subtype with high alpha power in ADHD: ADHD or misdiagnosed ADHD?
Authors: Byeon Jun , Choi Tae Young , Won Geun Hui , Lee Jaewon , Kim Jun Won
Published: November 2020

This study investigated quantitative electroencephalography (QEEG) subtypes as auxiliary tools to assess Attention Deficit Hyperactivity Disorder (ADHD). A total of 74 subjects (58 male and 16 female) were assessed using the Korean version of the Diagnostic Interview Schedule for Children Version IV and were assigned to one of three groups: ADHD, ADHD-Not Otherwise specified (NOS), and Neurotypical (NT). We measured absolute and relative EEG power in 19 channels and conducted an auditory continuous performance test. We analyzed QEEG according to the frequency range: delta (1–4 Hz), theta (4–8 Hz), slow alpha (8–10 Hz), fast alpha (10–13.5 Hz), and beta (13.5–30 Hz). The subjects were then grouped by Ward’s method of cluster analysis using the squared Euclidian distance to measure dissimilarities. We discovered four QEEG clusters, which were characterized by: (a) elevated delta power with less theta activity, (b) elevated slow alpha relative power, (c) elevated theta with deficiencies of alpha and beta relative power, and (d) elevated fast alpha and beta absolute power. The largest proportion of participants in clusters (a) and (c) were from the ADHD group (48% and 47%, respectively). Conversely, group (b) mostly consisted of the participants from the NOS group (59%), while group (d) had the largest proportion of participants from the NT group (62%). These results indicate that children with ADHD does not neurophysiologically constitute a homogenous group. We also identified a new subtype with increased alpha power in addition to those commonly reported in ADHD. Given the QEEG characteristics with increased alpha power, we should consider the possibility that this subtype may be caused by childhood depression. In conclusion, we believe that these QEEG subtypes of ADHD are expected to provide valuable information for accurately diagnosing ADHD.
Performed intermediality and beyond in the BTS music video ‘Idol’: K-Pop idol identities in contemporary Hallyu
Authors: Kim Yeogeun Yonsue
Published: November 2020

The recent music video ‘Idol’ (published 24 August 2018) by South Korean boy band BTS exhibits extensively Korean elements, compared to previous visual presentations of BTS music. This may be because the song ‘Idol’ attempts to explicitly delineate BTS’s identity not only as a musician in general but also as a K-Pop artist, in particular, in the context of Hallyu (the Korean Wave). The music video ‘Idol’ is an effort to visually deal with these twofold difficulties that BTS confronts as a boy band, branded also as an idol group from South Korea. To this end, throughout the music video, intermediality – the interconnectedness of various media practices – is extensively performed to open up the third way to communicate what is yet to be difficult to convey otherwise: BTS’s identity as a K-Pop artist in relation to Hallyu. Intermediality is further stretched to the extent that the nature, to be relevant, the identity of one medium is questioned and its figuration is transformed into another medium. This article examines ways in which intermediality as manifested and performed in the music video ‘Idol’ contributes to this goal by analysing various arts and media demonstrated in a combination of architecture, writings, photographs, drawings, paintings, music and dance.
‘So, he is practically a Korean?’: Power relations and re-articulation of the Korean Self in the TV show Non-Summit
Authors: Eydam Tanja
Published: November 2020

Korean national identity is defined by nationalist sentiment and a mono-ethnic self-image. Having turned into a migrant-receiving country, Korea is slowly transforming into a multicultural society. The contemporary popularity of television shows with migrant representation reflects this change. The question arises how migrants get depicted in these popular broadcasting shows and what this portrayal of non-Koreans reveals about re-articulations of the Korean Self. As a response to these questions, a critical discourse analysis of Episodes 1 and 103 of the show Non-Summit (Bijeongsang hoedam 2014–17) is conducted. Corresponding to Koller’s (2011) combined discourse-historical and socio-cognitive approach, macro-, meso- and micro-level are analysed separately. Overall, Non-Summit reproduces Korean discourse on multiculturalism as ‘happy talk’, as the avoidance of in-depth consideration of inequality, the reproduction of ‘western’ norms and the normativity of Koreanness. This results from predominantly selecting Caucasians and constructing them as ‘para-Koreans’ who can then be readily consumed. These practices enable the Korean Self to position itself as analogous to western, modern norms. This positioning mirrors the influence of ‘nouveau-riche nationalism’ and the Korean ‘will to greatness’. The show further consolidates existing societal norms in Korea (Kang 2017: 14) on four different levels of power relations between Korean producers/writers and migrant population in Korea, non-Korean cast and migrant population in Korea, Korean producers/writers/hosts and non-Korean cast, and Korean viewers and non-Korean cast, and hierarchizes modern and traditional values. Thereby, Non-Summit reproduces the South Korean struggle to reconstruct a homogenous national identity in the face of a rising ethnic diversity within the country.
Ecological Exhibitions at the Musée Océanographique de Monaco
Authors: Wade Sarah
Published: November 2020

In 2010, the Musée Océanographique de Monaco initiated a contemporary art programme to mark its centenary and reaffirm its commitment to its founding premise of displaying objects of both art and science. Ever since, the museum has regularly staged exhibitions promoting marine wildlife protection. I argue that as well as examining ecological concerns, these exhibitions have functioned in ecological ways, adopting curatorial approaches that traverse art and science to highlight interconnections between humans and ocean life. By revisiting historical modes of display, such as the Wunderkammer, and deploying anthropomorphism, the museum presents ecologies of display that aim to evoke solidarity with marine wildlife. Yet, ambiguity arises when considering these exhibitions in the context of this institution and its longer history, which I suggest requires an ongoing curatorial commitment to finding creative and thoughtful ways of responding to ecological issues in museums.

Safe Spaces for Enabling the Creative Process in Classrooms
Authors: Fuss Monique , Daniel Graham ,   Charles Stuart University
Published: November 2020

Based on interviews with five creative professionals this article looks to investigate the creative experience as a source of data on how educators might create space for enabling the creative process in the classroom. Looking toward professional artists who are also committed educators provides core commentary on how to maximise creative experiences in the classroom. Whilst acknowledging the importance of physical space, the following article looks purposefully toward how to enable space as an internal state of being, with the intent toward establishing transdisciplinary discussions that stimulate and provoke creative pedagogical research across an interdependent continuum. The research concludes that enabling space for the creative process lies in the educators’ ability to create safe physical, social and emotional spaces for exploring creative processes. Implications for initial teacher education, professional development and classroom practice are identified.
Making a Difference to the Student Experience Through Purposeful Course Design
Authors:   Charles Sturt University, Zundans-Fraser Lucia , Bain Alan ,   Charles Sturt University
Published: November 2020

The study described examines the student experience in a graduate inclusive education course purposefully designed to address areas of need identified. These include the need for theory to underpin course design, the need for collaborative practice, and the need to reduce the theory-to-practice gap. Throughout their enrolment and after course completion, feedback from students is presented and examined in order to determine whether these needs have been met through the design of the course. Findings suggest that the organisation of learning materials, embedded capacity-building skills, and the practical applicability of course content was highly regarded by students and contributed to their learning. Additionally, the design process used addressed the areas of need identified in an authentic way.

Published: November 2020

A distribuição desigual da infraestrutura de saneamento nos municípios brasileiros propicia que a proliferação de determinadas doenças atinja grupos populacionais de forma diferente. Esse trabalho objetiva analisar as relações entre as condições sanitárias e a saúde ambiental no estado do Rio de Janeiro, no período de 2007 a 2014.  Para isso foram utilizados indicadores de saneamento do Censo Demográfico de 2010 relacionados às condições de infraestrutura dos domicílios particulares permanentes atendidos por abastecimento de água, esgotamento sanitário e coleta de lixo. Dados sobre as doenças relacionadas ao saneamento ambiental inadequado, como a dengue e a hepatite, foram obtidos no DATASUS. Foram aplicadas técnicas de geoprocessamento, de estatística descritiva e de análise multivariada. Observou-se que a dengue apresentou número de ocorrências mais elevado em relação à hepatite, no entanto a primeira apresentou oscilação interanual dos números de casos, enquanto as ocorrências da hepatite exibiram tendência de crescimento no período estudado. A dengue e a hepatite apresentaram maior correlação com a renda média domiciliar mensal, enquanto a hepatite revelou também correlação com os domicílios particulares permanentes com fossa séptica. Por fim, conclui-se que, com os procedimentos metodológicos aqui utilizados, foi possível compreender a distribuição espacial das doenças e seu relacionamento com os indicadores sócios sanitários. Desta forma, podem auxiliar no mapeamento dos riscos e, assim, na adoção de políticas públicas de saúde.

Published: November 2020

Atualmente, as mais diversas áreas da ciência buscam no passado dados para entender o presente e construir o futuro, indicando como a história é importante em nossas vidas. No Cadastro Territorial Multifinalitário (CTM) não é diferente, conhecer como eram os dados do CTM no passado pode indicar como houve a ocupação de um território e permite planejar como se desenvolverão as próximas ações de ocupação. O objetivo deste trabalho é apresentar uma metodologia para a organização de dados temporais para o CTM. A proposta metodológica consiste em uma série de etapas que, a partir do conceito de Data Warehousing, possibilitam organizar dados históricos, provenientes de diferentes fontes, unindo-os a dados atuais para gerar novas informações. Este método, aliado às ferramentas tecnológicas, permitiram unir em uma mesma base de dados, dados "diferentes" em sua estrutura e semântica, adquiridos em épocas distintas. Esse procedimento disponibiliza a história dos dados cadastrais, permitindo verificar como era, como é e fazer uma previsão do futuro daquele dado. A proposta metodológica se mostrou viável porque todas as tecnologias empregadas são livres e também porque as etapas são iterativas, ou seja, uma vez construído o modelo multidimensional, novas bases de dados podem ser inseridas no CTM temporal, baseado no Data Warehousing.

Published: November 2020

This study analyzes the socio-occupational distribution in the Paraíba Valley and North Coast Metropolitan Region (in Portuguese: Região Metropolitana do Vale do Paraíba e Litoral Norte – RMVPLN) Subregion 4 using spatial microsimulation techniques. To fulfill the proposed objective, the Iterative Proportional Fitting (IPF) technique was used to obtain spatial microdata in the territorial census tracts unit through the 2010 Brazilian Demographic Census. After the Skater regionalization technique was applied, eight homogeneous socio-occupational groups were found. Overall, the proposed socio-occupational categories, studied at an intra-urban scale, allowed for highlighting the social structure on a subregion of the newest Metropolitan space in the São Paulo state. Although this is a preliminary study, it is already capable to identify inequalities degrees that consistently spatially segregate and the less privileged population socioeconomic groups.

One of the ecological functions of the seagrass ecosystem is the ability to absorb carbon coming from the atmosphere. The ability of seagrass to absorb carbon is carried out through photosynthesis. The absorbed carbon will then be stored in the form of seagrass biomass in the seagrass body. This study aims to estimate the carbon stock content stored in seagrass ecosystems in the Northern waters of Papua including on Liki Island, Befondi Island, and Meossu Island. The calculation of carbon stock is done by converting seagrass biomass using constants derived from representative values of seagrass carbon content in Indonesian waters. In general, based on the results obtained indicate that the biomass at the bellow ground of the seagrass is greater than the biomass at above ground the seagrass. The value of organic carbon content in seagrasses is influenced by seagrass biomass. The carbon stock content in the seagrass ecosystem in the study area is in the range of 18,04 – 419,46 g C / m2. Stations on Liki Island have generally higher carbon stocks compared to stations on other islands.Salah satu fungsi ekologi dari ekosistem lamun yaitu memiliki kemampuan dalam menyerap karbon yang berasal dari atmosfer.

Published: November 2020

(Title: Physical and Inner Structure of the Poetry of Kimi Shinita Mou Koto Nakare by Yosano Akiko) This research examines Japanese poem shintaishi, Kimi Shinita Mou Koto Nakare by Yosano Akiko using structural and feminism approach. This research aims to understand the structurally context and the meaning of feminism contained in the poem. Yosano Akiko, whose real name is Shou Hou, is the first famous Japanese female poet in the late Meiji era. At that time when Japan was struck by war, the position of women in social and political life had shifted the view that physically women are not strong enough to contribute to the war that reduced the role of women. Women do not see war with an objective view but rather see it subjectively, which they associated with the author’s own condition. The results showed that in addition to convey her aspirations as a woman after the war, there were several images which are contained in Kimi Shinita Mou Koto Nakare.

Nietzsche’s English Genealogy of Truthfulness
Authors: Queloz Matthieu
Published: November 2020

This paper aims to increase our understanding of the genealogical method by taking a developmental approach to Nietzsche’s genealogical methodology and reconstructing an early instance of it: Nietzsche’s genealogy of truthfulness inOn Truth and Lie.Placing this essay against complementary remarks from his notebooks, I show that Nietzsche’s early use of the genealogical method concerns imagined situations before documented history, aims to reveal practical necessity before contingency, and focuses on vindication before it turns to subversion or problematization. I argue that we understand Nietzsche’s later critique of truthfulness better if we place it against the background of his earlier vindicatory insight into the practical necessity of cultivating truthfulness in some form; and I suggest that Nietzsche’s own mature genealogical method has roots in its supposed contrary, the method of the “English” genealogists.
On the sharp interface limit of a model for phase separation on biological membranes
Authors: Abels Helmut , Kampmann Johannes
Published: November 2020

We rigorously prove the convergence of weak solutions to a model for lipid raft formation in cell membranes which was recently proposed in [H. Garcke, J. Kampmann, A. Rätz and M. Röger, A coupled surface-Cahn–Hilliard bulk-diffusion system modeling lipid raft formation in cell membranes, Math. Models Methods Appl. Sci. 26 2016, 6, 1149–1189] to weak (varifold) solutions of the corresponding sharp-interface problem for a suitable subsequence. In the system a Cahn–Hilliard type equation on the boundary of a domain is coupled to a diffusion equation inside the domain. The proof builds on techniques developed in [X. Chen, Global asymptotic limit of solutions of the Cahn–Hilliard equation, J. Differential Geom. 44 1996, 2, 262–311] for the corresponding result for the Cahn–Hilliard equation.
Insights in thixotropic concrete pumping by a Poiseuille flow extension
Authors: De Schryver Robin , De Schutter Geert
Published: November 2020

Thixotropy is a reversible time-dependent phenomenon in fluids, in which an internal structure grows due to flocculation and breaks down under shear action. Numerous fluids are thixotropic,e.g.concretes and cementitious suspensions. Pumping of concrete is an important application. Since current approaches omit thixotropic effects, we aim to develop a simple theoretical model to evaluate or understand the significance of thixotropy on the concrete pumping behaviour. We therefore extended Poiseuille flow for thixotropic concretes and reformulated it in a dimensionless form to gain insights. After a validation, the results and significance are elaborated and concluded.

Results showed that for increasing thixotropy and decreasing flow rates, the plug radius, wall shear rate and pumping pressure loss increase. Even though all thixotropy mechanisms may not be covered, a simple model is delivered to interpret or predict the effect of thixotropy on the pumping behaviour of cementitious suspensions. The dimensionless formulations via the Bingham numberBnand related discharge diagrams are sufficiently elegant for computational implementation and very insightful to distinguish a thixotropic flow regime. The model could be extended for more complicated thixotropies, irreversible time-dependent effects or even other pumping related phenomena.

Changes Over Time in the Cost of Job Loss for Young Men and Women
Authors: Barnette Justin , Odongo Kennedy , Reynolds C. Lockwood
Published: November 2020

Using data from the two cohorts of the NLSY, we examine whether income losses due to involuntary job separations have changed over time. We find that wage losses among men are similar between the two cohorts. However, women in the 1979 cohort show little evidence of wage losses while women in the 1997 cohort experience wage losses similar to those of men. We present evidence that changes in occupations across cohorts help explain these results.
Preparation of konjac oligoglucomannans with different molecular weights and their in vitro and in vivo antioxidant activities
Authors: Yang Weidong
Published: November 2020

In this paper, konjac oligoglucomannan (KOGM) was obtained with a hydrolysis rate of 56.24% by controlling the hydrolysis conditions. KOGM was passed through a 0.2 kDa dialysis bag, a 3 kDa ultrafiltration tube, and a 5 kDa ultrafiltration tube, creating samples with molecular weights of 0.2–3 kDa (IV), 3–5 kDa (III), and >5 kDa (II), respectively. The in vitro antioxidant activities of the KOGM samples were tested by measuring their removal effects on ˙OH, {\text{O}}_{2}^{-}, and DPPH˙. The in vivo antioxidant activities of the samples were analyzed by measuring their impacts on the malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, and glutathione peroxidase (GSH-PX) activity in mice. The results show that the KOGM samples in groups III and IV could effectively remove ˙OH, {\text{O}}_{2}^{-}, and DPPH˙; the KOGM samples in all three groups could enhance the SOD and GSH-PX activities and reduce the MDA content in the liver tissues of mice; finally, the antioxidant activity of KOGM is negatively correlated with the molecular weight.
Basic Income, Labour Automation and Migration – An Approach from a Republican Perspective
Authors: Fischer Yannick
Published: November 2020

This research uses a normative approach to examine the relationship between basic income and migration. The decisive variable is the effect of labour automation, which increases economic insecurities globally, leaving some nation states in a position to cope with this and others not. The insecurities will increase migratory pressures on one hand but also justify the introduction of basic income on a nation state level on the other.

The normative guideline is the republican conception of freedom as non-domination. This is used to justify a basic income, analyse how labour automation creates dominating structures and how borders dominate migrants seeking to move to countries which introduce a basic income.

The result is that nation states that introduce a basic income to counter internal domination through labour automation, also have to look outside of their nation state. The imposition of borders in order to keep a basic income sustainable as well as labour automation itself, establish a form of domination over less developed countries and thus demand international regulation.
Shell-supported footbridges
Authors: Fenu Luigi , Congiu Eleonora , Marano Giuseppe Carlo , Briseghella Bruno
Published: November 2020

Architects and engineers have been always attracted by concrete shell structures due to their high efficiency and plastic shapes. In this paper the possibility to use concrete shells to support footbridges is explored. Starting from Musmeci’s fundamental research and work in shell bridge design, the use of numerical form-finding methods is analysed. The form-finding of a shell-supported footbridge shaped following Musmeci’s work is first introduced. Coupling Musmeci’s and Nervi’s experiences, an easy construction method using a stay-in-place ferrocement formwork is proposed. Moreover, the advantage of inserting holes in the shell through topology optimization to remove less exploited concrete has been considered. Curved shell-supported footbridges have been also studied, and the possibility of supporting the deck with the shell top edge, that is along a single curve only, has been investigated. The form-finding of curved shell-supported footbridges has been performed using a Particle-Spring System and Thrust Network Analysis. Finally, the form-finding of curved shell-supported footbridges subjected to both vertical and horizontal forces (i.e. earthquake action) has been implemented.

. First, we investigate the series expansion of the definition of the modified Hilbert transformation, where the truncation parameter has to be adapted to the mesh size. Second, we introduce a new series expansion based on the Legendre chi function to calculate the corresponding matrices for piecewise polynomial functions. With this new procedure, the matrix entries for a space-time finite element method for parabolic evolution equations are computable to machine precision independently of the mesh size. Numerical results conclude this work.
A Space-Time Adaptive Algorithm to Illustrate the Lack of Collision of a Rigid Disk Falling in an Incompressible Fluid
Authors: Dubuis Samuel , Picasso Marco , Wittwer Peter
Published: November 2020

A space-time adaptive algorithm to solve the motion of a rigid disk in an incompressible Newtonian fluid is presented, which allows collision or quasi-collision processes to be computed with high accuracy. In particular, we recover the theoretical result proven in [M. Hillairet,
Lack of collision between solid bodies in a 2D incompressible viscous flow,
Comm. Partial Differential Equations 32 2007, 7–9, 1345–1371], that the disk will never touch the boundary of the domain in finite time. Anisotropic, continuous piecewise linear finite elements are used for the space discretization, the Euler scheme for the time discretization. The adaptive criteria are based on a posteriori error estimates for simpler problems.
Gasification of Glycerol Over Ni/γ-Al2O3 For Hydrogen Production: Tailoring Catalytic Properties to Control Deactivation
Authors: Umar Ahmed , Irvine John T.S.
Published: November 2020

The effects of catalyst loading, calcination and reaction temperatures on the structural properties and catalytic behavior of Ni/γ-Al2O3 catalyst system in relation to steam reforming of glycerol and catalyst deactivation were investigated. The results showed that catalyst loading, reaction and calcination temperatures had a profound influence on the structure and catalytic activity in glycerol conversion. Use of high calcination temperature (900-1000 °C) led to phase transformation of the active Ni/Al2O3 to less active spinel specie NiAl2O4 that resulted in a successive change of texture and color. The particle size growth and phase change at this temperature were responsible for the catalyst deactivation and low performance especially among the catalyst calcined at high temperatures. Conversely, at low reaction temperatures, catalyst surfaces were marred by carbon deposition. Whilethe polymeric carbon deposited at metal-support interface was associated with low reaction temperatures, high reaction temperatures were characterized predominantly by both amorphous carbon deposited on the active metal surface and polymeric or graphitic carbon deposited at metal-support interface respectively. Calcination temperature showed no significant influence on the location and type of coke deposited on the catalyst surface. Hence, catalyst loading, calcination and reaction temperatures could be tailored to enhance structural and catalytic properties and guard against catalyst deactivation.

European Insider Trading Theory Revisited: The Limits of the Parity-of-Information Theory and the Application of the Property Rights in Information Theory to Activist Investment Strategies
Authors: Taleska Ana
Published: November 2020

Parity-of-information is purported to be the single overarching policy rationale for the European Union (EU) regulation on insider trading. This is because securities trading on the basis of informational advantages is generally prohibited under EU rules, as is tipping (and issuers’ selective disclosure) of material, non-public information. Yet, EU regulations allow market actors, including investment professionals and analysts, that have discovered valuable information -and thereby, have an informational advantage vis-à-vis their trading counterparties- to trade on this information. Relatedly, issuers of financial instruments, takeover bidders and merging parties can share information with a selected group of investors prior to public announcement of the transaction (market sounding), whereas firms can delay public disclosure of inside information and prevent all other market participants from trading on this information. I argue that these exceptions from the parity-of-information theory are -from a doctrinal standpoint- best explained as property rights in information of market actors that have developed new proprietary information with respect to European listed securities. This article, therefore, aims at providing a property rights account of the exceptions to the parity-of-information theory and it illustrates the trade-offs between the parity-of-information and the property rights in information theories underlying European insider trading rules. By extension, I analyze the specific case of activist campaigns as inside information and argue that it would be consistent with the property rights approach to allow activist investors to share their investment and trading strategies with other market participants that further their activist agenda.
The Reflected-Shifted-Truncated Lindley Distribution with Applications
Authors: Dey Sanku , Waymyers Sophia , Kumar Devendra
Published: November 2020

In this paper, a new probability density function with bounded domain is presented. The new distribution arises from the Lindley distribution proposed in 1958. It presents the advantage of not including any special function in its formulation. The new transformed model, called the reflected-shifted-truncated Lindley distribution can be used to model left-skewed data. We provide a comprehensive treatment of general mathematical and statistical properties of this distribution. We estimate the model parameters by maximum likelihood methods based on complete and right-censored data. To assess the performance and consistency of the maximum likelihood estimators, we conduct a simulation study with varying sample sizes. Finally, we use the distribution to model left-skewed survival and failure data from two real data sets. For the real data sets containing complete data and right-censored data, this distribution is superior in its ability to sufficiently model the data as compared to the power Lindley, exponentiated power Lindley, generalized inverse Lindley, generalized weighted Lindley and the well-known Gompertz distributions.
Electrical equivalent circuit modelling of various fractal inspired UWB Antennas
Authors: Biswas Balaka , Karmakar Ayan
Published: November 2020

This paper presents electrical equivalent circuit modelling of various fractal-based UWB antennas. Three different designs have been discussed here as case studies, whose characteristics are diversified in nature. Even the implemented fractal geometries are also unique in nature for these antenna problems. An easy circuit model for each antenna structure is proposed which deciphers the insight device physics of the structure. Without applying much more complicated mathematical jugglery, the models have been presented here. Finally, a comparison of FEM simulated data and the result obtained from circuit modelling is concluded, which establishes the validity of the proposed models.
Numerical simulation for the effects of waves and grain size on deltaic processes and morphologies
Authors: Liu Yang , Chen Hongde , Wang Jun , Yang Shuai , Chen Anqing
Published: November 2020

Currently, the sedimentation process concerning the formation of the morphological changes of deltas under the action of waves has received little attention. Two numerical simulations were carried out in this study to explore the sedimentary morphological changes of deltas under wave action. In the first experiment, the morphological characteristics of river-dominated deltas and wave-dominated deltas were compared. Results showed that a wave-dominated delta was more likely to produce slender and stable rivers relative to a river-dominated delta. In the second experiment, the morphologies of wave-dominated deltas with sediments of different grain sizes were compared. Results indicated that delta morphology was not significantly correlated with the median grain size (ϕ50{\phi }_{50}) of the sediment, and the average grain size of the coarser sediments (ϕ25{\phi }_{25}) was an important factor affecting delta morphology. Moreover, a delta with a largerϕ25{\phi }_{25}value of the input sediment, a smaller topset gradient, and a smaller number of active river channels had a more arcuate shape. The results showed that the hydrodynamic numerical simulation method has the ability to reveal the evolution of deltas under the action of waves. The final simulation results were consistent with the actual delta data.
On functions continuous with respect to a density type strong generalized topology
Authors: Hejduk Jacek , Loranty Anna
Published: November 2020

In the paper, some properties of functions continuous with respect to a density type strong generalized topology are presented. In particular, it is proved that each real function is approximately continuous with respect to this generalized topology almost everywhere. Moreover, some separation axioms for this generalized topological space are investigated.
Determination of life cycle GHG emission factor for paper products of Vietnam
Authors: Ta Thi Yen , Thi Anh Tuyet Nguyen
Published: November 2020

The paper industry is an essential but energy-intensive economic sector. This study aims to propose an appropriate inventory method to first determine the GHG emission factor in the life cycle of paper products of Vietnam. The approach overcomes the limitations of the ISO 14067 method by including the environmental burdens from the paper mill’s processes. In 2018, the amount of GHG emitted from cradle to gate when producing a ton of carton box, writing paper, and tissue products ({\text{EF}}_{{\text{CO}}_{\text{2eq}}}) was 1,366 kg CO2eq, 1,224 kg CO2eq, and 751 kg CO2eq, respectively. High energy intensity is identified as the main reason that causes high life cycle analysis (LCA) GHG emission factors and virgin paper-based products often emit higher LCA GHG amounts than recycled paper-based products. To reduce the emission, the Vietnamese paper mills should increase the use of recycled paper and replace fossil fuels with environmentally friendly energy resources.
“If we don’t quarrel, we joke”: Emic perspectives on Belarusian families’ humorous folklore
Authors: Fiadotava Anastasiya
Published: November 2020

The paper discusses Belarusian couples’ reflections on the role of humorous folklore in their daily family interactions. The interviewees generally regarded being humorous as a positive feature and identified (explicitly or implicitly) several functions of humor, such as framing group boundaries, offering criticism, and sharing ideas that would otherwise be difficult to communicate. A recurring distinction evoked by respondents was between “good” (benevolent) and “bad” (offensive) humor. However, interviews also revealed that the actual perception of humor, especially in the form of mocking and teasing, can be very context-specific, and the boundary between aggression and playfulness is not always clear-cut. The paper explores this ambiguity by examining self-reported instances of mocking and teasing, whereupon the producer and the recipient of humor need to resolve the tension between “having a good sense of humor” and using humor in an offensive or aggressive way. The couples’ attitudes towards family humor are discussed within the broader context of the value of humor in modern society. The paper also reflects on the limitations of using the interview as a data collection method for studying family humor.
Slavic *ljuby and the heterogeneity of the inflectional class in *‑y
Authors: Majer Marek
Published: November 2020

The inherited Proto-Slavic feminine nouns in nom. sg. *‑y, oblique *‑ъvare conventionally thought to go back to one source only, namely Proto-Indo- European stems in *‑uh‑. However, a handful of previous studies have already demonstrated the possibility that other inherited items could join this paradigm by phonologically developing a nom. sg. in *‑y from other sources (particularly *‑ōs). Accordingly, in the present article, it is hypothesized that the well-known PSl. noun *ljuby *ljubъve f. ‘love’ may go back to an amphikinetic s‑stem *lewbʰ‑ōs. Such a reconstruction makes it possible to explain a number of otherwise problematic features of the complex of *ljuby, such as: 1) the enigmatic OCS acc. sg. ljuby (for expected ljubъvь) in the collocations (prě)ljuby (sъ)tvoriti or (prě)ljuby dějati ‘commit adultery’; 2) the unexpected presence of *‑s‑ in the Balt. cognate, Lith. liaupsė̃ f. ‘praise, adoration’; 3) the occurrence of PSl. *‑y as an abstract marker (a function in which PIE amphikinetic s‑stems in *‑ōs are securely, even if marginally, found, particularly in the domain of emotions and mental states - cf. Gk. αἰδώς αἰδόος f. ‘reverence, awe’, ἔρως *ἔροος m. ‘love, desire’, Ved. bhiyás‑, Av. biiah‑ m. ‘fear’ - while no such function can convincingly be reconstructed for a formation in *‑u‑h₂).
Research on intelligent substation monitoring by image recognition method
Authors: Tang Weijie , Chen Honggang
Published: November 2020

This study mainly analyzed the improved three-frame difference algorithm for the identification of active targets in the intelligent substation. The improved three-frame difference algorithm introduced the Gaussian mixture background algorithm on the basis of the traditional three-frame difference method. The Gaussian mixture background algorithm, traditional three-frame difference method, and improved three-frame difference method were tested in the actual substation. The results showed that the improved difference method eliminated the non-target background more thoroughly when recognizing the moving target in the image; in the tested video, the improved algorithm had the highest precision and recall ratios for the active target in the video. To sum up, the improved three-frame difference method can more accurately and effectively identify the active targets in the monitoring video, so as to provide an effective support for the unmanned monitoring of intelligent substation.
