GEM/Kir is differentially expressed in multiple models of coronavirus infection.
Authors: Mamoor Shahan
Published: April 2020

The coronavirus COVID19 pandemic is an emerging biosafety threat to the nation and the world (1). There are no treatments approved for coronavirus infection in humans (2) and there is a lack of information available regarding the basic transcriptional behavior of human cells and mammalian tissues following coronavirus infection. We mined multiple independent public (3) or published datasets (4-7) containing transcriptome data from infection models of human coronavirus 229E, the severe acute respiratory syndrome (SARS) coronavirus and Middle East respiratory syndrome (MERS) coronavirus to discover genes whose differential expression was conserved across the coronavirus family. We identified the GTP binding protein overexpressed in skeletal muscle, GEM (8), also known as Kir, as a differentially expressed gene following infection of human cells with two types of MERS coronavirus, after infection of human cells with human coronavirus 229E, and in the lungs of mice and ferrets infected with SARS coronavirus. GEM induction after viral infection appears to be conserved across the coronavirus family and may be found in patients infected with the novel coronavirus SARS-CoV-2.
Large Eddy Simulation of liquid metal turbulent mixed convection in a vertical concentric annulus
Authors: Marocco Luca , Garita Francesco
Published: April 2020

In the present study turbulent forced and mixed convection heat transfer to a liquid metal flowing upwards in a concentric annulus is numerically investigated by means of Large Eddy Simulation (LES). The inner-to-outer radius ratio is 0.5. The Reynolds number based on bulk velocity and hydraulic diameter is 8900, while the Prandtl number is set to a value of 0.026. A uniform and equal heat flux is applied on both walls. LES has been chosen to provide sufficiently accurate results for validating Reynolds-Averaged turbulence models. Moreover, being the thermal sublayer thickness of liquid metals much larger than the viscous hydrodynamic one, liquid metals present a separation between the turbulent thermal and hydrodynamic scales. Thus, with the same grid resolution it is possible to perform a LES for the flow field and a “thermal“ Direct Numerical Simulation (DNS) for the temperature field. Comparison of the forced convection results with available DNS simulations shows satisfying agreement. Results for mixed convection are analyzed and the differences with respect to forced convection at the same Reynolds number are thoroughly discussed. Moreover, where possible, a comparison with air is made.
Population dynamics and socioeconomic indicators in intramunicipal scale: Municipalities of Altamira and São Félix do Xingu, Pará State, between 2000 and 2010
Authors: Dagnino Ricardo
Published: April 2020

This works deals with the internal socioeconomic differences on the municipalities of Altamira and São Félix do Xingu, Pará state, situated on the frontier expansion of Amazonia The methodology comprises three procedures. The first, acquiring information, was the construction of 52 socioeconomic indicators (illiteracy, income) and demographic indicators (age structure, sex ratio) referred to intra-municipal level. The source used was the Demographic Census of 2000 and 2010 and the 2007 Population Count, by the Brazilian Institute of Geography and Statistics (IBGE), that present data aggregated by census tracts (between 100 and 300, depending on the year), which is the smallest unit data representation. The second procedure, processing information, was the definition of 29 intra and trans municipal spatial units by grouping census tracts according to their situation (rural and urban) and type of locality (village, town, city) and criteria that enable the monitoring of its temporal trajectory (2000-2010). The third, supported by the Bertin's "weighted and exchangeable matrix", permitting the "cross" of the 52 indicators with 29 spatial units, led to the construction of 11 units of these clusters, allowing the verification of socioeconomical differences (and similarities) between them. Since the object of analysis, designed by the methodology, is intramunicpal space, it becomes possible to capture existing socioeconomic differences between: (1) urban and rural spatial units; (2) urban spatial units of different types; (3) rural units located within and outside protected areas; and (4) rural units located in two types of protected areas (indigenous lands and conservation units). The results obtained allows synchronic analysis, by comparing between indicators of different classes in the same year and explain correlations between indicators of the same group, such as income and illiteracy; and diachronic, in order to assess and correlate the temporal evolution of different indicators in the same group and the same indicator for the different groups. On a more general level, it is considered that the characteristics of the developed methodology make its use possible to evaluate existing socioeconomic differences among population clusters that transcend municipal division designed according to criteria of different natures.

Eğitim felsefesi; eğitimin en temel ilkelerini, kavramlarını, sorunlarını anlamaya çalışan felsefe alanı. Eğitim felsefesine dayalı olarak eğitimi tasarlamak eğitimde bir sistem kurmaktır. Felsefe teriminin kavramsal anlamı, bilindiği üzere, bilgelik sevgisidir. Bilgelik, derin düşünmektir/tefekkür etmektir. “Tefekkür, teşekkür etmektir”. Derin düşünmek en temel ilkeleri ortaya koymaktır. Bilgelik sevgisindeki sevmek, iki anlama gelir. Birincisi bilgi geçişi, sevgi ortamında vuku bulur. İkincisi, sevmek, yargıları mantığın süzgecinden geçirmektir. Grekler, hikmeti mantığın süzgecinden geçirerek felsefeyi yapmışlardır.
Bu araştırmada, eğitimin gerçekleştirmek istediği, öğrenme ve öğretmenin mahiyetini anlamaya çalışacağız. Öğrenme nasıl vuku bulur? İnsan nasıl öğrenir? Filozoflar, düşünürler, tarihte, öğrenmeyi ve öğretmeyi nasıl anlamışlar? Bütüncül bir yaklaşım ile eğitimi anlamaya çalışacağız.

La negociación colectiva en Francia
Authors: Urteaga Eguzki
Published: April 2020

El análisis de la negociación colectiva en Francia sugiere la existencia de un modelo propio que combina varias características: la pluralidad de los actores, la multiplicidad de los niveles, la indeterminación a priori de los objetos de negociación, el rol fundamental del Estado para garantizarla, estimularla y orientar su contenido, el vínculo persistente con la conflictividad en las empresas. A pesar de los avances realizados y de los importantes cambios acontecidos en los procesos y en lo que está en juego en la negociación, esta última no tiene ni la autonomía, ni la autoridad de la que dispone en numerosos países europeos. Este modelo incluye también toda una construcción jurídica destinada a reducir las contradicciones y tensiones que genera la diversidad de las fuentes de regulación: nociones de orden público social, de jerarquía de las normas, de “principio de favor” o de derogación bajo condiciones. Esta construcción es incierta, contingente, a veces contradictoria y tiene dificultades para encauzar y ordenar la multiplicidad de las prácticas de negociación. Conviene igualmente subrayar la importancia de los dispositivos que institucionalizan la negociación colectiva y dan cierta consistencia y estabilidad a las reglas que intervienen en la negociación.

Morinda citrifolia L. is a valuable medicinal plant, used to treat many diseases, such as sleeplessness, backache, high blood pressure... To study the shoot morphogenesis in Morinda citrifolia L. for propagation in the future, we examined the effects of BA, Zeatin and NAA on adventitious shoot formation of hypocotyl. The results showed that the regeneration of adventitious shoot comprised three steps of morphogenesis. In this process, Zeatin 1mg/l stimulated the formation of shoot primordia in dark (after a week), earlier than BA at the same concentration. Shoot generation was slow (after five weeks) on MS medium supplemented with 0,1mg/l and Zeatin 1mg/l. Roles of respiration rate and endogenous hormones were discussed to understand the physiological changes in the adventitious root formation.

APPROACH FOR FORECASTING DANGEROUS SEEPAGE AREA ON THE DAM SLOPE AFFECTED BY THE TIDE
Authors: Le Duc Van
Published: April 2020

Amplitude of osillation of water table surface and hydraulic gradient under tidal effect, tend to decrease while the seepage flow enters the earthen dam. Therefore, there exists a Dangerous Seepage Triangular Area (DSTA) where hydraulic gradient obtains maximum values. Based on the continuity equation and an assumption on the transmission of seepage oscillation, this DSTA can be specified. Finite Difference Method (FDM), analytical and DSTA methods were programmed using EXCEL software for computation and evaluation of simulated results. The numerical experiments show that the error of total seepage discharge during a tidal cycle between FDM and DSTA methods is less than 1.3%; and the error of maximum hydraulic gradient is not greater than 12%. Besides, the analysis on the earth dam slope stability shows that the most dangerous seepage case occurs when the minimum tidal water level exists as well as maximum hydraulic gradient of out-seepage flow is reached. This is one of the important reasons that explain plenty of tidal river bank erosions in Mekong River Delta.

Concentration in the banking sector and housing lending in Russian regions
Authors: Mishura Anna V. , Bekareva Svetlana V. , Meltenisova Ekaterina N.
Published: April 2020

The article examines the global and Russian experience in analyzing the influence of concentration and competition on the functioning of the banking sector, including the mortgage market. The information on housing loans issued by banks in the regions of Russia is used and the level of concentration in the regional housing lending markets is estimated. It is shown that regional housing loan markets are highly concentrated. It has been revealed that the concentration level negatively affects the dynamics of housing lending in the regions of the country. High concentration is also associated with slightly higher lending interest rates and their smaller spread. This may be the evidence that high concentration hinders the development of lending in the regions of Russia, which means that the level of competition in the banking sector is insufficient.
How does inflation influence income inequality in Russia?
Authors: Kartaev Philipp S. , Klachkova Olga A. , Lukianova Anna S.
Published: April 2020

The paper studies the impact of inflation on income inequality in Russian regions. It was revealed that the reduction in inflation from double-digit rate to the Bank of Russia’s target did not help to mitigate inequality, but rather exacerbated it. We identified a group of products which changing price dynamics affects inequality. The price increase may lead to the decline in inequality through redistributive effect. It is shown that in Russia this effect is associated with the channel of unexpected inflation that results in real wealth transfer from more prosperous lenders to less well-off borrowers. The policy of inflation targeting, successfully implemented by the monetary authorities in recent years, has reduced the volatility of inflation and limited the operation of this channel. At the same time, quantitative estimates of the increase in inequality as a result of achieving price stability remain relatively low.
Piketty’s team on inequality in Russia: A collection of statistical artifacts
Authors: Kapeliushnikov Rostislav I.
Published: April 2020

The paper provides a critical assessment of an authoritative study “From Soviets to oligarchs” (2017) on evolution of economic inequality in Russia by F. Novokmet, T. Piketty and G. Zucman where Russia is portrayed as a country with abnormally polarized income distribution by international standards. The author examines main quantitative results obtained by Piketty’s team, describes peculiar methodological features of their measuring procedure and analyzes how they dissect available empirical data sets. A general conclusion is that the trio uses an unconventional methodology that does not allow to apply equivalence scales; their argument suffers from internal inconsistencies (different units of observation and different definitions of income are used); they misunderstand the nature of data that form a base for their calculations (simulated estimates are perceived as raw survey data, post-tax incomes as pretax ones, etc.); deduction and declaration coefficients that they impose on tax data are empirically improbable; their final estimates of income inequality for Russia are higher than empirically realistic ones approximately by one third (Gini coefficients 0.5—0.6 instead of 0.3—0.4 by other researchers).

Nonparametric Estimation for a Slope of a Replicated Linear Functional Relationship Model
Authors: Mohd Arif Azuraini , Zubairi Yong Zulina , Hussin Abdul Ghapor
Published: April 2020

In this paper, we propose a nonparametric method to estimate the slope of a replicated linear functional relationship model. The nonparametric method is a robust method in nature and does not affect when the observations have outliers. Additionally, the nonparametric method does not require the normality assumption. Using simulation studies, we compared the performance of the proposed nonparametric method with the traditional method using maximum likelihood estimation. It is found that without any outlier, the maximum likelihood estimation works well but when outliers exist in the data, our proposed nonparametric method gives a small mean square error, thus suggesting a better estimate.
Keywords: linear functional relationship model; nonparametric method; outliers

Extreme return for weekly and monthly series is generated by using block maxima method. Four-employed test permits us to spot non-stationarity in extreme movement. The Augmented Dickey-Fuller and Kwiatkowski Phillips Schmidt Shin (KPSS) test scanned the unit root and the stationarity, and Mann-Kendall and Spearman's test inspected the trend and correlation in the series. Our approach approximates global stock returns for weekly and monthly series market activity. We ﬁnd most of the extreme stock to be active in shift movement, and we have confirmed that the movement of extreme share return for the majority of the stock indices in the weekly and monthly interval is non-stationary. This testified statistical property in the series can be used as the first crucial appraisal when scrutinizing extreme share return for future research.

One of the most important sides of life is wildlife. There is growing research interest in monitoring wildlife. Line transect sampling is one of the techniques widely used for estimating the density of objects especially for animals and plants. In this research, a parametric estimator for estimation of the population abundance is developed. A new parametric model for perpendicular distances for detection function is utilised to develop the estimator. In this paper, the performance of the parametric model which was developed using a simulation study is presented. The detection function has non-increasing curve and a perfect probability at zero. Theoretically, the parametric model which has been developed is guar-anteed to satisfy the shoulder condition assumption. A simulation study is presented to validate the present model. Relative mean error (RME) and Relative Bias (RB) are used to compare the estimator with well-known existing estimators. The results of the simulation study are discussed, and the performance of the proposed model shows promising statistical properties which outperformed the existing models.

A Bieberbach group is defined to be a torsion free crystallographic group which is an extension of a free abelian lattice group by a finite point group. This paper aims to determine a mathematical representation of a Bieberbach group with quaternion point group of order eight. Such mathematical representation is the exterior square. Mathematical method from representation theory is used to find the exterior square of this group. The exterior square of this group is found to be nonabelian.

Published: April 2020

The H-statistic is a robust test statistic in comparing the equality of two and more than two independent groups. This statistic is one of a good alternative to the F-statistic in the analysis of variance (ANOVA). The F-statistic is good only when the distribution of data is normal with homogeneous variances. If there is a violation of at least one of these assumptions, it affects the Type I error rate of the test. The main weakness of the F-statistic is its calculation based on the mean. The mean is well-known as a very sensitive central tendency measure with 0 breakdown point, whereas the H-statistic provides a test with fewer assumptions yet powerful. This statistic is readily adaptable to any measure of central tendency, and it appears to give reasonably good results. Hence, this paper provides a detailed study on the robustness of the H-statistic and its performance using different robust central tendency measures such that the modified one-step M (MOM) estimator and Winsorized MOM estimator. Based on the simulation study, this paper also investigates the performance of the H-statistic under various data conditions. The findings reveal that this statistic performs as well as the F-statistic under normal and homogeneous variance, yet it provides better control of Type I error rate under non-normal data or heterogeneous variances or both.

Forecasting stock market has been the centre of attraction among investors for a long period of time. Investors are always forecasting their return on investment in the stock market before they start to invest. In this study, to forecast on the stock market price, the monthly closing stock prices data from the Malaysian stock markets, namely AM001 Berhad, CI002 Berhad, HL003 Berhad and PB004 Berhad from 2008 to 2017, are examined for predictability results using Double Exponential Smoothing (DES) for Holt’s method and Artificial Neural Network (ANN). The data is partitioned into two parts due to different purposes.A sample data consisting of 96 months data from 2008 to 2015 was used for the estimation parameter and modeling part. Meanwhile, the evaluation part to validate the DES for Holt’s method and ANN was conducted using out-of-sample data involving 24 months data from 2016 to 2017. Three error measurements, MAD, MSE and RMSE, have been used in the evaluation to compare the performance of these two forecasting methods. The statistical analysis results show that Holt’s method is superior to ANN model and when using real values, it could accurately predict future price movements in the Malaysian stock markets. The outcomes from this study suggest that it is worthwhile to investigate the predictability and profitability of forecasting models.

Detection of Outliers in the Volatility of Malaysia Shariah Compliant Index Return: The Impulse Indicator Saturation Approach
Authors: Mohd Nasir Ida Normaya , Ismail Mohd Tahir
Published: April 2020

Financial time series data often affected by various unexpected events which known as the outliers. The aim of this study is to detect the outliers in high frequency data using Impulse Indicator Saturation approach (IIS).Monte Carlo simulations illustrate the ability of IIS to detect outliers by using data with various simulation settings. For empirical application, we have chosen the Malaysia Shariah compliant index which is the FBM EMAS Shariah (FBMS) index. The result of this study discovered the presence of 47 outliers which related to several global events such as global financial crisis (2008 & 2009), the falling of stock market (2011), the United States debt-ceiling crisis (2013) and the declination of international crude oil prices (2014).

Influence of Mannitol Priming on Maize Seeds Under Induced Water Stress
Authors: Dhakal P. , Subedi R.
Published: April 2020

Drought stress is seen as the major abiotic stress in the modern day agriculture and hinders crop germination and seedling establishment and maize suffers the problem more as a summer season crop. Priming is a physiological method to overcome such deleterious effect of water stress with the main aim of increasing the germination of seed. A lab experiment was therefore performed with maize seed priming using Mannitol @ 0%, 2%, 4%, 6% and 8% (w/v) concentrations subjected to germination under induced drought of 0 Mpa, 0.15 Mpa, 0.5 MPa, 1.0 MPa and 1.7 MPa using NaCl. The experiment was laid in completely randomized design (CRD) with three replications. Priming with mannitol reduced the Mean Germination Time (MGT); the best result obtained in seeds primed with 2% mannitol. However, the final germination count, Relative Water Content (RWC) and root and shoot length remained unaltered. Germination activities reduced with increasing moisture stress. The study indicated that priming with mannitol could improve the speed of germination in maize seeds.

Authors: Suadi Amran
Published: April 2020

This paper is motivated by the spirit of judicial reform in Indonesia in the reformation era. The right to access information on judicial institutions is an integral part of the constitutional rights that guaranteed by the Indonesian Constitution and must be fulfilled. The question proposed in this paper is how far the court decisions publication and judicial reform based on electronic courts implicated to increase public trust to judicial institutions in Indonesia? On the one hand, public information disclosure is a demand for democracy, transparency, and accountability of judicial institutions to gain the public trust. On the other hand, the level of public trust to the judicial institution is still low. The research objective is to provide a general description the judicial information system services based on electronic court through the Supreme Court Decisions Directory and its implication to increase the public trust to the judicial institutions in Indonesia. The results of this study indicate that the public can now easily access all court information ranging from case administration service procedures to issuing court decisions, which also has implications to increase the public trust to the judicial institutions itself. The evidence can be seen in the decision-making filing program in the last ten years, in which the Indonesian Supreme Court has also succeeded in publishing 4,661,021 court decisions, consisting of 4,403,428 at first-level court decisions, 123,995 at appellate court decisions, 100,863 at verdict decisions, and 32,735 at reconsi¬deration decisions.
