Authors: Dhar Pranab Kumar , Hazra Pulak , Shimamura Tetsuya
Published: March 2020

Digital watermarking has been utilized effectively for copyright protection of multimedia contents. This paper suggests a blind symmetric watermarking algorithm using fan beam transform (FBT) and QR decomposition (QRD) for color images. At first, the original image is transferred from RGB to L*a*b* color model and FBT is applied to b* component. Then the b*component of the original image is split into m × m non-overlapping blocks and QRD is conducted to each block. Watermark data is placed into the selected coefficient of the upper triangular matrix using a new embedding function. Simulation results suggest that the presented algorithm is extremely robust against numerous attacks, and also yields watermarked images with high quality. Furthermore, it represents more excellent performance compared with the recent state-of-the-art algorithms for robustness and imperceptibility. The normalized correlation (NC) of the proposed algorithm varies from 0.8252 to 1, the peak signal-to-noise ratio (PSNR) varies from 54.1854 to 54.1892, and structural similarity (SSIM) varies from 0.9285 to 0.9696, respectively. In contrast, the NC of the recent state-of-the-art algorithms varies from 0.5193 to 1, PSNR varies from 38.5471 to 52.64, and SSIM varies from 0.9311 to 0.9663, respectively.

Published: March 2020

In this article, the magnetohydrodynamic (MHD) flow of Casson nanofluid with thermal radiation over an unsteady shrinking surface is investigated. The equation of momentum is derived from the Navier–Stokes model for non-Newtonian fluid where components of the viscous terms are symmetric. The effect of Stefan blowing with partial slip conditions of velocity, concentration, and temperature on the velocity, concentration, and temperature distributions is also taken into account. The modeled equations of partial differential equations (PDEs) are transformed into the equivalent boundary value problems (BVPs) of ordinary differential equations (ODEs) by employing similarity transformations. These similarity transformations can be obtained by using symmetry analysis. The resultant BVPs are reduced into initial value problems (IVPs) by using the shooting method and then solved by using the fourth-order Runge–Kutta (RK) technique. The numerical results reveal that dual solutions exist in some ranges of different physical parameters such as unsteadiness and suction/injection parameters. The thickness of the velocity boundary layer is enhanced in the second solution by increasing the magnetic and velocity slip factor effect in the boundary layer. Increment in the Prandtl number and Brownian motion parameter is caused by a reduction of the thickness of the thermal boundary layer and temperature. Moreover, stability analysis performed by employing the three-stage Lobatto IIIA formula in the BVP4C solver with the help of MATLAB software reveals that only the first solution is stable and physically realizable.

Published: March 2020

Marek’s disease virus (MDV), an alpha herpes virus, causes a lymphoproliferative state in chickens known as Marek’s disease (MD), resulting in severe monetary losses to the poultry industry. Because lymphocytes of bursa of Fabricius and spleen are prime targets of MDV replication during the early cytolytic phase of infection, the immune response in bursa and spleen should be the foundation of late immunity induced by MDV. However, the mechanism of the MDV-mediated host immune response in lymphocytes in the early stage is poorly understood. The present study is primarily aimed at identifying the crucial genes and significant pathways involved in the immune response of chickens infected with MDV CVI988 and the very virulent RB1B (vvRB1B) strains. Using the RNA sequencing approach, we analyzed the generated transcriptomes from lymphocytes isolated from chicken bursa and spleen. Our findings validated the expression of previously characterized genes; however, they also revealed the expression of novel genes during the MDV-mediated immune response. The results showed that after challenge with CVI988 or vvRB1B strains, 634 and 313 differentially expressed genes (DEGs) were identified in splenic lymphocytes, respectively. However, 58 and 47 DEGs were observed in bursal lymphocytes infected with CVI988 and vvRB1B strains, respectively. Following MDV CVI988 or vvRB1B challenge, the bursal lymphocytes displayed changes in IL-6 and IL-4 gene expression. Surprisingly, splenic lymphocytes exhibited an overwhelming alteration in the expression of cytokines and cytokine receptors involved in immune response signaling. On the other hand, there was no distinct trend between infection with CVI988 and vvRB1B and the expression of cytokines and chemokines, such as IL-10, IFN-γ, STAT1, IRF1, CCL19, and CCL26. However, the expression profiles of IL-1β, IL-6, IL8L1, CCL4 (GGCL1), and CCL5 were significantly upregulated in splenic lymphocytes from chickens infected with CVI988 compared with those of chickens infected with vvRB1B. Because these cytokines and chemokines are considered to be associated with B cell activation and antigenic signal transduction to T cells, they may indicate differences of immune responses initiated by vaccinal and virulent strains during the early phase of infection. Collectively, our study provides valuable data on the transcriptional landscape using high-throughput sequencing to understand the different mechanism between vaccine-mediated protection and pathogenesis of virulent MDV in vivo.
Genetic Strain Diversity of Multi-Host RNA Viruses that Infect a Wide Range of Pollinators and Associates is Shaped by Geographic Origins

Published: March 2020

Emerging viruses have caused concerns about pollinator population declines, as multi-host RNA viruses may pose a health threat to pollinators and associated arthropods. In order to understand the ecology and impact these viruses have, we studied their host range and determined to what extent host and spatial variation affect strain diversity. Firstly, we used RT-PCR to screen pollinators and associates, including honey bees (Apis mellifera) and invasive Argentine ants (Linepithema humile), for virus presence and replication. We tested for the black queen cell virus (BQCV), deformed wing virus (DWV), and Kashmir bee virus (KBV) that were initially detected in bees, and the two recently discovered Linepithema humile bunya-like virus 1 (LhuBLV1) and Moku virus (MKV). DWV, KBV, and MKV were detected and replicated in a wide range of hosts and commonly co-infected hymenopterans. Secondly, we placed KBV and DWV in a global phylogeny with sequences from various countries and hosts to determine the association of geographic origin and host with shared ancestry. Both phylogenies showed strong geographic rather than host-specific clustering, suggesting frequent inter-species virus transmission. Transmission routes between hosts are largely unknown. Nonetheless, avoiding the introduction of non-native species and diseased pollinators appears important to limit spill overs and disease emergence.

Leishmania infantum parasites cause a severe form of visceral leishmaniasis in human and viscerocutaneous leishmaniasis in dogs. Recently, we reported that immunization with an attenuated L. infantum cell line, lacking the hsp70-II gene, protects against the development of murine cutaneous leishmaniasis. In this work, we analyzed the vaccine potential of this cell line towards the long-term protection against murine visceral leishmaniasis. This model shows an organ-dependent evolution of the disease. The infection can resolve in the liver but chronically affect spleen and bone marrow. Twelve weeks after subcutaneous administration of attenuated L. infantum, Bagg Albino (BALB/c) mice were challenged with infective L. infantum parasites expressing the luciferase-encoding gene. Combining in vivo bioimaging techniques with limiting dilution experiments, we report that, in the initial phase of the disease, vaccinated animals presented lower parasite loads than unvaccinated animals. A reduction of the severity of liver damage was also detected. Protection was associated with the induction of rapid parasite-specific IFN-γ production by CD4+ and CD8+ T cells. However, the vaccine was unable to control the chronic phase of the disease, since we did not find differences in the parasite burdens nor in the immune response at that time point.
Econometric Study of the Dynamics of Foreign Direct Investment in Russia

Published: March 2020

Foreign investment is of high importance for economic growth in Russia. The problem of enhancing investment flows makes it increasingly relevant to search for effective tools for stimulating investment activity. We attempt to identify the factors affecting the dynamics of foreign direct investment (FDI). The paper analyses the current state of foreign direct investment in the Russian economy. Using empirical data for 2001–2018, we construct an econometric model for Russia which considers such factors as inflation (the Consumer Price Index), the exchange rate and imports. The results of the model’s testing do not confirm the initial assumptions that inflation exerts a more profound effect on FDI than the exchange rate and that there is a correlation between these indicators. For Russia, the dependence of FDI on the exchange rate remains insignificant; in addition, we find a direct relationship between the indicators. According to the model, the impact of inflation (direct relationship) and the volume of imports (inverse relationship) are of greater significance. It is noteworthy that the dynamics of foreign direct investment is partially due to its fluctuations with a time lag. The model forecasts that from 2019 to 2024 Russia is expected to experience a rise in FDI net outflows. The findings indicate that in order to attract foreign direct investment, it is necessary to implement economic transformations that will improve the business environment and lead to the development of healthy competition.

The problems of organizing effective management accounting of agricultural production through the widespread use of economic methods, both production management and accounting and management methods and the development of their information functions, are very relevant and necessary. Management accounting in modern times is a universal integrated mechanism for the accounting and management activities of an agricultural organization. The management accounting information system should be oriented towards solving complex issues and making managerial decisions quickly. The purpose of the study is the rationale for rationing, planning and management accounting of costs, their control and analysis of production results in the agricultural management information system. The subject of the study is management accounting, while principles are formulated and new methods for rationing labor, material and biological costs of agricultural production are proposed. A unified nomenclature of cost items has been developed for planning, managerial accounting, analysis and control, both for individual production, accounting and planning objects, as well as for self-supporting units (responsibility centers) and the organization as a whole. For the organization of rationing, planning and management accounting of production costs, the sequence of implementation of special procedures is defined, a unified nomenclature of cost items is developed based on the basic conditions of requirements, which include classification attributes, degree of cost participation in the creation of new products, cost control by hierarchical levels of management. It is concluded that by comparing the actual and planned costs for the production of a particular object of planning and accounting, it is possible to analyze their cause and effect deviations, deviations of the actual marginal income and operating profit of the production of these products from their normative values ​​by changing each specific cost item.

The article focuses on the need to respect human rights in the provision of medical services in Ukraine. It is strictly unacceptable to restrict citizens of Ukraine in receiving free medical services, since such a right is provided for by Art. 49 of the Constitution of Ukraine. It is proposed to consider that a medical service includes all types of medical care and is a special activity in relation to human health. The concept and main signs of medical services are revealed, it is established that the state, local governments, legal entities and individuals, including the patient, can be the customer of medical services. Ukrainian legislation governing the provision of medical services does not meet international standards. The positive experience of the EU countries (France, Denmark, Slovakia) and the world (Australia, Canada) shows that access to medical services is provided within the framework of medical insurance, in most cases free of charge, and is controlled by authorized state organizations.
The purpose of the article is to determine the content, signs of medical services, classification criteria for their subjects, disclose the features of their legal regulation, clarify the problems of legalization of medical services and improve legislation taking into account foreign experience. The research methodology is based on a systematic approach, which is determined by the specifics of the topic of the article, and is also associated with the use of general and special research methods. The comparative legal method and the method of legal analysis were used in the study of legislative rules governing the provision of medical services. Using the method of legal analysis, groups of subjects of medical legal relations in the field of medical services are determined and their powers are analyzed. The formal logical method was used to differentiate the criteria for distinguishing between the legal structures “medical care” and “medical service”. The results of the study contributed to the identification of certain legal problems that arise when citizens receive medical services and require immediate resolution. It is also advisable to introduce compulsory state health insurance.

Authors: Isakov M. M.
Published: March 2020

This study describes development of a multiplex PCR assay for detection of BHV-1, BVDV, Chlamydia spp. and Mycoplasma spp. infections in bovines. The assay was developed using genomic DNA and RNA and four sets of PCR primers targeting 16S rRNA genes of Chlamydia spp., Mycoplasma spp., 5’-UTR of Bovine viral diarrhea virus, gE of Bovine herpesvirus-1, respectively. A total of 100 tissue samples were collected from cattle suspected to be infected with the viral and bacterial pathogens (BVDV, BHV-1, Chlamydia spp. and Mycoplasma spp.) from different regions of Ukraine. A part of sample was stored at –50°C for isolation of genomic DNA and RNA. The multiplex PCR assay was optimized in the study. The specific primers designed and used in the study were found sensitive and specific in amplifying target genes viz. 16S rRNA, gE, 5’-UTR of Chlamydia spp., Mycoplasma spp., BHV-1 and BVDV, respectively. The PCR primers used in the optimization of multiplex PCR assay for detection of Bovine viral diarrhea virus, Bovine herpesvirus-1, Chlamydia spp., Mycolasma spp. could amplify 221 bp, 111 bp, 386 bp, 279 bp products, respectively. Non specific amplification was not observed

The first and the main link in the system of prevention of the occurrence and distribution of avian influenza and Newcastle disease is monitoring and the effective prophylaxis of the above diseases. At the same time the conducting of disinfection of the objects of veterinary control is an important stage in the system of veterinary and sanitary measures. A number of disinfectants that contain different classes of chemical compounds as active substances have been developed and proposed for practical use. The large-scale production of disinfectants and their introduction into practice is impossible without the preliminary laboratory assessment of their antimicrobial properties, the determination of the spectrum of their biocidal effect and physical, chemical and toxicological properties. The aim of our work was to study the virucidal properties of a new aldehyde disinfectant using the test models of the viruses of Newcastle disease and avian influenza. The experiments to study virucidal properties of the disinfectant regarding the viruses of avian influenza and Newcastle disease have been carried out at the Department for Avian Diseases Study of the National Scientific Center ‘Institute of Experimental and Clinical Veterinary Medicine’ in accordance with the guidelines ‘Methods for determining and evaluating the safety and quality of disinfectants and disinfecting detergents used in the production, storage, transportation and sale of products of animal origin’ (Kotsiumbas et al., 2010). The determination of the virucidal properties of the disinfectant has been conducted in two stages: stage 1 — the determination of the virucidal activity of the product by the suspension method; stage 2 — determination of the virucidal activity of the product on test objects. As a result of the research conducted by the suspension method the presence of the virucidal properties of the innovative disinfectant (the mixture of quaternary ammonium compounds — 25%, glutar aldehyde — 11%, isopropanol, non-ionic surfactants) for the viruses of avian influenza and Newcastle disease has been determined. It has been found that the above preparation completely inactivated the infective properties of viruses when used in the concentration of 0.1%, with the interval of 30 minutes and in the concentration of 0.5% — 15-minute interval. It has been proved that the use of the disinfectant in 0.1% concentration for 30 minutes disinfected the test objects (wood, metal, tile, textile) that were contaminated by the pathogenic agents of avian influenza and Newcastle disease
Comparação de leituras de turbidez com diferentes equipamentos: contribuições à regulamentação brasileira de qualidade da água para consumo humano
Authors: Candian Ferreira Larissa , Kopschitz Xavier Bastos Rafael
Published: March 2020

Foram avaliadas a confiabilidade analítica e as diferenças entre leituras de turbidez de amostras de água bruta, decantada e filtrada, obtidas com quatro turbidímetros portáteis de duas marcas, seis equipamentos online de duas marcas e um turbidímeto de bancada. Apesar de diferenças terem sido observadas tanto entre equipamentos como entre operadores, por vezes estatisticamente significativas, estas foram de pequena magnitude, de tal forma que não comprometeriam a interpretação do atendimento / violação dos limites de 0,50 uT e 0,30uT estabelecidos na norma brasileira de qualidade da água para consumo humano. Sugere-se, portanto, que o padrão de turbidez de água filtrada pode ser verificado independentemente do tipo de equipamento utilizado.
A Note on Differential Identities in Prime and Semiprime Rings

Published: March 2020

Let R be a prime ring, I a nonzero ideal of R, d a derivation of R and m, n fixed positive integers. (i) If (d ( r ○ s)(r ○ s) + ( r ○ s) d ( r ○ s)n - d ( r ○ s))m for all r, s ϵ I, then R is commutative. (ii) If (d ( r ○ s)( r ○ s) + ( r ○ s) d ( r ○ s)n - d (r ○ s))m ϵ Z(R) for all r, s ϵ I, then R satisfies s4, the standard identity in four variables. Moreover, we also examine the case when R is a semiprime ring.
Minimize Project Risk and Costs: A New Approach to Project Management
Authors: Rivera Alfredo , Kashiwagi Dean
Published: March 2020

Traditional project management (PM) results have been poor. The practices of direction and control have been identified by deductive logic as problematic. Deductive logic identifies that, if a manager directs and controls, their risk goes up and performance will go down. A new approach to PM is the replacement of technical expertise with the identification and utilization of expertise. New components of this approach are the minimization of the need to think and make decisions, the use of the language of metrics, a new definition of risk, and the use of preplanning that includes the utilization of expertise and focusing on the mitigation of risk that the expert does not control. This approach has been tested by the International Council for Research and Innovation in Building and Construction Working Commission (CIB W117, formerly known as the Performance Based Studies Research Group at Arizona State University) for the past 25 years increasing customer satisfaction to 98% and minimizing cost by 5 to 30%. These practices are a part of the “PM of the Future.”

Published: March 2020

In this paper we consider the deployment of mobile relay nodes in a Cooperative Non Orthogonal Multiple Access (CNOMA) system with variable gain Amplify and Forward relaying. In a multiuser downlink scenario, two users are chosen as the NOMA destination pairs based on the channel quality and another suitable user is chosen to act as the relay node. Two standard relay selection protocols are examined here viz. the partial relay selection (PRS) and optimal relay selection (ORS). An outdated channel condition induced by the user mobility condition is considered in this paper and the impact of channel correlation on the system performance is analyzed. The outage performance and ergodic sum rate capacity of the users is observed under the two relay selection schemes. Further, the impact of user node velocity on the relay selection and outage performance have been reported. It is observed that the optimal relay selection has an overall better performance compared to partial relay selection. However, the impact of user velocity and time delay is lesser in case of partial relay selection. Hence, partial relay selection method has a more stable performance in case of imperfect CSI compared to optimal relay selection.
Existence of a Bilinear Differential Realization in the Constructions of Tensor Product of Hilbert Spaces

Published: March 2020

The paper describes the results of a functional-geometric study of the necessary and sufficient conditions for the existence of a differential realization in the terms of the tensor product of real Hilbert spaces. There are considered continuous infinite-dimensional dynamical system in the class of controlled bilinear nonstationary ordinary differential equations of the second order (including quasi-linear hyperbolic models) in a separable Hilbert space. Therefore the topological and metric conditions for the continuity of the RayleighRitz operator with the calculation of the fundamental group of its image are analytically substantiated. The results of paper give incentives for generalizations in the qualitative theory of nonlinear structural identification of higher order multi-linear differential models.
