Authors: Pyankov S. A , Ivanova E. V , Ternovoy V. A , Agafonov A. P
Published: April 2021

The aim of the study was in the differential specific diagnosis of viral infections of unknown etiology in patients who have recently returned from a trip to the countries of Southeast Asia and India. In 2013, SRC VB "Vector" examined single serum samples from 131 patients with suspected Dengue Fever. Dengue viral RNA was detected by means of polymerase chain reaction, NS dengue virus antigen and antibody classes M and G to Dengue virus - with the use of immunochromatographic methods and enzyme immunoassay. In the same sera the presence of specific IgM to measles, rubella and cytomegalovirus virus antigen was revealed by enzyme immunoassay and enzyme-enhanced chemiluminescence. As a result of examination 87 (66.4%) ofsamples were diagnosed as "Dengue fever". In seven out of the 87 samples there were detected specific class-M antibodies to cytomegalovirus. 44 sera (33.6%) out of 131 did not contain markers for Dengue fever. But 4 out of them contained IgM to measles virus, the other 5 sera contained IgM to rubella virus. Regional Centre of WHO laboratory confirmed three cases of measles, the one positive result for the content of IgM to rubella virus antigens results was interpreted as "equivalent." Identified in 2013 cases of importation ofmeasles and rubella by tourists from Southeast Asia and India have not resulted in the transmission of the disease through contact with others persons in Russia. In seven detected Dengue Fever cases opportunistic cytomegalovirus infection was revealed.

Authors: Tyukavkina S. U , Kharseeva G. G
Published: April 2021

The problem of epidemiology, laboratory diagnosis and specific prophylaxis of pertussis remains to be relevant because the level of the morbidity rate of this infection ‘managed’ by vaccination is rising, despite the wide coverage of immunization of the child population. Knowledge of the distribution and the course ofpertussis infection, Bordetella pertussis strains circulating in modern conditions, factors of pathogenicity of the causative agent and mechanisms of pathogenesis of the disease is important as wellfor medical students as for physicians ofvarious specialties - not only pediatricians, but also therapeutists, pulmonologists, microbiologists, epidemiologists and etc. It is worth to consider principles of laboratory diagnosis of pertussis and difficulties to which the laboratory service is faced at this as well as the comparative characteristics of traditional and express methods for diagnosing of pertussis infection - possible and regulated for implementation by basic bacteriological labotories in the territory of Russian Federation. Fundamentals of pertussis vaccination as the only effective means for prevention of mass outbreaks of this disease are also considered in the framework of the proposed lecture.

Published: April 2021

Interferon-gamma (IFN-y) is a pleiotropic lymphokine that have multiple effects on the growth and differentiation of various types of cells associated with innate immunity. IFN-y induces differentiation ofmyeloid cells, stimulates the expression of major histocompatibility complex (MHC) class II and class I antigens, it is a potent activator of macrophages which destroy antigenic molecules penetrating the cell. IFN-y is widely used for the treatment of infectious diseases, cancer, autoimmune and allergic diseases. Studies conducted in Research Institute ofInfluenza indicate that drugs IFN-y can be successfully usedfor prevention of influenza and acute respiratory infection (ARI) during the rise of incidence, as well as for the treatment - the first few days/ hours of the onset. The concomitant use of drugs as IFN-a and IFN-y on influenza and ARI can greatly improve the prophylactic and therapeutic efficacy.

Published: April 2021

As a result of the application of experimental test systems "ELISA-IgM-dengue", "ELISA-IgM-WN" and "ELISA-IgM-TBE" when examining sera from patients with dengue fever (DF), West Nile fever (WNF) and tick-borne encephalitis (TBE) there was established the possibility of a clear differential diagnosis of these related flavivirus infections. Application of the ELISA-IgG test systems fail to provide such an opportunity due to cause of pronounced cross-reactions of group-IgG antibodies. In the article there are presented data on dynamics of IgM and IgG antibodies in patients with dengue fever. Detection of specific IgG in the first days of the disease may indicate to a secondary nature of infection and the possibility of the development of hemorrhagic syndrome.

The epidemiological situation for HIV infection in Russia remains to be extremely stringent, which requires a search for new, more efficient and cost-effective solutions aimed at countering the epidemic. The inclusion of laboratory studies with the use of a test system for the determination of the remoteness of HIV infection in routine surveillance practices will permit to determine the frequency of occurrence of early cases of infections among newly diagnosed HIV-positive persons. The analysis of this criterion at the population level will help to objectively evaluate the effectiveness of prevention, control activities carried out in a particular area. The increase of objectivity in the determination of the time elapsed from the moment of infection of HIV-1 with the use of the test system DSEIA-HIV-Ab-TERM provides the opportunity to use the obtained results in the epidemiological investigation for the purpose of more accurate and complete identification of contact persons. The determination of the probable period of infection may also be required in the solving the question on the prescription of antiretroviral therapy as a complementary study in the monitoring of HIV drug resistance. The aim of this work was to determine the effectiveness of the new test system DS-EIAHIV-Ab-TERM for the determination of the likely timing of HIV-1 infection. There were studied serum samples (plasma) of blood of HIV-infected persons with epidemiologically established time of infection (n = 281) and samples of commercial seroconversion panels. Results of the performed study showed that the probability of a correct detection of the remoteness of HIV-1 infection for samples from individuals with the most probable time of the established fact of infection was 95%, for samples of commercial seroconversion panels - 100%. The data demonstrated the high efficacy of the test system DS-“EIAHIV-Ab-TERM” in the determination of the most probable timing of infection with human immunodeficiency virus type 1, that in combination with the speed and simplicity of the procedure allows to recommend it for use in the laboratory practice.

Lethal cases of tick-borne encephalitis in previously vaccinated patients have not been described. Modern inactivated vaccines against Tick-borne encephalitis (TBE) are high effective. The TBE cases, preference unfocal forms, are developed in persons with incomplete irregular vaccination. First case of lethal TBE after plural vaccination was described in the Kurgan region, the second case - in the Chelyabinsk region. These very rare unusual cases were studied. Being dominant the Siberian subtype of TBE virus is related with lethal TBE cases in the Chelyabinsk region. Unusual TBE case was developed in patient who had been vaccinated 8 limes with vaccines produced from strains of Far-Eastern TBE subtype («Virion», Tomsk, Chumakov institute, Moscow) and European TBE subtype (Encepur; FSME-Immun). Two years after the last vaccination a focal form of TBE was developed with lethal outcome at 9 th day. Specific antibodies IgM and IgG seroconversion were detected. The TBE virus antigen was detected in brain neurons by immunofluorescent test. Destructed neurons and gliocyles were shown by hystological study in cerebral hemispheres and cerebellum. The Purkinje cells were destructed. Possible reasons of surmounting vaccinal immunity including a genetic difference of vaccine and infection virus strains are discussed.

Published: April 2021

In the article there are presented the data of own investigations of changes of antiendotoxic humoral immunity in some infections of bacterial and viral origin - intestinal infections (rotaviral infection, localized forms of salmonellosis, gastroenteritis caused by opportunistic flora) and influenza A. The levels of antibodies to the lipopolysaccharide of Escherichia coli K235 (Sigma Chem. Co., USA) were determined in the serum of 81 patients with acute intestinal moderate infections and in the serum of 62 patients with influenza A /H1N1/California/09/ in various periods of the disease with the use of ELISA method. Studied immunoglobulin M was revealed to rise significantly in diseases of viral and bacterial etiology. More pronounced evidence of such changes of humoral antiendotoxic immunity was observed in acute infectious pathology proceeding with the involvement of the intestine. Obtained by ourselves data may attest to the stimulation of antiendotoxic immunity in the initial period of influenza and compensateness for this process in uncomplicated forms of the disease. The pronounced change in indices of humoral antiendotoxic immunity in cases of bacterial, viral-bacterial disease usually indicated to a more severe or complicated form of the disease. The performed study emphasizes the important role of various viral and bacterial associations and the ability of these associations to the system rather than the local pathogenetic impact on the human organism, in particular on the system of antiendotoxic immunity.

Germany has a long history in seismic instrumentation. The installation of the first station sites was initiated in those regions with seismic activity. Later on, with an increasing need for seismic hazard assessment, seismological state services were established over the course of several decades, using heterogeneous technology. In parallel, scientific research and international cooperation projects triggered the establishment of institutional and nationwide networks and arrays also focusing on topics other than monitoring local or regional areas, such as recording global seismicity or verification of the compliance with the Comprehensive Nuclear-Test-Ban Treaty. At each of the observatories and data centers, an extensive analysis of the recordings is performed providing high-level data products, for example, earthquake catalogs, as a base for supporting state or federal authorities, to inform the public on topics related to seismology, and for information transfer to international institutions. These data products are usually also accessible at websites of the responsible organizations. The establishment of the European Integrated Data Archive (EIDA) led to a consolidation of existing waveform data exchange mechanisms and their definition as standards in Europe, along with a harmonization of the applied data quality assurance procedures. In Germany, the German Regional Seismic Network as national backbone network and the state networks of Saxony, Saxony-Anhalt, Thuringia, and Bavaria spearheaded the national contributions to EIDA. The benefits of EIDA are attracting additional state and university networks, which are about to join the EIDA community now.
Monitoring Icequakes in East Antarctica with the Raspberry Shake
Authors: Winter Kate , Lombardi Denis , Diaz-Moreno Alejandro , Bainbridge Rupert
Published: April 2021

We evaluate the performance of the low-cost seismic sensor Raspberry Shake (RS) to identify and monitor icequakes (which occur when glacial ice experiences brittle deformation) in extreme environments. In January 2020, three RS3D sensors were installed on a katabatic wind-scoured blue ice area (BIA) close to the Princess Elisabeth Antarctica research station in Dronning Maud Land, East Antarctica. The sensors were configured for Antarctic deployment and placed in insulated enclosures to protect them from harsh weather systems. The RS network (installed in a triangular array) performed well in the cold and with rapid air temperature change, as diurnal temperatures fluctuated from a high of 0.0°C to a minimum temperature of −15.0°C. Although battery connectivity issues in one unit limit full triangulation of seismic signals, and high background noise may mask some seismic signals, data from the RS2 unit reveals that 2936 icequakes were detected over a 10-day period. The temporal occurrence of these icequakes, combined with satellite-derived surface temperature measurements and automatic weather station data, suggest that diurnal fluctuations in solar radiation control ice surface temperature changes, driving thermal contraction of the ice. Seismic investigations like these can therefore provide information on the thermal state and ice fracture mechanics of ablation zones such as BIAs. Our work highlights the potential application of the RS (after minimal modification) in glaciated environments where equipment often needs to be portable, temporary and lightweight, and able to perform in extreme weather conditions.

The Antarctic Seismographic Argentinean Italian Network (ASAIN) is a permanent broadband seismic network that has operated since 1995 in the Scotia Sea region, the Antarctic peninsula, and the polar area. It was deployed and is managed in the framework of cooperation between the National Institute of Oceanography and Applied Geophysics and Dirección Nacional del Antártico–Instituto Antártico Argentino and is financially supported by the Programma Nazionale di Ricerca in Antartide. The network consists of seven seismological stations with broadband sensors. ASAIN provides data to Incorporated Research Institutions for Seismology, Observatories and Research Facilities for European Seismology, and GEOFOrschungsNetz. It improves the worldwide seismic networks’ detection capabilities and contributes to refining regional earthquake locations released by the U.S. Geological Survey. The proximity of the seismic stations to the Antarctic continent and their continuous operation in the long term also allows for having a privileged observatory on the ice-related seismicity along the Antarctica peninsula.

In this article, we discuss the historical development of ASAIN, its current configuration, and the main characteristics of the seismic stations. Finally, we also provide information on the ASAIN data exchange and the contribution to the scientific research in Antarctica.

Published: April 2021

The purpose of the article is to theoretically substantiate the concept of a graduate’s satisfaction profile with educational programs, which includes a number of parameters. This concept is proposed to be introduced in connection with monitoring the satisfaction of university graduates with educational programs. The methodology for measuring graduate satisfaction is based on the use of quantitative (questionnaires, the results of which are processed in SPSS) and qualitative (interviewing) methods. Graduates’ satisfaction with the quality of higher education is considered as a subjective assessment of the quality of their education. The proposed and tested methodology can become the basis for the development of a university system for monitoring the satisfaction of university graduates with educational programs and a university quality management system.

Para compreender as cidades, é necessário entender o espaço, suas relações interpessoais, os fluxos entre o rural e urbano, além das dinâmicas ambientais presentes. Estes pontos de análise do espaço urbano são importantes, pois neles se concentram a produção social e a intervenção no meio. A dinâmica estabelecida na ocupação do urbano proporciona alguns elementos que precisam ser estudados, como as condições em saúde, perfil socioeconômico entre outros. Outra perspectiva a ser analisada é a levantada por Schor (2013 p.70), sobre a temática da saúde pública, elemento importante para se compreender a dinâmica urbana da cidade e do município, pois é na cidade que se encontram todos os fixos relacionados à saúde. Nesta perspectiva, esse estudo busca a compreensão espacial, além da relação entre ambiente e saúde. Para isso, será aplicada a Análise Espacial, uma técnica do Geoprocessamento. O Geoprocessamento auxilia em diversos pontos, tais como o processamento de dados e imagens de satélite. A análise espacial permite diferentes formas de avaliar os dados, ambientais e socioeconômicos que, através de um conjunto de procedimento encadeados, cuja finalidade é a escolha de um modelo inferencial, considera explicitamente os relacionamentos espaciais presente no fenômeno (CÂMARA G. et al, 2004, p. 3).

Human Computer Interaction (HCI) focuses on the interaction between humans and machines. An extensive list of applications exists for hand gesture recognition techniques, major candidates for HCI. The list covers various fields, one of which is sign language recognition. In this field, however, high accuracy and robustness are both needed; both present a major challenge. In addition, feature extraction from hand gesture images is a tough task because of the many parameters associated with them. This paper proposes an approach based on a bag-of-words (BoW) model for automatic recognition of American Sign Language (ASL) numbers. In this method, the first step is to obtain the set of representative vocabularies by applying a K-means clustering algorithm to a few randomly chosen images. Next, the vocabularies are used as bin centers for BoW histogram construction. The proposed histograms are shown to provide distinguishable features for classification of ASL numbers. For the purpose of classification, the K-nearest neighbors (kNN) classifier is employed utilizing the BoW histogram bin frequencies as features. For validation, very large experiments are done on two large ASL number-recognition datasets; the proposed method shows superior performance in classifying the numbers, achieving an F1 score of 99.92% in the Kaggle ASL numbers dataset.
The Effect of Financial Regulation on Reputation
Authors:   Dept. of Computer Science, University College London, Gower Street, London WC1E 6BT, UK, Mitic Peter
Published: April 2021

Recent high profile breaches of regulation by prominent UK financial institutions suggest that self-regulation is ineffective. Intuitively, regulatory breaches should result in a tarnished reputation, but that conjecture is unsubstantiated. With objective measurement of reputation, we demonstrate that reputational damage is not a significant deterrent against regulatory breaches. Imposing regulatory fines is also no deterrent. We speculate that customers are prepared to tolerate large regulatory breaches: retail customers provided they are not affected personally, and corporate customers as long as investments do not devalue. Regulation has not previously been linked to reputation, and this result is significant because it adds to the argument that external regulation remains necessary. Note is also made of recent unsuccessful initiatives on self-regulation.
Forecasting the United States Unemployment Rate by Using Recurrent Neural Networks with Google Trends Data
Authors:   Indian Institute of Technology Kharagpur, India, Kundu Sourav , Singhania Rajshekhar
Published: April 2021

We study the problem of obtaining an accurate forecast of the unemployment claims using online search data. The motivation for this study arises from the fact that there is a need for nowcasting or providing a reliable short-term estimate of the unemployment rate. The data regarding initial jobless claims are published by the US Department of labor weekly. To tackle the problem of getting an accurate forecast, we propose the use of the novel Long Short-Term Memory (LSTM) architecture of Recurrent Neural Networks, to predict the unemployment claims (initial jobless claims) using the Google Trends query share for certain keywords. We begin by analyzing the correlation of a large number of keywords belonging to different aspects of the economy with the US initial jobless claims data. We take 15-year weekly data from January 2004 to January 2019 and create two different models for analysis: a Vector Autoregressive Model (VAR) model combining the official unemployment claims series with the search trends for the keyword ‘job offers’ taken from Google Trends and an LSTM model with only the Google trends time series data for the complete set of identified keywords. Our analysis reveals that the LSTM model outperforms the VAR model by a significant margin in predicting the unemployment claims across different forecast horizons.
Can Momentum Be Explained by Fund Flows or Disposition Effect? The Impact of Behavioral Biases and Capital Flows in Brazilian Market Movements
Authors:   Catholic University of Leuven (KU Leuven), Belgium, Pitthan Francisco
Published: April 2021

Momentum is one of the most robust anomalies in financial markets, there are two main recent explanations for this phenomenon, a behavioral-based explanation through disposition-effect (i.e., the willingness to sell “winners” too quickly and to hold “losers” for a long time) and a fund-flow based explanation. The disposition-effect explanation is centered in the convergence of the spread between the fundamental value and the observed market price (disposition-effect causes an underreaction to news that generates this spread), and the fund flows-based explanation is due to the persistence of the performance of mutual-funds (which usually keep buying winning positions and selling the losses). This paper compares those theories using Brazilian data (which is suitable for the strong presence of momentum). The empirical analysis was done using Fama-MacBeth regressions with results pointing the disposition-effect explanation as the most significant, with the robustness analysis contributing positively to the main findings.

Before 1990, foreign investors could not extensively invest in Brazil because of its stringent and conservative trade policy. However, in 1990 Brazil took a remarkable shift in its trade policy from its previous trends by taking a liberal stance in terms of FDI inflow. The liberal trade policy that Brazil took in 1990 remove all the trade barriers that previously hindered the free flow of FDI in Brazil, the sign of which had been reflected in the steady and gradual incremental FDI inflow in the country after that. This New opening of trade atmosphere had brought with it two very different repercussions. In one hand, it accelerated the economic growth by bringing in investment in the needed sectors; on the other hand this acceleration spurred industrial activities that are accompanied by air and water pollution and deforestation as a byproduct. Since then, environmental health and ecosystem of Brazil have been facing tremendous threat owing to these pollution problems which may indirectly distress the EPI score of Brazil. Keeping these issues in mind, the present study investigates the relationship between FDI inflow and EPI score in Brazil. With the help of descriptive statistical tools as well as Pearson correlation test, this study finds the negative relationship between FDI inflow and EPI score in Brazil.

The Brazilian energy sector adopted a new regulation system in 2015 due to a system collapse threat. The system was changed to contractually incorporate firms’ economic-financial monitoring. This paper aims to assess the progress of this monitoring model toward achieving its goals. Thus, we proceed with a triangulation with three analyses. First, we analyse the literature to indicate if the economic-financial monitoring shows a hybrid form of adoption as suggested by the literature as the most suitable towards achieving regulatory goals. Second, we verify the perception of the economic-financial monitoring efficiency by the regulatory agency. Third, we evaluate the behaviour of some financial indicators before and after the new regulation. Our results show that, first, the economic-financial monitoring adopts a hybrid form which may drives better monitoring. Second, the perception of the regulator regarding efficiency of the financial monitoring model is favourable. Third, our results show that the sector leverage and profitability variances were significantly reduced after the implementation of financial monitoring which indicates less Asymmetric Information and consequently, better monitoring. In general, our results indicate some uncertainty reduction and more uniform behaviour of the entire sector after adopting an economic-financial monitoring system.

Keratoconus (KN), is an eye disorder, characterized by progressive thinning and protrusion of central cornea. A number of conditions such as such as allergy, asthma, eczema, and eye rubbing has been shown to be associated with the development of KN. However, there is a disagreement regarding some of risk factors and their strength so we conducted systematic review and meta-analysis to determine how strongly risk factors such as eye rubbing, and atopic triad associate with KN development and progression. We systematically searched the literature for related studies using specific keywords and key phrases. The studies were scrutinized based on inclusion and exclusion criteria. Finally, we extracted relevant qualitative and quantitate information from studies. For meta-analysis we used odds ratio (OR) and their 95% CI were used to draw forest plots. 35 studies were selected in final meta-analysis. Our meta-analysis yielded the combined effect of risk factors with OR of 2.20 and a 95% CI of 1.84–2.64. Furthermore, we found that eye rubbing-related studies had effect size of OR 2.09 with a 95% CI of 1.76–2.49 and a p value of 0.00001. For atopic triad (allergic rhinits, asthma and eczema) related studies, the meta-analysis yielded overall effect size of OR 2.34 with 95% CI of 2.06-2.66. Eye rubbing and atopic triad (allergic rhinitis, eczema, and asthma) are important risk factors for KC development with statistically strong association.

Background: Antenatal care is the care of a woman during pregnancy. The primary aim of antenatal care is to achieve at the end of pregnancy a healthy mother and a healthy baby. To improve maternal health, barriers which limit access to quality maternal health services must be identified and addressed at all levels of health system. Objectives were to determine demographic and obstetric factors affecting utilization of ANC service and prevalence of anaemia among pregnant women.Methods: This is cross-sectional descriptive study carried out in tertiary care hospital, using structured questionnaire, interviews were conducted with married pregnant women age between 18-45 years, who visited ANC clinic. Total 170 pregnant women visited hospital during a period was included in study. Data was analysed using MS excel and Epi info. Chi –square test was applied.Results: Maximum number of study subjects (42.9%) from age 23-27 years. 66.5% were Hindu, 56.5% study subjects from joint family. 14.7% were illiterate. 45.3% were primigravida, 54.7% were multigravida. 71.1% study subjects were from third trimester of pregnancy. 94.7% were taken at least one dose of Tetanus Toxoids. Iron folic acid tablets were taken by 87.6%. Prevalence of anaemia was 55.8%.Conclusions: Majority of pregnant women came for antenatal check-up, but regularity was not seen in most of cases. The presence study has brought out no significant socio-cultural barrier like women’s literacy, socio economic class and parity of women affecting the utilization of services.
