From Print to Digital, from Document to Data: Digitalisation at the Publications Office of the European Union
Authors: Schafer Valérie
Published: December 2020

Since the 1970s, the Publications Office of the European Union, the official publisher of all the institutions and bodies of the EU, has had to adapt to a fast-changing situation as the number of EU Member States has grown and the number and nature of publications has evolved (including publishing public tenders of EU institutions and Member States in 1978 through a supplement to the Official Journal of the European Union and handling CELEX, an interinstitutional and multilingual automated documentation system for community law, in 1992). These changes occurred over several ages of computing. The computerisation of the Publications Office was primarily a response to the need for rationalisation and productivity, but the aim was also to gradually adapt to new types of document publication and consultation. These different stages of digitalisation required the constant transfer of information to a multitude of media. Supports, such as punched cards, optical discs and CD-ROMs, had varying life expectancies and are all evidence of attempts to digitise information before the Web.

This evolution not only illustrates the need to constantly harmonise a large amount of information, it also highlights some continuities. It affects the management of information systems but also meets regularly updated standardisation, interoperability and sustainability needs within a complex ecosystem.
Pre-selected class-level testing of longitudinal biomarkers reduces required multiple testing corrections to yield novel insights in longitudinal small sample human studies
Authors: Foulkes Andrea S. , Azzoni Livio , Montaner Luis J.
Published: December 2020

Objectives

Exploratory studies that aim to evaluate novel therapeutic strategies in human cohorts often involve the collection of hundreds of variables measured over time on a small sample of individuals. Stringent error control for testing hypotheses in this setting renders it difficult to identify statistically signification associations. The objective of this study is to demonstrate how leveraging prior information about the biological relationships among variables can increase power for novel discovery.

Methods

We apply the class level association score statistic for longitudinal data (CLASS-LD) as an analysis strategy that complements single variable tests. An example is presented that aims to evaluate the relationships among 14 T-cell and monocyte activation variables measured with CD4 T-cell count over three time points after antiretroviral therapy (n=62).

Results

CLASS-LD using three classes with emphasis on T-cell activation with either classical vs. intermediate/inflammatory monocyte subsets detected associations in two of three classes, while single variable testing detected only one out of the 14 variables considered.

Conclusions

Application of a class-level testing strategy provides an alternative to single immune variables by defining hypotheses based on a collection of variables that share a known underlying biological relationship. Broader use of class-level analysis is expected to increase the available information that can be derived from limited sample clinical studies.
Finite element model of laminate construction element with multi-phase microstructure
Authors: Marszałek Jerzy , Stadnicki Jacek , Danielczyk Piotr
Published: December 2020

The article describes a method of creating a mesoscale finite element model of a fabric reinforced laminate that replicates the smallest repetitive fragment of its microstructure – RUC (Repetitive Unit Cell). The model takes into account the influence of the number and orientation of layers, the weave of the reinforcement fabric as well as manufacturing technology on the strength and stiffness of the laminate. The constants of the finite elements forming RUC (equivalent cross-sectional parameters, limit values of forces ensuring layer integrity) are determined experimentally by performing uncomplicated tests of specimens of a particular laminate. A special preprocessor was developed to generate the finite element model of the construction element from laminate, which automatically creates the so-called batch file defining the model. The usefulness of the preprocessor was checked by simulating a three-point bending test of a laminate door beam of a passenger car. The obtained calculation results were verified experimentally.

Authors: Zhao Hongkai , Zhang Kehan , Rui Shoupeng , Zhao Peipei
Published: December 2020

In the present contribution, an environmental-friendly and cost-effective adsorbent was reported for soil treatment and desertification control. A novel foam gel material was synthesized here by the physical foaming in the absence of catalyst. By adopting modified microcrystalline cellulose and chitosan as raw materials and sodium dodecyl sulfonate (SDS) as foaming agent, a microcrystalline cellulose/chitosan blend foam gel was synthesized. It is expected to replace polymers derived from petroleum for agricultural applications. In addition, a systematical study was conducted on the adsorbability, water holding capacity and re-expansion performance of foam gel in deionized water and brine under different SDS concentrations (2%–5%) as well as adsorption time. To be specific, the adsorption capacity of foam gel was up to 105g/g in distilled water and 54g/g in brine, indicating a high water absorption performance. As revealed from the results of Fourier transform infrared spectroscopy (FTIR) analysis, both the amino group of chitosan and the aldehyde group modified by cellulose were involved. According to the results of Scanning electron microscope (SEM) analysis, the foam gel was found to exhibit an interconnected pore network with uniform pore space. As suggested by Bet analysis, the macroporous structure was formed in the sample, and the pore size ranged from 0 to 170nm. The mentioned findings demonstrated that the foam gel material of this study refers to a potential environmental absorbent to improve soil and desert environments. It can act as a powerful alternative to conventional petroleum derived polymers.
Openness-inflation Nexus in alternative monetary regimes
Authors: Lin Pei-Chien , Huang Ho-Chuan , Liu Xiaojian
Published: December 2020

By applying an endogenous switching regression model to a sample of 64 countries, this article explores whether the effect of trade openness on inflation is influenced by the adoption of inflation targeting (IT). The outcome indicates that, while there exists a significant and negative impact of trade openness on inflation in the non-IT countries with flexible exchange rate system, the effect is negligible in the IT economies. In addition, the above differential inflation effect of trade openness across IT and non-IT regimes is only present in the developing subsample with flexible exchange rate system, but not the developed counterpart. Moreover, apart from trade openness, financial openness reinforces inflation in those developing countries not adopting IT, whereas no such significant effect is found in developing countries adopting IT. Instead of inflation, further results show that trade openness lowers inflation volatility both in developing and developed countries not adopting IT, yet the impact is smaller in developed country group. However, no such statistically significant link is found in developing and developed countries that adopt IT.
Maximum nullity and zero forcing of circulant graphs
Authors: Duong Linh , Kroschel Brenda K. , Riddell Michael , Vander Meulen Kevin N. , Van Tuyl Adam
Published: December 2020

The zero forcing number of a graph has been applied to communication complexity, electrical power grid monitoring, and some inverse eigenvalue problems. It is well-known that the zero forcing number of a graph provides a lower bound on the minimum rank of a graph. In this paper we bound and characterize the zero forcing number of various circulant graphs, including families of bipartite circulants, as well as all cubic circulants. We extend the definition of the Möbius ladder to a type of torus product to obtain bounds on the minimum rank and the maximum nullity on these products. We obtain equality for torus products by employing orthogonal Hankel matrices. In fact, in every circulant graph for which we have determined these numbers, the maximum nullity equals the zero forcing number. It is an open question whether this holds for all circulant graphs.

Primera parte. Del conflicto armado a la paz ambiental. Capítulo 2. De la evaluación económica a la evaluación sociopolítica de las políticas públicas ambientales y agrarias en Colombia
Authors: Omar Vivas-Cortés , Adriana Otálora-Buitrago
Published: December 2020

Uno de los debates contemporáneos sobre medio ambiente y sostenibilidad tiene que ver con las evaluaciones de las políticas ambientales y el reconocimiento de la naturaleza política que ellas dan al proceso de implementación; diversas fallas de implementación que son originadas por la acción política de los actores que participan en la esfera de la política y en la implementación de las políticas, inciden de manera negativa en las mismas. Desconocer esta naturaleza conduce a una incomprensión de las fuerzas políticas, es decir, del universo de actores que agencian sus intereses en el espacio de la política y cuya eficacia marca los resultados de los programas públicos, además, es la acción política de tales actores lo que define el statu quo de la distribución de los valores entre quienes habitan el ámbito político intervenido. En este universo, lo determinante son las reglas del juego político de los actores que participan en la implementación, por su parte, lo referencial de la formulación de la política es un conjunto de orientaciones normativas, imágenes, valores y algoritmos que sirven de esfera dialéctica de la comunicación y la argumentación para los participantes y sus relacionamientos.

Published: December 2020

Introduction: Insulin-like growth factors (IGF´s) play a crucial role in controlling cancer cell proliferation, differentiation and apoptosis. Exercise has been postulated as an effective intervention in improving cancer-related outcomes and survival, although its effects on IGF´s are not well understood. This meta-analysis aimed to determine the effects of exercise in modulating IGF´s system in breast cancer survivors. Methods: Databases of PuMed, EMBASE, Cochrane Central Register of Controlled Trials, EMBASE, ClinicalTrials.gov, SPORTdiscus, LILACS and Scopus were systematically searched up to November 2014. Effect estimates were calculated through a random-effects model of meta- analysis according to the DerSimonian and Laird method. Heterogeneity was evaluated with the I 2 test. Risk of bias and methodological quality were evaluated using the PEDro score.
Mathematical modeling of probe measurements in a supersonic flow of a four-component collisionless plasma

The aim of this work is the development of a procedure for extracting the plasma electron density and temperature and ion composition from the current-voltage characteristic (C –V characteristic) of an isolated probe system of cylindrical electrodes. The plasma is four-component and consists of electrons, ions of two species with significantly different masses, and neutrals. The measuring probe and the reference electrode of the probe system may be made up of several cylinders. The electrodes of the probe system are placed transversely to a supersonic flow of a low-temperature collisionless plasma with a specified mass velocity. Using the familiar theoretical and experimental relationships for the ion and electron currents to a cylinder, a mathematical model of current collection is constructed for an isolated probe system at an arbitrary ratio of the electrode surface areas. The model includes the calculation of the equilibrium potential of the reference electrode as a function of the probe bias voltage. A procedure is developed for the identification of local plasma parameters using a priori information on the plasma properties and the experimental conditions. The effect of the electron density and temperature and the ion composition on the probe current of the isolated probe system at different ratios of the current-collecting electrode surface areas is studied. The ranges of the probe bias potentials and the values of the electrode surface area ratio that maximize and minimize the effect of the sought-for parameters on the probe current are determined. The quantitative restrictions on the bias potentials and the surface area ratio obtained in this study are used in the probe measurement procedure and in the objective function for comparing the theoretical approximation of the probe current with the measured I– characteristics. A numerical simulation of probe measurements under the ionospheric conditions was conducted to verify the efficiency of the procedure for extracting the local parameters of a four-component plasma from the electron branch of the I –V characteristic of an isolated probe system. The results obtained may be used in ionospheric plasma diagnostics onboard nanosatellites.
Approximate solution of hypersingular integral equations on the number axis
Authors: Boykov Ilya V. , Aykashev Pavel V. , Boykova Alla I.
Published: December 2020

In the paper we investigate approximate methods for solving linear and nonlinear hypersingular integral equations defined on the number axis. We study equations with the second-order singularities because such equations are widely used in problems of natural science and technology. Three computational schemes are proposed for solving linear hypersingular integral equations. The first one is based on the mechanical quadrature method. We used rational functions as the basic ones. The second computational scheme is based on the spline-collocation method with the first-order splines. The third computational scheme uses the zero-order splines. Continuous method for solving operator equations has been used for justification and implementation of the proposed schemes. The application of the method allows to weaken the requirements imposed on the original equation. It is sufficient to require solvability for a given right-hand side. The continuous operator method is based on Lyapunov's stability for solutions of systems of ordinary differential equations. Thus it is stable for perturbations of coefficients and of right-hand sides. Approximate methods for solving nonlinear hypersingular integral equations are presented by the example of the Peierls - Naborro equation of dislocation theory. By analogy with linear hypersingular integral equations, three computational schemes have been constructed to solve this equation. The justification and implementation are based on continuous method for solving operator equations. The effectiveness of the proposed schemes is shown on solving the Peierls - Naborro equation.

Authors: Poltavtseva Maria A.
Published: December 2020

Monitoring of industrial cyber-physical systems (CPS) is an ongoing process necessary to ensure their security. The effectiveness of information security monitoring depends on the quality and speed of collection, processing, and analyzing of heterogeneous CPS data. Today, there are many methods of analysis for solving security problems of distributed industrial CPS. These methods have different requirements for the input data characteristics, but there are common features in them due to the subject area. The work is devoted to preliminary data processing for the security monitoring of industrial CPS in modern conditions. The general architecture defines the use of aggregation and normalization methods for data preprocessing. The work includes the issue from the requirements for the preprocessing system, the specifics of the subject area, to the general architecture and specific methods of multidimensional data aggregation.

Authors: Berezin Andrey Aleksandrovich , Novikov Roman Sergeevich , Novopashin Maxim Aleksandrovich , Pozin Boris Aronovich , Shmid Alexander Viktorovich
Published: December 2020

Method for conducting a non-invasive screening of the population for carbohydrate metabolism disorders (CMD) has been developed and described. The novelty of the method is that there are no medical standards in the field of endocrinology for the non-invasive type of screening, so the method was based on the results of a clinical study of electrocardiographic abnormalities in patients with CMD, where the method of non-invasive determination of CMD by first-lead ECG was used. During the development of the method, an additional analysis of the ECG sample obtained during the study was performed. As a result of the analysis, it was concluded that the effectiveness of the method (sensitivity and specificity) vary slightly depending on the time of taking an ECG during the day. This means that the patient can come to the screening using the new method of non-invasive detection of CMD not only in the morning and not necessarily on an empty stomach, in contrast to the invasive methods (fasting plasma glucose test and oral glucose tolerance test). To make a decision «there is a suspicion of CMD /there is no suspicion of CMD», the patient only needs to take up to 2 ECGs.

Published: December 2020

The article analyzes the development of the system of departmental management of closed cities in Russia in the period from the 1940s to the 2000s. For convenience, the temporary frames of the study are divided into three periods: the first dated 1945-1954, the second is 1954-1991, and the third period, which dates back to 1991, continues at the present stage and is relevant to the study to this day. At each of these periods, the main features of the system of departmental management of closed cities at the Federal, regional and municipal levels were highlighted. The analysis of the departmental management system is based on the normative legal acts issued by the Presidium of the Supreme Soviet of the RSFSR in the Soviet period, and the government of the Russian Federation in the post-Soviet period. The results of the work revealed a specific way to establish a departmental structure for managing closed cities, with a number of features characteristic of secret territories.
POLITICAL AND ADMINISTRATIVE ASPECT OF ADMINISTRATIVE-TERRITORIAL REFORMS OF THE 1930TH ‒ THE 1950TH IN MODERN RUSSIAN HISTORIOGRAPHY

Published: December 2020

The article considers historiographic assessments of the administrative-territorial transformations of the Stalinist period of Soviet history through the prism of relations "Center - Regions." For the supreme government in the period under study, the obvious dilemma was the choice between the economic efficiency of the spatial development of enlarged and self-sufficient regions, on the one hand, and the increase in the political manageability of the Center for regional development, on the other hand. The policy of disengaging the regions and giving the former dis-trict centers the status of regional capitals was connected with the need of the Cen-ter to monitor the processes of industrialization and collectivization, bring man-agement closer to production, as well as weaken the influence of regional leaders to strengthen the regime of personal power of I.V. Stalin. Subsequently, the political struggle for power in the 1950s. contributed to a gradual and irreversible review of the relationship between the central and regional authorities: for political reasons, the Center abandoned the administrative-territorial transformations of the regions.

The need for a full-fledged performance measurement system in field of quality of the public administration in Russia remains on the agenda in the light of strategic initiatives for the development of the country. The existing approaches to quality assessment, based on ranking and rating, perform a control function, but do not give government bodies at various levels, local governments, public sector organizations the necessary tools to improve performance. In this regard, in recent years, Russia has been in search of models, methods of increasing efficiency and improving the quality of activities of state and municipal authorities and public sec-tor organizations. The article is devoted to one of the modern models of quality management in the field of public administration – the European model for improving the activities of public sector organizations through the self-assessment – the Common Assessment Framework (CAF model) and the possibilities of its application in Russia. The article was prepared as part of the research of the state assignment of the RANEPA.

There are many directions and methods of researching and assessing coastal changes and coastal erosion. This study presents the results of the shoreline changes in the area from Son Tra (Da Nang City) to Cua Dai (Hoi An City), Central Vietnam based on remote sensing data from 1965 to 2019. Three methods are used to include End Point Ratio (EPR), Linear Regression Rate (LRR), and Weighted Linear Regression (WLR). The results show that the EPR method is effective when calculating the rate of shoreline changes only at two different times. For more objective and reliable calculation, it is necessary to assess the shoreline changes over time. Meanwhile, the LRR method was shown to be superior because all shoreline data were taken into account during the construction of the regression line. However, when there is much shoreline data with different reliability, the WLR method proved more superior because of limited objective errors. The results show that from 1965 to 2019, the coast of the Son Tra - Cua Dai area had quite complicated fluctuations, of which the northern area (Son Tra) tended to accretion, the central area tends to be alternate between accretion and erosion, while the south area (Cua Dai) is strong to very strong erosion. The coast with sudden changes is the Cua Dai area with the shoreline change envelope (SCE) reaching 512m. The results also allow us to divide the coast of the Son Tra - Cua Dai area into 30 segments. They are clustered into 8 groups with different levels of erosion and accretion. This is an important basis for the setback zone establishment in the study area.

The need to reduce energy consumptions in buildings brings modern research to focus on the use of natural sources. In this context, the interest towards traditional architecture has been fueled, since one of the characteristics identifying it is the intuitive and intrinsic link between the building and the surrounding environment. For example, in Mediterranean traditional buildings the attention to the orientation, the limitation of openings, the use of shading systems, the great thermal inertia of the envelope, the exploitation of natural ventilation and the light colored external coatings are all technical answers to the overheating risks typical of hot climates. In this context, the Portuguese traditional habit to cover building façades in azulejos (square ceramic tiles painted in vivid colors) is undoubtfully an interesting topic. The paper describes optical and chromatic characteristics of four types of azulejos by means of spectral measurements. Obtained results have demonstrated that the chromatic composition of the tiles, despite dark colors are mixed with clear ones, is such to determine visual reflectance values higher than expected. This seems to suggest that, even if the chromatic composition in the past was mostly driven by decorative issues and visual intuitive judgments, the energetic needs were not completely neglected or at least that the traditionally preferred colors were such to obtain a positive effect in enhancing reflected component of daylight.
The Legal Regulation of the Relations in Oil and Gas Production: The Problem Statement
Authors: Kuleshova Anastasia
Published: December 2020

Introduction: the paper deals with certain issues of the legal regulation of the relations in oil and gas production. The reasons for the fragmentary and non-systematic legal regulation of the economic relations for the planning and working of mines by the special legislation are highlighted. The paper considers the system of norms regulating the control in the Russian Federation, which requires further development regarding the establishment of sanctions for the violations of environmental safety and negative impact on the environment. The purpose of research: to analyze the features of the legal regulation of public relations in the oil and gas sector, identify the theoretical positions and problems of the law enforcement, and form recommendations for improving the legislation in this area. The research used the following methods: the general method (dialectical materialism); the general scientific methods (logical (induction, deduction, analysis and synthesis), system and functional); private law methods (formal legal, comparative legal). Results: the issues of the legal regulation of the regime of oil and petroleum products are considered, and the theoretical concepts are presented. The problems of the law enforcement based on the dual interpretation of the norms of law in the oil sector and, as a result, their incorrect application are identified. The problem of the local regulation of the fuel and economic complex is raised and the recommendation is made to generalize or fill in the gaps in the regulations in the sphere of regulating public relations in the oil and gas industry. Conclusion: the author substantiates the need to fill in the gaps in the legislation starting from the bylaw regulation and to rely on the practical experience of the companies in the field of oil and gas production. It is argued that it is possible to fill in the gaps in the law at the first stage by means of issuing orders from the ministries and departments.

The goal of the paper is to present the theoretical foundations of a unique training program aimed at providing students with a complex of knowledge, skills and abilities needed to understand the specifics of color communication in old and very old age. The objectives of the paper include an analytical review of the sources that have defined the program content, the structure of the educational module, and its methodological basis. The selection of research sources was carried out through the RSCI, Google Scholar, Scopus, and Web of Science systems. In the process of work the methods of theoretical and comparative analysis, systematization and generalization of materials were used. The authors provide a detailed analysis of the sources, which represent the dynamics of age-related physiological changes in color vision and examine their impact on color communication of elderly people. Each of the theoretical models included into the review makes a special contribution to the development of the problem. The experiments with colored glasses of K. Ishihara et al. provide an opportunity to feel the impact of age-related decline in visual ability on everyday life and habits of an aging person. The research of D.T. Lindsay and A.M. Brown helps to understand how aging of the eye influences perception of individual shades. The method of M.F. Hassan's research group simulates how elderly people see different color combinations and complex images. An optical google of
T. Suzuki et al. enables young people to experience senile miosis in any environment in real time under different illuminance conditions. J.L. Hardy's et al. experiment explains why elderly people often do not realize that their color perception is changing. In the complex, all the studies presented in the review help students to better understand the specifics of color communication in old and very old age, and thus to form a sustainable complex of knowledge, skills and abilities necessary for improving the quality of color design projects, creating by young professionals for elderly people
A escravidão como mal de arquivo: apagamento e acontecimento na história do Brasil
Authors: Veríssimo Tânia Corghi
Published: December 2020

Resumo: O presente texto propõe discutir a complexidade do arquivo da escravidão no Brasil em suas dimensões de apagamento e acontecimento na história do país. Para tanto, tomará como eixo o cotejo entre duas produções discursivas postas no laço social brasileiro, sendo estas o Hino da República de 1890 e o samba enredo produzido pela escola carnavalesca carioca Estação Primeira de Mangueira no ano de 2019. Tomando como referencial teórico o mal de arquivo derridiano, pretende-se, ao longo do artigo, explorar as subversões apresentadas por esta concepção de arquivo inovadora e fortemente marcada pelas noções freudianas de memória e pulsão de morte, bem como sustentar que a desconstrução do conceito de arquivo metafísico incide no campo político de modo a produzir consequências importantes no mesmo.
Modelos y problemas en el estudio de la circulación de la teoría literaria: Pierre Bourdieu (1989), Pascale Casanova (1999) y el secuestro del barroco
Authors: Nácher Max Hidalgo
Published: December 2020

Resumen Este artículo repasa críticamente algunos de los modelos historiográficos universalistas más destacados en el estudio de la circulación de la literatura y de la teoría literaria. La conferencia “Les conditions sociales de la circulation internationale des idées” (1989), de Pierre Bourdieu coincide cronológicamente con la publicación de O sequestro do barroco na formação da literatura brasileira: o caso Gregório de Matos, en la cual Haroldo de Campos proponía una lectura crítica de la Formação da literatura brasileira (1959), de Antonio Candido. Desde esas coordenadas, es posible aislar en la literatura mundial -a través de la lectura de La République mondiale des Lettres (1999), de Pascale Casanova- otro “secuestro del Barroco” que hay que retrotraer hasta mucho más atrás y que se hace visible gracias a trabajos como el llevado a cabo por Leyla Perrone-Moisés y Emir Rodríguez Monegal en Lautréamont austral (1984). Esas obras no son aquí traídas en sí mismas, sino en tanto que siguen repitiéndose o interpelándonos en el presente, pues la ascendencia de modelos y prácticas monológicas se transmiten de las historias nacionales a las historias mundiales de la literatura, y sigue siendo actuante hoy en día.
Uma teoria do verso: amor e catástrofe
Authors: Magalhães Danielle
Published: December 2020

Resumo A partir de uma abordagem pelo desencaixe, pela disjunção, pela desarticulação, ou, ainda, pela suspensão, pela interrupção, por um ponto de crise, propõe-se articular princípios em comum que comparecem em teorias sobre o amor, sobre o tempo e sobre o verso. É possível associar a leitura do verso como um “lance”, desde Um Lance de Dados de Mallarmé, à leitura que Jacques Lacan faz do amor em Encore? Poderíamos ler o salto do verso como o anjo da história de Benjamin, que é impelido para frente, mas se volta para trás encarando fixamente a catástrofe? Ir ao verso é ir ao tempo em sua crise, em sua fratura, em sua disjunção, tal como pensaram Agamben, Benjamin, Derrida? Essas são as direções pelas quais este artigo propõe ler, no gesto disjuntivo do verso, erotismo e luto, amor e catástrofe.
A autoficção e o romance contemporâneo
Authors: Figueiredo Eurídice
Published: December 2020

Resumo Este artigo parte da ideia de que o mundo de hoje se caracteriza pela exposição da vida privada, o que acarreta mudanças nas figurações do romance. Haveria, assim, um entrecruzamento entre a autoficção e o romance contemporâneo, que se apropria de elementos das escritas de si a fim de dar a impressão de que é baseado em fatos reais. Após estabelecer uma arqueologia da autoficção na França, onde o termo surgiu, o artigo apresenta alguns problemas éticos que transparecem quando escritores decidem desnudar-se em público, levando consigo familiares e amigos.
