Aim. To estimate the efficacy of catheter ablation in patients with type 2 diabetes mellitus (T2D) present with atrial fibrillation and sick sinus syndrome (SSS) undergoing permanent pacemaker implantation.

Methods. 56 patients (34 females) with persistent AF and SSS were enrolled in the study. The mean age of patients was 67.7±10.7 years. Dual chamber cardiac pacemaker with remote monitoring function were implanted in all patients. All the patients were assigned to two groups: Group 1 comprised 31 patients aged 67.3±9.6 years, and Group 2 comprised 25 patients aged 72.6±9.9 years, including 22 (39.2%) diabetic patients. 2-3 days after pacemaker implantation, group 1 patients underwent intracardiac electrophysiology study and RFA of the pulmonary vein ostia, mitral isthmus and the left atrial posterior wall. Group 2 patients received antiarrhythmic drug therapy.

 Results. 3 patients (9%) in Group 1 had recurrent AF within the 6-month follow-up. The efficacy of the RFA for AF was 55% (n = 17) 1 year after the indexed hospitalization. 8 patients had short paroxysmal attacks which gradually lessened and stopped after. 5 patients (21%) in Group 2 did not have any AF paroxysms within the 1-year follow-up (Х2 = 5.52, р = 0.02). All these patients received amiodarone as antiarrhythmic drug therapy, whereas the others had paroxysmal attacks. Frequent attacks in 10 patients (40%) led to a change in antiarrhythmic drug use. Hospital readmission rates for AF were 16% and 52%, respectively (Х2 = 4.15, р = 0.04). The impact of atrial and ventricular stimulation on the development of recurrent AF was statistically insignificant (atrial stimulation – X2 = 0.01, cc = 1, p = 0.90; ventricular stimulation – X2 = 0.15, cc = 1, p = 0.69). None paroxysmal attacks were recorded in 10 diabetic patients (45%) after the RFA within the 1-year follow-up.

Conclusion. Catheter ablation for persistent AF and SSS treated with permanent pacemakers is highly effective and safe method. In addition, it is superior to pharmacological approach. The presence of T2D likely did not significantly affect the efficacy of RFA for persistent form of AF.

Authors: Kochergin N. A. , Kochergina A. M. , Ganjukov V. I. , Barbarash O. L.
Published: September 2018

Background. Acute coronary syndrome remains the leading cause of death worldwide. The rupture of vulnerable atherosclerotic plaque in the coronary artery is a common pathogenetic mechanism contributing to the onset of acute coronary syndrome. Therefore, one of the main goals of the practical cardiology is to ensure the development of sensitive early diagnostic methods and set preventive and treatment strategies for acute coronary event. Aim To evaluate the incidence of vulnerable plaques in the non-target coronary arteries in patients with stable coronary artery disease.

Methods. 58 patients with stable coronary artery disease were included in a prospective observational cohort study. After the target vessel had been stented, virtual histology intravascular ultrasound (VH-IVUS) of the proximal and middle segments (6–8 cm) of one non-target artery (i.e. without any significant stenotic lesions on coronary angiography) was performed.

Results. The mean age of patients was 60.4±6.6 years. In addition to the targeted hemodynamically significant lesions subjected to stenting, 56 patients had 58 lesions (96.5%) in the non-target coronary arteries. Of them, 5 lesions (8.6%) were with >70% luminal stenosis (including >70% luminal stenosis + lumen area <4 mm2 in 4 cases), 10 lesions (17.2%) – with minimum lumine area <4 mm2 and without any other signs of vulnerable plaque, 12 lesions (20.7%) – with a large necrotic core and a thin cap (including thin-cap fibroatheroma + >70% luminal stenosis in 2 patients; thin-cap fibroatheroma + lumen area <4 mm2 – 2 cases, thin-cap fibroatheroma + >70% luminal stenosis + lumen area <4 mm2 – 2 cases).

Conclusion. In vivo evaluation of the plaques in the non-target vessels ensures the detection of vulnerable plaques in stable patients. The long-term follow-up of the study group allows assessing the risk of developing adverse cardiovascular events in those patients who have vulnerable coronary plaques.
TRANSRADIAL AND TRANSFEMORAL ACCESS FOR CAROTID ARTERY STENTING WITH AN EMPHASIS ON THE DETECTION OF MICROEMBOLIZATION WITH DIFFUSION WEIGHTED MAGNETIC RESONANCE IMAGING (TACTILE TRIAL).
Authors: Malaev D. U. , Kretov E. I. , Baystrukov V. I. , Naidenov R. A. , Prokhorikhin A. A. , Boykov A. A.
Published: September 2018

Aim. To compare transradial (TR) and transfemoral (TF) approach for carotid artery stenting (CAS) with an emphasis on the detection of micro-embolization with diffusion-weighted magnetic resonance imaging (DW-MRI).

Methods. 96 patients were included in the study in the period from January 2015 to October 2017 with further randomized 1 : 1 to the TR and TF groups. The inclusion criteria were the following: symptomatic stenosis ICA >70%; or asymptomatic stenosis ICA >80%. The positive history of stroke, myocardial infarction or open heart surgery <1 month were the exclusion criteria for the study. The primary endpoint was the incidence of new cerebral ischemic lesions as assessed by DW-MRI. All CAS procedures were performed by two experienced operators according to the approved protocol.

Results. Procedural success with TR approach was 46 (96%) versus 48 (100%) with TF approach (p = 0.495). Crossover rate was 4% in the TR group. The rate of primary endpoint in the TR and TF groups was 50 and 52%, respectively. The absolute risk difference was -2% (95% CI [-0.21, 0.17], p (non-inferiority) = 0.03). An «on-treatment» analysis revealed a tendency towards a reduced microembolic foci when intervening on the right ICA via TR approach compared to TF (44% vs. 68%, p = 0.478), and a reverse trend when intervening on the left ICA via TR compared to TF approach (57% versus 36%, respectively, p = 0.437).

Conclusion. Carotid stenting via transradial approach is noninferior for cerebral embolism to transfemoral approach. The rates of MACCE and vascular complications were similar in both groups. There was no significant difference in the procedural success rate in the transfemoral and transradial groups. The fluoroscopy time during transradial carotid stenting was higher in comparison with transfemoral carotid stenting, though the procedure duration was similar in both groups.
Language And Humour In Charles Dickens’s Little Dorrit
Authors: Diesel Sophia Celina
Published: September 2018

The language of Charles Dickens evolved throughout his career, characteristically becoming more sophisticated in his later novelssuch as Little Dorrit. Considered by the critic and the public more serious and calculatedly darker than previous successes those novelsare as well full of humour and irony. The difference is that the humour also became more sophisticated and poignant. This essay discusses – supported by criticism such as The Dark Effigy: a study of Dickens’s Imagination by professor John Carrey from Oxford University – the violence implied by the author in the humour of his mature language and how this humour is produced along with misunderstandings and blocked dialogue of characters in Little Dorrit. The problematic communication produces an atrophied flow of energy which matches the prison theme of the novel enabling those characters to be free and happy, and emphasising the causes for this problems in their also atrophied Victorian society.

Arabismos portugueses no contexto multilinguístico da Península Ibérica Medieval
Authors: Maranhão Samantha de Moura
Published: September 2018

Este estudo tem por objeto a aquisição de arabismos pelos falares regionais, e particularmente pela língua portuguesa, no contato multilinguístico verificado na Península Ibérica, durante a Idade Média. Apresenta a história externa da língua portuguesa, com a definição e a caracterização dos espaços que a geopolítica então delimitou e as relações estabelecidas entre diferentes grupos étnico-religiosos, cristão, muçulmano e judeu, que os compartilharam. O problema da pesquisa é: “O que informa a literatura especializada acerca do contato de línguas na Ibéria Medieval?” A hipótese testada é a de que a diglossia árabe-romance está fartamente documentada na literatura especializada no tema dos arabismos ibéricos medievais. Fundamentam este estudo obras sobre arabismos (VARGENS, 2007; CORRIENTE, 1996), história da língua portuguesa (TEYSSIER, 2001; VASCONCELOS, 1956; SILVA NETO, 1988) e história (CONSTABLE, 1997; THORAVAL, 1996).
Narrações-munições: sinais da memória violenta nos contos testemunhais de Reinaldo Arenas
Authors: Nodal Antonio Martínez , Pereira de Souza Carla Dameane
Published: September 2018

Neste artigo analisamos a presença autoral de Reinaldo Arenas em suas narrativas breves exponencialmente autobiográficas, procurando, nessas vivências, singulares batalhas e desacordos com o Estado cubano revolucionário e o espaço afetivo coercitivo de sua escrita. O confronto das interpretações e as leituras da realidade do escritor dissidente com a história oficial podem-nos ajudar a identificar descrições ocultas na narrativa dos textos breves memoriais de Reinaldo Arenas e, consequentemente, a revelar alguns importantes conteúdos histórico-políticos e autoficcionais inseridos nos citados relatos. Desta maneira, os contos funcionam como narrações-munições, isto é, gestos literários que se revelam como ações simbólicas de resistência e de denúncia do sistema totalitário fidelista e de seu universo filial. Explicita-se, ademais, o componente testemunhal de suas fortes narrativas observado nas características de alguns relatos pertencentes à obra Termina el desfile (1981), que contém as variadas passagens histórico-críticas assinaladas na vida de Arenas, potencializadas pela violência familiar e a pulsão sexual latente do escritor cubano.
Da literatura como resistência eloquente: a tradução de Prometeu acorrentado sob a ditadura de Oliveira Salazar
Authors: Quadrio Miguel-Pedro
Published: September 2018

Este artigo incide sobre a tradução em língua portuguesa de Prometeu acorrentando que Eduardo Scarlatti publicou em Lisboa, em 1942. Atribui-se particular relevância a este texto por se considerar que, através dele, Scarlatti não pretendeu apenas apresentar mais uma versão de um texto canónico. Pela análise dos paratextos, das escolhas tradutológicas e remetendo-se para a reflexão crítica e teórica que anteriormente desenvolvera-se, verifica-se que a opção de Scarlatti correspondeu ao desejo de dotar a cultura portuguesa de um texto literariamente qualificado, pensado não só como ato de resistência à opressão salazarista, mas também como manifesto estético que impulsionasse a renovação do anémico sistema teatral. Assim, defende-se a condição de intelectual engajado de Scarlatti (BOURDIEU, 1991), sublinhando-se a constituição de uma linhagem de resistência que determinará mudanças culturais profundas em Portugal.
L’écriture et les signes inclusif·ve·s, avec ou sans ? Activité pédagogique de Français sur Objectifs Spécifiques
Authors: Sarzi Amade José
Published: September 2018

La question de l’emploi de l’écriture inclusive a occupé très récemment l’actualité en France. D’abord débat de société, elle a vite enflé et s’est transformée en polémique, opposant progressistes, féministes contre certains « puristes » ou conservateurs. En question, les inégalités entre sexes présentes aussi dans la langue française dont les règles d’orthographe en vigueur privilégieraient, de façon arbitraire, le masculin au féminin. Afin de remédier à la prétendue injustice, un système orthographique a priori plus paritaire a été conçu et presse désormais pour s’imposer dans les pratiques du français de tous les jours. Face au cloisonnement du débat, nous avons saisi l’occasion pour en faire un matériau servant à la didactique des langues étrangères et plus précisément, au FOS (Français sur Objectifs Spécifiques). Les questionnements techniques, sociolinguistiques autour de l’écriture inclusive et de son emploi nous ont permis d’imaginer un scénario possible de formation autour de ce thème, en le rendant sensible aux étudiants allophones d’une université.

Silêncio (o metro como elemento construtivo do vazio na poesia de Orides Fontela)
Authors: Belúzio Rafael Fava
Published: September 2018

Resumo: O artigo propõe uma análise dos cinco livros de poesia lírica publicados por Orides Fontela, Transposição (1969), Helianto (1973), Alba (1983), Rosácea (1986) e Teia (1996), a partir da metrificação do volume Poesia reunida [1969-1996]. O objetivo é compreender alguns modos de o metro participar da elaboração de uma estética silenciosa. Desse modo, os resultados apresentam recursos estéticos empregados pela autora, tais como a predominância de versos curtos; os versos quebrados; a logodaedalia; as estrofes com metro em queda; o espaço em branco enquanto metro vazio. Assim, o texto conclui que a métrica de Orides Fontela caminha para uma dessonorização, expressando a noção ampla de vazio, um dos pontos fundamentais da lírica oridiana.Palavras-chave: ritmo; poesia lírica; século XX.Abstract: This paper proposes an analysis of the following five books of lyric poetry published by Orides Fontela: Transposição (1969), Helianto (1973), Alba (1983), Rosácea (1986) and Teia (1996), by means of the Poesia reunida [1969-1996] metrification. The article aims to understand some ways in which the metric participates in the elaboration of silent aesthetics. In this regard, the results shed light on the aesthetic resources employed by the author, such as the predominance of short verses; the broken verses; the logodaedalia; the stanzas with falling metric; and the blank space as empty metric. Finally, the text concludes that Orides Fontela’s metric leads towards a sound loss, expressing the broad notion of emptiness that constitutes one of the fundamental points of the author’s lyric poetry.Keywords: rhythm; lyric poetry; twentieth century.
Fuzzy model for support investment decisions under risk
Authors:   Ufa State Aviation Technical University, К. Marks st. 12, Ufa, Russia, 450000, Orlova Ekaterina
Published: September 2018

One of the most important problem related to understanding the investor's behavior is to study the ways he selects, analyzes and interprets the available information and then uses it to make investment decisions. It is necessary to find out how an investor forms a certain opinion and comes to his own behavior strategy. The investor's behavioral model is variable since the financial market is volatile. The behavior of the investor is determined by a combination of rational (objective) and irrational (subjective) factors. To describe the influence of a combination of factors on the investor's behavior, a model describing this influence is needed. A formal description of interaction is complicated since a number of factors are of a qualitative nature, and the factors are also interrelated. The paper identifies the main causes and factors of irrationality in investor behavior which is the basis for its analyze and control. The fuzzy model, which allows to link a lot of behavioral factors with the utility (efficiency) of the solution is developed. Simulation results can be used for the investor’s utility functions designing that is required to decisions making justification.

To increase the effectiveness of detecting fraudulent bank transactions, the structure of the system is proposed to analyze data of user environment in order to identify potential fraudulent activities. The system for collecting and analyzing information about the user environment allows to accumulate data about the user environment, to mark precedents in manual and automatic modes and build a database of images for classifiers training. It is necessary to implement data collection, storage and access interface for the application of data mining tools. Operation of significant amount of accumulated data requires the use of special tools (frameworks and hardware platforms) for processing large data. In this paper the analysis of the existing software and hardware tools for distributed processing of indefinitely structured data of bank transactions (frameworks: Hadoop, Apache Spark) is presented. The structure and recommendations for the deployment of a hardware and software stand for testing algorithms for detecting financial fraud on the basis of data mining analysis as part of a distributed data processing system for bank transactions based on the selected framework are developed.

Сardiovascular diseases are one of the leading causes of death worldwide. People suffering from or at high risk of such diseases need constant supervision, early diagnosis and timely assistance. It is shown that the achievement of high accuracy performance in real-time arrhythmias recognition is associated with significant hardware costs. Detection accuracy of arrhythmias recognition does not exceed 80%. An approach, which is offered to solve the problem of high-precision arrhythmia diagnosis on the basis of electrocardiosignal is based on the data mining methods. Application of such methods is necessary for processing large amounts of data with complex structure of the features. Determination of the arrhythmia type with the use of fuzzy inference tools needs to specify the technique of the original data preprocessing. Feature selection, formalization and coding is considered in this paper. The issue of the knowledge base construction – coding, generation and selection of the features (database) as well as the construction of the rules base ¬ as the part of the neuro-fuzzy diagnostic system is also considered. The research goal is to improve the intelligent systems of arrhythmia diagnostics on the basis of neural network classifiers by developing a solution explanation subsystem based on neuro-fuzzy models.

The purpose of developing data warehouse architecture is improving the storage subsystem as part of an intelligent oil well control system. To achieve this goal, it is necessary to develop the structure and information model of the storage subsystem. It is proposed to expand the exploration and exploitation data model of the Epicentre oil fields by adding new entities and a hierarchy of links. Highly effective architectural templates, taking into account the specifics of the research object and the accumulated experience of industry experts, are used.

In this paper, we propose an approach to semantic differences detection in texts presented in the form of frequency dictionaries. The original text data has been obtained by collecting records on various online communities. We have implemented a specialized software module that allows us to analyze and download both posts and comments from the social network VK’s open communities. To build our frequency dictionary, we have developed in algorithm that takes into account the peculiarities of the data collected from social networks. In the article, we propose an approach based on the use of methods reducing the dimension offeature spaces to identify keywords based on the analysis of their frequency of usage. The algorithm we present uses the principal component analysis technique. As a result, we have shown that by using the coefficients of the obtained linear transformation, it is possible to estimate the importance of words. With the help of these estimates, we were able to identify not only key words, but also semantic differences in social networks communities. The proposed approach can also be used to form metrics and calculate the social distance between Internet communities.

The paper suggests a new approach to the selection of correlated concepts for the ontology. It is based on the principal component analysis, but, unlike the standard approach, not Pearson correlation coefficients, but other correlation measures are used. This is due to the fact that the selection of concepts is based on data on the semantic association between concepts and cases, which are represented in the form of weight coefficients that take discrete values and a significant number of zero values. For such cases, the most appropriate is the polychoric correlation coefficient. It allows one to detect a monotonous dependence on the contingency table. However, for a certain table structure, the coefficient erroneously indicates a close relationship. This problem has been analysed in detail, and it has been suggested to use the correlation ratio in problem cases. Using the example of the problem of selecting concepts for the ontology in the IT consulting practice, the advantages of the proposed approach are shown. The first oneis the increasein the percentage of variance of concepts explained by the principal components. The second one is that more concepts are selected based on unsupervised feature selection using weighted principal components.

The paper deals with the problem of data processing in adaptive detection of inspiration / expiration by machines for treating sleep apnea using statistical decision theory and based on preliminary analysis of human respiration. The authors establish a law of noise distribution and develop an inspiration and expiration detection algorithm which envisages calculation of the likelihood ratio, which is compared with the threshold values, at each step. As a result, a conclusion is drawn, and a decision is taken on the need to initiate the treatment of sleep apnea with the machine. The use of this algorithm reduces the detection time by 2-3 times, making it possible to carry out preliminary adjustment of parameters for each patient. The problem of definition of person s respiratory system condition with the use of the methods based on a task of the dosed values of resistance/pressure of switching in a respiratory contour with the subsequent creation of diagnostic matrixes state, in which every line characterizes parameters value at a certain loading for the throttle and relay modes of complexes correcting influence is solved.

The system of centrifugal compressor GTU has several 2FSI subsystems: impeller, labyrinth seals (LS), dummies, etc. The article analyzes dependence of one subsystem - the labyrinth seal - on its diameter. The effect of this parameter on the wave processes occurring in labyrinth seals during vibrations of the rotor is studied. A solution is obtained for a nonstationary aeroelastic three-dimensional gas flow problem in deformable LS. The amplitude-frequency characteristics of the gas dynamic and vibration parameters of the LS CC of GTU are obtained. Time dependences of the gas-dynamical force and the work of gasdynamic forces in the LS zone at different rotor diameters are obtained.

El artículo argumenta al respecto de cuáles son los siete aprendizajes fundamentales que se sugieren para tener en cuenta en la educación del siglo XXI. Se mencionan las habilidades y competencias que les permitan a los estudiantes discernir sobre qué tipo de información deberán usar para desempeñarse en mundo en permanente cambio. Debido a la gran cantidad de información disponible y a la multiplicidad de formatos en que pueden ya encontrarla, será tarea primordial del educador desarrollar en sus discentes las habilidades que les permitan navegar con idoneidad en ese vacío de las corrientes informativas. Se parte, de los cuatro “aprendizajes fundamentales” o cuatro pilares de la educación que Jacques Delors propone: Aprender a conocer, aprender a hacer, aprender a vivir juntos y aprender a ser, a las que se le suman tres nuevas competencias en cuanto al ser, de tal forma que se conviertan en una “experiencia global” que permee toda la vida del estudiante
Gobernabilidad del agua en Colombia: dimensiones y contexto
Authors: Correa Assmus Gustavo
Published: September 2018

El presente documento busca establecer la condición de gobernabilidad hídrica nacional con base en eventos empíricos recientes que de al­guna manera se convierten en referentes de eva­luación en torno al desarrollo social. Su método cualitativo se sustenta en el protocolo del análisis global, el cual a su vez se fundamenta en las cua­lidades de la información secundaria presente en contenidos estructurales sobre el objeto de estu­dio, para de allí acercarse desde lo particular ha­cia lo general, y otorgarle al objeto un significado. Los resultados obtenidos desde las dimensiones social, económica, de capacidad política y am­biental evidencian que si bien se han dado avan­ces institucionales de importancia, aún el acceso y tenencia del agua en Colombia reviste proble­máticas que identifican a una gobernabilidad dé­bil, desconectada de la realidad social y la pers­pectiva de su desarrollo, y por consiguiente de una mejor calidad de vida individual o colectiva, desde patrones de equidad y solidaridad.
Meningeal Lymphatic Vessel Flow Runs Countercurrent to Venous Flow in the Superior Sagittal Sinus of the Human Brain
Authors: Kuo Phillip H. , Stuehm Carol , Squire Scott , Johnson Kevin
Published: September 2018

The recent report of the existence of meningeal lymphatic vessels (MLVs) in human and nonhuman primates used both histology and magnetic resonance imaging (MRI). Many questions about the physiology and function of these lymphatic vessels remain unanswered. Through the combination of appropriately positioned saturation bands and time-of-flight angiography sequences, MRI can resolve direction of flow within vessels without the use of exogenous contrast agent. Six healthy volunteers underwent high-resolution MRI of the MLVs running alongside the superior sagittal sinus to determine the direction of the lymphatic flow. In all subjects, the lymphatic flow was posterior to anterior, countercurrent to the direction of venous flow in the superior sagittal sinus and alongside the superior sagittal sinus. This flow strongly supports that a large proportion of the CNS lymphatic flow in humans is directed to the cribriform plate. The countercurrent direction of flow in the MLVs relative to venous flow in the superior sagittal sinus has implications for modeling flow of fluid and solutes across the various compartments of the CNS. A hypothetical compartmental model incorporating countercurrent flow is presented here.
