Background: Transvenous implantable cardiac defibrillators (TV ICD)
provide life-saving therapy for millions of patients worldwide. However,
they are susceptible to several potential short- and long- term
complications including cardiac perforation and pneumothorax, lead
dislodgement, venous obstruction, and infection. The extravascular ICD
(EV ICD) system’s novel design and substernal implant approach avoids
the risks associated with TV ICDs while still providing pacing features
and similar generator size to TV ICDs. Study Design: The EV ICD pivotal
study is a prospective, multi-center, single-arm, non-randomized,
pre-market clinical study designed to examine the safety and acute
efficacy of the system. This study will enroll up to 400 patients with a
Class I or IIa indication for implantation of an ICD. Implanted subjects
will be followed up to approximately 3.5 years, depending on when the
patient is enrolled. Objective: The clinical trial is designed to
demonstrate safety and effectiveness of the EV ICD system in human use.
The safety endpoint is freedom from major complications, while the
efficacy endpoint is defibrillation success. Both endpoints will be
assessed against prespecified criteria. Additionally, this study will
evaluate antitachycardia pacing (ATP) performance, electrical
performance, extracardiac pacing sensation, asystole pacing, appropriate
and inappropriate shocks, as well as a summary of adverse events.
Conclusion: The EV ICD pivotal study is designed to provide clear
evidence addressing the safety and efficacy performance of the EV ICD
System.
Small airway dysfunction is an independent dimension of wheezing disease in preschool children
Authors: Bokov Plamen , Masmoudi Donies , Amat Flore , Houdouin Véronique , Delclaux Christophe
Published: March 2021

Background. Whether small airway dysfunction (SAD), which is prevalent
in asthma, helps to characterize wheezing phenotypes is undetermined.
The objective was to assess whether SAD parameters obtained from
impedance measurement and asthma probability are linked. Methods. One
hundred and thirty-nine preschool children (mean age 4.7 years, 68%
boys) suffering from recurrent wheeze underwent impulse oscillometry
that allowed calculating peripheral resistance and compliance of the
respiratory system (markers of SAD) using the extended RIC model
(central and peripheral Resistance, Inertance and peripheral Compliance
of the respiratory system). Children were classified using the
probability-based approach of GINA guidelines (few, some, most having
asthma). A principal component analysis (PCA) that determined the
dimensions of wheezing disease evaluated the links between SAD and
asthma probability. Results. Forty-seven children belonged to the few,
28 to the some and 64 to the most having asthma groups. Whereas their
anthropometrics and measured parameters were similar, the most having
asthma group exhibited the lowest mean value of airway inertance after
bronchodilator probably due to airway inhomogeneities. PCA characterized
nine independent dimensions including a peripheral resistance
(constituted by baseline peripheral resistance, AX, R5-20Hz, X5Hz), a
central resistance (baseline central resistance, R20Hz) and an airway
size dimension (post-bronchodilator inertance and central resistance).
PCA showed that the SAD markers were independent from clinical
dimensions (control and asthma probability were two other dimensions)
and did not help to define wheezing phenotypes. Conclusions. Lung
function parameters obtained from impulse oscillometry and asthma
probability were belonging to independent dimensions of the wheezing
disease.

Published: March 2021

Background: A series of repeated questionnaire surveys among 8- and
9-year-old schoolchildren in the city of Patras, Greece, demonstrated a
continuous rise in the prevalence of wheeze/asthma from 1978 to 2003,
with a plateau between 2003 and 2008. We further investigated
wheeze/asthma trends within the same environment during the last decade.
Methods: Two further identical cross-sectional surveys were conducted in
2013 (N=2554) and 2018 (N=2648). Physician-diagnosed wheeze and asthma
were analysed separately and in relation to their occurrence
(recent-onset: solely within the last two years; non-current: prior to
the last two years; persistent: both before and within the last two
years). In addition, in 2018, spirometry was performed in participants
reporting relevant symptoms and in a random sample of healthy controls.
Results: The prevalence of current wheeze/asthma declined from 6.9% in
2008 to 5.2% in 2013 and 4.3% in 2018. The persistent and non-current
wheeze/asthma groups (both including children with symptoms at preschool
age) followed this overall trend, while the prevalence of recent-onset
wheeze/asthma remained unchanged. Persistent and non-current wheezers
were also more frequently diagnosed with asthma, in contrast to those
with recent-onset wheeze. Children with recent-onset wheeze/asthma and a
considerable fraction of those with persistent symptoms had lower lung
function. Conclusions: The prevalence of childhood wheeze/asthma has
declined significantly during the last decade in Greece. Our analysis
suggests that the reversing trend is most likely attributed to changing
asthma perceptions among physicians and/or parents, especially in the
case of preschool children with troublesome respiratory symptoms.

Jatio Sangsad Bhaban: Aspiring to be a UNESCO World Heritage Site
Authors: Choudhury Bayezid Ismail
Published: March 2021

The Jatio Sangsad Bhban (JSB) or the National Assembly Building of Bangladesh is an internationally renowned architectural masterpiece designed by eminent 20th-century American architect Louis I. Kahn. Its unique Architectural merit makes it one of the most significant buildings of the 20th century. The impact of this iconic building encompasses all spheres of Bengal life including culture, heritage, ethos and lifestyle. Its architectural values also evoke national identity, symbolizing the hopes and aspirations of the people of Bangladesh. However, despite its international and national material, social and human significance, it is yet to be nominated as a UNESCO World Heritage Site (WHS). This paper argues for the potential of the JSB to become a WHS.

Published: March 2021

The cytotoxicity of amorphous calcium phosphate (ACP) and chitosan lactate (ChOL) multifunctional and hybrid composite coatings on MRC-5 human lung fibroblast cell line was elucidated. ACP/TiO2 and ACP/TiO2/ /ChOL were deposited onto Ti by a novel in situ anodization/anaphoretic process at constant voltage. Cytotoxicity tests showed that there was no significant decrease in the survival of healthy MRC-5 cells exposed to composite samples without chitosan lactate, while there was an increase in the number of viable cells in the sample containing ChOL. These findings show that there was improved cell proliferation, differentiation and cell viability in the ChOL-containing sample, which makes ACP/TiO2/ChOL coating a good candidate for applications in medicine and stomatology.

Published: March 2021

The stochastic P-bifurcation behavior of bi-stability in a generalized Van der Pol oscillator with a fractional damping under multiplicative Gaussian white noise excitation is investigated. Firstly, using the principle of minimal mean square error, the non-linear stiffness terms can be equivalent to a linear stiffness which is a function of the system amplitude, and the original system is simplified to an equivalent integer order Van der Pol system. Secondly, the system amplitude?s stationary probability density function is obtained by stochastic averaging. Then according to the singularity theory, the critical parametric conditions for the sys-tem amplitude?s stochastic P-bifurcation are found. Finally, the types of the system?s stationary probability density function curves of amplitude are qualitatively analyzed by choosing the corresponding parameters in each area divided by the transition set curves. The consistency between the analytical results and the numerical results obtained from Monte-Carlo simulation verifies the theoretical analysis in this paper and the method used in this paper can directly guide the design of the fractional order controller to adjust the response of the system.

Leader Effects in Competition among Teams: Evidence from a Field Intervention
Authors: Casas-Arce Pablo , Martínez-Jerez F. Asís
Published: March 2021

This paper investigates whether leadership style moderates the effect of leader incentives on the performance of teams. In collaboration with a Latin-American bank, we engineered a field experiment by designing a series of contests among the bank branches with varying prize structures. We find evidence that providing explicit incentives to team leaders has a positive effect on team performance. However, the effect of incentives differs based on the manager's leadership style and team characteristics. Leader incentives are less effective for managers who inspire their team by appealing to higher values than for managers who motivate performance through rewards and penalties.

PENALAAN OPTIMAL KONTROLER PSS-PID PADA SISTEM SINGLE MACHINE INFINITE BUS MENGGUNAKAN ANT COLONY OPTIMIZATION
Authors: Djalal Muhammad Ruswandi , Kadir Nasrun
Published: March 2021

Perubahan beban pada sistem tenaga listrik secara tiba-tiba menyebabkan terjadinya gangguan dinamik. Gangguan tersebut menyebabkan kestabilan generator terganggu, karena generator tidak merespon gangguan tersebut secara cepat. Hal ini menyebabkan terjadinya osilasi pada generator berupa osilasi frekuensi dan sudut rotor. Salah satu peralatan kontrol tambahan yang mampu meningkatkan kestabilan suatu generator adalah Power Sistem Stabilizer (PSS) dan Proportional Integral Derrivative (PID). Dalam aplikasinya, penentuan parameter kontroler ini masih menggunakan metode trial & error, metode ini sangat sulit untuk mendapatkan parameter yang tepat. Dengan menggunakan metode cerdas berbasis Ant Colony didapatkan parameter PSS-PID yang optimal. Dengan penalaan optimal didapatkan respon frekuensi dan sudut rotor sistem SMIB yang optimal, ditunjukkan dengan respon overshot sistem yang minimum. Kontroler mampu memberikan kestabilan sehingga osilasi overshoot dapat diredam, serta kinerja settling time yang semakin cepat untuk sistem menuju ke kondisi steady state. Untuk menguji kestabilan sistem SMIB digunakan studi kasus penambahan dan pengurangan beban, dengan metode kontrol yang diusulkan PSS-PID yang dioptimasi menggunakan Ant Colony.

Objective Tetralogy of Fallot (TOF) usually presents with a large non-restrictive ventricular septal defect (VSD). Case(s) We hereby report a rare case of prenatal diagnosis of TOF with a restrictive VSD secondary to redundant tricuspid valve tissue. Partial occlusion of the VSD resulted in prenatal progression to myocardial hypertrophy and postnatally to right heart failure with difficult management. Conclusion Prenatal signs of cardiac dysfunction in TOF should prompt a detailed exam of the VSD. Parents and neonatologists must be advised and delivery must be guaranteed in a tertiary center.
Variations in the integral amplification of of seismic ground motions on the territory of Kiev
Authors: Kendzera A. , Semenova Yu.
Published: March 2021

The relevance of the research and the results presented in the article is due to the need to provide the designers of seismic-resistant construction with maps of seismic zoning of settlements and agglomerations on the territory of Ukraine in the amplitude parameters of seismic ground motions. An analytical-empirical approach to mapping is proposed on the example of the territory of Kyiv, which can be implemented in conditions of an insufficient number of results of instrumental seismological observations. This approach gives positive results provided that the territory is well studied in geological terms. Within the territory of Kyiv, using the method of seismic-geological analogies, areas (taxonometric zones) have been identified that are homogeneous in response to seismic effects. For all taxonometric zones, seismic-geological models of the soil strata were built and their spectral characteristics were calculated taking into account the nonlinear deformation of the soil. The averaged frequency response was also calculated for the ground conditions of the territory of Kyiv as a function of the distribution of the average values of the spectral amplification of seismic oscillations in frequency for all zones. A map of the distribution of the deviation of the integral amplification of seismic vibrations from the average value for the territory of Kyiv was constructed. It is proposed to use a spectral amplification map to determine the values of the calculated relative ground acceleration of the investigated site when using the spectral method for calculating the emergency combination of loads taking into account the seismic effect. The map of the distribution of the deviation of the integral amplification of seismic oscillations from the average value for the territory of Kyiv is an intermediate stage in the construction of seismic zoning maps for Kyiv in amplitude terms of ground motions.
Digital vector of Ukraine development: formation of national industry of oceanographic geospatial data
Authors: Shchyptsov О.A.
Published: March 2021

A step-by-step deployment of work on the creation of a national geospatial data infrastructure within the digital development of Ukraine is considered. The goals of mentioned infrastructure are as follows: provision of the open access to data, in particular the data and knowledge of scientific researches and observations; involvement of the national oceanographic scientific community in the global network of “big data”, further commercialization of research results, creation of innovations, digital products and services.
The digital industry of oceanographic geospatial data is expected to become one of the components of the national digital geospatial data infrastructure. It will primarily cover the oceanography, considering the scale and complexity of hydrophysical processes in the oceans, the multifaceted impact and use of data for the sustainable development and economic activity; as well as conceptually modernize data production and disposal.
The article presents an analysis of the Law on the National Infrastructure of Geospatial Data regarding the provisions that have to be fulfilled by the holders of oceanographic data.
Considering that in accordance to the Law the national geospatial data infrastructure does not cover the entire array of collected oceanographic data, additional preparatory measures are proposed for the formation of a modern infrastructure and digital industry of oceanographic data.
Creation of a modern digital industry of oceanographic data requires concerted efforts and consolidated actions of the state, scientific community, business entities and interested civil society. Its creation will ensure an appropriate level of participation and form a positive image of Ukraine in the framework of the United Nations Decade of Ocean Science for Sustainable Development (2021—2030).

Using English to teach and learn academic subjects in higher education (HE) across the globe is increasing in popularity. The overarching aim of this study is to examine the impact of English-medium instruction (EMI) on Omani engineering students’ academic performance and their studies in an English-medium engineering programme in Oman. This paper reports on findings from a larger project that was intended to investigate Omani engineering students’ experience of learning through the medium of English in one of the Colleges of Technology in Oman. The study adopted a qualitative interpretative approach with a case study strategy and a purposive sampling technique to look into the impact of EMI on Omani engineering students’ academic performance and their studies. The sample included 12 Omani engineering and 8 engineering instructors who were interviewed along with five classroom observations. The data were collected and generated through semi-structured interviews and classroom observations. They were analysed manually, inductively and thematically using Braun and Clarke’s model (2006). The findings showed that EMI had both positive and negative impacts on the students’ academic performance and their studies.
The Syntax of Multiple Determination in Arabic: An anti- residual relative clause/close-apposition account
Authors: Jarallah AlQahtani Saleh
Published: March 2021

This paper aims to give an account of the multiple determination (determiner spreading) phenomenon in Arabic. Determiner spreading is the syntactic representation and phonological realization of multiple determiners within the same determiner phrase. As a cross-linguistic phenomenon, determiner spreading has been investigated in other languages (e.g., Scandinavian and Greek); different accounts have been proposed. For Scandinavian languages, determiner spreading has been analyzed as a representation of different semantic interpretations. As far as Greek is concerned, some analyses have been proposed; however, two prominent ones have received considerable attention in the literature: (i) a residue of a reduced relative clause and (ii) an instantiation of close appositions. Contrary to those analyses, this paper claims that none of the two analyses is suitable for Arabic; thus, a language-specific analysis is required. To analyze determiner spreading in Arabic, the current paper posits the following research question: What is the linguistic purpose of the multiple determiners found in Arabic determiner phrases? Answering the research question, the paper claims that, in addition to its indispensable role in establishing agreement between nouns and adjectives within the Arabic determiner phrase, determiner spreading demarcates syntactic and semantic phrase boundaries. The paper takes Minimalist Program and Distributed Morphology as a theoretical framework to argue that attributive adjectives are projection of an agreement phrase headed by the definite article ʔal or by the indefinite phonological marker `nunation: -n’. This proposal requires no syntactic movements in the syntax proper. The ultimate linear order is achieved in the phonological components.

Authors: Alenezi Saud
Published: March 2021

Reading is an essential strategic and a life-long skill required for success in learning. The current study explores the knowledge and beliefs of Saudi students of English as a foreign language (EFL) about English reading comprehension strategies. It also intends to determine if there is a significant correlation between the students’ foundational knowledge of English reading comprehension strategies and their beliefs about reading comprehension strategies. The study employed a quantitative method. The data were collected using a forty-item survey questionnaire. The respondents were 203 Saudi EFL students enrolled in Preparatory Year Program at Northern Border University in Saudi Arabia. The data collected were analyzed using descriptive statistics to determine frequency, percentage, mean, standard deviation, and a test of non-parametric correlation (Spearman’s rho correlation coefficient) was run to determine the relationship between the variables. The overall findings of the study revealed that the students have a good foundational knowledge of pre-reading, while-reading, and post-reading reading strategies. The correlational analysis showed a medium correlation between students’ foundational knowledge of reading strategies and their beliefs about reading strategies. In conclusion, the study suggests some implications for teaching English reading to EFL students.

The Effects of Situational and Perceived Interest on EFL Reading Comprehension: A Gender-Based Study at the University of Algiers 2
Authors: Akhrib Mohammed , Zohra Mebtouche Nedjai Fatma
Published: March 2021

This study aims to investigate gender differences in English as a foreign language (EFL) reading comprehension, situational and perceived interest for gender-oriented passages. It also examines whether any gender variances in situational or perceived interest in those passages cause gender differences in EFL reading comprehension. Throughout this research, clear insights about individual differences and the unexplained variance in foreign language reading are provided. Two main research questions were formulated: (a) Do gender differences in EFL students’ situational interest explain gender differences in EFL students’ reading comprehension? (b) Do gender differences in EFL students’ PI explain gender differences in EFL students’ reading comprehension? In this concern, EFL freshmen students at the University of Algiers 2, including 35 females and 24 males, were conveniently selected. The selected materials were two tests of reading comprehension with male and female texts. Each of these tests was followed by the questionnaires of sources of interest and perceived interest, adapted from Brantmeier (2006). Findings revealed significant gender differences in tests with male and female passages. Besides, significant gender differences found in cohesion, prior knowledge, ease of recollection, and perceived interest for both male and female passages in addition to engagement for the female text did not account for gender differences in reading comprehension of their respective tests. In this way, other factors than situational and perceived interest would explain gender differences in reading comprehension.

La era de las redes: servicios públicos, grandes empresas y finanzas internacionales en las ciudades mexicanas a principios del siglo XX
Authors: Martínez Delgado Gerardo
Published: March 2021

En la primera década del siglo XX hubo en México las condiciones para la formación y aplicación de grandes capitales nacionales y extranjeros dedicados a la construcción de infraestructura o prestación de servicios públicos en un conjunto muy amplio de ciudades. Se trató de un momento clave en la historia económica y empresarial, en la historia urbana y también en la historia de la tecnología: fue la era de las redes financieras, las redes de servicios públicos y la expansión empresarial. El texto estudia la concentración empresarial que ocurrió en estos años, poniendo especial atención en la Compañía Bancaria de Fomento y Bienes Raíces y en los intereses del empresario Enrique Schöndube, pero también en las compañías de Weetman Pearson y en The Mexican Light and Power Company, ponderando su importancia frente a otras que tuvieron menores alcances. Se sigue su proceso de creación y las reglas de expansión capitalista en las que se inscribía su acción; para explicar los cambios ocurridos a nivel urbano y económico, se analizan sus mecanismos de operación, su diversificación de intereses, sus conexiones internacionales y su relación con otras empresas. Al final, se miden sus alcances, se esbozan los nuevos escenarios que surgieron para las empresas a raíz del estallido de la revolución mexicana y, sobre todo, se reflexiona sobre el escenario en que quedaron las ciudades mexicanas para cumplir con el proyecto de instalar en ellas redes de servicios. A partir del seguimiento bibliográfico de casos particulares, de documentación oficial y privada, series estadísticas, hemerografía, entre otras fuentes, se abona al conocimiento de historias empresariales importantes y se articulan líneas de interpretación comparativa que permiten ofrecer una versión más acabada sobre el conjunto de ciudades mexicanas y sobre la presencia de redes, ya de servicios, ya de empresas o finanzas, ya de técnicos, tecnologías y agentes.

Published: March 2021

Some preliminary results of joint research lexicographic project of Russian and Kazakh linguists on linguo-cultorological contrastive analysis of Russian-Kazakh phraseological correlations are discussed in the article. The work presents the experience of contrastive lexicographic description of the concepts ZHAN - DUSHA (“SOUL”) and DENE / BOY - TELO (“BODY”) in the aspect of their language objectification in Russian and Kazakh phraseologisms. The purpose is to give contrastive analysis of the opposite concepts ZHAN - DUSHA (“SOUL”) and DENE / BOY - TELO (“BODY”) in their phraseological representation in Russian and Kazakh. The material for the study is the data of Russian and Kazakh phraseological dictionaries. The theoretical basis of the work is the ideas of language conceptualization of the world, the principles cognitive interpretation of elements of “a language of culture” and the methodology of linguo-cultorological study in phraseologisms. The standard method of conceptual analysis and the method of contrastive phraseological analysis are used un the article. It is shown that there are a lot of substantial resemblances in phraseological representations of the concepts in Russian and Kazakh lingual cultures resulting from general principles of language conceptualization of reality in languages of the world. On the other side, some conceptual divergences between compared languages are also revealed: they are caused by peculiarities of nature and culture environment as well as by diversity in changing of nominations for imaginative denotation of approximately analogous substance. The authors come at a conclusion that the contrary concepts ZHAN - DUSHA (“SOUL”) and DENE / BOY - TELO (“BODY”) are revealed in the mirror of each other in phraseology of compared languages.
Variability and Difficulty in Translating Interjections (based on Russian and Kabardino-Circassian Languages)
Authors: Afaunova (Tokova) A. A.
Published: March 2021

The results of a comparative analysis of translated Russian texts of literary works with their original in the Kabardino-Circassian language are presented. Special attention is paid to the problems of translating interjections from one language into another. It is proved that the translator must have knowledge of the grammatical structure of the translated material and take into account the slightest semantic shades of words. Our observations revealed the features of borrowing interjections from the Russian language into Kabardian speech, which, assimilating, become part of linguistic culture. The novelty of the work is seen in the fact that in Kabardino-Circassian linguistics there are no scientific works devoted to the problems of translation of interjections. All available publications concerning this subject are literary. The relevance of the work is due to the need to improve the system of approaches to the translation of interjection units, since they are not taken into account by translators in due measure. A phonetic-morphological classification of methods for translating interjections is proposed in the article. It is proved that for an adequate and accessible translation of interjections as such, knowledge from the fields of phonetics, morphology, and semantics is most important.
Organization of elections among the native and foreign population in the first State Duma
Authors: Andreev A. A.
Published: March 2021

The study is devoted to the elections to the first Russian parliament among the representatives of the so-called “native” and “foreign” population of the Russian Empire. It is shown that in the conditions of the revolutionary events of 1905-1906 at the highest bureaucratic level for Russian absolutism, the fundamental issue was the issue of delegating part of the legislative initiative to elected representatives of society. It is noted that under pressure from local administrations - the Turkestan Governor-General and Caucasian Viceroyalty - it was decided to entrust voting right in a truncated form to the peoples of the Caucasus (Caucasian Viceroyalty), Turkestan Territory (Semipalatinsk Oblast), the Steppe Territory and the nomadic foreigners of Russian provinces and regions. It is indicated that a comparative analysis of official documentation on elective production and periodicals on the outskirts allows us to consider in detail the very process of the first elections, its differences and similarities in parts of the empire. The author concludes that the election rules proposed by the center made it possible for people who are not connected with the local administration to be represented by their people in the first State Duma. The analysis of the biographies of the candidates showed that the ethnic factor played a greater role than their political views.

Formalismo variacional en el modelado y control de sistemas de levitación magnética
Authors:   , Jara González Victor Rolando
Published: March 2021

In this thesis he addressed the controlled Lagrangian control technique in two magnetic levitation systems, these being the fundamental object of study. An analysis of the natural dynamics of three mechanical systems was made; a simple pendulum, two pendulums attached to a xed beam and an inverted pendulum on a cart, which served to understand from a physical-mathematical point of view the presentation of the Lagrangian formalism. This analysis in mechanical systems was the basis in the study of the natural dynamics of the magnetic levitation systems treated. A geometrical stability analysis was also carried out, both for the mechanical systems and for the magnetic levitation systems; this constitutes the rst novelty as a result of the work. The presentation of the controlled Lagrangian control technique was explained in detail, taking as an example the inverted pendulum system on the cart, to later be implemented in magnetic levitation systems. The results obtained were satisfactory, demonstrating with them that this control technique makes sense in magnetic levitation systems, until now simple. From the mathematical point of view, the establishment of a control law in these magnetic levitation systems guarantees their stability in the understanding that the controlled dynamics will be equal to the desired one.
