Comparing Calculated and Measured Losses in a Satellite-Earth Quantum Channel
Authors: Galambos Máté , Bacsárdi László
Published: December 2020

Long distance distribution of quantum states is necessary for quantum communication and large scale quantum experiments. Currently this distance is limited by channel loss. Previous theoretical analisys and proof of concept experiments showed that satellite quantum communication may have lower losses than optical cable based counterparts. Recently the QuESS experiment [3] realized the first satellite-Earth quantum channel. In this paper we compare heoretical predictions of different mathematical models with experimental results regarding channel loss. We examine the HV-5/7 model, HV-Night model and Greenwood model of optical turbulences, the geometric [4] and diffraction [5][6] models of beam wander and beam widening. Furthermore we take into account the effect of atmospheric gases and aerosols as well as the effect of pointing error. We find that theoretical predictions are largely in the same order of magnitude as experimental results. The exception is the diffraction model of beam spreading where our calculations yielded only one tenth of the measured value. Given the ever changing nature of weather conditions and the changing composition of atmospheric aerosoles we conclude that calculated and measured losses are in good agreement.
Ontology based Indoor Navigation Service for the ILONA System
Authors: Kun Dániel Péter , Baksáné Varga Erika , Tóth Zsolt
Published: December 2020

An ontology based way finding algorithm is presented in this paper that allows route generation between two separate parts of an indoor environment. The presented ontology provides a flexible way to describe and model the indoor environment, in addition it fits and extends the existing model of the ILONA System. Ontology reasoners provide an efficient way to perform complex queries over the knowledge base. The instances, that are queried by the reasoner, are used to initialize the graph which represents an indoor environment. Due to parameterization of the reasoner, different graphs can be generated from the ontology which makes the way finding algorithm flexible. Thus, the task of indoor way finding was converted into a well-known graph search problem. Dijkstra’s shortest path algorithm is used for route generation in the graph yielded. The algorithm was implemented and tested in the ILONA System and its functioning is demonstrated by real-life scenarios.

Assessing Tunisian Tourism Development Policy Parameters Using Participatory Systems Mapping
Authors: Halioui Salma , Kamath Vasanth , Woosnam Kyle M.
Published: December 2020

Using a mixed-methods approach, this article explores various issues related to tourism development in Tunisia. It also presents a system dynamics (SD) simulation model using a participatory system mapping (PSM) framework. Following the Arab Spring in 2011, and subsequent terror attacks in 2015, the Ministry of Tunisian Tourism has been pursuing destination image restoration strategies to revive the sector. We attempt to identify the key policy levers that can help to achieve destination image restoration using PSM; to do so, we formulated a model and analyzed it using SD. We conclude that controlling terror attacks and focusing on providing alternate holiday options represent policy levers that can significantly restore the image of Tunisia. This research will enable policymakers to identify the influences of feedback loops in the system and work towards a viable strategy.

Modern holiday culture of Russia: preservation Russian traditions, constructing new symbols and meanings
Authors:   Siberian Branch of the Russian Research Institute of Cultural and Natural Heritage named after D.S.Likhachev, Zolotova Т. N.
Published: December 2020

The article is devoted to identifying Russian ethnic traditions and symbols that are preserved in the holiday calendar of modern Russia. Most attention is paid to such holidays as Christmas, Epiphany, Russia day and national unity day. Conclusions are made about the preservation, revival and transformation in the public life of a private celebratory customs on semantic convergence of the notions “Russian” and “Orthodox”, established in the public consciousness and social practice new social and political holidays thanks to their chronological overlay on the traditional advent calendar and the activities of cultural institutions due to the needs of the state in strengthening the ideological component of the holidays and strengthening of the unity of the nation. The popularity and mass character of holidays is influenced by the spread of modern forms of communication — television and the Internet with a variety of content and social networks that form a kind of “fashion” in society to follow certain customs. Strengthening consumer psychology and ignoring cultural traditions lead to a functional imbalance in the festive and ceremonial sphere, so it is necessary to take care of the historical and cultural heritage and design new images and meanings.

The nature of this ability is rooted in the specifics of Russian Orthodoxy, organically linked to Slavic pre-Christian culture.
Natural resources management of the Russian population in Altai during the XVIII – first half of the XIX centuries
Authors:   Tyumen State University, Turov S. V.
Published: December 2020

The adaptation of the Russian traditional industrial structure to the natural environments of the region is analyzed. Agriculture was propelled by the relief and microclimate’s particular qualities. Trade pressure on the animality and plant life was predicated upon economic needs and market conditions. There is a regional specialization in collecting wild herb and in hunting animals. Trade activity had an impact on the animal numbers and the forests health. The inclusion of natural features in the range of trade interests of the peasantry depended on many factors. In general, the high adaptation level of the Russian traditional industrial structure to the natural conditions of the region should be recognised.

Factors of adaptation of Mordovian settlers in the south of Western Siberia in the late 19th — early 20th centuries
Authors:   Novosibirsk State Museum of Local Lore, Ovcharova M. A.
Published: December 2020

The article will focus on the significance of the agrarian movement of people from the European part of Russia to Siberia in the late 19th — early 20th centuries. A stream of ethnoculturally diverse people poured into Siberia. Different ethnic groups in different, sometimes unusual natural conditions were forced to adapt to the surrounding reality. All this happened by changing the usual ways of managing and living. This naturally influenced the formation of a new way of life, changes in cultural traditions that absorbed the traces of a new environment, mixed with the «established» centuries. Thus, at times, the settlers developed a new adaptation culture.
Post-Soviet practices of (re)production of ethnicity among the indigenous peoples of Western Siberia
Authors:   Institute of Ethnology and Anthropology RAS, Рivneva E. A.
Published: December 2020

How do people create a social environment for maintaining their ethnic identity outside of the «traditional» way of life, in conditions of «asymmetric” interaction with theother cultural majority? This issue is investigated in the article on the example of the Khanty-Mansiysk Autonomous Okrug — Yugra. It is concluded that today, in the context of the loss of many objective cultural characteristics, the ethnicity of the indigenous minorities is supported through the allocation of specialized types of intellectual labor and the corresponding social institutions which maintain preservation, production and transmission of ethnocultural specificity
Discrete Type SIR Epidemic Model with Nonlinear Incidence Rate in Presence of Immunity
Authors: Parvin Tahera , Islam Ariful , Kumar Mondal Pankaj , Biswas Haider Ali
Published: December 2020

Mathematical modeling is very important to describe the dynamic behavior of biological and biomedical systems. The SIR model is the most common mathematical model of epidemics. An epidemic occurs if the number of people infected with a disease is increasing in a population. A numerical discretization for an SIR epidemic model is discussed, where the incidence rate is assumed to be Beddington-DeAngelis type. In particular, we reconsider a SIR epidemic model with Non Linear incidence and treatment rate derived by (Dubey et al. 2015) [1]. We applied Euler method to discretize this model. This discretization leads to a numerical scheme which can be considered as a discrete system. Then we analyzed the dynamics of the obtained discrete system. We developed the model with the focus on the concentration of the basic reproduction number and related stability analysis for the disease-free and endemic equilibrium points. Finally, We have performed numerical simulations to illustrate the disease behavior

The Quaid Azam Muhammad Ali Jinnah in Arabic Literature
Authors: Elahi Uzma , Yaqoob Khan Marwat
Published: December 2020

Contacts and relations between Arabs and subcontinent are primitive. When Islam was spread and the Islamic state was extended to this region. The subcontinent was enlightened by Islam and was cultured by its civilization. The residents of the Indian subcontinent were impressed by Arabs and their civilization and culture and as a result, wrote many books in the Arabic language in different fields. The impact of all this is that the residents of the subcontinent were highly influenced with the Arabs but as we know these influences and impacts between the two kinds of literature were not only from one side, indeed a mutual exchange of influences occurred. Arab writers and poets wrote many books and eulogies about Pakistan its problems its cities and its famous personalities like Muhammad Ali Johar, Allama Muhammad Iqbal, and Muhammad Ali Jinnah, etc.    

This study attempts to employ descriptive, comparative and analytical survey of Arabic works focusing on the life and struggles of Muhammad Ali Jinnah. This study also highlights the misconceptions found in literary works of Arab Scholars about historical facts concerned with the political history of Muhammad Ali Jinnah.
Family Courts in Pakistan:
Authors: Siddique Hafiz Muhammad , Badshah Syed Naeem
Published: December 2020

Family law in Pakistan underwent a fundamental change when the Family Courts Act, 1964 was enacted and family matters were entrusted to family courts instead of ordinary civil courts. Since then, family courts have been administering family law to provide ‘better remedies’ to women and children. This paper aims to highlight the objectives of enacting Family Courts Act 1964 and how does it regulate its own proceedings under the judicial structure. It is significant to examine that the provisions of (Civil Procedure Code, 1908) CPC are generally not applicable to the trials before family courts, however usually proceedings are more or less the same; yet, family courts have special powers to discover the possibilities of amicable settlement of family disputes. This paper investigates various procedures in several family issues like a suit for maintenance, dissolution of marriage, a suit for dower and other dowry articles, inheritance and custody of children. It also interrogates that how far the objectives of the said law are achieved? I also argue that there is a dire need of establishing family courts separately like other administrative tribunals as the spirit of the law demands. This research mainly emphasizes that the environment of the courts should be segregated for the decorum of the families whose domestic disputes are usually exposed publically that I cite as a great reason for not accessing legal protection in Pakistani society. The paper also stresses that the milieu of the courts should also be affable for the visit of the child for the best interest and welfare of children and women.

The Wide-field VLBA Calibrator Survey: WFCS
Authors: Petrov Leonid
Published: December 2020

This paper presents the results of the largest very long baseline interferometry (VLBI) absolute astrometry campaign to date of 13,645 radio source observations with the Very Long Baseline Array. Of these, 7220 have been detected, including 6755 target sources that have never been observed with VLBI before. This makes the present VLBI catalog the largest ever published. The positions of the target sources have been determined with the median uncertainty of 1.7 mas, and 15,542 images of 7171 sources have been generated. Unlike previous absolute radio astrometry campaigns, observations were made at 4.3 and 7.6 GHz simultaneously using a single wide-band receiver. Because of the fine spectral and time resolutions, the field of view was 4′–8′—much greater than the 10″–20″ in previous surveys. This made possible the use of input catalogs with low position accuracy and the detection of a compact component in extended sources. Unlike previous absolute astrometry campaigns, both steep- and flat-spectrum sources were observed. The observations were scheduled in the so-called filler mode to fill the gaps between other high-priority programs. This was achieved by the development of the totally automatic scheduling procedure.
Architectures of Exoplanetary Systems. II. An Increase in Inner Planetary System Occurrence toward Later Spectral Types for Kepler’s FGK Dwarfs
Authors: He Matthias Y. , Ford Eric B. , Ragozzine Darin
Published: December 2020

The Kepler mission observed thousands of transiting exoplanet candidates around hundreds of thousands of FGK dwarf stars. He et al. applied forward modeling to infer the distribution of intrinsic architectures of planetary systems, developed a clustered Poisson point process model for exoplanetary systems (SysSim) to reproduce the marginal distributions of the observed Kepler population, and they showed that orbital periods and planet radii are clustered within a given planetary system. Here, we extend the clustered model to explore correlations between planetary systems and their host-star properties. We split the sample of Kepler FGK dwarfs into two halves and model the fraction of stars with planets (0.5–10R⊕and 3–300 days),fswpa, as a linear function of the Gaia DR2 color. We confirm previous findings that the occurrence of these planetary systems rises significantly toward later-type (redder) stars. The fraction of stars with planets increases fromfor F2V dwarfs tofor mid-K dwarfs. About half () of all solar-type (G2V) dwarfs harbor a planetary system between 3 and 300 days. This simple model can closely match the observed multiplicity distributions of both the bluer and redder halves in our sample, suggesting that the architectures of planetary systems around stars of different spectral types may be similar aside from a shift in the overall fraction of planet-hosting stars.
Kinetic Simulations of Cosmic-Ray-modified Shocks. II. Particle Spectra
Authors: Caprioli Damiano , Haggerty Colby C. , Blasi Pasquale
Published: December 2020

Diffusive shock acceleration is a prominent mechanism for producing energetic particles in space and in astrophysical systems. Such energetic particles have long been predicted to affect the hydrodynamic structure of the shock, in turn leading to CR spectra flatter than the test-particle prediction. However, in this work along with a companion paper, we use self-consistent hybrid (kinetic ion–fluid electron) simulations to show for the first time how CR-modified shocks actually produce steeper spectra. The steepening is driven by the enhanced advection of CRs embedded in magnetic turbulence downstream of the shock, in what we call the “postcursor.” These results are consistent with multiwavelength observations of supernovae and supernova remnants and have significant phenomenological implications for space/astrophysical shocks in general.

plane at various galactocentric radii are remapped to the R − Z plane, the spiral can explain well the observed asymmetric velocity substructures. This is evidence that the phase spiral features are the same as the bulk motions found in previous work as well as this work. Test particle simulations and N-body simulations show that an encounter with a dwarf galaxy a few hundred million years ago will induce a perturbation in the galactic disk. In addition, we find that the last impact of Sgr dSph can also contribute to the flare. As a consequence of the encounter, the distribution function of disk stars at a large range of radii is imprinted by the gravitational perturbation.

Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types. The most common end points of stellar evolution are no exception, as debris disks have been observed around several dozen white dwarf stars. But instead of planetary formation, post-main-sequence debris disks are a signpost of planetary destruction, resulting in compact debris disks from the tidal disruption of remnant planetesimals. In this work, we present the discovery of five new debris disks around white dwarf stars with gaseous debris in emission. All five systems exhibit excess infrared radiation from dusty debris, emission lines from gaseous debris, and atmospheric absorption features indicating ongoing accretion of metal-rich debris. In four of the systems, we detect multiple metal species in emission, some of which occur at strengths and transitions previously unseen in debris disks around white dwarf stars. Our first year of spectroscopic follow-up hints at strong variability in the emission lines that can be studied in the future, expanding the range of phenomena these post-main-sequence debris disks exhibit.

Bicortical drilling of the clavicle is associated with risk of iatrogenic damage from plunging given the close proximity of neurovascular structures. This study determined plunge depth during superior-to-inferior clavicle drilling using a standard drill vs drill-sensing technology. Two orthopedic surgeons drilled 10 holes in a fresh cadaveric clavicle with drill-sensing technology in freehand mode (functions as standard orthopedic drill) and another 10 holes with drill-sensing technology in bicortical mode (drill motor stops when the second cortex is breached and depth is measured in real time). The drill-measured depths were compared with computed tomography–measured depths. Distances to the neurovascular structures were also measured. The surgeons' plunge depths were compared using an independent
t
test. With freehand (standard) drilling, the mean plunge depth was 8.8 mm. For surgeon 1, the range was 5.6 to 15.8 mm (mean, 10.9 mm). For surgeon 2, the range was 3.3 to 11.0 mm (mean, 6.4 mm). The surgeons' plunge depths were significantly different. In bicortical mode, the drill motor stopped when the second cortex was penetrated. Drill-measured depths were verified by computed tomography scan, with a mean difference of 0.8 mm. Mean distances from the clavicle to the neurovascular structures were 15.5 mm for the subclavian vein, 18.0 mm for the subclavian artery, and 8.0 mm for the brachial plexus. Plunge depths differed between surgeons. However, both surgeons' plunge depths were greater than distances to the neurovascular structures, indicating a risk of injury due to plunging. Although a nonspinning drill bit may still cause soft tissue damage, drill-sensing technology may decrease the risk of penetrating soft tissue structures due to plunging. [

Making Metallic Thin Films Atomically Flat
Authors: KIM Su Jae , CHEON Miyeon , JEONG Se-Young
Published: December 2020

Can we control the flatness of the surface of a thin film down to the level of individual atoms? Can we further make such an ultraflat surface on a wafer scale? For such purposes, the current deposition methods, including molecular beam epitaxy (MBE), atomic layer deposition (ALD) and conventional sputtering methods, are still not adequate. In this article, we introduce a novel thin film deposition technique developed by modifying a simple sputtering method to make atomically flat metallic surfaces and a new way to investigate the structural details of thin films grown at the atomic level. For thin film, heteroepitaxial growth of a crystalline film on a different crystalline substrate is usual, and the lattice mismatch between the crystalline film and the substrate occurring in heteroepitaxy produces many misfits at the interface, which create various defects, including dislocations and grain boundaries that eventually lead to a rough surface and the deterioration of the overall quality of the crystal. The metamorphic growth method utilizing the extended atomic distance mismatch (EADM) helps to achieve successful growth of thin films in spite of a large lattice mismatch by calculating the match for a relatively long period in advance. Having an ultraflat surface for thin films made of metals such as copper has many advantages. Several advantages and possible applications of metal thin films with ultraflat surfaces are introduced.
Vocationalizing Education
Authors: Khoza Sammy
Published: December 2020

Technical and vocational education and training (TVET) colleges continue to struggle to fulfill their mandate of skills development among the youth. This is so because TVET colleges still lag behind in integrating information and communications technology (ICT) in their classrooms, which has made inroads in industries. Qualitative approach was used to investigate the TVET college lecturers' instructional practices in their classrooms. Four TVET colleges as well as eight lecturers were purposefully and conveniently selected for the study. The technological pedagogical content knowledge (TPACK) framework was used as an underpinning framework. Findings reveal that lecturers are not keen in integrating ICTs in their teaching and some are not encouraged to do so. It was also found that not all lecturers are adequately qualified to teach in the vocational field. The study recommends that teaching resources be sought in order for colleges to align their practices with industrial practices. Lecturers too should be capacitated in integrating technology in their lessons.

This study was conducted in response to the call made by the Department of Higher Education and Training (DHET) in South Africa to strengthen the awareness levels of TVET colleges' readiness to embrace the 4IR era. The purpose of this study was to focus on equipment alignment between TVET colleges and industries. This study used Eulau and Karps' theory of responsiveness as a guide to explore the purpose. Also, this study purposefully sampled five TVET colleges in Limpopo province and two civil engineering industries linked to these institutions. This study used a descriptive qualitative research design. Document analysis and non-participant observations were used as data collection instruments. The study found that the working tools and equipment used by these TVET colleges were not fancy or showing prospects of Fourth Industrial Revolution. This was the same thing with the linked industries. Hence, all tools used were simply outdated when it comes to 4IR integration. And so, the study recommends that TVET colleges should institute new partnerships with 4IR responsive industries than being linked to industries that are using conventional tools and equipment.

The Influence of COVID-19 Outbreak on the Readiness of Firms to Cyber Threats
Authors: Zwilling Moti
Published: December 2020

Technology impacted the lives of millions of people with their home day-to-day activities. When the COVID-19 pandemic struck in many countries, there was a need to change both the mode of working with technology as well as to handle internet and online risks exposure. During the pandemic, cybercrime groups utilized the internet usage to commit cybercrimes especially by exploiting vulnerabilities of many applications, networks, and infrastructures. This study aims to explore the impact of COVID-19 on the readiness of organizations to handle cyber threats in two directions: 1) analysis of CVE common vulnerability data before and during the pandemic period and 2) analysis of fuzzy logic data model designed to demonstrate the importance of firms readiness to cope with cyber threats. Results show that due to the significant increase in cyber threats, small firms tend to be more fragile to cyber threats than big ones, and they have to invest more resources to mitigate cyber threats. Findings and implications are discussed.
