Assessment of genetic diversity in Moroccan sesame (Sesamum indicum) using ISSR molecular markers
Authors: El Harfi Meriem , Charafi Jamal , Houmanat Karim , Hanine Hafida , Nabloussi Abdelghani
Published: January 2021

There is a need for sesame (Sesamum indicum L.) breeding in Morocco to release performant and adapted varieties, which requires a large genetic variability in the germplasm to be used. In this context, genetic diversity of sesame populations from different locations in Tadla area was investigated using ISSR (Inter Sequence Simple Repeats) markers as a simple method to reveal polymorphism among them. A total of 130 individuals representing 31 populations were sampled. Twenty-four ISSR primers were used for analysis of individuals representing the 31 different sesame populations grown in different agroclimatic zones of Tadla, accounting for 90% of sesame cultivation area in Morocco. Indeed, seven primers showed legible and reproducible genomic profiles with an interesting number of bands. A total of 57 bands were obtained with ISSR primers, of which 47 were polymorphic. PIC (Polymorphic Information Content) ranged from 0.002 to 0.350, showing that ISSR markers are informative and relevant for discriminating the populations evaluated. The similarity coefficient of ISSR data ranged from 0.509 to 1, with an average of 0.870. The results obtained showed that Moroccan sesame populations are characterized by a low genetic diversity, suggesting a genetic proximity among them. Therefore, new germplasm should be either introduced from diverse geographical origins or created through mutagenesis breeding in order to broaden the existing genetic variability.
Migratory routes, domesticated birds and cercarial dermatitis: the distribution of Trichobilharzia franki in Northern Iran
Authors: Ashrafi Keyhan , Sharifdini Meysam , Darjani Abbas , Brant Sara V.
Published: January 2021

Background: One of the major migration routes for birds going between Europe and Asia is the Black Sea-Mediterranean route that converges on the Volga Delta, continuing into the area of the Caspian Sea. Cercarial dermatitis is a disorder in humans caused by schistosome trematodes that use aquatic birds and snails as hosts and is prevalent in areas of aquaculture in Northern Iran. Before the disorder can be addressed, it is necessary to determine the etiological agents and their host species. This study aimed to document whether domestic mallards are reservoir hosts and if so, to characterize the species of schistosomes. Previous work has shown that domestic mallards are reservoir hosts for a nasal schistosome. Results: In 32 of 45 domestic mallards (Anas platyrhynchos domesticus) (71.1%), the schistosome Trichobilharzia franki, previously reported only from Europe, was found in visceral veins. Morphological and molecular phylogenetic analysis confirmed the species designation. These findings extend the range of T. franki from Europe to Eurasia. Conclusion: The occurrence of cercarial dermatitis in Iran is high in areas of aquaculture. Previous studies in the area have shown that domestic mallards are reservoir hosts of T. regenti, a nasal schistosome and T. franki, as shown in this study. The genetic results support the conclusion that populations of T. franki from Iran are not differentiated from populations in Europe. Therefore, the schistosomes are distributed with their migratory duck hosts, maintaining the gene flow across populations with compatible snail hosts in Iran.
Quality of Mobile Apps for Language Learning
Authors: Kruchinin Sergei , Bagrova Ekaterina
Published: January 2021

Mobile apps are new format of learning foreign languages. They are great as an additional way of learning, but cannot be a substitute for ordinary learning. Each app provides its own way of learning a foreign language. Each of them has its own pros and cons, and none of them is the best one. A combination of several apps is more efficient than using just one of them. However, all of them are dedicated to learning a language instead of practicing a language. Therefore, tutors, educational groups, and other regular forms of education cannot be fully substituted by mobile apps for language learning.

Published: January 2021

The article is devoted to an urgent problem related to the security of critical information infrastructure. The introduction of digital technologies in all spheres of society is in line with the priority policy for the development of the digital industry. At the same time, the number and quality of cyberattacks on significant objects of critical information infrastructure is constantly increasing in the world. But not all subjects of information relations, even understanding the presence of threats, are able to adequately assess and organize an effective security system for these objects. In this regard, ensuring the security of significant objects of critical information infrastructure is currently the primary task of the state - both the Russian Federation and other countries. The article provides a comparative analysis of approaches to ensuring the security of critical information infrastructure in Russia and in foreign countries. The problems of legal regulation of critical information infrastructure in Russia are identified and solutions are proposed to overcome them. There are traced the shortcomings associated with the implementation of legislation on the security of critical information infrastructure in Russia: in the digital industry, it becomes difficult to differentiate information infrastructure objects and classify some of them as critical; not all relevant legal entities have provided information on critical information infrastructure facilities, and therefore the register of facilities was not compiled in full, cyberattacks on which would create dangerous consequences for the country; some subjects of the critical information infrastructure deliberately underestimate the importance of their objects.

Authors: Gretchenko Anatoly , Gretchenko Alexander
Published: January 2021

Freelancing is largely based on finding a job through the Internet and by means of the Internet, which allows you to open up new opportunities for the Russian economy and make structural changes to it. But the attitude of Russian society to the new form of employment is still poorly understood. At the moment in Russia, freelancing is at the stage of development and its further development depends on the attitude of the society towards this type of employment. Today, Russian society is undergoing especially important changes in connection with the pandemic, which turned out to be an unexpected test for every person, as well as for the whole society. The self-isolation regime has strongly affected the economic spheres of life, confronted companies with remote work, and people with an understanding of all the positive and negative aspects of working outside the office. The hypotheses put forward have been partially confirmed. In modern Russian society, the attitude towards the freelancers is rather neutral, but the share of positive assessments is also high. A small proportion of respondents expressed a negative attitude towards the freelancers, which indicates an overall good attitude towards freelancing. Therefore, the main goal of this article is to identify the attitude towards freelancing in modern Russian society.

Published: January 2021

The actual methods of labor market analysis are based on outdated technologies for collecting information and do not consider the competencies available in the CV and in demand by vacancies. In order to obtain reliable current information on the balance of the workforce quality, as the carrier of certain competencies, and market requirements, the method is proposed for determining the degree of their consistency through the ratio of competencies available to applicants and those requested by employers. The proposed methodology, based on big data technologies, uses artificial intelligence as the main toolkit which makes it possible to quickly and efficiently collect, process and visualize the obtained data, which makes it possible to conduct its further qualitative analysis in the context of the proposed / demanded competencies, professions, regions and types of economic activities. As a practical interpretation of the proposed methodology, the paper analyzes the degree of consistency of existing / demanded competencies in the context of the regions of Belarus.

A Novel Text Analysis Method: Numerals Reveal the Author
Authors: Zenkov Andrei , Zenkov Eugene , Belke Ansgar
Published: January 2021

Two approaches to the statistical analysis of texts are suggested, both based on the study of numerals occurring in literary texts. The first approach is related to the study of the frequency distribution of various leading digits of numerals occurring in the text. This approach is convenient for testing whether a group of texts has common authorship: the latter is dubious if the frequency distributions are sufficiently different. The second approach requires the study of the frequencies of numerals themselves. The approach yields information about the author, stylistic and genre peculiarities of the texts and is suited for advanced study of authorial texts. The hypothesis that I. Ilf and E. Petrov are fake authors of novels "The Twelve Chairs" and "The Little Golden Calf", and they were ghosted by M. Bulgakov, is checked. The frequency distribution of numerals, as well as its cluster analysis, do not confirm this hypothesis.

Authors: Utkina Aleksandra , Karagodin Vasiliy
Published: January 2021

The possibilities of nutrigenomics as an approach to determining the effectiveness of specialized food products have been studied. For this purpose, the influence of consumption of whey protein concentrate FitPROTEIN and the carrier of branched-chain amino acids SPORTAMIN®BCAA 6000 on the expression of the target gene FTO was determined. Despite a certain similarity in the composition of these products, their effect on the average level of FTO gene expression is significantly different. The results obtained are discussed from the standpoint of identification of the target gene, detection of gene polymorphism, analysis of expression data and the possibility of updating these procedures using digital technologies. An algorithm for evaluating the effectiveness of specialized food products based on nutrigenomic studies is proposed. Nevertheless, it seems promising to transfer experimentation to the virtual sphere through the use of digital twins, including in combination with the Internet of Things.

The implementation of a century foreign experience of affordable housing in construction management - a new format of economy in Russia
Authors: Leonova Leyla , Fedorov Anatoly , Czerny Tomash
Published: January 2021

The article is devoted to the formation and history of the creation of a unique organizational model for managing the construction of affordable (social) housing on the example of the capital of Austria. The relevance of the functioning of such a model is indisputable, since at present, multiscale migration processes are taking place in large cities not only in the EU countries, but also in Russia. Moreover, migration takes place mainly from third world countries. In such conditions, there is an acute issue of providing the population with affordable, comfortable housing, without disturbing historical and architectural monuments. This model was formed and has been successfully operating in Vienna for over 100 years. Its uniqueness lies in the fact that the main role in it is played by the municipal authorities. Exactly they create social programs in the field of housing construction and funding them. At the same time, the rental housing market is becoming more comfortable and of high quality. The principles of social justice in the housing market for socially disadvantaged groups of the population are observed.

This model of the functioning and formation of the affordable housing market in Vienna, according to the authors of the article, personifies the formation and functioning of the socio-economic cluster in the housing and communal sector. Of course, such a positive experience of providing the country's citizens with affordable and comfortable apartments is possible and necessary to apply in Russia.

Indices of socio-economic development in the space of characteristics of regional differentiation
Authors: Afanasiev Mikhail Y. , Kudrov Aleksander V. , Lysenkova Maria А.
Published: January 2021

As a rule, the source information and methods used for construction of many indices have specifics that allow authors and experts to consider these indexes as original and recommend them for use in solving a number of management tasks. However, a comparative analysis of such indices sometimes shows that despite the peculiar names and methods of calculation, some of them do not have significant statistical differences. This paper presents an approach that allows us to compare an arbitrary set of indices and ratings that characterize the level of socio-economic development of the subjects of the Russian Federation in the space of characteristics of differentiation used in solving regional management problems. The purpose of the study is to identify indexes that do not differ significantly. Eighteen indexes are compared. At the first stage of the study, their correlation analysis is performed. Then the indices are regressed to the basic characteristics of differentiation. The analysis of cosines of angles between indices calculated using beta coefficients of regressions allows us to refine the results of correlation analysis and identify a subset of indices that are not distinguishable in solving regional management problems.

Fraud transactions revealing as phase of financial analysis in Forensic Economic Examination
Authors: Astrakhantseva Irina , Astrakhantsev Roman
Published: January 2021

The scientific research study is about financial methodology analysis improving in the framework of forensic economic examination. The objective bankruptcy date is one of the issues within the forensic examination. The authors propose to supplement the classical financial analysis with a special section, which analyzes transactions for compliance with market conditions, identifies schematic and fictitious transactions, and also determines the degree of their impact on the occurrence of property insufficiency and signs of bankruptcy. The author's classification of possible schematic transactions, as well as methods for establishing the fact of compliance with the market situation are proposed. As the criterion for the maximum permissible deviations of transaction values from market values, it is proposed to use a value in an amount not exceeding the change in values by more than two times. The technical assets identified as a result of fictitious transactions are proposed to be deducted from the market value of assets when calculating the net assets of the organization, which will allow the most correct determination of the objective bankruptcy date.
Essential characteristics of ethnopolitical communications
Authors: Suleymanova Shukran , Dzhanteeva Julieta
Published: January 2021

The article considers the communicative essence of ethnopolitics and ethnicity. Methodological approach: communication in its political meaning is analyzed as a social phenomenon, covering all aspects of subjective perception, interpretation and assimilation of information by people, all aspects of the process of establishing meaningful contacts between senders and recipients of political information and its application following the intentions of subjects. The authors define communications in the sphere of politics or political communications as meaningful and targeted actions. Results: the norms and values of particular social groups may not coincide with each other, and in this case, it is difficult to speak about the normative-value system of society. However, this allows structuring political communications by distinguishing norms, values and the corresponding political action of individuals, belonging to specific social groups-ethnic, cultural and diaspora. In this case, political communications are a set of culturally determined interactions, which characterize the presence of significant and insignificant differences in the communicating parties in relation to the power, government, party system, and methods of political participation.

The bikini incision anterior cemented total hip arthroplasty: Assessment of radiological and clinical outcomes
Authors: Nizam Ikram , Alva Avinash , Gogos Sophia
Published: January 2021

Introduction: There has been an increased interest in minimally invasive direct anterior approach total hip arthroplasty (THA) to provide greater patient satisfaction, improve pain relief, and reduce the duration of hospitalisation. A direct anterior approach hybrid cemented THA, utilising a bikini line incision, can be technically challenging. We aimed to undertake radiological analysis of femoral stem cementation, clinical outcomes, and component survivorship. Methods: Over a 5-year period, 215 primary elective bikini anterior THA conducted by a single surgeon were included. All procedures were performed using a cemented collarless polished stem. The operation was performed on a standard operating table. Patients undergoing posterior approach, revision procedures, and fractured neck of femurs were excluded. Post-operative radiographs were analysed for femoral cementation quality using the Barrack grading system. Harris hip scores (HHS) were determined at 6 weeks, 12 weeks, annually thereafter and the difference in HHS was noted. Results: In total, 215 anterior bikini THA (R = 101, L = 114) were performed in 199 patients (M = 89, F = 110) with a mean age of 77 and mean follow up of 2.9 years (range = 0.5–5). Radiographic analysis of femoral cementation showed 189 femoral stems (88%) were either Barrack A or B cementation grade, suggesting optimal cementation. Lucency in the cement-bone interface occurred mainly in Gruen Zone 1 (43%) and Zone 13(46.9%). At the most recent follow-up (mean 2.9 years), component survivorship was at 99.54% (stem). Significant improvement was noted in Harris hip scores at final follow-up (from 54 preoperatively to 92.7 at 2.9 years postoperatively). Conclusion: Our results suggest that a bikini incision direct anterior approach for total hip arthroplasty can be safely employed to perform cemented femoral stems on a standard operating table.

Published: January 2021

The Constellation Observing System for Meteorology, Ionosphere, and Climate 2 (COSMIC-2) mission was launched into a low-inclination (24°) orbit on June 25, 2019. Six satellites, each with an advanced Tri-GNSS Radio-Occultation Receiver System (TGRS), provide a global and uniform data coverage of the equatorial region with several thousand electron density profiles daily. The COSMIC-2 electron density profiles, and specifically the derived ionospheric F2 peak parameters, are properly validated in this study with reliable “truth” observations. For this purpose, we used manually scaled ionograms from 29 ground-based ionosondes located globally at low and middle latitudes. For this validation campaign, we considered only geomagnetically quiet conditions in order to establish benchmark level of the new mission’s ionospheric observation quality and to evaluate the operational capability of the COSMIC-2 Radio Occultation (RO) payload at the background of normal day-to-day variability of the ionosphere. For reliable colocations between two independent techniques, we selected only COSMIC-2 RO profiles whose F2 peak point coordinates were within 5° of the closest ionosonde. Our comparison of the ionospheric F2 peak height (hmF2) derived from COSMIC-2 RO and ground-based ionosonde measurements showed a very good agreement, with a mean of ~5 and ~2 km at low and middle latitudes, respectively, while RMS error was of ~23 and ~14 km, respectively. That range corresponds to a deviation of only 6–9% from the reference, ionosonde observations. Examination of representative collocation events with multiple (2–5) simultaneous RO tracks near the same ionosonde with different RO geometry, multi-satellite and multi-GNSS combination give us observational evidence that COSMIC-2 RO-based EDPs derived from GPS and GLONAS links show good self-consistency in terms of the ionospheric F2 peak values and electron density profile shape. We can conclude that COSMIC-2 provides high quality data for specification the ionospheric electron density at the F2 peak region.

Background Robotic liver surgery is emerging as the future of minimal invasive surgery. The robotic surgical system offers a stable camera platform, elimination of physiologic tremor, augmented surgical dexterity as well as improved ergonomics because of a seated operating position. Due to the theoretical advantages of the robotic assisted system, complex liver surgery might be an especially interesting indication for a robotic approach since it demands delicate tissue dissection, precise intracorporeal suturing as well as difficult parenchymal transection with subsequent need for meticulous hemostasis and biliostasis.

Material and methods An analysis of English and German literature on open, laparoscopic and robotic liver surgery was performed and this review provides a general overview of the existing literature along with current standards and aims to specifically point out future directions of robotic liver surgery.

Results Robotic liver surgery is safe and feasible compared to open and laparoscopic surgery, with improved short-term postoperative outcomes and at least non-inferior oncological outcomes.

Conclusion In complex cases including major hepatectomies, extended hepatectomies with biliary reconstruction and difficult segmentectomies of the posterior-superior segments, robotic surgery appears to emerge as a reasonable alternative to open surgery rather than being an alternative to laparoscopic procedures.

Introduction In the management of patients with decompensated liver cirrhosis, transjugular intrahepatic portosystemic shunt (TIPS) insertion is well-established but common recommendations in the follow up management are inconsistent. Doppler sonography is commonly used for detection for TIPS dysfunction whilst data on the impact of elective invasive examinations are scarce.

Aim The aim of this retrospective analysis is to evaluate potential benefits of elective invasive examinations in the follow up management of patients after TIPS insertion

Methods Data of all patients receiving TIPS at the university hospitals of Muenster and Bonn between 2013 and 2018 (n = 534) were collected. The impact of performance of elective invasive examinations at 12 months after TIPS insertion on the occurrence of liver related events (LREs) and frequency of TIPS revisions within 24 months after TIPS insertion was analyzed.

Results No significant differences were found concerning occurrence of liver related events after 24 months depending on whether an elective invasive examination was performed. Occurrence of hepatic encephalopathy, relapse of initial indication for TIPS, as well as death or liver transplantation all did not differ. These findings were verified by a subgroup analysis including only patients who did not experience a LRE or TIPS revision within the first 12 months after TIPS procedure.

Conclusion The analyzed data suggest no evidence for a beneficial impact due to implementation of an elective invasive examination program after TIPS insertion. Invasive examinations should remain reserved to patients with suspected TIPS dysfunction.

Background Esophagogastroduodenoscopy (EGD) is a prerequisite for detecting upper gastrointestinal lesions especially early gastric cancer (EGC). An artificial intelligence system has been shown to monitor blind spots during EGD. In this study, we updated the system (ENDOANGEL), verified its effectiveness in improving endoscopy quality, and pretested its performance in detecting EGC in a multicenter randomized controlled trial.

Methods ENDOANGEL was developed using deep convolutional neural networks and deep reinforcement learning. Patients undergoing EGD in five hospitals were randomly assigned to the ENDOANGEL-assisted group or to a control group without use of ENDOANGEL. The primary outcome was the number of blind spots. Secondary outcomes included performance of ENDOANGEL in predicting EGC in a clinical setting.

Results 1050 patients were randomized, and 498 and 504 patients in the ENDOANGEL and control groups, respectively, were analyzed. Compared with the control group, the ENDOANGEL group had fewer blind spots (mean 5.38 [standard deviation (SD) 4.32] vs. 9.82 [SD 4.98]; P < 0.001) and longer inspection time (5.40 [SD 3.82] vs. 4.38 [SD 3.91] minutes; P < 0.001). In the ENDOANGEL group, 196 gastric lesions with pathological results were identified. ENDOANGEL correctly predicted all three EGCs (one mucosal carcinoma and two high grade neoplasias) and two advanced gastric cancers, with a per-lesion accuracy of 84.7 %, sensitivity of 100 %, and specificity of 84.3 % for detecting gastric cancer.

Conclusions In this multicenter study, ENDOANGEL was an effective and robust system to improve the quality of EGD and has the potential to detect EGC in real time.
