Published: December 2020

AbstractOne of the significant consequences of alcohol consumption is cancer formation via several contributing factors such as action of alcohol metabolites, vitamin deficiencies, and oxidative stress. All these factors have been shown to cause epigenetic modifications via DNA hypomethylation, thus forming a basis for cancer development. Several published reviews and studies were systematically reviewed. Omnivores and vegetarians differ in terms of nutritional intake and deficiencies. As folate deficiency was found to be common among the omnivores, chronic alcoholism could possibly cause damage and eventually cancer in an omnivorous individual via DNA hypomethylation due to folate deficiency. Furthermore, as niacin was found to be deficient among vegetarians, damage in vegetarian chronic alcoholics could be due to increased NADH/NAD+ ratio, thus slowing alcohol metabolism in liver leading to increased alcohol and acetaldehyde which inhibit methyltransferase enzymes, eventually leading to DNA hypomethylation. Hence correcting the concerned deficiency and supplementation with S-adenosyl methionine could prove to be protective in chronic alcohol use.
A Comparative Study of Various Artificial Intelligence Based Agents for the Game of Angry Birds With and Without Splitting
Authors: Kumar Ankit , Jani Kunal , Sahu Nabin Kumar 
Published: December 2020

Abstract
In a game of angry birds, birds are fired from a slingshot and are targeted towards stationary pigs located at different fixed distances from the slingshot. The angry birds have to be fired in such a way that it lands as close as possible to the pigs’ location. The goal is to develop an artificial intelligence-based model that would play the angry birds game based on the past human experience. In this game, the user will give the initial velocity and the angle of projection. Based on these parameters, the shot will be played, and the outcome is stored as a tuple consisting of the initial velocity, the angle of projection, and the location of pigs that have not been destroyed in a database. The machine learning-based agent reads the data from the database, trains itself based on the outcome of previous shots stored in the database, and plays the best possible shot according to the data retrieved from the database. Two machine learning models have been proposed, which are the K Nearest Neighbours model and the Naive Bayes model. The third model is the stochastic gradient descent model, which plays a shot based on the minimization of the distance between the angry bird and the pig using an objective function in terms of the initial velocity and splitting angle. The performance of both these agents has been compared with the human agent’s performance in terms of the average number of wins per 100 games.

The composition of the software for implementing the proposed method is shown.
Evaluation issues of query result ranking for semantic search
Authors: Kanev A I , Terekhov V I 
Published: December 2020

Abstract
Application of semantic in information retrieval is a dynamically developing area. Nowadays, elements of semantic search are used in popular systems such as Microsoft Azure, Abbyy Intelligent Search, Google Search with BERT. Using sematic search, it is possible to obtain documents that contain exact meaning instead of set of words. But Lucene is still one of the most popular libraries for search purpose and it has its own syntax for fuzzy, wildcard, proximity and other modifiers for queries. To evaluate precision and recall of search the authors have created a list of queries and divided it into groups according to a query type. The article contains results of this investigation for semantic search with metagraph knowledge base in comparison to Lucene with the same morphological analyzer. The quantity of documents for two types of search may be the same but ranking should be different. Ranking of queries is another issue and its evaluation is not a trivial task. In this article the authors applied Levenstein distance but then proposed a new method for comparison of ranking given by different search engines. All results were obtained on Open Corpora text corpus.
Implementation of a Policer-Based Control Loop For The Dynamic Resource Allocation of a Software-Defined Communication Infrastructure

Published: December 2020

Abstract
The use of solutions based on the principles of virtualization is designed to increase the efficiency of using the communication infrastructure due to the dynamic distribution of existing communication and computing resources between their virtual components. The software management of the communication infrastructure components opens up opportunities for applying new approaches to solving the currently very urgent problem of ensuring the required Quality of Service. Taking into account the current trends in the development of communication infrastructures and means of their automation, it seems relevant to build systems that implement a closed cycle of communication infrastructure resource management based on traditional and promising tools for monitoring and managing QoS and studying its behavior. Closing the control loop is achieved by implementing a control script that automatically responds to changes in the transmitted data and makes decisions about changing the current configuration of network devices. One of the approaches to building a closed control loop is to change the physical bandwidth of a virtual communication channel depending on the intensity of its resource use. The paper considers an example of the implementation of a closed control loop based on the rules of the policy for limiting the rate of sending packets of heterogeneous traffic and compares the approach of dynamic bandwidth redistribution with traditional approaches.
Pattern Matching-based scraping of news websites
Authors: Salem Hamza , Mazzara Manuel 
Published: December 2020

Abstract
Web Scraping is the process of extracting content from human-readable websites in order to import it into local storage such as databases or CSV Files. The process of data extraction and its design is time-consuming requiring an analysis of the website, data representation of the objects comprising its structure (DOM), HTML tags, and the Cascading Style Sheets (CSS) classes. To support this process we aim at providing automation. In this paper, we propose a pattern mining technique to scrap news and blog websites by recognizing title and body based on a content structure pattern. This approach consists of three steps, i.e.: extracting news website structure, constructing a pattern of HTML content, and implementing the pattern as a set of rules in web scraping. Our approach is a simple, general, and straightforward way to extract articles that consist of the title, the body of any blogs, or news websites.

Published: December 2020

Abstract
It is known that modeling consists of a few stages. Analytic calculations are made first and afterwards, they are converted into numerical ones. It is a fairly complicated task, but it can easily be solved with the help of programming languages with the support of a numerical–analytical approach. In this case, the program can generate a numerical scheme for the solution based on the given analytical equation. The possibility of high-level work and differential equations’ modeling is obtained through the access to the additional packages. This article overviews one of the approaches, specifically the usage of the different integrated DSL packages in Julia language.

Authors: Eremenko M M , Solodovnik M S , Balakirev S V , Chernenko N E , Kots I N , Ageev O A 
Published: December 2020

Abstract
In this work, the effect of the dose of implantation of Ga atoms into the silicon surface on the epitaxial growth of GaAs was investigated. We demonstrate that the deposition of GaAs occurs mainly on modified areas. Separate crystallites of GaAs with an irregular shape are formed on modified areas at the lowest dose of Ga implantation equal to 1 pC/μm2, whereas an increase in the dose of Ga implantation leads to the coalescence of GaAs areas. At a maximum dose of 21 pC/μm2, degradation of the morphology and a decrease in the degree of filling of the area are observed, which is also confirmed by an increase in the roughness of the structure.

Published: December 2020

Abstract
Misfit strains and stresses of a dilatation line in an elastic body with an angular free surface are studied with potential application to semiconductor nanoheterotechnology. The misfit stress fields in a wedge-shaped isotropic elastic space containing a dilatation line are calculated using the method of virtual surface dislocations and a Mellin transformation. Analysis of this solution is carried out numerically by using the misfit stress maps built in a cross section of the system.
Kinetic Monte Carlo simulation of the growth of In nanostructures by droplet epitaxy on AlGaAs nanopatterned surfaces
Authors: Balakirev S V , Solodovnik M S , Eremenko M M , Chernenko N E , Ageev O A 
Published: December 2020

Abstract
In this paper, the results of the simulation of the In/AlGaAs growth on nanopatterned surfaces using modified analytical–Monte Carlo model are presented. The surface density of nanostructures is demonstrated to slightly decrease with increasing Al content. A decrease of an interhole distance leads to the occupation of a small part of a hole which can be prevented by a decrease of the hole volume. The best localization of In nanostructures on AlGaAs surfaces nanopatterned with holes at a distance of more than 125 nm can be achieved at a temperature of 300°C or higher. A decrease in temperature requires a sufficient decrease of an interhole distance to avoid nucleation beyond predefined positions.

Published: December 2020

Abstract
Epitaxial GaN layers were synthesised by PA MBE on Si (111) with and without using the high-temperature nitridation. We performed a complete investigation of their structural and optical properties. It was proven that the presence of GaN epitaxial layer less than a micrometer leads to the appearance of tensile stress in the structure. The stress was calculated and compared for the structure with nitridation and without it. The effect of nitridation on holes density was also observed by Raman spectroscopy and Hall measurements.

Published: December 2020

Abstract
Artificial cell fusion is a widely used approach in cell biology and biomedicine. Femtosecond laser-induced cell fusion is considered to be a precise and low-invasive tool for the cell fusion. However, the percentage of somatic cell fusion remains not very high, and the use of polyethylene glycol is often required. In our research we propose the use of rotating optical chopper to produce ultra-short trains of femtosecond pulses (up to 1 ms) for decreasing the laser impact. It helps to control the appearance and size of gas-vapor bubbles, avoiding cell destruction. We achieved the cell fusion efficiency of 45% without the use of polyethylene glycol, but only in freshly thawed cells. Continuously cultured cells completely failed to fuse.

Authors: Toikka A S , Kamanina N V 
Published: December 2020

Abstract
Due to their unique properties and scalable technology, optical devices based on the liquid crystals are widely used in industry. In optoelectronics, an LC is used to design the optical limiters, switches, and spatial light modulators. Response time, electrical consumption and optical transmittance are the most important parameters of an electro-optical modulator. Temporal parameters substantially depend on the level of the applied supply voltage and on the number of layers used in the structure of the LC device. In this paper, it is proposed to compare the reflection losses level of samples with pure ITO and samples with ITO conducting coating modified by carbon nanotubes (CNTs).

Published: December 2020

Abstract
The IV characteristics of previously found structure fragment with not optimized isotype hetero-barriers in the bottom connecting part of triple-junction GaInP/GaAs/Ge solar cell has been investigated. It has been shown that there are various ways to obtain the IV-curves of such fragment, including by creating structures containing only an isotype substrate and layers forming the barriers. It has been found that if hetero-barrier fragment contacts with the p-n junction layers, the shape of its reverse IV characteristic dramatically changes and depends on the incident light intensity.

Published: December 2020

Abstract
The experimental characteristics of GaAs p-i-n structures with InGaAs quantum objects (QOs) have been investigated. The study of electroluminescence spectra has shown that an increase of the number of QOs layers leads to relative increase in electroluminescence intensity from QOs and decrease it from the GaAs matrix. The observed increase in QOs recombination has resulted in a drop of open circuit voltage. It has been shown that recombination through deep levels in the QOs begins to dominate over recombination in the matrix at lower number of QOs layers than that through band-to-band recombination.
