Authors: Megha Swati , Salem Hamza , Ayan Enes , Mazzara Manuel 
Published: December 2020

Abstract
Since the beginning of the 2010s major car manufacturers progressively started to invest in Autonomous Vehicles(AV). Notable examples are Tesla, Ford, and Toyota. Small startups and tech giants like Google and Yandex are now also entering the competition to propose new solutions. Most of them have already developed their prototypes of driverless vehicles that you can normally observe in the streets of New-York, USA, or Innopolis, Russia. Despite the significant hype on this technology, current solutions are not always optimal and multiple challenges are left open in a domain such as security, data integrity, privacy, and communication. Blockchain is one of the most appealing technologies to be used in this domain since it provides solutions for some of these challenges. In this paper, we describe, categorize, and evaluate different solutions of the Autonomous Vehicles Industry that makes use of Blockchain. We use a software engineering approach to organize the existing work in multiple categories such as challenges addressed, quality attributes promoted. This work is intended to provide researchers in the field with a well-defined and structured categorization, plus insights into the existing literature.

Application of Data-Oriented Design in Game Development
Authors: Fedoseev K , Askarbekuly N , Uzbekova A E , Mazzara M 
Published: December 2020

Abstract
Game development is a big, human resource intensive industry. Object-Orientated Design (OOD) is the most popular software design paradigm in game development. However, it is not the optimal choice whet it comes to performance and resource utilization. To solve this problem, Data-Oriented Design (DOD) can serve as an alternative for resource-intensive games where performance is the highest priority. The latter approach is often perceived as something exclusive to highly qualified specialists. Thus, a question arises whether DOD can suit and be useful for smaller companies and projects, and what are the trade-offs of using the approach compared to more wide-spread object-orientation.
This paper examines the experience of a small game development team implementing two similar case study projects, one using OOD and another using DOD. After an overview of both implementations, the authors analyze and compare the two projects in regards to performance and maintainability. Recommendations are given on when each of the two design approaches should be applied and what are the corresponding skill sets for developers to use them.
Optical transparency and conductivity of oriented platinum nanonetworks on a glass surface
Authors: Nizameeva G R , Nizameev I R , Nefedev E S , Kadirov M K 
Published: December 2020

Abstract
The work is aimed at creating an optically transparent conductive coating based on platinum nanowires which can become an alternative to the existing indium tin oxide. This coating can be used as transparent electrodes in solar panels, organic LEDs and many areas of modern electronics and optoelectronics. In work, the dependence of the sheet resistance of oriented platinum nanowires network on the amount of metal used is investigated. Oriented platinum nanowires are obtained by chemical deposition from an aqueous solution of hexachloroplatinic acid on a glass surface. The topography of the deposited metal layer on the glass is visualized by atomic force microscopy. It has been established that the platinum layer has good optical transparency. The synthesized coating would be of interest in terms of applicability as an optically transparent electrode.

Authors: Permyakova O O , Miakonkikh A V , Rudenko K V , Rogozhin A E 
Published: December 2020

Abstract
The effect of ion implantation on the characteristics of resistive switching in the structure of Ni/Pt/HfO2/TaN/TiN with an oxide layer thickness of 10 nm is considered. It was shown that after implantation of Ne+ ions, the forming voltage decreases by 0.5 V, while after implantation of Ar+ ions, the share of the forming-free cells increased from 0.1 to 0.6. Resistive switching after implantation of Kr+ ions is entirely absent.
Effect of the Al content in the substrate on the In nanodroplets growth by droplet epitaxy
Authors: Chernenko N E , Balakirev S V , Eremenko M M , Solodovnik M S 
Published: December 2020

Abstract
The paper presents the results of an experimental study of the effect of Al content in the epitaxial surface layer on the growth of In nanostructures formed by droplet epitaxy. We have shown that an increase in the Al content leads to a decrease in the droplet density and an increase in their size. We also showed that the influence of the Al content on the droplet characteristics is much less significant than that in case of the Stranski-Krastanov growth. The increase in the critical thickness of droplet formation on Al-containing surfaces when the temperature decreases is not significant. It allows us to control quantum dot emission wavelength almost independently of their geometric characteristics.

Authors: Volkova M G , Storozhenko V Yu , Petrov V V , Bayan E M 
Published: December 2020

Abstract
To obtain high-quality nanocrystalline transparent ZnO films, a new pyrolysis synthesis method was used. The resulting material was investigated by x-ray diffraction, scanning electron microscopy. Structural analysis of the films shows that they are polycrystalline and have a wurtzite structure. The film structure consists of nanocrystallites about 10–20 nm in size, uniformly distributed over the surface of the substrate and over the thickness of the film. The temperature dependence of the resistance of the obtained films was also investigated. The activation energies of conductivity are determined by the donor conductivity levels existing in zinc oxide, and temperature hysteresis is determined by the effect of charging oxygen adsorbed on the surface of zinc oxide.

Authors: Nikolskaya A A , Korolev D S , Konakov A A , Mikhaylov A N , Belov A I , Marychev M O , Murtazin R I , Pavlov D A , Tetelbaum D I 
Published: December 2020

Abstract
To study the mechanism of a 9R-Si hexagonal phase formation upon ion irradiation of the SiO2/Si system, three types of experimental samples have been investigated by photoluminescence (PL) spectroscopy and transmission electron microscopy (TEM): SiO2/Si system irradiated by Kr+, silicon irradiated by Kr+ and silicon irradiated by (Kr+ + O+) ions. All the samples were annealed after irradiation. The first type sample shows the presence of the 9R-Si phase and PL band at ∼ 1240 nm; the third type sample shows the same PL band and twin defects; for the second type sample, the PL at 1240 nm is not detected. Based on the results, the role of mechanical stresses, radiation defects and oxygen in the formation of the hexagonal silicon phase is discussed.

Published: December 2020

Abstract
Transparent zinc oxide ceramics, undoped and doped with 0.1-2.0 wt% Er3+ ions were fabricated by uniaxial hot pressing of commercial oxide powders. The ceramics were characterized by X-ray diffraction, SEM, EDX, Raman, X-ray and optical spectroscopy. The analysis of morphology of Er3+:ZnO ceramics reveals that the main components of texture are hexagonal prism planes similar to those for undoped ceramic. The ZnO grain size decreases with addition of Er2O3. The Er3+ ions are distributed between the ZnO grains and the Er2O3 crystals and do not enter the zinc oxide structure. The luminescence spectra of Er3+:ZnO ceramics contain emission bands originating from the intra-4f shell transitions of Er3+ ions and bands assigned to defect states at ZnO. The X-ray luminescence spectra indicate the possible energy-transfer between the ZnO grains and Er3+ ions. The defect luminescence band becomes weaker and the X-ray luminescence decay time decreases as the erbium concentration is increased.

Characterization of an RNase III mutant of Rhodobacter sphaeroides
Authors: Boerner J M 
Published: December 2020

Abstract
In this work an RNase III deletion mutant of the facultative phototrophic α-proteobacterium Rhodobacter sphaeroides was characterized. The aim of this study was to identify differences in phenotype and RNA physiology between wild type and mutant, which can be explained by a loss of RNase III activity. We analyzed the growth behaviour of the mutant and the wild type under different growth conditions, including microaerobic and phototrophic mode of growth. As Rhodobacter sphaeroides is known for its metabolic versatility, we were also interested in regulation of the transcriptome. The results suggests that the deletion of the RNase III coding gene (rnc) strongly impacts phenotype and transcriptome of Rhodobacter sphaeroides.
Revealing a possible sensor mechanism of DNA - based silver nanoclusters
Authors: Kapitonova M A , Reveguk Z V , Kononov A I 
Published: December 2020

Abstract
The mechanisms underlying the sensory activity of silver clusters (Ag NCs) synthesized on oligonucleotide matrices are not understood yet. It is known that close proximity of cytosine and guanine rich sequences causes colour changes in the luminescence of Ag NCs. We studied two types of fluorescence activation of Ag NCs due to close proximity of two DNA strands. We concluded that the activation phenomenon could be explained by the same mechanism, namely by the reassembling of the silver atoms on the double-stranded DNA formed upon hybridization. Our results could be useful for further Ag NCs-based sensors development.

Abstract
A method has been developed using wavelet transform to describe the dynamics of the pulse wave shape during the diagnosis of human health. The pulse wave signal, in contrast to the previously discussed diagnostics, is considered an unsteady signal, in which there may be no periodicity. We found that this method is useful for diagnosing the properties of arterial vessels of patients with coronary heart disease, arterial hypertension and other diseases. Pulse wave research results are presented.

Abstract
An automated complex for the study of the oxygen status of human body tissues using an artificial trained analytical system is presented. It includes sensory, electronic and computer modules for measuring and analyzing data. System training is implemented according to the principle of dividing the subjects into groups using mathematical methods of data processing and comparing them with data on the degree of adaptive responses obtained in the course of independent biomedical research. After analytical system training, subsequent recognition of the “image” of the test subject and its assignment to one or another group of the type of reaction to the functional load was possible.

Published: December 2020

Abstract
In this paper, we study the effect of the height and diameter of vertically aligned silicon structures on their optical properties. Structures with different geometry were formed using nanosphere lithography and dry etching. Nanosphere lithography was realized with 0.9 and 2 μm latex spheres. The etching process was carried out through a formed mask (template) composed of 0.9 and 2 μm latex spheres, respectively. The diameter of the spheres and the etching time determined the size of the formed structures and their optical properties. A significant reduction of the total reflection with height as well as blue shift of the minimum with diameter decrease were observed.

Authors: Romashkin A V , Polikarpov Yu A , Alexandrov E V , Nevolin V K 
Published: December 2020

Abstract
The spray-coating technique to form top transparent conductive and buffer uniform layers of carbon nanotubes (CNTs) and tungsten oxide nanoparticles (nWO3) from the solvents mixture on MEH-PPV layer, providing minimal underlying layer dissolution and acceptable interface quality, was proposed and can be used for solar cells (SC). The effect of neighboring layers mixing on the electrical characteristics of organic SC and methods for minimizing this mixing by optimizing solution composition, which was selected based on the MEH-PPV solubility and the stability of CNT dispersion, were studied. The dipping degree of CNTs and nWO3 in MEH-PPV and the interface quality was studied by measuring the CNT layer surface resistance and the nWO3 diameter on the surface, as well as analyzing the CVC hysteresis, photoresponse, and current drop time with forward bias after light off.

Authors: Kiseleva E S , Isaeva O L , Boronenko M B , Zelensky V I 
Published: December 2020

Abstract
In this paper, the movement of the pupils is a biometric indicator that analyzes the emotional state of a person. Eyetracking using infrared illumination based on the determination of the displacement vector between the centers of the pupil and the shine of the cornea gives results with high accuracy, provided that the human head is fixed. A method for determining the coordinates of the center of attention in the absence of fixation of the head without using infrared illumination is proposed. The accuracy of determining the coordinates of the center of attention is improved by moving from a coordinate system associated with a fixed head to a coordinate system associated with a moving center of the pupil.
Physico-mechanical properties and SEM of sol–gel plates based on chitosan L-(D-)ascorbate
Authors: Zhuravleva Yu Yu , Malinkina O N , Zudina I V , Shipovskaya A B 
Published: December 2020

Abstract
In our previous studies, it was shown that the isomeric form of ascorbic acid (L-or D-AscA) used to obtain the salt form of chitosan had a significant effect on the total space charge, size and general chirality of chitosan ascorbate macromolecules in solution, their stereomeric ordering in lyophilically isolated solid phase, as well as the kinetics of sol–gel synthesis of materials based thereon. This study examines the effect of L- and D-AscA on the physico-mechanical and morphological properties of thin-film sol–gel plates based on chitosan L-or D-ascorbate without and with Aloe Vera juice added. It has been established that the AscA isoform has a significant effect on the elastoplastic characteristics of the samples and the surface relief of their solid phase. The addition of Aloe Vera also leads to significant texturing of the surface relief. The latter could be used to design specific optical sensors and optodes of medico-biological purposes.
