Authors: Škola Filip , Rizvić Selma , Cozza Marco , Barbieri Loris , Bruno Fabio , Skarlatos Dimitrios , Liarokapis Fotis
Published: October 2020

This paper presents a combined subjective and objective evaluation of an application mixing interactive virtual reality (VR) experience with 360° storytelling. The hypothesis that the modern immersive archaeological VR application presenting cultural heritage from a submerged site would sustain high levels of presence, immersion, and general engagement was leveraged in the investigation of the user experience with both the subjective (questionnaires) and the objective (neurophysiological recording of the brain signals using electroencephalography (EEG)) evaluation methods. Participants rated the VR experience positively in the questionnaire scales for presence, immersion, and subjective judgement. High positive rating concerned also the psychological states linked to the experience (engagement, emotions, and the state of flow), and the experience was mostly free from difficulties linked to the accustomization to the VR technology (technology adoption to the head-mounted display and controllers, VR sickness). EEG results are in line with past studies examining brain responses to virtual experiences, while new results in the beta band suggest that EEG is a viable tool for future studies of presence and immersion in VR.
Seeing Pedestrian in the Dark via Multi-Task Feature Fusing-Sharing Learning for Imaging Sensors
Authors: Wang Yuanzhi , Lu Tao , Zhang Tao , Wu Yuntao
Published: October 2020

Pedestrian detection is an essential problem of computer vision, which has achieved tremendous success under controllable conditions using visible light imaging sensors in recent years. However, most of them do not consider low-light environments which are very common in real-world applications. In this paper, we propose a novel pedestrian detection algorithm using multi-task learning to address this challenge in low-light environments. Specifically, the proposed multi-task learning method is different from the most commonly used multi-task learning method—the parameter sharing mechanism—in deep learning. We design a novel multi-task learning method with feature-level fusion and a sharing mechanism. The proposed approach contains three parts: an image relighting subnetwork, a pedestrian detection subnetwork, and a feature-level multi-task fusion learning module. The image relighting subnetwork adjusts the low-light image quality for detection, the pedestrian detection subnetwork learns enhanced features for prediction, and the feature-level multi-task fusion learning module fuses and shares features among component networks for boosting image relighting and detection performance simultaneously. Experimental results show that the proposed approach consistently and significantly improves the performance of pedestrian detection on low-light images obtained by visible light imaging sensor.
An Elaborated Signal Model for Simultaneous Range and Vector Velocity Estimation in FMCW Radar
Authors: Ivanov Sergei , Kuptsov Vladimir , Badenko Vladimir , Fedotov Alexander
Published: October 2020

A rigorous mathematical description of the signal reflected from a moving object for radar monitoring tasks using linear frequency modulated continuous wave (LFMCW) microwave radars is proposed. The mathematical model is based on the quasi-relativistic vector transformation of coordinates and Lorentz time. The spatio-temporal structure of the echo signal was obtained taking into account the transverse component of the radar target speed, which made it possible to expand the boundaries of the range of measuring the range and speed of vehicles using LFMCW radars. An algorithm for the simultaneous estimation of the range, radial and transverse components of the velocity vector of an object from the observation data of the time series during one frame of the probing signal is proposed. For an automobile 77 GHz microwave LFMCW radar, a computer experiment was carried out to measure the range and velocity vector of a radar target using the developed mathematical model of the echo signal and an algorithm for estimating the motion parameters. The boundaries of the range for measuring the range and speed of the target are determined. The results of the performed computer experiment are in good agreement with the results of theoretical analysis.

Published: October 2020

Analysis of the dynamical regime changes in the stratosphere during different phases of the Sudden Stratospheric Warming (SSW) that has been observed in January 2013 is presented. The different mechanisms of SSW influence on the tropospheric circulation through the stationary planetary waves (SPWs) reflection and/or increase in SPWs activity due to nonlinear interaction with the mean flow and their subsequent propagation into the troposphere are discussed. Three-dimensional wave activity flux
and its divergence are determined using the UK Met Office data; the synoptic situation and its changes during the SSW events are analyzed. The wave activity penetrates downward from stratosphere into the troposphere and can affect weather processes during the SSW and right afterwards. It is this time that polar anticyclones can be formed at high latitudes, which quickly go southward along meridional directions and
then deviate to the East at middle latitudes. Interestingly, the locations of polar anticyclone formations and subsequent displacements correspond to the regions of maximal horizontal wave activity fluxes connected with stratospheric processes. The results obtained allow us to suggest that accounting of stratospheric processes and their influence on the troposphere in winter season can improve the middle-range forecast of anticyclone formation and cold weather events at middle latitudes.

A case of cooperative hunting by a pair of northern goshawks
Authors: Kusal Bartłomiej , Kajtoch Łukasz
Published: October 2020

Cooperative hunting is a rare strategy in raptors, although it has been widely described in Falconidae and in some species of Accipitridae. Records about synchronous hunting in the member of the genus Accipiter are occasional. Here we describe a case of the cooperative hunting of two northern goshawks, A. gentilis, of a pigeon, Columba sp., observed in southern Poland in 2020. This exemplary behavior could be either exceptional, or cooperative hunting is an overlooked phenomenon in goshawk biology.
La metáfora en la investigación
Authors: Giaccaglia Leticia
Published: October 2020

El propósito de estas reflexiones es pensar a la metáfora como herramienta para la investigación social. Una lectura de El Oficio del Sociólogo de Bourdieu y El Giro Semiótico de Fabbri me sugiere la existencia de posturas contrarias frente al uso de la metáfora. Bourdieu, por un lado, atrincherándose tras la necesidad en toda investigación, de una apropiada vigilancia epistemológica, agrega que es preciso, como  una de las técnicas que la garanticen, el  análisis de la lógica del lenguaje común que evite las significaciones dudosas a las que pueden exponernos las metáforas. Fabbri en cambio, afirma que la metáfora de igual modo que la inferencia silogística contribuye a la extensión del conocimiento. Puedo advertir entonces que en lo que Bourdieu ve una debilidad Fabbri señala una posibilidad. Entiendo que el planteo de Fabbri abre una puerta interesante que puede aportar y  hacerse extensiva a otras zonas de la investigación científica, a pesar de que su  propuesta atañe al campo de la semiótica. También, coincido con Bourdieu en la necesidad de  evitar tomar como datos, objetos preconstruidos por la lengua común, procurando su  construcción teórica. Esa construcción, sin embargo, no impide otorgarle a las metáforas status epistemológico, o, en otras palabras, aceptarlas como instrumentos que los investigadores puedan usar en función de los problemas y los objetivos que se plantean.

Published: October 2020

Aim: based on occlusion and temporomandibular health indicators, to improve clinical effectiveness of dental orthopedic treatment of patients with a need for a full mouth reconstruction.
Materials and methods. A total of 647 patients with adentia and a need for a full mouth reconstruction received comprehensive examination and treatment. Patients were divided into 3 groups. Group 1 (n=218) was exposed to standard treatment procedures. Group 2 (n=195) received certain elements of the interdisciplinary approach to dental orthopedic rehabilitation. Group 3 (n=234) was exposed to interdisciplinary approach towards dental orthopedic rehabilitation. The follow-up period was 7 years. A key step in the treatment of group 3 patients was to conduct full patient examinations sequentially. The corresponding procedures were supplemented with tests for temporomandibular disorder and occlusal relationships. In treatment planning, the cause-and-effect relationships between this disorder and malocclusion were identified.
Results. It was found that the use of the present proposal contributes to the normalization of occlusion. For instance, the occlusal index dropped 2.1-fold (relative to that in the comparison groups). The frequency of ICP manifestations decreased by 2.1 to 4.3 times, the protrusion frequency decreased by 12.2 to 22.3 times, and the bruxism frequency became 4.8 to 5.2 times lower. Furthermore, the frequency of left and right mediotrusion detection dropped by 3.2—4.3 and 3.8—4.4 times, respectively. The revealed changes were persistent, and a positive effect maintained throughout the follow-up.
Conclusion. The interdisciplinary approach to the restoration of the anatomical shape of teeth should involve the assessment and correction of occlusal disturbances.

This article presents an assessment of the quality of edge adhesion of cages of artificial crowns from disilicate lithium: 1) obtained with the help of CAD/CAM system from material E. max CAD; 2) obtained with the help of Cad/CAM system from ashless polymeric material C-Cast; 3) was produced using a 3D printer from ashless UV photopolymer material; 4) made by the traditional method of pressing, without the use of digital technologies.
The Image J computer program was used to study the quality of the edge gap of artificial crown frames.
For statistical analysis of the obtained data, the nonparametric H-Kruskel-Wallis test and the W-Mann-Whitney test were used.
We found that the average value of the edge gap between the stump of the experimental model and the frames of artificial crowns made in CAD/CAM ARCTICA from the E. max CAD material is 18.20±2.30 microns, from the polymer material C-Cast 22.50±1.37 microns. The average value of the edge gap between the stump of the tooth and the frames of artificial crowns made using the 3D printer Asiga Max UV is 22.35±1.59 microns. The average value of the edge gap between the tooth stump and the frames of artificial crowns made by traditional pressing method is 101.40±11.55 microns.
The results of our study indicate that the frames of artificial crowns made of lithium disilicate made with the help of modern digital technologies have a smaller edge gap compared to the frames of artificial crowns made by the traditional pressing method with a significance level of p<0,05 (h-Kruskel-Wallis criterion=30,865 p=0,0000009).
The thermodynamic formalism and exponents of singularity of invariant measure of circle maps with a single break
Authors: Dzhalilov A.A. , Karimov J.J.
Published: October 2020

Let $T \in C^{2+ \varepsilon} (S^{1} \setminus \{x_{b} \})$, $\varepsilon> 0 $, be a circle homeomorphism with one break point $x_{b}$, at which $ T'(x) $ has a discontinuity of the first kind and both one-sided derivatives at the point $x_{b} $ are strictly positive. Assume that the rotation number $\rho_{T}$ is irrational and its decomposition into a continued fraction beginning from a certain place coincides with the golden mean, i.e., $\rho_{T}=[m_{1}, m_{2}, \ldots, m_{l}, \, m_{l + 1}, \ldots] $, $ m_{s} = 1$, $s> l> 0$. Since the rotation number is irrational, the map $ T $ is strictly ergodic, that is, possesses a unique probability invariant measure $\mu_{T}$. A.A. Dzhalilov and K.M. Khanin proved that the probability invariant measure $ \mu_{G} $ of any circle homeomorphism $ G \in C^{2+ \varepsilon} (S^{1} \setminus \{x_{b} \})$, $\varepsilon> 0$, with one break point $ x_{b} $ and the irrational rotation number $ \rho_{G} $ is singular with respect to the Lebesgue measure $ \lambda $ on the circle, i.e., there is a measurable subset of $ A \subset S^{1} $ such that $ \mu_ {G} (A) = 1 $ and $ \lambda (A) = 0$. We will construct a thermodynamic formalism for homeomorphisms $ T_{b} \in C^{2+ \varepsilon} (S^{1} \setminus \{x_{b} \})$, $\varepsilon> 0 $, with one break at the point $ x_{b} $ and rotation number equal to the golden mean, i.e., $ \rho_{T}:= \frac {\sqrt{5} -1}{2} $. Using the constructed thermodynamic formalism, we study the exponents of singularity of the invariant measure $ \mu_{T} $ of homeomorphism $ T $.
Finite spectrum assignment in linear systems with several lumped and distributed delays by means of static output feedback
Authors: Kim I.G.
Published: October 2020

We consider a control system defined by a linear time-invariant system of differential equations with lumped and distributed delays in the state variable. We construct a controller for the system as linear static output feedback with lumped and distributed delays in the same nodes. We study a finite spectrum assignment problem for the closed-loop system. One needs to construct gain coefficients such that the characteristic function of the closed-loop system becomes a polynomial with arbitrary preassigned coefficients. We obtain conditions on coefficients of the system under which the criterion was found for solvability of the finite spectrum assignment problem. Corollaries on stabilization by linear static output feedback with several delays are obtained for the closed-loop system.
On a class of linear continuous-discrete systems with discrete memory
Authors: Maksimov V.P.
Published: October 2020

A class of linear functional differential systems with continuous and discrete times and discrete memory is considered. An explicit representation of the principal components to the general solution representation such as the fundamental matrix and the Cauchy operator is derived. The obtained representation is given in terms of the system parameters and opens a way towards efficient studying general linear boundary value problems and control problems with respect to a fixed collection of linear on-target functionals. In the study of the problems mentioned above outside the class under consideration, the systems with discrete memory can be employed as model or approximating ones. This can be useful as applied to systems with aftereffect under studying rough properties that hold under small perturbations of the parameters.
The meromorphic functions of completely regular growth on the upper half-plane
Authors: Malyutin K.G. , Kabanko M.V.
Published: October 2020

A strictly positive continuous unbounded increasing function $\gamma(r)$ on the half-axis $[0,+\infty)$ is called growth function. Let the growth function $\gamma(r)$ satisfies the condition $\gamma(2r)\leq M\gamma(r)$ for some $M>0$ and for all $r>0$. In the paper, the class $JM(\gamma(r))^o$ of meromorphic functions of completely regular growth on the upper half-plane with respect to the growth function $\gamma$ is considered. The criterion for the meromorphic function $f$ to belong to the space $JM(\gamma(r))^o$ is obtained. The definition of the indicator of function from the space $JM(\gamma(r))^o$ is introduced. It is proved that the indicator belongs to the space $\mathbf{L}^p[0,\pi]$ for all $p>1$.
On the regularization of the Lagrange principle and on the construction of the generalized minimizing sequences in convex constrained optimization problems
Authors: Sumin M.I.
Published: October 2020

We consider the regularization of the Lagrange principle (LP) in the convex constrained optimization problem with operator constraint-equality in a Hilbert space and with a finite number of functional inequality-constraints. The objective functional of the problem is not, generally speaking, strongly convex. The set of admissible elements of the problem is also embedded into a Hilbert space and is not assumed to be bounded. Obtaining a regularized LP is based on the dual regularization method and involves the use of two regularization parameters and two corresponding matching conditions at the same time. One of the regularization parameters is «responsible» for the regularization of the dual problem, while the other is contained in a strongly convex regularizing addition to the objective functional of the original problem. The main purpose of the regularized LP is the stable generation of generalized minimizing sequences that approximate the exact solution of the problem by function and by constraint, for the purpose of its practical stable solving.
On one control problem with disturbance and vectograms depending linearly on given sets
Authors: Ukhobotov V.I. , Ushakov V.N.
Published: October 2020

A control problem with a given end time is considered, in which the control vectograms and disturbance depend linearly on the given convex compact sets. A multivalued mapping of the phase space of the control problem to the linear normed space E is given. The goal of constructing a control is that at the end of the control process the fixed vector of the space E belongs to the image of the multivalued mapping for any admissible realization of the disturbance. A stable bridge is defined in terms of multivalued functions. The presented procedure constructs, according to a given multivalued function which is a stable bridge, a control that solves the problem. Explicit formulas are obtained that determine a stable bridge in the considered control problem. Conditions are found under which the constructed stable bridge is maximal. Some problems of group pursuit can be reduced to the considered control problem with disturbance. The article provides such an example.
Filters and linked families of sets
Authors: Chentsov A.G.
Published: October 2020

Properties of ultrafilters (u/f) and maximal linked systems (MLS) on the widely understood measurable space (MS) and representations of linked (not necessarily maximal) families and filters on this MS are investigated. Conditions realizing maximality of linked families (systems) and natural representations for bitopological spaces (BTS) of u/f and MLS are established. Equipments of sets of linked families and filters corresponding to Wallman and Stone schemes are studied; the connection of these equipments with analogous equipments (with topologies) for u/f and MLS leading to above-mentioned BTS is studied too. Properties of linked family products for two (widely understood) MS are investigated. It is shown that MLS on the π-system product (that is, on the family of “measurable” rectangles) are limited to products of corresponding MLS on initial spaces.
A modification of the hexahedral mesh generator based on voxel geometry representation
Authors: Karavaev A.S. , Kopysov S.P.
Published: October 2020

We consider a modification of the previously developed voxel-based mesh algorithm to generate models given in STL-geometry format. Proposed hexahedral mesh generator belongs to the family of grid methods, and is general-purpose in terms of a capability to use as source data both volume (voxel) and STL-surface representation of model geometry. For now, the algorithm works with CAD models described in the well-known STL format. However, it also allows to handle higher-order surface patches defined in an arbitrary format if appropriate procedures for projection and intersection operations will be specified. To define the initial position of mesh nodes, a “signed distance field” volume data file, obtained from the STL-geometry, is used. A special projection technique was developed to adapt constructed orthogonal mesh on the model's boundary. It provides an approximation of sharp edges and corners and is performed before running any other operations with the mesh. Finally, to improve the quality of the mesh, additional procedures were implemented, including boundary layers insertion, bad quality cells splitting, and optimization-based smoothing technique. The algorithm has been tested on a sufficient number of models, some of which are given as examples.
Validation of the model of adaptive control of the pedestrian flow movement in a dynamic space-limited environment
Authors: Kolodkin V.M. , Chirkov B.V.
Published: October 2020

The work is devoted to the validation of the model of adaptive control of the movement of pedestrian flows in a dynamic environment of limited space, which can be a building. An important case is considered in which the rates of change in the characteristics of the movement of a pedestrian flow and the state of the environment are close in magnitude. The concept of topological complexity is introduced to describe the inherent properties of a digital building model. Topological complexity characterizes the building from the position of connectedness of its elements. Validation is based on comparing the results of the evacuation of people from buildings obtained in the course of training fire alarms with the results of modeling the movement of pedestrian flows. When comparing, the time intervals for the release of buildings are compared. The experimental results are statistically significantly approximated by the regression model, which is used in validation. Validation made it possible to obtain a refinement coefficient of the digital model of the building, in which the results of modeling the movement of pedestrian flows correspond to the results of field observations. Validation of the model of controlled movement of pedestrian flows in a changing environment of limited space made it possible to use the model in a software and hardware complex for managing pedestrian flows, which operates in real-time advance mode.
Modeling of reasoning when searching for objects in images
Authors: Kuchuganov A.V. , Kasimov D.R. , Kuchuganov V.N.
Published: October 2020

Visual patterns, for example, handwritten letters or objects of aerospace observations, are highly variable. The high variety and large volume of unstructured information lead to the need for complex and resource-intensive calculations. Unfortunately, image analysis approaches based on the domain ontology do not specify any method for automatic selection of criteria (features) and decision-making rules. Insufficient structuredness of cases and a large variability of object images lead to a rapid growth of the case base, which significantly reduces the performance of the decision support system. The article proposes an approach to the structural analysis of images, which consists in sequential refinement of objects' features and weakening of interpretation rules during an iterative search of facts using the ontology of images represented as attributed graphs of relationships between elements of objects. The algorithm of reasoning on graphic information consists in the sequence of task (functional) actions necessary for processing and analyzing the image in accordance with the task, the actions of the system to prepare conditions for their implementation, as well as to organize and manage the reasoning process.
Refinement of the results of recognition of mathematical formulas using the Levenshtein distance
Authors: Saparov A.Yu. , Beltyukov A.P. , Maslov S.G.
Published: October 2020

The article deals with the problem of recognizing scanned mathematical texts with repeating formulas or formulas with same fragments. A method for comparing recognition results is described, which allows one to select similar elements from a variety of recognition options. The method is based on calculating the Levenshtein distances between individual fragments with additional parameters. The proposed method differs from the usual method in that, in the presence of uncertainties in comparison, all possible recognition options are used, presented as a symbol-weight pair. In the case of nonlinear formulas, numerical parameters that specify the location of individual symbols on the plane are also used in comparison. This comparison will allow you to group the formulas, and the data obtained will be useful in making decisions both by a user and by a program. Using this method will simplify the process of manual error correction, which will be based on the dynamic management of intermediate results in the process of close man-machine interaction.
Prevalence and determinants of mental distress during COVID-19 outbreak in Bangladesh: evidence from an online survey
Authors: Saha Shilpi Rani , Khan Dr. Md. Mobarak Hossain
Published: October 2020

Novel Coronavirus disease 2019 (COVID-19) is an ongoing pandemic and life-threatening highly infectious disease outbreak. The people of Bangladesh are at high risk of COVID-19 and have already experienced various socio-economic, Physical health, and psychological consequences. Particularly, mental health problems are dominantly reported in the literature and should be controlled. The main objective of this epidemiological study is to assess the mental distress and identify its determinants using an online-based survey. Such information is urgently needed to develop feasible strategies for Bangladesh. An online survey was conducted for this study from May 01 to May 05, 2020. A total of 240 respondents provided self-reported online responses. Respondent’s mental distress was measured by the General Health Questionnaire 12 (GHQ-12) and by the self-rated mental health (SRMH) questions. Various kinds of statistical analyses ranging from simple to multivariable logistic recession were performed using SPSS 23.0. About 31.3% and 48.3% of respondents were mentally distressed by GHQ-12 and SRMH questions, respectively. Logistic regression analysis revealed that mental distress was significantly higher among those respondents, whose usual activity was affected by the coronavirus (OR = 6.40, 95% CI: 1.87 - 21.90, p<0.001) and whose financial stress was increased due to lockdown (OR = 2.12, 95% CI: 1.01 – 4.46, p<0.05) on GHQ-12. Female sex (OR = 1.97, 95% CI: 1.03 – 3.75, p<0.05) and respondents with poor mental health before the outbreak (OR = 3.38, 95% CI: 1.18 – 9.72, p<0.05) were also significantly affected by mental distress on SRMH. At least thirty-one percent of the respondents were found to be mentally distressed. Some of the study findings, particularly significant determinants, should be considered while developing strategies to reduce the burden of mental distress among study respondents or similar groups.
Reliable Data Acquisition System for a Low-Cost Accelerograph Applied to Structural Health Monitoring
Authors: Muñoz Milton , Guevara Remigio , González Santiago , Jiménez Juan Carlos
Published: October 2020

This paper presents and evaluates a continuous recording system designed for a low-cost seismic station. The architecture has three main blocks. An accelerometer sensor based on MEMS technology (Microelectromechanical Systems), an SBC platform (Single Board Computer) with embedded Linux and a microcontroller device. In particular, the microcontroller represents the central component which operates as an intermediate agent to manage the communication between the accelerometer and the SBC block. This strategy allows the system for data acquisition in real time. On the other hand, the SBC platform is used for storing and processing data as well as in order to configure the remote communication with the station. This proposal is intended as a robust solution for structural health monitoring (i.e. in order to characterize the response of an infrastructure before, during and after a seismic event). The paper details the communication scheme between the system components, which has been minutely designed to ensure the samples are collected without information loss. Furthermore, for the experimental evaluation the station was located in the facilities on a relevant infrastructure, specifically a hydroelectric dam. The system operation was compared and verified with respect to a certified accelerograph station. Results prove that the continuous recording system operates successfully and allows for detecting seismic events according to requirements of structural health applications (i.e. detects events with a frequency of vibration less than 100 Hz). Specifically, through the system implemented it was possible to characterize the effect of a seismic event of 4 MD reported by the regional seismology network and with epicenter located about 30 Km of the hydroelectric dam. Particularly, the vibration frequencies detected on the infrastructure are in the range of 13 Hz and 29 Hz. Regarding the station performance, results from experiments reveals an average CPU load of 51%, consequently the processes configured on the SBC platform do not involve an overload. Finally, the average energy consumption of the station is close to 2.4 W, therefore autonomy provided by the backup system is aroud of 10 hours.

The composition of breast milk that we do not find in formula milk is an immune or antibody substance. Antibodies will provide protection against  some  bacteria,  one  of  which  is  the  bacteria  that  causes  ARI  (Acute  Respiratory  Tract Infection). The purpose of this study was to determine the long association of jbreastfeeding against the frequency  of  occurrence of  acute  respiratory  tract  infections  (ARI)  in  infants  6-12  months. The approach to be used in this study is an observational (cross sectional and retrospective) research approach. The sample used in this study was mothers who had toddlers aged 1-1.5 years who came to the posyandu in the working area of  the Ngadiluwih health center. The analysis test used is the Spearman Rank correlation test. The results of the study using the Spearman Rank analysis test obtained a significance value (P value) 0.028 <0.05, this means that there is a significant relationship between exclusive breastfeeding and the frequency of ARI in infants aged 0 -12 months, while the correlation coefficient (r) -1,27 negative sign indicates a unidirectional correlation, which means that mothers with exclusive breastfeeding will have babies who experience ARI with less frequency, and vice versa, mothers with no breastfeeding exclusive then the frequency of babies suffering from ARI will be more frequent. Things that can trigger the occurrence of various ARIs, exclusive breastfeeding may be one of our efforts to reduce the frequency of ARI in our baby.
