Comparative analysis of neurointerface technologies for the problem of their reasonable choice in human-machine information systems

The market of modern neurointerfaces, despite its active development, unfortunately, can offer users only a number of existing prototypes that have a relatively low accuracy and identification reliability of the human operator control effects. In addition, any neurointerface on the market must be individually tailored to each operator, which makes it difficult to objectify its accuracy, precision and reliability. The first step in solving the above problems is to conduct a comparative analysis of different price segments of the market of existing neurointerface technologies, as presented in this article. The market research revealed that despite the disadvantages of electroencephalography, it is one of the most accessible non-invasive methods of recording biological signals in neurointerface systems. To facilitate future research, the main advantages and disadvantages of known models and methods of signal analysis in neurointerfaces have been considered and analyzed. In particular, in the context of signal pre-processing, advantages and disadvantages of such methods as Common Average Referencing, Independent Component Analysis, Common Spatial Patterns, Surface Laplacian, Common Spatio-Spatial Patterns and Adaptive Filtering are considered. At the stage of evaluating the informative characteristics of the signal, the analysis of models and methods based on the models of adaptive parameters of autoregression, bilinear autoregression, multidimensional autoregression, fast Fourier transform, wavelet transformation, wave packet decomposition is performed. Besides, a comparative analysis of the most common methods of identification (recognition) of control effects of the human neurointerface operator, namely, the method of discriminant analysis, the method of reference vectors, nonlinear Bayesian classifiers, classifiers of nearest neighbors, artificial neural networks is carried out. The study of neurointerface technologies provides researchers with additional grounds for a sound choice of mathematical, software and hardware of neurointerface systems, as well as contributes to the development of new versions with increased accuracy, reliability and reliability.

Közúti infrastruktúra konfliktus-helyzete a magasan automatizált járművekkel

A közúti jelzések és a közlekedési infrastruktúra jelentősen befolyásolják a magasan automatizált vagy autonóm járművek viselkedését. Az automatizáltság azonban nem mindig jelent előnyt a jelenlegi köz-úti infrastruktúra vonatkozásában. Előfordulhat, hogy a magasan automatizált járművek szigorúbban betartják a közlekedési szabályokat, emiatt az önvezető funkciók váratlan beavatkozásokat hajthatnak végre a járművek haladása közben. Azonban ez sok esetben azért is jelenthet gondot, mert maguk a szabályok sem mindig megfelelők.
ENTREPRENEURIAL ENVIRONMENT AS AN ANTECEDENT OF UNIVERSITY STUDENTS’ ENTREPRENEURSHIP INTENTIONS

The primary purpose of the study was to develop a model for measuring entrepreneurship intentions among university art students. Therefore, the study investigated and attempted to answer the following question: To what extent does entrepreneurial environment affect the antecedents of entrepreneurial intention (Attitude towards entrepreneurship, subjective norm and perceived behavioural control? A sample of 150 graduates from the Arts and Design programme took part in the study and data collected was analysed using Structural Equation Modelling (SEM). The results provide evidence that subjective norm is an insignificant predictor of entrepreneurial intention compared to attitudes towards entrepreneurial behaviour and entrepreneurial self-efficacy. Perceived environment support was observed to directly relate to future Entrepreneurial Intentions and it also mediates the relationship between Perceived University Environment, Perceived Entrepreneurial Abilities and immediate Entrepreneurial Intentions. It is recommended that policymakers should consider the development of a coherent national policy framework that addresses entrepreneurship for the art/creative industries sector. Future research is recommended to fully evaluate the effectiveness of the impact that subject components in Entrepreneurship Education have on students’ attitudes towards entrepreneurship, perceived entrepreneurial abilities, and Entrepreneurial Intentions.
Feasibility of a Multidisciplinary Lifestyle Program for Obese Patients With Atrial Fibrillation

Aims: Atrial Fibrillation (AF) is often associated with obesity. The effects of traditional lifestyle programs are often not maintained in the longer term effects because the programs do not sufficiently focus on behavioral change. We want to study the feasibility of a multidisciplinary lifestyle program, cardiac rehabilitation (CR) focusing on behavioral change in patients with AF and obesity. Methods and results: Patients received CR for three months including exercise training, lifestyle counseling by an Advanced Nursing Specialist, dietary advice and psychosocial therapy when deemed necessary. Main endpoints were weight loss and burden of AF (AFSS questionnaire). Secondary endpoints were physical fitness (6MWT), depression (PHQ9) and anxiety (GAD7). Measurements were performed at baseline and post-CR. Weight and 6MWT were also assessed at 1-year follow-up. After following a lifestyle program, patients improved their weight and physical condition, and were less symptomatic. The frequency of AF-related symptoms was considerably reduced immediately after rehabilitation and was even lower after 1 year. The severity of AF complaints post-CR was similar to the baseline, but significantly lower after 1 year. Conclusion: A multidisciplinary lifestyle program with an emphasis on structural lifestyle improvement is feasible for obese patients with AF and potentially effective in reducing symptoms, weight and physical fitness, thereby decreasing the burden of AF.
Performance Analysis of Automatic Generation Control of Multi-Area Restructured Power System

This paper deals with the automatic generation control (AGC) scheme for the interconnected multi-area, multi-source power generation in the deregulated power system. Here, in this paper, the conventional multi-area AGC system has been modified to the restructured power system with the GENCOs, DISCOs, and TRANCOs. Different unilateral and bilateral contracts have been carried out using integral control scheme. From the obtained simulation results it has been found that the control scheme is presenting an effective method to facilitate the load frequency control (LFC) in a restructured power system.
An approach for measuring spatial similarity among COVID-19 epicenters

ABSTRACT Most countries and territories worldwide are affected by coronavirus disease 2019 (COVID-19), and some cities have become known as epicenters owing to high outbreaks. Because of the changeable and unknown nature of the virus, managers of different cities could learn from the experiences of cities that have been successful in controlling COVID-19 instead of wasting time exploring different methods. It would be even more beneficial if they analyzed the experiences of similar cities. The similarity of such cities could be examined within a geographic information system based on various criteria. This study investigated the similarities among eight cities – Wuhan, Tehran, Bergamo, Madrid, Paris, Daegu, New York, and Berlin – in terms of the COVID-19 situation (target) in these locations based on proximity factors, weather, and demographic criteria. First, the factor and target layers were prepared, and then similar cities were identified using a similarity model and different distance metrics. The results were aggregated using the Copeland method because of the different outcomes for each metric. The most similar city was identified for each selected city, and its similarity level was determined based on these criteria. The results suggested the following pairs of similar cities: Wuhan–Berlin, Tehran–Berlin, Daegu–Wuhan, Bergamo–Madrid, Paris–Madrid, and New York–Paris based on COVID-19 related data up to 15 April 2020 (target T1), and Daegu–Wuhan, Tehran–Madrid, Bergamo–Paris, Berlin–Paris, and New York–Madrid up to 8 December 2021 (target T2) with a minimum and maximum similarity rate of 82.85% and 92.36%, respectively. For similar cities, the most similar factors among the proximity criteria are the distance from bus and metro stations; among weather, the criteria are humidity and pressure; and among demographics, the criteria are male and female population ratios, literacy ratio, and death ratio from asthma and cancer, with a minimum and maximum difference of 0% and 64.94%, respectively. In addition, according to the random forests ranking results (with root mean squared error = 0.23), temperature, distance from the bank, and gender were the most important criteria for the eight studied cities. Identifying these important factors helps to determine hotspots or places of future outbreaks to choose control strategies according to the cultural and ecological conditions of each city.

The Change of Cervical Spine Alignment Along with BMI in Asymptomatic Population: A Preliminary Analysis

Study design: A cross-sectional studyObjective:Describe the difference in the cervical sagittal alignment between various BMI people.Summary of Background Data:Cervical sagittal imbalance is implicated in the development of various spinal disorders, and obesity was recognized as a global epidemic. But there were few studies focusing on the correlation between cervical sagittal alignment and body mass index (BMI). Methods: This study enrolled 140 asymptomatic volunteers from July 2016 to July 2019. Demographic data included gender, age and BMI, and radiographic parameters included chin–brow vertical angle (CBVA), occipital slope (OS), orbital tilt (OrT), orbital index (OI), occiput-C2 lordosis (O-C2), cervical lordosis (CL), C2-C7 sagittal vertical axis (C2-C7SVA) , cranial tilting (CrT), cervical tilting (CeT), T1 slope (TS), neck tilt (NT), and thoracic inlet angle (TIA). The data were analyzed by ANOVA statistical analyses.Results: In terms of the occipitocervical parameters, we found that there was no significant difference (OS, P=0.970; OrT, P=0.970; OI, P=0.798); In terms of cervical parameters, we found significant correlations between BMI and parameters (C2-C7SVA, P=0.005; TZC2-C7, P=0.030; CrT, P= 0.050; CeT, P=0.013), which reflected that forward head posture increases as BMI rises; In terms of thoracic parameters, we also found significant correlations between BMI and parameters (NT, P=0.014; TIA, P=0.050), which reflected that thoracic inlet lifts as BMI rises.Conclusions: We found that there are the correlations between cervical sagittal alignment (C2-C7SVA, TZC2-C7, CL, CrT, and CeT) and BMI, and forward head posture increases and thoracic inlet lifts in the obese, which can provide clinical advice and remind surgeons of BMI effect in reconstructive surgery for better prognoses.
Proprioceptive training and sports performance

One of the current trends in the field of sports training concerns the integration into training programs of exercises defined as "proprioceptive", which also include balance exercises, used to optimize performance, prevention or recovery from injuries. After introducing and describing the main characteristics of proprioceptive training in sports, the present review aims to set out and analyse the various flaws in this type of training as it is commonly practiced, in order to lay the groundwork for future improvements in proprioceptive training. Our research highlights that it is common practice to combine proprioceptive training with training on unstable surfaces, generally meaning the same for both situations. Such practices are indicative of the confusion surrounding the concepts of proprioception and balance. Indeed, until these two concepts and their respective performance benefits are clearly differentiated, it will be difficult to move beyond the controversy surrounding proprioceptive training and hence. to make advances in the field of proprioceptive training research. In conclusion, therefore, against the comforting theories that accompany the use of proprioceptive training in relation to the improvement of performance, unfortunately there is a literature that shows many variables not yet considered or treated in an approximate way.

Simplifying Enzymatic Biofuel Cells: Immobilized Naphthoquinone as a Biocathodic Orientational Moiety and Bioanodic Electron Mediator

An elegant method to perform bioelectocatalysis with different oxidoreductases at the cathode and at the anode of an enzymatic biofuel cell is presented. Noncovalent functionalization of multiwalled carbon nanotubes (MWCNTs) was accomplished via π–π interactions of pyrene derivatives. 1-[Bis(2-naphthoquinonyl)aminomethyl]pyrene was synthesized and successfully immobilized on MWCNTs. The incorporation of the quinone-modified MWCNTs within enzymatic bioelectrocatalytic applications was evaluated. The hydrophobic nature of the naphthoquinone aided orientation of laccase and bilirubin oxidase toward the electrode, which enhanced their ability to undergo the direct bioelectrocatalysis of oxygen. In contrast, the electrochemical properties of the quinone were used at the bioanode to mediate electrons from the bioelectrocatalytic oxidation of glucose by pyrroloquinoline quinone-dependent glucose dehydrogenase. This method demonstrates how the smart modification of MWCNTs can develop materials, which can be used .
A genome-wide screening for RNAi pathway genes in Acari

BackgroundRNA interference (RNAi) is a highly conserved, sequence-specific gene silencing mechanism present in Eukaryotes. Three RNAi pathways critical for organismal development and survival are known, namely micro-RNA (miRNA), Piwi-interacting RNA (piRNA) and short interfering RNA (siRNA) pathways. Little knowledge exist about the genes involved in these pathways in Acari. Moreover, variable successes has been obtained in gene knockdown via siRNA pathway in functional genomics and management of Acari species. We hypothesized that the clue may be in the variability in the composition and the efficacy of siRNAi machinery among Acari. ResultsBoth comparative genomic analyses and domain annotation suggest that all the analyzed species have orthologs of genes that mediate gene silencing via the three RNAi pathways though gene duplication and/or loss have occurred in the different species. We also identified orthologs of Caenorhabditis elegans RNA-dependent RNA polymerase (RdRP) gene in all Acari species though no secondary Argonaute homologs that operate with this gene in siRNA amplification mechanism were found. This finding suggests that the siRNA amplification mechanism present in Acari may be distinct from that described in C. elegans. Moreover, the genomes of these Acari species encode no ortholog of C. elegans systemic RNAi defective 1 (Sid-1) that mediate systemic RNAi, suggesting that the phenomena of systemic and parental RNAi that has been reported in some Acari species probably occur through a different mechanism. Orthologs of RNAi spreading defective-3 (Rsd-3) gene and scavenger receptors namely Eater and SR-CI that mediate endocytosis cellular update of dsRNA in C. elegans and Drosophila melanogaster were found in Acari genomes. This result suggests that cellular dsRNA uptake in Acari is endocytosis-dependent. Detailed phylogenetic analyses of core RNAi pathway genes in the studied Acari species revealed that their evolution is compatible with the proposed monophyletic evolution of this group.ConclusionsTaken together, our in silico comparative analyses have revealed the potential activity of all three pathways in Acari. However, much experimental work remains to be done in elucidating the operating mechanisms behind these pathways in particular those that govern systemic/parental RNAi and siRNA amplification in Acari.
