Authors: Wu Yongmei , Liang Le , Xie Yongdong , Tang Yi , Liu Lei
Published: November 2019

To investigate the effects of cadmium (Cd) stress on the growth of different tomato rootstocks, the Cd content and transport efficient of rootstocks, the pot experiment was carried out with wild eggplant rootstocks Solanum torvum and Totosga, tomato rootstock “Dalishengen”, “Banzhen18” and “Guozhen1”. Under Cd stress, the plant heights of “Banzhe18” and “Dalishengen” were significantly higher than other; the main root lengths of Totosga and S. torvum were significantly longer than other. The dry weight of the “Banzhen18” was the highest, and the “Guozhen1” was the smallest. The order of Cd content in roots was S. torvum > Totosga > “Guozhen1” > “Banzhen18” > “Dalishengen”; the content of Cd in the stem of “Dalishengen” was the highest, and Totosga was the least. The order of Cd content in leaves was “Guozhen1” > “Dalishengen” > “Banzhen18” > Totosga > S. torvum. S. torvum had the smallest translocation factor, and “Dalishengen” had the biggest. Cd stress showed significant inter-specific differences in rootstock growth and Cd content. The plant height of tomato rootstock was significantly higher than the wild eggplant rootstock, and the main root length of wild eggplant rootstock was significantly longer than tomato rootstock. The Cd contents in S. torvum and Totosga mainly accumulated in the roots, so the Cd content in the aerial part was much lower than other.

Published: November 2019

This paper studies the network structure of geographical indication agricultural products in the field of e-commerce in Sichuan Province, and discusses the joint mechanism of geographical indication brands based on network structure. Taking the geographical indication products as the node, the consumer’s purchase behavior is the connection relationship, and the network structure of the geographical indication products is analyzed from the perspective of consumer behavior, and then the regional brand creation is based on this.This paper constructed a product——product network——brand alliance——regional brand geographical indication agricultural product regional brand creation path. The paper focuses on the resource dependent brand joint behavior based on individual interests, and the joint behavior of geographically dependent brands based on the perspective of regional interests. When the brand joint starting point is based on individual interests, it will tend to choose resource-based agricultural product brands that have strong commodity-related strength and can bring the greatest consumer transformation to themselves; when the brand joint starting point is to promote the regional-based regional economy, it will tend to start from the cluster-based brand alliance, emphasizing the development of a good geographical indication agricultural product brand to promote the development of a geographically-improved GI brand.
Analysis of microstructure and difference of 6 species of remiges in Galliformes
Authors: Jiang Jing
Published: November 2019

To study the microstructure and difference of remiges in galliformes, the Silver Pheasant (Lophura nycthemera), golden pheasant (Chrysolophus pictus), Blue Eared Pheasant (Crossptilon auritum), Koklass Pheasant (Pucrasia macrolopha), Himalayan Snowcock (Tetraogallus himalayensis) and Thunderbird (Tetrao urogallus) were selected as the representative of six species of endangered birds. The scanning electron microscopy (SEM) was adopted to photograph and count the hooked barbule, cilia and ventral tooth, meanwhile, the single factor analysis of variance of different remiges was carried out by Spss 11.5 software. The results show that remiges are mainly composed of hook feathers and proximal barbule, and there are hook feathers on the side of a small hook, but also with cilia. Proximal barbule is mainly composed of ventral tooth, whose number and shape are the main features. The number of hooked barbule, cilia and ventral tooth of proximal barbule of the remiges of the different birds were significantly different or significant differences among the two species, which could provide the basis for identification.
Charming loops in exclusive rare FCNC B-decays
Authors: Melikhov Dmitri
Published: November 2019

Rare B-decays induced by flavour-changing neutral currents (FCNC) is one of the promising candidates for probing physics beyond the Standard model. However, for identifying potential new physics from the data, reliable control over QCD contributions is necessary. We focus on one of such QCD contributions – the charming loops – that potentially can lead to difficulties in disentangling new physics effects from the observable and discuss the possibility to gain control over theoretical predictions for charming loops.
Neutrino evolution in dense matter and electromagnetic field
Authors: Chukhnova A. V. , Lobanov A. E.
Published: November 2019

Neutrino evolution in dense matter and electromagnetic field is studied within quantum-field theoretical description on the base of a modification of the Standard Model, where the neutrinos are combined in S U(3)-multiplets. A quantum wave equation for neutrino in matter and electromagnetic field is obtained. In quasi-classical approximation a general method for calculating the probabilities of different spin-flavor transitions of neutrino in constant homogeneous field and moving matter with constant polarization is developed. In two-flavor model the explicit form of the solutions is obtained in constant electromagnetic field taking into account the transition magnetic moments. The obtained spin-flavor transition probabilities are compared to the results for unpolarized moving matter.
Equations of quantum theory in the space of randomly joint quantum events
Authors: Biryukov Alexander
Published: November 2019

The dynamics of the system in the space of random joint events is considered. The symmetric difference of events is introduced in space based on the Kolmogorov axioms. To describe quantum effects in the dynamics of the system, an additional axiom is introduced for random joint events: “the symmetric sum of random events.” In the generated space of random joint events, an equation is constructed for the probability of a system transition between two events. It is shown that for pairwise joint events it is equivalent to the equation of quantum mechanics.

Zero-range potential in the model of the spinor field interacting with a material plane: conditions for transparency of the plane to Dirac particles
Authors: Pismak Yu. M.
Published: November 2019

In the model of interaction of a spinor field with a homogeneous isotropic material plane, the possibility of the passage of a Dirac particle through it without reflection and a change in polarization isstudied. The model was proposed earlier in the framework of the Symanzik approach to describe the interaction of spinor quantum fields with two-dimensional materials. In its framework the scattering processes of Dirac particles and the properties of their bound states were investigated. In this paper, we study the conditions under which the plane is completely transparent to the particles. A description of the region of model parameters characterizing the properties of the plane material is obtained explicitlyand given in the article, as well as expressions in terms of these parameters for the momentum and polarization of the particle at which interaction with the plane does not affect its movement.

Authors: Mandrik Petr
Published: November 2019

The study of the anomalous non-resonant HH production is presented from the point of view of effective field theory (EFT) parameterization. The searches for pp → HH → γγWW, pp → HH → γγbb and pp → HH → bbbb processes by ATLAS experiment at the Large Hadron Collider (LHC) are reproduced. The selection efficiencies and exclusion limits on the HH production cross for different Beyond Standard Model (BSM) EFT benchmark models are obtained using the fast Monte-Carlo simulation of the ATLAS detector.
Signed domination and Mycielski’s structure in graphs

Published: November 2019

LetG = (V, E) be a graph. The functionf : V(G) → {−1, 1} is a signed dominating function if for every vertexv ∈ V(G), ∑x∈NG[v]f(x)≥1. The value ofω(f) = ∑x∈V(G)f(x) is called the weight off. The signed domination number ofGis the minimum weight of a signed dominating function ofG. In this paper, we initiate the study of the signed domination numbers of Mycielski graphs and find some upper bounds for this parameter. We also calculate the signed domination number of the Mycielski graph when the underlying graph is a star, a wheel, a fan, a Dutch windmill, a cycle, a path or a complete bipartite graph.
“Acorns and berries afford me sufficient nourishment”: an ecocritical reading of the monstrous in Mary Shelley’s Frankenstein and Patrick Ness’s A Monster Calls
Authors: Hansen Mascha
Published: November 2019

Monster stories, however old they may be, still prove to be very fruitful when read in an ecocritical context. Monsters can be saviours, too: they have not yet lost their warning powers, and they still sneak around in modern retellings of the myths that prove how dire the consequences of wasting resources have long been in our story-telling traditions. Thus, the monstrous clearly offers powerful, anxiety-inducing images that must be of interest in contemporary attempts to revise our story-telling to a more eco-friendly mode. Indeed, Frankenstein’s monster, a vegetarian proud to be able to live without consuming animal food, a being torn between wanting to do good but committing evil instead, may be said to embody contemporary environmental concerns. If we read the monster as a natural “Being” (to use Percy Shelley’s term), however unnaturally created, he takes on a different role, one that ties him to the myth of Prometheus in ways that have not yet been explored. Moreover, he does have overtones of the Green Man, too, and in that shape, he can be connected to a more recent monster, that employed by Patrick Ness in A Monster Calls. Monsters, no doubt about it, are scary creatures when they make us face the truth about who we are, and what we do to the earth. This paper considers some of the tensions raised by the paradox of the monstrous ‘saviour’ from an ecocritical perspective.

We describe the Fourier Transform Spectrometer (FTS) used for in-field testing of the POLARBEAR receiver, an experiment located in the Atacama Desert of Chile which measures the cosmic microwave background (CMB) polarization. The POLARBEAR-FTS (PB-FTS) is a Martin-Puplett interferometer designed to couple to the Huan Tran Telescope (HTT) on which the POLARBEAR receiver is installed. The PB-FTS measured the spectral response of the POLARBEAR receiver with signal-to-noise ratio >20 for ∼69% of the focal plane detectors due to three features: a high throughput of 15.1 sr cm2, optimized optical coupling to the POLARBEAR optics using a custom designed output parabolic mirror, and a continuously modulated output polarizer. The PB-FTS parabolic mirror is designed to mimic the shape of the 2.5 m-diameter HTT primary reflector, which allows for optimum optical coupling to the POLARBEAR receiver, reducing aberrations and systematics. One polarizing grid is placed at the output of the PB-FTS and modulated via continuous rotation. This modulation allows for decomposition of the signal into different harmonics that can be used to probe potentially pernicious sources of systematic error in a polarization-sensitive instrument. The high throughput and continuous output polarizer modulation features are unique compared to other FTS calibrators used in the CMB field. In-field characterization of the POLARBEAR receiver was accomplished using the PB-FTS in April 2014. We discuss the design, construction, and operation of the PB-FTS and present the spectral characterization of the POLARBEAR receiver. We introduce future applications for the PB-FTS in the next-generation CMB experiment, the Simons Array.
Østerild: A natural laboratory for atmospheric turbulence
Authors: Peña A.
Published: November 2019

Understanding atmospheric turbulence is without a doubt one of the most complex subjects in meteorology. However, its behavior can be more easily investigated by analysis of high-quality measurements of the velocity and temperature fluctuations. Here, we show that at the large test station of wind turbines in Østerild, northern Denmark, measurements from a 250-m lightning mast provide unique insights into the behavior of atmospheric turbulence within the range of heights where modern large wind turbines operate. We illustrate that for the predominant westerly winds at the site, the flow can be assumed to be close to homogeneous. This allows the analysis of the behavior with atmospheric stability and height of the wind speed and direction and of different turbulence measures, i.a., velocity variances and covariances, as well as turbulence spectra and their characteristics. It is shown, e.g., that for a wide range of atmospheric stability conditions, turbulence parameters up to 241 m are directly related to mean flow characteristics, which will aid in improving the simulation of turbulence in, i.a., aeroelastic simulations. These measurements can be used for the evaluation of a wide range of models describing the meteorological conditions and the atmospheric flow and its turbulent behavior.
Demonstration of a 6 state-4 state reference frame independent channel for quantum key distribution
Authors: Tannous Ramy , Ye Zhangdong , Jin Jeongwan , Kuntz Katanya B. , Lütkenhaus Norbert , Jennewein Thomas
Published: November 2019

We study a reference frame independent (RFI) quantum key distribution (QKD) protocol using six states for Alice and only four states for Bob, while previous RFI protocols require a six state analyzer for Bob. Our protocol can generate a secure key for any possible phase of the entangled state provided the variation is small compared to the measurement rate, as shown by our numerical key rate analysis. We perform a proof-of-principle experiment using polarization entangled photon pairs. In the presence of a varying rotational phase, we obtain a consistently low error rate of less than 4%, indicating the feasibility of this protocol for QKD. Our RFI protocol is hence beneficial but not limited to applications in a satellite or mobile free-space QKD, where a communication node must limit the resources and restrict the number of measured states to four instead of six.
Simulation of collision-induced absorption spectra based on classical trajectories and ab initio potential and induced dipole surfaces. I. Case study of N2–N2 rototranslational band
Authors: Chistikov Daniil N. , Finenko Artem A. , Lokshtanov Sergei E. , Petrov Sergey V. , Vigasin Andrey A.
Published: November 2019

This paper presents theoretical formalism and some results of the collision-induced absorption (CIA) spectral simulation based on the classical trajectory analysis. Our consideration relies on the use of ab initio potential energy and dipole moment surfaces for two interacting rigid monomers. Rigorous intermolecular Hamiltonian is represented and used in the body-fixed reference frame. The complete set of dynamical equations with Boltzmann-weighted initial conditions is solved to render a large number of classical trajectories. The spectral shape is calculated as an ensemble-averaged Fourier spectrum issued from the time-dependent induced dipole along individual scattering trajectories. Considering a pair of N2 molecules as an example, we have calculated the rototranslational CIA band profiles at T = 78, 89, 109, 129, 149, 179, 228, 300, and 343 K. The classical trajectory-based spectral shape was corrected to satisfy the quantum principle of detailed balance. Good accuracy of our semiclassical approach was demonstrated by comparison with available experimental data as well as with results of the previously published purely quantum simulation by Karman et al. [J. Chem. Phys. 142, 084306 (2015)] in which the same ab initio calculated N2–N2 potential energy and induced dipole moment surfaces were used.

Single crystals of potassium titanyl phosphate (KTiOPO4, KTP) family (MTiOXO4, where M is K, Rb, or Cs, and X is P or As) with periodical domain structures have emerged as one of the key platforms for enabling nonlinear photonics applications. Potassium titanyl arsenate (KTiOAsO4, KTA) crystals possess nonlinear optical properties outperforming those of KTP. However, domain kinetics in KTA, being the crucial element for periodical poling, lacks comprehensive studies. We present the results of in situ imaging of domain kinetics in KTA with high temporal resolution. The analysis of a set of instantaneous domain structure images (kinetic map) has allowed reliable revealing of the slow and fast domain walls, similar to KTP. The mobility and the threshold fields for the domain walls have been estimated. The main stages of the domain structure evolution have been revealed. The original hatching stage representing the formation of quasiperiodic structure of the narrow stripe domains has been discovered. The relative input of the hatching stage has increased with external field. The obtained qualitative difference in the domain structure evolution, compared with KTP, has been attributed to a six times larger ratio of fast to slow wall mobility in KTA. This fact results in suppression of the undesirable broadening of the stripe domains thus making KTA crystals very attractive for periodical poling.

Huntington’s disease (HD) is a chronic neurodegenerative disorder characterized by a late clinical onset despite ubiquitous expression of the mutant Huntingtin gene (
HTT
) from birth. Transcriptional dysregulation is a pivotal feature of HD. Yet, the genes that are altered in the prodromal period and their regulators, which present opportunities for therapeutic intervention, remain to be elucidated. Using transcriptional and chromatin profiling, we found aberrant transcription and changes in histone H3K27acetylation in the striatum of R6/1 mice during the presymptomatic disease stages. Integrating these data, we identified the Elk-1 transcription factor as a candidate regulator of prodromal changes in HD. Exogenous expression of Elk-1 exerted beneficial effects in a primary striatal cell culture model of HD, and adeno-associated virus-mediated Elk-1 overexpression alleviated transcriptional dysregulation in R6/1 mice. Collectively, our work demonstrates that aberrant gene expression precedes overt disease onset in HD, identifies the Elk-1 transcription factor as a key regulator linked to early epigenetic and transcriptional changes in HD, and presents evidence for Elk-1 as a target for alleviating molecular pathology in HD.
Clustering and dynamics of crowded proteins near membranes and their influence on membrane bending
Authors: Nawrocki Grzegorz , Im Wonpil , Sugita Yuji , Feig Michael
Published: November 2019

Atomistic molecular dynamics simulations of concentrated protein solutions in the presence of a phospholipid bilayer are presented to gain insights into the dynamics and interactions at the cytosol–membrane interface. The main finding is that proteins that are not known to specifically interact with membranes are preferentially excluded from the membrane, leaving a depletion zone near the membrane surface. As a consequence, effective protein concentrations increase, leading to increased protein contacts and clustering, whereas protein diffusion becomes faster near the membrane for proteins that do occasionally enter the depletion zone. Since protein–membrane contacts are infrequent and short-lived in this study, the structure of the lipid bilayer remains largely unaffected by the crowded protein solution, but when proteins do contact lipid head groups, small but statistically significant local membrane curvature is induced, on average.
Self-identity barcodes encoded by six expansive polymorphic toxin families discriminate kin in myxobacteria
Authors: Vassallo Christopher N. , Wall Daniel
Published: November 2019

Significance

Social organisms that share resources must identify their kin to avoid exploitation by nonself competitors; however, underlying mechanisms to explain discrimination are lacking. Myxobacteria, which aggregate into tissue-like groups, use a 2-step self-identification mechanism in which cells interact by a highly variable cell surface receptor that catalyzes cellular cargo exchange. This cargo includes polymorphic toxins that poison nonclonal cells, which lack specific immunity genes. Here, we identified 6 unique families of toxins that are strikingly numerous in myxobacterial genomes. Together, arrays of toxins form what we describe as self-identity barcodes that exquisitely distinguish clonal cooperators from nonself. This work highlights how selfish and discriminating genes, which expand in vast combinations in bacterial genomes, help to diversify and insulate social groups.

Significance

Deletion of fatty acid amide hydrolase (FAAH) in mice results in the concomitant elevation of 2 major types of fatty acid amides,
N
-acylethanolamines (NAEs) and
N
-acyl taurines (NATs), as well as obesity, hyperphagia, and insulin resistance. However, the respective contribution of each class of fatty acid amide to these phenotypes is unresolved. Here we employ an engineered variant of FAAH to specifically elevate NATs in vivo and administer the predominant circulating human NAT species to mice, demonstrating that NATs improve insulin sensitivity and augment secretion of the antidiabetic hormone GLP-1. These findings expose a divergent role for FAAH substrates in the regulation of glucose homeostasis, informing future efforts to target fatty acid amide signaling to treat metabolic disease.

Published: November 2019

Lysyl oxidase (LOX) is required for the formation of bone collagen cross-links. Inactivation of the LOX gene in osteoblasts by DNA methylation and JAK signaling has been reported to cause loss of cross-links and an increased risk of fractures. Tocotrienols (T3s) have proven benefits on bone strength, but their potential effects on LOX remain largely unknown. Thus, the present study investigates the in vitro effects of T3s on LOX expression in human osteoblastic MG-63 cells. Results indicated that Tocotrienol-Rich Fraction (TRF), the δ-T3 rich oil extracted from Annatto was the most effective and significantly increased LOX expression. TRF treatment decreased de-novo methyltransferases (DNMTs), DNMT3A and DNMT3B levels. In addition, TRF significantly inhibited JAK2 activation and decreased expression of Fli1, a transcription factor of DNMTs. We conclude that TRF induced an increase in LOX expression via inhibition of de-novo methylation and reduction of Fli1 expression by the inactivation of JAK2.

Published: November 2019

Potassium ion conduction through open potassium channels is essential to control of membrane potentials in all cells. To elucidate the open conformation and hence the mechanism of K+ion conduction in the classic inward rectifier Kir2.2, we introduced a negative charge (G178D) at the crossing point of the inner helix bundle, the location of ligand-dependent gating. This “forced open” mutation generated channels that were active even in the complete absence of phosphatidylinositol-4,5-bisphosphate (PIP2), an otherwise essential ligand for Kir channel opening. Crystal structures were obtained at a resolution of 3.6 Å without PIP2bound, or 2.8 Å in complex with PIP2. The latter revealed a slight widening at the helix bundle crossing (HBC) through backbone movement. MD simulations showed that subsequent spontaneous wetting of the pore through the HBC gate region allowed K+ion movement across the HBC and conduction through the channel. Further simulations reveal atomistic details of the opening process and highlight the role of pore-lining acidic residues in K+conduction through Kir2 channels.
After After Lorca: Anamnesis and Magic between Jack Spicer and Federico García Lorca
Authors: Shoemaker Robert Eric
Published: November 2019

This essay will examine the work of Jack Spicer through the lens of Federico García Lorca’s homages and his concept of the dark earth inspiration called duende to explore the bonds created through imagined lovers, mostly looking at works proposing relationship through affect, apostrophe, and homoerotics. Spicer communicated with García Lorca in his book After Lorca, which Spicer saw as a direct channeling of the poet and his magic-imbued poetics via translation. In Spicer’s work, anamnesis and homage are attempts to unify the writer with the object of channeling—the “same-like” person with whom the author identifies. The act of imagining or channeling a similar writer into conversation provides a direct link to creativity for Spicer and others like him, who write in the vein of queer magic in order to create and perpetuate lineage and connection to the sexual world despite distances of time and space. Uncovering this perspective within the writings of García Lorca and Spicer allows a deeper and more empathetic rereading of both as queer poets and poets interested in writing-as-magic. This likewise encourages a deeper and fuller imitation of these writers by contemporary kin working into queer lineages.
Making Sense of Facebook’s Content Moderation: A Posthumanist Perspective on Communicative Competence and Internet Memes
Authors: Procházka Ondřej
Published: November 2019

This article focuses on how Facebook users understand and adapt to or resist recently increasing intensity in Facebook content-curating practices in pages organized around geopolitical satire memes generally known as “Countryball comics.” Participants attach a ludic, nonserious discursive and communal ethos to potentially offensive memes, by which they create a type of sociality that faces punitive actions from Facebook (content deletion and publishing suspensions). Following meta-level discussions about correctness, appropriateness, and acceptability, participants feel compelled to adjust their communicative behavior in ways ranging from self-censorship to altering communicative practices native to such meme pages. Moreover, participants construe Facebook as a composite human (Facebook users and content moderators) and algorithm-driven nonhuman (automated content recognition tools and filters) entity actively involved and embedded in everyday communication. Drawing on posthumanist sociolinguistics and applied linguistics (Pennycook 2016, 2018), the article revisits the traditional notion of “communicative competence” to account for the dynamic interplay between dispersed, disembodied, and (non-)human interactants, environment, and artifacts.

It is based on a handheld probe station, a vector network analyzer, a vector signal analyzer and a signal generator. It provides automation of research and determination of the main parameters of microwave filters – amplitude-frequency characteristics, phase-frequency response, group delay differences, level signal attenuation in stop band. The function of documenting the results of measuring the parameters of microwave filters allows not only in real time, but also in post-processing to analyze and compare the characteristics of microwave filters in the frequency range from 10 MHz to 24 GHz.

Published: November 2019

The paper studies the problem of determining the lower boundary of number correction speed in computing systems operating in the basis of non-positional arithmetic in residual classes. The topicality of the problem is necessitated by the search of methods allowing reducing the time for digital processing of signals in non-positional neuroprocessors. The work considers the variants for error correction with single and multiple control bases of the residue system. The proof is provided that allows justifying the adequacy of the modified method that implements paired zeroing of numbers in the system of residual classes. It was shown that the suggested solutions allow considerably reducing the time expenses for digital processing of signals in neuroprocessors specialized in summation and multiplication operations. The proof is elaborated by the method of mathematical induction.
Aspects of statistical quality control of products: choice of criteria for uniformity of dispersions
Authors: Faddeenkov A.V. , Landman L.A.
Published: November 2019

Analysis and data processing methods allowing to identify nature of the obtained data and their interrelation quickly and accurately are widely demanded now. To identify the relationship between input and output variables, a researcher faces regression analysis tasks, in particular, the estimation of unknown parameters of regression models. In this case application of classical methods is limited by a number of assumptions, in particular, distribution heterogeneity on the measurement region. Using of various stable, nonparametric and adaptive estimation methods in the presence of heterogeneity in the random errors distribution has not been sufficiently studied on the measurement region, therefore the isolation of homogeneous sub-regions in the general heterogeneity measurement region could help to solve the problem of parameter estimation. The criteria for testing homogeneity hypotheses are very often used in various applications of the problems of statistical analysis. In this case we can talk about testing distribution homogeneity hypotheses corresponding to the samples being analyzed or about mean homogeneity or about variances homogeneity. The aim of the study is to investigate the power of parametric and nonparametric criteria under various competing hypotheses.

Authors: Grif M G , Lukoyanychev A V
Published: November 2019

The article is devoted to the integral system of sign language training. The operation modes of the system based on 3D computer avatar are considered. The user’s feedback using the system is carried out in the test mode using a standard webcam. The user must demonstrate the word or dactyl specified by the system. The problem of gesture localization in the user test mode is considered. The algorithm for the rapid clustering of human hand gestures in a video sequence is proposed. The background removal is based on finding of the inter-element difference for the frames of a video sequence, the selection of the key frames and calculating difference frames. The use of the modified histogram method allows localizing the gesture. The experimental results show the stable operation of this algorithm in different light conditions. This approach allows using developed system both on stationary computers and on mobile devices.
Trainable wavelet-like transform for feature extraction to audio classification
Authors: Ilyashenko I D , Nasretdinov R S , Filin Y A , Lependin A A
Published: November 2019

A method of learning optimal orthonormal filters for feature extraction from 1-D signal based on learning wavelet-like transform was proposed. Filters had been learned by using backpropagation simultaneously with neural network, which was used as a classifier. Orthonormality of filters during the learning process was provided by several quadratic regularization terms that follow from the orthogonality of the scaling functions. The proposed method was evaluated on the environmental sound classification task. We used the trainable wavelet-like transform and wavelet transform with different bases as feature extraction methods with fixed architecture of the neural network. The proposed method obtained the best results. The spectrum characteristics of learned filters of wavelet-like transform were compared with the corresponding characteristics of reverse biorthogonal wavelet basis rbior1.5 that obtained the closest accuracy results.

During the filming by a high-speed video camera, the images of a particle flux moving in a plasma jet during the spraying of powder coatings on machine parts are recorded. The distributions of key physical parameters of particles in the flux cross sections of the plasma jet with the help of algorithms of the filtering and selection of the particle tracks from the images are computed. The distribution of the particle velocities along the jet axis was computed. The processing of the image stream with a small frame exposition time allowed determining the particle bulk density distribution along the plasma jet axis. As a result of images processing for cross section at the end of the flux the dependence of differential density distribution of particles vs. orientation angle of their tracks directions relative to the flux axis has been obtained.
SDC-method of large deviations analysis for nonlinear system
Authors: Kabanov A A , Dubovik S A
Published: November 2019

The paper presents a new method of large deviations analysis for nonlinear systems in the form of state-dependent coefficients. The large deviations of the controlled process from some regular state is the basis of forecasting of the critical situation. The forecasting problem is reduced to the Lagrange-Pontryagin optimal control problem. The presented approach to state-dependent coefficients for the solution of Lagrange-Pontryagin problem is different from the approach used before for linear cases in the fact that it uses a control in the form of feedback instead of programmable control. This eliminates the need to calculate the boundary value in the final time point for the conjugate variable, which is the most time-consuming task in nonlinear cases. An example of using the presented approach to the problem of vessel tilting prediction is considered.

Published: November 2019

The article deals with the problem of segmentation of digital images, which is one of the main tasks in the field of digital image processing (IP) and computer vision. To solve this problem, an algorithm was proposed based on the use of a concept based on the theory of fuzzy sets. The main idea of the proposed algorithm is the formation of subsets of interconnected pixels based on the fuzzy-to-mean method. A distinctive feature of the proposed algorithm is the definition of a set of features that define areas with similar characteristics in the space of the characteristic features of the analyzed image. The proposed segmentation algorithm (SA) consists of two stages: 1) the formation of characteristic features for all channels of the base color; 2) clustering of image elements. The practical significance of the obtained results lies in the fact that the developed models of algorithms can be used in various applied problems, where the classification of objects represented as images is provided. To test the efficiency of the developed algorithm, experimental studies were carried out in solving a number of applied problems related to color image segmentation, in particular, license plate recognition problems.
Time series forecasting method based on genetic algorithm for predicting the conditions of technical systems
Authors: Kureychick V M , Kaplunov T G
Published: November 2019

The pragmatic aim of this paper is to provide a genetic algorithm for predicting the technical systems state. The research novelty is to represent the genuine approach to forecast the technical systems states. The given approach implies finding future values by extrapolating current observation results. Forecast can be considered as a diagnostic control at zero-time extrapolation, or as a general case of diagnosis. The developed genetic algorithm is based on the classical representation of genetic algorithms with the changes required for forecasting. So, a function that validates alternative solutions outlaying from the geometric representation of the average values of the time series plot is exploited as a fitness function. The method based on the use of Shewhart process-behavior charts is also applied to exclude failures of the sensor collecting measured data and to control the mutation. The algorithm performs a prediction for one time interval ahead for processes that are not affected by external factors or processes, or the influence of external factors on which is not significant within one time interval. Our experiment confirmed the efficiency of the suggested algorithm. It resulted in obtaining a predictive solution.

Model, algorithm and computer application for automated selection of varieties and hybrids of grain crops
Authors: Pykhtin A I , Gostev A V
Published: November 2019

Under the conditions of modern high-tech agricultural production, there is a need to develop tools contributing to the scientifically based selection of adaptive varieties and hybrids, considering agrotechnological and soil-climatic features specific for each individual agricultural system. Their development and further implementation in agriculture will contribute to stable and profitable yields of grain crops. Solving this problem, issues related to the definition of criteria that accurately describe the characteristics of the conditions and the degree of their impact on cultivated varieties and hybrids of grain crops are of great importance. The process of cultivar changing due to the changes of climatic, environmental, economic and other conditions is quite common in agriculture and therefore, there is an obvious need of agricultural producers for development of such software. As a result of the research work, a concise mathematical model, an algorithm, a database structure and software were developed to enable obtaining a list of most appropriate varieties/hybrids of main grain crops for the conditions of the European part of the Russian Federation on the basis of user-defined parameters (depending on the selected grain crop). The software was designed in the form of a Web-application accessible from any device connected to the Internet, and the program interfaces were fitted for personal computers, tablet devices and smartphones. The application allows flexible configuration to add new crops, varieties (hybrids) and parameters without changing the source code of the program modules.

Software used to digitize manufacturing operations should provide high degree of reliability, since its failure may cause downtime or disruption of the production process and, as a result, financial losses. One of the approaches to improve software reliability is N-version programming where data processing is performed by different functionally equivalent software components which source code can be written in various programming languages with a number of distinguishing syntactic properties. This paper presents an abstract device for recognizing multi-syntax programming languages. The synthesized device can be used for the development of language translators for N-version software systems.

Published: November 2019

One of the important tasks of the modern stage of development of the shipbuilding industry is the creation of an information model of the vessel and its systems using CAD, PDM, PM, PLM and ERP automated design systems for pre-production. The information model of the vessel and its systems is the most important step in the presentation of data about the ship in digital form during the design and preparation of its construction. Due to the fact that in the Russian shipbuilding industry there is still no common understanding of what the “ship information model” is, according to the authors, it is required to disclose this concept and determine the need to create and use the ship information model at all stages of the ship’s life cycle. The article provides a brief overview of computer-aided design systems used at enterprises in the shipbuilding industry, shows the advantages of using the ship’s information model over paper documentation, lists obstacles to the development of the ship’s information model as an optimization basis at all stages of the ship’s life cycle when all participants in the cooperation interact.
