Partial Asymmetry Measures for Square Contingency Tables
Authors: Ishihara Takuma , Yamamoto Kouji , Tahata Kouji , Tomizawa Sadao
Published: September 2022

In square contingency table analysis, we consider a partial measure that represents the degree of departure from symmetry for each of several pairs. It may be useful to pool the values of the measure into a single summary measure of partial asymmetry. We show that the estimator of partial measures is asymptotically mutually independent for a large sample size. The present paper proposes a symmetry measure in the class of weighted averages that is different from previous studies. The proposed measure is an approximation of the measure in the class of weighted averages that has the smallest variance.

Published: September 2022

In the last two decades, academicians have concentrated on the nanofluid squeezing flow between parallel plates. The increasing energy demands and their applications have seen the focus shifted to the hybrid nanofluid flows, but so much is still left to be investigated. This analysis is executed to explore the symmetry of the MHD squeezing nanofluid (MoS2/H2O) flow and the hybrid nanofluid (MoS2–SiO2/H2O–C2H6O2) flow between the parallel plates and their heat transport property. The heat transport phenomenon is analyzed with the magnetic field, thermal radiation, heat source/sink, suction/injection effect, and porous medium. In the present model, the plate situated above is in the movement towards the lower plate, and the latter is stretching with a linear velocity. The prevailing PDEs depicting the modeled problem with the aforementioned effects are transformed via similarity transformations and solved via the “bvp4c” function, which is an inbuilt function in MATLAB software. The control of the factors on the fields of velocity and temperature, heat transfer rate, velocity boundary layer patterns, and streamlines is investigated. The solution profiles are visually shown and explained. Furthermore, the Nusselt number at the bottom plate is larger for the (MoS2–SiO2/H2O–C2H6O2) hybrid nanofluid than for the (MoS2/H2O) nanofluid flow. In the presence of suction/injection, the streamlines appear to be denser. In addition, the magnetic field has a thinning consequence on the velocity boundary layer region. The results of this study apply to several thermal systems, engineering, and industrial processes, which utilize nanofluid and hybrid nanofluid for cooling and heating processes.
Realization of Quantum Swap Gate and Generation of Entangled Coherent States
Authors: Zhang Ziqiu , Jiang Xi , Tang Shiqing
Published: September 2022

The cross fusion of quantum mechanics and information science forms quantum information science. Quantum logic gates and quantum entanglement are very important building blocks in quantum information processing. In this paper, we propose one-step schemes for realizing quantum swap gates and generating two-mode entangled coherent states via circuit QED. In our scheme, due to the adiabatic elimination of the excited state of the qutrit under the condition of large detuning, the decoherence of the spontaneous emission of the qutrit can be ignored. The fidelity of the quantum swap gate remains at a very high level. In addition, we also explore the nonclassical properties of two-mode entangled coherent states prepared in our scheme by addressing the second-order correlation function and intermodal squeezing. In particular, two classes of entangled coherent states demonstrate distinct entanglement and nonclassical behavior.

Published: September 2022

Zearalenone (ZEN) is one of the mycotoxins that pose high risks for human and animal health, as well as food safety. However, the regulators involved in ZEN cellular toxicity remain largely unknown. Herein, we showed that cell viability of porcine intestinal epithelial cells (IPEC-J2) tended to decrease with increasing doses of ZEN by the cell counting kit-8 assay. Expression of the ISLR2 (immunoglobulin superfamily containing leucine-rich repeat 2) gene in IPEC-J2 cells was significantly downregulated upon ZEN exposure. Furthermore, we found the dose–effect of ZEN on ISLR2 expression. We then overexpressed the ISLR2 gene and observed that overexpression of ISLR2 obviously reduced the effects of ZEN on cell viability, apoptosis rate and oxidative stress level. In addition, ISLR2 overexpression significantly decreased the expression of TNF-α and IFN-α induced by ZEN. Our findings revealed the effects of ZEN on the ISLR2 gene expression and indicated the ISLR2 gene as a novel regulator of ZEN-induced cytotoxicity, which provides potential molecular targets against ZEN toxicity.

Published: September 2022

Mitochondria hold redox homeostasis and energy metabolism as a crucial factor during oocyte maturation, while the exposure of estrogenic mycotoxin zearalenone causes developmental incapacity in porcine oocyte. This study aimed to reveal a potential resistance of phytoalexin resveratrol against zearalenone during porcine oocyte maturation and whether its mechanism was related with PTEN-induced kinase 1 (PINK1)/Parkin-mediated mitophagy. Porcine oocytes were exposed to 20 μM zearalenone with or without 2 μM resveratrol during in vitro maturation. As for the results, zearalenone impaired ultrastructure of mitochondria, causing mitochondrial depolarization, oxidative stress, apoptosis and embryonic developmental incapacity, in which mitophagy was induced in response to mitochondrial dysfunction. Phytoalexin resveratrol enhanced mitophagy through PINK1/Parkin in zearalenone-exposed oocytes, manifesting as enhanced mitophagy flux, upregulated PINK1, Parkin, microtubule-associated protein light-chain 3 beta-II (LC3B-II) and downregulated substrates mitofusin 2 (MFN2), voltage-dependent anion channels 1 (VDAC1) and p62 expressions. Resveratrol redressed zearalenone-induced mitochondrial depolarization, oxidative stress and apoptosis, and accelerated mitochondrial DNA copy during maturation, which improved embryonic development. This study offered an antitoxin solution during porcine oocyte maturation and revealed the involvement of PINK1/Parkin-mediated mitophagy, in which resveratrol mitigated zearalenone-induced embryonic developmental incapacity.

Published: September 2022

Uremic metabolites, molecules either produced by the host or from the microbiota population existing in the gastrointestinal tract that gets excreted by the kidneys into urine, have significant effects on both health and disease. Tryptophan-derived catabolites are an important group of bacteria-produced metabolites with an extensive contribution to intestinal health and, eventually, chronic kidney disease (CKD) progression. The end-metabolite, indoxyl sulfate, is a key contributor to the exacerbation of CKD via the induction of an inflammatory state and oxidative stress affecting various organ systems. Contrastingly, other tryptophan catabolites positively contribute to maintaining intestinal homeostasis and preventing intestinal inflammation—activities signaled through nuclear receptors in particular—the aryl hydrocarbon receptor (AhR) and the pregnane X receptor (PXR). This review discusses the origins of these catabolites, their effect on organ systems, and how these can be manipulated therapeutically in the future as a strategy to treat CKD progression and gut inflammation management. Furthermore, the use of biotics (prebiotics, probiotics, synbiotics) as a means to increase the presence of beneficial short-chain fatty acids (SCFAs) to achieve intestinal homeostasis is discussed.

EVOLUTION OF VALUE MOTIVES OF CONSUMPTION IN POST-SOVIET COUNTRIES: THE EXAMPLE OF UKRAINE
Authors: SIDDHARTH SIDDHARTH , SOKHATSKA Olena
Published: September 2022

The paper considers the evolution of household consumption in Ukraine to study the changes in consumer behaviour over time. The purpose of this study is to analyse patterns of consumer behaviour in Ukraine and their historical roots. This will facilitate a better understanding of factors driving consumer behaviour of Ukrainians, help forecast its future changes and develop mechanisms and instruments for Ukrainian companies to manage consumer behaviour. Research results reveal that Soviet consumption habits are still affecting Ukrainian patterns of consumer behaviour. Even younger population that has never experienced the Soviet system is affected by its consumptive patterns to some extent. After the USSR’s collapse, Ukraine started to adopt consumer behaviour patterns from the Western world, first of all the consumerism and its inherent consumer protection, as well as the more recent fight against excessive consumption. At the same time, another global consumption trend – creative consumerism – is being actively adopted by Ukrainians, partly because such forms of behaviour are inherited from Soviet society. Modern technologies along with the COVID-19 crisis effect the patterns of consumer behaviour in Ukraine, primarily through the increasing role of online technologies in consumer decision making, in purchasing and post-purchasing processes.

Grain density control in FePt granular films for heat-assisted magnetic recording media
Authors: Suzuki I. , Takahashi Y. K.
Published: September 2022

To realize high areal density, hard disk drives larger than 4 Tbit in−2, ultrafine FePt grains of less than 5 nm and grain density larger than 24 T in−2 are required. Although there have been many investigations to reduce the grain size of FePt, there are only a few reports on the control of grain density. To increase the grain density, we focused on three aspects of the surface morphology and grain density: nucleation sites on the substrate surface, surface free energy, and lattice mismatch. We achieved 14 T in−2 by maximizing the number of nucleation sites in the FePt-C granular film and found that the surface free energy and lattice mismatch are crucial parameters for controlling the grain density.
Magnetic properties and nanostructure of FePt-TiN granular films deposited with N2 gas addition for heat assisted magnetic recording media
Authors: Tham Kim Kong , Kushibiki Ryosuke , Saito Shin
Published: September 2022

Magnetic properties and nanostructure for FePt-30vol%TiN deposited while flowing N2 gas are investigated. When N2 gas addition of 3%–5% are introduced, compared with that of without N2 gas, reduction in the lattice constant ratio and the unit cell volume, the increase in the degree of order of the granular film are observed. These indicate the segregation of Ti into grain boundaries as the result of the N2 gas addition through nitridization of Ti dissolved in the FePt grains which lead to the enhancement of saturation magnetization, perpendicular magnetic anisotropy, and magnetic anisotropy field of the granular film. Therefore, magnetic decoupling in the FePt-TiN similar to the FePt-BN granular films is promoted by the segregation of nitrides formed by nitridization of metal element solidly soluble in FePt magnetic grains due to nitrogen deficiency.
Copper iodide semiconductor: a non-hygroscopic, bright red-emitting scintillator for X-ray and gamma-ray detection
Authors: Fujimoto Yutaka , Asai Keisuke
Published: September 2022

In this work, the inverse temperature crystallization and scintillation properties of copper iodide (CuI) semiconductors are presented. Single crystal of a γ-CuI is very attractive for X- and gamma-ray detection applications due to its non-hygroscopic and excellent light yield with long-wavelength emission in the red. The grown crystal shows an almost colorless and transparent feature and exhibits a red emission band peaking at 730 nm with a fluorescence quantum efficiency (QE) of 43% under excitation at 416 nm. The photoluminescence (PL) decay time constant was estimated to be approximately 175 ns (20%) and 2507 ns (80%) using an exponential fitting. The X-ray excited scintillation band appeared near the wavelength of 720 nm. The scintillation light yield reached 80000 photons MeV–1 compared with a CsI:Tl commercial scintillator.
Demonstration of in-plane miniband formation in InAs/InAsSb ultrahigh-density quantum dots by analysis of temperature dependence of photoluminescence
Authors: Tatsugi Sho , Miyashita Naoya , Sogabe Tomah , Yamaguchi Koichi
Published: September 2022

Self-assembled InAs/InAsSb ultrahigh-density quantum dots (UHD QDs) were grown on GaAs(001) substrate by molecular beam epitaxy. The QD density was 1 × 1012 cm−2, and an average separation distance between adjacent QD edges was less than 3 nm. The temperature dependence of photoluminescence (PL) minimum energy of UHD QDs was measured and was divided clearly into three temperature regions: (1) fitting to upper Varshni shift at 15–80 K, (2) decreasing from upper Varshni shift from 80–180 K and (3) re-fitting to lower Varshni shift at 180–290 K. The energy difference between upper and lower Varshni curves increased with increasing QD density. This anomalous temperature dependence of PL minimum energy was demonstrated by a simulation model of miniband formation due to electronically strong coupling of adjacent QDs, including the temperature dependence of the homogeneous broadening in the QD.
Weak localization on moiré superlattice in twisted double bilayer graphene
Authors: Kashiwagi Masaki , Taen Toshihiro , Uchida Kazuhito , Watanabe Kenji , Taniguchi Takashi , Osada Toshihito
Published: September 2022

Negative magnetoresistance owing to weak localization (WL) was investigated in twisted double bilayer graphene (TDBG) as a function of the twist angle. The ratio of the intervalley scattering time to the intravalley scattering time, estimated using the WL formula for bilayer graphene, tended to decrease as the twist angle increased. This feature is qualitatively explained by the enhancement of intervalley scattering due to the reduction of the intervalley distance in the moiré Brillouin zone (BZ). This indicates that WL in the TDBG occurs with the reconstructed BZ and originates from the scattering process owing to the disorder in moiré superlattice.

Published: September 2022

The purpose of this work was to determine the origin of pigs (Large White × Landrace) × Maxgro of the final hybrid using mitochondrial DNA markers. As a genetic material used bristles from the auricle of commercial pigs (large white × landrace) × Maxgro. DNA secretion was carried out according to the method of Korinnyi S.M., etc.2005, using Chelex ion exchange resin – 100. For the analysis of the mitochondrial genome, the method of polymorphism of the lengths of restriction fragments amplified in PCR was used (Polymerase chain reaction-restriction fragment of polymorphism – PCR-RFLP). The D-loop of the mitochondrial genome of a pig of 428 pairs is subject to analysis of nucleotide with Tasl recognition sites in positions 15558, 15580, 15616, 15714, 15758). Comparison of inherited on the maternal line restrict fragments in the breed allowed get reliable information about the origin of the experimentally studied sample of pigs of the final hybrid (n=15) from RPE "Globinsky Pig Farm", Globyno, town Poltava region, Ukraine allowed getting reliable information of their origin. Laboratory research was carried out based at the Institute of Pig Breeding and Agricultural Production NAAS in the Laboratory of Genetics. By analyzing nucleotide sequences, one monomorphic site was identified and experimentally investigated in position 15558 p.n. and three polymorphic sites in positions 15580, 15616, 15714, 15758 p.n. for endonuclease TasI (↓AATT). To systematize combinations of mitochondrial DNA restriction fragments, three breed-specific mitochondrial haplotypes were identified in an experimentally studied sample of hybrid pigs (n=15). With its use, mitochondrial haplotypes of pigs of the final hybrid were determined: 4 animals with haplotype C, 6 with haplotype N, and 5 with haplotype O. According to many authors pieces of research, these haplotypes characterize different breeds, namely C – Landrace, N – Large White (Asian type) and O – Landrace. The obtained data on the origin of animals of the final hybrid suggests that two-breed sows were the result of direct (Large White × Landrace) and reciprocal crossing (Landrace × Large White). Genetic examination in the establishment of maternal breeds of hybrid pigs with the help of markers of the mitochondrial genome and the search for a polymorphic area of the X and Y-chromosome to determine the ancestral line has become an urgent issue in continuing our research in modern pig breeding technologies of commercial lines.

Between 2018 and 2020, plant pathogenic bacteria of oleander were examined, and many samples of infected plants were collected from different sites in Hungary. Two non-pigmented Serratia marcescens isolates were identified from oleander by classical and molecular methods. The isolates caused necrotic lesions on oleander leaves. Serratia marcescens is known as an opportunistic mammal or plant pathogen, but non-pathogenic strains are known to be useful biological control agents or plant growth-promoting bacteria. This is the first report of the plant pathogen S. marcescens from oleander, and the first identification of the bacterium in Hungary.

The price of a stock in the market can be influenced by many factors, out of which the sentiment of the investors plays a vital role. Most often, the sentiment of investors depends on the sentiment of the news headlines. Therefore, news headlines also play an important role in the fluctuation of the stock index. This paper uses the combination of Bidirectional Encoder Representations from Transformers (BERT) and Bidirectional Gated Recurrent Unit (BiGRU) algorithms for the prediction of news sentiment scores based on national news headlines and financial news data. Technical indicators like Relative Strength Index (RSI), Exponential Moving Average (EMA), Moving Average Convergence Divergence (MACD), Stochastic Oscillator along with normal stock indicators like ’Date’, ’Open’, ’Close’, ’High’, ’Low’ and ’Volume’ data can be used to predict the short-term momentum of the stock value. This paper uses the BiGRU algorithm to predict the stock index value (a) with technical indicators only and (b) with technical indicators and news sentiment scores. Keeping all the hyperparameters constant, the BiGRU algorithm provided better prediction results when news sentiment scores were added to the dataset along with technical parameters as an input.

Since most people currently live in urban areas and two-thirds of the world's population will live in cities by 2050, understanding urban mobility patterns has become paramount in reducing transport-related greenhouse gas emissions and is critical to effective environmental policies. In this article, we address this issue and propose a theoretical model of daily urban commuting, based on two critical components: the coexistence of cars and public transport and traffic congestion. Combining these components in a hectic-type approach allows us to draw important conclusions about health and transport-related greenhouse gas emissions. We compare our forecasts with empirical data from major cities around the world.

The article considers an approach based on the random cubature method for solving both single and multidimensional singular integral equations, Volterra and Fredholm equations of the 1st kind, for ill-posed problems in the theory of integral equations, etc. A variant of the quasi-Monte Carlo method is studied. The integral in an integral equation is approximated using the traditional Monte Carlo method for calculating integrals. Multidimensional interpolation is applied on an arbitrary set of points. Examples of applying the method to a one-dimensional integral equation with a smooth kernel using both random and low-dispersed pseudo-random nodes are considered. A multidimensional linear integral equation with a polynomial kernel and a multidimensional nonlinear problem – the Hammerstein integral equation – are solved using the Newton method. The existence of several solutions is shown. Multidimensional integral equations of the first kind and their solution using regularization are considered. The Monte Carlo and quasi-Monte Carlo methods have not been used to solve such problems in the studied literature. The Lavrentiev regularization method was used, as well as random and pseudo-random nodes obtained using the Halton sequence. The problem of eigenvalues is solved. It is established that one of the best methods considered is the Leverrier-Faddeev method. The results of solving the problem for a different number of quadrature nodes are presented in the table. An approach based on parametric regularization of the core, an interpolation-projection method, and averaged adaptive densities are studied. The considered methods can be successfully applied in solving spatial boundary value problems for areas of complex shape. These approaches allow us to expand the range of problems in the theory of integral equations solved by Monte Carlo and quasi-Monte Carlo methods, since there are no restrictions on the value of the norm of the integral operator. A series of examples demonstrating the effectiveness of the method under study is considered.

The paper discusses a method for recovering missing samples of an analog signal during transmission over communication channels in applications of the Internet of Things. The aim of the work is to obtain a mathematical description of the procedure for restoring the values of the signal samples from the output of the analog sensor on the receiving side, which were not transmitted in order to reduce the load on data transmission channels. The procedure is based on the well-known principles of adaptive signal processing, based on the dynamic determination of the parameters of digital filters based on the assessment of the least-mean-square (LMS) deviation of the signal passing through the filter from a reference signal obtained in one way or another. A feature of the proposed method is the solution of the inverse problem of restoring the samples of the original signal with the known parameters of the filter and the reference signal. In this work, the problem of skipping and restoring samples of a discrete signal is formulated, an expression is obtained for the objective function of the method for restoring missing discrete samples, as well as an expression for iterative restoration by Newton's method of the values of the samples of the original analog signal on the receiving side, which were not transmitted via the data transmission channel. The conditions for the applicability of the method are established, which consist in the a priori known parameters of the reference signal and the digital filter, which are determined in advance from the known characteristics of the original signal. Filtration and transmission of electrocardiogram signals through communication channels, for which an electrocardiogram can be obtained as a reference form, as the norm for healthy patients, is considered as a problem for the solution of which the proposed method is applicable. The practical significance of the proposed method lies in the organization of distributed computing for IoT systems, for which it is critically important to ensure energy savings of an autonomous power source for sensors and reduce the load on data transmission channels.

Recently, with the development of technologies such as augmented reality and unmanned vehicles that receive information about the environment using video cameras, there is a need for fast and accurate depth assessment in images. This problem is relevant, and has led to in-depth research in this area. This article discusses the fundamental principles of local and global stereo image matching algorithms. The operation of the Semi-Global Block Matching algorithm is described in more detail. The essence of the algorithm is to perform line optimization in multiple directions and calculate the aggregated costs by summing the costs of reaching a pixel with an inequality in each direction. The number of directions affects the execution time of the algorithm, and while 16 directions usually provide good quality, a smaller number can be used to achieve faster execution. A typical implementation of the algorithm in 8 directions can calculate the cost in two passes: the forward pass accumulates the cost on the left, the top-left, top and top-right, and the reverse pass accumulates the cost on the right, bottom. right, bottom, and bottom left. Its implementation is also affected by transferring the calculation of the depth map to a graphics processor (GPU) to speed up processing. The results of the construction of the depth map, as well as the dependence of the time of the algorithm on the size of the input images are shown.

The article deals with the solution of a timely and relevant scientific and technical problem of modeling the data transmission network of a system for monitoring the state of critical state facilities. The need to develop a new model of such a data transmission network is due to the introduction of means of dynamic multimodal authentication of the legitimacy and deviance of the person of critical objects. Such authentication tools for the data transmission network become new sources of incoming load with special properties. For highquality performance of the functions of monitoring a critical object, the article suggests a constructive approach to the development of a model of a heterogeneous packet-switched data transmission network, to which not only messages of traditional communication services, but also messages in a multimodal representation circulate. The protocol data blocks of multi-channel messages are small in size, but they must be transmitted to the management body of a critical object with high security re-quirements. In this regard, the object of modeling – a data transmission network with packet communication is represented as a queuing system with absolute priority and channel resource reservation. This approach avoids replacing more resource-intensive messages (traditional communication services) with less resource-intensive ones (messages in a multimodal representation) while meeting the quality of service requirements of both types of load. As a result of the simulation, expressions are obtained for calculating the quality of service indicators for incoming requests for messages of traditional communication services and messages in a multimodal representation. The proposed model, together with the existing models of queuing systems, will allow solving computational and research tasks to find rational design strategies for building data transmission networks with packet switching for monitoring critical state facilities.

The explosive growth of data arrays, both in the number of records and in attributes, has triggered the development of a number of platforms for handling big data (Amazon Web Services, Google, IBM, Infoworks, Oracle, etc.), as well as parallel algorithms for data analysis (classification, clustering, associative rules). This, in turn, has prompted the use of dimensionality reduction techniques. Feature selection, as a data preprocessing strategy, has proven to be effective and efficient in preparing data (especially high-dimensional data) for various data collection and machine learning tasks. Dimensionality reduction is not only useful for speeding up algorithm execution, but can also help in the final classification/clustering accuracy. Too noisy or even erroneous input data often results in less than desirable algorithm performance. Removing uninformative or low-informative columns of data can actually help the algorithm find more general areas and classification rules and generally achieve better performance. This article discusses commonly used data dimensionality reduction methods and their classification. Data transformation consists of two steps: feature generation and feature selection. A dis tinction is made between scalar feature selection and vector methods (wrapper methods, filtering methods, embedded methods and hybrid methods). Each method has its own advantages and disadvantages, which are outlined in the article. It describes the application of one of the most effective methods of dimensionality reduction - the method of correspondence analysis for CSE-CIC-IDS2018 dataset. The effectiveness of this method in the tasks of dimensionality reduction of the specified dataset in the detection of computer attacks is checked.
