Authors: Hsu Hao-Teng , Shyu Kuo-Kai , Lee Po-Lei
Published: June 2022

We have developed multi-channel dry-electrode electroencephalography (EEG) system to implement a brain computer interface (BCI) and discriminate four-class motor imagery signals. The EEG channels recorded from Fz, F3, F4, C3, Cz, C4, P3, and P4 positions, according to the international 10‒20 EEG system, were acquired and wirelessly transmitted to a personal computer. Five subjects were recruited to perform right hand, left hand, right foot, and left foot imagery movements with 60 trials in each movement type. EEG data were segmented into epochs from 0 to 8 s and anchored to time points of imagery movement cues. The segmented EEG epochs were pre-processed using the Morlet wavelet. A long short-term memory (LSTM) neural network with 64 LSTM cells was constructed to discriminate EEG signals recorded from different imagery movements. Among total EEG epochs, 80% were randomly chosen as training data and the rest 20% were used as validation data. The detection accuracy reached 89%.

Published: June 2022

The effects of heavy ion irradiation on the electrical response of HfO2-based ferroelectric capacitors have been studied. All the hysteresis loops measured from the irradiated samples shifted toward the positive voltage. The remanent polarization and relative permittivity of the capacitors decrease with increasing ion fluence. The leakage current exhibit negligible change after irradiation. The main reason causing the phenomena is swift heavy ions (SHIs) induced the pinning of domain walls, attributed to the phase transition. This work provides the possible physical mechanisms of SHIs irradiation on HfO2-based ferroelectrics, which is of significance for the space application of HfO2-based ferroelectric random access memory.

Published: June 2022

In order to evaluate the phenomena in a contiguous interface between a wet polyvinyl alcohol (PVA) sponge and various wafers during a chemical mechanical polishing cleaning process, the torques of a rolling wet PVA sponge were measured when it was pressed against various materials. In particular, we sought to determine how the torques between two materials were affected by surface free energy, which is a surface condition parameter consisting of hydrogen bonding component and dispersive component. The results of our investigation suggest that increasing the rotational speed of a wet PVA sponge decreases some of the torques generated due to hydrogen bonding component interactions.
High channel mobility of 3C-SiC n-MOSFETs with gate stacks formed at low temperature—the importance of Coulomb scattering suppression
Authors: Yamamoto Keisuke , Wang Dong , Nakashima Hiroshi , Hishiki Shigeomi , Uratani Hiroki , Sakaida Yoshiki , Kawamura Keisuke
Published: June 2022

We fabricated n-channel MOSFETs with various gate dielectrics on (111) oriented 3C-SiC/Si. Fabricated MOSFETs operated as inversion mode devices successfully. The MOSFET with sputter-deposited SiO2/plasma oxidized interlayer showed a high peak field-effect mobility of 131 cm2 V−1 s−1. The gate stack can be formed at a low temperature of 400 °C, which means the process is absolved from high-temperature thermal oxidation for a gate stack. The detailed analysis of charges and traps in the gate stacks clarified that Coulomb scattering is well-suppressed in the inversion channel. These results will be the first step for a high-performance 3C-SiC application, including on-chip hetero-integrated electronic devices.
Influence of hydrochemical parameters on the species diversity of the fish fauna of small rivers in the Saratov region
Authors: Kiyashko V. V. , Kiyashko I. A.
Published: June 2022

The results of our monitoring of small rivers in the Saratov region (tributaries of the Volgograd reservoir) are presented. Hydrochemical and organoleptic analysis of water quality was carried out. The species composition of the ichthyofauna of water bodies has been investigated. Factors affecting the chemical composition and organoleptic parameters of small river water are shown, namely: the degree of economic development of the river valley and geomorphological characteristics. An increase in the degree of pollution (eutrophication) of the small tributaries of the Volgograd reservoir negatively affects the ichthyofauna of the reservoirs by reducing the numbers of the most water-demanding fish species (stenobionts) with their subsequent disappearance and, as a result, the reservoir passes from one fishery type to another one.

The influence of the global climate warming on the population dynamics of the small ground squirrel at the border of its range in the northern desert zone on the territory of the Ilmenno-Prideltovy landscape area of the Caspian lowland in 1945–2019 is considered. Data on the numbers of small ground squirrels and the average monthly air temperature in January–February at the Astrakhan weather stations for the last 75 years have been analyzed and statistically processed. It is emphasized that the abundance dynamics of the species is determined by a whole complex of natural and anthropogenic factors. At the same time, in desert conditions, the distribution of air temperature and precipitation by seasons and years is limiting for the small ground squirrel. The January–February temperature effect provoking the awakening of the small ground squirrel from hibernation is analyzed. The high January temperature, followed by the February cooling, led to the mass death of animals, which would subsequently negatively affect the phenology of the main phenomena in the life of this monoestral species, disrupt the population structure and lead to a decrease in the numbers of animals. Against the background of the low January air temperatures, the awakening of the small gopher took place in February–March, and the higher February temperatures provided optimal conditions for a simultaneous exit from hibernation and participation in the reproduction of all sex and age groups of small gophers. Such a combination of January and February air temperatures took place during 1960–1979, which contributed to the growth and preservation of a relatively high level of the species' abundance. The high temperatures of the 1980–2009 winter months provoked the early release of the animals from hibernation: the numbers of ground squirrels decreased and kept at a low level. Against the background of decreases temperatures of the 2010–2019 winter periods, the effect of stabilization of the small ground squirrel population and some increase in the density of the species was observed.

Authors: Ajisebiola Babafemi S.
Published: June 2022

Background: Moringa oleifera is a medicinal plant with numerous pharmacological actions against many diseases, including snakebite. To date, there is no report on the anti-venom effects of M. oleifera leaf against Causus maculatus envenomation. Thus, the impact of M. oleifera leaves were investigated against the toxic effects of C. maculatus venom.
Methods: In this study, the ethanol leaf extract of M. oleifera was partitioned using n-hexane and ethyl acetate thereafter, the efficacies of solvent fractions on C. maculatus-envenomed rats and some biological activities of the venom were investigated. The lethal dose (LD50) of the venom was determined in rats. Subsequently, the antivenom effects of solvent fractions of M. oleifera extract against envenoming and some biological activities of C. maculatus venom were evaluated.
Results: The venom’s acute toxicity (LD50) was estimated to be 2.9 mg/kg-1. In a dose-dependent manner, M. oleifera inhibited heamolytic and heamorrhagic activities of Causus maculatus venom. Also, acute anemia and thrombocytopenia induced by the venom were reversed after treatment with ethanol and n-hexane solvent fractions of M. oleifera extract. Furthermore, M. oleifera ameliorated various histopathological defects observed in tissues of vital organs of envenomed treated rats.
Conclusion: Results demonstrated that M. oleifera leaves could serve as an anti-snake agent against toxicities induced by C. maculatus venom

Authors: Osinupebi Olubunmi A.
Published: June 2022

Background: Health-care workers (HCWs) are often exposed to potentially infectious body fluids-carrying Hepatitis B virus (HBV) from their workplaces. Typically, most asymptomatic HBV carriers-status may remain unnoticed for decades, despite a few percentages of them with vaccination history. In this study, we aimed at investigating asymptomatic carriage of HBV and its associated risk factors among co-health workers ultimately impacting on patients.
Methods: Venous blood samples and demographic data were obtained from a cross sectional survey of HCWs categories working in OOUTH, a referral teaching hospital and other selected health facilities in Ogun state. Immuno-chromatographic discs and Enzyme Linked Immuno-Sorbent assay (ELISA) techniques were adopted for
the determination and confirmation of the presence of HBsAg, anti-HBs and total anti-HBc in sera. A structured questionnaire was used for obtaining demographic data which were analyzed by regression analytical technique.
Results: About 11.44% (43) of the 376 healthcare workers (HCWs), were infected with HBV. The serological marker of viral particles identified in this positive study population included Hepatitis B envelope antigen (53.49%), Hepatitis Core antigen (13.15%), Hepatitis B surface antibodies (3.99%); and Hepatitis B core antibodies (0.80%). A significant association existed between risk factors such as recapping of used needles and carriage of HBV among the HCWs (p-value =0.017).
Conclusion: The carriage rate (11.44%) of HBV among HCWs in Ogun state referral health facilities as against the 8% set standard by W.H.O. in 2009, depict the associated risk factors of asymptomatic carriage, pathogenesis and dissemination in and outside of the health facilities.

Authors: Dauda Oluwadamilare G.
Published: June 2022

Background: Haemoparasites and intestinal helminths are significant constraints to livestock production resulting in substantial economic loss, and some helminth parasites of cattle are of serious public health concern. This study investigated the prevalence of haemoparasites and polyparasitism of intestinal helminths amongst cattle slaughtered in two major abattoirs of Abeokuta metropolis and their implications for public health.
Methods: Blood and faecal samples were randomly collected from 256 cattle less than two and greater than two years of age. Blood samples were screened for Packed Cell Volume (PCV) using the haematocrit centrifuge technique and parasites were detected by microscopy using a wet mount, buffy coat and stained thin smear. Helminth eggs and oocysts were detected using centrifugal sedimentation and centrifugal faecal flotation method.
Results: Results showed prevalence for Trypanosoma spp., Babesia spp., Anaplasma spp. and Theileria spp. to be 8.3%, 27.34%, 20.7% and 0.39%, respectively. For intestinal parasites, the prevalence for Strongyle eggs is 73.82%, Neoascaris vitulorum 0.8%, Fasciola spp. 10.15%, Moniezia spp. 4.3%, Eimeria oocyst 35.94% and Cryptosporidium oocyst was 1.17%. The total prevalence of coinfection of haemoparasite and intestinal helminths was 42.6%. Breed-specific prevalence for co-infection of haemoparasites and intestinal parasites showed 55.96%, 37.6% and 6.4% for White Fulani, Red Bororo and Sokoto Gudali, respectively which was statistically insignificant (p > 0.05). With regards to sex, females had a higher prevalence of 92 (84.4%) of coinfection of haemoparasites and intestinal helminths than males 17 (15.6%), which was statistically significant (p<0.05).
Conclusion: This study revealed a high prevalence of haemoparasites and intestinal parasites in cattle slaughtered in Abeokuta, Nigeria. Therefore, the study recommends strict compliance with meat inspection at abattoirs and the need for immediate operationalisation and implementation of a sustainable Preventive One Health intervention to mitigate against the outbreak of zoonoses in Abeokuta.

Authors: Liu Gui
Published: June 2022

MIMO antenna for 5G applications

A quad-element multiple-input multiple-output (MIMO) antenna operating in 3.5 GHz (3.4GHz-3.6GHz) and 4.9GHz (4.8GHz-4.96GHz) frequency bands for the fifth-generation (5G) smartphone applications is presented. Each single radiating element consists of an L-shaped strip and a modified C-shaped strip. To keep enough space for second-, third-and fourth-generation (2G/3G/4G) antennas in a limited space, four antenna elements are printed respectively at four corners of a system board. The total size of the proposed antenna is only 145×75×5mm3. The design steps and the analysis of key parameters of an individual antenna element are derived to demonstrate the design methodology of the proposed antenna. The measured total radiation efficiency is better than 60% at both the operating frequency bands. The measured isolation is better than 16 dB and the calculated envelope correlation coefficient (ECC) is smaller than 0.02. The measured results demonstrate that the proposed MIMO antenna is a good alternative for sub-6 GHz 5G smartphone applications.
KT-Bi-GRU: Student Performance Prediction with a Recurrent Knowledge Tracing Neural Network
Authors: Delianidi Marina , Diamantaras Kostas
Published: June 2022

The work in this paper is an extended research of our previous work: M. Delianidi, K. Diamantaras, G. Chrysogonidis, and V. Nikiforidis,“Student performance prediction using dynamic neural models,” in Fourteenth International Conference on Educational Data Mining (EDM 2021), 2021, pp. 46–54. In both works we study the task of predicting a student's performance in a series of questions based, at each step, on the answers he/she has given on the previous questions. We propose a recurrent neural network approach where the dynamic part of the model is a Bidirectional GRU layer. In this work, we differentiate the model architecture from the earlier paper by imposing that the dynamic part is based exclusively on the history of previous question/answers, not including the current question. Then, the subsequent classification part is fed by the output of the dynamic part and the current question. In this way, the first part estimates the student's knowledge state and represents it with a dynamically generated vector considering only the student's previous questions and responses. We call this part the “Knowledge State Representation subnet''. Using this representation, the following “Tracing subnet'' which is a static multi-layer classifier can predict the correctness of the answer to any following question. Therefore, this architecture is suitable not only for described prediction task but also for recommendation tasks which were not possible with the previous architecture. In addition, in this work, we also study the effectiveness of our models against each other, as well as against the previous state-of-the-art models on seven datasets including a new multi-skills dataset derived from the NeurIPS 2020 education challenge. Both our models compare favorably against the state-of-the-art methods in almost all datasets, while the newly proposed architecture achieves very similar results compared to our earlier model in most cases except for two cases, including the multi-skill “NeurIPS-2020-small'' dataset, where it achieves considerably better results.
Harmonic Current Emission Estimation of Modular Multilevel Converters in MV Charging Stations
Authors: Gong Sicheng , Cuk Vladimir , Cobben Sjef
Published: June 2022

This paper proposes a novel framework for modular multilevel converter (MMC) current harmonic emission estimation from medium voltage (MV) charging stations. The framework is enlightened by wave decomposition, exploiting an analytical derivation of the emission, without a time-domain model. Accordingly, voltage harmonic distribution in grids can be estimated with a frequency-domain model, using the estimated voltage-dependent current emission in the iterations. Compared to conventional time-domain simulation, such method not only enables analytical harmonic estimation integrated with a large load-flow model, but also benefits from the potential of distributed computation. A 10.5kV grid-tied single-phase half-bridge MMC simulation case on PLECS has been implemented and investigated for comparison. Corresponding results revealed that the estimated harmonic series kept the absolute average difference to the PLECS model lower than 0.02% and  a correlation ratio higher than 99.79% with the simulated ones. The effectiveness of the proposed estimation framework is successfully verified.

Authors: Susanto Natalie Sandra , Prasetyaningsih Aniek , Madyaningrana Kukuh
Published: June 2022

Skin disease is one of the most common diseases in tropical countries such as Indonesia, which might be caused by infection of pathogens like Staphylococcus aureus and Pseudomonas aeruginosa. Red algae Gracilaria sp. originated from Wediombo Beach, Yogyakarta, Indonesia has not been widely used for medicinal purpose, especially as an antimicrobial for skin diseases in human. Therefore, this research aimed to study about the potency of local Gracilaria sp. extract as an antibacterial against skin disease pathogen. Red algae extraction was carried out using maceration method in ethanol solvent. Identification of phytochemical groups was determined using basic biochemistry analysis and Thin Layer Chromatography (TLC), while active phytochemical compounds were identified using Gas Chromatography-Mass Spectrophotometry (GC-MS). Antibacterial tests were performed by minimum inhibition concentration (MIC) using MTT indicator and inhibition assay using paper disc method. Alkaloids and saponins were identified in phytochemical based on biochemical tests. Compound separation by TLC using chloroform and methanol solvents with a ratio of 90:10 resulted in seven color spots with ninhydrin spray and six color spots with anisaldehyde spray. The GC-MS results showed that there were 38 compounds identified in the crude extract, which 8 of these 38 compounds are known to have anti-bacterial activity. Anti-bacterial assay of Gracilaria sp. extract on concentration of 100% showed medium strength to inhibit Staphylococcus aureus and strong strength to inhibit Pseudomonas aeruginosa. Crude extract of local Gracilaria sp. is potential to be used as antimicrobials against Staphylococcus aureus and Pseudomonas aeruginosa common agents for skin disease.

Published: June 2022

The high strength of organic photovoltaic cells lies in the variety of organic ingredients that can be built and synthesized for absorbers, receptors, and boundaries. Still, we need further development for better performance and existence of the system. In this research study, electrical simulations of different active layer materials have been performed via GPVDM software to observe the outcomes of a solar cell. Furthermore, the electrical simulation has been performed at different active layer thicknesses from 50 nm to 300 nm with active material P3HT: PC70BM. We analyzed by performing simulations with different parameters to observe the best parameters for organic solar cell performance. We observed that absorber layer thickness of 200 nm, hole transport layer of Cu2O, pair of ITO/Al electrodes, and exponential DOS exhibit superior outcomes. At the same time, the highest power conversion efficiency was reported with active layer PTB7:PCB70BM due to its efficient optical properties. Organic solar cells are versatile and gaining popularity for a broad range of applications to keep up with the increasing energy demand and comparatively lower energy payback time.
H-BRIDGE THIRTEEN LEVEL INVERTER USING REDUCED NUMBER OF SWITCHES FOR INDUSTRIAL APPLICATIONS
Authors: S.Vijayabaskar  , D.Subramani  , K.Manoj  , P.Vishnuprasanth
Published: June 2022

The single phase cascaded H-bridge multilevel inverter (Thirteen level) is designed for industrial applications and has a decreased number of switches. Cascaded Multilevel Inverters are widely used in the electric utility industry and for industrial motors. When these inverters are used directly for industrial drives, the THD contents in the output voltage of the inverters are extremely important since the performance of the drive is highly dependent on the quality of the voltage applied to it. The symmetric and asymmetric inverters are two forms of cascaded H-bridge inverters that use input voltage from various sources. Only one H-bridge (with four switches) and three additional switches make up the proposed asymmetric cascaded H-bridge topology, which has a total of seven switches for a 13-level output voltage. Drives and renewable energy applications benefit from the new topology. For different layers of multilevel inverters, THD is determined by modulation index. The THD is decreased to 9.18% using the PWM approach, and the THD is analysed using MATLAB/SIMULINK. The proposed topology has been tested utilising a single phase 13 level inverter and a DSPIC 30F2010 controller.

Compared to the dual-active-bridge converter, the Double-bridge arrangement thunderous converter (DBSRC) can extend delicate exchanging run. To encourage broaden the soft-switching extend and progress the circuit execution, a modern DBSRC with double tank based on DBSRC is proposed in this paper. This modern converter highlights two thunderous tanks and a tapped transformer, and it can perform superior than the DBSRC by optimized tap coefficient x of the tapped transformer. Its operation guideline, voltage pick up, the soft-switching characteristics, and yield control are analyzed in detail, and compared with the DBSRC. Comes about appear that the pro-posed dual-tank topology has displayed higher voltage pick up, more extensive soft-switching locale, and bigger yield control than the conventional DBSRC when the tap-coefficient x is chosen sensibly. DC-to-DC bidirectional resounding converter to be utilized for bidirectional control exchange applications particularly battery charging discharging applications in electrical vehicles.
Its similar to an LLC resonant converter, but on the secondary side of the circuit, an additional inductor and capacitor have been added to make the resonant network symmetric for operation in both forward and backward directions. The switches in the inverting step have zero voltage switching (ZVS). Under ZCS, the rectifier diodes on the secondary side also turn off. ZVS and ZCS reduce losses and enable high-frequency operation, resulting in smaller magnetic elements and filter capacitors, lowering size, weight, and volume while enhancing power density.

The article substantiates the role and importance of an integrated accounting system, the need and features of its use by Ukrainian businesses.
The number of business entities by types of economic activity in Ukraine is analyzed, information on trends in their associations is identified, which encourages the need for integrated accounting. It is outlined that the integration of accounting is manifested through the combination of the data from different types of accounting in one accounting system.
The structure of the accounting system for sustainable development according to H. Jobstle is considered, which allows to combine the data from accounting, social and environmental accounting, as a result, the information needs of a wider range of interested users (both internal and external) are met.
The possibility of integration of accounting, depending on the business entity, its type of activity and other factors that affect the content of the information space in accordance with the different needs of users of accounting information is considered. In particular, it was found that owners, managers and management staff (internal users of accounting information) are interested in the integration of financial, management and tax accounting. Consumers of products and services are interested in information that is formed by combining data from accounting, environmental and social accounting and reflects the quality and cost characteristics of such products and services. From the point of view of the Consortium's activity, as an association of enterprises, institutions and organizations, it is expedient to integrate accounting by types of activity: science, educational process and production.
It is established that the integration of accounting for this activity is possible through the formation of the Work Plan of accounts. In this case, the Chart of Accounts is an accounting model that is a part of the technical basis for the formation of accounting information.
Based on the study, the directions of further research on the use of an integrated accounting system by business entities and the reasons for their need are indicated.

Authors: Ribeiro Luma Rossi , Leite Thiago Soares , Cristianini Marcelo
Published: June 2022

Effect of High-Pressure with Temperature (HPP+T) and Thermal Processing (TP) were evaluated on the rheological characteristics of mango pulp. Samples were subjected to an equivalent condition of a 5D (5 log reduction) process for HPP+T (600 MPa/6.3 min at 90 °C) and TP (95 °C/10.5 min) to be compared. Storage-modulus (G') and loss-modulus (G'') were modeled according to the oscillatory frequency using the Power-Law. TP and HPP+T showed G' > G'' at all evaluated times. Both processes did not result in significant increases in the elastic and viscous behavior of the mango pulp. The flow behavior of the mango pulp presented a pseudoplastic characteristic with relevant residual tension. The Herschel-Buckley model was used to model the flow curves fitted well (R2 ≥ 0.99) and both processes increased the consistency index of the mango pulp. HPP+T proved to be a promising technology, which in addition to increasing the consistency of the product uses reduced time and temperature.
