Published: September 2019

O estudo teve como objetivo avaliar três métodos de aprendizagem de máquina (árvore de decisão-J48, random forest e redes neurais artificias), na modelagem da distribuição de dez espécies arbóreas mais abundantes em uma sub-bacia do rio São Francisco (MG). Utilizaram-se dados provenientes do Inventário Florestal de Minas, com total de 77 fragmentos amostrados e 2.234 parcelas, nas quais foram computadas a presença/ausência de cada espécie. Empregaram-se 12 variáveis ambientais categóricas procedentes do Zoneamento Ecológico Econômico de Minas Gerais (ZEE/MG), além de variáveis relacionadas ao balanço hídrico do solo (evapotranspiração atual e potencial, aridez e índice alpha). A parametrização dos três algoritmos para as dez espécies selecionadas foi feita com o auxílio do algoritmo cv parameter do software WEKA. Os resultados mostram que os algoritmos testados apresentaram desempenhos estatisticamente iguais em 60% das espécies arbóreas. Os algoritmos random forest e multilayer perceptron foram estatisticamente iguais para a espécie Eugenia dysenterica, sendo superiores ao algoritmo J48. Contudo, o algoritmo random forest foi superior aos demais para as três espécies do gênero Qualea. Conclui-se que o algoritmo random forest apresentou-se como o mais robusto para a modelagem da distribuição potencial de habitat de espécies arbóreas.Palavras-chave: inteligência artificial; árvore de decisão; random forest; redes neurais artificiais. MACHINE LEARNING ALGORITHMS FOR MODELING THE POTENTIAL DISTRIBUTION HABITAT OF TREE SPECIES ABSTRACT: The aim of the present study was to evaluate three methods of machine learning (decision tree-J48, random forest and artificial neural networks) to model the potential habitat distribution of the ten most abundant tree species of the São Francisco river watershed. The presence/absence tree species data were from 77 fragments sampled with 2,234 plots. We used 12 categorical environmental variables from the Economic Ecological Zoning of Minas Gerais (ZEE/MG), as well as variables related to soil water balance (current and potential evapotranspiration, aridity and alpha index). The parameterization of the three algorithms was done with cv parameter algorithm of the WEKA software. The results showed the applied algorithms were statistically similar for 60% of the tree species. The random forest and multilayer perceptron algorithms were statistically similar considering the Eugenia dysenterica and superior to J48 algorithm. However, the random forest algorithm was superior to the other for the three species of Qualea genera. The conclusion is the random forest was the most robust model for the potential distribution habitat of tree species.Keywords: artificial intelligence; decision trees; random forest; artificial neural networks.

O objetivo do presente trabalho foi avaliar o efeito de técnicas de raleio na produção e em características morfológicas de frutos de tomate. O tomateiro foi submetido a seis diferentes técnicas de raleio de frutos, com condução de diferentes números de racemos por planta. Ao final do experimento, após a colheita, foi avaliado o diâmetro médio longitudinal (DLM) e transversal (DTM) dos frutos, número de frutos por planta (NF), peso médio de frutos (PMF), produção total por planta (Prod T), produção de frutos grande (Prod G), médio (Prod M) e pequeno (Prod P), e a frequência relativa de cada classe de diâmetro. A técnica de raleio que consistiu na condução de plantas com 7 racemos, com 6 frutos por racemoaté o 4° racemo e acima deste, 4 frutos por racemo(R3) aumentou a Prod G, a frequência relativa da classe grande, a Prod T, DTM, DLM e PMF. Técnicas de raleio que resultaram em maior NF reduziram a qualidade morfológica dos frutos, bem como a condução de plantas com menos de sete racemos reduziu a produção de tomates. A adoção da técnica R3 no tomateiro reuni alta produção de frutos por planta com aumento da qualidade morfológica do fruto.Palavras-chave: Solanum lycopersicum L.; desbaste de frutos; qualidade de tomates; classes de diâmetro de frutos; relação fonte:dreno. PRODUCTIVE AND MORPHOLOGICAL FEATURES OF TOMATO FRUITS IN RESPONSE TO THINNING SYSTEMS ABSTRACT: The aim of this work was to evaluate the effect of thinning techniques on the production and morphological features of tomato fruits. Tomato plants were submitted to six different thinning practices, with different numbers of racemes per plant. At the end of the experiment, the mean longitudinal diameter (MLD) and transverse diameter (MTD) of fruits, number of fruits per plant (NF), average fruit weight (AFW), total production per plant (T Prod), production of fruits large (Prod L), middle  (Prod M) and small (Prod S), and the relative frequency of each diameter class. The thinning technique, which consisted in the conduction of plants with 7 racemes, with 6 fruits per raceme up to the 4th raceme and above this, 4 fruits per raceme (R3) increased the Prod L, the relative frequency of the large class, T Prod, MLD, MTD, and AFW. Thinning techniques that provide greater NF reduced the morphological quality of fruits, as well as the conduction of plants with less than seven racemes decreased tomato production. Adoption of the R3 technique in the tomato plants bring together high fruit production with an increase in the fruit morphological quality.Keywords: Solanum lycopersicum L.; fruit pruning; tomato quality; fruit diameter classes; source:sink ratio.

Published: September 2019

Purpose: Prenatal multivitamins are recommended in pregnancy. This study assessed food and supplement intakes of folate, vitamin B12 (B12), vitamin D, and choline in pregnant women living in Southern Ontario in comparison with current recommendations.

Methods: Women recruited to the Be Healthy in Pregnancy RCT (NCT01693510) completed 3-day diet/supplement records at 12–17 weeks gestation. Intakes of folate, B12, vitamin D, and choline were quantified and compared with recommendations for pregnant women.

Results: Folate intake (median (min, max)) was 1963 μg/day dietary folate equivalents (153, 10 846); 90% of women met the Estimated Average Requirement (EAR) but 77% exceeded the Tolerable Upper Intake Level (UL) (n = 232). B12 intake was 12.1 μg/day (0.3, 2336); 96% of women met the EAR with 7% exceeding the EAR 100-fold (n = 232). Vitamin D intake was 564 IU/day (0.0, 11 062); 83% met the EAR, whereas 1.7% exceeded the UL (n = 232). Choline intake was 338 mg/day (120, 1016); only 18% met the Adequate Intake and none exceeded the UL (n = 158).

Conclusion: To meet the nutrient requirements of pregnancy many women rely on prenatal vitamins. Reformulating prenatal multivitamin supplements to provide doses of vitamins within recommendations to complement a balanced healthy diet would ensure appropriate micronutrient intakes for pregnant women.
F�ATURES OF INTERNATIONAL INVESTMENT IN THE ECONOMY OF UKRAINE
Authors: VLADYMYRSKA N.
Published: September 2019

Topicality. In the conditions of the economic crisis, in which the economy of Ukraine has been in recent years, the search for reasons that do not allow developing the economy properly and the intensification of areas for attracting investments, including foreign ones, is one of the priority issues. The article aims to explore the level of the investment climate in Ukraine, as well as to analyze the level of attracting foreign investment in the economy of Ukraine.
Aim and tasks. Investment attractiveness is largely shaped by the investment climate; therefore, we analyze the investment climate as a combination of legal, financial, political, and socio-cultural factors that predetermine the expediency of investing in the country. Estimated index of investment attractiveness of the country for 2009-2018 and the place of Ukraine in the rating of investment attractiveness of the countries of the world.
The article analyzes the volume of foreign direct investment in Ukraine, the structure of investment in the sectoral context and by investor countries of foreign direct investment over the ten-year period from 2010 to 2019.
Research results. Based on the study, it was found that the most attractive for foreign investors in the industry, during the analyzed period, remain the industry, especially processing, financial and insurance activities, wholesale and retail trade, real estate operations, scientific and technical activities, information and telecommunications.
It is determined that the main investor countries that invest more than 80% of foreign direct investment are twelve of the one hundred and thirty investment countries. The top five investor countries are Cyprus, the Netherlands, Germany, the United Kingdom and the Russian Federation, these countries form more than 60% of all international investments in the economy of Ukraine. The study revealed that almost a third of the international investment in the Ukrainian economy is Ukrainian capital, previously withdrawn from the country in offshore jurisdictions - round - tripping. These countries, apart from Cyprus, include Switzerland and the British Islands Verginsky.
Conclusion. The necessity of further formation of modern approaches to the creation of a favorable investment environment in the Ukrainian economy, based on the experience of countries such as Estonia in the taxation of withdrawn capital and world experience, is substantiated. Ukraine should also continue to cooperate with international institutions such as the OECD and develop areas of cooperation with investors under the MLI Convention, which will help reduce the movement of Ukrainian capital to low-tax countries and, accordingly, will affect the increase in investment in the Ukrainian economy.

The Ingathering of the Jewish (Moroccan) Diaspora
Authors: Moreno Aviad
Published: September 2019

Homeland/diaspora dichotomies are emblematic of the Zionist philosophy and, as a consequence, also in the common critical annals of long-lasting diasporic ethnicities among Jewish immigrants to Israel. This observation applies in particular to Jewish immigrants from Islamic countries, whose Eastern pre-immigration cultures conceivably contrast with the Western character of the national-Zionist venture. In this article, I focus on MABAT, an Israel-based hometown association of Jews from the former Spanish-dominated area in northern Morocco which, from its founding in 1979, embraced the Zionist notion of homecoming. I show how they came to form their own singular network in Israel, while appealing to their former hometowns, as well as to their emerging centres of diffusion in the Americas and Europe, thereby challenging commonly held assumptions of Israel/diaspora, East/West dichotomies in the annals of Jewish ethnicities in Israel.

Postglacial seismogenic deformations of an esker in the Northern Karelian Isthmus (south-east Fennoscandia)
Authors: Shvarev S. V.
Published: September 2019

The research area is located in the Northern part of the Karelian Isthmus between Lake Ladoga and the Gulf of Finland of the Baltic Sea. The terrain features are closely related to the tectonic structure of the crystalline basement, partially covered with thin deposition layer of the Last Glaciation and Holocene mostly. Accumulative forms are rarely but strongly correlated with the tectonic structure also. Most expressive features of accumulative topography are esker ridges that stretch for tens of kilometers. Analysis of eskers spatial distribution shows their close connection with the structural plan of the crystalline basement. One of the ridges under study was described in three sections where a lot of deformations in soft sediments, accompanied by deformations of the esker’s topography (in one case) were found. The nature and stratigraphic position of deformations indicates their appearance during the period of existence of the Baltic Ice Lake after the retreat of the ice sheet. Post-sedimentary deformations were accompanied by partial re-deposition of sedimentary strata. Deformations are represented by several types and generations. The ensembles of faults and fold deformations in the esker deposition kinematically connected with each other and coinciding along the strike with the structural lineaments demonstrate the influence of the activated tectonic structure to the formation of the sedimentary cover. The conjugation of normal and thrust faults, the presence of several “event horizons” with traces of liquefaction testify to the seismotectonic genesis of deformations and several strong earthquakes that occurred at different stages of the existence of the Baltic Ice Lake in the period 13.0–11.6 thousand years BP.
Use of singular spectral analysis in geomorphological studies in the Southern Primorye and the Peter the Great Bay of the Sea of Japan
Authors: Samchenko A. N.
Published: September 2019

This paper presents the results of geomorphological studies carried out using the singular spectral analysis (SSA) complemented with geological and geophysical data. The SSA method was used to study the topography of the shelf and adjacent land areas in two scales. The large scale study covered the whole territory of the Southern Primorye and the Peter the Great Bay, the small scale — a major part of the Peter the Great Bay and the adjacent land in the northwest-ern direction. This technique of the relief analysis gives an opportunity to select different groups of elevations (modes in the relief), isolating them among the others, and to carry out geomorpho-logical studies based on discrete changes in the relief levels. Based on the geological and geo-physical data, it was determined that the area is located on a massive granite block. By analyzing the first (“older”) modes of the decomposition of the relief of the studied area, contouring of the massive block was carried out, and the choice of the location of the experimental hydrophysical ground was explained.
On the hydrological role of the relief in the southern part of the Russian plain
Authors: Koronkevich N. I. , Dolgov S. V.
Published: September 2019

On the example of a southern part of the Russian Plain the surface slope runoff, the runoff from the hydrographic network and snow melt river runoff are considered. Based on the analysis of the data by water balance stations and the correlation of surface slope runoff values from different lands to the zonal river runoff value, the zonal values of the spring surface slope flow from separate lands located on loam and sandy loam soils are determined. Within agricultural lands there are fall plowed fields and non-plowed in autumn (stubble, layland, winter crops, perennial grasses). By the beginning of the spring flood, the soil at autumn-plowed fields is loosened and reduces the runoff, while on the fields that were not plowed in the autumn soil is compacted. In addition, the microtopography created by autumn plowing also contributes to the runoff reduction. The smallest surface slope runoff occurs under the forest. Differences in runoff increase in the direction from the southern part of the forest zone to the steppe areas. Taking into account the land composition and the mechanical composition of the soils, the weighted average values of the surface slope runoff were obtained for the period of the long-time average annual flow calculation (late 19th century and early 1960s). It is shown that subsequently there was a decrease in the spring surface slope runoff, initially as a result of the autumn plowing increase, and more recently, mainly as a result of changes in meteorological conditions, especially during the cold season (air temperature rising, frequent thaws, increased infiltration). In the overall structure of the spring river flood, along with a decrease in the share of surface slope runoff, the share of surface runoff formed in the hydrographic network increases, and especially the flow of infiltration origin (verhovodka and underground runoff). In the steppe zone the structure of river flow has changed most significantly.

Unsteady State Lightweight Iris Certification Based on Multi-Algorithm Parallel Integration
Authors: Shuai Liu , Yuanning Liu , Xiaodong Zhu , Kuo Zhang , Tong Ding , Xinlong Li , Chaoqun Wang
Published: September 2019

Aimed at the one-to-one certification problem of unsteady state iris at different shooting times, a multi-algorithm parallel integration general model structure is proposed in this paper. The iris in the lightweight constrained state affected by defocusing, deflection, and illumination is taken as the research object, the existing algorithms are combined into the model structure effectively, and a one-to-one certification algorithm for lightweight constrained state unsteady iris was designed based on multi-algorithm integration and maximum trusted decision. In this algorithm, a sufficient number of iris internal feature points from the unstable state texture were extracted as effective iris information through the image processing layer composed of various filtering processing algorithms, thereby eliminating defocused interference. In the feature recognition layer, iris deflection interference was excluded by the improved methods of Gabor and Hamming and Haar and BP for the stable features extracted by the image processing layer, and two certification results were obtained by means of parallel recognition. The correct number of certifications for an algorithm under a certain lighting condition were counted. The method with the most correct number was set as the maximum trusted method under this lighting condition, and the results of the maximum trusted method were taken as the final decision, thereby eliminating the effect of illumination. Experiments using the JLU and CASIA iris libraries under the prerequisites in this paper show that the correct recognition rate of the algorithm can reach a high level of 98% or more, indicating that the algorithm can effectively improve the accuracy of the one-to-one certification of lightweight constrained state unsteady iris. Compared with the latest architecture algorithms, such as CNN and deep learning, the proposed algorithm is more suitable for the prerequisites presented in this paper, which has good environmental inclusiveness and can better improve existing traditional algorithms’ effectiveness through the design of a parallel integration model structure.

Viticulture, as a large part of the agriculture sector of the South Moravian Region, represents significant erosion-prone land use in which soils face various agronomic issues, such as poor organic carbon levels, erosion, and fertility loss. Service crops providing a so-called ecosystem service can reduce erosion and runoff, regulate pests and weeds and increase soil organic matter and fertility. However, these crops may generate some disservices, such as water and nutrient competition; and thus, it is important for winegrowers to find applicable options for service crops depending on local soil, climate conditions, and the expected service. Inter-row management in the South Moravian Region varies from bare soils to grass cover to different types of cover with herbaceous (flowering) species. A total of 113 vineyard sites were evaluated during the years 2016 and 2017. This study presents the actual state of inter-row management in vineyards and comparison within six wine-growing regions. A two-year evaluation shows significant differences in prevalent greening management between regions. Bare soil in vineyards, the most erosion-prone vineyard floor management, appear from 10% (e.g., Bzenec, Valtice) to 19% (e.g., Mikulov, V. Bílovice) of vineyard area within evaluated regions. Bare soil management is mostly used in new plantations to reduce water and nutrient competition; however, the erosion and the runoff rates are generally higher on this variant compared to other types of cover crop management, especially on slopes. Although, alternate greening is the most used type occurring from 50% to 74% of vineyards area in five of the six selected regions, the type of inter-row vegetation differs considerably. While in Bzenec and Mikulov there is a higher appearance of herbaceous cover with native species in later succession stages, in Velké Bílovice and Valtice grass cover and commercial plant mixtures are more frequent. Knowledge current stage can be useful for planning new plantation or anti-erosion measures.

The use of organic amendments in agriculture is a common practice due to their potential to increase crop productivity and enhance soil health. Indeed, organic amendments of different origin and composition (e.g., animal slurry, manure, compost, sewage sludge, etc.) can supply valuable nutrients to the soil, as well as increase its organic matter content, with concomitant benefits for soil health. However, the application of organic amendments to agricultural soil entails a variety of risks for environmental and human health. Organic amendments often contain a range of pollutants, including heavy metals, persistent organic pollutants, potential human pathogens, and emerging pollutants. Regarding emerging pollutants, the presence of antibiotic residues, antibiotic-resistant bacteria, and antibiotic-resistance genes in agricultural amendments is currently a matter of much concern, due to the concomitant risks for human health. Similarly, currently, the introduction of microplastics to agricultural soil, via the application of organic amendments (mainly, sewage sludge), is a topic of much relevance, owing to its magnitude and potential adverse effects for environmental health. There is, currently, much interest in the development of efficient strategies to mitigate the risks associated to the application of organic amendments to agricultural soil, while benefiting from their numerous advantages.

Protein hydrolysates (PHs) are organic non-microbial biostimulants having beneficial effects on plants. The study was designed to assess the effects on plants by the applications of PHs obtained from Trichoderma isolates grown on keratin wastes. Trichoderma isolates were characterized for indole-3-acetic acid and siderophores production, activity of lytic enzymes, phosphorous solubilization and inhibition of pathogens growth, using qualitative specific tests. Fungal isolates were cultured on a medium with keratin wastes (wool and feathers) to obtain PHs. Fungal PHs were tested in vivo for plant biostimulant action, as follows: (i) seeds germination test; (ii) activation of plant proton pump; (iii) evaluation of effect on tomato seedling growth. PHs from T. asperellum cultured on feathers medium reached the highest values for all parameters recorded (plant height and diameter, number of leaves and branches), with the exception of those for plant biomass, which were maximum for the wool medium. The metabolites released by keratin degradation under the activity of selected T. asperellum isolate improved crop health and productivity. The use of PHs can be a reasonable solution for the environmental pollution of by-products from the food chain, as well as for the replacement of chemical fertilizers with microbial formulations to stimulate plant growth.

Feeding frequency in one day is thought to be associated with nutrient metabolism and the physical development of the body in both experimental animals and humans. The present study was conducted to investigate transcriptomic responses in the liver and jejunal mucosa of pigs to evaluate the effects of different feeding frequencies on the body’s metabolism. Twelve Duroc × Landrance × Yorkshire growing pigs with an average initial weight (IW) of 14.86 ± 0.20 kg were randomly assigned to two groups: feeding one time per day (M1) and feeding two times per day (M2); each group consisted of six replicates (pens), with one pig per pen. During the one-month experimental period, pigs in the M1 group were fed on an ad libitum basis at 8:00 am; and the M2 group was fed half of the standard feeding requirement at 8:00 am and adequate feed at 16:00 pm. The results showed that average daily feed intake, average daily gain, feed:gain, and the organ indices were not significantly different between the two groups (p > 0.05). The total cholesterol (T-CHO), triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), and low-density lipoprotein-cholesterol (LDL-C) concentrations in the serum, and the TG concentration in the liver in the M2 groups were significant lower than those in the M1 group, while the T-CHO concentration in the liver were significant higher in the M2 group (p < 0.05). Jejunal mucosa transcriptomic analysis showed the gene of Niemann-Pick C1-Like 1 (NPC1L1), Solute carrier family 27 member 4 (SLC27A4), Retinol binding protein 2 (RBP2), Lecithin retinol acyltransferase (LRAT), Apolipoprotein A (APOA 1, APOA 4, APOB, and APOC 3) were upregulated in the M2 group, indicating that fat digestion was enhanced in the small intestine, whereas Perilipin (PLIN1 and PLIN2) were downregulated, indicating that body fat was not deposited. Fatty acid binding proteins (FABPs) and Acetyl-CoA acyltransferase 1 (ACAA1) were upregulated in the M2 group, indicating that two times feeding daily could promote the oxidative decomposition of fatty acids. In conclusion, under the conditions in this study, the feeding frequency had no significant effect on the growth performance of pigs, but affected the body’s lipid metabolism, and the increase of feeding frequency promoted the fat digestion in the small intestine and the oxidative decomposition of fatty acids in the liver.
Investigating the Role of Prolactin as a Potential Biomarker of Stress in Castrated Male Domestic Dogs

Published: September 2019

Prolactin has been recently regarded as a potential biomarker of both acute and chronic stress in several species. Since only few studies until now have focussed on domestic dogs, this study was aimed at evaluating whether prolactin, cortisol and stress behaviour correlated with each other in sheltered dogs. Both cortisol and prolactin analysis were performed in serum samples through a hormone-specific ELISA kit. For each dog, a stress score was calculated by summing the number of occurrences of stress-related behaviours. The presence/absence of fear during the time spent in the collection room was also scored for each individual. Results revealed a weak negative correlation between cortisol and prolactin levels. Neither of the hormones was correlated with the stress score, nor did their values seem to be influenced by showing fear in the collection room. The weak negative correlation found between cortisol and prolactin values agrees with results obtained in other studies, indicating that prolactin response might be an alternative to cortisol response. This, together with the high serum prolactin levels compared to those reported by other authors for healthy domestic dogs, may indicate that prolactin might be a good biomarker of chronic stress, and although further studies are needed to better understand the potential role of prolactin in the evaluation of canine welfare.

EU legislation states that all pigs must have access to material that allows them to perform investigation and manipulation activities, thereby reducing the risk of pigs performing damaging behaviours (e.g., tail, ear and flank biting). We aimed to determine associations between damaging behaviours performed by finisher pigs, the related lesions and the use of different types of enrichment. Six randomly selected pens of finisher pigs were observed for 10 min each on 31 commercial pig farms in Ireland. All pigs were counted and the number of pigs affected by tail, ear and flank lesions was recorded. During the last 5 min, all occurrences of damaging behaviour (tail-, ear- and flank-directed behaviour) were recorded. The type (chain, plastic or wood) and number of accessible enrichment objects/pen was recorded. Chains were the most common (41.4% of farms), followed by plastic (37.9%) and wood (20.7%). Damaging behaviour was more frequent on farms that provided chains compared to plastic or wood. Farms with chains were associated with a higher frequency of flank-directed behaviour and tended to be associated with a higher frequency of tail-directed behaviour compared to farms that provided plastic devices. The prevalence of lesions tended to be higher on farms where chains were provided compared to wooden enrichment devices, mostly driven by a difference in the prevalence of mild tail lesions. Results support expert opinions that despite being commonly used, chains did not fulfill a role in reducing damaging behaviours and associated lesions in finisher pigs compared to other forms of enrichment.

Lonicera caerulea L. (haskap) berries are widely known for their richness in anthocyanins. In this study, such fruits were assessed for their nutritional and chemical composition, but also as sources of anthocyanins with great colouring properties to be applied in foodstuff. Haskap presented high levels of water, four free sugars (mainly fructose and glucose), five organic acids (mainly citric, malic, and quinic), α- and γ-tocopherol, twenty fatty acids (with prevalence of linoleic acid), and eight phenolic compounds, among which six were anthocyanins (mainly cyanidin-3-O-glucoside). The extract presented great antioxidant properties, evaluated through TBARS and OxHLIA assays, as well as antimicrobial capacity against six bacteria and six fungi. Two colourants were obtained by spray-drying haskap juice with maltodextrin and a mixture of maltodextrin and arabic gum. These formulations were stable over 12 weeks of storage at room and refrigerated temperature, without significant variations in colour parameters and in anthocyanins concentration. They were considered safe for consumption once neither microbial contamination nor cytotoxicity in non-tumour cells were detected. The results obtained allow for the consideration of haskap as a promising source of colourants to be applied not only in the food industry, but also in other fields that rely on artificial colourants.

A single-phase flux reversal machine (FRM) has many advantages in high-speed applications because of its simple and reliable rotor structure without magnets or winding, simple and cheap concentrated stator windings, high efficiency, and power density. However, the major problem of single-phase motors is the high torque ripple, which shortens their lifetime and causes noise and vibrations, not only in the machine, but also in the mechanisms coupled therewith. This paper presents a novel three-phase machine consisting of three single-phase machines, having a common shaft aiming to reduce the torque ripple and to improve motor behavior. In this paper, the mathematical model of the single-phase flux reversal motor, as well as the conversion procedure of the single-phase motor parameters to the three-phase ones, is considered. Furthermore, an optimization procedure of the motor and choosing the optimization objectives are done. The finite element two-dimensional (2D) method is used to simulate the machine and to show the results.

Electrostatically-defined quantum dots (QDs) in silicon are an attractive platform for quantum computation. Localized single electron spins define qubits and provide excellent manipulation and read-out fidelities. We propose a scalable silicon-based qubit device that can be fabricated by industry-compatible processes. The device consists of a dense array of QDs localized along an etched silicon nano-ridge. Due to its lateral confinement, a simple dense array of metallic top-gates forms an array of QDs with controllable tunnel-couplings. To avoid potential fluctuations because of roughness and charged defects at the nano-ridge sidewall, the cross-section of the nano-ridge is trapezoidal and bounded by atomically-flat {111} facets. In addition to side-gates on top of the low-defect oxidized {111} facets, we implement a global back-gate facilitated by the use of silicon-on-insulator. The most relevant process modules are demonstrated experimentally including anisotropic wet-etching and local oxidation of the silicon nano-ridge, side-gate formation with chemical-mechanical polishing, and top-gate fabrication employing the spacer process. According to electrostatic simulations, our device concept allows forming capacitively-coupled QD double-arrays or adjacent charge detectors for spin-readout. Defining a logical qubit or realizing a single electron conveyor for mid-range qubit-coupling will be future applications.
