Time-Dependence of Stop Marks in Warp-Knitted Fabrics
Authors: Hellert Christian , Kieren Michael , Ehrmann Andrea
Published: June 2022

Stop marks are one of the most frequently occurring errors in warp-knitted fabrics. They become visible in a fabric each time a warp-knitting machine stops and restarts. Nevertheless, investigations of such stop marks are rarely found in scientific literature. Here, we report on time-dependent investigations of stop marks in warp-knitted fabrics. Microscopic examination of stop marks after stopping times ranging between 1 s and 7 weeks revealed a superposition of the common stop mark due to imperfectly matching rotational speeds of the warp beam and main shaft, and an additional effect due to relaxation in the machine.
Landschaft in situ. Der Beitrag von Atmosphären zum Verständnis der Konstruktion von Landschaft
Authors: Crossey Nora , Dittel Julia , Kazig Rainer , Thiollière Pascaline , Weber Florian
Published: June 2022

This paper puts forward a proposal for the consideration of atmospheres within the analysis of the social construction of landscape(s). Starting out from an overview of approaches in constructivist landscape research, focusing on the German speaking world, we may confirm an increased interest in the role of subjective multisensorial experience with regard to constructions of landscape(s), which has, however, not yet been reflected in current research approaches. The concept of atmosphere, with its consideration of multisensorial in situ-encounters, may be able to contribute to the scholarly discussion. Following a presentation of core ideas of the concept of atmosphere(s), we show that, on a conceptual level, the conscious experience of atmospheres and their effects may inform the construction of landscapes. Furthermore, in a methodological section we illustrate on the basis of two exploratory examples, how the influence of atmospheres on subjective constructions of landscape(s) may be empirically accessible. The paper closes with a discussion of our proposal within current trajectories of the Anglophone landscape geography.

Authors: HOU Yongmei
Published: June 2022

Objective To explore the present status of adult attachment and mental health, and analyze the impact of adult attachment on mental health among medical undergraduates. Methods Stratified random sampling was used to select 855 medical undergraduates from Guangdong Province, China. They were investigated with Experiences in Close Relationships Inventory (ECR) and Symptom Check-List 90 (SCL-90). Results ⑴ The scores in the both dimensions of ECR, as well as the total score of SCL-90 were (3.89±0.74), (3.77±0.55) and (1.87±0.47), respectively. The scores of obsessive-compulsive and interpersonal sensitivity were above 2.0, the lower score limit of postive symptom. (2) Multiple linear stepwise regression showed that both attachment anxiety and attachment avoidance positively predicted the total score of SCL-90 (β=.302, .280, all P<.001). Conclusion The adult attachment and mental health of medical undergraduates need to be improved. Adult attachment may be an important influencing factor of mental health.
English Neologisms and Borrowings in Media
Authors: Poladova Sabina Elkhan
Published: June 2022

This article is divided into two main parts: neologisms and borrowings in media. One of the main features of the modern spoken and written language has been the use of borrowed words, primarily of American-English origin. The lexical environment of a modern person, therefore, contains a significant number of foreign words and neologisms, the use of which seems inevitable for successful communication. Considering the features of the use of borrowings and neologisms in the media is especially significant in modern conditions. The main purpose of this article is to determine the role of its two themes, and to study the features of the translation of neologisms and borrowings from English into Azerbaijani in connection with the constant updating of the English dictionary against the background of the current ever-changing environment.
The State of the UBI Debate: Mapping the Arguments for and against UBI
Authors: Afscharian Dominic , Muliavka Viktoriia , Ostrowski Marius S. , Siegel Lukáš
Published: June 2022

This article provides a map of the UBI debate, structured into the main themes that guide and group the arguments on both sides. It finds that UBI’s supporters and opponents both draw on core principles of justice and freedom, focusing on need and poverty, discrimination and inequality, growth, social opportunity, individuality, and self-development. From an economic perspective, they both appeal to business concerns about efficiency, risk, flexibility, and consumption, as well as labour interests on work fulfilment, working conditions, remuneration, and bargaining. Likewise, they focus on political questions around welfare state reforms, redistribution, taxation and funding sources, democratic citizenship, and the prospects for cross-party policy coalitions. By providing an overview of the thematic pillars of the UBI debate, this article helps researchers and activists locate and orient themselves within the wider spectrum of opinion on UBI.
Online comprehension of conditionals in context: A self-paced reading study on wenn (‘if’) versus nur wenn (‘only if’) in German
Authors: Barthel Mathias , Tomasello Rosario , Liu Mingya
Published: June 2022

Comprehending conditional statements is fundamental for hypothetical reasoning about situations. However, the online comprehension of conditional statements containing different conditional connectives is still debated. We report two self-paced reading experiments on German conditionals presenting the conditional connectives wenn (‘if’) and nur wenn (‘only if’) in identical discourse contexts. In Experiment 1, participants read a conditional sentence followed by the confirmed antecedent p and the confirmed or negated consequent q. The final, critical sentence was presented word by word and contained a positive or negative quantifier (ein/kein ‘one/no’). Reading times of the two quantifiers did not differ between the two conditional connectives. In Experiment 2, presenting a negated antecedent, reading times for the critical positive quantifier (ein) did not differ between conditional connectives, while reading times for the negative quantifier (kein) were shorter for nur wenn than for wenn. The results show that comprehenders form distinct predictions about discourse continuations due to differences in the lexical semantics of the tested conditional connectives, shedding light on the role of conditional connectives in the online interpretation of conditionals in general.
A review of online communication research in Hungary
Authors: Háló Gergő
Published: June 2022

Ever since the mid-nineties, Internet-related communication research has been a growing field in Hungary. Notwithstanding, scholars have so far failed to deliver a systematic overview regarding the historical and topical trends defining the field. To mend this gap, we provide a systematic literature review concerning the main trends and developments of Hungarian online media research as indicated by the most influential journals of the field between 1995 and 2021. Given its historical legacy, Hungary serves as an indicative case study from the socialist and post-socialist Central and Eastern European region, where following the repressive political regime of the Soviet Union, the development of social scientific fields was rendered virtually impossible for decades. In this study, the major research traditions of the field – new media and the Internet; information society; inequalities and the digital divide; education and digital literacy; e-governance; social media; video games; Big Data; algorithms and artificial intelligence – as well as their historical development are assessed. Furthermore, we formulate reflections regarding the results with a high emphasis on current internationalization processes in the region, as well as the prospects of Hungarian communication research within the context of these changes and of the historical-cultural legacies of the country.
Do We Finally Know What the Neolithic Is?
Authors: Nowak Marek
Published: June 2022

Over 20 years ago, an inspiring text by Lech Czerniak (The Neolithic – What’s That?) on understanding the concept of the Neolithic was published. For the present author, the Lech Czerniak’s discourse on the Neolithic was for many years and, to a large extent still is, a conceptual basis for understanding and presenting this issue. This contribution is an examination of the current relevance of Lech Czerniak’s theses. Furthermore, starting from this basis, a subjective attempt will be made to put the topic in some order, since a lack of clarity as to what the Neolithic is and what is not hampers and complicates research activities. Particularly, perhaps a fundamental issue will be assessed whether the concept of Neolithic in any measure reflects the past reality or reflects only our perceptions of that past. Conclusions resulted of the argumentation assume that there were indeed different and real Neolithics in the past. However, these Neolithics had a common denominator, in the form of “new” socio-organizational, ideological, mental, and consequently also meaning structures. They were a prerequisite for the existence of the Neolithic formation. Situations that can be labelled as the Neolithic are reflected archaeologically by the predominance of elements of the “Neolithic package” within a given sector of the cultural system.
Households and Hamlets of the Brześć Kujawski Group
Authors: Bogucki Peter , Grygiel Ryszard
Published: June 2022

Over several decades, we have written extensively about the household as a fundamental organizational unit of the Neolithic society. Starting from our definition of the household cluster at Brześć Kujawski 3 and the detailed analysis of household activities at House 56 at Brześć Kujawski 4, we continue to consider the household as the locus of decision-making and resource allocation even as our thinking has evolved over the intervening years. At the same time, Neolithic households functioned within local concentrations of settlement in which they interacted with other such units. We characterize such local social entities as “hamlets,” adapting the definition used by the anthropologist Frank Cancian to refer to institutionalized alliances of domestic groups in which affiliation is demonstrated through residential proximity. We have studied two such hamlets of the Brześć Kujawski Group: the Osłonki-Miechowice-Konary hamlet and the Smętowo hamlet consisting of Brześć Kujawski and Pikutkowo. We characterize these hamlets to show how they extend our original conception of household-based societies to develop a robust understanding of local Neolithic communities.
An analysis of the evolution of Chinese cities in global scientific collaboration networks
Authors: Cao Zhan , Derudder Ben , Dai Liang , Peng Zhenwei
Published: June 2022

This paper examines the emergence of China – now the world’s largest source of scientific publications – in global science from the perspective of the connectivity of its major cities in interurban scientific collaboration networks. We construct collaboration networks between 526 major cities (including 44 Chinese cities) for 2002–2006 and 2014–2018 based on co-publication data drawn from the Web of Science. Both datasets are analyzed using a combination of different centrality measures, which in turn allows assessing the shifting geographies of global science in general and the shifting position of Chinese cities therein in particular. The results show that: (1) on a global scale, the bipolar dominance of Europe and North America has waned in light of the rise of Asia-Pacific and especially China. Most Chinese cities have made significant gains in different centrality measures, albeit that only a handful of cities qualify as world-leading scientific centers. (2) The rise in connectivity of Chinese cities is therefore geographically uneven, as cities along the East Coast and the Yangtze River corridor have become markedly more prominent than cities in other parts of China. The uneven trajectories of Chinese cities can be traced back to changing institutional, economic, and geopolitical contexts. (3) Evolution in the global scientific collaboration network exhibits strong ‘Matthew Effects’, which can be attributed to the path-dependent nature of knowledge production and preferential attachment processes in scientific collaboration.
Assessing Farmers' Perception towards the Effectiveness of Sustainable Land Management Practices in the Teleyayen Sub-Watershed of the Northeastern Highlands of Ethiopia
Authors: Assefa Agidew Alem-meta , Singh K. N.
Published: June 2022

The main objective of sustainable land management practice is to integrate people’s coexistence with nature over the long-term, so that the provisioning of supporting services of ecosystems. Hence, understanding farmer’s perception on the effectiveness of sustainable land management is vital. Data were collected using a survey questionnaire, focus group discussions, key informant interviews, and field observations. Independent-sample t-test, chi-square, percentage, mean and standard deviation were employed to analyze the data. The result of the study indicated that land tenure security problem (32.6%) is one of the major factors affecting farmers land management practices, followed by unaffordable price of fertilizer (27%), lack of assistance from development agents (15.8%), lack of credit access (14%), and negative perception towards land management practices (10.7%). Sixtyfive percent of the focus group discussion participants also reported that the sustainable land management practices conducted in their area is not effective because of farmers’ reluctance to participate in soil and water conservation practices, lack of incentives, poverty, and lack of awareness about the long-term benefits of such practices. Moreover, the chi-square results of gender of the household head (X2=8.716), land tenure security (X2=6.595), and educational status of the household head (X2=11.738), found to be significant in explaining the correlation between farmers’ perception and the effectiveness of sustainable land management practices. Therefore, exploring farmers’ perception towards the effectiveness of sustainable land management practices is helpful because it would improve the quality of the environment so that farmlands will remain productive for a long period of time.

The purposes of the study were to describe the socio-economic profile of shrimp farmers and to find out the factors influencing farmers’ profitability of the shrimp farming in the study area. The study was conducted in Bagerhat and Khulna districts of Bangladesh. A total number of 120 shrimp farmers were selected randomly as the sample of the study. The final data were collected during 1st November to 31st December, 2017 by using an interview schedule. Ten selected characteristics of the farmers were considered as the independent variables of the study. Farmers’ profitability of shrimp farming was considered as the dependent variable. The majority (55.8%) of the farmers said that shrimp farming is profitable. Multinomial logistic regressions analysis indicated that age, level of education, family size, experience in shrimp farming and organizational participation had significant positive contribution to their profitability. They were faced different problems in different level which are needed to mitigate by both public and private initiatives to increase the level of profitability. Key words: Farmer, profitability, shrimp farming and Bangladesh.
Optoception: Perception of Optogenetic Brain Perturbations
Authors: Luis-Islas Jorge , Luna Monica , Floran Benjamin , Gutierrez Ranier
Published: June 2022

How do animals experience brain manipulations? Optogenetics has allowed us to manipulate selectively and interrogate neural circuits underlying brain function in health and disease. However, little is known about whether mice can detect and learn from arbitrary optogenetic perturbations from a wide range of brain regions to guide behavior. To address this issue, mice were trained to report optogenetic brain perturbations to obtain rewards and avoid punishments. Here, we found that mice can perceive optogenetic manipulations regardless of the perturbed brain area, rewarding effects, or the stimulation of glutamatergic, GABAergic, and dopaminergic cell types. We named this phenomenon optoception, a perceptible signal internally generated from perturbing the brain, as occurs with interoception. Using optoception, mice can learn to execute two different sets of instructions based on the laser frequency. Importantly, optoception can occur either activating or silencing a single cell type. Moreover, stimulation of two brain regions in a single mouse uncovered that the optoception induced by one brain region does not necessarily transfer to a second not previously stimulated area, suggesting a different sensation is experienced from each site. After learning, they can indistinctly use randomly interleaved perturbations from both brain regions to guide behavior. Collectively taken, our findings revealed that mice’s brains could “monitor” perturbations of their self-activity, albeit indirectly, perhaps via interoception or as a discriminative stimulus, opening a new way to introduce information to the brain and control brain-computer interfaces.
Living Too Long
Authors: Redmond Matthew
Published: June 2022

Matthew Redmond, “Living Too Long: Republican Time in Cooper’s Leatherstocking Novels” (pp. 29–55)

This essay first suggests that antebellum America’s cultural imagination was organized around patterns of generational succession unfolding across what I call “republican time,” and then explores the ways that James Fenimore Cooper’s Leatherstocking novels cross-examine and destabilize that pattern. Reading The Pioneers (1823), The Last of the Mohicans (1826), and The Prairie (1827) through the dual lenses of biopolitical criticism and temporality studies, I treat Natty Bumppo, with his stubborn refusal to die or even fully subside into the background of American life, as a friction against the machine of republican time and the idea of steady national progress it implies. With his peculiar perspective on national events, manifesting in a singular use of grammar, Natty’s character opens to Cooper’s readers certain alternative approaches to being in American time. Cooper’s writings thus demonstrate some of the ways that nineteenth-century American historical fiction, far from uncritically celebrating the forces of U.S. expansionism and imperialism, delivers an incisive critique of them.
“I Sort Rather with Those who Do Not Read”
Authors: Mendonck Wanne
Published: June 2022

Wanne Mendonck, “‘I Sort Rather with Those who Do Not Read’: Edward Carpenter, the Religion of Socialism, and the Prophetic Agitation of Literary Form” (pp. 56–90)

Edward Carpenter’s prose poem Towards Democracy (1883) constructs “new forms” to frame a radical voice that helped shape the British “socialist revival” of the 1880s and 1890s. Formal questions, however, have often been skirted in relation to Carpenter, or referred to his reputation as a disciple of Walt Whitman. This article argues, by contrast, that they can be productively asked in relation to a prophetic understanding of individual political and artistic agency, Carpenter’s working out of which is illustrated via his early play Moses (1875). Carpenter’s hybrid lyrical-narrative poetry is shaped by a deeply anxious self-consciousness about its political-spiritual duties, which expresses itself in a form that attempts to cancel out its own formalism. Its prose rhythms and hyperquotidian diction strain toward an immediacy that ultimately chafes against its own textuality. Only thus can Carpenter attain to the spontaneity and “inescapability” that support an understanding of pioneering, prophetic authorial agency that is at the basis of his conceptualization of politics, evolution, and queer sexuality. His poetry desires to intervene in the extratextual but is intratextually “agitated” by anxiety about the political viability of its own (counter)cultural authority and texture. This reading opens newly expansive ways of understanding Victorian literary form in its dialogic relationship with the political, arguing for a dynamic understanding that regards even the most experimental of late-nineteenth-century socialist poetry as responding to, and resisting, dilemmas of discursive authority and intelligibility implied by an embedded authorial model.

Organization of dialogue interaction of adults and children in the developmental environment of early groups
Authors: Gavrish Natalia , Bezsonova Olga
Published: June 2022

The article considers the problem of organizing dialogic interaction of adults and children in the developmental environment of early age groups. The article presents the results of theoretical research on the concepts of "dialogue", "interaction", "dialogue interaction". It is determined, that in most scientific sources dialogue is considered as a form, method and means of social contacts, which is realized by the individual in the subject-subject interaction. Educational influences, focused on dialogic interaction, able to stimulate speech and interpersonal interaction between children, are just beginning to develop and do not have wide practical application. Based on the following ideas about dialogue, the development of dialogical interaction of adults and young children in the educational space of ZDO, it is necessary to focus on solving the following tasks: establishing emotional contact between participants in educational interaction; mastering verbal and nonverbal means of communication; ability to perform actions together with other participants in the educational process. The main models of dialogic interaction, their uniqueness and effectiveness are described, namely: interaction that encourages the child to active cognition (cognitive development occurs during interaction with objects, mastering texts, actions in a specially created space, and the core of such a system is active action ), reorientation of the child's behavior in interaction with an adult (involves natural and logical changes in unwanted behavior of the child, which strengthens the child's sense of self-worth and shapes his/her character; the following types: sandwich, steps, triplets, pattern), supportive interaction task: to help the child to form a positive image of themselves, to realize their value and uniqueness; the following types: emotional, resource, co-existence support). The importance of maintaining consistency in the organization of interaction is emphasized: from the usual way in the usual conditions to the new way in the new unusual space. The algorithm of the organization of dialogue interaction is defined: I look, what the child does now; I feel and analyze what he/she needs now, what he/she expects from me; I give him/her what he/she needs. Emphasis is placed on the importance of compliance with speech strains when interacting with children early, compliance with the rules of communication by all participants in the educational process. Possibilities of application of the offered models of dialogue interaction in modern conditions of reforming of education in Ukraine are defined

Mathematical modeling of tourism development in territorial communities
Authors: Bihun Roman , Lytvyn Vasyl , Oleksiv Nazar
Published: June 2022

In this paper, the problems of development of associations of territorial communities in the tourism direction of economic development are considered.
The object of research is the improvement of territorial communities on the example of Ukraine. One of the most problematic places is the lack of funds for the development of existing large tourist complexes and the creation of new ones.
The study uses the idea that tourism development has a direct stimulating effect on the development of a number of important economic sectors. The use of a mathematical apparatus is also considered, which allows to analyze the main factors influencing the development of the tourism industry of territorial communities. A comprehensive solution of economic, social and environmental issues of sustainable tourism development is impossible without the development of mathematical models and supporting tools that allow predicting the main indicators of sustainable tourism development. The paper considers PLS-PM modeling using such internal consistency criteria as Cronbach’s Alpha coefficient, Dillon-Goldstein coefficient ρ, model reliability, mean variance. The purpose of the PLS-PM model is to obtain estimates of latent variables for further forecasting procedures for the development of the system. The processes taking place in the tourism industry are characterized by a complex interaction of economic, environmental and social factors. Their influence should be taken into account for the implementation of the sustainable tourism development strategy. The analysis of the model was also carried out with the help of a single coefficient of quality of the correspondence of the data model, which characterizes the quality of the internal and external models of the system.
Thanks to the listed tools, the statement is formed that the regulation of key factors of the tourism sector of the economic sector can have a positive impact on the development of national culture and economy in the united territorial communities. The created mathematical model clearly forms the conclusion that the development of tourism in local communities can become the engine of their sustainable economic development, given the available regional conditions.

Authors: Tvardovskyi Valentyn , Kravchenko Olha , Besedina Svetlana
Published: June 2022

The object of research is the process of monitoring the filling of garbage tanks of sorted garbage with the help of an automated system based on IoT solution. The paper analyzes existing IoT solutions for monitoring and monitoring the level of fullness of solid waste capacities. The research is important in light of sorting, storage and processing of garbage. The IoT model is proposed for monitoring and analyzing the system of waste recording of solid waste. The IoT solution project involves the creation of a software and hardware for the automated system. The interaction of hardware and software and the implemented root part of the project provide the opportunity to perform the main task – to obtain an assessment of the level of filling capacity for solid waste. Hardware is implemented using a device for analyzing the filling of garbage containers. It is possible to transfer data on the state of the filling of the container. The position of the lid or the same container is taken into account when the container will be inverted or the container lid will be raised. The device itself will be located on the lid on the inside of the container. Also, the device is equipped with a container for burning to prevent potential accidents and emissions into an atmosphere of harmful waste. Software implementation contains the level of programming of tasks for sensors IoT solutions and creates a friendly web-oriented interface. Software implementation is performed on the basis of client-server architecture. To operate the end points of the interaction of local and intermediate servers, the architectural style of REST with the transmission of information in the form of JSON is used. In order to administer an intermediate server, the client part is written on HTML and JavaScript. The application of the IoT solution allows to control the level of filling of containers, optimize routes of garbage trucks, which, in turn, reduces the cost of export of waste for regional operators. The scheme of information exchange in the system of garbage saving is constructed.

Published: June 2022

The object of research is the process of analyzing the customer churn of telecommunications companies based on machine learning methods. The existing problem is that, until recently, the process of customer churn was compensated by attracting new customers, but in the modern world, growth rates are constantly accelerating, the market is filled with a large number of competitors, which leads to a constant increase in customer requirements for products and services. In this regard, the process of attracting new customers becomes more costly and time-consuming, which in turn enhances the importance of maintaining an existing customer base.
The paper considers problematic aspects related to improving the accuracy of predicting the outflow of a company's customers through the use of machine learning methods. The conducted studies are based on the application of an approach implemented by combining the methods of decision trees and nearest neighbors. A positive result cannot be achieved by ignoring the existing resource constraints and requirements, which must be determined separately for each research case.
The relevance of the problem of analysis the outflow of customers for companies with many users is considered. A model for predicting the outflow of customers based on a combination of decision tree and nearest neighbor methods, which is used in the basis of the bagging method, is proposed. One of the features of this approach is the use of a test sample of normalized data. Accordingly, systems can use pre-known information, learn, acquire new knowledge, predict time series, perform classification, and in addition, they are quite obvious to the user. The prospect of choosing these methods is explained by the fact that they were used earlier in data analysis systems and provided sufficiently high-quality results.
The expediency and prospects of applying the proposed approach in the problem of analysis the outflow of customers of telecommunications companies are shown, as well as the design features of information technology and the results of software implementation.
Reduced energy losses during transportation of drilling fluid by Platform Supply Vessels
Authors: Maryanov Denys
Published: June 2022

The object of research is the process of drilling fluid transportation by Platform Supply Vessels. The subject of research is the energy losses when pumping drilling fluid from a platform supply vessel to an oil platform. The research was carried out on a vessel with deadweight of 3840 tons. It has been experimentally established that for a drilling fluid with an initial density of 1272 kg/m3 for transportation within 6–48 hours, the following changes in rheological characteristics occur:
– a layer with a density of 1235–962 kg/m3 is formed on the surface of the cargo tank;
– a layer with a density of 1283–1422 kg/m3 is formed in the bottom part of the tank;
– sedimentation resistance decreases by 3.89–47.82 %.
A variant of modernization of the drilling fluid transportation system by installing additional circulation pumps providing forced circulation of the drilling fluid between cargo tanks is proposed. Additional circulation of the drilling fluid with an initial density of 1272 kg/m3 for transportation within 6–48 hours ensures that the rheological characteristics are maintained in the following range:
– density on the surface of the cargo tank 1270–1232 kg/m3;
– density in the bottom of the tank 1288–1338 kg/m3;
– decrease in sedimentation resistance 1.42–7.92 %.
Similar results were established for drilling fluid with an initial density of 1323 kg/m3 and 1188 kg/m3.
To reduce energy losses, the process of unloading the fluid onto the oil platform is proposed to be performed at the completion of the technological process of unloading the vessel. At the same time, due to a decrease in draft and an increase in the height of the freeboard of the vessel, the static component of the pressure and hydraulic losses of the cargo pump decrease.
A set of studies for drilling fluids with different initial density (1272 kg/m3, 1188 kg/m3, 1323 kg/m3) confirmed that when using additional X-shaped drilling fluid circulation:
– relative performance of cargo pumps increases from 37–57 % to 88–96 %;
– the time of pumping the drilling fluid from the vessel to the oil platform is reduced from 7.1–8.5 to 3.3–3.8 hours.
The presented results confirm the expediency of using additional X-shaped circulation of the drilling fluid to reduce energy losses during transportation by Platform Supply Vessels.

The object of current research is the varietal composition of industrial vineyards in Ukraine. One of the most problematic aspects is the assortment of table grapes, which is represented by a limited number of varieties, especially in industrial viticulture. That is why the local market is saturated with imported table grapes.
Viticulturists have been creating Ukrainian grape varieties since the middle of the last century. 150 promising varieties and hybrid forms were bred. They combine high productivity and product quality with high rates of adaptability to the «risky» growing conditions of the Northern Black Sea coast. Many years of research confirmed a high level of pathogen, drought and frost resistance, winter hardiness, as well as a high level of quality traits. The inclusion of modern Ukrainian varieties in the regional assortments, especially with the usage of intensive cultivation, will ensure the development of sustainable viticulture. Due to genetically determined pathogen resistance, a significant reduction in pesticide load is possible, which in the future will ensure the transition to adaptive, and later to organic viticulture.
The results of the analysis of the composition and structure of the assortment of grapes in Ukraine are obtained and the new varieties with a high level and stability of productivity and product quality for improving the assortment are suggested.
This provides the opportunity to increase profitability by 250–350 % for table varieties, due to high productivity, reducing pesticide load, and increasing the price of product due to the visual appearance and high taste properties. Common varieties require 9–12 pesticide treatments, the usage of additional stimulants such as gibberellins, and other elements of production intensification to obtain the marketable product. New wine varieties also show significant economic potential, as they have higher winter hardiness, pathogen resistance, and exclusive wine characteristics.

Where to Add Actions in Human-in-the-Loop Reinforcement Learning

Published: June 2022

In order for reinforcement learning systems to learn quickly in vast action spaces such as the space of all possible pieces of text or the space of all images, leveraging human intuition and creativity is key. However, a human-designed action space is likely to be initially imperfect and limited; furthermore, humans may improve at creating useful actions with practice or new information. Therefore, we propose a framework in which a human adds actions to a reinforcement learning system over time to boost performance. In this setting, however, it is key that we use human effort as efficiently as possible, and one significant danger is that humans waste effort adding actions at places (states) that aren't very important. Therefore, we propose Expected Local Improvement (ELI), an automated method which selects states at which to query humans for a new action. We evaluate ELI on a variety of simulated domains adapted from the literature, including domains with over a million actions and domains where the simulated experts change over time. We find ELI demonstrates excellent empirical performance, even in settings where the synthetic "experts" are quite poor.
A simple method to reduce mesh dependency in modelling landslides involving brittle soils

Published: June 2022

This paper focuses on the numerical simulation of the deformation processes occurring in the slopes when soils with strain-softening behaviour are involved. In these circumstances, a progressive failure may occur with the consequent motion of the unstable soil mass in the post-failure stage. This problem can be only solved using advanced numerical techniques capable also of accounting for the occurrence of large deformations. However, the solution is generally mesh dependent and may be affected by lack of convergence. In this study, the material point method is employed to simulate the occurrence of large deformations, in conjunction with a strain-softening Mohr–Coulomb constitutive model, in which the shear strength parameters are reduced as a function of the accumulated deviatoric plastic strain, and a model parameter controlling the rate of strength decrease. To evaluate this parameter and to reduce the effects of the mesh dependency on the numerical solution, a novel procedure based on the results of direct shear tests is presented. This methodology is completely analytical and requires few parameters with a clear physical meaning and of simple experimental determination. Some simulations are performed to assess the reliability of the proposed procedure.
