Extrapolation of affective norms using transformer-based neural networks and its application to experimental stimuli selection
Authors: Plisiecki Hubert , Sobieszek Adam
Published: September 2023

Data on the emotionality of words is important for the selection of experimental stimuli and sentiment analysis on large bodies of text. While norms for valence and arousal have been thoroughly collected in English, most languages do not have access to such large datasets. Moreover, theoretical developments lead to new dimensions being proposed, the norms for which are only partially available. In this paper, we propose a transformer-based neural network architecture for semantic and emotional norms extrapolation that predicts a whole ensemble of norms at once while achieving state-of-the-art correlations with human judgements on each. We improve on the previous approaches with regards to the correlations with human judgments by Δr = 0.1 on average. We precisely discuss the limitations of norm extrapolation as a whole, with a special focus on the introduced model. Further, we propose a unique practical application of our model by proposing a method of stimuli selection which performs unsupervised control by picking words that match in their semantic content. As the proposed model can easily be applied to different languages, we provide norm extrapolations for English, Polish, Dutch, German, French, and Spanish. To aid researchers, we also provide access to the extrapolation networks through an accessible web application.

Published: September 2023

El objetivo de esta investigación fue evaluar la influencia de diferentes concentraciones y tipo de almidón sobre las propiedades de las películas, las mismas que fueron obtenidos por el método de Casting a partir de mezclas de almidón de banano verde y mandioca a concentraciones de 3 % y 4 % con quitosano comercial al 1 %, combinados con glicerina como agente plastificante y gel de sábila como agente antifúngico a concentración del 5 %. Las películas biodegradables formuladas se evaluaron en propiedades fisicoquímicas, mecánicas y biodegradables, aplicando diseño en bloques completamente aleatorizados. Se determinó que el espesor de las películas biodegradables aumenta de manera significativa, al aumentar la concentración de almidón, influyendo en la permeabilidad al vapor de agua, en la solubilidad y en el esfuerzo de tracción en el corte, pero no en la humedad; las películas biodegradables formuladas con almidón y quitosano tienen mejores propiedades mecánicas y biodegradables que las elaboradas solo con almidón. Así mismo, las propiedades de las películas biodegradables están influenciadas por la concentración de almidón y en menor medida por la fuente de almidón.

Published: September 2023

La producción actual de mezclas asfálticas en caliente para carreteras, aportan grandes cantidades de gases tóxicos nocivos para el medio ambiente debido a las altas temperaturas durante su preparación, por lo que se necesitan tomar medidas correctivas que sean sostenibles y económicas. Éstas medidas pueden verse reflejadas durante la elaboración de mezclas con la inclusión de otros materiales como aceites, polímeros o plásticos que influyan en la disminución de la temperatura. En la investigación se optó por incorporar un aceite crudo de palma de una planta de origen africano muy usado en la ciudad de Yurimaguas, Perú. Los aceites que se emplearon fueron del tipo industrial y artesanal a una temperatura de mezcla máxima de 130°C. Las variaciones de temperatura aceptables estuvieron en el rango de 128°C, 125,50°C, 120°C, 117,50°C y 115°C, considerando en todos los casos los requerimientos de laboratorio. Los resultados obtenidos indican que el aceite crudo de palma si influye en el diseño de mezclas asfálticas de hasta 115°C bajando considerablemente en 45°C respecto a una mezcla asfáltica en caliente típica, sin perder de lado la óptima relación estabilidad y flujo.

Authors: Arce Fernández Nilthon
Published: September 2023

El objetivo de la investigación fue mantener estable el nivel del agua en un tanque con variaciones generadas por la demanda del servicio. Se emplearon dos modelos matemáticos que permitieron estudiar la estabilidad, el modelo no lineal representado por una ecuación diferencial y el modelo lineal por una función de transferencia. Se utilizó el software Matlab/Simulink mediante un método numérico de Runge-Kutta para modelar y simular el proceso. Con las condiciones iniciales del 90 % en la apertura de la válvula de entrada y del 50 % en la apertura de la válvula de salida, la solución de ambos modelos alcanzó un nivel estacionario de h=1,8m. Debido a la demanda del servicio, la válvula de entrada se reajustó en +5 %, alcanzando la solución del sistema un nivel estacionario de h=2,005 m para el modelo no lineal y h=1,999 m para el modelo lineal. Finalmente, la válvula de salida se reajustó en +3 %, alcanzando la solución del sistema un nivel estacionario de h=1.785 m para el modelo no lineal y h=1.784m para el modelo lineal. Los modelos matemáticos empleados, permitieron estimar en menor tiempo con resultados esperados el nivel del agua, logrando así identificar la estabilidad del sistema.

El presente trabajo tuvo como objetivo evaluar la dinámica de crecimiento de Pisum sativum L bajo la aplicación de ácido giberélico en la provincia de Chachapoyas - Amazonas. El experimento se instaló bajo un diseño completo al azar, se tuvo un tratamiento T1: ácido giberélico y T0: testigo; se tuvo 8 repeticiones y 16 plantas en total. Se utilizaron macetas de polietileno, llenadas con sustrato (tierra agrícola + tierra de bosque en proporción 2:1 de v/v). El ácido giberélico se diluyó en etanol a una concentración de 10Mm, la misma que se aplicó con una micropipeta, sobre el ápice de la planta. Se encontró que el ácido giberélico tuvo efectos positivos en número de brotes (1.51), tamaño de brotes (5.63 cm) y tamaño de entrenudos (2.39 cm); no obstante, no presentó efectos positivos el tamaño total de la planta, materia seca y área foliar. Se concluye que el ácido giberélico favorece la elongación de algunas partes de la planta y poco efectúa en la biomasa seca y área foliar, comportándose igual que el testigo.

Russian International Register of Vessels as a Development Factor country's economy
Authors: Mitroshin Sergei G. , Mineev Valery I. , Urtmintsev Yuri N. , Lisin Alexander A.
Published: September 2023

For Russia, the return of the fleet under the national flag is of strategic importance. In the early 2000s, the reduction in the number of ships registered under the Russian flag became threatening to the transport and economic security of the state. The Russian maritime transport fleet, for the most part, operated under foreign flags. At the same time, relatively new vessels were taken offshore, and inefficient age-old vessels remained under the Russian flag. Under these conditions, foreign charterers intercepted a significant part of the transportation of Russian cargo, thereby displacing the Russian fleet. It became possible to change the situation in shipping and return the fleet under the Russian flag as a result of the regulation of monetary relations, customs and tax legislation. The features and reasons for the popularity of "convenient" flags are considered. Measures of state support for shipbuilding and shipping are analyzed, which contribute to the return of Russian shipowners to the national flag in the context of the functioning of the Russian International Register of Ships (RMRS). The analysis of the structure of the fleet in the Register and the trends in its change was carried out. The effectiveness of state support measures for domestic shipping and shipbuilding has been determined.
Analysis of conditions of expanding river transport participation in the grain crops shipment along the ITC «North – South»
Authors: Tsverov Vladimir V.
Published: September 2023

In the article the possibility of transporting grain crops produced in the regions of the Volga-Kama basin waterways along the international transport corridor (ITC) "North – South" by river transport is studied (mass bulk cargo, traditionally appropriate for this type of transport). For this purpose, the readiness of river ports of the Volga-Kama waterways basin for grain cargo shipment by water transport along the ITC "North – South" was assessed. Existing and proposed new chains for grain cargo delivery, which allow to increase the volume of grain cargo transportation by inland waterways to the countries of the Central and South Asia, have been considered. The main reason for river transport weak involvement as the seasonal nature of the internal waterways in the European part of the country was determined. A way of solving the problem of transporting grain cargo along the North – South ITC has been offered. This solution consists in creating a grain hub at one of the seaports of the Caspian Sea to receive, store and dispatch grain cargo delivered by the river ships during the navigation period between the navigations. The model of grain crops cargo flows along the inland waterways of the ITC "North – South" taking into account a grain hub creation was developed.

Authors: Kostyunichev Denis N. , Otdelkin Nikolay S. , Zimenkov Danila O.
Published: September 2023

The proposed experimental method of determining the losses of bulk cargo prone to dust formation allows, based on model researches results, to predict the bulk cargo losses amount when working with a grab in real conditions of cargo operations. The article presents developed by the authors experimental equipment, which makes it possible to obtain physical models of cargo scooping and unloading the grab processes, during which the most intense dust formation and the maximum losses amount of the reloaded cargo occur. In addition, the methods of using the specified experimental equipment are given, which provide for the determination of losses quantitative characteristics when using full-scale bulk cargo in researches, which is permissible under certain model parameters. Also, the methods provide for the possibility of determining the wind action speed influence on the amount of cargo losses from dusting, therefore, the researches were carried out in two stages - both in the absence of wind action during the grab operation, and in its presence. The range of wind impact velocities ranged from 0 to 10 m/s. As a result of processing modeling researches results, mathematical models of losses amount of a number of bulk cargoes during grappling overload considering wind impact were obtained.
Specific features of the development of an adaptive control system for special ship devices on the example of a trawl winch of a fishing vessel
Authors: Popov Vladimir V. , Ivanovskaya Aleksandra V. , Ivanovskii Aleksei N.
Published: September 2023

The trawl winch, being part of the auxiliary power plant of a fishing vessel, during its operation significantly affects the safety, reliability, and energy efficiency of the vessel as a whole. This is due to the peculiarity of the trawl winch. In addition to the existing external hydrometeorological factors, the dynamic performance of the machine is greatly influenced by the variability of the loading from the towed and raised fishing gear with the catch. Such non-stationary impacts have a negative impact on the performance and reliability of the equipment. Also, this type of lifting devices on a fishing vessel does not have a reserve. Therefore, when it fails, the fishing process also stops, which entails large economic losses. For smooth control of the winch operation in non-stationary conditions, an adaptive control system with an increased level of reliability is proposed in the work, which makes it possible to smoothly respond to load fluctuations. A control system diagram has been developed, as well as a diagram of the trawl winch drive itself, which is sensitive to changes in loading, the essence of which is to connect a backup hydraulic motor when the load from the towed or lifted object is exceeded.

Objectives. The aim of the study was to evaluate comparatively by scanning electron microscope (SEM) and energy dispersive spectrophotometry (EDS) the physical and chemical homogeneity of some luting materials used for cementation of three types of posts. Materials and method. We selected 12 irretrievable monoradicular teeth extracted in our dental offices. After extraction, all teeth were prepared for cementation with 4 different cements (NANOCORE DUAL, CEMBEST, PANAVIA SA and CEMENT-ONE) of three types of posts: prefabricated titanium post, FibreKleer 4x fiberglass post (Pentron) and post cast from NiCrMo alloy. Afterwards, the samples were embedded in resin and prepared metallographically for examination with the Phenom ProX scanning electron microscope equipped with an energy dispersive spectrophotometer with X Rays. Results. SEM studies provide valuable ultrastructural information regarding the degree of filling with luting materials. The four studied cements do not present an inhomogeneous composition in the EDS analysis, not having significantly increased values between the 2 analyzed points for each of the 12 samples taken in the study. Conclusions. Among the four luting materials studied comparatively, PANAVIA SA seems to best fill the existing spaces between posts and the limits of dental preparations, being closely followed by CEMENT-One and CEMBEST. In last place is NANOCORE DUAL, which presents discontinuities in the mass of material and at the border with the preparations.

Authors: Badtieva Viktoriya А. , Pogosova Nana V. , Ovchinnikova Anastasiya I.
Published: September 2023

INTRODUCTION. Medication non-adherence is one of the significant public health issue. Low adherence is one of the main reasons for the decrease therapeutic effect in patients with atrial fibrillation (AF), development of complications of AF, which leads to poor health outcomes and increased healthcare costs. Secondary prevention programs in cardiac rehabilitation may improve medication adherence in patients with AF.
AIM. To assess the impact of secondary prevention methods on medication adherence in patients after catheter ablation (CA) performed for paroxysmal AF.
MATERIALS AND METHODS. This is a prospective randomized controlled study with 3 parallel groups of patients with paroxysmal AF after CA (radiofrequency or cryoablation). Patients were randomized into 3 groups in 1:1:1 ratio. The 2 intervention groups received secondary prevention methods, including single-session in-person counseling and for 3 months of distant support (by phone in Group 1 or by e-mail in Group 2). Group 3 received usual care. Medication adherence was assessed using the 4-question scale Moriscos-Green. The medication adherence was evaluated at baseline and 12 months after CA.
RESULTS AND DISCUSSION. A total of 135 patients aged 35 to 79 years were enrolled (mean age 57 9 years, 51,8 % men). At 1 year of follow-up patients from intervention group experienced significant improvement of medication adherence (p = 0,006 for Group 1 и 2) vs control.
CONCLUSION. Secondary prevention methods with remote support improve the medication adherence in AF pts after CA which may positively affect on their health.
Individual Muscle Groups Performance Capacity Features and Presence of Functional Asymmetries in Сross-Country Skiers and Runners: an Original Article
Authors: Fedulova Daria V. , Berdyugin Kirill A.
Published: September 2023

INTRODUCTION. Each sport, given the regularity of the training activity, affects the development of the musculoskeletal system and the muscular system and may cause functional motor asymmetries. Cyclical sports based on the repetition of the motor action, while forming the dominant side of the body for the successful implementation of a motor act, can be prerequisites for the development of an imbalance in muscle work and the appearance of typical sports injuries and diseases. In view of these features, early diagnostics of athletes on the formation of motor asymmetries becomes relevant in order to assess their degree of influence on the work of the whole body, to create conditions and methodological basis for their correction.
AIM. To identify functional motor asymmetries in cross-country skiers and runners, to analyze the work of muscles in terms of their strength and endurance.
MATERIALS AND METHODS. The article analyzes the results of diagnostics of children aged 1213 years old involved in athletics (n = 17) and cross-country skiing (n = 18). Testing was carried out on the basis of the state autonomous institution of the Sverdlovsk region Adaptive Paralympic and Deaflympic Reserve Sports School (Yekaterinburg) on the Humac Norm (USA) multifunctional simulator. The muscles of the upper and lower extremities were studied in a concentric mode of operation.
RESULTS AND DISCUSSION. Motor asymmetries in hip flexion and extension muscles was revealed in cross-country skiers competing at 3 km and 5 km. Abduction and anterior thigh muscles were close to deficits. No asymmetric body work was detected in middle-distance runners. In terms of muscle strength and endurance, track and field athletes demonstrated higher performance in most of the studied muscles.
CONCLUSION. In the future, the study is planned to continue by supplementing the data with dynamic diagnostics, analysis of indicators of muscle use in running and walking, and correlation of values with isokinetic testing and postural diagnostics of visual impairments.

Authors: Kulchitskaya Detelina B. , Yurova Olga V. , Sevriugina Olga A.
Published: September 2023

INTRODUCTION. In recent years, magnetic resonance imaging (MRI) has been increasingly used to diagnose early osteoarthritis (OA). Taking into account the fact that nowadays pharmacological agents are not effective enough and often lead to allergization of the body, there is a need to search for new non-drug methods of treatment of patients with knee joint OA that have proven effectiveness.
AIM. To analyze scientific evidence on the use of MRI as an objective method of assessing the effectiveness of medical rehabilitation of patients with knee OA.
MATERIALS AND METHODS. We searched for publications in the PEDro and PubMed for the period from 2000 to March 2023. Suitable articles were to reflect the use of MRI as a criterion for the effectiveness of medical rehabilitation in patients with OA of the knee joint.
RESULTS AND DISCUSSION. As a result of a search in electronic resources, the largest number of works on the subject under study was found in PubMed. According to the literature quantitative analysis, 7256 works were identified, which reflect the use of MRI in medical rehabilitation. The publications in which the effectiveness of medical rehabilitation of patients with knee OA was evaluated by researchers using MRI accounted for 2.5 % of the total number. Most of the publications were in international databases, while they were practically absent in the Russian ones.
CONCLUSION. Despite the scarce research on the matter, we can distinguish the following rehabilitation medicine methods with a proven effect on the ligamentous apparatus, cartilage and soft tissues of the knee joint in patients with OA, according to MRI data: shockwave therapy, physical therapy and ultrasound therapy. However, the need for further scientific research in this direction is obvious.

The article demonstrates the main problems of spatial development of the territory of Russia lying to the east of the Ural Mountains. The authors highlight the common features and peculiarities, especially socio-­economic development in the last 20–30 years, as well as the approaches to solving the existing problems. Among the significant ones the authors refer to the increasing fragmentation of the economic space of the territory in question, which is reflected in the weakening of intra-­regional economic ties. The approach to solving the problems proposed by the authors is to recreate inter-­regional value chains (social value) on a new qualitative basis. Its most important feature lies in the step-by-step implementation of measures and increments - from the revival (in the framework of cooperative relations) of interaction between the participants of inter-­regional chains to the formation of cluster-type structures within the framework of individual horizontal components of these chains. But none of the considered measures can be effectively implemented without an active regulatory role of the state due to the spatial features of the territory.

TRANSFORMATION OF THE GLOBAL US HEGEMONY UNDER THE RISE OF CHINA
Authors:   e Financial University under the Government of the Russian Federation, Ilyinsky Alexander I. , Magamedov Aleksandr S. ,   McKinsey & Company
Published: September 2023

The article examines the process of the decline of US currency hegemony and the growth of China’s financial power, including competition and cooperation of great powers facing many geopolitical problems. The United States still has significant military capability, technological innovation, and soft power, while China’s Belt and Road Initiative has expanded its economic power and influence in the Eurasian and African regions. The future of global hegemony depends on the interaction and relationship between these two powers, with risks and opportunities distributed unevenly between the existing great powers and the small/medium countries. Russia’s role in this transition is significant, and it must carefully strategize its approach, viewing its heavy reliance on energy exports as a potential vulnerability. To avoid risks and seize opportunities, Russia must take a balanced approach by diversifying its economic base, improving the investment climate, promoting innovation and technological advances, and actively participating in regional and international forums.

In these conditions, it is necessary to form a effective policy of adaptation, and then structural and technological restructuring of the Russian economy. The choice of economic policy directions is complicated both by the scale of the tasks facing the Russian economy and by the processes of changing the global model of trade and economic relations.
