Nonlinear system identification via sparse Bayesian regression based on collaborative neurodynamic optimization
Authors: Okunev Alexey , Burnaev Evgeny
Published: August 2024

Sparse identification of nonlinear dynamics is a popular approach to system identification. In this approach system identification is reformulated as a sparse regression problem, and the use of a good sparse regression method is crucial. Sparse Bayesian learning based on collaborative neurodynamic optimization is a recent method that consistently produces high-quality solutions. In this article, we extensively assess how this method performs for ordinary differential equation identification. We find that it works very well compared with sparse regression algorithms currently used for this task in terms of the tradeoff between the approximation accuracy and the complexity of the identified system. We also propose a way to substantially reduce the computational complexity of this algorithm compared with its original implementation, thus making it even more practical.
Experimental analysis of failure modes depending on different loading conditions applied on cylindrical polyamide 66 gears
Authors: Hriberšek Matija , Kulovec Simon
Published: August 2024

Engineering plastics are increasingly used for gearing systems, such as in the automotive sector, e-mobility sector, and household appliances. The basic task of the gearing system is to efficiently transfer power from the source to the application user. The use of engineering plastics for gearing applications is conditioned by the lack of tribological characteristics of material pairs which influence on fatigue and wear behaviour of the whole gearing system. The paper presents testing of the steel/Polyamide 66-gear by determining fatigue life in an infinite area, considering high precision optical measurements in the range of micro-meter accuracy of abrasion flank wear together with surface temperature in contact, providing an important database for engineers about material suitability for appropriate mechanical systems. Observing the results, gear flank wear of PA66 HT is directly proportional to the meshing temperature and torque. Thermal melting is a characteristic failure mode of the polymer gears which are exposed to higher load levels. In the middle torques, the dominant failure mode is flank fracture known as pitch point fracture. The greater impact of the gear wear mechanism occurs at lower torques where initial crack propagation starts at the pitch point and ends in the tooth root area.

Published: August 2024

Concurrent engineering, focused on efficient process management, is intertwined with quality management in a project whose objective is to develop a methodology to integrate both disciplines through the structuring of divergent and flexible processes. This approach is applied in a case study on the manufacturing of sustainable street furniture on a laboratory scale. To this end, three stages were established that allowed the identification of the processes with their inputs and outputs and the generation of the synergies necessary for their integration. This methodology demonstrated its effectiveness by building products on a laboratory scale, optimizing and streamlining production. In addition, it opens the opportunity to apply it in larger scale processes. The importance lies in its ability to improve efficiency in product development, highlighting interdisciplinary collaboration and providing an approach applicable to the sustainable production of street furniture.

The current state of the temperature and humidity regime of the territory of Ukraine from 1991 to the present time under the influence of changes in large-scale atmospheric circulation is considered. The atmospheric circulation model by V. Martazinova and the EOF decomposition of pressure fields, the beginning of the formation of the modern climate regime since 2006 was determined. For the analysis of the modern temperature-humidity regime, the data of the fields of air temperature, atmospheric precipitation, pressure, geopotential in the nodes of the geographic grid of the Atlantic-European sector of the archive of UkrGMI-СDDPP; NOAA Northern Hemisphere Archive; air temperature, precipitation, direct solar radiation of Ukrainian stations since 1991 were used. It is established that the temperature since the beginning of our century on the territory of Ukraine is growing, dry processes with deficit of precipitation are observed in April, August and September. The increase of the drought processes affects the current state of direct solar radiation, which for the warm period of the last 15 years exceeds the norm of previous years almost in all territory of Ukraine, especially in the northern and central regions.

The most reliable forecasts can be obtained for hydrogeological objects that have signs of determinism in regime changes. First of all, these include systems with an undisturbed mode. However in the network of state hydrogeological monitoring of groundwater, there are no objects with an undisturbed regime due to the spread of direct anthropogenic influence and indirect - due to the changes in climatic conditions caused by it. Significant variability and unpredictability of changes in traditional regime-forming factors (air temperature and precipitation) over the last decades proves the low efficiency of forecasting the level and flow of groundwater using empirical regression equations built on data from the 1980s - early 2000s. It was possible to obtain more reliable results with the help of neural network modelling, which involves working with significant series of contradictory data that change according to an unknown algorithm. The forecast was made for the specific underground flow to the South Bug River in the area of Khmilnyk. The advantages of simulated forecasting over time series forecasting are shown.

Drought is a dangerous natural phenomenon that has often been observed during the last thirty years. In certain months of the cold period of the year, droughts were observed at the end of autumn (November), at the end of winter and at the beginning of spring (February-March). The purpose of the work is to evaluate the changes in the components of the radiation regime of solar radiation during droughts or their prerequisites for the cold period of the year in 1991-2020 in Ukraine. During some cold periods, the prerequisites for the development of droughts were noted. The latest in the cold period of the year are droughts or the prerequisites for them, in particular some in the larger territory of Ukraine, which are caused by a special state of the atmosphere with the anticyclonic nature of the atmospheric circulation and the transformation of slow-moving air masses in large areas. According to a complex of dynamic processes that cause the development of this phenomenon, there is an increase in the duration of sunlight and short-wave radiation, which leads to an increase in air temperature during a period without rain or precipitation. In the conditions of changes in atmospheric circulation in 1990-2020 relative to 1961-1990, which led to an increase in clear and cloudless weather, deviations of individual components of the radiation regime of solar radiation were observed in certain months of the cold period. In the cold period of the last three decades, during droughts or the conditions for them, an increase in the duration of sunshine, the flow of direct and total solar radiation was observed, which was accompanied by a decrease in scattered radiation. The set of dynamic processes during droughts or the prerequisites for them leads to an increase in the energy potential of the active surface. Changes in the components of the radiation regime of solar radiation during droughts or prerequisites for them during the cold period of the year and their comparison relative to the average values for the years 1991-2020 in Ukraine are given. The conducted studies are important in the direction of monitoring climate change anomalies, which determine the solution of applied problems of adaptation of agricultural production in conditions of droughts or prerequisites for them during the cold period.
LOGICAL-APRIORI ANALYSIS IN HYDROGEOLOGICAL RESEARCH
Authors: Shevchenko O. ,   Ukrainian Hydrometeorological Institute of the State Emergency Service of Ukraine and the National Academy of Sciences of Ukraine, Kyiv, Ukraine
Published: August 2024

The article demonstrates with examples that due to the lack of input information, logical a priori analysis can be effectively applied to solve not too complex hydrogeological problems: in regional studies, for the analysis of observation data on the groundwater regime, in the design of underground water intakes, dissection of river hydrographs, selection calculation parameters for modeling, etc. Nowadays, this method of analysis is replaced by methods of information processing using artificial intelligence, which does not require deep knowledge of the subject and significant experience of the researcher. It is shown that the logical a priori analysis can be an effective auxiliary method when performing hydrodynamic calculations. Thus, with its help, it was found that the most representative parameter, which manifests and controls the dependence of the groundwater recharge on precipitation, is the weighted average annual coefficient of infiltration recharge. This indicator can also be used to correct unknown filtering parameters, since it has a narrow range of variability, which in turn is controlled by the actual amount of annual precipitation.

The full-scale russian invasion of Ukraine significantly changed atmospheric air pollution in Ukrainian cities. Most changes can be identified using only remote sensing data due to its spatial coverage. In the presented paper, we perform the analysis of war impacts on nitrogen dioxide (NO2) and carbon monoxide (CO) spatial distribution derived from the TROPOsphericMOnitoring Instrument (TROPOMI) of the Sentinel-5 Precursor (S5P) satellite data for the period of January 2021 – May 2023. Based on their content in polluted plumes over the city and in the background, the parameter dNO2/dСО for burning efficiency assessment was calculated and processed. The overall decrease in NO2 and CO content was detected in the cities, reaching 6-34% and 9-17%, respectively. In comparison to background content, the NO2 drop in cities was more significant. At the same time, CO decreased by 2-3% more in the background than over the cities (except Mariupol, where Azovstal was totally destroyed). Since the full-scale hostilities have started, total NO2 content began redistributing seasonally and its summer maxima started to appear in the majority of cities. Starting from the period of regular drone and missile attacks on energy infrastructure, background NO2 significantly decreased, showing a regional response. CO total content has changed mostly homogeneously over the entire studied domain. There were no seasonal shifts or dependencies during the period of war. Using the four parameters mentioned, we estimated burning efficiency changes based on the dNO2/dСО parameter. It allowed us to detect possible changes in fuel use. Overall, dNO2/dСО decreased by 11-46% which indirectly proved the increase in solid or “dirty” fuel use and less gas consumption. Burning efficiency dropped immediately after the full-scale invasion started, becoming more sensitive to pollutants content in the plume. The consideration of the researched parameters is important for making new atmospheric air quality management plans in cities, rebuilding damaged infrastructure, and creating emission inventories during the wartime.

The first article in a series of analyses on changes in thermal periods in Ukraine until the end of the 21st century is presented here. It focuses on analyzing the characteristics of the warm period, defined by a persistent transition of the average daily temperature above 0°C, separating it from the winter period. With the improvement in the spatial resolution of regional climate models (RCMs) and the updating of scenarios, there is a need to refine the characteristics of the warm period, crucial especially for agriculture and forestry. Based on data from the E-Obs database, the start dates, end dates, and duration of the warm period in Ukraine during the standard climatic period of 1961-1990 were analyzed, along with changes in these characteristics further in 1991-2010. An assessment of changes in values for future periods 2021-2040, 2041-2060, and 2081-2100 was also conducted using scenarios of representative concentration pathways (RCP 4.5 and RCP 8.5) with an ensemble of 34 RCMs from the Euro-CORDEX project with a spatial grid resolution of approximately 12×12 km. It's worth noting that previous studies by other authors have already assessed changes in the characteristics of the warm period, but using previous A1B scenarios and a much smaller number of RCMs characterized by a coarser grid of 25×25 km. According to updated climate scenarios, the duration of the warm season in the 21st century will increase across the entire territory of Ukraine, with more pronounced changes expected in the north and east. Under RCP 4.5 and RCP 8.5 scenarios, an increase in the duration of the warm period is projected in 2021-2040 relative to 1991-2010: from 7-14 days in the south to 20-23 days in the north and east of Ukraine. In the period 2041-2060, under RCP 4.5, changes will range from 7 days in the south, Transcarpathia, and the Carpathians to 20-25 days in the northeast, while under RCP 8.5, changes will range from 7-14 to 30-35 days, respectively. By the end of the century, these changes will continue, and in Crimea, there is a high likelihood that temperatures will not drop below 0°C, meaning there will be no winter season. Analysis of other thermal periods will be presented in subsequent parts of the study.
MODERN WATER CONFLICTS AND CONFRONTATIONS (HYDROGEOLOGICAL ASPECT)
Authors: Shevchenko O. ,   Ukrainian Hydrometeorological Institute, Kyiv
Published: August 2024

The article discusses ambiguous, controversial decisions and cases of handling water resources in Ukraine and on the border territory of neighboring states. These are situations in which the water environment (water bodies) becomes an obstacle, a victim, a resource, a means of pressure, and sometimes a weapon for various participants. In wartime, water resources are used by aggressors as a weapon, including as a means of putting pressure on the population by depriving them of the necessary means of subsistence. It is shown that in democratic states, in the presence of corruption in the field of water resources management, any solutions are possible, if the propaganda company is directed accordingly. The article highlights six categories of narratives that distort the real situation and are designed to impose on society a certain decision regarding the treatment of a water body that is beneficial to one of the parties to the conflict or the beneficiary. Examples of these categories from the events of recent decades are given: the E40 waterway, the Khotyslavskyi quarry, the Kakhovs’kyi reservoir, water supply of Crimea, which is still occupied by russia, etc. Hydrogeological aspects are mostly discussed. From a comparison of a number of contradictory factors for and against the restoration of the Kakhovs’kyi reservoir, restoration is more appropriate. In the absence of a reservoir, the safe operation of Zaporizhzhya NPP even at 50% of maximum capacity becomes problematic. It is emphasized that in disputed situations, balanced decisions should be made based on the expert assessments of at least three parties: two participants in the dispute and an independent party, with the limitation of biased non-professional assessments in favor of one of the parties and the exposure of falsifications. For this, it is necessary to train specialists capable of objectively evaluating such controversial situations, and society should be educated on the priorities of 'environmentalism', rational use of resources and far-sighted benefits for the country.

Published: August 2024

Epigenetics, one of the most rapidly intensifying fields of biological research and this field has experienced remarkable research attention in recent years, yet few studies investigated a bibliometric analysis of epigenetics research. In this research, the article analysed the provides a comprehensive overview of literature on epigenetics published between 2012 and 2021.

 The Web of Science Core Collection Database was used to retrieve all related publications. The search was conducted on September 20th, 2023 and select articles or reviews as the document type which resulted in 9,677 publications. The scientometric tools were applied to collect information on publications years of these papers, most prolific authors, famous journals, most productive countries and organizations, language and subjects.

 A total of 9,677 publications were retrieved. The publication's output showed a gradual upward trend from 2012 to 2021. The highest number of publications was 1,183 published in 2021. In our study, 117 countries contributed to this area of research in total. The top three countries were the USA, China, and Germany. Proceedings of the National Academy of Sciences of the United States of America was the journal with the highest production. Zhang Y is the most productive author with 65 (0.67%) publications. The 9,677 epigenetics articles were published by 8,145 different authoring organizations. University of Michigan is the institution where the most research related to epigenetics analysis has been developed, with 141 publications.

 Epigenetics is an emerging area of scientific research. However, most scientific research is conducted in environmental influences and relatively few are on human models. Analysis of the academic communities performing epigenetics research may provide scientific evidence. The method proposed in this research can provide reference for future bibliometric studies.

Advancement and development in a particular area of research are illustrated by the ever-growing body of scientific literature. This accumulation of literature describes various developments and innovations that occur over time and contains potentially valuable information that can be evaluated and classified to explain current emerging trends. In this study, we present a scientometric analysis of the retrieved papers published between 2012 and 2021 in the field of Epigenetics. Since 2012, the number of publications related to this field has grown rapidly. The United States and China are at the fore-front of Epigenetics research and the cooperation between these two countries is relatively close. In this research field, most productive institutes and authors come from United States and China, and the high frequency of Biochemistry and Molecular Biology shows that they are hot subjects.

Los sistemas de georadar se constituyen en una herramienta geofísica que cada vez tiene mayores aplicaciones dentro de las geociencias. Desde hace algunos años, la glaciología ha hecho uso de dicha técnica para definir contactos hielo-roca en diferentes masas glaciares del mundo. Se relacionan dos ejemplos de su aplicación en Sudamérica en busca de estimar espesores de hielo en volcanes nevados para propósitos de mapas de amenazas volcánicas y estudios de paleoclima. El primer caso hace alusión al levantamiento de 2567 m lineales de perfil sobre cuatro cuencas glaciares del Volcán Nevado del Ruiz (Colombia); estos registros permitieron establecer una definición preliminar de la morfología del estrato rocoso, donde el máximo espesor de glaciar hallado (190 m) se localiza sobre el glaciar Nereidas (5240 msnm). El análisis de dichos perfiles permitió además la identificación de una estructura volcánica desconocida hasta la fecha y que podría ser una caldera de importante tamaño localizada en la zona del glaciar Nereidas en dirección al cráter Arenas. El segundo caso permite registrar las masas glaciales actuales en el marco de los estudios de avance y retroceso glaciar en el Volcán Antizana (Ecuador) en un intento por entender en un futuro cercano la dinámica de El Niño en los últimos 10.000 años.

LAS CALIZAS DE TETUAN: UNA NUEVA UNIDAD LITOESTRATIGRAFICA PARA LA SUBCUENCA DE NEIVA, VALLE SUPERIOR DEL MAGDALENA. ESTRATIGRAFíA, PETROGRAFíA Y AMBIENTE SEDIMENTARIO
Authors: Peña John J. , Annicchiarico Giovanni P. , Jaramillo José M. , Velásquez Enrique
Published: August 2024

Se propone formalmente el término Calizas de Tetuán para designar la parte inferior del Grupo Villeta en la Subcuenca de Neiva. El intervalo litoestratigráfico se define a partir de sucesiones aflorantes en las quebradas El 9cal, ltaibe y El Tobo, donde se establecen tres segmentos (I, II y III) correlacionables simultáneamente con cuatro segmentos (A, B, C y D) definidos en subsuelo mediante registros eléctricos. Los aspectos regionales de la unidad son documentados con un mapa y cuatro secciones de correlación. Se propone un ambiente sedimentario de plataforma carbonatada abierta (tipo rampa), inundada por aguas cálidas y desarrollada durante un ciclo transgresivo del Albiano medio al superior, sobre una cuenca pericratónica.
ALGUNOS ASPECTOS DE ECOLOGÍA QUÍMICA DE LAS ESPONJAS DEL CARIBE AXINYSSA AMBROSIA Y APLYSINA INSULARIS
Authors: Puyana Mónica , Petrichtcheva Natalia Victorovna , Morales Alicia Lucía , Duque Carmenza , Zea Sven
Published: August 2024

El compuesto clorhidrato de axinyssamina (compuesto 1) se encuentra en la esponja Axinyssa ambrosía en concentraciones del orden de 10 mg/mL. Mediante ensayos con el coral Madracis mirabilis se encontró que este compuesto es letal para los pólipos del coral a la concentración natural que se encuentra en la esponja. Adicionalmente, se hicieron ensayos de exudación en acuario logrando determinar por CGAR-EM (modo sean y sim) que los compuestos 11-formamida-7β-H-eudesm-5-eno (2) y 4α-formamidogorgon-11-eno (3) que se encuentran en el cuerpo de esta esponja, se exudan continuamente formando una barrera química protectora. La tasa de exudación de estos compuestos aumenta 3.80 y 2.47 veces respectivamente bajo condiciones de estrés o agresión. Estos resultados permiten suponer que Axinyssa ambrosía puede usar estos tres metabolitos como defensa química.De otra parte, se realizaron experimentos con Aplysina insularis, in situ, con el fin de detectar cambios en su composición química (metabolitos bromados) mediante análisis por CL-EM, durante intervalos de tiempo variables después de causar heridas en su superficie. No se obtuvo evidencia de transformaciones químicas como consecuencia de daños en el tejido de las esponjas. Tanto en experimentos a corto (2.5 minutos) como a largo plazo (120 minutos), bajo condiciones ecológicamente relevantes, la conversión de los compuestos mayoritarios de alto peso molecular en los compuestos de bajo peso molecular aeroplisinina-1 (4) y/o la dibromociclohexadienona (5) no fue aparente. Estos resultados sugieren que la transformación de metabolitos bromados de alto peso molecular en otros con mayor capacidad defensiva que sus precursores no ocurre en Aplysina insularis como mecanismo de defensa.

Published: August 2024

El delfín rosado del género Inia es endémico de las mayores cuencas hidrográficas del norte de Sudamérica. Este trabajo constituye el primero a nivel mundial que pretende dar aproximaciones acerca de la estructura genética de este género. Se colectaron 96 muestras de especímenes en las cuencas de los ríos Orinoco, Putumayo (400 km de recorrido) y en los ríos Mamoré, Ipurupuru y Tijamuchi en la Amazonia boliviana y se incluyeron 5 muestras de la Amazonia brasileña. Se estudiaron 570 pb de la región d-loop del ADN mitocondrial y 600 pb del gen citocromo b. Los análisis filogenéticos y de subdivisión poblacional soportan la propuesta de dividir el género en dos especies filogenéticas, y revelan aspectos importantes acerca de la estructura genética de los grupos de Inia en estas regiones geográficamente separadas.

Habitação mínima contemporânea: estudo de caso do apartamento de 10 metros quadrados
Authors: Oliveira Filho Marco Antônio Martins de , Perrone Rafael Antônio Cunha , Silva Julia Rodrigues da
Published: August 2024

A produção de habitação mínima contemporânea ganha força no mercado imobiliário paulistano a partir do começo do século XXI. A chegada de apartamentos denominados estúdios, com metragens entre 15 a 20 metros quadrados, está presente na grande maioria dos novos edifícios comercializados na contemporaneidade, especialmente aqueles localizados próximos a serviços de mobilidade urbana de massa. No entanto, um produto imobiliário ganhou atenção não só do mercado, mas também dos arquitetos e da sociedade civil. Apartamentos de 10 metros quadrados foram lançados para a comercialização na cidade de São Paulo se enquadrando como os menores apartamentos da América Latina. O objetivo central do trabalho busca entender como foi possível a sua aprovação legal, as condicionantes socioculturais capazes de gerar uma habitação tão reduzida e o desempenho dessa habitação a partir de conceitos qualificadores como uso, ergonomia e conforto. Nesse contexto, o estudo versa sobre a sua importância prática ao tentar estimular o debate sobre os apartamentos mínimos e o impacto dessa arquitetura, dialogando com a sua performance e usabilidade entre morador e obra arquitetônica. O trabalho possui a metodologia exploratória, a partir de busca referencias teóricos, e explicativa, pois identifica as causas dos fenômenos estudados, além de registrar e analisar os rebatimentos disso nos apartamentos mínimos.  O estudo tem o intuito de diagnosticar a produção arquitetônica contemporânea e a qualidade de vida em que esses espaços podem oferecer nas novas formas de habitar.
