An improved unbiased particle filter
Authors: Jasra Ajay , Maama Mohamed , Ombao Hernando
Published: December 2023

In this paper, we consider the filtering of partially observed multi-dimensional diffusion processes that are observed regularly at discrete times.
We assume that, for numerical reasons, one has to time-discretize the diffusion process, which typically leads to filtering that is subject to discretization bias.
The approach in [A. Jasra, K. J. H. Law and F. Yu,
Unbiased filtering of a class of partially observed diffusions,
Adv. Appl. Probab.
54 (2022), 3, 661–687] establishes that, when only having access to the time discretized diffusion, it is possible to remove the discretization bias with an estimator of finite variance.
We improve on this method by introducing a modified estimator based on the recent work [A. Jasra, M. Maama and H. Ombao,
Antithetic multilevel particle filters, preprint (2023), https://arxiv.org/abs/2301.12371].
We show that this new estimator is unbiased and has finite variance.
Moreover, we conjecture and verify in numerical simulations that substantial gains are obtained.
That is, for a given mean square error (MSE) and a particular class of multi-dimensional diffusion, the cost to achieve the said MSE falls.

Published: December 2023

This article deals with volatile organic substances (VOCs) and odours that can be released into the indoor environment from synthetic leathers that are part of upholstered furniture. The primary task of this study was to provide a detailed analysis of selected synthetic leathers and assess their emission characteristics, including odour substances. VOC emissions were determined using the test chamber method (ČSN EN ISO 16000-9) at a temperature of 23°C and a relative humidity of 50%. The emitted compounds were adsorbed by standard stainless steel tubes with Tenax TA sorbent. VOCs were analysed by thermal desorption and gas chromatography with mass spectrometry The properties of odours were tested using a Sniffer 9000 device, which was directly connected to a gas chromatograph with a flame ionization detector. The dominant substances (with the highest concentration) that were emitted by samples of tested synthetic leathers include toluene (118.2 µg·m−3), 1,2-propanediol (46.2 µg·m−3), and limonene (153.0 µg·m−3). Ohio synthetic leather produced the most unpleasantness hedonic tone (-4) from all evaluated materials.

Experiencing virtual reality and visual memory
Authors:   Uniwersytet Mikołaja Kopernika w Toruniu, Majewska Kamila
Published: December 2023

The number of studies investigating different aspects of the use of virtual reality and VR goggles is constantly growing. However, there is currently a lack of analyses related to the visual memory of resources learned in immersive VR. Therefore, a study was conducted to determine the level of memorisation of visual elements presented using VR headsets or a traditional computer. The study involved 120 students divided into three equal groups. In the first group, the participants used VR goggles and the presentation was supervised by a lecturer who drew attention to key elements and monitored the pace of the action. In the second group, users worked entirely on their own with the VR headsets, and in the third group they watched a narrated presentation on a computer screen. The main research objective was to determine the differences in the amount of elements memorised between the study groups. The study used both quantitative and qualitative data. The ANOVA analysis of variance showed that there was a statistically significant difference between all groups. The highest level of memorisation of visual elements was recorded in the group using VR goggles and supervised by a guide. The lowest was in the group that used VR headsets alone. Participants in the study noted that immersive VR is so fascinating that it is difficult for them to supervise their own time and activity in a way that ensures success. As a result, 70% of people working alone with VR goggles did not manage to familiarise themselves with all the material.

Published: December 2023

Mentoring, which is increasingly used in the development of professional competences, is rarely analysed in terms of managerial roles and gender. Simultaneously, women in managerial roles increasingly reveal high levels of effectiveness in the business environment. The aim of this article is to diagnose the range and diversity of mentoring experienced by Polish female managers, including two types of mentoring: career and psychosocial. The research involved 370 women who hold managerial positions in organisations located in Poland and who have experience of participating in a mentoring relationship. A quantitative method was used using the Global Measurement of Mentoring Practices questionnaire and the CAWI technique. Student’s t-tests and one-way ANOVA preceded by Levene’s tests of variance were conducted. It has been demonstrated that the career paths of the surveyed female managers were significantly supported by the activities of the mentor. The extent of psychosocial support was found to be greater than of professional support. In terms of psychosocial mentoring, top-level female managers received the greatest extent of support, and in terms of career mentoring, those whose relationship with a mentor was both formal and informal and varied by the gender of the mentor. The findings presented here may be useful in improving mentoring programmes targeted at female managers.
Intranasal Delivery of Ketamine Induces Cortical Disinhibition
Authors: Qiao Xin , Grieco Steven F. , Yu Zhaoxia , Holmes Todd C. , Xu Xiangmin
Published: December 2023

Our previous studies find that subcutaneously administered (s.c.) subanesthetic ketamine promotes sustained cortical disinhibition and plasticity in adult mouse binocular visual cortex (bV1). We hypothesized that intranasal delivery (i.n.) of subanesthetic ketamine may have similar actions. To test this, we delivered ketamine (10 mg/kg, i.n.) to adult mice and then recorded excitatory pyramidal neurons or PV+ interneurons in L2/3 of bV1 slices. In pyramidal neurons the baseline IPSC amplitudes from mice treated with ketamine are significantly weaker than those in control mice. Acute bath application of neuregulin-1 (NRG1) to cortical slices increases these IPSC amplitudes in mice treated with ketamine but not in controls. In PV+ interneurons, the baseline EPSC amplitudes from mice treated with ketamine are significantly weaker than those in control mice. Acute bath application of NRG1 to cortical slices increases these EPSC amplitudes in mice treated with ketamine but not in controls. We also found that mice treated with ketamine exhibit increased pCREB staining in L2/3 of bV1. Together, our results show that a single intranasal delivery of ketamine reduces PV+ interneuron excitation and reduces pyramidal neuron inhibition and that these effects are acutely reversed by NRG1. These results are significant as they show that intranasal delivery of ketamine induces cortical disinhibition, which has implications for the treatment of psychiatric, neurologic, and ophthalmic disorders.
Biogeochemical effects of a forest understory plant invasion depend more on dissimilar nutrient economies than invader biomass

Published: December 2023

There is increasing need to better understand how and why invasion impacts on biogeochemical cycling differ across heterogeneous landscapes. One hypothesis predicts invader impacts are greatest, where the invader is most abundant (the mass ratio hypothesis; MRH). Alternatively, invader impacts may be greatest in communities, where the nutrient acquisition strategies of the invader are most dissimilar from those of native species (the nutrient economy dissimilarity hypothesis; NEDH). We tested whether the impact of an invasive grass, Microstegium vimineum, on soil biogeochemistry could be better explained by MRH, NEDH, or both. Invaded and reference study plots were established at 3 locations (Indiana, North Carolina, and Georgia) that varied in the relative abundance of arbuscular mycorrhizal (AM) versus ectomycorrhizal (ECM) associated overstory trees (across a nutrient economy gradient), reflecting gradients in biotic nutrient acquisition strategies and edaphic factors. At 2 locations, we found a proxy for NEDH explained invader effects on soil conditions and the net effect of M. vimineum was to homogenize soil properties across the nutrient economy gradient toward conditions consistent with AM-dominated stands. At the third location, both ECM-dominance (NEDH) and invader biomass (MRH) predicted differences in soil moisture, pH, and nitrification rates with may be related to the high N availability and intermediate acidity at this location. Collectively, these results suggest the biogeochemical consequences of M. vimineum depend, in part, on preinvasion soil nutrient economies. Where preinvasion conditions are known, we provide a scalable and predictive approach to determine where impacts on biogeochemical cycling of C and N may be greatest.
El concepto de persona en “Introducción al cristianismo” de Joseph Ratzinger
Authors: Del Hierro Dies Josep
Published: December 2023

Se investiga una aproximación a la definición de persona que propone Joseph Ratzinger en “Introducción al cristianismo”. Aunque el concepto de persona no está expuesto de manera sistemática y ordenada en el libro, sin embargo, tras un estudio atento, se percibe en él una idea clara de lo que éste significa. Así pues, después de una breve introducción, se aborda el tema de la antropología de Joseph Ratzinger como requisito previo a la noción de persona. Se sigue con una sistematización de este concepto. Posteriormente, se aborda la relación entre persona y dignidad. A continuación, se desvela el vínculo entre cada una de las partes del Credo con el concepto persona —pues tiene en la fe cristiana su principal fundamento significativo—. Finalmente, se propone una definición de persona acorde con el pensamiento de Joseph Ratzinger en el año 1968: relación íntima de verdad y amor.

Published: December 2023

En 1638 llegan al puerto de Alicante más de 300 piezas de jaspe procedente de Tortosa con destino al Palacio del Buen Retiro de Madrid, pero los jaspes quedaron abandonados en el puerto. En 1657, la ciudad de Alicante solicita algunas piezas para su iglesia mayor, el Consejo de Aragón decide destinar diferentes partes a la obra del Hospital de la Corona de Aragón, la capilla de San Isidro en la iglesia de San Andrés y las iglesias de Orihuela y Alicante. El puerto de Alicante era lugar tradicional de desembarco de obras de arte y materiales de construcción, entre ellos se encuentra el jaspe de Tortosa utilizado con profusión en la arquitectura hispana a principios del siglo XVII. El envío a Alicante coincide con los intentos de transformar la fachada del palacio.

En este artículo llevo a cabo un estudio de la representación del paisaje en del "Voyage Pittoresque et Historique de l'Espagne" (1806-1820) de Alexandrede Laborde (1773-1842). Laborde contó para realizar las ilustraciones de esta obra con un nutrido grupo de dibujantes, entre los que destacan Jacques Moulinier, François Ligier, Dutailly, Jean-Lubin Vauzelle y Constant Bourgeois. Los diferentes apartados del artículo están organizados con la finalidad de ir presentado al lector el universo de ideas y de prácticas artísticas que se hallan en la base de las composiciones del paisaje del "Voyage". La primera cuestión examinada son los diferentes sentidos de la noción de lo pintoresco, y el modo en que esta noción se adaptaba perfectamente a la diversidad de funciones propia de las publicaciones de "viajes pintorescos". A partir de aquí, examinando los dibujos, los grabados y el texto del "Voyage", voy desgranando los modelos artísticos, las técnicas de representación, y el transfondo literario y filosófico que se halla en el origen de estas imágenes, es decir el mundo de referencias que conforman el sistema de interpretación del paisaje puesto en práctica por los ilustradores del equipo de Laborde para realizar sus composiciones del paisaje peninsular.
Andrés de Leito: revisión pictórica
Authors: Collar de Cáceres Fernando
Published: December 2023

Andrés Deleito (de Leito) es artista relacionado en esencia con la pintura de naturalezas muertas y con la "vanitas". La incorporación al catálogo de su obra de diversas creaciones de temática religiosa, entre ellas una "Anunciación" firmada, mueve a redefinir su perfil artístico en la escuela madrileña de la segunda mitad del siglo XVII. La revisión de su obra pictórica, con el análisis de sus recursos compositivos y estilísticos, lleva también a atribuirle algunos nuevos bodegones así como una "Vanitas" tenida hasta ahora por obra de Antonio de Pereda.

Esculturas de humo: chimeneas y caños del Renacimiento en la Alta Extremadura
Authors: Sanz Fernández Francisco
Published: December 2023

Uno de los aspectos más singulares del paisaje urbano y arquitectónico de la Alta Extremadura durante el Renacimiento fue el de sus chimeneas y esculturas de humo, que coronaban por doquier los aleros y tejados de arquitecturas residenciales, ya fuesen palacios nobiliarios o de jerarcas de la iglesia, ya villas suburbanas y campestres, centros monásticos o viviendas populares. Edificios capitales del paisaje urbano renacentista extremeño como el palacio Episcopal de Plasencia, el Real Monasterio de Guadalupe o las casas principales de los Carvajal Vargas en Trujillo, se destacaban entonces en el entorno mediato y lejano gracias a una suerte de hitos urbanos de fábrica de ladrillo decorada con todo tipo de ornatos esgrafiados sobre un mortero de cal. Estas esculturas urbanas compendian, mejor que otras muchas partes de aquella arquitectura, la riqueza ornamental y los acabados característicos de nuestro Renacimiento. También la diversidad de influencias y fuentes de que bebieron y fueron objeto nuestros arquitectos aquellos siglos. La huella del mudéjar, el influjo franco-flamenco, el ornato y las formas italianas se suman para generar unas estructuras únicas y sincréticas, en las que no es difícil recordar los modelos recogidos en sus respectivos tratados de arquitectura por Sebastián Serlio y Cesáreo Caesarino o los tipos diseñados por los artífices de las techumbres de los Reales Sitios durante el reinado de Felipe II.
Los biombos tagasode: Claves literarias e históricas para su interpretación
Authors: Sastre de la Vega Daniel
Published: December 2023

Los biombos japoneses tagasode del periodo Momoyama (1573-1615) y de principios del periodo Edo (1615-1868) constituyen dentro de la historia del arte japonés uno de los mejores ejemplos para comprender como los contextos sociales de producción de una obra de arte alteran la recepción de dicha obra. Asimismo, sobrepasan la barrera social y construyen un discurso en el que el género emplaza su instrumentalización y re-contextualiza su entendimiento. Frente a su análisis desde lo formal que ha venido emplazando estas obras como un eslabón más dentro de la evolución de la pintura de género, este artículo introduce la singuralidad de estas obras mediante el estudio de costumbres decorativas asociadas a grupos sociales específicos. Hasta la fecha, dos son las principales explicaciones que los especialistas han barajado: una primera, más tradicional, que sostiene que lo representado en los biombos se inspira en la literatura, mientras una segunda y más reciente tesis, defendida por los historiadores del mueble y del vestido, pone el hincapié sobre el carácter funcional del biombo y su instrumentalización.
Isidoro de Tapia (hacia 1712- activo hasta 1771/1777), pintor rococó de la Academia de San Fernando de Madrid
Authors: Gutiérrez Pastor Ismael
Published: December 2023

El pintor Isidoro de Tapia es un ejemplo de la compleja situación de la pintura en la España del siglo XVIII. Su formación en la tradición artística barroca de Valencia se transformó cuando se trasladó a Madrid, donde ingresó en la Academia de San Fernando y trabajó al servicio de las Reales Caballerizas del Palacio Real. Se reconstruye su vida a partir de documentos conocidos e inéditos, interpretados en un contexto amplio. Unas pocas pinturas firmadas sirven para agrupar otras de estilo semejante y construir un pequeño catálogo de veintiocho obras que reafirma la personalidad del pintor frente a los otros contemporáneos a quienes se les han atribuido.
Crustal and Lithospheric Variations along the Western Passive Continental Margin of the Indian Peninsula
Authors: Prasad Muthyala , Dubey Chandra P.
Published: December 2023

The western passive continental margin (WPCM) of the Indian Peninsula is one of the world's largest and most remarkable escarpments, signifying a boundary between oceanic and continental lithospheres. It traverses distinct lithological units, majorly the SGT, WDC, and DVP, each characterized by distinct geological structures, geochronological histories, and petro-physical properties. Despite numerous research efforts, the exact mechanisms governing the WPCM evolution and its developmental connections remain unclear due to limited data and significant uncertainties. In our study, we meticulously analyzed global and local models, focusing on the Western Ghats (WG), to examine crust and lithosphere thickness. Our analysis revealed significant uncertainties in crustal and lithospheric variations, with a maximum difference of 10.68% in crust thickness and 20.04% in lithospheric thickness across different major lithological formations in the WG. These differences can have a substantial impact on the geodynamic analysis of lithospheric structures and tectonic evolution. Additionally, we developed a 2-D lithospheric density model over the WG, crossing the major geological units, which delineates the crust and lithospheric structure between the eastern and western sides of the escarpment. Our results, in conjunction with geomorphological data, suggest that the WPCM’s thick lithosphere with elevated topography illustrates a continuous upwarp, supported by flexural compensation of uplifted terrain. The movement of the Indian plate, primarily in the N-S and NW-SE directions, subsequently modified the entire escarpment. This model offers insights into the evolution of the WPCM and potentially contributes to the formation of the NE-SW fault in the southern part of the South Indian Shield, with potential implications for the Palghat gap.
Current and Perspective Approaches to the Treatment of Prolactinomas
Authors: Barabash Nadiya , Tykhonova Tetiana , Kanishcheva Olena
Published: December 2023

Background: Along with the presence of the 2011 Endocrine Society Clinical Practice Guidelines and numerous large-scale studies on the treatment of hyperprolactinemia of different origin, there are some unresolved questions, ambiguous and sometimes contradictory points of view regarding the management of patients with prolactinomas. This overview is devoted to the analysis of the results of modern clinical studies and the approaches towards the management of hyperprolactinemia caused by prolactinoma.Materials and methods: A systematic research of the literature for the appropriate keywords published mainly for the last 10 years was done; also, a reference list of each selected article was analysed. We included to our review the articles reporting controversial issues or new data on the treatment of hyperprolactinemia.Results: The review describes various problems arising during the treatment of prolactinoma. The presence of primary and secondary dopamine agonist resistance in each case requires an individual approach, and sometimes may include the use of the antineoplastic agent temozolomide. The side effects of dopamine agonists are discussed, with quite rare ones, including valvulopathy, pathological psychological conditions and cerebrospinal rhinorrhea. The controversial issue of the duration and doses of the drug used to achieve a lasting effect in the treatment of prolactinomas is considered. There are some points connected with the frequency of relapses. Thus, recurrence is correlated to the duration of treatment with dopamine agonists, prolactin levels at diagnosis, and the initial tumor size. Metformin, somatostatin analogues, selective estrogen receptor modulators, tyrosine kinase inhibitors, inhibitors of the mammalian target of rapamycin, epidermal growth factor receptor antagonists are investigated nowadays as potential alternative methods of drug treatment of prolactinomas.

Conclusion: Drug therapy with dopamine agonists makes it possible to achieve the desired results in the vast majority of patients. However, despite the proven safety of this group of medicines, the risk of side effects should still be taken into account. The therapy regimen should be determined by the clinical course of prolactinoma and the patient’s response to treatment. Other options of treatment should be considered in patients intolerant to medical therapy, with contraindication or resistance to dopamine agonists, in the case of a malignant tumor. The presence of refractory to any of the applied methods of treatment and aggressive prolactinomas leads to the search for new drugs.
Optimization directions of exploration and development of oil fields of the Western Fore-Black Sea area of Ukraine
Authors: Lazaruk Yaroslav , Pavlyuk Myroslav
Published: December 2023

The southern part of the Dobrogea Foredeep is located in the southwestern regions of Ukraine within the Odesa region. Here, on the territory of the uplifted Bilolissya block, the East Sarata, Zhovtyjar, Saryjar, Zarichna oil accumulations are located in the chemogenic-carbonate layer of the Middle and Upper Devonian. The deposits are confined to limestones and dolomites with secondary fractured-cavernous-porous reservoirs. They lie at depths of 2500–3200 m. During the test of two dozen wells, the filtrate of the drilling fluid with a small amount of oil was received with the estimated flow rates of several tons per day. The rise of the oil level in the wells was quickly stopped, the hydrodynamic connection of the wells with the productive formations was lost. The use of today's known methods of intensification of the flow of hydrocarbon fluids did not lead to positive results. According to the research of microphotographs of reservoir rocks, it is proved that the largest voids of reservoir rocks are filled with immobile bitumen, while the smaller cavities contain mobile oil. Immobile bitumen fills main channels and blocks communication between rock cavities. This is the main reason for the absence of industrial inflows of oil to the wells. Another important reason is the low filtering properties of the collectors. Most of them have a permeability of less than 0.01∙μD. Other reasons for the failure of the industrial development of oil deposits are the high dynamic viscosity of oil due to the high content of asphaltenes, silicagel resins, paraffins, the low energy potential of oil deposits due to their degassing during the long geological time, as well as the lack of hydrodynamic connection of oil deposits with natural water pressure systems. We assume that the Middle and Upper Devonian oil fields of the Western Fore-Black Sea area are most likely mainly bituminous. Given the significant depths of the deposits, their industrial development is technically impossible today. Therefore, it is impractical to plan further scientific research on the mentioned complex. Instead, research should be reoriented to the Silurian terrigenous-carbonate complex and the Lower Devonian terrigenous complex, which are hydrodynamically more closed and in which non-degassed hydrocarbon accumulations can be preserved.
DIETARY PROTEIN REQUIREMENT OF DAPHNIA MAGNA FOR THE IMPROVEMENT POPULATION AND NUTRITIONAL VALUE OF DAPHNIA
Authors: Kasmawijaya Adang , Hasan Otie Dylan Soebhakti , Zaidy Azam Bachur
Published: December 2023

Daphnia magna is one of the live feeds used in aquaculture, but its availability is still limited. The population and nutritional quality of D. magna culture depend on the nutritional quality of feed where the feed source is commonly used from agricultural by-products. In contrast, pelleted feed as a source of nutrition in D. magna culture is still limited. Evaluation of commercial pelleted feeds with different protein levels and dietary protein requirements of D. magna is the focus of this research. Three treatments with different protein levels of feed with protein levels of 17.83% (P20), 32.35% (P30) and 41.98% (P40) and rice bran as control at a protein level of 8.2% (P10) with five replications for 28 days of rearing with using a completely randomized design. The average weekly population and the highest total biomass of D. magna were obtained from D. magna fed the P30 (Protein 32.35%) of 7,575 ind. tank-1. week-1 and total biomass of 290.26 g.m-3 with the feed conversion ratio of 3.85 ± 0.75 and protein efficiency ratio of 0.83 ± 0.14. The highest protein value of D. magna was obtained from D. magna fed the P30 of 3.02% ± 0.20 wet weight. The results showed that feed with a protein content of 32.35% (P30) showed the best results for cultivating D. magna. The estimated dietary protein requirement of feed for D. magna cultivation using the second polynomial regression analysis of feed protein - population and biomass is 38.8%.

Published: December 2023

Process capability in processing fishery products is a future challenge for the fishing industry, one of which is katsuobushi. The capability process refers to how a company can produce according to specifications to make it effective and efficient. The absence of process capability in the company is the basis for stating an effective and efficient process. The proposed study is to determine the company's current condition and provide suggestions for process improvement and evaluation. Through assumptions, this study influences the results of Cp and Cpk, which are calculated by Minitab software version 21st  as a method for measuring performance by identifying broad process tolerance production. In this study, the results for each data generated met data accuracy and standards. Still, at smoking 3rd and 4th stages, it was necessary to review specification values because of the value of Cpk < 1.00. As a result, after improving the standard by the six sigma concept, Cpk values are obtained > 1.00.

Suffering into patrimony: dealing with communist repression in postcommunist Romania
Authors:   “Nicolae Iorga” Institute of History, Bucharest, Romania, Dobre Claudia-Florentina
Published: December 2023

Analyses of communist repression in post-communist Romania focused on anticommunism and its totemic figures. Laws, institutions and people promote this perspective, transforming the suffering of the formerly politically persecuted into a patrimony meant to be preserved and passed on. On the official level, the anticommunist paradigm gained momentum in December 2006 when the communist regime was condemned as ‘criminal and illegitimate’. However, a majority of the population have not embraced the official approach to communism as the fallen regime still acts as a ‘millieu de memoire’ (as defined by Pierre Nora). My article deals with the main institutions and laws which aimed at promoting and transmitting the memory of repression in post-communist Romania. Analyzing the memory politics as regards the communist repression might provide fresh insight into the ongoing process of building a cultural memory through selection, reconstruction and adjusting figures, deeds, and memorial items.
Juvenile feeding of pacific salmon in the lower part of the Pymta River in May–September, 2019–2020
Authors: Travina T. N. , Gerlits A. I.
Published: December 2023

Comparative analysis of feeding in the lower part of the Pymta River (West Kamchatka) is carried out for juvenile Pacific salmon individuals of different age representing four species with a short or long freshwater period of their life cycle (chum salmon Oncorhynchus keta, sockeye salmon O. nerka, coho salmon O. kisutsch and Chinook salmon O. tschawytscha) for the period from May to September in 2019–2020. Spectra of food, stomach fullness indices and degree of food similarity between juveniles of different species and age classes are demonstrated. The feeding in all mentioned species was biotop-dependent. There were frequent changes in the composition of the forage consumed in the course of observations of Pacific salmon juveniles in the Pymta River basin, and the indices of stomach fullness varied extensively. The results of the analysis indicate extensive trophic adaptability in juvenile Pacific salmon in the ecosystem of the Pymta River.

Predictive Analysis of Water-Level Changes in Lake Baikal: Social, Economic, and Environmental Impacts
Authors: Sorokina Polina
Published: December 2023

For many years, scientists, the public, as well as the population of coastal settlements have been concerned about the water level in Baikal, as its fluctuations lead to various socio-economic and environmental problems. In this regard, to predict the water level in Baikal, the task of building mathematical models of the dependence of the level on the factors that influence its importance is very relevant. The aim of this work is to construct such a mathematical model using econometric research methods. Six econometric models were built in the analysis. After testing them for adequacy, the author chose a polynomial model based on which point and interval forecasts were built. The average error of the approximation obtained (the average deviation of the predicted water level from the actual) is 0,03 % which indicates a high accuracy of the selected model. The work also discusses possible (some of the already existing) socio-economic and environmental problems of two fishing areas — the Barguzinsky Bay and the Gulf of Debacle. This study is an exploratory research and has practical value. In the future, the author plans to improve the quality of the model by increasing possible factors that influence changes in the level of Lake Baikal.

Published: December 2023

The study considered the theory of correlation between sets of composite index objects. Index objects are letters of the alphabet, compound objects are words. The theory is used to find a correlation between the toponyms of the Irkutsk region and the words of the ancient language — Sanskrit. Toponyms grouped according to the names of settlements (in the amount of 1 145), rivers (141) and mountains (451) have been studied. Toponyms are compared with the vocabulary of the Sanskrit dictionary, consisting of 1 100 words. The study found a correlation between Buryat and Evenk toponyms and words from Sanskrit at the level of 62–65 %. We discussed the historical reasons for the appearance of words from Sanskrit in Eastern Siberia. We have given a large number of examples of the connection between Buryat and Evenki toponyms with words from Sanskrit and the Old Russian language.

Published: December 2023

The Synchrotron-light for Experimental Science and Application in the Middle East (SESAME) facility is in the process of designing, procuring, and installing a new beamline for tomography (BEATS). The BEATS experimental hutch, hosting sample and detectors, will be located 43 m away from the undulator in the synchrotron ring. Noise in the form of vibration originating from different sources transferred to the detector stage can be a source of poor image quality thus it is important that the detector stage is analysed for its vibration transmission properties. In this study, the result of a three-dimensional random vibration analysis using Finite Element Analysis (FEA) for the detector stage is presented which leads to an estimate of the severity of the vibrations. The random vibration source is that of the ground which was measured exactly where the detector stage will be mounted. The random vibration analysis is conducted in two stages; the modal frequencies of the structure are calculated, thereafter, the random vibration analysis is conducted and the response power spectrum density (PSD) of the structure is calculated along with the root mean square (RMS) displacement values. Since the beamline BEATS is under installation, an existing structure installed at beamline ID28 of the European Synchrotron Radiation Facility (ESRF) was used to validate the model. The model used on the ID28 structure deviated from the experimental results on modal analysis by 2% - 4% on random vibration analysis. This suggested that the model is valid. The analysis as applied to the BEATS detector stage design predicts that the RMS displacement values are less than the pixel size of the detector which is 1 μm. Thus, the structure is sufficiently engineered to moderate the floor vibrations.
Timing Pulsars with CHIME and the NANOGrav 15yr Dataset
Authors: Agazie Gabriella Yehenew
Published: December 2023

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) conducts long-term timing campaigns on large numbers of millisecond pulsars (MSPs). Wideband (WB) timing of the NANOGrav datasets was first done in the 12.5yr dataset, and proved to be extremely helpful for measuring the time-varying dispersion measure, which can significantly limit timing precision. However, we are limited by the fact that NANOGrav only observes most pulsars once per month. In contrast, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Telescope currently observes most NANOGrav MSPs at nearly daily cadence at 600 MHz with a 400 MHz bandwidth. Using WB timing techniques, we combined one year of data taken at CHIME with data over the same time period from the NANOGrav 15yr Dataset for three MSPs.

Harbetsuvan Tepesi, Şanlıurfa'nın 53 km doğusunda bulunan Tek Tek Dağları bölgesi içerisinde yer almaktadır. İlk kez 2014 yılında bölgede yapılan yüzey araştırmaları sırasında tespit edilmiş olan Harbetsuvan Tepesi’nde Şanlıurfa Müzesi Müdürlüğü başkanlığında 2017-2019 yılları arasında arkeolojik kurtarma kazıları yapılmıştır. Yapılan kazılarda pek çok mimari ve küçük buluntu ele geçmiş, bu sayede Harbetsuvan Tepesi’nin Göbekli Tepe, Karahan Tepe, Sayburç, Nevali Çori, Ayanlar Höyük, Şanlıurfa-Yeni Mahalle, Sefer Tepe, Kurt Tepesi, Hamzan Tepe ve Taşlı Tepe ile benzer özellikler taşıdığı ve Çanak Çömleksiz Neolitik Döneme ait bir yerleşim olduğu anlaşılmıştır. Harbetsuvan Tepesi’nde ele geçen küçük buluntulara bakıldığında bunların en yoğun olarak görüleni çakmaktaşından yapılmış buluntular olarak karşımıza çıkmaktadır. Çakmaktaşından yapılan aletler, ok ve mızrak uçları, kazıyıcılar, deliciler, orak dilgiler ve taş kalemler şeklindedir. Ele geçen çakmaktaşı çekirdekler, çoğunlukla iki kutuplu naviform çekirdekler şeklindedir. Obsidyenlere bakıldığında ise bunların daha çok dilgilerden oluştuğu görülmektedir. Obsidyen çekirdek yenileme parçalarının ele geçmiş olması alet yapımının yerleşimde gerçekleştirildiğini göstermektedir. Ayrıca obsidyenden yapılmış bir adet Byblos tipi ok ucu da bütün bir şekilde ele geçmiştir. Diğer küçük buluntulara bakıldığında ise serpantin ve kireçtaşından yapılmış bezemeli taş plakalar ve boncuklar karşımıza çıkmaktadır. Taş plakalar üzerindeki bezemeler de genel olarak geometrik motifler şeklindedir. Bu çalışmada, Harbetsuvan Tepesi’nde ele geçen küçük buluntuların tümü birlikte değerlendirilmiştir.

Lifeplan is a global biodiversity monitoring project with the aim of assessing the current state of biodiversity worldwide, and using this knowledge to generate predictions of how biodiversity might look in the future. In this protocol we describe the materials and method used to sample flying insects with a Malaise trap for the Global Malaise Trap Project and the LIFEPLAN project on a global scale and in a wide variety of environmental conditions and habitats. The aim is to identify species in further analysis (e.g. image recognition, DNA sequencing) and create species lists for different locations across the globe. This protocol contains a detailed description from setup of the Malaise traps in the field to weekly data collection, as well as steps to reduce ethanol in the samples and collect necessary information to help in species identification. We identify the equipment used in Lifeplan, but also give technical specifications of that equipment so that other users of this protocol can find equivalent alternative equipment. We also specify what metadata should be collected with the Malaise trap data. The technical solution we use to collect metadata in the Lifeplan project is described in detail in the full Lifeplan protocol. It is critical that we employ standardized operating procedures for the Malaise trapping. Our coordinated efforts will ensure specimen preservation for sequence analysis and high data quality, permitting the comparison of sites at a global scale. For global standardization with the BIOSCANinitiative, of which LIFEPLAN is a part. LIFEPLAN is based on bulk processing (metabarcoding) of samples and automatic image recognition which are outside of the scope of this protocol and will be described elsewhere.

TikTok/Flipgrid for Foreign Language Learning in Higher Education: A Case Study
Authors: Pérez-Sabater Carmen , Cerezo-Herrero Enrique , Barbasán Ortuño Inmaculada
Published: December 2023

The interweaving of in-person and online teaching at the university level requires the implementation of new resources that allow the coexistence of these two forms of education. To that end, we addressed the incorporation of TikTok and FlipGrid at the university for speaking practice in the foreign language classroom. We compared the results of this teaching experience in three courses, in two foreign languages, English B2 and Italian A2, in engineering degrees. The methodological design of this research comprised a classroom intervention, an analysis through surveys, and feedback sessions. The results indicate that the use of short videos for speaking practice is motivating and enriching in all the study groups and in both languages, although the participants do not consider the use of TikTok appropriate at university. In FlipGrid, on the other hand, there have been no doubts about its suitability for academic purposes. Besides, the comparison between languages, and therefore levels, indicates that Italian A2 learners view TikTok with a more positive attitude than those of English B2. Our findings bring to the fore the potential of short video recording and the need to link the academic and social contexts for a more well-rounded educational experience.
Deconstructing women’s double burden that returned to work during the COVID-19 pandemic
Authors: Feitshans Ilise
Published: December 2023

The double burden for women has returned during the COVID-19 pandemic. As a result of the pandemic, an unprecedented percentage of women have lost their jobs or are working from home. The COVID-19 pandemic has brought back a centuries old burden, which adds to the many other burdens women face regularly – the homework burden –, that is engaging in piecework and childcare at the same time. Mapping the laws and the legal determinants of women’s health disparities must be undertaken to stem the tide of this new wave of the feminization of poverty.
