Short and medium run effects of fiscal policy in an economic and monetary union : the case of a small country
Authors: Konopczyński Michał
Published: September 2023

We analyze the effectiveness of fiscal policy in an economic and monetary union. On the basis of a simple static and dynamic Mundell-Fleming model, we show that expansionary fiscal policy is very effective in the short run, but in the medium run all positive effects are "exported" abroad due to impaired competitiveness. These results are illustrated by numerical simulations. High short-run effectiveness of fiscal policy may have contributed to excessive deficits in many EMU countries. (original abstract)
The emergence of entrepreneurship in organizations : joint decision-making about new sales practices in management group meeting interaction
Authors: Peltola Soili , Mikko Kari
Published: September 2023

This study examines the emergence of entrepreneurship in organizations. The material consists of the audio-recorded meetings of management group members in one Finnish firm specialized in management services. The analysis illustrates how the members jointly negotiated new entrepreneurial sales practices in their meeting interaction but failed to demonstrate commitment to their future application. The findings conceptualize the emergence of entrepreneurship as a collaborative, four-stage decision-making process based on shared understandings of entrepreneurial ideals. They further suggest that this process is contingent on the agreement and commitment of organizational members to whom the responsibility to apply entrepreneurial practices in their daily work is assigned.

На основі дослідження сучасного стану вітчизняних промислових підприємств встановлено, що незважаючи на потужний промисловий потенціал України  відсутність стратегічного бачення розвитку промисловості та реалізації стратегічно значущих для даного сектору реформ призвело до поступової деградації промисловості і втрати потужного сектору  економіки. З’ясовано, що різке  скорочення обсягів виробництва та експорту продукції промисловості, зокрема машинобудівного сектору, є результатом реалізації протягом багатьох років політики деіндустріалізації економіки, декларативного характеру реалізації  стратегічних та програмних ініціатив розвитку даного сектору, високу фізичну та моральну зношеність інфраструктури і обладнання, використання застарілих технологій, низького рівня накопичення  основного капіталу, відтоку інтелектуальних ресурсів і низької конкурентоспроможності вітчизняної промислової продукції на світовому ринку. Доведено, що зважаючи на експоненціальний характер зміни інноваційних трендів розвитку промисловості,  прискорення роботизації та цифровізації діяльності промислових підприємств виникає потреба в перегляді дієвих інструментів управління їх  діяльністю і забезпечення сталого зростання з акцентом не лише на своєчасній адаптації до внутрішніх та зовнішніх змін, але й на прогнозуванні такого роду трансформацій і передбаченні можливих викликів та загроз. Розкрито особливості проактивно-інноваційного управління промисловими підприємствами, впровадження інструментів якого сприятиме стабілізації їх діяльності та забезпеченню інноваційної модернізації підприємств вітчизняного промислового сектору.

У статті проаналізовано теоретичні та практичні основи організації обліку запасів, які необхідно вдосконалювати в напрямку розширення її управлінських  можливостей, максимально пристосовуючи до практичних потреб суб'єктів підприємницької діяльності, що виникають в процесі прийняття управлінських рішень щодо руху запасів та ефективності їх використання. Для здійснення виробничо-господарської діяльності підприємствами всіх форм власності та галузей економіки  використовуються товарно-виробничі запаси, які є найбільш важливою та значною частиною активів підприємства. Вони  займають особливе місце у складі майна та домінуючі позиції у структурі витрат підприємств різних сфер діяльності. Запаси є складовою частиною групи матеріальних ресурсів, які формують економічні  (виробничі) ресурси. Запаси – це активи, які використовуються для подальшого продажу, споживання під час виробництва продукції, виконання робіт і надання послуг, а також управління підприємством. Питання сутності запасів з різним  ступенем теоретичного і  практичного висвітлення розглянуто в багатьох сучасних виданнях. Обґрунтовано необхідність дослідження економічної сутності запасів на підставі систематизації економічних джерел та нормативно-правових актів. Теоретично обґрунтовано значимість запасів для функціонування суб'єкта господарювання. Здійснено огляд законодавчих актів і нормативних документів, які регламентують облік операцій із запасами. Основними шляхами вдосконалення організації обліку запасів є раціоналізація як кожної форми документів і регістрів  обліку, так і методів і способів збору, обробки та узагальнення облікової інформації, адаптованих до сучасних умов. Розглянуто фактори, що впливають на облік запасів. Наведено етапи удосконалення документального оформлення надходження, наявності та витрачання для контролю й оперативного управління запасами шляхом зміни структури документообігу та змісту рахунків обліку . Від правильно  організованого первинного обліку господарських засобів залежить правильність списання вартості сировини і матеріалів на  виробництво, оцінка незавершеного виробництва, відображення у  звітності. Визначено сутність окремих документів як фактору впливу на процес управління. У ході дослідження застосовувалися методи системного аналізу, логічного узагальнення, абстрактно-логічні методи. Обґрунтовано перспективи подальших досліджень організації і методики операцій із запасами на підприємствах.

Barki desantowe Andrew Jacksona Higginsa narzędziem sukcesu operacji „Overlord”
Authors: Zuziak Janusz
Published: September 2023

W latach II wojny światowej alianci stanęli przed poważnym problem związanym z wieloma morskimi operacjami desantowymi, prowadzonymi zarówno na Pacyfiku, jak i w Europie. Dla ich sprawnej realizacji koniecznym było skonstruowanie i zbudowanie różnorodnych łodzi i barek desantowych. Wśród nich znalazły się legendarne barki desantowe LCVP (Landing Craft Vehicle Personnel), zaprojektowane przez Andrew Jacksona Higginsa, amerykańskiego konstruktora i budowniczego łodzi pełnomorskich. Dzięki nim możliwe było m.in. lądowanie tysięcy żołnierzy i sprzętu na otwartych plażach Normandii w trakcie operacji „Overlord” w czerwcu 1944 r. Ostatni etap transportu żołnierzy i sprzętu z okrętów i statków na plaże Normandii był – zdaniem wielu wojskowych – najtrudniejszy. Potrzebowano do tego lekkich łodzi i barek desantowych, które byłyby w stanie przewieźć ludzi i sprzęt po płytkiej wodzie z okrętów na ląd. I wówczas właśnie Andrew J. Higgins zaproponował kilka rodzajów łodzi desantowych, w tym słynną LCVP. Nie ulega wątpliwości, że barki Higginsa w istotny sposób przyczyniły się do sukcesu alianckiej operacji lądowania na plażach Normandii.

Authors: Ferrari Angélica , Corrêa dos Santos Alexandre , Klann Roberto Carlos
Published: September 2023

Ainda é controverso na literatura contábil a capacidade dos ativos intangíveis em gerar desempenho econômico e de mercado persistente nas organizações. Em economias mais fortes esse papel estratégico parece ser mais claro, porém, em economias em desenvolvimento, isso não é muito debatido e pouco se conhece do ponta de vista empírico. Diante disso, este estudo objetiva analisar a influência do índice de intangibilidade sobre o desempenho econômico e de mercado. A população de pesquisa é formada por empresas brasileiras listadas na Brasil, Bolsa e Balcão (B3), cujos dados foram coletados no banco de dados Refinitiv Eikon para o período de 2010 a 2019, perfazendo uma amostra final de 148 empresas brasileiras, totalizando 1.148 observações. Para a análise dos dados foram realizadas regressões lineares múltiplas com especificação por erros robustos, cujos resultados apontam que os ativos intangíveis de empresas brasileiras listadas influenciam positivamente o desempenho de mercado, mas o mesmo não ocorre para o desempenho econômico, que apresentou relação estatística negativa.

Authors:   East European and Balkan Institute, Kim Yongdeog
Published: September 2023

On May 1, 2014, 10 years have passed since Poland joined the European Union. In 2004 Poland joined the European Union as one of the poorest countries in Europe. Among them, serious problems in the labor market, such as extreme unemployment, were also included. The purpose of this paper is to compare and analyze the situation at the time of the first 10 years of joining and present the results, after examining the state of Poland’s economy and its weaknesses at the time of joining to the European Union. It will also be able to look at the losses incurred by joining to the European Union along with the gains it has brought. These include matters such as - the financial impact of becoming a membership, the consequences of the European Union’s participation in the Common Regional Policy and the New Cohesion Policy, the economic development of trade within the scope of the Single European Market, and the trends of Polish migration abroad to the Western European labor market.
The Closure of the Semipalatinsk Nuclear Test Site and the Anti-nuclear Activities of the  Group
Authors:   East European and Balkan Institute, Yang SeungJo
Published: September 2023

In the midst of the Cold War, the Soviet Union conducted numerous nuclear tests as part of the nuclear weapons development race. The Semipalatinsk Test Site, the most prominent nuclear testing ground operated by the Soviet Union, witnessed a total of 456 nuclear tests in the air, on the ground, and underground over a span of 40 years since 1949. As the cradle of Soviet nuclear weapons development, this site sparked a grassroots anti-nuclear movement within Kazakhstan towards the end of the Soviet era. The activities of the ‘Nevada-Semipalatinsk’, an anti-nuclear citizen group in Kazakhstan led by Olzhas Suleimenov, garnered support not only within Kazakhstan but also from the Soviet leadership and national and civil organizations worldwide, resulting in the closure of the Semipalatinsk Test Site. However, the closure of the Semipalatinsk Test Site marked not the end but rather the beginning of addressing the more fundamental issue of damages caused by radioactive materials. The Soviet Union disregarded the harms inflicted upon the residents living near the testing site and its surrounding areas during the nuclear tests. However, as a result of the nuclear tests conducted in all areas of the site, the Semipalatinsk Test Site and its adjacent region suffered severe contamination of both surface and underground water sources, leading to various health problems and the occurrence of deformities among the affected residents. After the dissolution of the Soviet Union, international cooperation and independent efforts by the government of Kazakhstan were undertaken to remove the remnants of nuclear testing and radioactive contamination in the former Semipalatinsk Test Site and its surrounding areas. Based on the results of these efforts, the current government of Kazakhstan claims that the contamination caused by radioactive materials has largely disappeared and emphasizes the need for various forms of economic activities and development in the region. However, civil organizations in Kazakhstan and abroad argue that the area is still contaminated by radioactive materials, exposing a significant number of residents to associated damages.

Poverty is a condition that concerns the inability to meet the most minimum demands of life, especially from the aspects of consumption, income, education, and health. The problem of poverty is very complex and multidimensional in nature, as it relates to social, economic, cultural and other aspects. This study focuses on observation areas in South Kalimantan Province, with the PPM value in 2021 reaching (4.83%) still above the target goal of the Regional Medium-Term Development Plan (RPJMD) of South Kalimantan Province (3.96- 4.01%), so that further interventions are still needed to be able to reduce PPM in poverty cases. This study aims to estimate the parameters of the panel regression model used to analyze factors that are suspected to affect poverty cases in South Kalimantan Province in 2016-2020. The Random Effect Model (REM) is the best model used in this study, assuming that there are differences in slopes and interceptions caused by residual due to differences between individual units and between time periods. The process of estimating parameters on REM is determined through the Generalized Least Squares (GLS) Estimator method . From the results of the data processing, it was obtained that the model is influenced by economic growth, life expectancy, open unemployment rate, and labor force participation rate. From the results of the analysis of 2 (two) models, it was tested significantly and affected poverty in South Kalimantan Province in 2016-2020.  Keywords:   Poverty, Data Regression Panel, Generalized Least Square Method (GLS).

Published: September 2023

Kebanyakan penduduk cenderung meningkat dan ketersediaan lahan semakin berkurang setiap tahun akibat migrasi. Upaya peningkatan kualitas penduduk akan lebih sulit dilakukan di daerah dengan kepadatan tinggi, sehingga dapat menimbulkan masalah baik di bidang sosial ekonomi, ketersediaan lahan, maupun kebutuhan pangan. Oleh karena itu, perlu diketahui faktor-faktor yang mempengaruhi kepadatan penduduk. Salah satu pendekatan untuk memprediksi pola hubungan antara faktor dan kepadatan penduduk, dapat menggunakan regresi Poisson. Regresi Poisson merupakan salah satu regresi nonlinier yang sering digunakan untuk memodelkan variabel dalam bentuk bilangan bulat. Penelitian ini bertujuan untuk mendeskripsikan karakteristik penduduk setiap provinsi di Indonesia,mengestimasi parameter model regresi Poisson dan menjelaskan faktor-faktor yang berpengaruh signifikan terhadap masalah kepadatan penduduk. Faktor-faktor yang diduga berpengaruh terhadap kepadatan penduduk adalah jumlah penduduk, luas wilayah, jumlah SD, jumlah SMP, jumlah SMA, jumlah puskesmas, jumlah koperasi dan jumlah kematian. . Hasil penelitian ini menunjukkan bahwa model regresi Poisson digeneralisasikan , bahwa faktor-faktor yang mempengaruhi kepadatan penduduk setiap provinsi di Indonesia pada tingkat kepadatan penduduk (Y) dan jumlah penduduk  mempunyai hubungan yang searah, artinya setiap pertambahan satu penduduk maka pertambahan penduduk bertambah sebesar 9,7 %, sedangkan luas wilayah mempunyai hubungan kebalikan sebesar 0,0136%, artinya semakin sempit satu satuan luas, maka tingkat kepadatan penduduk bertambah sebesar 0,0136%.

Authors: Pinto Cerqueira Walter Ramos , Garcia Tavares Yara Aparecida , Semanovschi Natalie Petrovna , de Jesus Daniele Nascimento
Published: September 2023

This study analyzes the morphometric aspects of two populations of Echinometra lucunter (Linnaeus, 1758) on Pituba and Itapuã beaches (Salvador, Bahia). Linear and volumetric measurements were performed on 117 specimens (test diameter > 40 mm) and the ratios between them were analyzed along with Aristotle’s lantern weight participation (AL index). The potential model was tested between AL wet weight and tooth height (log data), estimating the coefficients by linear regression. Echinoid specimens from Pituba (n = 57) manifested a higher average degree of sphericity and test thickness. Proportionally, this population also showed higher AL and tooth height, indicating that the dimensions of this structure exhibit particularities in the spatial arrangement along the oral-aboral axis of the echinoids. Negative allometric relationships (β < 1) were observed in all specimens. The environments with distinct characteristics and wide food availability associated with a broad spectrum of the trophic niche occupied by the populations point out modulations and specializations of morphofunctional strategies and the expression of phenotypes.

Authors: Di Cesare Antonio , Belviso Prospero , Ponzo Felice Carlo , Vitone Giovanni
Published: September 2023

This paper presents the experimental and numerical study on a ductile beam-column connection between a composite reinforced concrete truss (CRCT) beam and Concrete Filled Tube (CFT) column subjected to bending and shear loads. Two experimental models with different beam-column joint testing schemes, extracted from the same prototype three-dimensional structure designed according to the rules of the capacity design provided by seismic code, were subjected to quasi-static cyclic tests by applying gravitational loads and the horizontal seismic force. The main objective of this paper is to verify the experimental ductile behavior of both specimens and to simulate the experimental global and local response by nonlinear static analysis considering different modelling approaches. The comparison between the experimental and numerical results highlights, for both models considered, the ductile and dissipative capacity of the connection system, designed following the criterion of the hierarchy of resistances proposed by the current Italian code. Different experimental setup showed similar results demonstrating the repeatability of the test and its reproducibility through the nonlinear numerical analysis.

Study on the Influence of Thermodynamic Effects on the Characteristics of Liquid Nitrogen Cavitating Flow around Hydrofoils
Authors: Fu Yuzhuang , Gao Bo , Ni Dan , Zhang Wenbin , Fu Yanxia , Lu Sheng
Published: September 2023

The cavitation behavior of cryogenic liquids in the field of cryogenic engineering is distinct, showcasing fundamental differences from the cavitation behavior observed in ambient temperature water. Cavitation occurrence imposes severe limitations on the operational stability of cryogenic media transportation equipment, leading to safety concerns and increased manufacturing costs. Investigating the spatiotemporal characteristics of cavitation in cryogenic fluids holds significant value for both academia and engineering. The complexity of cavitation in cryogenic fluids primarily manifests through the coupled effects of thermodynamics, vortices, and bubbles during the cavitation process. In order to further explore the coupling mechanism, numerical simulations employing the Delayed Detached Eddy Simulation (DDES) turbulence model and Sauer-Schnerr cavitation model are conducted to validate the accuracy of the numerical calculations using the Hord experiment hydrofoil as a benchmark. Subsequently, the unsteady cavitation flow of liquid nitrogen around the NACA 0015 hydrofoil is simulated by the same numerical calculation method. The results indicate that the simulated results best coincide with experimental results when the bubble number density in the Sauer-Schnerr cavitation model reaches 108. The upstream development of the re-entrant jet under the driving force of inverse pressure gradient is the fundamental reason for the detachment of the primary cavitation zone. Under the same inflow cavitation number, the thermodynamic effect significantly inhibits the generation of bubbles and changes the range of the inverse pressure gradient, thus affecting the separation behavior of the primary cavitation zone.

Published: September 2023

There are few studies of the psychological effects of language brokering (speaking on behalf of) among minors migrated to Europe, even though language brokering is becoming more current in many migrant families. As the psychological implications of language brokering remain controversial, further investigation is needed. Earlier studies have documented that language brokering is sometimes linked with emotional maladjustment and developmental drawbacks, but other studies have shown faster acquisition of social and Language skills. The present study assessed the relation of language brokering with psychological well-being in a sample of Latino migrant adolescents living in Italy; the dependent variables were depression, anxiety, and emotions. Statistically significant differences between boys and girls confirmed the sex-specificity of language brokering and the lack of statistically significant negative association between language brokering and psychological well-being.

Published: September 2023

Landslide is one of the most common geological disasters in China, which is characterized by suddenness and uncertainty, and it is difficult to realize accurate identification, early warning and forecasting of landslide disaster by conventional means. With the development of high-resolution remote sensing satellites and InSAR surface deformation monitoring technology, the traditional means of landslide monitoring data sources are limited, and there is a lack of effective methods to excavate the characteristics of the spatial distribution of landslide hazards and their triggering factors and other issues. In this paper, the area extending 10 km outside the VII isobar of the Gengma earthquake is taken as the study area, and 13 evaluation factors are screened out by integrating the factors of InSAR surface deformation, topography and geological environment, and the Bayesian Optimized Convolutional Neural Network (BO-CNN) is used for the evaluation of landslide susceptibility, and the BO-RF and PSO-SVM models are selected for the comparative analysis. The model accuracy evaluation was carried out by three indexes: ROC curve, AUC value and FR value, in which the ROC curves of PSO-SVM, BO-RF and BO-CNN were all close to the upper-left corner of the corner, and the AUC values were 0.9388, 0.9529, and 0.9535, respectively, and the FR value of landslide in the high susceptibility area of BO-CNN was as high as 14.9, and was higher than that of PSO-SVM and BO-RF, respectively. SVM and BO-RF model is 4.55 and 3.69 higher, the experimental results show that the BO-CNN model used in this paper has a better effect in landslide susceptibility evaluation, and the research results of the local government's disaster prevention and mitigation measures are of great significance.

Authors: Cieśla Maria
Published: September 2023

Recent global trends related to the increasing use of e-commerce are becoming a challenge for courier transport especially in the last-mile process of delivering products to the final retail recipient. One of the delivery methods is the personal collection of the parcel in an automated post box, available 24/7 for the customer. This research aims to define the most important attributes of the courier services quality, including the delivery of parcels through automated sending and receiving parcel lockers, leveraging advanced technologies, data, and connectivity to enhance the quality of life, sustainability, and efficiency for city residents. The research was based on a preliminary selection of the most important features of parcel lockers’ service quality, which were extracted from the analysis of scientific literature and previous research. The analysis was carried out by conducting a survey among city parcel locker users that provided data coded according to the dimensions of the Kano model. This allowed to conclude that the location of parcel stations, ensuring improvements for the disabled, adjusting the size of the parcel to the size of the box, proper placement of the parcel in the box and a properly functioning dedicated application are the most important features in the process of automatic delivery of parcels to recipients in urban areas. This paper enriches the literature on customer service quality of self-service technologies for last-mile delivery with the use of automated parcel lockers.

Published: September 2023

Background: Radiotherapy is an important part of the medical therapy concept treating tumors in the head and neck region; however, the impact on the field of dentistry could be im-mense. The objective of this study was to evaluate the microtensile bond strength (µTBS) of uni-versal adhesives and to compare the results of different application modes (etch-and-rinse and self-etch) on irradiated and sound human dentin. Methods: Dentin specimen of 180 extracted human wisdom teeth were divided in two superordinate groups. Ninety teeth received either no irradiation (control group) or the high-level therapeutic dose of 60 Gy (test group) applied frac-tionally (2 Gy/day, 5 days/week, 6 weeks). Samples from each group were randomly divided in-to six subgroups assigned to three established universal adhesives (Futurabond® U, VOCO; AdheSE® Universal, Ivoclar Vivadent; Xeno® Select, Dentsply) in both conceivable application modes: etch-and-rinse and self-etch (n = 15). Bond strength was assessed with a universal testing machine immediately after application and light curing of the adhesive materials. Statistical analysis was performed using two-way ANOVA (p<0.01) and Tukey's test (p<0.05). Results: The effect of dentin irradiation and application mode for the adhesive restoration was found to be significant (p<0.01, ANOVA). In all groups, a decrease of µTBS could be observed when used on irradiated dentin. However, no significant influence of high level radiation on the bond strength of Futurabond® U and AdheSE® Universal in both modes could be evaluated (p>0.05, Tukey´s test). Solely in the case of the adhesive system Xeno® Select, significantly reduced bond strength could be determined in self-etch mode after irradiation (group 60 Xse) compared to the control group (0 Xse) (p<0.05, Tukey´s test). Conclusions: Within the limitations of an in vitro study, some effects of high-level tumor irradiation on the bond strength of universal adhesives can be detected. However, these effects were strongly depending on the used material and application mode.
The magic Triangle in Oral Potentially Malignant Disorders: Vitamin D, Vitamin D Receptor, and Malignancy
Authors: Khamis Aya , Salzer Lara , Schiegnitz Eik , Stauber Roland H. , Gül Désirée
Published: September 2023

OPMDs (Oral Potentially Malignant Disorders) are a group of disorders affecting the oral mucosa that are characterized by aberrant cell proliferation and a higher risk of malignant transformation. Vitamin D (VitD) and its receptor (VDR) have been extensively studied for their potential contributions to the prevention and therapeutic management of a range of diseases and neoplastic conditions, including oral cancer. Observational studies suggest correlations between VitD deficiency and higher cancer risk, worse prognosis, and increased mortality rates. Interestingly, emerging data also reveals a link between VitD insufficiency and the onset or progression of OPMDs. Understanding the role of the VitD-VDR axis not only in established oral tumors but also in OPMDs might thus enable early detection and prevention of malignant transformation. With this article, we want to provide an overview of current knowledge about OPMDs and VitD, and investigate their potential association and ramifications for clinical management of OPMDs.

Published: September 2023

Eustachian Tube Dysfunction is considered a common condition among ENT patients and requires careful history, clinical examination and appropriate investigations to obtain a diagnosis. The ETDQ-7 questionnaire is a useful tool to subjectively score severity of symptoms that are related to this pathology (Appendix A). This study aimed to adapt and validate the ETDQ-7 questionnaire in Greece to ensure correct and efficient use in the outpatient setting (Appendix B). The ETDQ-7 was translated into the Greek language following appropriate methodology. Data for the main study were collected from a sample of 75 Greek patients diagnosed with ETD as well as 25 patients that did not have ETD and who served as a control group. The participants completed the adapted ETDQ-7 questionnaire and underwent a clinical examination that was statistically correlated with their ETDQ-7 answers. Face and content validity were confirmed and the questionnaire was found easy to administer and to be completed by our patients. Test-retest reliability revealed similar internal consistency for the questions and good correlation between individual items and total score. Discriminative validity confirmed statistically significant difference between the two patient groups to ensure that the Greek version of ETDQ-7 is useful to confirm the diagnosis. The Greek version of the ETDQ-7 is safe and efficient to use among a variety of investigation methods for the diagnosis of ETD in the Greek speaking population.

The production of oxygenated bio-additives for traditional fuels represents a key challenge due to the depletion of fossil fuels in the next future and their contribution to environmental pollu-tion. In this context, the present study considers the synthesis of different mixtures of 1-hexanol/hexyl hexanoate produced through the catalytic hydrogenation of hexanoic acid, a car-boxylic acid obtainable from the fermentation of a wide variety of waste biomasses. In particu-lar, crude hexanoic acid deriving from the fermentation of grape pomace, an abundant Italian agrifood waste, has been taken into consideration. The reaction was carried out with the com-mercial 5 wt% Re/γ-Al2O3 catalyst, whose acidity allowed the tuning of the reaction selectivity towards the preferential formation of hexyl hexanoate instead of 1-hexanol. As consequence, the tunable composition of the obtained 1-hexanol/hexyl hexanoate mixtures was leveraged for en-gine applications, thus allowing studying each component influence on the Diesel engine per-formances and verifying their synergistic effects. The engine experimental activity highlighted that both 1-hexanol and hexyl hexanoate, as well as their mixtures, can be used in Diesel engine with a commercial Diesel fuel up to high loadings (20 vol%) without altering engine perfor-mances and significantly lowering soot and CO emissions by more than 40%.

Authors: Ren Hongtao , Lan Mu
Published: September 2023

Thermal fluctuations in two-dimensional (2D) isotropy systems at non zero finite temperatures can destroy the long-range (LR) magnetic order due to Mermin-Wanger theory. Interestingly, the magnetic anisotropy related to spin-orbit coupling (SOC) could stabilize magnetic order in 2D systems. Recently, 2D FexGeTe2 (3≤x≤7) with high curie temperature (TC), as a typical 2D van der Waals metallic ferromagnet, has not only made significant progress in synthetic methods and controlling ferromagnetism (FM), but also actively explored many device applications. In this Review, we introduce six experimental methods, ten ferromagnetic modulation strategies, and three spintronic devices of 2D FexGeTe2 materials. Overall, we have outlined the challenges and potential research directions in this field.
How Can We Compare CI Systems across Manufacturers? A Scoping Review of Recent Literature
Authors: Tzvi-Minker Elinor , Keck Andreas
Published: September 2023

Electric stimulation via a Cochlear Implant (CI) enables people with severe to profound sensorineural hearing loss to regain speech understanding and music appreciation and thus allowing them to actively engage in social life. Three main manufacturers (Cochlear, MED-EL and Advanced Bionics “AB”) have been offering CI systems, thus challenging CI recipients and Otolaryngologists with a difficult decision, as currently no comprehensive overview or meta-analyses on performance outcome following CI implantation is available. The main goal of this scoping review is to provide evidence that data and standardized speech and music performance tests are available for performing such comparisons. To this end, a literature search was conducted to find studies that address speech and music outcomes in CI recipients. From a total of 1592 papers, 188 paper abstracts were analyzed and 147 articles were found suitable for examination of full text. From which, 42 studies were included for synthesis. A total of 16 studies used the consonant-nucleus-consonant (CNC) word recognition test in quiet at 60db SPL. We found that aside from technical comparisons, only very few publications compare speech outcomes across manufacturers of CI systems. Evidence suggests though, that these data are available in large CI centers in Germany and US. Future studies should therefore leverage large data cohorts to perform such comparisons that could provide critical evaluation criteria and assist both CI recipients and Otolaryngologists to make informed performance-based decisions.

Introduction: Breast cancer affects worldwide almost 1.5 million women below the age of 45 years each year. Many of these women will be advised to undergo adjuvant chemotherapy to minimize the risk of death or recurrence of the tumor. For these patients, chemotherapy is a known cause of infertility, as it can damage primordial follicles which can lead to early menopause or premature ovarian insufficiency. This systematic review aims to synthesize the current evidence of the most suitable treatments for fertility preservation.
Methodology: This review is performed following the PRISMA guidelines. The authors conducted an extensive search from the last 15 years. Relevant studies were pursued in PubMed, Embase and the Cochrane Library up until the July 31, 2023. A total of 7 eligible studies were identified.
Discussion: The most suitable treatments for fertility preservation in young patients, is the temporary suppression with luteinizing hormone-releasing analogs, while the patient undergoes chemotherapy and cryopreservation. For cryopreservation, the physicians might deem it necessary to either cryopreserve ovarian tissue taken from the patient before any treatment or cryopreserve embryos/oocytes. Cryopreservation of oocytes and/or embryos is the most effective solution for fertility preservation in women of reproductive age, who have sufficient ovarian reserve and are diagnosed with breast cancer, regardless of the histological type of the tumor. Since approximately 50% of young breast cancer patients are interested in becoming pregnant right after completion of therapy, the evolution and development of fertility preservation techniques promise to be very exciting.

Published: September 2023

Running is a basic form of human locomotion and one of the most popular sports worldwide. While the leg biomechanics of running have been studied extensively, few studies have focused on the upper-body movement. However, an effective arm swing and longitudinal rotation of the shoulders play an important role in running efficiency as they must compensate for the longitudinal torques generated by the legs. The aim of this study is to assess the upper-body rotation using wearable inertial sensors and to elucidate its relation to energy expenditure. Eighty-six junior elite middle and long-distance runners (37 female, 49 male) performed an incremental treadmill test with sensors attached on both shoulders, tibiae and the sacrum. Mean and total horizontal shoulder and pelvis rotation per stride were derived while energy costs were determined using respiratory gas analysis and blood sampling. Results show that shoulder and pelvis rotation increase with running speed. While shoulder rotation is more pronounced in female than in male runners, there is no sex difference for pelvis rotation. Energy cost of running and upper trunk rotation prove to be slightly negatively correlated. In conclusion, upper body rotation appears to be an individual characteristic influenced by a sex-specific body mass distribution.
A Modest Contribution to the Riemann Hypothesis Using the Poincaré Index
Authors: Oliveira Hime
Published: September 2023

This work uses a new approach to investigate the Riemann hypothesis, drawing conclusions about its trueness. It is based on the more general method presented in a very recent publication, by the same author, showing in detail how to ap- proach that very well-known and interesting problem. This is achieved by means of the theory of dynamical systems (Poincaré index associated to equilibria of 2-dimensional systems) and the study of the zeros of the Dirichlet eta function, defined by a Dirichlet series. By using the well-known fact that the zeros of the eta function would include all zeros of the Riemann zeta function in the (open) critical strip, excluded the critical line, (0,1/2) ∪ (1/2,1) × (−∞,∞), the development proceeds using only the eta function. In addition, the open and simply connected region (1/2,1) × (0,∞) is used along the text, taking into account the symmetries of zeros of the functions under analysis in the critical strip. The basic line of proof is to find the mathematical expression for the Poincaré index of the vector field associated to the eta function, assuming the existence of a zero of the eta function outside the critical line (in (1/2,1) × (0,∞)), and investigating the resulting unfoldings. Eventually, an inconsistency occurs and the proof ends by contradiction.
Chilean Student Teachers’ Willingness to Learn with Gamified Systems
Authors: Saavedra Esteban Guillermo
Published: September 2023

In recent years, the use of gamified systems in education has increased due to the growing empirical evidence of their usefulness in improving motivation and participation in learning processes. In order to take advantage of the opportunities for improvement in education presented by gamification, plus the decision to create gamified systems in higher education, this article investigates the willingness of student teachers to learn with gamified systems. The research method is quantitative with validated instruments to measure: 1) student perception of gamification; 2) player profile; and 3) screen time, with an n=569 student teachers from the fifteen regions of Chile. The results show that students prefer to learn with gamified systems than in a traditional way with a significant difference (Wilcoxon z= -18.86, p < 0.01). There are significant positive and negative relationships in correspondence with the Gamer Profile. However, as a finding, a negative relationship was found between the number of hours spent playing video games and the perception of learning through gamified systems. In conclusion, Chilean student teachers present a favorable disposition to teacher training with gamified systems. However, the disposition varies in relation to the number of hours spent playing video games.
Optimal Predictive Torque Distribution Control System to Enhance Stability and Energy Efficiency in Electric Vehicles
Authors: Mousaei Arash , Naderi Yahya
Published: September 2023

In this study, a novel two-layer control scheme aimed at enhancing the dynamic performance of a nonlinear vehicle through the utilization of an optimal control approach grounded in predictive control principles is presented. The first layer of our control system focuses on the computation of an optimized rotational torque that ensures lateral dynamic stability. This torque is subsequently translated into differential forces acting on the wheels, employing the inverse tire model to derive the desired longitudinal slips. These slip values are then transmitted to the second layer of our control system. In the second layer, the electric motors associated with the vehicle's wheels dynamically adjust the input torque to accurately track the desired slip, thereby ensuring the overall stability of the electric vehicle. In view of the paramount importance of energy consumption in electric vehicles, we adopt optimal control strategies to substantially minimize battery utilization. To this end, careful selection of appropriate weighting coefficients in the control laws enables us to maintain the electric motors within their permissible operational range while simultaneously minimizing battery energy consumption for desired slip tracking. Extensive simulation results validate the effectiveness of our proposed control system in proficiently managing nonlinear effects and safeguarding the vehicle's stability.
