Cryptocurrencies represent a new form of property that exists only on the Internet. The first cryptocurrency to appear on the global market was Bitcoin, and its appearance is linked to the first financial crisis in 2008. The market capitalization of Bitcoin grew very quickly and in 2017 reached the highest capitalization in history (334 billion US dollars). Later, there was an expansion of new cryptocurrencies, of which there are currently over 1500 (e.g. Ethereum, Tether, BNB, USD Coin, etc.). The emergence of cryptocurrencies as a new concept affects the change in the perception of payments and money as a means of payment in general. The development of the global cryptocurrency market is indeed rapid and dynamic, and it is becoming an increasingly popular method of payment. Since the emergence of cryptocurrencies is not related to central banks, the need to change the classical systems and economic policies of countries is also expressed. The dynamic development of the mentioned market takes place in parallel with the development of information technologies, so there is a trend of capital outflow from classic capital markets to emerging global cryptocurrency markets. The question arises of the survival of traditional banks in the future, as more users trust cryptocurrencies. Global cryptocurrency markets are expected to expand more and more in the future. The paper will analyze the development of the global cryptocurrency market based on a sample of five of the most significant cryptocurrencies today.

In multi-attribute group decision-making (MAGDM), the attributes can be placed into independent groups based on their properties through partitioning. First, the partitioned dual Hamy mean (PDHM) operator is introduced, along with its essential properties. This operator integrates these separate groups while preserving the relationships between the attributes within each group. Furthermore, the partitioned Hamy mean (PHM) and the PDHM operators are also constructed in the generalized orthopair fuzzy environment, namely the q-rung orthopair fuzzy PHM (q-ROFPHM), the q-rung orthopair fuzzy PDHM (q-ROFPDHM), and their weighted forms. Their essential properties are verified to ensure the validity of the proposed aggregation operators (AOs). Subsequently, a new MAGDM approach is developed, employing the proposed AOs. The MAGDM problem of selecting the best person is examined. Moreover, the research includes a sensitivity analysis in three directions and a comparative analysis of the proposed MAGDM approach with five different approaches. The findings indicate that applying attribute partitioning in the proposed approach mitigates the adverse impact of irrelevant attributes, leading to more feasible and reliable outcomes. Additionally, a practical case study focuses on selecting a suitable industry for investment among the five available options. This case study demonstrates the approach’s effectiveness by considering five distinct qualities and results that make the Internet industry the best place to invest. Furthermore, a comparative analysis with four similar papers is also performed, indicating that the developed method’s results are more reliable and consistent.

The psychophysical preparation program for pregnant women includes physical exercises and theoretical lectures aimed at preparing the pregnant woman for childbirth and that the benefits far outweigh the risks. Exercise is an essential element of pregnancy, and OB-GYNs and other obstetric care providers should encourage their patients to continue or begin exercise. The aim of this work is to understand the impact of psychophysical preparation of pregnant women on health during and after pregnancy, birth outcomes and postpartum recovery. Twenty scientific research papers/articles including 5517 respondents were reviewed, based on databases: Web of Science, EBSCO, Scopus, Medline, PubMed, ScienceDirect, Google Scholar, and others. Works published from 2017-2022 were reviewed. The results of this study show that pregnant women who attended the program of psychophysical preparation for childbirth had a chance to experience childbirth in a more beautiful light, to be prepared, so that they would go to the maternity hospital with less fear, how to use breathing techniques during childbirth, and how to have the easiest and most beautiful childbirth without the use of drugs and interventions. Pregnant women had significantly more positive outcomes of childbirth as well as postpartum recovery and mental health. Psychological support and education have positive outcomes on the mental health of pregnant women because they reduce fear of the unknown and reduce the risk of postpartum depression. Higher rates of intact perineum, reduction of episiotomy and less damage of perineal tears are recorded. The preparation itself significantly affects the outcome of the test subjects’ births, where vaginal births are much more common, and the rate of instrumental methods of birth and caesarean section is reduced. A positive outcome was recorded during postpartum recovery.

In this paper, a novel method for the double heat treatment of ductile iron was applied. Ten sets of specimens (three specimens in each set) of ductile cast iron (DCI) containing 0.51% wt. Cu were prepared and converted to austenitic ductile iron. All specimens were austenitized at 850 °C for 60 min and annealed at 420 °C, 331 °C and 250 °C for 120, 68 and 30 min, respectively. Five sets of samples were then annealed at 500 °C for 60 min, creating a novel double heat treatment process for annealing. Finally, all specimens were slowly cooled in air at ambient temperature. Tensile strength, hardness and elongation were measured in all specimens to compare the specimens with and without subsequent tempering. A microstructural analysis was also performed, which showed that the microstructure changed for the specimens that were subsequently tempered with. The results show that specimens with subsequent tempering have slightly higher hardness, a small decrease in tensile strength and significantly higher elongation. In addition, specimens with subsequent tempering exhibit more uniform mechanical properties compared to specimens without subsequent tempering. The use of neutron beam techniques was proposed to further characterize the newly formed microstructure after subsequent tempering.

Contemporary neighborhood livability differs across countries due to implementation of sustainable policies within the building sector. This paper aims to showcase these differences among Germany, Croatia, and Bosnia and Herzegovina through a comparative case study analysis of two contemporary housing developments from each country. Representative neighborhoods from the aforementioned countries that were selected for analysis were located in Munich, Rijeka, and Sarajevo. The residential environment livability analysis method was used in order to pinpoint and compare results of each of these cases, and to assess their livability. The highest number of livability criteria among analyzed cases were found in Munich, while the lowest were found in Sarajevo. The conclusion is that this is happening due to German authorities actually implementing sustainable building standards in housing development prescribed by sustainability policies, while the authorities of Bosnia and Herzegovina completely, and Croatian authorities partially, go around these policies and bend to the will of investors, regulating residential urban development to the detriment of end users.

BACKGROUND: The ADAMTS7 locus was genome-wide significantly associated with coronary artery disease. Lack of the ECM (extracellular matrix) protease ADAMTS-7 (A disintegrin and metalloproteinase-7) was shown to reduce atherosclerotic plaque formation. Here, we sought to identify molecular mechanisms and downstream targets of ADAMTS-7 mediating the risk of atherosclerosis. METHODS: Targets of ADAMTS-7 were identified by high-resolution mass spectrometry of atherosclerotic plaques from Apoe−/− and Apoe−/−Adamts7−/− mice. ECM proteins were identified using solubility profiling. Putative targets were validated using immunofluorescence, in vitro degradation assays, coimmunoprecipitation, and Förster resonance energy transfer–based protein-protein interaction assays. ADAMTS7 expression was measured in fibrous caps of human carotid artery plaques. RESULTS: In humans, ADAMTS7 expression was higher in caps of unstable as compared to stable carotid plaques. Compared to Apoe−/− mice, atherosclerotic aortas of Apoe−/− mice lacking Adamts-7 (Apoe−/−Adamts7−/−) contained higher protein levels of Timp-1 (tissue inhibitor of metalloprotease-1). In coimmunoprecipitation experiments, the catalytic domain of ADAMTS-7 bound to TIMP-1, which was degraded in the presence of ADAMTS-7 in vitro. ADAMTS-7 reduced the inhibitory capacity of TIMP-1 at its canonical target MMP-9 (matrix metalloprotease-9). As a downstream mechanism, we investigated collagen content in plaques of Apoe−/− and Apoe−/−Adamts7−/− mice after a Western diet. Picrosirius red staining of the aortic root revealed less collagen as a readout of higher MMP-9 activity in Apoe−/− as compared to Apoe−/− Adamts7−/− mice. To facilitate high-throughput screening for ADAMTS-7 inhibitors with the aim of decreasing TIMP-1 degradation, we designed a Förster resonance energy transfer–based assay targeting the ADAMTS-7 catalytic site. CONCLUSIONS: ADAMTS-7, which is induced in unstable atherosclerotic plaques, decreases TIMP-1 stability reducing its inhibitory effect on MMP-9, which is known to promote collagen degradation and is likewise associated with coronary artery disease. Disrupting the interaction of ADAMTS-7 and TIMP-1 might be a strategy to increase collagen content and plaque stability for the reduction of atherosclerosis-related events.

The growing awareness of environmental sustain-ability has led to new investments in the field of electric vehicles. One of the most expensive and important components of electric vehicles are their batteries, with battery management systems (BMS) being responsible for their control. New regulations, such as those of the European Union, aim to introduce battery passports as a way to track battery lifecycle from manufacturing, over second-life use, to recycling. Given the vast amount of data generated during the lifecycle of a battery, the current research is focused on combining BMS with cloud connectivity. However, not much research has yet been done in the area of BMS cloud security and secure data logging. To address this gap, we propose a novel solution for secure BMS data acquisition for on-premise and cloud environments. In this paper, we make two main contributions: a secure data structure for BMS logging and a secure architecture for transferring BMS data from its source to cloud and end systems. We demonstrate the feasibility of the design by developing a prototype with real components and evaluate it in terms of security and performance.

Abstract Migration’s impact spans various social dimensions, including demography, sustainability, politics, economy, and gender disparities. Yet, the decision-making process behind migrants choosing their destination remains elusive. Existing models primarily rely on population size and travel distance to explain the spatial patterns of migration flows, overlooking significant population heterogeneities. Paradoxically, migrants often travel long distances and to smaller destinations if their diaspora is present in those locations. To address this gap, we propose the diaspora model of migration, incorporating intensity (the number of people moving to a country), and assortativity (the destination within the country). Our model considers only the existing diaspora sizes in the destination country, influencing the probability of migrants selecting a specific residence. Despite its simplicity, our model accurately reproduces the observed stable flow and distribution of migration in Austria (postal code level) and US metropolitan areas, yielding precise estimates of migrant inflow at various geographic scales. Given the increase in international migrations, this study enlightens our understanding of migration flow heterogeneities, helping design more inclusive, integrated cities.

Future vehicular communication systems will extend deployed frequency bands from sub-6 GHz to millimeter wave (mmWave). To investigate different propagation effects between sub-6 GHz and mmWave bands in high-mobility scenarios, we proposed a suitable testbed setup to compare these two bands in a fair manner. Experiments conducted using the proposed testbed provide realistic results, but they are only usable if they can be faithfully reproduced. To quantify the reproducibility of the proposed testbed, we perform channel measurements at center frequencies of 2.55 GHz and 25.5 GHz at a velocity of 50 km/h. We investigate the influence of antenna pattern, time between measurements, signal-to-interference-and-noise ratio (SINR) and signal bandwidth on the reproducibility in terms of the channel correlation.

This paper will problematize a teaching methodological approach to the novel Skretnice, in which the students’ communication competencies are put in the foreground. This paper tries to show how interpretation still occupies a special position in the modern teaching methodology of teaching literature by connecting the modern teaching methodological models and students’ needs. In the process of the teaching methodological processing of the novel Skretnice by Jasmina Musabegović, we try to combine the elements of various methodical approaches: interpretation, a problematic, open teaching methodological approach. The goal is to elaborate a reading strategy and development of language skills/competencies: reading, speaking, listening and writing. The novel will be set as a literary template in the function of developing fundamental students’ competencies, in which a teaching methodological interpretation of the novel will be further developed. We will direct the students’ activities towards independent reading, research and writing about the topics and problems raised by the novel and its openness for cross-subject correlations.

This paper uses examples of essay interpretations by Enes Duraković, who are at the very top of Bosnian and Herzegovinian literary critical thought, to show how this literary and scientific genre can be actualized in literature teaching. Essay interpretations by Enes Duraković, especially one of the most significant Bosnian and Herzegovinian poets, can be a good incentive for pupils and students to develop basic communication skills, reading habits and abilities, as well as an example for practicing essay expression. The paper points to the well-known facts that the essay is a neglected literary and scientific genre in literature teaching. The essay is a hybrid genre, located between the subjective literary and artistic and scientific fields. It is precisely such a poetic character that enables the representation of essays in various methodological approaches, from analytical-interpretative to more complex methodological systems: problem-based, correlation-integration and open approach. Using the examples of Duraković’s essay-interpretative approach to the poetry of Muse Ćazim Ćatić, Skender Kulenović, Mako Dizdar, we will show how an essay can be a good motivation for reading literary texts, in reading lessons, and as an introduction to a lesson about a writer or literary historical period.

The purpose of this paper is to show how the elements of oral literature interpolate in the contemporary literature for children and youth of the prominent Bosnian-Herzegovinian authors Alija Isaković and Ljubica Ostojić.Firstly, this Paper theoretically elaborates on the presence of the elements of oral literature in the literature for children and youth. These two different literary directions touch each other at their roots, and in the contemporary interpolation, they exist parallelly in the genre re-semanticization of the elements of oral literature. Following theoretical postulates of the most prominent authors from the South-Slavic Interliterary Community in the field of researching oral literature and literature for children and youth, we will show how the linguistic-stylistic heritage is re-interpreted through the traditional oral literary forms in the texts of contemporary authors, and how the elements of orality appear in new narrative structures- short stories and fairy tales of a new type. We will show how the rhetorical and rhythmical values of a text spill over in linguistic audacity, and how old oral structures; folk songs, and folk tales are narratively defamiliarized, deconstructed, and parodied.

This Paper starts from the fact that the literature for children and youth is traditionally burdened by pedagogizing, dominance of adults’ desires, censorship and that there are still not enough topics which are important for children and youth, because many such topics remain taboo. Adults, who normally determine contents and norms in this literature, hypocritically remain silent about the topics that concern those who primarily should read this part of literature. The authors consciously avoid the topics that talk about death, various deviations such as family break-up, parents’ divorce, alcohol, drugs, children in exile, and other „hard“, traumatizing topics. However, the traditional canon changes over time, as we will show with the examples from Lijeve priče by Alija Isaković, the Bosnian-Herzegovinian „prose in jeans“ and Alen Mešković’s novel. Although the attitude towards taboo topics in the literature for children has changed to some extent, there are still not enough topics which are marginal and tackle taboo, but children and youth encounter them in their lives. The dominant view is still that it is better to tacitly bypass these topics, because each change is conditioned by the social situation. Changing attitudes towards taboo topics always implies an author’s willingness for opening new polemics in society. At the end, the Paper concludes that bad examples dominate in literature as well as in life. The oldest example of this is Aesop’s fables, which teach children and adults. Because of that, as well as the fact that the modern times in lives of children and youth change the attitude towards traditional taboo topics, authors and society are expected to more flexibly accept changes which imply a different attitude towards the real interests of children and youth.

Hardware channel emulators are essential for developing and testing transceiver prototypes in laboratory settings. They should be able to monitor the dynamic motion of the mobile terminal. This paper presents a narrowband Multiple-Input Multiple-Output (MIMO) channel emulator implemented on Field-Programmable Gate Array (FPGA). The proposed emulator is based on Non-Line-of-Sight (NLoS) non-isotropic scattering with arbitrary motion dynamics of the mobile terminal. Its standalone hardware architecture ensures the flexibility and scalability of further hardware realization. Our proposed emulator is validated by comparing the emulated statistics of the channel gain against simulated results under a circular antenna trajectory. The Probability Density Function (PDF) of the fading envelope is observed to perfectly match the theoretical Rayleigh distribution(stationary channel) and the auto-correlation function(non-isotropic scattering) also shows a close agreement. The successful alignment of the eigenvalue of the channel gain matrix indicates our proposed emulator can perform correct MIMO characteristics.
