Recent trends in the development of autonomous vehicles focus on real-time processing of vast amounts of data from various sensors. The data can be acquired using multiple cameras, lidars, ultrasonic sensors, and radars to collect useful information about the state of the traffic and the surroundings. Significant computational power is required to process the data fast enough, and this is even more pronounced in vehicles that not only assist the driver but are capable of fully autonomous driving. This article proposes speed and accuracy improvement of traffic sign detection and recognition in high-definition images, based on focusing on different regions of interest in traffic images. These regions are determined with efficient and parallelized preprocessing of every traffic image, after which convolutional neural network is applied for detection and recognition in parallel on graphics processing units. We employed different “You Only Look Once” (YOLO) architectures as baseline detectors, due to their speed, straightforward architecture, and high accuracy in general object detection tasks. Several preprocessing procedures were proposed, to achieve real-time performance requirement. Our experiments using a large-scale traffic sign dataset show that we can achieve real-time detection in high-definition images with high recognition accuracy.

Background. The most common cause of early death in acute myocardial infarction with ST elevation are malignant heart rhythm disorders, generally occurring in the first four hours of myocardial infarction. The incidence of ventricular fibrillation is greatest in the early stage of the myocardial infarction, and sudden cardiac deaths occur most often in outpatient conditions. Case reports. This paper presents a patient whose first manifestation of coronary artery disease was myocardial infarction with ST elevation complicated by early ventricular fibrillation. Rapid measures of cardiopulmonal resuscitation enabled quick establishment of normal sinus rhythm. Primary percutaneous intervention was performed, with revascularization of artery responsible for acute myocardial infarction. In order to reduce ischemic brain damage, therapeutic hypothermia was applied since the patient was presented in post-reanimation coma. Conclusion. Better treatment of patients with cardiac arrest in outpatient conditions and faster revascularization of the infarct artery are crucial for a reduction of mortality in acute myocardial infarction.

Rad se bavi počecima znanstvenog promišljanja hrvatske književnosti u Bosni i Hercegovini te predstavlja biografska i biobibliografska istraživanja sedmorice autora, počevši od Filipa Lastrića u 18. do Tugomira Alaupovića u prvoj polovici 20. stoljeća. Promatramo kako su ovi autori razumijevali književnost i njezinu povijesnu dimenziju, osobito kako su pristupili osnovnim problemima povijesti književnosti kao što su definiranje korpusa, izbor pisaca, periodizacija, književnopovijesna interpretacija i vrednovanje te koja su rješenja ponudili. Analizira se i postupno napuštanje okvira biobibliografije te primjena složenijih književnopovijesnih pristupa.

Teaching sustainability and resilience on the level of both materials and structure is today's imperative for a more environmentally friendly tomorrow, but also for the enrichment of human life and preservation of historical structures. Re-examining sustainability in its reverence for pre-existing structures, conceiving projects by first taking inventory of what already exists, has become the starting point of defining research cases for students in the past few years at the Džemal Bijedić University of Mostar's Civil Engineering Faculty. The paper presents the approach developed and work done in the past several years, mainly within two subjects at the Civil Engineering Faculty. The developed methodological approach was based on the combination of the knowledge creation and case-based learning method. Case studies are always based on heritage buildings. The aim of the approach is to teach how to find an opportunity of doing more with existing structures, and argues their future use and possibilities for improvement, upgrade and re-use. Demolishment is a decision of easiness and has a major impact on the history and identity of the city and its community. Therefore, it is our task to search for various conservation approaches in order to preserve the city's layers and provide progress.

Mercury (Hg) has been listed as a global high priority pollutant by many international organizations due to its mobility and persistence in the environments and high toxicity to organisms. This research was conducted with the aims to determine: (i) total Hg content (THg) and its spatial distribution in sediments of river Tisa along the river course, (ii) possible sources of THg and (iii) degree of THg pollution in sediments from the river Tisa through different criteria. Total Hg in the sediments ranged from 0.07 to 0.49 mg kg-1, with mean ? S.D. value of 0.26 ? 0.10 mg kg-1. The highest mean value of THg (0.30 mg kg-1) was found in the lower stream, while the lowest (0.13 mg kg-1) was found in the tributary. According to Principal Component Analyses (PCA) strong positive loading of metals in all parts of the river Tisa is mainly controlled from the same sources. These sources are related to anthropogenic activities based on calculated Enrichment Factor (EF) values. Total Hg are higher than background value. According to the Republic of Serbia official standard, THg values of river Tisa sediments were within the range of maximum permissible values. Compared with National Oceanic and Atmospheric Administration (NOAA) guideline, 80.49% of sediment samples indicated that THg in the river Tisa sediments represented minimal and possible risk towards the living organisms. Integrating the results of pollution assessment, it could be concluded that THg in river Tisa sediments in Serbia demonstrates considerable contamination according to Geoaccumulation Index (Igeo), and Contaminant Factor (CF), and high pollution risk according to Potential Environmental Risk Index (PERI).

The sequential extraction procedure was applied for partitioning of metals in river sediments collected along the course of the river Tisa (Serbia). Eight elements (Sb, Sn, As, Cd, Cu, Hg, Pb and Zn) from twenty-one sampling site were analyzed using the modified BCR sequential extraction procedure in combination with ICP-OES. The results of sequential extraction, statistical analyses and calculation of EF and lithogenic and anthro?pogenic ratio of metals are similar. In the river Tisa sediments Sn, Cd, Hg, Pb and Zn are of anthropogenic origin, while As, Cu and Sb are of lithogenic and anthropogenic origin. The sediments from the river Tisa show high risk for Cd, medium risk for Hg and Zn, low risk for Sn, As, Cu and Pb, whereas Sb does not show the risk for the aquatic environment.

Cytochrome P450 3A4 is the most significant enzyme in metabolism of medications. Flavonoids are common secondary plant metabolites found in fruits and vegetables. Some flavonoids can interact with other drugs by inhibiting cytochrome P450 enzymes. Thus, the objective of this study was to determine inhibition kinetics of cytochrome P450 3A4 by flavonoids: acacetin, apigenin, chrysin and pinocembrin. For this purpose, testosterone was used as marker substrate, and generation of the 6β-hydroxy metabolite was monitored by high performance liquid chromatography coupled with diode array detector. IC50 values, inhibition constants, and rates of inhibition were determined. IC50 values ranged between 0.6 and 11.4 μM. The strongest inhibitor was chrysin (IC50 0.6 μM, inhibition constant 0.6 μM, inhibition rate constant 0.065 min–1, inhibition efficacy 0.108 min–1 μM–1). Compared to other flavonoids analyzed, chrysin’s inhibitory effect can be attributed to the hydrophobic nonsubstituted B ring, as well as rigidity of the structure. When foods rich in chrysin are consumed, e.g. honey and propolis, chrysin can cause food-drug interactions. Further in vitro studies are needed to determine the reactive intermediate responsible for inactivation of cytochrome P450 3A4 enzyme, as well as in vivo studies to determine possible clinical significance of this inhibition.

The influence of German language onto Croatian language has been going on for centuries. It was most intensive during the 19th century. Therefore we can find German loanwords all over Croatia. The focus of the research is put onto the presence of German loanwords in the carnival newspapers of Sinj in the time span from 1929 till 2015. The German loanword is presented in context in a corpus, contrastively analysed on the semantic level in the process of secondary adaptation, ie. the extention of meaning in a number and in a field.

The minimum wage, as a labour market policy with distributive impact, is widely debated in Bosnia and Herzegovina (BiH). This paper estimates the effect of increasing the minimum wage on poverty and income inequality in BiH, providing the first empirical evidence on the minimum wage in the country. Using data from the Household Budget Survey (HBS) for 2015, the effects of four changes (two per entity) in the minimum wage were simulated using the microsimulation model BiHMOD. First, the effect of the latest changes implemented in the previous period was calculated using the previous minimum wage level as the baseline. Second, the effect of recently proposed changes was simulated using the current level as the baseline. The findings suggest that increasing the minimum wage in BiH has a significant positive effect on poverty reduction, but a limited effect on the level of income inequality. The estimated effects were also calculated for different types of households. The results suggest that a single policy may have unexpected effects if other policies are not taken into account and harmonized accordingly. The findings provide empirical evidence for decision-makers and future policy debate, which is generally missing for this and similar policy issues in BiH.
