We use simplicial complexes to model simple games as well as weighted voting games where certain coalitions are considered impossible. Topological characterizations of various ideas from simple games are provided, as are the expressions for Banzhaf and Shapley-Shubik power indices for weighted games. We calculate the indices in several examples of weighted voting games with unfeasible coalitions, including the U.S. Electoral College and the Parliament of Bosnia-Herzegovina.

Global urbanization is advancing, and with it, the densification of cities. Due to increased sealing of open spaces and the re-densification of existing urban settings, green spaces in the city are becoming scarcer. At the same time, greening within the urban fabric is known for its positive effects on the environment and decisively counteracts the urban heat effect. This study deals with the benefits of green façades for the environment as a cooling measure. Two façade greening systems, one trough and one cassette system, consisting of curtain wall elements with a basic metal structure, installed at a south-facing outdoor wall of a school building in Vienna, Austria, were taken under metrological examination. In order to evaluate the cooling effect caused by evapotranspiration, the amount of water evaporated was calculated using the difference of inflow and outflow. Furthermore, the surface temperatures of the greened and non-greened walls were measured to display the influence of the interaction of shading and evapotranspiration on the surrounding microclimate. The investigated vertical greening system with an area of 58 m2 has an average evaporation capacity of 101.38 L per day in the summer. The maximum surface temperature difference was measured to be 11.6 °C.

Palliative care is an approach to the comprehensive care of a patient suffering from a chronic, incurable disease when the curative methods of treatment have been exhausted.

When developing products or performing experimental research studies, the simulation of physical or logical systems is of great importance for evaluation and verification purposes. For research-, and development-related distributed control systems, there is a need to simulate common physical environments with separate interconnected modules independently controlled, and orchestrated using standardized network communication protocols.The simulation environment presented in this paper is a bespoke solution precisely for these conditions, based on the Modular Automation design strategy. It allows easy configuration and combination of simple modules into complex production processes, with support for individual low-level control of modules, as well as recipe-orchestration for high-level coordination. The use of the environment is exemplified in a configuration of a modular ice-cream factory, used for cybersecurity-related research.

This paper presents an overview of advances in estimation of the biofouling state of fish cages as a part of the HEKTOR (Heterogeneous Autonomous Robotic System in Viticulture and Mariculture) project. Firstly, the developed framework for biofouling estimation is shown and explained in brief. A method using k-means clustering for labeling images of fish cages is outlined. It is followed by results of machine learning approaches for automatic inferring of semantic meaning of pixels in an image trained on a recorded dataset using said outlined method. Furthermore, a brief overview and results of contour detection on images classified by trained machine learning models are given. Moreover, a method of feature-based monocular camera distance estimation constrained by assumptions of the viewing angle is presented. All mentioned methods and algorithms fit together in order to produce an estimation of how biofouled the observed net is. The successfulness of the estimation depends on the viewing conditions while filming the cages. In good conditions the results are satisfactory and could be used by industrial fisheries in place of human labour. All the developed algorithms are fast enough so that the entire process from start to finish takes less than 1 second.

This paper analyzes the key determinants of the quality of preschool education in Bosnia and Herzegovina. Based on the analysis of recent data, the paper indicates the status and development trends in this regard in the last decade. Although preschool education in Bosnia and Herzegovina has a long tradition, it is facing a number of challenges, mostly arising from the arrangement of the state system and post-war transition processes which have significantly impoverished this level of education. Therefore, the main goal of this paper is to point out the recent public policy efforts made in the attempt to ensure the quality of preschool education in Bosnia and Herzegovina, as well as the effects that are being achieved in this regard. Since quality can be approached from the aspects of structure and process, the elementary structural and process dimensions of preschool education will be taken as units of this analysis. Conceptualizing the results of this analysis, the status and quality of preschool education in Bosnia and Herzegovina will be positioned through an orientation towards the European framework for the quality and development trends of preschool education in Europe.

The subject of this paper is the criminal-legal aspects of corruption in Bo- snia and Herzegovina. The author’s intention is to divert your attention and point out the legal and social specifics of corruption as legal and social phenomenon that under special attention of scientific, expert and gene- ral public for a reason. Respectfully, there is no area of human action or interaction that is immune to corruption. However, the institutional re- action of state to this criminality must be adequate and proportional to the needs of research and evidence in order to achieve desired results of criminal judiciary. Special attention is directed to the problem of defini- tion and understanding corruption with all its complex dimensions and the inability to coordinate one universal and comprehensive definition of this term. Also, this essay emphasizes problems of complexity of revealing the existence of these criminal acts and the aspect of verifying, i.e. proving the existence of these corruptive actions, while appreciating restrictive law conditions, materials and process.

Predmet ovog rada su krivično-pravni aspekti korupcije u Bosni i Herce- govini, te intencija autora da skrenu pažnju i ukažu na određene pravne i društvene specifičnosti korupcije, kao pravnog i društvenog fenomena koji sa razlogom zavređuje posebnu pažnju naučne, stručne i opšte jav- nosti. Uvažavajući da ne postoji ni jedna oblast ljudskog djelovanja koja je imuna na korupciju, državna institucionalna reakcija na ovaj krimi- nalitet mora biti adekvatna i srazmjerno potrebna realnim otkrivačkim i dokaznim potrebama u cilju postizanja adekvatnih rezultata krivičnog pravosuđa. U vezi s naprijed navedenim, posebna pažnja je usmjerena na problem definisanja i shvatanja korupcije, cijeneći njegovu složenost i nemogućnost usaglašavanja jedne univerzalne i sveobuhvatne defini- cije ovog pojma. Takođe, u radu su apostrofirani problemi koji se odno- se na kompleksnost otkrivanja postojanja ovih krivičnih djela kao i na aspekt utvrđivanja, odnosno dokazivanja koruptivnih krivičnih djela, cijeneći restriktivne zakonske uslove materijalne i procesne prirode.

Peer violence and school safety have always been relevant topics in society. After the tragedy that occurred at the “Vladislav Ribnikar” Elementary School in Belgrade, these issues have gained special significance and received great public attention. The loss of innocent children’s lives has prompted a reassessment of past practices in schools regarding school safety. The aim of this paper is to analyze problems related to peer violence in the Republic of Srpska. Subsequently, the authors address the issue of school safety in a broader context and, finally, discuss the justification for educating students in the field of security culture in primary and secondary schools in the Republic of Srpska.

Enteric viruses are commonly found obligate parasites in the gastrointestinal (GI) tract. These viruses usually follow a fecal-oral route of transmission and are characterized by their extraordinary stability as well as resistance in high-stress environments. Most of them cause similar symptoms including vomiting, diarrhea, and abdominal pain. In order to come in contract with mucosal surfaces, these viruses need to pass the three main lines of defense: mucus layer, innate immune defenses, and adaptive immune defenses. The following atypical gastrointestinal infections are discussed: SARS-CoV2, hantavirus, herpes simplex virus I, cytomegalovirus, and calicivirus. Dysbiosis represents any modification to the makeup of resident commensal communities from those found in healthy individuals and can cause a patient to become more susceptible to bacterial and viral infections. The interaction between bacteria, viruses, and host physiology is still not completely understood. However, with growing research on viral infections, dysbiosis, and new methods of detection, we are getting closer to understanding the nature of these viruses, their typical and atypical characteristics, long-term effects, and mechanisms of action in different organ systems.

Abstract Surgical treatment and formation of a stoma can be lifesaving for colorectal cancer patients. However, the quality of life is often impaired in patients with stoma. The goal of this study is to determine the quality of life of patients with stoma and cancer, and the relationship between the quality of life and characteristics of these patients. The study was conducted from 2018 to 2020 and included a total of 64 patients of both sexes with colorectal cancer and temporary or permanent stoma. The European Organization for Research and Treatment of Cancer with Quality of Life Questionnaire (EORTC QLQC29-30) and the anonymous WHO Quality of Life Questionnaire SF-36 were used for self-assessment of quality of life. Our study included 39 (61.0%) men and 25 (39.0%) women. 24 patients (37.5%) had colostomy, 14 patients (21.9%) had ileostomy, and 26 patients (40.6%) underwent surgery for resection of colorectal cancer without stoma. A significant number of women were in the group of patients with a permanent stoma (p = 0.01). There was no statistically significant difference in the assessment of general health (p = 0.680) and quality of life (p = 0.721) during the past month in relation to gender. Patients without a stoma rated their general health better compared to those with stoma and the difference reached statistical significance (p = 0.035). There was no statistically significant difference in the assessment of quality of life between the group of patients with stoma and without stoma, as well as between the patients of different age groups. Patients with stoma rated their general health as worse, but not their quality of life.

Driven by significant improvements in architectural design and training pipelines, computer vision has recently experienced dramatic progress in terms of accuracy on classic benchmarks such as ImageNet. These highly-accurate models are challenging to deploy, as they appear harder to compress using standard techniques such as pruning. We address this issue by introducing the Correlation Aware Pruner (CAP), a new unstructured pruning framework which significantly pushes the compressibility limits for state-of-the-art architectures. Our method is based on two technical advancements: a new theoretically-justified pruner, which can handle complex weight correlations accurately and efficiently during the pruning process itself, and an efficient finetuning procedure for post-compression recovery. We validate our approach via extensive experiments on several modern vision models such as Vision Transformers (ViT), modern CNNs, and ViT-CNN hybrids, showing for the first time that these can be pruned to high sparsity levels (e.g. $\geq 75$%) with low impact on accuracy ($\leq 1$% relative drop). Our approach is also compatible with structured pruning and quantization, and can lead to practical speedups of 1.5 to 2.4x without accuracy loss. To further showcase CAP's accuracy and scalability, we use it to show for the first time that extremely-accurate large vision models, trained via self-supervised techniques, can also be pruned to moderate sparsities, with negligible accuracy loss.

Listeria je patogen prenosiv hranom i predstavlja veliku opasnost za ljudsko zdravlje. Teški su simptomi praćeni visokom stopom mortaliteta većinom prouzročeni L. monocytogenes. Bez obzira na politiku nulte tolerancije, rod Listeria je još uvijek prisutan u sirovim proizvodima i proizvodima spremnim za konzumiranje, predstavljajući veliku opasnost za zdravlje ljudi. Za sada još u bliskoj budućnosti ne postoje studije o kontaminaciji hrane vrstama Listeria u Bosni i Hercegovini. Ovim istraživanjem htjeli smo dobiti osnovne podatke o količini kontaminiranosti hrane ovim patogenom. U studiji je analizirano ukupno 238 uzoraka hrane, pri čemu su u 105 uzorka bile različite vrste sirove hrane te 133 uzorka hrane spremne za konzumaciju (gotove hrane). Od ukupno 238 uzoraka, 18 uzoraka je bilo pozitivno na Listeria vrste. Nakon izolacije i detekcije, konfirmacija pozitivnih izolata Listeria spp. je provedena pomoću biokemijskog kita API® Listeria.
