We consider the adaptive control problem for discrete-time, nonlinear stochastic systems with linearly parameterised uncertainty. Assuming access to a parameterised family of controllers that can stabilise the system in a bounded set within an informative region of the state space when the parameter is well-chosen, we propose a certainty equivalence learning-based adaptive control strategy, and subsequently derive stability bounds on the closed-loop system that hold for some probabilities. We then show that if the entire state space is informative, and the family of controllers is globally stabilising with appropriately chosen parameters, high probability stability guarantees can be derived.

Iron deficiency anemia (IDA) continues to pose one of the most significant challenges in maternal health, affecting nearly 40% of pregnant women worldwide according to the World Health Organization (2023).  Despite advances in obstetric screening, conventional diagnostic methods such as complete blood count (CBC) tests often fail to detect early or latent stages of anemia due to physiological changes associated with pregnancy.  This study introduces a robust machine learning framework integrating Extreme Gradient Boosting (XGBoost), and Conditional Tabular Generative Adversarial Networks (CTGAN) for the early detection of IDA in pregnant women. Our approach addresses the class imbalance inherent in clinical datasets and incorporates trimester-specific hematological adaptations.  Using 3,944 anonymized clinical records from ASA Hospital Sarajevo (January–July 2025), we evaluated model performance across hematological features commonly used in obstetric care. The optimized model achieved a precision of 100%, recall of 65.2%, specificity of 100%, and an AUC-ROC of 0.8686. Comparative analysis against conventional CBC screening, which reached only 40.5% sensitivity, demonstrated significant improvement in detection reliability. These findings demonstrate the potential of AI-enhanced diagnostics to support early detection of IDA in pregnant women, reduce missed diagnoses, and strengthen clinical decision-making. Further multi-center validation and integration of additional biomarkers are recommended to confirm generalizability.

During the early months of the COVID-19 pandemic, treatment protocols varied substantially among countries and even between hospitals. This study compared the clinical characteristics, management strategies, and outcomes of hospitalized COVID-19 patients treated in tertiary centers in Türkiye and Bosnia and Herzegovina. We retrospectively analyzed 1338 adults hospitalized with laboratory-confirmed SARS-CoV-2 infection: 657 patients in Tuzla (Bosnia and Herzegovina, June–December 2020) and 681 in İstanbul (Turkiye, April–May 2020). Demographic, clinical, and laboratory data, treatment details (including favipiravir use), need for invasive or non-invasive mechanical ventilation, and in-hospital mortality were extracted from medical records. Patients in Bosnia and Herzegovina were older (61.6 ± 14.4 vs. 56.9 ± 15.8 years; p < 0.001) and had longer hospital stays (9.0 ± 5.5 vs. 7.7 ± 6.1 days; p < 0.001). In the Bosnian cohort, leukocyte, neutrophil, platelet, ferritin, CRP, troponin, creatinine, AST, and ALT levels were significantly higher, whereas hemoglobin and D-dimer levels were lower. The need for ventilatory support was greater in Bosnia and Herzegovina (15.1% vs. 12.2%, p < 0.001), and overall mortality was higher (25.7% vs. 9.3%, p < 0.001). No mortality difference was observed between patients treated and not treated with favipiravir. Despite similar inclusion criteria, patients in Bosnia and Herzegovina exhibited more severe disease, greater organ involvement, and higher mortality than those in Turkiye. Favipiravir use did not influence survival. Inter-country comparisons highlight how differing patient profiles and treatment protocols may impact COVID-19 outcomes; however, interpretation should consider that the two centers contributed data from different phases of the 2020 pandemic, and that country-level differences in circulating variants, healthcare capacity, hospital strain, and evolving clinical guidelines may also have influenced the observed patterns.

Background Previous studies have shown that stimuli that another individual looks at are better remembered than stimuli that are not looked at, suggesting that joint attention improves memory. However, these previous studies have differed in the type of memory being tested and the type of content that is to-be-remembered: while effects of joint attention on long-term memory were tested with verbalizable stimuli, effects on working memory have only been tested with visual stimuli such as colour. Thus, the aim of the current study is to extend these previous findings and investigate whether joint attention improves working memory for verbalizable stimuli. Methods Participants were first presented with an image of a face with eyes that gazed either to the left or to the right, after which a grid of 4 letters (2x2) was shown. On half of trials, this grid with letters was shown in the same direction that was gazed at, and in the other half of the trials, in the other direction. After a retention interval (1000 ms), participants were shown a letter in the centre of the screen and asked to judge whether they have seen this letter as part of the grid shown before. Results Our results revealed that participants’ judgements about whether they had previously seen the letter was more accurate for letters that had been gazed at than letters that had not been gazed at. In contrast, participants’ reaction times were not influenced by whether the letter had been gazed at. Conclusions Our findings suggest that joint attention can improve working memory for verbalizable stimuli such as letters.

The primary objective of external fixation is to stabilize bone fractures, with the mechanical characteristics of the fixation system playing a critical role in shaping the biomechanical environment of the fracture and, consequently, the healing process. This study presents an experimental investigation of the stability of eight unilateral external fixation configurations applied to an open tibial fracture. The stiffness of each configuration was evaluated under axial compression, anterior–posterior (AP) bending, medial–lateral (ML) bending, and torsional loading. In addition, the effects of structural parameters—such as the number of half-pins, planarity of the configuration, and interfragmentary distance—on fixator stiffness and generated stresses were examined. The results revealed a linear relationship between applied load and both bone segment displacement and principal stresses. Biomechanical tests demonstrated that biplanar configurations provide sufficient stability for open tibial fractures, while simultaneously offering an optimal structural design for the fixation system. Moreover, the number of half-pins was identified as a statistically significant factor influencing configuration stiffness under axial loading and torsion, with biplanar configurations proving particularly effective in torsional scenarios. However, in AP and ML bending tests, neither configuration type nor any individual parameter produced statistically significant differences in bending stiffness. Interestingly, interfragmentary distance did not exert a statistically significant effect on configuration stiffness under any loading condition. Furthermore, neither configuration type nor the analyzed parameters had a notable influence on the principal stresses measured at the control points.

In this research, the impact of applications on improving urban logistics was examined using the example of the company EX, with an emphasis on the sustainability of its business. To conduct this research, expert decision-making was used. The model used ten criteria and eight applications. To incorporate uncertainty into this research, an intuitionistic fuzzy approach was used. Based on the obtained CC values, the criteria weights were determined using the SiWeC (Simple Weight Calculation) method, while the WASPAS (Weighted Aggregated Sum Product Assessment) method ranked the applications. The results showed that “Security and data protection” and “System reliability and stability” were the most important criteria, while Application 1 achieved the best results. These results were confirmed by the consistency analysis of the WASPAS method and the sensitivity analysis, which considered 30 scenarios.

OBJECTIVE To report two additional cases of glycogen-rich clear cell carcinoma (GRCC) of the breast - detailing their clinicopathologic features, immunophenotypes, and follow-up - and to provide an updated literature review since 2020. CASE REPORTS Two patients (66 and 52 years old) had GRCC confirmed morphologically and histochemically. Case 1 was ER-positive/HER2- positive (luminal B/HER2-positive) and was managed with surgery, followed by adjuvant chemotherapy, endocrine therapy, and anti-HER2 therapy (trastuzumab). Case 2 was triple-negative and received neoadjuvant chemoimmunotherapy (pembrolizumab- based) with marked pathologic tumor regression at resection. Both patients were disease-free at one and 12 months, respectively. CONCLUSIONS GRCC is heterogeneous and should not be regarded as a single clinicopathologic entity within invasive breast carcinoma of no special type or assumed to have a uniform prognosis. Management should be biomarker-guided, as illustrated by these cases. The role of targeted and immune therapies in GRCC warrants multi-institutional studies.

In the early stages of research on the genetics of human morphological traits, particular attention was given to the details of the physical complexities of the face. In this field, prominent focus was placed on the characteristics of the auricle, especially the types of the earlobe (lobulus auriculae). This paper presents the first data on the previously undescribed possibility of inheriting the ossified granules of the antihelix. Based on genealogical analysis of the presence/absence of the granule across five successive generations of a Bosnian family, evidence is provided for the autosomal recessive inheritance of this dimorphism.

Grammatical aspect informs us about the internal temporal contours of a situa tion. In other words, aspect provides information as to how the verbal action is to be regarded, whether it is complete, continuous, or iterative. Bosnian grammati calizes the binary system characteristic of Slavic languages that entails that verbs are marked for the perfective or the imperfective aspect. English, on the other hand, grammaticalizes the perfect and the progressive, which do not entirely cor respond to the perfective/imperfective aspectual opposition. Grammatical aspect is an obligatory category in Bosnian, whilst in English, verbs need not be mor phologically marked for aspect. Expectedly, studies report different processing patterns in sentences with aspectual violations in these two languages. It has been shown that native speakers of English do not show electrophysiological responses to violations of aspect, while native speakers of Bosnian show a clear sensitivity to aspectual violations immediately at the verb. Even though they detect aspectual violations already at the point of the verb in Bosnian, their L1, in this study we investigate whether university students of English process aspectual violations in English, their L2. More precisely, we conducted a self-paced reading study to ex plore whether Bosnian university students of English detect aspectual violations at the position of the verb or in adjacent positions during incremental sentence processing. Our results are in line with the previous findings on L1 processing of English aspect – English aspectual violations are not detected online during sen tence comprehension in L2 processing. However, there is an important difference. Unlike native speakers of English, Bosnian university students of English do not detect aspectual violations even after the sentence has been processed. Such re sults provide evidence for the Shallow Structure Hypothesis in L2 processing. We, therefore, compare our findings with other studies on grammatical aspect, con trast L1 and L2 processing, and discuss English and Bosnian grammatical aspect.

USB4 Version 2.0 is the first generation to adopt Pulse Amplitude Modulation-3 (PAM-3) signaling while increasing the data rate to 40 Gb/s, thus needing PAM-3 transceivers that can satisfy its various requirements. This paper presents the architectural choices and trade-offs in high-speed PAM-3 wireline transmitters. A quarter-rate clocking architecture is adopted to investigate the impact of different driver and Feed-Forward Equalizer (FFE) implementations on complexity, area, and power consumption across varying data rates. Three transmitter architectures are designed and simulated in 22 nm CMOS technology, following the standard as a guideline. Analog and digital FFE implementations are combined with voltage-mode, conventional and DAC driver implementations. All three designs employ a 4-tap FFE as required by the specification. Among them, the DAC-based design achieves the highest energy efficiency and smallest area, whereas the all-analog solution ranks second. The analog driver with digital FFE results in the most power and area consumption.

Geodetic survey is a comprehensive process for collecting both graphical and descriptive data related to real estate, primarily for the purpose of establishing cadastral records and land registration. The graphical data serve as the fundamental basis for creating various small-scale cartographic representations. Geodetic surveys in Bosnia and Herzegovina have been conducted twice. The first comprehensive systematic survey was carried out by the administration of the Austro-Hungarian Monarchy, covering the entire territory of Bosnia and Herzegovina at that time. The second comprehensive survey began after the end of World War II and lasted several decades, though not all of Bosnia and Herzegovina's territory was surveyed during this period. The result of the geodetic survey of Bosnia and Herzegovina during the rule of the Austro-Hungarian Monarchy was the creation of cadastral maps that did not include representations of relief features. Cadastral plans were produced at scales of 1:6250, 1:3125, 1:1562.5, and 1:781.25. The scale of the cadastral plan depended on the built-up density of the surveyed territory. The real estate data collected during this survey are referred to in Bosnian-Herzegovinian geodetic terminology by a unique name – the “old survey”. Conversely, the geodetic surveys conducted during socialist Bosnia and Herzegovina included, among other features, representations of the territory on cadastral plans created at scales ranging from 1:5000 to 1:500. These plans incorporated a separate layer depicting terrain elevation, which allowed for the creation of topographic-cadastral plans by overlaying these elevation layers onto cadastral maps. In Bosnian geodetic terminology, the data collected during this period are referred to as the “new survey”. Cadastral plans from both the old and new surveys are collectively referred to as large-scale map representations. From these representations, a multitude of small-scale map representations can be generated. Despite the availability of these data, it's notable that throughout the history of Bosnia and Herzegovina, the graphical depiction of the region has been portrayed on numerous small-scale cartographic representations created across various historical periods. After the completion of the geodetic survey of the settlement of Prusac, situated within the present-day municipality of Donji Vakuf, by the administration of the Austro-Hungarian Monarchy, a cadastral register and land register were established. The cadastral record from the land cadastre of the old survey served as the official cadastral record for several decades. However, the destruction of this register during the hostilities of the Second World War left the area of Prusac without a cadastral register. To maintain a record of real estate ownership, an evidentiary land cadastre was instituted for the Prusac area, utilizing archival lithographic copies of cadastral plans from the old survey as graphical bases. In the 1970s, an aerial photogrammetric survey of the municipality of Donji Vakuf, including the area of the settlement of Prusac, was carried out. Utilizing this data, the cadastral register of the new survey was established. Following the establishment of the cadastral register of the new survey, the use of the cadastral register from the evidentiary cadastre of the settlement of Prusac was discontinued. Evidentiary cadastre was established partially on the basis of the data of the old survey. It has been repealed, resulting in the discontinuation of the evidentiary cadastral register's use as an official cadastral record. However, to maintain the land register, “cadastral plans” from the evidentiary land cadastre were occasionally employed. After the establishment of the cadastral register of the new survey, the cadastral plans from this survey became the official graphic base for maintaining the cadastral register. Prusac, a city with a history spanning through several centuries, held significant importance following the Ottoman Empire's occupation of Bosnia and Herzegovina. During the Ottoman rule, Prusac emerged as a prominent location, notably recognized for the religious and cultural event known as Ajvatovica. Various localities within Prusac and its environs hold associations with this event. The focus of this paper is to examine the depiction of the Ajvatovica locality on both analog cadastral plans from the old and new surveys. Additionally, the research delves into locating and presenting Prusac on small-scale cartographic representations dating back to the Ottoman Empire era.

This paper explores both theoretical and practical dimensions of peacebuilding in post-conflict societies, with a specific focus on Bosnia and Herzegovina and the role of the High Representative, established by Annex 10 of the General Framework Agreement for Peace (Dayton Peace Agreement). By analysing the functioning of the Office of the High Representative (OHR), the study investigates the scope and limitations of the liberal institutionalist approach to peacebuilding, which dominated international intervention strategies in Bosnia and Herzegovina after 1995. The paper argues that classical institutional models failed to adequately respond to the fragmented political landscape and deep ethno-political divisions in Bosnia and Herzegovina, leading to a gradual transformation of the High Representative’s mandate from a coordinating body to a politically active institution with significant executive powers. The aim of this study is to examine the institutional evolution of the OHR and assess its contribution to state-building and peace preservation in Bosnia and Herzegovina, while also critically engaging with broader debates on the effectiveness of international peacebuilding in complex post-conflict environments. The research employs a qualitative methodology, including the analysis of primary documents (Annex 10, decisions of the OHR, legal acts), secondary sources (academic literature, international reports), and a case study approach based on a chronological review of the actions taken by High Representatives from 1995 to 2021. The analysis focuses on three core areas where the intervention of the High Representative had a decisive impact: (1) the imposition of binding decisions and laws in cases where domestic political actors failed to reach consensus; (2) judicial reforms and the annulment of rulings by domestic courts that were seen as contrary to the peace agreement; and (3) the dismissal of political officials deemed to be violating the Dayton Agreement or undermining the constitutional order. Findings indicate that this form of international tutelage contributed to short-term stabilization and institutional functionality but also raised concerns over democratic legitimacy and the limited ownership of domestic actors in the reform process. The theoretical framework links traditional liberal peacebuilding approaches with more recent critiques that emphasize the need for deeper local participation, long-term capacity-building, and context-sensitive governance. In this regard, the Bosnia and Herzegovina case illustrates the ambivalence of international interventions—balancing between ensuring stability and respecting sovereignty, and between delivering quick institutional fixes and fostering sustainable domestic governance. Scholarly and political critiques of the OHR’s role vary widely—from accusations of autocratic governance to acknowledgments of its necessity—thus exposing the ongoing tension between efficiency and legitimacy in international administration. The paper concludes that while the institution of the High Representative has played a critical role in maintaining peace and facilitating institutional development in Bosnia and Herzegovina, long-term sustainability requires a shift from external supervision to internal political consensus. The contribution of this research lies in its systematic analysis of the institutional trajectory of the OHR and its theoretical interpretation within broader debates on post-conflict international governance. The findings offer valuable insights for future peacebuilding missions in similarly complex environments.
