This study aimed to provide a more in-depth analysis of the fruit quality of three table grape varieties: 'Moldova', 'Lasta', and 'Italia', cultivated in the Žepče area (Bosnia and Herzegovina). The findings from the comparative analysis indicated substantial variations in grape quality among the studied varieties. 'Moldova' grapes exhibited significantly higher total soluble solids and pH values than those of the other table grape varieties. 'Moldova' also had higher total phenolic and flavonoid contents in the grape skin relative to 'Italia' and 'Lasta'. On the other hand, 'Italia' variety showed the highest titratable acidity, followed by 'Lasta' and 'Moldova'. Total phenolic and flavonoid contents were highly positively correlated with the antioxidant capacities of all analyzed grape samples, suggesting that phenolic compounds contribute significantly to the antioxidant properties of grapes. Study results also indicated that all heavy metal levels tested in grapes were below the threshold limits, which was expected considering that the experimental soil was not contaminated with the heavy metals being assessed. Overall, the results from the study have shown that all grape varieties studied hereby displayed a satisfactory level of quality based on key chemical parameters, and that the experimental area is quite favorable for their cultivation.

The semiconductor industry is foundational to modern technology, yet its complex global multi-relational firm network remains poorly understood, posing challenges to scientists, firms, and policymakers. Traditional analysis relies on proprietary databases that are often expensive, incomplete, and slowly updated, limiting their ability to capture rapidly evolving dependencies. Here, we demonstrate that a novel, generalizable methodology combining Large Language Models (LLMs) with open web data can reconstruct this network and its structural dynamics at scale. We identify and classify supply-chain, partnership, and ownership links from 170 million semiconductor firm webpages, yielding a temporal network of over 1,300 linked firms. We validate link-extraction quality (Precision: 0.884; F1-score: 0.784), network overlap and complementarity with a proprietary database, and consistency with aggregate economic data. Our network reveals a temporary 9% decline in edges during the 2022 chip shortage, rapid increases in the centrality of AI supply-chain bottleneck firms such as NVIDIA, and geographic realignment of interfirm relations amid geopolitical turbulence. This generalizable framework overcomes barriers to transparency and provides essential, up-to-date maps for assessing resilience and informing policy across strategically relevant sectors.

In this paper, we study a discrete-time host–parasitoid model in which the host survival probability is governed by a general escape function that satisfies natural biological constraints. The host population follows a Beverton–Holt growth model, while a constant number of individuals remains in a refuge each generation. Both host availability and current parasitoid density influence parasitoid population dynamics. We show that the system admits three possible equilibrium outcomes: no equilibrium, a parasitoid-free equilibrium, or a unique interior equilibrium where both species coexist. Conditions are established under which the parasitoid-free equilibrium is globally asymptotically stable. In certain parameter ranges, we prove the occurrence of transcritical bifurcation at the boundary equilibrium and Neimark–Sacker bifurcation at the interior equilibrium. Despite the possibility of complex behavior, we prove that, within specific parameter ranges, the system is uniformly persistent and permanent, ensuring the long-term survival of both populations. Numerical simulations are included to support and illustrate the theoretical results.

The dark web hosts a dynamic ecosystem of cybercrime forums and marketplaces that adapt to law enforcement pressure, technological change, and economic incentives. Prior research has extracted cyber threat intelligence from these platforms using static snapshots, with limited attention to how discussions evolve over time. In this study, we conduct a longitudinal analysis of 25,065 websites in the dark web using 11,403,638 HTML snapshots (approximately 1245.38 GB) collected over six years. We develop a longitudinal topic-modeling framework combining domain-specific embeddings, density-based clustering and temporal aggregation to measure topic prevalence and lifecycle at the website level. Our analysis identifies 55 thematic clusters. We find that approximately 75% of total discussion volume is concentrated in a small set of persistent core topics, while short-lived themes account for approximately 3% of activity. The median topic lifespan is 75 months, indicating gradual thematic evolution rather than abrupt replacement.

We develop a framework in which Yukawa hierarchies arise from powers of fully anarchic spurions transforming in higher representations of the flavor symmetry group $SU(2)^{n_2}\times SU(3)^{n_3}$. The core mechanism is the progressive lifting of Yukawa ranks through successive outer products of composite doublets and triplets. We formulate the general construction in detail and build explicit models realizing it. We then investigate whether renormalizable scalar potentials for higher $SU(2)$ representations can dynamically generate anarchic spurions with non-vanishing composites. The framework predicts distinctive patterns in flavor-changing neutral currents and potentially observable stochastic gravitational-wave backgrounds.

Primary hypothermia arises from prolonged exposure to low environmental temperatures without underlying pathology, whereas secondary hypothermia is triggered by impaired thermoregulation due to factors such as disease, trauma, or substance use. This study aimed to investigate core temperature changes in rats exposed to specific water temperatures over time, with a focus on differentiating primary and secondary hypothermia induced by alcohol and benzodiazepines.Survival analysis was performed using Kaplan–Meier survival curves to compare the time to event (in minutes) among three experimental groups: Control, ethanol, and Diazepam. Core temperatures were recorded at five key points: baseline (normal temperature), post-ketamine anesthesia, during immersion, at hypothermia onset, and at the time of death. Survival times were also recorded and statistically analyzed. Median survival times were highest in the control group (35 minutes), followed by Diazepam (29 minutes) and ethanol (28 minutes). Pairwise comparisons using the log-rank test, adjusted for multiple comparisons via the Benjamini-Hochberg method, revealed a statistically significant difference between the control and diazepam groups (p = 0.018), with the control group demonstrating longer survival time. A significant interaction between Diazepam and time was observed (β = -0.23, 95% CI: -0.35 to -0.12, p < 0.001), indicating that the rate of temperature decline over time was significantly greater in the Diazepam group compared to the control group. Our results indicate that Diazepam accelerates the decrease in body temperature over time, which may contribute to its observed effect on survival, and that Diazepam administration is associated with a significant reduction in survival time compared with untreated controls. Ethanol did not significantly alter the measured thermoregulatory or survival outcomes in this pilot study. Any potential forensic relevance of ethanol-induced hypothermia remains speculative and requires further investigation in larger, adequately powered studies. Our results could have potential forensic implications in differentiating between primary and drug-induced as secondary hypothermia in medico-legal investigations.

Global reporting of obesity is commonly based on comparisons over multiple decades1 and lacks a granular and systematic analysis of its dynamics. We used 4,050 population-based studies with measured height and weight data on 232 million participants to assess the worldwide dynamics of obesity from 1980 to 2024. The rise in obesity decelerated in school-aged children and adolescents throughout the 1990s in many high-income countries, and subsequently plateaued in most at age-standardized prevalences spanning 20 percentage points, from 3–4% for girls in Japan, Denmark and France to 23% for boys in the USA. There were indications of a small decline in obesity in children and adolescents in some high-income western countries (for example, Italy, Portugal and France) since the 2000s. Similar trends were seen in some countries in Central and Eastern Europe. In adults, the rise in obesity slowed down in high-income western countries about a decade after children, followed by a plateau or possibly a small reversal of the rise in some countries (for example, Spain). In most low-income and middle-income countries, the annual absolute change in prevalence has remained stable or increased over time, even though prevalence has surpassed that of high-income countries. These highly varied dynamics suggest that the social, economic and technological trends that influence the availability, affordability and use of different foods may have helped control the rise in obesity in high-income countries, but require policy interventions in low-income and middle-income countries.

Background and purpose: Ants are a dominant terrestrial insect group and rank among the most abundant and diverse animals on land, playing significant ecological and economic roles. Due to their global diversity and the high morphological similarity among closely related species, accurate identification of ants can be difficult. The aim of this study was to assess the species status within one of the most important ant groups – Lasius genus, subgenus Lasius s. str. – in Bosnia and Herzegovina, using a combination of morphological and molecular approaches. Materials and methods: Forty-two individuals were collected from four localities and identified using appropriate morphological keys. DNA barcoding was performed to complement morphological identification, and sequences were deposited in GenBank. A Maximum Likelihood phylogenetic tree was constructed using MEGA11, incorporating both the sequences from this study and selected sequences from the BOLD database. Results: We identified three species - Lasius niger, L. platythorax and L. emarginatus, by applying both approaches. Specific dark-brown mesosoma and a new haplotype were recorded for L. emarginatus. Conclusions: The observed morphometric differences and a discovery of a new Lasius emarginatus haplotype suggest that the diversity of species within the subgenus in Bosnia and Herzegovina is greater than previously recognized. Further research is warranted to explore the regional diversity and ecological roles of Lasius species.

Functional dyspepsia (FD) is a common disorder of gut–brain interaction in which psychological factors may influence symptom presentation. This cross-sectional study examined the associations between stress resilience, somatization, subjective well-being (SWB), and FD symptoms, with a particular focus on gender differences. Adult patients (≥ 18 years) presenting with dyspeptic symptoms and referred for their first upper gastrointestinal endoscopy were recruited at the University Clinical Hospital of Mostar, Bosnia and Herzegovina. Psychological factors were assessed using validated questionnaires, and FD symptom characteristics included FD subtypes, intensity, frequency, and duration. Group differences were analysed using appropriate parametric or non-parametric tests, whereas multinomial logistic regression and multivariate multiple regression were used to evaluate associations between psychological variables and FD outcomes. Lower resilience and SWB, along with a higher somatization, were significantly associated with membership to the mixed FD type. Higher somatization was associated with more severe symptoms, and higher age was associated with longer symptom duration. Higher SWB scores corresponded, although marginally, to less frequent symptom reporting. Several variables differed by sex/gender. These findings support the role of gut–brain interactions in FD and may inform the development of targeted psychological interventions.

This article examines how post-war Bosnian cinema mediates the unresolved absences of the Bosnian War through its cinematic portrayals of widowhood, mourning, and survival. Drawing on multi-sited ethnographic fieldwork among Bosnian war widows and a close reading of three films— Halima’s Path (dir. Arsen Anton Ostojić, 2012), Snow (dir. Aida Begić, 2008), and Days and Hours (dir. Pjer Žalica, 2004)—the article explores how film operates simultaneously as a repository of cultural memory and as an ethnographic lens into the lived afterlives of genocide. I argue that cinematic narratives of absence and endurance offer a counterpoint to the dehumanizing tendencies of nationalist historiography and the quantification of loss, instead foregrounding the intimate textures of grief, resilience, and feminine agency. By weaving ethnographic observation with film analysis, the study illuminates how post-war cinematography assumes a feminist political role—making visible the everyday struggles of women on the social margins and reframing their experiences as central to collective remembrance. Ultimately, I contend that film and ethnography together reveal how the missing persist not as voids but as vital presences, intricately woven into the moral, emotional, and cultural fabric of post-genocide Bosnia.

Background: Negative public attitudes promote undesirable stereotypes and stigma in stutterers. Method: To mitigate negative attitudes, 403 respondents combined from 16 international samples filled out the Public Opinion Survey of Human Attributes–Stuttering (POSHA–S) before and after interventions to improve attitudes and were compared to 249 respondents from seven control groups. Investigators aimed (a) to replicate an extreme case of regression to the mean (i.e., “crossover” effect) reported earlier in larger combined samples in which respondents with high pre-scores ended with low post-scores, respondents with low pre-scores finished with high post-scores, and intermediate scorers were unchanged; and (b) to identify individual POSHA–S items related to overall attitude change and among the high and low scorers. Results: As in previous studies, stuttering attitudes improved in the intervention group but not in the control group. Intervention and control respondents demonstrated “crossover” but less than the earlier samples due to lower pre–post correlations. Item contributions to pre–post change and differences among the three change groups were inconsistent; however, high agreement items by respondents were less likely to vary than low agreement items. Conclusion: The “crossover” effect was replicated, and future research should explore its presence in other measures or conditions.

Climate change significantly affects human physiology and contributes to increased morbidity and mortality, with heat stress representing one of the most severe consequences of thermal imbalance. The aim of this study was to analyze morphological changes to leukocytes on the peripheral blood smears of Wistar rats exposed to hyperthermia using the geometric morphometrics method. A total of forty Wistar albino rats were divided into three experimental groups according to water temperature exposure (37 °C, 41 °C, and 44 °C). Peripheral blood smears were prepared, stained, and digitally recorded using Motic Images Plus 2.0 software, after which selected images were analyzed using geometric morphometric programs (tpsDig, tpsUtil, and MorphoJ) to evaluate leukocyte shape variations. Comparative analysis demonstrated statistically significant morphological changes in polymorphonuclear cell shapes between the control group (37 °C) and rats exposed to 41 °C (p = 0.009). Significant differences were also identified in mononuclear cell morphology between the antemortem and postmortem groups (p = 0.00307). The findings indicate that exposure to elevated temperatures induces measurable alterations in white blood cell morphology, confirming that hyperthermia produces significant structural changes in polymorphonuclear cells and mononuclear cells detectable through geometric morphometric analysis.
