Introduction . Aphthous stomatitis is one of the most common inflammatory and ulcerative diseases of the oral mucosa in children. In school-age children with secondary immunodeficiency, aphthous lesions may demonstrate a prolonged, recurrent, and clinically severe course. Impairment of cellular and humoral immunity, reduced mucosal resistance, nutritional deficiencies, chronic infections, and systemic diseases contribute to persistent inflammation and delayed epithelial regeneration.To summarize the principal pathomorphological features of aphthous stomatitis developing in school-age children with secondary immunodeficiency. A narrative review of scientific literature concerning the pathogenesis, immunological mechanisms, and morphological characteristics of aphthous stomatitis was performed. Publications describing oral mucosal lesions in patients with acquired immune dysfunction, chronic infections, nutritional deficiencies, and other causes of secondary immunodeficiency were analyzed. Particular attention was paid to epithelial alterations, inflammatory-cell composition, microcirculatory disorders, stromal changes, and tissue regeneration.Aphthous stomatitis associated with secondary immunodeficiency is characterized by epithelial degeneration, focal necrosis, ulcer formation, fibrinous-necrotic exudation, inflammatory infiltration, vascular congestion, edema, and impaired reparative processes. The inflammatory infiltrate commonly contains lymphocytes, macrophages, neutrophils, and plasma cells. Immune dysregulation involving T lymphocytes and pro-inflammatory cytokines promotes epithelial injury and prolongs ulcer healing.Secondary immunodeficiency substantially modifies the morphological course of aphthous stomatitis in school-age children. The lesions demonstrate more pronounced epithelial destruction, persistent inflammatory infiltration, microcirculatory impairment, and delayed regeneration. Recognition of these features is important for differential diagnosis and the selection of combined immunological and local therapeutic approaches.

This record contains the Voices of Migration questionnaire, a psychographic, narrative-based research instrument designed to document the experiences, identity, perceived inclusion and future projections of adult migrants in intercultural and socio-educational contexts. The instrument comprises 19 substantive items organised into five dimensions — identity and origin; the emotional dimension of migration; the migratory process and initial adaptation; current perceived inclusion; and future projections and aspirations — of which eighteen are open-ended biographical prompts and one is a closed 1–5 Likert item. Unlike closed psychometric scales, the questionnaire foregrounds the situated, narrative texture of the migratory experience. The record includes the original version submitted to expert judgement, the content-validated revised version, and the full item-to-dimension mapping. Content validity was established through a mixed panel of academic and situated-knowledge experts (CVR/CVI indices and qualitative thematic analysis). These materials accompany the article "Content Validation of the Voices of Migration Questionnaire: Integrating situated knowledge into intercultural measurement". The instrument is released for use by researchers, socio-educational practitioners and third-sector organisations working with migrant populations.

Proof available to an agent must be carried by retained, inspectable physical records. A declared proof interface determines which alternatives those records must separate and thereby induces a lower-bound family R(n). If the agent has work budget B < ∞ and every irreversible retained distinction costs at least ε > 0, then any instance satisfying εR(n) > B lies beyond that interface. The Physical Counting Impossibility Theorem therefore rules out universal exact proof for every fixed-budget substrate whenever R(n) is unbounded. Landauer's principle supplies the ideal physical scale ε ≥ k_BTln 2 per irreversible bit, experimentally verified to ±10%. For separable audit interfaces, exact query complexity gives R(n) = D(fₙ): parity requires n retained local distinctions, while a hidden n-bit truth table requires 2ⁿ. Global observables, compressed audits, interactive protocols, quantum witnesses, and finite survey catalogs define different evidence objects and therefore different families R(n). A reversible device may produce an answer and erase its scratch history; proof additionally requires the records licensed by the declared interface. Finite causal access supplies an independent bound on record acquisition.

The key condition for utilizing fly ash for mercury adsorption from flue gas is the affinity of mercury to the ashsurface under electrostatic precipitator (ESP) conditions. Experimental results suggest that mercury adsorptiononto ash with very low unburned carbon content involves significant chemisorption contributions, as evidencedby strong Hg retention in sequential leaching tests (HCl-resistant) and thermal desorption profiles (release >600◦C). Nevertheless, the presence of unburned carbon enhances mercury retention capacity and environmentalstability once captured. Mercury binds strongly to adsorption sites on the ash surface, forming highly stable andirreversible complexes. Sorption kinetics primarily control the mercury adsorption process, influenced by temperature,mercury concentration, and the concentration of metal oxides on the ash surface. Tests show thatmercury adsorbed on fly ash has minimal environmental leaching risk. Mercury is not extractable from ash bywater, and only a small amount (approximately 10%) dissolves in mildly acidic conditions (1 M HCl). Totalmercury extraction is achievable exclusively with aqua regia, indicating that mercury predominantly exists inmetallic form or as highly stable complexes bonded strongly to the ash surface. Mercury concentration on ashcorrelates positively with increased unburned carbon content, whereas larger ash particle sizes correlate negativelywith mercury adsorption efficiency. The experiments confirm that ESP conditions can be optimised tosignificantly increase mercury capture efficiency, potentially removing up to 65% of mercury initially present incoal. These findings underline the crucial role of ESP operational parameters and ash composition in maximizingmercury removal from flue gas and reducing environmental contamination risks.

Deliverable 3 (M22) and supporting material of the CLIMAAX–CRETE project "Climate Resilient crETE", implemented by the Region of Crete with the Technical University of Crete under the CLIMAAX Horizon Europe programme (Grant Agreement No. 101093864). Phase 3 translates the climate risk assessment of Phases 1–2 into an operational drought-monitoring pathway for the Region of Crete: a basin-group drought severity index derived from the Copernicus Combined Drought Indicator, calibrated against basin-specific percentile thresholds and validated over the 2012–2025 record; the linkage of that index to the four drought-status levels of the Action Plan for Combating Drought and Water Scarcity; a screened two-track measures framework separating operational response from strategic adaptation; the Drought Response Matrix; and a staged roadmap to operational deployment. The accompanying archive contains the underlying datasets (dekadal severity index for the nine basin groups 2012–2025, catalogue of 113 drought events, Copernicus EDO indicator series aggregated to basin group), the operational instruments (Drought Response Matrix, measures screening workbooks in English and Greek with accompanying guidelines, basin-group shapefile), and the record of communication and dissemination outputs.

This replication package contains the code, data, and instructions needed to replicate the experiments described in the paper "How Developers Experience Debugging Unfamiliar Codebases with Code Tours Generated and Evaluated by Local LLMs". Context. Code tours are interactive, onboarding documentation that guide developers through a codebase. Large Language Models (LLMs) can automatically synthesize code tours. Prior work on code tour generation has not examined developer experience or trust calibration when debugging unfamiliar codebases with code tours generated and evaluated by open-weight LLMs.Objectives. This study surveys how the properties of components in open-weight LLM-authored code tours influence developers' experiences when debugging unfamiliar codebases.Method. We built a pipeline that generated and evaluated code tours from real reproducible bugs. Twenty-six developers with varying backgrounds participated in a user study. In total, 26 code tours were authored from real Java bugs mined from 2025 GitHub commits, with each tour independently judged by two different LLMs, resulting in 52 evaluated configurations. Participants thought aloud as they explored each tour. Three authors qualitatively coded the interviews to identify recurring themes.Results. Developers generally preferred tours that scaled detail with the code length, avoided merely restating code, were easily scannable, and adopted a guiding tone. However, some preferences were mutually exclusive, such as the use of imperative mood. Stack traces were often insufficient to identify all steps developers found relevant. Developers also trusted descriptions they perceived as human-written more than those they believed were AI-generated. Finally, LLM-generated annotations of tour quality were unreliable: sycophancy, confabulation, and incoherence were pervasive.Conclusion. This work lays a basis for future research on fine-tuning open-weight models for code tour generation, personalizing generation to accommodate diverging preferences, selecting relevant steps beyond stack traces, calibrating users' trust to avoid both disuse and misuse, and improving open-weight LLMs' ability to be more trustworthy evaluators

This dataset presents analytical data for four different sections, likely from sample measurements. It includes parameters such as specific surface area, concentration, surface properties, particle diameter (dp), and contents of elements including TOC, mercury (Hg), copper (Cu), and manganese (Mn). The data shows a declining trend for specific surface area, surface properties, TOC, and manganese from the first to the fourth section. Mercury and copper concentrations exhibit more variable behavior, with copper reaching its maximum in the fourth section. These measurements serve to provide detailed characterization of the composition and material properties across individual sections.
