653. The impact of sanitary felling during large-scale disturbances on regulating ecosystem services in norway spruce-dominated Pre-Alpine beech forests of SloveniaAnže Martin Pintar, Andreja Ferreira, Pia Höfferle, Anže Japelj, 2025, izvirni znanstveni članek Povzetek: Ecosystem services (ES) are closely linked to nature-based solutions, which can mitigate the negative impacts of climate change or provide society with direct tangible and intangible benefits. In the context of a changing climate, it is essential to preserve these services despite increasing disturbances. In this study, we analysed changes in the structure and composition of the Jelovica forest complex (NW Slovenia) over the past two decades and assessed the provision of key regulating forest ES—specifically, soil erosion control, regulation of surface and groundwater flows, and regional climate regulation. The area has historically seen the artificial promotion of Norway spruce and, in recent decades, has been increasingly affected by large-scale disturbances and bark beetle outbreaks. We examined how these climate-related disturbances have influenced the availability of regulating ES. Over the past twenty years, the share of spruce in the growing stock in the Jelovica area decreased from 67% to 62%. We compared structural and compositional changes between two periods, 2001–2009 and 2015–2023, based on available forest management data. In both periods, mature stands were the dominant developmental stage. In the northwestern part of the Jelovica plateau, where extensive sanitary felling was carried out, the proportion of sapling stands increased significantly—unlike in other parts of the plateau. Areas affected by extensive sanitary felling exhibited statistically significantly lower evapotranspiration and reduced soil erosion control capacity, as well as higher levels of groundwater recharge, compared to other areas.

654. Symmetric nonnegative trifactorization of pattern matricesDamjana Kokol-Bukovšek, Helena Šmigoc, 2025, izvirni znanstveni članek Povzetek: A factorization of an $n \times n$ nonnegative symmetric matrix $A$ of the form $BCB^T$, where $C$ is a $k \times k$ symmetric matrix, and both $B$ and $C$ are required to be nonnegative, is called the Symmetric Nonnegative Matrix Trifactorization (SN-Trifactorization). The SNT-rank of $A$ is the minimal $k$ for which such factorization exists. The SNT-rank of a simple graph $G$ that allows loops is defined to be the minimal possible SNT-rank of all symmetric nonnegative matrices whose zero-nonzero pattern is prescribed by the graph $G$. We define set-join covers of graphs, and show that finding the SNT-rank of $G$ is equivalent to finding the minimal order of a set-join cover of $G$. Using this insight we develop basic properties of the SNT-rank for graphs and compute it for trees and cycles without loops. We show the equivalence between the SNT-rank for complete graphs and the Katona problem, and discuss uniqueness of patterns of matrices in the factorization.

655. Country report - Slovenia : Deliverable D5.4 1 country reportSandra Končan, Mateja Sedmak, Zorana Medarić, Ksenija Perković, Barbara Gornik, 2025, končno poročilo o rezultatih raziskav Povzetek: The objective of WP3 was to design a programme of activities tailored to each local context and the needs of 30 migrant women participants and to implement the programme during a six-month period to conclude which practices have a potential of sustainability and can contribute to migrant women’s integration. The developed Activity Cluster programme consists of three clusters: Upskilling, Awareness-raising, and Social. In each cluster, several sub-activities were designed, covering various topics related to work, education, awareness of rights and duties and social interaction in the local environment. After the implementation of the programme, it was concluded which activities were the most successful and what could be adapted to improve local integration of migrant women.

656. $F$-birestriction monoids in enriched signatureGanna Kudryavtseva, Ajda Lemut Furlani, 2025, izvirni znanstveni članek Povzetek: Motivated by recent interest to $F$-inverse monoids, on the one hand, and to restriction and birestriction monoids, on the other hand, we initiate the study of $F$-birestriction monoids as algebraic structures in the enriched signature $(\cdot, \, ^*, \,^+, \, ^\mathfrak{m},1)$ where the unary operation $(\cdot)^\mathfrak{m}$ maps each element to the maximum element of its $\sigma$-class. We find a presentation of the free $F$-birestriction monoid ${\mathsf{FFBR}}(X)$ as a birestriction monoid ${\mathcal F}$ over the extended set of generators $X\cup\overline{X^+}$ where $\overline{X^+}$ is a set in a bijection with the free semigroup $X^+$ and encodes the maximum elements of (non-projection) $\sigma$-classes. This enables us to show that ${\mathsf{FFBR}}(X)$ decomposes as the partial action product $E({\mathcal I})\rtimes X^*$ of the idempotent semilattice of the universal inverse monoid ${\mathcal I}$ of ${\mathcal F}$ partially acted upon by the free monoid $X^*$. Invoking Schützenberger graphs, we prove that the word problem for ${\mathsf{FFBR}}(X)$ and its strong and perfect analogues is decidable. Furthermore, we show that ${\mathsf{FFBR}}(X)$ does not admit a geometric model based on a quotient of the Margolis-Meakin expansion $M({\mathsf{FG}}(X), X\cup \overline{X^+})$ over the free group ${\mathsf{FG}}(X)$, but the free perfect $X$-generated $F$-birestriction monoid admits such a model.

659. Synthesis of a water-soluble BODIPY for targeting and assessing the function of endoplasmic reticulumJacopo Tricomi, Giacomo Biagiotti, Tommy Chastel, Serena Filiberti, Hana Kokot, Francesca Mancusi, Maja Žežlina, Layal Rajeh, Iztok Urbančič, Stéphane Bodin, 2025, izvirni znanstveni članek Povzetek: We report here on a straightforward methodology to synthesize a new water-soluble fluorescent probe TrisBODIPY-OH 1 that contains three pH-independent hydrophilic arms. This probe has been prepared by exploiting a synthetic strategy that includes as a key step the combination of a Cu(I)-catalyzed azide−alkyne cycloaddition (CuAAC) and a Sonogashira cross-coupling in a sequential one-pot approach. Tris-BODIPY-OH 1 provides a significant advancement in the field by expanding the BODIPY toolbox with a biocompatible water-soluble probe, which can be used to specifically label and assess the function of the endoplasmic reticulum.

660. ICARUS : development, optimization, and harmonization of innovative characterization techniques for large volumes of radioactive wasteBas Janssen, José Luis Leganés Nieto, Yevheniia Kudriashova, Lixin Qiao, Ferdinando Giordano, An Bielen, Marko Štrok, Anumaija Leskinen, Arturas Plukis, Eros Mossini, 2025, izvirni znanstveni članek Povzetek: In the framework of the EURAD-2 partnership, the ICARUS (Innovative ChARacterization techniques for large volUmeS) work package aims at further developing, optimizing and harmonizing innovative techniques for the radiological, physical and chemical characterization of large volume of low/intermediate-level mixed waste, as it could be critical for the safe implementation of radioactive waste management programmes of the member states. Destructive Techniques (DT), Non-Destructive Techniques (NDT), and Scaling Factors (SF) will be investigated. Four use cases will be considered according to the end users’ needs: (i) enabling fast and sufficiently accurate characterization of gamma activity distribution by NDT in complex large packages, including mixed wastes as heterogeneous legacy waste; (ii) improving and simplifying NDT for determining physico-chemical properties; (iii) improving sensitivity, accuracy, and uncertainty and replacing the expensive and time-consuming radiochemical analysis of long-lived Difficult To Measure (DTM) radionuclides by DT; (iv) improving accuracy, uncertainty, and reliability of the SF approach to estimate DTM radionuclides in raw mixed waste. Specific education and training materials and opportunities will be provided to foster career advancement of young professionals and researchers. The research activities will be carried out by 29 organizations from 17 countries.
