41. The truncated univariate rational moment problemRajkamal Nailwal, Aljaž Zalar, 2025, izvirni znanstveni članek Povzetek: Given a closed subset $K$ in ${\mathbb R}$, the rational $K$-truncated moment problem ($K$-RTMP) asks to characterize the existence of a positive Borel measure $\mu$, supported on $K$, such that a linear functional ${\mathcal L}$, defined on all rational functions of the form ${f \over q}$, where $q$ is a fixed polynomial with all real zeros of even order and $f$ is any real polynomial of degree at most $2k$, is an integration with respect to ▫$\mu$▫. The case of a compact set ▫$K$▫ was solved by Chandler in 1994, but there is no argument that ensures that $\mu$ vanishes on all real zeros of $q$. An obvious necessary condition for the solvability of the $K$-RTMP is that ${\mathcal L}$ is nonnegative on every $f$ satisfying $f|_K \ge 0$. If ${\mathcal L}$ is strictly positive on every $0 \ne f|_K \ge 0$, we add the missing argument in Chadler's solution and also bound the number of atoms in a minimal representing measure. We show by an example that nonnegativity of ${\mathcal L}$ is not sufficient and add the missing conditions to the solution. We also solve the $K$-RTMP for unbounded $K$ and derive the solutions to the strong truncated Hamburger moment problem and the truncated moment problem on the unit circle as special cases.

44. Pomlajevanje in ekološke lastnosti rdečega hrasta (Quercus rubra L.)Dušan Roženbergar, Jurij Diaci, Matteo Bottosso, Tim Pirc, Blaž Fricelj, Kristjan Jarni, Andrej Rozman, 2024, izvirni znanstveni članek Povzetek: V članku obravnavamo ekologijo, potencialno invazivnost, pomlajevanje, razširjenost in lastnosti rdečega hrasta (Quercus rubra L.) v Sloveniji. V čistem sestoju rdečega hrasta v Panovcu smo s pomočjo transektov (3 ploskve velikosti 4 × 4 m na transekt) v smeri proti sosednjim pretežno gradnovim sestojem analizirali drevesno sestavo in zastiranje mladja. Ugotovili smo, da se rdeči hrast v pasu do 50 m od matičnega sestoja dobro pomlajuje s povprečnimi gostotami okoli 40.000 osebkov na hektar. Zastiranje mladja rdečega hrasta je bilo na robu matičnega sestoja 79 % in se je v oddaljenosti 50 m zmanjšalo na 21 %, medtem ko je delež zastrtosti z mladjem gradna povečal s 4 % na robu sestoja na 39 % 50 m stran. Širjenje rdečega hrasta zunaj matičnih sestojev je razmeroma omejeno in ga je mogoče nadzorovati s pomočjo rednih gozdnogojitvenih ukrepov. Cilj na takih območjih so mešani sestoji, ki vključujejo rdeči hrast, ki hitro raste, je odporen na posledice podnebnih sprememb in ga je mogoče vzgojiti za pridelavo kakovostnega lesa.

45. Autumn phenology of mountain birch at the sub-arctic treeline in comparison with silver birch in the cold and mild temperate zonePaolo Zuccarini, Friederike Gehrmann, Manuela Balzarolo, Omar Flores, Jožica Gričar, Bertold Mariën, Matteo Campioli, 2025, izvirni znanstveni članek Povzetek: Lack of knowledge on autumn phenology of deciduous trees still exists for high-latitude regions. We studied the leaf and wood growth autumn phenology of mountain birch in a sub-arctic climate (northern Sweden) and compared them with the same dynamics for silver birch in a temperate climate (southern Norway and Belgium). The first autumn phenophase for mountain birch was the decline of the remotely sensed Terrestrial Chlorophyll Index (TCI) at the end of July. This was followed by wood growth cessation, onset of chlorophyll degradation and of loss of canopy greenness, and the latter accompanied by onset of anthocyanin production and flavonoids degradation. The earlier timing of TCI decline than chlorophyll degradation was probably due to the different scales of measurements (ecosystem level vs. tree leaves, respectively). In 2020, the decline in canopy greenness started in the same period at the three studied sites, showing an unexpected early timing for Belgium, likely due to the very warm late summer conditions and drought stress or intraseasonal legacy effects. Accordingly, wood growth cessation also occurred unexpectedly earlier in Belgium than in Norway. The end of senescence was inversely related to latitude. Our study presents, for the first time, the autumn timeline of a deciduous species at the northern treeline, and indicates that the timing of autumn phenology of birch populations does not consistently follow the latitudinal gradient but varies according to the phenophase, the scale of measurements and the current year meteorological conditions.

50. D1.4 Qualitative feedback from WINBLUE Labs : WINBLUE, empowering women and mainstreaming gender equality in the blue economyAna Rotter, Ernesta Grigalionyte-Bembič, 2024, elaborat, predštudija, študija Povzetek: The WINBLUE project takes a multi-actor, data-driven, trans-sectoral and practice-cantered approach to accelerate the empowerment of women in the blue economy. For this reason, the collection qualitative data has been performed. The data collection exercise analysed in this Deliverable, is essential to identify challenges faced by women working in the WINBLUE selected sectors and to provide a basis for establishing future recommendations. The main messages identified in the Deliverable are: 1. Understanding gender and gender equality. For many years, gender equality was considered only as the gender distribution of women and men employed in an organization. This has been changed only in recent years, especially by requesting the adoption of the Gender Equality Plans. 2. Gender Equality Plan (GEP). The EU encouraged the mandatory adoption of GEPs in public organisations if the organisation wants obtain EU funding. If it was not enforced by the EU, many legal entities would not introduce it. However, many organizations see this as a formal “tick the box” exercise without its formal implementation. Nevertheless, in blue economy, where a lot of workforce operates in private or non-governmental entities, GEPs can also be of high value to make structural and cultural changes in individual organizations. 3. Obstacles, such as stereotypes, traditions, mentality and prejudices are still very present in today's society and represent one of the biggest obstacles for women when entering or trying to move up in the sectors of the blue economy selected by WINBLUE (Blue circular bioeconomy and biotechnology, Fisheries and aquaculture, Sustainable coastal and marine tourism, Offshore renewable energy, Cutting-edge marine technologies and others, such as marine education, marine policy, port management, navigation). An important obstacle to mention is motherhood and balancing work and family life. This is not only related to maternity leave and at least one year's absence from work, but also to caring responsibilities and domestic duties, as well as ineffective institutional or national policies on work-life balance. In addition, women are subject to enormous social pressure with regard to role models, family and their life choices. 4. Education plays a very important role in raising awareness, fighting stereotypes, changing mindsets and raising new generations who will understand the meaning and importance of gender equality. It starts at an early age with the first lessons learned from parents and continues at school, university and vocational training. Hence, educational activities should be an integral part of any GEPs. 5. Recruitment and promotion. Gender alone should not be a factor in hiring and promotion. The decision to recruit or promote a person should be made on the basis of the candidate’s skills, abilities, competencies and experience. However, to address unconscious bias and ensure transparent recruitment and promotion procedures, clear guidelines with standardized questions and tasks should be established and records of the selection/promotion process should be kept so that the transparency of the process can be reviewed if necessary. Recruitment and promotion committees should be composed of both male and female employees. 6. Creation of support networks is mostly seen as a valuable tool that can provide mutual support, exchange of good practices and introduce ambassadors with good practice examples. 7. The WINBLUE project, in particular the qualitative and quantitative data collection, as well as the GEP models can make a decisive contribution to introducing changes in the blue economy sector, improving the representation of women in this sector and increasing their number in leadership positions. The WINBLUE project is a good starting point to raise awareness and increase the visibility of women in the blue economy sector. 8. Sustainability of the results of this project should already be considered at this point, during its implementation stage. This entails that through identified stakeholders, activities and GEPs proposed, the systematic quantitative and qualitative data analysis should be maintained and regular monitoring of GEP implementation should be established, including the collaboration with national and international legislative/funding organizations and other organizations from the blue economy sector.
