Item type: Pozycja , Probing gluon GTMDs of the proton in deep inelastic diffractive dijet production at HERA(American Physical Society, 2024-09-20) Linek, Barbara; Łuszczak, Marta; Schäfer, Wolfgang; Szczurek, AntoniWe calculate several differential distributions for diffractive dijets production in ep→e′jet jet p in the perturbative QCD dipole approach using off diagonal unintegrated gluon distributions (generalized transverse momentum dependent distributions, GTMDs). Different models from the literature are used. We concentrate on the contribution from exclusive qqbar dijets. Results of our calculations are compared to H1 and ZEUS data, including specific experimental cuts in our calculations. In general, except for one GTMD, our results are below the HERA data. The considered mechanism is expected to gives a sizeable contribution to the ZEUS data, while it is negligible in the kinematics of the H1 measurement. This is in contrast to recent results from the literature where the normalization was adjusted to some selected distributions of the H1 collaboration and no agreement with other observables was checked. The ZEUS data provide stricter limitations on the GTMDs than the H1 data. We conclude, based on comparison to different observables, that the calculated cross sections are only a small fraction of the measured ones which contain probably also processes with pomeron remnant. Alternatively one could try to explain the experimental data by inclusion of qqbarg component of the photon wave function. We present also azimuthal correlations between the sum and the difference of dijet transverse momenta. The cuts on transverse momenta of jets generate corresponding azimuthal correlations that can be misidentified as due to elliptic gluon distributions.Item type: Pozycja , Probing GPDs in Exclusive Electroproduction of Dijets Data(American Physical Society, 2026-06-08) Chall, Trambak Jyoti; Łuszczak, Marta; Schäfer, Wolfgang; Szczurek, AntoniWe summarize the formalism for calculating the exclusive dijet production in 𝑒𝑝 →𝑒′𝑗𝑗𝑝 in collinear QCD factorization, using generalized parton distributions as the soft hadronic input modeled in the double distribution approach. We include all leading-order contributions coming from light sea and valence quark exchanges, and gluon exchanges for both light quark-antiquark production and also the heavy 𝑐 \bar𝑐 final state. We present results for several differential distributions for the cross section evaluated over a broad region of phase space, covering a wide range of inelasticity and photon virtuality. The gluon and sea contributions exhibit similar shapes, whereas the valence contribution, though relatively small, shows a markedly different behavior. The latter becomes particularly noticeable at large 𝑥ℙ, a kinematic region not explored at HERA, but potentially accessible in future measurements at the Electron Ion Collider. This requires further feasibility studies. We also present the azimuthal angle modulation between the leptonic and the outgoing dijet planes for the general case, as well as for the ZEUS kinematic region where we see reasonable agreement with the data for diffractive deep inelastic scattering parameter 𝛽 ≳0.4.Item type: Pozycja , Complete database of the oak regeneration census performed in 2022-2024 in abandoned agricultural land(2026-08) Bobiec, AndrzejComplete database of the oak regeneration census performed in 2022-2024 in abandoned agricultural land contains Excel spreadsheet including the cross-checked database of all records (oak seedlings/saplings) with their geographic coordinates. Besides basic biometric parameters (height, diameter of the root collar, diameter at breast hight, sread of crown), the table includes other qualitative traits. There is the box frame in the sheet with variables' definitions (in Polish) - sheet "DbRegAll-NCN". The second sheet "Delta-H" collects the data referring to the saplings' vertical growth rate.Item type: Pozycja , Appearance Comparison Is the Strongest Independent Correlate of Eating Disorder Risk among Adolescents(MDPI, 2026-08-03) Polak-Szczybyło, EwelinaBackground: Previous studies have demonstrated associations between social media use, body image, and the risk of eating disorders. However, it remains unclear whether these associations are attributable to social media use itself or to processes related to how users perceive and respond to the content encountered on these platforms. Methods: This cross-sectional study included 750 secondary school students aged 17–18 years. Participants completed an author-developed questionnaire assessing social media use, the perceived influence of social media content on body image, and com-parisons of their own body shape with those presented on social media, as well as the Eating Attitudes Test (EAT-26). Results: TikTok was the most frequently used social media platform. An elevated risk of eating disorders (EAT-26 ≥ 20) was identified in 9.7% of participants. Greater perceived influence of social media content on body im-age and more frequent body shape comparisons were independently associated with higher EAT-26 scores and a greater likelihood of scoring ≥20 on the EAT-26. Conclu-sions: Body image-related processes, particularly comparisons of one’s own body shape with those presented on social media, may be more relevant to eating disorder risk than the amount of time spent using social media itself. These findings highlight the importance of preventive interventions focused on media literacy and reducing maladaptive appearance comparisons.Item type: Pozycja , GIS data related to the study of the grass fire effect on oak regeneration(2026-08) Bobiec, AndrzejGIS data related to the study of the grass fire effect on oak regeneration with map
