    Multispektrale Aufnahmen von Papyrusfragmenten zum Zweck der Tintenanalyse
    (Universität Leipzig, 2023-03-29) Walter, Vincent
    In dieser Sammlung befinden sich zu jedem Fragment, das im Rahmen des DFG-Projekts "Die Erschließung und Digitalisierung koptischer Papyri (sog. K-Tafeln) im Bestand der Papyrus- und Ostrakasammlung der Universitätsbibliothek Leipzig" katalogisiert und inventarisiert wurde, ein Ordner mit Bildern einzelner Buchstaben. Diese Bilder wurden mit einem Mikroskop vom Typ Dino-Lite AD4113T-I2V angefertigt. Für jeden Buchstaben gibt es drei verschiedene Bilder, die sich hinsichtlich ihrer Beleuchtung unterscheiden. Sie wurden unter den folgenden Lichtspektren aufgenommen: 1) sichtbares Licht, 2) UV-Licht (400 nm), 3) Nahinfrarotlicht (940nm). Vergleicht man die Wiedergabe der Tinte in den Aufnahmen unter sichtbarem und unter Nahinfrarotlicht, lässt sich grob der Tintentyp bestimmen. Bei Pflanzentinten ist die Tinte unter Nahinfrarotlicht gar nicht mehr zu sehen, bei Eisengallustinten verblasst die Tinte unter Nahinfrarotlicht, bei Rußtuschen ist keine Änderung der Opazität zu beobachten. Üblicherweise enthält jeder Ordner 18 Dateien mit Aufnahmen von 6 verschiedenen Buchstaben, in Einzelfällen kann die Zahl der Aufnahmen jedoch noch nach unten (bei besonders kleinen Fragmenten) oder nach oben (bei später aus Einzelfragmenten zusammengesetzten Joins) abweichen. Bei den Inventarnummern 4264–4266 gibt es jeweils mehrere Ordner, da hier zusammengehörige, aber separat verglaste Fragmente jeweils unter einer einzigen Inventarnummer katalogisiert wurden. Aus technischen Gründen sind die Aufnahmen gebündelt in Gruppen von etwa 50 Fragmenten hochgeladen. Metadaten und häufig auch frei zugängliche Bilder der jeweiligen Fragmente sind im Papyrusportal zu finden (https://www.papyrusportal.de/).

    DeepExtremeCubes
    (Universität Leipzig, 2024-12-19) Ji, Chaonan; Fincke, Tonio; Benson, Vitus; Camps-Valls, Gustau; Fernández-Torres, Miguel-Ángel; Gans, Fabian; Kraemer, Guido; Martinuzzi, Francesco; Montero, David; Mora, Karin; Pellicer-Valero, Oscar; Robin, Claire; Söchting, Maximilian; Weynants, Melanie; Mahecha, Miguel
    With climate extremes' rising frequency and intensity, robust analytical tools are crucial to predict their impacts on terrestrial ecosystems. Machine learning techniques show promise but require well-structured, high-quality, and curated analysis-ready datasets. Earth observation datasets comprehensively monitor ecosystem dynamics and responses to climatic extremes, yet the data complexity can challenge the effectiveness of machine learning models. Despite recent progress in deep learning to ecosystem monitoring, there is a need for datasets specifically designed to analyse compound heatwave and drought extreme impact. Here, we introduce the DeepExtremeCubes database, tailored to map around these extremes, focusing on persistent natural vegetation. It comprises over 40,000 globally sampled small data cubes (i.e. minicubes), with a spatial coverage of 2.5 by 2.5 km. Each minicube includes (i) Sentinel-2 L2A images, (ii) ERA5-Land variables and generated extreme event cube covering 2016 to 2022, and (iii) ancillary land cover and topography maps. The paper aims to (1) streamline data accessibility, structuring, pre-processing, and enhance scientific reproducibility, and (2) facilitate biosphere dynamics forecasting in response to compound extremes.

    Dataset Validation Study ILEA-Basis-T
    (Universität Leipzig, 2025-03-05) Liebers, Katrin; Siegemund-Johannsen, Steffen; Viernickel, Susanne; Redersborg, Helke; von Seeler, Isabelle; Richter, Virginia; Hartke, Sara; Kauffert, Matteo
    The validation study was conducted to statistically test the validity of the developed DBS. Accordingly, the materials that had been developed for the DBS over the course of the project and had already been tested were used. The parents of all participating children gave their consent. The research ethical standards were adhered to. Likewise, a positive vote of the ethics committee of the University of Leipzig was available. At the same time, further domain-specific test procedures were used to determine convergent and discriminant validity in the areas of early literacy and early mathematics (e.g. MBK 0, Krajewski, 2018; GISC-EL, Koch, Euker & Kuhl, 2016). In addition, a comprehensive rating-based evaluation form was developed for the Early Mathematics Observation Form, with a focus on suitability for everyday use and acceptance in practice. The observation procedures for well-being and the children's questionnaire on well-being were used by project staff, students, and preschool teachers. Convergent discrimination for the habitual well-being rating procedure was determined using a selection of parallel assessment methods (excerpts from KOMPIK; Mayr, Bauer, Krause, Kruse, & Schnirch, 2014; Leiden Inventory for the Child's Wellbeing in Day Care/LICW-D; De Schipper, Van IJzendoorn, & Tavecchio, 2004).

    BiSID-5k: A Bimodal Image Dataset for Seed Classification from the Visible and Near-Infrared Spectrum
    (Universität Leipzig, 2025-04-10) Kukushkin, Maksim; Bogdan, Martin; Goertz, Simon; Callsen, Jan-Ole; Oldenburg, Eric; Enders, Matthias; Schmid, Thomas
    The success of deep learning in image classification has been largely underpinned by large-scale datasets, such as ImageNet, which have significantly advanced multi-class classification for RGB and grayscale images. However, datasets that capture spectral information beyond the visible spectrum remain scarce, despite their high potential, especially in agriculture, medicine, and remote sensing. To address this gap in the agricultural domain, we present BiSID-5k, a thoroughly curated bimodal seed image dataset comprising paired RGB and hyperspectral images for 10 plant species, making it one of the largest bimodal seed datasets available. We describe the methodology for data collection and preprocessing and benchmark several deep learning models on the dataset to evaluate their multi-class classification performance. By contributing a high-quality dataset, BiSID-5k offers a valuable resource for studying spectral, spatial, and morphological properties of seeds, opening new avenues for research and applications.

    Supplementary data for: Weighted Shapley values and allocation of portfolio risk: One approach to solve the low-risk puzzle?
    (Universität Leipzig, 2025-11-05) Hiller, Tobias
    The data set contains data for the article “Weighted Shapley values and allocation of portfolio risk: One approach to solve the low-risk puzzle?”. This includes a description of the simulation settings, the Excel macros for calculating the results in the case of equal shares and random asset shares, and the 100,000 simulation results for both cases in Excel. Abstract of the paper: In this article, we extend the application of cooperative game theory to solve the so-called low-risk puzzle. Specifically, we apply concepts that consider asset weights in the allocation of portfolio risk. These weights can take into account various asset characteristics (e.g., image, popularity of an asset, corporate social responsibility, innovative strength) that have not been previously considered in portfolio risk allocation using cooperative game theory. We demonstrate the application through a simulation study. Our results show that considering assets weights could deliver added value when solving the low-risk puzzle.

    Dataset for "Targeted, receptor-mediated delivery of a masked ᴅ-amino acid cell penetrating peptide for cell-specific phototoxicity"
    (Universität Leipzig, 2025-11-06) List, Moritz; Jülke, Eva-Maria; Beck-Sickinger, Annette G.
    Photodynamic therapy is an innovative treatment option for cancer, but current approaches are limited by poor tumor selectivity and low uptake. Here, we introduce a novel concept for a targeted phototoxic peptide, in which a lysosomally activatable payload is delivered selectively by receptor-mediated endocytosis. For the payload, 6-carboxytetramethylrhodamine (TMR) was attached to an activatable cell penetrating peptide. The regular activity of the CPP was blocked by electrostatic interactions with a poly-glutamate sequence but could be restored through cleavage by the lysosomal protease cathepsin B both in vitro and in cells. The unmasked CPP can then bind to the negatively charged lysosomal membrane, and upon irradiation, TMR generates reactive oxygen species (ROS) that disrupt the integrity of the membrane. This leads to a release of lysosomal contents into the cytosol which subsequently induces cell death. To achieve targeted delivery, the activatable payload was conjugated to chemerin-9, a high-affinity ligand for the chemokine-like receptor 1 (CMKLR1), a G protein-coupled receptor overexpressed in various cancers. Through this receptor-targeted approach, the peptide accumulates in CMKLR1-expressing cells while the lysosomal activation completely prevented off-target toxicity. Notably, this strategy enables even a weak photosensitizer like TMR to achieve potent cytotoxicity through lysosomal targeting. This approach represents an advancement in improving the selectivity and efficacy of photodynamic therapy and holds promise for the development of novel cancer therapies. Furthermore, the concept opens possibilities for specific intracellular delivery of peptides or proteins.

    Supplemental material for the publication "Children born SGA receiving growth hormone have similarly impaired glucose-insulin metabolism as children with obesity"
    (Universität Leipzig, 2025-12-02) Prengemann, Lea; Stein, Robert; Gausche, Ruth; Beger, Christoph; Vogel, Mandy; Wenzel, Eric; Stoltze, Anette; Kiess, Wieland; Pfäffle, Roland; Körner, Antje
    Background and Objectives: Being born small for gestational age (SGA) and growth hormone (GH) treatment are linked to disturbed glucose-insulin metabolism. We investigated how GH treatment affects glucose-insulin metabolism in children born SGA compared to children with isolated growth-hormone deficiency (iGHD), obesity and lean controls. Methods: We analyzed glucose-insulin metabolism indices derived from OGTTs (Matsuda index, AUC insulin) and fasting parameters (fasting glucose, HOMA-IR) in 134 SGA patients without catch-up growth (CUG) receiving GH therapy (SGA-GHT), 27 untreated SGA patients with catch-up growth (SGA-CUG), 308 iGHD patients under GH treatment, 427 children with obesity and 356 lean controls. We adjusted for sex, age and BMI through matching and multivariable regression. Results: Treatment-naïve SGA-GHT patients were more insulin-resistant than iGHD patients (higher insulin AUC (p=0.002) and HOMA-IR (p<0.001), lower Matsuda index (p<0.001)) with levels approaching those of the obesity cohort. Under GH therapy, HbA1c was higher in SGA-GHT and iGHD patients (5.26%±0.35 vs. 5.25%±0.25) than in lean controls (5.09%±0.27). Insulin resistance in SGA-GHT patients approached levels seen in obesity. The prevalence of prediabetes was highest in SGA-GHT children (11.11%) compared to those with iGHD (1.59%) or obesity (3.13%). After stopping GH therapy, SGA-GHT patients retained elevated markers of prediabetes (4.65%) and insulin resistance compared to controls and iGHD patients, similar to children with obesity (6.38%). No overt type 2 diabetes was observed. Conclusion: SGA patients have an impaired glucose-insulin metabolism similar to that of children with obesity, which worsens under GH therapy. Close metabolic monitoring of GH-treated SGA patients is recommended.
