The test program was structured as follows: - Day 1 (2025-05-05): Static and dynamic measurements in the reference state - Day 2 (2025-05-06): Loading of the bridge using hydraulic jacks up to the ultimate limit state - Day 3 (2025-05-07): Localized damage to the prestressing tendons (cutting wires at multiple locations) This dataset includes three finite element (FE) models of the openLAB research bridge which were used to simulate the load tests conducted on Day 2. The load was applied locally to the prestressed element (PE) 2.1 (span 2, PE axis 1) using two hydraulic jacks, incrementally increasing the load up to a total of 400 kN. The three FE models were independently developed using different FE software solutions and feature different element types: - FE model 1: ATENA, volume element model - FE model 2: DIANA FEA, volume element model - FE model 3: SOFiSTiK, combined beam-shell element model The dataset includes all necessary input files to recreate the FE models in their respective software environments and reproduce the simulation results of the load tests.Item Open Access Training Data Set for U-Net Training based on Experimental Measurement using High Speed Camera(Technische Universität Dresden, 2026-04-10) Guesmi, Montadhar; Manthey, Johannes; Pani, Souman Kumar; Kupfer, Oliver; Dubbert, Manuel; Unz, Simon; Beckmann, MichaelBoundary detection using a trained U-Net model.

ResNet‑based classifiers are widely used for image‑recognition tasks , making them well‑suited for distinguishing subtle MRD‑related patterns in UMAP‑transformed cytometry data. The pipeline consists of a small collection of Python and R scripts organized as a lightweight workflow, following the standard idea of pipelines as sequences of data‑processing and prediction steps . Included in the repository are: - a single example patient dataset (raw data, pre‑processed data, and generated image) - an R script for preprocessing the raw flow‑cytometry data - a Python script that converts the tabular preprocessed data into 2D images - the representative UMAP embedding needed for generating standardized 2D representations of patient-specific data - a Python script that loads the ResNet‑34 architecture (including the custom classifier head), initializes the trained weights , and runs the prediction procedure to distinguish MRD‑positive from MRD‑negative image patterns This example is intentionally minimal: it is not a production‑ready pipeline but an educational demonstration of how the core steps—data preparation, image generation, and model prediction—link together in a transparent, reproducible workflow.Item Open Access Dynamic Spallation Energy Dissipation: Evaluation Methods for Split Hopkinson Bar Tests _ Dataset.rar(Technische Universität Dresden, 2026-03-11) Davoudkhani, Milad; Maca, Petr; Krcmarova, Nela; Beckmann, Birgit; Maas, Hans-GerdThis dataset comprises the data of the study on Dynamic Spallation Energy Dissipation: Evaluation Methods for Split Hopkinson Bar Tests. In this study, we employ a single high-speed camera setup with photogrammetric methods. The approach is based on enhanced inverse spatial resection principles for 3D tracking from single camera image sequence data and on Structure-from-Motion techniques for 3D shape reconstruction of multiple fragments produced in split Hopkinson bar impact experiments. These fragment shape and motion data allow to estimate the energy of each fragment, providing a key component in the analysis of energy dissipation.Item Open Access Test data for ICPR 2026 - RARE-Vision Competition(Technische Universität Dresden, 2026-03-09) Le Floch, MaximeThe RARE-VISION test dataset consists of three previously unseen capsule endoscopy examinations acquired with the Navicam system at the University Hospital Carl Gustav Carus, Technical University of Dresden. The dataset is strictly separated from the development data, and ground-truth annotations are withheld for final evaluation. Each case is provided as a complete chronological video sequence at a resolution of 480 × 480 pixels, preserving the original temporal order without trimming or manual segmentation. The three videos contain: 44,878 frames 53,220 frames 62,927 frames The data reflect real-world clinical variability and the natural class imbalance of capsule endoscopy, where rare pathological findings occur sparsely within long sequences of normal mucosa. Annotations are defined as temporal events (start frame, end frame, label) corresponding to the 17 competition target classes. The label set includes anatomical regions and pathological findings only; no anatomical landmarks are annotated. The dataset is designed to evaluate robust rare-event detection, temporal consistency, and fully automatic inference on long sequential video streams. The videos are provided exclusively for scientific research within the scope of the ICPR 2026 RARE-VISION competition and must not be used for any commercial purposes. For detailed terms of use, please refer to the official competition report and documentation. This study was approved by the Ethics Committee of the University Hospital Carl Gustav Carus at the Technical University of Dresden on December 16, 2022 (Ethics ID: BO-EK-534122022), confirming adherence to the ethical principles of the Declaration of Helsinki. Due to the retrospective anonymization of the data and their collection during clinically indicated routine interventions, explicit consent was not required. This is additionally supported by the Ethics Committee’s approval, a consultation with the data privacy officer, and local law. Section 34, Paragraph 1 of the Saxon Hospital Act (SächsKHG) explicitly allows the collection and analysis of this type of data.Item Open Access Conductive Hydrogels for Exogenous Sensing and Cell Fate Control(Technische Universität Dresden, 2026-03-09) Akbar, Teuku Fawzul; Jimenez-Rodriguez, Carlos Alejandro; Biktimirova, Railia; Hermes, Ilka; Kurth, Thomas; Pham, My Duyen; Tsurkan, Mikhail; Friedrichs, Jens; Morgan, Francis L. C.; Kleemann, Hans; Guskova, Olga; Freudenberg, Uwe; Fratzl, Peter; Werner, Carsten; Tondera, Christoph; Minev, Ivan R.Next generation technologies linking living systems to computers will require materials built on biology, an approach that may address persistent challenges in stable and multimodal information exchange. Here, we present a semi-synthetic hydrogel, designed to emulate key features of native extracellular matrix (ECM) while offering electrically tunable functionality. We engineer interactions between sulfated glycosaminoglycans (sGAGs) and a semiconducting organic polymer (Poly(3,4-ethylenedioxythiophene), PEDOT) within a soft hydrogel network (PEDOT:sGAGh). We demonstrate control over the material’s nanoarchitecture, electrochemical behavior, and biomolecular interactions. In particular, PEDOT:sGAGh exhibits affinity for bioactive proteins, including growth factors, and allows their release or retention to be modulated by low-voltage stimulation. This enables electrical control over macromolecular cues for cell differentiation, a capability not found in natural ECM or conventional conductive hydrogels. These functions are achieved with ultra-low PEDOT content (≈ 1 wt.%), preserving the hydrogel’s tissue-like softness and high water content. The PEDOT:sGAGh material can be integrated as a bioactive coating on electrodes, or into three dimensional organic electrochemical transistors (OECTs). Our results position PEDOT:sGAGh as a versatile platform for realizing biohybrid circuits that bridge molecular signaling and solid-state electronics, thus paving the way for brain-machine interfaces that operate beyond purely electrical modes of interaction.Item Open Access Spin-liquid-like ground states in the double hydroxyperovskites CuSn(OD)6 and MnSn(OD)6 evidenced by μSR spectroscopy(Technische Universität Dresden, 2026-02-27) Naskar, Moumita; Kulbakov, Anton A.; Parui, Kaushick K.; Krieger, Jonas A.; Hicken, Thomas J.; Luetkens, Hubertus; Häußler, Ellen; Doert, Thomas; Peets, Darren. C.; Klauss, Hans-Henning; Inosov, Dmytro S.; Sarkar, RajibDouble hydroxide perovskites with magnetic transition-metal ions were recently identified as a unique class of materials that combine magnetic frustration with correlated proton disorder—a prerequisite for quantum-disordered fluctuating magnetic ground states resembling spin liquids. Here we present the results of muon spin relaxation (μSR) measurements carried out on fully deuterated samples of the double hydroxyperovskites CuSn(OH)6 (S = 1/2) and MnSn(OH)6 (S = 5/2) over the temperature range 0.053–50 K. The absence of any long-range magnetic order is confirmed down to 0.053 K. We observe no oscillations of the muon asymmetry down to the lowest temperature. The muon relaxation rates show a continuous increase with decreasing temperature, indicating persistent spin fluctuations in both compounds. Spin correlations are consistent with homogeneous spin dynamics. These observations reinforce the assertion that both compounds have a quantum-dynamic magnetic ground state that is consistent with a spin-liquid-like phase stabilized by proton disorder.Item Open Access Structure from motion cross-scale dataset on agricultural areas in eastern Germany over a period of 3.5 years – plot scale, single slope scale, and catchment scale(Technische Universität Dresden, 2026-02-05) Epple, Lea; Eltner, Anette; Grothum, Oliver; Bienert, AnneThis study presents a unpresented approach to enhance soil erosion modelling through the utilisation of nested high-resolution spatio-temporal data obtained through structure from motion (SfM) photogrammetry. This technique permits comprehensive observation of soil surface elevation changes during precipitation events, encompassing data acquisition at diverse scales, from plot to slope to micro-catchment. The study presents a unique dataset that integrates high-resolution time-lapse photogrammetry, field measurements, and UAV (uncrewed aerial vehicle) photogrammetric data, collected over nearly four years. This dataset is intended to enhance the understanding of soil erosion processes and serve as a valuable resource for model evaluation and calibration. The authors encourage the broader scientific community to utilise and expand this dataset, which is expected to contribute to the development of more accurate soil erosion models, thereby improving predictions and management strategies.Item Open Access Photogrammetric data of circular target test fields for eccentricity analysis(Technische Universität Dresden, 2026-01-30) Liebold, FrankThis data publication contains photogrammetric data of test fields of circles. Please download the zip files and extract them. There are three experiments: Experiment 1 (in "exp1_planar_test_field.zip"): A planar test field with 20 concentric circle targets. The 12 larger circles have inner radii of 15mm, outer radii of 30mm and a grid size of 67mm. There are 8 further smaller circles (inner radius: 3mm, outer radius: 6mm).

Gleichzeitig müssen sie sich an die fortschreitende Entwicklung der Transport- und Beförderungstechnologien anpassen. Um diese Anforderungen zu erfüllen, spielt die technische Ausrüstungsart der Gleisoberbauanlagen – unter Berücksichtigung der Lebenszykluskosten – eine zentrale Rolle. Der Gleisoberbau unterscheidet grundsätzlich zwei etablierte Bauformen, den Schotteroberbau und die Feste Fahrbahn. Beide Systeme bieten jeweils spezifische Vor- und Nachteile. Aus ingenieurtechnischer Sicht ist es daher sinnvoll und zielführend, aus den beiden bestehenden Oberbauformen eine hybride Oberbauvariante zu entwickeln, die die Vorteile beider Konzepte vereint und ihre Nachteile weitgehend eliminiert. Diese hier entwickelte Wartungsarme Oberbauform verfolgt genau diesen Ansatz. In zwei neu entwickelten Prüfverfahren konnte einerseits eine deutlich geringere Setzungsaffinität des wartungsarmen Oberbaus im Vergleich zu der des Schotteroberbaus nachgewiesen werden. Andererseits wurden die Dauerfestigkeit und die zu erwartende Betriebsdauer des Schienenstützpunktes (Direct Fixation Fastener 304 IVES) ermittelt. Zur vergleichenden Bewertung der Lebenszykluskosten von Schotteroberbau, Fester Fahrbahn und Wartungsarmen Oberbau wurde eine Software entwickelt, die eine schnelle, auf den Belastungen basierende Berechnung ermöglicht. So konnte unter einer angenommenen 50%-igen Integration des Wartungsarmen Oberbaus in das Streckennetz der DB InfraGO AG eine fundierte Lebenszyklus-Analyse durchgeführt werden. Bei positiver Akzeptanz der Ergebnisse und einer effektiven Umsetzung im Bereich der DB InfraGO AG könnten Einsparungen von etwa 200 Mio. Euro pro Jahr realisiert werden. Dies würde einen wertvollen Beitrag zur Verbesserung der Mobilität in der Gesellschaft leisten.Item Open Access Aircraft Cabin Localization Dataset(Technische Universität Dresden, 2026-01-26) Schwarzbach, Paul; Muhammad, AmmadThis repository contains real-world indoor localization measurements collected in a realistic aircraft cabin environment. The dataset includes measurements from two distinct positioning systems: Ultra-Wideband (UWB) and Bluetooth Low Energy (BLE) provided in both CSV and Pickle formats.Item Open Access Data corresponding to paper: "Triaxial Compression of Sand‑Fines Mixtures at Low Confining Pressures" by Ullmann et al. (2025)(Technische Universität Dresden, 2026-01-21) Ullmann, Sebastian Pierre; Schmidt, Selma; Hartung, Felix; Herle, IvoThis data publication contains the data related to the scientific contribution "Triaxial Compression of Sand‑Fines Mixtures at Low Confining Pressures" by Ullmann et al. (2025) Abstract of the corresponding paper: A series of triaxial compression tests was performed on a natural sand-fines mixture under both drained and undrained conditions at initial confining pressures ranging from 20 to 300 kPa. The tests aimed to better understand the mechanical behaviour of the soil at low stress levels. Additionally, images of the soil fabric were taken using a μCT device, revealing that the fabric was characterised by the sand grains being fully embedded within the fine-grained matrix and that only few direct contacts between the sand grains existed. The results of the triaxial tests showed that the fabric of the sand-fines mixture significantly influenced the macroscopic properties of the specimens when compared to clean sands. In the drained triaxial tests, the dilatancy and friction angles showed minimal dependence on the confining pressure, even at pressures below 60 kPa. The undrained triaxial tests showed different response patterns in the development of excess pore water pressure. Tests starting from lower confining pressures resulted in a greater build-up of pore water pressure after reaching the phase transition line, whereas at higher confining pressures the soil exhibited lower excess pore water pressures.Item Open Access BaFe11TiO19 Vortex EMCD(Technische Universität Dresden, 2026-01-08) Pohl, Darius; Makino, Hitoshi; Ernst, Arthur; Negi, Devendra; Schneider, Sebastian; Erni, Rolf; Rusz, JanWe demonstrate atomic-scale mapping of local magnetic moments and doping effects in Ti-doped barium hexaferrite (BaFe11TiO19) using atom-sized electron vortex beams (EVBs) with controlled orbital angular momentum (OAM) in a scanning transmission electron microscope. By measuring electron energy loss magnetic circular dichroism (EMCD) at the Fe − L2,3 edges, we directly resolve the spatial distribution of antiparallel-aligned magnetic sublattices and quantify the impact of non-magnetic Ti4+ substitution. The EMCD signal, detected from single atomic Fe columns, reveals a marked reduction and sign reversal in the magnetic moment at Ti-rich 4f2 sites, corroborated by inelastic scattering simulations and density functional theory calculations that indicate induced Fe2+ formation and modified exchange interactions. Our results show that EVBs enable direct, element-specific, and atomically resolved magnetic characterization, opening new avenues for investigating local magnetic phenomena and dopant effects in nano-structured magnetic materials, such as those used in spintronic devices. This method paves the way for detailed studies of complex spin textures, magnetic interfaces, and dynamic processes at the atomic scale. Dataset includes raw data, DFT simulation of the DOS (BaFe12O19, BaFe11TiO19) and inelastic scattering simulation data.Item Open Access Fine root vitality decline results in reduced branch formation in mature beech stands after drought - Dataset(Technische Universität Dresden, 2026-01-06) Koller, Alexandra VivianClimate change is deteriorating the health, growth and thus functioning and services of forests through i.a. ongoing droughts, heatwaves and altered precipitation patterns, and an increase in the severity of these effects is predicted. Although fine roots can serve as an early indicator of drought stress, we still lack an understanding of how tree fine root vitality is reflected in aboveground tree morphology. Our study uses multitemporal fine root data obtained by sequential coring, as well as high-resolution tree crown data obtained by terrestrial laser scanning in mature European beech (Fagus sylvatica) stands. First, we assessed which fine root vitality traits are affected by drought, and second, evaluated the relationship between fine root vitality and crown vitality including trees within three different radial distances (5, 8 or 10 m) from the fine root sampling point. We found that fine root necromass, fine root biomass to necromass ratio and turnover were correlated with drought. Mainly fine roots in the upper 10 cm of soil affected the crown vitality of beech trees within a 5-m radius of the fine root sampling point, highlighting the tree-centred horizontal distribution of fine roots and shallow rooting pattern of beech. A decreased fine root vitality in the upper soil in the previous growing seasons led to decreased crown vitality. Including fine root inventories in forest monitoring protocols could substantially improve our understanding of the status and trends of forests and enable forest management to deal more effectively with the growing pressure on forests.Item Open Access LASANA: Laparoscopic Skill Analysis and Assessment video dataset(Technische Universität Dresden, 2025-12-26) Funke, Isabel; Bodenstedt, Sebastian; von Bechtolsheim, Felix; Oehme, Florian; Maruschke, Michael; Petzsch, Stefanie; Weitz, Jürgen; Distler, Marius; Mees, Sören Torge; Speidel, StefanieThe LASANA video dataset comprises 1270 trimmed and synchronized stereo video recordings of four basic laparoscopic training tasks (peg transfer, circle cutting, balloon resection, and suture & knot). Per task, there are at least 311 recordings in the dataset. Each recording is annotated with a structured skill rating, aggregated across three independent raters, as well as binary labels indicating the presence or absence of task-specific errors (for example, dropping an object during the peg transfer task, or puncturing the inner balloon during the balloon resection task). The LASANA video dataset is intended to support the development and evaluation of methods for automatic video-based laparoscopic skill analysis. For benchmarking, a fixed datasplit into training, validation, and test videos is provided for each task.Item Open Access Operational characteristics of a representative Hollow Cathode Electron Emitter (HCE) device with C12A7:e- emitter(Technische Universität Dresden, 2025-12-19) Berka, Elisabeth; Wulfkühler, Jan-Philipp; Tajmar, MartinIgnition and operation testing of the hollow cathode electron emitter (HCE) designed at the Institute of Aerospace Engineering of TUD Dresden University of Technology for the E.T.PACK-Fly in-orbit demonstration (IOD) mission with a C12A7:e- electron emitter. Testing conducted in triode mode with different laboratory electronics (e.g., 100–300 µF), krypton gas, and variable operating parameters (i.e., emission current and mass flow rate).Item Open Access Monitoring data to explore particle size distribution and elemental composition in a stormwater outlet from a German urban catchment(Technische Universität Dresden, 2025-12-19) Benisch, Jakob; Rojas-Gómez , Karen L.; Helm, Björn; Borchardt, Dietrich; Krebs, PeterThis repository presents a dataset comprising online monitoring turbidity and discharge data measured with a high temporal resolution at the stormwater outlet of a small urban catchment in Dresden, Germany. Additionally, for selected rainfall-runoff events, the following data were produced: total suspended solids concentrations and their particle size distribution (<63 µm: fine particles; >63 µm: coarse fraction), their elemental composition and organic content. The online monitoring data covers January 2018 - August 2022, whereas the sampled data were collected during September 2018 - 2021. These data are optimal for exploring flush dynamics, transport patterns of particles and particle-bound pollutants, and for developing and validating particle transport formulations in urban drainage models. This will allow a better identification of stormwater treatment and management strategies to effectively address different pollutant flushes, to support regulatory decision-making, and to minimise the impact of stormwater discharges on the receiving water bodies.
