Item Open Access Data from "Come fly with me" VR study on Reducing Cybersickness with Foveated Depth of Field Blur across varying Locomotion Control conditions(Technische Universität Dresden, 2025-12-03) Josupeit, Judith; Helmert, Jens; Hussain, Razeen; Solari, Fabio; Chessa, ManuelaCybersickness, which is characterized by symptoms such as general discomfort, headaches, and nausea, is a common issue in virtual reality (VR) that negatively impacts the accessibility and user experience. Foveated depth of field blur rendering (FovDof) uses the perceptual limitations of the human eye to mitigate cybersickness. However, the external validity of this countermeasure is limited. To increase the external validity, an interactive task is introduced. In addition, the study introduces two levels of locomotion control (3 vs. 6DoF). Along with subjective measures focusing on cybersickness symptoms (SSQ/MISC), objective performance measures (eye tracker sampling frequency) were analyzed. Based on valid data from 65 participants, the analysis revealed significant main effects for both rendering and locomotion control factors for the objective measures. However, the effects of the two types of measures are in opposite directions. For the subjective measures, the combination of full rendering and 3DoF locomotion control resulted in the highest cybersickness values. These results suggest that the applicability of FovDof is universal, even when a task is included, and can be implemented using other eye tracking software and hardware. However, limited customizability for VR headsets limits the applicability. In cases where full locomotion control is provided to the user, the FovDof algorithm does not have additional mitigating effects.Item Public Metadata Measurement Data for "An Analysis of Energy Efficiency Features in Intel Sapphire Rapids Processors"(Technische Universität Dresden, 2025-12-02) Schmidl, MarkusThis dataset contains performance measurement data which is used to classify internal mechanisms and characteristics that facilitate the tuning of energy efficiency on the Intel Sapphire Rapids processor generation.

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 with hydraulic jacks up to the ultimate limit state - Day 3 (2025-05-07): Local damage to the prestressing tendons (cutting wires at several locations) This dataset contains pictures of cracks in the precast element (PE) 2.1 during the load test 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 and increased in steps up to a total of 400 kN. The pictures were taken using a Dino-Lite AM4113T digital microscope connected to a laptop running the DinoCapture 2.0 software. One set of pictures was taken for each load step, before applying the load and during the plateau of constant deflection (5 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm).Item Open Access Weigh-in-Motion and Environmental Data from a German Highway(Technische Universität Dresden, 2025-11-13) Hagmanns, Moritz Peter Mathias; Jablkowski, Boguslaw; Hartung, Felix; Fazekas, Adrian; Oeser, MarkusWeigh-in-Motion (WIM) systems capture traffic-induced loads under real driving conditions, providing valuable insights into pavement loading. This dataset was collected within the DFG Collaborative Research Center SFB/TRR 339 “Digital Twin Road” using the project’s research WIM installation on the main lane of the A1/A61 highway near Erftstadt, Germany. It originates from Kistler’s KiTraffic Digital system and includes measurements from two sensor rows (four Lineas Digital sensors, type 9181A). Over a six-month observation period in 2025, 3.26 million vehicles with a total of 9.55 million axles were recorded. Each vehicle record provides detailed information on vehicle classification, loads, geometry, and tire-patch dimensions, which are rarely available from real-world WIM systems. In addition, separate environmental factors — such as asphalt and air temperature as well as solar irradiance — were recorded. The dataset supports analyses of load distributions, traffic composition, environmental factor, and speed characteristics, contributing to data-driven modeling of infrastructure loading and digital twins of road systems.Item Open Access Additional data to the publication "Characterization of cell adhesion phenomena at the dental abutment/soft tissue interface by means of a dynamic cell culture model"(Technische Universität Dresden, 2025-11-11) Angulo Salas, Laura Natalia; Kaiser, Friederike; Harrandt, Vaclav; Mehta, Kedar; Havlica, Jaromir; Wolf-Brandstetter, CorneliaThe paper describes the development of a flow chamber model for the assessment of cell adhesion strength under variable shear stress, her shown for human gingival cells to test cell adhesion phenomena under mechanical stress.

A detailed description of the data structure and image analysis workflow is provided in the accompanying README file. The macros used for image processing are published in Supplement 2 of the original publication. However, for convenience, they are also included here as standalone text files alongside a detailed instruction how to use the macros, assembled in the respective archive folder.Item Open Access Influence of various types of modification on the material behavior of bitumen(Technische Universität Dresden, 2025-11-11) Kamratowsky, Erik; Hartung, Felix; Leischner, Sabine; Zeißler, AlexanderThe present study investigated the influence of various types of modifications on the material behavior of bitumen. The stiffness behavior was examined using a temperature-frequency sweep, and the deformation behavior was examined using an adapted Single Stress Creep Recovery (SSCR) test. These tests were carried out on Anton Paar's Dynamic Shear Rheometer (DSR) utilizing the plate-plate geometry. The Anton Paar DSR was also employed to assess fatigue and low-temperature behavior, utilizing a solid-sample geometry. The tests are described in more detail in "Chemical and Mechanical Characterisation of Sbs-Modified Bitumen" by Kamratowsky et al. (submitted 2025).Item Open Access Data for "Left-Right Husimi Representation of Chaotic Resonance States: Invariance and Factorization"(Technische Universität Dresden, 2025-11-07) Lorenz, Florian; Schmidt, Jan Robert; Ketzmerick, RolandThis is the data for the figures in the paper "Left-Right Husimi Representation of Chaotic Resonance States: Invariance and Factorization" (New Journal of Physics 2025, arXiv:2507.10431 [nlin.CD]).Item Open Access Geometric-Semantic-Model and Platform for pavement loading and response monitoring of a German Highway(Technische Universität Dresden, 2025-11-06) Crampen, David; Hartung, Felix; Effkemann, Christoph; Becker, Ralf; Blankenbach, JörgThis data publication contains the data and derivatives corresponding to the geometric-semantic model generated as foundation for the interactive visualization of the Unreal engine-based digital shadow platform for sensor data management and simulation integration for the use case Weigh-in-Motion (WIM) and pavement response analysis. The Demonstrator "3D Interactive Visualization and Physical Mockup of a WIM Research Site" of the DFG Collaborative Research Center SFB/TRR 339 “Digital Twin Road” represents a case study for evaluating the feasibility of integrating multiple monitoring subsystems into a single source of truth representing the main components of a digital shadow system. The system integrates WIM system measurements, simulated pavement deformations and a real-time connection to a small-scale physical mock-up, where vehicle positions and proxy vehicle loading measurements can be monitored in real time. This demonstrates the feasibility of sensor data integration into a single-source-of-truth and linkage of real-time capable pavement analysis simulations into a high fidelity 3D monitoring environment, allowing interaction with the physical environment.Item Open Access Measuring active fluctuations of the cortex in mitosis by embedding an AFM cantilever pyrimidal tip(Technische Universität Dresden, 2025-11-04) Narinder, Narinder; Elisabeth, Fischer-FriedrichLiving cells exhibit non-equilibrium dynamics emergent from the intricate interplay between molecular motor activity and its viscoelastic cytoskeletal matrix. The deviation from thermal equilibrium can be quantified through frequency-dependent effective temperature or time-reversal symmetry breaking quantified e.g. through the Kullback-Leibler divergence. Here, we investigate the fluctuations of an AFM tip embedded within the active cortex of mitotic human cells with and without perturbations that reduce cortex activity through inhibition of material turnover or motor proteins. While inhibition of motor activity significantly reduces both effective temperature and time irreversibility, inhibited material turnover leaves the effective temperature largely unchanged but lowers the time irreversibility and entropy production rate. Our experimental findings in combination with a minimal model highlight that time irreversibility, effective temperature and entropy production rate can follow opposite trends in active living systems, challenging in particular the validity of effective temperature as a proxy for the distance from thermal equilibrium. Furthermore, we propose that the strength of thermal noise and the occurrence of time-asymmetric deflection spikes in the dynamics of regulated observables are inherently coupled in living systems, revealing a previously unrecognized link between entropy production and time irreversibility.Item Open Access Noise Estimation and Suppression in Quantitative EMCD Measurements(Technische Universität Dresden, 2025-11-03) Makino, HitoshiQuantitative electron magnetic circular dichroism (EMCD) in transmission electron microscopy (TEM) enables the measurement of magnetic moments with elemental and atomic site sensitivity, but its practical application is fundamentally limited by noise. This study presents a comprehensive methodology for noise estimation and suppression in EMCD measurements, demonstrated on Ti-doped barium hexaferrite lamellae. By employing a classical three-beam geometry and long-term acquisition of electron energy-loss spectra, we systematically analyze the signal-to-noise ratio (SNR) across individual energy channels using bootstrap statistics. A robust energy alignment procedure based on the neighboring Ba-M4,5 edges with an adequate energy upsampling is introduced to minimize systematic errors from energy misalignment. The impact of detector noise, particularly from CMOS-based EELS cameras, is evaluated through variance-to-mean analysis and described by the noise amplification coefficients, revealing that detector-amplified shot noise is the dominant noise source. We recommend a stricter SNR threshold for reliable EMCD detection and quantification, ensuring that critical spectral features such as the Fe-L2,3 peaks meet the requirements for quantitative analysis. The approach also provides a framework for determining the minimum electron dose necessary for valid measurements and can be generalized to scintillator-based or direct electron detectors. This work advances the reliability of EMCD as a quantitative tool for magnetic characterization at the nanoscale with unknown magnetic structures. The proposed procedures lay the groundwork for improved error handling and SNR optimization in future EMCD studies.Item Open Access Datasets for paper "Scanning the IPv6 Internet Using Subnet-Router Anycast Probing"(Technische Universität Dresden, 2025-10-30) Koch, Maynard; Hiesgen, Raphael; Nawrocki, Marcin; Schmidt, Thomas C.; Wählisch, MatthiasThis dataset is supplement to https://doi.org/10.5281/zenodo.17210253 and contains all the necessary data to re-create plots and tables of the following paper: Scanning the IPv6 Internet Using Subnet-Router Anycast Probing Maynard Koch, Raphael Hiesgen, Marcin Nawrocki, Thomas C. Schmidt, and Matthias Wählisch Proc. ACM Netw., Vol. 3, No. CoNEXT4, Article 50. Publication date: December 2025. https://doi.org/10.1145/3768997 Paper Abstract: Identifying active IPv6 addresses is challenging. Various methods emerged to master the measurement challenge in this huge address space, including hitlists, new probing techniques, and AI-generated target lists. In this short paper, we apply active Subnet-Router anycast (SRA) probing, a commonly unused method to explore the IPv6 address space. We compare our results with lists of active IPv6 nodes obtained from prior methods and with random probing. Our findings indicate that probing an SRA address reveals on average 10% more router IP addresses than random probing and is far less affected by ICMP rate limiting. Compared to targeting router addresses directly, SRA probing discovers 80% more addresses. We conclude that SRA probing is an important addition to the IPv6 measurement toolbox and may improve the stability of results significantly. We also find evidence that some active scans can cause harmful conditions in current IPv6 deployments, which we started to fix in collaboration with network operators.Item Open Access Research Data supporting the publication "Robust cytoplasmic partitioning by solving a cytoskeletal instability”(Technische Universität Dresden, 2025-10-23) Rinaldin, Melissa; Kickuth, Alison; Xu, Yitong; Brugués, JanThis dataset contains fluorescence imaging raw data and Python and ImageJ analysis scripts that were produced during the study of microtubule asters in frog egg extract and zebrafish and fruit fly embryos.

In the S = ½ system ktenasite, Cu₂.₇Zn₂.₃(SO₄)₂(OH)₆·6H₂O, we show that structural disorder drives an unexpected dimensional crossover and stabilizes a rare coexistence of distinct magnetic states. Neutron diffraction reveals significant Cu/Zn mixing at the Cu2 site, which tunes the Cu²⁺ sublattice from a two-dimensional scalene-distorted triangular lattice into a one-dimensional spin-chain network. Magnetic susceptibility, neutron diffraction, ac susceptibility, and specific heat measurements collectively indicate magnetic duality: a coexistence of incommensurate long-range magnetic order below TN = 4 K and a cluster spin-glass state with Tf = 3.28 K at f = 10 Hz. Our findings highlight ktenasite as a rare platform where structural disorder tunes the effective dimensionality and stabilizes coexisting ordered and glassy magnetic phases, offering a unique opportunity to explore the interplay of frustration, disorder, and dimensional crossover in quantum magnets.Item Open Access Wildfire Exposure Online Map(Technische Universität Dresden, 2025-10-08) Avouris, EvripidisThis interactive online map is accompanying the paper "Exposure of Settlements to Wildfires in a Transboundary Wildland-Urban-Interface Region in Central Europe" submitted to the NHESS journal, and was created to showcase exposure of settlements located within the boundaries of the Saxon/Bohemian Switzerland National Parks and the Conservation Areas of Saxon Switzerland and the Elbe Sandstone Mountains.Item Open Access Supplementary Material to the PhD Thesis "Microscopic investigations of the fiber architecture of the human tympanic membrane"(Technische Universität Dresden, 2025-10-07) Steuer, SveaThe Supplementary Material to the PhD Thesis "Microscopic investigations of the fiber architecture of the human tympanic membrane" contains volumetric raw data and additional videos and images which were created in the course of ex vivo investigations on human tympanic membranes with various optical imaging methods, i.e., polarization-sensitive optical coherence tomography (PS-OCT), second harmonic generation microscopy (SHG) and polarized light microscopy (PLM).

F.; Singer, L.; Mohamed, M. A. A.; Hampel, S.; Büchner, B.; Klingeler, R.; Klauss, H.-H.; Grafe, H.-J.The recently discovered lithium-rich antiperovskites (Li2Fe)SeO and (Li2Fe)SO host lithium and iron ions on the same atomic position which octahedrally coordinates to central oxygens. In a cubic antiperovskite these sites form Kagome planes stacked along the < 111 > directions which triangular motifs induce high geometric frustration in the diluted magnetic sublattice for antiferromagnetic interactions. Despite their compelling properties as high-capacity Li-ion battery cathode materials, very little is known about the electronic and magnetic properties of lithium-rich antiperovskites. We report static magnetization, Mössbauer, and NMR studies on both compounds. Our data reveal a Pauli paramagnetic-like behaviour, a long-range antiferromagnetically ordered ground state below ≈ 50 K and a regime of short-range magnetic correlations up to 100 K. Our results are consistent with a random Li-Fe distribution on the shared lattice position. In addition, Li-hopping is observed above 200 K with an activation energy of Ea = 0.47 eV. Overall, our data elucidate static magnetism in a disordered magnetically frustrated and presumably semimetallic system with thermally induced ion diffusion dynamics.
