Item Open Access Localized actin cortex perturbation generates cell-scale membrane tension gradients(Technische Universität Dresden, 2026-10-27) Panda, Yogishree ArabindaMembrane tension is a key mechanical regulator of cell signaling, morphology, and division. Whether cells can sustain spatial gradients in membrane tension, or whether such asymmetries are rapidly dissipated by long-range tension propagation, remains actively debated. Here, we use the tension-sensitive fluorescent probe FliptR to directly measure changes in in-plane membrane tension following localized optogenetic activation of RhoA in mitotic HeLa cells. We find that local RhoA activation induces a sustained, cell-scale gradient in FliptR lifetime, consistent with a cell-scale in-plane membrane tension gradient and tension elevation on the non-activated side. This gradient depends on an intact actin and microtubule cytoskeleton and is accompanied by polarized cytoskeletal remodeling, with cortical F-actin enrichment at the activation site and asymmetric microtubule growth on the opposite side. AFM tether-force measurements reveal increased tether forces at the activated side, indicating locally enhanced membrane–cortex coupling. A coarse-grained membrane chemical-potential model explains how spatially heterogeneous membrane–cortex coupling can maintain such gradients. Together, our findings show that cells can actively generate and sustain spatially patterned mechanical states through localized cytoskeletal signaling.Item Open Access Data corresponding to: Confirmation of complex non-collinear Fe(II) spin ordering in the iron oxychalcogenide La2O2Fe2OSe2 by broad range 139La-NQR(Technische Universität Dresden, 2026-10-27) Weinhold, Tillmann; Seewald, Felix; Herrmann, CorneliusThe dataset contains NMR/NQR and Mössbauer data that is presented in Confirmation of complex non-collinear Fe(II) spin ordering in the iron oxychalcogenide La2O2Fe2OSe2 by broad range 139La-NQR.Item Open Access Quellcode und Datenmodell der Forschungsdatenbank Schwingfestigkeitsversuche für Wellen und Welle-Nabe-Verbindungen(Technische Universität Dresden, 2026-10-23) Becker, NilsDer vorliegende Datensatz beinhaltet den Quellcode der Datenbankanwendung (Quellcode.zip), das zugehörige Datenmodell in unterschiedlichen Formaten und ein Backup der Datenbank mit vorliegenden Daten aus mehreren Forschungsprojekten zum Stand Februar 2026.

This dataset provides LiDAR point clouds of a forest scene in the Richterschlüchte area, Saxon Switzerland, Germany, acquired during a field campaign in March 2023 using three different laser scanning systems: mobile laser scanning (MLS), uncrewed aerial vehicle laser scanning (ULS), and terrestrial laser scanning (TLS). All point clouds were manually annotated with three semantic classes, namely trunk, ground, and miscellaneous. In total, five point clouds are included: the MLS point cloud is partitioned into training, validation, and test subsets, while the TLS and ULS point clouds are provided to assess generalization across varying sensing systems. The dataset is intended for developing and testing deep learning approaches for the semantic segmentation of point clouds in complex forest environments.Item Open Access Data corresponding to publication: “Emergent relativistic symmetry from interacting fermions on the honeycomb bilayer” by Z.

The data is the calibrated and filtered data of these sensors with different evaluations carried out and stored in the files corresponding to the individual experiments.Item Open Access Datasets for paper "Discovering Encrypted Client Hello Deployments by Active ECH Probing"(Technische Universität Dresden, 2026-10-13) Mücke, Jonas; Gasser, Konstantin; Schmidt, Thomas C.; Wählisch, MatthiasThis data is supplement to https://doi.org/10.5281/zenodo.22012700 and contains the necessary data to recreate plots and tables of the following paper: Jonas Mücke, Konstantin Gasser, Thomas C. Schmidt, and Matthias Wählisch. 2026. Discovering Encrypted Client Hello Deployments by Active ECH Probing. In Proceedings of the 2026 ACM Internet Measurement Conference (IMC '26). Association for Computing Machinery, New York, NY, USA, 276–286. https://doi.org/10.1145/3777912.3839832 Paper abstract: We present a new measurement method to detect ECH deployments. This method leverages standard-compliant behavior of ECH servers. Prior measurements relied on DNS exposure and reported only one major ECH deployment (Cloudflare). Our measurements reveal yet undiscovered ECH deployments, including a large deployment at Meta. Meta servers support ECH, but ECH configuration is not exposed via the DNS. We also empirically study details such as the level of privacy improvement and latency impact of ECH.Item Open Access Temporal Visuo-Tactile Learning for Dexterous Grasp Stability(Technische Universität Dresden, 2026-10-08) Nakahara, Ken; Buvailik, Aleksei; Kotov, Prokhor; Calandra, RobertoThis dataset contains 10,000 multimodal robotic grasp trials across 200 everyday objects with diverse shapes, sizes, materials, and compliance, collected for the paper Temporal Visuo-Tactile Learning for Dexterous Grasp Stability. The platform combines a 7-DoF xArm7, a four-fingered, 16-DoF Tilburg Hand with a Digit 360 tactile sensor on each fingertip, and an external RealSense D435i RGB-D camera. Each trial continuously records external RGB-D observations, arm and hand proprioception, tactile images, audio, inertial measurements, pressure, and commanded actions throughout the full grasp attempt, from reaching and hand closure to lifting and post-lift outcome checking. The recordings include phase annotations and binary grasp-stability labels indicating whether the object was successfully lifted and held for three seconds without dropping. Timestamped, asynchronously recorded observations and actions, together with phase start times, allow selected intervals to be resampled into synchronized multimodal sequences; the pre-lift window used in the paper is one such example. The release also provides object reference images, per-object metadata, and Python tools for data visualization and resampling into training-ready samples. These full-grasp recordings support reuse beyond the prediction setting studied in the paper, including action-conditional grasp stability prediction, contact dynamics modeling, and multimodal representation learning for dexterous manipulation.Item Open Access Data corresponding to publication: "Emergent chiral metal near a Kondo breakdown quantum phase transition" by T.

However, modal dispersion leads to crosstalk effects. Robust mode decomposition is therefore crucial—whether to harness the inherent mode mixing for physical layer security (PLS) or to correct it in spatial division multiplexing (SDM). While traditional holographic methods can untangle this crosstalk, they require a stable reference beam, which is impractical for longhaul transmission due to environmental sensitivity. Furthermore, although recent deep-learning approaches enable reference-less decomposition, they typically suffer from high computational latency and massive training costs for dynamic channels. To overcome these limitations simultaneously, we propose a reference free, low-latency method for mode decomposition and channel reconstruction that leverages the linear complex scattering of the MMF as a passive high-dimensional spatial feature map, whose nonlinearity is provided by square-law detection at the camera. Following a reduction of the sampling rate in the frequency domain to decrease feature dimensionality, a computationally efficient linear readout layer inverts the scattering process to reconstruct the transmitted complex fields. Although the final channel reconstruction still requires digital computation steps, this readout process is limited to a single, computationally efficient linear matrix multiplication. This reduces both latency and computational overhead compared to conventional electronic neural networks, which typically exhibit high energy consumption and high latency. The physical limitations and trade-offs of this framework when scaling to higher modal complexities are also discussed. We experimentally demonstrate high-precision, reference-less mode decomposition for multiplexed classical optical fields.Item Open Access RNAseq data for Hassani et al. "Environmental enrichment regulates inter-individual transcriptional variance in the hippocampus"(Technische Universität Dresden, 2026-09-28) Kempermann, Gerd; Rünker, AnnetteGenetically identical mice housed in the same enriched environment (ENR) develop divergent behavioural trajectories associated with differences in adult hippocampal neurogenesis and brain-wide connectivity. We asked whether such inter-individual differences are also reflected in the hippocampal transcriptome—not only as shifts in mean expression, but as effects on within-group variability. Analysing bulk hippocampal RNA-seq from isogenic standard- (STD) and ENR-housed mice, we identified highly variable genes (HVGs) that segregated into common, STD-specific and ENR-specific subsets. ENR did not uniformly increase transcriptional variability: it reduced highest variability in neuron-projection and synapse genes, while maintaining or increasing it in genes linked to extracellular matrix organization and oxidative phosphorylation. Mapped onto a WGCNA-derived ENR co-expression reference, HVGs were unevenly distributed across modules and concentrated at module hubs. Hub architecture and the position of non-hub HVGs differed between modules, corresponding to distinct functional programs: synaptic and chromatin-associated in two, RNA-processing and splicing in a third. Synaptic enrichment in STD-specific HVGs, extracellular-matrix enrichment in common HVGs and module-level localisation were stable across selection thresholds (5–20%). Hippocampal transcriptional variability is thus non-random, functionally coherent, embedded in co-expression architecture and shaped by environmental experience—suggesting it is an undervalued activity-dependent variable in the regulation of brain plasticity.Item Open Access Data for "Competing magnetic and spin vestigial orders from continuum field theory"(Technische Universität Dresden, 2026-09-23) Francini, Niccolò; Janssen, LukasThe archive contains the data used to construct Fig.1 and 7 of the manuscript "Competing magnetic and spin vestigial orders from continuum field theory" by N.

Measurements were performed using the Thorlabs Telesto PSOCT system, operating at a central wavelength of λ̄ = 1300 nm, with an axial resolution of 4.2 µm in water and a lateral resolution of 12.2 µm. The A-scan pixel size is 3.473 µm, with a spatial sampling of dx = 5 µm in the fast scan direction and dy = 5 µm in the slow scan direction. The dataset includes two separate CSV files per volume scan: one for the co-polarized (co) channel and one for the cross-polarized (cross) channel. Each file contains 1024 rows corresponding to the 1024 A-scan components, with 1000 columns representing individual A-scans forming a single B-scan. A total of 800 B-scans are included in the dataset. The complex-valued data represent the product of amplitude and complex phase, enabling advanced analysis such as quantitative phase imaging, birefringence mapping, and tissue characterization. This dataset supports the validation and further development of the sPST (simplified Polarization-Sensitive OCT Technique) method and serves as a valuable resource for research in dental materials science, early caries detection, and optical imaging of hard tissues.Item Open Access Data corresponding to publication: "Field-driven phases in a three-dimensional twisted Kitaev model for CoNb2O6: Interplay of frustration and spin-orbit coupling" by T.

The bridge is a prestressed concrete bridge consisting of three spans, each with a length of 15 m. The bridge deck comprises three prefabricated T-beam elements. For the investigations, only Spans 1 and 2 were equipped with accelerometers, as Span 3 is structurally decoupled. The dataset consists of three different ensembles: the Reference State (RS), in which the bridge is in an undamaged condition, Damage State 1 (DS1), and Damage State 2 (DS2). Following the acquisition of the RS measurements, damage was introduced in Span 2 of the OpenBridgeLAB. A second damage was subsequently introduced in Span 1 after the measurements for DS1 had been captured. A detailed description of the damage scenarios and their locations is provided in the companion paper. In addition to the dataset, a datasheet is provided. The datasheet contains a detailed description of the measurements, including the sensor positions, sampling rate, number of measurements, and data structure. This research is part of the SPP100+ Priority Programme funded by the German Research Foundation.Item Open Access Development and Evaluation of a Virtual Reality Environment for Geometry Education: A Design-Based Research Study(Technische Universität Dresden, 2026-08-28) Josupeit, Judith; Arlt, Annika; Greiß, Annika; Dyrna, Jonathan; Köhler, ThomasVirtual reality (VR) offers new possibilities for geometry education by enabling learners to explore three-dimensional objects in spatially coherent environments. Despite these benefits, curriculum-related and theory-informed VR learning environments for lower secondary geometry remain limited, especially regarding formative evidence on users’ perceptions and design-related refinement needs. Thus, this study presents the development and formative evaluation of a VR learning environment for lower secondary geometry education, using a design-based research approach. In the environment, learners explored a virtual house and solved geometry tasks related to the geometric properties of the building and its surroundings. The evaluation comprised two phases with 48 participants in total. Quantitative questionnaire data and qualitative feedback were analyzed to examine perceived usability, cybersickness, cognitive load, motivation, perceived learning, didactic suitability, and design-related refinement needs. Overall, participants evaluated the environment positively. Ratings indicated low cybersickness, favorable perceived ease of use, low extraneous cognitive load, high learning-relevant effort, and high intrinsic motivation. Qualitative feedback showed that participants valued spatial exploration and perspective-taking, but also identified needs for more interaction, improved documentation of intermediate results, integrated feedback, and feasible classroom implementation.
