Forecasting of the Traffic Situation in the Hannover Region

The main requirement of road traffic participants is to know the current traffic situation. Such data is typically obtained from routing services where the time of many different individual trips is taken into account.

In the context of Data4UrbanMobility tools were developed that allow to predict the traffic situation based on such time series data. The following figure presents an interface to visualize typical time series patterns as well as outliers present in the data:

The prediction of the traffic situation is made available in the form of a map based interface for the end user:

Data4UrbanMobility Data Protection Regulation

The work on the Data4UrbanMobility data protection regulation is completed. The document is publicly available and can be found here.

First Version of MiC-App Available

A first version of the novel MiC-App (Move in the City) App is now available for D4UM-associates as well as a protected group of public users. The mobile MiC-App is a tool to gather data.

MiC was developed by the Institute for Sustainable Urbanism at the University of Braunschweig and the Projektionisten GmbH. MiC links the growing  awareness of  digital citizen rights with the potential of evaluation big datasets. Therefore MiC gives the opportunity to citizen to actively participate in a citizen science project to take part in the development of the mobility of the feature.

MiC gathers data of the users movement, where the user has the about which data should be recorded. All data is pseudonymised such that the privacy of the contributing citizen is ensured.

Current Status:

In the first version of the app, the user can easily start and end the tracking of his/her movement. It is worth to point out, that the user decides when he is tracked and when not. A summary of his/her activity is available for the user as well as the opportunity to issue feedback or even delete all of his contributed data.

Updated System with Dashboard V2

With the new version of our system,  the dashboard will provide even more insights into the impact of public events on the traffic situation.

The coloring and labels let us easily distinguish between the different type of events. By clicking on the label we show the typically affected subgraph for that event type. This allows the user to check what specific routes are typically affected by an event at that location.

Examples: Visualisation of a concert and a football game.

In addition, the graph at the top right gives additional information on how big the impact around the events start time tends to be.

{API}
We enriched the api endpoints with additional information from the data models that were developed as part of the research efforts.

D4UM App Version 1.0

We just released the first Version of the D4UM App. Every project member now has access to the application and can try out its features. Let’s quickly go over some of its main features.
The EFA integration (EFA is a routing engine covering Lower Saxony and Bremen ) allows for quick access to tip information using all available public transport options. Our focus, when designing the application, was on quick and easy navigation to provide a simple and easy to use trip planning tool.

Departures and Connections

On the departure screen we show the user the closes stops for public transportation in his immediate vicinity. On the connection screen the user can fill in his desired starting location( either an address or an existing stop ) and destination and query for what connections are available to him. The provided information contains real time data , meaning we are able to visualized delays for any given connection.

Map

On the map screen you can see and or find all available stops of public transportation. This allows for providing the user with a great way to find out what stops are available in their city. By clicking on any of the shown stops will open the departure screen and provide you with the information mentioned above. To better visualize a selected connection, we show the route you plan to travel on the map.

Menu / Settings

Additional features can be found in the settings menu of the application. Here you can find settings that allow you to customize your routing results for both the departures and connection screen. The best way to let us know what you think about the application is to use the feedback module. This can be found here as well. First click on the emoji that best describe how you feel about the app. And then put in any additional information or ideas or thoughts you may have. Now what is left is just to press send and you will send us an email.

We look forward to hearing from you.

Quantification  and Prediction of Impact of Public Events

Current Data4UrbanMobility research results allow for measuring and prediction of spatial impact on road traffic of public events. Connected, affected street segments nearby public events are identified to measure the spatial impact. The approach is depicted in the following figure:

(Karte von https://www.openstreetmap.org)

An event is marked as yellow dot, affected streets in red and the measured impact in dark blue. Moreover, an approach making use of machine learning algorithms was developed to predict the impact determined in this way, resulting an error-reduction of up to 40% when compared to existing state-of-the-art approaches.

D4UM – Platform V1 Released

The first version of the Data4UrbanMobiltiy platform has been released. The platform was designed and implemented following a 3-tier-architecture. The platform provides RESTfull Web services for mobility applications like dashboards or mobile apps. As a demonstration, an interactive map application has been developed that visualizes the spatial impact of public events. The following figure shows a screenshot of the application.

The figure shows 4 public events in the city of Hannover. The colors represent different types of public events (e.g. concerts, fairs, sport events). The circles visualize the spatial impact on road traffic caused by the public events.

Comprehensive Set of Requirements

The Data4UrbanMobility analysis of requirements includes requirements of the application partners Region Hannover (RH) and Wolfsburg AG (WAG) as well as non functional requirements. The requirements were collected by MOMA. The L3S derived research question for data analysis which are based  on the requirements of RH and WAG. The research question address especially the information needs of end-users.

The current research questions particularly include

1. Automated verification of traffic warnings and prediction of their impact
2. Identification of events and prediction of their impact
3. Investigation of correlation of road traffic data, public transportation query logs, traffic warnings and twitterfeeds
4. Determination of optimal traveling timepoints

Growing Data Collection

ISU create a comprehensive data matrix containing potential source of mobility related data. The Data4UrbanMobility data model describes all project relevant data sets and sets them into context. This makes the data available in a unified manor for both analysis and applications. The selected data sources were transformed according to the Data4UrbanMobility data model by L3S. The data quality of selected data sources (i.e. public transportation query logs and road traffic data) was examined.

Tools for extracting the relevant information from the datasets were developed to enable the integration of the datasets.

• Street and graph extraction from OpenStreetMap
• Bulkloader for public transportation queries
• Integration of “Zentrales Haltestellen Verzeichniss” (central registry of public transportation stops)

The current collection (December 12th 2017) contians

EFA-Logs: 17 million public transportation queries
Road traffic data: 174 thousand street sements with a frequency of 15 minutes
GTFS-data: 90 thousand. public transportation stops, 2.6 thousand routes
Weather: Radolan “Regenraster” (rain grid)
Twitter: 2,5 Mio. Tweets starting at June 2017

OSM: 440 thousand streets 
Events: 21 thousand public events (August 14th 2016-July 17th 2018)

Traffic warnings: 13 thousand warning (since June 2017)

Visualization of Public Transportation Information

In order to allow intuitive analytics of public transportation information, the PROJEKTIONISTEN (PROJ) developed a dashboard web application. First prototypes visualize queries addressed to the regional timetable information system EFA (www.efa.de). The prototypes serve as foundations for exploration analyses as well as the implementation of future versions of the dashboard. The following figure shows an integrated visualization of the most frequent origins and destinations of the queries.

Analysen der EFA-Logs

Analysis of EFA Public Transportation Query Logs

Analyses regarding the impact of public events on public transportation are currently conducted to address early research questions. To this extend, explorative data analyses of the impact of major public events such as football games and medium sized events such as concerts were conducted. Visual analytics were used as a first step towards comprehensive analyses, which show start-like patterns for city center which identify mobility hubs of central importance.

The figure shows the direct connection between origin and destination of public transportation queries. Darker colors correspond to more frequent queried trips. Star-like pattern identify the central train station and the central metro station.

Analyses of single stations reveal weekday dependent patterns.

The figure depicts the average number of queries with the destination “Hannover Stadionbrücke”. Differences emerge between Weekends and workdays.

The impact of public events on the queries can be visualized  as well.

The figure shows the number of queries with the Destination “Hannover Stadionbrücke” for Wednesday, April 26th 2017 (orange) as well as the average number of queries on a Wednesday for the same destination. On this day a concert took place in venue nearby. The concert start at 8 pm. The significant deviations between 5 pm and 7 pm is highly likely to be caused by visitors of the concert. This shows that public transportation queries are a valuable information source to investigate the impact of public events on mobility infrastructure.

• Expanding the Late Quaternary morphochronology of Atacama’s coastal alluvial fans by Schmidt hammer exposure dating reveals spatially distinct genesis. Walk, Janek (2026). 21 100305.

  Late Quaternary alluvial fans along the coast of the hyperarid Atacama Desert have been exploited as palaeoenvironmental archives by several studies. However, a regional palaeoenvironmental interpretation remains challenging as established geochronological frameworks are based on a limited number of sites where fan aggradation was constrained by numerical dating. Consequently, it is unclear to what extent fan aggradation and progradation is controlled by large-scale allogenic versus individual autogenic forcing. To therefore expand the regional alluvial fan morphochronology along the south-central coast, the applicability of cost-effective Schmidt hammer exposure dating (SHD) was explored on boulders of plutonic lithology. The independently exposure-dated coastal alluvial fan (CAF) Paposo served as regional age-calibration site for SHD of 11 telescopic CAFs between 24.25°S and 25.25°S. SHD was complemented by the assessment of the CAFs’ terrestrial and shelf morphometry and the hydromorphometric and climatic catchment properties. The results of the successfully calibrated SHD suggest that weathering in the coastal desert allows for age ranges extending over the Late Quaternary. The expanded morphochronology reveals a distinct fan evolution segmenting a synchronous morphogenesis south of 24.85°S from a diachronous one in the north. Spatial segmentation is reflected in specific catchment hydromorphometric characteristics and differences in the relationships between terrestrial fan versus shelf gradients – the latter indicating a dominant allogenic control of eustatic sea-level changes at least in the south. While spatiotemporal variability in Late Quaternary precipitation and tectonic activity may constitute additional relevant factors, diachronism of northern CAF evolution could also be the response to individual autogenic fan dynamics.

  Miniature electronics positioned within textile braids leverages the persistent flexibility and comfort of textiles constructed from electronics with 1D form factors. Here, we developed touchless interactivity within textiles using 1D overbraided magnetic field sensors. Our integration strategy minimally impacts the performance of flexible giant magnetoresistive sensors, yielding machine-washable sensors that maintain conformability when integrated in traditional fabrics. These overbraided magnetoresistive sensors exhibit a detectivity down to 380 nT and a nearly isotropic magnetoresistance amplitude response, facilitating intuitive touchless interaction. The interactivity is possible even in humid environments, including underwater, opening reliable activation in day-to-day and specialized applications. To showcase capabilities of overbraided magnetoresistive sensors, we demonstrate a functional armband for navigation control in virtual reality environments and a self-monitoring safety helmet strap. This approach bridges the integration gap between on-skin and rigid magnetic interfaces, paving the way for highly reliable, comfortable, interactive textiles across entertainment, safety, and sportswear.

  Modern 3-D printing techniques enable the rapid prototyping of complex mechanical structures. We leverage this capability to create customizable pressure sensors by combining soft and ferromagnetic filaments during the printing process. The resulting inductive sensors utilize a lattice structure based on a body-centered cubic unit cell, exhibiting tunable stiffness with Young's moduli ranging from 112 to 368 kPa and sensitivities between \($-$\)0.17 and \($-$\)0.11% kPa\($^-1$\). The sensors show minimal hysteresis and remain stable throughout 10 000 compression cycles. The versatility of this approach is further demonstrated through the fabrication of a fully printed inductive joystick.
• Soft magnetic microrobots with remote sensing and communication capabilities.

  Remote communication in small-scale robotics offers a powerful way to enhance their capabilities, introducing options for state monitoring, multi-agent collaboration, and autonomous operation. Integrating common remote communication tools, such as antennas, into microrobots is challenging with conventional design and manufacturing techniques. We propose a concept that integrates shape-reconfigurable soft microrobots with flexible electronics, leveraging their elastic mechanical properties to enable remote communication. This approach, based on photolithography processes, is scalable and adaptable to various sensing applications. As a proof of concept, we present a microrobot, which integrates a thermoresponsive magnetic hydrogel, an anisotropic support structure, and a flexible dipole antenna into a cohesive three-layered design. The microrobot can morph from a helical shape at low-temperatures to a planar shape at high-temperatures. This shape transformation can be remotely detected by external radio communication receivers, enabling shape-state recognition and environmental temperature sensing. Furthermore, we show that the collective behavior of multiple microrobots enhances the recognition performance by amplifying the signal. The concept represents a significant advancement in co-engineering smart materials and flexible electronics, illustrating an approach of microrobotic embodied intelligence by integrating environmental monitoring, magnetic navigation, and remote signaling.

  The direct fabrication of thin-film transistors (TFTs) based on Indium-Gallium-Zinc-Oxide (IGZO) on a flexible polyurethane (PU) substrate is presented. Polyurethane, with its mechanical flexibility, durability, and potential for environmental sustainability, offers a promising platform for flexible electronics. Here, a custom polyurethane film was synthesized and a low-temperature fabrication process (T ≤130◦C) was developed for the realization of oxide-based electronics on this flexible material. The fabricated TFTs exhibited an effective mobility of 15.3cm2V−1s−1, an on/off current ratio exceeding 105, and a threshold voltage of 0.8V. Additionally, the devices demonstrated long-term stability, retaining functionality after over 12 years of storage. The performance of the TFTs on PU is also compared to similar devices realized on a variety of other polymer substrates. The results demonstrate the feasibility of integrating IGZO transistors on polyurethane substrates for flexible electronic applications. Hence PU can open up a path towards unobtrusive and environmentally friendly wearable systems exhibiting mechanical adaptability, long-term reliability, or repairability.

  This article explores the instability of threshold voltage ( \($V _\textit TH$\) ) and dielectric breakdown in flexible n-type thin-film transistors (TFTs) featuring a bottom-gate Ti/Al2O3/indium–gallium–zinc-oxide (IGZO) structure. Measurements were performed in dark conditions at \($25~^\circ $\) C on a set of devices with the same channel width ( \($W=280~\mu $\) m) and different channel lengths (L) ranging from 100 down to \($5~\mu $\) m. Regarding the \($V _\textit TH$\) instability, both hysteresis (applying \($V _\textit GS$\) from −1 to 5 V and vice versa) and positive gate bias stress (applying \($V _\text GS=5$\) V for 1000 s) data show a positive \($V _\textit TH$\) shift ( \($\Delta V _\textit TH$\) ) ascribed to electron trapping at the channel/oxide interface or within the bulk oxide. Our study also demonstrates that in some devices, the stress-induced \($\Delta V _\textit TH$\) is fully recovered by applying \($V _\textit GS=-2$\) V for 1000 s as a result of releasing charges previously trapped during stress. Moreover, measurements highlight an increasing trend of both hysteresis- and stress-induced \($\Delta V _\text TH$\) for shorter channel devices. Consistently, time-dependent dielectric breakdown data (applying VG = 11 V) indicate a faster process in smaller devices. Then, overall results show lower reliability in more scaled devices, thus proving that a key challenge for the investigated technology is to realize reliable short-channel TFTs.

• Outsourcing Domestic Work in the Crisis of Social Reproduction: Platform‐Mediated Cleaning and the Role of Clients. Gerold, Stefanie; Gruszka, Katarzyna; Sardadvar, Karin; Theine, Hendrik; Pillinger, Anna (2025).

  Amid the crisis of social reproduction, outsourcing domestic work has become increasingly appealing, with labour platforms offering new avenues to do so. This article explores the largely overlooked perspective of clients using platform-mediated cleaning services, focusing on Helpling in Germany. Drawing on a multi-method study, we examine clients’ motivations for hiring cleaners through platforms and their perceptions of working conditions. We also analyse interactions between clients and cleaners, and how these are shaped by the platform. Our findings suggest that platforms like Helpling are attractive because of their convenience and their promise of an allegedly legal alternative to informal arrangements. While some clients express concerns over precarious working conditions, others justify them through market logic or assumptions about cleaners’ backgrounds. The platform infrastructure helps mediate trust, yet personal relations between clients and cleaners limit the platform's strategy of delegating management and control mechanisms to clients.

  Developing novel biodegradable substrates for electronics is crucial for reducing e-waste, minimizing environmental impact, and promoting sustainable resource use. Here, for the first time, we report the use of Agave silk fibers (ASFs) in sustainable and flexible electronics. Morphological characterization was carried out on the obtained ASFs-based substrate, showing an average thickness of \($83 \mu \mathrmm$\) and an average roughness (\($R_a$\)) of \($2.6 \mu \mathrmm$\), with the silk fibers composing the substrate having an average length and width of \($243.8 \mu \mathrmm$\) and \($26.2 \mu \mathrmm$\) respectively. Biodegradability tests showed that the substrate fully degraded after 2 days and 7 hours in water. As a proof of concept, a copperbased resistance temperature detector (RTD) was fabricated and thermally characterized. The electrical characterization showed a sensitivity of \($0.26 \% ^\circ \mathrmC^-1$\) and \($0.24 \% ^\circ \mathrmC^-1$\) during heating and cooling, respectively. To evaluate the repeatability of the sensors, 10 cycles of heating (55° C) and cooling (25° C) were carried out, showing stable behavior for 7 h. To confirm the mechanical stability of the device, bending tests were performed, showing a stable resistance of the RTD at different bending radii.

  Transforming soft machines into fully autonomous soft robots capable of complex interactions with the environment requires the integration of soft electronics and sensors, enabling feedback control while preserving mechanical compliance. Multistable mechanisms, such as mechanical metamaterials and snapping beams, are great candidates for such systems due to their programmable nonlinear responses. In this work, we introduce the integration of a sensing technology based on 3D-printed soft capacitive sensor in a 3-D-printed multistable metastructure composed of four bistable unit cells—enabling proprioceptive monitoring of state transitions by detecting snap-through events in multistable mechanisms. Under cyclic tensile loading, the metastructure exhibits snapping events at forces up to 7 N, accompanied by capacitance changes from about 0.025 to 0.750 pF. We further demonstrate the integration of the same sensing principle in a 3-D-printed monolithic bistable soft gripper, reliably grasping delicate objects such as popcorns, tomatoes, and strawberries, spanning masses from 0.5 to 16 g. These results confirm that embedded capacitive soft sensors are a viable technology to detect snap-through transitions and to be seamlessly integrated in soft structures, representing a crucial step toward fully compliant, self-aware robotic systems.
• Flexible InGaZnO Thin-Film Transistors With Gelatin Gate Dielectric for Nonvolatile Memory. Konwar, Gargi; Lanthaler, Albert Heinrich; Singh, Ritesh Kumar; Catania, Federica; Münzenrieder, Niko; Cantarella, Giuseppe; Tiwari, Shree Prakash (2025). 4(5) 188–193.

  Recently, the use of natural materials in device fabrication has become a significant trend in advancing eco-friendly and sustainable electronics, to achieve technologies with low carbon footprints and yet reliable functionality. This work demonstrates utilization of gelatin, a natural protein, as a gate dielectric, in combination with indium gallium zinc oxide (InGaZnO) semiconductor, to fabricate top-gated flexible thin-film transistors (TFTs). More specifically, these devices exhibit nonvolatile memory characteristics for 10 V operation upon application of a voltage sweep of ±10 V, with a maximum memory window (MW) of \($\approx 12$\) V and repetition for 100 continuous scans. Moreover, consistent static retention was obtained with a current on-off ratio of \($\gt 10^5$\) for 3 h. The hygroscopic nature of gelatin enabled these devices to demonstrate reliable response as humidity sensor upon exposure to a humidity pulse (in the range between 42% and 90% relative humidity). In addition, TFTs demonstrated functionality during bending condition (down to 7 mm bending radius) with 8 months-long shelf-life.

  Sustainable leveraging of natural resources is imperative to move toward next-generation electronics, balancing functionality, affordability, and sustainability. In this perspective, the use of sustainable materials is an effective way to combine electronics development and low carbon footprint. Here, we successfully introduced thin-film resistance temperature detectors (RTDs) and thin-film thermistor sensors on a triacetyl cellulose (TAC) film derived from sustainable plant-based cellulose. These devices are tested in a temperature range of 25° C to 75° C, demonstrating average sensitivity of \($0.21 \% ^\circ \mathbfC^-1$\) for the RTDs, and \($0.26 \% ^\circ \mathrmC^-1$\) for the thermistors. Device performances are demonstrated while mechanical strain is applied, with reliable functionality down to 8 mm bending radii. Finally, device dissolution in deionized water revealed the transient nature of the thermistor sensor after 10 days. These results demonstrate the potential of a cellulose based substrate and its integration with thin-film devices for the realization of green and yet sustainable electronics.

  This study explores nature-based substrates as sustainable alternatives to traditional polymer-based materials for unobtrusive and flexible electronics. It focuses on the fabrication of thin-film temperature sensors directly on thin walnut wood substrates. This natural material combines mechanical flexibility, sustainability, and aesthetics. Metallic resistive temperature detectors (RTDs) and thermistors based on semiconducting Indium Gallium Zinc Oxide (IGZO) were fabricated by sputtering. Despite the high surface roughness of the substrate (\($>40 \mu \mathrmm$\)), both types of sensors exhibit functionality, with sensitivities up to 0.259% ° C−1 and stability over multiple temperature cycles. Furthermore, RTDs were bent to radii as small as 23 mm.

F.; Klein, Alexandra-Maria; Albrecht, Matthias (2025).

  Pesticide use and habitat loss are major anthropogenic drivers of bee decline, raising global concerns about impaired crop pollination. However, the relative importance of these stressors and their combined impact on bee assemblages comprising species with different traits, such as body size or nesting strategy, remains unknown. Here we addressed these key knowledge gaps in a global quantitative synthesis analysing bee assemblage data from 681 crop fields across three continents. We found that both local pesticide hazards and decreasing proportions of semi-natural habitats in surrounding landscapes negatively affected wild bee abundance and species richness in crop fields, while pesticides additionally reduced functional and phylogenetic diversity. Semi-natural habitat availability did not buffer against these negative pesticide effects, nor did we identify any specific traits rending bees more vulnerable to one of the two drivers. Our findings highlight the pressing need to reduce non-target effects of pesticide use and emphasize that conservation and restoration of semi-natural habitats successfully promote wild bees, but are insufficient strategies to mitigate pesticide-driven losses of wild bee pollinators from crop fields.
• Advxai in Malware Analysis Framework: Balancing Explainability with Security. White, Darring (D. White, ed.) (2025). 14(1)

  With the increased use of Artificial Intelligence (AI) in malware analysis there is also an increased need to understand the decisions models make when identifying malicious artifacts. Explainable AI (XAI) becomes the answer to interpreting the decision-making process that AI malware analysis models use to determine malicious benign samples to gain trust that in a production environment, the system is able to catch malware. With any cyber innovation brings a new set of challenges and literature soon came out about XAI as a new attack vector. Adversarial XAI (AdvXAI) is a relatively new concept but with AI applications in many sectors, it is crucial to quickly respond to the attack surface that it creates
• The Benefits of the EU Single Market: Evidence from the Gravity Model. Rybacki, Jakub; Sułkowski, Dawid (2025). 12(59) 284–294.

  Empirical economic studies based on gravity models have generally portrayed European integration in a highly positive light. However, the success of Eurosceptic parties in the German regional elections and the Dutch legislative elections highlights growing resistance to further integration. This phenomenon may be explained by the fact that the benefits of integration are often not immediately visible; they tend to manifest indirectly through increased trade volumes between member states. Nevertheless, these political outcomes also cast doubt on the reliability of modelling results, Therefore, our goal is to quantify the impact of EU membership on sectoral trade flows using a gravity model of foreign trade for the period of 2006–2017. To achieve this, we conducted over 850 regressions. Our analysis indicates that exports between EU member states are, on average, 20%–30% higher throughout the business cycle compared to similar non-EU countries. Additionally, we assessed the distribution of membership benefits across individual member states. Our findings reveal that Hungary, Slovakia, and Czechia experienced the most significant increases in trade with other EU countries.
• The Rise of "Self-Cleaning" Paint Technology. Akhiltomar (2025). (3) 3.

• Evaluación del personal académico y de investigación por amplificación de puntuaciones de acuerdo con su proximidad a objetivos institucionales. Santana Sepúlveda, Julio Sergio (J. González Candia, ed.) (2025). 18(53) 16–47.

  The issue of tension between the individual objectives of academic and research staff and the strategic objectives of the institution in which they work is addressed in this study, to develop a methodology for their appraisal that takes into account both individual objectives, in the context of academic freedom, and the above-mentioned institutional strategic objectives. To this end, a similarity metric is proposed, based on the Manhattan distance, to measure the proximity between individual and institutional objectives, which allows generating an amplification factor for individual scores. The new amplified score can be used to generate work incentives, such as job promotions or financial benefits.
• RLSUAV: Relative Localization in a Swarm of UAVS. Meghanathan, Natarajan (2025). (Vol. 17) 41–56.

  A swarm or fleet of Unmanned Aerial Vehicles (UAVs) can be used to accomplish several missions such as security, search and rescue or surveillance in unknown and dangerous environments. In order to deploy a fleet of drones for such applications, drones must be able to perform certain tasks, such as collision prevention, and formation flight with a leader node. These tasks are accomplished by knowing the location of neighboring drones in the group. The conventional method of determining the position relies mainly on the GPS system. Therefore, drone swarms relying on classical positioning methods (GPS) cannot operate in dense urban or in indoor environments, due to the difficulties encountered in receiving the GPS signal from the satellites. In these cases, relative localization can be used to help nodes without GPS to determine their positions. Relative localization uses cooperative communication and information sharing between nodes in the network to help them estimate their positions. In this paper, we propose a novel technique providing relative localization in a swarm of UAVs (RLSUAV) that does not require any GPS information and, therefore, can be used in indoor environments. It consists of estimating the positions of the drone nodes as a function of the distances measured between them, combined with the multilateration technique, where the distances between the drones are calculated using the power of the received signal (RSSI). Simulation results showed the effectiveness of RLSUAV in different environments (with and without multipath), achieving an estimation error inferior to 5 meters in most cases.
• Plasmonic Su–Schrieffer–Heeger chains with strong coupling amplitudes. Schurr, Benedikt; Hensen, Matthias; Brenneis, Luisa; Kessler, Philipp; Qin, Jin; Lisinetskii, Victor; Thomale, Ronny; Brixner, Tobias; Hecht, Bert (2025). 11(50) eaea3844-.

  Plasmonic many-particle systems with precisely tuned resonances and coupling strengths can exhibit emergent collective properties governed by universal principles. In one-dimensional chains with alternating couplings, known as Su?Schrieffer?Heeger (SSH) systems, this includes the formation of topologically protected mid-gap modes whose intensities localize at the chain?s ends. This subwavelength localization at optical frequencies is crucial for achieving strong coupling of mid-gap modes to two-level systems under ambient conditions, extending topological protection to hybrid light?matter states. Here, we have fabricated SSH chains from plasmonic nanoslit resonators with strong interresonator coupling. The alternating distance between the nanoslit resonators is controlled with subnanometer precision, enabling accurate prediction and experimental observation of topologically protected mid-gap modes via photoemission electron microscopy. Our results open the path toward experimental realizations of two-dimensional photonic metasurfaces exhibiting higher-order topological modes that can be strongly coupled to single emitters and quantum materials at ambient conditions. Strong coupling enables device-relevant spectral separation of broad, topologically protected mid-gap modes from band edges.
• Unify: Uncertainty incorporated Federated Learning for Object Detection. Gao, Shang; Sick, Bernhard; Götz-Hahn, Franz (2025). 330–344.

  Federated Learning (FL) has demonstrated promise for collaborative training on decentralized data while preserving privacy. However, applying FL to object detection remains challenging due to non-IID data distributions and domain shifts that can degrade performance with standard aggregation methods. To address these issues, we propose the Uncertainty Incorporated Federated Learning for Object Detection (Unify) framework, a novel FL framework that leverages Evidential Learning (EL) to estimate both epistemic and aleatoric uncertainties. By integrating these uncertainty estimates into the aggregation process, Unify down-weights unreliable client updates, leading to improved cross-domain generalization and enhanced stability. Built upon a lightweight YOLOX detector, our approach achieves detection performance that closely approaches centralized training while significantly outperforming conventional FedAvg under heterogeneous conditions. Evaluations on the KITTI and nuImages datasets demonstrate that Unify improves mean Average Precision (mAP) and yields uncertainties. The findings highlight the potential of uncertainty-incorporated FL in developing resilient, adaptive, and self-organizing computing systems.
• Altruistic disease signalling in ant colonies. Dawson, Erika H.; Hoenigsberger, Michaela; Kampleitner, Niklas; Grasse, Anna V.; Lindorfer, Lukas; Robb, Jennifer; Beikzadeh, Farnaz; Strahodinsky, Florian; Leitner, Hanna; Rajendran, Harikrishnan; Schmitt, Thomas; Cremer, Sylvia (2025). 16(1) 10511.

  Sick individuals often conceal their disease status to group members, thereby preventing social exclusion or aggression. Here we show by behavioural, chemical, immunological and infection load analyses that sick ant pupae instead actively emit a chemical signal that in itself is sufficient to trigger their own destruction by colony members. In our experiments, this altruistic disease-signalling was performed only by worker but not queen pupae. The lack of signalling by queen pupae did not constitute cheating behaviour, but reflected their superior immune capabilities. Worker pupae suffered from extensive pathogen replication whereas queen pupae were able to restrain their infection. Our data suggest the evolution of a finely-tuned signalling system in which it is not the induction of an individual's immune response, but rather its failure to overcome the infection, that triggers pupal signalling for sacrifice. This demonstrates a balanced interplay between individual and social immunity that efficiently achieves whole-colony health.

• DigSmart -- Unterstützung beim Baggern durch Laserprojektion. Anteunis, L.; Nüchter, A. (2025). 133(6) 171–180.

  Jedes Jahr entstehen mehrere Millionen Euro an Schaden durch Bagger. Dies liegt unter anderem an den fehlenden Verlaufsplänen auf den Baustellen. Das Projekt „Digitalisierung und Smart Services im Tiefbau“ untersucht, inwiefern die Visualisierung von Leitungen mithilfe eines Laserprojektors zum Einsatz kommen kann. Hierbei kommt ein Livox-Laserscanner zum Einsatz, um die Umgebung in der Projektion zu berücksichtigen. Um die Projektion unverzerrt darstellen zu können, führt der Algorithmus ein Raytracing- Verfahren durch, um die Projektion anzupassen. Dies setzt jedoch die extrinsische Kalibrierung zwischen dem Laserscanner und -projektor voraus. Die Experimente zeigen, dass die hier vorgestellte Methode den Projektor und Laserscanner erfolgreich kalibrieren kann und dass mit einem Root Mean Square Error von weniger als 40 mm eine genaue Projektion möglich ist. Die Projektionen im DigSmart-Projekt dürfen maximal 100 mm abweichen.

• The impact of habitat loss and population fragmentation on genomic erosion. Pinto, Alessandro V.; Hansson, Bengt; Patramanis, Ioannis; Morales, Hernán E.; van Oosterhout, Cock (2024). 25(1) 49–57.

  Habitat loss and population fragmentation pose severe threats to biodiversity and the survival of many species. Population isolation and the decline in effective population size lead to increased genetic drift and inbreeding. In turn, this reduces neutral diversity, and it also affects the genetic load of deleterious mutations. Here, we analyse the effect of such genomic erosion by designing a spatially explicit, individual based model in SLiM, simulating the effects of the recorded habitat loss in Mauritius over the past ~ 250 years. We show that the loss of neutral diversity (genome-wide heterozygosity) was barely noticeable during the first 100 years of habitat loss. Changes to the genetic load took even more time to register, and they only became apparent circa 200 years after the start of habitat decline. Although a considerable number of deleterious mutations were lost by drift, others increased in frequency. The masked load was thus converted into a realised load, which compromised individual fitness and population viability after much of the native habitat had been lost. Importantly, genomic erosion continued after the metapopulation had stabilised at low numbers. Our study shows that historic habitat loss can pose a sustained threat to populations also in future generations, even without further habitat loss. The UN’s Decade on Ecosystem Restoration needs to lead to transformative change to save species from future extinction, and this requires the urgent restoration of natural habitats.

  Recommendation Systems (RecSys) comprise a large footprint of production-deployed AI today. The neural network-based recommender systems differ from deep learning models in other domains in using high-cardinality categorical sparse features that require large embedding tables to be trained. In this talk we introduce TorchRec, a PyTorch domain library for Recommendation Systems. This new library provides common sparsity and parallelism primitives, enabling researchers to build state-of-the-art personalization models and deploy them in production. In this talk we cover the building blocks of the TorchRec library including modeling primitives such as embedding bags and jagged tensors, optimized recommender system kernels powered by FBGEMM, a flexible sharder that supports a veriety of strategies for partitioning embedding tables, a planner that automatically generates optimized and performant sharding plans, support for GPU inference and common modeling modules for building recommender system models. TorchRec library is currently used to train large-scale recommender models at Meta. We will present how TorchRec helped Meta’s recommender system platform to transition from CPU asynchronous training to accelerator-based full-sync training.

  In einem sturmgebeutelten Militärflugzeug reist Seweryna Szmaglewska aus den Trümmern Warschaus nach Nürnberg, wo die Überlebende des Frauenlagers AuschwitzBirkenau am 27. Februar 1946 vor dem Internationalen Militärgerichtshof gegen die nationalsozialistischen Kriegsverbrecher aussagen wird. Sie ist eine von nur zwei Augenzeugen aus Polen, die vor dem Tribunal über das Erlittene sprechen dürfen. Im kriegszerstörten, vorfrühlingshaften Nürnberg fragt sich die junge Frau besorgt, wie sie den Albtraum der KZ-Realität in Worte fassen und der enormen Verantwortung gegenüber ihrem zerstörten Heimatland gerecht werden soll. Untergebracht im Grand Hotel, wo sich die amerikanischen Offiziere – und mit ihnen die Zeugen, Verteidiger und Korrespondenten aus aller Welt – abends amüsieren, wird sie von dunklen Erinnerungen verfolgt: Sie misstraut der deutschen Bevölkerung, staunt angesichts der Ungerührtheit der Angeklagten, und bei Görings theatralischem Auftritt vor dem Gericht schaudert ihr. Wird es für ihre Generation Gerechtigkeit und eine Zukunft geben? In »Die Unschuldigen in Nürnberg«, halb Erlebnisbericht, halb Roman, schildert die später zu literarischem Ruhm gelangte Schriftstellerin Seweryna Szmaglewska aus erster Hand eindringlich, präzise und in bisher ungekanntem Detail einen der wichtigsten Prozesse der Nachkriegszeit.

• Die Frauen von Birkenau Szmaglewska, Seweryna (2020). Schöffling & Co., Frankfurt am Main.

  In »Die Frauen von Birkenau« schildert Seweryna Szmaglewska ihre verstörenden Erlebnisse als politische Gefangene im Frauenlager von Auschwitz-Birkenau. Noch 1945, fast sofort nach ihrer Flucht im Januar, schrieb sie fieberhaft ihre Erinnerungen nieder, die ein wichtiges Zeugnis bei den Nürnberger Prozessen wurden. In einer ganz besonderen Erzählperspektive, ohne »ich« zu sagen, fängt sie darin nicht nur die Alltagswelt des Lagers ein, sondern auch berührende Einzelschicksale von Frauen aus ganz Europa. Da ist die Schauspielerin aus Wilna, die auch in der Baracke Texte deklamiert, da ist das Mädchen aus Thessaloniki mit seinen traurigen Liedern und da sind die Musikerinnen des Frauenorchesters. Wie mit einem Kameraauge zeichnet Seweryna Szmaglewska die desolate Verfassung der Gefangenen, die harte Arbeit und die Grausamkeiten der SS auf, aber sie beschwört auch den geistigen Austausch und den kulturellen Reichtum im Lager, mit dem die Frauen sich gegenseitig ermutigen und so ihre Würde zu wahren wissen. »Die Frauen von Birkenau« ist ein erschütterndes Buch und ein eindringliches Plädoyer für Menschlichkeit.
