With the recent developments in Large Language Models (LLMs), conversational language models are now available that enable natural language interaction in a VR environment. We evaluated four possible designs for LLM-based agents (푛 = 21) in an aircraft-engine training. Focusing on the primary questions when bringing LLM-based agents into VR: whether to use text or speech and whether to embody the conversational agent in 3D or not. Pre- and post-tests were used to measure retention and questionnaires were used to measure the User Experience (UX) of different design variants. Contrary to our hypotheses, retention was higher when using a non-embodied design compared to an embodied design. The output modality did not have a significant impact on the learning success, but it did have an impact on the UX.

Two major challenges accompany this trend. First, the training of surrogate models often requires a sufficient amount of data, the determination of which is inherently difficult. Second, these models often exhibit high complexity, limiting both the traceability of their outputs and the extraction of useful insights. Explainable Artificial Intelligence (XAI) methods have therefore emerged as promising tools to enhance the interpretability, explainability, and transparency of such models. In this work, a combination of the established Shapley Additive Explanations (SHAP) approach with a bootstrap-based method is investigated. The proposed framework provides insights into the contribution of individual features and enables an assessment of data sufficiency with respect to surrogate model performance. Building upon these findings, the Bootstrap-Informed Feature Importance (BIFI) method is proposed. BIFI offers a model-agnostic, robust identification of relevant features.The method is analyzed in the context of Design of Experiments (DOE) processes used for surrogate model construction. Evaluation on four synthetic datasets of increasing complexity, as well as a dataset from aero-engine development, demonstrates that BIFI-based DOEs can improve surrogate model quality measured in terms of R and MSE by up to 90%. Consequently, the proposed method enables more efficient utilization of simulations, computations, and experiments while reducing the required number of samples.

September 2025 N2 - This study compares Tangible User Interfaces (TUIs) with conventional touch interfaces (CTIs) on multi-touch tables for exploratory multi-user map applications. We developed a prototype that enables multiple users to interact with map content simultaneously and independently. Four interaction methods were implemented and evaluated: gesture-based touch control, widget-based touch joystick control, and two tangible interaction variants (a joystick and car-steering metaphor). A user study with 15 participants was conducted in which users navigated predefined routes with varying difficulty. We collected both objective performance measurements and subjective user assessments. While touch-based methods yielded higher accuracy in objective metrics, TUI-based interactions were rated significantly better by participants in terms of user experience. Notably, the car-steering tangible control was particularly well-received, highlighting how physical, playful interaction can enhance usability despite lower accuracy. These findings contribute to our understanding of how different interaction paradigms support collaborative exploration on multi-touch surfaces.

T1 - High-resolution in situ imaging reveals size-specific moonlight responses in zooplankton diel vertical migration JF - Scientific Reports N2 - Light is the primary cue driving zooplankton diel vertical migration (DVM), a strategy that balances predation risk with resource access. However, DVM is often oversimplified, with limited consideration of how light-driven risks and resource needs vary across taxa and life stages. This simplification is partly due to constraints on collecting high-resolution, size-resolved data —especially at night, when subtle shifts in illumination reshape nocturnal risk landscapes. To overcome these limitations, we deployed a high-resolution in situ modular Deep-focus Plankton Imager and an image-recognition approach to quantify fine scale DVM and body sizes of Cladocerans and Copepods in Lake Stechlin, Germany. Data was collected from day into night and across moonrise and was compared with environmental data from vertical profiling sondes. Typical DVM patterns emerged, with deeper daytime distributions, however, moonlight introduced additional behavioural complexity: larger individuals avoided illuminated layers, likely managing predation risk, while smaller individuals moved into these layers, possibly exploiting foraging opportunities and reduced risk. These light-mediated shifts were further shaped by ecological conditions; copepods tracked food-rich layers regardless of light levels at night, while cladocerans showed light-dependent responses to both temperature and food, such that light caused them to avoid otherwise favourable (warm, food-rich) layers. Our approach provides new insight into how zooplankton navigate nocturnal lightscapes, revealing size- and taxon-specific strategies. By establishing size-dependent responses to natural moonlight, this work provides a crucial baseline for predicting how artificial light at night may restructure zooplankton communities and destabilize freshwater food webs.

However, sensor systems work continuously, which results in constant energy consumption and data redundancy, especially for sensors with limited computing power and memory. In addition, installing and maintaining sensors in remote places creates additional challenges. An adaptive environmental sensing approach is developed to reduce data redundancy and energy consumption. A custom-designed sensor based on PIC16LF19156 microcontroller measures CO2, humidity and temperature simultaneously. The sensor is connected to a Raspberry Pi, where a signal processing algorithm is executed, aimed at reducing data redundancy, thereby increasing the energy efficiency of the system. The algorithm includes the discrete wavelet transform (DWT) to extract spectral features from the signals. A machine learning model trained on previous data estimates the daily variability of the signal and saves data labeled as SAVE (deviations) or SKIP (consistency). As a result, only the relevant intervals showing significant fluctuations are retained. The effectiveness of the proposed approach was evaluated by reconstructing the compressed signals and comparing them with the original data based on RMSE and MAE metrics, which confirms the insignificant loss of information.

JF - European Journal of Physics N2 - We discuss the farthest objects on Earth observable for the unaided, healthy naked eye during the daytime, i.e., the maximum visual range for observers on Earth. Visual range depends first on the properties of the material between observer and object and its interaction processes with radiation, but second also on our visual perception system. After a rough comparison of ranges in water, glass, and the atmosphere, we focus on the physical basis of visual range for the latter. As a contrast phenomenon, visual range refers to allowed light paths within the atmosphere. It results from the interplay of geometry, refraction, and light scattering. We present a concise overview of this field by qualitative descriptions and quantitative estimates as well as classroom demonstration experiments. The starting point is the common geometrical visual ranges, followed by extensions due to refraction and limitations due to contrast, which depend on scattering and absorption processes within the atmosphere. The quantitative discussion of scattering is very helpful to easily understand the huge ranges in nature from meters in dense fog to hundreds of kilometers in clear atmospheres. Extreme visual ranges from about 300 km to above 500 km require optimal atmospheric conditions, cleverly chosen locations and times, and a sophisticated topography analysis. Even longer visual ranges are possible when looking through the vertical atmosphere. From the ISS, daytime ranges well above 1000 km are possible.

JF - European Journal of Physics N2 - How far can we see with the naked eye at night? Many celestial objects like stars and galaxies as well as transient phenomena such as comets and supernovae can be observed in the night sky. We discuss the furthest distances of such objects and phenomena observable with the naked eye during the night-time for Earth-bound observers. The physics of night-time visual ranges differs from that of daytime observations because human vision shifts from cones to rods. In addition, mostly point sources are observed due to the large distances involved. Whether celestial objects and phenomena can be detected depends on the contrast of their radiation and the background sky luminance. We present a concise overview of how far we can see at night by first discussing the effects of the Earth's atmosphere. This includes attenuation of transmitted radiation as well as its role as a source of background radiation. Disregarding the attenuation of light due to interstellar and intergalactic dust, simple maximum night-time visual range estimates are based on the inverse square law, which can be easily verified by laboratory and demonstration experiments. From the respective calculations, we find that individual stars within the Milky Way galaxy of up to 15 000 light years are observable. Even further away are observable galaxies with several billion stars. The Andromeda galaxy can be observed with the naked eye at a distance of around 2.5 million light years. Similarly, the observability of supernovae also allows a visual range beyond the Milky Way galaxy. Finally, gamma ray bursts as the most energetic events in the universe are discussed concerning naked eye observations.

JF - Applied Optics N2 - Naked eye studies of the clear night sky reveal that a certain percentage of all observable stars can be perceived as having color. Subjective estimates differ widely, ranging from just a few to a maximum of above two hundred. Explanations are based on the emission spectra of the stars, which are modified by interstellar dust clouds, the Earth atmosphere, and mostly the inverse square law. Color changes occur not only for variation of the star’s angular elevation above the horizon, but as well for decreasing nighttime sky brightness due to the transition from photopic via mesopic to scotopic vision. The maximum number of stars showing color to the naked eye depends on star illuminances on Earth and the background sky luminance. The limit of observing color is found to correspond to apparent visual magnitudes around , defining the number of colored stars. This also means that naked eye perception of stars with color is only possible for a certain star distance range, which is well below the maximum naked eye visual range of stars.

T1 - Forces on a sphere suspended in flowing granulate JF - EPJ Web of Conferences N2 - We investigate the forces of flowing granular material on an obstacle. A sphere suspended in a discharging silo experiences both weight of the overlaying layers and drag of the surrounding moving grains. In experiments with frictional hard glass beads, the force on the obstacle was found to be practically flow-rate independent. In contrast, flow of nearly frictionless soft hydrogel spheres added drag forces which increased with the flow rate until reaching saturation at high flow speeds. The total force grew quadratically with the obstacle diameter in the soft, low friction material, while it grew much weaker, nearly linearly with the obstacle diameter, in the bed of hard, frictional glass spheres. In addition to the drag, obstacles embedded in the flowing hydrogel spheres experience a weight force from the top as if immersed in a hydrostatic pressure profile, but negligible counter-forces from below. In contrast, the frictional hard particles create a strong pressure gradient near the upper surface of the obstacle. Numerical simulations provide additional information that is difficult to access experimentally. They reproduce the experimental results and give hints for the origin of the different force contributions. The results have considerable practical importance for the discharge of storage containers with large objects suspended in flowing granular material.

T1 - Granular gases of rough spheres: Velocity, rotation and collision statistics from in-situ measurements, optical data and simulations JF - EPJ Web of Conferences N2 - Granular gases are not only of interest in fundamental physics, but they can also serve as a test ensembles for the validity of collision models employed in (loose) granular matter. The theoretical literature mainly addresses spheres under ideal conditions and simulations allow full access to all particle parameters, but experiments cannot fulfill these idealizations. We investigate granular gases of soft, rough spheres by combining microgravity experiments and adjusted simulations. We introduce Smart Particles with embedded autarkic micro-sensors for in-situ measurements of rotation rates and accelerations. Additionally, we extract 3D positions, translations and orientations of the particles from stereoscopic video data using Machine-Learning based algorithms. We address the partition of kinetic energy between the degrees of freedom, the angular and translational velocity as well as collision statistics. A simulation is adjusted to experiment parameters, showing good agreement of translational motion, but qualitative differences in the decay of rotational kinetic energy.

Such applications help users to retrieve and transact information through localized interaction points displayed on their (mobile) devices. Growing adoption of AR technology underlines the importance of incorporating suitable AR components for HBI, which is important for effective implementation and testing of HBI-AR use cases, increasing user satisfaction, and long-term viability. In this context, our short paper presents key experiences and lessons learned from an applied science project targeting the development and evaluation of an HBI-AR university campus app. Drawing on an ex-post inquiry of project collaborator experiences, we prescriptively highlight relevant AR solution requirements for this specific design context. Our findings amplify the importance of (1) balancing trade-offs between different spatial embedding computation methods, (2) modularity, customizability, and testability for efficient software development, and (3) taking building complexity and prototype maturity requirements into account when taking AR solution make-or-buy decisions. Our shared insights may inform future best practices and design principles for convergent HBI and AR projects in research and practice.

T1 - Machine learning for prediction of dynamical clustering in granular gases JF - EPJ Web of Conferences N2 - Continuously excited dense granular gases in microgravity can develop spatial inhomogeneities of the particle distribution. Dynamical clustering is a phenomenon where a significant share of particles concentrate in strongly overpopulated regions. It is caused by a complex interplay between the energy influx and dissipation in collisions. The overall packing fraction, container geometry, and excitation parameters influence the gas-cluster transition. We perform Discrete Element Method (DEM) simulations for frictional spheres in a cuboid container and apply statistical criteria to the packing fraction profiles. Machine learning (ML) methods are used to study the dependence of the gas-cluster transition on system parameters. It is a promising alternative to predict the state of the system without the need for the time-consuming DEM simulations. We identify the best models for predicting the dynamical clustering of frictional spheres in a specific experimental geometry.

At a sufficiently large overall packing fraction, a significant share of particles tend to concentrate in strongly overpopulated regions, so-called clusters, far from the excitation sources. This dynamical clustering is caused by a complex balance between energy influx and dissipation. The mean number density of particles, the geometry of the container, and the excitation strength influence cluster formation. A quantification of clustering thresholds is not trivial. We generate ‘synthetic’ data sets by Discrete Element Method simulations of frictional spheres in a cuboid container and apply established criteria to classify the local packing fraction profiles. Machine learning approaches that predict dynamic clustering from known system parameters on the basis of classical test criteria areoposed and tested. It avoids the necessity of complex numerical simulations.

T1 - AI-aided visual data analysis for granular gases: Complex particles, high density, and other challenges JF - EPJ Web of Conferences N2 - Microgravity experiments with three-dimensional (3D) granular gases, i.e., ensembles of freemoving macroscopic particles which collide inelastically, produce large amounts of stereo video footage which require processing and analysis. The main steps of data treatment are particle detection, 3D matching and tracking in stereoscopic views, and quantification of ensemble statistical properties such as, e.g. mean kinetic energy or collision processes. Frequent overlapping or clustering of particles and their complicated movement patterns require smart software solutions. In recent years, Artificial Intelligence/Machine Learning (AI/ML) methods were successfully used for analysis of granular systems. We have applied such techniques to the granular gases of rod-like particles and developed a software tool which enables a full cycle of semi-automatic experimental data analysis. The approach is now tested on more complex, non-convex particles, shaped as 3D crosses (hexapods). Another challenge is optical analysis of dense granular gases, where individual particles cannot be tracked. We present a preliminary result of application of an ML method for number density profiles extraction in VIP-Gran experiment with dense ensemble of rod-like particles.

They are relevant in the fields of cancer and in vitro metastasis or regenerative medicine (tissue engineering). Driven by the 3R concept—replacement, reduction, and refinement of animal testing—µg-exposure of human cells represents a new alternative method that avoids animal experiments entirely. New Approach Methodologies (NAMs) are used in biomedical research, pharmacology, toxicology, cancer research, radiotherapy, and translational regenerative medicine. Various types of human cells grow as 3D spheroids or organoids when exposed to µg-conditions provided by µg simulating instruments on Earth. Examples for such µg-simulators are the Rotating Wall Vessel, the Random Positioning Machine, and the 2D or 3D clinostat. This review summarizes the most recent literature focusing on µg-engineered tissues. We are discussing all reports examining different tumor cell types from breast, lung, thyroid, prostate, and gastrointestinal cancers. Moreover, we are focusing on µg-generated spheroids and organoids derived from healthy cells like chondrocytes, stem cells, bone cells, endothelial cells, and cardiovascular cells. The obtained data from NAMs and µg-experiments clearly imply that they can support translational medicine on Earth.

Die Untersuchung erfolgte anhand eines Kriterienkatalogs in einer containerisierten Testumgebung mit Integration in IBM QRadar. Die Ergebnisse zeigen, dass MISP durch hohe Interoperabilität und ressourcenschonenden Betrieb überzeugt, während OpenCTI ein semantisch tiefes, STIX-basiertes Datenmodell und erweiterte Analysefunktionen bietet. Beide Systeme ergänzen sich: MISP eignet sich für den operativen Informationsaustausch, OpenCTI für strategische und analytische Bedrohungsbewertung. Eine kombinierte Nutzung ermöglicht einen souveränen und skalierbaren CTI-Betrieb im behördlichen Umfeld.

Das System kombiniert das anomaliebasierte IDS Zeek mit dem signaturbasierten IDS Suricata und einem dazwischen geschalteten Python-Regelgenerator. Zeek analysiert aufgezeichneten Netzwerkverkehr aus dem Datensatz CIC-IDS2017 und schreibt Anomalien in Logdateien, aus denen der Regelgenerator automatisch Suricata-Regeln ableitet. Suricata nutzt diese Regeln zusätzlich zu ET Open, um wiederkehrende Angriffe schneller zu erkennen. Die Evaluation erfolgt offline auf PCAP-Dateien und vergleicht drei Konfigurationen: Zeek-Baseline, Suricata-Baseline (ET Open) und die hybride Variante. Bewertet wird anhand von Confusion-Matrixbasierten Metriken (u. a. Recall, Precision, F1-Score, False-PositiveRate). Die Ergebnisse zeigen, dass der hybride Ansatz die Erkennungsrate im Vergleich zu den Baselines deutlich erhöht und in mehreren Angriffsszenarien einen Recall nahe 1,0 erreicht. Gleichzeitig steigt jedoch die False-Positive-Rate erheblich an, insbesondere bei komplexem HTTP-Verkehr. Damit beantwortet die Arbeit die Forschungsfrage ambivalent: Die Kopplung von Zeek-Anomalien und automatischer SuricataRegelgenerierung ist technisch machbar und effektiv im Hinblick auf die Angriffserkennung, aber in der vorliegenden Form noch nicht für den produktiven Einsatz geeignet. Der entwickelte Prototyp dient als reproduzierbarer Referenzaufbau und zeigt klar, an welchen Stellen feinere Regelmodelle, Feedback-Mechanismen und realistischere Betriebsumgebungen notwendig sind.

Although many important common and rare genetic factors causing or contributing to these epilepsies have been identified in the past decades, many features of the genetic architecture are still insufficiently understood. This study integrates genome-wide association study (GWAS) data from the International League Against Epilepsy Consortium on Complex Epilepsies with transcriptome-wide association studies to identify genes whose genetically regulated expression levels are associated with epilepsy. Methods To achieve this, we used multiple computational approaches, including MAGMA, a tool for gene analysis of GWAS data, and its derivatives E-MAGMA and H-MAGMA, to improve gene mapping accuracy by utilizing tissue-specific expression and chromatin interaction data. Furthermore, we developed ME-MAGMA to incorporate methylation quantitative trait loci data, providing insights into epigenetic factors. Results We identified a total of 897 false discovery rate-corrected (<.05) candidates. These include voltage-gated calcium channels, voltage-gated potassium channels, and other genes such as NPRL2, CACNB2, and KCNT1 associated with epilepsy pathogenesis that act as key players in neuronal communication and signaling in the brain. Significance In this study, we propose new candidate genes to expand the dataset of potential epilepsy-causing genes. Further research on these genes may enhance our understanding of the complex regulatory mechanisms underlying GGE and other types of epilepsy, potentially revealing targets for therapeutic intervention.

Despite extensive work, the superconducting pairing symmetry in La3⁢Ni2⁢O7 remains unresolved, with conflicting results even for identical methods. We argue that different superconducting states in La3⁢Ni2⁢O7 are in close competition and highly sensitive to the choice of interaction parameters as well as pressure-induced changes in the electronic structure. Our study uses a multiorbital Hubbard model, incorporating all Ni 3⁢𝑑 and O 2⁢𝑝 states. We analyze the superconducting pairing mechanism of La3⁢Ni2⁢O7 within the random phase approximation and find a transition between 𝑑-wave and sign-changing 𝑠-wave pairing states as a function of pressure and interaction parameters, which is driven by spin fluctuations with different wave vectors. These spin fluctuations with incommensurate wave vectors cooperatively stabilize a superconducting order parameter with 𝑑𝑥2−𝑦2 symmetry for realistic model parameters. Simultaneously, their competition may be responsible for the absence of magnetic order in La3⁢Ni2⁢O7, demonstrating that magnetic frustration and superconducting pairing can arise from the same set of incommensurate spin fluctuations.

Unsere Welt ist im Wandel - technologisch, global, ökologisch. Selbst Handlungskonzepte wie das "grüne Wachstum" wirken zunehmend unsicher, vor allem auf einem Planeten mit begrenzten Ressourcen und wachsender Weltbevölkerung. Dieses Lehrbuch lädt dazu ein, neue Perspektiven zu gewinnen: Wie können sich Unternehmen und Standorte zukunftsfähig ausrichten? Und: Was müssen wir aus Sicht der Volkswirtschaftslehre - disziplinär und interdisziplinär - hierfür über komplex adaptive Systeme lernen? Das erforderliche Komplexitätsverständnis wird in drei Teilen Schritt für Schritt entwickelt und mit Blick auf die Nachhaltigkeit anwendungsbezogen veranschaulicht. Teil 1 bietet inspirierende Einblicke in die Vielfalt menschlicher Handlungsweisen, vom rationalen bis zum vielschichtigen Menschen, der sich von Narrativen, Emotionen und kognitiven Verzerrungen beeinflussen lässt. Teil 2 sieht den Menschen als Systemelement bzw. Akteur und beleuchtet systemische Wechselwirkungen bei zunehmendem Komplexitätsgrad. Die Vorstellungen von einem "guten Leben" wandeln sich, von materiellen Lebensstandards und sozialer Gerechtigkeit hin zu Krisenresilienz und transformativer Leistungsfähigkeit. Teil 3 stellt Ideen vor, wie die Governance menschengemachter Systeme mittels Regulierung, Kulturentwicklung und Nudging gelingen kann, wenn wir von der Partizipation in Wissens- und Lernnetzwerken und potenzieller Selbstwirksamkeit ausgehen. Das Buch bietet Impulse für Lehre, Forschung und Praxis. Es eignet sich nicht nur für Studierende und Lehrende der Volkswirtschaftslehre. Es eröffnet auch Lehrenden der Sekundarstufe und Erwachsenenbildung neue Sichten sowie denjenigen, die in Wirtschaft, Verbänden, Politik, Verwaltung oder in zivilgesellschaftlichen Organisationen beratend aktiv sind. Kurzum: Ein Buch für alle, die systemischen Wandel nicht nur verstehen, sondern mitgestalten wollen.

This case study demonstrates how the company leverages stores as strategic innovation hubs that extend far beyond their traditional sales function. The analysis highlights the role of store design, technological integration, and symbolic branding as key drivers of customer experience and brand equity. Flagship stores serve as a testing ground for testing new concepts, while local adaptations strengthen cultural relevance within communities. Findings suggest that in highly digital industries, physical retail remains strategically valuable – not as a relic of the past, but as a platform for differentiation, customer engagement, and innovation. Properly designed, physical stores complement digital channels and reinforce the overall brand experience. Y1 - 2025 VL - 71 IS - 4 PB - Deutsche Werbewissenschaftliche Gesellschaft e.V.

The workshop integrates principles from Education for Sustainable Development (ESD), transformative and experiential learning, participatory design, and critical reflection on the digital age to engage participants in critically examining the environmental, economic, and social impacts of digital technologies in the context of Sustainable Development Goals (SDGs). Structured in five modular phases, from self-reflection and knowledge activation to collaborative prototyping and peer evaluation, the workshop offers a hands-on, gamified learning experience centred on real-world sustainability challenges. Learners create user-centred paper-based prototypes for digital products using tactile materials, persona-driven scenarios and knowledge of sustainable product characteristics gained in the workshop. Outcome measurement is supported through pre- and post-workshop surveys, peer voting templates, and paper-based prototype artefacts, enabling rich insight into behavioural intentions and learning gains. The paper discusses the educational value and sustainability relevance of the workshop engaging young people in critically reflecting on the environmental, economic, and social consequences of digitalization. Finally, it highlights challenges and limitations and proposes directions for future research.

In Georgia, cervical cancer ranks as the fifth most common cancer among women, with approximately 330 new cases and 200 deaths reported annually. Despite the availability of effective HPV vaccines, national vaccination coverage remains low. This study aimed to evaluate HPV vaccination coverage, analyze cervical cancer incidence trends, and model the potential impact of increased vaccination uptake on cancer prevention outcomes in Georgia. Study design A retrospective observational study was conducted using national health registry data and modeling projections to assess the burden of cervical cancer and estimate the effect of scaled vaccination coverage. Methods National health databases were used to analyze HPV vaccination rates and cervical cancer incidence. Descriptive statistics, chi-square tests, and linear regression were applied to identify trends and disparities. Additionally, a dynamic transmission model was developed to simulate the 10-year impact of increasing HPV vaccination coverage on cervical cancer incidence. Results The crude cervical cancer incidence rate was 15.7 per 100,000 women, with an age-standardized rate of 10.6 per 100,000. In 2022, only 38 % of eligible girls aged 13–18 received the first HPV vaccine dose, and 26 % completed the second dose. Regional disparities in vaccination and screening were noted, and overall screening coverage declined to 13,890 women screened in 2022. Modeling showed that increasing vaccine coverage to 60 % could reduce cervical cancer incidence by 50 % (preventing ∼163 cases); coverage of 80 % and 90 % could reduce incidence by 70 % and 85 %, preventing 228 and 276 cases, respectively. Conclusion Low HPV vaccination uptake in Georgia (38 % first dose and 26 % dull coverage) and declining screening limit cervical cancer prevention. Modeling shows that increasing vaccination coverage to 60–90 % could prevent 163–276 cases over the next decade. Strengthening vaccination and screening strategies is essential to move forward elimination.

We conducted a controlled angling experiment, comprising 501 30-min experimental fishing trials in three meso- to eutrophic waterbodies and assessed catch rates and sizes of European perch (Perca fluviatilis) caught when offered two soft plastic lures (fluorescent vs. non-fluorescent) with similar reflective spectra. We also examined fluorescent properties of a range of market-available lures and modelled the experimental lure’s fluorescing effects under natural lake light. Considering the specific light environment of the study waters, the experimental fluorescent lure could get excited by downwelling visible daylight and fluoresce at depths of up to 3 meters. Based on a sample catch of 331 perch, and after controlling for interactions with illuminance, cloud cover, water depth and daytime, the fluorescence of the experimental lure did, however, neither affect the catch rate nor the size of perch caught. Lure fluorescence maybe less important than many anglers believe, but further studies in different lake conditions are needed.

This meta‐analysis investigates the effects of varying wavelengths and illuminance levels of ALAN on organisms. Broad‐spectrum ‘cool’ light, enriched with blue and ultraviolet radiation, strongly disrupts circadian rhythms, melatonin production and nocturnal activity. However, contrary to common assumptions, broad‐spectrum ‘warm’ light can be nearly as impactful as broad‐spectrum ‘cool’ light lacking ultraviolet radiation, despite the predominant influence of short wavelengths on physiological processes. The impact of ALAN is not consistently dose‐dependent, as even low light levels (< 5 lx) can cause substantial biological disruptions. Thus, effective mitigation strategies require tailored solutions to specific ecological contexts and should generally avoid nocturnal illumination unless clearly needed, as there is no single ‘safe dose’ and ‘safe spectrum’ of ALAN.

Ziel war es, zu evaluieren, ob CTI-Daten in bestehende Sicherheitslösungen eingebunden werden können. Außerdem sollte festgestellt werden, welchen Mehrwert die Daten im Hinblick auf die Erkennung und Abwehr von Bedrohungen bieten. Hierzu wurde eine Laborumgebung aufgebaut, bestehend aus OpenCTI zur Sammlung und Verwaltung von Bedrohungsinformationen, Logstash zur Datenweiterleitung sowie Wazuh zur Analyse und Alarmierung. Über einen Zeitraum von acht Wochen wurden Daten aus verschiedenen Open-Source-Feeds (u. a. CVE, MITRE, AlienVault, ThreatFox) gesammelt, verarbeitet und auf ihre Relevanz für den Gesundheitssektor geprüft. Zur Bewertung der Qualität der CTI-Daten wurde ein Beispielszenario für eine Krankenhausinfrastruktur entwickelt. Dieses Szenario umfasste typische Systeme und Hersteller im Gesundheitssektor, darunter Krankenhausinformationssysteme, Medizingeräte sowie Netzwerkinfrastrukturen. Die gesammelten Daten wurden auf diese Infrastruktur gemappt, um zu prüfen, in welchem Umfang spezifische Bedrohungen abgedeckt werden. Die Ergebnisse zeigen, dass eine technische Integration grundsätzlich möglich ist und für generische IT-Bedrohungen belastbare Indikatoren vorliegen. Spezifische Informationen für den Gesundheitssektor konnten jedoch nur eingeschränkt identifiziert werden. Daraus ergibt sich, dass die Nutzung spezialisierter Feeds, etwa aus dem Health-ISAC, notwendig ist, um sektorspezifische Bedrohungen zuverlässig abdecken zu können.
