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.}, language = {en} } @inproceedings{QuernerEwerlingKindsmueller2025, author = {Querner, Erich and Ewerling, Philipp and Kindsm{\"u}ller, Martin Christof}, title = {Touch gets it done, tangibles make it fun?

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.}, language = {en} } @book{Kraska, author = {Kraska, Martin}, title = {Technische Mechanik mit SMath Studio}, publisher = {Springer}, address = {Wiesbaden}, isbn = {978-3-658-50591-2}, doi = {10.1007/978-3-658-50592-9}, pages = {XI, 210}, abstract = {Dieses Lehrbuch f{\"u}hrt am Beispiel der Technischen Mechanik in die Nutzung der Mathematiksoftware SMath Studio f{\"u}r die Durchf{\"u}hrung und Dokumentation technischer Berechnungen ein.

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).

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.

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.

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.

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.

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.

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.}, language = {en} } @article{PilgermannVielhauerPetrovetal.2025, author = {Pilgermann, Michael and Vielhauer, Claus and Petrov, Denis and Dittmann, Jana and Kr{\"a}tzer, Christian}, title = {Attribution im IT-Grundschutz des BSI: Ausweitung der Detektion von Cyberangriffen im IT-Sicherheitsprozess}, series = {Datenschutz und Datensicherheit (DuD)}, volume = {49}, journal = {Datenschutz und Datensicherheit (DuD)}, number = {11}, publisher = {Springer}, doi = {10.1007/s11623-025-2173-5}, pages = {731 -- 736}, year = {2025}, abstract = {Inzwischen hat sich die Einsicht durchgesetzt, dass Cyberangriffe nicht komplett verhindert werden k{\"o}nnen.

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.

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.}, language = {en} } @article{Vollmer2025, author = {Vollmer, Michael}, title = {Nachtsicht ins All mit dem bloßen Auge: Sag mir, wie weit die Sterne steh'n}, series = {Physik in unserer Zeit}, volume = {2025}, journal = {Physik in unserer Zeit}, publisher = {Wiley}, doi = {10.1002/piuz.202501751}, pages = {2 -- 10}, year = {2025}, language = {de} } @misc{Hildebrandt2025, type = {Master Thesis}, author = {Hildebrandt, Hans}, title = {Integration von Cyber Threat Intelligence (CTI) in IT- und Medizinumgebungen: Quellen, Formate und praktische Umsetzung zur Verbesserung der IT-Sicherheit}, doi = {10.25933/opus4-3437}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-34377}, school = {Technische Hochschule Brandenburg}, pages = {131}, year = {2025}, abstract = {Die vorliegende Arbeit untersucht die Integration von Cyber Threat Intelligence in IT- und Gesundheitsumgebungen. Ziel war es, zu evaluieren, ob CTI-Daten in bestehende Sicherheitsl{\"o}sungen eingebunden werden k{\"o}nnen. 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. {\"U}ber einen Zeitraum von acht Wochen wurden Daten aus verschiedenen Open-Source-Feeds (u. a. CVE, MITRE, AlienVault, ThreatFox) gesammelt, verarbeitet und auf ihre Relevanz f{\"u}r den Gesundheitssektor gepr{\"u}ft. Zur Bewertung der Qualit{\"a}t der CTI-Daten wurde ein Beispielszenario f{\"u}r eine Krankenhausinfrastruktur entwickelt. Dieses Szenario umfasste typische Systeme und Hersteller im Gesundheitssektor, darunter Krankenhausinformationssysteme, Medizinger{\"a}te sowie Netzwerkinfrastrukturen. Die gesammelten Daten wurden auf diese Infrastruktur gemappt, um zu pr{\"u}fen, in welchem Umfang spezifische Bedrohungen abgedeckt werden. Die Ergebnisse zeigen, dass eine technische Integration grunds{\"a}tzlich m{\"o}glich ist und f{\"u}r generische IT-Bedrohungen belastbare Indikatoren vorliegen. Spezifische Informationen f{\"u}r den Gesundheitssektor konnten jedoch nur eingeschr{\"a}nkt identifiziert werden. Daraus ergibt sich, dass die Nutzung spezialisierter Feeds, etwa aus dem Health-ISAC, notwendig ist, um sektorspezifische Bedrohungen zuverl{\"a}ssig abdecken zu k{\"o}nnen.}, subject = {Computersicherheit}, language = {de} }
