TY - JOUR A1 - Rajan, Kohulan A1 - Weißenborn, Viktor A1 - Lederer, Laurin A1 - Steinbeck, Christoph A1 - Zielesny, Achim T1 - MARCUS: molecular annotation and recognition for curating unravelled structures JF - Digital Discovery N2 - The exponential growth of chemical literature necessitates the development of automated tools for extracting and curating molecular information from unstructured scientific publications into open-access chemical databases. Current optical chemical structure recognition (OCSR) and named entity recognition solutions operate in isolation, which limits their scalability for comprehensive literature curation. Here we present MARCUS (Molecular Annotation and Recognition for Curating Unravelled Structures), a tool designed for natural product literature curation that integrates COCONUT-aware schema mapping, CIP-based stereochemical validation, and human-in-the-loop structure refinement. This integrated web-based platform combines automated text annotation, multi-engine OCSR, and direct submission capabilities to the COCONUT database. MARCUS employs a fine-tuned GPT-4 model to extract chemical entities and utilises a Human-in-the-loop ensemble approach integrating DECIMER, MolNexTR, and MolScribe for structure recognition. The platform aims to streamline the data extraction workflow from PDF upload to database submission, significantly reducing curation time. MARCUS bridges the gap between unstructured chemical literature and machine-actionable databases, enabling FAIR data principles and facilitating AI-driven chemical discovery. Through open-source code, accessible models, and comprehensive documentation, the web application enhances accessibility and promotes community-driven development. This approach facilitates unrestricted use and encourages the collaborative advancement of automated chemical literature curation tools.

The scalability of the system is demonstrated by generalising the mechanical behaviour from the small geometry of the wing to a suitable scale for engineering applications, such as deployable structures for space applications. The tool is written in Python and based on the MuJoCo physics engine. Sections of the anal fan are modelled as a bar-and-hinge model with elastic tendons, allowing a high number of design parameters and fast computation. In light of these advantages, the wing folding and unfolding behaviour is investigated with respect to the tendon’s elastic properties and the actuation of the deformation. Bistability is characterised using a single tendon and the entire fan section. Given the upscaled geometry of the analysed section, the required tendon characteristics to transition between the stable states are identified within a reasonable range for technological transfer towards biomimetic structures modelled after the dermapteran hindwing.

However, optimizing the deposition characteristics, such as dimensional accuracy, surface quality, and layer uniformity, remains a key challenge, partly due to the complex dynamics of heat input and melt pool behavior. This study examines the influence of electron beam modulation on these deposition characteristics by systematically varying beam deflection parameters, including frequency and pattern, during the wire-based additive manufacturing of titanium. The effects of beam modulation on wire melting, melt pool stability, layer formation, and overall build geometry were thoroughly evaluated. The results demonstrate that carefully controlled electron beam modulation enables significant improvements in deposition stability, surface finish, and control over geometric features, thereby enhancing process reliability and enabling the production of near-net-shape titanium components. Notably, a parameter set consisting of a circular beam deflection at an oscillation frequency of 500Hz and an overfocus setting of + 40 mA effectively minimized surface ripples and waviness, thereby enhancing process stability and yielding defect-free components. These insights contribute to advancing DED-EB as a viable solution for applications where high geometric accuracy and process efficiency are demanded.

April 1-3, 2025, in Porto, Portugal N2 - As the student population becomes increasingly heterogeneous, providing effective feedback is crucial for personalized education. However, human feedback is resource-intensive, while large language models can be unreliable. Our method bridges this gap by offering informative, similarity-based feedback on mathematical inputs. In an experiment with 207 students, we found that this approach encourages engagement, facilitates the completion of harder exercises, and reduces quitting after incorrect inputs. Compared to traditional feedback mechanisms that struggle with unforeseen error patterns, our method increases student perseverance and confidence. By balancing reliability, resources, and robustness, our solution meets the diverse needs of contemporary students. With its potential to enhance self-learning and student outcomes, this research contributes to the growing conversation on personalized education and adaptive learning systems.

May 2-4, 2024, in Angers, France N2 - The relevance of e-learning for higher education has resulted in a wide variety of online self-learning materials over the last decade like pedagogical agents (PA) or learning games. Regardless of this variety, educators wonder whether they can make use of these tools for their goals and if so, which tool to choose and in which context a specific tool performs best. To do so, the collection and analysis of learning data – referred to as Learning Analytics (LA) – is required. Along with digital learning environments the possibilities of applying LA are growing. Often, LA focuses on data that can easily be quantified: drop-out quota, time or grade performance. To facilitate learning in a more procedural sense, a deeper understanding of learners’ behavior in specific contexts with specific exercise designs is desired. This study therefore focuses on usage patterns. Learners’ movements through three different designs of mathematical exercises – (i) plain exercises, (ii) PA supported and (iii) fantasy game design – are analyzed with Markov chains. The results of an experiment with 503 students inform about which design facilitates what kind of learning. While the PA design lets learners enter more partial solutions, the fantasy game design facilitates exercise repetition.

May 21-24 2025, Prague, Czech Republic N2 - Servant leadership is widely recognized for its positive effects on followers, but its impact on leaders' mental health remains understudied. This gap is crucial, as servant leadership might place significant demands on leaders' psychological resources, without sufficient social, psychological, or organizational rewards. Drawing on the Conservation of Resources Theory (COR), we investigate how and when servant leadership affects leaders' mental health, viewing its role not only as resource-depleting but also as resource-generating for leaders, depending on the organizational context. Two cross-sectional studies were conducted using leader self-assessments (N = 101; N = 170). Study 1 focused on the relationship between servant leadership, experienced meaningfulness, emotional exhaustion, and flourishing, emphasizing the resource-generating potential of servant leadership. Study 2, examined the moderating effect of the distributive justice climate (DJC) on the link between servant leadership and emotional exhaustion, exploring the possibility of resource depletion under conditions of low organizational fairness. Results. In Study 1, servant leadership was found to mitigate emotional exhaustion by enhancing experienced meaningfulness at work. Moreover, it fostered leaders' flourishing through the same mechanism, suggesting that servant leadership can be a source of leaders’ well-being. Study 2 demonstrated that DJC moderates the servant leadership–emotional exhaustion relationship. Specifically, when DJC is low, servant leaders are more susceptible to emotional exhaustion, indicating that unfair organizational climates can exacerbate the resource-depleting aspects of servant leadership. Servant leadership has the potential to both reduce and exacerbate emotional exhaustion in leaders. While it generates psychological resources like experienced meaningfulness, which enhances well-being, its effectiveness is influenced by the organizational context. In unjust environments, servant leadership's emotional demands may lead to resource depletion. These findings are in line with COR and highlight the complex impact of servant leadership on the well-being of leaders. Limitations remain to issues of causality.

This paper addresses this gap by conducting an integrative literature review (ILR) of Brush et al.’s (2009) 5 M framework article and proposes a conceptualization of 5 M framework research alongside future research directions for the field of women’s entrepreneurship. Design/methodology/approach – Our study utilizes an ILR to analyze how researchers have leveraged the 5 M framework and what this reveals about its development and role in women’s entrepreneurship research. We draw on Scopus and Google Scholar databases to present a comprehensive review of all publications (n 5 944) that cite Brush et al.’s (2009) article (from 2009 to 2023), focusing on those works (n 5 87) which base their methodological or theoretical approach on the 5 M framework. Findings – Our ILR reveals that research using the 5 M framework can be conceptualized as consisting of four different layers: the specific contributions made by such research to the development of the 5 M framework itself; the key themes and mechanisms within women’s entrepreneurship addressed by this research; the methodological approaches applied; and the empirical contexts in which the framework dimensions have been employed. Research limitations/implications – Our study identifies pertinent literature gapsin women’s entrepreneurship and provides pathways for diversifying theory-building in the field. Originality/value – We analyze a prominent theoretical framework in the field of women’s entrepreneurship. Our analysis shows not only pathways for future women’s entrepreneurship research but also the status of the field and how researchers deal with existing frameworks, thus highlighting opportunities to go beyond the status quo.

Principles, Perspectives and Potential (Part of the book series: CSR, Sustainability, Ethics & Governance ((CSEG)) N2 - Sustainability communication as an increasingly circumscribable research field grounds in communication, management and marketing concepts. This chapter focuses on communication of sustainability, sustainable consumption and green claiming and discusses the effects of non-transparent sustainability communication and greenwashing. It specifically presents a study on how the suspicion of greenwashing in green advertising affects attitudes towards the ad and the brand, as well as the purchase intention. The affect transfer hypothesis is used as a model to understand advertising effects in this context. Additionally, this study delves into potential influencing factors on suspicion of greenwashing, such as the type of green advertising and the “lifestyle of health and sustainability” (LOHAS). The research question is addressed through a quantitative experimental online survey. The results demonstrate that the suspicion of greenwashing has a negative effect on attitude towards the ad and on attitude towards the brand, as well as on purchase intention. The chapter therefore offers new insights into one of the critical aspects of strategic sustainable communication and lays the groundwork for future research on “washing” (green, pink, rainbow, etc.) and the need for re-framing sustainability in business-consumer discourses.

We argue that two elements are pivotal to bypass this problem. First, genuine partnership with patients—ranging from biospecimen donation to agenda setting—can unlock critical resources and align research with real-world needs. Second, molecular intersections between HHT and related pathologies call for coordinated, cross-disease programmes rather than isolated efforts. Recent multi-stakeholder gatherings hosted by patient organisations in Germany and elsewhere, such as the Second Scientific Symposium by the German HHT self-help group (Morbus Osler Selbsthilfe e.V.) in May 2025, have shown that when clinicians, basic scientists from different disciplines, and affected families co-design research questions, novel in vitro models can be generated more accurately, and pragmatic clinical trials emerge. Here, we outline actual opportunities for patient-integrated cellular model systems, shared biobanking, and comparative approaches across vascular malformation syndromes. In our opinion, letting informed and well-organised patient communities assemble such meetings opens unique opportunities twofold: on the one hand, the field can finally break out of its disease-specific silos; on the other hand, the development of novel HHT therapies could be accelerated by learning from progress in related pathologies.

Phishing simulations via email are a widespread tool used to measure user awareness, especially in workplace settings. However, current studies focusing on large-scale analysis of phishing simulations often have issues: The phishing simulations were conducted using a small sample size (mostly one or two organizations), or while many emails are sent, the analysis focuses only on specific companies. This study analyzes phishing simulations conducted over three years at 36 organizations with over 68 000 delivered emails. We compare different dimensions of the organizations where these simulations were conducted, such as the economic sector and departments. Furthermore, we evaluate various dimensions of phishing simulation campaigns, such as detection difficulty and the scenario under which the simulation occurs. Our findings indicate significant disparities in the results, such as the industry sector in which the company operates. Moreover, we find substantial differences between the success rates of varying scenarios used for phishing emails.

Conference Proceedings N2 - Hybrid broadcast broadband television (HbbTV) is an evolving technology that connects linear TV with modern HTML5 applications, delivering extras like games, videos, and online shopping. However, its bidirectional transmission functionality raises privacy concerns, as it introduces new tracking methods for TV channels. While previous studies focused on security issues or user awareness of HbbTV privacy challenges, a detailed examination of the tracking and transparency mechanisms of the HbbTV ecosystem is still missing. This study fills this gap by extensively analyzing these features within the European HbbTV ecosystem, and in particular within German-language TV channels. We monitored more than 350 TV channels for over 400 hours, evaluating 1) prevalent HbbTV tracking methods, 2) consent notice prevalence and user interactions, and 3) privacy policy disclosures. Our findings indicate that the HbbTV tracking system operates independently of the Web, consent notices exploit system constraints to influence users, and privacy policies often do not align with actual data practices.

How higher fungi respond to dsRNA is not known. We demonstrate that Magnaporthe oryzae (Mo), a globally significant crop pathogen, internalizes dsRNA across a broad size range of 21 to about 3000 bp. Incubation of fungal conidia with 10 ng/μL dsRNA, regardless of size or sequence, induced aberrant germ tube elongation, revealing a strong sequence-unspecific effect of dsRNA in this fungus. Accordingly, the synthetic dsRNA analogue poly(I:C) and dsRNA of various sizes and sequences elicited canonical fungal stress pathways, including nuclear accumulation of the stress marker mitogen-activated protein kinase Hog1p and production of ROS. Leaf application of dsRNA to the cereal model species Brachypodium distachyon suppressed the progression of leaf blast disease. Notably, the sequence-unspecific effect of dsRNA depends on higher doses, while pure sequence-specific effects were observed at low concentrations of dsRNA ( < 0.03 ng/μL). The protective effects of dsRNA were further enhanced by maintaining a gap of at least seven days between dsRNA application and inoculation, and by stabilising the dsRNA in alginate-chitosan nanoparticles. Overall, our study opens up additional possibilities for the development and use of dsRNA pesticides in agriculture.

T1 - Solute excretion improves trehalose uptake and desiccation tolerance of Metarhizium brunneum blastospores JF - Biotechnology for the Environment N2 - In this study, a novel approach was developed to increase the intracellular trehalose concentration in M. brunneum blastospores by uptake from the medium, improving their desiccation tolerance. Briefly, placing the blastospores in a hypotonic environment induced solute excretion, allowing significantly increased trehalose uptake during subsequent trehalose treatment. Conductivity changes and GC–MS analysis revealed that glycerol and lactate excretion is triggered in a hypotonic NaCl solution. After hypotonic + trehalose treatment, intracellular glycerol, lactate, and glucose levels increased, while other desiccation‑protective solutes remained unaffected. A fluorescence‑based single‑cell analysis of membrane stress and death during osmotic desiccation and rehydration showed that membrane stress and cell death were strongly amplified upon rehydration. Trehalose treatment reduced this amplification, while hypotonic + trehalose treatment minimised cell death and prevented a stress response during rehydration, though it increased membrane stress during desiccation. Newly formed germ tubes were identified as critical points of membrane failure during desiccation. Ultimately, the drying survival of blastospores was significantly improved by the hypotonic + trehalose treatment compared to untreated or trehalose‑only‑treated blastospores. In summary, this technique successfully enhanced blastospore desiccation tolerance and could be adapted to load cells with other solutes.

T1 - Interpolyelectrolyte complexes of in vivo produced dsRNA with chitosan and alginate for enhanced plant protection against tobacco mosaic virus JF - International Journal of Biological Macromolecules N2 - We developed a formulation of long double-stranded RNA (dsRNA) using interpolyelectrolyte complexes (IPECs) composed of the biopolymers chitosan and alginate, in order to protect the dsRNA from biotic and abiotic factors. Our primary objectives were to enhance stability of dsRNA against environmental nucleases and, secondarily, to mitigate the negative charge of the dsRNA, which may promote foliar uptake. Our approach relies on submicron particles with adjustable surface charge being either positive or negative. Following this approach, we obtained a high encapsulation efficiency of 94 %. Subsequently, we investigated the influence of the charge ratio and total polymer content on the size, size distribution and ζ-potential of the IPECs. We discovered that formulating at low polymer concentrations ≤0.05 g/L with charge ratios of ≤0.9 (+/􀀀 ) and ≥ 1.25 (+/􀀀 ), respectively, produced <100 nm particles. Furthermore, the IPEC formulation protected dsRNA from enzymatic degradation by RNase III and micrococcal nuclease. In addition, we observed outstanding protection of formulated dsRNA from heat degradation. Experiments on Nicotiana benthamiana plants showed that formulated dsRNA offered protection against tobacco mosaic virus. In essence, this formulation demonstrates versatility for the production of IPECs with customizable size, surface charge, and nucleic acid content.

In alignment with this policy, Germany aims to perceived carbon neutrality by 2045, with the electrification of transport playing a central role. Corporate fleets are particularly well-suited for electrification due to their relatively short ownership cycles and frequent vehicle renewals. However, the pace of adoption in organizations remains slow. The success of such technological transitions depends largely on acceptance at the decision-making level. This study investigates the determinants of organizational decision-makers’ behavioral intention to electrify their corporate fleets prior to implementation. To this end, the newly developed Acceptance Model for Electrification (eAM) integrates the two-stage innovation decision-making process within companies. The model accounts for 60% of the variance in behavioral intention. Drawing on the findings, this paper proposes practical recommendations for policy development.

Studying innovation as a social context structured by power, we focus on 18 women innovators in innovation-driving environments. While these women appear to symbolize gender equality and embody contemporary postfeminist ideals of individualism, choice, and empowerment, many have simultaneously experienced (in)visibility and navigated unequal power structures throughout their careers. We investigate how these (in)visibility experiences are reconciled with the promises of postfeminism, exploring how postfeminist ideals are interpreted and negotiated by them to make sense of their own (in)visibility. While (in)visibility has traditionally been theorized in relation to norms and gendered power structures, our findings reveal how postfeminist discourses reframe visibility as an individualized, moralized imperative rooted in self-responsibility. Through this lens, we identify four postfeminist sense-making approaches: meritocratic visibility (embodying postfeminist ideologies), retraditionalized visibility (conforming to femininity), self-disciplined visibility (adapting to gender inequality), and collective-oriented visibility (challenging the status quo). These sense-making approaches highlight the various ways in which postfeminist sensibilities shape subjective experiences, often masking structural inequalities and allowing these to persist in contexts that claim to promote equal opportunities, such as the innovation environment. We point to the need for collective rather than individualized action for structural transformation.

Conference Proceedings N2 - This paper introduces Shaalke, a novel analytical software tool developed for the high-accuracy evaluation of long-term photovoltaic module measurement data. Addressing the critical need for robust parameter extraction from field data, Shaalke integrates advanced filtering, linear regression, and algorithmic processing to overcome limitations of traditional evaluation methods. We demonstrate Shaalke's capability to accurately determine STC parameters and both static and dynamic temperature coefficients, showing excellent agreement with manufacturer specifications and independent laboratory measurements. A key finding is Shaalke's precise mapping of the irradiance dependence of module efficiency, filling a significant gap left by typical datasheet values which often only provide data at 1000 and 200 W/m². Furthermore, the tool enables reliable power degradation analysis, identifying modules that exceed manufacturer-tolerated limits. Shaalke provides a comprehensive, data-driven platform for understanding real-world module performance, offering invaluable insights for system design, operation, and quality assurance, thereby bridging the gap between laboratory specifications and field performance.

To increase its efficacy and provide a reliable surface treatment technique, it is necessary to optimize process parameters, enhance material adhesion, and guarantee high-quality, reliable coatings. These measures help to extend the lifespan of components. In this study, the surfaces of AISI 904L stainless steel samples were cladded to prepare various Co-based composite coatings with single and multiple layers reinforced with WC–CoCr–Ni powder. The phases within the newly developed layers were investigated using X-ray Diffraction (XRD), while the microstructure was examined using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX). Further tests were performed to assess the hardness, wear resistance and corrosion performance of the deposited coatings. Analyzing and comparing the coatings, it was observed that the coating performance increased with increasing thickness and generally due to a lower amount of Fe present within the microstructure.

This paper reframes power as a constitutive, and not incidental, dimension of ecosystem functioning. Integrating insights from Pfeffer's resource-dependence theory with Foucault's and Bourdieu's social perspectives, we develop a Power-Sensitive Entrepreneurial Ecosystem Framework (PSEEF) that conceptualises power across micro (entrepreneurial identity), meso (network structures), and macro (institutional governance) levels. Our key insight is that power dynamics are the hidden mechanisms through which EEs determine who gains visibility and support, and whose ventures remain peripheral. Recognising these mechanisms enables scholars and practitioners to understand ecosystems not merely as collections of resources but as evolving arenas of legitimacy and control. The framework provides actionable tools for ecosystem leaders to diagnose and rebalance inequalities, advancing both the analytical and practical agenda for inclusive and high-performing EEs.

Through two case studies in Germany's Ruhr area, the article demonstrates how a strong sense of belonging enhances resilience, trust and social capital, essential for business success. The experiences of two MEs, Ilyas and Elif, illustrate belongingness as a catalyst for connectedness and embeddedness, enabling access to networks and resources while countering discrimination. The study suggests that policy frameworks should acknowledge and support the emotional and relational aspects of MEs' integration in EEs. Emphasising informal support systems, community engagement and tailored interventions could help overcome structural barriers and foster more inclusive ecosystems. Future research should further examine these dynamics across diverse cultural and geographical contexts to offer a more comprehensive understanding of MEs' entrepreneurial trajectories.

Eine bionische Lösung zur passiven Luftregelung T2 - 11. Bionik-Kongress (24.-25.10.2025) in Bremen N2 - Die Zukunft automobiler Mobilität ist überwiegend elektrisch. Im Vergleich zu bestehenden Systemen ändern sich die Anforderungen an die Teilsysteme. Ein Luftstrom zur Kühlung von Komponenten wird nun vorwiegend benötigt, wenn das Auto steht (d. h. beim Laden) oder bei langsamen Geschwindigkeiten unter Volllast. Bisher werden in solchen Fällen aktiv angetriebene Lüfter verwendet, die Energie verbrauchen und Geräusche emittieren. Wir schlagen zur Komplexitätsreduktion ein passives adaptives System vor, das eine konvektionsgetriebene Kühlung ermöglicht. Das entwickelte System ist ein hoch adaptives Flachventil, das vom Hoftüpfel abgeleitet ist. Es wurde durch einen iterativen Designprozess entwickelt, der sowohl strukturelle als auch thermodynamische Simulationen einschloss. In Harthölzern und Koniferen ermöglichen Hoftüpfel den anspruchsvollen Transport vertikaler Flüssigkeiten, indem sie Schäden lokal begrenzen. Abhängig von der Struktur können sie sich bei plötzlichen Druckänderungen schließen und die Funktion von Ventilen übernehmen. Das Ergebnis des bionischen Entwicklungsprozesses ist ein flaches Ventil, das kostengünstig zu produzieren, langlebig, leicht, wartungsfrei und geräuschlos ist. Es ermöglicht das passive Umschalten der Luftstromerzeugung am Wärmetauscher der Kühlung zwischen natürlicher Konvektion oder einem aktiven Luftstrom, ohne dass komplexe Mess- und Steuersysteme erforderlich sind. Die geometrischen und materiellen Gestaltungsfaktoren ermöglichen eine einfache Anpassung des Ventils an die gewünschten Umschaltbedingungen während des Designprozesses. Hierfür wurden Festigkeitsprüfungen mit unterschiedlichen Materialien und Geometrien durchgeführt. Die auf dessen Basis erstellte Faustformel ist für Entwickelnde ein Hilfestellung, um ohne Finite-Elemente-Analysen die Geometrie und Materialien des Ventils auslegen zu können.

T1 - Padding Matters - Exploring Function Detection in PE Files: Data/Toolset T2 - CODASPY '25: Proceedings of the Fifteenth ACM Conference on Data and Application Security and Privacy, June 4-6 2025, Pittsburgh PA USA N2 - Function detection is a well-known problem in binary analysis. While prior work has focused on Linux/ELF, Windows/PE binaries have only partially been considered. This paper introduces FuncPEval, a dataset for Windows x86 and x64 PE files, featuring Chromium and the Conti ransomware, along with ground truth data for 1,092,820 function starts. Utilizing FuncPEval, we evaluate five heuristics-based (Ghidra, IDA, Nucleus, rev.ng, SMDA) and three machine-learning-based (DeepDi, RNN, XDA) function start detection tools. Among these, IDA achieves the highest F1-score (98.44%) for Chromium x64, while DeepDi closely follows (97%) but stands out as the fastest. Towards explainability, we examine the impact of padding between functions on the detection results, finding all tested tools, except rev.ng, are susceptible to randomized padding. The randomized padding significantly diminishes the effectiveness of the RNN, XDA, and Nucleus. Among the learning-based tools, DeepDi exhibits the least sensitivity, while Nucleus is the most adversely affected among the non-learning-based tools.

T1 - EPT Switching vs. Instruction Repair vs. Instruction Emulation: A Performance Comparison of Hyper-Breakpoint Variants JF - Eng N2 - Virtual Machine Introspection (VMI) is a powerful technology used to detect and analyze malicious software inside Virtual Machines (VMs) from the outside. Asynchronous access to the VM’s memory can be insufficient for efficient monitoring of what is happening inside of a VM. Active VMI introduces breakpoints to intercept VM execution at relevant points. Especially for frequently visited breakpoints, and even more so for production systems, it is crucial to keep performance overhead as low as possible. In this paper, we present an empirical study that compares the performance of four VMI breakpoint-implementation variants—EPT switching (SLAT view switching) with and without fast single-stepping acceleration, instruction repair, and instruction emulation—from two VMI applications (DRAKVUF, SmartVMI) with the XEN hypervisor on 20 Intel Core i processors ranging from the fourth to the thirteenth generation. Instruction emulation was the fastest method across all 20 tested platforms. Modern processors such as the Intel Core i7 12700H and Intel Core i9 13900HX achieved median breakpoint-processing times as low as 15 µs for the emulation mechanism. The slowest method was instruction repair, followed by EPT switching and EPT switching with FSS. The order was the same for all measurements, indicating that this is a strong and generalizable result.

Hierfür wird zunächst eine erste wissenschaftliche Definition des Begriffs Dark LLM erstellt. Anschließend werden relevante Dark LLMs vorgestellt, auf deren Gefahren aufmerksam gemacht und geeignete Gegenmaßnahmen erörtert. Danach erfolgt eine rechtliche Einordnung anhand mehrerer Gesetzestexte. Dann wird eine prototypische Entwicklung eines LLMs durchgeführt, welches für OSINT-Recherchen eingesetzt werden kann. Die rechtliche Analyse und die technische Implementierung ergeben, dass der Einsatz eines Dark LLMs in der polizeilichen Arbeit unzulässig ist. Zudem wird ein polizeiliches LLM nach der KI-Verordnung sowohl als Hochrisiko-KI-System als auch als KI-Modell mit allgemeinem Verwendungszweck eingestuft, wodurch sich etliche Pflichten ergeben, die ein LLM in ihrer Funktion einschränken. Trotz dieser Einschränkungen ist ein Einsatz eines solchen LLMs sinnvoll, denn dieses kann viele OSINT-Informationen sekundenschnell zu einer gebündelten Antwort zusammenfassen, was die polizeiliche Arbeit erheblich erleichtert. Durch allgemeines OSINT-Training und die Anbindung weiterer OSINT-Quellen kann die Qualität der Antwort deutlich verbessert werden. N2 - This paper analyses the use of dark LLMs to conduct OSINT research in the context of police hazard prevention and law enforcement in North Rhine-Westphalia. To this end, an initial scientific definition of the term dark LLM is first established. Subsequently, relevant dark LLMs are presented, their dangers are highlighted, and appropriate countermeasures are discussed. This is followed by a legal classification based on several legal texts. Then a prototype LLM is developed that can be used for OSINT research. The legal analysis and technical implementation show that the use of a dark LLM in police work is not permitted. In addition, according to the AI Regulation, a police LLM is classified as both a high-risk AI system and an AI model for general use, which results in a number of obligations that restrict the function of an LLM. Despite these restrictions, the use of such an LLM is useful because it can summarise a lot of OSINT information into a bundled response in a matter of seconds, which makes police work considerably easier. Through general OSINT training and the connection of additional OSINT sources, the quality of the response can be significantly improved.

Veröffentlichung zur 28. Fachtagung der Gesellschaft für angewandte Wirtschaftspsychologie (GWPS), Hochschule Hamm-Lippstadt 13.-15. Februar 2025 N2 - Theoretical Background: Work-Life Blending refers to the dissolution and permeability of boundaries between work and personal life, leading to an integrated experience across these domains. Despite its growing prevalence, a comprehensive conceptualisation of Work-Life-Blending is lacking. Our study addresses this gap by conducting a systematic review to define and clarify the construct, guided by Clark’s (2000) work/family border theory. Research Question: Our study aimed to identify key factors and dimensions of Work-Life Blending, leading to a holistic conceptualisation. Specifically, our review seeks to answer: What are the key factors and dimensions of Work-Life-Blending, and how can they be integrated into a unified concept and definition? We aim to review the current state of knowledge, define and clarify the concept, and propose a future research agenda. Methodology: Following PRISMA guidelines (Liberati et al., 2009; Moher et al., 2009), we analysed 51 relevant articles from an initial pool of 1,400 references. A systematic review approach was used to synthesise existing literature and identify the main factors and dimensions associated with Work-Life Blending. Findings: Our findings revealed a diverse and multifaceted field, structured using Clark’s (2000) key concepts. This framework provided deeper insights into the complex nature of the topic, highlighting significant diversification in the studies. Discussion and Implications: The study provides a strong foundation for further research on Work-Life Blending. By establishing a classification of key determinants, we offer a comprehensive framework for future studies, e.g., to explore which lifestyle principles can enhance work-life integration and address the challenges of modern work arrangements.

N2 - Diese systematische Übersichtsarbeit bewertet die Wirksamkeit von Mentalem Imaginationstraining (engl. Mental Imagery Training, MIT) zur Leistungssteigerung und Stressbewältigung für Hochrisikoberufe wie Polizeibeamten und Feuerwehrleuten. MIT, eine kognitive Technik zur mentalen Visualisierung von Aufgaben und Einsatzszenarien, wird auf ihr Potenzial hin untersucht, psychomotorische Fähigkeiten zu verbessern und stressbedingte Gesundheitsprobleme in extrem anspruchsvollen Einsatzfeldern zu reduzieren. Mit dem Job Demands-Resources (JD-R) Modell als theoretischem Rahmen untersucht die Arbeit, wie MIT als Ressource zur Minderung der schädlichen Effekte hoher beruflicher Anforderungen beitragen kann, indem sie berufsbezogene und persönliche Ressourcen stärkt. Eine umfassende Literatursuche gemäß den PRISMA-Richtlinien identifizierte zehn relevante Studien. Diese Studien belegen, dass MIT signifikant zur Stressreduktion, zur Erhöhung der Resilienz und zur Verbesserung der Aufgabenbewältigung in komplexen und fehleranfälligen Einsatzsituationen beitragen kann. Insbesondere zeigt MIT Potenzial für einen prophylaktischen Ansatz zur Prävention stressbedingter Gesundheitsprobleme sowie zur Steigerung der operativen Effizienz. Trotz dieser positiven Befunde sind weitere Forschungen notwendig, um die spezifischen Effekte von MIT im Vergleich zu anderen Stressbewältigungsmaßnahmen zu isolieren und die optimale Umsetzung in Trainingsprogrammen für Hochrisikoberufe zu fördern. Die Ergebnisse deuten auf praktische Anwendungen von MIT in strukturierten Trainingsumgebungen hin, um das Wohlbefinden und die Leistung in stressintensiven Berufen nachhaltig zu verbessern.

Lecture Notes in Computer Science (LNCS), vol 16072 N2 - In this work, we present a comparative analysis of SMILES, DeepSMILES, and SELFIES string representations for chemical struc-tures in neural machine translation tasks in cheminformatics. Using transformer-based models, we systematically evaluated their effective-ness in translating between these representations and the correspond-ing linguistic IUPAC nomenclature. The experimental results demon-strate comparable performance for all three string representations, with SMILES achieving a marginally higher accuracy (99.30% with stereo-chemical information, 99.21% without) compared to its alternatives. In scaling experiments with 1, 10, and 50 million compounds, the perfor-mance differences remained small, though the performance gap narrowed with larger datasets. These findings suggest that researchers can con-fidently continue using SMILES for neural machine translation tasks with transformers, which benefits from their extensive support in exist-ing chemical libraries, tools, and databases, rather than adopting newer representations. This work has a significant impact on developing more efficient chemical language models in drug discovery, material science, and chemical database curation.

Current optical chemical structure recognition (OCSR) and named entity recognition solutions operate in isolation, which limits their scalability for comprehensive literature curation. Here we present MARCUS (Molecular Annotation and Recognition for Curating Unravelled Structures), a tool to aid curators in performing literature curation in the field of natural products. This integrated web-based platform combines automated text annotation, multi-engine OCSR, and direct submission capabilities to the COCONUT database. MARCUS employs a fine-tuned GPT-4 model to extract chemical entities and utilises an ensemble approach integrating DECIMER, MolNexTR, and MolScribe for structure recognition. The platform aims to streamline the data extraction workflow from PDF upload to database submission, significantly reducing curation time. MARCUS bridges the gap between unstructured chemical literature and machine-actionable databases, enabling FAIR data principles and facilitating AI-driven chemical discovery. Through open-source code, accessible models, and comprehensive documentation, the web application enhances accessibility and promotes community-driven development. This approach facilitates unrestricted use and encourages the collaborative advancement of automated chemical literature curation tools. We dedicate MARCUS to Dr Marcus Ennis, the longest-serving curator of the ChEBI database, on the occasion of his 75th birthday.

However, creating Mo-rich deposits is challenging, as the codeposition process typically favors Ni. Optimal deposition conditions for Mo-rich NiMo catalysts remain insufficiently explored. This article investigates Mo-rich NiMo electrodeposition from an ammonia-free citrate bath using NaSO4 as a chlorine-free support electrolyte. The effects of the deposition parameters, 1) sodium molybdate concentration in the electrolyte, 2) deposition current density, and 3) enhanced mass transport via working electrode rotation on the alkaline HER activity, were studied. The electrodeposits, containing 44–66 wt% Mo, exhibited increased surface area due to a rough, cracked morphology and variable oxygen content of the catalyst. The oxygen content was linked to HER activity, revealing an inhibiting effect. The lowest overpotential of 118 mV at −10  mA cm−2 for the alkaline HER was achieved using an electrolyte with 0.02 mol L−1 sodium molybdate, a deposition current density of 600 mA cm−2, without electrode rotation. Respective samples combined a favorable Ni:Mo ratio comprising 56 wt% Mo content with increased surface area and low oxygen content.

PySSA enables the creation and sharing of workflow projects that comprise defined protein 3D structure predictions from their amino acid sequence, protein 3D structure alignments, as well as their visual analysis with distance diagrams or hotspot inspection. All operations can be conveniently performed by scientists without specialized computer skills or even programming knowledge on their local Windows computers, without the need for powerful GPU hardware. Thus, PySSA can help make protein structure prediction more accessible for end-users in scientific research areas like protein chemistry or molecular biology. In addition, the application is well-suited for educational purposes due to its user-friendliness and low learning curve. PySSA is openly available on GitHub, alongside a convenient installer executable for the Windows operating system: https://urban233.github.io/PySSA/install.html. To demonstrate its capabilities, the usage of PySSA in a protein mutation study on the protein drug Bone Morphogenetic Protein 2 (BMP2) is described: the structure prediction results indicate that the previously reported BMP2-2Hep-7M mutant, which is intended to be less prone to aggregation, does not exhibit significant spatial rearrangements of amino acid residues interacting with the receptor.

Open Access Series in Informatics (OASIcs) N2 - Mixed Reality (MR) is a technology with strong potential for advancing research in Human-Robot Interaction (HRI) for space exploration. Apart from the efficiency and high flexibility MR can offer, we argue that its benefits for HRI research in space contexts lies particularly in its ability to aid human-in-the-loop development, offer realistic hybrid simulations, and foster broader participation in HRI research in the space exploration context. However, we believe that this is only plausible if MR-based simulations can yield comparable results to fully physical approaches in human-centred studies. In this position paper, we highlight several arguments in favour of MR as a tool for space HRI research, while emphasising the importance of the open question regarding its scientific validity. We believe MR could become a central tool for preparing for future human-robotic space exploration missions and significantly diversify research in this domain.

To isolate the influence of printing speed, all other parameters were kept constant, and two filament variants—natural (unpigmented) and black PLA—were analyzed. ISO 527-2 type 1A specimens were produced and tested for dimensional deviations and ultimate tensile strength (UTS). The results indicate that printing speed has a marked impact on both geometric precision and mechanical performance. The optimal speed of 300 mm/s provided the best compromise between dimensional accuracy and tensile strength for both filaments. At speeds below 300 mm/s, under-extrusion caused weak layer bonding and air gaps, while speeds above 300 mm/s led to over-extrusion and structural defects due to thermal stress and rapid cooling. Black PLA yielded better dimensional accuracy at higher speeds, with cross-sectional deviations between 2.76% and 5.33%, while natural PLA showed larger deviations of up to 8.63%. However, natural PLA exhibited superior tensile strength, reaching up to 46.59 MPa, with black PLA showing up to 13.16% lower UTS values. The findings emphasize the importance of speed tuning and material selection for achieving high-quality, reliable, and efficient FDM prints.

T1 - Complex compositional and metabolic response of river sediment microbiomes to multiple anthropogenic stressors JF - ISME Communications N2 - Rivers face constant anthropogenic stress, resulting in significant changes in microbial community composition. What remains unclear is whether stream microbiomes exhibit distinct resilience patterns in composition and/or activity upon exposure to different stressors. By subjecting 64 river-connected mesocosms to multiple stressors, we show that sediment microbiomes of small lowland rivers are highly sensitive to low flow velocity. This stress results in altered community compositions incapable of mitigating the applied stressor within a two-week timeframe despite functional stability (inferred via metagenomics). Transcriptomics revealed a systematic heat shock response in the community and a highly active, metabolically versatile, uncharacterized anaerobic keystone species. Increases in temperature (+ 3.5°C) or salinity (+ 0.5 mS/cm) elicited minor responses at community and transcriptomic levels (e.g., upregulation of photosystems). Following a two-week recovery, transcriptomic-inferred stress responses vanished completely, underscoring the river microbiome resilience. Given the complex community responses observed at the activity and compositional levels, we conclude that maintaining natural river flow is vital to preventing energy loss and reduced microbiome activity in river sediments.

While the ecological effects of TWW on microbial diversity have been studied, understanding the functional responses of protist communities remains limited. This study employs metatranscriptomics to unravel the temporal dynamics of protist community functions in response to TWW exposure. Using mesocosm experiment, water samples were analyzed over a ten-day period to monitor shifts in metabolic pathways and community interactions. Our results indicate that processed metatranscriptomic data, focusing on treatment-significant pathways, is more sensitive than traditional methods, such as meta-barcoding, and non-target screening, in detecting wastewater-induced perturbations. Early exposure to TWW significantly altered expression of pathways associated with signal transduction and environmental interaction, while general metabolic pathways showed resilience. Over time, the protist community showed signs of adaptation with expression levels stabilizing towards the end of the experiment. This study underscores the importance of focussing on functional shifts rather than just taxonomic changes for assessing wastewater impacts on freshwater ecosystems. Our findings advocate for the use of metatranscriptomics as a robust indicator for TWW detection, aiding in development of targeted environmental management strategies.

T1 - Integrative Analysis of Nontargeted LC-HRMS and High-Throughput Metabarcoding Data for Aquatic Environmental Studies Using Combined Multivariate Statistical Approaches JF - Analytical Chemistry N2 - Significant progress in high-throughput analytical techniques has paved the way for novel approaches to integrating data sets from different compartments. This study leverages nontarget screening (NTS) via liquid chromatography-high-resolution mass spectrometry (LC-HRMS), a crucial technique for analyzing organic micropollutants and their transformation products, in combination with biological indicators. We propose a combined multivariate data processing framework that integrates LC-HRMS-based NTS data with other high-throughput data sets, exemplified here by 18S V9 rRNA and full-length 16S rRNA gene metabarcoding data sets. The power of data fusion is demonstrated by systematically evaluating the impact of treated wastewater (TWW) over time on an aquatic ecosystem through a controlled mesocosm experiment. Highly compressed NTS data were compiled through the implementation of the region of interest-multivariate curve resolution-alternating least-squares (MCR-ALS) method, known as ROIMCR. By integrating ANOVA-simultaneous component analysis with structural learning and integrative decomposition (SLIDE), the innovative SLIDE-ASCA approach enables the decomposition of global and partial common, as well as distinct variation sources arising from experimental factors and their possible interactions. SLIDE-ASCA results indicate that temporal variability explains a much larger portion of the variance (74.6%) than the treatment effect, with both contributing to global shared space variation (41%). Design structure benefits include enhanced interpretability, improved detection of key features, and a more accurate representation of complex interactions between chemical and biological data. This approach offers a greater understanding of the natural and wastewater-influenced temporal patterns for each data source, as well as reveals associations between chemical and biological markers in an exemplified perturbed aquatic ecosystem.

Bacteria and fungi play a crucial role in this process by breaking down coarse particulate organic matter (CPOM), such as leaf litter, into nutrients available for other organisms. However, the specific contribution of bacteria and their functional interactions with fungi in freshwater sediments have yet to be thoroughly explored. In the following study, we enriched organic matter through the addition of alder (Alnus glutinosa) leaves into artificial stream channels (AquaFlow mesocosms). We then investigated enzyme expression, metabolic pathways, and community composition of fungi and bacteria involved in the degradation of CPOM through metatranscriptomics and amplicon sequencing. Enzymes involved in the degradation of lignin, cellulose, and hemicellulose were selectively upregulated with increased organic matter. Analysis of ITS and 16S rRNA gene sequences revealed that during decomposition, fungal communities were predominantly composed of Basidiomycota and Ascomycota, while bacterial communities were largely dominated by Pseudomonadota and Bacteroidota. The similar gene expression patterns of CPOM degradation related enzymes observed between bacteria and fungi indicate potential functional interaction between these microbial groups. This correlation in enzyme expression may indicate that bacteria and fungi are jointly involved in the breakdown of coarse particulate organic matter, potentially through mutualistic interaction. This study uncovers the specific enzymatic activities of bacteria and fungi and the importance of microbial interactions in organic matter decomposition, revealing their central role in facilitating nutrient cycling and maintaining the ecological health and stability of freshwater ecosystems.

Conventional steels frequently do not provide sufficient protection against wear and corrosion. One solution is to coat these components using methods like thermal spraying to apply cermet coatings such as Cr3C2-NiCr or WC-Co-Cr. In light of increasingly strict environmental regulations, more eco-friendly alternatives are needed, especially ones that use little or no Cr, Ni, Co, or W. Another alternative is the recycling of powder materials, which is the focus of this research project. This study investigated whether filter dust from an HVOF system could be used to develop a new coating suitable for use in applications requiring resistance to wear and corrosion. This is challenging as the filter dusts have heterogeneous compositions and irregular particle sizes. Nevertheless, this recycled material, referred to as “Green Cermets” (GCs), offers previously untapped potential that may also be of ecological interest. An established WC-Co-Cr coating served as a reference. In addition to friction wear and corrosion resistance, the study also examined particle size distribution, hardness, microstructure, and susceptibility to crack formation at the interface and inside the coating. Even though the results revealed a diminished performance of the GC coatings relative to the conventional WC-CoCr, they may still be applicable in various industrial applications.

In this study, a CoCrFeNiCu-based high-entropy alloy, distinguished from conventional CoCrFeNi systems by the addition of Cu, which is known to enhance toughness and wear resistance, was investigated to better understand the effects of compositional modification on processability and performance. The influence of key process parameters, specifically laser power and scan speed, on the processability of CoCrFeNiCu-based high-entropy alloys produced by laser powder bed fusion additive manufacturing was investigated, with a focus of low laser power, which is critical for minimizing defects and improving the resulting microstructure and mechanical performance. The printed sample density gradually increases with higher volumetric energy density, achieving densities exceeding 99.0%. However, at higher energy densities, the samples exhibit susceptibility to hot cracking, an issue that cannot be mitigated by adjusting the process parameters. Mechanical properties under optimized parameters were further evaluated using Charpy impact and (in situ) tensile tests. These evaluations were supplemented by in situ tensile experiments conducted within a scanning electron microscope to gain insights into the behavior of defects, such as hot cracks, during tensile testing. Despite the sensitivity to hot cracking, the samples exhibited a respectable ultimate tensile strength of 662 MPa, comparable to fine-grained steels like S500MC (070XLK). These findings underscore the potential of CoCrFeNiCu-based high-entropy alloys for advanced applications. However, they also highlight the necessity for developing strategies to ensure stable and reliable processing methods that can mitigate the susceptibility to hot cracking.

An evaluation was conducted to ascertain the influence of the formulation process and the presence of the insert on the mechanical behavior with regard to tensile strength. The aluminum matrix was obtained from commercial and scrap alloys, elaborated by advanced methods of degassing and chemical modification. Meanwhile, the steel mesh reinforcement was cleaned, copper plated, and preheated to optimize wetting and, consequently, adhesion. The structural characterization was performed by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy analyses (EDX), which highlighted a well-defined interface and uniform copper distribution. The composite was produced by means of horizontal-axis centrifugal casting in a fiberglass mold, followed by cold rolling to obtain flat specimens. A total of eight tensile specimens were examined, with measured ultimate tensile strengths ranging from 78.5 to 119.8 (MPa). A thorough examination of the fractured specimens revealed a brittle fracture mechanism, devoid of substantial plastic deformation. The onset of failures was frequently observed at the interface between the aluminum matrix and the steel mesh. The use of SEM and EDX investigations led to the confirmation of the uniformity of the copper coating and the absence of significant porosity or interfacial defects. A bimodal distribution of tensile strength values was observed, a phenomenon that is likely attributable to variations in mesh positioning and local differences in solidification. A correlation was established between the experimental results and an analytical polynomial model, thereby confirming a reasonable fit. In sum, the present study provides a substantial foundation for the development of metal matrix composites with enhanced performance, specifically designed for challenging structural applications. This method also demonstrates potential for recycling aluminum scrap into high-performance composites with controlled microstructure and mechanical integrity.

This paper presents the outcomes of an international course, “3D Prosthetics and Orthotics”, offered to undergraduate students in the Biomimetic program at Westfälische Hochschule (Germany), in collaboration with the 3D Orthotics and Prosthetics Laboratory at the Federal University of São Paulo—UNIFESP (Brazil). The course combined theoretical and hands-on modules covering digital modeling (CAD), simulation (CAE), and fabrication (CAM), enabling students to develop bioinspired assistive devices through a Project-based learning approach. Working in interdisciplinary teams, students addressed real-world rehabilitation challenges by translating biological mechanisms into engineered solutions using additive manufacturing. Resulting prototypes included a hand prosthesis based on the Fin Ray effect, a modular finger prosthesis inspired by tendon–muscle antagonism, and a cervical orthosis designed based on stingray morphology. Each device was digitally modeled, mechanically analyzed, and physically fabricated using open-source and low-cost methods. This initiative illustrates how biomimetic mechanisms and design can be integrated into education to generate functional outcomes and socially impactful health technologies.

A novel tuned-beam sensing device is developed to measure low-amplitude activity-induced cage vibrations. The sensing device uses a mechanical beam structure to enhance a six-axis IMU that increases the signal-to-noise ratio (SNR) by 20 to 40 times in a relevant environment. A sophisticated classification algorithm is developed to process vibration sequences with a variable time frame that utilizes multi-level discrete wavelet transformation (MLDWT) to extract time–frequency features and optimize signal properties. The extracted features are classified by a convolutional neural network–long short-term memory (CNN-LSTM) machine learning model to determine the activity class. The ground truth is obtained with a camera-based system using EthoVision XT from Noldus and a custom post-processor. The method is developed on a dataset containing 300 h of vibration measurements with camera-based reference and includes two separate home cages and two individual mice. The method classifies the activity types Resting, Stationary Activity, Walking, Activity in Feeder, and Drinking with an accuracy of 86.81% and an average F1 score of 0.798 using a 9 s time frame. In long-term monitoring, the proposed method reproduces behavioral patterns such as sleep and acclimatization as accurately as the reference method, enabling home cage monitoring in the husbandry environment with a low-cost sensor.

However, current state-of-the-art ammonia monitoring systems are labor-intensive and expensive. Metal Oxide Semiconductor (MOS) sensors offer a promising alternative due to their compatibility with sensor networks, enabling high-resolution ammonia monitoring across spatial and temporal scales. While MOS sensors exhibit high sensitivity to various volatile compounds, temperature-cycled operation is commonly employed to enhance selectivity, effectively creating virtual sensor arrays. This study aims to improve ammonia detection by designing a virtual sensor array through a cyclic data-driven approach, integrating machine learning with solid-state sensor modeling. The results of a two-week dataset with measurements of four different pig barns demonstrate ammonia sensing with a sampling rate of about 2/min and a range of 1–30 ppm. The method is robust and exhibits a 10% increase in normalized RMSE when comparing testing results of an unseen sensor module with results of the training dataset. A filter membrane boosts accuracy and prevents data loss due to contamination, such as flyspecks. Overall, the used MOS sensor BME688 is effective and economical for widespread continuous ammonia monitoring and localization of ammonia sources in pig barns.

Ziel dieses Prozesses ist herauszufinden, welche Form und Topologie eine Struktur besitzen muss, um die an sie gestellte Konstruktionsaufgabe besonders gut zu erfüllen. Damit die optimierten Strukturen auch herstellbar sind, ist das Bestreben aktueller Forschung, Informationen über die Fertigungsprozesse direkt in die entsprechenden Optimierungsverfahren in Form von Fertigungsrestriktionen zu integrieren. In dieser Arbeit wird eine Methodik zur Integration von Fertigungsrestriktionen bei 3D-Fräsverfahren in die Topologieoptimierung mit der Level-Set-Methode entwickelt. Berücksichtigt werden dabei die Gewährleistung der Werkzeugzugänglichkeit aller Bearbeitungspunkte sowie die Einhaltung einer Mindestwandstärke. Die Methodik basiert auf der Induktion eines Strukturwachstums in Bereichen, die entweder unzugänglich oder zu dünn sind. Um diese Bereiche zu identifizieren, wird ein Verfahren entwickelt, bei dem die Level-Set-Funktion entlang der Außenkonturen realistischer Werkzeuggeometrien interpoliert wird. Zur Induktion des Strukturwachstums wird regelmäßig ein Potential definiert. Dieses besitzt innerhalb der Struktur größere Werte als außerhalb und ändert sich normal zum Strukturrand linear. Eine Minimierung des auf dem Strukturrand vorliegenden Potentials wird in ein Strukturwachstum überführt. Dazu werden die Sensitivitäten des Potentials bezüglich Verschiebungen des Strukturrandes ermittelt und mit den Entwicklungsgeschwindigkeiten der Level-Set-Funktion gekoppelt. Dadurch werden beide Fertigungsrestriktionen in eine gemeinsame mathematische Restriktion überführt und schließlich explizit in das Optimierungsproblem integriert.

This is especially true for the relationships between nutrients and bacteria, as phosphorus, nitrogen and organic carbon availability are known to influence bacterial population dynamics. It has been suggested that low nutrient conditions prompt the evolutionary process of genome streamlining. This process helps conserve scarce nutrients and allows for proliferation. Genome streamlining is associated with genomic properties such as %GC content, genes encoding sigma factors, percent coding regions, gene redundancy, and functional shifts in processes like cell motility and ATP binding cassette transporters, among others. The current study aims to unveil the impact of nutrition on the genome size, %GC content, and functional properties of pelagic freshwater bacteria. We do this at finer taxonomic resolutions for many metagenomically characterized communities. Our study confirms the interplay of trophic level and genomic properties. It also highlights that different nutrient types, particularly phosphorus and nitrogen, impact these properties differently. We observed a covariation of functional traits with genome size. Larger genomes exhibit enriched pathways for motility, environmental interaction, and regulatory genes. ABC transporter genes reflect the availability of nutrients in the environment, with small genomes presumably relying more on metabolites from other organisms. We also discuss the distinct strategies different phyla adopt to adapt to oligotrophic environments. The findings contribute to our understanding of genomic adaptations within complex microbial communities.

T1 - Assessing the response of an urban stream ecosystem to salinization under different flow regimes JF - Science of The Total Environment N2 - Abstract Urban streams are exposed to a variety of anthropogenic stressors. Freshwater salinization is a key stressor in these ecosystems that is predicted to be further exacerbated by climate change, which causes simultaneous changes in flow parameters, potentially resulting in non-additive effects on aquatic ecosystems. However, the effects of salinization and flow velocity on urban streams are still poorly understood as multiple-stressor experiments are often conducted at pristine rather than urban sites. Therefore, we conducted a mesocosm experiment at the Boye River, a recently restored stream located in a highly urbanized area in Western Germany, and applied recurrent pulses of salinity along a gradient (NaCl, 9 h daily of +0 to +2.5 mS/cm) in combination with normal and reduced current velocities (20 cm/s vs. 10 cm/s). Using a comprehensive assessment across multiple organism groups (macroinvertebrates, eukaryotic algae, fungi, parasites) and ecosystem functions (primary production, organic-matter decomposition), we show that flow velocity reduction has a pervasive impact, causing community shifts for almost all assessed organism groups (except fungi) and inhibiting organic-matter decomposition. Salinization affected only dynamic components of community assembly by enhancing invertebrate emigration via drift and reducing fungal reproduction. We caution that the comparatively small impact of salt in our study can be due to legacy effects from past salt pollution by coal mining activities >30 years ago. Nevertheless, our results suggest that urban stream management should prioritize the continuity of a minimum discharge to maintain ecosystem integrity. Our study exemplifies a holistic approach for the assessment of multiple-stressor impacts on streams, which is needed to inform the establishment of a salinity threshold above which mitigation actions must be taken.

Such technologies can offer great opportunities for children with long-term illnesses to continue attending school. Consequently, telepresence robots are already used in some schools when children are absent for long periods. However, despite their positive impact, such robots also create challenges for the privacy of people involved in such a setting. Therefore, in this paper, we discuss the user needs of such robots in this specific and privacy-sensitive application field. We held three workshops with different user groups with and without experience with the robots. Among them were formerly and currently ill children, parents, teachers, head teachers, media educators, and supporting personnel. We discussed their experiences (if any), ideas, expectations, and concerns with a focus on privacy aspects to find out about the user needs of different user groups. Our results reveal various interrelationships and conflicts between the individual actors. They serve as a basis to discuss the implications for the design of future telepresence robots for schoolchildren.

Autonomous behavior is usually realized by using AI models built with real-world data, which often reflect existing inequalities and prejudices in society. Even if designers do not intend it, there are risks that robots will be developed that discriminate against certain users, e. g. based on gender. In this work, we investigate the implications of a gender-biased robot that disadvantages women, which unfortunately is a bias in AI that is often reported. Our experiment shows that both men and women perceive the gender-biased robot to be unfair. However, our work indicates that women are more aware that a gender bias causes this unfairness. We also show that gender bias results in the robot being perceived differently. While the gender bias resulted in lower likability and intelligence ratings by women, men seem to lose trust in the robot if it behaves unfairly.

Consequently, they are already used if children are absent for long periods. When designing such systems, the privacy of various stakeholders must be considered. However, conflicts often arise because the privacy requirements of different user groups cannot be fulfilled simultaneously. In this paper, we analyze the corresponding trade-offs that have to be made when designing telepresence robots under conflicting privacy requirements. We analyzed previous literature and held three workshops with different user groups (children, parents, teachers, head teachers, media educators, and supporting personnel) with and without experience with telepresence robots in schools. Based on the literature and the workshop results, we present four major privacy trade-offs we identified and discuss design approaches for them. With this work, we contribute to the design research on telepresence robots in schools by revealing the major privacy-related conflicts and potential design approaches to overcome the conflicts.

However, they are often time-consuming to create and difficult to access during work. This paper introduces an approach that simplifies the creation of video tutorials in the workplace and promotes their use during work. By utilizing smart glasses, practitioners can record video tutorials during their daily work processes and utilize them for knowledge transfer to other employees without much additional effort. This offers the advantage of directly and easily sharing expertise in the workplace without being constrained by time or location. Given the intended simplicity of this approach, the question arises whether it creates video tutorials that help people in their learning. The paper presents a study that compares the effectiveness of knowledge transfer using these video tutorials against traditional personal training methods in the workplace. With 18 participants from the nursing and production sectors, we observed the training and learning outcomes of using video tutorials on smart glasses over multiple sessions, comparing them with personal training, which is considered the standard for practical onboarding. The study results indicate that learning with video tutorials does not significantly differ in terms of learning outcomes from traditional personal training methods. Overall, this study highlights the potential of video tutorials with smart glasses for knowledge transfer in workplaces, while also identifying challenges and opportunities for optimizing onboarding processes for employees.

These robots enable a new form of human-robot interaction in which contact is possible. There are two robot-related factors that play a decisive role in the interaction dynamics and human perception in such a case - the motion speed and distance the robot keeps away from the human. Literature indicates that these factors influence whether humans perceive trust, safety, and comfort, which are essential components in the acceptance of robots by their end users. However, although speed and distance were intensively investigated in isolation, little is known about their combined effect. To this end, we conducted an experiment investigating the impact of the industrial robot arm’s approaching speed and stopping distance on the users’ trust, safety, and comfort while they were performing a collaborative task. Our results provide interesting insights into the implications of speed and trust. While we were able to replicate former studies in terms of implications of speed and distance, our data does not show any interaction effect between the two variables. However, our participants’ observations indicated that distance impacts the dependent variables more severely than speed.

In hybrid teams of humans and robots, trust enables smooth collaboration and reduces risks. Just as collaboration between humans and robots differs from interpersonal collaboration, so does the nature of trust in human-robot interaction (HRI). Therefore, further investigations on trust formation and dissolution in HRI, factors affecting it, and means for keeping trust on an appropriate level are needed. However, our knowledge of interpersonal trust and trust in autonomous agents cannot be transferred directly to HRI. In this paper, we present a study with 32 participants on trust formation and dissolution as well as forecasting to influence trust in an industry robot. Results show differences in dynamics and factors of trust formation and dissolution. Additionally, we find that the effect of forecasting on trust depends on task success. These findings support the design of trustful human-robot interaction and corresponding robotic team members.

On the basis of environmental sensitivity theory (Pluess & Boniwell, 2015) as well as the job characteristics model (Hackman & Oldham, 1976), we investigated the moderating impact of SPS (HSP Scale; Aron & Aron, 1997; Konrad & Herzberg, 2019) on the relationship between job characteristics (Work Design Questionnaire; Morgeson & Humphrey, 2006; Stegmann et al., 2010) and organizational citizenship behavior (OCB Scale; Podsakoff et al., 1990). The results of our two-wave survey study with 199 employees from a broad range of industries and students indicate that SPS strengthens the relationship between feedback as well as task significance and OCB, but SPS weakens the relationship between autonomy (work methods) as well as task variety and OCB. N2 - Wie Hochsensibilität die Auswirkungen von Arbeitsmerkmalen auf das Verhalten von Mitarbeitenden beeinflusst Zusammenfassung: Hochsensibilität bzw. Sensory processing sensitivity (HPS bzw. SPS) ist ein Persönlichkeitsmerkmal, welches sich durch eine besonders ausgeprägte Empfindsamkeit für sensorische Reize auszeichnet (Aron & Aron, 1997). Basierend auf der Environmental Sensitivity Theory (Pluess & Boniwell, 2015) und dem Job-Characteristics Model (Hackman & Oldham, 1976), untersuchen wir den moderierenden Einfluss von Hochsensibilität (HSP-Skala, Aron & Aron, 1997; Konrad & Herzberg, 2019) auf die Beziehung zwischen Aufgabenmerkmalen (WDQ, Morgeson & Humphrey, 2006, Stegmann et al., 2010) und OCB (OCB-Skala, Podsakoff et al., 1990). Die Ergebnisse unserer zweiwelligen schriftlichen Befragung an N = 199 deutschen Angestellten verschiedener Branchen und Studierenden deuten darauf hin, dass die Ausprägung der Hochsensibilität eines Mitarbeitenden die Auswirkungen von Autonomie, Feedback, Aufgabenvielfalt und Bedeutsamkeit der Aufgabe auf OCB moderiert. Hochsensiblere Mitarbeitende steigern durch Feedback und die Bedeutsamkeit ihrer Tätigkeit ihr extraproduktives Verhalten noch stärker als weniger sensible Mitarbeitende, während die Gestaltungsmerkmale Autonomie und Aufgabenvielfalt ihr extraproduktives Verhalten abschwächen.

Das Ziel der vorliegenden Studie ist daher die Validierung einer deutschen Übersetzung der AMS in zwei Studien. Die Übersetzung der AMS folgte dem TRAPD-Modell, einer Weiterentwicklung der Back-Translation-Methode. Die erste zweiwellige Studie (N = 211) zeigte gute bis sehr gute interne Konsistenzen und mit den Originalversionen der AMS weitgehend übereinstimmende Retest-Reliabilitäten. Die postulierte siebenfaktorielle Struktur wies gegenüber einem ein- bzw. dreifaktoriellen Modell den besten Modell-Fit auf. Die zweite zweiwellige Studie (N = 221) analysierte die konvergente und divergente Validität, sowie die Kriteriumsvalidität. Zusammenfassend verfügt die deutsche Version der AMS über gute psychometrische Eigenschaften und kann daher in Forschung und Praxis eingesetzt werden. N2 - There is presently no validated German translation of the Academic Motivation Scale (AMS). This study therefore validates the German translation of the AMS in two studies. The translation of the AMS followed the TRAPD model, a further development of the back-translation method. The first two-wave study (N = 211) showed good to very good internal consistencies and retest reliabilities that were largely consistent with the original versions of the AMS. The postulated seven-factor structure showed the best model fit compared to a one-or-three-factor model. The second two-wave study (N = 221) analyzed convergent and divergent validities as well as criterion validity. In summary, the German version of the AMS has good psychometric properties and can be used in research and practice.

Fachtagung der Gesellschaft für angewandte Wirtschaftspsychologie (GAWPS), 13.-15. Februar 2025, Hamm N2 - In der öffentlichen Debatte wird die Generation Z häufig als zentrale Herausforderung für die zukünftige Arbeitswelt dargestellt. Es wird behauptet, dass diese Generation, geprägt durch digitale und gesellschaftliche Umbrüche, andere Erwartungen an Arbeitgeber hat als ihre Vorgänger. Unsere Studie untersucht, ob diese Annahme wissenschaftlich haltbar ist und ob sich die Relevanz von Arbeitgeberattraktivitätsfaktoren zwischen den Generationen Baby Boomer, Generation X, Y und Z signifikant unterscheidet. Basierend auf einem neuen empirischen Ansatz analysieren wir mit einer umfangreichen deutschen Stichprobe (N=1133) mittels multipler Regressionen die Vorhersagekraft von 19 Arbeitgeberattraktivitätsfaktoren für die allgemeine Arbeitgeberattraktivität. Dabei prüfen wir, ob und inwieweit die Generationszugehörigkeit moderierende Effekte auf die Bedeutung dieser Faktoren hat. Die Ergebnisse zeigen, dass wesentliche Attraktivitätsfaktoren wie Identifikation mit dem Unternehmen, Management und Führung sowie die Arbeitsaufgabe generationsübergreifend relevant sind. Unterschiede zeigen sich lediglich in einzelnen Dimensionen wie Arbeitsplatzsicherheit, Corporate Social Responsibility, Work-Life-Balance und Unternehmensimage, wobei die Varianzaufklärung durch Generationsunterschiede äußerst gering ist (<2 %) und die signifikanten Regressionskoeffizienten im Durchschnitt nur bei .23 liegen. Die Studie liefert eine empirische Basis für die Diskussion über Generationsunterschiede bei arbeitsrelevanten Einstellungen. Unsere Ergebnisse stellen die gängige Praxis von generationsspezifischem Employer Branding und eine Überschätzung von Generationsunterschieden, die auf stereotypen Annahmen beruhen, infrage. Selbst Alters- und Lebensphaseneffekte lassen sich in unseren Ergebnissen kaum nachweisen. Zukünftige Forschung sollte verstärkt longitudinale Designs verwenden, um die Dynamik von Alter, Lebensphasen und Generationen besser zu verstehen.

Expressive writing involves structured written exercises of self-disclosure for cognitive and affective processing of stressful experiences over several writing sessions. Using a 3x3 mixed design, we examined the effects of the intervention on work stress as well as work-related motivation and attitudes in 62 German participants. We found a sex-specific effect in the significant reduction of exhaustion in men in the experimental group. In contrast, women in the control group showed significantly higher levels of exhaustion. This effect was not found for women in the experimental group. Despite the limitations of our research in terms of sample differences in baseline levels, our research identifies an alleviating effect of expressive writing on emotional exhaustion as the core facet of burnout. Future research should specifically select individuals with higher levels of stress to address the limitations mentioned.

The setting of the experiment took place under the terms of a command post exercise (Stabs-Rahmenübung), held once a year at the Federal Academy for Civil Defense and Civil Protection (Bundesakademie für Bevölkerungs- und Zivilschutz—BABZ). The BABZ provides premises and technical facilities for advanced training, and the police officers spend a week focusing exclusively on learning and training for police staff work (polizeiliche Stabsarbeit). Mayring (2010) identified three aspects (cognition, emotion, action) influencing communication’s semiotic aspect. These three aspects were addressed during the mindfulness intervention used in the field study, with participants being asked to provide a short statement about their current state of cognition, emotion, and physical experience. The intervention was conducted before and after each of the two daily command post exercises for the experimental group (N = 46), while no intervention occurred for the control group (N = 58). Knowledge sharing and knowledge collecting were assessed with the Knowledge Donating and Knowledge Collecting Items (de Vries et al. 2016). While planned contrast analyses revealed no effect on knowledge donating, our data suggest a tendency for a positive influence of the mindfulness intervention on knowledge collecting. These differences between knowledge sharing and collecting might occur because knowledge collecting is more implicit and part of the process of building a shared mental model (Cannon-Bowers et al. 1993). The impact of knowledge collecting will be discussed in light of the self-determination theory (Ryan and Deci 2000) and the impact of individual and collective mindfulness in high-reliability organizations (Weick and Sutcliffe 2001), respectively high-responsibility teams (Hagemann et al. 2012).

Die Herausgeber reflektieren die Kernaussagen der Autoren, die eine Balance zwischen objektiver Diagnostik und subjektiver Intuition fordern und eine deutliche Diskrepanz zwischen wissenschaftlicher Theorie und unternehmerischer Praxis wahrnehmen. Die Rezeption im Themenheft zeigt ein breites Spektrum von Positionen: Während Intuition teils als wertvoller Impuls in komplexen Entscheidungsprozessen gesehen wird, warnen Kritiker vor ihrer Anfälligkeit für Biases. Die Herausgeber plädieren für integrative Verfahren und diagnostische Zugänge, die subjektive und objektive Ansätze verbinden, und betonen die Notwendigkeit eines differenzierten, praxisnahen Dialogs zwischen Wissenschaft und Praxis, um fundierte und zugleich flexible Entscheidungsprozesse zu gestalten.
