So far, health effects of long-term exposure to ambient ultrafine particles are not well understood, owing to a lack of exposure data and epidemiological studies. Methods We conducted a systematic review and meta-analysis on the health effects of long-term exposure to ultrafine particles, including studies published until December 2024. A meta-analysis was conducted for outcomes with at least four available effect estimates. Confidence in the body of evidence was evaluated using the Office of Health Assessment and Translation method. Results We identified 85 studies investigating various mortality, morbidity and subclinical outcomes. In meta-analyses of single-pollutant models, we found positive associations with natural mortality (hazard ratio 1.06, 95% CI 1.04–1.08) and C-reactive protein (10.14% increase (95% CI −0.51–21.99%) per 10 000 pt·cm−3 increase in long-term exposure to ultrafine particles, with low and inadequate levels of evidence, respectively. The remaining studies revealed overall limited evidence for adverse effects on a wide range of outcomes. Less than half of the studies adjusted for co-pollutants. Conclusion The evidence base on long-term health effects of ultrafine particles has increased substantially in the past decade, while the overall evidence for independent effects of long-term ultrafine particle exposure remains inadequate to low. More studies are needed to draw firm conclusions about the independent adverse effects of long-term ultrafine particles on various health end-points, with a special focus on the influence of co-pollutant adjustment.

This article examines how the experience of the pandemic has affected the willingness of scientists to engage with the public. Derived from a comprehensive survey of 4207 scientists at German universities and research institutions, animosity towards scientists during the pandemic has created a sense of insecurity that may cause them to withdraw from the public eye. Depending on the relative strength of two cognitive appraisals, the severity of the threat and the appropriateness of the retreat option, the likelihood of respondents engaging with the public varies significantly.

Using CuO–H2O nanofluid in a bottom-heated channel with circular expansion, we examine the complex interactions between forced convection, magnetic fields, and uoyancy effects. Through systematic numerical analysis, we explore the combined influences of Rayleigh, Reynolds, and Hartmann numbers on thermal performance. Our findings reveal significant heat transfer enhancement (up to 137 %) under optimal conditions, particularly with vertical magnetic field orientation at Re = 100 and Ha = 30. The results demonstrate how adiabatic blocks modify flow structures, with larger blocks diminishing vortex intensity while elevated Ra generates secondary vortices that interact with primary circulations. Magnetic field effects show notable dependence on orientation, with vertical fields generally promoting better heat transfer than horizontal configurations. To complement the numerical analysis, we develop a predictive model using Artificial Neural Network (ANN) for Nusselt numbers across various operating conditions, achieving over 99 % accuracy. The integrated computational-ANN approach offers significant advancements in optimizing thermal systems in various areas, ranging from electronics cooling to microfluidic devices.

This is important, since the increasing miniaturization and performance demands for electronic devices have led in a growing need for advanced thermal management systems capable of handling rapid transient loads. The novelty of the work lies in examining different heat sink layouts that optimize the heat dissipation capabilities of GR42 PCMs while minimizing size and weight for electronic cooling. The experimental testing was conducted using three configurations, namely no fin, circular fin and hexagonal fin, with three input powers (4 W, 8 W, and 12 W). The experimental results show that the hexagonal-fin heat sink, surface area is 25 % more than circular fins, exhibited superior thermal performance without significant variation in input power. Notably, the hexagonal-fin heat sink achieved the desired set point temperature of 55 ◦C in 33 % less time than the circular-fin design and 45 % less time than the heat sink without fins. Furthermore, the peak temperatures increased up to 21 % for circular fins. During the charging cycles, the enhancement ratios vary from 72 % and begin to narrow to 25 % during discharge cycles. The hexagonal-fin configuration also exhibited superior melting dynamics, completing the phase transition 44 % faster at higher input power than the circular fins, and established a thermal deviation of nearly 51 % less than finless heat sinks. These findings underscore the critical role of fin geometry and PCM integration in achieving uniform temperature distribution and improved energy storage efficiency. Overall, the hexagonal-fin heat sink with GR42 PCM shows strong potential as a passive cooling solution for low-power portable electronic devices.

The test was based on six acoustic scenes highlighting specific acoustic phenomena and for three complex, “real-world” spatial environments. The results demonstrate that most present simulation algorithms generate obvious model errors once the assumptions of geometrical acoustics are no longer met. As a consequence, they are neither able to provide a reliable pattern of early reflections nor do they provide a reliable prediction of room acoustic parameters outside a medium frequency range. In the perceptual domain, the algorithms under test could generate mostly plausible but not authentic auralizations, i.e., the difference between simulated and measured impulse responses of the same scene was always clearly audible. Most relevant for this perceptual difference are deviations in tone color and source position between measurement and simulation, which to a large extent can be traced back to the simplified use of random incidence absorption and scattering coefficients and shortcomings in the simulation of early reflections due to the missing or insufficient modeling of diffraction.

The performance of different interpolation techniques applied to sparsely sampled directivity measurements depends on the sampling grid used but also on the radiation pattern of the sources themselves. Therefore, we evaluated three established approaches for interpolation from a low-resolution sampling grid using high-resolution measurements of a representative sample of musical instruments as a reference. The smallest global error on average occurs for thin plate pseudo-spline interpolation. For interpolation based on spherical harmonics (SH) decomposition, the SH order and the spatial sampling scheme applied have a strong and difficult to predict influence on the quality of the interpolation. The piece-wise linear, spherical triangular interpolation provides almost as good results as the first-order spline approach, albeit with on average 20 times higher computational effort. Therefore, for spatial interpolation of sparsely sampled directivity measurements of musical instruments, the thin plate pseudo-spline method applied to absolute-valued data is recommended and, if necessary, a subsequent modeling of the phase KW - Source directivity KW - Spatial interpolation KW - Musical instruments Y1 - 2021 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:hbz:due62-opus-58992 SN - 1687-4722 VL - 2021 IS - 1 PB - Springer Nature ER - TY - JOUR A1 - Ackermann, David A1 - Böhm, Christoph A1 - Brinkmann, Fabian A1 - Weinzierl, Stefan T1 - The Acoustical Effect of Musicians’ Movements During Musical Performances JF - Acta Acustica united with Acustica N2 - Acoustic musical instruments act as dynamic sound sources communicating the expressive intentions of a performer to the audience in a dedicated spatial environment. From an acoustical point of view, the directivity of musical instruments is relevant both for the loudness and timbre of an instrument at a certain position in the audience, as well as for the spatial characteristics of the generated sound field. Musical instruments, however, are dynamic sound sources always moved by musicians as an element of their performance on stage. This work aims at assessing the acoustical effect and the perceptual relevance of these movements. For this purpose, we have recorded solo musical performances with all standard orchestral instruments with an optical motion tracking system, as well as the corresponding audio signals. The effect of the movements was evaluated by analysing the spectral fluctuation and the time-dependence of room acoustical parameters in a virtual acoustic environment in anechoic and reverberant conditions. In a subsequent listening test, an auralization of the static and dynamic musical performance was presented to listeners by binaural synthesis, showing that the signal-related fluctuations are clearly audible both in anechoic and reverberant situations. We discuss different approaches how to consider these effects for the simulation of natural acoustic sources in virtual acoustic reality.

While previous studies have generally examined the directivity of the static, unmoved instrument for specific notes played, we show the individual and combined contributions of these two factors to a temporal modulation of the radiation behavior, based on motion tracking of typical movement patterns for all instruments of a classical symphony orchestra and on the directivity measured for all partials over the entire pitch range of these instruments. The effect of this modulation, which is manifested by changes in timbre and room acoustic excitation, was determined by spectral variations in the free field and under reverberant conditions, as well as by a modulation of room acoustic parameters. Our results show that these effects are well above the just noticeable differences for all musical instruments and all perceptual variables considered. While the effect of motion dominates for brass instruments, string and woodwind instruments exhibit large note-related differences, which should be taken into account in virtual acoustic realities if an auditory liveliness comparable to physical reality is to be achieved.

First, a focus group with room acoustical experts determined relevant aspects of room acoustical impression in the form of a comprehensive list of 50 uni- and bipolar items in different categories. Then, n = 190 subjects rated their acoustical impression of 35 binaurally simulated rooms from 2 listening positions, with symphonic orchestra, solo trumpet, and dramatic speech as audio content. Subsequent explorative and confirmative factor analyses of the questionnaire data resulted in three possible solutions with four, six, and nine factors of room acoustical impression. The factor solutions, as well as the related RAQI items, were tested in terms of reliability, validity, and several types of measurement invariance, and were cross-validated by a follow-up experiment with a subsample of 46% of the original participants, which provided re-test reliabilities and stability coefficients for all RAQI constructs. The resulting psychometrically evaluated measurement instrument can be used for room quality assessment, acoustical planning, and the further development of room acoustical parameters in order to predict primary acoustical qualities of venues for music and speech.

Objective: Quantitative data collection of relationships between the subjective well-being of heart transplant patients and selected influencing factors was investigated. Material and Methods: In a random sample of 97 heart transplant patients, quality of life was measured with the MLDL, subjective well-being with the HSWBS, social support with the SUCE-4, social activities, personality traits with the BFI-10 and the UGTS, as well as disease management according to the EFK, and physical complaints with the ERSD-SC TM were determined using an online survey. Results: In addition to physical well-being, social life, personality traits, the type of disease (chronic or spontaneous), and functional capacity have a significant impact on subjective well-being. Conclusion: In addition to physical well-being, psychosocial monitoring should also be established in transplantation medicine, and the long-term involvement of psychotherapists, psychiatrists, and social workers should be considered. After a heart transplantation, caring for the mind is just as essential as caring for the body, as subjective well-being is a product of the reciprocal influences of physical and psychological states.

However, recent studies suggest that virtual environments can alter mental effort compared to real-world settings, for example, through increased perceptual complexity which in turn may affect auditory perception.This could bias experimental outcomes and compromise the ecological validity of studies conducted in VR. To investigate this, a 2 × 2 between-subjects experiment was conducted to assess whether VR environments increase mental effort and thereby influence auditory perception. A real office environment was visually reconstructed in Unity and presented to the participants via a head-mounted display (HMD) and compared to its real counterpart. Participants in both environments were asked to retrospectively rate the loudness and unpleasantness of dynamically rendered binaural office noise scenarios presented via headphones and to report perceived sound sources. Moreover, participants were divided into two groups to induce different levels of mental effort. One group was asked to listen only to the sounds, while the other performed the Stroop Color-Word interference test in parallel. The results show no significant difference in the overall induced mental effort between environment conditions. Furthermore, performing the Stroop test had an effect on loudness and unpleasantness that was mediated by subjective effort. The results also suggest that auditory jugment depend primarily on individual sound properties, regardless of the visual environment.

This mechanism enables automated leader and follower selection in Stackelberg games, which have gained traction in engineering. While leaders typically hold greater priority or influence, systematic methods for assigning leaders and followers remain limited, especially in large-scale applications. As a result, many rely on empirical analysis to assign leaders and followers, without confirming if the selected setup is optimal. Therefore, in this paper, we develop an automated mechanism to evaluate the influence of each player on the global objectives of modular manufacturing systems, applicable to both single- and multi-objective scenarios. We validate the proposed approach within an industrial control scenario, using a modular Bulk Good System and its larger-scale arrangement with sequential and serial-parallel processes. We focus on three objectives, including production flow disruption prevention, power consumption reduction, and production demand fulfilment. Finally, we implement a self-learning algorithm utilizing Modular State-based Stackelberg Games, where leaders and followers are selected using our approach, which leads to encouraging results.

Yet the conditions under which such augmentations yield positive experience remain unclear. In this study, we tested whether the experience of being augmented depends on compatibility with the given task. In a between-subject experimental vignette study (N=120 experienced VR users), participants watched first-person videos in one of three conditions: (1) reality-oriented object manipulation (control), (2) task-compatible augmentation (growing/shrinking), or (3) non-task-compatible augmentation (distant grasping). As expected, the augmentation-oriented design only led to a greater sense of augmentation when it was compatible with the task. In turn, the experience of augmentation was positively related to positive affect, need fulfillment, and hedonic quality. These findings suggest that unreal augmentations are beneficial, but only when the new abilities match the task.

Constructive journalism aims to address these issues by emphasizing solution-oriented reporting. However, research on its effects remains inconsistent, mainly due to vague definitions of constructive journalism and a lack of theoretical foundation. This paper first proposes a content-centered definition of constructive journalism, suggesting three dimensions: balance, matter-of-factness, and focus on solutions. Using a series of established theories, we then present a theoretical framework that models the impacts of the content dimensions in a chain of effects from emotions to cognitive and conative variables. Our approach offers a systematic basis for future research by enabling experimental analysis of operationalizable and empirically separable content dimensions and by integrating research on constructive journalism into a variety of established media effect theories. Thus, we meet the demand for a stronger theoretical focus and aim to clarify constructive journalism’s impact on audiences.

Virtual reality (VR) offers innovative opportunities to safely practice everyday tasks, such as street crossing. This study was designed as a feasibility and pilot study to explore acceptance, usability, and preliminary effects of a VR-based road-crossing intervention for older adults. It investigates the use of virtual reality (VR) as an innovative training tool to support senior citizens in safely navigating everyday challenges such as crossing roads. By providing an immersive environment with realistic traffic scenarios, VR enables participants to practice in a safe and controlled setting, minimizing the risks associated with real-world road traffic. Methods: A VR training application called “Wegfest” was developed to facilitate targeted road-crossing practice. The application simulates various scenarios commonly encountered by older adults, such as crossing busy streets or waiting at traffic lights. The study applied a single-group pre-post design. Outcomes included the Timed Up and Go test (TUG), Falls Efficacy Scale-International (FES-I), and Montreal Cognitive Assessment (MoCA). Results: The development process of “Wegfest” demonstrates how a highly realistic street environment can be created for VR-based road-crossing training. Significant improvements were found in the Timed Up and Go test (p = 0.002, d = 0.784) and fall-related self-efficacy (FES-I, p = 0.005). No change was observed in cognitive function (MoCA, p = 0.56). Participants reported increased subjective safety (p < 0.001). Discussion: The development of the VR training application “Wegfest” highlights the feasibility of creating realistic virtual environments for skill development. By leveraging immersive technology, both physical and cognitive skills required for road-crossing can be effectively trained. The findings suggest that “Wegfest” has the potential to enhance the mobility and safety of older adults in road traffic through immersive experiences and targeted training interventions. Conclusions: As an innovative training tool, the VR application not only provides an engaging and enjoyable learning environment but also fosters self-confidence and independence among older adults in traffic settings. Regular training within the virtual world enables senior citizens to continuously refine their skills, ultimately improving their quality of life.

Ergebnisse zeigen, dass die sozialräumliche Verortung der Schulen (gemessen über den Sozialindex NRW) keinen Einfluss auf die Prozessqualität im Ganztag (gemessen über Autonomie, das Interesse an Ganztagsangeboten und der Beziehung zu Betreuungspersonen) hat. Vertiefende Mehrebenenanalysen zeigen, dass insbesondere das Interesse an den Ganztagsangeboten und die Beziehungsqualität signifikant zum schulischen Wohlbefinden beitragen, während die Autonomie keinen signifikanten Einfluss aufweist. Mädchen zeigten ein höheres Interesse an Ganztagsangeboten als Jungen. Ein höherer Sozialindex ist mit geringerem Wohlbefinden assoziiert. Diese Ergebnisse unterstreichen die zentrale Bedeutung des Sozialraums und der Prozessqualität für das Wohlbefinden der Schüler*innen im Ganztag.

Beide Ebenen sind vergeschlechtlicht (Gender Visibility Gap). Dies zeigt sich darin, dass die Forschung von Wissenschaftlerinnen weniger sichtbar ist bzw. gemacht wird und somit weniger Anerkennung erhält als die von Kollegen, was neben anderen Faktoren dazu führen kann, dass Wissenschaftlerinnen das Hochschulsystem verlassen. Davon ausgehend stellt der Beitrag die Frage, welche Rolle der in diesem Kontext bisher wenig im Mittelpunkt der Forschung stehenden Hochschulkommunikation im Prozess der Sichtbarmachung von Wissenschaftlerinnen zukommt. Es wird vor dem Hintergrund macht- und repräsentationstheoretischer Perspektiven diskutiert, wie sich Mitarbeitende der Hochschulkommunikation im Prozess der Sichtbarmachung von Wissenschaftlerinnen positionieren und inwiefern sie sich hier in der (Mit-)Verantwortung sehen. Ein zentraler Befund ist, dass diese Akteursgruppe ihren Einfluss mit Rekurs auf wissenschaftsexterne, journalistische Kriterien, die es zu erfüllen gilt, ein Stück weit relativiert.

Andererseits wird der Begriff in der Fachdebatte aufgrund seiner analytischen Unschärfen sowie normativen Aufladungen kontrovers diskutiert. Zudem stößt der Partizipationsanspruch Sozialer Arbeit in der Praxis, insbesondere jener in arbeitsmarktpolitischen Maßnahmen der Jugendberufshilfe, auf Widersprüchlichkeiten innerhalb enger institutioneller Grenzen.

In diesem Zusammenhang wurden auch Konflikte als Partizipationsversuche verstanden. N2 - On the one hand, participation is a key concept of social work. On the other hand, the concept sparks controversy due to its occasional lack of analytical clarity and normative implications. In practice, especially in measures organised by youth vocational services based on labour market policies, tight institutional restrictions mean that social work’s aspiration for participation comes up against inconsistencies. Against this background, the views held by young people in a German pre-vocational measure on their opportunities to participate were reconstructed. In this context, conflicts are also understood as attempts to participate.

T1 - Enhanced prediction of heat transfer in jet impingement cooling using an artificial intelligence: A case study JF - Case Studies in Thermal Engineering N2 - This paper is about the gas turbine cooling model using the extended jet array. The aim of the present study is to explain the effect of the impinging jet configuration of elongated jet holes on the heat transfer distribution with a deep Convolutional Neural Network (CNN). CNNs preserve spatial relationships through convolutional operations—unlike traditional Artificial Neural Networks (ANNs), which require flattening of input data—allowing for higher accuracy with smaller datasets and faster training due to fewer trainable parameters. The goal is to understand how accurate and fast deep learning models with limited data can deliver predictions for complex systems such as jet impingement cooling. The proposed CNN model was compared with the numerical and experimental data. Jet impingement cooling was examined with four different Reynolds numbers (16250, 21700, 27100, 36250) and six dimensionless gaps between the jet and the target surface (G/D = 1, 2, 3, 4, 5, and 6). Mean and local Nusselt number (Nu) distributions were investigated in particular. G/D = 2 was selected as the test data for the model among the configurations. While the CFD model failed to identify this peak performance point, the CNN model accurately captured this maximum behavior despite being trained only on other configurations. Moreover, the CNN model demonstrated more suitable prediction accuracy in the first two jet impingement regions than the CFD data, especially in capturing peak Nusselt numbers and localized hot spots. It has been determined that the CNN model provided more accurate predictions of the local Nusselt numbers within the measurement region compared to the Computational Fluid Dynamics (CFD) study for the average Nu, the proposed CNN model showed a closer agreement to experimental data than numerical simulation by 4.15 % at the Re = 32500 and G/D = 2.

Umso wichtiger ist es, dass Befragungsinstitute verlässliche Prognosen liefern. Vom Wahlergebnis stark abweichende oder dem Wahlergebnis widersprechende Prognosen können nicht nur das Vertrauen in Wahlumfragen, sondern auch in Umfrageforschung generell schwächen. Zur Erklärung der Diskrepanzen zwischen den Prognosen der Institute und dem Wahlergebnis sind verschiedene inhaltliche und methodische Kriterien zu berücksichtigen. Aus methodischer Perspektive spielt neben dem Befragungszeitpunkt, der Stichprobenzusammensetzung und dem Umgang mit Rohdaten auch der Erhebungsmodus eine nicht zu unterschätzende Rolle. In der Forschung wird auf signifikante Unterschiede zwischen persönlich-mündlichen und Onlinebefragungen hingewiesen, was die Betrachtung der Befragungsmodi für Wahlforschung umso relevanter macht. In dieser Studie wird daher untersucht, wie sich die Ergebnisse von Onlinebefragungen und face-to-face Befragungen in der heißen Phase der Bundestagswahl 2021 unterscheiden. Hierfür werden die Ergebnisse von je zwei persönlich-mündlichen und zwei Onlinebefragungen miteinander verglichen. Das feldexperimentelle Design der Studie verdeutlicht, dass Wahlumfragen im Onlinemodus mit Quotenstichproben die Wahlbeteiligung überschätzen und Stimmanteile der CDU und SPD unter- sowie der Grünen, Linken und AfD überschätzen. Da der Befragungsmodus sowohl die Wahlberichterstattung als auch das Wahlverhalten beeinflussen kann, ist dessen Wirkung in weiteren Studien systematisch zu untersuchen.

Mod-SbSG enhances cooperative decision-making among self-learning agents within production systems by integrating State-based Potential Games (SbPG) with Stackelberg games. This hierarchical structure assigns more important modules of the manufacturing system a first-mover advantage, while less important modules respond optimally to the leaders’ decisions. This decision-making process differs from typical multi-agent learning algorithms in manufacturing systems, where decisions are made simultaneously. We provide convergence guarantees for the novel game structure and design learning algorithms to account for the hierarchical game structure. We further analyse the effects of single-leader/multiple-follower and multiple-leader/multiple-follower scenarios within a Mod-SbSG. To assess its effectiveness, we implement and test Mod-SbSG in an industrial control setting using two laboratory-scale testbeds featuring sequential and serial parallel processes. The proposed approach delivers promising results compared to the vanilla SbPG, which reduces overflow by 97.1%, and in some cases, prevents overflow entirely. Additionally, it decreases power consumption by 5%–13% while satisfying the production demand, which significantly improves potential (global objective) values.

The politics of the real is based on an interruption of identification and an abrupt end of continuity, and intensity, manifestation, and performance are the modalities of the politics of the real. First, intensity is the principle of punctualization. It denotes an anti-dialectic and anti-systematic enterprise that aims to leave behind the paradigm of continuity. It acts as the counter-principle to overcome the Hegelian dialectic and historicism. It concerns the dimension before the formation of identity and thus functions as a categorical rejection of ontological identity. Consequently, it evolves into a figure of future politics, because it denies identity and instead affirms new inventions. Second, manifestation is a matter of politics, because politics shows itself as a matter of visibility and demonstration. Ultimately, politics is the fight over manifestation. Furthermore, manifestation is the modality of existence of the collective, since a new arising collective always manifests itself in the space of images. Finally, performance is an action concept and thus opposed to the static world-model. Hence, the world appears as the place for restructuring and reshaping. Performance renders reference and the classical notion of mimesis obsolete. It undermines the distinction between original and copy and instead affirms the permanent generating of new relations and nexuses. Hence, it is the generation of freedom. Ultimately, it acts as a disappearing intermediary between virtual intensity and actual manifestation. It is an anti-metaphysical concept of possibility that differs strictly from metaphysical possibility. Thus, intensity, manifestation, and performance each correspond to the virtual, actual, and possible of the real and thus are to be denoted as modalities of the politics of the real.

T1 - Translating community-wide spectral library into actionable chemical knowledge: a proof of concept with monoterpene indole alkaloids JF - Journal of Cheminformatics N2 - With over 3000 representatives, the monoterpene indole alkaloids (MIAs) class is among the most diverse families of plant natural products. The MS/MS spectral space exploration of these complex compounds using chemoinformatic and computational mass spectrometry tools offers a valuable opportunity to extract and share chemical insights from this emblematic family of natural products (NPs). In this work, we first present a substantially updated version of the MIADB, a database now containing 422 MS/MS spectra of MIAs that has been uploaded to the GNPS library versus 172 initial entries. We then introduce an innovative workflow that leverages hundreds of fragmentation spectra to support the FAIRification, extraction and dissemination of chemical knowledge. This workflow aims at the extraction of spectral patterns matching finely defined MIA skeletons. These extracted signatures can then be queried against complex biological extract datasets using MassQL. By applying this strategy to an LC-MS/MS dataset of 75 plant extracts, our results demonstrated the efficiency of this approach in identifying the diversity of MIA skeletons present in the analyzed samples. Additionally, our work enabled the digitization of structural data for diverse MIA skeletons by converting them into machine-readable formats and thereby enhancing their dissemination for the scientific community. Scientific contribution A comprehensive investigation of the monoterpene indole alkaloid chemical space, aiming to highlight skeleton-dependent fragmentation similarity trends and to generate valuable spectrometric signatures that could be used as queries.

Samples are usually analyzed by liquid chromatography coupled with fragmentation mass spectrometry to acquire informative mass spectral ensembles. Such data is then exploited to establish relationships among analytes or samples (e.g., via molecular networking) and annotate metabolites. However, the comparison of samples profiled in different batches is challenging with current metabolomics methods since the experimental variation—changes in chromatographical or mass spectrometric conditions - hinders the direct comparison of the profiled samples. Here we introduce MEMO—MS2 BasEd SaMple VectOrization—a method allowing to cluster large amounts of chemodiverse samples based on their LC-MS/MS profiles in a retention time agnostic manner. This method is particularly suited for heterogeneous and chemodiverse sample sets. MEMO demonstrated similar clustering performance as state-of-the-art metrics considering fragmentation spectra. More importantly, such performance was achieved without the requirement of a prior feature alignment step and in a significantly shorter computational time. MEMO thus allows the comparison of vast ensembles of samples, even when analyzed over long periods of time, and on different chromatographic or mass spectrometry platforms. This new addition to the computational metabolomics toolbox should drastically expand the scope of large-scale comparative analysis.

In this context, perceived safety plays a critical role in their acceptance and implementation. Previous research had focused more on data security or specific digital technologies. There has also been a lack of participatory approaches to consider and empower healthcare recipients (and relatives), providers, and technology experts to broaden the phenomenon. Objective The aim of this study was to present a comprehensive perspective on the needs, influencing factors and related outcomes in the context of feeling safe with digital technologies in healthcare. Method A qualitative, exploratory, and participatory methodology was used with five guide-based focus group workshops. Each workshop explored one of five digital technology demonstrations provided at the beginning: (1) electronic health records (EHR), (2) robotics, (3) artificial intelligence (AI), (4) smart home, and (5) smart hospital. All participants were invited for a guide-based discussion. The study focused on the levels of ‘involvement’ and ‘collaboration’ by also empowering participation. The workshop target groups were actively involved in the development and execution of the workshops and were empowered. The data were analysed via a content analysis approach, with a mostly inductive procedure. Results Feeling safe was found to affect thoughts, emotions, and actions. For example, a higher level of perceived safety increased the acceptance of digital technologies, whereas a lower level of perceived safety decreased it. The corresponding needs and influencing factors differed in terms of their scope and focus depending on the context. The aspect of ‘control’ was most frequently addressed by all the target groups and was viewed as relevant in all the workshops. In general, digital technologies were viewed as supplements rather than substitutes for healthcare providers. Conclusion This study extends beyond the current state of research on perceived safety and the use of digital technologies in healthcare by providing a comprehensive overview of the corresponding needs and influencing factors at various levels, such as the individual, community-organizational, and system-society levels. The perceived safety of healthcare recipients and providers related to digital technologies should be taken into consideration to achieve positive implementation outcomes. N2 - Hintergrund Digitale Technologien werden im Gesundheitswesen immer häufiger eingesetzt. Hierbei spielt die wahrgenommene Sicherheit eine entscheidende Rolle für deren Implementierung. Bisherige Forschung konzentrierte sich eher auf die Datensicherheit oder auf spezifische digitale Technologien. Es fehlte ein partizipativer Ansatz, der es Leistungsempfangenden (deren Angehörigen), Leistungserbringenden und Technologieexpert:innen ermöglichte, die Sicht auf das Phänomen zu erweitern. Ziel Ziel war es daher erfahrungsbasiert Bedürfnisse, Einflussfaktoren und damit verbundenen Outcomes im Kontext des Sicherheitsgefühls digitaler Technologien im Gesundheitswesen zu erforschen. Methode Es wurde ein qualitatives, exploratives und partizipatives Design, basierend auf fünf leitfadengestützten Fokus-Gruppenworkshops durchgeführt. Eine von fünf digitalen Technologien ((1) elektronische Gesundheitsakten (EHR), (2) Robotik, (3) künstliche Intelligenz (AI), (4) Smart Home und (5) Smart Hospital), wurde zu Beginn oder während des Workshops vorgestellt und/oder konnte ausprobiert werden. Alle Teilnehmenden wurden zu einer leitfadengestützten Diskussion eingeladen. Die Partizipation wurde auf den Ebenen der „Beteiligung“ und „Zusammenarbeit“ gefördert, indem aktiv in die Entwicklung und Durchführung der Workshops einbezogen sowie zur Teilnahme befähigt wurde. Die Daten wurden mit Hilfe induktiver Inhaltsanalyse ausgewertet. Ergebnisse Das Gefühl der Sicherheit beeinflusst Gedanken, Gefühle und Handlungen. Beispielsweise kann ein höheres Maß an gefühlter Sicherheit die Akzeptanz digitaler Technologien erhöhen, während ein niedrigeres Maß diese verringern kann. Entsprechende Bedürfnisse und Einflussfaktoren unterschieden sich je nach Kontext in ihrem Umfang und Schwerpunkt. Der Aspekt der „Kontrolle“ wurde von allen Zielgruppen am häufigsten angesprochen und in allen Workshops als relevant angesehen. Digitale Technologien wurden eher als Ergänzung, denn als ein Ersatz für Leistungserbringende betrachtet. Schlussfolgerung Diese Studie geht über den aktuellen Stand der Forschung im Kontext wahrgenommener Sicherheit und digitaler Technologien im Gesundheitswesen hinaus, indem sie einen umfassenden Überblick über die Bedürfnisse und Einflussfaktoren von der individuellen bis hin zur System-/Gesellschaftsebene gibt. Die gefühlte Sicherheit sollte grundsätzlich berücksichtigt werden, um die Implementierung digitaler Technologien zu fördern.

A process of interest is the production of 1,3-butadiene (BD), which is primarily derived as a by-product of naphtha steam cracking. A sustainable alternative path involves converting renewable ethanol to BD via the Lebedev process, which requires a catalyst with balanced redox, acidic, and basic sites. Due to the necessity of a multifunctional catalyst, existing materials for this reaction are either comprised of catalyst mixtures or supported catalysts. In this study, we introduce a bulk material, saponite, containing M–O–Si sites, which combine required catalytic sites for the ethanol to BD (ETB) reaction in one material. The product composition in ethanol conversion were strongly dependent on the type of 3d-metal used, while no conclusive correlation between surface properties, conversion, and product composition was observed. Herein, using V-Sap*, we achieved an ethene productivity of 448 gethene kgcat−1 h−1 (74%) at 573.15 K. High acetaldehyde productivity was maintained with Cu-Sap* (466 gAcA kgcat−1 h−1, 49%) at 573.15 K and Zn-Sap (528 gAcA kgcat−1 h−1, 55%) at 723.15 K. Mg-Sap primarily produced ethene but also yielded 10 gBD kgcat−1 h−1 BD at 723.15 K. Higher BD outputs were observed with Ni-Sap (31 gBD kgcat−1 h−1 at 523.15 K) and Mn-Sap* (51 gBD kgcat−1 h−1 at 723.15 K). This underscores the potential of saponite-based materials for flexible product outputs in ethanol conversion, influenced by the choice of integrated 3d-metal.

JF - The Journal of the Acoustical Society of America N2 - Credibility is a crucial social factor that influences people's perception and decision-making. This study explores the acoustic attributes that define credible speech compared to neutral and ironic speech. A custom-built German corpus was developed, containing speech samples recorded from amateurs to enhance ecological validity. The study extracted a broad set of audio features from these samples, employing recursive feature elimination to identify the most influential attributes. These were then analyzed using a machine-learning-supported multinomial logistic regression model. The results indicated significant differences in the acoustic features associated with credible speech compared to neutral and ironic speech. Key findings include the role of a higher energy level (1st mel-frequency cepstral coefficient) in credible compared to neutral and ironic speech and a higher speaking rate in both credible and ironic compared to neutral speech. Also, irony is characterized by more high-frequency content (mean spectral centroid) compared to credible or neutral speech. Gender differences in spoken irony involve a greater influence of speaking rate in women's speech, while high pitch plays a more significant role in men's speech. This research thus contributes to the understanding of how credibility is conveyed through speech and offers insights for applications in communication, media, and artificial intelligence. The study also highlights the methodological advancements made by incorporating a diverse range of acoustic features and employing a robust machine-learning framework.

We investigate the dynamics of the stabilizing cap through in vitro reconstitution of microtubule dynamics in contact with microfabricated barriers, using the plus-end binding protein GFP-EB3 as a marker for the nucleotide state of the tip. The interaction of growing microtubules with steric objects is known to slow down microtubule growth and accelerate catastrophes. We show that the lifetime distributions of stalled microtubules, as well as the corresponding lifetime distributions of freely growing microtubules, can be fully described with a simple phenomenological 1D model based on noisy microtubule growth and a single EB3-dependent hydrolysis rate. This same model is furthermore capable of explaining both the previously reported mild catastrophe dependence on microtubule growth rates and the catastrophe statistics during tubulin washout experiments.

Both the sidewalls of the enclosure are cooled and undulated with varying undulation numbers. The lower wall is partially undulated following a semi-circular-shaped object and is heated isothermally. The horizontal walls are insulated. The cavity is occupied with Cu-Al2O3/water-based hybrid nanofluid and porous substances under the impact of the evenly applied horizontal magnetic field. This work significantly contributes to the existing research rendering an exhaustive understanding of the hydrothermal flow-physics as well as irreversibility production of a hybrid nanofluid in the cavity having surface undulation. The Galerkin weighted finite element method is utilized to solve the mathematical model. The hydrothermal performance of the thermal system is considerably influenced by various pertinent factors such as Darcy-Rayleigh number, Darcy number, Hartmann number, and number of undulations. The wall undulations have a critical role in altering the hydrothermal performance. Heatlines are used to analyse heat transport dynamics from the protruded hot surface to the heat sink. The protruded heater wall induces the formation of a hot upward plume in the nearest fluid layers. The flow divides into two parts forming a pair of circulations due to symmetrical cooling at the sidewalls. The flow behaviours are significantly dampened by increasing the Hartmann number. The associated total entropy generation is also demonstrated. This study contributes to the existing domain knowledge and provides insights for designing and optimizing similar thermal systems.

The most common approach consists of dispersing small particles of dry ice, silver iodide, or other salts in the atmosphere. Here we show, using field experiments conducted under various atmospheric conditions, that laser filaments can induce water condensation and fast droplet growth up to several μm in diameter in the atmosphere as soon as the relative humidity exceeds 70%. We propose that this effect relies mainly on photochemical formation of p.p.m.-range concentrations of hygroscopic Hno3, allowing efficient binary Hno3–H2o condensation in the laser filaments. Thermodynamic, as well as kinetic, numerical modelling based on this scenario semiquantitatively reproduces the experimental results, suggesting that particle stabilization by Hno3 has a substantial role in the laser-induced condensation.

This study analyzes the historical evolution of topics and conveyed affect in popular music lyrics in Germany from 1954 to 2022, using LDA-based topic modeling and transformer-based sentiment analysis. These results show that Love & Relationships is the most referenced topic, with Dreams & Longings prominent until the mid-1960s and Society & Status rising from 2017. The sentiment analysis reveals a significant decline in positive sentiment since the mid-1960s, accompanied by increases in negative, ambiguous, and neutral sentiments. These trends may reflect broader societal changes, including shifts in cultural values, rising individualism, and increasing mental health issues. The study highlights the evolving nature of popular music and its reflection of social dynamics.

This paper highlights publics that present themselves as counterpublics but which in actual fact reinforce existing hierarchies, particularly patriarchal structures. The case study of Girl Defined Ministries, a fundamentalist evangelical influencer duo based in Texas, links the research fields of digital religion and anti-feminist defensive publics, revealing parts of anti-feminism online that have hitherto been the reserve of digital religion studies. A consideration of the national history and religious developments of recent decades in the United States allows for a deeper understanding of this type of religious influencer. Girl Defined post content about their concept of “Biblical womanhood” on multiple platforms. In the present study, 56 blog articles by Girl Defined were analysed using qualitative content analysis through the analytical lens of the Social Identity model of Deindividuation Effects (SIDE), which reflects on how group identity is formed by simultaneously enhancing in-group and devaluing out-group norms. The findings demonstrate that Girl Defined portray the out-group, feminism, as an anti-God ideology responsible for the collective misery of women in Western societies, and hold women responsible for their own discontent by choosing the wrong path. Girl Defined therefore promote their in-group values, gender roles for women defined by God, and submission to men as the only way to live a joyful life. Presenting themselves as a persecuted and ostracised counterpublic to a feminist mainstream is central to Girl Defined’s argument. The paper adds to the existing literature on women anti-feminist and religious influencers as a development of mediatization.

Die transnationale Aktionsform der kollektiven Busfahrten in die Niederlande wird dabei als (doppelsinnige) Freiheitsaktion und vier-dimensional ver-körperte Direkte Aktion im Sinne anarchistischer Selbsthilfe am bundesdeutschen Staat vorbei analysiert. Es handelte sich um eine frauenbewegte Handlungsoffensive machtvoller Gemeinschaftlichkeit, die, 1975 beginnend, solidarische Kollektivität und Öffentlichkeit als Strategie nutzte, um eine faktische Durchsetzung des Selbstbestimmungsrechts zu erwirken: In der Form der politischen Aktion wurde das Ziel selbst sichtbar gemacht (Konkretheit) und dieses unmittelbar durch die Abtreibungen erreicht (Implementierung). Empowernd schuf die Aktionsform selbstorganisierte Handlungsspielräume, wies dabei Angst und Scham zurück und delegitimierte das Gesetz. Nach einer reflexiven Kritik wurde die Aktionsform 1977 eingestellt. Resümierend werden die vorliegenden 11 Prinzipien einer Konzeption feministischen Widerstands um die Aktionsformaspekte feministische Reflexion und Solidarität erweitert. N2 - This article deals with a form of political action in which feminists crossed a line in protest against the ban on abortions in the FRG. These collective bus rides to the Netherlands are analyzed as a transnational political action for (ambiguous) freedom and a four-dimensional Direct embodied action in the sense of the self-help doctrine of anarchy – in other words, without involving the State. Instead, this was a female-led campaign of an empowered community which in 1975 began to use solidarity, collectivity, and publicity to enforce the right to self-determination. The form of this action makes the goal visible (concreteness) and that goal was directly achieved when the abortions were carried out (implementation). The form of action was self-empowerment and it created new self-organized scope for action; it also contributed to overcoming fear and shame and delegitimized the law. After some self-critical reflection, this form of action was abandoned in 1977. The discussion concludes by arguing that feminist reflection and solidarity, that is aspects borrowed from this form of action, should be added to the 11 established principles of feminist resistance T2 - Political action for freedom in the women’s movement: Collective bus rides to abortion clinics in the Netherlands (1975–1977) as a form of embodied protest bodily protest KW - Frauenbewegung KW - Schwangerschaftsabbruch KW - Protest KW - Selbstbestimmungsrecht KW - Feminismus KW - Anarchafeminismus KW - FBSK_Webseite Y1 - 2022 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:hbz:due62-opus-51313 SN - 1868-7245 VL - 14 IS - 1 SP - 134 EP - 151 PB - Barbara Budrich ER - TY - JOUR A1 - Erdmann, Matthias A1 - von Berg, Markus A1 - Steffens, Jochen T1 - Development and evaluation of a mixed reality music visualization for a live performance based on music information retrieval JF - Frontiers in Virtual Reality N2 - The present study explores the development and evaluation of a mixed reality music visualization for a live music performance. Real-time audio analysis and crossmodal correspondences were used as design guidelines for creating the visualization, which was presented through a head-mounted-display. To assess the impact of the music visualization on the audience’s aesthetic experience, a baseline visualization was designed, featuring the same visual elements but with random changes of color and movement. The audience’s aesthetic experience of the two conditions (i.e., listening to the same song with different visualizations) was assessed using the Aesthetic Emotions Scale (AESTHEMOS) questionnaire. Additionally, participants answered questions regarding the perceived audiovisual congruence of the stimuli and questionnaires about individual musicality and aesthetic receptivity. The results show that the visualization controlled by real-time audio analysis was associated with a slightly enhanced aesthetic experience of the audiovisual composition compared to the randomized visualization, thereby supporting similar findings reported in the literature. Furthermore, the tested personal characteristics of the participants did not significantly affect aesthetic experience. Significant correlations between these characteristics and the aesthetic experience were observed only when the ratings were averaged across conditions. An open interview provided deeper insights into the participants’ overall experiences of the live music performance. The results of the study offer insights into the development of real-time music visualization in mixed reality, examines how the specific audiovisual stimuli employed influence the aesthetic experience, and provides potential technical guidelines for creating new concert formats.
