These fuels can help reduce detrimental emissions like carbon monoxide and unburned hydrocarbons and enhance octane ratings. Among these oxygenates, ethyl acetate (EA), a small alkyl ester sourced from biomass, emerges as a clean, promising energy carrier. It serves as a surrogate fuel to facilitate investigations into the combustion behaviours of biodiesel. Despite its importance, the literature knowledge of EA combustion characteristics is limited. Therefore, this study aims to broaden the knowledge of the combustion behaviour of this type of oxygenated fuel compound. In this study, we measured the laminar burning velocities of EA by employing a heat flux burner and a closed combustion vessel over the equivalence ratios of 0.7 – 1.7, pressures of 1 – 10 bar and temperatures ranging from 353 – 423 K. Further, we also measured the NOx emissions in exhaust gas of the premixed flames fueled by EA/air for the first time over the equivalence ratio of 0.8 – 1.2. Additionally, we employed a non-premixed counterflow flame setup for extensive characterisation of species and their concentration under diverse conditions encompassing various strain rates and oxygen concentrations. Finally, we utilized these newly measured data to construct and validate a detailed kinetic model developed as part of this work. The newly developed model will help characterize the combustion properties of EA.

T1 - One-dimensional turbulence modeling of a turbulent counterflow flame with comparison to DNS T2 - Combustion and Flame N2 - The one-dimensional turbulence (ODT) model is applied to a reactant-to-product counterflow configuration and results are compared with DNS data. The model employed herein solves conservation equations for momentum, energy, and species on a one dimensional (1D) domain corresponding to the line spanning the domain between nozzle orifice centers. The effects of turbulent mixing are modeled via a stochastic process, while the Kolmogorov and reactive length and time scales are explicitly resolved and a detailed chemical kinetic mechanism is used. Comparisons between model and DNS results for spatial mean and root-mean-square (RMS) velocity, temperature, and major and minor species profiles are shown. The ODT approach shows qualitatively and quantitatively reasonable agreement with the DNS data. Scatter plots and statistics conditioned on temperature are also compared for heat release rate and all species. ODT is able to capture the range of results depicted by DNS. However, conditional statistics show signs of underignition.

However, the results of this method may become too optimistic for non-standard gears with custom root fillets, large pressure angles or asymmetric teeth, since the effect of general mean stresses on the local tooth root strength are neglected. Therefore, a more generic calculation method is suggested, which considers the mean stress influence by utilizing the Haigh diagram. Both approaches are then used as basis of root fillet shape optimizations. A comparison of results demonstrates significant differences in the safety assessment and the resulting root geometry.

A surface oriented formulation is derived, in which the three-dimensional solid is described by its boundary surfaces and a radial scaling center. Scaling the boundary surfaces with respect to the scaling center yields a parameterization of the complete solid. The definition of the boundary surfaces is sufficient for the description of the solid. Thus, the formulation conforms ideally to the boundary representation modeling technique used in CAD. In the present approach, no tensor-product structure of three-dimensional objects is exploited to parameterize the physical domain. The weak form of the equation of motion and the weak form of the Neumann boundary conditions are enforced only at the boundary surfaces. It leads to a transformation of the governing partial differential equations of elasticity to an ordinary differential equation (ODE) of Euler type. Solving the ODE leads to the displacement in the radial scaling direction. In the present approach, the isogeometric Galerkin finite element method is employed to describe the geometry of the boundary surfaces and also to approximate the displacement response of the boundary surfaces. It exploits two-dimensional NURBS objects to parameterize the boundary surfaces. The final Euler type ODE is solved by the NURBS based collocation method. The displacement response in the radial scaling direction is approximated by the NURBS basis functions. Hence, the method can be extended to nonlinear problems. The accuracy of the method is validated against analytical solutions. In general, the proposed formulation is able to model solids bounded by an arbitrary number of surfaces.

It combines the merits of the so-called scaled boundary finite-element method (SB-FEM) and the isogeometric collocation method. For the analysis, the boundary scaling technique of SB-FEM is adopted. It leads to a formulation, where only the boundary of a structure is discretized. Here, the NURBS basis functions are employed for the description of the geometry of the boundary as well as for the approximation of the displacements at the boundary. This is in accordance with the boundary representation modeling technique, which is commonly employed in computer aided design software. The inner domain is described by a radial scaling parameter. Applying the weak form only in circumferential direction the governing partial differential equations of elasticity are transformed to an ordinary differential equation (ODE) of Euler type, where the unknown displacements are a function of the radial scaling parameter. In the present work a NURBS based collocation scheme is introduced to solve this equation. NURBS basis functions are suggested for the approximation of the displacements in scaling direction. The higher continuity provided by NURBS allows to use collocation to solve the ODE directly instead of using the weak form in scaling direction. The proposed approach is validated by comparison with the eigenvalue solution of the ODE. It is remarked that the eigenvalue solution is restricted to linear problems, whereas the proposed method could be extended to nonlinear problems. In general, the presented formulation will allow to model patches bounded by an arbitrary number of contour boundaries. The accuracy of the proposed approach is analyzed and estimated with respect to analytical solutions. The computational cost is investigated with the help of numerical examples and is compared to isogeometric Galerkin approach.

Scaling at supply voltages of 1V and below also implies a rising level of stress which drives aging effects that reduce switching speed and the expected life time. Additionally, vulnerability from particle radiation is increased. Hence, fault detection and on- line correction become a must for many applications. However, not only fault tolerance but self-awareness becomes also an advantage. Provided that by being aware of its own healthy state allow optimized configurations regarding system operation modes and configurable hardware mechanism. This paper shows a preliminary work in a configurable circuit and explores its configuration possibilities when integrated into a complete system.

In order to solve PDF transport equations, the main trend of previous studies rely on Monte Carlo method with Lagrangian particle tracking. However, as with any Lagrangian based approach, the scalability of the parallelized simulations of such method is less than satisfactory. An Eulerian stochastic field model has been presented recently by Dumond et al. [1] to simulate cavitating flows. Their model uses a fully compressible density based solver. Here we present an adapted version using an iso-thermal cavitation model adopting the homogeneous mixture assumption in a pressure based flow solver which is more relevant to engine simulations. A PDF method is used to represent a distribution of vapour volume fractions, based on which the Eulerian stochastic field (ESF) method is applied to perform a three-dimensional large eddy simulation (LES) of the cavitation phenomena inside an academic fuel injector configuration. The numerical model is based on a volume of fluids approach and coupled with a pressure based solver for the flow field, and is implemented in the framework of the open source C++ toolbox OpenFOAM. The result of the ESF simulation is compared against that from a typical single volume fraction solver for validation. Vortex structures and its correspondence to cavitation are shown, and the behaviour of the PDF at different probe locations at different times are acquired to demonstrate the potential of the ESF model in capturing both transient and stochastically steady cavitation.

In this work, we investigate possible interactions of this promising drug candidate with ATP-binding cassette (ABC) drug efflux transporters and cytochrome P450 biotransformation enzymes (CYPs), which play major roles in multidrug resistance (MDR) and pharmacokinetic drug-drug interactions (DDIs). Accumulation studies showed that ensartinib is a potent inhibitor of ABCB1 and ABCG2 transporters. Additionally, incubation experiments with recombinant CYPs showed that ensartinib significantly inhibits CYP3A4 and CYP2C9. Subsequent molecular docking studies confirmed these findings. Drug combination experiments demonstrated that ensartinib synergistically potentiates the antiproliferative effects of daunorubicin, mitoxantrone, and docetaxel in ABCB1, ABCG2, and CYP3A4-overexpressing cellular models, respectively. Advantageously, ensartinib’s antitumor efficiency was not compromised by the presence of MDR-associated ABC transporters, although it acted as a substrate of ABCB1 in Madin-Darby Canine Kidney II (MDCKII) monolayer transport assays. Finally, we demonstrated that ensartinib had no significant effect on the mRNA-level expression of examined transporters and enzymes in physiological and lung tumor cellular models.

Whole-cell modeling has been regarded as the central aim of systems biology but also as a grand challenge, which plays essential roles in current and future systems biology. In this paper, we analyze whole-cell modeling challenges and requirements and classify them into three aspects (or dimensions): heterogeneous biochemical networks, uncertainties in components, and representation of cell structure. We then explore how to use different Petri net classes to address different aspects of whole-cell modeling requirements. Based on these analyses, we present a Petri nets-based framework for whole-cell modeling, which not only addresses many whole-cell modeling requirements, but also offers a graphical, modular, and hierarchical modeling tool. We think this framework can offer a feasible modeling approach for whole-cell model construction.

The tooth root load capacity often is a limiting design criterion driving minimum face widths and hence the weight of gears. Consequently, strategies for optimizing the tooth root load capacity of gears are explored in this thesis. Two methods for tooth root load capacity analysis – a maximum tensile stress method derived from ISO 6336 and a local fatigue approach taking into account mean stress infl – are introduced and ompared to each other with respect to their applicability to optimization problems. A study with 2D fi element models of unidirectionally loaded sun gears reveals that the local fatigue analysis method should be preferred over the common approach of minimizing the maximum tooth root stress, since applying both methods as optimization targets results in diff nt tooth root shapes and a vast overestimation of safety gains when only tensile stresses are considered. Due to alternating loading, planet gears usually have a lower tooth root load capacity than other gears. Additionally, they are often designed with thin rims making the gear body lighter but also more elastic. Therefore, the tooth root shape of a thin-rimmed planet gear is optimized to explore possible interactions. The results show that overly thin rims negatively affect the maximization of tooth root safety. Hence, it is necessary to conduct multi-objectiveoptimizations of planet gears, which maximize tooth root safety and minimize mass simultaneously by optimizing tooth root shape, rim geometry and face width. The efficacy of this approach is demonstrated for 3D gear simulation models of spur as well as double helical planet gears. Pareto-optimal designs show significant improvements compared to the baseline design. Moreover, investigations demonstrate the opportunity to vastly decrease the computational cost of multi-objective optimizations by scalarizing them and using the result to approximate parts of the Pareto front.

A1 - Arellano-García, Harvey T1 - Big data and machine learning: A roadmap towards smart plants T2 - Frontiers of Engineering Management N2 - Industry 4.0 aims to transform chemical and biochemical processes into intelligent systems via the integration of digital components with the actual physical units involved. This process can be thought of as the addition of a central nervous system with a sensing and control monitoring of components and regulating the performance of the individual physical assets (processes, units, etc.) involved. Established technologies central to the digital integrating components are smart sensing, mobile communication, Internet of Things, modelling and simulation, advanced data processing, storage and analysis, advanced process control, artificial intelligence and machine learning, cloud computing, and virtual and augmented reality. An essential element to this transformation is the exploitation of large amounts of historical process data and large volumes of data generated in real-time by smart sensors widely used in industry. Exploitation of the information contained in these data requires the use of advanced machine learning and artificial intelligence technologies integrated with more traditional modelling techniques. The purpose of this paper is twofold: a) to present the state-of-the-art of the aforementioned technologies, and b) to present a strategic plan for their integration toward the goal of an autonomous smart plant capable of self-adaption and self-regulation for short- and long-term production management.

In recent years, PCA models based on various norms have been extensively studied to improve the robustness. However, on the one hand, these algorithms do not consider the relationship between reconstruction error and covariance; on the other hand, they lack the uncertainty of considering the principal component to the data description. Aiming at these problems, this paper proposes a new robust PCA algorithm. Firstly, the L2,p-norm is used to measure the reconstruction error and the description variance of the projection data. Based on the reconstruction error and the description variance, the adaptive probability error minimization model is established to calculate the uncertainty of the principal component's description of the data. Based on the uncertainty, the adaptive probability weighting PCA is established. The corresponding optimization method is designed. The experimental results of artificial data sets, UCI data sets and face databases show that RPCA-PW is superior than other PCA algorithms.

However, the heterogenous roles contributed by a single type of filler remain uncommon in this field. Here the endowment of various modifications to a 1,8‐octanediol/1,12‐dodecanedioic acid/citric acid (OD/DDA/CA) matrix through the incorporation of iron oxide nanoparticles (IONPs) is reported. Owing to the relaxation and hysteresis loss behaviors of IONPs when exposed to an alternating magnetic field (AMF), the composites demonstrate a magnetothermal response. Similarly, the excitation and relaxation of electrons in IONPs under near‐infrared light (NIR) enable photothermic‐responsiveness. In combination, two findings nurtured an observed shape‐memory effect when the samples are under actuation by these indirect stimuli, where a shape recovery ratio (≥98%) and reversible strain (≤7%) are recorded. Moreover, the catalytic role of IONPs aided transesterification in the covalent network, demonstrated by successful repeated cycles of shape reconfiguration of the samples. This work highlights the prospectives of multifunctional composite fillers in the exploration of bio‐derived composite smart materials.

In October 2020, we conducted a survey on digital health technology use in Germany. This study aimed to conduct a second survey to investigate in more detail the internet use in health context and digital technology use for health promotion and disease prevention in Germany. Methods: A cross-sectional, nationwide telephone survey was conducted in November 2022. Anonymous data on internet and digital technology use, digital health literacy, and sociodemographic characteristics were analysed using descriptive statistics and binary logistic regressions. Results: The 1020 participants were aged 18–92 years, 53% were male, 62% completed primary or secondary education, 71% resided in large cities, and 45% reported a country-average net household income. Overall, 61% reported internet use in health context via 1–4 devices. Among those, more than 50% used the internet and apps to obtain general health information and less than 50% used digital technologies for physical activity promotion or cancer prevention. Overall, 34% were confident in using the internet for health decisions and 71% preferred to receive health information non-digitally (e.g. on paper). Internet, app, and digital technology use were associated with higher digital health literacy and income, and residence in larger cities. Digital technologies were used for physical activity promotion by younger and for cancer prevention by older participants. Conclusion: The internet and digital technologies were predominantly used to obtain health information, but less often for health promotion and disease prevention in 2022 in Germany. While health app and digital technology use for physical activity promotion increased, the confidence in using online information for health decisions decreased in 2022 relative to 2020. Factors that promote confidence in online health information and digital technology use for health promotion and disease prevention need to be investigated in future studies.

Nonetheless, the material’s high thermal conductivity and low absorption of infrared light can introduce process instabilities, resulting in defects such as pores. This study employs a hybrid approach that combines in situ synchrotron X-ray imaging with compressible multiphysics process simulation to elucidate pore-forming mechanisms during laser beam welding of copper. High-speed synchrotron X-ray imaging with an acquisition rate of 20,000 images/second facilitates the identification of relevant process regimes concerning pore formation during laser beam welding of copper with a wavelength of 1070 nm. Furthermore, in situ observations with high temporal and spatial resolution present a unique database for extensive validation of a multi-physics process simulation based on welding processes using different concentric intensity distributions. These validated simulation results enable thorough comprehension of process-related pore formation based on the interaction between keyhole, melt pool and resulting flow field. The findings show that pore formation is driven by four different mechanisms: bulging, spiking, upwelling waves at the keyhole rear wall and melt pool ejections. The synergy of high- speed synchrotron X-ray imaging and multi-physics modeling provides a fundamental understanding of the chronological sequence of events leading to process-related pore formation during laser beam welding of copper.

This study aimed to compare the results of two nationwide surveys of internet users in Germany that investigated the use pattern, the attitudes towards, and the factors associated with digital technology use in health context. Methods: This study adheres to the ethical guidelines according to the Declaration of Helsinki. Two cross-sectional surveys of internet users living in Germany were performed in 2020 (survey 1) and 2022 (survey 2). Participants were recruited from two different consumer panel samples owned by a market research institute (Cerner Enviza GmbH). Participants provided verbal informed consent for participation in the study according to the Cerner Enviza data privacy policy. Computer-assisted telephone interviews were conducted by Cerner Enviza using questionnaires with 28-30 items developed by study authors. Anonymous data were purchased and analysed by study authors using descriptive statistics. Associations between digital technology use and participant characteristics were tested using binary logistic regression analyses. Results: The participants were adult internet users (survey 1: n=991; survey 2: n=1020). Participant characteristics were similar in both surveys (47-52% female, 50-55% aged 40-65 years, 62-66% with less than tertiary education, 42-45% with less than country-average household income, 81-82% residents in former West Germany, and 67-71% residents in large cities). A similar number of participants in both surveys reported digital technology use in any health context (57-61%) and rated digital technologies for physical activity promotion as easy to use (87-92%). Digital technology use increased in 2022 relative to 2020. Specifically, more participants reported health app (63% vs. 36%) and digital technology use for physical activity promotion (any use: 44% vs. 31%; weekly-daily use: 91% vs. 64%) in 2022 vs. 2020. In contrast, digital health literacy decreased in 2022 relative to 2020. Specifically, less participants had high digital health literacy (57% vs. 69%) and were confident in using online information for health decisions (34% vs. 43%) in 2022 vs. 2020. Digital technology use was associated with higher digital health literacy and younger age (in both surveys), higher income (in survey 1) and residence in larger cities (in survey 2). Conclusion: Digital technologies targeting some health domains, such as physical activity promotion are frequently used and accepted by the users. However, digital health literacy and especially the confidence in using online information for health decisions appear to have decreased in 2022 relative to 2020. Factors that promote digital technology use for health promotion and disease prevention need to be investigated in future studies. Considering that digital health literacy is associated with digital technology use, further research on user needs and preferences is required to understand the reasons for reduction in such literacy in this study.

Among these concepts, resistive random access memory (RRAM) devices allow fast and nonvolatile operation. However, building large memristive systems is still challenging since large analog circuits have to be designed and integrated. In this paper, we propose a novel solution - the implementation of digital standard cells by the means of RRAM devices. While this methodology is universal, with applications ranging from few-device-circuits to large macroblocks, we demonstrate it for a 2T2R-cell. The benefits of using RRAM devices are demonstrated by implementing a NAND standard cell merely consuming the area of two transistors. This cell is about 25 % smaller than the equivalent CMOS NAND in the same technology. We use these cells to implement a half adder, beating the area of the equivalent CMOS implementation using more sophisticates gates by 15 %. Lastly, we fully integrate this novel standard cell into a digital standard cell library and perform a synthesis and layout of a RISC-V CPU core.

This study investigated the use and attitudes toward digital technologies in health context using a nationwide survey. Methods Adult internet users (n=1020) from 16 federal states in Germany participated in computer-assisted telephone interviews in November 2022. Data were analyzed using descriptive statistics and regression analyses. Results Overall, 61% of participants reported internet use in health context. Among the users, digital technologies were used to obtain general health information by 63% and to support physical activity or to obtain information on cancer by less than 50%. Over 90% of users rated such technologies as easy to use and useful to obtain health information, to support physical activity or to obtain information on cancer. However, confidence in using the internet for health decisions was low. Digital technology use in health context was associated with higher eHealth literacy. Digital technologies were preferred by younger participants to support physical activity and by older participants to obtain information on cancer. Conclusion Although digital technologies are easy to use, the use of digital technologies for health promotion and disease prevention and confidence in using the internet for health decisions were low among internet users in this study. Factors that promote digital technology use for health promotion and prevention need to be investigated in further studies.

I. Conservative Eulerian formulation and application to supersonic channel flow T2 - Physics of Fluids N2 - Accurate but economical modeling of supersonic turbulent boundary layers is a standing challenge due to the intricate entanglement of temperature, density, and velocity fluctuations on top of the mean-field variation. Application of the van Driest transformation may describe well the mean state but cannot provide detailed flow information. This lack-in modeling coarse and fine-scale variability is addressed by the present study using a stochastic one-dimensional turbulence (ODT) model. ODT is a simulation methodology that represents the evolution of turbulent flow in a low-dimensional stochastic way. In this study, ODT is extended to fully compressible flows. An Eulerian framework and a conservative form of the governing equations serve as the basis of the compressible ODT model. Computational methods for statistical properties based on ODT realizations are also extended to compressible flows, and a comprehensive way of turbulent kinetic energy budget calculation based on compressible ODT is put forward for the first time. Two canonical direct numerical simulation cases of supersonic isothermal-wall channel flow at Mach numbers 1.5 and 3.0 with bulk Reynolds numbers 3000 and 4880, respectively, are used to validate the extended model. A rigorous numerical validation is presented, including the first-order mean statistics, the second-order root mean square statistics, and higher-order turbulent fluctuation statistics. In ODT results, both mean and root mean square profiles are accurately captured in the near-wall region. Near-wall temperature spectra reveal that temperature fluctuations are amplified at all turbulent scales as the effects of compressibility increase. This phenomenon is caused by intensified viscous heating at a higher Mach number, which is indicated by the steeper profiles of viscous turbulent kinetic energy budget terms in the very near-wall region. The low computational cost and predictive capabilities of ODT suggest that it is a promising approach for detailed modeling of highly turbulent compressible boundary layers. Furthermore, it is found that the ODT model requires a Mach-number-dependent increase in a viscous penalty parameter Z in wall-bounded turbulent flows to enable accurate capture of the buffer layer.

Full compressible modification and application to shock–turbulence interaction T2 - Physics of Fluids N2 - One-dimensional turbulence (ODT) is a simulation methodology that represents the essential physics of three-dimensional turbulence through stochastic resolution of the full range of length and time scales on a one-dimensional domain. In the present study, full compressible modifications are incorporated into ODT methodology, based on an Eulerian framework and a conservative form of the governing equations. In the deterministic part of this approach, a shock capturing scheme is introduced for the first time. In the stochastic part, one-dimensional eddy events are modeled and sampled according to standard methods for compressible flow simulation. Time advancement adjustments are made to balance comparable time steps between the deterministic and stochastic parts in compressible flows. Canonical shock–turbulence interaction cases involving Richtmyer–Meshkov instability at Mach numbers 1.24, 1.5, and 1.98 are simulated to validate the extended model. The ODT results are compared with available reference data from large eddy simulations and laboratory experiments. The introduction of a shock capturing scheme significantly improves the performance of the ODT method, and the results for turbulent kinetic energy are qualitatively improved compared with those of a previous compressible Lagrangian ODT method [Jozefik et al., “Simulation of shock–turbulence interaction in non-reactive flow and in turbulent deflagration and detonation regimes using one-dimensional turbulence,” Combust. Flame 164, 53 (2016)]. For the time evolution of profiles of the turbulent mixing zone width, ensemble-averaged density, and specific heat ratio, the new model also yields good to reasonable results. Furthermore, it is found that the viscous penalty parameter Z of the ODT model is insensitive to compressibility effects in turbulent flows without wall effects. A small value of Z is appropriate for turbulent flows with weak wall effects, and the parameter Z serves to suppress extremely small eddy events that would be dissipated instantly by viscosity.

Our cross-sectional survey was conducted using a panel sample of 1020 adult internet users living in Germany (age: 18-92 years, 47% female). Computer-assisted telephone interviews were conducted using a self-developed questionnaire in November 2022. Survey data were analysed using relative frequencies and bivariate logistic regression. Findings. Among all participants, 626/1020 reported internet use in health context and 278/626 (44%) reported digital technology use for PA promotion. Most of the 278 users for PA promotion reported that such technologies are easy to use (92%) and use them at least once a week (91%). The reasons for using digital technologies were to measure own PA (74%) or to find exercise ideas (57%). Most participants reported using mobile devices (e.g., smartphones, 77%, or activity trackers, 58%) and rated device feedback as helpful (69%). Among sociodemographic factors (age, gender, education, household income), health status and eHealth literacy, younger age was the only significant predictor (OR=.98, 95% CI: .97-.99) of digital technology use for PA promotion. Discussion. Despite their availability, the prevalence of digital technology use for PA promotion is still low among adult internet users in Germany. Such technologies are likely to support PA behaviour change because users rate them as easy to use, their feedback as helpful and use them frequently. Health interventions are necessary to encourage digital technology use for PA promotion among adults in Germany.

We aimed to assess the attitudes towards digital technology use in health context using a nationwide survey. Methods A cross-sectional nationwide survey of a panel sample of adult internet users living in Germany was conducted in November 2022. Participants completed computer-assisted telephone interviews using a self-developed, 30-item questionnaire. Survey data were analysed using frequencies and univariate multiple regression analysis. Findings Among 1,020 participants (18-92 years, 56±16 years, 47% female), 62% completed up to tertiary education and 42% reported the household income of up to 3500 Euro/month. The minority of participants reported that they trust health websites when recommended by friends and family (39%), that their social network relies on the internet for health information (35%), that they consider the internet as the immediate source of health information (39%) and that they are interested in digital health technologies (40%). Most participants (71%) reported that they prefer to receive health information in person or on paper. The preference for such sources of health information was associated with lower eHealth literacy (β= -.12, p<.001), worse health status (β= -.08, p=.026) and female gender (β= -.08, p=.033). Discussion The trust in the internet as the source of health information and the interest in digital health technologies were low among internet users in Germany. Interventions should strengthen eHealth literacy to empower adults to find, understand and assess reliable health information on the Internet.

Diese Studie untersucht die Zusammenhänge zwischen Ruralität, digitaler Gesundheitskompetenz und Interesse an digitalen Gesundheitstechnologien. Methoden Daten einer deutschlandweiten telefonischen Befragung Erwachsener zu Einstellung und Nutzung digitaler Gesundheitstechnologien wurden mit Ruralität (Einwohnerdichte/km²) verlinkt (n=941). Zusammenhänge zwischen digitaler Gesundheitskompetenz (eHEALS-Skala), Interesse an digitalen Gesundheitstechnologien (gering/hoch) und Ruralität wurden mit bi- und multivariaten Verfahren, adjustiert für Alter, Sozialstatus und Geschlecht analysiert. Ergebnisse Digitale Gesundheitskompetenz und Interesse an digitalen Gesundheitstechnologien sind im ländlichen Raum schwächer ausgeprägt als im urbanen Raum (t (877) =-3.13, p=.002, d =-.254; Chi² (1, N=936) =6.04, p=.014). Geringere Einwohnerdichte ist mit einer niedrigeren Gesundheitskompetenz (β=.07; p=.043) und mit weniger Interesse an digitalen Gesundheitstechnologien assoziiert (OR=1.21; 95%KI 1.084-1.352). Schlussfolgerung Bewohnende des ländlichen Raums unterscheiden sich hinsichtlich ihrer digitalen Gesundheitskompetenz und ihres Interesses an digitalen Gesundheitstechnologien von urbanen Regionen. Räumliche Faktoren sollten als mögliche Zugangsbarrieren bei der Implementierung digitaler Gesundheitstechnologien berücksichtigt werden.

Such sequential dependence has been extensively studied in the visual domain, but less is known about its impact on time perception. Moreover, there are ongoing debates about whether these sequential biases occur at the perceptual stage or during subsequent post-perceptual processing. Using functional magnetic resonance imaging, we investigated neural mechanisms underlying temporal sequential dependence and the role of action in time judgments across trials. Participants performed a timing task where they had to remember the duration of green coherent motion and were cued to either actively reproduce its duration or simply view it passively. We found that sequential biases in time perception were only evident when the preceding task involved active duration reproduction. Merely encoding a prior duration without reproduction failed to induce such biases. Neurally, we observed activation in networks associated with timing, such as striato-thalamo-cortical circuits, and performance monitoring networks, particularly when a “Response” trial was anticipated. Importantly, the hippocampus showed sensitivity to these sequential biases, and its activation negatively correlated with the individual’s sequential bias following active reproduction trials. These findings highlight the significant role of memory networks in shaping time-related sequential biases at the post-perceptual stages.

These devices might be a means to extend the scalability of integrated circuits since they allow for fast and nonvolatile operation. Unfortunately, large analog circuits need to be designed and integrated in order to benefit from these cells, hindering the implementation of large systems. This work elaborates on a novel solution, namely, creating digital standard cells utilizing RRAM devices. Albeit this approach can be used both for small gates and large macroblocks, we illustrate it for a 2T2R-cell. Since RRAM devices can be vertically stacked with transistors, this enables us to construct a nand standard cell, which merely consumes the area of two transistors. This leads to a 25% area reduction compared to an equivalent CMOS nand gate. We illustrate achievable area savings with a half-adder circuit and integrate this novel cell into a digital standard cell library. A synthesized RISC-V core using RRAM-based cells results in a 10.7% smaller area than the equivalent design using standard CMOS gates.

This study investigates the dispersion and stability of Ni nanolayers by grafting bifunctional groups over the hierarchical zeolite 13X (h13X) support using (3-aminopropyl)triethoxysilane (APTES). The Ni nanolayers, with a thickness of 1.5-7 nm, were deposited around the edges of h13X and analyzed using STEM imaging. A clear shift in the binding energies was observed by XPS analysis, substantiating the enhanced metalsupport interaction (MSI) between NiO and h13X. The influence of reaction temperature on APTES incorporation into h13X was revealed by H2-TPR and CO2-TPD, with notable variations in the reducibility and surface basicity profiles of the catalysts. The optimized catalyst exhibited CO2 conversion of 61% with CH4 selectivity of 97% under GHSV of 60,000 mlgCat-1h-1 at 400 oC and 1 bar and demonstrated robust stability over a period of 150 h without discernible degradation. The enhanced performance could be attributed to the strengthened MSI and reduced size of Ni nanolayers over h13X. These findings highlight the development of robust heterogeneous catalysts by changing the surface chemistry of support material for various catalytic applications.

In experiments using a local gas flow directed at the keyhole rear wall, a reduction in spatter formation on the specimen top side was observed for welding of AISI 304. However, the interaction between gas flow and keyhole behavior with respect to the mechanisms and locations of spatter detachment, especially on the bottom side, is not yet fully understood. High-speed synchrotron X-ray imaging enables detailed insights into the keyhole behavior and the spatter formation to obtain a deeper understanding of the underlying mechanisms. During the reference experiments welding without shielding gas flow, the spatter detach from a melt pool swelling behind the keyhole aperture on both sides of the sheet. A gas flow with a low flow rate of 4.8 L/min reduces the spatter formation on the top side and the keyhole length due to the absence of oxygen affecting the surface tension. A swelling also forms on the keyhole front on the bottom side and small spatter detach undirected. Increasing the flow rate to 12.8 L/min elongates the keyhole, particularly on the specimen top side. The increased momentum transfer of the gas flow results in a periodic keyhole oscillation on the specimen top side. In combination with an elongated melt pool, the oscillation is directly correlated with the hump formation, caused by melt being pushed over the already solidified weld seam. In addition, spatter does not detach from the top side due to the changed melt flow and only detach from the keyhole front on the bottom side.

However, it remains unclear how the role of social determinants of health (SDoH) and digital determinants of health (DDoH) plays in this context. Objective This study investigates differences in sociodemographic factors and digital health literacy between wearable users and non-users, whether the association with wearable use varies across age groups and its potential mediator. Methods A cross-sectional nationwide telephone survey was conducted in November 2022 in a panel of adult internet users in Germany. Assessments included self-reported wearable use, sociodemographic factors (sex, age, education, household size and income, and residence region), and digital health literacy (measured with the eHealth Literacy Scale, eHEALS). Associations between wearable use, sociodemographic factors and digital health literacy were analyzed using binomial logistic regression models in the total sample and with age group stratification, with a supplementary mediation analysis examining digital health literacy as a mediator in the relationship between age and wearable use. Results Overall, 24% (223/932) of participants (52% male, mean age 55.6 years) reported using wearables for health. Wearable use was lower among participants aged 65 and above, with lower educational attainment, living in 1–2 person households, with below-average household income, and residing in smaller cities or former East Germany. Wearable use prevalence is substantially lower in older age groups (18–40: 36%; 41–64: 26%; 65+:14%). Wearable users reported higher levels of digital health literacy (mean: 30.7, SD = 5) than non-users (mean: 28.3, SD = 6). Stratified analyses indicate that the association between digital health literacy and wearable use varies by age group, with significant positive association observed in older age groups (OR = 1.00, 95% CI: 0.94 to 1.07 in age group 18–40; OR = 1.07, 95% CI: 1.03 to 1.12 in age group 41–64; OR = 1.11, 95% CI: 1.04 to 1.19 in age group 65+). Mediation analysis indicated that digital health literacy partially mediates the relationship between age and wearable use (indirect effect: coefficient = -0.0156, 95% CI: -0.0244 to -0.00791, p <.001). Conclusions This study indicates sociodemographic disparities in wearable use among the German population and differences in digital health literacy between wearable users and non-users. A generational divide in wearable use was identified, with older adults being less likely to embrace this technology. This was especially true for older adults with lower digital health literacy. Future public health initiatives employing health technologies should take SDoH and DDoH into consideration to ensure effective and equitable impacts.

T1 - Wheat crop models underestimate drought stress in semi-arid and Mediterranean environments T2 - Field crops research N2 - Under climate change and increasingly extreme weather, projections of water demand and drought stress from process-based crop models can inform risk management and adaptation strategies. Previous studies investigating maize crop models demonstrated considerable error in the simulation of water use, and no similar evaluation of wheat crop models exists. The aims of this study were to (1) evaluate wheat crop models’ performance in reproducing observed daily evapotranspiration (ET) for Mediterranean and semi-arid environments, and (2) identify factors and processes associated with model error and uncertainty. These were assessed with an ensemble of wheat crop models for two experiments, one conducted in Bushland, Texas, USA (three seasons, deficit and full irrigation) and another in Avignon, France (four rainfed seasons) with winter bread and durum wheat, respectively. Models were calibrated with all observed data for crop growth. The model ensemble median underestimated water use in all environments evaluated, suggesting a systematic bias. The relative error in underestimating daily ET was constant across levels of atmospheric evaporative demand; therefore, the absolute error was greater for days with larger evaporative demand. This implies errors in the soil water balance increase more rapidly under high evaporative demand conditions. Using a potential versus reference crop evapotranspiration approach did not explain relative model performance. However, the sensitivity analysis indicated that simulation of atmospheric evaporative demand terms explained much more uncertainty in seasonal water use than terms related to soil depth or root growth. Errors in simulated leaf area index were associated with errors in daily simulated ET, but the relationship varied with the growth stage. Collectively, the results suggest the need to improve simulation of atmospheric ET demand to avoid underestimating projected impacts of drought or required water resource availability for viable production systems.

The experimental setup utilized a COHERENT HighLight FL8000-ARM fiber laser with concentric intensity distribution created by an optical fiber cable. The European Synchrotron Radiation Facility (ESRF, beamline ID19) was used to conduct high-speed synchrotron imaging at 20,000 images per second to study the spatio-temporal keyhole behavior. Keyhole geometries were extracted through advanced image processing techniques, allowing quantification of parameters like depth, aperture, bulging, and determination of related oscillation frequencies. The results showed that core-dominated processes exhibit significant variations in keyhole geometry. In contrast, ring-dominated processes exhibited reduced penetration depths but increased melt pool dynamics due to altered absorption conditions and increased temperatures within the melt pool. A stabilized core-ring power distribution minimized fluctuations, resulting in improved process stability. The findings were summarized in a model concept describing three characteristic keyhole regimes: core-dominated, ring-dominated, and stabilized core-ring processes.

Such a decision surface has a good classification ability for unknown new samples. In real-world applications, the data set usually contains many noises and outliers, which will affect the learning of the decision surface, thus the maximum margin cannot be obtained, and the generalization ability of SVM will be reduced. In this paper, we introduce an adjacency factor to each input point to characterize the local neighbor relationship between each point. Weighting each sample point by the adjacency factor can let different sample points make different contributions to the learning of the decision surface. Thus, we can filter out the influence of noises and outliers on the decision surface by this weighting method. We propose this new method namely local neighborhood reliability weighted support vector machine (LN-SVM).
