Size-dependent mechanical properties of cellulose-based materials: Experiments and theoretical model

Size is an important trait among marine phytoplankton as it influences a vast range of physiological, ecological, and evolutionary processes. For Trichodesmium, a cyanobacterial diazotroph important for the global nitrogen cycle, size is a flexible trait that can change because of its ability to form colonies. Trichodesmium colonies can persist from 10µm to greater than 1mm in the natural environment. Despite this known ability, we still do not know whether a maximum size limit exists for Trichodesmium colonies and, more importantly, whether any mechanisms regulate this limit. In this paper, we use a theoretical metabolic model to investigate the role of two factors known to influence Trichodesmium colony size: carbon dioxide and light availability. The greater the availability of carbon dioxide or the average light availability, the greater the potential colony size of Trichodesmium. Carbon limitations have a much stronger effect on colony sizes than light limitations. Higher respiratory costs, perhaps due to higher water temperatures, do not appear to limit maximum colony sizes unless they consume nearly all the carbon that is fixed. Our theoretical model highlights several scenarios that likely assert some control over the ecology of Trichodesmium in the global ocean. It also implies that natural colonies must have mechanisms to escape from carbon limitations. To achieve sizes like 1mm, Trichodesmium colonies must be highly porous (>91%) or live in environments with a nutrient flux 12 times greater than what molecular diffusion can provide.

Dust concentration distribution and variation in multi-level high ore passes during ore discharge

Autistic people's minority status makes them more vulnerable to minority stressors, such as stigmatization and victimization, which are linked to greater stress and lower life satisfaction. The Psychological Mediation Framework (PMF) proposes that cognitive, affective, and social-psychological processes help explain the relationships between these stressors and adverse outcomes. This cross-sectional study tested the PMF in autistic adults by examining how two of its key processes, internalized stigma and loneliness, are associated with stress and life satisfaction. Using self-report survey data from 831 autistic participants enrolled in the Netherlands Autism Register (NAR), aged 18-87 years (Mage = 47.5; SD = 12.5; 408 women, 309 men, and 114 gender-diverse individuals), multiple regression analyses showed that internalized autism-related stigma, emotional loneliness, and social loneliness were each positively associated with stress and negatively associated with life satisfaction. Mediation analyses indicated that both types of loneliness partially mediated the relationship between internalized autism-related stigma and these outcomes. Supporting the PMF, the findings suggest that autism-related stigmas may become internalized and be associated with loneliness, which is linked to greater stress and lower life satisfaction. Future studies should build upon the PMF and explore strategies to mitigate underlying minority stressors.Lay AbstractUnderstanding stress and life satisfaction in autistic adults with the psychological mediation frameworkWhy was this study done?Autistic adults often experience higher levels of stress and lower life satisfaction than non-autistic adults. Recently, research has suggested that these experiences are linked to them being part of a minority group-autistic people. Minorities often experience extra stress from experiences like stigma, sometimes called minority stressors. A theoretical model, the Psychological Mediation Framework (PMF), describes how minority stressors are linked to differences in people's thoughts, emotions, and feelings. This study examined whether the PMF can also help explain the stress and life satisfaction of autistic adults. We did this by testing whether two important parts of the PMF, internalized autism-related stigma (negative beliefs about being autistic) and loneliness, were linked to their stress and life satisfaction (how content people feel with their lives overall).What did we do?We analyzed data from 831 autistic adults who filled out a survey. In our statistical models (mathematical analyses that test how variables are related), we took into account other factors that are more commonly used to examine which factors were statistically associated with stress and life satisfaction in autistic adults, such as the level of characteristics related to autism and education level. By doing this, we increased the chance that any relationships we found could be attributed to minority stressors.What did we find?Autistic adults who experienced more internalized autism-related stigma, emotional loneliness (feeling disconnected from close relationships), and social loneliness (lacking a broader social network) reported higher stress levels and lower life satisfaction. We also found that autistic adults with more internalized stigma felt lonelier, and this loneliness was linked to higher stress and lower life satisfaction.What do the findings mean?The results suggest that autistic adults may internalize autism-related stigmas, which are linked to greater loneliness, higher stress, and lower life satisfaction. As these findings align with the PMF, we believe future studies should continue using this model. Also, we recommend that researchers should study ways to reduce minority stressors and improve the mental health of autistic adults.

Ultra-thin and ultra-lightweight meta-panel for low-frequency broadband sound insulation based on a computationally efficient design framework

Concrete-filled pultruded glass fibre-reinforced polymer (GFRP) box beams are innovative structural members with superior corrosion resistance and flexural capacity. However, GFRP profiles are vulnerable to thermal degradation at elevated temperatures, potentially compromising structural integrity. This study experimentally investigates the flexural behaviour of concrete-filled pultruded GFRP box beams after exposure to elevated temperatures to evaluate the fire resistance effects of the infilled concrete. Residual material properties of GFRP profiles were first studied by 88 groups of coupons subjected to temperatures from 50 to 350 °C (25 °C increments) for 15–60 min (15 min increments). A logistic-function-based theoretical model was then proposed to predict residual tensile and compressive strength. Subsequently, four-point bending tests were performed on hollow and concrete-filled GFRP box beams after exposure to temperatures of 250, 300 and 350 °C for various durations. The experimental results revealed that the flexural behaviour of the hollow GFRP box beams deteriorated significantly after being exposed to temperatures exceeding T g , with the flexural capacity decreasing by 65% at 350 °C after 60 min exposure. In contrast, the infilled concrete remarkably enhances the fire resistance of the GFRP box beams due to the isolation effect from direct air exposure, resulting in only minor reductions in flexural capacity and stiffness after heating. Finally, a residual flexural capacity prediction model of the beams was proposed and showed good agreement with experimental results. • A comprehensive experimental program examined GFRP material degradation at 50–350 °C. • A logistic-model-based approach was proposed to predict residual tensile and compressive strengths. • Ten hollow and concrete-filled GFRP box beams were tested in four-point bending after heating. • Concrete infill provided strong thermal protection, retaining flexural capacity even at 350 °C. • A practical flexural capacity prediction model was developed for fire-damaged GFRP box beams

We developed the integrated model of teacher's attention to examine teachers' a) situation awareness of the overall classroom and b) professional vision of individual pupils. Using mobile eye tracking in real classrooms, we analyzed teachers' eye movements using a novel metric, the Gaze Relational Index. The findings indicated that situation awareness involves shorter and more frequent gazes, while professional vision requires fewer but longer gazes. Experienced teachers showed faster and more varying visual attention compared to student teachers. This study provides valuable insights into visual processing in real-life classrooms, addressing the gap left by previous studies. • The teachers' gaze patterns varied when focusing on class versus individual pupils. • Experienced teachers showed faster visual processing than student teachers. • Experienced teachers vary their focus on individual pupils more than student teachers. • A theoretical and methodological integrated model of teacher's attention was created. • Mobile eye tracking and the Gaze Relational Index were used for real-life settings.

Surface properties of liquid alkali and alkaline earth metals: A theoretical and simulation approach

We explore the weak-field phenomenology of a compact star spacetime modified by quantum gravitational corrections derived from the effective field theoretical (EFT) approach by Calmet et al. [1]. These corrections, encoded in non-local curvature-squared terms, distinguish matter-supported geometries from vacuum solutions by contributing nontrivial modifications at order O ( G 2 ). Using the corrected metric, we analytically derive expressions for the deflection of light and time-like particles via the Gauss-Bonnet theorem. We further compute the perihelion advance of Mercury, Shapiro time delay, and gravitational redshift within this framework. Each classical observable acquires quantum corrections that, though exceedingly small (on the order of 10 − 9 arcsecond per century for perihelion precession and 10 − 18 arcsecond for light deflection) represent potential imprints of quantum gravity. The Shapiro delay and redshift likewise exhibit finite, source-dependent deviations from their general relativistic predictions due to the modified temporal metric component. While current observational capabilities remain insufficient to detect these minute effects, the analysis demonstrates that quantum gravitational signatures are embedded even in weak-field observables. Last, we study massless scalar perturbations in static, spherically symmetric spacetimes by analyzing their quasinormal modes (QNMs) and greybody factors using the WKB method and Pade resummation. Our findings demonstrate that increasing the coupling parameter enhances spacetime stability and significantly influences emission spectra through frequency-dependent transparency. Moreover, the results underscore that quantum-corrected star metrics yield phenomenological distinctions from classical black holes, particularly near the Planck scale, where vacuum solutions lose validity.
