AbstractA comb‐like polyacrylic superdispersant (CPS) consisting of polyacrylic acid‐co‐poly(isobutyl alcohol polyoxyethylene ether) (PBAT) was synthesized as a dispersant for preparing nano‐calcium carbonate/PBAT (nano‐CaCO3/PBAT) composite through internal mixing. Chemical structure analysis revealed that CPS adsorbed onto the surface of nano‐CaCO3 via coordination between carboxyl groups and calcium ions, effectively dispersing particles using a comb‐shaped side chain and electrostatic repulsion. This improved compatibility between nano‐CaCO3 and PBAT resulted in enhanced crystallinity, tensile stress, and elongation at break. By incorporating only 0.4 wt% CPS into 10 wt% nano‐CaCO3 (based on PBAT weight), the dispersion of nano‐CaCO3 was significantly improved, leading to a superior two‐phase interface in the composite material. Consequently (in the film's machine direction), elongation at break increased from 882 ± 49% to 1047 ± 31%, while tensile strength increased from 22.10 ± 2.06 MPa to 26.70 ± 1.14 MPa. These findings facilitate the production of high‐performance PBAT composites suitable for blow molding into biodegradable films.Highlights

AbstractA novel core‐shell continuous polymeric fiber reinforced composite with excellent mechanical performance was prepared using a dual‐extrusion process. Continuous pumping of a thermotropic liquid crystalline polymer (TLCP) into polyamide 6 (PA6) via dual‐extrusion equipped with a core‐shell circular die enabled the generation of continuous fiber reinforced composite filaments with core‐shell structure. Microscopic analysis confirmed the composition of the composite and the core‐shell macroscopic morphology where the TLCP core was surrounded by a polyamide shell. The core‐shell structure exhibited a strong weld‐strength of 3D printed parts with improved tensile properties which was attributed to the strong inter‐diffusion and entanglement of polyamide chains across the printed layers. The average tensile strength of 3D printed core‐shell TLCP‐polyamide material was measured to be 132.7 MPa, which is an improvement of about 50% compared to its “sea‐island” TLCP‐polyamide counterparts prepared using the same dual extrusion process with added static mixers. A comparison between the printed core‐shell 20 wt% TLCP‐PA6 and continuous traditional glass‐fiber reinforced composite revealed that the printed core‐shell 20 wt% TLCP‐PA6 exhibited a tensile modulus (~12 GPa) approximately 300% higher than that of its 20 wt% glass‐fiber/polyamide counterpart. The continuous TLCP composite filament can be printed with a generic extrusion‐based 3D printer without requiring any modification, and the presence of continuous TLCP fibers in the filament core has no adverse effect on the printability. Notably, sharp turns (e.g., 180° changes in printing direction) can be achieved during the printing without creating fiber‐less regions in the printed parts which overcomes one of the major limitations of printing continuous glass or carbon‐fiber reinforced composites. By leveraging the core‐shell morphology with TLCP's lightweight and reinforcement properties, we successfully fabricated high strength and stiff additively manufactured parts with enhanced interlayer bonding.Highlights

Published: December 2024

AbstractBased on the microstructure of PFPC, this article proposes a grading construction model that conforms to the normal distribution law by observing the distribution characteristics of the particles. A RVE random placement modeling program is developed using Python language, and an RVE model containing irregular polygonal particles is constructed, providing an effective new method for microfinite element modeling of PFPC. The validity of the model is proved by comparing the simulation results of the composites stress–strain behavior and the experimental results. The effects of particle volume fraction and particle size distribution on crack extension are analyzed using this microfinite element model, and their influence on the fracture properties of the composites is discussed. The results show that the initiation location and propagation direction of cracks in the material are influenced by the particle size, size distribution, and loading conditions. With the increase of particle volume content, the fracture properties of particles increase first and then decreased. When the volume fraction of particles is certain, the fracture property decreases with the increase of the mean value of particle size. The fracture properties of the composites can be improved by regulating the combination of particles with appropriate SD of particle size.Highlights

Published: December 2024

AbstractThe Inland Pacific Northwest is the largest Kentucky bluegrass (Poa pratensis L.) seed production area worldwide. Historically, farmers in Washington burnt Kentucky bluegrass residues, a common practice for pathogen control, pest management and maximum economic revenue. Washington State implements air quality and fire safety burn bans under certain conditions to protect public health and safety. Outside of Native American reservations, burning of Kentucky bluegrass has been outlawed in Washington state, which raised the need for breeding a new Kentucky bluegrass cultivar that will have good yield without burning. ‘Matchless’ (Reg. no. CV‐102, PI 701401, PVP 202200523) Kentucky bluegrass is a common‐type cultivar released in 2023. Matchless was selected for its superior yield without burning crop residues, derived from the common‐type cultivar ‘Kenblue’, in an open‐pollinated nursery in Pullman, WA. Matchless was compared to Kenblue, ‘America’, ‘Baron’, and other standard cultivars, and exhibited taller plant height, longer leaf sheath length, and longer panicle length, among other traits. Matchless outperformed Kenblue in turf quality and exhibited similar spring green‐up. The combination of statistically significant differences in traits makes Matchless a unique cultivar. It is distinct from its parental cultivar Kenblue and other common‐type cultivars and performs and adapts well for use in home lawns, parks, and reclamation projects.

AbstractBackgroundThe Borderline Personality Features Scale for Children (BPFSC‐11) is a well‐used, short, and easy‐to‐administer measure of borderline traits in young people. The aim of the current study was to evaluate the psychometric properties of the Mexican Spanish version of the BPFSC‐11 in a large community‐based sample of Mexican adolescents. In addition, we evaluated the convergence between the borderline construct as measured by the BPFSC‐11 and general personality functioning consistent with more contemporary personality disorder formulations to assess the nomological net of the BPFSC‐11 total score.MethodsA sample of 1212 adolescents (52.6% female, mean age = 15.11, SD = 1.74) were recruited from the community through schools in Mexico City and Michoacán area.ResultsReliability of the BPFSC‐11 was good (α = 0.805; ω = 0.806). A confirmatory factor analysis (CFA) model testing the unidimensional factor structure of the 11 items of the BPFSC‐11 provided good fit (X2[44] = 137.96, p < 0.001; root mean square error of approximation (RMSEA) = 0.04 [90% CI: 0.03, 0.05]; comparative fit index (CFI) = 0.96; standardized root mean square residual (SRMR) = 0.03). Both configural and metric invariance for gender and age were demonstrated; however, only partial scalar invariance could be demonstrated with some items showing “bias” for gender and age. The Mexican Spanish BPFSC‐11 also showed strong convergence with measures assessing contemporary conceptualization of general personality functioning.ConclusionsThe Mexican Spanish BPFSC‐11 appears to show similarly strong psychometric properties of other versions of the BPFSC‐11; and the borderline construct as assessed with the BPFSC‐11 shows good conversion with general personality functioning in adolescents.

Published: December 2024

AbstractResearch SummaryThis work explores the intersection of strategic entrepreneurship and craft‐based ventures, focusing on the integration of materiality, authenticity, and tradition in the creation of competitive advantage. Craft, historically rooted in artisanal, small‐scale production, has evolved into “advanced craft,” requiring high expertise while also engaging with modern economic goals such as scaling, technological adoption, and global value chains. Craft‐based strategic entrepreneurship embraces creativity and innovation, alongside traditional values and high‐quality production, to engage with the modern economy without the alienating effects of industrialization. We highlight how craft entrepreneurs balance the pursuit of innovation with the preservation of authenticity and heritage. By examining the materiality, authenticity, and tradition embedded in craft, our work contributes to the understanding of how these elements influence competitive advantage and the broader relationship between economy and society in entrepreneurial ventures.Managerial SummaryWe offer practical insights for owners and managers in craft‐based ventures seeking to balance tradition with modern business strategies. As the craft sector evolves into “advanced craft,” entrepreneurs must integrate artisanal expertise with scalable operations, technology adoption, and global market engagement. We highlight how successful craft ventures maintain high quality, authenticity, and cultural heritage while embracing strategic entrepreneurship practices like innovation, planning, and partnerships with larger organizations. For owners and managers, the key takeaway is the importance of preserving the unique values of craftsmanship—such as materiality, authenticity, and tradition—while also adopting modern tools like advanced technology and marketing strategies to scale and compete. By understanding these dynamics, craft‐based businesses can enhance their competitive advantage, foster meaningful customer engagement, and navigate challenges like technological disruption and market expansion without losing their core identity.

AbstractThe alpine biome, above the natural tree line, is home to distinctive biotas that can tolerate harsh environmental conditions, and is especially sensitive to the impacts of global warming. However, the actual timeframe during which alpine floras began to appear on a global scale remains unknown. Here, we used Anemone (c. 200 species), an herbaceous plant genus inhabiting a variety of habitats from lowland to high‐alpine zone across multiple continents, to obtain new insights into the historical assembly of this biome. Using nuclear ITS and plastid atpB‐rbcL, trnL‐F, matK, and rbcL sequences, we built a phylogeny that includes 159 individuals of 146 extant Anemone species and 19 outgroups. Within this phylogenetic framework, we estimated divergence times, reconstructed ancestral ranges, and inferred the evolutionary shifts in habitat types. Phylogenetic analyses strongly support the non‐monophyletic Anemone, in which the Clematis‐Anemoclema clade is nested. Two subgenera of Anemone, subg. Anemone and subg. Anemonidium, are strongly supported as monophyletic. Except for Anemone sect. Keiskea, whose Anemone deltoidea is grouped with A. sect. Hepatica, the other seven sections of this genus are monophyletic. Anemone originated in East Asian non‐alpine habitats around 31 Ma, but range expansion and habitat shifts from non‐alpine to alpine mainly occurred after the Miocene Climatic Optimum (c. 14 Ma). The alpine Anemone lineages in different biogeographic regions originated near‐synchronously, beginning in the middle Miocene (c. 16–12 Ma). We also found that the other alpine floristic elements across multiple continents emerged roughly at the same time. Our findings suggest that the rise of global alpine floras is near‐synchronous and began in the middle Miocene, possibly in association with the mid‐Miocene global cooling and regional orogenetic activities. The mid‐late Miocene is an essential period for the assembly and evolution of global alpine floras. The alpine floristic diversity comprises pre‐adapted immigrants from other alpine zones through long‐distance dispersal and descendants from local lowland ancestors, as well as from other regional lowland ancestors to a lesser extent.

Published: December 2024

ABSTRACTThe global decline of species necessitates intensive conservation efforts, including ex‐situ breeding programs to safeguard endangered populations. However, managing welfare and reproduction in zoological gardens can present several challenges. This study aims to explore behaviors and endocrinological responses of two specimens of fossa (Cryptoprocta ferox) under human care. One hundred and twenty hours of observation through focal animal sampling continuous recording and 67 fecal samples were collected. From fecal samples, cortisol (FCM), progesterone (FPM), and testosterone (FTM) metabolites' concentrations were analyzed using Radio Immuno Assay. According to our results, higher FTM (p < 0.05) and FPM levels at the beginning of the study, showing a potential alignment with the breeding season. When the male entered the female outdoor area, he recorded longer durations of seeking and marking behaviors (p ≤ 0.01), along with lower FCM levels (p < 0.05), suggesting an enriching effect. In the same period, the female's FCM level was higher (p ≤ 0.01), indicating potential stress. When both animals were in their respective outdoor areas, the FCM level of the female remained significantly higher (p < 0.05), and the male showed a peak in pacing duration (p < 0.01), implying a potential stress or frustration status. In her indoor area, the female exhibited significantly shorter durations of locomotion, marking, and seeking (p < 0.01) and did not show any abnormal behavior, likely due to the reduced complexity of the environment. However, we cannot exclude that her complete visual and olfactory separation from the male and visitors may also have contributed to a decrease in her overall stress levels. The findings highlight the interplay between hormonal fluctuations and behavioral responses in the two zoo‐housed fossa, providing essential insights for fostering their well‐being and facilitating conservation efforts.
Multi-centered Dilatations, Congruent Isomorphisms and Rost Double Deformation Space
Authors: Mayeux Arnaud 
Published: December 2024

AbstractWe introduce multi-centered dilatations of rings, schemes and algebraic spaces, a basic algebraic concept. Dilatations of schemes endowed with a structure (e.g., monoid, group or Lie algebra) are in favorable cases schemes endowed with the same structure. As applications, we use our new formalism to contribute to the understanding of mono-centered dilatations, to formulate and deduce some multi-centered congruent isomorphisms and to interpret Rost double deformation space as a double-centered dilatation.

Abstract
Progress in developing therapies for the maintenance of endogenous insulin secretion in, or the prevention of, type 1 diabetes has been hindered by limited animal models, the length and cost of clinical trials, difficulties in identifying individuals who will progress faster to a clinical diagnosis of type 1 diabetes, and heterogeneous clinical responses in intervention trials. Classic placebo-controlled intervention trials often include monotherapies, broad participant populations and extended follow-up periods focused on clinical endpoints. While this approach remains the ‘gold standard’ of clinical research, efforts are underway to implement new approaches harnessing the power of artificial intelligence and machine learning to accelerate drug discovery and efficacy testing. Here, we review emerging approaches for repurposing agents used to treat diseases that share pathogenic pathways with type 1 diabetes and selecting synergistic combinations of drugs to maximise therapeutic efficacy. We discuss how emerging multi-omics technologies, including analysis of antigen processing and presentation to adaptive immune cells, may lead to the discovery of novel biomarkers and subsequent translation into antigen-specific immunotherapies. We also discuss the potential for using artificial intelligence to create ‘digital twin’ models that enable rapid in silico testing of personalised agents as well as dose determination. To conclude, we discuss some limitations of artificial intelligence and machine learning, including issues pertaining to model interpretability and bias, as well as the continued need for validation studies via confirmatory intervention trials.

Using coupled bulk-rock geochemistry and short-wave infrared (SWIR) spectral reflectance data as rapid exploration tools in metamorphosed VHMS deposits: insights from the King Zn deposit, Yilgarn Craton, Western Australia

AbstractBulk rock geochemistry and SWIR reflectance spectroscopy are widely used by companies for rapid and cost-effective exploration of volcanic-hosted massive sulfide (VHMS) deposits. However, few studies have integrated bulk-rock geochemistry with hyperspectral reflectance spectroscopy in greenstone belts that have undergone high-grade metamorphism. Here we present an extensive dataset combining bulk-rock geochemistry with chlorite and white mica SWIR spectral reflectance from the amphibolite-grade King VHMS deposit of the Yilgarn Craton, Western Australia. At King, the footwall stratigraphy is dominated by tholeiitic mafic rocks overlain by a sequence of calc-alkaline intermediate-felsic metavolcanic rocks. The hanging-wall stratigraphy is characterized by a thin metaexhalite layer, overlain by thick succession of interbedded metasedimentary and metavolcanic rocks. Chlorite spectral signatures are more Fe-rich in mafic lithologies and Mg-rich in felsic rocks, particularly where intense Mg-metasomatism occurred before metamorphism. In all units, Fe/Mg ratios of chlorite are strongly tied to bulk rock Fe/Mg ratios. White mica in the footwall is primarily muscovitic, with minor amounts of phengite in deep Fe-rich mafic rocks. By contrast, the hanging-wall sequence is dominated by phengitic signatures in both the Fe-rich metaexhalite, and weakly Ca-Mg altered volcanic rocks. This study concludes that chlorite SWIR reflectance is largely influenced by the bulk Fe/Mg composition of the host rock, whereas white mica reflectance correlates with the type and intensity of hydrothermal alteration prior to metamorphism. These findings underscore the potential of using chlorite and white mica spectral signatures to understand hydrothermal alteration patterns and detect new orebodies in metamorphosed VHMS systems.
