Hierarchical quasiparticle dynamics in antiferromagnets revealed by time- and momentum-resolved X-ray scattering

Abstract Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations —magnons— mediate these flows in ultrafast magnetism. Yet momentum-resolved access to low-energy magnons governing the microsc...

Laser‐Generated CuPdAgPtAu High‐Entropy Alloy Nanoparticles—Thermal Segregation Threshold and Elemental Segregation

ABSTRACT In this study, noble metal HEA NPs (CuPdAgPtAu) are produced from equimolar and Cu‐ or Ag‐enriched bulk targets via laser ablation in liquids, with structural and compositional analyses by advanced electron microscopy and XRD, complemented by atomistic simulations. Equim...

Phylogeny of Mastigitae sheds light on a hundred‐million‐year‐long morphological stasis of the extant genus Clidicus Laporte (Coleoptera: Staphylinidae: Scydmaeninae)

Mastigitae comprise 15 genera, of which seven are extinct, and species of two extant genera are also documented as fossils. The rich fossil record makes Mastigitae exceptional among Staphylinidae. Based on results of phylogenetic analyses comprising 33 extant species, 10 dated fo...

Evaluating zinc bioavailability in dredged sediments of Guanabara bay (BRAZIL): implications for coastal management standards

Abstract Guanabara Bay (GB) is an environment contaminated by metals, and it is the bay that receives the most dredging in Brazil and South America. Previous studies have shown the impact of dredging on planktonic and benthic species, which were not correctly measured by the Braz...

AI as the New Paint: A Systematic Review of AI as a Design Material

Artificial intelligence (AI) is increasingly influencing creative practice and workflows, with growing research exploring how it can be applied to advance creative work. In parallel, scholars have begun conceptualizing AI as a design material that practitioners can actively shape...

Counterion-Dependent Charge Transport in Ultrathin-Film Molecular Junctions

Abstract Counterions are ubiquitous in charged molecular films, yet their influence on charge transport in solid-state molecular junctions (MJs) remains insufficiently understood. Here, we investigate how embedded counterions regulate conductance in MJs based on ultrathin molecul...

Multi-GNSS clock combination for PPP with an epoch-wise clock alignment and variance component estimation

Abstract Applications of Global Navigation Satellite Systems (GNSS) for positioning, navigation, and timing rely on precise orbit and satellite clock corrections provided by multiple Analysis Centers (ACs) of the International GNSS Service (IGS). To address modeling errors and da...

Microbial metabolite p-cresol associates with constipation in adults with high-functioning autism spectrum disorder and induces constipation-like symptoms in mice

Abstract Gastrointestinal (GI) symptoms are prevalent in Autism Spectrum Disorder (ASD), yet their biological correlates remain poorly understood, notably in adults. The microbiota-derived metabolite p- cresol is reported to be elevated in the urine and stool of ASD patients, but...

Soft-Templated Carbon Models Elucidate the Anomalous Increase of Capacitance in Nanopores

Abstract Supercapacitors are electrochemical energy-storage devices distinguished by rapid charge–discharge and high power density. The observation of anomalously enhanced capacitance in nanoporous carbons challenged classical descriptions of double-layer charging and stimulated...

Chaperone-inspired nanobodies enable pathway-selective control of Tau self-assembly

Abstract Selective control of pathogenic protein self-assembly remains a major challenge for intrinsically disordered amyloid-forming proteins such as Tau. Here we show that nanobodies originally raised against the chaperone S100B unexpectedly cross-react with Tau as potential pa...

From Versioned Cities to Versioned Documents: Extending CityRDF for Modelling Urban Documentation over Time

Cities are documented by large and heterogeneous multimedia corpora, including photographs, maps, plans, reports, videos, and web resources. While versioned urban models have been studied for representing the temporal evolution of city objects, the documents describing these obje...

On well-posedness for second-order degenerate parabolic equations with unbounded lower-order terms

Abstract In this paper, we establish the well-posedness of Cauchy problems for weak solutions to second-order degenerate parabolic equations with a non-smooth, time-dependent degenerate elliptic part that includes both bounded and unbounded lower-order terms. The unbounded lower-...

Stem-cell modeling of cerebellar dysfunction of Angelman syndrome

Angelman syndrome is a severe neurodevelopmental disorder caused by loss of function of the maternal allele of the neuron-specific imprinted gene UBE3A. Although Angelman syndrome presents with developmental delay, ataxia, epilepsy, and speech impairment, the contribution of spec...

Stepwise evolution of the developmental and symbiotic functions of DELLA in land plants

Summary DELLA proteins play diverse roles in development, plant-microbe interactions and stress responses, and are regulated by the hormone gibberellic acid (GA) in flowering plants. Here, we investigated the evolutionary conservation of functions of the single DELLA ortholog in...

BRET-Based Mitochondrial Subcompartment Localization Biosensors Reveal the Impact of Pesticides and Food Additives on Mitochondrial Protein Localization

Abstract The last decade has witnessed a marked increase in interest in mitochondria, whose dysfunction leads to the development of multiple diseases. Mitochondria are unique as they are highly compartmentalized organelles that are composed of two closely apposed membranes. Here,...

A Numerical Study on the Sensitivity of DAS and Geophone Signals to a Thin CO2 Plume

ABSTRACT One of the main concerns in monitoring during a CCUS (carbon capture, utilization, and storage) project is the detectability of changes in petrophysical properties induced by the substitution of the initial fluids by . Seismic attributes are thought to have the potential...

Uncovering the cytotoxicity and growth inhibition of 14 Microcystis extracts on freshwater fish cell lines

Freshwater cyanobacteria raise health and ecotoxicological concerns due to their production of secondary metabolites. The Microcystis genus synthesizes the well-known cyanotoxins, microcystins (MCs), but also various metabolites with documented sublethal and lethal effects. The t...

Decoupling the Role of Nanoparticle Rigidity and Chemistry in Particle Transport through the Brain Parenchyma

Abstract Drug delivery to the brain involves challenging transportation across multiple biological barriers. Despite the great tunability of polymeric nanoparticles, the synthetic challenge of varying the physical property of a nanoparticle without varying its chemical formulatio...

Supramolecular Janus Nanocylinders: Solvent-Induced Hydrogen-Bond Modulation Yields Structures under Thermodynamic Equilibrium

Abstract Janus nanocylinders (JNCs) are anisotropic, non-centrosymmetric colloids composed of two different faces, making them attractive for advanced functional materials. However, their nanometric dimensions and pronounced anisotropy complexify their preparation. Recently, a ve...
