Sensitivity of neutrino oscillations to the Earth’s interior properties

Understanding the Earth’s deep interior remains challenging, as traditional geophysical methods face ambiguities in linking seismic observations to temperature, composition, or mass density variations. Atmospheric neutrinos, produced by the constant flux of cosmic rays colliding...

The Molecular Origin of Perylene Fluorescence in Gas, Solution and Crystal Phases: A Comparative Theoretical Study

Abstract Perylene is a widespread molecular motif in materials science thanks to its phase-dependent optical response and its good excitation transport properties, making it ideal for many optoelectronic applications. However, the molecular-level understanding of how changing the...

Arrival-Time Distributions as a Probe of the Preferred Foliation in Relativistic Bohmian Mechanics

Relativistic extensions of de Broglie–Bohm theory postulate a preferred foliation of spacetime, an additional structure essential for defining simultaneous configurations on Minkowski spacetime but conventionally believed to be empirically undetectable at quantum equilibrium. In...

Intra- and inter-specific variability in benthic foraminifera modulates surface sediment reworking

Abstract Bioturbation is a key ecological process that regulates benthic ecosystem functioning, including organic matter remineralization and nutrient regeneration. Despite growing evidence that meiofauna, and benthic foraminifera in particular, contribute to sediment bioturbatio...

NetSyn: prokaryotic genomic context exploration of protein families

Background . The growing availability of large prokaryotic genomic datasets presents an opportunity to discover new metabolic pathways and enzymatic reactions useful for industrial or synthetic biological applications. Efforts to identify new enzyme functions in this vast number...

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...

Wall-crossing phenomenon for the liquid bin model

We introduce the liquid bin model as a continuous-time deterministic dynamics, arising as the hydrodynamic limit of a discrete-time stochastic interacting particle system called the infinite bin model. For the liquid bin model, we prove the existence and uniqueness of a stationar...

A Novel Striated Membrane Contact Site in Vestibular Hair Cells

The mammalian vestibular system has two types of sensory receptor hair cells (HCs), each with different neurotransmission mechanisms. Type II HCs use ribbon synapses to transmit neurotransmitters like glutamate to bouton terminals of afferent neurons. Type I HCs are nearly engulf...

Unlocking the Full Potential of Taylor Dispersion Analysis Through Advanced Detection

Today, pharmaceutical sciences rely on a wide range of innovative therapeutics of varying sizes: nanoparticles, proteins, antibodies, and nanocarriers for drug delivery. Measuring their size is one of the crucial parameters in their characterization, to ensure drug safety, stabil...

Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes

ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are widely used to image intracellular environments. Here we report donor–acceptor dyads based on the BODIPY chromophore in which PET is selectively activated upon hydration. Replacing fluorine groups at bo...

Inferring the perennial biomass and phytoremediation potential of thirty-one woody species from large phytomanagement field trials

Growing woody biomass on trace element-contaminated marginal lands is a promising phytomanagement strategy, provided that species combine high productivity with appropriate contaminant accumulation profiles. In this study, we evaluated the five-year field performance and phytoman...

Comprehensive profiling of brain dynamics during anesthesia across phylogeny

Abstract The behavioral effects of anesthetics are highly conserved across species, hinting at shared and fundamental underlying mechanisms. Here we compile a dataset of multiscale neural activity during wakefulness and anesthesia, encompassing human, macaque, marmoset, mouse, ze...

Metric and spectral aspects of random complex divisors

For any integer n\geq 2 , we prove that for any large enough integer d , with large probability the injectivity radius of a random degree d complex hypersurface in \mathbb{C}P^{n} is larger than {d^{-(n+2)/2}} . Here the hypersurface is endowed with the restriction of the ambient...

Arid grown coriander essential oil and linalool: effects of microencapsulation on the control of Staphylococcus aureus in minced sheep meat

Natural preservation strategies using essential oils are gaining momentum, but their volatility and reactivity limit their application in complex food systems where pathogenic bacteria like Staphylococcus aureus remain a persistent challenge. This study addresses this gap by firs...

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...

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...

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...

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...
