Composition determination of biodiesel/ethanol blends using dielectric spectroscopy and tabular prior-data fitted networks

Biodiesel/ethanol blends represent a promising alternative to reduce the consumption of fossil diesel. This work employs frequency-domain dielectric spectroscopy to determine the permittivity of biodiesel/ethanol blends across the full range of compositions, at temperatures betwe...

Schizophrenia research in 2026: report from the annual meeting of the Schizophrenia International Research Society

Abstract SIRS 2026, held under the theme “Schizophrenia Research in the Era of Artificial Intelligence,” brought together researchers, clinicians, and persons with lived experience to take stock of a field whose tools for measuring, predicting, and intervening in psychosis have e...

Airflows redefine the cost of aerial transport in the wild

Fuel economy matters to both animals and machines, as the cost of transport can determine where, when, and how far locomotion is possible. However, established estimates of these values for animal flight come from laboratories and treat the atmosphere as constant, even though fre...

Diversionary feeding reshapes primate movement and reduces bark-stripping in pine plantations

Bark-stripping by wildlife in commercial tree plantations is a widespread management challenge that causes substantial economic losses and can create tensions between production and conservation goals. Effective mitigation has been hindered by limited understanding of the ecologi...

Weaker Coherence, Weaker Reciprocity: Comparing the Semantic and Social Organization of Moltbook and Reddit

Large language models enable the creation of autonomous agents that interact in social environments, raising the question of whether agent-based platforms reproduce the organizational properties of human social networks. We compare Moltbook, a social network populated by AI agent...

Some Fundamental Problems of Cosmology Among the Moqoit of the Chaco

ABSTRACT Indigenous cosmologies are frequently portrayed in anecdotal and superficial terms, a tendency that exoticizes them and frames them as products of irrationality or as beliefs. Such perspectives obscure the profound intellectual efforts these cosmologies represent—attempt...

Does EQ-5D measure the most relevant aspects of health across cultures? Findings from a multi-country qualitative and card-sorting study

The EQ-5D is a widely used measure of health-related quality of life (HRQoL) in health services and economic evaluations globally. However, its cross-cultural content validity remains underexplored. This study assesses the relevance and adequacy of EQ-5D across diverse cultural c...

Mannose-Functionalized Polymeric Micelles Target CD206-Expressing Macrophages Within Human Tuberculosis Granulomas and Improve Isoniazid Delivery

Background: Latent tuberculosis infection (LTBI) remains a global health challenge, in part due to the ability of Mycobacterium tuberculosis (Mtb) to persist within granulomatous lesions where drug exposure may be limited. Because granulomas are heterogeneous structures composed...

Orthoptera assemblages in subtropical paddy fields: role, effect of plant phenology, and cultivation area

Abstract Irrigated rice crops are considered artificial wetlands, with high productivity and biodiversity, especially in insect populations such as orthopterans. Although these predominantly herbivorous insects include several species of agricultural concern, their occurrence and...

Long-term patterns in phenotypic plasticity of chironomid head capsules in small high-elevation subarctic lakes: exploring possible mechanisms using multi-proxy paleolimnological records

Abstract We quantified temporal variation in the head capsule (HC) length of subfossil chironomids from two high-elevation subarctic lakes in northern Sweden and explored its potential drivers using chironomid assemblages, sedimentary pigments, and stable isotope analyses. Althou...

The auditory region of Acarechimys minutissimus (Rodentia, Hystricognathi) from the Early Miocene of the Argentinean Patagonia: considerations in the evolution of Pan-Octodontoidea

The auditory region of mammals is a crucial source of anatomical, biological, and evolutionary information. Despite the taxonomic diversity and ecological importance of caviomorph rodents, the auditory morphology of their fossil representatives remains poorly known. Here we descr...

Separating Common-Factor from Covariate-Specific Spillovers: An Exact SLX Score-Test Decomposition

This paper studies the score test for spatially lagged regressors (WX) in SLX modelswhen the data may also exhibit spatial dependence in the lagged dependent variable or theerror term. Building on the exact score identity of Koley (2024), Sρ = Sλ + ˆ β′ncSθ, we show that the unad...

Spatial prioritization for conserving hummingbird–plant interaction roles across Mexico

Global biodiversity goals acknowledge that conserving species alone is insufficient to maintain ecosystem functioning. Yet, spatial conservation planning rarely incorporates ecological interactions, limiting efforts to protect both species' persistence and the ecological processe...

Diagnostic Accuracy of a Commercial ELISA for Detecting Antibodies Against Strongyloides stercoralis in Dried Blood Spots: A Field Study in Puerto Iguazú, Argentina

Background: Strongyloides stercoralis is frequently underdiagnosed due to the limited sensitivity of stool-based methods. Serology improves detection, but venous blood collection and cold-chain requirements complicate field implementation. Dried blood spots (DBS) offer a practica...

Bounded-Error Goldbach Capture by Maynard Prime Clusters

This preprint establishes a quantitative bounded-error Goldbach result in which one prime summand is required to belong to a genuine bounded prime cluster. We prove that there exist a fixed admissible tuple of even shifts {h₁,…,hₖ} and a constant H₀ such that, for every A > 0, al...

Post‐fire trajectories reveal a legacy effect and decoupled structural and floristic responses in a seasonally dry subtropical mountain region

Abstract Fire is a key driver maintaining non‐forest vegetation in tropical and subtropical seasonal climates that could otherwise support forest. However, a deeper understanding of long‐term post‐fire dynamics requires tracking both structure and floristic composition in the sam...

MicroRNAs as dynamic processors: from thresholding to temporal decoding

MicroRNAs are central regulators of gene expression. Traditionally viewed as static repressors of protein output, their regulatory role is increasingly recognized as inherently dynamic. In living systems, gene regulation unfolds far from equilibrium, where signals fluctuate over...

Ecological Types Versus Taxonomic Types in Phytobenthos Composition in Four Contrasting Basins

ABSTRACT Taxonomic classification of phytobenthos is time‐consuming and requires specialized expertise, favouring growing use of trait‐based or eco‐morphological functional classifications, which may better capture the environmental heterogeneity shaping community composition. Aq...

Finite element approximation of a hemivariational inequality for steady-state heat conduction: double-limit convergence of penalization and discretization

In this paper we study the numerical approximation and convergence analysis of a steady-state heat conduction problem with mixed boundary conditions. The physical model is governed by a hemivariational inequality depending on a heat transfer parameter α > 0. We consider the finit...
