Ethyl-iophenoxic acid as a serum biomarker for marsupial species in oral bait trials

Abstract Ethyl-iophenoxic acid (Et-IPA) is widely recognized as a useful biomarker to confirm oral bait consumption in eutherian species. In historical studies on marsupials, Et-IPA was rapidly eliminated from brushtail possums ( Trichosurus vulpecula ) and swamp wallabies ( Wall...

The largest 5th pivot may be the root of a 61st degree polynomial

Abstract This paper introduces a number of new techniques in the study of the famous question from numerical linear algebra: what is the largest possible growth factor when performing Gaussian elimination with complete pivoting? This question is highly complex, due to a complicat...

Search for axions and dark photons using single molecule magnets

Molecular magnets, although analogous to familiar macroscopic magnets, offer a platform for next generation magnetic storage technologies with far higher data densities and prospective applications in quantum information science. When exposed to an external magnetic field, single...

Small clusters of $$^4$$He atoms in finite-cutoff effective field theory

Small clusters of \(^4\) He atoms are benchmark systems for universal few-body physics near the unitary limit. We study these systems using a finite-cutoff effective field theory calibrated to low-energy observables from the realistic LM2M2 potential. The chosen two-body cutoff r...

A study on the solidification behaviour of Al–Cr–La alloys in the aluminium-rich region

Abstract This study examines the solidification behaviour of Al–Cr–La alloys, reflecting the increasing use of rare-earth elements to enhance the properties of aluminium alloys. The research aims to determine how the new ternary phase Al 20 Cr 2 La, formed by the addition of La,...

A cluster-randomized controlled trial of a family-based psychosocial intervention to prevent childhood obesity from preschool ages: the PRESAFALIN study protocol

Abstract Background: Childhood obesity is a major global concern, and Spain's high obesity rates highlight the urgent need for effective and innovative interventions in early age. The PRESAFALIN study aims to promote parental competence, self-efficacy, and resilience to improve c...

Enhancing detection of polygenic adaptation: a comparative study of machine learning and statistical approaches using simulated evolve-and-resequence data

Abstract Background Detecting signals of polygenic adaptation remains a significant challenge in population genomics, as traditional methods often struggle to identify the associated subtle, multi-locus allele-frequency shifts. Here, we introduced and tested several novel approac...

Relative burden of neglected tropical diseases among school-age children in rural and urban slum settings in Eastern Ethiopia

Abstract Introduction: Despite the determination to succeed in eliminating neglected tropical diseases, these have been increasing within certain endemicities, particularly in depriving region. Objective: This study aimed to assess the relative burden of neglected tropical diseas...

Core-Shell Perovskite Fibers for Dual Emission and Random Lasing in an Aqueous and Acidic (pH = 3) Medium.

Random lasing (RL) from perovskites is highly attractive for achieving speckle-free imaging owing to its low spatial coherence. However, the intrinsic instability of perovskites limits their practical applications. Here, to overcome this, we encapsulate different metal-halide per...

Leveraging DataCite DOIs for Software Citation and Reuse

TTC7A deficiency: A retrospective international study on treatment and outcomes from the Inborn Errors Working Party of EBMT

Tetratricopeptide repeat domain 7A (TTC7A) deficiency is a primary immunodeficiency due to mutations in the TTC7A gene. It causes intestinal disease and a poorly characterized immunodeficiency, with poor long-term survival. We describe the clinical and immunological characteristi...

An Integer Proton Construction and a Numerical Coincidence with Neutron Beta Decay

Starting from a previously proposed mass–charge regularity for first-generation fermions , we construct an additive arithmetic model for the proton and the neutron based solely on mass and charge constraints. The proton solution naturally selects the integer pair (82, 161), while...

Pregeometric Relational Dynamics and Universal Causal Structure: Spectral Constraints, Response Limits, Universal Null Calibration and Functional Consistency of Light

This work develops a unified framework for pregeometric relational dynamics, asking how locality, geometry and a universal causal structure can arise as effective properties of an underlying system that is not assumed to possess a manifold, metric or causal order from the outset....

Periodicity of Nuclear Structure and Emergent Electronic Periodicity

This working note presents a nuclear filling grammar based on the pairing of particles into structured units (clusters), and shows that it regenerates, with a restricted alphabet and no adjusted parameter, four independent registers over periods 1 to 4 of the periodic table: the...

The T3 Framework: Black Holes as Global Vortex Bound States T3 框架:黑洞作为全局涡旋束缚态

Abstract This paper proposes a vortex bound state picture of black holes based on T3 ternary algebra (e²=1, i²=-1, ei=ie=0). Core updates in v1.4: Causal Structure Self-Consistency: V_c = c√2 is the Euclidean norm in velocity space; the axial projection is always ≤ c. The “superl...

What an adversarial audit of a preregistered program finds: two rounds of corrections across ten preprints, and the gaps that produced them

A research program that preregisters its protocols publicly, runs each once, and re-verifies its quoted numbers mechanically can still be wrong in ways none of those safeguards detect. We report two audit rounds of such a program — ten preprints on perturbational complexity and r...

Field-level perturbational complexity is not a proxy for neuronal reproducible dimensionality; its within-brain state changes co-vary in direction

Perturbational complexity is measured from field potentials, yet the quantity of interest lives in neuronal populations. Whether the field-level measurement reflects the reproducible richness of the underlying spiking activity — or a field-specific shadow — has never been tested,...
