Potential predation impacts of invasive non-native rodents (black rats) on plant species from a Pacific Island (Lord Howe Island, Australia)

Context Invasive non-native rodents pose a significant threat to a range of plants on oceanic islands, particularly where there are high levels of endemism. Aims On Lord Howe Island in the western Pacific Ocean, prior to rodent eradication measures, we used selective caging and c...

Stochastic Reproduction Number and Ergodicity of a Saturated-Incidence SIHR Rumor Model with Optimal Control

This paper develops a stochastic susceptible–infected–hesitating–removed (SIHR) rumor model with Hill-type saturated incidence and compartment-specific Brownian perturbations. The model focuses on when environmental noise changes a rumor’s deterministic fate and how long-run beha...

Clustering without clusters: the meta-criterion and centroid reliability mistake continuous dynamics for discrete states

Microstate analysis starts with clustering and the meta-criterion is a heuristic to find an optimum cluster number. We address the following questions: (i) what number is found for non-cluster-forming dynamical systems, (ii) do centroids fall in random attractor regions, (iii) do...

Centering equity, diversity and inclusion in environmental evidence synthesis: from awareness to action

Abstract Knowledge generated through evidence synthesis is an approach that decision-makers can take to inform policy and management decisions. Evidence syntheses, such as systematic reviews, provide quantitative and qualitative summaries of this evidence, using structured method...

Contraceptive and condom use among women from key populations in Myanmar

Abstract Background Contraceptive and condom use remain low among women in marginalized communities, including those who sell sex, use or inject drugs, or are sexual partners of people who use or inject drugs (key populations). This study examines how selling sex and drug use rel...

In Situ TEM Study of the Size-Dependent Solubility of Metals in Liquid Metal Nanodroplets

Abstract Characterizing metal solubilities in post-transition-based liquid metals remains challenging due to their inherent opacity to conventional light-based analytical techniques. In this work, we present an in situ heating methodology within a transmission electron microscope...

Spatial heterogeneity in exposure to Brucella suis and pathogenic leptospires in feral pigs across New South Wales

Feral pigs (Sus scrofa) are important reservoirs for zoonotic and livestock pathogens in Australia, but robust information on the spatial distribution of pathogens in pig populations remains limited. We analysed serological data from a systematic, state-wide surveillance program...

Sodium butyrate rescues long-term neurodevelopmental deficits following perinatal methadone exposure

Abstract Background Prenatal opioid exposure (POE) induces long-term neurodevelopmental, behavioral and cognitive deficits for which no targeted treatments are available. The mechanisms underlying POE deficits are poorly understood, but have been linked to a range of central, per...

Combining Implementation and Data Sciences to Accelerate Evidence Integration into Healthcare – ImpleMATE

Background The translation of research evidence into routine healthcare practice is often slow and inconsistent, even timely implementation can significantly improve patient outcomes. While implementation science offers strategies to close this gap, current approaches are frequen...

Moving beyond sexual and reproductive health knowledge: an evaluation of a co-designed digital engagement tool to promote sexual and reproductive health among international students in New South Wales, Australia

Background This study evaluates the perceived impact and needed enhancement of a co-designed digital sexual and reproductive health (SRH) tool (‘the Hub’) developed to address SRH literacy gaps among international students (IS) in New South Wales, Australia. Despite Australia’s l...

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils ( Sarcophilus harrisii ) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Piniku...

The development and initial validation of the Perinatal Intrusions Interpretation Index: A novel scale that measures negative appraisals of infant‐related intrusive thoughts

OBJECTIVES: Unwanted and often distressing intrusive thoughts of infant-related harm are common during the perinatal period and are associated with poorer maternal mental health. The mechanisms linking perinatal intrusive thoughts to mental health remain poorly understood. One pr...

Hidden translation costs in cell and gene therapy manufacturing

Ex vivo cell and gene therapies have demonstrated remarkable clinical efficacy, yet their widespread adoption remains constrained by the complexity and cost of translation and manufacture. Current development commonly progresses through different equipment architectures: standard...

ANZTCT cytomegalovirus practice survey for allogeneic haemopoietic stem cell transplant and cellular therapy recipients in Australia and New Zealand

BACKGROUND: Despite pre-emptive treatment (PeT), cytomegalovirus (CMV) disease and reactivation remain a clinical concern. In Australia and New Zealand (ANZ), variability exists in the management of CMV for haematopoietic stem cell transplantation (HSCT) recipients. AIMS AND METH...

Oxygen vs Air at Birth for Moderate- to Late-Preterm Infants

Importance The optimal initial fraction of inspired oxygen (F io 2 ) for delivery room resuscitation of neonates born at 32 to 35 weeks’ gestation is unknown. Objective To compare outcomes for neonates born at 32 to 35 weeks’ gestation when initiating resuscitation with F io 2 0....

Quenched Inclusions in Uralian-Alaskan Placer Pt-Fe Nuggets, Ecuador: Rare Cu-PGM Telluride-Sulfide Parageneses

PGM (platinum-group mineral) melt inclusions set in two Pt-Fe alloy nuggets are from the Camumbi River placer, Ecuador. Inclusion bulk compositions are strongly fractionated, mutually exsolved melts Pt–Rh–Pd–Cu > Fe–Ni sulfide-rich and Pt–Cu–Rh ≈ Pd > Fe–Ni telluride-rich respect...

Pointwise Replicable Agnostic Learning: The Additive Term Is Unnecessary and the Fixed-Confidence Order Is Exact

Hopkins, Impagliazzo, and Ye (arXiv:2510.20200) introduced $\rho$-pointwise replicable learning and proved that every class of VC dimension $d$ admits a pointwise replicable agnostic $(\alpha,\beta)$-learner with $\widetilde O(d/(\rho^2\alpha^2)+1/(\rho^2\alpha^4))$ samples, aski...

A cost-effectiveness analysis of selective decontamination of the digestive tract in mechanically ventilated patients in the intensive care unit

Objective To evaluate the 24-months cost-effectiveness of selective decontamination of the digestive tract (SDD) versus standard care in mechanically ventilated Intensive Care Unit (ICU) patients. Design Within‑trial cost‑effectiveness analysis using linked administrative healthc...

Machine learning-based temperature mapping in Sydney: Accuracy, transferability, and scalability

Urban heat is a growing concern for public health, energy demand, and urban liveability. High-resolution air temperature (T a ) data are needed for developing effective, localised adaptation strategies, but obtaining such data at the city scale remains a challenge as weather stat...

Quadratic Sample Complexity for Strictly Replicable Realizable Learning with Unknown Marginals

Under the quantifier "there exists A for all D", where the realizable distribution and its marginal are unknown, we determine the finite-class sample-complexity exponent for strict replicability: two independent samples and one shared seed must produce identical functions. For ep...
