Enumeration of Regular Multipartite Hypergraphs

Abstract. We determine the asymptotic number of regular multipartite hypergraphs, also known as multidimensional binary contingency tables, for all values of the parameters.

Evidence from alkaline magmatism for fluorine- and bromine-enriched cratonic mantle roots

The base of cratonic lithospheric mantle (cratonic root) is a key volatile-rich reservoir (e.g., carbon and halogens), formed through long-term metasomatism by deep-derived incipient melts, whose reactivation has been proposed to drive climatic change over the course of Earth his...

JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova

Abstract We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from ∼2 weeks before to ∼1 yr after maximum light. JWST near- and mid-infrared spectra at +276 and +363 days show ∼400 K dust emission that cools by ∼75 K between epochs, the first una...

Multi-layer network analysis of deliberation in an online discussion platform: The case of Reddit

This paper proposes a novel multi-layer network model to study deliberation in online discussion platforms. The model comprises two layers: a discussion layer, which represents as a hierarchical tree the comment-to-comment replies within a given post, and an actor layer, which re...

Dual Magnetite Formation Pathways in Abyssal Serpentinites From the Mid‐Atlantic Ridge

Abstract Serpentinization, which involves hydrothermal alteration of olivine and pyroxene in ultramafic rocks, generates magnetite and strongly modifies the magnetic properties of oceanic lithosphere. However, the microstructural pathways of magnetite formation and their bulk mag...

Reassessing the Role of the Antarctic Slope Current in Poleward Ocean Heat Transport

Abstract The Antarctic Slope Current (ASC) is often considered a barrier to the poleward transport of Circumpolar Deep Water (CDW), yet its vast extent has hindered circumpolar analysis of this relationship. Here, we use a high‐resolution global ocean‐sea ice model that resolves...

Prediction-Based Adaptive Designs for Reducing Wave Nonresponse Rates and Bias in Panel Surveys

Machine learning (ML)-based nonresponse prediction in panel surveys enables selective interventions. However, the optimal use of ML predictions in Adaptive Survey Design (ASD) remains uncertain. We propose a method that integrates field experiment results on incentives, questionn...

Mastering a simulation-based parametric method to obtain bias-corrected point estimates and sampling variance for effect sizes

Abstract Meta-analyses require an effect-size estimate and its corresponding sampling variance from primary studies. For some effect size statistics, however, estimators of sampling variance are unavailable, requiring new derivations. Traditionally, such formulas are obtained usi...

Hot Carrier Trapping in InAs Nanowires for Ultraviolet to Infrared Photodetection

Abstract Semiconducting InAs nanowires are promising building blocks for optoelectronics, but their performance is often complicated by an unusual negative photoconductivity (NPC) originating from surface charge traps. Harnessing the competition between this NPC and conventional...

The Tropological Vertex

Abstract The theory of the topological vertex was originally proposed by Aganagic, Klemm, Mariño and Vafa as a means to calculate open Gromov–Witten invariants of toric Calabi–Yau threefolds. In this paper, we place the topological vertex within the context of relative Gromov–Wit...

Cooperatively breeding white-winged choughs use recruitment calls selectively in food-associated contexts

Many social animals produce vocalizations to attract others to food, with diverse benefits including improved foraging success, reduced predation risk and access to social and reproductive rewards. In some species, the production of such calls varies based on food divisibility, b...

From pollen to pixels: Towards spatially meaningful pollen-based vegetation reconstructions across southeastern Australia

Reconstruction of past vegetation underpins understanding of long-term ecosystem and societal change, helping to contextualise present-day patterns in biodiversity, ecosystem trajectories and effective landscape management practices against historical ecosystem states. This is pa...

Canopy functional composition as an indicator of bird traits, taxonomy, and vulnerability in tropical Peruvian forests

Tropical forests harbour exceptional biodiversity, yet anthropogenic change is rapidly altering forest composition and structure in ways that shape species’ ecological strategies and persistence. While advances in remote sensing now allow detailed characterisation of canopy funct...

Phylogenetic and phylodynamic approaches to understanding the evolution of non-small cell lung cancer using single-cell sequencing

Abstract Characterizing the genealogy of tumor cells and their population dynamics is central to our understanding of the evolution of cancer. While direct monitoring of the tumor evolutionary process is impractical, we leverage advances in phylogenetics and phylodynamics to expl...

Chinese and Australian Aid in the Pacific: Which is More Effective at Developing Influence?

In 2022, China and Solomon Islands signed a security deal allowing for the Chinese navy to potentially use Honiara’s ports. In that same year, Beijing attempted to author a region-wide security pact with ten Pacific Island Countries. These moves signalled a new strategic reality...

A Novel Technique for the Distal Ureter and Bladder Cuff During Nephroureterectomy: Thulium Laser Resection

ABSTRACT The aim of this study was to evaluate the safety and feasibility of a novel technique involving the use of the two‐micron thulium fibre laser (Tm‐laser) to perform bladder cuff excision (BCE) during radical nephroureterectomy (RNU). We conducted a retrospective review of...

The Lived Experience of Children and Adults with Overweight or Obesity Engaging in Weight Management Treatments: An Umbrella Scoping Review with Narrative Synthesis

ABSTRACT Introduction Understanding the lived experience of people with overweight or obesity is essential to ensure that interventions are free from weight stigma, avoid adverse consequences including eating disorder pathology, increase engagement, and promote culturally sensiti...

A refined Saccharomyces cerevisiae reference transcriptome from Direct RNA Sequencing, with a reusable pipeline for UTR annotation updates

Untranslated regions (UTRs) flanking the coding sequence govern mRNA translation, localisation, and decay, making accurate UTR boundaries essential for quantitative RNA sequencing and the study of post-transcriptional control. Reference transcriptomes built from short-read sequen...

Discovery of a New Triterpenoid and Chemical Profiling of Mudjala (Barringtonia acutangula), an Australian Indigenous Medicinal Plant

Mudjala bark, prepared from Barringtonia acutangula, is an Australian Aboriginal medicine traditionally used for pain relief, and previous studies have associated its activity with triterpenoid-rich fractions. However, the low-molecular-weight triterpenoids, which were major chro...

Dosimetry, Toxicity and Stability Associated With a Hyaluronic Acid‐Based Prostate‐Rectal Spacing Device During Prostate Radiation Therapy: A Retrospective Comparative Analysis

ABSTRACT Introduction Hypofractionated radiation therapy (HFRT) for localised prostate cancer may increase gastrointestinal (GI) toxicity. This study evaluated spacer geometry, dosimetric and clinical outcomes associated with the use of a stabilised hyaluronic acid (sHA)‐based re...
