Wilson Sibbett

Abstract Wilson Sibbett was internationally recognized for his groundbreaking work in ultrafast laser science, in the generation of novel picosecond and femtosecond pulse sources, their application and for the development of pulse measurement techniques allowing direct, real-time...

AutoEmulate: A PyTorch tool for end-to-end emulation workflows

Computational simulations lie at the heart of modern science and engineering, but they are often slow and computationally costly. A common solution is to use emulators: fast, cheap models trained to approximate the simulator. However, constructing these requires substantial exper...

Plasma proteomes of obesity and allometric body shapes in the EPIC cohort

Abstract General obesity (high body mass index, BMI) affects circulating proteins. Obesity-related outcomes, however, differ by body shape but waist and hip circumferences cannot distinguish abdominal from general obesity. We therefore used the allometric body shape index (ABSI),...

Thermoregulatory and plasma neurobiomarker responses to heat tolerance assessment in exertional heat illness and matched controls

Abstract Exercise in the heat and elevated tissue temperature are associated with neuronal stress and changes in blood–brain barrier (BBB) function. More severe thermal insult may manifest as exertional heat illness (EHI) and complication by central nervous system (CNS) dysfuncti...

Integration of lipidomic and polygenic risk scores within contemporary clinical cardiovascular risk assessment pathways: a multi-cohort development and validation study

Background Guideline-recommended clinical risk scores such as AusCVDRisk underestimate cardiovascular disease (CVD) risk in a substantial proportion of individuals who later experience events, with up to 65% initially classified as low or intermediate risk. This limitation is mos...

A Modular Variable Stiffness Co‐Bot System Achieving Tasks Flexibility and Contact Compliance

ABSTRACT Enhancing contact compliance and task flexibility is essential for expanding the real‐world use of robotic systems. This paper presents a modular collaborative robot system that combines antagonistic actuation with hybrid soft–rigid variable‐stiffness components, includi...

Radiocarbon in atmospheric CH 4 and CO 2 at Jungfraujoch in 2019–2024: influence of regional nuclear emissions and current global atmospheric 14 CH 4 signal

Abstract. Radiocarbon (14C) is a valuable tracer to determine the relative fossil fractions of emitted carbonaceous greenhouse gases, such as CO2 and CH4. While atmospheric ∆14CO2 measurements have been conducted at multiple sites for several decades, ∆14CH4 measurements remain m...

Forecasting COVID-19 cases in US states using reconstructed incidence data

Abstract Branching process models are commonly used in infectious disease forecasting and often rely on daily incidence data, but their utility can be restricted if incidence is not reported daily or if reporting becomes less frequent during prolonged outbreaks. In this study, an...

Locating Moonquakes With Single‐Station Seismology

Abstract Renewed international interest in lunar seismometer deployments requires robust single‐station location approach for the highly scattering Moon's crust. We present an event‐location strategy using major lunar event types recorded by the Apollo seismic network. Frequency‐...

Characteristic-Vector Congruences for Weak Primary Pseudoperfect and Giuga numbers

Let $\mu\in\{-1,1\}$, and suppose that an integer $n>1$ satisfies \[a:=\frac{\mu}{n}+\sum_{p\mid n}\frac1p\in\mathbb Z.\] Writing $r=\omega(n)$ for the number of distinct prime divisors of $n$, we associate to $(n,a,\mu)$ an integral unimodular star lattice of determinant $\mu$ a...

“Thin Adoption” and Hidden Costs of OpenBIM Interoperability: Mixed-Methods Study in China’s Construction Industry

Abstract Building information modeling (BIM) is a collaborative process for creating and managing digital representations of physical and functional characteristics of facilities, central to the digital transformation of the architecture, engineering, and construction (AEC) indus...

Evaluating the Stability of Oxide‐Derived Cu─Sn Catalysts for CO 2 Reduction in Zero‐Gap Electrolyzers

ABSTRACT Bimetallic electrocatalysts hold substantial potential for scaling up CO 2 electroreduction, yet their practical deployment is hindered by a persistent gap between conventional three‐electrode testing and industrially relevant electrolyzer conditions. In this study, we e...

Eccentric compressive behaviour of horizontal circumferential joints in concrete wind turbine towers considering joint opening

Horizontal circumferential joints are critical load-transfer regions in the concrete segments of steel–concrete hybrid wind turbine towers. However, existing studies and design methods generally treat the annular concrete section as a continuous member and do not explicitly consi...

Comparing the readability of AI-generated and society-authored patient information leaflets in orthopaedics

Abstract Introduction Effective patient education is critical in orthopaedic care, influencing satisfaction, adherence, and outcomes. Artificial intelligence (AI), particularly large language models (LLMs), could offer the potential to improve patient information leaflets (PILs),...

Momentum-based access and speed control for improved safety in heterogeneous road networks

The increasing variety of means of transportation, including light vehicles like e-scooters and e-bikes, together with the increasing weight of conventional vehicles due to electrification and consumer preferences for SUVs, are raising serious concerns regarding the safety of roa...

Latent paths in mode choice models: incorporating street-level environment features for active travel policy

There is growing empirical evidence that walking and cycling are influenced by street-level environment features such as greenness and traffic stress. To assess active travel policy, these features are increasingly incorporated into mode choice models through predictors that aggr...

Phase-matching-free sensing with undetected light using a nonlinear thin-film metasurface

Abstract In this article, we report classical sensing with undetected light at a wavelength of 1500 nm, detected on a silicon camera at 580 nm, using four-wave mixing from a plasmonic metasurface. The bidirectional nonlinear scattering due to inherent reflections from such thin n...

Prediagnostic circulating 25-hydroxyvitamin D and prostate cancer-specific survival: a collaborative pooled analysis of 13 prospective studies

Abstract Background Previous research suggests higher risk of prostate cancer diagnosis in men with high vitamin D serology, but there are limited data related to prostate cancer survival. In this study, we examine the associations between prediagnostic circulating levels of 25-h...

Dissecting Anomalies in Conditional Asset Pricing

This paper introduces a novel methodology for analyzing anomalies in conditional asset pricing models with time-varying risk exposures and premia. Our approach extends the conventional two-pass methodology to include both ordinary and weighted least-squares estimation in a condit...

To stall-cell or not to stall-cell: Variational data assimilation of 3D mean flow past a stalled airfoil

The full-field reconstruction of three-dimensional (3D) turbulent flows from sparse experimental measurements remains a significant challenge, particularly for flows exhibiting complex 3D flow separation. In this work, we address this challenge for the case of stall cells - spanw...
