Research outputs 2022 to 2026

Purpose: This paper aims to explore how the gendered structures and expectations of neoliberal academic institutions inform and shape work–family trade-off considerations for women academics in Australia. It also sheds light on how these negotiations, and at times, the ensuing career or family gap, are experienced. In doing so, the paper deepens our understanding of the systematic barriers which do not only lead to gender inequalities in academia but also have broader individual and social implications. Design/methodology/approach: This exploratory study is based on qualitative semi-structured interviews, which were thematically analysed to identify how female academics navigate the expectations associated with …

An Exploration Of Audio-Score Techniques And Practices, Lindsay Vickery

Research outputs 2022 to 2026

This paper discusses the emergence of the Audio Score as a distinct compositional practice in which auditory communication, rather than visual notation, is the primary medium through which compositional information is conveyed to performers. Drawing on recent theoretical writing by Bhagwati, Sdraulig and Lortie, Schimana, and d’Heudières, the study situates Audio Scores within the evolution of technological, aesthetic, and ideological developments. The discussion proposes a framework distinguishing three core roles of auditory material in Audio Scores— orientation, emulation, and instruction—and seeks to clarify the boundaries between Audio Scores and adjacent practices. The analysis foregrounds performer experience as a critical site …

Protecting Galápagos’ Marine Ecosystems: Biosecurity And Network Design Against Invasive Species From Tourist Vessels, Marnie L. Campbell, T.U. Le, Chad Hewitt

Research outputs 2022 to 2026

The modern world is characterized by high connectivity, enhancing economic productivity, and global communication, but outpacing our ability to manage its consequences. This connectivity increases the risk of pathogen, pest, and invasive species transmission. In the Galápagos islands, Ecuador, tourist vessel networks operate with limited restrictions and connect high conservation value locations, boosting tourism and the economy. These vessels frequently travel between multiple islands, leading to moderate connectivity and high vessel promiscuity. To prevent the spread of invasive species via these vessels, we propose a biosecurity system that combines social network tools with risk management frameworks that balances environmental protection …

Okiro, Natalie Strobel, Bibian N. Robert, Emily Odipo, Peter M. Macharia, Anthony Danso-Appiah, David C. Goodman, Queen Dube, Gagan Gupta, Hema Magge, Karen Edmond

Research outputs 2022 to 2026

Background: Evidence-based global guidance on safe travel time for small or sick newborns who require transfer to health facilities after birth is lacking. A two-hour threshold is frequently cited in low- and middle-income countries (LMICs), while 30 minutes is commonly used in high-income countries (HICs). Although these thresholds are widely referenced, their empirical basis and consistency across levels of newborn care and journey types have not been systematically examined. This study synthesises the evidence linking travel time and perinatal outcomes. Methods: We conducted a systematic review with narrative synthesis and meta-analysis to assess the impact of travel time or distance …

Doecke, Pratishtha Chatterjee, Steve Pedrini, Hamid R. Sohrabi, Nicholas J. Ashton, Henrik Zetterberg, Manohar L. Garg, Kaj Blennow, Ralph N. Martins

Research outputs 2022 to 2026

Alterations in plasma sphingomyelin (SM) levels have been reported in Alzheimer's disease (AD), pointing to disturbances in lipid metabolism that may contribute to disease pathogenesis. Neuronal damage in early AD triggers tau release into central and peripheral systems. Despite influence from peripheral contributions, alterations in plasma total-tau (T-tau) remain valuable in indicating AD-related neurodegeneration. Investigating relationships between SM metabolism and tau release during preclinical AD may uncover important biochemical processes and support advancing early non-invasive detection and treatment approaches. This cross-sectional study investigated cognitively unimpaired (CU) older adults from the KARVIAH cohort, grouped by cortical amyloid-β (Aβ) status through positron …

A Generative Ai Method For Minority Class Handling In Anomaly Detection With Drift And Explainability Analysis, Kelvin J. Mwiga, Mussa A. Dida, Ahmad Mohsin, Iqbal H. Sarker

Research outputs 2022 to 2026

Artificial Intelligence, particularly machine learning (ML) algorithms, plays a crucial role in detecting cyberattacks, including anomalies and intrusions. However, machine learning models trained on imbalanced cybersecurity datasets often struggle to accurately detect minority data instances and potential threats, thereby weakening overall system security. Despite extensive research, a persistent challenge is the inadequate explanation for model predictions concerning minority data classes. This study aims to address these limitations by developing a generative AI-based approach to manage minority classes in anomaly detection, incorporating concept drift handling and explainability analysis. We introduce an over-sampling technique, CGGReaT, designed to enhance the presence of minority …

Dynamic Load Assessment Of Pem Fuel Cell Systems Under Pid-Based Control Strategies For Sustainable Operation, Tarek Abedin, Paw, Normy Norfiza Abdul Razak, Chen Chai Phing, Yaw Chong Tak, Monowar Mahmud, Manzoore Elahi M. Soudagar, T. M. Yunus Khan, Mohammad Tariqul Islam, Mohammad Nur-E-Alam

Research outputs 2022 to 2026

Proton exchange membrane fuel cell (PEMFC) systems’ reliable operation under variable load conditions is a significant challenge because of voltage fluctuations, transient variations, and the high computational requirements of sophisticated control techniques like intelligent and model predictive controllers. Even while these state-of-the-art methods provide great precision, complexity and cost often limit their real-time applicability, underscoring the need for a simpler but efficient control solution. To achieve effective voltage regulation in PEMFC systems, this study suggests a DC–DC buck converter in conjunction with a comparator-based proportional–integral–derivative (PID) control technique. In order to provide stable operation under both constant and changing load …

Research outputs 2022 to 2026

Coastal marshes, recognized as effective organic carbon (OC) sinks, have gained attention for their potential contribution to climate mitigation through protection and restoration. However, the climate mitigation potential of Nordic coastal marshes remains understudied, likely due to their heterogeneous and often non-tidal nature. To fill this gap, we examined soil OC storage and accumulation rates, and the effects of grazing, a common management practice, across eight Nordic coastal marsh areas spanning broad climate and environmental gradients. We also assessed soil methane emissions in selected areas. The Nordic marshes studied store a median of 7 kg OC m⁻² (interquartile range, …

Between-Session Reliability And Sensitivity Of Force Production Characteristics Across Various Force-Time Points During The Isometric Single-Leg Long-Lever Bridge, Adam E. Sundh, Nicholas J. Ripley, A. J. Lamb, Conor J. Cantwell, Paul Comfort

Research outputs 2022 to 2026

The purpose of this study was to assess the between-session reliability of peak force and early force-time variables in a unilateral isometric hamstring assessment (isometric long-lever bridge). The sample consisted of 30 collegiate male athletes (age: 19.4±1.3 years; height: 1.79±0.1 m; body mass: 80.4±10.3 kg) with no history of recent hamstring injury (<6 months) who volunteered to participate in the study. All participants performed 3 unilateral maximal voluntary isometric contractions (MVIC) with their heels on force plates and shoulders elevated 15.24 cm, while their hips were secured with a loaded barbell. Data was analyzed to assess the reliability of force values at 50, 100, 150, 200, 250 ms, and peak force (N) across three repeated sessions. Moderate-good relative and absolute reliabilities were observed across all early force-time variables with lower bound ICC values≥0.51 (0.51–0.71) and point estimate CV%≤12.65% (7.63–12.65), with moderate relative (ICC≥0.74; range 0.74–0.92) and absolute (CV%≤6.50%; range 6.48–6.50) reliability for peak force. Trivial to small effect sizes (g≤0.4) were observed between sessions. These findings suggest that the isometric single-leg long-lever bridge (SL-LLB) can be used to reliably monitor peak and rapid force generating capacities to track performance changes over time due to training adaptations as well as acute or chronic fatigue.

Research outputs 2022 to 2026

NRAS mutations occur in 10%–30% of cutaneous melanomas and are associated with high tumor mutational burden. Mutant NRAS signaling drives aberrant cell growth and proliferation, in part, through activation of the RAF–MEK-ERK1/2 kinase pathway; however, targeted therapies to this pathway have limited effectiveness in patients with NRAS mutant melanoma. The role of other targetable signaling pathways in NRAS mutant melanoma is poorly characterized. Here, we demonstrated that one isoform of diacylglycerol kinase, diacylglycerol kinase eta (DGKη), a lipid signaling regulator, was highly expressed in NRAS mutant melanoma patient samples. Knockdown of DGKH in NRAS mutant melanoma cell lines resulted in …

Comparative Fatigue Analysis Of Cf-Pla Metamaterial Bone Plates For Orthopaedic Fixation, Ani Daniel, Hamed Bakhtiari, Barun K. Das, Muhammad Aamir, Majid Tolouei-Rad

Research outputs 2022 to 2026

Bone plates are widely used in orthopaedic surgery to stabilise fractured bones and support healing following traumatic injuries or osteotomies. However, conventional metallic bone plates suffer from stress shielding and stiffness mismatch with bone, which can hinder optimal healing. Additive manufacturing enables the incorporation of novel metamaterial architectures into polymer-based implants to enhance mechanical properties. The fatigue behaviour of these implants during the healing period is critical to ensuring their structural integrity and long-term performance. In this study, the compressive fatigue performance of fused deposition modelling (FDM)-printed carbon fibre-reinforced polylactic acid (CF-PLA) bone plates were investigated. Four metamaterial structures—tetrachiral, re-entrant, …

Research outputs 2022 to 2026

Hydrogen generation through serpentinization reactions in peridotite formations under high temperature conditions represents a promising avenue for subsurface hydrogen production. However, the thermal energy in the formation environment have not been sufficiently considered. To integrate hydrogen production with thermal energy development, this study develops a thermo-hydro-chemical coupled numerical model, which is used to investigate hydrogen-thermal co-development in hydraulically fractured peridotite. Given that the hydrogen-thermal co-development process involves fluid flow, heat transfer and serpentinization reactions, the governing equations are formulated based on Darcy flow and energy conservation equations, with serpentinization kinetics incorporated through the reactive source terms. To evaluate hydrogen production …

Recovery Timeframe Is A Critical Component In Preserving Carbon Stocks In Disturbed Tropical Seagrass Meadows, Taylor Renee Condron, Timothy M. Smith, Paul H. York, Nicholas J. Murray, Pere Masque, Michael A. Rasheed

Research outputs 2022 to 2026

Seagrass meadows, though covering a small percentage of the ocean floor, play a critical role in marine carbon sequestration. However, the mechanisms behind this role remain uncertain due to challenges in mapping seagrass extent and flux, accounting for spatial variation in carbon storage, and incorporating site-specific histories. This study investigates the effects of short-term (≤10 years) seagrass loss on sediment carbon stocks within a large seagrass meadow in the Great Barrier Reef region. Using remote sensing data to construct a seagrass recovery timeline, combined with field sampling and assessments of ecological factors, we found higher sediment organic carbon in areas …
