An Open-Source Evaluation Framework For Risc-V Co-Design-Based Decimal Arithmetic, Riaz Ul Haque Mian, Michiko Inoue

Research outputs 2022 to 2026

Hardware–software co-design is a balanced strategy for computationally intensive algorithms such as decimal computing. It can provide several Pareto points for the development of embedded systems in terms of hardware cost and performance. In this study, we propose an efficient and accurate evaluation framework for decimal computing. The framework was designed and developed for hardware–software co-design decimal arithmetic using the RISC-V ecosystem. New binary and decimal-oriented instructions supported by an accelerator were developed. The framework can perform cycle-accurate analysis for performance and assess hardware overhead for co-design-based decimal arithmetic. Unlike previous studies that focused primarily on implementing and evaluating individual …

Attenuation Of Redox Interference In Ruo2 Ph Sensor Using A Ta2o5/Nafion Multilayer Architecture, Wade Lonsdale, Magdalena Wajrak, Md Mahamudul Hassan, James Jin Kang

Research outputs 2022 to 2026

Despite the growing preference for solid-state pH sensors due to their advantages over glass pH electrodes, their practical application is still limited by challenges, particularly in metal-oxide based systems. The main issue is their susceptibility to redox-active species such as dissolved oxygen, ascorbic acid, sulfides, and transition-metal ions. In this work, the effects of representative redox interferents, with particular emphasis on ascorbic acid, together with dissolved oxygen and potassium permanganate, were investigated and mitigated through the application of Ta2O5/Nafion overlayers. The solid-state metal-oxide pH-sensitive electrodes were fabricated with laser micro-etching of radio-frequency (RF) sputtered RuO2 thin films deposited on ceramic …

Constitutive Behaviour, Failure Mechanisms, And Life Cycle Assessment Of Internally Cured Fiber-Reinforced High-Strength Concrete, Kastro Kiran V, Dhanya Sathyan, Sanjay Kumar Shukla

Research outputs 2022 to 2026

High-strength concrete (HSC) with low water-to-cement ratios undergoes self-desiccation, resulting in incomplete hydration, capillary porosity, and autogenous shrinkage that can compromise long-term performance. Polyethylene glycol (PEG) functions as an internal curing agent by releasing stored water as internal relative humidity decreases, thereby sustaining hydration within the cement matrix. However, the combined influence of PEG grade, dosage, and fibre type on the constitutive response, fracture behaviour, and environmental performance of M65 HSC remains insufficiently understood. This study investigated twelve concrete mixes incorporating three curing regimes viz. Conventional curing, spray curing, and PEG-based internal curing (IC) using PEG 4000 (1.5%) and PEG …

Gut Microbiome Changes In Preclinical Alzheimer’S Disease, D. M. Sithara Dissanayaka, Stephanie R. Rainey-Smith, Hamid R. Sohrabi, Thilini N. Jayasinghe, Vincent Ho, Vijay Jayasena, Kevin Taddei, Colin L. Masters, Ralph N. Martins, W. M.A.D.Binosha Fernando

Research outputs 2022 to 2026

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that develops many years before clinical symptoms appear. The biological changes involved in the earliest stages remain poorly understood, particularly during the preclinical stage. Our previous work has identified gradual gut microbial and metabolic changes during this stage, suggesting these may represent early biological shifts that precede disease progression. Recent studies suggest that the gut microbiome may contribute to early AD processes through its effects on immune regulation, metabolism, and gut–brain communication. Changes in gut microbial composition, including reduced levels of short-chain fatty acid (SCFA)-producing bacteria, such as Faecalibacterium, Roseburia, and Eubacterium, …

Research outputs 2022 to 2026

Conservation translocations require careful assessment of dietary resources to ensure population viability. Here, we used environmental DNA metabarcoding to characterise fungal assemblages across three major habitat types on Dirk Hartog Island, Western Australia, prior to the planned reintroduction of two threatened mycophagous species: the boodie (Bettongia lesueur) and woylie (Bettongia ogilbyi). We detected 243 fungal ASVs, of which 75 represented taxa that are likely to produce macroscopic fruiting bodies accessible to mycophagous mammals. Ectomycorrhizal fungi dominated all habitats, with Pezizaceae being the most abundant family—a pattern consistent with known dietary preferences of both species across multiple Australian locations. Fungal community …

Reinforcement Learning For Cathode Material Design Through Sequential Decision-Making Frameworks, Taimoor Muzaffar Gondal, Muhammad Qasim, Yasir Arafat

Research outputs 2022 to 2026

The cathode material design is a persistent challenge in the development of next-generation rechargeable batteries. The cathode performance is critically influenced by certain key parameters, i.e., composition, crystal structures, ion transport, and degradation behaviour. Moreover, techno-economic and sustainable considerations also play a pivotal role in the viable cathode material design. In recent years, the integration of static machine learning models with conventional experimental techniques has significantly enhanced the cathode material design. However, the sequential nature of cathode discovery has not been fully captured by these techniques as they do not update their decision strategy based on prior outcomes. In this …

Attraction Of Nocturnal Scarab Beetles By Unusual Floral Volatiles In A Banksia (Proteaceae) With Functionally Diverse Pollinators, S. K. Wawrzyczek, B. Bohman, S. L. Krauss, I. M. Butler, G. R. Flematti, K. Farnier, S. E. Hoebee, R. A. Davis, R. D. Phillips

Research outputs 2022 to 2026

Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by scarab beetles (Coleoptera: Scarabaeidae). However, some plant species may produce floral scents and offer floral rewards that attract scarabs alongside other pollinator functional groups. In Banksia attenuata (Proteaceae), nocturnal observations led to the discovery of extensive floral visitation by beetles, alongside birds, mammals and diurnal insects. Given the distinctive melon-like floral scent of B. attenuata, we predicted long-distance attraction of beetles by chemical cues. We undertook floral visitor surveys aided by camera traps and video recordings, and quantified insect …

Exploring Traditional Breast Cancer Risk Genes Among Aboriginal And Torres Strait Islander Women, Katie Meehan, Leanne Pilkington, Azim Khan, Nicholas Pachter, Lisa Spalding, Ayeisha Milligan Armstrong, Cameron Redfern, Andrew Redfern

Research outputs 2022 to 2026

Background: Germline pathogenic variants in BRCA1/2 increase breast and ovarian cancer risk, but their prevalence in Aboriginal and Torres Strait Islander (herein referred to as Aboriginal) families has never been studied. Consequently, their contribution to breast cancer in this population is unknown.

Methods: This retrospective cohort study included 259 Aboriginal women and 789 age- and remoteness-matched non-Aboriginal women diagnosed with breast cancer (2001–2016). We assessed family history, genetic service referral and testing rates, and pathogenic variant rates in the context of testing access.

Results: Family history data were available for more Aboriginal than non-Aboriginal cases (46% vs. 34%, p < 0.001), with no difference in reported first-degree relatives with breast (22.5% vs. 22.4%, p = 0.98) or ovarian cancer (4.2% vs. 2.2%, p = 0.29). Similar proportions were referred to genetic services for testing eligibility (5.4% vs. 7.2%, p = 0.392). Of those referred, similar proportions were offered testing (86% vs. 81%, p = 0.66). Across the full cohort, BRCA1/2 pathogenic variants were detected in 0.77% of Aboriginal versus 2.4% of non-Aboriginal women (p = 0.127); any pathogenic gene variant was detected in 0.77% versus 3.0% (p = 0.039).

Characterising Manual Dexterity, Motor Cortex Neuroplasticity, And Intracortical Inhibition Long After Burn Injury, Grant S. Rowe, Alecia Wood, Mark Fear, Dale W. Edgar, Aleksandra Miljevic, Tyler Osborne, Natalie Morellini, Merrilee Needham, Ann Maree Vallence, Fiona Wood

Research outputs 2022 to 2026

Purpose: Persistent motor dysfunction after burn injury may be due to altered motor cortex and corticospinal tract function. This study examined manual dexterity, motor cortex neuroplasticity, and intracortical inhibition in former burn patients 1–3 years after minor injury (<10% TBSA). Method: Thirty former burn patients (TBSA: 0.78 ± 1.08%) and 30 non-injured controls participated. Manual dexterity was assessed using the Purdue Pegboard. Transcranial magnetic stimulation (TMS) was used to measure motor cortex excitability (motor evoked potential [MEP] amplitude) and short- and long-interval intracortical inhibition (SICI, LICI) before and after paired-associative stimulation (PAS) to induce neuroplasticity. Results: Former burn patients performed worse than controls on the bimanual assembly subtest of the Purdue Pegboard. PAS did not induce changes in MEP amplitude but increased LICI in both burn patients and control participants. In burn patients, baseline LICI was related to bimanual performance differently than controls. Conclusions: These findings suggest poorer bimanual motor function persists after minor burns, and differences in the association between inhibition and bimanual dexterity between burn and control groups. Further research should explore whether targeting motor cortex inhibitory circuits can improve motor performance following burn injury
