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 …

Brown, Ruey L. Loo, Kevin Taddei, Stephanie R. Rainey-Smith, Michael Weinborn, Ana Caroline R.Dos Reis, Manohar L. Garg, Ralph N. Martins, Hamid R. Sohrabi

Research outputs 2022 to 2026

Background: Preventive strategies, including adherence to specific dietary patterns, have received increasing attention as approaches to reduce cognitive decline and dementia risk. However, findings remain inconsistent, partly due to differences in dietary assessment methods, cognitive outcomes, and THE consideration of genetic susceptibility factors such as apolipoprotein E (APOE) genotype.

Methods: This study examined associations between dietary patterns and longitudinal cognitive change in 185 older adults without dementia from the Western Australia Memory Study. Participants completed a food frequency questionnaire at baseline and underwent comprehensive neuropsychological assessments at baseline and up to five follow-up visits at 18-month intervals. Composite scores were …

Ephemeral To Empowered? International Comparison Of Women’S Participation In Web Series Production, 2012–2019, Nicola Evans, Marion Mccutcheon, Emilia King, Joel Bassaget, Steinar Ellingsen

Research outputs 2022 to 2026

Women are significantly underrepresented in above-the-line roles in film and television, but anecdotal evidence suggests they are gravitating to web series. To explore this, the authors built the largest known international archive of web series released during 2012–2019 and analysed women’s participation. In the top five web series producing countries in the West, women achieved or approached parity with men in producing, directing and writing, but not cinematography. Do achievements in low-budget, transitory media count for anything? Drawing on ephemeral media scholarship, we discuss the potential of such forms to disturb entrenched patterns of gender discrimination in screen industries worldwide.

Estimation Of Persistent Inward Currents Contribution To Inspiratory Motoneuron Firing In Humans, Ricardo N.O. Mesquita, Simon C. Gandevia, Janet L. Taylor, Anna L. Hudson, Jane E. Butler

Research outputs 2022 to 2026

Persistent inward currents (PICs) are known to prolong firing of limb-muscle motoneurons. Although there is immunohistochemical evidence of PIC channels in respiratory motoneurons, it is unknown whether PICs contribute to their firing prolongation. Intramuscular electromyographic signals were recorded from human inspiratory muscles to identify motor unit (MU) activity. Diaphragm MUs were identified during quiet breathing (n = 7; one female) and MUs from the 1st, 3rd, and 5th parasternal intercostal muscles during quiet (no lung volume feedback) and voluntary (triangular-shaped lung volume feedback) breathing (n = 5 males). PIC contribution to firing prolongation was estimated via quantification of firing hysteresis …

In this study, biochar was incorporated at 3%, 6%, 9%, and 12% by weight, utilizing particles smaller than 75 µm to maximize interfacial interaction. Characterization via SEM-EDS, XRD, and TGA revealed a highly stable, carbon-rich, amorphous material with a rough, porous morphology, favourable for physical interlocking with the bitumen matrix. …

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).

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, …

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 …

Safety And Effectiveness Of Behavioural Activation For Chronic Pain: A Protocol For A Systematic Review And Meta-Analysis Of Randomised Controlled Trials, Fangyuan Zheng, Laura Hynes, Richard J. Gray, Irene Ngune, Jacqueline Sin, Martin Jones

Research outputs 2022 to 2026

Background/Objectives: Chronic pain is a prevalent and complex condition associated with substantial physical, psychological, and social burden. Behavioural activation (BA), a structured psychological intervention originally developed for depression, may be relevant to chronic pain through its focus on reducing behavioural avoidance and increasing engagement in meaningful activities. Although BA has been applied in studies involving people with chronic pain, the safety and effectiveness of BA in this population have not been comprehensively synthesised. This systematic review and meta-analysis will examine the safety and effectiveness of BA for people with chronic pain.

Introduction: The analysis of metabolic profiles using high resolution mass spectrometry (MS) data provides deep insights into biological processes. In metabolomics, MS analysis generates a large number of features that represent metabolites. However, identifying specific metabolites from these features can be challenging. One of the major bottlenecks in the metabolomics field is the identification of MS features, which is a prerequisite for any biochemical interpretation. By identifying similarities and differences within a metabolite family (mFam), evaluating MS features at the metabolite family level can help assigning functional roles to individual MS features. These data can help interpreting metabolic pathways and …

Unilateral Numbers Need Context: Reference Values For Single-Leg Cmj Performance Relative To Bilateral Cmj Capacity, Karol Kruczek, Tim Gabbett, Jason Lake, Michał Nowak

Research outputs 2022 to 2026

The single-leg countermovement jump (SL CMJ) is widely used to assess limb-specific neuromuscular function, with interpretation commonly centred on inter-limb asymmetry. However, contextualising unilateral performance relative to bilateral capacity remains less clearly defined. This retrospective cross-sectional study aimed to develop exploratory descriptive benchmarks for SL CMJ kinetic, kinematic, and temporal variables expressed as a percentage of bilateral CMJ performance in a heterogeneous athletic cohort. A total of 348 athletes completed bilateral and unilateral CMJs using dual force plate sampling at 1000 Hz. The best trials were selected using the modified reactive strength index (mRSI), and averaged unilateral variables were expressed …

What Is Left After Memory: Love, The Body, And The Unconscious In Little Fish, Paul Longley Arthur, Isabel Smith

Research outputs 2022 to 2026

Chad Hartigan’s science fiction romantic drama Little Fish was released in 2020, soon after the start of the COVID-19 pandemic. However, the disease plaguing communities in Little Fish is not affecting people’s bodies but their minds—those who have contracted Neuroinflammatory Affliction (NIA) are losing their memories. The story centres upon the experiences of one young couple as they anxiously witness the disease take hold of their community, loved ones, and eventually one another. The film explores relationships between memory and identity, and poses questions about the ways these processes interact with those of love and loss. Who are we once …

Promotion Architecture: A Deal Fairness Model Of Restricted Price Promotions, Shangwen Yi, David Hardisty, Dale Griffin, Thomas Allard

Research Collection Lee Kong Chian School Of Business

This research examines the effectiveness of two common types of restricted price promotions: threshold promotions (conditional on spending more than a threshold amount; e.g., “Get $5 off on orders of $10 or more”) and capped promotions (limited to a maximum dollar value; e.g., “Get 50% off, up to $5 per order”). Results from seven pre-registered studies, including one field study, show that threshold promotions lead to higher purchase intentions and conversion rates (but potentially lower purchase amounts) than comparable capped promotions—even though capped promotions are equivalent in maximal economic savings for the consumer—when the trigger value (the spending amount at …

Recompression Improves Release Success In Pollack (Pollachius Pollachius): A Step Towards Assessing Post Release Mortality In A Recreational Fishery, T. Stamp, R. Mawer, R. Conlon, A. E. Hall, P. Davies, R. Nesbit, D. Uren, T. Morris, S. Sullivan, S. Thomas, B. D. Stewart, H. Rudd, K. Hyder, T. Osmond, S. Reynell, E. V. Sheehan

School of Biological and Marine Sciences

The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release. Via an experimental weighted cage, this study evaluated the efficacy of releasing Pollack at depth as a barotrauma mitigation strategy. We found that depth-release significantly increased the probability of released Pollack displaying an active escape response to 83%, compared to 56% for surface-released fish; however, increased capture depth and fish size negatively affected success. Camera observations …

A Review Of Blue Carbon Credit Projects' Socio-Economic Activities, Nata Tavonvunchai, Holly J. Niner, Abigail Mcquatters-Gollop, Siân E. Rees

School of Biological and Marine Sciences

Coastal ‘blue carbon’ ecosystems (mangroves, seagrasses and saltmarshes) are critical for climate regulation and biodiversity, yet significant funding gaps persist in marine conservation. While blue carbon credits are increasingly used to bridge these gaps, concerns remain regarding their efficacy in delivering socio-economic benefits. Based on lessons from terrestrial carbon markets, failing to prioritise local community needs can lead to inequitable outcomes and externally mandated constraints, which undermine the legitimacy of nature-based solutions. This research seeks to add to the centralised understanding of the social dimension of blue carbon by delivering a comprehensive review of 77 publicly listed projects from global …

Visually Guided Foraging In Virtual Worlds: Domain-General Properties Of Search Behaviour, Sarah Salo, Alastair Smith

School of Psychology

Everyday human behaviour involves economically driven search for visually relevant targets in complex three-dimensional environments. However, psychological research has typically examined visual search and foraging mechanisms separately, with insights into search emphasising attentional efficiency, and accounts of foraging highlighting decision-making and cognitive control. In order to more closely examine the interrelation between these processes in fully motile environmental search, we devised a novel virtual reality paradigm that required participants to physically explore a large-scale 3D environment and collect multiple visually defined targets. The search environment was organised in patches, with search arrays presented across multiple tables. In single feature search, …

Gaming The Marketplace: Consumer Opportunism And Beliefs About Societal Hierarchy, Shilpa Madan, Aparna Labroo, Constantine S. Katsikeas

Research Collection Lee Kong Chian School Of Business

Consumers often behave opportunistically, taking more than what fair marketplace exchange warrants (e.g., taking excess samples, returning used items). While each individual transgression may be minor, cumulatively they can undermine firm profitability. Thus, addressing consumer opportunism is an important managerial concern. We identify a novel antecedent of consumer opportunism: consumers’ acceptance of societal hierarchy (i.e., power distance belief [PDB]), including firms’ higher position in it than consumers. Nine studies (plus two supplementary studies) employing archival, correlational, and experimental data provide converging evidence that, in marketplace interactions, this belief evokes a need to feel clever (i.e., to feel smart and knowledgeable …

Mechanical Engineering Faculty Publications

The biological growth of fungal root structure, called mycelium, can be engineered to develop innovative fibrous and biocomposite materials. Mycelium materials have potential as sustainable alternatives to petroleum-derived materials for load-bearing applications. To realize this potential, there is an increasing effort dedicated to understanding the mechanics of mycelium materials. This work presents a systematic review of our current understanding of the mechanics of mycelium materials with a specific focus on structure–property relationships. The review first explores how the mycelium’s fiber network structure varies depending on whether it is grown as a two-dimensional (2D) membrane, a cellular foam, or as a …

Of Cables And Threads: Reweaving The Urban Fabric At The Edge Of Bogotá, Federico Pérez Fernández

University Honors College Faculty Publication and Presentations

Over the past two decades, gondola lifts have become central to interventions in urbanLatin America’s auto-constructed peripheries. As cable car urbanism reshapes the city’sedge, it raises fundamental questions about the notion of the “urban fabric” as a socio-material practice, an epistemology, and a site of politics. In Bogotá, the city’s first aerialcable car line has been integrated into the sprawling district of Ciudad Bolívar, revealinga dialectical process of urban fabrication—a form of urban weaving, in the language ofboth experts and residents, that bridges technical retrofits and popular logistics. Thesestate-community interfaces operate beyond the binaries of compromise and dissent, co-optation and …

Electrical Engineering Faculty Publications and Presentations

Soil nitrate (NO3) exhibits rapid spatial and temporal variability that conventional point-sampling methods cannot effectively capture, limiting timely nutrient management and plant stress detection. This study aimed to validate a low-cost, threedimensional- printed electrochemical NO3 sensor for continuous in-soil monitoring and to evaluate whether sensor-derived NO3 dynamics reflect plant physiological responses. For this purpose, cotton (Gossypium hirsutum L.) plants were grown in pots under greenhouse conditions. The sensor was evaluated in two sequential phases: an initial calibration phase to characterize sensor response across a broad NO3 concentration range, followed by a validation phase in the cotton plant rhizosphere. In the …
