School of Engineering, Computing and Mathematics

We present HiRep v2, an open-source software suite for high-performance lattice field theory simulations with dynamical Wilson fermions in higher representations of SU(Ng) gauge groups. This new version fully supports graphics processing unit (GPU) acceleration, optimizing both gauge configuration generation and measurements for NVIDIA and AMD GPUs. HiRep v2 integrates improved gauge and fermionic lattice actions, advanced inverters, and Monte Carlo algorithms, including the (Rational) Hybrid Monte Carlo ((R)HMC) with Hasenbusch acceleration. It exhibits excellent scalability across multiple GPUs and nodes with minimal efficiency loss, making it a robust tool for large-scale simulations in physics beyond the Standard Model.

Flicking Fibres: Microfibres Act As Sensory Disruptors In A Marine Crustacean, Ari Drummond, Alexander D.M. Wilson, Lucy M. Turner, Mark Briffa

School of Biological and Marine Sciences

Anthropogenic inputs to the environment—including microplastics and microfibres—are global stressors known to impair multiple facets of organismal biology. However, the effects of these pollutants on sensory structures remain critically understudied. Sensory systems mediate organism-environment interactions, and pollution-derived impairment at these interfaces may cascade through bioprocessing, from information acquisition to behaviour and ultimately fitness. Microfibres, in particular, pose an additional threat, potentially physically obstructing sensory organs and chemically interfering with sensory processes. Using an invertebrate model of sensory biology, Pagurus bernhardus, we tested whether dryer lint—a complex, heterogeneous mix of treated microplastic and cellulose fibres, and other anthropogenic contaminants—acts as a …

Changing Pseudo-Nitzschia And Dinophysis Distributions In The North Sea And Western Approaches (Ne Atlantic) And Their Potential Use In Biodiversity Assessments, Matthew M. Holland, Eileen Bresnan, Martin Edwards, Matthew Faith, Clare Ostle, Rowena Stern, Paul Tett, Claire Widdicombe, Callum Whyte, Abigail Mcquatters-Gollop

School of Biological and Marine Sciences

Pseudo-nitzschia and Dinophysis are two commonly occurring phytoplankton genera along Europe’s Atlantic coast. Species within these genera can produce toxins that accumulate in shellfish and pose health risks if consumed. Sustained monitoring of shellfish growing waters has generated decades-long time-series for these two genera, which have been considered for use in statutory biodiversity assessments as proxies for diatoms and dinoflagellates. There is also evidence that distributions are shifting; It is important to document these changes to anticipate risks for shellfisheries, and higher trophic levels. We assessed whether Pseudo‑nitzschia and Dinophysis data could support statutory biodiversity assessments and quantified distributional change …

Global Study On Newborn Hospitalization And Parental Experiences (Hope): Rationale And Design Of A Multinational Cross-Sectional Mixed-Methods Online Survey, Hope Study Working Group, Julia Hoffmann, Ruth Kemper, Helmut Hummler, Ayse Düzenli, Luc J I Zimmermann, Silke Mader, Christina Tischer, Jos Latour

School of Nursing and Midwifery

INTRODUCTION: Newborns who are born too soon, too small or sick are a vulnerable group who require special/high-dependency/intensive care after birth. Infant and Family-Centred Developmental Care (IFCDC) is an integrated healthcare approach that prioritises and values parental/familial involvement and participation by fostering competencies in essential newborn care skills and thus parental empowerment. There is a paucity of data globally on the IFCDC practice and the challenges faced by parents/caregivers during hospitalisation and post-discharge and the potential country-specific support.

OBJECTIVE: The primary objective of the HOPE study (Global Study on Newborn HOspitalization and Parental Experiences) is to assess parents'/caregivers' experiences, needs …

Nature-Based Solutions, green-finance instruments and policies are now routinely constructed around carbon sequestration/storage (CSS) and nutrient bioremediation (NB). This integration builds on how Market-Based Instruments (e.g. payments-for-ecosystem-services) are regularly used in policies focused on terrestrial ecosystems. In marine and coastal systems poor understanding of CSS/NB biophysical processes and impacts of ecosystem quality/stressors, combined with methods and governance framework knowledge gaps, generate substantial uncertainty in outcomes. Reductions in output confidence preclude integration into Nature-Based Solutions, stifling market-based investment centred on conserving and restoring temperate coastal ecosystems. To navigate this complex, rapidly evolving area, researchers from six continents engaged in a Priority …

‘Mobile Consumers’: Interpreting The Consumption Perceptions, Practices And Experiences Of Mobile Brazilian International Students In London, Mark Holton, Leonardo Santana Dos Santos Rodrigues

School of Geography, Earth and Environmental Sciences

This paper advances existing work on the mobilities and geographies of students by examining the complexities and contestations affecting international students' consumption perceptions and experiences. This is important in positing new ways of understanding how educational mobilities, in both their meta and micro forms, can influence, and be influenced by, consumption practices and ideologies. Drawing on a set of semi-structured interviews with Brazilian international students living and studying in London, UK this paper draws together mobilities and consumption theories as a lens for interpreting consumption knowledge and practice as an evolving and iterative set of performances that align closely with …

The Future Is Now: The Digital Dentistry Symposium, Casper Jonker

Peninsula Dental School

Introduction: From the perspective of our current undergraduates the period that I grew up in must appear something akin to a technological Stone Age. Concepts such as browsing web pages were unheard of, everything was done on paper, and communication could take weeks or even months to complete. Something as simple as making a phone call could cause endless frustrations: not being able to reach someone or just leave a voice message, running out of credit mid-conversation or ridiculously high phone bills was the norm in most households. Most of us will remember our time attending primary and secondary school, …

University Challenges, Ewen Mccoll, Philip Preshaw

Peninsula Dental School

The recent article by Lalloo highlighted some of the conflicting challenges faced by universities across the world, particularly the UK. The conclusion drawn in the article related to metrics for ranking dental schools touching on the importance of research to universities: the rankings are biased to research metrics and reputation, rather than the quality of the teaching of oral health professionals.

What Happens After Oil And Gas Decommissioning? A Global Systematic Review Of Marine Environmental Effects, Anaelle Lemasson Lemasson, Antony M. Knights

School of Biological and Marine Sciences

The thousands of oil and gas (OG) platforms placed at sea for fossil fuel extraction have introduced new hard substrate to the marine environment. Over time, these structures can become colonized by a diversity of marine life, fostering novel ecosystems. However, an increasing number of OG platforms are reaching decommissioning age and decisions regarding their fate must be made. Some view these artificial structures as litter that ought to be removed; others view them as valuable contributors to marine biodiversity worth preserving. Evidence of the environmental effects of these structures following different decommissioning strategies is needed to identify the potential …

Cameras Or Divers? How Baited Remote Underwater Videos And ‘Long Swims’ Underwater Visual Census Complement Each Other On Coral Reefs, Kennedy Osuka-Edeye, Melita Samoilys, Bryce D. Stewart, Colin J. Mcclean, Peter Musembi, Saleh Yahya

School of Biological and Marine Sciences

Conventional methods for surveying coral reefs, such as underwater visual census (UVC), often underestimate large-bodied, mobile, or cryptic fish species due to limitations in diver mobility and visual detection. To address these limitations, rapid timed ‘Long Swim’ (LS) UVC protocols have been developed to better capture large predator assemblages, yet their performance relative to baited remote underwater videos (BRUV) remains poorly evaluated in topographically complex oceanic reef environments. This study provides the first site-specific comparison of BRUVS and LS-UVC protocols for predatory reef fish from nine selected families on the reefs of Pemba Island, Tanzania. To ensure robustness, we implemented …

The Diamond Minutes: Rethinking The Earliest Link Of The Trauma Chain Of Survival, Guglielmo Imbriaco, Sonia D’Arrigo, Francesco Limonti, Tim Nutbeam, Alberto Cucino

Peninsula Medical School

Matters arising.Trauma remains one of the leading causes of death worldwide, particularly among children, adolescents, and working-age adults. Despite major advances in trauma system and hospital-based care, a significant proportion of fatalities occur in the prehospital setting, often within minutes and before arrival of emergency medical services (EMS) [1]. Observational analyses consistently suggest that between one quarter and nearly half of trauma-related deaths occur before hospital arrival [2]. A recent prospective multicentre study involving over 1,000 patients with haemorrhagic shock demonstrated that, despite improvements in trauma centre capabilities, including whole blood resuscitation, hybrid operating rooms, and endovascular haemorrhage control, the …

Translating Predictive Models Into Clinical Practice: Fast-And-Frugal Trees For Postoperative Delirium Using Routine Data, Odette Wegwarth, Felix Balzer, Sebastian D. Boie, Niklas Gisa, Anika Müller, Jan K. Woike, Claudia D. Spies, Helge Giese

School of Psychology

Postoperative delirium (POD) is a frequent and serious complication associated with increased morbidity and mortality. Although predictive models for POD exist, they are rarely implemented in routine clinical practice, partly due to their complexity and data requirements. Simple and interpretable tools based on routinely available data may improve clinical applicability. In this retrospective cohort study, we evaluated Fast-and-Frugal Trees (FFTrees) for predicting POD using routine electronic health record data from 61,150 surgical patients treated between 2017 and 2020 at a large German university hospital. We assessed the transferability of previously developed FFTrees and compared their performance with logistic regression, classification …

Investigating The Employability Development Of Tourism And Hospitality Undergraduates In Guizhou, China: A Mixed Methods Study, Jingyu Wu

Plymouth Business School Theses

The rapid expansion of China’s tourism and hospitality (T&H) industry has generated increasing demand for graduates equipped with both professional and transferable skills. Guizhou Province, one of China’s less-developed inland provinces, presents a distinct socio-economic and educational landscape characterised by regional disparities in higher education resources and graduate employment opportunities. As tourism serves as a strategic pillar industry for regional development (National Bureau of Statistics of China, 2024), understanding how students in this southwestern context develop employability is critical for addressing structural inequalities and informing locally responsive higher education policies. This study therefore investigates how tourism and hospitality undergraduates in …

Neural Responses To Acute Hypoxia And Hyperoxia, Daniel Graham, Jonathan Marsden, Alastair D. Smith, Gary Smerdon, Stephen D. Hall

School of Psychology

The brain's high metabolic demands make it highly sensitive to oxygen level changes, with both hypoxia and hyperoxia affecting cognitive and neural function. However, the underlying neural mechanisms remain unclear. This study aimed to characterise the effects of acute normobaric hypoxia and hyperoxia on neural function and perceptual thresholds using EEG, visual evoked potentials (VEPs), and critical flicker fusion (CFF) thresholds. In a single-blind, randomised, crossover design, thirty participants inhaled 10.5%, 21%, or 100% oxygen while resting-state EEG, VEPs, and CFF thresholds were recorded. Hypoxia reduced CFF thresholds in an exposure-dependent manner, while hyperoxia produced a smaller, transient reduction. Resting-state …

Beyond The Evidence: The Cervical Collar As Cultural Artefact, Tim Nutbeam

Peninsula Medical School

Background: Cervical collar application remains prevalent in trauma care despite the absence of evidence of neurological benefit from spinal immobilisation. Clinical behaviour in this area has proven resistant to change, and the persistence of the collar requires explanation beyond the evidential debate alone. The fear of cervical injury has origins that predate clinical practice. Neurobiological preparedness theory suggests that threat associations linked to survival-relevant stimuli are more rapidly acquired and more durably maintained than other learned fears; the cervical region is a plausible candidate for this form of prepared response. This disposition has been reinforced by centuries of cultural practice: …

Residents Vs. Tourists: Understanding The Role Of Coastal Tourism Experience In Conservation Behaviours, Qian Chen, Rong Huang, Jinhua Zhang, Thatsanawalai Imong

Plymouth Business School

This study examines the factors influencing coastal conservation behaviours by integrating the Theory of Planned Behaviour (TPB) with coastal tourism experiences. Conducted in Plymouth, UK, the research assesses how attitudes, subjective norms, perceived behavioural control (PBC), and tourism experiences shape conservation intentions and engagement among residents and tourists. The findings reveal that PBC is the most influential factor associated with conservation intentions in the overall model, while coastal tourism experiences significantly influence engagement, particularly among tourists. Residents' conservation intentions are more influenced by attitudes, whereas tourists are driven by their tourism experiences. These findings highlight the need for tailored conservation …

Advanced Machine Learning Approaches For Bankruptcy Prediction In The Shipping Industry: A Comparative Analysis Across Time Horizons, Minchul Sohn, Saeyeon Roh, Minsu Kwon

Plymouth Business School

This study evaluates machine learning methods for predicting bankruptcies in the Korean shipping industry over 1-, 3-, and 5-year horizons. Using an imbalanced dataset, preprocessing techniques such as outlier capping, skewness correction, and SMOTE-based oversampling are applied. Two feature sets—financial variables and those enriched with macroeconomic and shipping indicators—are analyzed. Results demonstrate that ensemble methods like LightGBM, CatBoost, XGBoost outperform linear models and deep neural networks across all horizons. Short-term predictions are driven by liquidity factors, while long-term forecasts benefit from shipping-specific indices like freight rates. SHAP‐based analysis reveals that internal cash‐flow as critical for one‐year predictions, whereas prolonged freight …

Supporting Commuter Students In Uk Higher Education: Opportunities To Enhance Policy And Practice, Rebecca Turner, Rao Namrata, Christie Pritchard, Oliver Webb, Pinn E, Asal Baharloo, Harriet Ball

Professional Services

Commuter students represent a significant, yet often overlooked, demographic within English higher education (HE). Historically, national policy and institutional practice have failed to adequately acknowledge distinct challenges they face. Using a novel participatory mapping activity, and focus group discussions with 19 commuter students, this paper identifies how commuters are excluded by dominant models of university participation. We examine students’ interactions with campus, peers and staff. Findings reveal how structural norms—such as attendance expectations, financial support, and spatial assumptions—can marginalise learners who do not follow the residential model. Participants described feeling peripheral to university life, with their legitimacy as students sometimes …

Online Simulation To Build Competence In Assessment And Documentation With Clients Experiencing Opioid Use Disorder, Lauren B. Mcinroy, Jacyln Kirsch, Oliver Beer, Katie Klakos, Catherine Hechmer, Julie Holston

School of Health Professions

Synchronous simulation—an experiential learning approach replicating “real-world” practice contexts—offers important opportunities for social work students to apply course concepts, rehearse skills, and increase their competence. However, scant research has considered approaches to delivering synchronous simulation opportunities to students online. This case study examines the experiences of master of social work (MSW) students (n = 52) who participated in a synchronous online simulation activity designed to promote the development of students’ assessment and documentation skills in the context of working with a client with suspected opioid use disorder. Multiple data sources were leveraged, including activity recordings, exit surveys, and submitted materials. …
