Emotive Immersion: Eeg-Driven Ai Art In Immersive Visual Spaces (Full Dome), Yuming Chen, Gianni Corino

School of Art, Design and Architecture

This paper proposes a rethinking of the “Future Screen” through the integration of affective computing, generative AI, and immersive spatial display. As an advanced screen paradigm, the full dome environment transcends flat, passive interfaces and enables dynamic, multisensory, and emotionally adaptive media experiences (Von Chamier-Waite, 2013). Building on this potential, the research presents Coids, an interactive dome installation. In this work, real-time emotional states are captured using EEG-based emotion recognition. These inputs dynamically shape AI-generated visuals within a shared immersive setting.Drawing on theories of immersion, presence, AI generated visuals and affect, the study explores how physiological data, even from low-resolution …

Volumetric Video With Skateboarders: Creative Opportunities Of Working With An Emerging Screen Technology Beyond The Studio, Dani Landau, Diego Zamora Dec 2025

Volumetric Video With Skateboarders: Creative Opportunities Of Working With An Emerging Screen Technology Beyond The Studio, Dani Landau, Diego Zamora

School of Art, Design and Architecture

Volumetric video is an emerging moving image technology in which each pixel is recorded witha location in three dimensions. Volumetric videos are normally created in studios using rigs made upof multiple cameras with LiDAR sensors and computers that combine the moving images. We tookthis technology out of the studio to explore variations of this technique in public skateparks. We foundthat as the technology is still in developing stages there are creative constraints: the lidar cameras sense at a limited distance to the subject, the image is of a relatively low resolution, and there are often glitches in theimage. In our …

Investigating The Potential Of Time-Varying Free Parameters In Equilibrium Shoreline Change Models Through Data Assimilation, Georgios Azorakos, Bruno Castelle, Déborah Idier, Vincent Marieu, Raimundo Ibaceta, Kristen D. Splinter, Stéphane Bertin, Gerd Masselink, Timothy Scott

School of Biological and Marine Sciences

Equilibrium shoreline change models with calibrated, time-invariant free parameters have demonstrated good skill in hindcasting shoreline evolution at sites dominated by cross-shore sediment transport. However, their performance can be biased by the specific conditions present during the calibration period. In this study, a dual parameter-state ensemble Kalman filter (EnKF) was applied to track non-stationarity in model free parameters at three sites along the west coast of Europe. Introducing time-varying parameters did not substantially improve performance relative to an already well-calibrated stationary model. Model skill improvement occurred mainly during the EnKF correction step, highlighting the potential of real-time data assimilation for …

Leveraging Transcranial Ultrasound Stimulation To Enhance Self-Regulation In Emotion And Sleep, Suraya Dunsford, Mica Komarnyckyj, Elsa Fouragnan Dec 2025

Leveraging Transcranial Ultrasound Stimulation To Enhance Self-Regulation In Emotion And Sleep, Suraya Dunsford, Mica Komarnyckyj, Elsa Fouragnan

School of Psychology

This Perspective article discusses the emerging potential of transcranial ultrasound stimulation (TUS) as a non-invasive neuromodulatory technique for enhancing self-regulatory processes, particularly emotion and sleep regulation, in healthy individuals. Offering high spatial precision and the ability to target both cortical and deep brain regions, TUS uses focused ultrasound waves to induce acute and delayed effects on brain activity. We propose that combining TUS with neurofeedback methods and/or specific cognitive training exercises may capitalise on these neuroplastic effects, thereby augmenting and prolonging their impact to support lasting improvements in self-regulation. We focus on the domains of sleep and emotion regulation, where …

School of Biological and Marine Sciences

To identify nanomaterials of potential environmental concern and to support risk assessment for regulatory purposes bioaccumulation testing is required. However, further guidance is needed when applying the fish bioaccumulation OECD test guideline (TG) No. 305 to nanomaterials. Also questions remain surrounding the most appropriate exposure route and if subtle modifications to these materials (e.g. different coatings) will influence bioaccumulation potential. Therefore in this study OECD TG 305 was applied to assess the bioaccumulation potential of CdTe quantum dots (QDs) with additional considerations for testing nanomaterials. CdTe QDs were selected for our studies because of their increasing use, possible release to …

School of Geography, Earth and Environmental Sciences

Measurements of pre-industrial conditions are of paramount importance for understanding historical climate change. The Southern Ocean and Antarctic continent are some of the least polluted environments on planet Earth. Alkylamines can rapidly partition into aerosols, increasing their mass, as well as form new particles altogether. We demonstrate the importance of pelagic “open ocean” (OO) and sympagic “sea ice” (SI) regions in supplying distinct organic nitrogen aerosol components. In the aerosol phase, dimethylamine (DMA) and trimethylamine (TMA) are both secondary, though DMA likely originates mainly from pelagic regions, while TMA is associated mainly with sympagic regions. Parallel measurements in ice and …

School of Engineering, Computing and Mathematics

Alzheimer’s Disease (AD) is one of the most commonly seen neurodegenerative disorders, where early detection of its biomarkers is crucial for effective management. Conventional diagnostic methods are often expensive, time-consuming, and highly complex, which highlights an urgent need for point-of-care biosensing technology. In this work, we developed assays on three-dimensional (3D) graphene foam electrodes by functionalising them with a 1-Pyrenebutyric acid N-hydroxysuccinimide ester (Pyr-NHS) to enable effective antibody immobilisation for the detection of amyloid beta peptides (Aβ42 and Aβ40), key biomarkers for AD. Pyr-NHS linkers were used for stable functionalisation, followed by binding with Aβ42 and Aβ40 antibodies, and then …

Artem-Is For Erp: Agreed Reporting Template For Eeg Methodology-International Standard For Event-Related Potential Experiments, Giorgio Ganis

School of Psychology

The choices we make during the recording, preprocessing and analysis of event-related potentials (ERP) data can affect study outcomes. As such, it is critical that they are transparently reported to allow for reproducibility. Yet, systematic reviews of reporting practices in the field have shown that journal articles often do not meet this goal and that existing reporting guidelines have not resulted in a sufficient improvement in reporting transparency. An easier workflow for transparently documenting pipelines used in regular journal articles is needed. The ARTEM-IS (Agreed Reporting Template for EEG Methodology—International Standard) initiative is working towards addressing this issue by building …

Effects Of Maternal Hypoxia On Developmental Plasticity, Matilda Powell Dec 2025

Effects Of Maternal Hypoxia On Developmental Plasticity, Matilda Powell

The Plymouth Student Scientist

Developmental plasticity enables organisms to adjust phenotypes to environmental cues, yet the transgenerational consequences of maternal effects remain unclear. Hypoxia, intensified by climate change and eutrophication, triggers taxon-specific plastic responses. Daphnia magna exhibits plasticity dependence, making it a critical model species for studying environmental responses. While maternal hypoxia (MH) influences generational plasticity, its long-term impacts on reproductive and physiological traits across generations remain insufficiently explored, limiting predictions of species resilience to environmental change. This study employed a controlled two-generation design: gravid F0 adults were exposed to moderate hypoxia (40% air saturation) or normoxia (100% AS) for 8 days, with reproductive …
