Low-intensity Transcranial Ultrasonic Stimulation (TUS) is a non-invasive brain stimulation technique enabling cortical and deep brain targeting with unprecedented spatial accuracy. Given the high rate of adoption by new users with varying levels of expertise and interdisciplinary backgrounds, practical guidelines are needed to ensure state-of-the-art TUS application and reproducible outcomes. Therefore, the International Transcranial Ultrasonic Stimulation Safety and Standards (ITRUSST) consortium has formed a subcommittee, endorsed by the International Federation of Clinical Neurophysiology (IFCN), to develop recommendations for best practices in human TUS applications. The practical guide presented here provides a brief introduction into ultrasound physics and sonication parameters. It …

Testing The Proteus Effect In Autistic And Neurotypical Participants, Chris Fullwood, Liam Cross, Gray Atherton, Darren Chadwick

School of Psychology

This study examined the Proteus effect in autistic and neurotypical participants via the video game, The Sims. Thirty-two participants (16 autistic, 16 neurotypical) participated in a free-play session of The Sims, playing as either an attractive or unattractive avatar. In line with predictions, participants who had played as the attractive avatar negotiated for a significantly larger share of a fictional pot of money during a post-play economic game. Further, participants who had used the attractive avatar engaged in significantly more exercise activities in-game and flirted more often with nonplayable characters. While there was some evidence to suggest that autistic people …

Gap Filling Crowdsourced Air Temperature Data In Cities Using Data-Driven Approaches, Miao He, Zhiwen Luo, Xiaoxiong Xie, Peng Wang, Haichao Wang, Gabriela Zapata-Lancaster

School of Art, Design and Architecture

Crowdsourced temperature data from citizen weather stations (CWS) in urban area offer valuable insights into intra-urban temperature distribution but are often challenged by a significant number of missing values. Existing gap-filling methods, typically effective for random gaps and low missing rates, are inadequate for the continuous gaps and high missing rates common in CWS recordings. This study introduces a novel data-driven approach to fill these gaps by modelling relationships between CWS data and official weather station (OWS) records during periods of data availability. We evaluate various feature sets and data-driven algorithms, including Multiple Linear Regression (MLR), Random Forest (RF), and …

Early Cretaceous Giant Glendonites: A Record Of (Sub-)Millennial-Scale Cooling?, Madeleine L. Vickers, Mads E. Jelby, Carlette N. Blok, Gregory D. Price, Rhodri M. Jerrett, Maria A. Jensen, Morgan T. Jones

School of Geography, Earth and Environmental Sciences

The Lower Cretaceous succession in Svalbard contains numerous glendonites, pseudomorphs after the cold-water carbonate mineral ikaite, which have been used in conjunction with other evidence to argue for episodic global cooling punctuating the greenhouse climates of the Early Cretaceous. Recent fieldwork in central Spitsbergen has recovered giant bladed glendonites of up to half a metre long, the largest ever recorded in a Lower Cretaceous site, and comparable in size to outlier glendonites found in similar-aged strata of the Sverdrup Basin in Arctic Canada. Unlike the rosette to pineapple-like morphologies seen in some of the largest Canadian Arctic specimens, the new …

Unraveling Algerian Bat Coronaviruses: From Initial Detection To Genome Recovery And Co-Infection Discovery, Safia Zeghbib, Zsófia Tauber, Tamás Görföl, Karimane Malek Zeghbib, Mourad Ahmim, Gábor Kemenesi

School of Biomedical Sciences

IntroductionBats, known as main reservoirs for coronaviruses such as SARS-CoV and SARS-CoV-2, carry these viruses asymptomatically thanks to their unique immune systems. These viruses can spill over to humans through direct contact or intermediate hosts, as observed in the cases of SARS and COVID-19. Despite the significant public health implications, research on bat-related viral zoonoses remains inadequate in Algeria due to insufficient surveillance and funding. Additionally, the ecological diversity of Algerian bats is still largely unexplored, resulting in knowledge gaps. Therefore, investigating bat coronaviruses within the One Health framework in Algeria provides a holistic approach to understanding and mitigating the …

The Feasibility Of Ambulatory Heart Rate Variability Monitoring In Non‐Suicidal Self‐Injury, Rohit Shankar

Peninsula Medical School

The polyvagal theory proposes that the autonomic nervous system influences affective systems and top-down emotional regulation.Vagal tone, as indexed by heart rate variability (HRV), is a measure of emotion regulation capacity. It is possible that non-suicidalself-injury (NSSI) occurs at times of low vagal tone and that NSSI may increase it. Little is known about the feasibility of collectingambulatory HRV data in the context of NSSI. This prospective observational study examined the feasibility of ambulatory HRVmonitoring during NSSI. Ten participants wore a chest-based heart rate monitor and used a diary app for 1 week. Baselinecharacteristics were collected. Heart rate monitoring duration, …

Iegenes: A Machine Learning Method For Selecting Differentially Expressed Genes In Cancer Studies, Xiao-Lei Xia, Shang-Ming Zhou, Yunguang Liu, Na Lin, Ian Overton

School of Nursing and Midwifery

Gene selection is crucial for cancer classification using microarray data. In the interests of improvingcancer classification accuracy, in this paper, we developed a new wrapper method called ieGENES for geneselection. First we proposed a parsimonious kernel machine regularization (PKMR) model by usingridge regularization in kernel machine driven classification to tackle multi-collinearity for the sake of stableestimates in high-dimensional settings. Then the ieGENES algorithm was developed to optimally identifyrelevant genes while iteratively eliminating redundant ones based on leave-one-out cross-validation accuracy.In particular, we developed a new methodology to optimally update model parameters upon gene removal.The ieGENES algorithm was evaluated on six cancer …

For A Decolonial Approach To Game Design Methods Beyond Representation, Rafael Arrivabene

School of Art, Design and Architecture

This article draws attention to game design methods in decolonialist studies. As the importance of systematization in game design starts to become apparent, there is an opportunity to challenge the normalization of values, tropes, and power fantasies that have shaped the industry over the years. The article discusses the ways in which colonialist values permeate recurrent elements of game design, contrasting it with characteristics found in pre-colonial games and how they can be related to indigenous perspectives, which usually do not fit capitalist premises.

Many-Objective Optimisation Of Offshore Wind Farms, Pawel L. Manikowski, Matthew J. Craven, David J. Walker

School of Engineering, Computing and Mathematics

The design of offshore wind farms is computationally challenging, requiring the simultaneous optimisation of many conflicting objectives. Solving this problem is of paramount importance if society is to meet ambitious net zero goals. The problem is solved by identifying an optimal arrangement of individual turbines such that all objectives are optimised. However, a single solution does not exist due to the inherent conflict between objectives, and a set of solutions must be identified. As well as the challenge in generating optimal solution sets, there exists a decision support task if the solutions are to be effectively presented to a decision …

Plymouth Business School

The highest judicial body has recently hit the headlines. In TR v. Land Hessen, the Court of Justice of the EuropeanUnion (CJEU) has clarified the obligations incumbent on a supervisory authority pursuant to the General Data Protection Regulation (GDPR). The CJEU highlights that supervisory authorities are not obliged to exercise ‘corrective’ powers if not necessary to remedy the breach. It clarifies that under the GDPR, supervisory authorities have discretion in addressing the shortcomings of a supervised entity but must ensure compliance with a higher level of data protection.

Better Generalization Through Distraction? Concurrent Load Reduces The Size Of The Inverse Base-Rate Effect, Lenard Dome, Andy J. Wills

School of Psychology

The inverse base-rate effect (IBRE) is an irrational phenomenon in predictive learning. It occurs when people try to generalize what they have experienced to novel and ambiguous events. This irrational generalization manifests as a preference for rare, unlikely outcomes in the face of ambiguity. At least two formal mathematical models of this irrational preference (EXIT, NNRAS) lead to a counter-intuitive prediction: the effect reduces under concurrent load. We tested this prediction across two experiments (N1 = 72, Mage = 20.12; N2 = 160, Mage = 20.88). We confirm the prediction, but only when participants were under an obvious time constraint. …

Peninsula Medical School

More complex surgeries are being performed in increasingly sicker patients, resulting in a greater burden of postoperative morbidity. Delineating the metabolic and bioenergetic changes that occur in response to surgical stress may further our understanding about how humans respond to injury and aid the identification of resilient and frail phenotypes. Skeletal muscle biopsies were taken from patients undergoing hepato-pancreatico-biliary surgery at the beginning and end of the procedure to measure mitochondrial respiration and thiol status. Blood samples were taken at the same timepoints to measure markers of inflammation and systemic redox state. A sub-group of patients underwent cardiopulmonary exercise testing …

Multiphase Modelling Of Electrical Conductivity Of Concrete With Conductive Inclusions, Zaiwei Li, Feiyu Shi, Long Yuan Li

School of Engineering, Computing and Mathematics

Electrical conductivity (EC) of concrete can be effectively improved by incorporating conductive materials such as carbon nanotubes in the mix design. However, mechanism for the EC enhancement to which the addition of conductive materials contributes has not yet been well understood. Besides, either sand or coarse aggregate in concrete also affects the EC of concrete, which complicates understanding of the mechanism. This paper presents a multiphase analytical model to investigate the effect of constituents on the effective EC of concrete. This multi-phase model was developed based on Maxwell model which was modified in this research to consider the effects of …

Post-Traumatic Growth And Influencing Factors Of Parents With Children With Duchenne Muscular Dystrophy: A Cross-Sectional Survey Study, Li Xu, Meili Liu, Yuewei Chen, Liwen Wu, Siyi Gan, Jianhui Xie, Jos M. Latour

School of Nursing and Midwifery

Background: The aim of the study was to identify the post-traumatic growth status and influencing factors of parents with children with Duchenne muscular dystrophy (DMD). Methods: We adopted a cross-section survey study. Between February and December 2022, 181 parents responded to the survey including a participants’ characteristics section, post-traumatic growth assessment scale, caregiver burden scale, and social support assessment scale. Multiple linear regression analysis was used to investigate influencing factors of post-traumatic growth. Results: The mean score of post-traumatic growth of parents was 56.66 (SD ± 18.67). Post-traumatic growth was positively correlated with social support (r = 0.452, P < 0.01) and negatively correlated with care burden (r = -0.207, P < 0.01). Multiple linear regression showed that the child’s age, course of disease, self-care ability, parent’s working condition, residence, education, number of children, and health status were the main influencing factors for the post-traumatic growth of parents (P < 0.001). Conclusion: The post-traumatic growth of parents with children with DMD was at a moderate level. Healthcare professionals should pay attention to the psychological state of parents with children with this rare disease and promote post-traumatic growth through psychological mindfulness interventions, strengthening family and social support, and providing care knowledge and skills.

Future Climate-Driven Habitat Loss And Range Shift Of The Critically Endangered Whitefin Swellshark (Cephaloscyllium Albipinnum), Kerry Brown, Robert Puschendorf

School of Biological and Marine Sciences

Climate change is driving many species to shift their geographical ranges poleward to maintain their environmental niche. However, for endemic species with restricted ranges, like the Critically Endangered whitefin swellshark (Cephaloscyllium albipinnum), endemic to southeastern Australia, such dispersal may be limited. Nevertheless, there is a poor understanding of how C. albipinnum might spatially adjust its distribution in response to climate change or whether suitable refugia exist for this species in the future. Therefore, to address this gap, this study utilised maximum entropy (MaxEnt) modelling to determine the potential distribution of suitable habitat for C. albipinnum under present-day (2010–2020) climate conditions …

School of Engineering, Computing and Mathematics

Tuberculosis is an infectious disease with increasing fatalities around the world. The diagnosis of the diseaseis a major challenge to its control and management due to the lack of adequate diagnostic tools, contributingsignificantly to the prevalence of drug-resistant tuberculosis. Convolutional Neural Network (CNN) modelshave recently been developed to detect drug-resistant tuberculosis by analyzing chest radiograph images fromthe TB portal, but the classification results are low. This is because CNNs struggle to capture complex globaland overlapping features in medical imaging, such as chest radiographs of drug-resistant tuberculosis. Incontrast, transformers excel in these areas by utilizing self-attention mechanisms that detect inherent subtle …

Reward Responses To Vicarious Feeding Depend On Body Mass Index, Lili Järvinen, Severi Santavirta, Vesa Putkinen, Henry K Karlsson, Kerttu Seppälä, Lihua Sun, Matthew Hudson, Jussi Hirvonen, Pirjo Nuutila, Lauri Nummenmaa

School of Psychology

Eating is inherently social for humans. Yet, most neuroimaging studies of appetite and food-induced reward have focused on studying brain responses to food intake or viewing pictures of food alone. We used functional magnetic resonance imaging (fMRI) to measure haemodynamic responses to “vicarious” feeding. The subjects (n = 97) viewed series of short videos representing naturalistic episodes of social eating intermixed with videos without feeding/appetite-related content. Viewing the vicarious feeding (versus control) videos activated motor and premotor cortices, thalamus, and dorsolateral prefrontal cortices, consistent with somatomotor and affective engagement. Responses to the feeding videos were negatively correlated with the participants’ …

Social Comfort And Attractiveness Perception: Impact Of Prosthetics, Physical Disability And Comfort Distance On Interpersonal Interactions, Farid Pazhoohi, Samantha Wing, Alan Kingstone

School of Psychology

Derived from the disease-avoidance model is the hypothesis that people may direct negative cognitive and behavioural responses towards individuals with physical disfiguring conditions, including physical disabilities. According to the behavioral immune system, physical disability—a non-contagious physical disfigurement—may falsely activate cognitive disease-avoidance processes, resulting in prejudicial or negative responses toward individuals with physical disabilities. For the first time this hypothesis is put to the test by investigating whether ratings of attractiveness and comfort for a social interaction vary systematically with physical disability (Studies 1 and 2). In addition, we tested whether these ratings were associated with individual differences in pathogen disgust …
