Is Information Provided Within Chronic Subdural Haematoma Education Resources Adequate? A Scoping Review, Conor S. Gillespie, Samuel Khanna, Mark E. Vivian, Samuel Mckoy, Touzet A Yanez, Ellie Edlmann, Daniel J. Stubbs, Benjamin M. Davies

Peninsula Medical School

Background Chronic subdural haematoma (CSDH) is becoming increasingly prevalent, due to an aging population with increasing risk factors. Due to its variable disease course and high morbidity, patient centred care and shared decision making are essential. However, its occurrence in frail populations, remote from specialist neurosurgeons who currently triage treatment decisions, challenges this. Education is an important component of enabling shared decisions. This should be targeted to avoid information overload. However, it is unknown what this should be. Objectives Our objectives were to conduct analysis of the content of existing CSDH educational materials, to inform the development of patient and …

School of Nursing and Midwifery

The analysis of Electroencephalography (EEG) signals has been an effective way of eye state identification. Its significance is highlighted by studies that examined the classification of eye states using machine learning techniques. In previous studies, supervised learning techniques have been widely used in EEG signals analysis for eye state classification. Their main goal has been the improvement of classification accuracy through the use of novel algorithms. The trade-off between classification accuracy and computation complexity is an important task in EEG signals analysis. In this paper, a hybrid method that can handle multivariate signals and non-linear is proposed with supervised and …

A Core Outcome Set For Childhood Epilepsy Treated With Ketogenic Diet Therapy ( Core‐Kdt Study): International Parent And Health Professional Consensus: International Parent And Health Professional Consensus, Jennifer H. Carroll, J. Helen Cross, Mary Hickson, Emma Williams, Val Aldridge, Avril Collinson

School of Health Professions

OBJECTIVE: Ketogenic diet therapy (KDT) can result in benefits (seizure and non-seizure related) for children with drug resistant epilepsy. However, clinical trials report a wide range of outcomes making synthesis of evidence difficult, and do not adequately reflect parent views on important outcomes for their child. To address this, we established the first international parent, health professional and researcher consensus to develop a core outcome set, guided by the Core Outcome Measures in Effectiveness Trials (COMET) Initiative (COMET registration #1116). METHODS: Ethical approval was granted (London-Surrey REC19/LO/1680). A scoping review and interviews with parents identified a comprehensive list of potentially …

Queer Psycho And The He Circus: Applying Queering, Magic, And More-Than-Human Theories To Immersive Visual Story Worlds As An Antidote To Late Capitalism, Eleanor Dare, Dylan Yamada-Rice Mar 2023

Queer Psycho And The He Circus: Applying Queering, Magic, And More-Than-Human Theories To Immersive Visual Story Worlds As An Antidote To Late Capitalism, Eleanor Dare, Dylan Yamada-Rice

School of Art, Design and Architecture

Abstract Two immersive visual story worlds (IVS), Queer Psycho and HE Circus, are at the center of this article, one made by each of us. Individually we found our works necessitated the development of new frameworks for IVS construction, namely (1) Brechtian a-effect and queering, and (2) magic and more-than-human theories. These new framings were needed to realize our desire to use IVS to create spaces of active resistance from psychological harm imposed by political and ableist structures designed with rigid ways of seeing the world through straight/neoliberal lenses. When both story worlds and their frameworks are viewed side-by-side, they …

Animals Other Than Human Animals And Their Claim To Equal Consideration In Coronavirus And Criminological Study: Examining Harm To Domesticated Dogs During Covid-19 In The Uk, Rebekah Kim Gregory

School of Law, Humanities and Social Sciences

While the financial and social support afforded to United Kingdon (UK) ‘animals other than human animals’ (AOTHAs) welfare charities, such as the RSPCA and Dogs Trust, could suggest that they are valued intrinsically within Western society criminological texts largely omit them from recognition, with some important exceptions, see non-speciesist criminology. Most human animals likely do not want to directly or indirectly harm AOTHAs and even value relationships with “companion” AOTHAs. Regardless, AOTHAs have been victimized throughout history and continue to be. This article examines harm to AOTHAs in the context of the global COVID-19 pandemic to argue that abuse proliferates …

Ocean Acidification Increases The Impact Of Typhoons On Algal Communities, Callum J. Hudson, Sylvain Agostini, Shigeki Wada, Jason M. Hall-Spencer, Sean D. Connell, Ben P. Harvey

School of Biological and Marine Sciences

Long-term environmental change, sudden pulses of extreme perturbation, or a combination of both can trigger regime shifts by changing the processes and feedbacks which determine community assembly, structure, and function, altering the state of ecosystems. Our understanding of the mechanisms that stabilise against regime shifts or lock communities into altered states is limited, yet also critical to anticipating future states, preventing regime shifts, and reversing unwanted state change. Ocean acidification contributes to the restructuring and simplification of algal systems, however the mechanisms through which this occurs and whether additional drivers are involved requires further study. Using monthly surveys over three …

The Influence Of Mantle Hydration And Flexure On Slab Seismicity In The Southern Central Andes, C Rodriguez Piceda, Y-J Gao, M Cacace, M Scheck-Wenderoth, J Bott, M Strecker, F Tilmann

School of Geography, Earth and Environmental Sciences

Knowledge of the causative dynamics of earthquakes along subduction-zone interfaces and within oceanic slabs is relevant for improving future seismic hazard assessments. Here, we combine the analysis of seismic tomography, the 3D structure of the slab and seismicity to investigate the controlling factors driving slab seismic activity beneath the southern Central Andes. We evaluate the ratio distribution between compressional and shear-wave seismic velocities (Vp/Vs) as a proxy for the hydration state of the lithospheric mantle, oceanic slab, and plate interface. Regions of high Vp/Vs, i.e. areas of hydrated mantle, are principally caused by compaction effects and dehydration reactions. In contrast, …

Passivity-Based Trajectory Tracking And Formation Control Of Nonholonomic Wheeled Robots Without Velocity Measurements, Ningbo Li, Pablo Borja, Jacquelien M.A. Scherpen, Avd Schaft, Robert Mahony Mar 2023

Passivity-Based Trajectory Tracking And Formation Control Of Nonholonomic Wheeled Robots Without Velocity Measurements, Ningbo Li, Pablo Borja, Jacquelien M.A. Scherpen, Avd Schaft, Robert Mahony

School of Engineering, Computing and Mathematics

This note proposes a passivity-based control method for trajectory tracking and formation control of nonholonomic wheeled robots without velocity measurements. Coordinate transformations are used to incorporate the nonholonomic constraints, which are then avoided by controlling the front end of the robot rather than the center of the wheel axle into the differential equations. Starting from the passivity-based coordination design, the control goals are achieved via an internal controller for velocity tracking and heading control and an external controller for formation in the port-Hamiltonian framework. This approach endows the resulting controller with a physical interpretation. To avoid unavailable velocity measurements or …

Real-Time Hybrid Testing Of A Floating Offshore Wind Turbine Using A Surrogate-Based Aerodynamic Emulator, E Ransley, S Brown, E Edwards, T Tosdevin, K Monk, A Reynolds, D Greaves, M Hann

School of Engineering, Computing and Mathematics

Physical modeling of floating offshore wind turbines (FOWTs) is challenging due to the complexities associated with the simultaneous application of two different scaling laws, governing the hydrodynamic and aerodynamic loading on the structure. To avoid these issues, this paper presents a real-time hybrid testing (RTHT) strategy in which a feedback loop, consisting of an on-board fan and control algorithm, is utilized to emulate the aerodynamic forces acting on the FOWT system. Here, we apply this strategy to a 70th-scale IEA Wind 15 MW reference wind turbine mounted on a version of the VolturnUS-S platform. Unlike other similar methods, which directly …
