Performance measurements of a pilot superconducting solenoid model core for a wind tunnel magnetic suspension and balance system

The results of experimental demonstrations of a superconducting solenoid model core in the Southampton University Magnetic Suspension and Balance System are detailed. Technology and techniques relevant to large-scale wind tunnel MSBSs comprise the long term goals. The magnetic moment of solenoids, difficulties peculiar to superconducting solenoid cores, lift force and pitching moment, dynamic lift calibration, and helium boil-off measurements are discussed

Using high resolution displays for high resolution cardiac data

The ability to perform fast, accurate, high resolution visualization is fundamental to improving our understanding of anatomical data. As the volumes of data increase from improvements in scanning technology, the methods applied to rendering and visualization must evolve. In this paper we address the interactive display of data from high resolution MRI scanning of a rabbit heart and subsequent histological imaging. We describe a visualization environment involving a tiled LCD panel display wall and associated software which provide an interactive and intuitive user interface. The oView software is an OpenGL application which is written for the VRJuggler environment. This environment abstracts displays and devices away from the application itself, aiding portability between different systems, from desktop PCs to multi-tiled display walls. Portability between display walls has been demonstrated through its use on walls at both Leeds and Oxford Universities. We discuss important factors to be considered for interactive 2D display of large 3D datasets, including the use of intuitive input devices and level of detail aspects

Facing Shadows: working with young people to coproduce a short film about depression

Background: IMPACT (Improving Mood with Psychoanalytic and Cognitive Therapies) is a multi-centre randomised controlled trial of three therapeutic interventions for the treatment of depression in young people. IMPACT- My Experience (IMPACT-ME), a qualitative research study, followed up a sub-sample of families involved in IMPACT to explore young people's experiences of therapy and depression. Members of the IMPACT-ME steering group, who brought their own experiences of depression and engaging with mental health services, were keen to find ways to provide information about depression and help-seeking beyond traditional academic audiences, specifically to other young people experiencing depression and wondering where to turn: their chosen medium was film. Here we describe and reflect on the four-day coproduction workshops in which researchers, young people and film-makers coproduced 'Facing Shadows', a short animation about depression and therapy (https://www.youtube.com/watch?v=LdmRPKUhNEY). Main body: We outline the process, focusing on the four-day creative, collaborative workshop in which young people shared their experiences, decided on the tone, tenor and message of the film, identified their primary audience and produced the bulk of the audio and visual material. The adults acted as facilitators: developing a creative, collaborative learning environment in which trusting relationships could flourish, as well as offering guidance, instruction, advice and support. To date the film has been viewed around 12,000 times on YouTube. The young people learned new skills, felt listened to and enjoyed the process. They produced a film which sends a hopeful message to other young people, '… that they are not alone'. Conclusion: We reflect on the creative participatory workshop approach which transformed the project from dissemination to an insightful learning experience for young people and researchers alike

Mathematical Modelling of Chemical Diffusion through Skin using Grid-based PSEs

A Problem Solving Environment (PSE) with connections to remote distributed Grid processes is developed. The Grid simulation is itself a parallel process and allows steering of individual or multiple runs of the core computation of chemical diffusion through the stratum corneum, the outer layer of the skin. The effectiveness of this Grid-based approach in improving the quality of the simulation is assessed

Adaptive high-order finite element solution of transient elastohydrodynamic lubrication problems

This article presents a new numerical method to solve transient line contact elastohydrodynamic lubrication (EHL) problems. A high-order discontinuous Galerkin (DG) finite element method is used for the spatial discretization, and the standard Crank-Nicolson method is employed to approximate the time derivative. An h-adaptivity method is used for grid adaptation with the time-stepping, and the penalty method is employed to handle the cavitation condition. The roughness model employed here is a simple indentation, which is located on the upper surface. Numerical results are presented comparing the DG method to standard finite difference (FD) techniques. It is shown that micro-EHL features are captured with far fewer degrees of freedom than when using low-order FD methods

Cortical thickness gradients in structural hierarchies.

MRI, enabling in vivo analysis of cortical morphology, offers a powerful tool in the assessment of brain development and pathology. One of the most ubiquitous measures used-the thickness of the cortex-shows abnormalities in a number of diseases and conditions, but the functional and biological correlates of such alterations are unclear. If the functional connotations of structural MRI measures are to be understood, we must strive to clarify the relationship between measures such as cortical thickness and their cytoarchitectural determinants. We therefore sought to determine whether patterns of cortical thickness mirror a key motif of the cortex, specifically its structural hierarchical organisation. We delineated three sensory hierarchies (visual, somatosensory and auditory) in two species-macaque and human-and explored whether cortical thickness was correlated with specific cytoarchitectural characteristics. Importantly, we controlled for cortical folding which impacts upon thickness and may obscure regional differences. Our results suggest that an easily measurable macroscopic brain parameter, namely, cortical thickness, is systematically related to cytoarchitecture and to the structural hierarchical organisation of the cortex. We argue that the measurement of cortical thickness gradients may become an important way to develop our understanding of brain structure-function relationships. The identification of alterations in such gradients may complement the observation of regionally localised cortical thickness changes in our understanding of normal development and neuropsychiatric illnesses.We thank Claus Hilgetag and Sarah Beul for valuable input and Helen Barbas for providing macaque data.

Eyes on the bog. Long-term monitoring network for UK peatlands

Eyes on the Bog provides a scientifically robust, repeatable, low tech, long-term monitoring initiative. The standardised methodology enables individual peatland sites to be consistently monitored across the UK, creating a network of comparable sites. The initiative employs cheap, simple techniques and modern technology to enable useful monitoring information to be collected by peatland community employees or volunteers on: Peat subsidence and carbon loss Carbon capture Water table behaviour Peat soil condition Vegetation status, structure and composition Historical context of change and current trajectorie

Psychopathic traits influence amygdala-anterior cingulate cortex connectivity during facial emotion processing

There is accumulating evidence that youths with antisocial behavior or psychopathic traits show deficits in facial emotion recognition, but little is known about the neural mechanisms underlying these impairments. A number of neuroimaging studies have investigated brain activity during facial emotion processing in youths with Conduct Disorder (CD) and adults with psychopathy, but few of these studies tested for group differences in effective connectivity – i.e., changes in connectivity during emotion processing. Using functional magnetic resonance imaging and psycho-physiological interaction methods, we investigated the impact of CD and psychopathic traits on amygdala activity and effective connectivity in 46 male youths with CD and 25 typically-developing controls when processing emotional faces. All participants were aged 16-21 years. Relative to controls, youths with CD showed reduced amygdala activity when processing angry or sad faces relative to neutral faces, but the groups did not significantly differ in amygdala-related effective connectivity. In contrast, psychopathic traits were negatively correlated with amygdala-ventral anterior cingulate cortex connectivity for angry versus neutral faces, but were unrelated to amygdala responses to angry or sad faces. These findings suggest that CD and psychopathic traits have differential effects on amygdala activation and functional interactions between limbic regions during facial emotion processing

Adolescents leaving mental health or social care services: predictors of mental health and psychosocial outcomes one year later.

BACKGROUND: UK service structure necessitates a transition out of youth services at a time of increased risk for the development and onset of mental disorders. Little is currently known about the mental health and psychosocial outcomes of leaving services at this time. The aim of this study was to determine predictors of mental health and social adjustment in adolescents leaving mental health or social care services. METHODS: A cohort (n = 53) of 17 year olds were interviewed and assessed when preparing to leave adolescent services and again 12 months later. Their mental health and psychosocial characteristics were compared to a same-age community sample group (n = 1074). RESULTS: At discharge 34 (64%) met DSM IV criteria for a current psychiatric diagnosis and only 3 (6%) participants met operational criteria for successful outcomes at follow-up. Impairments in mental health, lack of employment, education or training and low preparedness were associated with poor outcomes. CONCLUSIONS: The findings suggest the current organisation of mental health and care services may not be fit for purpose and even unwittingly contribute to persistent mental illness and poor psychosocial outcomes. A redesign of services should consider a model where the timing of transition does not fall at the most hazardous time for young people, but is sufficiently flexible to allow young people to move on when they are personally, socially and psychologically most able to succeed. Assessment of a young person's readiness to transition might also be useful. A youth focused service across the adolescent and early adult years may be better placed to avoid young people falling through the service gap created by poor transitional management.This work was completed within the NIHR Collaborations for Leadership in Applied Health Research and Care (CLAHRC) for Cambridgeshire and Peterborough (now CLAHRC East of England).

Imagining your child's mind: psychosocial adjustment and mothers' ability to predict their children's attributional response styles

One class of parent-child interaction that has recently received attention is maternal engagement with her child at a mental level. The current study operationalises this notion by asking the mothers of 354 7-11 year old children drawn from a larger community sample (n=659) to guess the responses of their children, who in turn, were asked to attribute thoughts to their peers in distressing peer-related scenarios. The following predictions were made: (1) mothers would be above chance in the accuracy by which they predicted their children’s overal attributional styles (2) increased maternal accuracy would be an important correlate of reduced psychopathology symptoms in children; and (3) poor maternal accuracy would associated with a maladaptive child attributional response style characterised by unrealistic and overly positive attributions. Results suggested that maternal accuracy was normally distributed with mothers accurately guessing the responses of their children for about half of the social scenarios. Mothers were furthermore shown to be above chance in the accuracy by which they predicted their children's overall attributional styles. Maternal accuracy was found to be related to child psychosocial adjustment (reduced scores on child psychopathology measures), whilst poor maternal accuracy was associated with ineffective social-cognitive reasoning, as indexed by an unrealistic and overly positive child attributional style. Findings are discussed within the context of the burgeoning literature linking attachment, family talk about feelings and thoughts and parental mind-mindedness
