Traumatic Brain Injury (TBI) is a major cause of death and disability, leading to great personal suffering to victim and relatives, as well as huge direct and indirect costs to society. Strong ethical, medical, social and health economic reasons therefore exist for improving treatment. The CENTER-TBI project will collect a prospective, contemporary, highly granular, observational dataset of 5400 patients, which will be used for better characterization of TBI and for Comparative Effectiveness Research (CER). The generalisability of our results will be reinforced by a contemporaneous registry level data collection in 15-25,000 patients. Our conceptual approach is to exploit the heterogeneity in biology, care, and outcome of TBI, to discover novel pathophysiology, refine disease characterization, and identify effective clinical interventions. Key elements are the use of emerging technologies (biomarkers, genomics and advanced MR imaging) in large numbers of patients, across the entire course of TBI (from injury to late outcome) and across all severities of injury (mild to severe). Improved characterization with these tools will aid Precision Medicine, a concept recently advocated by the US National Academy of Science, facilitating targeted management for individual patients. Our consortium includes leading experts and will bring outstanding biostatistical and neuroinformatics expertise to the project. Collaborations with external partners, other FP7 consortia, and international links within InTBIR, will greatly augment scientific resources and broaden the global scope of our research. We anticipate that the project could revolutionize our view of TBI, leading to more effective and efficient therapy, thus improving outcome and reducing costs. These outcomes reflect the goals of CER to assist consumers, clinicians, health care purchasers, and policy makers to make informed decisions, and will improve healthcare at both individual and population levels.

To review the use of quality of life (QOL) measures utilised in children and youth with autism spectrum disorder (ASD). Relevant articles were identified through database searches using MEDLINE, CINAHL Plus with Full Text and SPORTDiscus with Full Text via EBSCO Health Database, PsycINFO and ProQuest Health and Medicine (from 2000 to May 2013). Original research articles were included that measured QOL in children and youth with ASD aged 5-20 years. Searches were limited to articles from peer-reviewed journals, in English or German, and those available in full text. The search identified 1,165 titles and 13 met the inclusion criteria. The review identified a number of QOL measures used in children and youth with ASD, with the most common one being the Pediatric Quality of Life Inventory™ (PedsQL). QOL measures using self-reports were uncommon, and the reliability and validity of QOL measures were not sufficiently reported for this population. Large discrepancies in QOL scores were found between self-reports and proxy-reports. Despite the differences in study design and methodological quality, there was consistency in the results among studies; children and youth with ASD provided lower QOL scores, particularly for social domains, compared to their healthy counterparts. The PedsQL is likely to be an appropriate QOL measure for use in children and youth with ASD. Future research should focus on examining the appropriateness, reliability and validity of QOL self-reports for use in this population.

Water, an essential nutrient, is often ignored in reports of dietary surveys and nutrition. Although it is ubiquitous in foods and beverages, the attention is often focused on the minerals or calorific values of the fluids imbibed rather than the water per se. Water is often taken for granted by many in Western countries due to its abundant availability through water systems. In developing countries, however, water and sanitation raise significant problems. This review overviews (i) the global perspective of the potable water supply, (ii) human rights and water, (iii) dietary guidelines and sources of water and (iv) the physiology of water balance. Gaps in knowledge and understanding around hydration and water requirements are also discussed. Nutritionists are urged to look at the bigger picture of the global water supply and to use good judgement and common sense when advising on water requirements. © 2013 Macmillan Publishers Limited.

Spiking neural networks (SNN) are promising artificial neural network (ANN) models as they utilise information representation as trains of spikes, that adds new dimensions of time, frequency and phase to the structure and the functionality of ANN. The current SNN models though are deterministic, that restricts their applications for large scale engineering and cognitive modelling of stochastic processes. This paper proposes a novel probabilistic spiking neuron model (pSNM) and suggests ways of building pSNN for a wide range of applications including classification, string pattern recognition and associative memory. It also extends previously published computational neurogenetic models. © 2009 Elsevier Ltd. All rights reserved.

A point process rainfall model is further developed that has storm origins occurring in space-time according to a Poisson process, where each storm origin has a random radius so that storms occur as circular regions in two-dimensional space, where the storm radii are taken to be independent exponential random variables. Each storm origin is of random type z, where z follows a continuous probability distribution. Cell origins occur in a further spatial Poisson process and have arrival times that follow a Neyman-Scott point process. Each cell origin has a radius so that cells form discs in two-dimensional space, where the cell radii are independent exponential random variables. Each cell has a random lifetime and an intensity that remains constant over both the cell lifetime and cell disk area. Statistical properties up to third order are given for the model. Using these properties, the model is fitted to 10 min series taken from 23 sites across the Rome region, Italy. Distributional properties of the observed annual maxima are compared to equivalent values sampled from series that are simulated using the fitted model. The results indicate that the model will be of use in urban drainage projects for the Rome region. Copyright 2010 by the American Geophysical Union.

A multivariate generalization of the emulator technique described by Hankin (2005) is presented in which random multivariate functions may be assessed. In the standard univariate case (Oakley 1999), a Gaussian process, a finite number of observations is made; here, observations of different types are considered. The technique has the property that marginal analysis (that is, considering only a single observation type) reduces exactly to the univariate theory. The associated software is used to analyze datasets from the field of climate change.

The brain functions as a spatio-temporal information processing machine. Spatio- and spectro-temporal brain data (STBD) are the most commonly collected data for measuring brain response to external stimuli. An enormous amount of such data has been already collected, including brain structural and functional data under different conditions, molecular and genetic data, in an attempt to make a progress in medicine, health, cognitive science, engineering, education, neuro-economics, Brain-Computer Interfaces (BCI), and games. Yet, there is no unifying computational framework to deal with all these types of data in order to better understand this data and the processes that generated it. Standard machine learning techniques only partially succeeded and they were not designed in the first instance to deal with such complex data. Therefore, there is a need for a new paradigm to deal with STBD. This paper reviews some methods of spiking neural networks (SNN) and argues that SNN are suitable for the creation of a unifying computational framework for learning and understanding of various STBD, such as EEG, fMRI, genetic, DTI, MEG, and NIRS, in their integration and interaction. One of the reasons is that SNN use the same computational principle that generates STBD, namely spiking information processing. This paper introduces a new SNN architecture, called NeuCube, for the creation of concrete models to map, learn and understand STBD. A NeuCube model is based on a 3D evolving SNN that is an approximate map of structural and functional areas of interest of the brain related to the modeling STBD. Gene information is included optionally in the form of gene regulatory networks (GRN) if this is relevant to the problem and the data. A NeuCube model learns from STBD and creates connections between clusters of neurons that manifest chains (trajectories) of neuronal activity. Once learning is applied, a NeuCube model can reproduce these trajectories, even if only part of the input STBD or the stimuli data is presented, thus acting as an associative memory. The NeuCube framework can be used not only to discover functional pathways from data, but also as a predictive system of brain activities, to predict and possibly, prevent certain events. Analysis of the internal structure of a model after training can reveal important spatio-temporal relationships 'hidden' in the data. NeuCube will allow the integration in one model of various brain data, information and knowledge, related to a single subject (personalized modeling) or to a population of subjects. The use of NeuCube for classification of STBD is illustrated in a case study problem of EEG data. NeuCube models result in a better accuracy of STBD classification than standard machine learning techniques. They are robust to noise (so typical in brain data) and facilitate a better interpretation of the results and understanding of the STBD and the brain conditions under which data was collected. Future directions for the use of SNN for STBD are discussed. © 2014 Elsevier Ltd.

Determining the factors that have an influence on software systems development and deployment project outcomes has been the focus of extensive and ongoing research for more than 30 years. We provide here a survey of the research literature that has addressed this topic in the period 1996-2006, with a particular focus on empirical analyses. On the basis of this survey we present a new classification framework that represents an abstracted and synthesized view of the types of factors that have been asserted as influencing project outcomes. © 2011 ACM.

Fast decoding algorithms are described for a number of established coded aperture systems. The fast decoding algorithms for all these systems offer significant reductions in the number of calculations required when reconstructing images formed by a coded aperture system and hence require less computation time to produce the images. The algorithms may therefore be of use in applications that require fast image reconstruction, such as near real-time nuclear medicine and location of hazardous radioactive spillage. Experimental tests confirm the efficacy of the fast decoding techniques. © 2014 Elsevier B.V. All rights reserved.

This invention involves use of temporal or spatio/spector-temporal data (SSTD) for early classification of outputs that are results of spatio-temporal patterns of data. Classification models are based on spiking neural networks (SNN) suitable to learn and classify SSTD. The invention may predict early events in many applications, i.e. engineering, bioinformatics, neuroinformatics, predicting response to treatment of neurological and brain disease, ecology, environment, medicine, and economics, among others. The invention involves a method and system for personalized modelling of SSTD and early prediction of events based on evolving spiking neural network reservoir architecture (eSNNr). The system includes a spike-time encoding module to encode continuous value input information into spike trains, a recurrent 3D SNNr and an eSSN as an output classification module.
