Autism is a developmental disorder which presents disability in communication and socialisation and a lack of imagination. To promote creativity, exploration and enjoyment in low functioning autistic children that have no verbal communication, we propose MEDIATE, an interactive environment that generates real time visual, aural and vibrotactile stimuli.(More)
This paper identifies and contextualizes the limitations and problems found in interactive installations that require a massive flux of users. It then presents a set of solutions for these practical problems and shows how they have been applied to a real life installation with exceptionally good results. The application is an interactive water installation(More)
The design of an interactive system for children with severe autism and no verbal communication is one of the most challenging areas a designer of interactive systems can approach; mainly because of the exceptional type of user involved. In fact, this user cannot be typified because autism is not a unique disability but rather a spectrum of disabilities.(More)
The study of the human DNA methylome has gained particular interest in the last few years. Researchers can nowadays investigate the potential role of DNA methylation in common disorders by taking advantage of new high-throughput technologies. Among these, Illumina Infinium assays can interrogate the methylation levels of hundreds of thousands of CpG sites,(More)
Social Networks, as the main axis of Web 2.0, are creating a number of interesting challenges to the research and standardisation communities. In this paper, we analyse the current and future use of access control policies in Social Networks. Subsequently, two main issues are addressed: the interoperability amongst systems using different policy languages(More)
Eating disorders (EDs) are complex psychiatric diseases that include anorexia nervosa and bulimia nervosa, and have higher than 50% heritability. Previous studies have found association of BDNF and NTRK2 to ED, while animal models suggest that other neurotrophin genes might also be involved in eating behavior. We have performed a family-based association(More)
Genomic plasticity of human chromosome 8p23.1 region is highly influenced by two groups of complex segmental duplications (SDs), termed REPD and REPP, that mediate different kinds of rearrangements. Part of the difficulty to explain the wide range of phenotypes associated with 8p23.1 rearrangements is that REPP and REPD are not yet well characterized,(More)
Witch hazel ( Hammamelis virginiana) bark is a rich source of both condensed and hydrolizable oligomeric tannins. From a polyphenolic extract soluble in both ethyl acetate and water, we have generated fractions rich in pyrogallol-containing polyphenols (proanthocyanidins, gallotannins, and gallates). The mixtures were highly active as free radical(More)
The synthesis and characterization of a new radical and its use for testing the antioxidant activity of polyphenols by electron transfer are reported. This new and stable species of magnetic nature, tris(2,3,5,6-tetrachloro-4-nitrophenyl)methyl (TNPTM) radical, has been characterized by electron paramagnetic resonance and its molecular structure determined(More)
