The study of natural and artificial phenomena generates massive amounts of data in many areas of research. This data is frequently left unused due to the lack of tools to effectively extract, analyze and understand it. Visual representation techniques can play a key role in helping to discover patterns and meaning within this data. Neuroscience is one of(More)
—Cybercrime tackling is a major challenge for Law Enforcement Agencies (LEAs). Traditional digital forensics and investigation procedures are not coping with the sheer amount of data to analyse, which is stored in multiple devices seized from distinct, possibly-related cases. Moreover, inefficient information representation and exchange hampers evidence(More)
Phacomatosis pigmentovascularis is a rare syndrome characterized by the coexistence of a pigmented nevus and a cutaneous vascular malformation. We report a 5-year-old boy with all the typical findings of phacomatosis pigmentovascularis type Ia. Although its existence according to the traditional classification has been questioned, this case represents a(More)

She was started on empirical antibiotic therapy with ciprofloxacin (750 mg twice daily) and insulin. Dermatologi-cal observation was required 48 hours later due to a rash that had been evolving for 24 hours. Physical examination revealed a bilateral(More)
Objective: To compare the stride frequency, length, and duration, as well as the horizontal speed and the walking's ratio, in three intensities of displacement (ID) levels between subjects with and without nonspecific chronic low back pain (NCLBP). Methods: The sample was composed by volunteers with NCLBP, (LG/n=6) and healthy subjects (CG/n=7). The(More)
Dance performance interconnects the notion of space and movement, providing therefore the ideal framework to design and research immersive relations between the virtual and physical world: mixed reality performance. We start by discussing conceptual approaches to immersive and mixed reality environments, and reporting some of the current state of the art(More)
Methylmethacrylate was first reported in 1941 as a cause of contact dermatitis. Since then, occupational contact allergies to acrylates in dentistry, orthopedic surgery, printing industry and industry have been reported, but few reports are found in the literature as a consequence of the contact with sculptured artificial acrylic nails which are(More)
Research based academic start-ups have became an important aspect of the technology transfer process. The emergence of an entrepreneurial university brought a new scenario where many ventures are settle up by researches in order to exploit commercially the out puts of research activity. What are the main characteristics of this companies? What resources and(More)
