Approximately 30-50% of the >30 million HIV-infected subjects develop neurological complications ranging from mild symptoms to dementia. HIV does not infect neurons, and the molecular mechanisms behind HIV-associated neurocognitive decline are not understood. There are several hypotheses to explain the development of dementia in HIV(+) individuals,(More)
In previous work we have developed a new hybrid approach for handling ill-shaped elements possibly appearing after cutting simulation meshes. In this work we compare the approach with existing standard techniques commonly employed to treat topological changes in deformation meshes. Our results indicate that the hybrid approach might be better suited for(More)
This paper describes a reference architecture to support a multiuser virtual communication platform that enables rehabilitation and social integration of Down's Syndrome children. The platform, based on an on-line virtual collaborative environment supported by the World Wide Web, includes collaboration and interpersonal communication devices and data(More)
Despite the recent advances in antiretroviral therapy, human immunodeficiency virus type 1 (HIV-1) remains a global health threat. HIV-1 affects the central nervous system by releasing viral proteins that trigger neuronal death and neuroinflammation, and promotes alterations known as HIV-associated neurocognitive disorders (HAND). This disorder is not fully(More)
This paper presents an approach for managing a synthetic model of culture based on the cognitive processes that allow humans to display culturally biased behaviors. We present cognitive agents as the underlying methodology for simulating such processes, introducing their main capabilities and using them to simulate the main processes involved in culture(More)
