Semantic memory decline has been found in mild cognitive impairment (MCI). In this study performance on a range of semantic tasks and structural brain patterns were examined in a group of MCI patients. Fourteen MCI and sixteen healthy elderly controls underwent semantic memory assessment and MRI brain scanning. The cognitive battery included visual naming(More)
Vitality form is a term that describes the style with which motor actions are performed (e.g., rude, gentle, etc.). They represent one characterizing element of conscious and unconscious bodily communication. Despite their importance in interpersonal behavior, vitality forms have been, until now, virtually neglected in neuroscience. Here, using the(More)
In this work we present a prototype system aimed at extracting contents from online communities discussions and publishing them through aggregated RSS feeds. The major foreseeable impact of this project to the Community Informatics field will be helping people to manage the complexity intrinsic in dealing with the huge amount of dynamic information produced(More)
Semantic memory decline and changes of default mode network (DMN) connectivity have been reported in mild cognitive impairment (MCI). Only a few studies, however, have investigated the role of changes of activity in the DMN on semantic memory in this clinical condition. The present study aimed to investigate more extensively the relationship between(More)
We present the new release of the ORAC engine (Procacci et al., Comput Chem 1997, 18, 1834), a FORTRAN suite to simulate complex biosystems at the atomistic level. The previous release of the ORAC code included multiple time steps integration, smooth particle mesh Ewald method, constant pressure and constant temperature simulations. The present release has(More)
This article presents a new ab initio force field for the cofactors of bacterial photosynthesis, namely quinones and bacteriochlorophylls. The parameters has been designed to be suitable for molecular dynamics simulations of photosynthetic proteins by being compatible with the AMBER force field. To our knowledge, this is the first force field for(More)
We describe a modified Grid architecture that allows to specify and enforce connection policies with preferences and integrity constraints. This is done by interposing a policy enforcement engine between a calling application and the relative client stubs. Such policies are conveniently expressed in the declarative policy specification language PPDL. In(More)
We propose a software architecture for semantics-based annotation of data extracted from Web sources. Starting from the LiXto suite, which enables semi-automated extraction of XML data from regular documents, we present a solution for attaching background information to individual tags by means of so-called decorations. Decoration is carried out as an(More)
