This paper outlines the use of a relational representation in a Multi-Agent domain to model the behaviour of the whole system. The aim of this work is to define a general systematic method to verify the effective collaboration among the members of a team and to compare the different multi-agent behaviours, using external observations of a Multi-Agent System. Observing and analysing the behavior of a such system is a difficult task. Our approach allows to learn sequential behaviours from raw multi-agent observations of a dynamic, complex environment, represented by a set of sequences expressed in first-order logic. In order to discover the underlying knowledge to characterise team behaviours, we propose to use a relational learning algorithm to mine meaningful frequent patterns among the relational sequences. We compared the performance of two soccer teams in a simulated environment, each based on very different behavioural approaches: While one uses a more deliberative strategy, the other one uses a pure reactive one

LABEC, the INFN ion beam laboratory of nuclear techniques for environment and cultural heritage

The LABEC laboratory, the INFN ion beam laboratory of nuclear techniques for environment and cultural heritage, located in the Scientific and Technological Campus of the University of Florence in Sesto Fiorentino, started its operational activities in 2004, after INFN decided in 2001 to provide our applied nuclear physics group with a large laboratory dedicated to applications of accelerator-related analytical techniques, based on a new 3 MV Tandetron accelerator. The new accelerator greatly improved the performance of existing Ion Beam Analysis (IBA) applications (for which we were using since the 1980s an old single-ended Van de Graaff accelerator) and in addition allowed to start a novel activity of Accelerator Mass Spectrometry (AMS), in particular for 14C dating. Switching between IBA and AMS operation became very easy and fast, which allowed us high flexibility in programming the activities, mainly focused on studies of cultural heritage and atmospheric aerosol composition, but including also applications to biology, geology, material science and forensics, ion implantation, tests of radiation damage to components, detector performance tests and low-energy nuclear physics. This paper describes the facilities presently available in the LABEC laboratory, their technical features and some success stories of recent applications

Olfactory function in systemic lupus erythematosus and systemic sclerosis: a longitudinal study and review of the literature

To evaluate olfactory function in systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and healthy controls over a 2-year period, and to determine the association of olfactory dysfunction with age, disease activity, disease damage, treatment, anxiety and depression symptoms and limbic structures volumes. Consecutive SLE and SSc patients were enrolled in this study. Clinical, laboratory disease activity and damage were assessed according to diseases specific guidelines. Olfactory functions were evaluated using the Sniffin' Sticks test (TDI). Volumetric magnetic resonance imaging (MRI) was obtained in a 3T Phillips scanner. Amygdalae and hippocampi volumes were analyzed using FreeSurfer® software. We included 143 SLE, 57 SSc and 166 healthy volunteers. Olfactory dysfunction was observed in 78 (54.5%) SLE, 35 (59.3%) SSc patients and in 24 (14.45%) controls (p < 0.001) at study entry. SLE and SSc patients had significantly lower mean in all three phases (TDI) of the olfactory assessment when compared with healthy volunteers. In SLE, the presence of olfactory dysfunction was associated with older age, disease activity, higher anxiety and depression symptoms score, smaller left hippocampus volume, smaller left and right amygdalae volume and the presence of anti-ribosomal P (anti-P) antibodies. In SSc the presence of olfactory impairment was associated with older age, disease activity, smaller left and right hippocampi volumes and smaller right amygdala volume. Olfactory function was repeated after a 2-year period in 90 SLE, 35 SSc and 62 controls and was stable in all three groups. Both SLE and SSc patients with longstanding disease had significant reduction in all stages of TDI that maintained stable over a 2-year period. Olfactory dysfunction was associated with age, inflammation and hippocampi and amygdalae volumes. In SLE, additional association with anti-P, anxiety and depression symptoms was observed17440541
