In this paper, we briefly describe recent research directions of the Artificial Intelligence group of the University of L'Aquila, Italy. Research activities concern Computational Logic and mainly Intelligent Logical Agents. In fact, in the last years the group has developed the logical agent-oriented language DALI. However, work is under way also in other areas, like, e.g., Non-Monotonic Reason...

The effects of the bleaching herbicide amitrole on the carotenoid composition and ultrastructure were studied du­ ring the transformation of chloroplasts into chromoplasts in the tulip tree (Liriodendron tulipifera L.). Amitrole inhi­ bited the accumulation of (3-carotene and of an unidentified carotene. The biosynthesis of xanthophylls was similar to that in the control. Amitrole caused the ap...

Most methods for protein functional classification rely on the comparison of their amino acid sequence. However functional classification of proteins is strongly defined by their three dimensional structure. This approach is based on the fact that proteins from one fold keep the same structure even after evolutionary changes of their sequence. The underlying theme of the work is: ’can we find a...

We show that the hypercube has a face-unfolding that tiles space, and that unfolding has an edge-unfolding that tiles the plane. So the hypercube is a “dimension-descending tiler.” We also show that the hypercube cross unfolding made famous by Dali tiles space, but we leave open the question of whether or not it has an edge-unfolding that tiles the plane.

Interactive and multimedia methods are the future, already developing in teaching and learning modules in Medicine. It happens and has to happen because: 1) It improves tools for the teacher in preparing and showing the bulk of materials on which students must study and learn; it enables interactivity with learners both in formative pathway and in final assessment. 2) It improves attention, int...

The planning and design of future experiments rely heavily on forecasting to assess the potential scientific value provided by a hypothetical set measurements. Fisher information matrix, due its convenient properties low computational cost, provides an especially useful tool. However, matrix only reasonable approximation true likelihood when data are nearly Gaussian distributed observables have...
