The main purpose of this paper is to highlight the socializing value of motor activity, a factor often overlooked in the planning of the Italian school. To achieve this goal, we developed a research project that can rigorously demonstrate a…

This paper presents a multilayered architecture that enhances the capabilities of current QA systems and allows different types of complex questions or queries to be processed. The answers to these questions need to be gathered from factual information scattered throughout…

The eye is not a centered system. The line of sight connects the fovea with the center of the pupil and is usually tilted in the temporal direction. Thus, off-axis optical aberrations, mainly coma and oblique astigmatism, are introduced at…

The Millennium Development Goals (MDG) progress targets have not been met. Nevertheless, the United Nations (UN) has not yet undertaken in-depth review in order to discover the reasons behind this lack of progress in achieving the MDG. From a political…

A personal navigation system is proposed in the present paper. This system is based on the use of inertial sensors and will be a complement for the Global Positioning System in places where GPS signals are not available. Such places…

Kogelnik's coupled-wave (CW) theory has been used for decades to predict the diffraction efficiency of volume diffraction gratings. Although this theory has been applied with success to volume diffraction gratings recorded under a great variety of experimental conditions, its predictions…

The visual and optical anisotropies of metallic and pearlescent samples have been evaluated using a multi-gonio-spectrophotometer and by adapting a gonio-template over the instrument aperture for measuring the relative spectral reflectance factor when the sample is rotated around an axis…

15-Deoxy-Δ12,14-prostaglandin J2 (15dPGJ2) has been recently proposed as a potent anti-inflammatory agent. However, the mechanisms by which 15dPGJ2 mediates its therapeutic effects in vivo are unclear. We demonstrate that 15dPGJ2 at micromolar (2.5–10 µM) concentrations induces the expression of heme…

Real-time holographic interferometry has been used to visualize the evolution of the polarization layer during dead-end ultrafiltration of PEG-10000. Several experiments at a constant pressure of 1 bar and varying the feed concentration of PEG-10000 (5–12.5 kg/m3) have been carried…

Despite of the advances achieved in the past years in order to design more natural interfaces between intelligent systems and humans, there is still a great effort to be done. Considering a robot as an intelligent system, the determination of…
