Improving food offer in order to prevent and tackle undernutrition
2021
When a person shows a decline in appetite or loses weight, is essential to adapt his/her diet in order to fulfil the nutritionc needs and prevent undernutrition. Three axes must but considered and combined: enriching diet (increasing the content of essential nutrients in a meal without increasing! the volume to be ingested); adapting food texture to orc capacities (chewing, salivation, swallowing); optimizing food sensory characteristics by taking into account food habit and food preferences.
Chirality selective spin interactions mediated by the moving superconducting condensate
2018
We show that superconducting correlations in the presence of nonzero condensate velocity can mediate the peculiar interaction between localized spins that breaks the global inversion symmetry of magnetic moments. The proposed interaction mechanism is capable of removing fundamental degeneracies between topologically distinct magnetic textures. For the generic system of three magnetic impurities in the current-carrying superconductor, we find the energy term proportional to spin chirality. In realistic superconductor/ferromagnetic/superconductor setups we reveal significant energy differences between various magnetic textures with opposite chiralities. We calculate Josephson energies of junc…

Automatic dynamic texture segmentation using local descriptors and optical flow
2012
A dynamic texture (DT) is an extension of the texture to the temporal domain. How to segment a DT is a challenging problem. In this paper, we address the problem of segmenting a DT into disjoint regions. A DT might be different from its spatial mode (i.e., appearance) and/or temporal mode (i.e., motion field). To this end, we develop a framework based on the appearance and motion modes. For the appearance mode, we use a new local spatial texture descriptor to describe the spatial mode of the DT; for the motion mode, we use the optical flow and the local temporal texture descriptor to represent the temporal variations of the DT. In addition, for the optical flow, we use the histogram of orie…

The Role of Textured Material in Supporting Perceptual-Motor Functions
2013
Simple deformation of the skin surface with textured materials can improve human perceptual-motor performance. The implications of these findings are inexpensive, adaptable and easily integrated clothing, equipment and tools for improving perceptual-motor functionality. However, some clarification is needed because mixed results have been reported in the literature, highlighting positive, absent and/or negative effects of added texture on measures of perceptual-motor performance. Therefore the aim of this study was to evaluate the efficacy of textured materials for enhancing perceptual-motor functionality. The systematic review uncovered two variables suitable for sub-group analysis within …
Diagnosis and prognosis of cardiovascular diseases by means of texture analysis in magnetic resonance imaging
2017
Cardiovascular diseases constitute the leading global cause of morbidity and mortality. Magnetic resonance imaging (MRI) has become the gold standard technique for the assessment of patients with myocardial infarction. However, limitations still exist thus new alternatives are open to investigation. Texture analysis is a technique that aims to quantify the texture of the images that are not always perceptible by the human eye. It has been successfully applied in medical imaging but applications to cardiac MRI (CMR) are still scarce. Therefore, the purpose of this thesis was to apply texture analysis in conventional CMR images for the assessment of patients with myocardial infarction, as an …
An evaluation of cool season turfgrassess in order to identify the species and varieties most suitable for the Mediterranean environment
2004
The cultivars of cool season Graminae species diffusely used to establish turfgrasses, are grown in northern areas of Europe. The aim of the research described in this paper was to identify the turfgrass species and cultivars most suitable for the Mediterranean environment. The trial was carried out in 1999 and 2000 at the experimental farm “Parco d’Orleans” belonging to the Department A.C.E.P. of University of Palermo. During the trial sixty different cultivars of cool season turf species were compared – 20 cultivars of Festuca arundinacea Schreb., 20 cultivars of Poa pratensis L., and 20 cultivars of Lulium perenne L. The main biometric and qualitative parameters examined were ground cove…
