Presentations of Morse homology for studying shape of manifolds
No full textA new paradigm for describing the shape of manifolds is presented,with a particular regard to applications in pattern recognition.Given a Morse function f defined on a closed smooth manifoldM, the shape of the pair (M,f) is represented by the evolutionof the homology groups of the lower level sets of M with respect to f. The main tool is classical Morse theory. Analgorithm for treating the case of orientable surfaces is given
Low-level laser therapy and vibration therapy for the treatment of localized adiposity and fibrous cellulite
No full textIntroduction: In recent years, there has been an upsurge in the application of low-level laser therapy in various medical diseases. Additionally, vibration therapy is a new and effective measure to prevent muscular atrophy and osteoporosis, along with some general health-related beneficial effects of exercise on skeletal muscles such as improvement of endothelial function and an increased enzyme capacity of energy metabolism. The aim of this study was to evaluate the application of a 635 nm and 0.040W exit power per multiple diode laser in combination with vibration therapy for the application of non-invasive reduction of circumference in patients with localized adiposity and cellulite. Methods: The study enrolled men and women (N = 33) aged 18-64 years with localized adiposity or fibrous cellulite. The evaluation parameters were: photographic evaluation, perimetric evaluation, blood tests, ecographic evaluation, histological evaluation, and subjective and objective tests. Results: The results produced were statistically analyzed and resulted in a significant reduction of fat thickness when compared to the measurement prior to the treatment (P<0.0001). Moreover, subjective and objective tests, as well as ecographic and histological evaluations, confirmed the reduction of fat thickness. Conclusion: In this study we have demonstrated the safety and efficacy of the combination between low-level laser therapy and vibration therapy for the resolution of localized adiposity and fibrous cellulite. © The Author(s) 2013
A variational approach to Gibbs artifacts removal in MRI
No full textGibbs ringing is a feature of MR images caused by the finite sampling of the acquisition space (k-space). It manifests itself with ringing patterns around sharp edges which become increasingly significant for low-resolution acquisitions. In this paper, we model the Gibbs artefact removal as a constrained variational problem where the data discrepancy, represented in denoising and convolutive form, is balanced to sparsity-promoting regularization functions such as Total Variation, Total Generalized Variation and L1 norm of the Wavelet transform. The efficacy of such models is evaluated by running a set of numerical experiments both on synthetic data and real acquisitions of brain images. The Total Generalized Variation penalty coupled with the convolutive data discrepancy term yields, in general, the best results both on synthetic and real data
Brain stem acoustic evoked potentials recorded from the human mesencephalon
No full textNear field brain stem evoked potentials (NF-BAEPs) were recorded by means of an intraparenchymatous electrode placed in the right mesencephalon, during a stereotactic-guided biopsy of a tumor. The traces were compared with far field BAEPs (FF-BAEPs) obtained intraoperatively with scalp electrodes. The findings suggest a peripheral origin of wave II, a bilateral source of wave III and a main contralateral source of wave IV, while wave V seems to take origin mainly from the homolateral upper brain stem. Some intraparenchymatous activities do not project to the scalp. The possible impairments of NF-BAEP due to the presence of the tumor and the challenges of unidimensional single electrode recording are discussed
Reciprocal root locus approach to path planning for multiple mobile robots
No full textThe path planning problem for multiple mobile robots is addressed in this study. Given the available mobile robots and the tasks to be executed, at the highest planning level a first problem is the assignment of tasks to robot or AGV, the second is path planning. In this case a quickplanning is desirable for computing feasible paths in a given workspace without congestion. The proposed solution is based on the theory of conformal transformations that can be used to map the given workspace in a more appealing geometric setting. Some examples are considered to illustrate the proposed technique and its efficienc
