La voce local dell'impresa: progetto, prodotto e territorio
No full textIl testo utilizza la riflessione sui motivi culturali che hanno portato alla creazione di un museo online dedicato al design toscano, MuDeTo, per documentare un percorso di ricerca progettuale legato alla particolarità di questo territorio, la cui storia e le cui produzioni hanno la stessa legittimità di quelle ben più note dell’area milanese. Sostenendo che non si può ritenere il design né atopico né apolide, il saggio illustra quell'insieme di saperi tecnici e artigianali, propri del luogo, che hanno promosso l'identità progettuale e produttiva della Toscana, presentando casi studio che documentano accanto all’impresa progettisti che ne hanno indirizzato la ricerca di innovazione con consapevolezza delle loro specificità tecniche e del loro mercato.The text starts from cultural reasons that led to the creation of an online museum dedicated to Tuscan design, MuDeTo, to document a project research path linked to the particularity of this territory, whose history and whose productions have the same legitimacy as those much more notes of the Milanese area. Arguing that design cannot be considered atopic or stateless, the essay illustrates that set of technical and artisan knowledge, typical of the place, which have promoted the design and production identity of Tuscany, presenting case studies that document alongside the company designers who have directed the search for innovation with awareness of their technical specificities and their market
Perceptual encoding (Tabachnick & Toscano, 2018)
No full textPurpose: A central question about auditory perception concerns how acoustic information is represented at different stages of processing. The auditory brainstem response (ABR) provides a potentially useful index of the earliest stages of this process. However, it is unclear how basic acoustic characteristics (e.g., differences in tones spanning a wide range of frequencies) are indexed by ABR components. This study addresses this by investigating how ABR amplitude and latency track stimulus frequency for tones ranging from 250 to 8000 Hz.Method: In a repeated-measures experimental design, listeners were presented with brief tones (250, 500, 1000, 2000, 4000, and 8000 Hz) in random order while electroencephalography was recorded. ABR latencies and amplitudes for Wave V (6–9 ms) and in the time window following the Wave V peak (labeled as Wave VI; 9–12 ms) were measured.Results: Wave V latency decreased with increasing frequency, replicating previous work. In addition, Waves V and VI amplitudes tracked differences in tone frequency, with a nonlinear response from 250 to 8000 Hz and a clear log-linear response to tones from 500 to 8000 Hz. Conclusions: Results demonstrate that the ABR provides a useful measure of early perceptual encoding for stimuli varying in frequency and that the tonotopic organization of the auditory system is preserved at this stage of processing for stimuli from 500 to 8000 Hz. Such a measure may serve as a useful clinical tool for evaluating a listener’s ability to encode specific frequencies in sounds.Supplemental Material S1.

Mini-invasive implant placement in combination with maxillary sinus membrane perforation during transcrestal sinus floor elevation: a retrospective study
No full textThe aim of this retrospective study was to report preliminary outcomes of a modified technique for transcrestal sinus floor elevation with simultaneous implant placement. A total of 165 implants were placed in 110 patients using a modified Summers technique. During implant site preparation, after fracturing the sinus floor, a small perforation of the membrane was made using the first osteotome. After grafting with anorganic bovine bone mixed with venous blood, standard-length implants were inserted. The prosthetic phase occurred after 4 to 5 months. Patients were followed for at least 2 years after loading. During the follow-up, sinus condition was assessed by cone beam computed tomography. Periapical radiographs were taken to assess graft height and peri-implant bone levels. Three implants failed within 2 months of placement, yielding an overall implant survival of 98.2%. The mean follow-up was 38.3 months (range: 28 to 60 months) from placement. All other implants were stable and peri-implant soft tissues were healthy throughout the observation period. Peri-implant bone loss averaged 0.62 ± 0.26 mm after 1 year of function. No biologic or biomechanical complications occurred. No evidence of graft material dispersion into the sinus space was detected, except for two cases that resolved spontaneously. After 1 year of loading the graft height averaged 4.8 ± 1.3 mm above the sinus floor level. In the presence of sinus membrane perforation, the proposed modified osteotome technique may allow a predictable rehabilitation of the atrophic posterior maxilla by means of standard length implants without the occurrence of adverse events

Dalla collaborazione dei due giapponesi sono nati cinque spettacoli che vedono la compresenza in scena di attori robot e attori carne ed ossa
A Genetic Algorithm for Three-Dimensional Discrete Tomography
Get PDFDiscrete tomography is a specific case of computerized tomography that deals with the reconstruction of objects made of a few density values on a discrete lattice of points (integer valued coordinates). In the general case of computerized tomography, several hundreds of projections are required to obtain a single high-resolution slice of the object; in the case of discrete tomography, projections of an object made by just one homogeneous material are sums along very few angles of the pixel values, which can be thought to be 0’s or 1’s without loss of generality. Genetic algorithms are global optimization techniques with an underlying random approach and, therefore, their convergence to a solution is provided in a probabilistic sense. We present here a genetic algorithm able to straightforwardly reconstruct binary objects in the three-dimensional space. To the best of our knowledge, our methodology is the first to require no model of the shape (e.g., periodicity, convexity or symmetry) to reconstruct. Experiments were carried out to test our new approach in terms of computational time and correctness of the solutions. Over the years, discrete tomography has been studied for many interesting applications to computer vision, non-destructive reverse engineering and industrial quality control, electron microscopy, X-rays crystallography, biplane angiography, data coding and compression
