Experiments with an adaptive Bayesian restoration method
No full textThis paper describes a Bayesian restoration method applied to two-dimensional measured images, whose detector response function is not completely known. The response function is assumed Gaussian with standard deviation depending on the estimate of the local density of the image. The convex hull of the K-nearest neighbours (KNN) of each 'on' pixel is used to compute the local density. The method has been tested on 'sparse' images, with and without noise background. © 1989

Get PDFCan spa rehabilitative interventions play a role for patients suffering from neurodegenerative disorders at the early stages? A scoping review
Get PDFThe global burden of neurodegenerative disorders is significantly increasing as life expectancy rises but currently there is no cure for these conditions. An extensive search on MEDLINE (PubMed) and PEDro databases was conducted selecting clinical trials, Randomized Controlled Trials, and longitudinal studies published in the last 20 years in order to highlight what evidence there is for a role of spa rehabilitative interventions for patients with neurodegenerative diseases, in terms of motor function, symptoms, and quality of life (QoL) improvement and cost-effectiveness. A total of 225 publications were analyzed. Only three manuscripts were selected for review because they matched the inclusion criteria. These studies demonstrated statistically significant differences in the outcomes evaluated among patients affected by Parkinson’s disease after thermal rehabilitative treatments: motor function, balance, QoL, and psychological well-being statistically improved. In addition, rehabilitation in the spa setting seemed to be cost-effective for these patients. However, further studies are needed to define the role of spa rehabilitative interventions for these patients as the literature is still limited
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
PDB: A pictorial database oriented to data analysis
No full textThe paper describes a new pictorial database oriented to image analysis, implemented inside the MIDAS data analysis system. Pictorial databases need expressive data structures in order to represent a wide class of information from the numerical to the visual. The model of the database is relational; however, a full normalization is not achievable, owing to the complexity of the visual information. The paper reports the general design and notes on the software implementation. Preliminary experiments show the performance of the pictorial database. Copyright © 1993 John Wiley & Sons, Lt
Post COVID-19 persistent fatigue: a proposal for rehabilitative interventions in the spa setting
Get PDFWith this letter to Editor, we aim at offering our viewpoint on the potential use of the spa resources to contribute to the treatment of persistent COVID-19 sequelae. In particular, our argumentations focus on the comprehensive management of fatigue persisting after the resolution of the acute infection. This sequela seems to be the most frequent disabling outcome, leading to a delay in social reintegration and return to working life. We suggest that spa facilities including multidisciplinary interventions and trained staffs could be an appropriate setting for providing rehabilitative protocols to treat chronic fatigue in post COVID-19 subjects. Spa treatments may improve the physical symptoms of chronic fatigue and modulate the immune imbalance, reducing persisting inflammation. Moreover, in the spa setting, specific respiratory rehabilitation and neuropsychological interventions could be provided. The rehabilitative protocol could also properly address comorbidities. In conclusion, respecting the hygiene and preventive measures, the spa setting could represent the appropriate environment to take care of post-COVID chronic fatigue, offering adequate and multidisciplinary rehabilitation protocols. Further, prospective trials on this topic are needed to fully evaluate the positive impact of a comprehensive rehabilitative treatment in the spa environment for subjects with post-COVID-19 fatigue
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
An Italian study on psoriasis and depression
No full textBackground: Psoriasis is often associated with the risk of physical disability, social discomfort and psychological disorders. Objectives: The aim of this study was to investigate the prevalence of depressive symptomatology among Italian patients with psoriasis vulgaris, in order to better evaluate the disease severity in this patient population. Methods: Five thousand Italian patients with psoriasis were mailed the Center for Epidemiological Studies-Depression Scale (CES-D) questionnaire, a 20-item instrument developed to perform epidemiological studies of depressive symptomatology in the general population. Questionnaires with responses to 16 or more items were considered evaluable. Results: We received evaluable questionnaires from 2,391 patients, including 1,528 men (63.9%) and 863 women (36.1%). Depressive symptomatology was observed in 1,482/2,391 patients (62% overall; females, 63%; males, 61%). Men = 40 years of age (67 vs. 58%, respectively; p = 0.002). Depressive symptomatology was more prevalent in psoriatic patients with only primary or secondary education than in psoriatic patients with higher education (51 vs. 32%, respectively; p < 0.02). Conclusion: Our results are consistent with previous studies showing that psoriasis is associated with profound psychological morbidity, in particular with depression in a large number of patients. It is important to consider this association in the overall management of psoriasis
