Saliency Based Image Cropping

2013

Image cropping is a technique that is used to select the most relevant areas of an image, discarding the useless ones. Handmade selection, especially in case of large photo collections, is a time consuming task. Automatic image cropping techniques may help users, suggesting to them which part of the image is the most relevant, according to specific criteria. We suppose that the most visually salient areas of a photo are also the most relevant ones to the users. In this paper we present an extended version of our previously proposed method, to extract the saliency map of an image, which is based on the analysis of the distribution of the interest points of the image. Three different interest…

La selezione dei giudici della Corte di giustizia dell'Unione. Nuove prospettive di integrazione e legittimazione.

2014

Abstract The appointment of judges to supranational and international courts has long been a neglected area of sovereign activity. However, the growing role and significance of the European Court of Justice (ECJ), by now one of the most significant players within the European political and constitutional space, demands reforms which also affect its architecture. The creation of the advisory panel under article 255 TFUE, whose task is to provide the Council with opinions on candidates suitability, it could be considered one of the most interesting novelties introduced by the Lisbon Treaty. Indeed, the panel is definitely a way to improve judicial independence and proficiency but also a means…

Il dibattito sul canone delle donne e le sue ricadute. Qualche annotazione

2023

Questo breve contributo torna a riflettere intorno al dibattito sul canone letterario italiano e la scrittura delle donne degli ultimi trent’anni: un fecondo conflitto delle idee che consente ormai di ripensare modi e criteri di selezione e trasmissione dei testi letterari italiani.

A decomposition of Denjoy-Khintchine-Pettis and Henstock-Kurzweil-Pettis integrable multifunctions

2010

We proved in one of our earlier papers that in case of separable Banach space valued multifunctions each Henstock-Kurzweil-Pettis integrable multifunction can be represented as a sum of one of its Henstock-Kurzweil-Pettis integrable selector and a Pettis integrable multifunction. Now, we prove that the same result can be achieved in case of an arbitrary Banach space. Moreover we show that an analogous result holds true also for the Denjoy-Khintchine-Pettis integrable multifunctions. Applying the representation theorem we describe the multipliers of HKP and DKP integrable functions. Then we use this description to obtain an operator characterization of HKP and DKP integrability.

Diagnostic techniques and multidisciplinary approach in idiopathic granulomatous mastitis: A revision of the literature

2019

Idiopathic granulomatous mastitis (IGM) is a chronic benign inflammatory disease of the breast that may mimic breast cancer. It is most common in parous young fertile women, although it can occur in nulliparous women and in men. IGM is an idiopathic disease due to the influence of some environmental factors in genetically predisposed subjects. Several pathogenic hypothesis have been proposed in the last years (autoimmune, hormonal, infective genesis). IGM presents as a painful palpable mass located in one of the two udders. The skin is usually normal but could present signs of inflammation with or without lymph nodes involvement. Ultrasonography, mammography, magnetic resonance can be diagn…

Selenium and Autoimmune Thyroiditis

2019

The essential mineral, selenium, is of fundamental importance to human health. As a constituent of selenoproteins, selenium has structural and enzymic roles, in the latter context being best-known as an antioxidant and catalyst for the production of active thyroid hormone. Selenium is needed for the proper functioning of the immune system. An elevated selenium intake may be associated with reduced cancer risk

SELENIUM AND AUTOIMMUNE THYROIDITIS

2023

Selenium (Se) is an essential trace element of pivotal importance to human health. Se is incorporated into selenoproteins (SePs) which have pleiotropic effects, including antioxidant and anti-inflammatory effects, and in the production of active thyroid hormone. These findings may explain the relationship between Se deficiency and pathogenesis of various human diseases including thyroid disorder. In line with these observations, the therapeutic effectiveness of Se supplementation has already been reported in patients with various thyroid diseases. However, there are still controversial data about the optimal dose of Se to be administered, as well as the duration and efficacy of treatment an…

Using differential geometric LARS algorithm to study the expression profile of a sample of patients with latex-fruit syndrome

2011

Natural rubber latex IgE-mediated hypersensitivity is one of the most important health problems in allergy during recent years. The prevalence of individuals allergic to latex shows an associated hypersensitivity to some plant-derived foods, especially freshly consumed fruit. This association of latex allergy and allergy to plant-derived foods is called latex-fruit syndrome. The aim of this study is to use the differential geometric generalization of the LARS algorithm to identify candidate genes that may be associated with the pathogenesis of allergy to latex or vegetable.

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Distance Measures for Portfolio Selection

2017

The classical Markowitz approach to the portfolio selection problem (PSP) consists of selecting the portfolio that minimises the return variance for a given level of expected return. By solving the problem for different values of this expected return we obtain the Pareto efficient frontier, which is composed of non-dominated portfolios. The final user has to discriminate amongst these points by resorting to an external criterion in order to decide which portfolio to invest in. We propose to define an external portfolio that corresponds to a desired criterion, and to assess its distance from the Markowitz frontier in market allowing for short-sellings or not. We show that this distance is ab…
