Introduction Patients with thyroid cancer in different age groups present with different prognosis. Objective The objective of this study is to analyze the clinicopathological pattern of thyroid carcinoma presentation according to age groups. Methods This is a retrospective study. From 2000 to 2010, 623 patients underwent thyroidectomy for cancer in our institution, with 596 enrolled. Patients ...

OBJECTIVE To evaluate how pulmonologists view the impact that asthma and COPD has on their patients, as well as how they treat these diseases. METHODS Survey including 227 pulmonologists participating in the VI Brazilian Asthma Conference, II Brazilian COPD Conference and II Brazilian Smoking Conference, all of which were held in 2007. RESULTS According to the answers given by the pulmonolo...

BACKGROUND Data are lacking on the proportion of physicians who face malpractice claims in a year, the size of those claims, and the cumulative career malpractice risk according to specialty. METHODS We analyzed malpractice data from 1991 through 2005 for all physicians who were covered by a large professional liability insurer with a nationwide client base (40,916 physicians and 233,738 phys...

In this paper we propose, and analyze from the computational complexity point of view, a new variant of nondeterministic Turing machines. Such a machine accepts a given input word if and only if one of its shortest possible computations on that word is accepting; on the other hand, the machine rejects the input word when all the shortest computations performed by the machine on that word are re...

Issues in sentence categorization according to language is fundamental for NLP, especially in document processing. In fact, with the growing amount of multilingual text corpus data becoming available, sentence categorization, leading to multilingual text structure, opens a wide range of applications in multilingual text analysis such as information retrieval or preprocess-ing of multilingual sy...

Surveillance technologies are used all over the world for various reasons. In urban environments, surveillance technologies are predominantly used for detecting or preventing crimes. Simultaneously, an increasing number of technologies are used for medical monitoring at home, but also at clinical facilities, and at public environments for assuring patients’ medical safety. An intensive policy d...

Suppose you have just acquired a number of articles into a personal digital library. The classification procedures described here would allow those articles to be automatically sorted in your pre-existing desktop folders. We use the Chi-square statistic to find keywords that we use to classify the articles, and the Support Vector Classifier to organize the articles in folders. Moreover we have ...

The Exact Geometric Computation (EGC) mode of computation has been developed over the last decade in response to the widespread problem of numerical non-robustness in geometric algorithms. Its technology has been encoded in libraries such as LEDA, CGAL and Core Library. The key feature of EGC is the necessity to decide zero in its computation. This paper addresses the problem of providing a fou...

This paper 1 deals with the normal density of n dependent random variables. This is a function of the form : ce ?x T Ax where A is an n n positive deenite matrix, x is the n?vector of the random variables and c is a suitable constant. The rst problem we consider is the (approximate) evaluation of the integral of this function over the positive orthant Z 1 x1=0 Z 1 x2=0 ... Z 1 xn=0 ce ?x T Ax :...

Current document retrieval tools succeed in locating large numbers of documents relevant to a given query. While search results may be relevant according to the topic of the documents, it is more difficult to identify which of the relevant documents are most suitable for a particular user. Automatic genre analysis that is, the ability to distinguish documents according to style would be a usefu...
