In reviewing this subject briefly, one finds that at the turn of the century, "infantile paralysis," as it was then called, was considered to be "rather rare after the age of six."' Indeed more than 50 per cent of the cases were under two years of age. In one of the earliest epidemics in the United States, occurring in Vermont in 1894, 90 out of the 120 cases whose ages were given were under th...

OBJECTIVES We propose an automatic breast mass detection algorithm in three-dimensional (3D) ultrasound (US) images using the Hough transform technique. METHODS One hundred twenty-five cropped images containing 68 benign and 60 malignant masses are acquired with clinical diagnosis by an experienced radiologist. The 3D US images are masked, subsampled, contrast-adjusted, and median-filtered as...

"Predecisional information distortion" occurs when decision makers evaluate new information in a way that is biased towards their leading option. The phenomenon is well established, as is the method typically used to measure it, termed "stepwise evolution of preference" (SEP). An inadequacy of this method has recently come to the fore: it measures distortion as the total advantage afforded a le...

Value sets for the EQ-5D-5L are required to facilitate its use in estimating quality-adjusted life years. An international protocol has been developed to guide the collection of stated preference data for this purpose and has been used to generate EQ-5D-5L valuation data for England. The aim of this paper is report the innovative methods used for modelling those data to obtain a value set. Nine...

Ground beef has been implicated as a transmission vehicle in foodborne outbreaks of infection with pathogens such as Escherichia coli O157:H7 and Salmonella. During outbreak investigations, traceback of contaminated beef to the producing facility is often unsuccessful because of inadequate recordkeeping at retail establishments that grind beef products. We conducted a survey in three states par...

This paper attempts to stand back and consider how the field o f software dependability research has progressed over the last twenty-five or so years. It provides a personal perspective on early developments such as the recovery block and the Nversion programming scheme, and on more recent research in which the author has been involved aimed at unifying and extending these schemes. It then disc...

Architecture is part of everyone’s daily life, we live in buildings, and our life is an ongoing transit between open and enclosed spaces. One of the main attractions for a tourist is definitely architecture. Architecture, urbanism and tourism involve several players. Among them are travel agencies and organizations that promote specialized trips. Arquexplora is the result of my background as an...

INTRODUCTION Improving social inclusion opportunities for population health has been identified as a priority area for international policy. There is a need to comprehensively examine and evaluate the quality of psychometric properties of measures of social inclusion that are used to guide social policy and outcomes. OBJECTIVE To conduct a systematic review of the literature on all current me...

Numerous functional magnetic resonance imaging (fMRI) studies have identified multiple cortical regions that are involved in face processing in the human brain. However, few studies have characterized the face-processing network as a functioning whole. In this study, we used fMRI to identify face-selective regions in the entire brain and then explore the hierarchical structure of the face-proce...
