OBJECTIVE To assess the outcome on management recommendations of a comparative approach vs a morphologic approach in evaluating dermoscopic images of lesions from a series of patients with multiple nevi. DESIGN In a 2-step study, 6 experienced dermoscopists were asked to provide management recommendations (excision or follow-up) for a series of lesions from patients with multiple nevi based o...

Comparison is widely used by consumers during the process of product evaluation in order to emphasize their preference, which can contribute to a proxy for product competitiveness analysis. This paper proposes a novel method for mining comparative sentences based on the achievements of linguistic study. The definition of comparative sentence subcategory is put forward and a mixed rule pool cont...

BACKGROUND AND AIM OF STUDY Pressure gradients across cardiac valve prostheses have been identified as one of the most important performance measures in valve replacement surgery. Specifically in aortic valves, these gradients influence reduction of left ventricular hypertrophy and are postulated to influence long-term survival. The correct choice of replacement valve is hampered by a lack of u...

Preliminaries and

Ten hospitalized patients performed two exercise tests per day on five consecutive days to determine the efficacy and duration of action of three sublingual long-acting nitrate preparations: isosorbide dinitrate, pentaerythritol trinitrate, and erythrityl tetranitrate. The duration of exercise to the point of ischemia, manifest as typical anginal pain and/or 1.0 mm ST-segment depression, was de...

Implicit authentication (IA) schemes use behavioural biometrics to continuously and transparently authenticate mobile device users. Several IA schemes have been proposed by researchers which employ different behavioural features and provide reasonable detection accuracy. While these schemes work in principle, it is difficult to comprehend from these individual efforts which schemes work best (i...

Ad hoc Network is a temporary network and these networks nodes are free to move about and organize themselves into a network. These nodes change position frequently. A Reactive (on-demand) routing strategy is a popular routing category for wireless ad hoc routing. The design follows the idea that each node tries to reduce routing overhead by sending routing packets whenever a communication is r...

In this paper we present a comparative evaluation of four popular interactive segmentation algorithms. The evaluation was carried out as a series of user-experiments, in which participants were tasked with extracting one hundred objects from a common dataset: twenty-five with each algorithm, constrained within a time limit of two minutes for each object. To facilitate the experiments, a “scribb...
