This study evaluated six segmentation methods (clustering, flood-fill, graph-cut, colour-thresholding, watershed, and Otsu’s-thresholding) for accuracy classification in discriminating Fusarium infected corn grains using RGB colour images. The was calculated Jaccard similarity index Dice coefficient comparison with the gold standard (manual method). Flood-fill graph-cut showed highest of 77% 87...

The segmentation of macroscopically ill-defined and highly variable structures, such as the hippocampus Hc and the amygdala Am, from MRI requires specific constraints. Here, we describe and evaluate a hybrid segmentation method that uses knowledge derived from a probabilistic atlas and from anatomical landmarks based on stable anatomical characteristics of the structures. Combined in a previous...

The bacteriologic and clinical efficacies of 3 days of lomefloxacin therapy were compared with those of 3 days of norfloxacin therapy for the treatment of acute uncomplicated urinary tract infections in a prospective, randomized, double-blind study. One hundred sixty-four subjects were enrolled at five Canadian centers; 84 received lomefloxacin, and 80 received norfloxacin. Escherichia coli (84...

In this paper we consider the one-dimensional compaction prob· lem when the layout area contains forbidden regions and the layout components are allowed to move across these regions. Given n layout components and k forbidden regions, each of rectangular shape, we show how to solve this compaction problem in O(A) time with O(Cn + k) log k + 0 logo) preprocessing, where 6. and 6 are measures for ...

In this paper we consider the I-dimensional compaction problem when the layout area contains forbidden regions and the layout components are allowed to move across these regions. Assume we are given a feasible layout containing k forbidden regions and n layout components, where the i-th layout component is a rectilinear polygon consisting of Vi vertical edges, v = L~l Vi· We present an algorith...

Ektaphelenchoides fuchsi n. sp., recovered from a soil sample around the rhizosphere of Cucurbita maxima in western Iran, is described and illustrated based on morphological and molecular characters. The new species is characterized by its body length of 529-712 µm, continuous lip region, lateral fields with three incisures, total stylet length of 14-18 µm with rounded basal knobs, excretory po...

BACKGROUND We evaluated the effect of coadministration of β-blocker (carvedilol) as the third agent with angiotensin II receptor blockers (ARB) and calcium channel blockers (CCB) on blood pressure (BP) regulation and glucose metabolism. METHODS Diabetic patients who did not achieve the therapeutic BP goal (140/90 mmHg) by ARB and CCB combination therapy were recruited. This study was designed...
