Re-assessing the “Classify and Count” Quantification Method

An Attempt to re-classify the Rotifers

FIVE-AND-FORTY years have elapsed since Ehrenberg published his classification of the Rotifera, and his system still holds its ground. The mere statement of the fact is high praise; for what have not classifiers altered, and attempted to alter, during the last half century ? Not that his classification has escaped challenge. It was sharply criticised in the ' Histoire naturelle des Zoophytes*by...

The simplest method to classify CAM lesions

CAM lesions are now seen as a significant pathology that could cause osteoarthritis of the hip joint. Currently there is no gold standard for classifying these lesions. We aim to show a simple method for classifying these lesions based on shape and position. Using CT 3D reconstruction, 91 preoperative CT scans from patients who had undergone hip arthroscopy for femoroacetabular impingement, wer...

Satellite Re-entry Modeling and Uncertainty Quantification

LEO trajectory modeling is a fundamental aerospace capability and has applications in many areas of aerospace, such as maneuver planning, sensor scheduling, re-entry prediction, collision avoidance, risk analysis, and formation flying. Somewhat surprisingly, modeling the trajectory of an object in low Earth orbit is still a challenging task. This is primarily due to the large uncertainty in the...

The role of oral dipyridamole stress gated SPECT in assessing the response of the left ventricle to stress: Re-evaluation of an old method

Introduction: We aimed to assess whether the vasodilator effect of oral dipyridamole on the left ventricular systolic function in patients with suspected CAD is different from that of intravenous (IV) dipyridamole using Tc-99m MIBI myocardial perfusion gated SPECT. Methods: Eighty-nine patients (17 M / 72 W; 61 ± 10 years) were enrolled in this study. The patients underwent a dipyridamole stre...
