Youth- and parent-rated screening measures derived from the Strengths and Difficulties Questionnaire (SDQ) and Development and Well-Being Assessment (DAWBA) were compared on their psychometric properties as predictors of caseness in adolescence (mean age 14). Successful screening was judged firstly against the likelihood of having an ICD-10 psychiatric diagnosis and secondly by the ability to d...

In this issue of iJACC (JACC: Cardiovascular Imaging), Botvinick et al. (1) perform a complex study involving the performance of equilibrium radionuclide myocardiography with phase analysis during ventricular tachycardia. The authors identify specific characteristics that define tolerability of the arrhythmia in individual patients. Most of these discriminating factors in the 2 patient groups i...

As we move, the projection of moving objects on our retinas generates an array of velocity vectors known as optic flow. One class of optic flow is spiral motion, defined by the angle between a local vector direction and the direction of the steepest increase in local speed. By discriminating among such angles, an organism could discern between different flow patterns and effectively interact wi...

Regular monitoring of benzimidazole resistance status helps in timely implementation of resistance mitigation strategies in farms. Egg hatch assay (EHA) evaluates the ability of benzimidazoles to inhibit or prevent embryonation and hatching of nematode eggs and is the standard in vitro test for detection of benzimidazole resistance. The present study reports detection of benzimidazole resistanc...

The purpose of the present study was to investigate and compare the segmentation ability of the Gaussian Mixture Models (GMM) against the Seeded Region Growing (SRG) methods in microarray spots segmentation. A simulated microarray image, each containing 200 spots, was produced. An automatic gridding process was developed in MATLAB and it was applied on the images for identifying the centers of ...

Data are reported from 3,213 research eyewitnesses confirming that accurate eyewitness identifications from lineups are made faster than are inaccurate identifications. However, consistent with predictions from the recognition and search literatures, the authors did not find support for the "10-12-s rule" in which lineup identifications faster than 10-12 s maximally discriminate between accurat...

A difficult result to interpret in Computerized Adaptive Tests (CATs) occurs when an ability estimate initially drops and then ascends continuously until the test ends, suggesting that the true ability may be higher than implied by the final estimate. We explain why this asymmetry occurs and show that early mistakes by high ability students can lead to considerable underestimation, even in test...

This paper proposes a novel offline signature verification scheme. The idea behind the extraction of stroke speed is to extract dynamic feature from a static signature. In order to obtain the speed of the stroke, the intensity of the stroke is considered. This is because intensity is directly proportional to speed of the stroke. Faster the stroke speed, higher is its intensity value. Several ex...

We adapt the alias type technology to deal with primitives supporting environmentawareness (that is, the ability to adapt the behavior of according to the capabilities of the environment). In particular, we propose a type and effect system for an imperative object-based calculus with a primitive for discriminating the presence or absence of object’s attributes. Both the shape of environments wh...
