conclusions small dose of clopidogrel (75 mg) may lead to rare, life-threatening dah, so physicians should be aware of the possibility of dah after neurointervention in patients who have respiratory distress, worsening alveolar infiltrates accompanied by hemoptysis. introduction diffuse alveolar hemorrhage (dah) is a very rare complication but acute and life-threatening event. clopidogrel has g...

interventional techniques aim to find safer and better ways to treat vascular diseases even in many instances, the interventional radiology solutions has been considered the only treatment option for the patients. interventional radiologists are specialists who perform minimally invasive procedures instead of surgery or other treatments. these procedures apply various imaging and catheterizatio...

This application note describes the procedure for adjusting the brightness of light emitting diodes (LEDs) in applications by means of resistors. For better repeatability, the calculation of the required resistance values is shown by means of an example.

We present a new approach for Cluster Analysis based on a Greedy Randomized Adaptive Search Procedure (GRASP), with the objective of overcoming the convergence to a local solution. It uses a probabilistic greedy Kaufman initialization to get initial solutions and K-Means as a local search algorithm. The approach is a new initialization one for K-Means. Hence, we compare it with some typical ini...

Task-switching procedures provides a means to study the interplay between goal-directedness and cognitive flexibility at a fine temporal grain. Most such procedures cue the current task perceptually on all trials, which means that processes related to this cue factor into behavioral measures on all trials. The extended-runs procedure discussed here makes it possible to isolate stimulus-related ...

A random sample of size N is divided into k clusters that minimize the within cluster sum of squares locally. This k-means clustering method can be used as a quick procedure for constructing variable-cell historgrams that have no empty cell. A histogram estimate is proposed in this paper, and is shown to be uniformly consistent in probability.
