This work proposes a pixel-classification approach for vessel segmentation in X-ray angiograms. The proposal uses textural features such as anisotropic diffusion, features based on the Hessian matrix, mathematical morphology and several others. These

The temperature dependence of the vibrational modes of lead barium niobate (PbxBa1–xNb2O6), which belongs to the tungsten-bronze family of oxygen octahedra ferroelectrics, were investigated for the first time using the Raman scattering technique. T

Lead zinc niobate–lead titanate[(1−x)Pb(Zn1/3Nb2/3)O3–xPbTiO3] (PZN–PT) crystals with x=4.5% and x=12% have been investigated using dielectric and Raman measurements over a range of temperatures. Above room temperature, dielectric measurement

The necessity to produce materials with better performances than those observed in ferroelectric perovskites has generated the creation of new oxides, especially those belonging to the Aurivillius family. In the last few years much attention has been

We determined the effect of long-term exposure to beta-agonists on beta(1)-adrenergic receptors (beta(1)-AR) in human neuroepithelioma SK-N-MC cells because earlier studies have indicated that beta(1)-AR in this cell line are resistant to agonist-ind

We investigated the effect of endotoxemia on alpha1-adrenergic receptor-mediated smooth muscle contraction as measured by mean arterial pressure (MAP) in response to incremental doses of a vasopressor. Twelve male Sprague-Dawley rats were randomized
