This paper proposes a framework for segmenting di erent textured areas over synthetic or real textured frames by curves propagation. We assume that the system has the ability to be taught over di erent texture prototypes. For each prototype a global statistical model is generated, as a set of probability density functions attributes from a multi-valued frame analysis, where di erent lter respon...

This paper presents a novel variational method for image segmentation which is obtained by unifying boundary and region-based information sources under the Geodesic Active Region framework. A statistical analysis over the observed density function (image histogram) using a mixture of Gaussian elements, indicates the number of the di erent regions and their intensity properties. Then, the bounda...

This paper deals with a fundamental problem in motion and stereo analysis, namely that of determining the camera intrinsic calibration parameters. A novel method is proposed that follows the autocalibration paradigm, according to which calibration is achieved not with the aid of a calibration pattern but by observing a number of image features in a set of successive images. The proposed method ...

We have read with great interest the study by Khan et al.[1]: “Surgery for Tetralogy of Fallot in Adults: Early Outcomes”, published in the Brazilian Journal of Cardiovascular Surgery, volume 31, issue 4, pages 300-3. While the authors should be congratulated for their efforts to develop a pediatric cardiac surgery program in a difficult context, we have some comments, concerns, and questions a...

INTRODUCTION Stroke is a rapid loss of brain function due to disturbance blood flow to the brain. The existence of multiple risk factors, the length of their duration, and severity of each factor individually, is positively correlated with the occurrence of stroke. Stroke is the third cause of disability and premature death for men and women. AIM The aim of this research is that through clini...

Michael B. Sporn and Waun Ki Hong The spectacular clinical results reported by Meyskens, Gerner and colleagues in a lead article (1) of this very first issue of this new AACR journal on cancer prevention represent a landmark advance in efforts to stop the current worldwide epidemic of cancer deaths. This study also sets a new, exceptionally high standard for future clinical research on the chem...

The g-aminobutyric acid (GABA) receptor type B (GABABR) is constituted of at least two homologous proteins, GABABR1 and GABABR2. These proteins share sequence and structural similarity with metabotropic glutamate and Ca-sensing receptors, both of which are sensitive to Ca. Using rat brain membranes, we report here that the affinity of GABA and 3-aminopropylphosphinic acid for the GABABR recepto...
