Three-dimensional echocardiography (3DE) and speckle tracking echocardiography (STE) have recently applied as imaging techniques to accurately evaluate left atrial (LA) size, anatomy and function. 3DE and off-line quantification softwares, have allowed, in comparison to magnetic resonance imaging, the most time-efficient and accurate method of LA volume quantification. STE provides a non-Dopple...

allogeneic hematopoietic stem cell transplantation is used in the treatment of patients suffering from hematologic and non-hematologic disorders, but the application is limited by the identification of a suitable donor. umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell (hsc) transplantation. despite all advantages, the limited cell dose is one of the  major obstacle...

We present optimal embeddings of an n-node complete binary tree in a three-dimensional or a two-dimensional grid when k, the size of one of the dimensions of the grid, is given. For the three-dimensional case we show how to obtain, for any k in the range [1, n/2], a layout of O(n+k logn) volume. The same bound is shown to hold for the two-dimensional case when k is in the range [log n , n/2]. W...

The linearized treatment of the flow over a partially cavitating single hydrofoil having a flat pressure surface and a circular-arc suction side is presented. The flow is treated as a two-dimensional, steady, inviscid flow. Further assumptions made are those of incompressibility and irrotationality. The results obtained are compared with experiment and generally good correlation is found for th...

The results of our investigation of several measurements on digitized 2D and 3D objects with fuzzy borders are presented. The performance of surface area, volume, and roundness measure estimators for digitized balls with fuzzy borders is analyzed. The method we suggest provides significant improvement in precision, compared to analogous estimation results obtained on a crisp (hard) segmentation...
