Background In patients with prior myocardial infarction, intra-scar surviving fibers may create conducting channels (CC) which are the substrate of most sustained monomorphic ventricular tachycardias (VT). These channels can be identified by endocardial voltage mapping. Recent studies show high correlation between information from endocardial voltage mapping and delayed-enhanced MRI (DE-MRI) im...

Clinical computed tomography provides a single mineral density (MD) value for heterogeneous calcified tissues containing early and late stage pathologic formations. The novel aspect of this study is that, it extends current quantitative methods of mapping mineral density gradients to three dimensions, discretizes early and late mineralized stages, identifies elemental distribution in discretize...

A new approach for solving the fractal Euler-Bernoulli beam equation is proposed. The mapping of problems in non-differentiable fractals into corresponding continuum applying calculus (FdH3-CC) carried out. derived as a generalization using FdH3-CC under analogous assumptions ordinary and then it solved analytically. To validate spatial distribution self-similar response, three different classi...

Cell-centered and node-centered approaches have been compared for unstructured finite-volume discretization of inviscid fluxes. The grids range from regular grids to irregular grids, including mixed-element grids and grids with random perturbations of nodes. Accuracy, complexity, and convergence rates of defect-correction iterations are studied for eight nominally second-order accurate schemes:...

{ Cache Coherent Non-Uniform Memory Access (CC-NUMA) architectures have received strong interests from both academia and industries. This paper studies the performance impact of design choices at diierent levels of address and memory mapping on CC-NUMA architectures. Through execution-driven simulations of ve numerical programs, we nd close interactions between data allocation, global address t...

A new methodology named CALMANT (CC-cube Algorithms on Meshes and Tori) for mapping a kind of algorithms that we call CC-cube algorithm onto multicomputers with hypercube, mesh, or torus interconnection topology is proposed. This methodology is suitable when the initial problem can be expressed as a set of processes that communicate through a hypercube topology (a CC-cube algorithm). There are ...

introduction: sentinel node mapping has been used for laryngeal carcinoma in several studies, with excellent results thus far.in the current study, we report our preliminary results on sentinel node mapping in laryngeal carcinoma using intra-operative peri-tumoral injection of a radiotracer.   materials and methods: patients with biopsy-proven squamous cell carcinoma of the larynx were included...
