Partitions which are simultaneously t1- and t2-core

Are TrueFISP images T2/T1-weighted?

Images acquired using the TrueFISP technique (true fast imaging with steady-state precession) are generally believed to exhibit T(2)/T(1)-weighting. In this study, it is demonstrated that with the widely used half-flip-angle preparation scheme, approaching the steady state requires a time length comparable to the scan time such that the transient-state response may dominate the TrueFISP image c...

25 Modeling and simulation of a network interface handling two priority levels. We propose a scheme called Double Queue Scheme to reduce the eeects of local jobs' communication on the performance of parallel jobs. It divides the only one input and output queues in traditional network interfaces into two ones. One is for the communication of parallel jobs, and the other is for the communication ...

Joint myocardial T1 and T2 mapping

Background Recent studies suggest that quantitative myocardial T1 mapping allows assessment of focal and diffuse fibrosis in the myocardium [1]. Quantitative T2 mapping has also been proposed to overcome challenges associated with T2 weighted imaging [2]. These maps are traditionally acquired with different sequences, necessitating image registration to evaluate them jointly. A sequence that ca...

Lattices on simplicial partitions which are not simply connected

In this paper, (d + 1)-pencil lattices on simplicial partitions in Rd, which are not simply connected, are studied. It is shown, how the fact that a partition is not simply connected can be used to increase the flexibility of a lattice. A local modification algorithm is developed also to deal with slight partition topology changes that may appear afterwards a lattice has already been constructed.
