OBJECTIVES The objective of this study was to compare electroanatomic mapping for the assessment of myocardial viability with nuclear metabolic imaging using positron emission computed tomography (PET) and with data on functional recovery after successful myocardial revascularization. BACKGROUND Animal experiments and first clinical studies suggested that electroanatomic endocardial mapping i...

BACKGROUND Despite the established role of late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) in characterizing chronic myocardial infarction (MI), a significant portion of chronic MI patients are contraindicative for the use of contrast agents. One promising alternative contrast free technique is diffusion weighted CMR (dwCMR), which has been shown ex vivo to be sensitiv...

BACKGROUND We investigated myocardial perfusion dynamics after thrombolysis and its clinical implications. METHODS AND RESULTS We studied 39 patients with acute anterior myocardial infarction (AMI). Myocardial contrast echocardiography (MCE) was performed before and immediately after successful reflow with intracoronary injection of sonicated Ioxaglate. The average segmental score by two-dime...

Two distinct strands of research are developed: new methodology for inference on the Markov modulated Poisson process (MMPP), and new theory on optimal scaling for the random walk Metropolis (RWM). A novel technique is presented for simulating from the exact distribution of a continuous time Markov chain over an interval given the start and end states and the infinitesimal generator. This is us...

It is widely known that topology, wireless range, and the movement patterns of devices often impose severe limitations on the ability of devices to communicate in Mobile Wireless Ad-hoc Networks (MANETs). However, there has been less research into the effect of devices’ movement speeds on network connectivity. In this paper we will look at two commonly used MANET movement patterns, Working Day ...

Here we present performance evaluation of different routing protocols such as SIFT, GPSR and GOSR using different mobility models like Fluid Traffic Model (FTM), Intelligent Driver Model and Random Waypoint Model (RWM) with Intersection Management (IDM-IM). We present simulation results that demonstrate the importance of choosing a mobility model in the simulation of a Vehicular Network Protoco...

The resistive wall mode ~RWM! poses a threat to many plasma confinement devices. The continuous rotation of the wall relative to the plasma makes it appear perfectly conducting, because of the skin effect, but this is ineffective if the perturbation locks to the wall. This raises the question of whether a nonuniformly rotating wall is more effective. In this paper we discuss the effect of such ...
