The new approach to the P-wave arrival time determination based on acoustic emission data from loading experiments is tested. The algorithm used in this paper is built on the STA/LTA function computed by a convolution that speeds up the computation process very much. The picking process makes use of shifting of temporary onset until certain conditions are fulfill and as a main decision criterio...

BACKGROUND AND PURPOSE Neuroimaging techniques such as diffusion- and perfusion-weighted MR imaging have been proposed as tools for advanced diagnosis in hyperacute ischemic stroke. There is, however, substantial doubt regarding the feasibility and practicality of applying MR imaging for the diagnosis of stroke on a routine basis, especially with respect to possible delay for specific treatment...

BACKGROUND Intravenous thrombolysis is an approved treatment method for patients with acute ischemic stroke (AIS) and is recommended by multiple guidelines. However, it seems that it is less frequently used in the developing countries compared to the developed countries. OBJECTIVES The purpose of this study was to estimate the percentage of patients with AIS, eligible for intravenous thrombol...

We compute in a relativistic way the time-of-arrival and the traversal time through a region of a free particle with spin 1 2 . We do this by applying the relativistic extension of the Event-Enhanced Quantum Theory which we have presented in a previous paper. We find a very good coincidence of the results of our formalism and the results obtained by using classical relativistic mechanics. PACS ...

conclusions the delay time from symptom onset to hospital admission was high in patients with ami. it is necessary to create emergency medical system (ems) stations in suburbs and train the public on the importance of quick contact with the ems when the symptoms of an ami are observed. results the median delay was 129 minutes (mean ± sd, 240.44 ± 295.30). overall, 32.5% of patients were admitte...

BACKGROUND AND PURPOSE Although the National Institutes of Neurological Disorders and Stroke (NINDS) has established time targets for the evaluation of acute stroke patients, little is known about how often these targets are met in the community. To track compliance with NINDS guidelines, Cuyahoga County Operation Stroke implemented a countywide data collection process that provides comparative...
