OBJECTIVE To investigate whether the location and extent of the CT hyperdense artery sign (HAS) at presentation affects response to IV alteplase in the randomized controlled Third International Stroke Trial (IST-3). METHODS All prerandomization and follow-up (24-48 hours) CT brain scans in IST-3 were assessed for HAS presence, location, and extent by(More)
BACKGROUND Previous prognostic scoring systems in predicting stroke mortality are complex, require multiple measures that vary with time and failed to produce a simple scoring system. AIMS/HYPOTHESIS The study aims to derive and internally validate a stroke prognostic scoring system to predict early mortality and hospital length of stay. METHODS Data(More)
OBJECTIVES To examine the prognostic value of prestroke disability in predicting inpatient mortality and length of hospital stay (LOS) independent of age, sex, and stroke type and severity. DESIGN Retrospective analysis of prospectively collected stroke registers. SETTING United Kingdom. PARTICIPANTS Fourteen thousand four hundred thirty-seven(More)
The Internet has seen an increase in complexity due to the introduction of new types of networking devices and services, particularly at points of discontinuity known as network edges. As the networking industry continues to add revenue generating services at network edges, there is an increasing need to provide a systematic method for dynamically(More)
A significant challenge in today's Internet is the ability to efficiently incorporate customizable network intelligence in commercial high performance network devices. This paper tackles the challenge by introducing the Active Flow Manipulation (AFM) mechanism, a key enabling technology of the programmable networking platform Openet. AFM enhances the(More)
Introduction. The hyperdense internal carotid artery sign (HICAS) has been suggested as a common marker of terminal internal carotid artery (ICA) thrombus associated with poor outcomes following thrombolysis. We aimed to investigate the prevalence and prognostic significance of the HICAS in an unselected cohort of patients receiving intravenous(More)
Next generation applications and architectures (for example, Grids) are driving radical changes in the nature of traffic, service models, technology, and cost, creating opportunities for an advanced communications infrastructure to tackle next generation data services. To take advantage of these trends and opportunities, research communities are creating(More)
After a decade of research and development, IP multicast has still not been deployed widely in the global Internet due to many open technical issues: lack of admission control, poorly scaled with large number of groups, and requiring substantial infrastructure modifications. To provide the benefits of IP multicast without requiring direct router support or(More)
