OBJECTIVE First, to determine the sensitivity and specificity of six stroke recognition scores in a single cohort to improve interscore comparability. Second, to test four stroke severity scores repurposed to recognise stroke in parallel. METHODS Of 9154 emergency runs, 689 consecutive cases of preclinically 'suspected central nervous system disorder'(More)
We studied the competition between heterogeneous and homogeneous nucleation of an aqueous suspension of charged colloidal spheres close to the container walls. Samples of equilibrium crystalline structure were shear-melted and the metastable melt left to solidify after the cessation of shear. The crystallization kinetics was monitored using time-resolved(More)
OBJECTIVE To develop an NIH Stroke Scale (NIHSS)-compatible, all-in-one scale for rapid and comprehensive prehospital stroke assessment including stroke recognition, severity grading and progression monitoring as well as prediction of large vessel occlusion (LVO). METHODS Emergency medical services (EMS) personnel and stroke physicians (n=326) rated each(More)
Congestion in wireless sensor network (WSN) is one of the critical problems still from its evolution. Congestion in WSN can be a severe problem, as it causes plethora of malfunctions such as packet loss, lower throughput, energy efficiency, increase in collisions, increase in queuing delay and decreased network lifetime. As a result, the performance of the(More)
