IMPORTANCE Time to thrombolysis is crucial for outcome in acute ischemic stroke. OBJECTIVE To determine if starting thrombolysis in a specialized ambulance reduces delays. DESIGN, SETTING, AND PARTICIPANTS In the Prehospital Acute Neurological Treatment and Optimization of Medical care in Stroke Study (PHANTOM-S), conducted in Berlin, Germany, we(More)
We relate two formerly independent areas: Formal concept analysis and logic of domains. We will establish a correspondene between contextual attribute logic on formal contexts resp. concept lattices and a clausal logic on coherent algebraic cpos. We show how to identify the notion of formal concept in the domain theoretic setting. In particular, we show(More)
IMPORTANCE The effectiveness of intravenous thrombolysis in acute ischemic stroke is time dependent. The effects are likely to be highest if the time from symptom onset to treatment is within 60 minutes, termed the golden hour. OBJECTIVE To determine the achievable rate of golden hour thrombolysis in prehospital care and its effect on outcome. DESIGN,(More)
With the evolution of linked open data sources, question answering regains importance as a way to make data accessible and ex-plorable to the public. The triple structure of RDF-data at the same time seems to predetermine question answering for being devised in its native subject-verb-object form. The devices of natural language, however , often exceed this(More)
Intrathecal immunoglobulin G (IgG) synthesis and oligoclonal IgG bands in cerebrospinal fluid (CSF) are hallmarks of multiple sclerosis (MS), but the antigen specificities remain enigmatic. Our study is the first investigating the autoantibody repertoire in paired serum and CSF samples from patients with relapsing-remitting MS (RRMS), primary progressive MS(More)
For a mobile robot to act autonomously, it must be able to construct a model of its interaction with the environment. Oates et al. developed an unsu-pervised learning method that produces clusters of robot experiences based on the dynamics of the interaction, rather than on static features. We present a semi-supervised extension of their technique that uses(More)
In acute ischemic stroke, time from symptom onset to intervention is a decisive prognostic factor. In order to reduce this time, prehospital thrombolysis at the emergency site would be preferable. However, apart from neurological expertise and laboratory investigations a computed tomography (CT) scan is necessary to exclude hemorrhagic stroke prior to(More)
