The ALPS Collaboration runs a “light shining through a wall” (LSW) experiment to search for photon oscillations into “weakly interacting sub-eV particles” (WISPs) inside of a superconducting HERA ...dipole magnet at the site of DESY. In this paper we report on the first successful integration of a large-scale optical resonant cavity to boost the available power for WISP production in this type of experiments. The key elements are a frequency tunable narrow line-width continuous wave laser acting as the primary light source and an electronic feed-back control loop to stabilize the power build-up. We describe and characterize our apparatus and demonstrate the data analysis procedures on the basis of a brief exemplary run.
Background and aim
Loss of time is a major obstacle to efficient stroke treatment. Our telestroke path intends to optimize prehospital triage using a video link connecting ambulance personnel and a ...stroke physician. The objectives were as follows: (1) To identify patients suffering a stroke and (2) in particular large vessel occlusion (LVO) strokes as candidates for endovascular treatment. We have chosen the Rapid Arterial Occlusion Evaluation (RACE) scale for this purpose.
Methods
This analysis aimed to verify the feasibility of prehospital stroke identification by video assessment. In this prospective telestroke cohort study, we included 97 subjects, in which the RACE score (items: facial palsy, arm and leg motor function, head and gaze deviation, and aphasia or agnosia) was applied, and the assessment videotaped by a trained member of the Emergency Medical Services (EMS) in the field using a mobile device. Each recorded patient video was independently assessed by three experienced stroke physicians from a certified stroke center and compared to the neuroimaging gold standard. Within this feasibility study, the stroke code was not altered by the outcome of the RACE assessment, and all patients underwent the standard procedures within the emergency unit.
Results
We analyzed 97 patients (median age 78 years, 53% women), of whom 51 (52.6%) suffered an acute stroke, 12 (23.5%) of which were due to an LVO and 46 patients had symptoms mimicking a stroke. The sensitivity of stroke identification was 77.8%, and specificity was 53.6%. In regard to the identification of an LVO, sensitivity was 69.4% and specificity was 84.3%. The inter-rater agreement in the RACE-score assessment was ICC = 0.82 (intraclass-correlation coefficient).
Conclusion
These results confirm our hypothesis that the local telestroke concept is feasible. It allows correct (i) stroke and (ii) LVO identification in the majority of the cases and thus has the potential to assist in efficient prehospital triage.
This paper analyses Levas Vladimirovas’ article “Karaliaučiaus spaudos pradininkas Hansas Veinreichas ir pirmieji jo darbo tęsėjai (XVI–XVII a.)” from 1961 with the aim to demonstrate his pioneering ...significance for the study of Königsberg book and library history from its beginnings in the 16th century until today. The first part of the following paper recapitulates the decisive contribution of the Lithuanian research in the clearing up of the fate of the libraries of old Königsberg. The second part of this paper deals with Vladimirovas’ study that updates a tradition of book historical research for future book science. After 1945 Vladimirovas was not only the first scientist, who has worked so intensely and objectively with the Königsberg printing during the early modern times, he was perhaps the first researcher taking a closer look at the books from the former Königsberg libraries that after 1945 had been brought by expert groups of the Lithuanian Academy of Sciences at first to Kaunas, then to Vilnius.
Nadav Na’aman’s recent dating of the Deuteronomic Law by social history is methodologically seminal, even if I disagree with the substance of his argument. In this article, I advance the case ...that the care of Deuteronomy for the ‘displaced Judahite” (גר) fits the 6th century much better than the 7th, as Na’aman argues.
The book of Samuel tells the story of the origins of kingship in Israel in what seems to be an artistically structured, flowing narrative. Yet it is also marked by an inconsistent outlook, divergent ...styles, and breaks in the narrative. According to Noth’s Deuteronomistic History hypothesis, the Deuteronomistic historian constructed the narrative by piecing together early sources and generally refrained from commenting in his own voice. Recent studies have called into question the extent of Samuel’s sources and their redaction history, as well as the textual growth of the book as a whole. The essays in this book, representing the latest scholarship on this subject, reexamine whether the book of Samuel was ever part of a Deuteronomistic History. The contributors are A.
