A portable MBE system for in situ X-Ray investigations at synchrotron beamlines
A portable synchrotron MBE system is designed and applied for in situ
investigations. The growth chamber is equipped with all the standard MBE
components such as effusion cells with shutters, main shutter, cooling shroud,
manipulator, RHEED setup and pressure gauges. The characteristic feature of the
system is the beryllium windows which are used for in situ x-ray measurements.
An UHV sample transfer case allows in-vacuo transfer of samples prepared
elsewhere. We describe the system design and demonstrate it's performance by
investigating the annealing process of buried InGaAs self organized quantum
dots
Spontane durale arteriovenöse Fistel am Sinus cavernosus: Demaskierung nach endoskopischer Nasennebenhöhlen-Operation
Zusammenfassung: Spontane arteriovenöse Fisteln können sich über längere Zeit symptomlos entwickeln, bevor sie mit Strömungsgeräuschen, Visusminderung, Exophthalmos und konjunktivaler Injektion symptomatisch werden. Wir stellen den seltenen Fall einer okkulten parainfektiösen duralen arteriovenösen Fistel vor. Diese demaskierte sich postoperativ durch akute Verschlechterung der venösen Drainage, möglicherweise aufgrund der intraoperativen Lagerung, positiver Beatmungsdrucke und Stauung durch die Nasentamponad

Thrombolyse der Arteria cerebri media
Zusammenfassung: In den ersten 3h nach Eintritt eines akuten ischämischen Hirninfarkts ist die intravenöse Thrombolyse (IVT) die evidenzbasierte Therapie (IVT 3-4,5h: "off-label use" mit Einverständnis des Patienten). Die intraarterielle Thrombolyse (IAT) führt in der A.cerebri media (ACM) allerdings häufiger zur Rekanalisation als die IVT. Daher ist die IAT in dafür ausgerüsteten Kliniken ergänzend oder alternativ zur IVT bis zu 6h nach Symptombeginn zu erwäge
Multiresolution fuzzy clustering of functional MRI data
Recent developments in the analysis of functional MRI data reveal a shift from hypothesis-driven statistical tests to unsupervised strategies. One of the most promising approaches is the fuzzy clustering algorithm (FCA), whose potential to detect activation patterns has already been demonstrated. But the FCA suffers from three drawbacks: first the computational complexity, second the higher sensitivity to noise and third the dependence on the random initialization. With the multiresolution approach presented here, these weak points are significantly improved, as is demonstrated in our tests with simulated and real functional MRI dat
