PURPOSE To evaluate a standardized definition of delayed hyperenhancement in the analysis of contrast-enhanced cardiac magnetic resonance (ceCMR) imaging. PATIENTS AND METHODS CeCMR was performed in 15 patients with chronic ischemic heart disease. Delayed hyperenhancement was analyzed both by visual analysis by an experienced team of observers, and after(More)
BACKGROUND Quantification of late gadolinium enhanced cardiovascular magnetic resonance (LGE CMR) by objective window setting increases reproducibility and facilitates multicenter comparison and cooperation. So far, quantification methods or models have only been validated to postmortem animal studies. This study was undertaken to evaluate quantification of(More)
The Great Barrier Reef (GBR) in Australia consists of 3200 coral reefs extended over 280,000 km 2. Coral reef ecosystems are areas greatly susceptible to impact of global climate change as well as other man-made influences. This creates an urgent demand for the sensor network technologies to be deployed in order to perform essential environmental monitoring(More)
This demo dramatically illustrates how replacing 'Classic' TCP congestion control (Reno, Cubic, etc.) with a 'Scalable' alternative like Data Centre TCP (DCTCP) keeps queuing delay ultra-low; not just for a select few light applications like voice or gaming, but even when a variety of interactive applications all heavily load the same (emulated) Internet(More)
This paper concerns the use of Active Queue Management (AQM) to reduce queuing delay. It offers insight into why it has proved hard for a Proportional Integral (PI) controller to remain both responsive and stable while controlling `Classic' TCP flows, such as TCP Reno and Cubic. Due to their non-linearity, the controller's adjustments have to be smaller(More)
We compared the characteristics of EEG during mono- and binocular performance of the Stroop test. Either emotionally colored words or “pseudowords” were presented as stimuli; among 60 examined subjects, there were 30 sinistrals with dominant left eye and 30 dextrals with dominant right eye. In right-handed subjects, the coherence of theta oscillations in(More)
The role of environmental ion composition and osmolality in Ca2+ signaled activation was assessed in spermatozoa of brook trout Salvelinus fontinalis. Milt from ten mature males was obtained by abdominal massage. Spermatozoa motility was evaluated in 0, 100, and 300 mOsm/kg NaCl or sucrose solutions, buffered by 10 mM Tris–HCl pH 8.5. For investigation of(More)
After administration of endocannabinoid-like compound N-stearoylethanolamine (NSE) at a dose of 0,1 and 5 mg/kg the anxiety level of rats in the elevated plus maze and learning ability of rats in the radial maze were investigated. It was revealed that NSE can change both innate and acquired behavior of rats. It was found that the administration of NSE(More)
Studies on the Cajander larch (Larix cajanderi) in the Amur region have been performed to evaluate the effect of growth conditions on the development of wood anatomical structure during ontogeny, including the course and rate of definitive (mature) wood formation. Adaptive changes in wood anatomy have been revealed in trees growing in waterlogged areas(More)
Background: In cardiac syndrome X, which is a syndrome defined as chest pain, positive exercise stress testing and/or reversible myocardial perfusion defects during myocardial scintigraphy and normal coronary angiograms, the ischemic origin is still debated. No previous study compared the myocardial perfusion in stress first-pass cardiac magnetic resonance(More)
