Welcome to the world of Martin "Buzzy" Schwartz, Champion Trader--the man whose nerves of steel and killer instinct in the canyons of Wall Street earned him the well-deserved name "Pit Bull." This is the true story of how Schwartz became the best of the best, of the people and places he discovered along the way and of the trader’s tricks and techniques he used to make his millions.
Spontaneous activities in resting skeletal musculature in humans occur under different physiological conditions, but changes in their spatio-temporal patterns can also indicate neuromuscular disease or abnormality. These are currently detected by diagnostic techniques, such as invasive needle electromyography or non-invasive muscle sonography, and clinically classified on the basis of their temporal pattern and rate of occurrence. However, the available clinically established diagnostic techniques are not only in part invasive but are also spatially limited and therefore can only provide very localized information about the spontaneous activities of resting musculature. Moreover, a whole-body examination or the inspection of several different muscle groups requires multiple consecutive invasive procedures to assess the current state of the resting musculature. Magnetic Resonance Imaging (MRI), as a non-invasive, three-dimensional imaging measurement technique, has the potential to address these limitations of established diagnostic techniques and to complement them. In particular, Diffusion-Weighted (DW)-MRI could make an important contribution due to its inherent sensitivity with respect to all kind of incoherent motion. This work focuses on the technical aspects and characteristics of visualizing unique spontaneous activities of resting human musculature by DW-MRI in combination with simultaneously recorded non-invasive Surface ElectroMyoGraphy (sEMG) measurements. Within the scope of this thesis, the physiological relationships between signal voids visible in diffusion-weighted images and single myoelectric spontaneous activities are identified. On this basis, image acquisition is optimized to this specific and challenging task using state-of-the-art imaging techniques and newly introduced concepts.
Rebeka jedného dňa objavila na paneláku zvláštny svet. Svet postavičiek zo steny. Nie sú úplne dokonalé, ale Rebeka im rada pomôže. Stačia jej k tomu farebné kriedy. Ešte nikdy nemala toľko kamarátov a teraz hrozí, že o nich príde. Panelákovú stenu sa totiž chystajú premaľovať. Zachránia ich Rebekine farbičky aj tentoraz?
