Abstract Deep brain stimulation (DBS) is a neurosurgical intervention where electrodes are permanently implanted into the brain in order to modulate pathologic neural activity. The post-operative reconstruction of the DBS electrodes is important for an efficient stimulation parameter tuning. A major limitation of existing approaches for electrode reconstruction from post-operative imaging that prevents the clinical routine use is that they are manual or semi-automatic, and thus both time-consuming and subjective. Moreover, the existing methods rely on a simplified model of a straight line electrode trajectory, rather than the more realistic curved trajectory. The main contribution of this paper is that for the first time we present a highly accurate and fully automated method for electrode reconstruction that considers curved trajectories. The robustness of our proposed method is demonstrated using a multi-center clinical dataset consisting of N=44 electrodes. In all cases the electrode trajectories were successfully identified and reconstructed. In addition, the accuracy is demonstrated quantitatively using a high-accuracy phantom with known ground truth. In the phantom experiment, the method could detect individual electrode contacts with high accuracy and the trajectory reconstruction reached an error level below 100 μm (0.046 ± 0.025 mm). An implementation of the method is made publicly available such that it can directly be used by researchers or clinicians. This constitutes an important step towards future integration of lead reconstruction into standard clinical care. [less ▲]

Pacing-induced ventricular dysfunction and pacing-induced cardiomyopathy (PiCMP) are recognized complications of chronic right ventricular pacing. Alterations in myocardial perfusion and sympathetic innervation contribute to the development of pacing-induced heart disease. However, it is unlikely that these are the only processes involved. Matrix metalloproteinases (MMPs) are proteolytic enzymes that degrade the collagenous extracellular matrix and play a central role in left ventricular remodelling during the development of heart failure. While the pathophysiological mechanisms and altered MMP expression that occur in chronic pressure overload, ischaemic and non-ischaemic dilated cardiomyopathy have been defined, those that occur in the clinical setting of pacing-induced ventricular dysfunction and PiCMP have not been reported. Here we review the clinical epidemiology of pacing-induced ventricular dysfunction and discuss how data derived from animal models provide insight into how changes in MMP expression and function contribute to the development of PiCMP. The review concludes by exploring pacing strategies that may be used to prevent pacing-induced ventricular dysfunction. [less ▲]

Wireless local area networks experience performance degradation in presence of small packets. The main reason for that is the large overhead added at the physical and link layers. This paper proposes a concatenation algorithm which groups IP layer packets prior to transmission, called PAC-IP. As a result, the overhead added at the physical and the link layers is shared among the grouped packets. Along with performance improvement, PAC-IP enables packet-based fairness in medium access as well as includes QoS support module handling delay-sensitive traffic demands. The performance of the proposed algorithm is evaluated through both simulations and an experimental WLAN testbed environment covering the single-hop and the widespread infrastructure network scenarios. Obtained results underline significant performance enhancement in different operating scenarios and channel conditions. [less ▲]

Die Transformation von „Wert und Norm“ in „Theorie und Praxis“ ist zwar populär, erfüllt aber, so die These dieses Artikels, nicht den wissenschaftli-chen Anspruch, Praktiken – das können auch diskursive Praktiken sein – in ihren Normativitäten zu beschreiben und dazu Theorien zu formulieren, son-dern stellt sich in den Dienst dominanter Wertvorstellungen, statt diese mit Distanz zu reflektieren. Die Pädagogik als Wissenschaft stellte sich überwiegend in den Dienst der Werte, d.h. des vermeintlich Guten, und entwickelte dadurch Normvorstellungen. Diese sind oft diffus und schwer umzusetzen, sicher aber nicht empirisch abgesichert, und sie lassen die tatsächlich beobachtbaren und gemessenen Normen als stets defizitär erscheinen. Eine Kulturgeschichte des Berufsstands der Lehrer könnte über die Auswirkungen dieses Wissenschafts-verzichts – d.h. keine Distanz zu den Werten aufzubringen und sich fraglos in deren Dienst zu stellen – der Erziehungswissenschaft eindrücklich Auskunft geben.
