Dedicated to Professor A Ifred Klemm on the occasion of his 70th birthday In platelets of Cs2Zn3S4 with about 4% of the Zn substituted by Mn two nonequivalent centers of isolated Mn + were observed in addition to a broad EPR signal near g = 2 which is assigned to clusters of interconnected MnS4 units. The fine structure and hyperf ine structure parameters for the single-ion centers (all in unit...

In distributed multimedia applications time-dependent data streams are conveyed and processed under real-time conditions. The timely accurate activation of the stream handlers processing the data units of streams requires deriving their scheduling times from the temporal properties of the data streams and the amount of data that is processed in each activation. In this paper, we propose the act...

How the cardiomyocytes are aggregated within the heart walls remains contentious. We still do not fully understand how the end-to-end longitudinal myocytic chains are arranged, nor the true extent and shape of the lamellar units they aggregate to form. In this article, we show that an understanding of the complex arrangement of cardiac musculature requires knowledge of three-dimensional myocyte...

Psychophysical studies suggest the existence of specialized detectors for component motion patterns (radial, circular, and spiral), that are consistent with the visual motion properties of cells in the dorsal medial superior temporal area (MSTd) of non-human primates. Here we use a biologically constrained model of visual motion processing in MSTd, in conjunction with psychophysical performance...

In this paper control systems design approach, based on siding mode methods, that allows maintain some functional relation – like bilateral or multilateral systems, establishment of virtual relation among mobile robots or control of haptic systems is presented. It is shown that all basic motion control problems trajectory tracking, force control, hybrid position/force control scheme and the imp...

Mappings between ontologies are easily harmed by changes in the ontologies. In this paper we explain a mechanism to define modular ontologies and mappings in a way that allows for local containment of terminological reasoning. We have also developed a change detection and analysis method that predicts the effect of changes on the concept hierarchy. This method determines whether the changes in ...
