Centralspindlin is essential for central spindle and cleavage furrow formation. Drosophila centralspindlin consists of a kinesin-6 motor (Pav/kinesin-6) and a GTPase-activating protein (Tum/RacGAP). Centralspindlin localization to the central spindle is mediated by Pav/kinesin-6. While Tum/RacGAP has well-documented scaffolding functions, whether it influences Pav/kinesin-6 function is less wel...

Sädtler, Satellitennavigation mit Röntgenpulsaren, Diplomarbeit, LMU München (2009) We investigate the possibility of an autonomous navigation system based on pulsar timing data. Onboard a spacecraft, such a system can determin...

conclusions the levels of knowledge and skill among iranian physicians on major topics of sports and exercise medicine are low to medium. gps and interns are the first line of patient management so our findings suggest adding some sports medicine related topics into curriculum of medical doctors. materials and methods a cross-sectional study was performed in 2009 to determine the knowledge rega...

We study the interpixel cross talk introduced to digital holographic data storage by use of a multilevel phase mask at the data-input plane. We evaluate numerically the intensity distribution at the output detector for Fourier plane hologram storage in a limited-aperture storage medium. Only the effect at an output pixel of interpixel cross talk from the four horizontal and vertical neighboring...

To study the spiral wave in an unbounded excitable medium, we consider the wave front interaction model which derived by Zykov in 2007. This model consists of two systems of ordinary di↵erential equations which describe the wave front and wave back, respectively. First, we derive some properties of the back by shooting argument and comparison principle. Next we show the global existence of the ...

An overview is given of the attempts to understand the behavior of scroll waves in threedimensional excitable media using analytical methods, and these results are compared with recent numerical and experimental results. The behavior of untwisted planar scroll rings, twisted rings and helices, and knotted scroll wave filaments is discussed.

This work studies both theoretically and experimentally the formation of the contour interference patterns generated by a two-wavelength real-time holographic interferometer. The resulting contour interference fringes are due to the intersection of the measured surface with parallel, equally spaced planes of constant elevation. The theoretical analysis describes how the spatial frequency of the...
