Nostoc flagelliforme is a terrestrial macroscopic cyanobacterium with a hair-like appearance that is distributed in arid and semi-arid areas. It exhibits remarkable tolerance to extremely acute or long-term dehydration stress. However  it cannot withstand prolonged hydration or water saturation. It appears that too little water limits its growth while too much water becomes a burden. This seemingly contradictory situation is particularly pronounced in N. flagelliforme  reflecting its distinctiveness among Nosotcspecies with respect to the ways they adapt to dry environments. In this review  we call attention to potentially important drought-adaptation mechanisms in this species  including mechanisms related to its morphology  structure  ecophysiology and genetic background  summarizing the available studies relevant to this topic. This species may become a good model for investigating the diverse genetic mechanisms of Nostoc adaptation to dry environments.

In order to overcome the distortion problem of CCD driving signals caused by signal transmission  the detail implementation of transmission of high-speed CCD driving signals based on transmission line theory is discussed. The CCD driving signals are critical to the CCD to produce high quality images. In high speed application these drivers will occupy more circuit board areas and can not be put very close to the CCD. So the driving signals must be transmitted. Because the CCD exhibits capacitive load  the driving signals distortion problem is much severe. Transmission line theory is used to analyze the problem. The method of source termination is adopted to avoid signal reflections. Meanwhile the characteristic impedance of the circuit board and the resistance of terminal resistor are designed small enough to decrease the rising and falling time of the driving signals. Experimental results show that there is no distortion of the high speed driving signals after transmission. 2011 IEEE.
