One of the advantages of atomic force microscopy (AFM) is that it can accurately measure the heights of targets on flat substrates. It is difficult, however, to determine the shape of nanoparticles on rough surfaces. We therefore propose a curvature-reconstruction method that estimates the sizes of particles by fitting sphere curvatures acquired from raw(More)
This paper presents the novel frequency tunable CRLH-TL (Composite Right/Left-Handed transmission line) using varactor diodes for the reconfigurable wireless systems. Varactor diodes are implemented into the CRLH unit cell as the series capacitor. Proposed frequency tunable CRLH-TL indicates the variable EBG (Electromagnetic Band Gap) bandwidths with(More)
We observed whether or not there were eggs, larvae, pupae, and empty pupal shells of flies on cadavers found outdoors in Sapporo, the northern district of Japan (43 degrees N). The temperature has an influence on the oviposition of flies. The average season in which flies lay eggs is from the middle of April to the beginning of November, although there is a(More)
