The present invention relates to organic molecules capable of modulating tyrosine kinase signal transduction in order to regulate, modulate andor inhibit abnormal cell proliferation. When a fluid traveling through a subject is imaged for multiple times at different phases, the determining unit determines a period on the time axis within which imaging is performed at intervals satisfying a predetermined temporal resolution. The operations may be specified in an instruction issued by the pageable guests. Each light emitting micromesa has a topmost layer of a second conductivity type that is opposite the first conductivity type. In some examples, third harmonic generation is used for imaging of conductive layers.
