In fission yeast, calcineurin dephosphorylates and activates the Prz1 transcription factor. Here, we identified the calcineurin-dependent response element (CDRE) in the promoter region of prz1(+) gene and monitored the calcineurin activity in living cells using a destabilized luciferase reporter gene fused to three tandem repeats of CDRE.

moving here this April, he had been working in KDDI Labs in the field of multimedia communications such as image processing, visual communications, and biometrics. This paper reports his some research work in the time of the senior manager of KDDI Labs. Firstly, the overview of KDDI Labs is briefly introduced. Then, his research work, such as super high(More)
Appropriate rate control plays a very important role in encoding motion pictures under the constant bit-rate. One of the requirements for rate control is minimizing temporal fluctuations in picture quality, which may cause flicker arti-facts. To satisfy the requirement, some methods for MPEG-1 and MPEG-2 have been proposed. However, these methods cannot be(More)
This paper presents a novel method to represent a real 3D world using IBR (Image-based Rendering) technology. The major achievement is realization of "walk-through" experience, in which audiences can see the scene of sport games as if they were the player, while the conventional IBR method cannot provide such an experience. The key idea is a newly(More)
