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. Elevated(More)
This paper proposes a novel CT image coding concept named LOI which stands for level of interest and coding methods based on that concept. The well-known ROI (region of interest) coding gives priority to pixels in particular regions of an image when encoding or decoding the image. Similarly, LOI coding gives priority to the pixels having a particular pixel(More)
In this paper, the authors propose a novel method to measure the perceived picture quality of H.264 coded video; based on hybrid no reference framework. The latter term means that the proposed model uses only receiver-side information for objective video quality assessment, but analyzes both the compressed bitstream and baseband signals of the decoded(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)
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 artifacts. To satisfy the requirement, some methods for MPEG-1 and MPEG-2 have been proposed. However, these methods cannot be(More)
