A guarantee obligation of keeping a Static-Noise-Margin (SNM), a Write-Margin (WRTM), and a cell current (Icell) even against a simultaneous Read/Write (R/W) disturbed access at the same column is...
YAMAUCHI, Hiroyuki, SUZUKI, Toshikazu, YAMAGAMI, Yoshinobu
Fundamental limitation on assisting a write margin (WRTM) by reducing the cell terminal bias (VDDM) [1], [2] has been made clear for the first time and the new cell terminal biasing scheme featuring...

Human small fragment nuclease (Sfn) is one of the cellular proteins that were reported to degrade small, single-stranded DNA and RNA. However, the biological role of Sfn in cellular response to...
Laser Stripping via a Broad Stark State for a High-Intensity Proton Ring (2002)
Yamane, Isao, Suzuki, Toshikazu, Takayama, Ken
A new type of charge-exchange injection scheme for high-intensity proton rings that use a laser beam and an undulator magnet is proposed. The elementary stripping process is resonant photoionization...

We evaluated the performance of polished mirror surfaces for the TAMA interferometric gravitational wave detector by comparing the experimental results with a wave-front tracing simulation. The TAMA...
YOUNG-OK KIM, TOSHIKAZU SUZUKI, AKIRA TANIGUCHI
Cysts of an oligotrich ciliate were collected from natural sediment samples in Onagawa Bay, northeastern coast of Japan, and examined for their excystment capability. A high excystment ratio was...
Thermal lensing in cryogenic sapphire substrates (2002)
Tomaru, Takayuki, Suzuki, Toshikazu, Miyoki, Shinji, Uchiyama, Takashi, Taylor, C. T., Yamamoto, Akira, ...
We report the reduction of the thermal lensing in cryogenic sapphire mirrors, which is planed to be used in the Large scale Cryogenic Gravitational wave Telescope (LCGT) project. We measured three...
Binding of 5-bromouracil-containing S/MAR DNA to the Nuclear Matrix (2002)
Ogino, Hideki, Fujii, Michihiko, Satou, Wataru, Suzuki, Toshikazu, Michishita, Eriko, Ayusawa, Dai
Substitution of thymine with 5-bromouracil in DNA is known to change interaction between DNA and proteins, thereby inducing various biological phenomena. We hypothesize that A/T-rich scaffold/nuclear...
The Human MYOD1 Transgene Is Suppressed by 5-Bromodeoxyuridine in Mouse Myoblasts (2002)
