Pinard, J, Duong, H T, Marescaux, D, Stroke, Hinko Henry, Redi, O, Gustafsson, M, ...

A precision measurement of the 126Cs(T1/2=1.63m) hfs separation Deltanu in the ground 6s^2S_1/2 state was obtained by means of atomic beam magnetic resonance on-line with the CERN-PSB-ISOLDE mass...

Grazing Eclipsing Dwarf Nova CW Monocerotis: Dwarf Nova-Type Outburst in a Possible Intermediate Polar? (2003)

Kato, T., Uemura, M., Kiyota, S., Tanabe, K., Koizumi, M., Kida, M., ...

We observed the 2002 October-November outburst of the dwarf nova CW Mon. The outburst showed a clear signature of a premaximum halt, and a more rapid decline after reaching the outburst maximum. On...

$\beta$ decay of the $M_{T}=-1$ nucleus $^{58}$Zn studied by selective laser ionization (1999)

Beta decay of \nuc{58}{Zn} has been studied for the first time. A new laser ion-source concept has been used to produce mass-separated sources for beta and gamma spectroscopy. The half-life of...

Production of Superconducting NbN Thin Plate and Wire by the Self-Propagating High-Temperature Synthesis Method. (1998)

Ohyanagi, M., Koizumi, M., Tanihata, K., Miyamoto, Y., Yamada, O.

Much progress has been made in the study of B1-NbN superconducting material for its very high critical field (H(c)) and critical current density (J(c)). Most attention concerning this superconductor...

Characteristic TiC Body Fabricated by Combustion Synthesis Using Reactant Compact with Density of More Than 80 Percent. (1998)

Ohyanagi, M., Koizumi, M., Kanno, M.

The combustion synthesis between Ti and C was performed using cylindrical specimens with relatively high green density (2.5-3.4 g/cc:65-89%). A TiC body with a densified surface layer was...

FIELD EMISSION PROPERTIES OF - ORIENTED CARBIDE TIPS (1987)

Ishizawa, Y., Koizumi, M., Oshima, C., Otani, S.

We report that -oriented TiC and NbC single crystal tips produce highly stable field emission currents after the surface-processing. The surface-processing consists of the tip heating at 900-1100°C...

MÖSSBAUER EFFECT OF SrLnFeO4 (Ln=La, Pr, Nd) (1979)

Shimada, M., Koizumi, M., Takano, M., Shinjo, T., Takada, T.

The Mössbauer effect has been studied in SrLaFeO4, SrPrFeO4, and SrNdFeO4, with K2NiF4 structure in the temperature range between 4 K and 640 K. The results of the combined magnetic and quadrupole...

Functional interleukin-2 receptors on intestinal epithelial cells.

Ciacci, C, Mahida, Y R, Dignass, A, Koizumi, M, Podolsky, D K

The presence of receptors for the cytokine IL-2 was assessed in the IEC-6 cell line established from normal rat crypt epithelium and primary intestinal epithelial cells. 125I-IL-2 was found to...

Cross-ligation and exchange reactions catalyzed by hairpin ribozymes.

Komatsu, Y, Koizumi, M, Sekiguchi, A, Ohtsuka, E

The negative strand of the satellite RNA of tobacco ringspot virus (sTobRV(-)) contains a hairpin catalytic domain that shows self-cleavage and self-ligation activities in the presence of magnesium...

Design of RNA enzymes distinguishing a single base mutation in RNA.

Koizumi, M, Hayase, Y, Iwai, S, Kamiya, H, Inoue, H, Ohtsuka, E

RNA enzymes (ribozymes) which can cleave RNA by recognizing sequences of 9-15 bases are described. Substrates must contain UX (X = U, C or A). A ribozyme consisting of two oligoribonucleotides (19...

Mutagenesis and self-ligation of the self-cleavage domain of the satellite RNA minus strand of tobacco ringspot virus and its binding to polyamines.
