Synthesis Method for Ternary Logic Function Based on Nand-Type Polypheck, (9999)

Yanagita,M., Fukuda,N., Miyoshi,Y., Nakashima,K., Yamato,K.

This paper studies the synthesis of ternary logic functions based on a NAND-type polypheck. The size of term is the arithmetic sum of its truth values over all assignments of variable values. It...

Measurements of Atmospheric Antiprotons (2005)

Yamato, K., Abe, K., Fuke, H., Haino, S., Makida, Y., Matsuda, S., ...

We measured atmospheric antiproton spectra in the energy range 0.2 to 3.4 GeV, at sea level and at balloon altitude in the atmospheric depth range 4.5 to 26 g/cm^2. The observed energy spectra,...

Search for Cosmic-Ray Antideuterons (2005)

Fuke, H., Maeno, T., Abe, K., Haino, S., Makida, Y., Matsuda, S., ...

We performed a search for cosmic-ray antideuterons using data collected during four BESS balloon flights from 1997 to 2000. No candidate was found. We derived, for the first time, an upper limit of...

Measurement of Cosmic-Ray Proton, Antiproton and Muon Spectra at Mountain Altitude (2003)

Sanuki, T., Fujikawa, M., Abe, K., Anraku, K., Fuke, H., Haino, S., ...

Measurement of cosmic-ray proton, antiproton and muon spectra was carried out at mountain altitude. We observed 2 x 10^5 protons and 10^2 antiprotons in a kinetic energy region of 0.25 -- 3.3 GeV....

Measurements of Proton, Helium and Muon Spectra at Small Atmospheric Depths with the BESS Spectrometer (2003)

Abe, K., Sanuki, T., Anraku, K., Asaoka, Y., Fuke, H., Haino, S., ...

The cosmic-ray proton, helium, and muon spectra at small atmospheric depths of 4.5 -- 28 g/cm^2 were precisely measured during the slow descending period of the BESS-2001 balloon flight. The...

Measurements of atmospheric muon spectra at mountain altitude (2002)

Sanuki, T., Fujikawa, M., Abe, K., Anraku, K., Asaoka, Y., Fuke, H., ...

We report new measurements of the atmospheric muons at mountain altitude. The measurement was carried out with the BESS detector at the top of Mt. Norikura, Japan. The altitude is 2,770 m above sea...

Precise Measurements of Atmospheric Muon Fluxes with the BESS Spectrometer (2002)

Motoki, M., Sanuki, T., Orito, S., Abe, K., Anraku, K., Asaoka, Y., ...

The vertical absolute fluxes of atmospheric muons and muon charge ratio have been measured precisely at different geomagnetic locations by using the BESS spectrometer. The observations had been...

Measurements of Cosmic-ray Low-energy Antiproton and Proton Spectra in a Transient Period of the Solar Field Reversal (2001)

Asaoka, Y., Shikaze, Y., Abe, K., Anraku, K., Fujikawa, M., Fuke, H., ...

The energy spectra of cosmic-ray low-energy antiprotons and protons have been measured by BESS in 1999 and 2000, during a period covering the solar magnetic field reversal. Based on these...

Influence of Carbon and Nitrogen on Corrosion Resistance of High Purity Fe-50mass % Cr Alloy (1995)

Kato, Y., Ujiro, T., Satoh, S., Yamato, K., Abiko, K.

High purity Fe-50mass%Cr alloys containing (C+N) in the range of 30 to 500 mass ppm were prepared and their corrosion resistance was investigated. Pitting potential in a 3.5mass%NaCl solution at 343K...

Role of CD14 molecules in internalization of Actinobacillus actinomycetemcomitans by macrophages and subsequent induction of apoptosis.

Muro, M, Koseki, T, Akifusa, S, Kato, S, Kowashi, Y, Ohsaki, Y, ...

We report the evidence for apoptosis in J774.1 cells by the periodontopathic bacterium Actinobacillus actinomycetemcomitans, suggesting that the ability of A. actinomycetemcomitans to promote...

Modulation of interleukin-1 beta RNA in monocytic cells infected with human immunodeficiency virus-1.

Yamato, K, El-Hajjaoui, Z, Simon, K, Koeffler, H P

The effect of HIV-1 infection on cytokine levels was studied in monocytic cells by using Northern blotting analysis. Monoblasts (THP-1, U937) did not express IL-1 beta RNA even if the cells were...
