Multi-layer scintillation detector for the MOON double beta decay experiment: Scintillation photon responses studied by a prototype detector MOON-1 (2006)

Nakamura, H., Doe, P., Ejiri, H., Elliott, S. R., Engel, J., Finger, M., ...

An ensemble of multi-layer scintillators is discussed as an option of the high-sensitivity detector Mo Observatory Of Neutrinos (MOON) for spectroscopic measurements of neutrino-less double beta...

Increased TUNEL positive cells in human alcoholic brains (2003)

Ikegami, Y, Goodenough, S, Inoue, Y, Dodd, PR, Wilce, PA, Matsumoto, I

Alcohol-sensitive neuronal cell loss, which has been reported in the superior frontal cortex and hippocampus, may underlie the pathogenesis of subsequent cognitive deficits. In the present study, we...
