被引用回数：18 パーセンタイル：73.04(Materials Science, Multidisciplinary)Spintronics devices utilizing a magnetic domain wall motion have attracted increasing attention, and ferrimagentic materials with almost compensated magnetic moments are highly required to realize the fast magnetic domain wall motion. Here, we report a key function for this purpose in anti-perovskite CoMnN films. Perpendicular magnetization emerges for

Gcp was first identified in 
as an extracellular 
-sialoglycoprotein endopeptidase. Genome comparison revealed that all the free-living organisms, from bacteria to humans, possess its orthologues in an evolutionary-conserved manner. Moreover, the orthologues are highly essential in bacteria, including 
, 
and yeast, indicating that Gcp has other function(s) related to essentiality of life. The orthologues of 
and 
were deleted by replacement with antibiotic-resistant genes. Although both deletion mutants showed a little slower growth in rich media, successful gene disruption indicates that the orthologues are not essential in these bacteria. In this work we showed that orthologues of 
and 
were not essential, but the mutants showed different phenotypes, osmosensitivity and sensitivity to DNA-damaging agents, respectively.

核分裂で放出されるガンマ線の高精度測定による核分裂過程や中性子過剰な原子核の研究を進めるため、通常の測定で良く用いられているシリコン半導体検出器と比較して安価で耐放射線性に優れる太陽電池を核分裂片の観測に用いる核分裂片検出器の開発を進めている。本発表ではCm-248自発核分裂を用いた測定で得られた太陽電池の核分裂片に対する応答について報告する。
