(GaMn)As: GaAs-based III–V diluted magnetic semiconductors grown by molecular beam epitaxy
Takeshi Hayashi,Masaaki Tanaka,Masaaki Tanaka,Tatau Nishinaga,H. Shimada,H. Tsuchiya,Y. Otuka +6 more
TL;DR: In this article, a III-V diluted magnetic semiconductors (Ga 1-x Mn x )As were grown on GaAs substrates by low-temperature molecular beam epitaxy using strong nonequilibrium growth conditions.
Journal ArticleDOI
Spin-Vacancy-Induced Long-Range Order in a New Haldane-Gap Antiferromagnet
Yasunobu Uchiyama,Yoshitaka Sasago,Ichiro Tsukada,Kunimitsu Uchinokura,Andrey Zheludev,Takeshi Hayashi,N. Miura,Peter Böni +7 more
TL;DR: The first observation of doping-induced long-range order in a Haldane-gap system was made in this paper, where a quasi-one-dimensional antiferromagnet was shown to have a magnetically ordered state at low temperatures.
Journal ArticleDOI
Pepper mild mottle virus as an indicator and a tracer of fecal pollution in water environments: comparative evaluation with wastewater-tracer pharmaceuticals in Hanoi, Vietnam.
Keisuke Kuroda,Norihide Nakada,Seiya Hanamoto,Manami Inaba,Hiroyuki Katayama,An Thuan Do,Tran Thi Viet Nga,Kumiko Oguma,Takeshi Hayashi,Satoshi Takizawa +9 more
TL;DR: In this article, the authors compared the occurrence and fates of pepper mild mottle virus (PMMoV) with pharmaceuticals and personal care products (PPCPs), which are known wastewater tracers.
Journal ArticleDOI
Neuroprotective Role of a Proline-Rich Akt Substrate in Apoptotic Neuronal Cell Death after Stroke: Relationships with Nerve Growth Factor
Atsushi Saito,Purnima Narasimhan,Takeshi Hayashi,Shuzo Okuno,Michel Ferrand-Drake,Pak H. Chan +5 more
TL;DR: The results suggest that PRAS phosphorylation and its interaction with pAkt and 14-3-3 might play an important role in neuroprotection mediated by NGF in apoptotic neuronal cell death after tFCI.
Journal ArticleDOI
Effects of human activities and urbanization on groundwater environments: An example from the aquifer system of Tokyo and the surrounding area
TL;DR: The results suggest that the groundwater flow which was affected by urbanization (groundwater withdrawals) has continued to change over several decades, even after the regulation of withdrawals, and hence, the continued monitoring of the groundwater environment is important for the sustainable use of groundwater resources.
