The regime of electromagnetically induced transparency in optically dense media: from atoms to excitons [PDF]

open access: yes, 2001
The phenomenon of electromagnetically induced transparency (EIT) was discovered by Adriano Gozzini and coworkers in 1976 in Pisa. Novel schemes to investigate and exploit EIT in the optical domain have attracted much interest both in atomic and solid ...

Language learning theories and cooperative learning techniques in the EFL classroom [PDF]

open access: yes, 2006
教育現場におけるグループ活動では、学生は小さなグループでタスクの達成に取り組むことが多い。しかし、全てのグループ活動がグループメンバー全員に平等な学習の機会を与えているわけではない。協同学習の技術を用いることで、教師は教室の中でより効果的にグループ活動を構成し、導入することができる。本稿では、まず、よく知られる第二言語習得に関する認知理論や社会文化理論を議論する。そして、協同活動がこれらの理論を反映しているばかりでなく、EFL学習状況(外国語として英語を学ぶ状況)という ...

Future changes in snowmelt-driven runoff timing over the western US [PDF]

open access: yes, 2009
We use a high-resolution nested climate model to investigate future changes in snowmelt-driven runoff (SDR) over the western US. Comparison of modeled and observed daily runoff data reveals that the regional model captures the present-day timing and ...
