We demonstrated a novel optical switch to control the high-order harmonic generation
process so that single attosecond pulses can be generated with multiple-cycle pulses. The …

The hypothalamus is a central regulator of many behaviors that are essential for survival,
such as temperature regulation, food intake and circadian rhythms. However, the molecular …

Isolated attosecond pulses are powerful tools for exploring electron dynamics in matter. So
far, such extreme ultraviolet pulses have only been generated using high power, few-cycle …

[Background] On 11 March 2011, the Great East Japan Earthquake followed by a gigantic
tsunami hit the Pacific coast of Northeast Japan (Tohoku) and damaged Tokyo Electric …

Abstract Two-color (800 and 400 nm) short (45 fs) linearly polarized pulses are used to
ionize and dissociate D 2 into a neutral deuterium atom and a deuteron. The yields and …

Objective To assess relationships between the perception of radiation risks and
psychological distress among evacuees from the Fukushima nuclear power plant disaster …

High-speed photonic and electronic devices at present rely on radiofrequency electric fields
to control the physical properties of a semiconductor, which limits their operating speed to …

Laser-dressed absorption in atomic helium is studied, both theoretically and experimentally,
by transient absorption spectroscopy using isolated 400-as pulses centered at 22 eV and 12 …

We used a liquid phase reaction to synthesize a nickel (Ni) and iron (Fe)-containing layered
double hydroxide (NiFe-LDH), having a lateral size less than 10 nm. A chelating agent …

On March 11, 2011, the Great East Japan Earthquake occurred in Japan, with a nuclear
accident subsequently occurring at the Fukushima Daiichi Nuclear Power Plant. The …
