被引用回数：8 パーセンタイル：87.49(Multidisciplinary Sciences)This paper presents a multidisciplinary analysis of the Fukushima Daiichi Nuclear Power Plant accident. Along with the latest observations and simulation studies, we synthesize the time-series and event progressions during the accident across multiple disciplines. We identify three key factors that exacerbated the consequences of the accident: (1) the failure of Unit 2 containment venting, (2) the insufficient integration of radiation measurements and meteorology data in the evacuation strategy, and (3) the limited risk assessment and emergency preparedness. We conclude with new research and development directions to improve the resilience of nuclear energy systems and communities, including (1) meteorology-informed proactive venting, (2) machine learning-enabled adaptive evacuation zones, and (3) comprehensive risk-informed emergency planning while leveraging the experience from responses to other disasters.

被引用回数：18 パーセンタイル：67.02(Physics, Multidisciplinary)The possibility of phase-contrast imaging of nanostructures has been analyzed with the use of solid targets irradiated by femtosecond laser pulses as a spatially coherent soft X-ray source and a LiF crystal as an X-ray detector having both the submicron spatial resolution in a wide field of view and a high contrast. It has allowed to obtain high-quality phase-contrast X-ray images of foils with various chemical compositions and a thickness of about 100 nm.

被引用回数：26 パーセンタイル：72.50(Optics)Elemental sensitivity in soft X-ray imaging of thin foils with known thickness is observed using an ultrafast laser-plasma source and a LiF crystal as detector. Measurements are well reproduced by a simple theoretical model. This technique can be exploited for high spatial resolution, wide field of view imaging in the soft X-ray region, and it is suitable for the characterization of thin objects with thicknesses ranging from hundreds down to tens of nanometers.
