Uchu Seibutsu Kagaku, 2002 Astronauts were constantly exposed to space radiation containing various kinds of energy with a low-dose rate during long-term stays in space. Therefore, it is important to judge correctly the biological effect of space radiation for human health. In addition, research for space radiation might give us useful information concerning birth and evolution ...

Tensor Network Models of Unitary Black Hole Evaporation
, 2017 We introduce a general class of toy models to study the quantum information-theoretic properties of black hole radiation. The models are governed by a set of isometries that specify how microstates of the black hole at a given energy evolve to entangled ...

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Lunar radiation environment: Measurement and modeling results
地球与行星物理论评The exploration of the Moon is an extremely important part of aerospace missions. However, the Moon lacks the shielding of a global magnetic field and atmosphere, leaving it directly exposed to high energy space radiation, which poses non-negligible ...
