We have constructed and tested a novel plastic-scintillator-based solid-state active proton target for use in nuclear spectroscopic studies with nuclear reactions induced by an ion beam in inverse kinematics. The active target system, named Stack Str

Joint Defogging and Demosaicking

Autor: Lee, Y. J., Hirakawa, K., Nguyen, T. Q.

Image defogging is a technique used extensively for enhancing visual quality of images in bad weather condition. Even though defogging algorithms have been well studied, defogging performance is degraded by demosaicking artifacts and sensor noise amp

Electrically tunable three-dimensional g-factor anisotropy in single InAs self-assembled quantum dots

Autor: Takahashi, S., Deacon, R. S., Oiwa, A., Shibata, K., Hirakawa, K., Tarucha, S.

Three-dimensional anisotropy of the Lande g-factor and its electrical modulation are studied for single uncapped InAs self-assembled quantum dots (QDs). The g-factor is evaluated from measurement of inelastic cotunneling via Zeeman substates in the Q
