Aluminum dynamics in nitrogen‐saturated Andisols in Tokyo

Ecological Research, Volume 40, Issue 3, Page 293-302, May 2025.
Atmospheric nitrogen (N) deposition in throughfall has decreased in forests around the Tokyo metropolitan area. The present study was conducted to elucidate the effect of decreased nitrogen deposition on aluminum (Al) dynamics in a forested allophanic Andisols. Mobilization of Al tended to decrease, in particular in the Japanese cedar stand.

Quasar Luminosity Function at z = 7

The Astrophysical Journal Letters, 2023
We present the quasar luminosity function (LF) at z = 7, measured with 35 spectroscopically confirmed quasars at 6.55 < z < 7.15. The sample of 22 quasars from the Subaru High- z Exploration of Low-Luminosity Quasars (SHELLQs) project, combined with 13 ...

Spatiotemporal Variations and Postseismic Relaxation Process Around Mt. Fuji, Japan, During and After the 2011 Tohoku‐Oki Earthquake

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 2, February 2024.
Abstract To monitor the volcanoes at a high spatiotemporal resolution, we introduce the singular value decomposition‐based Wiener filter and the three‐component waveforms in ambient noise velocity monitoring. The continuous ambient noise data from 63 stations around Mt. Fuji and Mt.
