Two-Dimensional AOA Estimation Based on a Constant Modulus Algorithm
International Journal of Antennas and Propagation, 2017 We propose a two-dimensional (2D) angle of arrival (AOA) estimator using the algebraic constant modulus algorithm (ACMA). This algorithm was originally introduced to estimate the one-dimensional (1D) AOA.

Ryugu reference project: Recommendations from the measurement definition team
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 819-848, May 2026.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

Impact of ENSO on Nitrous Oxide Emissions in the Eastern Tropical Pacific
Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.Abstract Nitrous oxide (N2O ${\mathrm{N}}_{2}\mathrm{O}$) is a powerful greenhouse gas, with the ocean contributing ∼4.2 Tg N y−1 to global N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions. The Eastern Tropical Pacific (ETP) is a hotspot of N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions due to high N2O ${\mathrm{N}}_{2}\mathrm{O}$ production under low‐oxygen ...
