Dipolar-driven mean-field criticality in the ferrimagnet EuMnSiO
Masahiro Kawamata, Maxim Avdeev, Yusuke Nambu
We report mean-field critical behavior in EuMnSiO, a melilite-type ferrimagnet with spin-only Eu and Mn moments and negligible orbital contributions. Magn…
Statistics of Solar Filament Mass based on CHASE Sun-as-a-star Spectroscopic Observations
T. Y. Xie, Z. H. Zhao, X. Cheng +5
Filaments are cool and dense plasmas suspended in the hot corona of the Sun and other stars. Accurately estimating their masses is of great significance for understanding subsequen…
Free-Horizon Newton Method for Nonlinear Optimal Control
Gyeongrok Ha, Kenji Fujimoto, Ichiro Maruta
This paper presents a novel trajectory optimization method for nonlinear l1-optimal control problems in which the control horizon is treated as a free variable, allowing both the c…
Radio Constraints on the Circumstellar Environment of the Type IIb Supernova SN 2024iss
Yuhei Iwata, Tomoki Matsuoka, Masanori Akimoto +6
Type~IIb supernovae exhibit diverse progenitor properties, and radio observations offer a unique probe of their mass-loss histories shortly before the explosion. We present Japanes…
Emotion Dynamics in Social Deception Games: Analysis of Professional and Nonprofessional Players through Electrodermal Activity in Werewolf Games
Sho Mitarai, Chang Liu, Goshiro Yamamoto +1
The development of AI systems capable of emotionally resonant communication remains a significant challenge. This study examines how humans influence emotions in social deception g…
Estimation of Condition Number of Quasi-static Darwin Model
Shingo Hiruma, Takeshi Mifune, Tetsuji Matsuo
This study discusses the estimation of the condition number of the quasi-static Darwin model, which is shown to be a nearly singular system of equations with a large kernel derived…
