Stability of constant steady states of an attraction-repulsion chemotaxis system
Hiroshi Wakui, Tetsuya Yamada
The Cauchy problem for the attraction-repulsion chemotaxis system in the whole -dimensional space has uncountable constant steady states. In the attraction chemotaxis system, ea…
Water Maser Disk and a Supermassive Black Hole at the Nucleus of the Active Galaxy NGC 7738
Rinka Ito, Yusuke Miyamoto, Naomasa Nakai +2
We present the results of very long baseline interferometry (VLBI) observations of water vapor masers in the nucleus of the LINER galaxy NGC 7738. The red- and blue-shifted and new…
Infrared bubble recognition in the Milky Way and beyond using deep learning
Shimpei Nishimoto, Toshikazu Onishi, Atsushi Nishimura +9
We propose a deep learning model that can detect Spitzer bubbles accurately using two-wavelength near-infrared data acquired by the Spitzer Space Telescope and JWST. The model is b…
Optical photon-counting observation of the Crab pulsar with Kanata telescope using prototype IMONY
Takeshi Nakamori, Kazuaki Hashiyama, Rin Sato +14
We have developed an optical photon-counting imaging system, IMONY, as an instrument for short-scale time-domain astronomy. In this study, we utilized a Geiger avalanche photodiode…
Encoding and Decoding Algorithms of ANS Variants and Evaluation of Their Average Code Lengths
Hirosuke Yamamoto, Ken-ichi Iwata
Asymmetric Numeral Systems (ANS) proposed by Jarek Duda are high-performance distortionless data compression schemes that can achieve almost the same compression performance as ari…
Topological phase diagram of the Haldane model on a Bishamon-kikko--honeycomb lattice
Sogen Ikegami, Kiyu Fukui, Shun Okumura +2
Topological flat bands have gained extensive interest as a platform for exploring the interplay between nontrivial band topology and correlation effects. In recent studies, strongl…
