A numerical simulation of the geomagnetic sudden commencement: 1. Generation of the field-aligned current associated with the preliminary impulse
Shigeru Fujita,Shigeru Fujita,Takashi Tanaka,T. Kikuchi,Keizo Fujimoto,Keisuke Hosokawa,M. Itonaga +6 more
TL;DR: In this paper, the authors present a quantitative model of the preliminary impulse model presented by Araki [1994] by using a numerical simulation and show that the PI current is first excited as an enhanced Chapman-Ferraro current in the magnetopause and next turns to the magnetosphere along the wavefront of the compressional signal launched by the impulse.
Journal ArticleDOI
A numerical simulation of the geomagnetic sudden commencement: 2. Plasma processes in the main impulse
TL;DR: In this paper, a geomagnetic sudden commencement (SC) model was studied numerically based on a model of buffeting the magnetosphere by a solar wind density impulse, and two successive current systems in the main impulse (MI) phase were treated.
Journal ArticleDOI
The nature of reflection and mode conversion of MHD waves in the inductive ionosphere: Multistep mode conversion between divergent and rotational electric fields
Akimasa Yoshikawa,M. Itonaga +1 more
TL;DR: In this paper, the authors analyzed the nature of reflection and mode conversion of MHD waves at the high-latitudinal inductive ionosphere, based on the current conservation law of wave modes.
Journal ArticleDOI
A numerical simulation of the Pi2 pulsations associated with the substorm current wedge
TL;DR: In this paper, the authors studied the transient behavior of MHD perturbations in the inner magnetosphere induced by an impulsive localized eastward current (source current) as a model of Pi2 pulsations.
Journal ArticleDOI
Ultrasensitive detection of SARS-CoV-2 nucleocapsid protein using large gold nanoparticle-enhanced surface plasmon resonance
Taka-aki Yano,Taira Kajisa,Masayuki Ono,Yoshiya Miyasaka,Yuichi Hasegawa,Atsushi Saito,Kunihiro Otsuka,Ayuko Sakane,Takuya Sasaki,Koji Yasutomo,Rina Hamajima,Yutaka Kanai,Takeshi Kobayashi,Yoshiharu Matsuura,M. Itonaga,Takeshi Yasui +15 more
TL;DR: In this paper , the authors used surface plasmon resonance (SPR) techniques to detect SARS-CoV-2 nucleocapsid protein (N protein) using nanoparticle-enhanced surface resonance.
