Iwahashi Zenbei's Sunspot Drawings in 1793 in Japan
Hisashi Hayakawa, Kiyomi Iwahashi, Harufumi Tamazawa +2
Three Japanese sunspot drawings associated with Iwahashi Zenbei (1756-1811) are shown here from contemporary manuscripts and woodprint documents with the relevant texts. We reveale…
SPICA and the Chemical Evolution of Galaxies: The Rise of Metals and Dust
J. A. Fernández-Ontiveros, L. Armus, M. Baes +33
The physical processes driving the chemical evolution of galaxies in the last cannot be understood without directly probing the dust-obscured phase of star-for…
Records of Auroral Candidates and Sunspots in Rikkokushi, Chronicles of Ancient Japan from Early 7th Century to 887
Hisashi Hayakawa, Kiyomi Iwahashi, Harufumi Tamazawa +5
In this article, we present the results of the surveys on sunspots and auroral candidates in Rikkokushi, Japanese Official Histories from the early 7th century to 887 to review the…
Matrix Method for Persistence Modules on Commutative Ladders of Finite Type
Hideto Asashiba, Emerson G. Escolar, Yasuaki Hiraoka +1
The theory of persistence modules on the commutative ladders provides an extension of persistent homology. However, an efficient algorithm to compute the generalized pers…
Records of Sunspots and Aurora Candidates in the Chinese Official Histories of the Yuán and Míng Dynasties during 1261-1644
Hisashi Hayakawa, Harufumi Tamazawa, Yusuke Ebihara +4
Records of observations of sunspots and auroras in pre-telescopic historical documents provide useful information about past solar activity both in long-term trends and short-term…
Splitting formulas for the rational lift of the Kontsevich integral
Delphine Moussard
Kricker defined an invariant of knots in homology 3-spheres which is a rational lift of the Kontsevich integral, and proved with Garoufalidis that this invariant satisfies splittin…
One-dimensional plasmonic hotspots located between silver nanowire dimers evaluated by surface-enhanced resonance Raman scattering
Tamitake Itoh, Yuko S Yamamoto, Yasutaka Kitahama +1
Hotspots of surface-enhanced resonance Raman scattering (SERRS) are localized within 1 nm at gaps or crevices of plasmonic nanoparticle (NP) dimers. We demonstrate SERRS hotspots w…
Minimax Optimal Estimators for Additive Scalar Functionals of Discrete Distributions
Kazuto Fukuchi, Jun Sakuma
In this paper, we consider estimators for an additive functional of , which is defined as , from i.i.d. random samples drawn from a discrete distr…
