Robust Wavelength Selection for Partial Least Squares Sugar Content Estimation Using Combinatorial Bayesian Optimization
Mitsunobu Kanebako, Ami S. Koshikawa, Masaru Hitomi +4
Wavelength selection is one of the important preprocessing methods in near-infrared spectroscopy to improve prediction accuracy and interpretability of spectral data. We formulate…
Magnetic order in nanoscale gyroid networks
Ami S. Koshikawa, Justin Llandro, Masayuki Ohzeki +3
Three-dimensional magnetic metamaterials feature interesting phenomena that arise from a delicate interplay of material properties, local anisotropy, curvature, and connectivity. A…
Response of the GAGG(Ce) scintillator to charged particles compared with the CsI(Tl) scintillator
T. Furuno, A. Koshikawa, T. Kawabata +7
GAGG(Ce) is a novel scintillator with a fast response and high light output without a hygroscopic nature. It is expected to be a useful detector for charged particles at high-count…
Combinatorial Black-box Optimization for Vehicle Design Problem
Ami S. Koshikawa, Masayuki Ohzeki, Masamichi J. Miyama +4
Black-box optimization minimizes an objective function without derivatives or explicit forms. Such an optimization method with continuous variables has been successful in the field…
Benchmark test of Black-box optimization using D-Wave quantum annealer
Ami S. Koshikawa, Masayuki Ohzeki, Tadashi Kadowaki +1
In solving optimization problems, objective functions generally need to be minimized or maximized. However, objective functions cannot always be formulated explicitly in a mathemat…
Observation of Coulomb-assisted nuclear bound state of -N system
S. H. Hayakawa, K. Agari, J. K. Ahn +95
In an emulsion-counter hybrid experiment performed at J-PARC, a absorption event was observed which decayed into twin single- hypernuclei. Kinematic calculations enabled a…
Observation of a Be double-Lambda hypernucleus in the J-PARC E07 experiment
H. Ekawa, K. Agari, J. K. Ahn +100
A double- hypernucleus, , was observed by the J-PARC E07 collaboration in nuclear emulsions tagged by the reaction. This event was interprete…
