Long-term changes in water quality in the Seto Inland Sea, Japan: 53-year observations (1973–2025)

Abstract We analyzed 53 years (1973–2025) of water quality observations collected through the Fisheries Monitoring Program in the Seto Inland Sea (SIS), one of the longest-standing coastal monitoring efforts in Japan. Using climatological anomalies and non-parametric statistical...

Automatic Termination Strategy of Inelastic Neutron-scattering Measurement Using Bayesian Optimization for Bin-width Selection

Currently, an excessive amount of event data is being obtained in four-dimensional inelastic neutron-scattering experiments. A method for automatic bin-width optimization of multidimensional histograms has been developed and recently validated on real inelastic neutron-scattering...

A Bayesian Approach to Nuclear Spin Relaxation Phenomena in Topological Kondo Insulator SmB 6

In studies of the promising topological Kondo insulator (TKI) candidate SmB 6 , nuclear magnetic resonance (NMR) measurements of the spin–lattice relaxation rate, 1/T 1 , have provided crucial insights into this compound: for example, the unique opening of a small hybridization g...
