Sparse modeling study of extracting charmonium spectral functions from lattice QCD at finite temperature
Junichi Takahashi, Hiroshi Ohno, Akio Tomiya
We present charmonium spectral functions extracted from Euclidean-time correlation functions using sparse modeling (SpM). SpM solves inverse problems by considering only the sparsi…
MobText-SISA: Efficient Machine Unlearning for Mobility Logs with Spatio-Temporal and Natural-Language Data
Haruki Yonekura, Ren Ozeki, Tatsuya Amano +2
Modern mobility platforms have stored vast streams of GPS trajectories, temporal metadata, free-form textual notes, and other unstructured data. Privacy statutes such as the GDPR r…
CNN-based Surface Temperature Forecasts with Ensemble Numerical Weather Prediction
Takuya Inoue, Takuya Kawabata
Due to limited computational resources, medium-range temperature forecasts typically rely on low-resolution numerical weather prediction (NWP) models, which are prone to systematic…
An independent hybrid imaging of Sgr A* from the data in EHT 2017 observations
Makoto Miyoshi, Yoshiaki Kato, Junichiro Makino
We propose that the ring structure found by the Event Horizon Telescope Collaboration (EHTC) as the black hole shadow of Sgr A*is an artifact by the bumpy PSF (Point Spread Functio…
Restoring Super-High Resolution GPS Mobility Data
Haruki Yonekura, Ren Ozeki, Hamada Rizk +1
This paper presents a novel system for reconstructing high-resolution GPS trajectory data from truncated or synthetic low-resolution inputs, addressing the critical challenge of ba…
Relative abundances of CO2, CO, and CH4 in atmospheres of Earth-like lifeless planets
Yasuto Watanabe, Kazumi Ozaki
Carbon is an essential element for life on Earth, and the relative abundances of major carbon species (CO2, CO, and CH4) in the atmosphere exert fundamental controls on planetary c…
