Selective Ensemble Mean Technique for Tropical Cyclone Track Forecasts Using Multi-Model Ensembles

Masato Nishimura; Munehiko Yamaguchi

Tropical Cyclone Research and Review, Vol. 4 No. 2 · 2015 · English · DOAJ Scopus

ABSTRACT: A selective ensemble mean technique for tropical cyclone (TC) track forecasts, which excludes from the ensemble those models that have large position errors at short lead times, was applied to a set of TC track forecasts produced by 11 operational global deterministic models. The position…

The Q-Exponential Decay of Subjective Probability for Future Reward: A Psychophysical Time Approach

Taiki Takahashi; Shinsuke Tokuda; Masato Nishimura et al.

Entropy, Vol. 16 No. 10 · 2014 · English · DOAJ Scopus

This study experimentally examined why subjective probability for delayed reward decays non-exponentially (“hyperbolically”, i.e., q ˂ 1 in the q-exponential discount function) in humans. Our results indicate that nonlinear psychophysical time causes hyperbolic time-decay of subjective probability…

Abstract Background Hexadecyl-immobilized porous cellulose beads (HICBs) can be used to remove β2-microglobulin, as well as several inflammatory cytokines and free protein-binding uremic toxins (PBUTs). Interleukin-6 and PBUT levels have been associated with oxidative stress and/or cardiovascular…

Association Between Disturbed Serum Phosphorus Levels and QT Interval Prolongation

Sho Sasaki; Kiichiro Fujisaki; Masato Nishimura et al.

Kidney International Reports, Vol. 9 No. 6 · 2024 · English · DOAJ Scopus

Introduction: QT interval prolongation is a risk factor for fatal arrhythmias and other cardiovascular complications. QT interval prolongation in patients on hemodialysis (HD) is not well understood. Hypocalcemia is a suspected, but poorly verified etiology in these patients, and the association…

Hemodialysis vascular sound index as a diagnostic tool for vascular access stenosis: a prospective matched observational study

Yasumasa Hitomi; Naoki Suzuki; Toshiya Enmeiji et al.

BMC Nephrology, Vol. 27 No. 1 · 2026 · English · DOAJ Scopus

Abstract Background Vascular access (VA) monitoring is critical for hemodialysis patients. While vascular ultrasound (US) provides high diagnostic accuracy for VA stenosis, its reliance on equipment and trained operators can limit routine implementation. The Hemodialysis Vascular Sound Index…

Toshiya Matsuzaki; Takeshi Iwasa; Takako Kawakita et al.

Reproductive Medicine and Biology, Vol. 17 No. 3 · 2018 · English · DOAJ Scopus

Abstract Case Approximately 3%‐25% of cases of endometrial carcinoma (EC) or atypical endometrial hyperplasia (AH) occur in women aged

Efficacy of tenapanor in managing hyperphosphatemia and constipation in hemodialysis patients: A randomized controlled trial

Naoki Suzuki; Yuuki Takeda; Akie Kabuto et al.

PLOS One, Vol. 20 No. 6 · 2025 · English · PLOS Scopus

Introduction: Tenapanor is a minimally absorbed, small-molecule inhibitor of sodium/hydrogen exchanger 3 and thus suppresses sodium absorption in the gastrointestinal tract. It is approved by the FDA for the treatment of hyperphosphatemia in dialysis patients. This randomized controlled trial…

Tumor T 1 Relaxation Time for Assessing Response to Bevacizumab Anti-Angiogenic Therapy in a Mouse Ovarian Cancer Model

Murali K. Ravoori; Masato Nishimura; Sheela P. Singh et al.

PLOS ONE, Vol. 10 No. 6 · 2015 · English · PLOS Scopus

Purpose: To assess whether T1 relaxation time of tumors may be used to assess response to bevacizumab anti-angiogenic therapy. Procedures: 12 female nude mice bearing subcutaneous SKOV3ip1-LC ovarian tumors were administered bevacizumab (6.25ug/g, n=6) or PBS (control, n=6) therapy twice a week for…
