Heatwave Characteristics and Trends Across Eight Japanese Cities

open access: yesInternational Journal of Climatology, EarlyView.
Heatwaves occur with high likelihood across Japan. Strong north–south contrasts exist in heatwave characteristics. Southern locations experience more frequent, longer, and more intense heatwaves. Since 1955 there has been an increase in heatwave frequency, duration, and cumulative heat, particularly for nocturnal heatwaves. ABSTRACT This study provides

Algebraic invariants of links and 3-manifolds [PDF]

open access: yes, 2015
The goal of this thesis is to describe certain algebraic invariants of links, and try to modify them to obtain invariants of 3-manifolds. Racks and quandles are algebraic structures that were invented to give invariants of knots and links.

Collagen‐membrane‐covered matrix‐associated chondrocyte implantation improves safety over periosteum‐covered MACI for large knee cartilage defects: A real‐world data analysis in the registry study

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This registry study aimed to evaluate the safety and effectiveness of collagen membrane‐covered matrix‐associated autologous chondrocyte implantation (cMACI) versus periosteum‐covered MACI (pMACI) for large knee cartilage defects (Outerbridge III–IV, ≥4 cm²) in the femorotibial and/or patellofemoral joints with a minimum 2‐year follow ...

Legendrian knots in surgery diagrams and the knot complement problem

open access: yes, 2016
The famous knot complement theorem by Gordon and Luecke states that two knots in the 3-sphere are equivalent if and only if their complements are homeomorphic. By contrast, this does not hold for links in the 3-sphere or for knots in general 3-manifolds.

Patient‐Reported Outcomes of Palatopharyngeal Surgery Without Tonsillectomy: A Meta‐Analysis

open access: yesThe Laryngoscope, EarlyView.
Palatopharyngeal surgery without tonsillectomy leads to clinically meaningful improvements in daytime sleepiness and snoring, but patient‐reported outcomes vary markedly by surgical technique. Suture‐based procedures, muscle relocation, cold‐steel approaches, and powered instruments show the largest and durable benefits, with no evidence of effect ...

Knots, Links, and 4-Manifolds

open access: yes, 1997
. In this paper we investigate the relationship between isotopy classes of knots and links in S 3 and the diffeomorphism types of homeomorphic smooth 4-manifolds.

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,
