Investigation of factors affecting the performance of pinion bearing for gear unit of railway vehicle

open access: yesNihon Kikai Gakkai ronbunshu, 2019
If bearings for gear units of railway vehicles are damaged by seizing, parts of the bearings come off and damage the gear and the gear box, which may lead to the leakage of the gear oil and the defective rotation of the wheel sets.

Linear slider supported by squeezed air films with self-propulsion mechanism based on floating height difference

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Non-contact supports involving air or magnetic forces are used as guide supports for linear motion mechanisms. In the present study, non-contact supports are generated using the effect of the static pressure force produced by a squeezed air film.

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Variable stiffness element by granular jamming (Stiffness enhancement by a wrinkle-free outer membrane)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
A flexible bag containing particles becomes rigid when the air inside the element is evacuated. Variable stiffness elements using granular jamming have been used for haptic displays and robotic orthoses helped by the soft and lightweight body.

Rotor eddy-current loss in permanent magnet brushless machines [PDF]

open access: yes, 2004
This paper presents an analysis of the rotor eddy-current loss in modular and conventional topologies of permanent magnet brushless machine. The loss is evaluated both analytically and by time-stepped finite-element analysis, and it is shown that it can ...
