Mathematics Modelling of Hobbing Gear with Arbitrary Tooth Profile and Investigation [PDF]

open access: yes, 2011
Based on space meshing theory, the coordinate relation between the hob and the gear is established using the general tool which is used to product a standard involute gear. The space conversion matrix of hobbing movement is deduced.

Expression of gear-tooth-flank deviations for Hobbing-Machine-Diagnosis system (Learning-data collection through hobbing simulation and their compression with network representation)

open access: yesNihon Kikai Gakkai ronbunshu, 2021
A hobbed gear has pitch, profile, and helix deviations caused by various factors. However it is hard for even experts to specify which factors cause individual deviations from the measured ones. Therefore, a hobbing-machine-diagnosis system could play a

Exceptional Thermal Conductivity in Printed Dielectrics through Compositional and Microstructural Design

open access: yesAdvanced Materials, Volume 37, Issue 32, August 14, 2025.
A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Neurodegenerative and Neurodevelopmental Roles for Bulk Lipid Transporters VPS13A and BLTP2

open access: yesMovement Disorders, Volume 40, Issue 7, Page 1356-1368, July 2025.
Abstract Background Bridge‐like lipid transfer proteins (BLTPs) mediate bulk lipid transport at membrane contact sites. Mutations in BLTPs are linked to both early‐onset neurodevelopmental and later‐onset neurodegenerative diseases, including movement disorders.

Signature Dynamics of Development in Second Language Sociolinguistic Competence: Evidence From an Intensive Microlongitudinal Study

open access: yesLanguage Learning, Volume 74, Issue 3, Page 707-743, September 2024.
Abstract This study is the first to explore microdevelopment in sociolinguistic evaluative judgments of standard German and Austro‐Bavarian dialect by adult second language learners of German by using dense time serial measurements. Intensive longitudinal data (10 observations per participant) were collected from four learners at approximately weekly ...
