Technique of tooth relieving of worm hobs for cutting Novikov gears with double lines of action [PDF]
MATEC Web of Conferences, 2020 Worm hobs for cutting Novikov gears have the profile of a generating worm, which varies not only in a radius, but also in a sign of curvature. A technique for relieving tooth flanks of these hobs by disk grinding wheel is developed.

PROFILE GEAR GRINDING TEMPERATURE DETERMINATION
Transactions of Kremenchuk Mykhailo Ostrohradskyi National University, 2018 The paper is devoted to solving an important scientific and technical problem of determining the profile gear grinding temperature based on the choice of simple but at the same time adequate solution from the available analytical ones. The initial prerequisite for the paper developing concept is that of a moving heat source, which was originally ...

Quantitative correction method for the grinding errors of cycloidal gears in precision reducer
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020 The motion accuracy of a precision reducer mainly depends on the transmission quality of the cycloid-pin gear, which is determined by the grinding accuracy of the cycloidal gear. The poor meshing characteristics caused by grinding errors in the cycloidal

Molecular Oncology, EarlyView.LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Characterizing Cutaneous α‐Synuclein Deposition and Seeding Activity in Parkinson's Disease Subtypes
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cutaneous phosphorylated α‐synuclein (p‐syn) and α‐synuclein seeding activity are promising biomarkers for Parkinson's disease (PD), but their clinical value remains uncertain due to disease heterogeneity. This study evaluates these two biomarkers in PD patients to inform phenotype‐specific diagnosis and disease severity assessment ...
