Meshing Stiffness Calculation of Disposable Harmonic Drive under Full Load

open access: yesMachines, 2022
Mechanical equipment in the field of aerospace that is used only once is called disposable machinery. As a piece of typical disposable machinery, disposable harmonic gear exhibit stiffness failure with a large load.

Subharmonic transitions and Bloch-Siegert shift in electrically driven spin resonance [PDF]

open access: yes, 2015
We theoretically study coherent subharmonic (multi-photon) transitions of a harmonically driven spin. We consider two cases: magnetic resonance (MR) with a misaligned, i.e., non-transversal driving field, and electrically driven spin resonance (EDSR) of ...

Study of second and third harmonic generation from an indium tin oxide nanolayer: Influence of nonlocal effects and hot electrons [PDF]

open access: yes, 2020
We report comparative experimental and theoretical studies of the second and third harmonic generation from a 20 nm-thick indium tin oxide layer in proximity of the epsilon-near-zero condition. Using a tunable optical parametric amplifier, we record both

Perspectives in educating molecular pathologists on liquid biopsy: Toward integrative, equitable, and decentralized precision oncology

open access: yesMolecular Oncology, EarlyView.
Liquid biopsy enables minimally invasive, real‐time molecular profiling through analysis of circulating biomarkers in biological fluids. This Perspective highlights the importance of training pathologists through integrative educational programs, such as the European Masters in Molecular Pathology, to ensure effective and equitable implementation of ...

LINC01116, a hypoxia‐lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Unraveling the Vibration Mechanism in Robotic Harmonic Drive: Coupled Dynamics Under Cyclic Inertial Loading and Installation Errors

open access: yesMachines
As a key component in robots, the harmonic drive directly impacts the reliability and lifespan of the whole system. Due to the cyclic inertial loading and installation errors, the harmonic drive possesses unique but complicated vibration features.

Research on Nonlinear Dynamics Modeling and Simulation of Harmonic Gear Drive

open access: yesJixie chuandong, 2021
Due to the particularity of the structure,the hysteretic stiffness and dynamic friction belong to the inherent properties of harmonic gear drive. Traditional models consider the stiffness as a fixed stiffness or segmented stiffness model,and the friction

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Crack Propagation Simulation and Meshing Stiffness Analysis of Disposable Harmonic Gears

open access: yesJixie chuandong, 2023
The mechanical equipment in aerospace field that will not be reused after being used once is called disposable machinery. The failure of the flexible wheel is the most important factor affecting the performance of the disposable harmonic reducer.
