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.

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma

open access: yesMolecular Oncology, EarlyView.
Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

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

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

无级变速谐波传动原理与传动比计算

open access: yesJixie chuandong, 2006
By making relative movement between the flexible spline and rigid spline,either of them has a taper hole or taper surface,this results in the perimeter difference 2((R-r)of flexible spline and rigid spline continuous variation, then realizes continuous ...

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.
