Research on Influence of Joint Clearance on Precision of 3-TPT Parallel Robot [PDF]

Mechanical Sciences, 2019
The error model of the working accuracy of parallel mechanism was established in this paper. The D-H matrix method and error independent method were used to analyze the clearance error of mechanism joint based on the inverse position kinematics solution.

Spatial revolute joints with clearance and friction for dynamic analysis of multibody mechanical systems [PDF]

, 2016
A study on the effects of dry spatial revolute joints with clearance and friction is delivered through this work. Both radial and axial clearances are taken into consideration which makes the model more realistic for three-dimensional motion.

Influence of clearance on the time-dependent performance of the hip following hemiarthroplasty: a finite element study with biphasic acetabular cartilage properties [PDF]

, 2014
Hip hemiarthroplasty is a common treatment for femoral neck fracture. However, the acetabular cartilage may degenerate after hemiarthroplasty leading to postoperative failure and the need for revision surgery.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Ultrasonic scanning system for in-place inspection of brazed tube joints [PDF]

, 1973
A miniaturized ultrasonic scanning system for nondestructive in-place, non-immersion testing of brazed joints in stainless-steel tubing is described. The system is capable of scanning brazed tube joints, with limited clearance access, in 1/4 through 5/8 ...

Tumor and germline testing with next generation sequencing in epithelial ovarian cancer: a prospective paired comparison using an 18‐gene panel

Molecular Oncology, EarlyView.
Genetic testing in epithelial ovarian cancer includes both germline and tumor‐testing. This approach often duplicates resources. The current prospective study assessed the feasibility of tumor‐first multigene testing by comparing tumor tissue with germline testing of peripheral blood using an 18‐gene NGS panel in 106 patients.

A Principal Components Analysis Approach to Quantifying Foot Clearance and Foot Clearance Variability [PDF]

, 2019
Low foot clearance and high variability may be related to falls risk. Foot clearance is often defined as the local minimum in toe height during swing; however, not all strides have this local minimum.

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

Molecular 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 ...

Normalized-constrained approach for joint clearance design of deployable overconstrained Myard 5R mechanism

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015
This paper proposes a normalized-constrained approach for the joint clearance design of deployable overconstrained Myard 5R mechanism. Firstly, the overconstrained mobility characteristic of Myard 5R mechanism is analyzed, we show that the dimensional ...
