For planar closed-loop structures with clearances, the angular and positional error uncertainties are studied. By using the vector translation method and geometric method, the boundaries of the errors are analyzed. The joint clearance is considered as being distributed uniformly in a circle area. A virtual link projection method is proposed to deal with the clearance affected length error probability density function (PDF) for open-loop links. The error relationship between open loop and closed loop is established. The open-loop length PDF and the closed-loop angular error PDF both approach being Gaussian distribution if there are many clearances. The angular propagation error of multi-loop structures is also investigated by using convolution. The positional errors of single and multiple loops are both discussed as joint distribution functions. Monte Carlo simulations are conducted to verify the proposed methods.

<p><strong>Background:</strong> Circular Ribonucleic Acid (circRNA) is a type of RNA that has been found in recent years and is a closed loop structure widely found in eukaryotic cells. <strong>Present situation:</strong> The circRNA is stable in nature, highly conserved and tissue and disease specific, and regulates target gene expression at the transcriptional or posttranscriptional level, which is related to the occurrence and development of tumors. YAP (Yes-associated protein) is the main effector of Hippo signaling pathway. It is found that YAP level is closely related to cell proliferation and apoptosis, tissue organ size control and tumorigenesis. <strong>Aim:</strong> to study the correlation between circRNA and YAP in tumors.</p>
