Mobility analysis of parallel mechanisms based on screw theory and mechanism topology
Advances in Mechanical Engineering, 2015 A practical method for mobility analysis of mechanisms is presented in this article, which is based on the screw theory and the topology structure of mechanisms. The proposed method can be summarized as one core principle and two key techniques. The core

Liquid biopsy‐based diagnostic evaluation of hypermethylated CpG sites for ovarian cancer diagnosis
Molecular Oncology, EarlyView.This schematic outlines the workflow from biomarker identification to duplex MethyLight assay validation for epithelial ovarian cancer diagnosis using cfDNA‐based liquid biopsy. Initial screening of hypermethylated CpG candidates (cg02957270, cg10061138 cg00480298, COL2A1) was performed in tissue using ARMS‐PCR, COBRA, qPCR and image analysis. Selected

Designated Confirmer Signatures and Public-Key Encryption are Equivalent [PDF]
, 2007 The concept of designated confirmer signatures was introduced by Chaum [Cha94] to improve a shortcoming of undeniable signatures. The present paper formalizes the definition of designated confirmer signatures and proves that a designated confirmer signature scheme is equivalent to a public-key encryption scheme with respect to existence.

Molecular 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.
