Design and Workspace Analysis of Cable-rod Hybrid Drive Parallel Mechanism
A new type of cable-rod hybrid drive parallel mechanism is proposed,and the overall device model is built in SolidWorks. The inverse kinematics model of the mechanism is derived by using the space vector analysis method.

2RPS/2SPS Parallel Mechanism and Kinematics Analysis
Based on constraint spiral theory,the modified Grübler-Kutzbach formula is used to analyze the degree of freedom of 2RPS/2SPS parallel mechanism. The inverse positional solution equation is established by the space coordinate transformation equation and ...

Research of Design and Kinematic Characteristic of a 3-UPS/RPP Parallel Mechanism
A new 3-DOF parallel mechanism 3-UPS/RPP is designed, which can realize two shifts and one rotation. Based on the traditional 3-UPS structure, a constrained branched chain of RPP structure is added to the structure.

ABSTRACT Background Platinum‐based chemotherapy is known to cause severe and debilitating hearing loss, but unlike cisplatin, the true incidence of carboplatin‐induced hearing loss remains unclear. We evaluated functional hearing outcomes in children receiving carboplatin to determine the incidence and severity of ototoxicity. Procedure We identified a

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.
