Validation of the Spinal Instability Neoplastic Score: A Retrospective Analysis
Introduction With improved survival rates of cancer patients, the incidence of spinal metastases is increasing. Spinal metastases increase the risk for pathological fractures that subsequently increase the risk of spinal instability, spinal cord ...

An Innovative High-Precision Scheme for a GPS/MEMS-SINS Ultra-Tight Integrated System
The Doppler-assisted error provided by a low-precision microelectromechanical system (MEMS) strapdown inertial navigation system (SINS) increases rapidly. Therefore, the bandwidth of the tracking loop for a global positioning system (GPS)/MEMS-SINS ultra-

A Novel SINS/IUSBL Integration Navigation Strategy for Underwater Vehicles
This paper presents a novel SINS/IUSBL integration navigation strategy for underwater vehicles. Based on the principle of inverted USBL (IUSBL), a SINS/IUSBL integration navigation system is established, where the USBL device and the SINS are both ...
