Purpose To investigate the associated factors and change trajectories of quality of life (QoL), global outcome, and post-concussion symptoms (PCS) over the first year following mild traumatic brain injury (mTBI). Methods This was a prospective longitudinal study of 100 participants with mTBI from neurosurgical outpatient departments in Chiayi County District Hospitals in Taiwan. The checklist of...
This study investigates the existence of stabilizing switching rules among a class of unstable nonlinear systems. A high-order checking condition and an associated stabilizing switching rule are presented to implement the stabilizability of the switched systems. An illustrative example is also given to demonstrate the usage and the benefits of the proposed scheme
Issues concerning the construction of quadratically stabilizing switching laws among N unstable linear systems are studied in this paper. The obtained results are also employed to study the existence of control laws and quadratically stabilizing switching laws among a class of unstabilizable linear control systems. Finally, the illustrative examples and simulation results show the feasibility and...
