We aimed to investigate the association between smoking, alcoholic consumption, and betel quid chewing with oral cancer in a prospective manner. All male patients age ≥18 years who visited our clinic received an oral mucosa inspection. Basic data including personal habits were also obtained. A multivariate logistic regression model was utilized to determine(More)
This paper studies the tracking and almost disturbance decoupling problem of nonlinear system based on the feedback linearization and multilayered feedforward neural network approach. The feedback linearization and neural network controller guarantees exponentially global uniform ultimate bounded stability and the almost disturbance decoupling performance(More)
A 32-year-old man presented to the emergency department with a 2-day history of nonproductive cough, fever, severe sore throat, odynophagia, and dysphagia. A chest radiograph showed no significant finding, but the lateral view of the neck demonstrated ''vallecula'' and ''thumbprint'' signs (Figure 1). Significant laboratory findings were a white blood cell(More)
This paper studies the tracking and almost disturbance decoupling problem of nonlinear systems with uncertainties, based on the feedback linearization approach. The main contribution of this study is to construct a controller, under appropriate conditions, such that the resulting closed-loop system is valid for any initial condition and bounded tracking(More)
