In this paper, an adaptive neural controller for a class of time-delay nonlinear systems with unknown nonlinearities is proposed. Based on a wavelet neural network (WNN) online approximation model, a state feedback adaptive controller is obtained by constructing a novel integral-type Lyapunov-Krasovskii functional, which also efficiently overcomes the(More)
An adaptive backstepping neural-network control approach is extended to a class of large-scale nonlinear output-feedback systems with completely unknown and mismatched interconnections. The novel contribution is to remove the common assumptions on interconnections such as matching condition, bounded by upper bounding functions. Differentiation of the(More)
In this paper, the adaptive neural network output-feedback stabilization problem is investigated for a class of stochastic nonlinear strict-feedback systems. The nonlinear terms, which only depend on the system output, are assumed to be completely unknown, and only an NN is employed to compensate for all unknown upper bounding functions, so that the(More)
BACKGROUND Reactivation of hepatitis B virus (HBV) is less common in lymphoma patients with prior resolved HBV infection [characterized by hepatitis B surface antigen (HBsAg)-negative/hepatitis B core antibody (HBcAb)-positive status] compared with chronic HBV infection (HBsAg positive) when receiving chemotherapy alone. The use of rituximab in chemotherapy(More)
This study mainly focused on the impact of Hepatitis B virus (HBV) infection on the prognosis of diffuse large B cell lymphoma (DLBCL) patients in rituximab era, using a Cox regression model to ascertain the prediction value of the serum HBV marker in survivals. Three hundred and eighty four DLBCL patients treated with rituximab, cyclophosphamide,(More)
AIMS We have recently shown that fenretinide preferentially targets CD34(+) cells of acute myeloid leukemia (AML), and here, we test whether this agent exerts the effect on CD34(+) cells of chronic myeloid leukemia (CML), which are refractory to imatinib. RESULTS As tested by colony-forming cell assays using clinical specimens, both number and size of(More)
This paper presents a T-S fuzzy hyperbolic model for unknown nonlinear systems, by constructing a new Lyapunov function, the stability conditions of the open-loop system are given via linear matrix inequalities (LMIs). Then the parallel distributed compensation (PDC) method is used to design a fuzzy controller, and the asymptotic stability conditions of the(More)
The past three decades have witnessed a great progress in the treatment of acute promyelocytic leukemia (APL). The current application of all-trans retinoic acid, arsenic trioxide (ATO), and anthracycline-based chemotherapies has been proved to be highly effective. Based on the risk factors of APL, optimization of the treatment emphasizes the role of ATO in(More)
